[Abstract] (11) [HTML] (0) [PDF 0.00 Byte] (0)

Abstract:
Background: The incidence of severe fever with thrombocytopenia syndrome (SFTS) has been steadily increasing over the years, accompanied by a persistently high mortality rate. Organ injury may serve as a potential contributor to poor clinical outcomes. This study aimed to summarize the characteristics and patterns of organ injury in patients diagnosed with SFTS. Methods: A retrospective analysis was conducted on patients with SFTS admitted to the First Affiliated Hospital with Nanjing Medical University (Jiangsu Provincial Hospital) between January 2023 and December 2024. During hospitalization, concurrent organ injuries were recorded and statistically analyzed. Logistic regression analysis was performed to evaluate the association between organ injury and prognosis. Furthermore, a nomogram was developed to predict discharge outcomes based on organ injury assessment in SFTS patients. Results: A total of 284 SFTS patients were enrolled in this study, among whom 252 (88.7%) exhibited signs of organ injury. Cardiac injury was most commonly observed. Multivariate logistic regression analysis revealed that pancreatic injury (OR=3.17, 95%CI: 1.28-8.00, P=0.012), renal injury (OR=8.64, 95%CI: 3.54-22.29, P<0.001), pulmonary injury (OR=4.82, 95%CI: 2.01-11.98, P<0.001), and cerebral injury (OR=3.25, 95%CI: 1.34-7.90, P=0.009) were independently associated with increased risk of in-hospital mortality in SFTS patients. The constructed nomogram demonstrated strong predictive performance for discharge outcomes. Internal validation using the bootstrap method (resampling=1000) showed an average area under the ROC curve of 0.937 (95%CI: 0.910-0.965). Conclusion: The majority of SFTS patients experienced concurrent organ injuries. Among these, pancreatic, renal, pulmonary, and cerebral injuries were significantly associated with increased mortality risk.

Abstract:
Objective: The present study aimed to explore the D-Dimer cutoff values for predicting Pulmonary Thromboembolism after Cesarean Section. Methods: This study recruited 198 women after cesarean section with suspected PE symptoms in Women’s Hospital of Nanjing Medical University from January 2018 to December 2024. Among them, 33 patients who were diagnosed as PE by CTPA were divided intthe study group, and the 165 patients who were not diagnosed as PE by CTPA during the same period were divided into the control group. Analyze the age, Body Mass Index (BMI), gestational age at delivery (weeks)，number of fetuses, surgical indications, risk factors for VTE after delivery, D-dimer (mg/L) within postpartum 24 hours and the time of using LMWH after cesarean section. Draw the receiver operating characteristic curve (ROC) of D-dimer to determine the optimal sensitivity and specificity of the D-dimer value, with the area under the curve (AUC) used to evaluate the cut-off value. Analyze the risk factors for PE and calculate the odds ratio (OR) with a 95% confidence interval. Result: The D-dimer level in the PE group was (8.98 ± 6.91) mg/L, significantly higher than that in the non-PE group (4.03 ± 2.08) mg/L (P < 0.05), indicating that D-dimer is a strong predictor of PE and should be prioritized in clinical practice. The initiation of anticoagulation therapy in the PE group was delayed compared to the non-PE group, with a statistically significant difference, suggesting that early anticoagulation—when bleeding risk is low—plays a crucial role in preventing PE after cesarean delivery. The optimal cut-off value of D-dimer within 24 hours post-cesarean was 7.48 mg/L, with a specificity of 93.9% and sensitivity of 62.4%. The area under the curve (AUC) was 0.75 (95% CI: 0.652–0.848, P = 0.000), demonstrating significant diagnostic value for PE. When the D-dimer cut-off was adjusted to 1.59 mg/L, the sensitivity and specificity were 100% and 43.2%, respectively, with the highest Youden index for negative predictive value. This threshold may be particularly meaningful for early PE screening after cesarean delivery. Prolonged immobilization and D-dimer levels were identified as two independent risk factors for PE. Notably, D-dimer was a continuous risk factor (OR = 1.58), meaning that for every 1 mg/L increase in D-dimer, the risk of PE increased by 58%. Conclusion: This study conducted a preliminary exploration of the D-dimer cut-off value at 24 hours after cesarean delivery, aiming to establish a more convenient and safer screening method to improve the identification of postoperative PE. This approach could facilitate timely intervention and reduce unnecessary imaging examinations.

Abstract:
Objective: To conduct an in-depth analysis of the key factors influencing the risk of malnutrition in elderly diabetic patients with cognitive frailty (CF) and to construct an accurate risk prediction nomogram model based on these factors. Methods: A cross-sectional study design was adopted, enrolling 124 elderly diabetic patients with CF admitted to the Department of Geriatric Endocrinology, the First Affiliated Hospital of Nanjing Medical University between January 2023 and December 2024. The study instruments included: a general information questionnaire, the Fried Phenotype Frailty scale, the Montreal Cognitive Assessment scale, the Geriatric Depression Scale (GDS), the Self-Rating Anxiety Scale, and the Mini Nutritional Assessment scale. Basic patient information was collected, and assessments were made for frailty, cognitive function, psychological status, and malnutrition risk. Multivariate logistic regression analysis was used to identify influencing factors for malnutrition risk, and the R language "rms" package was used to construct the prediction model and draw the nomogram. Model validation included Receiver Operating Characteristic (ROC) curve analysis, the Hosmer-Lemeshow test, assessment of the Concordance Index (C-index), and the plotting of a calibration curve. Results: The malnutrition risk rate among the 124 elderly diabetic patients with CF was 67.7% (84/124). These 84 patients were assigned to the malnutrition risk group, and the remaining 40 were assigned to the well-nourished group. Significant differences (P < 0.05) were found between the two groups in terms of age, marital status, body mass index (BMI), GDS score, albumin, prealbumin, transferrin, and hemoglobin levels. Age, marital status, BMI, GDS score, albumin, and prealbumin levels were identified as independent predictors of malnutrition risk in elderly diabetic patients with CF (P < 0.05). The nomogram model constructed based on these influencing factors had a C-index of 0.781 [95% CI (0.695-0.867)]. The Hosmer-Lemeshow test indicated a good fit for the nomogram model (χ2 statistic = 5.22, corresponding P-value = 0.73). Decision curve analysis showed that when the threshold probability ranged from 0 to 0.67, the net benefit rate of using this nomogram model to predict malnutrition risk in elderly diabetic patients with CF was > 0. Conclusion: In elderly diabetic patients with CF, age, marital status, BMI, GDS score, albumin, and prealbumin levels are key factors influencing the risk of malnutrition. The established risk prediction model demonstrates moderate predictive performance and good clinical application value for assessing the risk of malnutrition in this patient population.

Abstract:
Abstract: Objective:To analyze the factors associated with prolonged postoperative hospital stay (≥30 days) after distal pancreatectomy (DP), identify independent risk factors, and provide a basis for optimizing perioperative management. Methods:A retrospective analysis was conducted on 1215 patients who underwent DP at a single center from January 2020 to June 2024. Based on postoperative hospital stay, patients were divided into two groups: ≥30 days (80 cases) and <30 days (1135 cases). Univariate analysis was used to compare differences in clinical characteristics between the two groups, and multivariate logistic regression was employed to identify independent risk factors. Results: Among the 1215 DP cases, 80 (6.6%) had a postoperative hospital stay ≥30 days. Univariate analysis revealed that gender, age, tumor type, modified Appleby procedure, combined organ resection, combined vascular resection, dissection of the Heidelberg triangle, as well as complications such as pancreatic fistula, delayed gastric emptying (DGE), postoperative bleeding, and chylous fistula were significantly associated with prolonged postoperative hospital stay (P < 0.05). Multivariate logistic regression analysis demonstrated that modified Appleby procedure (OR = 3.167, P = 0.007), combined organ resection (OR = 3.334, P < 0.001), postoperative bleeding (OR = 4.148, P = 0.025), DGE (OR = 10.482, P < 0.001), intra-abdominal infection (OR = 5.718, P < 0.001), chylous fistula (OR = 2.457, P = 0.022), sepsis (OR = 13.485, P < 0.001), and postoperative invasive interventions (OR = 6.045, P < 0.001) were independent risk factors for a hospital stay ≥30 days. Conclusion: Prolonged postoperative hospital stay (≥30 days) after distal pancreatectomy is associated with various perioperative factors. Developing individualized diagnostic and treatment strategies targeting high-risk factors and optimizing management can help reduce the length of hospital stay.

Abstract:
Objective: To investigate the clinicopathological features, immunophenotype and molecular genetic changes of switch/sucrose non-fermentable complex (SWI/SNF) complex deficient tumors in digestive system, and to analyze the diagnosis and differential diagnosis points. Methods: The clinical data of 31 patients with SWI/SNF complex deficient carcinoma of digestive system were collected. The histological morphology, immunohistochemical results and molecular changes were observed and analyzed. Results: Among the 31 patients, 19 were male and 12 were female, aged 43-80 years, mean age 64 years, median age 66 years. Location of disease: lower esophagus (gastroesophageal junction) 1 case, stomach 7 cases, right colon 3 cases, pancreas 18 cases, ampulla 2 cases. Histologically, 15 tumors were undifferentiated carcinoma, showing diffuse, solid, or nested, streaked, or pseudoglandular pattern of tumor cells, coagulative necrotic areas were seen in most cases. The tumor cells were mainly epithelioid cells with poor adhesion, rich cytoplasm, light staining or eosinophilic, slightly rough or vacuolar nuclear chromatin, obvious nucleoli, pathological mitotic figures were easy to see.16 cases were poorly to moderately differentiated ductal adenocarcinoma, adenosquamous carcinoma or intraductal papillary mucinous tumor (IPMN) with associated invasive carcinoma. Immunophenotype: 14/15 cases of undifferentiated carcinoma showed BRG1 loss expression, 1 case of undifferentiated carcinoma in pancreas showed INI1 partial loss expression, but BRG1 retained expression. CK-pan expression was negative or scattered in 4/15 cases of tumor cells, other epithelial markers were occasional positive or mostly negative in some tumor cells. 7/13 Syn tumor cells were weakly to moderately positive, 2 of them were weakly positive for CD56 or INSM1, and all of them were negative for CgA. BRG1 expression was retained in 16 pancreatic/ampullary carcinomas, INI1 expression was partially lost or decreased in 8 of 16 pancreatic/ampullary carcinomas, and retained in 8 of 16 pancreatic/ampullary carcinomas.22 patients were followed up, 6 patients died. Molecular pathology: SMARCB1 gene mutation was found in 14/16 cases of pancreatic or ampullary cancer, SMARCA4 gene mutation was found in 2/16 cases, KRAS gene mutation was found in all cases, and TP53 gene mutation was found in 14/16 cases. conclusion: SWI/SNF complex deficient tumor is a rare and highly malignant tumor, some of them are undifferentiated carcinomas without specific differentiation features. Extragastrointestinal SWI/SNF complex deficient carcinoma may have more differentiated adenocarcinoma morphology. Understanding its histological and immunohistochemical expression characteristics may suggest the detection of SWI/SNF proteins such as BRG1 and INI1 to reduce missed diagnosis and misdiagnosis. SWI/SNF-related gene mutations were associated with KRAS and TP53 gene mutations in pancreatic cancer.

Abstract:
Objective To investigate the effect and mechanism of narrow-band ultraviolet B (NB-UVB) in promoting vitamin D (VD) metabolism and alleviating imiquimod (IMQ) induced psoriasis like dermatitis in mice. Method C57BL/6 mice were treated with IMQ cream on the back skin to induce psoriasis like dermatitis. The levels of VD metabolites 25(OH)D3 and 1,25(OH)2D3 in serum were detected, as well as the expression of VD receptor (VDR) mRNA in the skin lesions; After determining the irradiation energy of NB-UVB irradiated mice, the model group combined with NB-UVB irradiation was performed to observe mouse skin lesions. The levels of 25(OH)D3, 1,25(OH)2D3 in serum, VDR and inflammatory factors (IL-17A, IL-23, TNF-α、IL-1β) mRNA expression and inflammatory factors protein contents in skin lesions, and the proportion of CD3+ CD4+ IL-17A+ T cells were detected. After pretreatment with the specific inhibitor Dafadine-A to block CYP27A1 activity (cytochrome P450 family 27 subfamily A, polypeptide 1, a key enzyme in vitamin D metabolism), the mice underwent psoriasiform dermatitis induction followed by NB-UVB irradiation. Skin lesions were observed, the proportion of CD3+ CD4+ IL-17A+ T cells, inflammatory factors and VDR mRNA expression in the skin lesions, and serum levels of 25(OH)D3 and 1,25(OH)2D3 were detected. Results The levels of 25(OH)D3 and 1,25(OH)2D3 in the serum of psoriasis like mouse models and the mRNA expression of VDR in skin lesions were significantly reduced. After NB-UVB irradiation on a psoriasis like mouse model, compared to the model group, the levels of 25(OH)D3, 1,25(OH)2D3 in the serum of the irradiated mice and the mRNA expression of VDR in the skin lesions were upregulated. The mRNA expression and content of inflammatory factors in the skin lesions were downregulated, and the proportion of IL-17A secreting CD3+ CD4+ T cells was significantly reduced. Compared to the IMQ+NB-UVB group, Dafadine-A pretreated mice showed significantly decreased serum levels of 25(OH)D3 and 1,25(OH)2D3, reduced VDR mRNA expression in skin lesions, along with significantly increased proportions of CD3+ CD4+ IL-17A+ T cells and elevated inflammatory cytokine levels in lesions. Conclusion NB-UVB irradiation ameliorates psoriasiform dermatitis and cutaneous inflammation in mice by promoting vitamin D metabolic pathways. Importantly, specific inhibition of CYP27A1 markedly attenuates the therapeutic effects of NB-UVB on both psoriatic skin lesions and associated inflammatory responses.

Abstract:
Objective: To separate a new important component 5-Hydroxymethyl-2-furfural (5-HMF) in cigarette smoke and provide material guarantee for evaluating its role in the respiratory system injury caused by smoking. Methods: A combination of liquid-liquid extraction and sephadex LH-20 column chromatography was used to extract and purify 5-HMF from the cigarette smoke extract (CSE) dissolved in chloroform. First, the total extract of cigarette smoke (CSE) was subjected to two consecutive liquid-liquid extractions with double-distilled water to transfer 5-HMF from the chloroform phase to the aqueous phase. Then, sephadex LH-20 was employed to separate 5-HMF from the aqueous phase. The efficiency of the extraction and separation processes was determined using high performance liquid chromatography-ultraviolet detection (HPLC-UV). GraphPad Prism software was used for two-way analysis of variance (Two-way ANOVA) and Tukey’s multiple comparisons test to evaluate the stability and reproducibility of the method. Results: The two-step liquid-liquid extraction transferred approximately 92.18% of 5-HMF from CSE to the aqueous phase. sephadex LH-20 enabled the separation and recovery of approximately 94.88% of 5-HMF from the aqueous phase.The coefficient of variation (CV) was 8.53% across three independent experiments. Two-way ANOVA indicated that although minor differences existed among different cigarette samples (P < 0.01), the elution profile of 5-HMF was highly consistent (tube number factor: P < 0.0001), accounting for 97.04% of the total variation, confirming the good reproducibility of the method. Based on the content calculation, this method achieved the separation of approximately 89.55% of 5-HMF from CSE, while the traditional component nicotine in cigarette smoke did not interfere with the separation and preparation of 5-HMF. Conclusion: This study realized the simple, rapid, efficient and stable separation and preparation of 5-HMF in cigarette smoke, which not only provided material and technical guarantee for the subsequent systematic study of the toxic effects of important components of cigarette smoke, but also provided methods and ideas for the separation and preparation of other components in the complex matrix of cigarette smoke.

Abstract:
Objective: To investigate the incidence and radiographic characteristics of mandibular deviation in patients with unilateral anterior disc displacement without reduction (anterior disc displacement without reduction，ADDWoR) of the temporomandibular joint, and to analyze the related factors influencing mandibular deviation. Methods: This retrospective study enrolled 210 patients (210 affected sides) with unilateral anterior disc displacement without reduction (ADDWoR) who visited the Department of Oral and Maxillofacial Surgery, Affiliated Stomatological Hospital of Nanjing Medical University between April 2020 and December 2023. Cone-beam computed tomography (CBCT) was used to analyze mandibular morphology and positional characteristics, while magnetic resonance imaging (MRI) assessed disc features. Multivariate logistic regression analysis was employed to identify factors associated with mandibular deviation. Results: Among the 210 patients, 104 were assigned to the deviation group (mean age 27.8±17.5 years) and 106 to the control group (mean age 34.0±19.2 years). The deviation group demonstrated significantly reduced ramus height and body length on the affected side compared to the unaffected side, with the entire mandible exhibiting posterior-superior rotation toward the affected side. This rotation pattern manifested as increased anterior joint space on the affected side, increased posterior/lateral/superior spaces on the unaffected side, while showing decreased posterior/lateral spaces on the affected side and reduced anterior space on the unaffected side. The articular disc in the deviation group was shorter in length and positioned farther from the condylar apex. In adolescent patients with deviation, besides mandibular morphological and positional changes, significant alterations in disc position were observed, whereas adult patients showed no remarkable changes in disc morphology or position. Multivariate logistic regression analysis revealed that mandibular positional parameters (including the ratio of anterior to posterior space on the affected side, lateral space on the affected side, the ratio of anterior to posterior space on the unaffected side, and superior space on the unaffected side) and mandibular morphological characteristics (ramus height discrepancy and mandibular body length discrepancy) were independent influencing factors for mandibular deviation (P < 0.05). Conclusion: The mandibular deviation associated with unilateral ADDWoR is closely related to changes in mandibular morphology and position. Sagittal shortening of the affected side and posterior-superior rotation of the entire mandible toward the affected side may be the primary contributing factors to mandibular deviation. Adolescent patients with ADDWoR are more prone to significant alterations in mandibular morphology, positional relationship, and disc status.

Abstract:
Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease characterized by synovitis and progressive joint destruction, leading to a high disability rate and complex complications that severely compromise patients' quality of life. Although traditional diagnosis and treatment have been shown to significantly enhance patient prognosis, challenges such as the difficulty of early diagnosis, substantial individual variability in treatment response, and the high prevalence of complications, including cardiovascular diseases and interstitial lung disease, continue to be focal points in clinical practice. Recent rapid advancements in artificial intelligence (AI) and machine learning (ML) technologies offer novel opportunities to overcome these bottlenecks in RA management. By deeply mining RA multimodal medical data, such as patient imaging, genomics, and electronic health records, ML models have shown potential advantages in early diagnosis, stratified management of treatment response, and modeling of complication risk, such as early warning of cardiovascular events. However, barriers such as data heterogeneity, limited model interpretability, and challenges in clinical translation hinder widespread adoption. This paper systematically reviews the latest research progress in applying ML to RA diagnosis and treatment, aiming to provide a theoretical foundation and practical reference for realizing ML-driven precision medicine in RA.

Abstract:
Abstract: To explore the effect of high-fat diet on delayed pleural effusion after single-port video-assisted thoracoscopic lung surgery.. Methods:?A retrospective analysis was conducted on the clinical data of 571 patients who underwent single-port video-assisted thoracoscopic lung surgery at the Department of Thoracic Surgery, Nanjing Medical University Affiliated Brain Hospital from December 2021 to June 2023. Patients were divided into high-fat diet group and non-high-fat diet according to a high-fat diet was adopted postoperatively. Propensity score matching analysis was used to match the two groups of patients with a ratio of 1:1, and then the incidence of delayed pleural effusion and other postoperative complications was compared between the matched groups. Results: Before matching, the high-fat diet group included 166 patients, with 45 males and 121 females, and a median age of 56.0 (49.0–66.0) years. The control group included 405 patients, with 164 males and 241 females, and a median age of 57.0 (48.0–67.0) years. After propensity score matching, each group included 130 patients. The high-fat diet group showed significantly higher incidences of delayed pleural effusion (OR=1.080, 95% CI=1.013–1.152, P=0.019), postoperative cough (OR=1.203, 95% CI=1.091–1.326, P=0.001), and postoperative chest tightness (OR=1.166, 95% CI=1.038–1.311, P=0.010) compared to the non-high-fat diet group, with statistically significant differences. Conclusion: A high-fat diet after single-port thoracoscopic lung surgery can significantly increase the incidence of delayed pleural effusion.

Abstract:
Objective: Intestinal fibrosis in Crohn's disease (CD) remains a clinical challenge with incompletely understood molecular mechanisms. This study systematically investigated the regulatory role and mechanism of IFN-γ in CD-associated intestinal fibrosis. Methods: Primary intestinal fibroblasts isolated from CD patients were treated with various cytokines in vitro. Amphiregulin (Areg) gene expression was assessed by RT-PCR. Based on preliminary results, fibroblasts were treated with 20 ng/mL IFN-γ for 48 h for RNA sequencing (RNA-seq). Protein-protein interaction (PPI) networks were constructed using the STRING database. Myofibroblast markers (α-SMA, Ki67) were detected by immunofluorescence to evaluate IFN-γ's effects on fibroblast activation and proliferation. Results: Key findings include: 1) Areg significantly promoted fibroblast activation, proliferation, and collagen synthesis; 2) IFN-γ markedly suppressed Areg expression and downregulated fibrosis-related genes (α-SMA, Col1a1, Col6a1); 3) IFN-γ reduced fibroblast proliferation (decreased Ki67+ cells) and activation (reduced α-SMA expression); 4) Transcriptomic analysis revealed significant enrichment of IFN-γ-regulated genes in ECM remodeling pathways, with PPI network identifying Src as a central node potentially mediating IFN-γ's anti-fibrotic effects. Conclusion: This study is the first to demonstrate that IFN-γ exerts anti-fibrotic effects by inhibiting the SRC/AREG signaling axis. We confirmed Areg as a key pro-fibrotic mediator, revealed IFN-γ's transcriptional suppression of Areg, and identified Src as a critical downstream effector of IFN-γ. These findings provide a theoretical foundation for developing novel anti-fibrotic strategies targeting the IFN-γ/SRC/AREG pathway.

Abstract:
Objective: To produce broad-spectrum nanobodies (Nbs) targeting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its variants, and establish a strategy for producing Nbs broad-spectrum neutralizing the virus and its various variants. Methods: Alpacas were immunized with the receptor-binding domain (RBD) of the SARS-CoV-2 wild-type strain (WT-RBD) to construct a nanobody phage library, and the library was screened by biopanning and ELISA with the RBD of the Delta variant (Delta-RBD) to select nanobodies. The selected nanobodies were expressed and purified using the Pichia pastoris system, and their properties and functions characterized by ELISA, biolayer interferometry, pseudovirus neutralization experiments, and molecular modeling and docking. Results: The four nanobodies obtained not only have high affinity for WT-RBD, but can also effectively neutralize Delta-RBD and the RBD of the Omicron variant (Omicron-RBD). Nb34, Nb42, and Nb45 show strong binding ability to the RBD of Delta-RBD and Omicron variants, meanwhile Nb45 can effectively neutralize the pseudovirus of Omicron variants. We also found that the mechanism of these nanobodies for neutralizing SARS-CoV-2 and its variants may be related to interfering with the conserved sites on these RBD. Conclusion: The four nanobodies obtained have great potential for prevention and treatment of SARS-CoV-2 and its variants, and the strategy established in this study can also be widely used for the preparation of nanobodies broad-spectrum neutralizing viruses and their various variants.

Abstract:
Objective: To investigate the biological functions and molecular regulatory mechanisms of kinesin family member 11 (KIF11) in colorectal cancer (CRC). Methods: The expression of KIF11 in CRC was examined by quantitative real-time PCR (qRT-PCR) techniques and publicSdatabases. CCK8 assay, colony formation assay, EDU assay, and transwell assay demonstrated the function of KIF11 in CRC progression, and Western blot(WB), RIP-qPCR, MeRIP-qPCR, and RNA stability assays elucidated the molecular mechanism of N6-methyladenosine(m6A)modification for KIF11.RNA sequencing (RNA-seq) and correlation analysis were used to examine the downstream mechanism of KIF11 regulation. Results: The results indicated that KIF11 was highly expressed in CRC and promoted CRC proliferation and migration. Mechanistically, METTL3/IGF2BP2 affected KIF11 mRNA stability and positively regulated KIF11 expression in an m6A-dependent way. Meanwhile, By means of the PROM1/PI3K/AKT pathway, KIF11 facilitated the progression of CRC. Conclusions: The m6A modification of KIF11 by METTL3/IGF2BP2 contributes to CRC progression via the PI3K/AKT signaling pathway, and it may function as a potential prognostic biomarker and therapeutic target for CRC.

Abstract:
Abstract: Objective: To investigate the clinical, imaging, and pathological characteristics, diagnosis, treatment, and prognosis of pancreatic acinar cell carcinoma (ACC). Methods: A retrospective analysis was conducted on clinical data of patients with pathologically confirmed ACC admitted to our institution from April 2015 to December 2024. The clinical manifestations, imaging and pathological features, diagnosis, treatment, and prognosis were summarized. Results: A total of 23 ACC patients were enrolled, including 15 males, with a mean age of 62 years. The most common presenting symptom was abdominal pain (13 cases), followed by jaundice, abdominal distension, and back pain. Tumors were located in the pancreatic head (15 cases), pancreatic body/tail (7 cases), and diffusely involved the entire pancreas (1 case). The mean tumor diameter was 54 mm. Tumors presented as solid (8 cases, 44.4%), solid with necrosis (5 cases, 27.8%), or cystic-solid (5 cases, 27.8%). Surgical resection was performed in 22 cases, while one patient underwent endoscopic ultrasound-guided biopsy due to metastasis to the №16 lymph node group and received comprehensive therapy. Pathologically, 21 cases were pure ACC, one case was mixed with ductal adenocarcinoma, and one case was mixed with neuroendocrine tumor. Lymph node metastasis was observed in 10 cases, and neurovascular invasion was present in 20 cases. R0 resection was achieved in 19 cases. Postoperative adjuvant chemotherapy was administered to 15 patients, with regimens including nab-paclitaxel plus gemcitabine (AG), gemcitabine plus oxaliplatin (Gemox), tegafur-gimeracil-oteracil potassium plus oxaliplatin (SOX), gemcitabine plus capecitabine (Gemcap), paclitaxel plus cisplatin (TP), and FOLFIRINOX. Among 21 patients with effective follow-up, the median overall survival was 26 months, and the median recurrence-free survival was 15 months. The 1-year and 3-year survival rates were 90.5% and 44.4%, respectively. The most common sites of initial recurrence were the liver (7 cases) and retroperitoneal lymph nodes (5 cases), followed by bone, lung, mesenteric lymph nodes, and local recurrence. Conclusion: Pancreatic acinar cell carcinoma is a rare malignant tumor characterized mainly by abdominal pain, often presenting as a solid mass with aggressive features such as frequent neurovascular invasion and lymph node metastasis. Surgical resection combined with adjuvant chemotherapy is the main treatment approach. Postoperative surveillance should focus on the liver and retroperitoneal lymph nodes for early detection of recurrence and metastasis.

Abstract:
Objective: To evaluate the efficacy and safety of gastroscopic biopsy forceps repositioning technique in peritoneal dialysis (PD) catheter drift. Methods: A retrospective analysis was conducted on clinical characteristics of PD catheter drift patients in the First Affiliated of Nanjing Medical University from January 2014 to December 2024. The technical success rate, procedure durations, cost, and complication rate were compared between conservative treatment, gastroscopic biopsy forceps repositioning and surgery repositioning. Results: Patients with catheter drift initially received conservative treatment, which achieved a success rate of 11.76% (2 out of 17). One patient requested laparoscopic repositioning, which was 100% successful (1 out of 1) at a cost of 3,000 yuan. The remaining 14 patients underwent gastroscopic biopsy forceps repositioning, with a success rate of 85.71% (12 out of 14). The procedure time for this method was 24.00 ± 6.65 minutes, and the cost was 130 yuan. The two patients who failed gastroscopic biopsy forceps repositioning had a long history of catheters placement over two years. They subsequently underwent successful open surgical repositioning, with a procedure time of 60 minutes and a cost of 400 yuan. No severe complications occurred in any of the cases, and all patients resumed dialysis function within 24 hours postoperatively. Conclusion: Gastroscopic biopsy forceps repositioning technique is a safe, cost-effective, and minimally invasive technique for PD catheter drift, with no radiation exposure.

Abstract:
Objective: To explore the influence of 18F-FDG activity on PET/CT image quality and establish a PET image quality restoration method to achieve radiation protection for patients. Methods: This study proposed a global feature recognition low-activity PET image quality restoration deep learning network model, (i.e., SwinUNetR-GAN) based on Swin Transformer. 124 patients’ PET/CT images who underwent 18F-FDG PET/CT scanning in 2024 were randomly selected to explore the law of PET image quality degradation under different activities of 18F-FDG, and the low-activity PET images’ quality restoration are achieved based on the SwinUNetR-GAN network. Results: As the activity of 18F-FDG decreases, the SUVmean and SUVmax in normal tissues and tumor lesions in the PET images show an increasing trend. When the activity of 18F-FDG is reduced to 10% of the current clinical activity, the SUVmean of the tumor lesion increases by about 1.1 times, while the SUVmax increases by about 2 times. In addition, the use of the SwinUNetR-GAN network can reduce the noise of 10% activity PET images, MAE decreases from 0.21 to 0.15, and Rdev decreases from 0.33 to about 0.25. Conclusion: This study clarifies the change law of quantitative parameters of normal tissues and tumor tissues in patient PET images under activity of 18F-FDG, and then, SwinUNetR-GAN network dedicated to low 18F-FDG activity PET image quality restoration was proposed, which could achieve the disease diagnosis performance of PET images while reducing the radiation dose deposited in patient.

Abstract:
Objective: To investigate the independent association between the triglyceride-glucose (TyG) index and subclinical left ventricular (LV) systolic dysfunction, and to analyze its impact on left ventricular global longitudinal strain (GLS) and myocardial work indices. Methods: A total of 103 patients admitted between August 2024 and February 2025 were enrolled. Clinical parameters, biochemical indicators, and echocardiographic data were collected, and the TyG index was calculated. GLS and LV myocardial work parameters (global work index, GWI; global constructive work, GCW; global wasted work, GWW; global work efficiency, GWE) were obtained using GE EchoPAC software. Multivariate logistic regression analysis was employed to assess the independent association between the TyG index and impaired LV function. Receiver operating characteristic (ROC) curves were plotted to evaluate the predictive efficacy of the TyG index for LV dysfunction, calculating the area under the curve (AUC), optimal cutoff value, sensitivity, and specificity. Results: The high-TyG group exhibited significantly higher prevalence rates of hypertension (67.31% vs. 43.14%), diabetes (42.31% vs. 7.84%), and dyslipidemia (34.62% vs. 3.92%) (all P < 0.05). Compared to the low-TyG group, the high-TyG group showed reduced absolute GLS (-17.60 ± 2.65 vs. -19.82 ± 2.12), lower GWI (1672.33 ± 308.58 vs. 1932.31 ± 280.26 mmHg%), and decreased GCW (1999.46 ± 324.11 vs. 2299.20 ± 323.32 mmHg%) (all P < 0.001). After adjusting for age, sex, body mass index (BMI), blood pressure, dyslipidemia, and other confounders, an elevated TyG index remained an independent risk factor for reduced GLS (OR = 2.982, 95% CI: 1.182-7.522, P = 0.021), reduced GWI (OR = 3.168, 95% CI: 1.302-7.706, P = 0.011), and diminished GCW (OR = 2.836, 95% CI: 1.250-7.309, P = 0.021). ROC analysis demonstrated the predictive efficacy of the TyG index for reduced GLS, GWI, and GCW, with AUC values of 0.725, 0.697, and 0.683, respectively. Conclusion: An elevated TyG index is independently associated with impaired LV global strain and myocardial work capacity, serving as a potential biomarker for subclinical LV dysfunction. This highlights its clinical utility in early risk assessment for metabolic cardiovascular diseases.

Abstract:
Objective To develop a predictive model for the lymph node ratio (LNR) in gastric cancer patients based on radiomics features extracted from preoperative imaging, and to construct a nomogram incorporating clinical factors to preoperatively predict LNR status. This model aims to assist in making more precise clinical decisions for gastric cancer treatment. Methods Clinical data of patients(n=380) who underwent radical gastrectomy at the First Affiliated Hospital of Nanjing Medical University between January 2014 and December 2018 were retrospectively collected. Patients with pathologically confirmed lymph node metastasis were selected. Preoperative imaging data were analyzed to extract radiomic features, followed by machine learning modeling. Three algorithms—Support Vector Machine (SVM), Random Forest (RF), and Logistic Regression (LR)—were evaluated. The RF model, which demonstrated the best performance based on the ROCcurve analysis, was selected for prediction. A nomogram was then developed using the RF score and clinically significant variables identified by multivariate logistic regression analysis. Results LNR was identified as an independent prognostic factor for patients undergoing gastric cancer resection. Three variables—RF score (p < 0.01), sex (p = 0.025), and clinical N stage (p < 0.01)—were included in the final nomogram model. The model’s performance was evaluated using ROC (The AUC value = 0.818)and decision curve analysis (DCA), both of which demonstrated good predictive ability. Conclusion The nomogram model based on radiomic and clinical information provides favorable predictive accuracy for preoperative LNR status in gastric cancer patients.

Abstract:
Objective: Using the Three-Dimensional Sampling Perfection with Application optimized Contrast using different flip angle Evolution (3D-SPACE) sequence combined with Compressed Sensing (CS) technology, the anatomical parameters of trapezoid ligament and conoid ligament (the two components of the coracoclavicular ligament) were quantitatively measured in a healthy population, such as the length, the attachment footprint width, and the position of attachment footprint center. Methods: Prospective collection of 64 patients without shoulder trauma who underwent shoulder joint MRI examination, the coronal T1WI 3D CS-SPACE sequence scans were performed on these patients. Two radiologists performed multiplanar reconstruction on these images, measuring the length of the trapezoid and conoid ligaments, the attachment footprint width on the clavicle, and the distance from the attachment footprint center to the outer edge of the clavicle on the oblique coronal image. The attachment footprint width on the coracoid process were measured on the oblique sagittal image. And the distance from the attachment footprint center of these two ligaments to the outer edge of the coracoid process and the size of the coracoid process was measured on the oblique axial image. When the measurement results of two physicians are consistent, take the average for statistical analysis. Grouping by gender, comparing the consistency between each parameter, and conducting correlation analysis between anatomical quantitative data of the coracoclavicular ligament and age and coracoid process size. Results: The length of the trapezoid ligament, the attachment footprint width on the clavicle and coracoid process of the trapezoid ligament, the distance from attachment footprint center of the trapezoid ligament to the outer edge of the clavicle and coracoid process, and the distance from attachment footprint center of the conoid ligament to the outer edge of the clavicle and coracoid process all showed statistical differences between males and females (P<0.05). There is no correlation between age and various anatomical parameters (P>0.05). Except for the length of the conoid ligament, the anatomical quantitative parameters of the trapezoid ligament and conoid ligament have varying degrees of correlation with the size of the coracoid process (P>0.05). Conclusion: The 3D CS-SPACE sequence can clearly display the anatomical structures of the trapezoid ligament and conoid ligament, and obtain quantitative anatomical parameters of them, providing a basis for individualized surgical treatment of patients with acromioclavicular joint injuries and reducing the occurrence of complications.

[Abstract] (21) [HTML] (0) [PDF 0.00 Byte] (0)

Abstract:
Objective: To investigate the role and molecular mechanism of RNA binding motif single stranded interacting protein 3 (RBMS3) in the proliferation of breast cancer and its molecular mechanism by regulating the stability of cyclin-dependent kinase inhibitor 1A (p21) at the post-transcriptional level. Methods: Colony formation and 5-ethynyl-2′-deoxyuridine (EdU) incorporation assays were used to evaluate cell proliferation ability in vitro. Flow cytometry was applied to analyze cell cycle distribution and apoptosis rate. Xenograft tumor model in nude mice was established to observe the effect of RBMS3 on tumor growth in vivo. The correlation between RBMS3 and p21 expression was detected by Western blot (WB), quantitative reverse transcription polymerase chain reaction (qRT-PCR), and immunohistochemistry (IHC). Furthermore, actinomycin D (Act D) assay was performed to verify the effect of RBMS3 on p21 mRNA stability. RNA immunoprecipitation (RIP) assay, dual-luciferase reporter assay, and rescue experiment were conducted to confirm the direct binding and functional interaction between RBMS3 and p21. Results: Overexpression of RBMS3 inhibited the proliferation of breast cancer cells and the growth of xenograft tumors in nude mice，induced G0/G1 phase cell cycle arrest, and promoted apoptosis. Conversely, knockdown of RBMS3 promoted breast cancer cell proliferation. Furthermore, RBMS3 expression was significantly positively correlated with p21. RBMS3 directly bound to AU-rich elements in the 3' untranslated region of p21 mRNA and enhanced the stability of p21 transcripts. Knockdown of p21 reversed the decrease in breast cancer cell proliferation induced by RBMS3 overexpression. Conclusion: RBMS3 upregulates p21 expression by directly binding to the AREs in the 3′-UTR of p21 and enhancing its mRNA stability, thereby inhibiting the proliferation of breast cancer cells. These findings suggest that RBMS3 may serve as a potential therapeutic target for breast cancer. Keywords: RBMS3, p21, mRNA stability, Breast cancer

[Abstract] (35) [HTML] (0) [PDF 0.00 Byte] (0)

Abstract:
Neutrophil extracellular traps (NETs), a reticular structure composed of DNA fibers, histones, and antibacterial proteins released by neutrophils, can trap and eliminate foreign pathogens and play a significant role in the initiation and development of tumors. The formation and release of NETs are regulated by various factors from the tumor microenvironment, including signaling molecules released by tumor cells, inflammatory cytokines, oxidative stress, and angiogenesis. In addition, NETs interact with immune cells in the tumor microenvironment, collectively shaping the immune characteristics of the tumor microenvironment and participating in critical biological processes such as metabolic regulation of tumor cells, tumor metastasis, tumor-related thrombosis, and tumor angiogenesis, all of which impact tumor progression and patient prognosis. This review focuses on the multiple mechanisms of NETs in tumor progression, explores the mechanisms of NETs in regulating tumor cell proliferation and metastasis, altering tumor microenvironment, affecting tumor angiogenesis, immune escape, and the potential application prospect of NETs as biomarkers for diagnosis and prognosis, which reveal the significant role of NETs in tumor biology and provide a theoretical foundation for future research and clinical application.

Abstract:
Non-alcoholic fatty liver disease (NAFLD) is currently the most prevalent chronic liver disease worldwide, posing a significant threat to human health; however, its pathogenesis remains incompletely understood. Research on regulatory cell death has opened new avenues for disease treatment. Among these, ferroptosis is a form of iron-dependent non-apoptotic cell death, which can be triggered by disturbances in iron metabolism, oxidative stress, and the accumulation of lipid peroxides. Given the liver's critical role in iron storage and lipid metabolism, recent studies have established a close association between ferroptosis and NAFLD. Abnormal lipid accumulation within cells can lead to redox imbalance, which may be a key factor contributing to lipid metabolism disorders. Consequently, inhibiting ferroptosis has emerged as a potential therapeutic strategy for NAFLD. Glutathione peroxidase 4 (GPX4) is a pivotal regulatory protein in ferroptosis, capable of binding to reduced glutathione (GSH) to degrade reactive oxygen species (ROS) and hydrogen peroxide (H2O2), thereby mitigating lipid peroxidation damage. Current research indicates that active components from traditional Chinese medicines, such as Astragalus, green tea, and Coptis, can modulate GPX4 through multiple targets, thereby influencing NAFLD. This review explores the mechanisms by which GPX4 operates within the ferroptosis pathway and identifies herbal extracts that may offer therapeutic benefits for NAFLD through GPX4 regulation.

Abstract:
Objective: Alzheimer’s disease (AD) is a progressive and irreversible neurodegenerative disorder, with patients often exhibiting social withdrawal at an early stage. Its primary pathological hallmarks include abnormal β-amyloid (Aβ) deposition, glial hyperactivation, synaptic impairment, and myelin dysfunction. Recently, the enriched environment (EE), a non-pharmacological intervention, has garnered attention for its potential to enhance neuroplasticity. However, research on the effects of EE on social behavior and related neuropathological changes in the early stages of AD remains insufficient. This study utilized the 5×FAD mouse model to systematically investigate the impact of EE on early pathological progression in AD, providing new evidence to support the application of EE in the prevention and treatment of AD. Methods: Two-month-old 5×FAD mice were randomly assigned to a standard environment (SE) group or an EE group (5 mice per cage) and maintained in their respective housing conditions for 4 weeks. Behavioral tests, including the Y-maze, open field, elevated plus maze, and three-chamber social interaction assays, were conducted. Histopathological analyses of the medial prefrontal cortex (mPFC) were performed to evaluate neuropathological changes. Results: EE did not affect short-term spatial memory or anxiety-like behaviors in 5×FAD mice but significantly enhanced their social interaction capabilities. Pathologically, 5×FAD mice exhibited marked Aβ deposition and glial activation in the mPFC. Compared to the SE group, EE mice showed significantly reduced Aβ accumulation and glial activation in the mPFC. Furthermore, EE improved myelin structural integrity in this region, while no significant effects were observed on synaptic proteins, synaptic ultrastructure, or neuronal survival. Conclusion: This study demonstrates that EE effectively mitigates AD-related pathology in 5×FAD mice and alleviates social behavioral deficits, highlighting its potential for addressing AD-associated social dysfunction. These findings suggest that environmental interventions may exert neuroprotective effects by modulating neuroinflammation, reducing Aβ deposition, and preserving myelin homeostasis during AD progression.Keywords: Enriched Physical Environment; Social Behavioral Deficits; Medial Prefrontal Cortex

Abstract:
Objective: This study aims to explore the safety and efficacy of utilizing indocyanine green near-infrared (ICG-NIR) fluorescence imaging to guide lymph node (LN) dissection during Da Vinci robotic gastrectomy (RG). Materials and methods: The patients who underwent RG at the General Surgery Department of Affiliated Hospital of Nanjing University of Chinese Medicine from January 2021 to January 2024 were retrospectively analyzed. Among them, 60 patients underwent ICG fluorescence navigation-guided lymphadenectomy (ICG group), while 117 received conventional LN dissection (non-ICG group). Propensity score matching (1:1) was performed to balance baseline characteristics. The number of retrieved LNs, surgical outcomes, postoperative complications, hospital stay, and recovery data were compared between two groups. Results: After matching, each group comprised 60 patients with comparable baseline characteristics, including age, sex, body mass index, nutritional risk screening scores, tumor diameter, tumor location, differentiation, vascular invasion, and Lauren type(p>0.05). All patients completed D2 lymphadenectomy, and there were no fluorescent LNs remaining after surgery. The ICG group had a significantly higher mean number of retrieved LNs (33.73±12.66) compared to the non-ICG group (26.15±6.31, p<0.05). Nevertheless, there was no significant difference in the number of positive LNs detected by postoperative pathology between two groups (4.67±7.83 vs 3.08±5.08, p>0.05). The ICG group demonstrated superior LN retrieval in both D1 and D2 regions (p<0.05), particularly at stations 3, 4d, 6, 7, 8a, and 12a. No significant differences were found in operative time, intraoperative blood loss, postoperative hospital stay, complication rates, or postoperative inflammatory indicators on day 3 (including c-reactive protein, white blood cell, albumin, and aspartate aminotransferase to alanine aminotransferase ratios) (p>0.05). A statistically significant difference in postoperative ventilation time was observed between the two groups (p<0.05), the ventilation time in the ICG group was found to be superior to the non-ICG group. Conclusion: ICG-NIR fluorescence imaging significantly improves the precision and completeness of LN dissection in RG without compromising perioperative safety. These findings provide preliminary evidence supporting the standardized application of this technique in robotic gastric cancer surgery.

Abstract:
Objective: This study aimed to investigate the impact of obesity on left ventricular mechanical contraction synchrony parameters in patients with normal myocardial perfusion imaging. Methods: A retrospective analysis was conducted on patients who underwent CZT SPECT myocardial perfusion imaging at the First Affiliated Hospital of Nanjing Medical University from January 2023 to August 2024. 133 patients with normal MPI results and left ventricular ejection fraction were included. They were divided into three groups according to body mass index (BMI): 40 cases in the normal group (BMI≤23.9), 45 cases in the overweight group(24≤BMI≤27.9), and 48 cases in the obesity group (BMI≥28). The differences in left ventricular function parameters such as PBW, PSD, EDV, ESV, and LVEF among the three groups were analyzed, and the influence of BMI on these parameters was explored. Results: The PBW (22.00±4.24 vs 17.10±3.20, p<0.001; 26.13±5.74 vs 17.10±3.20, p<0.001) and PSD values (5.04±1.05vs3.74±0.68, p<0.001; 6.34±1.43vs3.74±0.68, p<0.001) in the overweight and obesity group were significantly higher than those in the normal group. The PBW (26.13± 5.74 vs 22.00±4.24, p<0.001) and PSD values (6.34±1.43 vs 5.04±1.05, p<0.001) in the obesity group were significantly higher than those of overweight, and the difference was statistically significant. Body mass index (BMI) was significantly positively correlated with PBW (r=0.446, p<0.001) and PSD (r=0.477, p<0.001) in overweight and obesity patients. Conclusion: Obese patients are more likely to develop LVMD, and the novel cadmium-zinc-telluride SPECT phase analysis can effectively evaluate LVMD in obese patients at an early stage. This has significant clinical guiding significance for the early detection of LVMD in obese patients and the implementation of intervention to reduce cardiovascular events.

Abstract:
The extracellular matrix (ECM) generates multiple bioactive fragments, termed matrikines, which play pivotal roles in ECM functions. Acetylated proline-glycine-proline (AcPGP) is a matrikine derived from collagen. By binding to the C-X-C chemokine receptor type 1 and 2, AcPGP exhibits complex biological effects such as inflammatory responses, vascular permeability, tissue repair and remodeling. In the lungs, the dys-regulation of AcPGP contributes to a variety of respiratory diseases, and serves not only as a biomarker for diagnosis and assessment but also as a potential therapeutic target. This article reviews the regulatory mechanisms, biological functions of AcPGP in the lungs, and its role in respiratory diseases such as chronic airway inflammation diseases, acute lung injury, and pulmonary fibrosis.

Abstract:
Objective: To investigate the predictive value of clinical characteristics combined with intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) parameters for early pregnancy outcomes in patients undergoing frozen-thawed embryo transfer (FET). Methods: This prospective study enrolled 70 infertile women who underwent in FET at our reproductive center between December 2023 and January 2025. All participants underwent standardized pelvic non-contrast MRI on the day of embryo transfer. Clinical and laboratory indicators, conventional MRI features, and IVIM-DWI parameters were collected. IVIM-DWI parameters (diffusion coefficient D, pseudodiffusion coefficient D*, and perfusion fraction f) were extracted using FireVoxel software, with histogram data generated via SPSS. Student’s t-test, Pearson’s chi-square test, or Fisher’s exact test were employed to compare differences in clinical characteristics, MRI features, and IVIM-DWI parameters between the successful pregnancy group (n=42) and the non-pregnancy group (n=28). The receiver operating characteristic (ROC) curve was utilized to assess the diagnostic value of each parameter, with the area under the curve (AUC) and DeLong test serving as evaluation metrics.Results: The successful pregnancy group exhibited a higher proportion of high-quality embryos compared to the non-pregnancy group [32 (76.2%) vs. 13 (46.4%%), P=0.011] The junctional zone Dmean was significantly higher in the successful pregnancy group [45.233 ± 7.930 vs. 41.223 ± 6.369, P=0.029]. ROC analysis revealed that embryo quality (high-grade embryos) predicted pregnancy success with an AUC of 0.65 (sensitivity 53.6%, specificity 73.2%), while junctional zone D*mean achieved an AUC of 0.68 (sensitivity 73.8%, specificity 67.9%). The combination of embryo quality and junctional zone D*mean demonstrated superior predictive efficacy (AUC=0.73, sensitivity 82.1%, specificity 60.0%). Conclusion: IVIM-DWI enables noninvasive assessment of microcirculatory perfusion characteristics of FET patients. Combining embryo quality with junctional zone D*mean enhances the prediction of early pregnancy outcomes.

Abstract:
Objective: This study focuses on pregnant women with gestational diabetes mellitus (GDM) combined with thrombocytopenia, aiming to analyze their characteristics and pregnancy outcomes and reveal the influencing factors of the main adverse pregnancy outcomes. Methods: Pregnant women with GDM combined with thrombocytopenia who delivered in the First Affiliated Hospital of Nanjing Medical University from January 2015 to December 2024 were systematically screened. Maternal characteristics, including baseline, previous medical history, prenatal laboratory examinations, as well as maternal and neonatal outcomes, were analyzed. Logistic regression analysis was employed to identify the factors influencing the main adverse pregnancy outcomes. Results: A total of 233 women with GDM combined with thrombocytopenia were screened, accounting for 3.8‰ of all pregnant women. The mean maternal age was 31.95 years. Among them, 51.5% had a history of abortion, and 30.5% had other co-morbidities. In terms of maternal pregnancy outcome, 56.7% of them underwent the cesarean section. Additionally, 38 women (16.3%) experienced premature rupture of membranes, 30 (12.9%) had postpartum hemorrhage, and 26 (11.2%) had preterm delivery. Regarding neonatal outcomes, 24 newborns (10.3%) were macrosomia, 13 (5.6%) had low birthweight, 12 (5.2%) experienced neonatal distress, 17 (7.3%) had hyperbilirubinemia, and a total of 43 (18.5%) neonates were transferred to NICU. The multivariate logistic regression analysis showed that co-morbidities (OR=4.71, P=0.014) and fasting blood glucose (OR=2.48, P=0.044) were independent risk factors for preterm delivery in pregnant women with diabetes and thrombocytopenia. Prenatal D-dimer (OR=1.25, P=0.005) and platelet levels (OR=0.98, P=0.012) were significantly correlated with the risk of postpartum hemorrhage. In addition, higher body mass index in late pregnancy (OR=1.22, P=0.039) and fasting blood glucose (OR=1.93, P=0.047) independently impacted the risk of macrosomia. Conclusion: Pregnant women with gestational diabetes mellitus combined with thrombocytopenia are at higher risk of adverse maternal and infant pregnancy outcomes such as postpartum hemorrhage, preterm delivery, and macrosomia. For such pregnant women, comprehensive measures such as health education, dietary adjustments, moderate exercise, and medication treatment should be actively taken during pregnancy to control blood glucose and correct thrombocytopenia. Doctors and midwives should choose the appropriate mode of delivery to improve maternal and infant outcomes.

Abstract:
Cancer-associated fibroblasts (CAFs) are mainly derived from quiescent normal fibroblasts, and partially originated from mesenchymal stem cells, epithelial cells and endothelial cells. As an important part of the tumor microenvironment (TME), CAFs play a key role in the metastatic process of breast cancer. In recent years, researchers have paid more attention to the biological properties of CAFs and their interactions with breast cancer cells, which promote breast cancer cell invasion and metastasis by secreting various cytokines and exosomal microRNA (miRNA), altering extracellular matrix compositions, regulating intercellular signaling, and remodeling the TME. Although a large number of studies have revealed the importance of CAFs in breast cancer metastasis, their specific mechanisms of action need to be further explored. In this paper, we will systematically review the latest research progress of CAFs in breast cancer metastasis, and explore the core mechanism and function of CAFs in it, with a view to providing new ideas for future research.

Abstract:
Early gastrointestinal cancer (EGC) has subtle early symptoms and low screening rates, which leads to most patients being diagnosed at advanced stages, resulting in poor prognoses. Therefore, early diagnosis and timely treatment are crucial for improving patient outcomes. In recent years, artificial intelligence (AI) technology has been able to enhance the detection rate and diagnostic accuracy of early lesions through high-precision image analysis and data processing, thereby achieving early discovery, early diagnosis, and early treatment to improve patient prognoses. However, AI also faces challenges such as insufficient training data, algorithm bias, and uneven development across regions, which need to be addressed in future advancements. This review aims to provide a comprehensive overview of the current applications of AI in the diagnosis and treatment of EGC, exploring its advantages, challenges, and future directions to offer valuable references for researchers and clinicians in related fields.

Abstract:
Lactate metabolism plays a central role in the metabolic reprogramming of tumors and is critically implicated in the progression, metastasis, and therapy resistance of pancreatic cancer. Beyond being a glycolytic byproduct, lactate functions as a key signaling molecule that regulates tumor proliferation, invasion, immune escape, and drug tolerance. Recent advances have identified lactate dehydrogenase A (LDHA) and monocarboxylate transporters (MCTs) as promising therapeutic targets in pancreatic cancer. Preclinical studies suggest that disrupting lactate metabolism can suppress tumor growth and remodel the immunosuppressive tumor microenvironment. Moreover, lactate-associated biomarkers show potential in enhancing the diagnosis and prognosis of pancreatic cancer. Despite these advances, current lactate-targeted therapies are limited by poor specificity, suboptimal safety, and pharmacological instability. This review outlines the mechanistic underpinnings of lactate metabolism in pancreatic cancer, highlights emerging therapeutic targets and strategies, and discusses the potential of integrating lactate-targeted approaches with immunotherapy to improve clinical outcomes.

Abstract:
Objectives: Ovarian cancer (OC) ranks first among the female cancers worldwide. Numerous studies have explored the development and progression of OC at multiple genetic regulatory levels. However, relatively few studies have explored the impact of post-translational modifications (PTMs) on OC progression, which is essential for uncovering new therapeutic targets. We aimed to address this research gap. Methods: Firstly, we utilized multiple general PTM antibodies to compare gross PTM levels between normal ovarian and OC tissues from clinical females. After identifying lactylation as the PTM with the most significant differences, we selected representative samples for label-free mass spectrometry to identify specific lactylation sites. Next, we transfected A2780 (OC) cells with either wild-type (WT) or mutant (K192A[Q]) poly(ADP-ribose) polymerase 1 (PARP1) conjugated to enhanced green fluorescent protein (EGFP) with a Strep II peptide tag and assessed various cellular indexes related to cell proliferation, apoptosis, migration, and reactive oxygen species levels. Results: Pan-lactylation was significantly upregulated in clinical OC samples, with PARP1 lactylation at K192 being one of the most common modifications. The growth and migration of A2780 cells were markedly suppressed by overexpressing WT but not mutant PARP1. Overexpressing WT PARP1 significantly downregulated the phosphorylation of extracellular signal-regulated kinases 1/2 (ERK1/2). Conclusion: This study uncovered a novel PTM of PARP1 in OC, lactylation, and demonstrated that lactylation at K192 is crucial in regulating OC cell growth and migration via the ERK1/2 pathway. Further investigations are required to elucidate the broader functional implications of PARP1 lactylation and its therapeutic potential.

Abstract:
Objective：To analyze the related influencing factors of hepatic steatosis and explore the relationship between the arterial sclerosis index (AI) and non-alcoholic fatty liver disease (NAFLD). Methods：This study was a secondary analysis based on the public data of a cross-sectional study conducted at the Medical Health Examination Center of Kurosawa Memorial Hospital in Japan, involving 856 participants aged 24 to 84 years. The participants were divided into the NAFLD group (n=209) and the non-NAFLD group ( n=647) according to whether they had non-alcoholic fatty liver disease. The differences in clinical general data, laboratory indicators, AI values, and the detection rate of arterial sclerosis between the two groups were compared. Logistic regression analysis was used to evaluate the related factors of NAFLD, and a regression model was constructed to assess the correlation between AI and NAFLD. The receiver operating characteristic (ROC) curve was used to test the value of AI as an indicator for risk assessment of NAFLD. Results：There was a statistically significant difference in the gender composition ratio between the NAFLD group and the non-NAFLD group (P < 0.001), with more males in the NAFLD group. Compared with the non-NAFLD group, the NAFLD group had higher levels of body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyl transferase (GGT), fasting blood glucose, uric acid, triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and arterial pulse wave velocity of brachial artery (baPWV) (P < 0.001), lower levels of high-density lipoprotein cholesterol (HDL-C) (P < 0.001), and less exercise habits (P = 0.001). The AI values and the detection rate of arterial sclerosis in the NAFLD group were higher than those in the non-NAFLD group (P < 0.001). Binary multivariate Logistic regression analysis showed that AI, BMI, AST, fasting blood glucose, and baPWV were positively correlated with NAFLD. After fully adjusting for confounding factors, binary multivariate Logistic regression analysis showed that AI was positively correlated with NAFLD (OR = 1.846, 95% CI=1.541 - 2.121, P < 0.001), and the population in the highest AI group showed a significantly higher tendency of NAFLD compared to the lowest group (OR = 6.169, 95% CI = 3.006 - 12.661, P < 0.001). In the generalized additive model, there is a direct linear relationship between AI and NAFLD (log-likelihood ratio test, P = 0.949). The area under the ROC curve of AI is 0.775 (95% CI=0.739 - 0.811, P < 0.001), which is higher than that of baPWV and traditional lipid indicators [baPWV (AUC = 0.616, 95% CI = 0.574 - 0.659, P < 0.001), TC (AUC = 0.576, 95% CI = 0.532 - 0.621, P = 0.001), TG (AUC = 0.735, 95% CI = 0.696 - 0.774, P < 0.001), LDL-C (AUC = 0.639, 95% CI = 0.597 - 0.681, P < 0.001)].Conclusion：AI, BMI, AST, fasting blood glucose, and baPWV are independent related factors for NAFLD. Although AI cannot directly serve as a causal indicator for NAFLD, its potential in risk assessment is worthy of attention, especially when combined with imaging examinations, which can help improve the early diagnosis rate of NAFLD.

Abstract:
Objective: This study aims to evaluate the predictive value of nailfold capillaroscopy (NVC) in the diagnosis of patients with connective tissue disease-associated pulmonary arterial hypertension (CTD-PAH). Methods: A retrospective analysis was conducted on One hundred and forty-seven patients with connective tissue disease (CTD) who were hospitalised in the Department of Rheumatology and Immunology of the First Affiliated Hospital with Nanjing Medical University and underwent nailfold video capillaroscopy from September 2022 to June 2024. According to whether they were combined with pulmonary arterial hypertension (PAH) or not, CTD patients were divided into two groups: CTD-PAH and CTD-nonPAH. Risk factors for PAH in CTD patients were screened by multifactorial logistic regression analysis. A Nomogram prediction model was constructed based on this multifactorial logistic regression analysis and the model performance was evaluated using the receiver operating characteristic (ROC) curve. Results: Among the CTD patients, 52 (35.4%) were included in the CTD-PAH group. The capillary length was longer in the CTD-PAH group than in the CTD-nonPAH group [202.0 (160.0, 272.0) vs. 262.0 (207.0, 308.0), P<0.05], and the pericapillary score was higher than that in the CTD-nonPAH group [1.90 ( 0.40, 2.80) vs. 2.40 (0.80, 3.92),P<0.05]. Logistic regression analysis showed that both long capillary length and high pericapillary score increased the risk of PAH occurrence [OR=1.300 (95% CI: 1.100-1.500), OR=1.268 (95% CI: 1.025-1.568)]. The area under the ROC curve of the Nomogram prediction model amounted to 0.6913 (95% CI:0.6046~0.7781, P<0.05). Conclusion: The findings suggest that nailfold capillary characteristics, including capillary length and pericapillary score, may serve as independent predictors of PAH in patients with connective tissue diseases. These results provide a new basis for early screening and individualized therapeutic strategies in CTD-PAH patients.

Abstract:
Objective: To investigate the value of neutrophil gelatinase-associated lipocalin (NGAL) and reticulocyte percentage (Ret%) in differentiating acute kidney injury (AKI) from chronic kidney disease (CKD). Methods: The study included 437 patients with nephropathy from the Department of Nephrology of the First Affiliated Hospital of Nanjing Medical University. The subjects were divided into AKI group (n = 140) and CKD group (n = 297). To control potential selection bias, propensity matching analysis of 19 variables was used to compare the urine/serum NGAL (u/sNGAL) and Ret% between the two groups. According to the stratification of renal function, the differentiation ability of u/sNGAL and Ret% in AKI and CKD was compared. Results: The product of u/sNGAL and Ret% (u/sNGAL ×Ret%) in AKI group was significantly higher than that in CKD group (1.74 (0.79- 4.16) vs 0.28 (0.15- 0.55), P < 0.001). Propensiy-matched analysis included 46 patients in each group. In matched patients with AKI and CKD, Ret%, u/s NGAL, and u/s NGAL×Ret% were significantly increased in the AKI group (1.75 (1.26- 2.53) vs 1.37 (1.16- 1.83)). 0.64 (0.33- 1.52) vs 0.31 (0.13- 0.76) and 1.27 (0.59- 3.31) vs 0.46 (0.25- 1.53)) . In all patients (n = 437), the receiver operating characteristic (ROC) analysis showed that Ret%, u/sNGAL and u/sNGAL×Ret% could distinguish AKI from CKD (the area under the curve was 0.701, 0.847 and 0.868, respectively). After stratified by renal function, subgroup analysis showed that there were significant differences in u/sNGAL×Ret% between AKI group and CKD group (P < 0.01). In the subgroup analysis of patients with eGFR > 60mL/min/1.73m2, both u/sNGAL×Ret% and Ret% were able to differentiate AKI from CKD. However, in the subgroup analysis of patients with eGFR < 60mL/min/1.73m2, u/sNGAL×Ret% demonstrated superior performance in distinguishing AKI from CKD compared to Ret% (P < 0.05). Conclusion: u/sNGAL×Ret% can be used as an indicator for the differential diagnosis of AKI and CKD patients in the Department of Nephrology.

Keying Xu, Wei Zhang

Available online:September 12, 2025, DOI:

[Abstract] (32) [HTML] (0) [PDF 0.00 Byte] (0)

Abstract:
Objective: This study aimed to investigate the expression of fibroblast-derived Galectin-3 (LGALS3) in lung tissue of a silica (silicon dioxide, SiO?)-induced pulmonary fibrosis mouse model and its relationship with extracellular matrix (ECM) deposition, further elucidating the role of LGALS3 in the mechanism of silicosis fibrosis. Methods: A pulmonary fibrosis mouse model was established by silica exposure, and collagen deposition and structural changes in lung tissues were observed using Sirius Red staining and polarized light microscopy. Then, single-cell clustering analysis was performed to classify cells into 20 clusters, and differentially expressed genes upregulated in fibroblasts after 56 days of SiO? treatment were identified. Gene Ontology enrichment analysis using Metascape was conducted to identify genes associated with ECM binding. In vitro, human lung fibroblasts (HPF-a) and mouse lung fibroblasts (MLg) were stimulated with transforming growth factor-β1 (TGF-β1), and the expression levels of LGALS3 and its deposition on the ECM were detected by Western Blot and immunofluorescence staining. Results: Single-cell clustering analysis showed a significant increase in fibroblast numbers after 56 days of SiO? treatment, with the top ten upregulated genes identified as Ccl6, Lyz2, Ftl1, Spp1, Lgals3, Cxcl2, Fth1, Psap, S100a9, and Ctss. GO enrichment analysis indicated that these genes were closely associated with ECM binding, with Ctss, Lgals3, and Spp1 being the core related genes. Dot plots and violin plots demonstrated that the expression level of Lgals3 was significantly higher in the SiO? 56-day group compared to the control group. Sirius Red staining and polarized light microscopy revealed significantly increased collagen deposition and dense structure in the lung tissues of the SiO?-exposed group, exhibiting typical pathological features of pulmonary fibrosis. Western Blot results showed that LGALS3 expression in HPF-a cells exhibited a time-dependent increase after TGF-β1 stimulation, peaking at 12 hours (P < 0.05). Animal model validation confirmed that LGALS3 expression in lung tissues of the SiO?-exposed group was significantly higher than in the control group (P < 0.001), and immunofluorescence staining revealed enhanced co-localization signals of LGALS3 with the fibroblast marker Vimentin (P < 0.01). Furthermore, after seeding TGF-β1-stimulated MLg cells onto ECM, LGALS3 expression levels significantly increased (P < 0.05); even after cell removal, LGALS3 expression on the ECM remained higher than in the control group (P < 0.05). Conclusion: This study confirms that fibroblast-derived LGALS3 is significantly upregulated in lung tissues of a silica-induced pulmonary fibrosis mouse model and participates in ECM deposition. The expression of LGALS3 is regulated by TGF-β1 and shows persistent accumulation on the ECM. These findings reveal the critical role of LGALS3 in pulmonary fibrosis and provide new theoretical insights into the pathological mechanisms of silicosis and potential therapeutic targets.

Abstract:
Objective: This study aimed to explore the potential causal relationship between Helicobacter pylori (HP) infection and esophageal cancer (EC). We employed traditional two-sample Mendelian randomization (MR) methods, combined with Bayesian-weighted MR and linkage disequilibrium score regression (LDSC), and conducted a comprehensive meta-analysis on controversial findings to strengthen the evidence base. Methods: The analysis incorporated genome-wide association study (GWAS) data with HP infection as the exposure and EC as the outcome. We utilized a variety of MR methods, including inverse-variance weighted analysis, weighted median, MR-Egger, Simple mode, and Weighted mode to investigate the association between HP and EC. Additionally, Bayesian-weighted MR was introduced and results were corrected using the false discovery rate (FDR) to enhance precision. The study also involved outlier detection, heterogeneity testing, sensitivity analysis, pleiotropy assessment, and the removal of single nucleotide polymorphisms (SNPs) potentially affected by confounding factors. For results that were particularly contentious, a meta-analysis was performed to provide a broader perspective. Potential reverse causation was assessed using Steiger testing and reverse MR. Furthermore, LDSC was utilized to evaluate the genetic correlation between HP and EC. Results: The comprehensive analyses showed that both traditional two-sample MR and Bayesian-weighted MR after FDR correction indicated no statistically significant causal relationship between HP and EC（P>0.05）. No pleiotropy was evident（P>0.05）, and the robustness of the results was confirmed by the leave-one-out test. However, genetic correlation analyses of anti-Helicobacter pylori IgG serum positivity and Helicobacter pylori GroEL antibody levels suggested a potential genetic link with esophageal adenocarcinoma（P<0.05）. Conclusion: Despite the use of advanced statistical methodologies, the current evidence is insufficient to support a definitive causal relationship between HP and EC. This finding underscores the need for larger-scale GWAS data and more detailed subtype-specific analyses to further explore the relationship between these two conditions. Future research should include a broader range of populations and geographical areas to enhance the generalizability and applicability of findings, while also investigating the specific impacts of different HP strains and possible biological mechanisms, providing stronger scientific support for the prevention and treatment of esophageal cancer.

Abstract:
Objective: To construct a model for predicting pelvic lymph node metastasis in early-stage cervical squamous cell carcinoma. Method:The clinical data of patients in the Department of Gynecology, Affiliated Hospital of Southwest Medical University from January 2019 to October 2023 were retrospectively analyzed. Two models were obtained by univariate logistic analysis , forward and backward stepwise regression analysis. The Akaike Information Criterion (AIC), Continuous Net Reclassification Improvement Index (NRI) and Integrated Discriminant Improvement Index (IDI) were used to determine the optimal model .The model was converted into a nomogram, and its efficacy was evaluated by the area under the receiver operating characteristic curve(AUC), Hosmer-Lemeshow test, calibration curve and clinical decision curve (DCA). Bootstrap self-samples 1000 times for internal validation. Results: A total of 221 patients were enrolled. Forward and backward stepwise regression methods were used to establish model 1 and model 2. According to the results of AIC, serial NRI and IDI, model 2 was the optimal model (indicators: age, SCCA, CA125, and lymph node status on MRI). The AUC was 0.818 ; The Hosmer-Lemeshow test χ2=0.942, P=0.332, and the adjusted AUC was 0.800 ; DCA showed that when the threshold probability was 0.03-0.5, the clinical net benefit was higher. The AUC of the internal verification was 0.784. Conclusion:Models based on age, SCCA, CA125, and MRI lymph node status can help predict pelvic lymph node status for cervical cancer before surgery.

Abstract:
Objective: To investigate the effect and molecular mechanism of Nao Tan Qing (NTQ) on neural stem cell (NSC) proliferation in Alzheimer's disease (AD) mice. Methods: 5×FAD mice were randomly assigned to two groups, the AD group treated with ddH2O and AD+NTQ group orally administered with NTQ by gavage. Immunofluorescence staining, real-time quantitative PCR, and western blotting were used to evaluate neural stem cell proliferation in hippocampus. In vitro, neural stem cells were isolated and cultured with PBS, NTQ. Cell apoptosis and proliferation were assessed using the apoptosis and CCK-8 assays. Immunofluorescence staining was used to detect the number of SOX2+, BrdU+, and DCX+ cells. The mRNA and protein levels of Sox2 and Dcx were measured by real-time quantitative PCR and western blotting. The expression of key molecules CyclinD1, P27/Kip1 and Gata2 was detected by real-time fluorescence quantitative PCR and protein blotting; the expression level of Sox2 was detected by fluorescence quantitative PCR and protein blotting after the in vitro treatment of neural stem cells using CyclinD1-CDK inhibitor.Results: In the AD+NTQ group, the number of SOX2+ cells in brain significantly increased, with a marked elevation in Sox2 mRNA and protein levels compared with the AD group. In vitro, the diameter of neurospheres treatment with NTQ were significantly larged, along with the increased number of BrdU+, SOX2+, and DCX+ cells. Moreover, Sox2 and Dcx mRNA levels, as well as SOX2 protein level, were notably elevated. Mechanistically, the expression of GATA2 and its downstream molecule p27/Kip1 was decreased in the hippocampus of AD+NTQ mice, and the inhibitory effect on cyclinD1 was weakened in NSC proliferation. Addition of CyclinD1-CDK inhibitor attenuated the increase in Sox2, Dcx expression triggered by NTQ. Conclusion: NTQ maintains neural stem cell proliferation and alleviates cognitive deficits in AD mice by modulating the GATA2-p27/Kip1-cyclinD1 signaling pathway.

Abstract:
Objective: Acute pancreatitis (AP) is a common digestive emergency with high mortality in severe cases, making early risk identification crucial. This study aimed to investigate the association between first-day serum albumin (ALB) levels upon intensive care unit (ICU) admission and in-hospital mortality in patients with AP, and to explore its potential non-linear nature. Methods: This retrospective study analyzed data from 728 adult AP patients admitted to the ICU for the first time between 2008 and 2019, sourced from the MIMIC-IV database. First-day ICU ALB levels and relevant clinical data were extracted. Multivariable logistic regression models were used to assess the linear association between ALB and in-hospital mortality. Generalized additive models (GAM) and two-piecewise linear regression models were employed to explore non-linear relationships and identify inflection points. Results: After adjusting for multiple confounders, each 1 g/L increase in first-day ICU ALB was associated with a 27% reduction in in-hospital mortality risk (OR 0.73, 95% CI 0.59–0.92, P=0.007). GAM analysis further revealed a significant non-linear relationship between ALB and in-hospital mortality, with an inflection point at 28 g/L. When ALB was ≤ 28 g/L, each 1 g/L increase was associated with a 56% significant reduction in mortality risk (OR 0.44, 95% CI 0.26–0.73, P=0.001); however, this association was not statistically significant when ALB was > 28 g/L. Conclusion: First-day ICU serum albumin levels in patients with AP demonstrated a significant non-linear negative association with in-hospital mortality. An ALB level of 28 g/L was identified as an important clinical inflection point for distinguishing high-risk patients. Early monitoring and attention to ALB levels are crucial for risk stratification and clinical decision-making in AP patients.

Abstract:
Objective: To explore the role of circ_0003633 in osimertinib resistance of lung adenocarcinoma cells. Methods: By performing circRNA sequencing on osimertinib-resistant and sensitive cells, circ_0003633 was identified as significantly highly expressed in the resistant cells. The expression of circ_0003633 was knocked down in osimertinib-resistant cells, and its role in osimertinib-resistant lung adenocarcinoma cells was investigated through CCK8 assay, Transwell assay and colony formation assay. RNA Pull Down, transcriptome sequencing and bioinformatics analysis were used to screen downstream target genes and signaling pathways. Results: circ_0003633 is significantly highly expressed in osimertinib-resistant cells. Knockdown of circ_0003633 expression can significantly increase the sensitivity of osimertinib-resistant cells to osimertinib. circ_0003633 can bind to RNA-binding protein hnRNPA1 and regulate the downstream target gene ALDOC to exert biological functions. Conclusion: circ_0003633 is significantly highly expressed in osimertinib-resistant cells, binds to hnRNPA1 and regulates the downstream target gene ALDOC, activates the PI3K/AKT signaling pathway, promotes the resistance of lung adenocarcinoma cells to osimertinib, and can be used as a potential target for reversing drug resistance.

Abstract:
Spinal cord injury (SCI) is a severe central nervous system disorder with a high rate of disability and mortality. It is typically caused by traumatic vertebral burst fractures, with common causes including traffic accidents, falls from a height, and slips. After injury, patients often experience loss of motor and sensory functions, and may develop a variety of complications, such as respiratory dysfunction, cardiovascular dysfunction, neuropathic pain, muscle spasms, neurogenic bladder, and gastrointestinal dysfunction. These complications not only cause significant physical and psychological distress to patients but also severely impact their quality of life and prognosis. Early surgical intervention may salvage neural function, while rehabilitation training is also the essential therapeutic approach. The management of complications requires close collaboration among multidisciplinary teams. Effective preventive and therapeutic measures can significantly alleviate pain of patients and prolong survival. In recent years, with the deepening understanding of the pathophysiological mechanisms of SCI, clinical strategies for managing complications have been updated continuously. The application of new therapeutic methods and novel treatment strategies has brought hope for improving the quality of life of patients. This review summarizes the latest research progress on early complications of SCI, aiming to provide references for clinicians to optimize treatment plans and improve the quality of life for patients.

Abstract:
Human metapneumovirus (hMPV) belongs to the genus Metapneumovirus of the family Pneumoviridae. It was first discovered in the Netherlands in 2001. hMPV can cause repeated infections in infants, the elderly and immunocompromised population, and is one of the major pathogens causing severe acute lower respiratory tract infections. hMPV has spread across the world, becoming a serious public health and financial burden. Vaccination is supposed to be one of the most important means to prevent hMPV infection, transmission and reduce severeness of symptoms. Up to now, there is no approved hMPV preventive vaccine, and most clinical treatments are limited to symptomatic reduction. In recent years, significant progress has been made in the research on hMPV vaccines. Many vaccines have entered the clinical research stage, and there are numerous studies in the preclinical stage. This review will discuss the virological characteristics, epidemiological features and molecular mechanisms of hMPV infection of host cells, introduce the latest clinical development of hMPV vaccines, and present the preclinical research and development of hMPV vaccine from the perspective of different technical strategies, hoping to provide references to accelerate hMPV vaccine development.

[Abstract]Objective: To screen specimens with high qPCR positive rates based on HE histopathological characteristics for the rapid, accurate, and economical diagnosis of pulmonary tuberculosis. Methods: A retrospective analysis was conducted on the clinical data and CT findings of 189 patients with pulmonary granulomatous diseases. Formalin-fixed paraffin-embedded(FFPE) specimens were initially screened by Hematoxylin and Eosin (H&E) staining, followed by Ziehl-Neelsen (Z-N) staining and qPCR assay for further verification. Results: 1) Based on CT Findings, 189 specimens were divided into two groups: the peripheral nodular group predominantly showed hilar and mediastinal lymphadenopathy(87/149, 58.4%), lobulation sign (66/149, 44.3%), and spiculation sign (63/149, 42.3%); the central mass group mainly exhibited bronchial obstruction (31/40, 77.5%) and atelectasis (29/40, 72.5%). These findings were often indistinguishable from neoplastic lesions, leading to diagnostic delays.2) HE staining results from 95 confirmed pulmonary tuberculosis specimens revealed that the percentage of necrotic area≥25% (χ2 = 41.649, P = 0.000) and granuloma diameter≥8 mm (χ2 = 8.071, P = 0.004) were correlated with qPCR positivity. 3) Binary logistic regression analysis showed that the percentage of necrotic area and granuloma diameter in pulmonary tuberculosis were independent predictors of qPCR positivity(OR =1.324, 95%CI:1.202-1.460, P＜0.001; OR =0.265, 95%CI:0.164-0.429, P＜0.001). For FFPE specimens of pulmonary tuberculosis, the area under the curve (AUC), sensitivity, and specificity for measuring necrotic area percentage and granuloma diameter were 0.794/0.600, 78.2%/88.5%, and 78.9%/43.7%, respectively. Conclusion: When CT findings of peripheral nodules show hilar and mediastinal lymphadenopathy, lobulation sign, spiculation sign, they are more likely to delay diagnosis of granulomatous diseases such as pulmonary tuberculosis. The measurement of necrotic area and granuloma diameter can improve the sensitivity of qPCR detection. Preliminary screening with HE staining to select high-quality specimens for testing can enhance the accuracy of tuberculosis diagnosis.

Abstract:
【Abstract】 Objective: To explore the technical feasibility and clinical value of Uni-VATS (Uniportal Video-Assisted Thoracoscopic Surgery) in complex airway reconstruction. Methods: A 71-year-old patient presented with an isolated bronchial lesion in the posterior segment of the left lower lobe, with no significant invasion observed in either lung. After comprehensive risk assessment and perioperative preparation, the patient underwent a Uni-VATS thoracoscopic left lower lobe posterior segment sleeve resection combined with secondary carina reconstruction. Upon pathological confirmation of malignancy, a systematic lymphadenectomy was performed. To prevent postoperative complications, the anastomotic site was circumferentially wrapped using autologous tissue. Postoperative evaluation of therapeutic efficacy was conducted using bronchoscopy and imaging studies. Results: The surgical procedure was successfully completed with an operative time of 150 minutes and an intraoperative blood loss of 50 ml. Postoperative bronchoscopy showed good secondary carina reconstruction, and no anastomotic fistula occurred. The postoperative pathology confirmed negative margins, and the patient was extubated on the 5th day after the operation and discharged smoothly on the 6th day. This was confirmed as the first case of similar surgery in Jiangsu Province. Conclusion: Uni-VATS enables safe and efficient segmental sleeve resection and secondary carina reconstruction, demonstrating feasibility in complex airway reconstruction. Compared with conventional surgical approaches, Uni-VATS balances oncological radicality with lung function preservation, offering an innovative and minimally invasive solution for localized airway tumors. This case provides critical practical evidence for the extension of Uni-VATS to highly complex procedures, supporting its role in facilitating rapid patient recovery. Given these advantages, Uni-VATS holds clinical value for broader application and dissemination. Key words：Secondary carina reconstruction; Sleeve resection; Uniportal video-assisted thoracic surgery

Abstract:
[Abstract] Objective: To comparatively explore the value of left ventricular end-diastolic maximal wall thickness (MWT) and anatomical parameters of left ventricular outflow tract (LVOT) for evaluating myocardial fibrosis in hypertrophic cardiomyopathy (HCM) by cardiac magnetic resonance (CMR) and propose a prediction model. Methods: Seventy-seven HCM patients who underwent CMR examination were retrospectively analyzed. CMR data included partial anterior mitral leaflet length and total anterior mitral leaflet length. During end-diastole and end-systole, the diameter of LVOT and the thickness of basal anteroseptal were measured. Additionally, left ventricular end-diastolic MWT was collected and the percentage of late gadolinium enhancement (LGE%) was analyzed. LGE% was used to assess myocardial fibrosis. Seventy percent of the samples selected randomly by statistical software were assigned to the derivation cohort for establishing a prediction model of LGE% through univariable and multivariable analysis. The remaining thirty percent of the samples served as the internal validation cohort, and parameters of echocardiogram of all patients were used for external validation to assess the accuracy of the prediction model. Receiver operating characteristic curves were plotted, and the predictive efficacy of the prediction model was determined by calculating the area under the curve. The sensitivity and specificity of the prediction model were also evaluated. Results: In the derivation cohort, multivariable analysis indicated that MWT was an independent predictor of LGE% with the linear equation LGE% = -10.009 + 0.832 × MWT (r = 0.466, P < 0.001), while no anatomical parameters of LVOT were correlated with LGE%. In the validation cohort, there was no statistical difference between MWT measured by echocardiogram and MWT measured by CMR. Additionally, the predicted values from both internal and external validations showed no statistical difference from LGE%. The accuracy of predicting LGE%≥15% were 82.6% with a cutoff of 30mm for MWT measured by CMR and 81.7% with a cutoff of 25mm for MWT measured by echocardiogram respectively. Conclusion: When evaluating myocardial fibrosis in HCM, MWT has more predictive value than anatomical parameters of LVOT.

Abstract:
Objective：This study aimed to improve the L5 pedicle screw placement technique by proposing a novel entry point and validating its feasibility and accuracy compared with the traditional Magerl method.?Methods：Sixty patients requiring L5 pedicle screw fixation at the First Affiliated Hospital of Nanjing Medical University were enrolled and divided into two groups: the novel group (30 cases, 60 screws) and the traditional Magerl group (30 cases, 60 screws). Screw placement accuracy was evaluated using the Gertzbein and Robbins classification system. Outcomes including satisfactory screw placement rate, intraoperative radiation dose, operative time, blood loss, and postoperative nerve root injury symptoms were compared between the two groups.?Results：The novel group demonstrated a significantly higher satisfactory rate (95%) compared to the traditional group (80%，P?= 0.013). No significant intergroup differences were observed in operative time (183.93±40.00 vs. 193.33±55.05 min, P=0.452), intraoperative blood loss (334.09±218.43 vs. 318.52±253.87 mL, P=0.8), fluoroscopy exposure (88.72±42.52 vs. 106.09±43.10mGy·cm2, P=0.122). No neurological complications occurred in either group. Conclusion：The novel L5 entry point significantly improved screw placement accuracy (95% vs. 80%,?P?= 0.013) without increasing surgical risks, demonstrating potential for clinical application.

Abstract:
Abstract: Objective To investigate the regulatory effect of EZH2 on the FAK/F-actin/ROS pathway, and analyze its effects on the proliferation, invasion, and migration of colorectal cancer cells. Methods Twenty-four subcutaneous transplanted tumor models of nude mice were divided into the EZH2 NC group, EZH2 mimic group, EZH2 NC+ cytochalasin D group, and EZH2 mimic+ cytochalasin D group with 6 mice in each group. The tumor growth was observed after 14 days of incubation. After culture of human CRC cell lines SW480 and SW620 cells, SW480 cells were divided into 4 groups of a, b, c, and d by liposome transfection method: EZH2 NC was group a, EZH2 mimic was group b, EZH2 NC added cytochalasin D intervention was group c, and EZH2 mimic added cytochalasin D intervention was group d. SW620 cells were divided into groups e, f, g, and h, and the cell grouping treatment was the same as that of SW480 cells. Western blot assay was used to detect the expression of FAK/F-actin/ROS pathway-related proteins in SW480 cells of each group, and immunofluorescence staining was used to observe the expression and distribution of F-actin. Cell scratch assay was used to detect the migration ability of two kinds of cells, and Transwell migration assay was used to detect the migration ability of two kinds of cells. CCK-8 assay was used to detect the activity of the two cells. Results The tumor volume of the EZH2 mimic group was significantly larger than that of the EZH2 NC group (P<0.05), and the tumor volume intervened by cytochalasin D was significantly reduced compared with that before (P<0.05), and there was no significant difference between the two groups (P>0.05). The protein expression levels of EZH2, p-FAK, p-Paxillin, NOX2, NOX4, and p-JNK in the EZH2 mimic group were significantly higher than those in the EZH2 NC group (P<0.05), and the protein expression level of RUNX3 was slightly lower than that in the EZH2 NC group (P<0.05). The number of F-actin distributions, migration capacity, and cell viability were increased. After cytochalasin D intervention, the protein expression levels of EZH2, p-FAK, and p-Paxillin were not significantly different from before (P>0.05), the protein expression levels of NOX2, NOX4, and p-JNK were significantly lower than before (P<0.05), and the protein expression level of RUNX3 was significantly higher than before (P<0.05). There was no significant difference between the two groups (P>0.05), and the F-actin distribution number, migration ability, and cell viability were reduced, with no significant difference between the two groups (P>0.05). Conclusion EZH2 can promote the proliferation, invasion and metastasis of colorectal cancer cells by up-regulating FAK/F-actin/ROS pathway activity.

Abstract:
Objective: To investigate the distribution, drug resistance of pathogens and prognostic risk factors in patients with positive catheter culture, and to provide pathogenic basis and preventive measures for clinical catheter-related infection. Methods: The etiological data of patients with positive catheter culture in the First Affiliated Hospital of Nanjing Medical University from 2018 to 2023 were retrospectively analyzed, and the clinical data of the patients with the top three pathogens were collected to analyze the risk factors affecting the prognosis. Results: The overall positive rate of catheter culture was 14.7% (1240/8407). After removing the same pathogens isolated from the same patient, a total of 1096 strains of pathogens were isolated from 916 patients, 48.7% of which were gram-negative bacteria, mainly Klebsiella pneumoniae, Acinetobacter baumannii and Escherichia coli. Gram-positive bacteria accounted for 39.2%, mainly Staphylococcus aureus, Staphylococcus epidermidis and Enterococcus. The resistance rate of Klebsiella pneumoniae to most antibiotics was higher than that of Escherichia coli. The resistance rate of Acinetobacter baumannii to most cephalosporins and carbapenems was higher (>85.0%). The detection rates of methicillin-resistant Staphylococcus aureus and Staphylococcus epidermidis were 35.6% and 92.2%, respectively. No vancomycin and linezolid resistant Staphylococcus and Enterococcus were detected. Multivariate analysis showed that male, ≥65 years old, history of dialysis, combined catheter-associated bloodstream infection and tracheal intubation were independent risk factors for prognosis in patients with catheter-associated infection (P<0.05). Conclusion: The incidence of catheter-associated infection is high, which needs clinical attention. Continuous monitoring and analysis of etiological characteristics in the local area can provide theoretical basis for clinical empirical anti-infection treatment.

Abstract:
Objective: Comparison of the predictive performance of MELD 3.0, MELD-Na, and MELD scores in assessing the 3-month and 1-year survival prognosis of patients with decompensated cirrhosis. Methods: We conducted a retrospective analysis of clinical data from 438 patients diagnosed with decompensated cirrhosis who received either outpatient or inpatient care from January 2013 to December 2022. Based on their survival status at 3 months and 1 year, the patients were categorized into survival and death groups. The predictive value of MELD 3.0, MELD-Na, and MELD scores for 3-month and 1-year mortality was compared using receiver operating characteristic (ROC) curves, the area under the curve (AUC), calibration curves, net reclassification improvement (NRI), integrated discrimination improvement (IDI), and decision curve analysis (DCA). Results: At the 3-month and 1-year follow-up points, 15.53% and 26.26% of patients had died, respectively. The area under the curve (AUC) for predicting 3-month and 1-year mortality for the MELD 3.0, MELD-Na, and MELD scores were 0.859 (0.805-0.913), 0.857 (0.802-0.912), 0.856 (0.800-0.911) and 0.841 (0.796-0.886), 0.832 (0.785-0.880), 0.830 (0.782-0.878), respectively. However, the differences were not statistically significant (P >0.05). The MELD 3.0 score can increase the score range for 18.0% of patients with MELD-Na scores, and 21.5% of patients with MELD scores are reclassified into a higher score category. On the calibration curve, all three models showed similar trends between predicted and actual probabilities at both time points. In terms of predicting 3-month mortality, the NRI for MELD 3.0 compared to MELD was 0.240 (0.009-0.401), a statistically significant difference (P = 0.032). For predicting 1-year mortality, the NRI and IDI for MELD 3.0 compared to MELD were 0.201 (0.079-0.401) and 0.032 (0.006-0.057), respectively, both of which were statistically significant (P < 0.05). In subgroup analyses, including male and female patients, viral and non-viral causes, and Child-Pugh Class B and C patients, no significant statistical differences were observed among the three models (P > 0.05). Conclusion: Compared to MELD or MELD-Na, MELD 3.0 demonstrates improved predictive performance, making it more effective for precise risk stratification in patients with decompensated cirrhosis.

[Abstract] (78) [HTML] (0) [PDF 0.00 Byte] (0)

Abstract:
Background: This study was conduct to develop a predictive model for differentiating between benign and malignant Breast Imaging Reporting and Data System (BI-RADS) 4A, 4B breast lesions, which featured non-parallel and small on ultrasound. Methods: For this retrospective study, 327 patients were recruited in the First Affiliated Hospital of Nanjing Medical University from June 2020 to May 2024. Patients were divided into training set (N=229) and validation set (N=229) at the ratio of 7：3. Logistic regression analysis was used to identify risk factors and develop a predictive model to differentiate benign and malignant breast lesions. The effectiveness of the model was evaluated by the receiver operating characteristic (ROC) curve and the decision curve analysis (DCA). Results: The proportion of malignant tumors was 36.1% (118/327) in this study. With univariate and multivariate analyses, a predictive model compromised age, margin, elasticity assessment and US-BI-RADS was built and shown as a nomogram. The area under the ROC curve was 0.846 and 0.798 in the training and test cohort, respectively. DCA demonstrated that the model could achieve benefits for patients. Moreover, the study stratified the breast lesions into three risk groups according to the risk scores calculated by the nomogram. Patients were regarded as “high risk” with a risk score more than or equal to 0.7, and as “low risk” with a risk score less than or equal to 0.1. The proportion of malignancy was 8.8% and 82.1% in low- and high-risk group. Conclusion: The study established a predictive model based on clinical and ultrasound features. The model could effectively differentiate benign and malignant non-parallel and small BI-RADS 4A, 4B breast lesions. This model can distinguish different risks, with a lower probability (8.8%) of malignant breast lesions in the low-risk group and a higher probability (82.1%) in the high-risk group.

Abstract:
[Abstract] Objective: To investigate the relationship between serum programmed cell death factor 4 (PDCD4) levels and neurological deficits and prognosis in patients with acute ischemic stroke (AIS). Methods: A cohort of 110 AIS patients from the Department of Neurology, Affiliated Hospital 2 of Nantong University, admitted between June 2023 and March 2024, was retrospectively included as the study subjects. Based on the National Institutes of Health Stroke Scale (NIHSS) scores, patients were divided into a mild group (n=70) and a moderate to severe group (n=40). According to the modified Rankin Scale (mRS), patients were further divided into a good prognosis group (n=69) and a poor prognosis group (n=41). The demographic data (Age, Gender, history of diabetes, etc.) and clinical data (Neutrophil count, lymphocyte count, Neutrophil/lymphocyte ratio, etc.) of each group of patients were collected. Serum PDCD4 levels were measured using an Enzyme-linked immunosorbent assay (ELISA). The association between PDCD4 levels and NIHSS scores, mRS scores, and other inflammatory markers was analyzed in this study. Logistic regression analysis was used to infer the risk factors for moderate to severe neurological deficits and poor prognosis in AIS patients. Receiver operating characteristic (ROC) curves were used to evaluate the effectiveness of serum PDCD4 levels in predicting the degree of neurological deficit and prognosis of AIS patients. Results: In comparison to individuals with mild neurological deficits and good prognosis, those with moderate to severe neurological deficits and poor prognosis had considerably greater serum PDCD4 levels. PDCD4 levels showed a positive correlation with NIHSS scores, mRS scores, Hs-CRP, Procalcitonin, and Neutrophil/lymphocyte ratio. After controlling for confounding factors, PDCD4 remained an independent risk factor for acute ischemic stroke (AIS). Serum PDCD4 has a strong predictive value for neurological deficits and prognosis in individuals with AIS, according to ROC curve analysis. Conclusions: In AIS patients with moderate to severe neurological deficits and poor prognosis, serum PDCD4 levels are significantly elevated and can serve as an independent predictor of neurological deficits and prognosis.

Abstract:
Abstract: Objective: To investigate the efficacy and safety of CT-guided percutaneous liquid nitrogen cryoablation technique in the treatment of lung malignant tumors in the elderly. The focus is on analyzing the differences in the efficacy of this technique in different lesion types and treatment objectives (radical vs. palliative), as well as its impact on patients' quality of life and postoperative recovery. Methods: The clinical data of 56 elderly patients with lung malignant tumors who underwent CT-guided percutaneous liquid nitrogen cryoablation from January 2023 to December 2023 at the Second Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. The patients were ≥65 years old, including 44 males and 12 females, with a mean age of 76.4±8.3 years. They were divided into radical ablation group (49 cases) and palliative ablation group (7 cases) according to the purpose of treatment. All patients underwent detailed imaging examination and functional assessment before surgery, and the lesions were precisely localized under CT guidance using a cryoablation needle during the procedure. Postoperative follow-up was performed at 1, 3, and 6 months, respectively, to assess the ablation efficacy by the modified solid tumor efficacy evaluation criteria (mRECIST), and to record the intraoperative and postoperative complication rates, pain scores (VAS), changes in C-reactive protein (CRP), and quality of life scores (ECOG). Results: All 56 patients successfully completed the procedure with no serious intraoperative complications. Postoperatively, 16 cases (28.57%) developed pneumothorax, including 10 cases with mild pneumothorax (17.9%) and 6 cases with large pneumothorax (10.7%). All pneumothorax cases were treated conservatively or with chest tube drainage and recovered well. The postoperative pain scores were 4.5±1.2 on day 1, significantly decreased to 2.5±0.8 by 1 week, and further reduced to 1.3±0.5 at 1 month. CRP levels significantly increased to 45±10 mg/L on postoperative day 1, decreased to 20±8 mg/L at 1 week, and returned to near baseline levels (12±4 mg/L) at 1 month. Curative ablation group: The complete response (CR) rate at 1 month was 100%, 91.83% at 3 months, and 83.67% at 6 months, with a local recurrence rate of 16.33% (8/49). Palliative ablation group: The partial response (PR) rate at 1 month was 100%, decreased to 85.71% at 3 months, and further declined to 57.14% at 6 months. One patient in this group developed disease progression (PD) at 6 months. All patients showed improvement in quality of life, with ECOG scores decreasing from an average of 3.2±0.6 before surgery to 2.1±0.5 at 1 month and further improving to 1.3±0.4 at 6 months. Most patients were discharged within 3-5 days after the procedure, with a rapid recovery and no significant long-term decline in quality of life. Conclusion: CT-guided percutaneous liquid nitrogen cryoablation is a safe and effective minimally invasive treatment, especially for elderly lung cancer patients who cannot tolerate surgery. The technique has the advantages of less trauma, less pain, faster recovery, and significant short-term efficacy, especially in radical ablation with higher complete remission rate. Palliative ablation can effectively relieve symptoms and improve quality of life, but the long-term results may need to be further optimized in combination with other treatments. This study provides an important reference for the individualized treatment of elderly lung cancer patients and lays the foundation for the future application and development of cryoablation technology.

Abstract:
Objective: Construction and identification of an chronic antibody-mediated rejection model of renal graft in mice. Methods: Male 6-8 weeks old BALB/cH2d and C57BL/6H2b mice were used as experimental mice and randomly divided into following groups:①The syngeneic control group (SYN14D): no skin transplantation was performed，only C57BL/6H2b to C57BL/6H2b kidney transplantation was conducted，the transplanted kidney was removed 14 days later; ②T cellular-mediated rejection group (TCMR14D): no skin transplantation was performed，only BALB/cH2d to C57BL/6H2b kidney transplantation was conducted，the transplanted kidney was removed 14 days later; ③acute antibody-mediated rejection group (aABMR，BST5D+KT5D): full-thickness back skin transplantation was performed on C57BL/6 mice for 5 days (BALB/CH2d→C57BL/6H2b)，followed by BALB/cH2d to C57BL/6H2b kidney transplantation，the transplanted kidney was removed 5 days later; ④chronic antibody-mediated rejection group 1 (cABMR，TST2D+KT14D): tail skin transplantation was performed on C57BL/6 mice for 2 days(BALB/CH2d→C57BL/6H2b)， followed by BALB/cH2d to C57BL/6H2b kidney transplantation， the transplanted kidney was removed 14 days later; ⑤cABMR group 2 (TST3D+KT14D): tail skin transplantation was performed on C57BL/6 mice for 3 days(BALB/CH2d→C57BL/6H2b)， followed by BALB/cH2d to C57BL/6H2b kidney transplantation， the transplanted kidney was removed 14 days later; ⑥cABMR group 3 (TST4D+KT14D): tail skin transplantation was performed on C57BL/6 mice for 4 days(BALB/CH2d→C57BL/6H2b)， followed by BALB/cH2d to C57BL/6H2b kidney transplantation， the transplanted kidney was removed 14 days later. Pathological staining and Banff score were performed to diagnose the transplanted kidneys，survival curves were plotted，the levels of complement fragment C3d deposition，peripheral blood IgG class donor-specific antibody (DSA)，serum creatinine (Cr) and serum urea nitrogen (BUN) were detected in transplanted kidney tissues，the expression of CD3+T cells，CD19+B cells，F4/80 labelled macrophages，Ly6G labelled myeloid cells was detected. Results: The pathological injury of cABMR group 1 met the diagnostic criteria of ABMR，the postoperative survival rate was 80%，the expression of CD3+T cells was not obvious，so cABMR group 1 was subsequently selected as the model of cABMR for experimental demonstration. Compared with SYN14D，the C3d expression of cABMR was significantly enhanced，the average fluorescence intensity of peripheral blood IgG class DSA was significantly higher，peripheral blood serum Cr and BUN levels were significantly higher. Compared with aABMR，cABMR model of transplanted kidneys showed peritubular capillary haemorrhage and dilatation，single nucleus infiltration seen in the glomeruli，more typical tubular damage and brush border detachment in the tubules， higher Banff scores，significantly more positive areas of C3d expression，significantly higher mean fluorescence intensity of peripheral blood IgG class DSA，significantly higher peripheral blood serum Cr and BUN levels. Compared with aABMR，cABMR group renal interstitial and peritubular capillary CD19+B cells and CD3+T cells infiltration were not significant，renal interstitial F4/80 labelled macrophage and Ly6G labelled myeloid cell infiltration were more significant. Foxp3 and IL-10 expression was significantly reduced in cABMR model， infiltration of IL-1β，IL-6，TNF-α and CCL2 inflammatory cytokines was significantly increased in cABMR model. Conclusion: Our group constructed a cABMR model in which the survival cycle was prolonged，on the basis of which the effects of drug interventions on the prognosis of ABMR patients can be evaluated，which has high clinical application value.

Abstract:
[Abstract] Objective：To investigate the correlation between frailty status and disease severity in elderly patients with coronary artery syndrome (CAS) and analyze risk factors in this population. Methods：This analytical cross-sectional study included 187 elderly patients diagnosed with CAS at the First Affiliated Hospital of Nanjing Medical University from September 2023 to September 2024, who underwent coronary angiography and intervention. Participants were categorized into non-frail, pre-frail, and frail groups using the FRAIL Scale. Coronary lesion severity was assessed using the Gensini score, and cardiac structure/function was evaluated via echocardiography. A Gensini score >43 (defined by the tertile method) was classified as high. Risk factors were screened using univariate analysis and further analyzed via multivariate logistic regression. Restricted cubic splines were applied to test nonlinear relationships. Results : The cohort comprised 74 non-frailty, 72 pre-frailty, and 41 frailty cases. Pre-frailty and frailty groups had higher mean ages and increased proportions of NYHA class III cardiac function (P<0.05). Atrial fibrillation and low glomerular filtration rates were more prevalent in frailty and pre-frailty groups compared to non-frailty (P<0.05). High Gensini scores occurred more frequently in frailty (36.6%) and pre-frailty (33.3%) groups than in non-frailty (20.3%), though differences were not statistically significant (P>0.05). Left atrial diameter progressively increased across non-frailty (36 mm), pre-frailty (38 mm), and frailty (40 mm) groups (P<0.05). Left ventricular end-diastolic diameter was larger in pre-frailty (50 mm) versus non-frailty (47.5 mm, P<0.05). Segmental wall motion abnormalities were higher in frailty (24.4%) and pre-frailty (38.9%) groups than in non-frailty (17.6%, P<0.05). Logistic regression identified hypertension, diabetes, fasting glucose, and segmental wall motion abnormalities as positively correlated with high Gensini scores (all P<0.05), while BMI showed a negative correlation (OR=0.872, 95% CI: 0.775–0.980, P=0.021). Spearman analysis revealed a weak negative correlation between BMI and Gensini scores (R=-0.161, P=0.028). Restricted cubic splines indicated no significant nonlinear relationships between BMI and Gensini scores overall or within frailty subgroups (P>0.05). Conclusion :Frailty status was not significantly associated with coronary lesion severity in elderly patients with coronary syndrome. However, frailty and pre-frailty were linked to increased cardiac structural abnormalities and impaired contractile function.

Abstract:
As a common malignant tumor, the incidence and mortality rate of gastric cancer are still high in the world, among which the disease burden in China is significantly higher than the global average, and the mortality rate ranks third among malignant tumors in China. AFPGC is a special subtype of gastric cancer characterized by abnormally elevated serum AFP levels or positive AFP expression in tumor tissues detected by immunohistochemistry. The incidence of AFPGC in China accounts for approximately 2.3% to 4.6% of gastric cancer cases. Compared with conventional gastric cancer, AFPGC is more prone to distant metastasis, particularly liver metastasis, and has a poorer prognosis. Currently, there are no standardized treatment guidelines for AFPGC, and its management primarily relies on conventional gastric cancer treatment strategies. Research is ongoing to explore the differences between the occurrence and development of this tumor and general gastric cancer, as well as the related clinical features and efficacy of therapy. This article mainly reviews the biological features, clinicopathological characteristics and current treatment explorations of AFPGC in domestic and foreign research.

Abstract:
Prostate cancer is one of the most common malignant tumors in men. Prostate biopsy can directly obtain prostate tissue samples for pathological analysis to preoperatively diagnose or exclude prostate cancer. However, as an invasive examination method, it inevitably causes complications such as bleeding, infection, vagal reflex, and acute urinary retention. Therefore, reducing unnecessary biopsies and improving biopsy techniques are crucial. Currently, with the development of various imaging technologies and artificial intelligence, the techniques for guiding prostate biopsies are gradually improving. This article aims to elucidate the advantages and disadvantages of prostate biopsy techniques under different guidance methods and the research progress of new technologies.

Abstract:
Objective Early identification of coronary artery disease (CAD) is crucial for improving prognosis. This study investigated the relationship between an oxidative stress-lipid metabolism composite biomarker (Hpx·apoB) and CAD, and evaluated its value for clinical risk stratification. Methods The study utilized liquid chromatography-tandem mass spectrometry (LC-MS/MS) to quantify plasma Hpx levels in 107 CAHD patients and 33 controls without CAHD, while also gathering relevant clinical data. We analyzed the correlation between Hpx·apoB and CHD and developed a clinical predictive model. Predictive performance was assessed using receiver operating characteristic (ROC) curve analysis and net reclassification improvement (NRI). Results The HPX·apoB levels were markedly higher in the CAHD group compared to the control group (P<0.01). Significant increases in Hpx·apoB were observed in patients with acute myocardial infarction, acute coronary syndrome, and multivessel diseased group (all P<0.01). Multivariate analysis identified Hpx·apoB as an independent risk factor for CAHD (OR=2.554, 95% CI: 1.336-4.881, P<0.01). ROC analysis demonstrated: Standalone predictive AUC=0.667;Combined with CRP+LDL-C: ΔAUC=+0.106 (P<0.05), NRI=15.6% (P<0.05);Integrated with Framingham score: ΔAUC=+0.076 (P=0.139), NRI=27.0% (P<0.01);Integrated with SCORE model: ΔAUC=+0.142 (P=0.093), NRI=37.6% (P<0.001). Further subgroup analysis revealed that the predictive strength of HPX·apoB for CAHD was particularly pronounced in males, smokers, and individuals with renal impairment(P<0.05). Conclusion Hpx·apoB, as a composite biomarker reflecting oxidative stress and lipid metabolism, independently predicts CAD risk. Its combination with clinical risk scores significantly improves risk prediction performance.

Abstract:
Objective: Pseudomonas aeruginosa is a Gram-negative opportunistic pathogenic bacterium capable of causing various infectious diseases including pneumonia, urethritis, keratitis, and sepsis. The current misuse of antibiotics and the increasing annual isolation of multidrug-resistant (MDR) strains have posed significant challenges to clinical treatment. Recent studies highlight phage therapy as a promising therapeutic strategy. Our study aims to isolate and purify novel P. aeruginosa bacteriophages. Methods: Bacteriophages were isolated from campus lake water, followed by genome sequencing and biological characterization of purified phages. In vitro antibacterial assays including growth inhibition curves and biofilm eradication experiments were conducted. Results: A novel P. aeruginosa phage named PAPX was successfully isolated from campus pond water. Genomic analysis revealed 98% identity with Pseudomonas phage Epa12, classifying it within the Pbunavirus genus. Transmission electron microscopy demonstrated its myoviral morphology featuring an icosahedral head (～90 nm diameter) and a contractile tail (～50 nm length, 26 nm diameter). Biological characterization showed strong lytic activity against 17 of 24 clinical strains. In vitro experiments confirmed its ability to suppress bacterial growth during early proliferation phase and effectively eradicate P. aeruginosa biofilms. Conclusion: The successful isolation and characterization of phage PAPX, validated through biological profiling and in vitro assays, demonstrates its promising clinical potential for treating P. aeruginosa infections, particularly in combating antibiotic-resistant strains and biofilm-associated infections.

Abstract:
Objective: To explore the expression of β-galactoside-α2,3-sialyltransferase-3 (ST3GAL3) in esophageal squamous cell carcinoma (ESCC) and its relationship with patient prognosis and correlation with clinicopathologic characteristics, as well as to investigate the function and molecular mechanism of ST3GAL3 in cell proliferation and migration. Methods: The mRNA and protein expression of ST3GAL3 in ESCC and paired normal tissues were examined by GEO database, qRT-PCR and immunohistochemistry (IHC), respectively. Additionally, the relationship between ST3GAL3 expression and patient prognosis, as well as its correlation with clinicopathological characteristics, was analyzed. We analyzed the expression of ST3GAL3 gene in different ESCC cell lines by CCLE database, and established ST3GAL3-WT and its catalytic site mutant overexpression, as well as ST3GAL3 knockdown and its rescue cells. The cell proliferation, migration and spreading abilities on ECM was assessed using cell proliferation assay and Transwell assay, respectively. The effect of ST3GAL3 on the expression of proteins related to adhesion signaling and the α2,3-sialylation of Integrin α5 and β1catalyzed by ST3GAL3 was detected by Western blot (WB) and lectin-immunoprecipitation (Lectin-IP), respectively. Results: The mRNA expression level of ST3GAL3 was significantly higher in the ESCC tissues than in the normal tissues (P < 0.01). The protein expression level of ST3GAL3 was significantly upregulated in the ESCC specimens compared with the paired paracancer tissues, and the high expression of ST3GAL3 in ESCC was positively correlated with patient poor prognosis and TNM stage (P = 0.004), T classification (P < 0.001), and lymph node metastasis (P = 0.017). ST3GAL3 promoted ESCC cell migration on ECM in a catalytic function-dependent manner. Furthermore, ST3GAL3 mediated cell spreading and adhesion signaling under ECM-coating conditions. Moreover, ST3GAL3 catalyzed the α2,3-sialylation of Integrin α5 and β1. Conclusion: The expression of ST3GAL3 was increased in the ESCC, and its high expression was positively correlated with patient poor prognosis and TNM stage, T classification, and lymph node metastasis. ST3GAL3 enhanced ESCC cell spreading and adhesion signaling on ECM, therefore promoting ECM-mediated cell migration, possibly through the α-2,3 sialylation of adhesion receptors such as Integrin α5 and β1.

Abstract:
Objective: Gram-negative (G-) bacterial bloodstream infections are an important cause of sepsis, and sepsis-associated encephalopathy (SAE) is a common complication in sepsis patients. In this study, the incidence of SAE and the clinical outcome of these patients were summarized by reviewing the data of patients with G- bacterial bloodstream infection. Methods: The data of patients treated in the Emergency Medicine Center of the First Affiliated Hospital of Nanjing Medical University from January 2021 to June 2024 were reviewed. Patients with first blood culture positive G- bacteria after emergency visit, the patients were divided into SAE and non-SAE groups based on the SAE, and the propensity score matching (PSM) was used to plot the 30-day Kaplan-Meier (K-M) survival curves after adjusting for confounding factors between SAE and non-SAE groups. Results: A total of 207 patients were included in the study, and 92 (44.4%) patients experienced SAE with lower 30-day survival in the SAE group than in the non-SAE group (69.6% VS 97.4%, p <0.001). After matching the baseline data of the SAE and non-SAE groups using the PSM method, the 30-day survival rate was even lower in the SAE group (72.3% VS 100.0%, p <0.001), longer ICU stay [5 (0, 11) VS 0 (0, 5), p <0.001], proportion of invasive mechanical ventilation (MV) (40.0% VS 1.5%, p <0.001), proportion of continuous renal replacement therapy (CRRT) (32.3% VS 4.6%, p <0.001), the proportion of vasoactive drugs used (50.8% VS 15.4%, p <0.001), the K-M curve shows that the 30-day survival status of the SAE group was significantly worse than that of the non-SAE group (HR = 8.730, 95%CI: 3.443-22.14, p <0.001). Conclusions:SAE is a common complication in septic patients with G- bloodstream infections and causes a poor prognosis.

Abstract:
Objective: Healthspan refers to the length of time an individual maintains good physical and mental health without serious chronic diseases or functional impairments. In recent years, the role of dietary factors in extending healthspan has received extensive attention. Cheese is considered as a healthy food but its effect on healthspan and remains unknown. This study aims to clarify the association between cheese intake and healthspan, and and further explore the underlying metabolic mechanisms. Methods: This study employed a nested case-control design and defined healthspan terminated (HST) based on eight reported sub-events of HST in UK Biobank (UKB). 93 214 HST participants and 279 642 controls were included. Conditional logistic regressions was used to evaluate the association between cheese intake and HST, and Mendelian randomization (MR) was used to assess the causal effect. Furthermore, we explored the mediating role of metabolites in this relationship by Two-step MR and observational analysis. Results: Cheese intake is a protective factor for healthspan (Ptrend＜0.05). Specifically, participants with high cheese intake (>5 times/week) had a lower risk of HST (OR=0.93, 95% CI: 0.89-0.98) compared to those who never intake cheese. MR analysis confirmed this protective effect. Mediation analysis suggested that plasma high density lipoprotein cholesterol (HDL-C) and glucose mediated 6.33% and 14.82% of this effect, respectively. Conclusion: These findings suggested that cheese intake might improve the healthspan by decreasing plasma glucose and increasing plasma HDL-C. As an important component of healthy diet, cheese intake might be recommended in our daily diet structure.

Abstract:
Objective:?Triple-negative breast cancer (TNBC), a clinically aggressive subtype characterized by the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) expression, exhibits intrinsic therapeutic resistance and a propensity for rapid progression. TNBC displays unique metabolic reprogramming marked by heightened glycolytic dependence, manifested through upregulation of glycolytic enzymes and glucose transporters, augmented glucose uptake, and excessive lactate secretion. Emerging evidence suggests that the lactate-enriched tumor microenvironment may drive malignant progression, although the precise molecular mechanisms remain incompletely understood. The transcriptional coactivator EP300 (E1A-binding protein p300), which possesses histone acetyltransferase activity, serves as a critical epigenetic mediator by coupling metabolic cues with transcriptional regulation through post-translational modifications such as acetylation and lactylation. Mechanistically, lactate-induced histone lactylation facilitates EP300 recruitment to oncogenic promoters (e.g., HIF-1α, MYC), thereby activating proliferation- and metastasis-associated signaling pathways. This study elucidates the functional impact of lactate on TNBC malignancy and unveils an m6A-dependent epigenetic mechanism through which insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3) orchestrates metabolic reprogramming via regulation of EP300.Methods:?TNBC cells were treated with exogenous sodium lactate supplementation to investigate its oncogenic effects. Cellular proliferative capacity was systematically assessed using CCK-8 assay, while clonogenic potential was evaluated through colony formation analysis. Two-dimensional migration dynamics were quantified via scratch wound healing assay, and three-dimensional invasive potential was determined using Transwell chambers. To establish IGF2BP3-knockdown models, lentiviral-delivered shRNA constructs were employed for stable gene silencing. Histone lactylation modification levels were analyzed by Western blotting. Genome-wide identification of IGF2BP3-associated m6A targets was performed through RNA immunoprecipitation sequencing (RIP-seq) and m6A-specific methylated RNA immunoprecipitation sequencing (MeRIP-seq). Key regulatory molecules were validated at transcriptional and protein levels using quantitative reverse transcription PCR (qRT-PCR) and Western blotting, respectively.Results: Sodium lactate treatment potentiated TNBC cell proliferation and migratory capacity, with pan-lactylation levels exhibiting concentration-dependent augmentation. Mechanistic interrogation revealed that IGF2BP3 depletion markedly attenuated histone lactylation modifications. Integrative analysis of RIP-seq and MeRIP-seq datasets identified 699 candidate genes whose transcripts were both specifically bound by IGF2BP3 and harbored m6A modifications. Pathway enrichment analysis demonstrated significant association of these genes with epigenetic regulation and metabolic pathways. Spatial mapping identified substantial overlap between IGF2BP3-binding regions and m6A modification sites on EP300 transcripts. Functional validation confirmed significant downregulation of EP300 expression at transcriptional and protein levels following IGF2BP3 knockdown.Conclusion: Exogenous lactate drives TNBC malignant progression by orchestrating pan-lactylation modifications. Mechanistically, IGF2BP3 governs EP300 expression through m6A-dependent post-transcriptional regulation, thereby mediating a synergistic interplay between histone lactylation and metabolic reprogramming that ultimately propels tumor progression. These findings lay the mechanistic foundation for developing innovative therapeutic strategies targeting the metabolic-epigenetic crosstalk in TNBC.

Abstract:
Perivascular adipose tissue (PVAT) of the carotid artery is a specialized type of adipose tissue closely adjacent to the arterial adventitia, possessing unique anatomical and functional characteristics. Unlike ordinary adipose tissue, PVAT releases a variety of bioactive molecules through endocrine and paracrine mechanisms, interacting with neighboring vascular wall cells and participating in the regulation of local inflammatory responses and vascular homeostasis. The inflammatory status of PVAT is closely associated with the formation, progression, and vulnerability of carotid atherosclerotic plaques, while also playing a significant role in the development and progression of cerebrovascular diseases. In recent years, with the rapid advancement of imaging technologies, non-invasive assessment of PVAT's inflammatory status has become feasible. The application of these technologies provides new tools for the early identification of high-risk patients with cerebrovascular diseases and holds promise for optimizing preventive strategies and personalized treatment. This article systematically reviews the pathophysiological mechanisms of carotid PVAT, the latest advances in imaging assessment techniques, and their clinical application value.

Abstract:
Frailty is a common multi-dimensional clinical syndrome in the elderly, with diverse definitions. Most literature considers frailty as a non-specific state characterized by a decline in physiological reserves and increased vulnerability. As the number of elderly patients undergoing cardiac surgery increases, the impact of frailty on elderly patients undergoing cardiac surgery has received increasing attention from clinicians. This article briefly describes the assessment methods of preoperative frailty, reviews the impact of frailty on the clinical outcomes after cardiac surgery, such as increasing the incidence of adverse prognosis and postoperative complications, reducing the postoperative quality of life of patients, and increasing medical costs, and summarizes the intervention and management methods for elderly patients with heart disease and frailty, which is helpful to clarify the goals of intervention and treatment and can improve the clinical prognosis and quality of life of patients.

Abstract:
Objective: This study compared the long-term prognosis of endoscopic submucosal dissection (ESD) versus surgical treatment in patients with early Siewert type II adenocarcinoma of the esophagogastric junction (AEGJ). Methods: A retrospective analysis was conducted on 562 patients with early Siewert type II AEGJ who underwent ESD or radical surgery at a single tertiary hospital between January 2010 and February 2021, including 393 patients treated with ESD and 169 with surgery. Propensity score matching (PSM) was applied to balance baseline characteristics. Kaplan-Meier analysis was used to compare long-term survival outcomes between the two groups. Results: Among the 562 patients, 393 received ESD and 169 underwent surgery, with a median follow-uP of 57.7 months (range: 6.2–147 months). After PSM, two balanced cohorts of 163 patients each were generated. The 5-year overall survival (OS) rates showed no significant difference between the ESD and surgery groups (92.5% vs. 90.7%, P = 0.734). Similarly, no significant differences were observed in OS (P = 0.95) or disease-specific survival (P = 0.18) between the two groups. The analysis of adverse events showed no significant differences between the two groups in lymph node metastasis (6.7% vs. 7.4%, P = 0.829), local recurrence (4.9% vs. 9.2%, P = 0.130), postoperative stenosis (3.7% vs. 1.2%, P = 0.152), or bleeding (1.2% vs. 0.6%, P = 0.562). However, the incidence of acid reflux symptoms was significantly higher in the surgery grouP (11.0% vs. 3.1%, P = 0.005). Conclusion: Early Siewert type II AEGJ patients treated with ESD or surgery demonstrated comparable long-term survival outcomes, supporting the role of ESD as a viable therapeutic option for this population.

Abstract:
[Abstract]: Objective: To optimise the current strategy of prostate puncture biopsy by analysing the clinical data of high-risk prostate cancer patients, establishing a model to predict the pathological nature of their prostate lesions, and identifying patients who can be exempted from systematic biopsy and undergo targeted puncture alone. Methods: Clinical data of patients who underwent prostate puncture at the First Affiliated Hospital of Nanjing Medical University from January 2022 to June 2024 were retrospectively analysed, and eligible patients were screened and divided into a training set and a validation set. Single-factor and multifactor logistic regression analyses were used to screen the significant correlates of the pathology of prostate targeted biopsy. A predictive model was constructed based on the data from the training set, and the model efficacy was verified in the validation set. Receiver Operating Characteristic (ROC) curves were used to assess the diagnostic performance of the model in both data sets.Results: Age (X1), number of lesions (X2), histological region in which the lesions are located (X3), Prostate Imaging Reporting and Data System (PI-RADS) score (X4), and prostate-specific antigen density (X5) were the variables associated with the patient's prostate targeted biopsy pathology. The mathematical expression of the predictive model is: p=1/[1+e^(-15.770+0.067×X1-0.658×X2+0.381×X3+2.271×X4+5.742×X5)]. The Area under the curve (AUC) of the prediction model was 0.856 (95% confidence interval: 0.812-0.900) in the training set and 0.886 (95% confidence interval: 0.776-0.995) in the validation set.Conclusion: The constructed prediction model for targeted biopsy pathology in high-risk prostate cancer patients can guide the clinical strategy of prostate puncture to maintain good diagnostic performance while reducing the number of puncture needles, thus reducing the occurrence of complications and the waste of medical resources. Keywords: prostate cancer; prostate puncture biopsy; MRI; predictive model;

Abstract:
［］Objective: To investigate the ability of the histological level of the key protein cytoskeleton-associated protein 4 (CKAP4) in urine extracellular vesicles as a biomarker for the progression of diabetic kidney disease (DKD). Methods: A total of 143 type 2 diabetic patients with biopsy-proven DKD and 10 patients with renal malignant tumors were enrolled. Renal endpoints were defined as the doubling of serum creatinine level or progression to end-stage kidney disease (ESKD). The expression of CKAP4 in renal tissue was detected by immunohistochemistry. Spearman correlation analysis was used to analyze the correlation between CKAP4 expression level and clinical indicators. The area under the receiver operating characteristic (ROC) curve (AUC) was calculated to assess whether CKAP4 expression could effectively distinguish patients with poor renal prognosis. Receiver operating characteristic (ROC) curve analysis was used to determine the best cut-off value of CKAP4 score for renal events (highest Youden index). Time-dependent AUC analyses were also performed to characterize the predictive accuracy of CKAP4 beyond 6 months after renal biopsy. In addition, hazard ratios between CKAP4 and DN progression were followed up by Cox proportional hazards models. The clinicopathological factors with statistical significance (p<0.05) in univariate analysis were included as covariates in multivariate Cox proportional hazards model analysis. Kaplan-Meier analysis was used to evaluate the difference in renal survival over 6 months after renal biopsy between CKAP4 high and CKAP4 low groups. Results: Compared with the adjacent normal kidney tissues of tumor patients, the expression of CKAP4 in the kidney of DKD patients was significantly increased (P<0.05). The expression of CKAP4 in renal tissues of DKD patients was different in different stages, and the differences between stage Ⅱ and stage Ⅲ, stage Ⅱ and stage Ⅳ, and stage Ⅲ and stage Ⅳ were statistically significant (P<0.05). The expression of CKAP4 in DKD patients was positively correlated with serum creatinine, urea nitrogen and 24h urine protein, and negatively correlated with eGFR and hemoglobin. During a median follow-up period of 2.22 years, 63 patients (44.06%) had DKD progression. Pearson correlation analysis showed that histological CKAP4 increased with the increase of pathological grade of DKD (r=0.808,p<0.001). Of note, multivariate Cox regression analysis showed that elevated CKAP4 was associated with an increased risk of DKD progression (HR: 4.120,95%CI: 1.730-9.811,p=0.001). In addition, in Kaplan-Meier survival analysis, patients with high CKAP4 expression had a significantly higher incidence of renal endpoint events than those with low CKAP4 expression (P<0.0001). At the same time, we developed a good nomogram including CKAP4 classification to predict the risk of DKD progression (C-index 0.689). Conclusions: Our findings suggest that histological expression of CKAP4, derived from urine extracellular vesicles, is an independent risk factor for renal progression over 6 months after renal biopsy in DKD patients.

Abstract:
Abstract：Objective：This study aims to investigate whether the addition of niacin (NA) to in vitro maturation (IVM) cultures can improve the quality of oocytes derived from aged mice and its mechanism. Methods：Mice at 8 weeks of age were used as the young control group, and mice at 40 weeks of age were used as the old control group. Oocytes at the germinal vesicle (GV) stage were taken and supplemented with 100, 200, and 300 μM niacin, respectively, and the rates of 2 cell and blastocyst formation were observed to determine the optimal concentration. Oocyte quality was assessed by the first polar body extrusion rate, cortical granule distribution, spindle morphology abnormality rate and chromosomal abnormality rate. Mitochondrial function was assessed by mitochondrial membrane potential and adenosine triphosphate (ATP)levels. Oxidative stress levels were assessed by detecting the levels of reactive oxygen species (ROS) in oocytes and mitochondria. Oxidative stress-related proteins: silent information regulator 3 (SIRT3), superoxide dismutase (SOD2), and acetylated superoxide dismutase (AC-SOD2) were detected by western blot (WB). Results：Under the concentration of 200 μM niacin culture medium, the blastocyst formation rate reached its highest level (P <0.05), therefore this concentration was selected as the optimal concentration. Niacin significantly improved the first polar body extrusion rate and cortical granule distribution in M II oocytes, while reducing abnormal spindle rates and chromosomal aberration rates. It also decreased mitochondrial membrane potential, enhanced ATP production, and reduced ROS levels in both oocytes and mitochondria (all P <0.05). Western blot analysis demonstrated that nicotinic acid supplementation significantly increased SIRT3 and SOD2 protein expression (all P <0.05) while markedly decreasing acetylated SOD2 protein expression (P <0.05). Conclusion：Addition of 200 μM niacin to IVM culture medium improves oocyte quality in aged mice by ameliorating the level of mitochondrial oxidative stress and may act by affecting the SIRT3-SOD2 signaling pathway.

Abstract:
Objective: This study aims to establish individualized cerebral metabolic networks in Parkinson's disease (PD) using integrated 18F-FDG-PET/MR imaging and Jensen-Shannon similarity estimation (JSSE) and characterize topological alterations in metabolic networks and their dynamic associations with functional networks. Methods: Twenty-eight patients with clinically confirmed Parkinson's disease [16 males, 12 females, age (63.4±11.3) years] who underwent 18F-FDG-PET/MR imaging at Nanjing First Hospital from August 2022 to May 2024 were retrospectively analyzed, and 20 age- and gender-matched normal controls (NC) with PD patients were included (10 males, 10 females, age 63.0±9.4 years). Individual brain metabolic networks were constructed using the JSSE method, and Matlab 2013b was used to analyze changes in network topological properties and metabolic connectivity between brain regions using Gretna. Data were analyzed using two independent samples t-test and Mann-Whitney U-test, and the Mantel test analyzed correlations between metabolic and functional network matrices in the PD group and the NC group. Results: Compared with the NC group, the PD group showed higher assortativity in terms of global attributes (t = -2.06,p=0.045); in terms of nodal attributes, the centrality of nodal degree in the right sarcolemmal gyrus (t = 3.32, p<0.001) was significantly reduced; 15 key metabolic connectivity parameters were reduced (p<0.001), with the reduction in metabolic connectivity between the left caudate nucleus and the left inferotemporal gyrus being the was the most pronounced. There was a significant positive correlation between the PD metabolic and functional network matrices (r = 0.242, p<0.05), and the correlation was greater than that in the NC group (r = 0.197, p<0.05). Conclusion: The integrated PET/MR and JSSE framework demonstrates clinical efficacy in detecting cerebral topological reorganization and metabolic connectivity aberrations in PD. 18F-FDG-PET/MR imaging is useful for the early diagnosis of PD and for exploring changes in the mechanisms of intrinsic remodeling of the brain in PD from the perspective of brain metabolism and function.

Abstract:
The classification of central nervous system diseases is complicated and the harm is serious. Due to the existence of blood brain barrier (BBB), the treatment of central nervous system diseases has great difficulties in drug delivery. Transdermal Drug Delivery System (TDDS), as a new drug delivery system that delivers drugs into the blood circulation through the skin, has played a huge role in the treatment of central nervous system diseases in recent years. Due to its unique advantages of painless and convenient administration, transdermal patch has good patient compliance and therapeutic effect, and significantly reduces the first pass effect and adverse reactions. This paper reviews the application of transdermal patches in the treatment of central nervous system diseases such as neurodegenerative diseases and mental diseases, and focuses on the research progress of new technologies such as nanocarriers and microneedles in improving the efficiency of drug delivery. However, individual differences and long-term drug safety are still urgent problems to be solved. Future research should focus on the development of new drug delivery technology and clinical transformation application, so as to promote the further development of TDDS in the treatment of central nervous system diseases.

Abstract:
Early childhood is a critical stage of growth and development, and the nutritional status of this period not only affects physical growth and development, but also lays a solid foundation for lifelong health. However, due to the rapid growth and metabolic characteristics of infants and young children, coupled with the immaturity of multiple physiological systems and the high incidence of infectious diseases, this population faces nutritional risks. This review synthesizes relevant domestic and international studies to elucidate the current landscape of infant nutrition risk, as well as the associated influencing factors such as life environment, age, disease, and high-risk conditions. The paper also shows the design, application, scope, and limitations of existing infant nutrition risk screening tools, along with the clinical significance of nutritional risk screening in hospitalized children, outpatient clinics, and specialized settings. The primary objective of this paper is to raise awareness among pediatric clinicians regarding infant nutrition issues and to promote proactive nutritional risk screening, thereby facilitating early identification of nutritional risks and ultimately achieving standardized and scientific nutrition management.

Abstract:
【Abstract】 Objective This cross-sectional study aims to investigate the abnormalities in routine blood parameters among gastric cancer patients and analyze their trends over the course of the disease. Methods This study included the population who participated in the Taihu Tumour Biomarkers Biobank (TBTB) in Wuxi from August 2020 to December 2021, with 1920 cases who already had gastric cancer at baseline as the gastric cancer group and 7680 cancer-free cases matched 1:4 for age and sex as the healthy control group. A cross-sectional survey design was adopted to explore the association between routine blood tests and the prevalence of gastric cancer using multiple linear regression modelling, and the Kruskal-Wallis test was further used to compare the differences in routine blood tests across different stages of the disease between groups. Results Multiple linear regression model showed that hemoglobin (HGB), platelet count (PLT), red blood cell count (RBC), white blood cell count (WBC), mean hemoglobin content (MCH) and mean corpusular hemoglobin concerntration (MCHC) were lower in gastric cancer patients than in controls, with HGB decreasing the most (β=-0.77, 95% CI: -0.82 ~ -0.71, P<0.001), and red blood cell volume distribution width (RDW) (β=0.13, 95% CI: 0.06 ~ 0.17, P<0.001) and hematocrit (HCT) (β=0.16 , 95% CI: 0.10 ~ 0.22, P<0.001) levels were higher than those of the control group,, suggesting that anaemia-related signs were more common in gastric cancer patients. The study found that WBC showed a gradual decreasing trend during the disease progression in GC patients.(P<0.001), and HGB, RBC and hematocrit(HCT) tended to increase with the duration of gastric cancer(P<0.001), but they were still lower than those of the control group. Conclusions This study indicates that GC patients are more likely to exhibit anemia-related abnormalities compared to healthy individuals. Additionally, certain blood routine parameters show significant changing tends with disease progression, providing valuable insights for clinical monitoring and management of GC.

Abstract:
Objective：To investigate the molecular diagnostic value of whole exome sequencing (WES)in the genetic etiology of intellectual disability (ID) or global developmental delay (GDD) and analysis of genetic characteristics in the Chinese cohort. Methods：1096 patients with ID/GDD who were enrolled in Children's Hospital of Nanjing Medical University from January 2019 to December 2021 were selected as the study objects. Inclusion criteria adhered to clinical guidelines for significant developmental milestone delays, with exclusion of non-genetic factors (e. g. , perinatal hypoxia, infection, metabolic abnormalities). We retrospectively analyzed sequence variants and copy number variations (CNVs) detected by Trio- whole exome sequencing (Trio-WES) or proband-only WES, classifying variants according to the American College of Medical Genetics and Genomics (ACMG) guidelines, with pathogenic（P）/likely pathogenic(LP) variants defined as positive results. Results：1096 patients with ID/GDD ranged in age from 1 month to 15 years, with a median age of 24(12, 48) months, including 716 males and 380 females. The overall positive diagnostic rate was 35.31%(387/1096), with monogenic variants identified in 271 patients and CNVs in 116 patients. Among the monogenic variants, MECP2 gene was the most common one（12/271, 4.43%），primarily associated with Rett syndrome, followed by SYNGAP1 and DDX3X. For CNVs, 5.17%（6/116）patients were aneuploidies，with 7q11.23 deletions (associated with Williams syndrome) being most common (8.62%, 10/116). Autosomal dominant inheritance accounted for 71.96% (195/271) of monogenic variants, while X-linked inheritance represented 19.93% (54/271). Sanger sequencing confirmed de novo origins in 68.27%（185/271）of detected variants. Clinical phenotypic analysis demonstrated a significantly higher positive rate in isolated ID/GDD cases compared to those with comorbid autism spectrum disorder(ASD) or attention-deficit/hyperactivity disorder(ADHD)(P＜0.05). Conclusion：The combined analysis of WES and CNV significantly enhances molecular diagnostic yield for ID/GDD. High frequencies of MECP2 variants and 7q11.23 deletions s represent high-frequency findings in Chinese pediatric cohort. De novo variants constitute the primary genetic etiology in this cohort. These findings support the implementation of WES as a first-line clinical diagnostic tool for ID/GDD.

Abstract:
Objective: To investigate the clinical effect of 0.05% cyclosporine A and 0.1% tacrolimus eye drops in the treatment of severe dry eye associated with sjogren's syndrome. Methods: 112 eyes of 56 sjogren's syndrome patients with severe dry eye were continuously included between October 2021 and November 2023, all of them were divided into tacrolimus group (n=28, 56 eyes) and cyclosporine A group (n=28, 56 eyes) according to random comparison table method. The tacrolimus group received 0.1% tacrolimus eye drops twice a day, and the cyclosporine A group received 0.05% cyclosporine A eye drops four times a day. Both groups were treated for 8 weeks. Dry eye symptoms, tear film rupture time, tear secretion test and corneal fluorescein sodium staining score were followed up before and after treatment. Results: (1) There was no significant difference in general clinical data among all patients; (2) There was no significant difference in SPEED score and TBUT time between the two groups before treatment; Compared with before treatment, SPEED score and TBUT time were improved in both groups after treatment. Compared with each other, TBUT time in Tacrolimus group improved better, while SPEED score in cyclosporine A group improved better. (3) There were no significant differences between the two groups before treatment in FL score and SIt index; Compared with before treatment, FL score and SIt were improved in both groups after treatment. The improvement of FL score was similar between the two groups, but the improvement of SIt in cyclosporin A group was better. (4) There were no significant differences in the morphology of meibomian gland and lipid layer thickness between the two groups before treatment; Compared with the same group before treatment, the morphology and lipid layer thickness of meibomian gland were improved in both groups after treatment. Compared with each other, tacrolimus group had better improvement in meibomian gland morphology and lipid layer thickness. (5) Some patients experience transient irritation symptoms after using two eye drops, and their irritation symptoms are relieved within 20 minutes after medication. Conclusion: Both 0.1% tacrolimus and 0.05% cyclosporine A have good therapeutic effects in severe dry eye associated with Sjogren's syndrome, of which 0.05% cyclosporine A has more obvious advantages in improving patient comfort and reducing dry eye symptoms, while 0.1% tacrolimus has better effects in improving meibomian gland morphology and lipid layer thickness.

Abstract:
Objective: To explore the mechanism of MT-RNR2-like protein 1 (MTRNR2L1)-mediated regulation of PANoptosis during the development of Chronic Obstructive Pulmonary Disease (COPD), and to provide new ideas for finding the pathogenesis of COPD. Methods: Bulk RNA Sequencing (Bulk RNA-seq) data and Single Cell RNA Sequencing (scRNA-Seq) data from COPD patients in Gene Expression Omnibus (GEO) were used to explore the cellular composition in COPD patients' lung tissues and to analyse the pathways involved in the development of the disease. PANoptosis was simulated in smoke/lipopolysaccharide (LPS)-exposed mice, and MTRNR2L1 and PANoptosis protein expression was assessed to clarify their roles in the development of COPD. Results: Bulk RNA-seq demonstrated altered expression of T cell response-related genes in COPD patients. Single-cell RNA-seq confirmed decreased CD8+ T cells and increased epithelial cells compared to controls. The anti-apoptotic gene MTRNR2L1 was upregulated in COPD patient immune and epithelial cells. PANoptosis-related genes were reduced in lungs, CD8+ T cells and epithelial cells of COPD patients; Smoke/LPS-exposed mouse lungs exhibit alveolar damage, increased PANoptosis proteins, while MTRNR2L1 overexpression significantly inhibited cellular PANoptosis and downregulated the levels of ZBP1, Caspase-3, GSDMD, and MLKL.Conclusion: The differentially expressed genes in CD8+ T cells and epithelial cells were enriched in pathways related to PANoptosis , suggesting the involvement of PANoptosis in the development of COPD. The process of PANoptosis in the onset and development of COPD was associated with increased expression of PANoptosis-related proteins. MTRNR2L1 exhibited an inhibitory effect on PANoptosis, and regulating PANoptosis may provide new therapeutic opportunities for reducing lung injury and improving lung ventilatory function.

Abstract:
[Abstract] Objective: To investigate the value of N-terminal pro-brain natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT) in predicting long-term mortality risk in patients with acute ischemic stroke (AIS) and to develop and validate predictive models. Methods: This study is a single-center, retrospective study. AIS patients who underwent thrombectomy at the First Affiliated Hospital of Nanjing Medical University between January 2022 and December 2022 were enrolled and followed up for two years. Cox regression and LASSO regression were used to identify factors associated with all-cause mortality. Three predictive models were constructed: basic model, Model 1 (basic model + NT-proBNP), and Model 2 (basic model + hs-cTnT), and their predictive performances were compared. Results: A total of 230 AIS patients were included in the final analysis and were randomly assigned to the training set (n=146) and testing set (n=84). During the follow-up period, 83 all-cause deaths were recorded, with a mortality rate of 37.2%. Multivariate Cox regression showed that each 1000 pg/mL increase in NT-proBNP was associated with a 27% higher risk of 2-year all-cause death (HR = 1.27, 95% CI: 1.15-1.40, p < 0.001). In contrast, ln(hs-cTnT) was not significantly associated with mortality risk (HR = 1.11, 95% CI: 0.89-1.38, p = 0.372). Cox regression and LASSO identified the following mortality-related variables: history of atrial fibrillation, postoperative national institutes of health stroke scale (NIHSS), baseline hemoglobin, white blood cell count, and random blood glucose. These were used to build basic model. Area under the curve (AUC) of basic model was 0.816 in the training set and 0.778 in the testing set. Model 1 had an AUC of 0.866 in the training set and 0.799 in the testing set, showing improved predictive performance. Model 2 had an AUC of 0.811 in the training set and 0.788 in the testing set, with no significant improvement. Conclusion: NT-proBNP is an independent predictor of all-cause mortality in AIS patients and can enhance the predictive ability of mortality risk based on traditional clinical parameter models, contributing to the individualized management of AIS patients.

Abstract:
Current domestic and international lung cancer screening guidelines recommend the use of low-dose spiral computed tomography(LDCT)for lung cancer screening,which has significantly improved the detection rate of early-stage lung adenocarcinoma.According to the Chinese Medical Association's Lung Cancer Clinical Diagnosis and Treatment Guidelines(2024 Edition),patients with stage IA(T1a/b/cN0)lung adenocarcinoma who undergo surgery with negative surgical margins(R0)can have regular follow-ups postoperatively without the need for adjuvant therapy(Class I recommendation, evidence-based).Recent clinical studies have revealed that the prognosis of patients with stage IA lung adenocarcinoma who only receive surgical treatment is influenced by various factors. To further improve patient outcomes, discussions on the need for postoperative adjuvant therapy continue to emerge. Although a unified treatment standard has not yet been formed, this topic remains of significant research value. This article reviews the impact of factors such as tumor size, solid component ratio, micropapillary and solid subtype proportions, lymphovascular invasion(LVI),and the presence of spread through air spaces(STAS)on the prognosis of stage IA lung adenocarcinoma, and discusses the latest postoperative adjuvant treatment plans and their outcomes, providing new insights into the postoperative treatment of stage IA lung adenocarcinoma.

Abstract:
Objective: This study aims to verify the anti-inflammatory effect of baicalin in an inflammatory environment and explore its influence on the odontogenic/osteogenic differentiation of human dental pulp stem cells (hDPSCs), providing a reference for the treatment of pulpitis. Methods: Select early inflammatory dental pulp tissue from humans to make frozen sections and perform HE staining and IL-1β immunohistochemical staining. Human monocyte leukemia cells (THP-1) were differentiated into macrophages and polarized to the M1 subtype under the induction of lipopolysaccharide (LPS) and interferon-γ (IFN-γ). Then, baicalin (50 μM) was used for treatment. The expression levels of INOS, IL-1β, and IL-8 were analyzed using immunofluorescence, real-time quantitative PCR (RT-qPCR), and Western blot. Additionally, the expression changes of LC3B, Beclin-1, and P62 were assessed by Western blot to monitor autophagic flux alterations in macrophages. To further investigate the relationship between inflammation inhibition and autophagy, we employed the autophagy inhibitor 3-MA to block autophagic flux and re-evaluated the expression changes of IL-1β and IL-8. Supernatants from macrophages treated under various conditions were collected, and the conditioned medium was prepared to act on human dental pulp stem cells. The odontogenic/osteogenic differentiation ability of hDPSCs in an inflammatory environment was analyzed by ALP staining, alizarin red (ARS) staining, RT-PCR, and Western blot. Results: The expression of IL-1β around the inflamed area of early pulpitis tissue was significantly increased. After LPS and IFN-γ induced THP-1, THP-1 macrophages polarized from M0 to M1, and the expressions of INOS, IL-1β and IL-8 significantly increased. After co-incubation with 50μM BA for 24 hours, the polarization degree of M1 macrophages significantly decreased, the mRNA levels of IL-1β and IL-8 significantly decreased, while the expression level of IL-6 showed no statistical difference compared with the M1 group. After adding the supernatant of M1 macrophages to hDPSCs and inducing mineralization for 7~21 days, the alkaline phosphatase activity of hDPSCs decreased, the calcium salt deposition significantly reduced, and the expressions of ALP, DSPP, RUNX2, OPN and COL-1 significantly decreased. When adding the supernatant of M1 macrophages treated with BA, the alkaline phosphatase activity of hDPSCs significantly increased, the calcium salt deposition significantly increased, and the expressions of ALP, DSPP, RUNX2, OPN and COL-1 significantly increased. Conclusion: Baicalin can inhibit inflammatory responses by activating autophagy, thereby enabling hDPSCs to function in an inflammatory microenvironment.

Abstract:
Persistent high-risk HPV infection is the main cause of cervical lesions. Cervical cancer is the fourth most frequent malignancy among women globally, posing a severe threat to women's health and lives. Intestinal flora can have anti-tumor effects through immunomodulation, inflammatory response, and metabolite synthesis, according to numerous research conducted in recent years. Research on the relationship between intestinal flora and cervical cancer has revealed notable variations in the diversity and composition of intestinal flora between patients with the disease and healthy controls. These findings have also raised the possibility that certain intestinal flora may serve as biomarkers for cervical cancer prevention and early detection. Furthermore, through the estrogen-mediated "gut-vaginal axis," intestinal flora can interact with the vaginal microbiome, thereby affecting vaginal microecology, HPV infection, and cervical lesions. However, existing studies are mainly based on cross-sectional analyses with small sample sizes and a lack of longitudinal studies and experimental evidence. More thorough research is still required to elucidate the precise linkages and mechanisms of action. The article reviews the research progress on the relationship between intestinal flora and HPV infection and cervical lesions by summarizing the existing research results.

Abstract: Objective To evaluate the clinical value of half-Fourier acquisition single-shot turbo spin sequence based on deep learning reconstruction algorithm (HASTE-DL) T2WI sequence in MRI of pancreas. Methods Sixty-nine patients underwent pancreatic conventional BLADE-TSE-T2WI and based on deep learning HASTE-DL-T2WI sequences scanning using 3.0T MRI. The overall quality, pancreatic sharpness, biliary duct clarity and artifacts of the two groups were qualitatively scored by the Likert 5-point scale method for subjective evaluation. The contrast to noise ratio (CNR) and signal to noise ratio (SNR) of normal tissue and the lesion of the pancreatic of the two groups of images were measured and analyzed. The scanning time of the two sequences were also recorded. Results The overall image quality of the HASTE-DL sequence, the scores of pancreatic sharpness and biliary clarity were better than those of BLADE-TSE sequence (P<0.001).There was no statistically significant difference in the scores of image artifacts between the two groups (P >0.05). The SNR of normal pancreatic tissue, the SNR of lesion and CNR of HASTE DL sequence were better than those of BLADE-TSE sequence (P<0.001). The scanning time of HASTE-DL sequence was 78% shorter than that of BLADE-TSE sequence. Conclusion Compared with BLADE-TSE sequence, the overall quality of HASTE-DL is better, and the pancreatic sharpness and bile duct display clarity are higher, SNR and CNR are better, and the scanning time is shorter. Therefore, HASTE-DL T2WI sequence has good clinical application value in the MRI of pancreas.

Abstract:
Objective:To compare the hemodynamic effects of propofol and remimazolam during the perioperative period in Stanford type B aortic dissection patients. Methods:eighty patients were randomized to receive propofol (Group P) or remimazolam (Group R) for anesthesia. Mean arterial pressure (MAP) and bispectral index (BIS) value were recorded at anesthesia onset (T0), tracheal intubation (T1), 5 minutes after intubation (T2), procedure completion (T3), airway extubation (T4), and 5 minutes after airway extubation (T5). The percentage change in MAP during anesthesia induction was computed as (MAPT2 -MAPT0) / MAPT0, and during the periextubation period, it was calculated as (MAPT5 - MAPT3) /MAPT3. Results:No significant differences in BIS values were observed between the two groups at any time point (P < 0.05). The percentage change in MAP during anesthesia induction was 22.6%±6.5% in Group P and 13.7%±6.9% in Group R, showing a significant difference (P < 0.001). Similarly, during the periextubation period, the mean percentage change in MAP was 21.3%±6.2% in Group P and 11.7%±5.8% in Group R, also indicating a significant difference (P< 0.001). Conclusion：These findings indicate that remimazolam exerted a milder cardiovascular depression effect compared to propofol when delivering same sedation, which has certain positive significance for reducing perioperative complications in these patients.

Abstract:
Pantothenate kinase-associated neurodegeneration (PKAN) is a rare, autosomal recessive neurodegenerative disorder caused by mutations in the PANK2 gene located on chromosome 20p13. The mutation leads to iron deposition in the basal ganglia region of the brain, which causes progressive exacerbation of extrapyramidal symptoms, speech disorders, psychiatric symptoms, cognitive hypoplasia, and retinitis pigmentosa [1]. Here, we report a case of adult-onset atypical PKAN in a patient with psychiatric disorder as the first symptom, followed by dystonia, dysarthria, gait abnormalities, and limb tremor. Neuroimaging showed a typical “tiger's eye sign”. The patient was found to have a heterozygous PANK2NM_1386393.1:c.1172T>A(p.Ile391Asn)/ c.1039G>C(p.Asp347His) mutation by whole-exon sequencing. In addition, we review the pathogenesis, genetic features, clinical manifestations, imaging characteristics, and therapeutic strategies of PKAN patients.

Abstract:
Objective: To identify the International Classification of Functioning, Disability, and Health (ICF) core Sets for Urinary Incontinence in Older Women. Methods: A preliminary questionnaire was developed through a literature search on urinary incontinence in older women across Chinese and international databases. Two professional researchers extracted key concepts from the literature, which were mapped to corresponding items in ICF. A total of 100 eligible patients with urinary incontinence were invited to complete the questionnaire. Items that over 30% of respondents identified as affecting them were designated as Core Item I. Subsequently, the questionnaire was distributed to 35 relevant healthcare workers. Items identified by over 50% of these professionals as impacting older women with urinary incontinence were compiled into Core Items II. The over-lapping items between Core Items I and II will constitute the ICF core items for urinary inconti-nence in older women. For this study, all items within the Core Items Set were presented in the second level. Results: The ICF Core Sets for urinary incontinence in older women includes 29 core items: 8 for "body function (b)," 2 for "body structure (s)," 8 for "activity and participation (d)," and 11 for "environmental factors (e)."Conclusion: The study initially established a core set of ICF items for urinary incontinence in older women, providing an actionable theoretical model for the development of evidence-based rehabilitation management in the clinic.

A total of 292 elderly patients who were selected to undergo AF catheter ablation surgery in the First Affiliated Hospital of Nanjing Medical University, the Third People’s Hospital of Nantong City and the Department of Jingjiang People’s Hospital from June 2023 to? December 2023. Collect the baseline data of the subjects before the operation, and divide the subjects into the frail group (≥3 points), the pre-frail group (1-2 points) and the non-frail group (0 points) according to the Frail scale, and compare the differences between the three groups of patients. After 1 year of postoperative follow-up, it was divided into recurrent group and non-recurrence group according to whether there was AF recurrence during the follow-up period. Comparing the two groups of clinical data, single-factor and multi-factor logistic regression was used to analyze the relationship between frailty and recurrence after catheter ablation and other risk factors for AF recurrence. Through Kaplan-Meier analysis of the survival status of non-atrial fibrillation recurrence event 1 year after surgery, log-rank test to compare the survival differences between groups. Results：A total of 292 elderly patients with AF were enrolled, including 94 patients in the non-frail group, 138 patients in the pre-frail group and 60 patients in the frail group. During 1 year follow-up, 52 patients (17.8%) developed AF recurrence, and the recurrence rate in the frail group was significantly higher than that in the non-frail group and the pre-frail group[38.33%(23/60)vs.10.64%(10/94)vs.13.77%(19/138), P<0.001].Multivariate logistic analysis showed that after adjusting for demographic data and clinical factors, frailty was significantly associated with a higher risk of senile AF recurrence after catheter ablation (OR=3.430,95% CI:1.219-10.233,P=0.022). And AF type (persistent AF), BMI, pro-BNP, LAD are independent risk factors for postoperative recurrence. Conclusions：There is a significant correlation between frailty and recurrence after senile AF catheter ablation, which is a reliable predictor of recurrence after AF ablation.

Abstract:
Objective: To explore the relationship between past history of stroke and clinical features of heart attack and NYHA (New York Heart Association, American Society of Cardiology) cardiac function grading in patients with coronary heart disease. Method: This study included a total of 2327 coronary heart disease patients who were hospitalized at Jiangsu Provincial People's Hospital and Wuxi Second People's Hospital from February 2019 to September 2021. The clinical manifestations and general information of coronary heart disease were collected. According to the clinical characteristics of coronary heart disease patients, they are divided into angina group and myocardial infarction group; The NYHA functional classification is divided into groups of less than three levels, and groups of three levels and above. Use multiple logistic regression analysis to evaluate the relationship between stroke history, clinical characteristics of coronary heart disease patients, and NYHA functional classification. Perform statistical analysis on the data using SPSS 20.0, with P<0.05 indicating statistical significance. Result: In this study, there were 2327 patients with coronary heart disease, including 280 patients with a history of stroke and 2047 patients without a history of stroke. In the general characteristics of patients, age, systolic blood pressure, TC, TG, LDL, HDL, CRP, diabetes, hypertension and renal insufficiency history were significantly different among patients with or without past stroke history (P<0.05). The results of a multivariate logistic regression analysis adjusted for important covariates such as age, gender, and BMI showed that a history of stroke was independently correlated with NYHA functional classification in patients with coronary heart disease (OR=1.85, 95% CI=1.14-3.01, P=0.013).The correlation between stroke history and NYHA functional classification in coronary heart disease patients was further confirmed in subgroup analysis. Conclusion: Past history of stroke is closely associated with cardiac function classification in patients with coronary heart disease, which may have a potential suggestive role for cardiac function classification in patients with coronary heart disease.

Abstract:
Objective: Comparison of short-term efficacy of laparoscopic enucleation versus anatomical resection for hepatic hemangiomas in the right posterior lobe. Methods: A total of 58 patients with hepatic hemangiomas in the right posterior lobe were selected from our hospital between January 2020 and August 2024. The cases were divided into two groups based on the surgical technique: 28 patients underwent laparoscopic enucleation of the hepatic hemangioma, and 30 patients underwent laparoscopic anatomical resection. Various perioperative indicators were observed. Results: There were no statistically significant differences in the preoperative data between the two groups (all P > 0.05). The enucleation group had a significantly shorter surgical duration [(158.9 ± 25.0) min vs. (189.6 ± 66.8) min, P < 0.05], less intraoperative blood loss [(306.4 ± 81.5) mL vs. (378.8 ± 154.5) mL, P < 0.05], and lower total postoperative drainage volume [(422.4 ± 100.0) mL vs. (732.5 ± 318.0) mL, P < 0.05]. On the first postoperative day, the serum levels of aspartate aminotransferase (AST) [(356.4 ± 70.8) U/L vs. (392.8 ± 55.1) U/L, P < 0.05], alanine aminotransferase (ALT) [(369.1 ± 22.2) U/L vs. (405.5 ± 35.9) U/L, P < 0.05], and total bilirubin (TBIL) [(21.6 ± 4.1) μmol/L vs. (25.9 ± 6.8) μmol/L, P < 0.05] in the enucleation group were significantly lower than those in the resection group. There were no statistically significant differences in postoperative inflammatory markers (P > 0.05) or the overall incidence of postoperative complications between the two groups (P > 0.05). Conclusion: Both laparoscopic enucleation and anatomical resection are effective surgical options for treating hepatic hemangiomas in the right posterior lobe. However, laparoscopic enucleation offers advantages such as reduced surgical time, less intraoperative blood loss, and lower total postoperative drainage volume, along with a lesser impact on liver function on the first postoperative day. Therefore, the choice of surgical approach should be guided by individual clinical circumstances.

Abstract:
Objective: To compare the differences between bile duct ligation (BDL) and α-naphthylisothiocyanate (ANIT)-induced mouse models in cholestatic liver injury experiments, and to explore the applicability of both models in such studies. Methods: C57BL/6 male mice were divided into control, sham surgery (Sham), BDL, BDL+SCFA, ANIT, and ANIT+SCFA groups. The BDL and BDL+SCFA groups underwent BDL surgery, while the ANIT and ANIT+SCFA groups were administered ANIT. The BDL+SCFA and ANIT+SCFA groups received water containing short-chain fatty acids (SCFAs) for 14 days. Samples were collected for liver histology, liver function serum biomarker analysis, and inflammatory cytokine detection. Statistical analysis was performed on the data. Results: Mice in the BDL group developed noticeable jaundice and continuous weight loss at one week, with severe jaundice by two weeks. Mice in the ANIT group exhibited mild jaundice early on, which gradually worsened over time, with mild early weight loss and no significant later changes. Gross liver appearance and histopathological analysis revealed common characteristics between the two models, including partial liver fibrosis, hepatocellular necrosis, portal tract fibrosis, inflammatory cell infiltration, and bile duct proliferation. However, these changes were more prominent and occurred earlier in the BDL group, indicating more severe cholestatic liver injury. In contrast, the ANIT group showed milder early changes that progressively worsened over time. Serum biomarkers revealed significant increases in liver transaminase levels in both groups. Early increases in alkaline phosphatase (ALP) and total bilirubin (TBIL) levels were observed in the BDL group, while the ANIT group showed mild early increases, which gradually worsened over time. Serum inflammatory cytokine levels were significantly elevated early in the BDL group, with gradual elevation in the ANIT group. After two weeks of SCFA treatment, there were no significant improvements in jaundice, weight loss, liver serum biomarkers, or inflammatory markers in the BDL group, but significant improvements were observed in the ANIT group, including reduced jaundice, weight loss, liver serum biomarkers, and inflammatory markers. Conclusion: The BDL model has a rapid onset and severe liver injury, making it suitable for studying acute cholestatic liver injury, whereas the ANIT model has a slow onset with progressively worsening liver injury, making it more appropriate for modeling chronic cholestatic liver injury.

Abstract:
With the widespread use of chest low-dose computed tomography, the detection rate of peripheral pulmonary lesions (PPLs) is increasing year by year. Tissue biopsies of PPLs are required to obtain a pathological diagnosis. PPLs are far away from the central airway and close to the pleura, which is difficult to reach by conventional bronchoscopy, and the diagnostic rate and sensitivity are not ideal. Although the diagnostic rate of percutaneous lung biopsy has been improved, it has high complications. Robot-assisted bronchoscopy (RAB) is a new technology for the diagnosis of lung lesions, which improves navigation accuracy, expands the reachable range of the lens, and has the advantages of high accuracy, stability and flexibility, providing higher diagnostic rate and safety than traditional bronchoscopy. RAB can also be used as an interventional platform to combine with the existing ablation therapy for the ablation of lung tumors. With the continuous improvement of science and technology, the application of RAB will be more and more widespread and is the development trend of bronchoscopy.

Abstract:
Stroke, as an acute cerebrovascular disease, is characterised by high morbidity, recurrence, disability, mortality and heavy economic burden, posing an extremely serious threat to human life and health. As a non-invasive, portable and anti-electromagnetic interference brain optical imaging method, functional near-infrared spectroscopy (fNIRS) has been widely used in neuroscience and clinical rehabilitation in recent years. Especially in the neurological rehabilitation of stroke, fNIRS provides a powerful support for rehabilitation assessment, treatment optimisation and neural mechanism research with its unique advantages. In this paper, we will review the main application directions and research progress of fNIRS in this field, the controversies, and the future research directions, aiming to provide a reference for the research and practice of neurological rehabilitation in stroke.

Abstract:
Objective: This study aimed to explore the prognostic value of the chronicity score in patients with diabetic kidney disease (DKD) patients and compare it with the traditional DKD RPS pathological classification. Methods: The clinical data and pathological examination results of 129 patients, who were hospitalized in the First Affiliated Hospital of Nanjing Medical University and pathologically diagnosed with DKD by renal biopsy from January 2014 and September 2020,were retrospectively analyzed in this study. Based on the renal chronicity score, patients were divided into three groups: mild (n=34), moderate (n=50), and severe (n=45). The clinical characteristics and pathological indicators of each group were compared, and the results were evaluated against the DKD RPS pathological classification. Cox regression analysis was used to identify factors influencing poor renal outcomes, Kaplan-Meier survival curves were employed to compare cumulative renal event-free survival rates, and receiver operating characteristic (ROC) curve analysis was performed to assess the diagnostic value of the chronicity score alone and in combination with estimated glomerular filtration rate (eGFR) and 24-hour urinary protein in predicting renal outcomes. Results: Patients with higher chronic lesion scores exhibited worse renal function,more pronounced anemia, and a higher pathological grade according to the DKD RPS classification. The Kaplan-Meier survival analysis revealed that patients with higher chronic lesion scores had significantly lower cumulative survival rates without renal endpoint events, indicating poorer prognosis (P<0.05). Cox regression analysis identified a high chronic lesion score as an independent risk factor for renal endpoint events (P<0.05). The ROC curve analysis demonstrated that the diagnostic value of the chronic lesion score was slightly lower than that of the DKD RPS pathological grade (AUC=0.651 vs. 0.875), though no statistical difference was observed between the two. When combined with eGFR and 24-hour urinary protein, the AUC value of the chronic lesion score increased to 0.810.

Abstract:
Objective: To examine the expression of FBXO6 in glioma tissues and cells and its impact on the proliferation and invasion of glioma cells, and to explore the upstream regulatory mechanism of FBXO6 expression. Methods: The CGGA database was used to analyze the expression of FBXO6 in tumor tissues of glioma patients and its correlation with patient prognosis. RT-PCR and Western blot were performed to check the expression levels of FBXO6 in glioma cell lines (U251, U373, and U87), and U87 cells with the highest expression were screened out. RT-PCR, Western blot, CCK-8, and Transwell experiments were carried out to detect the effects of FBXO6 overexpression and silencing on the proliferation and invasion of U87 cells. U87 cells were treated with U0126 (an ERK1/2 inhibitor), SP600125 (a JNK inhibitor), and Perifosine (an Akt1 inhibitor), and Western blot was conducted to examine the expression and phosphorylation levels of relevant proteins. Subsequently, RT-PCR and Western blot were used to detect the expression changes of FBXO6, and then CCK-8 and Transwell experiments were performed to measure the proliferation and invasion capabilities of U87 cells. FBXO6 was overexpressed in U87 cells, which were then treated with Perifosine, and RT-PCR, Western blot, CCK-8, and Transwell experiments were carried out to investigate the levels of FBXO6 expression, cell proliferation, and invasion. Results: In glioma patients, the expression of FBXO6 in cancer tissues was significantly higher than that in adjacent tissues and was closely associated with poor patient prognosis. All three glioma cell lines, namely U251, U373, and U87, expressed FBXO6, with U87 cells showing the most significant expression. The proliferation and invasion of U87 cells were significantly enhanced after FBXO6 overexpression, while they were significantly weakened after FBXO6 silencing. The Akt1 inhibitor could significantly down-regulate the expression of FBXO6 in U87 cells, whereas the ERK1/2 and JNK inhibitors had no significant effect on FBXO6 expression. The Akt1 inhibitor could significantly reduce the proliferation and invasion of U87 cells, and FBXO6 overexpression could antagonize the above effects. Conclusion: Activation of Akt1 in glioma cells up-regulates the expression of the FBXO6 gene, promoting cell proliferation and invasion.

Abstract:
Objective：To evaluate the clinical effect of 3D reconstruction images of coronary CT angiography in preoperative planning of off-pump coronary artery bypass grafting.Methods：The clinical data of 158 patients who underwent coronary artery bypass grafting from January 2021 to March 2023 in the Department of Cardiac Macrovascular Surgery of the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. Among them, 113 patients underwent conventional coronary artery bypass grafting guided by coronary angiography (conventional group) and 45 patients underwent coronary artery bypass grafting guided by coronary angiography and Three-dimensional reconstruction of coronary artery CT angiography (3D group). The outcome measures included operation time, Intraoperative blood loss,ventilator use time, postoperative monitoring time and hospital stay, postoperative atrial fibrillation, acute kidney injury and other complications, and 1 year postoperative cardiac ultrasound and coronary CT angiography follow-up results.Results：There was no significant difference between the two groups in the time of ventilator use, the time of postoperative monitoring, the time of hospital stay, and the results of coronary CT angiography and cardiac ultrasound follow-up 1 year after surgery (p>0.05) However, the operation time of the 3D group (250.69±41.42) and the conventional group (270.97±57.19), the difference between the two groups was statistically significant (p<0.05), and the amount of blood loss during the 3D operation was less than that of the conventional group (p<0.05)..Conclusion：Compared with conventional CAG guided off-pump coronary artery bypass grafting, the addition of coronary CT angiography can shorten the operation time, reduce the amount of intraoperative blood loss, and obtain better surgical results.

Abstract:
Depression, as a neuropsychiatric disorder with high prevalence, strong invisibility and high relapse rate, is a serious threat to human physical and mental health. The hippocampus, a key brain region for regulating emotional and cognitive functions, has been found to have persistent neurogenesis in its dentate gyrus during adulthood. In recent years, a large body of evidence suggests that adult hippocampal neurogenesis processes are closely related to the pathophysiology of depression. However, the causal relationship between adult hippocampal neurogenesis and the pathology of depression has not been systematically summarized. In this review, we analyzed four aspects of evidence supporting the ‘adult hippocampal neurogenesis hypothesis’ of depression: reduction of adult hippocampal neurogenesis induces depressive phenotypes and related pathologies; depression models reduce adult hippocampal neurogenesis; increased adult hippocampal neurogenesis exerts antidepressant effect; and current antidepressants treatment increases adult hippocampal neurogenesis. This review is the first to comprehensively summarize the causal role of adult hippocampal neurogenesis in depression, providing new perspectives on the mechanisms of depression and antidepressants.

Abstract:
Obstructive Sleep Apnea (OSA) is a potentially life-threatening condition characterized by disordered breathing during sleep, which can result in a range of adverse health outcomes. The prevalence of OSA in women varies across different life stages, with a notable increase observed during pregnancy and post-menopause. The pathophysiological mechanisms underlying OSA in women involve anatomical, physiological, and hormonal alterations, leading to clinical manifestations that differ from those observed in males. Consequently, this article aims to review the current research landscape of female OSA, encompassing epidemiology, pathophysiological mechanisms, diagnostic and evaluative approaches, as well as treatment and management strategies, with the goal of providing novel insights to enhance the diagnosis and treatment of female OSA.

Abstract:
Non-vesicular extracellular nanoparticle (NVEP) are newly discovered nanoscale-sized particles released by cells. Two types of NVEPs with important intercellular communication functions are exomere (EM) and supermere (SM). They differ from extracellular vesicle (EV) in that they are not enclosed by a plasma membrane and have a smaller diameter. Both EMs and SMs contain various signaling molecules including proteins, nucleic acids, and lipids, and their primary function is to realize intercellular communication. The EMs or SMs transport signal molecules to target cells, and are taken up by the target cells, thereby regulating the phenotype and function of the cells. This review mainly focused on the latest research progress of EMs and SMs in the aspects of cell biology, pathophysiology, pathogenesis and potential value.

Abstract:
The lysine methyltransferase 2A (KMT2A) gene, also known as the mixed lineage leukemia (MLL) gene, is involved in normal hematopoiesis and metabolism in humans. KMT2A-rearranged acute myeloid leukemia (KMT2A-r AML) is a specific type of AML characterized by high malignancy. It is insensitive to the conventional AML chemotherapy regimen of anthracycline daunorubicin (DNR) combined with cytarabine (Ara-C) "3+7", resulting in low remission rates and high relapse rates. In recent years, preclinical and clinical studies on KMT2A-r AML have been progressively undertaken. At present, the Menin inhibitor revumenib is the first targeted drug approved by the United States Food and Drug Administration (FDA) for the treatment of relapsed or refractory KMT2A-r acute leukemia, and research on the DOT1L inhibitor pinometostat in combination with various other drugs is ongoing. Additionally, hematopoietic stem cell transplantation (HSCT) and chimeric antigen receptor T-cell (CAR-T) therapies have been subjects of clinical application studies. This article will review the pathogenesis of KMT2A-r AML, targeted drugs, ongoing clinical trials, potential therapeutic targets, and the application of HSCT and CAR-T therapies, aiming to provide new perspectives for the research and treatment of this condition.

Abstract:
Objective: To investigate the clinical significance of anti-SSA positive with or without anti-SSB positive in children with lupus nephritis.Methods:The clinicopathological data of children with lupus nephritis newly diagnosed in the nephrology Department of Nanjing Children""s Hospital from January 1, 2018 to January 1, 2023 were retrospectively analyzed. According to the test results of autoantibodies, they were divided into two groups: anti-SSA positive group with or without anti-SSB positive group and anti-SSA and anti-SSB negative group. The clinical manifestations, SLEDA scores and pathological features were compared among all groups, and the remission of lupus nephritis after six months of treatment was followed up. Results: Eighty-five children with lupus nephritis were enrolled in this study, including 34 children in the anti-SSA positive group with or without anti-SSB positive group (12 children in the anti-SSA positive group with or without SSB positive group, 22 children in the SSA positive group with or without SSB positive group), and 51 children in the anti-SSA negative group with or without SSB positive group. The anti-SSA positive group with or without anti-SSB positive group and the omly anti-SSA positive group had no statistical significance compared with the anti-SSA and anti-SSB negative group, respectively (P > 0.05). The incidence of rash in the anti-SSA and SSB positive group was lower than that in the anti-SSA and SSB negative group, the difference was statistically significant (P < 0.05), and the non-remission rate in the anti-SSA and SSB positive group was higher than that in the anti-SSA and SSB negative group, the difference was statistically significant (P < 0.05).Conclusion:Children with anti-SSB positive lupus nephritis are all accompanied by anti-SSA positive, and children with both anti-SSA and SSB positive lupus nephritis have a lower incidence of rash clinically, but a higher renal unremission rate for half a year, which may require more aggressive renal treatment.

Abstract:
Objective: To combine lymph node ratio (LNR) with central lymph node metastasis (CnLNs) to construct modified lymph node ratio (mLNR), and then investigated the impact mLNR had on prognosis of patients with gastric cancer. Methods: Chi-square analysis was performed to analyze the differences between groups of CnLNs- and CnLNs+ gastric cancer patients, Cox regression analysis was performed to analyze the factors affecting the survival of gastric cancer patients, receiver operating characteristic (ROC) curve was constructed to determine the cut-off value of LNR classification, Kaplan-Meier curve was drawn to visually analyze the survival of gastric cancer patients, and nomogram was constructed to predict the survival and prognosis of gastric cancer patients. Results: Way of gastrectomy (P =0.042), tumor size (P =0.043), degree of differentiation (P =0.001), vascular invasion (P <0.001), neural invasion (P <0.001), T stage (P =0.001) and N stage (P <0.001), CEA (P =0.002) and CA199 (P =0.026) were significantly different between the two groups. Both LNR and CnLNs were able to distinguish the survival of gastric cancer patients, but LNR seemed more effective than CnLNs. In addition, mLNR could well predict the survival of patients with gastric cancer and was an independent risk factor affecting the survival of patients with gastric cancer. Conclusion: Utilizing CnLNs to construct mLNR was an independent risk factor for the survival of gastric cancer patients and was expected to be a novel prognostic indicator for patients with gastric cancer.

Abstract:
Objective: To investigate the impact of myocardial scar and drug treatment response on the risk of ventricular arrhythmia in patients with nonischemic cardiomyopathy(NICM). Methods: A retrospective analysis was conducted on 77 NICM patients with left ventricular ejection fraction (LVEF)≤35% who underwent cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE) and received drug treatment. The LVEF change during the one-year follow-up period were collected. Response to drug treatment was defined as LVEF increase≥10% within one year. The primary outcome endpoint is ventricular tachyarrhythmia (VTA), which includes persistent ventricular tachycardia (VT), ventricular fibrillation (VF), sudden cardiac death (SCD), and aborted SCD. The secondary endpoint is the long-term composite endpoint of VTA, all-cause mortality, and heart failure hospitalization (HFH).Kaplan Meier curves and Log rank tests were used for survival analysis, while Cox proportional hazards regression was used for multivariate analysis.Results: After a median of 34(16-49) months follow-up,The change in LVEF within one year after drug treatment were not related to LGE (P=0.379), but negatively correlated with LGE burden, with a correlation coefficient of -0.295 (95% CI: -0.487~-0.076, P=0.009).During follow up,five patients experienced VTA events. In survival analysis,VTA events were associated with LGE burden (P=0.005) and not with the presence of LGE and drug response (P=0.309,P=0.890). In the multivariate Cox regression model, LGE burden was an independent risk factor of VTA events (HR=1.075, 95% CI 1.002-1.054, P=0.043). The long-term composite endpoint of NICM patients is related to LGE burden and changes in LVEF (P=0.040, P=0.025).Conclusion: LGE burden is an independent risk factor of VTA events in NICM patients, and the occurrence of VTA events is not related to drug treatment response.

Abstract:
Objective This study aimed to examine the relationship between venous thromboembolism and the prognosis of newly diagnosed multiple myeloma (MM) treated with immunomodulatory drugs (IMiDs), and to analyze the risk factors for venous thromboembolism (VTE). To compare the predictive efficacy of the three thrombosis risk assessment scores (Padua, SAVED and IMPEDE score) in VTE in MM patients. Methods A retrospective examination was conducted on the clinical data of 221 NDMM patients treated with IMiDs at Jiangsu Provincial People's Hospital from January 2016 to October 2020, the correlation between VTE and the prognosis of MM patients was analyzed. The VTE risk of patients was quantitatively assessed with Padua, SAVED and IMPEDE scores. The predictive value of the three scales for VTE was compared based on the area under the ROC curve (AUC). Results Of the 221 patients, the incidence of VTE was 15.8%. Patients with age over 75 years, central venous catheterization (CVC), recent surgery, braking on the bed, extramedullary disease, anthracycline using, autoimmune disease and hypoalbuminemia had a higher incidence of VTE. Age over 75 years, CVC, autoimmune disease and hypoalbuminemia were independent unfavorable factors for VTE. Among Paudua, SAVED, and IMPEDE scores, IMPEDE score is superior to the other two scores in efficacy evaluation of predicting the formation of VTE in newly diagnosed MM patients. Conclusion Age over 75 years, CVC, autoimmune disease and hypoalbuminemia were independent unfavorable factors for VTE. IMPEDE score is suitable for predicting VTE in patients with NDMM.

Abstract: Objective: To evaluate the predictive value of preoperative enhanced CT radiomic feature models in comparison with clinical-pathological feature models for disease-free survival (DFS) in patients with non-metastatic grades 2-3 clear cell renal cell carcinoma (ccRCC). Methods: A retrospective analysis was conducted on 315 patients with non-metastatic ccRCC who underwent surgical treatment and were pathologically graded as grades 2-3 between January 2013 and December 2020. Preoperative enhanced CT images, clinical-pathological information, and DFS data were collected. The region of interest (ROI) of the lesion was delineated using ITK-SNAP, and radiomic features were extracted using Python. Patients' radiomic scores were calculated using the least absolute shrinkage and selection operator (LASSO) and Cox regression analysis. Clinical-pathological feature models, radiomic models (corticomedullary phase, parenchymal phase, corticomedullary + parenchymal phase), and combined radiomic and clinical-pathological feature models were constructed to predict patients' DFS efficacy. Results: When predicting DFS in non-metastatic grades 2-3 ccRCC patients, the combined radiomic model of corticomedullary + parenchymal phase demonstrated superior predictive efficacy (C-index: training set 0.848, validation set 0.754) compared to single-phase radiomic models (corticomedullary phase C-index: training set 0.832, validation set 0.701; parenchymal phase C-index: training set 0.842, validation set 0.720). However, the combined model incorporating both radiomic and clinical-pathological features exhibited the highest predictive efficacy (C-index: training set 0.857, validation set 0.832). Conclusion: The model combining radiomic features extracted from preoperative enhanced CT images of corticomedullary and parenchymal phases with clinicopathological features assists in predicting postoperative DFS in non-metastatic grades 2-3 ccRCC.

Abstract:
Objective To investigate the expression of NADH-Cytochrome b5 reductase 2 (CYB5R2) in diffuse large B-cell lymphoma (DLBCL) and its clinical significance. Methods GO enrichment analysis was performed on DLBCL differentially expressed genes in TCGA database by DAVID online platform, and CYB5R2 was screened. The CYB5R2 expression of DLBCL in TCGA database and GTEX database was analyzed by bioinformatics method. The correlation between CYB5R2 expression and clinicopathological features and prognosis in 59 cases of DLBCL with complete follow-up data in our hospital was retrospectively analyzed. Results The expression of CYB5R2 in DLBCL was higher than that in normal lymphoid tissue (P < 0.05). The positive expression of CYB5R2 in the cases with elevated lactate dehydrogenase (LDH) was higher than that in the cases with normal LDH (χ2=4.832, P= 028). The positive expression of Non-GCB subtype cases was higher than that of GCB subtype cases (χ2=4.468, P= 035), and the positive expression of CD10-positive cases was higher than that of CD10-negative cases (χ2=4.468, P= 035). survival analysis showed that the 5-year overall survival (OS) of patients with high CYB5R2 expression was significantly lower than that of patients with zero or low CYB5R2 expression (χ2=4.799, P=0.028). The rate of complete response (CR) in patients with high expression was significantly lower than that of CYB5R2 expression was significantly lower than that of patients with zero or low CYB5R2 expression (χ2=4.799, P=0.028). The complete response (CR) rate in patients with high expression was significantly lower than that in patients with zero/low expression of CYB5R2 (χ2=4.015, P=0.045). Conclusion The high expression of CYB5R2 is associated with poor prognosis in DLBCL patients, suggesting that CyB5R2 plays an important role in the development of DLBCL.

Abstract:
Stroke is an acute neurologic injury caused by ischemia or hemorrhage that stems from a wide range of pathologies, with high rates of morbidity, mortality, and disability. Thrombolysis and endovascular thrombectomy are the only FDA approved methods for the treatment of acute ischemic stroke (AIS), but the clinical benefits of reperfusion therapy are significantly limited by hemorrhagic transformations (HT), resistance to thrombolytic drugs, and reperfusion no-reflow. Although the factors leading to these problems are complex, neutrophils play the most critical role in them. Based on the latest research progress in recent years, this review focuses on the role of neutrophils in mediating the pathophysiological events of AIS, the specific mechanisms by which neutrophils cause HT, thrombolytic drug resistance, and no-reflow after reperfusion therapy, as well as strategies targeting neutrophils to prevent or alleviate these complications following reperfusion therapy, offering new insights for the clinical therapy and drug development of ischemic stroke.

Abstract:
Objective: To investigate the role and mechanism of Iguratimod in interstitial fibrosis of chronic allograft dysfunction (CAD) in transplanted kidneys. Methods: We constructed and validated a mouse model of chronic allograft dysfunction. Iguratimod was administered via gavage. Histological staining was used to assess injury and fibrosis in transplanted kidneys. Immunofluorescence staining , Western blot, and qRT-PCR were utilized to detect fibrosis markers and changes in macrophage-to-myofibroblast transition (MMT) in the transplanted kidneys of CAD mice. TGF-β was used to induce MMT in primary mouse bone marrow-derived macrophages (BMDMs) in vitro, followed by Iguratimod intervention. Transcriptome sequencing was employed to explore the downstream molecular mechanisms by which Iguratimod regulates MMT. Results: We successfully constructed and validated the mouse CAD model. HE, PAS, and Masson staining revealed significant interstitial fibrosis in the transplanted kidneys of CAD mice at 16 weeks post-transplantation. Immunofluorescence staining showed a significant upregulation of MMT in the transplanted kidneys. However, Iguratimod treatment significantly reduced interstitial fibrosis and the number of MMT cells in CAD mice at 16 weeks. In vitro experiments indicated that Iguratimod significantly reduced TGF-β-induced MMT. Transcriptome sequencing results suggested that Iguratimod mitigates fibrosis by inhibiting MMT via the ferroptosis-related pathway. Conclusion: We successfully constructed and validated a mouse CAD model. Iguratimod alleviates interstitial fibrosis in transplanted kidneys and slows the progression of CAD by upregulating the ferroptosis-related pathway to inhibit MMT. This may provide new insights for the further application of Iguratimod in allograft kidney transplantation.

Abstract:
Antibody-drug conjugates (ADCs) are synthesized by conjugating monoclonal antibodies with linkers and cytotoxic drugs. This conjugation harnesses the highly specific targeting capabilities of antibodies along with the potent cytotoxic effects of the drugs, demonstrating significant efficacy in the treatment of breast cancer. Nonetheless, the extensive clinical application of ADCs has revealed instances of resistance in breast cancer patients. In this paper, we provide a comprehensive overview of the structure and mechanism of ADCs, along with their current applications in the treatment of breast cancer. We categorize the mechanisms of ADC resistance into several distinct types: reduction in target antigen-antibody binding, impaired internalization and transport pathways of ADCs, dysfunctional lysosomal activity, abnormal payload release, tumor insensitivity to the payload, and the involvement of Cyclin. Additionally, we discuss the current challenges associated with ADC resistance, ongoing research into novel ADCs, and potential combination treatment strategies.

Abstract:
Objective: This study aims to elucidate the activation status and transcriptional heterogeneity of astrocytes in the mouse brain during the progression of Huntington’s disease (HD) and to screen for and identify differentially expressed molecules on the key issue. Methods: (1) Immunofluorescence was employed to examine the transformation of HD astrocytes into reactive astrocytes at both the early and late stages of the disease, and this transformation was subsequently verified by RT-qPCR; (2) Single-cell dissociation and magnetic bead sorting techniques were utilized to isolate astrocytes from mouse brains for subsequent transcriptome sequencing; (3) Bioinformatics analysis was conducted to identify differentially expressed genes (DEGs) and to perform GO functional enrichment analysis on the transcriptome data from the early and late stages of HD; (4) Genes related to the progression of HD were selected for Protein-protein interaction network (PPI-network) analysis, and the expression of core genes was validated. Results: In the late stage of HD, astrocytes transform into A1-type reactive astrocytes; in the early stage of the disease, DEGs in HD mouse astrocytes were predominantly associated with synaptic functions, such as synaptic cleft and the maintenance of synaptic structure, whereas in the late stage, they were mainly involved in chemotactic activity, signal transduction, and cellular response functions; core genes of astrocytes during HD progression were mainly related to angiogenesis, RNA splicing, metabolism, and muscle movement. Conclusion: In the early stage of HD, astrocytes influence neuronal development and synaptogenesis. Later in the disease course, they transform into neurotoxic type A1 reactive astrocytes. Astrocyte heterogeneity genes that are independent of the aging process can serve as effective molecular markers for the progression and prediction of HD, and the findings are expected to provide a new reference for the early detection and treatment of HD.

Abstract:
To elucidate the potential involvement of amphiregulin (AREG) in the pathogenesis of intestinal fibrosis in Cronh’s disease(CD). Methods: Differentially expressed genes were identified through transcriptome sequencing following AREG(100ng/ml) treatment of human intestinal fibroblasts for 48h, aiming to uncover the underlying mechanisms by which AREG contributes to intestinal fibrosis; Fibrotic and non-fibrotic tissues were obtained from CD patients undergoing surgical resection for clinical validation; cell proliferation and migratory capacity were assessed via Ki67 immunofluorescence and scratch assays, while expression levels of Col1a1、Col6a1、and Col6a3 were quantified using qRT-PCR and α-smooth muscle actin(α-SMA) was quantified by Western blot. Results: Analysis of RNA-seq data revealed that AREG enhances the expression of lysophosphatidic acid receptor 3(LPAR3) in human intestinal fibroblasts. Additionally, elevated levels of lysophosphatidic acid (LPA) were found in the plasma of CD patients with intestinal fibrosis compared to those without it, while LPAR3 expressions increased at the sites affected by fibrosis as opposed to nonfibrotic sites from CD patients. In vitro experiments demonstrated that AREG promotes the secretion of LPA by human intestinal fibroblasts, which subsequently increases the protein expression of LPAR3 and stimulates cell migration, proliferation, activation, and collagen production. The effects on cells can be attenuated by LPAR3 inhibitors. Conclusion: AREG may play a significant role in the pathogenesis of CD-related intestinal fibrosis through the LPA-LPAR3 signaling pathway; thus, targeting the AREG-LPA-LPAR3 axis could represent a promising therapeutic strategy for managing intestinal fibrosis.

Abstract:
Objective To investigate the clinical pattern and influencing factors of pediatric Crohn's disease. Methods To conduct a retrospective analysis of 59 patients who were originally diagnosed with Crohn's disease and treated at the Children's Hospital Affiliated to Nanjing Medical University, from November 2015 to November 2020. All patients’ baseline datum were gathered, including demographics like age and sex, clinical presentation, laboratory, radiological, and endoscopic tests, as well as details on their treatment plan. Patients were followed up until December 31, 2023, and we analyzed the factors which influence the clinical pattern of children with Crohn's disease by logistic regression. Results There were 59 children with Crohn's disease. 11 patients were lost to follow-up, and 48 patients completed long-term follow-up, with a median follow-up of 42 months (range: 36-82 months). The median age of the 48 patients was 12.6 years (range: 1.1-15.9 years) and 29.2% (14 cases) were female. During the follow-up, 1 patient died, 1 underwent partial enterectomy, 7 patients (14.58%) developed new stenotic disease behavior, and 29 patients (60.4%) recurred. During the follow-up period, 31 patients (64.6%) reported a decrease in the severity of intestinal symptoms . Only 2 patients (4.2%) reported an increase in symptom severity, while 5 patients (10.4%) reported chronic persistent symptoms and 10 patients (20.8%) reported chronic recurrent symptoms .The regression models indicated that wasting at the time of initial diagnosis could be a risk factor for patients to progress to the 'severe' pattern (OR, 4.009, 95% CI, 1.047-15.346, P=0.043); the percentage of patients with combined stenosis or perforation was significantly higher in the "severe" pattern than in the "quiescent" pattern (41.2% versus 16.1%); the Crohn's disease pattern was not influenced by the treatment regimen at the time of initial diagnosis. Conclusion Wasting at the time of initial diagnosis could potentially increase the risk of progressing to a 'severe' disease pattern, which may require more aggressive treatment and closer follow-up.

Abstract:
Immune checkpoint inhibitors have been widely used in cancer treatment. Although they are generally better tolerated than chemotherapy, they can cause immune-related adverse events. Among these, immune checkpoint inhibitor-related pneumonitis (CIP) has a relatively high mortality rate, with limited evidence from evidence-based medicine and limited experience in diagnosis and treatment. This article reviews the therapeutic advancements in CIP based on domestic and international guidelines, expert consensus, and relevant studies, with particular focus on the treatment progress of steroid-refractory CIP.

Abstract:
Objective: To analyze the early changes in the gut microbiota of elderly patients with severe burns using high-throughput sequencing of 16S ribosomal RNA (16S rRNA). Methods: Thirteen patients with severe burns (Burn group) and twelve healthy volunteers (Control group) were enrolled according to the inclusion and exclusion criteria. Clinical data and fecal samples were collected from both groups, and 16S rRNA V4 region gene sequencing was performed to assess the relative abundance of various bacterial taxa. The Rarefy method was employed to generate operational taxonomic units (OTUs), and Z-score normalization was applied to identify differentially abundant bacteria. A heatmap for differential bacterial communities was constructed. The number of fecal microbiota OTUs and diversity indices were analyzed using QIIME (version 1.9.1). Linear discriminant analysis effect size (LEfSe) was used to identify dominant bacterial groups. The functional abundance of the microbiota was predicted using PICRUSt2 software. The correlations among differential bacterial taxa at the genus level were visualized using the igraph package in R language. Data were analyzed using independent sample t-tests, Wilcoxon rank-sum tests, chi-square tests, and Kruskal-Wallis tests, with a significance threshold of P < 0.05. Results: The early gut microbiota of severe burn patients was predominantly composed of Firmicutes and Bacteroidota. Twenty-three bacterial genera exhibited significant differences between the two groups (P < 0.05). The heatmap of differential bacterial communities indicated that the Burn group had a slightly lower abundance of microbial taxa than the Control group. LEfSe analysis indicated that the LDA scores for Clostridia in the Control group and Bacilli in the Burn group were both greater than 4. Compared to the Control group, the Burn group exhibited a significant increase in bacterial species in one phylum, two classes, six orders, six families, and ten genera. The microbial distribution dendrogram suggested that Bacilli were the primary distinguishing marker for the Burn group, while Clostridia were the main marker for the Control group. KEGG functional prediction analysis indicated no significant differences between the two groups (P > 0.05). Combined network visualization analysis revealed that Firmicutes exerted the greatest influence, with 136 bacterial genera showing significant positive or negative correlations (| cor | > 0.3; P < 0.05), primarily through synergistic interactions. Conclusion: There are significant differences in the early gut microbiota of elderly patients with severe burns compared to their healthy peers, characterized by a reduction in beneficial bacterial species and abundance, an increase in the proportion of anaerobic bacteria, and decreased microbial diversity, along with certain synergistic and antagonistic interactions among different microbiota.

Abstract:
Cancer patients are often combined with depressive symptoms, which is not conducive to the recovery of the disease. Currently, the treatment of cancer with depression is based on drugs, but it is prone to interact with antitumor drugs, and the excessive drug burden may lead to poor patient compliance, affecting the treatment and prognosis of the disease. Therefore, it is particularly important to discover safer and more effective treatments. This article reviews the progress of non-pharmacological therapies at home and abroad in recent years, with a view to providing ideas for optimizing the treatment of cancer with depression.

Abstract:
Objective: To investigate the spectrum distribution and prognosis of patients with terminal ileum lesions, and to explore the diagnostic value of clinical, endoscopic features and peripheral blood indexes in the etiology of the disease. Methods: This study was a retrospective study, including patients who underwent colonoscopy and found terminal ileum lesions in Jiangsu Province Hospital from January 2014 to June 2021. General information, medical records, endoscopy and pathological reports of the patients were collected, and clinical and endoscopic characteristics and etiological diagnosis were statistically analyzed. The patients with CD and non-specific terminal ileum ulcer were screened, and the clinical and endoscopic characteristics and peripheral blood indexes of the two groups were compared. Results: A total of 956 patients with terminal ileal lesions were included, 93 of whom had a clear diagnosis, including CD, intestinal tuberculosis, benign tumors, adenocarcinoma, etc., 425 were lost to follow-up, and another 438 patients with unknown causes. Among the patients with unknown diagnoses, 293 had a repeat colonoscopy, and 182 of them showed that the lesions disappeared. Finally, 22 patients with CD and 73 patients with non-specific terminal ileal ulcer were screened out. Compared with the latter, patients with CD have a higher incidence of abdominal pain at initial diagnosis and are more likely to show endoscopic features of ileocecal valve involvement. Peripheral blood inflammation-related indicators such as platelets, hemoglobin, albumin, platelet/lymphocyte ratio, and neutrophil/lymphocyte ratio have certain value in assisting in the diagnosis of CD. The combined diagnostic value of the five indicators is higher, with an area under the curve of 0.83. Conclusion: Most terminal ileal lesions are non-specific benign lesions and have a good prognosis. For patients whose terminal ileal lesions, especially ulcers, are first discovered under colonoscopy, attention should be paid to their clinical symptoms and endoscopic characteristics, and combined with changes in peripheral blood inflammation-related indicators, it is helpful to diagnose the cause of terminal ileal lesions.

Abstract:
Objective To investigate the correlation between triglyceride-glucose (TyG) index and the risk of progression of diabetic retinopathy (DR). Methods 521 patients with type 2 diabetes mellitus who were hospitalized in the Department of Endocrinology of the Affiliated Suqian Hospital of Xuzhou Medical University from June 2022 to June 2023 were included in the study, and the patients were classified into 206 cases in the no-diabetic retinopathy (NDR) group, 159 cases in the non-proliferative diabetic Retinopathy (NPDR) group, and 156 cases in the proliferative diabetic retinopathy (PDR) group, according to the criteria of diagnosis and staging of DR. General data and major biochemical indexes of patients in each group were compared, TyG index was calculated, and the correlation between TyG index and the risk of DR progression was analyzed. Results Multifactorial logistic regression showed that TyG index was an independent risk factor for DR. Ordered logistic regression showed that corrected confounders included sex, age, body mass index (BMI), disease duration, glycated haemoglobin (HbAlc), total cholesterol (TC), low-density lipoprotein (LDL), high density lipoprotein (HDL), creatinine (CR), uric acid (UA) and diabetic peripheral neuropathy (DPN), there was a significant correlation between TyG index and the risk of DR progression, Q3 vs Q1 OR=4. 18 (2.55-6.85), and the risk of DR progression increases with the TyG index. Subgroup analysis proved that the Q3 group was still more likely to develop severe DR. The results of interaction analysis showed that there was a significant interaction between TyG index and age&BMI, patients aged >60 years and BMI >24 were at higher risk of DR. Conclusion TyG index is an independent risk factor for DR, and there is a significant correlation between TyG index and the risk of DR progression. The risk of DR progression increases with the TyG index. The risk of DR was higher among older and overweight patients.

Abstract:
Objective:To construct a predictive model based on the clinical and imaging features of lung adenocarcinoma to predict occult mediastinal lymph node metastasis. Methods:A retrospective analysis was conducted on the patients of First Affiliated Hospital of Nanjing Medical University from 2009 to 2019 who underwent surgical treatment and lymph node dissection with/without occult mediastinal lymph node metastasis on pathology.Multiple clinical and imaging features of the patient were collected.Univariate and multivariate analyses were used to screen independent predictors and construct imaging models for multiple CT characteristics.A receiver operating characteristic (ROC) was established to evaluate the predictive efficacy and clinical utility value of each model. Results:Of the 2,287 patients , there were 780 cases of lung adenocarcinoma, of which 145 had lymph node metastases.Univariate analysis suggested that tumor size, axial location, nodal nature, morphological features, pleural pulling sign, and type of pleural adjacency were significantly associated with lymph node metastasis.Multivariate analysis indicated that tumor size (OR = 1.019; 95% CI: 1.002-1.036; p = .028), nodal nature (OR = 0.361; 95% CI: 0.202-0.646; p = .001), pleural involvement (OR = 1.835; 95% CI: 1.152-2.924; p = .011), and presence of mediastinal pleural adjacency (OR = 1.796; 95% CI: 1.106-2.919; p = .018) were independent predictors of occult mediastinal lymph node metastasis.The AUC value of the imaging model was 0.75, with the sensitivity and specificity of 86.2% and 53.1%, respectively. Conclusion:The imaging model based on chest CT plain scan shows an excellent clinical value in predicting occult mediastinal lymph node metastasis of lung adenocarcinoma，which can provide clinicians with a basis for noninvasive preoperative decision making and help thoracic surgeons choose more appropriate surgical treatment options.

Abstract:
Objective: To investigate the effect of remaining a certain degree of flexion deformities(FD) during total knee arthroplasty(TKA) on efficacy of knee osteoarthritis with severe FD. Methods: A total of 95 patients with knee osteoarthritis with severe FD who underwent primary TKA in the First Affiliated Hospital of Nanjing Medical University from October 2013 to September 2021 were retrospectively analyzed. There were 24 males and 71 females, aged 68.85±4.83 years(range from 58 to 79 years). The body mass index was 26.01±4.50 kg/m2(range from 19.70 to 39.39 kg/m2). Based on intraoperative correction of severe FD, the group was divided into an intraoperatively completely-extended group(52 cases)and an intraoperatively incompletely-extended group(43 cases). The operation time, operative blood loss, postoperative swelling degree of lower limbs and the incidence of postoperative complications were recorded, and the hospital for special surgery(HSS)score, activities of daily living(ADLs)and visual analogue scale(VAS)were recorded to compare the differences between the two groups. Results: All patients successfully completed the operation and were followed up for 35.85±1.99 months(range from 33 to 39 months). The intraoperatively incompletely-extended patients got a shorter operation time(P=0.001), less operative blood loss(P<0.001)and milder swelling of the lower limbs(the postoperative circumference of 15 cm above the patella, P<0.001; the postoperative circumference of 10 cm below the patella, P<0.001). The incompletely-extended patients had greater FD than the completely-extended patients at 3 months(P=0.016)after surgery, but gained less pain(P=0.014). No significant differences were observed in postoperative HSS and ADLs scores between the two groups of patients. At 6 months, 12 months, 24 months and 36 months postoperatively, there were no statistically significant differences in FD, HSS, ADLs and VAS between the two groups. There was no statistically significant difference in the HSS improvement between the two groups within 3-6 months, 6-12 months, 12-24 months and 24-36 months after surgery as well. The incompletely-extended patients during TKA had a lower incidence of deep vein thrombosis(P=0.048)compared with the completely-extended patients. There was no statistical difference in the incidence of medium-term and long-term complications between the two groups. Conclusion: When treating knee osteoarthritis with severe FD, remaining a certain degree of FD during TKA does not affect the recovery of knee range of motion and function, while the incidence of deep vein thrombosis is lower.

Abstract:
Objective: To investigate whether carotid intima-media thickness (CIMT) and carotid plaque are associated with cognitive impairment in patients with Parkinson's disease (PD). Methods: According to the Monterill Cognitive Assessment Scale, 225 PD patients were divided into three groups: normal cognitive function (NC) group(n=41), mild cognitive impairment (MCI) group (n=76) and dementia (PDD) group (n=108). The differences of clinical and carotid ultrasound indexes were compared, and the independent factors of PD cognitive impairment were analyzed by multiple linear regression. Results: The educational level of NC, MCI and PDD groups showed a downward trend (P < 0.05); H&Y rating, UPDRS-III, Hamilton Depression Scale, Pittsburgh Sleep Quality Index Scale, cystatin C level, CIMT, carotid plaque detection rate and carotid plaque vulnerability score showed an increasing trend (P < 0.05). Regression analysis showed that high education level (P < 0.001) was an independent protective factor for PD cognitive impairment, and CIMT thickness (P=0.002) and high H&Y (P=0.001) were independent risk factors for PD cognitive impairment. Conclusion: Carotid atherosclerosis was associated with cognitive impairment in PD patients.

Abstract:
Objective: To investigate the effect of mitochondrial targeting drug Mitochonic acid 5 (MA-5) on renal fibrosis and its mechanism. Methods: Twenty-four 8-week-old SPF C57BL/6J male mice were randomly divided into four groups: control group, MA-5 group, unilateral ureteral ligation (UUO) group and UUO+MA-5 group. The ureter and kidney were exposed by modeling operation, and the UUO group and the UUO+MA-5 group were sutured after ligation,while the other two groups were directly sutured after exposure. From the 2nd day after operation, the MA-5 and the UUO+MA-5 group were given MA-5 by gavage continuously until the 7th day, and the control and UUO group were given corn oil by gavage. The mice were sacrificed on the 7th day after UUO, and the kidney and blood samples were collected. Subsequently, Masson and Sirius Red staining were used to detect the degree of renal fibrosis. The expression of α-SMA and Collagen I were explored by immunohistochemistry. Furthermore, Western Blot was used to detect the expression of mitochondrial related proteins. Mouse renal tubular epithelial cells were cultured in vitro and stimulated with transforming growth factor-β (TGF-β). Western Blot was used to detect the expression of α-SMA, Fibronectin and Vimentin in tubular epithelial cells with or without MA-5 intervention. Results: Seven days after UUO, Masson and Sirius Red staining of renal tissue showed that the UUO group had severe renal fibrosis, and the UUO+MA-5 group had significantly reduced renal fibrosis compared with the UUO group. The results of Western Blot and immunohistochemistry showed that the expression of α-SMA and Collagen I in the UUO+MA-5 group was significantly lower than that in the UUO group (p<0.05). Further study showed that mitochondrial biosynthesis, fusion and movement were decreased in the UUO group, and the expression of manganese superoxide dismutase (SOD2) was decreased. MA-5 treatment significantly increased the expression of Mitofilin in the kidney of UUO mice, improved mitochondrial function, and increased the expression of PGC1-α, Mfn1, Miro1 and SOD2 (p<0.05). The results in vitro showed that MA-5 could reduce the expression of fibrosis-related proteins induced by TGF-β in cultured tubular epithelial cells (p<0.05). Conclusions: Renal fibrosis occurs in mice after UUO, and MA-5 can reduce renal fibrosis by maintaining mitochondrial homeostasis. In vitro experiments showed that MA-5 could attenuate TGF-β induced tubular epithelial cells fibrosis.

Abstract:
Objective: To investigate the effect and possible mechanism of total flavonoids of Desmodium styracifolium (TFDS) on the formation of renal calcium oxalate stones. Method: Selective macrophage Rictor gene knockout mice (Csf1r Cre -/-, Rictorfl/fl, C57BL/6J) and their control group mice (Csf1r Cre+/-, Rictorfl/fl, C57BL/6J) were used to establish renal calcium oxalate stone models, and TFDS intervention was administered. Collect kidney tissues from various groups of mice for routine staining, immunohistochemical fluorescence staining, flow cytometry, and other examinations to explore the effect of TFDS on the formation of renal calcium oxalate stones; Primary extraction of bone marrow-derived macrophages (BMDMs) from the two types of mice was performed, and TFDS intervention was administered to investigate the mechanism through PCR, cell fluorescence staining, flow cytometry, and other examinations. Result: The number of renal calcium oxalate stones in the renal tissue of mice with renal calcium oxalate stones+knockout group was significantly higher than that in the renal calcium oxalate stone group, accompanied by a significant increase in polarization of M1 macrophages; After TFDS intervention in two groups of mice, the renal tissue of the TFDS+renal calcium oxalate stone group showed a significant decrease in renal calcium oxalate stones and M1 macrophage polarization, while the formation of renal calcium oxalate stones in the TFDS+renal calcium oxalate stone+knockout group showed no significant changes compared to the non-intervention group. Cell experiments showed that after Rictor knockout, BMDM exhibited significant polarization of M1 macrophages, while polarization of M1 macrophages was significantly reduced in the TFDS+BMDM group; however, there was no significant change in polarization after TFDS intervention in Rictor knockout of BMDM compared to before intervention. Conclusion: TFDS can effectively and safely reduce the formation of renal calcium oxalate stones in vitro, possibly by inhibiting Rictor regulated polarization of M1 macrophages.

Abstract:
Objective：To analyze the genetic characteristics of chromosomes of sperm donor volunteers in our sperm bank for more than ten years, and to explore the role of sperm bank chromosomal karyotypes analysis and screening in avoiding adverse pregnancy outcomes after sperm donor treatment. Methods：The chromosomalkaryotypes examination results of 3591 sperm donors who underwent sperm screening at the Jiangsu Human Sperm Bank from January 2012 to December 2023 were retrospectively analyzed to classify the distribution and types of chromosomal karyotypes abnormalities. Results：Among the 3591 sperm donors, there were 62 cases of karyotype abnormalities, accounting for 1.73% of all volunteers, of which the most common were pericentric inversions (30/62), followed by secondary constriction region enlargement (13/62), and then short-arm enlargement (7/62) andtranslocation (6/62). In addition to this, there were 3 cases of satelliteenlargement, 1 case of double enlargement, 1 case of enlarged centromere and 1 case of markerchromosome. Conclusion:In view of the known or potential adverse effects of karyotype abnormalities on pregnancy outcomes and offspring health, sperm banks are required to conduct rigorous cytogenetic screening of sperm donor volunteers to circumvent the risk of failure of subsequent sperm donor treatments and to fulfil the societal role of assisted conception and eugenics.

Abstract:
Fibroblasts play important functions in the synthesis and remodeling of extracellular matrix and are involved in physiopathological processes such as maintaining tissue structure, mediating immune regulation, inflammation and tumorigenesis. Fibroblasts participate in and maintain the atrophy and chemotaxis of the gastric mucosa in the precancerous stage. When the gastric mucosa becomes cancerous, the activated fibroblasts interact with gastric cancer cells and other components of the tumor microenvironment, shaping a microenvironment suitable for the growth of gastric cancer and thus promoting gastric cancer proliferation, invasion, and metastasis, but the mechanism of action is complex and needs to be further explored. Meanwhile, fibroblasts have been found to be closely associated with chemoresistance in gastric cancer. Therefore, drugs targeting fibroblasts may provide a new direction for cancer treatment and play an important role in reducing the risk of cancer recurrence and metastasis, decreasing chemoresistance and improving cancer prognosis.In this study, we provide a review on the mechanism of fibroblasts promoting gastric mucosal carcinogenesis and their role in evaluating the effect of gastric cancer drug therapy, in order to provide a theoretical basis for the study of the role of fibroblasts in the pathogenesis and treatment of gastric cancer.

Abstract:
Objective: To investigate the relationship between symptoms, exercise capacity and hyperinflation in chronic obstructive pulmonary disease (COPD) patients; and to try to establish a nomogram prediction model based on spirometry to predict the occurrence of hyperinflation in COPD. Methods: COPD patients and controls with normal lung function were recruited to perform the 6-minute walk test (6MWT). The COPD patients were divided into a hyperinflation group (39 patients) and a non-hyperinflation group (62 patients) according to the GOLD guidelines. Clinical data, 6MWT and lung function were analysed in the three groups. Variables were screened by the Boruta algorithm combined with Lasso regression, and the variables were analysed by univariate and multivariate logistic regression, to establish a nomogram prediction model of the occurrence of hyperinflation in COPD patients and to assess its predictive effect. Results: Compared to the non-hyperinflation group, patients in the hyperinflation group had a shorter 6-minute walk distance (6MWD), a smaller 6MWD as a percentage of predicted value (6MWD%pred), and a mean 6MWD%pred of （86.74 ± 12.54）%, accompanied by the symptoms of a more severe drop in walking pulse-oximetry and a more severe post-exercise leg fatigue. The hyperinflation group had a higher proportion of patients with mMRC ≥2 and CAT ≥10. The results of logistic regression analysis suggested that vital capacity(VC) (β=-2.636, OR=0.072 , 95% CI: 0.022 ~ 0.232), Maximal mid-expiratory flow of predicted(MMEF%pred) (β=-0.147, OR=0.863, 95% CI: 0.790 ~ 0.944) were independent predictors of the occurrence of hyperinflation in COPD patients. The mean values of VC and MMEF%pred in the hyperinflation group were （2.51 ± 0.60）L and （23.05 ± 6.48）%, respectively. The area under curve (AUC) of the reciever operating characteristic (ROC) curve of the nomogram model was 0.897 (95% CI: 0.836~ 0.957, P<0.01). The mean absolute error of the calibration curve was 0.023. Conclusion: The nomogram model based on the spirometer parameters VC and MMEF%pred can predict the occurrence of hyperinflation in COPD patients. When ventilatory dysfunction was present on spirometry testing in COPD patients, a decrease in the parameters VC and MMEF%pred predicted an increased risk of combined hyperinflation. These patients tend to have reduced exercise tolerance and are multisymptomatic, suggesting the need for clinical focus. This predictive model provides primary community care with an easy-to-implement, method of assessing patients with COPD and facilitates guidance for individualised treatment and rehabilitation.

Abstract:
Parkinson"s disease (PD) is the second most common neurodegenerative disease. The pathological aggregation of α-synuclein (α-syn) is a biomarker of PD, which is closely related to the occurrence and development of PD. Finding an inhibitor that can inhibit the formation of pathological aggregates such as α-syn Oligomer and α-syn fibrils at the early stage of the disease is of great significance for the treatment of PD. In recent years, significant progress has been made in the research of aggregation inhibitors targeting α-syn. This review summarizes the structure, physiological function, pathological mechanism and aggregation inhibitors of α-synuclein, aiming to provide a reference for the further research and development of α-syn aggregation inhibitors.

Abstract:
Objective: This study aimed to observe and quantify the continuous changes in dental movement and trabecular microstructure in tension and pressure zones of rats under orthodontic force using in vivo Micro-CT scanning. Methods: A 50g orthodontic force was applied to the left maxillary first molar of five male 8-week-old SD rats. The rats were scanned in vivo at different time points using Micro-CT. The distance of orthodontic tooth movement was calculated in a unified spatial coordinate system. Additionally, trabecular micro-morphological and mechanical property-related parameters in the tension and pressure zones of the moved teeth were measured and statistically analyzed. Results: There was significant displacement of the rat molars within the first 0-3 days, with a decrease in movement rate between 3-14 days, followed by an increase in rate from 21-28 days (P<0.001). Multiple trabecular parameters in both tension and pressure zones showed turning points at 7 days and 14 days, respectively. Specifically, bone volume fraction (BV/TV) and trabecular thickness (Tb. Th) first decreased and then increased, while total porosity volume [Po. V(tot)], structure model index (SMI), trabecular separation (Tb. Sp), and fractal dimension (FD) exhibited the opposite trend. During the early stage of tooth movement, the slope of increase in trabecular parameters was greater in the tension zone compared to the pressure zone. In the later stage of tooth movement, there were significant differences in the values of BV/TV, Po. V(tot), SMI, and Tb. Sp between the tension and pressure zones (P<0.05). Conclusion: Orthodontic tooth movement in rats occurs in three stages. There are differences in trabecular microstructure remodeling between tension and pressure zones, with bone mass and bone quality both decreasing first and then increasing, reaching their lowest points around 7 days and 14 days, respectively. The active phase of bone resorption in the tension zone occurs earlier, and bone formation in the alveolar bone of the tension zone lags behind bone resorption in the pressure zone.

Abstract:
Objective:To explore the role of genes related to pyroptosis in the pathogenesis of Polycystic ovary syndrome (PCOS) and construct an accurate prediction model for PCOS. Methods: Three micro RNA(mRNA) expression profiles were obtained from the Gene Expression Omnibus (GEO) database ,and analysis was carried out on the differential expression of pyroptosis-related genes (PRGs) between PCOS patients and normal healthy women.Four machine learning algorithms, namely the Generalized Linear Model (GLM), Random Forest (RF), Support Vector Machine (SVM), and Extreme Gradient Boosting (XGB), were employed to identify the gene characteristics of PCOS. Real?time quantitative PCR(RT-qPCR) method was utilized to detect the expression levels of specific genes in the plasma of 10 PCOS patients and 10 normal healthy women.Results: A predictive model and a nomogram were established based on PRGs to accurately predict PCOS. Among the four machine learning algorithms,the XGB method demonstrated the highest accuracy in validating the model using two independent datasets, which was further supported by decision curve analysis. Consensus clustering revealed two distinct subgroups within PCOS cases, with Cluster2 exhibiting higher level of immune infiltration compared to Cluster1. Differential expression analysis was then conducted to identify differentially expressed genes (DEGs) between the two subtypes, followed by pathway enrichment analysis on the model genes. Clinical verification showed that the expression levels of PYD and CARD domain containing(PYCARD), Absent in melanoma 2(AIM2), Chromatin modif-ying protein 4B(CHMP4B) and NOD-like receptor family pyrin domain containing 2(NLRP2) in the plasma of PCOS patients were significantly higher than those of the healthy control group, with statistical differences. This verifies the accuracy of the PCOS prediction model based on PRGs.Conclusion: This study offers preliminary insights into the association between PCOS and pyroptosis,a precise predictive model for PCOS.

[Abstract] (86) [HTML] (0) [PDF 0.00 Byte] (0)

Abstract:
Autism spectrum disorder (ASD) is a neurodevelopmental disorder that typically arises in early childhood, with core symptoms predominantly manifesting in language and social interaction. Although traditional diagnostic tools, such as the Autism Diagnostic Observation Schedule-2 (ADOS-2), are widely used, they often have limited accessibility and objectivity in younger children and in primary healthcare settings. Due to its strong quantitative capabilities, relatively low cost, and high sensitivity to early speech anomalies in infants, speech recognition technology has emerged as a promising avenue for ASD diagnostic support. This paper systematically reviews the latest research on the application of speech recognition in early screening across different age groups, diagnosis of comorbid emotional issues, assessment of disease severity, and multimodal data integration. The findings show that extracting acoustic features—such as fundamental frequency, speech rate, and pauses—can effectively distinguish individuals with ASD from typically developing children, while also identifying comorbidities like anxiety, depression, and ADHD. Furthermore, multimodal fusion (e.g., neuroimaging, physiological signals, and behavioral data) can further improve diagnostic accuracy. Nevertheless, challenges persist, including inadequate data diversity, limitations related to dialect and age applicability, confounding effects of comorbid conditions, and concerns over privacy.

Abstract:
Cervical cancer is the fourth most common cancer among women throughout the world, especially in low- and middle-income countries, and is closely associated with human papillomavirus (HPV) infection. This review found that PAX1 gene methylation can be used as a marker for early diagnosis, and it has higher specificity and sensitivity than traditional methods, as discussed through the analyses and discusses of existing literature. Meanwhile, PAX1 methylation status can also be used to assess the prognosis of cervical cancer after treatment. However, due to factors such as small clinical samples and short research periods, further in-depth studies are still needed. Nevertheless, the study of PAX1 methylation still has a vital role and broad application prospect in the diagnosis and treatment of cervical cancer, which provides a direction for the screening and diagnosis of cervical cancer.

Abstract:
Objective: This study aims to investigate the predictive role of baseline body composition parameters，including specifically myosteatosis, sarcopenia, and the cachexia index, on disease-free survival (DFS) in patients with gastrointestinal stromal tumors (GIST) receiving postoperative imatinib therapy. Methods: This single-center retrospective study included 82 moderate- or high-risk GIST patients who underwent tumor resection and were pathologically diagnosed at the First Affiliated Hospital of Nanjing Medical University between January 2014 and December 2018. Body composition parameters including skeletal muscle index, subcutaneous and visceral adipose index, and low-attenuation muscle area were quantified via CT imaging at the L3 vertebral level to assess the presence of myosteatosis or sarcopenia in patients. Univariate and multivariate Cox proportional hazards regression models were employed to analyze the relationship between these parameters and DFS. Kaplan-Meier survival curves were generated, and the model's predictive performance was evaluated using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). Results: The median follow-up duration for the 82 patients was 72 months, with 22 cases (26.83%) experiencing recurrence during this period. Multivariate Cox regression analysis revealed that myosteatosis (P=0.010), high-risk status (P=0.011), and C-KIT exon 13 mutation (P=0.002) were independent risk factors for DFS. The nomogram based on these factors yielded area under the ROC curve of 0.728 and 0.746 for DFS at 3 and 5 years, respectively, indicating strong predictive performance. Additionally, decision curve analysis confirmed the nomogram’s utility in clinical decision-making. Conclusion: Myosteatosis, risk stratification, and C-KIT exon mutation types represent important prognostic factors for DFS in GIST patients. Compared to sarcopenia, myosteatosis shows greater clinical value in predicting prognosis and may serve as a novel prognostic factor for GIST patients.

Abstract:
Objection: To investigate the efficacy and safety of intravenous thrombolysis in elderly patients (aged≥80 years) with branch atheromatous disease (BAD). Methods: Old patients with BAD admitted to the Nanjing Brain Hospital Affiliated to Nanjing Medical University from January 2021 to June 2024 were retrospectively collected and divided into 60-79 years old group and ≥80 years old group according to age. Clinical data, early neurological impairment, and 90-d efficacy and safety were compared between the two groups. Results: A total of 156 patients were included in this study, divided into 60-79 years old group (n=114) and ≥80 years old group (n=42). The ≥80 years old group had higher baseline brain natriuretic peptide (BNP), prothrombin time (PT) and D-dimer levels than those of the 60-79 years old group (all P<0.05). In the effectiveness analysis, compared with the 60-79 years old group, National Institute of Health Stroke Scale (NIHSS) scores at 24 h and 7 d after intravenous thrombolysis in ≥80 years old group were higher. There were significant differences between the two groups (all P<0.05). Meanwhile, ≥80 years old group was more likely to experience early neurological deterioration (END) (38.1% vs. 12.3%, P<0.05). There were no significant differences in 90 d modified Rankin scale (mRs) scores, 90 d NIHSS scores, and the proportion of mRs≤2 and mRs≥4 between the two groups (all P>0.05). In addition, in the safety analysis, there was no statistical significance in the parenchymal hemorrhagic transformation and gastrointestinal bleeding between the two groups (all P>0.05), while the proportion of mucosal bleeding and stroke-related pneumonia (SAP) in ≥80 years old group was higher than that in 60-79 years old group, with statistically significant differences (all P<0.05). Conclusion: Patients ≥80 years with BAD can still benefit from intravenous thrombolysis, but END and complications need to be concerned.

Anti-nuclear antibodies in assisted reproductive technology: clinical relevance and therapeutic implications

[Abstract] (77) [HTML] (0) [PDF 0.00 Byte] (0)

Abstract:
In the application of assisted reproductive technology (ART), the impact of antinuclear antibody (ANA) on the pregnancy outcomes of infertile patients has garnered attention. ANA, as a biomarker of autoimmune abnormalities, has been extensively studied for its association with unexplained infertility and its potential effects on oocyte and embryo quality. Current evidence suggests that a positive ANA status may be associated with reduced ovarian reserve function, poor embryo development, decreased clinical pregnancy rates, and increased risk of miscarriage. The level of ANA in follicular fluid is considered a sensitive indicator for predicting autoimmunity-related infertility. Specific ANA subtypes, such as anti-dsDNA antibodies and anti-centromere antibodies (ACA), are related to oocyte maturation disorders and delayed embryo development. Nevertheless, the direct link between a positive ANA status and the decline in female fertility and adverse reproductive outcomes requires further research for clarification. The review also discusses various treatment options for ANA-positive patients, including glucocorticoids, low-dose aspirin, and hydroxychloroquine, aiming to provide guidance for clinical practice in ART and future research directions.

Abstract:
Objective: To analyze the value of continuous finger pulse oxygen saturation (SpO2) monitoring in guiding oxygen therapy in patients with pneumonia complicated with hypoxemia. Methods: 101 subjects with viral pneumonia complicated with hypoxemia were enrolled, 56 with continuous finger pulse oximetry monitoring and 45 with routine monitoring. Two groups were compared about hospital days, arterial blood gas counts, course of oxygen therapy. Effects of two monitoring on blood oxygenation and inflammatory factors [interleukin 6（IL-6）and C-reactive protein （CRP）] on day（7±1） were evaluated an ANCOVA model. Data from the continuous monitoring group was divided into escalation and no escalation groups for subgroup statistical analyses according to whether an oxygen therapy escalation event occurs within 48h of admission. Correlations between monitoring parameters and inflammatory and immune factors were analyzed. The monitoring data of patients was analyzed who had been upgraded to bilevel positive airway pressure（BiPAP） oxygen therapy who had another oxygen therapy escalation event under 48h. The diagnostic value of pulse oximetry monitoring parameters for the diagnosis of early oxygen therapy escalation events was explored using receiver operating characteristic（ROC） analysis. Results: The ABGs counts, the length of oxygen therapy initiation escalation and reaching the maximum parameters were smaller in the continuous monitoring group than routine group（P＜0.05）. Continuous monitoring versus routine monitoring was associated with significantly greater inflammatory factors improvements in oxygenation index on day7±1 (LS mean difference, 29.52(95% CI:2.27 - 56.76， P=0.034)), IL-6(-4.83(95% CI:-9.58 to -0.83， P=0.046)) and CRP(-4.83(95% CI:-9.58 to -0.83， P=0.046)).The differences in monitoring parameters in the continuous pulse oximetry monitoring group in lowest SpO2（SpO2L）, mean SpO2（mSpO2）, the percentage of time with SpO2 below 86%、88%、90%、92%、and 94%（T86、T88、T90、T92、T94）, standard deviation were statistically significant between the upgraded group and the no-upgraded group（P＜0.05）. IL-6, CRP and immunoglobulin G were significantly correlated with pulse oximetry parameters. In addition, continuous monitoring parameters on BiPAP days showed events of sudden oxygen desaturation accompanied by increasing pulse rate. Such hypoxic events were found to be associated with BiPAP offline, which can be used to diagnose escalation events. Conclusion: Continuous finger pulse oximetry monitoring parameters T92 can identify the risk of progressive exacerbation of hypoxic events at an early stage. The area of decline of oxygen desaturation under BiPAP day offline can be used as a predictor of oxygen therapy escalation events. Continuous finger pulse oximetry monitoring can help guide decisions about oxygen therapy regimens in patients with pneumonia complicated by hypoxemia.

Methods: CT angiography (CTA) data of 212 patients with AAS and 212 normal controls were retrospectively enrolled. There were 120 cases of ascending aorta dissection (AD), 52 cases of intramural hematoma (IMH) and 40 cases of LIT of ascending aorta. The imaging parameters included maximal diameter, minimal diameter and area of the ascending aorta at the lesion, adjacent normal ascending aorta and descending aorta at corresponding level respectively. Aortic remodeling index was calculated as maximal diameter/minimal diameter. Results: The maximal diameter of involved ascending aorta in LIT group were larger than those in AD group and IMH group (P < 0.05), the remodeling index was also higher than that in the AD group and IMH group (P < 0.05). Binary logistic regression analysis suggested that the maximal diameter of ascending aorta was an independent predictor of LIT occurrence (OR: 1.533, P＜0.001). Conclusion: The imaging parameters of LIT are different from those of other types of AAS lesions. When the maximal diameter of the ascending aorta was greater than 40.5 mm in patients with suspected AAS, LIT should be considered clinically.

Abstract:
Objective: To explore the relationship between Hemoglobin Glycation Index (HGI) and carotid intima-media thickness (cIMT) in patients with type 2 diabetes mellitus (T2DM). Methods:A total of 302 inpatients with T2DM at the Affiliated Yancheng Maternal and Child Health Hospital of Yangzhou University Medical School were enrolled.The clinical?parameter?including cIMT, fasting plasma glucose (FPG), and glycated hemoglobin (HbA1c) were measured. HGI was calculated based on HbA1c and FPG, with high HGI defined as HGI ≥ 0 and low HGI defined as HGI < 0. The relationship between cIMT and HGI was observed. Results: Among the 302 patients with T2DM, 140 cases (46.4%) had thickened cIMT. The proportion of high HGI in the cIMT thickening group was higher than that in the normal cIMT group [51（36.4%）vs 31（22.8%），P< 0.05]. Duration of diabetes, smoking rate, hypertension rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), estimated glomerular filtration rate (eGFR), HbA1c, proportion of high HGI, and low-density lipoprotein cholesterol (LDL-C) were higher in the cIMT thickening group than in the normal cIMT group (P< 0.05). HbA1c and HGI were positively correlated with cIMT (r = 0.257, 0.399, P < 0.05). Logistic regression analysis showed that both HGI and HbA1c increased the risk of cIMT thickening [OR 1.511（95% CI 1.237~1.846）vs OR 1.287（95% CI 1.053~1.571）]. Conclusion: The prevalence of atherosclerosis is high in patients with T2DM, and HGI may be a new indicator of atherosclerosis risk in T2DM patients, in addition to HbA1c.

Abstract:
Objective: To evaluate the risk factors for traumatic brain injury (TBI) combined with traumatic cervical spinal cord injury (TCSCI) in patients with multiple traumas based on emergency CT scans, and their impact on prognosis. Methods: A retrospective analysis was conducted on the data of 218 patients with multiple traumas who were admitted to the emergency department of the First Affiliated Hospital of Nanjing Medical University from January 2020 to December 2022 and were not excluded for TCSCI. Based on the cervical MRI results after admission, the presence of TCSCI was determined, and patients were divided into TCSCI and non-TCSCI groups. Multivariate logistic regression analysis was used to screen for independent risk factors, construct a receiver operating characteristic (ROC) curve prediction model, and perform internal validation. Results: Sixty-nine patients (31.7%) had concurrent TCSCI. Multivariate logistic regression analysis showed that higher head abbreviated injury scale (hAIS) scores (OR=1.552, 95% CI: 1.101-2.188), sub-axial injury classification (SLIC) scores (OR=1.235, 95% CI: 1.006-1.517), and paraplegia symptoms (OR=3.810, 95% CI: 1.115-13.020) were independent risk factors for TCSCI. The area under the ROC curve of the prediction model was 0.9 (95% CI: 0.859-0.941). The model's performance was evaluated using the Hosmer-Lemeshow test, indicating good discrimination and calibration of the prediction model. Conclusion: hAIS, SLIC scores, and paraplegia symptoms are independent risk factors for TCSCI in patients with multiple traumas. For patients with multiple traumas who are not excluded for TCSCI, emergency CT scanning and evaluation of hAIS, SLIC scores, and paraplegia symptoms may effectively screen for high-risk TCSCI patients.

Abstract:
Objective: This study aims to explore the impact of the course of non-traumatic osteonecrosis of the femoral head (ONFH) on pain, functional recovery and quality of life after total hip arthroplasty (THA). Methods: Patients undergoing THA treatment at the First Affiliated Hospital of Nanjing Medical University from September 2022 to January 2024 due to terminal ONFH were retrospectively analyzed. Patients were divided into short course group (course of disease ≤3 years) and long course group (course of disease>3 years) according to the length of the course of disease. Compare the duration of surgery, hospital stay, total blood loss, preoperative and postoperative pain VAS scores, hip joint function Harris scores, Leg Length Discrepancy (LLD), Muscle Fat Infiltration (MFI), Pelvic Obliquity Angle (POA), and the incidence of postoperative complications between two groups of patients. Results：A total of 219 patients were included, 149 patients were in the short course group and 70 patients were in the long course group. Compared to the short disease duration group, patients in the long disease duration group exhibited longer operative times(P＜0.05) and hospital stays (P＜0.01), greater total blood loss (P＜0.05), higher Visual Analogue Scale (VAS) pain scores preoperatively and at postoperative days 3, 5, and 1 month (P＜0.05), and lower Harris hip scores at 6 weeks and 3 months postoperatively (P＜0.05). Additionally, there was a greater preoperative LLD、MFI and larger preoperative and postoperative Pelvic Obliquity Angles in the long disease duration group(P＜0.05). However, there was no significant difference between the two groups in pain VAS score 3 months after operation, hip Harris score 6 months after operation, leg length discrepancy and postoperative complications (P＞0.05).

Abstract:
Objective: Early detection of very low birth weight infants (VLBWI) in fetal growth restriction (FGR) enables prompt clinical intervention. This study aimed to evaluate the predictive value of placental intravoxel incoherent motion (IVIM) parameters and brain volume, derived from fully automated fetal brain segmentation, for identifying VLBWI in FGR. Methods: This study retrospectively included 23 pregnant women with FGR, categorized into VLBWI group (n = 8) and non-VLBWI group (n = 15) based on birth weight. We compared brain structures as a percentage of intracranial volume and placental IVIM parameters (true diffusion coefficient [D], pseudo-diffusion coefficient [D*], perfusion fraction [f], and placental area) between two groups. Diagnostic efficacy of these parameters were evaluated by using receiver operating characteristic (ROC) curve analyses. Results: Placental D values were significantly lower in VLBWI group compared to non-VLBWI group (1.38±0.04 10-3 mm2 /s vs 1.44±0.07 10-3mm2 /s t=-2.109, P=0.047). Additionally, placental area was smaller in VLBWI group (155.84 ± 34.69 cm2 vs 200.41 ± 47.95 cm2 t=-2.315, P=0.031), while the percentage of lateral ventricle volume relative to intracranial volume was greater in VLBWI group (3.00 ± 0.55 % vs 2.53 ± 0.33 % F=4.528, P=0.046). The areas under the ROC curve for placental D value, placental area, and lateral ventricle as a percentage of intracranial volume were 0.767, 0.783, and 0.792, respectively. After incorporating fetal lateral ventricle as a percentage of intracranial volume, placental D value, and placental, the area under the ROC curve increased to 0.892. Conclusion: Placental IVIM parameters and fetal brain volume may serve as potentially effective imaging markers for distinguishing VLBWI in cases of FGR.

Abstract:
Objective: Non-ST-elevation myocardial infarction (NSTEMI) complicated by acute heart failure (AHF) frequently leads to unfavorable outcomes. The inflammatory response and immune dysregulation play a crucial role in the development and progression of this disease. This study aimed to explore the predictive value of the systemic immune inflammation index (SII) in the early development of AHF in NSTEMI patients. Methods: A retrospective study was carried out to collect the clinical data of NSTEMI patients admitted to the cardiovascular department of the First Affiliated Hospital with Nanjing Medical University (Jiangsu Provincial People's Hospital) from September 2023 to September 2024. Spearman correlation analysis was employed to investigate the correlation between the admission SII and the peak value of N-Terminal Pro-Brain Natriuretic Peptide (NT-proBNP) within one week after admission. Based on the receiver operating characteristic curve (ROC) and the Restricted Cubic Spline based on logistic regression (RCS) analysis, the specific relationship between SII and the risk of AHF in NSTEMI patients was explored. Results: A total of 202 NSTEMI patients were included, among whom 104 (51.5%) developed AHF within one week of admission. The level of SII in patients with AHF was significantly higher than that in patients without AHF [1390.55 (939.45, 2459.93) vs 667.15 (431.58, 1140.25), P < 0.001]. The area under the ROC curve was 0.745 (95%CI: 0.6777-0.812, P < 0.001). Spearman correlation analysis indicated that there was a linear correlation between the admission SII and the peak value of NT-proBNP within one week of admission, and the correlation coefficient was 0.317 (P < 0.001). The RCS curve demonstrated a linear positive correlation between the risk of early AHF in NSTEMI patients and SII. Conclusion: The SII exhibits predictive value for the early onset of AHF in NSTEMI patients, with the risk of early AHF increasing as SII levels rise.

Abstract:
Abstract:Objective: A soothing liposome emulsion was developed by selecting Madecassoside and Ectoin as the primary ingredients. The transdermal absorption of the emulsion was subsequently evaluated. Method: The optimal ratio of Madecassoside and Ectoin, capable of eliciting anti-inflammatory and barrier repair activities, was identified through cellular assays. The preparation of hydroxy Madecassoside-Ectoin liposomes was conducted utilizing thin film hydration; subsequent characterization involved the determination of particle size, dispersibility coefficient, and charge using the Malvern particle size analyzer.The morphology was observed under projective electron microscope.The contents of Madecassoside and Ectoin in solution were determined by high performance liquid chromatography. The encapsulation rate and drug loading were determined by dialysis method. The transdermal characteristics of the liposome emulsion were evaluated via the Franz diffusion cell method. Results: A mass ratio of 1:9 for Madecassoside to Ectoin demonstrated optimal anti-inflammatory and barrier repair capabilities. Under these parameters, the liposome preparation conditions were optimized with a phosphorus-bile ratio of 5:1 and a drug-to-lipid ratio of 1:10.The encapsulation rate of Madecassoside in the liposomes was 51.33%, the drug loading capacity of Madecassoside was 0.35%, the encapsulation rate of Ectoin was 26.39% and the drug loading capacity of Ectoin was 1.2%. The particle size is 166.53 nm, the potential is -29.63 mV, and the PDI is 0.2.Over a 24 hour period, the solution demonstrated a lower cumulative permeability compared to the aqueous control, without exhibiting an abrupt release; instead, a sustained release effect was observed. Conclusion: The liposome emulsion prepared in this experiment has a high drug load and stable internal particle distribution, and can achieve slow-release effect on the skin surface and prolong the action time of the effective substance.

Abstract:
Objective: Melanoma is one of the human malignant tumors with high drug resistance and difficult to treat. Ferroptosis is a new type of programmed cell death, and inducing ferroptosis is a new strategy for the treatment of melanoma. Annexin A5 (ANXA5) has been shown to be abnormally expressed in many types of tumors. This project is to explore the correlation between ANXA5 and ferroptosis in melanoma and provide guidance for melanoma treatment targeting ferroptosis. Methods: Based on the Human Protein Atlas database, ANXA5 expression in tissues and tumors were systematically analyzed. Human melanoma sections were used for detecting ANXA5 by immunohistochemical analysis. Knockout of AnxA5 was constructed in melanoma cell line B16F10 by a CRISPR/Cas9 system, then the effect of ANXA5 on ferroptosis was determined by CCK8 and LDH assay in B16F10 cells. RNA-seq was further performed to identify the possible target molecules of ANXA5 related to ferroptosis. Finally, the regulatory role of ANXA5 on ferroptosis sensitivity was detected in different melanoma cells. Results: ANXA5 is abnormally high expressed in melanoma, and knockdown or knockout of ANXA5 promoted the sensitivity to ferroptosis in melanoma cells. Acyl-CoA synthetase long-chain family member 4 (ACSL4) as a key regulator of ferroptosis,was negatively correlated with ANXA5 expression. Overexpression of ANXA5 reduced the level of ACSL4 and showed resistance to ferroptosis. Conclusion: In melanoma cells, knockdown of ANXA5 enhanced the sensitivity to ferroptosis via upregulating ACSL4, suggesting that ANXA5 might be a potential target of ferroptosis for melanoma therapy.

Abstract:
Objective: This study aimed to evaluate the predictive value of the neutrophil-to-lymphocyte ratio (NLR) and the systemic immune-inflammation index (SII) in forecasting rapidly progressive interstitial lung disease (RPILD) in patients with anti-melanoma differentiation-associated gene 5-positive dermatomyositis (anti-MDA5₊^DM).Methods: We retrospectively analyzed the clinical and laboratory data of 124 patients with anti-MDA5₊^DM. Cox regression analysis was employed to identify independent risk factors associated with the development of RPILD and mortality. Receiver operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off values for predicting adverse outcomes.Results: Among the 124 patients, 36 (29.03%) developed RPILD, and 39 (31.45%) died during the follow-up period. Multivariate Cox regression analysis identified elevated NLR was an independent risk factor for RPILD, while elevated SII was independently associated with mortality. The ROC curve analysis demonstrated that an NLR exceeding 6.118 serves as a significant predictor for RPILD, and an SII above 875.791 is indicative of increased mortality risk. Conclusion: NLR and SII are accessible, cost-effective, and reliable prognostic indicators for patients with anti-MDA5₊^{DM, providing valuable}guidance for clinical management and risk stratification.

Abstract:
Objective: To explore the changing regularity of the incidence trend of four types of hepatitis (hepatitis A, hepatitis B, hepatitis C and hepatitis E) in China before and after the COVID-19 pandemic from 2019 to 2023, and provide a reference for the prevention and treatment of hepatitis after the epidemic. Method: Based on the descriptive statistics and seasonal decomposition of the four hepatitis time series from 2012 to 2023 in China, the monthly cases before and after the COVID-19 pandemic in 2019 and 2023 were compared and analyzed, as well as the long-term trend, seasonal factors and the dynamic change of variance contribution rate of the time series. Result: During the COVID-19 epidemic from 2020 to 2022, the average monthly cases of four types of hepatitis were lower than that in 2019 before the epidemic，each type of hepatitis had reached its lowest historical value since 2012, and the monthly cases of 2023 after the epidemic appeared an upward trend. The decomposition of time series shows that the seasonal factors of hepatitis A, B, C and E in 2012-2019 and 2012-2023 are highly correlated, with correlation coefficients of 0.964, 0.964, 0.947 and 0.977 respectively (all p<0.001). The variance of the time series of the four types of hepatitis from 2012-2019 to 2012-2023 shows an upward trend, and the long-term trend variance contribution rates show an upward trend, with correlation coefficients of 0.979, 0.981, 0.890, and 0.938 with variance (all p<0.05)，and the seasonal factor variance contribution rates show a downward trend, with correlation coefficients of - 0.978, -0.986, -0.954, and -0.936 with variance (all p<0.05). Conclusion: The decomposition of the time series is helpful to study the regularity of the long-term trend changes and periodic fluctuation of hepatitis，the long-term trend is obvious for the time series diagram of hepatitis A or B, and the periodic fluctuation is obvious for the time series diagram of hepatitis C or E. The epidemic prevention and control have reduced the monthly casas of four types of hepatitis, which has a significant impact on the long-term trend of monthly casas and has not changed the cyclical characteristics of the low and peak periods of incidence; faced with the challenge of an increase in the cases of hepatitis after the epidemic, it is necessary to strengthen the monitoring of hepatitis after the epidemic, study the regularity of hepatitis incidence, and do a good job in prevention, control and treatment.

Abstract:
U2 small ribonucleoprotein (U2 snRNP) is a kind of splicing body that plays a key role in the process of human nuclear splicing. The maturation of mRNA, including the processing, splicing and transport of 5 'and 3' ends, is closely related to U2 snRNP. The intron branching site sequence is identified by U2 snRNP in splice assembly. U2 snRNP maintains the transcription of essential repair factors in the body. In addition, it can prevent the transcriptional site from forming R-loop structure and directly promote DNA repair. Studies have shown that U2snRNP exists in a variety of human cancer tissues, and its main feature is the mutation of its core component gene and the increased expression level of core component.These changes further affect the migration,proliferation, invasion and other cellular behaviors of tumor cells, and are the key factors in the occurrence and development of tumor. In view of the molecular regulatory role of U2 snRNP in tumors, it is expected to become a new target for clinical diagnosis, treatment and drug therapy.The purpose of this article is to comprehensively review the mechanism of U2 snRNP in cancer.

Abstract:
［］ Objective: To review the application and clinical effect of superficial temporal fascia fat flap in late-stage temporomandibular joint internal derangement. Methods: This study included 23 joints in 18 patients with late-stage internal derangement. All patients underwent TMJ discectomy and reconstruction simultaneously with pedicled superficial temporal fascial fat flap at the Department of Maxillofacial Surgery of the Affiliated Hospital of Stomatology of Nanjing Medical University from July 2022 to December 2023. Through regular follow-up,the preoperative and postoperative(more than 3 months) maximal interincisal opening, pain visual analogue scale(VAS),and self-assessment of joint function were compared. Radiological examinations were performed to evaluate the change in TMJ space. Results: The improvement of the mean preoperative mouth opening of (25.00±9.06mm)(11~40mm) to a mean postoperative mouth opening of (34.39±4.59mm)(25~42mm) was found to be statistically significant (P<0.001). The mean VAS pain score on mouth opening decreased significantly from 50 (25, 75) points to 0 (0, 25) points (P<0.001), while the VAS pain scores on diet reduced from 50 (0, 75) points to 0 (0, 0) points (P=0.002). The mean scores on the self-assessment of joint function improved from (58.61±9.97) points preoperatively to (81.67±7.67) points postoperatively and were found to be statistically significant (P<0.001). Compared with the preoperation, postoperative radiological examinations showed that the anterior, superior and posterior joint space were significantly increased after surgery (P<0.05). Conclusion: Patients with late-stage temporomandibular joint internal derangement who underwent TMJ discectomy and immediate reconstruction with pedicled superficial temporal fascial fat flap could effectively improve mouth opening, relieve pain, and maintain the joint space.

Abstract:
Objective: To investigate the value of Whole exome sequencing (WES) in the control analysis of prenatal ultrasound diagnosis of fetal abnormalities (including structural malformations and soft indicators) whose etiology was not clarified by Chromosome microarray analysis (CMA)..METHODS: Eighty-one patients with negative results of invasive prenatal diagnosis (CMA) after ultrasound examination of fetal abnormalities detected at the Maternity Hospital of Nanjing Medical University from January 2022 to January 2024 were selected for WES. Genetic variants were classified according to the American Society for Medical Genetics and Genomics Genetic Variation Classification Criteria and Guidelines. Pathogenic and possibly pathogenic variants were categorized as positive results, and clinical significance unknown, benign, and possibly benign were categorized as negative results. RESULTS: The 81 ultrasound anomalies consisted of 47 monosystemic (58.02%) and 34 multisystemic (41.98%) anomalies.WES detected a total of 14 (17.28%) positives, including 7 each of monosystemic and multisystemic anomalies, while the remaining 67 were negative (82.72%). The most common ultrasound abnormalities in positive fetuses were cardiovascular system abnormalities and skeletal system abnormalities, both in 5 cases (35.71%), followed by urinary system abnormalities in 4 cases (28.57%). In addition, 2 fetuses had combined nuchal translucency (NT) thickening at early stage (14.29%), and multiple abnormalities were found by ultrasound at mid-trimester. CONCLUSION: Fetuses with ultrasound anomalies, especially when combined with cardiovascular, skeletal, urinary anomalies or multisystem anomalies, are recommended to undergo WES testing if CMA testing fails to clarify the etiology, which may identify new potential causative genes.

Abstract:
The gut-lung axis plays a critical role in the progression of respiratory diseases, with gut microbiota facilitating bidirectional regulation between the respiratory and gastrointestinal systems. Metabolites produced by gut microbiota not only influence gut microbiome composition but also impact respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD), pulmonary hypertension, and viral pneumonia through direct or indirect mechanisms via the gut-lung axis. This review explores the involvement of gut microbiota-derived metabolites in respiratory disease pathophysiology, aiming to provide new insights into potential mechanisms, preventive strategies, and therapeutic approaches for respiratory conditions.

Abstract:
Objective: To investigate the correlation between maternal glyco-lipid metabolic markers and the triglyceride-glucose index (TyG) during mid-to-late pregnancy and the occurrence of macrosomia in gestational diabetes mellitus (GDM). Methods: Based on a GDM cohort, strict inclusion and exclusion criteria were applied to select mothers who underwent cesarean section at the Nanjing Maternity and Child Health Hospital from January to August 2022. Participants were divided into three groups based on the presence or absence of GDM and neonatal birth weight: normal control group (NC, n = 23), GDM without macrosomia group (GDM-N, n = 23), and GDM with macrosomia group (GDM-M, n = 23). General information and glyco-lipid metabolic markers during mid-to-late pregnancy were collected from the three groups. The TyG index and the homeostatic model assessment of insulin resistance (HOMA-IR) were calculated. Spearman correlation analysis and linear regression models were used to analyze the relationship between maternal indi

Abstract:
Heart failure is a detrimental consequence of various cardiac diseases, with its pathological basis being the progressive interstitial fibrosis-induced cardiac remodeling. Fibroblasts mediate and activate fibrosis to generate extracellular matrix, and excessive activation leads to the accumulation of matrix proteins, ultimately resulting in pathological fibrosis and organ damage. Thyroid hormone plays a crucial role in regulating the cardiovascular system, while subclinical and overt thyroid disorders impact cardiac fibrosis through a series of pathological mechanisms. Conversely, thyroid hormone replacement therapy has been considered for safeguarding cardiac function; however, comprehensive investigations on the effects of thyroid hormones on cardiac remodeling and fibrosis are lacking. The primary objective of this review is to provide an overview of current research on thyroid hormones and their association with cardiac fibrosis.

Abstract:
Objective: To investigate the correlation between imaging phenotypes of cervical cancer (CC) and various clinical and histopathological characteristics. Methods: The MRI radiomics features, along with clinical and histopathological characteristics of 164 patients with CC were collected retrospectively from July 2019 to December 2023. All patients were divided into two clusters by consensus clustering based on the radiomics features. The clinical and histopathological characteristics were compared between groups. Results: Clustering analysis based on tumors showed that compared with cluster 1, cluster 2 was associated with a higher correlation with advanced postoperative FIGO stage [IIA or later: 56/92 (60.9%) vs. 22/72 (30.6%), P=0.001], lymph node metastasis [30/92 (32.6%) vs. 9/72 (12.5%), P=0.002], larger tumor diameter in three dimensions (short diameter: 28.38 ± 9.73 mm vs. 16.67 ± 6.32 mm, long diameter: 34.34 ± 9.72 mm vs. 21.02 ± 7.39 mm, height: 29.92 ± 10.61 mm vs. 18.93 ± 8.01 mm, all P<0.001) and deeper stromal invasion [>2/3: 62/92 (67.4%) vs. 26/72 (36.1%), P<0.001]. Clustering analysis based on lymph nodes showed that difference between two clusters in short axis, long axis, short-to-long axis ratio, border, signal and metastasis was not statistically significant. Conclusion: Associations between radiomics features and clinical and histopathological characteristics of patients with CC could be identified by consensus clustering based on multiparametric MRI-based radiomics, suggesting possibilities for preoperative risk stratification.

Abstract:
Purpose: To develop and validate a radiomics nomogram based on intratumoral and peritumoral multiparametric MRI for preoperative prediction of N2-3 stage axillary lymph node (ALN) in invasive breast cancer. Methods: We retrospectively analyzed 320 invasive breast cancer patients (training: n=224; validation: n=96) who underwent pre-treatment breast MRI from January 2018 to December 2019. Pathological ALN metastases < 4 or ≥4 differentiated N0-1 and N2-3 stage ALN groups. Radiomics features associated with ALN stage were selected from five MRI sequences in three regions (intratumor, peritumor, and intratumor+peritumor), and Random Forest (RF) built three radiomics models and calculated the radiomics signature (Radscore), respectively. Univariate and multivariate logistic regression identified clinical parameters related to N2-3 stage ALN, and then constructed a clinical model. Features from the optimal radiomics model and clinical model were integrated to build a combined model and visualized as a nomogram. Using the receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA), the predictive performance and clinical usefulness of each model were assessed and compared. Results: The Intra&Peri- (intratumor + peritumor) model performed best among the three radiomics models, with an AUC (area under the curve) of 0.911 and 0.858 in the training and validation datasets, respectively. The nomogram integrating Intra&Peri- radiomics features and clinical features (i.e., peritumoral edema and lesion enhancement pattern) had the best predictive efficacy of N2-3 stage ALN among all models, with an AUC of 0.923 and 0.892 in the training and validation datasets, respectively. Calibration curves showed that the predicted values of the nomogram were in good agreement with the actual observed values. DCA demonstrated that the high clinical utility of nomogram. Conclusions: A nomogram constructed by multiregion multiparametric MRI radiomics features and clinical features has high value for personalized prediction of N2-3 stage ALN in invasive breast cancer.

Abstract:
Objective: This study aims to explore the expression of Structural Maintenance of Chromosome 1A (SMC1A) in breast cancer, and analyze its correlation with clinical pathologic features and its influence on apoptosis in breast cancer cells. Methods: The study first analyzed the expression differences of SMC1A mRNA in breast cancer and healthy breast tissues and their prognostic significance using The Cancer Genome Atlas (TCGA) database. It then involved collecting tumor and adjacent non-tumor tissue samples from 48 breast cancer patients at the First Affiliated Hospital of Nanjing Medical University from January to December 2023. We utilized real-time quantitative polymerase chain reaction (RT-qPCR) and immunohistochemistry (IHC) to assess SMC1A expression and its correlation with clinical pathologic traits. Additionally, by downregulating SMC1A expression in the MCF-7 breast cancer cell line, apoptosis-related protein changes were recorded. Results: Analyses showed a significant increase in SMC1A mRNA levels in breast cancer tissues compared to normal tissues, which also correlated with poorer cancer prognosis. Clinical verification indicated a higher expression of SMC1A in cancer tissues than in adjacent non-tumor tissues, correlating with TNM stage, lymph node involvement, and degree of pathological differentiation. Downregulation of SMC1A via siRNA1 in MCF-7 cells notably increased Cleaved-caspase3, Cleaved-caspase9, and BAX levels and decreased BCL2 levels. Conclusion: SMC1A is overexpressed in breast cancer tissues, correlating with disease progression and pathological differentiation. Early mechanistic investigations indicate that reducing SMC1A may promote apoptosis in breast cancer cells, suggesting its regulatory role could be critical in mitigating breast cancer progression.

Abstract:
As a long-term complication of cesarean section, abnormal menstrual patterns and chronic pelvic pain caused by cesarean scar diverticulum (CSD) seriously impacted patients' quality of life. With the adjustments of China's fertility policy, secondary infertility caused by CSD had garnered more attention from scholars. However, no unified standard of diagnosis and treatment for CSD was identified till now. Surgical treatment was considered to be the primary option for patients with fertility requirements, but the specific selection criteria of surgical procedures and the impact of different surgical procedures on subsequent fertility were still controversial. Here, we summarized recent research results of domestic and foreign scholars on CSD over the past 5 years and provided a review of the factors contributing to the formation, diagnosis, and treatment options of CSD, in order to offer a viable references for optimizing clinical strategy for CSD.

Abstract:
Cardiolipin, a lipid crucial for the preservation of mitochondrial function, undergoes perpetual remodeling to adapt to the fluctuating energy requirements of organs and tissues under both physiological and pathological states. A reduction in cardiolipin levels has been linked to the pathogenesis of a multitude of diseases, encompassing cardiomyopathy, Parkinson’s disease, and age-related sarcopenia. Notably, physical exercise has been shown to enhance cardiolipin levels across various tissues, thereby fortifying the body's defense against the detrimental effects of a spectrum of chronic diseases on overall health. In this review, we explore recent advancements in understanding cardiolipin remodeling in response to both exercise and disease states, elucidating the interplay between mitochondrial biogenesis and cardiolipin biosynthesis in orchestrating mitochondrial function, thereby facilitating adaptations to the metabolic demands posed by physical activity and pathological conditions.

[Abstract] (87) [HTML] (0) [PDF 0.00 Byte] (0)

Abstract:
Thyroid hormones (THs) have an important influence on metabolism, growth and energy expenditure in the human body and also play a key role in intestinal function. The thyroid gland mainly produces the thyroid prohormone tetraiodothyronine (T4) and a small amount of the active hormone triiodothyronine (T3).T4 is converted to T3 in peripheral tissues, which influences cellular function by regulating gene expression through binding to nuclear receptors. Thyroid hormones are important for the proliferation and differentiation of intestinal epithelial cells, maintenance of the intestinal barrier, intestinal immune function, and regulation of the intestinal microbiota. Altered intestinal function affects thyroid function, and the balance of intestinal flora is critical for thyroid hormone metabolism. Thyroid hormones maintain intestinal health by regulating the function of intestinal epithelial cells and stem cells, and influence the occurrence and development of intestinal-related diseases.

[Abstract] (213) [HTML] (0) [PDF 0.00 Byte] (0)

Abstract:
Heterogeneous nuclear ribonucleoprotein F (HNRNPF) is a widely expressed RNA-binding protein primarily localized in the nucleus. It plays a crucial role in the maturation of mRNA precursors, facilitating their conversion into functional mRNAs through the recognition and binding of specific RNA sequences. Additionally, it regulates mRNA nuclear transport, enhances expression stability, and influences the transmission of tumor-related signaling pathways. HNRNPF exhibits abnormal expression in various malignant tumors and is strongly correlated with a poor prognosis. It actively participates in crucial biological processes including tumor cell proliferation, invasion, and metastasis, thereby potentially serving as both a therapeutic target and a clinical prognostic marker. This paper aims to conduct a systematic review of the molecular structure, molecular function, expression patterns, and prognostic implications of HNRNPF in malignant neoplasms, along with its associated mechanism of action. The ultimate objective is to generate novel insights for the diagnosis, treatment, and prognosis of malignant neoplasms.

Abstract:
Gastric cancer is closely related to the reprogramming of the tumor microenvironment, but the complexity and heterogeneity of the tumor microenvironment presents a significant challenge to the development of individualized and precise diagnostic and treatment strategies for gastric cancer. Studying the reprogramming process of tumor microenvironment, single-cell sequencing technology can depict the “landscape” of the gastric cancer tumor microenvironment at the single-cell level, explore the interactions between cell subtypes and their components, reveal the novel immune mechanisms by which the tumor microenvironment regulates the progression and metastasis of gastric cancer, explore the molecular mechanism of chemo-resistance in the tumor microenvironment of gastric cancer, identify the potential immunotherapy targets for gastric cancer within the tumor microenvironment，and provide a new prediction method for the prognosis of gastric cancer. This will provide more comprehensive and precise evidence for the study of origin, pathogenesis, progression, and immune tolerance in gastric cancer. The following paper reviews the application of single-cell RNA sequencing technology in the reprogramming of the tumor microenvironment in gastric cancer, and attempts to provide new ideas for the precise diagnosis and treatment of gastric cancer.

Abstract:
Chronic kidney disease (CKD) is a common chronic disease, which is characterized by structural defects and dysfunction in the kidney. The incidence of cognitive dysfunction in CKD patients is significantly higher than that in the general population. Cognitive dysfunction seriously affects the quality of life and therapeutic treatment of CKD patients. In recent years, significant progress has been made in research on the mechanisms and treatments of cognitive impairment induced by CKD. The risk factors of CKD induced cognitive dysfunction include vascular damage, uremic toxins, metabolic acidosis, hemodialysis, and these factors are interwoven with complex mechanisms of renal-brain crosstalk. The current treatments for CKD induced cognitive dysfunction mainly rely on drug therapy, combined with other non-drug therapeutic approaches, such as cognitive rehabilitation training and non-invasive brain electrophysiological stimulation, aiming to achieve optimal therapeutic effects. This review will focus on the research progress of the mechanisms and treatments of cognitive impairment induced by CKD, providing a basis for the early identification, prevention, and treatment of cognitive dysfunction. In the future, studies will continue to explore the pathogenesis of CKD induced cognitive impairment, aiming to provide more effective treatment strategies for clinical practice and improve the quality of life and prognosis of patients.

Abstract:
Abstract: Objective To get DNA aptamers binding to different subtype of breast cancer tissue and cells. Methods A random double-stranded DNA (dsDNA) pool was established by PCR, and single-stranded DNA (ssDNA) library was separated from dsDNA pool by coated Sepharose. Based on subtractive cell-SELEX, in vitro cultured breast cancer cells, MCF-7 and MDA-MB-231, were alternately used as positive screening target while normal mammary gland cell MCF-10A as negative. The effect of PCR amplification and the recovery of aptamer were confirmed by agarose electrophoresis. The PCR conditions were optimized through experiments of temperature gradient while the affinity of aptamers for target cells was monitored by using flow cytometry (FCM). Cloning and sequencing of aptamers were carried out by conventional molecular biology techniques. The aptamers were preliminarily screened by sequence analysis, and DNA aptamers were selected by flow cytometry, laser confocal and immunofluorescence staining. Results A random ssDNA library was successfully established and the screening conditions of SELEX were optimized. Specific DNA aptamers for MCF-7 and MDA-MB-231 cells were got after 20 runs’ tandem crossed cell-SELEX. Of 100 positive sequenced clones, 72 aptamers were identified. Accurate alignment of Blastn implied that not any similar sequence to 72 submitted aptamers was found in NCBI data bank. Five aptamers were preliminarily screened by sequence analysis, and two aptamers which could bind to breast cancer subtype tissue cells were obtained by optimization experiment. Conclusion By using tandem crossed cell-SELEX introduced in this article, DNA aptamers of broad-spectrum combing with clinical breast cancer subtypes can be obtained in a short time, and it is possible to explore the targeted drug delivery system of breast cancer.

Abstract:
Objective To investigate the association between angiotensin (including angiotensin Ⅰ, angiotensin Ⅱ and angiotensin 1-7) and its converting enzyme (including angiotensin converting enzyme and angiotensin converting enzyme 2) and cognitive and motor impairments in Parkinson's Disease (PD). Methods The 200 patients' cognitive and motor functions were evaluated by collecting medical history, using Montreal cognitive assessment (MoCA), Mini-mental State Examination (MMSE) and other scales to assess cognitive function, and using the International Movement Disorders Association Parkinson's Disease Score scale to assess motor symptoms. Serum samples were collected, ACE, ACE2, AngI, AngII, Ang(1-7) and other indicators were detected by enzyme linked immunosorbent assay (ELISA) method, and PD cognitive and motor disorders were predicted by random forest model. Results Based on ACE, AngI, AngII, Ang1-7 and age, the predictive model of PD cognitive impairment on the accuracy of the validation set is 0.847, under ROC Curve and the coordinate axis of Area (AUC) value is 0.909. Based on the ACE, AngI and prediction model of PD dyskinesia Ang1-7 building on the validation set the AUC value is 0.618. Patients with early versus late dyskinesia showed statistically significant differences in ACE, AngI, AngII, and Ang1-7 levels regardless of the presence or absence of cognitive impairment. Conclusion The difference of renin-angiotensin system, especially ACE and AngI, in PD cognitive and motor disorders suggests that it may play a key role in the progression of PD disease. The random forest model performed well in predicting PD cognitive impairment and was helpful in early identification of PD patients with cognitive dysfunction. The potential of RAS components as PD biomarkers and therapeutic targets should be further investigated in the future to provide more comprehensive treatment strategies.

Abstract:
Objective: To analyze the risk factors of postoperative pulmonary complication (PPC) in patients undergoing the surgery of thoracoscopic pulmonary nodules in the Rapid Rehabilitation Care Unit. Methods: The clinical data of 624 patients who underwent the surgery of thoracoscopic pulmonary nodules for the first time in the Rapid Rehabilitation Care Unit were retrospectively analyzed. According to whether PPC occurred within 1 month after discharge, the patients were divided into two groups: PPC group and non-PPC group. Through multivariate logistic regression analysis, independent risk factors were screened to construct a nomogram prediction model and internal verification was performed. Results: PPCs occurred in 209 patients (33.5%). Multivariate logistic analysis showed that long days of thoracic drainage tube placement (OR=1.478, 95%CI:1.043-2.094), large drainage volume on the first day after surgery (OR=1.008, 95%CI:1.006-1.011), malignant pathological results (OR=1.564, 95%CI: 1.037-2.359) were independent risk factors for PPCs. The area under the ROC curve of the prediction model was 0.716 (95%CI:0.673-0.760), and the P value of the calibration curve based on the Hosmer-Lemeshow test was 0.105, suggesting that the discrimination and calibration of the prediction model were good. Conclusion: The days of postoperative chest drainage tube placement, the drainage volume on the first day after surgery and the pathological results are independent risk factors for PPC in patients undergoing the surgery of thoracoscopic pulmonary nodules in the Rapid Rehabilitation Care Unit. The prediction model constructed according to it has good discrimination and calibration, which can provide individualized basis for the prevention and treatment of PPC after VATS.

Abstract:
Objective: A nomogram model is developed based on ultrasound features to provide imaging evidence for enhanced clinical assessment of axillary lymph node metastasis in patients with lateral quadrant breast cancer. Methods: We retrospectively analyzed ultrasonographic features of axillary lymph nodes and primary tumors, which were confirmed by pathology, in patients diagnosed with breast adenocarcinoma. Univariate and multivariate logistic regression analyses were performed to identify risk factors for lymph node metastasis, and a nomogram model was constructed to assess the presence of axillary lymph node metastasis. P value less than 0.05 indicated statistically significant differences. Results: The study cohort comprised 127 patients with breast cancer, of which 54 cases were classified as positive group for axillary lymph node metastasis and 73 cases were classified as negative group for without axillary lymph node metastasis. Multivariable logistic regression analysis revealed that tumor spiculated margins (OR=4.16, 95% CI: 1.25-13.79, p=0.020) and unclear lymphatic gate structure (OR=19.20, 95% CI: 1.98-186.36, p=0.011) independently contributed to the risk of axillary lymph node metastasis in lateral quadrant breast cancer patients. Furthermore, a nomogram model was developed to predict axillary lymph node metastasis in lateral quadrant breast cancer cases. The receiver operating characteristic curve (ROC) demonstrated an area under the curve (AUC) of 0.74 (0.62-0.86 ) for the training set and an AUC of 0.73(0.62-0.84 )for the validation set. Hosmer-Lemeshow test results indicated no significant deviation from goodness-of-fit for both the training set and validation set with p-values of p = 0 .570 and p = 0.552 respectively. Conclusion: Ultrasound plays a valuable role in the assessment of axillary lymph node metastasis in preoperative lateral quadrant breast cancer. Our logistic regression-based nomogram model is both secure and dependable, making it an exceedingly practical tool.

Abstract:
Objective: To investigate the alterations in surface electromyography (sEMG) of the tibialis anterior and gastrocnemius muscles during straight-line walking in Parkinson's disease (PD) with freezing of gait (FOG), and their correlations with clinical features. Methods: Twelve PD patients with FOG, 13 PD patients without FOG, and 11 healthy controls (HCs) underwent clinical assessments, gait kinematics acquisition, and sEMG evaluations during straight-line walking. The sEMG signal characteristics of the severely affected tibialis anterior and medial head of the gastrocnemius muscles during different phases of the gait cycle were analyzed using the normalized root mean square (RMS) and co-activation ratio. Additionally, the correlations between sEMG alterations and clinical features were explored. Results: In comparison with HCs and PD patients without FOG, PD patients with FOG demonstrated notable deceleration in gait speed, reduction in stride length, diminished swing phase, and increased gait variability (p < 0.05). During the single support phase, FOG patients exhibited decreased normalized RMS of the tibialis anterior compared to HCs (p < 0.05). In the pre-swing phase, the normalized RMS of the tibialis anterior was significantly lower in PD patients with FOG than those without FOG (p < 0.01), while PD patients without FOG showed elevated normalized RMS of the tibialis anterior compared to HCs (p < 0.01). Furthermore, the normalized RMS of the gastrocnemius muscle decreased during the pre-swing phase for FOG patients when compared to those without FOG and HCs (p < 0.05). Additionally, the co-activation ratio of the tibialis anterior and gastrocnemius muscles was reduced during the swing phase in FOG patients compared to patients without FOG (p < 0.05). Finally, significant correlations were identified between the normalized RMS of the gastrocnemius muscle during the pre-swing phase and FOG severity (r = -0.758, p = 0.007), co-activation ratio during the swing phase and stride length variability (r = 0.716, p = 0.013) in PD individuals with FOG. Conclusion: The decreased sEMG activity of the tibialis anterior and gastrocnemius muscles during the pre-swing phase, as well as the reduced co-activation ratio during the swing phase, represented significant characteristics in PD patients with FOG. These findings contributed to a deeper understanding of the pathophysiological mechanisms underlying freezing of gait.

Abstract:
Hypertrophic cardiomyopathy (HCM) in children progresses faster and has a higher risk of sudden death, which is a great threat to children's life and health. Presently, echocardiography or magnetic resonance serve as auxiliary diagnosis, but these methods lack the capability to detect the disease at an early stage. Studies have found that mutations in cardiac myosin?binding protein-C (cMyBP-C) gene are closely related to HCM. Exploring the relationship between cMyBP-C and HCM can provide guidance for early diagnosis and treatment of HCM in children, ultimately improving prognosis. This article presents a comprehensive overview of cMyBP-C, including its molecular structure, physiological functions, relationship with HCM, as well as the diagnostic potential of S‐Glutathionylated cMyBP‐C, the therapeutic potential of myocardial myosin ATPase inhibitors, and the gene therapy.

Abstract:
Objective： The effect of COVID-19 infections on detrusor contractility in patients with benign prostatic hyperplasia (BPH) was investigated using ultrasonography video urodynamics studies (SVUDS). Methods：The clinical dataset, including general condition, inflammatory indexs, and SVUDS parameters, of 124 BPH patients with or without COVID-19 infection admitted to the Second Affiliated Hospital of Guilin Medical University and Shaoyang Central Hospital between Jan 2023 and June 2023 were retrospectively reviewed. Those patients were divided into COVID-19(+) and COVID-19(-) group according to the results of COVID-19 nucleic acid detection and clinical data over mentioned were compared between two groups. The correlation between inflammatory indexs and non-invasive SVUDS parameters and detrusor contractility in BPH patients of COVID-19(+) group were analyzed. Results：The serum level of CRP and IL-6 of BPH patients in COVID-19 (+) group were significantly higher than that of COVID-19 (-) group, whereas no significant differences in age, IL-1β, PSA, fPSA, fPSA/PSA, PV, PSAD, IPP, Qmax, URA, BOOI, footpoint, and curvature were found between two groups. Significant thicker BWT, larger PVR，and lower value of detrusor contractility indexs, including Pdet.max, Pdet.Qmax, BCI, and WF?max, were discerned in BPH patients of COVID (+) group compared to that of COVID (-) group. The negative correlation between BWT and WF?max, PVR and BCI, and PVR and WF?max was found in BPH patients of COVID-19 (+) group. Conclusions：COVID-19 might aggravate detrusor underactivity (DU) in BPH patients, resulting to increased PVR even urinary retention, which may be one urodynamic features of long-COVID in those patients.

Abstract:
Objective: To explore the risk factors for chronic pain after single-port video-assisted thoracic surgery (VATS), establish the predictive model and validate it. Method: A retrospective analysis was conducted on 302 patients who underwent single-port thoracoscopy surgery at Nanjing Chest Hospital from January 2023 to June 2023, clinical data of patients were collected using a numerical rating scale（NRS） assessed the degree of pain in patients three months after surgery and divided them into a pain group and a non pain group. Randomly divided into a training set (n=214) and a validation set (n=88) according to a 7:3 ratio, and single factor analysis was performed on the training set.Logistic regression analysis is used to establish a predictive model based on the receiver's work characteristics. Operator characteristic (ROC) curve evaluation model discrimination, calibration curve evaluation model consistency, decision curve analysis (DCA) evaluate the clinical value of the model, and verifying the model in the validation set. Result: Multivariate analysis showed that age (OR=0.925, 95% CI=0.872-0.981, P=0.009), postoperative closed chest drainage time (OR=1.273, 95% CI=1.018-1.591, P=0.034), C-reactive protein value (CRP) on the first day after surgery (OR=1.090, 95% CI=1.030-1.153, P=0.003), and NRS score on the first day after surgery (OR=3.060, 95% CI=1.879-4.981, P<0.001) were independent risk factors for chronic pain after single-port thoracoscopy. Based on this, a prediction model was constructed, with an area under the ROC curve of 0.871 (95% CI=0.799-0.943) and a maximum Yoden index corresponding to 0.195. (0.856, 0.765). With a Bootstrap sample of 1000 times, the predicted risk of chronic pain by the calibration curve was highly consistent with the actual risk. The DCA curve indicates positive returns at all predicted probabilities, indicating good clinical value. Conclusion: After single-port video-assisted thoracic surgery, patient age,time of closed thoracic drainage after surgery, CRP value on the first day after surgery, and NRS score on the first day after surgery are all risk factors for chronic postoperative pain. This prediction model is helpful in accurately predicting chronic postoperative pain and has good clinical application value.

Neurological diseases have always been a major challenge in the field of medicine, and the role of macrophage polarization in them has attracted much attention in recent years. Macrophages have different polarization states, including M1 type and M2 type, which play a key role in the occurrence and development of neurological diseases. In neuroinflammation, M1-type macrophages may exacerbate damage, while M2-type macrophages contribute to tissue repair and nerve regeneration. Studies have found that the imbalance of macrophage polarization is closely related to a variety of neurological diseases, such as Alzheimer's disease, multiple sclerosis, and traumatic brain injury. In response to this phenomenon, some progress has been made in drug research, and new drugs are designed to regulate the polarization of macrophages to reduce inflammation and promote nerve repair. Some drugs regulate the polarization of macrophages by inhibiting specific signaling pathways, while others work by targeting cytokines or receptors. However, there are still many challenges in the current research, such as the safety and effectiveness of the drug, and the complexity of the mechanism of action. This paper summarizes the different polarization phenotypes and main functions of macrophages stimulated by different microenvironmental signals, and focuses on the role of macrophage polarization in nervous system diseases and clinical disease treatment strategies targeting macrophage polarization, which brings new hope for the treatment of nervous system diseases.

Abstract:
Obstructive sleep apnea (OSA) is a common disease, the prevalence of which is increasing year by year, and the nocturnal intermittent hypoxia triggered by it is closely related to a variety of adverse health outcomes, therefore, exploring simple and reliable indicators for the assessment of nocturnal intermittent hypoxia has been a hotspot in recent years. In this paper, we summarise the different current methods of assessing indicators related to nocturnal intermittent hypoxia, including single assessment indexes characterising the frequency (oxygen desaturation index), duration (Time below 90% saturation, Saturation Impairment Time, etc.)、and magnitude (minimum of SpO2 values、magnitude of decrease in oxygen saturation, etc.) of intermittent hypoxaemia, and comprehensive assessment indexes (hypoxic burden, hypoxic burden index, hypoxic load, sleep breathing impairment index, etc.) and are reviewed.

Abstract:
Objective: To detect the expression of sterile alpha motif domain-containing protein 13 (SAMD13) in glioma tissues and cells, and to explore the effect of SAMD13 expression on the proliferation and invasion of glioma cells and its regulatory mechanism. Methods: The expression and prognosis correlation of SAMD13 in glioma patients was analyzed using GEPIA database. The expression of SAMD13 in glioma cells (U373, U87 and U251) was examined by RT-PCR and Western blot. SAMD13 overexpressing plasmid (pIRES2-SAMD13) and SAMD13 shRNA plasmid (shSAMD13) were constructed and transfected into U373 cells, and then the effects of SAMD13 overexpression and silencing on cell proliferation and invasion as well as Akt1, ERK1/2 and STAT3 expression and phosphorylation were determined by Western blot, CCK-8 and Transwell experiments. U373 cells were treated with pIRES2-SAMD13 and ERK1/2 inhibitor (U0126) together, and then the cell proliferation and invasion were examined by CCK-8 and Transwell experiments. Results: SAMD13 expression was increased in glioma patients and was closely correlated with prognosis. SAMD13 was also expressed in U373, U87 and U251 glioma cell lines, with U373 cells being the most significant. SAMD13 overexpression by pIRES2-SAMD13 increased the proliferation and invasion of U373 cells, and SAMD13 knockdown by shSAMD13 decreased the proliferation and invasion of U373 cells. Additionally, SAMD13 overexpression and knockdown increased and decreased ERK1/2 phosphorylation, but had no significant effects on Akt1 and STAT3 phosphorylation. Furthermore, ERK1/2 inhibitor could reduce the proliferation and invasion of U373 cells induced by SAMD13 overexpression, but had no significant effects on SAMD13 expression. Conclusion: SAMD13 is highly expressed in glioma tissues and cells, and up-regulated SAMD13 activates ERK1/2 and enhances cell proliferation and invasion of glioma cells.

Abstract:
Objective: To investigate the effects of 4-Hydroperoxycyclophosphamide (4-HC), an in vitro activated metabolite of cyclophosphamide, on functional damage to the human ovarian granulosa cell line SVOG, as well as its potential mechanisms. Methods: Human ovarian granulosa cells were treated with 0.2 μM, 2 μM, and 10 μM of 4-HC for 24 h, 48 h, and 72 h, respectively. The cell viability of each group was assessed by the CCK-8 assay to determine the appropriate time and concentration for constructing an injury model. Changes in mitophagy flux were evaluated using Western blotting (WB) and real-time quantitative polymerase chain reaction (RT-qPCR). Transmission electron microscopy was used to observe mitochondrial changes in both the normal and 4-HC-injured groups. RT-qPCR was used to assess the expression of P53-related genes, while immunofluorescence was employed to detect the expression levels of P53 protein, Parkin protein, and the mitochondrial outer membrane protein TOMM20. Results: A model of in vitro injury to human ovarian granulosa cell line SVOG was successfully constructed using 2 μM 4-HC treatment for 48 h. In the 4-HC-injured SVOG cells, mitophagy flux was inhibited, and abnormal mitochondrial morphology was observed, with an increase in damaged mitochondria. P53 expression was significantly elevated in the 4-HC-injured SVOG cells. Additionally, there was an increase in cytoplasmic P53 and Parkin protein interaction, while the binding of TOMM20 and Parkin proteins was suppressed in the 4-HC-injured cells. Conclusion: In vitro, 4-HC may lead to human ovarian granulosa cell damage by inhibiting mitophagy of damaged mitochondria through the P53-Parkin pathway.

Abstract:
Objective: To exploring the clinical efficacy and safety of vericiguat in combination with the "new quadruple" for treating heart failure caused by dilated cardiomyopathy (DCM). Methods: Between December 1, 2022 and February 1, 2024, a total of 43 patients with heart failure resulting from dilated cardiomyopathy were consecutively recruited from the outpatient clinic and inpatient wards of the Cardiology Department at the First Affiliated Hospital of Nanjing Medical University. Among them, 33 were male and 10 were female, ranging in age from 30 to 76 years old, with a mean age of 46.7 years. Before enrollment, the patients' LAD, LVEF, LVEDD, NT-proBNP, liver and kidney function electrolytes, and Minnesota Heart Failure Life Quality Scale (MLHFQ) and 6MWT were measured. Patients with heart failure with reduced ejection fraction (HFrEF, LVEF ≤ 40%) and heart failure with mildly reduced ejection fraction (HFmrEF, LVEF 41% ~ 49%) were treated with vericiguat combined with "ARNI, BB, MRA, SGLT2i” new quadruple therapy. Patients with heart failure with preserved ejection fraction (HFpEF, LVEF ≥ 50%) are treated with vericiguat combined with "ARNI, BB, SGLT2i". The above indicators were rechecked after three months of treatment, and the LVEF, LVEDD, NT-proBNP, liver and kidney function, electrolytes and MLHFQ of the patients before and after treatment were compared. Results: For all DCM patients with heart failure, comparison after three months of treatment: LAD（41.37±6.97mm vs. 39.30±5.19, P<0.01）；LVEF（41.02%±10.33% vs. 46.43%±10.74%, P<0.01）；LVEDD（61.40±7.65mm vs. 58.56±7.03mm, P<0.01）；NT-proBNP（2003.59±2279.53ng/L vs. 808.86±1306.98ng/L, P<0.01）；MLHFQ（47.79±9.67vs. 34.86±8.94, P<0.01）；6MWT（348.85 ± 82.43 vs. 401.76 ±95.56, P<0.01）. There was no significant difference in liver and kidney function and electrolytes between patients before and after treatment. Further subgroup analysis showed that Vericiguat combined with "ARNI, BB, MRA, SGLT2i" improved the LVEF and reduced NT-proBNP levels in patients with HFrEF, HFmrEF or HFpEF heart failure caused by DCM. and improved patients' quality of life scores. Conclusion: Vericiguat combined with the "new quadruple" drugs has a significant therapeutic effect on patients with heart failure caused by DCM and the effect is obvious after three months’ treatment. This study provides potential data support and guidance for the treatment of DCM patients with clinical heart failure.

Abstract:
[Abstract] Objective: To evaluate the potential of using a multi-point wearable device in facilitating early diagnosis of Parkinson’s disease (PD) with the unified Parkinson′s disease Rating Scale III (UPDRS III). Methods: A total of 54 subjects were recruited in this study. They were divided into the early PD group (n=30, UPDRS III<30 points) or the normal control group (n=24).Each subject wore a multi-point wearable device when performing the standard actions required by the UPDRS III. Ten inertial sensors were employed to collect motor parameters including the angular speed and acceleration data from the subject’s chest，waist, knee joint, elbow joint, ankle joint, and foot. We compared the motor parameters between the two groups, and applied support vector machine and ten-fold cross-validation to calculate the model that could distinguish between the two groups with its diagnostic potentials. Results: There were significant statistical differences in the motion parameters of wearable devices in the early PD group and the normal control group after completing the specified actions of UPDRS III (P<0.05).The accuracy of speech action between the two groups was the highest, reaching 0.906. Compared with the upper body movement group, the lower body movement group and the whole body movement group had higher consistency, sensitivity and accuracy, and could specifically identify the movement disorders of early PD patients.Conclusion: Multi-point wearable devices can objectively evaluate the characteristics of movement disorders in early PD patients, and can be used as a tool for auxiliary diagnosis and quantitative evaluation of early PD.

Abstract:
Objective: The neutrophil to lymphocyte ratio (NLR) has been proposed as an inexpensive and widely available marker in many diseases. In this study, we aimed to assess the value of NLR to predict the severity and pancreatic necrosis (PN) in acute biliary pancreatitis (ABP). Methods: 290 patients with ABP were enrolled in this study. The blood samples were collected within 24 hours after AP onset. The optimal cut-off value for NLR to predict severe AP (SAP) and PN was determined by receiver operating characteristic (ROC) curve analysis. ABP model was induced by taurocholic acid sodium in rats. The blood samples and pancreatic tissue samples were collected and we compared NLR in different time points and concentration of taurocholic acid sodium. Results: The area under the ROC curve showed NLR had a predictive performance for SAP (AUC: 0.944, SE: 0.015, 95% CI: 0.915-0.973, p<0.001). The optimal cut-off from ROC curve was 13.38 (sensitivity: 80.0%; specificity: 83.2%). For the prediction of PN, the AUC of NLR was 0.910 (SE: 0.025, 95% CI: 0.861-0.958, p<0.001). The cut-off value of NLR was 9.265 (sensitivity: 97.1%; specificity: 72.7%). In taurocholic acid sodium-induced ABP in rats, the NLR increased significantly and peaked earlier than PN. The NLR was observed to increase along with the increase of the extent of PN. Conclusion: NLR at the initial stage (within 24h after the onset) may serve as a powerful marker for early predicting severity and PN in ABP.

Abstract:
Objective: To investigate the role of the esophageal squamous cancer-specific ultra-conserved cancer/testis (CT)-LINC01424 in esophageal squamous cancer progression. Methods: The TCGA (The Cancer Genome Atlas) and GTEx (Genotype-Tissue Expression) databases were used to screen the long non-coding RNA (lncRNA) with ultraconservative CT properties specific to esophageal squamous carcinoma, and the nucleoplasmic isolation assay and rapid amplification of cDNA end (RACE) were used for the cellular localization and sequence identification of LINC01424.118 pairs of esophageal cancer samples was used for the analysis of prognosis. After knocking down LINC01424 in Eca109 cell line or overexpressing LINC01424 in KYSE410 cell line, the effects of CT-LINC01424 on the esophageal squamous carcinoma was detected by CCK-8 assay, colony assay, Transwell assay, and nude micel assay; further application of MEM (Multi Experiment Matrix) database for downstream gene exploration. Results: An ultraconservative CT-LINC01424 specific for esophageal squamous carcinoma was identified. Analysis of clinical data showed that CT-LINC01424 was significantly associated with poor clinical stage and prognosis of esophageal squamous carcinoma. Knockdown of the expression of LINC01424 inhibited the proliferation and invasion of esophageal squamous carcinoma cells, while overexpression of LINC01424 resulted in the opposite result. Furthermore, the expression of LINC01424 was significantly co-expressed with KNTC1 (Kinetochore Associated 1) gene. Conclusion: LINC01424 is highly expressed in esophageal squamous carcinoma tissues, promotes the proliferation and invasion of esophageal squamous carcinoma cells, and may exert its pro-carcinogenic effects by affecting the expression of KNTC1.

Abstract:
Objective: To investigate the correlation between the expression of integrin binding sialoprotein (IBSP) in glioma and the clinical prognosis of patients and its regulatory effect on tumor cell proliferation, invasion and chemotherapy resistance. Methods: A public database was used to analyze the expression of IBSP in glioma and its relationship with the prognosis of patients. Knockdown and overexpression of IBSP in glioma cells, functional assays to assess cell proliferation, invasion, and chemoresistance alterations. Results: Database analysis showed that the expression level of IBSP in glioma was significantly increased, and the high level of IBSP indicated a poor prognosis. Knockdown of IBSP inhibited glioma proliferation, invasion and chemoresistance, and overexpression of IBSP promoted glioma proliferation, invasion and chemoresistance. Overexpression of IBSP promotes the activation of NF-κB pathway and the expression of downstream genes of NF-κB, which in turn promotes the malignant phenotype of glioma cells. Conclusion: IBSP promotes glioma cell proliferation, invasion and chemoresistance by activating the NF-κB signaling pathway, suggesting that IBSP can be used as a potential therapeutic target for glioma.

Abstract:
[Abstract] Objective To explore the role of microRNA-146a (miR-146a) in hypoxia induced macrophages. Mehhod The expression of miR-146a/TRAF6, inflammatory factors and reactive oxygen species(ROS) in macrophages were determinated under hypoxia-reoxygenation model. Moreover, release of inflammatory factors and ROS were analyzed after mimic or inhibitor of miR-146a. Results We found that the miR-146a levels were obviously decreased in hypoxia induced macrophages, while the expression of TRAF6, inflammatory factors and ROS increased. Overexpression of miR-146a directly decreased TRAF6 expression and reduced the release of inflammatory factors and ROS, however, transfection with miR-146a inhibitor increased the levels of TRAF6 and promoted inflammation response. Conclusion Overexpression of miR-146a attenuates the inflammation response in hypoxia induced macrophages by directly targeting the TRAF6 gene. New treatment strategies targeting miR-146a may help reduce ischemia-reperfusion injury caused by inflammatory cytokines and ROS in macrophages

Abstract:
Objective：To explore the application value of the radiomics models based on T2-weighted imaging (T2WI) and Diffusion-weighted imaging (DWI) in non-invasive preoperative prediction of pituitary adenoma consistency. Methods：The clinical and preoperative MRI data of 108 patients with pathologically confirmed pituitary adenoma were retrospectively analyzed and divided into soft and hard groups based on the intraoperative assessment of tumor consistency by two neurosurgeons. The cases were randomly divided into a training cohort and a validation cohort in a ratio of 7:3.Volume of interest (VOI) were delineated manually on T2WI and DWI images.Radiomics features were extracted by FeAture Explorer software. Unsupervised Feature Selection (UFS) was used to select features. Support vector machine(SVM) was used to conduct the radiomics models.Area under curve (AUC) and calibration curve were used to assess the performance of the models. Results：In the radiomics model based on T2WI combined with DWI，the training cohort to predict pituitary adenoma consistency had an AUC of 0.89.The validation cohort had an AUC of 0.80. Calibration curve showed a good agreement between predicted and actual probabilities. Conclusion: The radiomics model based on T2WI combined with DWI showed good diagnostic performance and was promising in predicting the consistency of pituitary adenoma before surgery.

Abstract:
Objective: To establish and verify the prediction model of activated clotting time (ACT) measured 30 minutes after the first dose of heparin in patients with atrial fibrillation during radiofrequency ablation. Methods: A single-center retrospective study design was adopted. From January 2020 to December 2022, 1090 patients with nonvalvular atrial fibrillation were selected for radiofrequency cardiac catheter ablation with the catheter room of the Department of Cardiology, the First Affiliated Hospital of Nanjing Medical University. Patients were randomly divided into the training set and testing set in a 3:1 ratio. Kruskal-Wallis test and Chi-square test were used to compare baseline characteristics of the training set and testing set. LASSO regression, univariate and multivariate linear regression were used to analyze the independent factors influencing 30min-ACT. Based on this, the prediction model of 30min-ACT with the first dose of heparin during radiofrequency ablation in patients with atrial fibrillation was established and its predictive effect was evaluated. Results: Multivariate analysis of results suggested that stroke history, warfarin, platelet count, prothrombin time, basal ACT, basal ACT2, and first dose of heparin were independent predictors of first dose of heparin ACT during radiofrequency cardiac ablation in patients with atrial fibrillation, and the prediction model based on the constructed histogram had a certain accuracy (training set = 65.9%, testing set = 74.6%) and higher sensitivity (training set = 77.4%, testing set = 83%). Conclusion: Based on stroke history, warfarin, platelet count, PT, baseline ACT, baseline ACT2 and first dose of heparin, the nomogram model can predict the anticoagulant effect of the first dose of heparin in atrial fibrillation patients, 30min-ACT, providing valuable clinical guidance.

Abstract:
Objectives: Elevated serum uric acid (UA) levels may be a risk factor for hypertriglyceridemia (HTG). This study analyzes the relationship between UA levels and HTG using collected clinical data. Methods: The study analyzed clinical data from 11, 206 participants in 2023. Multivariate logistic regression was used to examine the relationship between UA levels and HTG. Generalized linear models, smooth curve fitting, and threshold effect analysis were applied to investigate the nonlinear relationship between UA levels and HTG. Results: The study included 11, 206 participants, divided based on TG levels into HTG group (n=3410) and non-HTG group (n=7796). After adjusting for confounders, the multivariate logistic regression model indicated that increased lnUA was positively associated with HTG risk. In quartile analysis, increases in lnUA were positively correlated with HTG risk; Q1 OR=1.00, Q2 OR=1.557 (95% CI: 1.349, 1.796, P<0.001), Q3 OR=1.977 (95% CI: 1.712, 2.283, P<0.001), and Q4 OR=3.101 (95% CI: 2.672, 3.598, P<0.001), showing a strong positive correlation between lnUA and HTG across all levels. Smooth curve fitting demonstrated a nonlinear relationship between UA levels and HTG. The turning point of the U-shaped association between lnUA and HTG was found at 5.517, with the effect size on the right side being 4.692 (95% CI: 3.747, 5.875) higher than on the left at 2.766 (95% CI: 1.869, 4.094). Conclusion: Serum UA levels are positively correlated with HTG. Given that UA may be a risk factor for HTG, individuals diagnosed with HTG should prioritize the daily management of UA levels.
