    • Effect of Rapamycin on TGF-β1- induced epithelial-mesenchymal transition in LoVo colonic adenocarcinoma cells

      2009, 29(1):15-19. DOI: 10.7655

      摘要 (2694) HTML (59) PDF 856.66 K (3160) 评论 (0) 收藏

      摘要:Objective:To investigate the effect of Rapamycin on epithelial-mesenchymal transition (EMT) of LoVo colonic adenocarcinoma cells in vitro. Methods:Cultured LoVo colonic adenocarcinoma cells were divided into three groups: negative control group, EMT-inducing group (TGF-β1) and EMT-interfering group (TGF-β1 plus Rapamycin). E-cadherin expression in LoVo cells was detected by Western Blot, while the expression of vimentin was evaluated through immunocytochemistry. The Snail mRNA in LoVo cells was examined by RT-PCR. Results: TGF-β1 induced LoVo cell switching from polygonal to spindle-shaped. TGF-β1 enhanced the expression of vimentin, but lowered the level of E-cadherin. In contrast, Rapamycin impaired the transition induced by TGF-β1. Rapamycin dramatically abrogated TGF-β1-induced vimentin expression and restored E-cadherin expression in LoVo cells. Rapamycin significantly repressed the up-regulation of Snail mRNA expression induced by TGF-β1. Conclusion: Rapamycin dramatically abrogated TGF-β1 induced Snail mRNA expression in LoVo cells, hence inhibiting the EMT of these cells in vitro.

      摘要:Objective: To determine epidemiologic features of an Escherichia coli O157:H7 outbreak occurred in Xuzhou, Jiangsu Province, China in 1999, and assess the incidence of E. coli O157:H7 in diarrhea patients and host animals and its relationship with disease onset, and provide a scientific basis for establishing prevention and control strategies. Methods: Epidemiological, microbiological, and molecular methods were performed to identify risk factors and describe the ecology of E. coli O157:H7 in the environment. Results: From May to September, in 1999, 99 cases of E. coli O157:H7 infection were confirmed. Fifty-six patients were enrolled in the case-control study. Bad personal health habits and poor sanitary conditions in the kitchen were associated with increased risks of infection, whereas hand washing was protective. The household survey indicated that residents in the epidemic region during the outbreak had higher than expected rates of diarrhea. The total E. coli O157:H7 carrier rate in the livestock was 12.36% (22/178), specifically 19.15% in cattle, 12.50% in goat, and 11.11% in swine. Numerical analysis of pulsed-field gel electrophoresis (PFGE) profiles divided strains into two clusters with 77.5% homology. One cluster contained 11 strains isolated from diarrheal patients, foods, and animals. The other cluster comprised 10 strains from patients and environment. Conclusions: In a large outbreak of E. coli O157:H7 infection among predominantly elderly residents in Xuzhou, high rates of carriage of E. coli O157: H7 among host animals most likely resulted in contamination of the environment, thereby leading to the outbreak. Effective and preventive control measures should be taken to avoid contamination, including environmental and family health improvement, good personal hygiene, and safe food handling practices.

      摘要:Objective: To evaluate the effects of polymorphisms in TLR7 and TLR8 (as potential candidate genes) on asthma risk and asthma-related phenotypes.Methods: We consecutively recruited 318 unrelated adult asthmatic patients and 352 healthy volunteers from the same area of southeast China. Genotyping of each selected SNP was performed using multiplex PCR in conjunction with tagged array single base extension technology. We conducted case-control and case-only association studies between the selected SNPs in TLR7 and TLR8 and asthma or asthma-related phenotypes.Results: The T allele of rs5935436 SNP in TLR7 was protective from developing asthma in males (adjusted ORs = 0.126, 95% CIs = 0.016-0.995). The CT/TT genotype of rs5935436 was less frequent in female asthmatics with allergic rhinitis (adjusted ORs = 0.18, 95% CIs = 0.04-0.90). The homozygote AA of rs3761623 and GG of rs3764880 were positively associated with lower FEV1% and asthma severity in female asthmatics. These results were confirmed by haplotype analysis.Conclusion: TLR7 and TLR8 polymorphisms may play an important role in the pathogenesis of asthma that is gender-dependent. This could be clinically useful, both for identifying patients at risk of asthma and for preventing its occurrence.

      摘要:Objective: To explore the relationships between the daily total intake of fluoride, dental fluorosis and dental caries. Methods: An epidemiological method was used to investigate the daily total intake of fluoride, dental fluorosis, and dental caries among 236 and 290 children aged 8-13 years in a severe endemic area and in a non-fluorosis control area, respectively. The children were divided into eight subgroups according to each child’s estimated daily total intake of fluoride. The prevalence of dental fluorosis and dental caries in each group was calculated. Results: As expected, elevated levels of fluoride intake were significantly associated with a higher prevalence of dental fluorosis and an increasing amount of more severe defect dental fluorosis. When the daily total F intake was 2.78 mg/child/day, the prevalence of dental fluorosis was nearly 100%, with the prevalence of defect dental fluorosis increasing with increasing fluoride intake. There was also a significant negative (inverse) dose-response relationship between the daily total intake of fluoride and the overall prevalence of dental caries, the prevalence of which decreased when the daily total intake of fluoride increased up to 3.32 mg/child/day. However, at higher levels of daily total intake of fluoride the prevalence of dental caries increased, giving rise to a U-shaped dose-response relationship curve. Conclusion: It is important to monitor total fluoride exposure and protect children from excessive fluoride intake, especially during the years of tooth development.

      摘要:Objective:Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is a common birth defect with unclear etiology. Both genetic and environmental factors may contribute to NSCL/P. Many genes have been identified as candidate genes associated with this disease. Interferon regulatory factor 6 (IRF6) gene and transforming growth factor-a (TGFA) gene seem to be crucial in the predisposition of NSCL/P. Here we evaluated some single nucleotide polymorphisms (SNPs) loci of TGFA and IRF6 genes in Chinese nuclear families consisting of fathers, mothers and affected offspring with NSCL/P.Methods:Fifty patients of NSCL/P were confirmed by the plastic surgeons. They and their parents were included in the study, all with the informed consents. SNPs loci of TGFA and IRF6 genes were analyzed by microarray technology. Some PCR products were randomly chosen and sequenced to check microarray results. The distribution of gene type and allele frequency between patient group and parents group were compared. Then a Haplotype Relative Risk (HRR) and Transmission Disequilibrium Test (TDT) were performed. Results:The sequences of randomly selected PCR products were all consistent with the microarray results. All loci were in Hardy-Weinberg equilibrium. There were no significant differences in the distribution of genotypes and alleles between patients and their parents. Using HRR and TDT analyses the V274I of IRF6 was associated with NSCL/P, while another SNP locus of IRF6 was not. Strong evidence of linkage disequilibrium was found between the 2 SNP loci of TGFA and disease with the HRR analysis, but not with the TDT analysis.Conclusion:Our study confirms the contribution of IRF6 in the etiology of NSCL/P in populations of Asian ancestry. The association of TGFA with NSCL/P requires further research.

      摘要:Objective:To investigate the effects of simvastatin, a 3-hydroxy-3-methylglutaryl coenzyme A(HMG-CoA) reductase inhibitor, on adiponectin and markers of endothelial function in apolipoprotein E -deficient mice at an early stage of atherosclerosis.Methods: Twenty-four 6-week old male apoE-deficient mice were randomly divided into two groups: control group (normal saline) and treatment group (simvastatin (5 mg/(kg·d)). Simvastatin was administered to treatment group mice by gavage and the same volume of normal saline was administered to control group mice by the same method for 4 weeks. Total cholesterol (TC), superoxide dismutase (SOD), malondialdehyde (MDA), and nitric oxide (NO) were measured by biochemical analysis, and adiponectin was measured by an ABC-ELISA method. Results : There was no significant difference in serum TC between control and treatment groups. Compared with the control animals, simvastatin-treated animals exhibited a significant increase in serum levels of adponectin, SOD and NO, and decrease in serum MDA (P <0.01).Conclusion: Simvastatin protects endothelial function by increasing serum adiponectin, which may increase serum SOD and NO, and decrease serum MDA. This study suggests that simvastatin has therapeutic advantages, unrelated to its cholesterol-lowering effect, that are mediated by adiponectin.

    • Induction of interleukin-8 production by angiotensin II in rat vascular smooth muscle cells

      2009, 29(1):50-53. DOI: 10.7655

      摘要:Objective: Interleukin-8 (IL-8) represents the prototypical chemokine that is made by a wide variety of cell types. Previously studies have suggested that angiotensin II (Ang II) is involved in atherogenesis through induction of proinflammatory cytokines such as interleukin-6 or monocyte chemoattractant protein-1 (MCP-1) in vascular smooth muscle cells (VSMCs), while the role of Ang II on IL-8 expression in VSMCs is poorly studied. Methods: In this study, VSMCs were isolated from the thoracic aorta of Sprague-Dawley rats. The expression of smooth muscle α-actin was confirmed by an immunocytochemical method. Semi-quantitative RT-PCR and enzyme-linked immunosorbent assay (ELISA) analyses were conducted to detect IL-8 expression. Results: In the present study we found that Ang II significantly increased the expression of IL-8 both at the mRNA and protein levels in rat VSMCs in a dose- and time-dependent manner. Conclusion: These findings suggested that Ang II may participate in atherosclerosis through induction of inflammatory mediator in VSMCs.

      摘要:Objective: Throughout the world, fetal growth restriction (FGR) is one of the most severe complications occurring during pregnancy. It is subsequently associated with neurologic abnormalities in chldren. Our aim was to investigate the spatial learning and memory ability of rat offspring born with FGR. Methods: A rat model of FGR was constructed using the method of passive smoking. Spatial learning and memory were studied in rat offspring born with FGR by assessing the animals’ performance using the Morris water maze task. Results: At 1- and 2- months of age, both female and male offspring rats showed impairment of performance, while at 4 months of age, only female rats showed impaired performance. The FGR offspring spent a longer time swimming and used inefficient strategies (p<0.05, respectively). However, there were no significant maze performance FGR effects in the 4 month old male rats. In all groups of FGR offspring, irrespective of age or sex, the time spent in the platform quadrant by the rat was significantly less than that in the control group (p<0.05). Conclusion: The Morris water maze performance decreased in rat offspring born with FGR. It is suggested that FGR can cause impairments of spatial learning and memory in young animals.

      摘要:Objective:To investigate the relationship between sleep apnea hypopnea syndrome (OSAHS) and some cardiovascular disorders in adult habitual snorers as well as the effectiveness of nasal continuous positive airway pressure on those with OSAHS. Methods:With the use of polysomnography, 262 adult habitual snorers were examined and divided into the OSAHS group and the Non-OSAHS group (control). Using ambulatory electrocardiogram and blood pressure measurement, daily nocturnal rhythm of blood pressure, hypertension, heart rate variability, some arrythmias and angina pectoris of coronary heart disease were monitored and compared between the two groups, before and after 14 days of treatment with nasal continuous positive airway pressure in the OSAHS group. Results:This study indicated a higher incidence (39.6%) of OSAHS in adult snorers and demonstrated that there was a significantly higher incidence of hypertension, disappearance of the daily nocturnal rhythm of blood pressure, poor effectiveness of nitrate on angina pectoris of coronary heart disease, decreased heart rate variability during sleep, increased arrythmias and lower SpO2 levels in the OSAHS group than in the Non-OSAHS group. After nasal continuous positive airway pressure treatment during sleep, snoring control, significantly higher SpO2 and lower apnea hypopnea indices were achieved in the OSAHS group; heart rate variability and daily nocturnal rhythm of blood pressure returned to normal levels.Conclusion:The results of this research suggested that there was a close relationship between the development of OSAHS and some cardiovascular disorders. Furthermore, nasal continuous positive airway pressure treatment was effective not only on OSAHS but also on coexisting cardiovascular disorders.

      摘要:Objective:To explore the effect of neural histamine in the tuberomammillary nucleus (TM) on neurogenic pulmonary edema (NPE) onset in rabbits and the function of the rostral ventrolateral medulla (RVLM) in the neural histamine modulation of NPE. Methods: NPE was produced by the intracisternal injections of fibrinogen and thrombin. The contents of histamine in the TM and RVLM in rabbits were measured with high performance liquid chromatography (HPLC). Rabbits were placed on a stereotaxic frame and microinjection cannulae were inserted into the TM and RVLM using brain atlas coordinates. Animals were pretreated with R-α-methylhistamine (MeHA) in the TM and chlorphenamine Mmaleate/cimetidine in the RVLM prior to establishing the NPE model. Changes in the lung water ratio and mean arterial pressure (MAP) were recorded, and paraffin sections of lung tissue were observed by light microscope. Results: We found that the contents of histamine (HA) in the TM and RVLM increased significantly with the onset of NPE. Pretreatment with MeHA in the TM and chlorphenamine Mmaleate in the RVLM significantly decreased MAP, and the lung water ratio and histological characteristics of the NPE in the rabbit model. Pretreatment with cimetidine in the RVLM had no effect on NPE.Conculsion:The results suggest that neural histamine in the TM is involved in the onset of NPE, and this effect of neural histamine is mediated by H1 receptor in the RVLM.

      摘要:Objective: This paper was designed to confirm the efficacy of chewing carboxymethyl chitosan (CMCTS)-containing gum in suppressing the growth of oral bacteria when compared to a CMCTS-containing mouth rinse. Methods: Fourteen healthy subjects were recruited from among the staff and students of Qingdao University Dentistry Department. Before the experiments saliva was collected from all subjects and bacteria counts determined. For the gum study, the subjects chewed CMCTS-containing gum for 5 min and then rested for 5 min. When testing the CMCTS mouth rinse, the subjects gargled with 10 mL of solution for 30 s, followed by resting for 9min 30 s. These protocols were repeated five times over a 50 min period on the same day. Post-experiment saliva samples were then collected at the following times: 0, 30 and 60 min.Results: Chewing gum containing CMCTS or rinsing with a CMCTS-containing rinse significantly decreased oral bacteria counts. The total bacteria counts, total Streptococci counts, and mutans streptococci counts of saliva from subjects who chewed CMCTS-containing gum were significantly lower than saliva from subjects in the rinse group in all three sampling periods, except in the case of the total bacteria count in the 60 min samples. Conclusion: CMCTS-containing gum chewing has a greater antibacterial effect than using a CMCTS-containing mouth rinse. The present findings strongly indicate that the application of natural materials such as chitosan and its derivatives is useful for better oral health.

      摘要:Objective: We have explored the role of nuclear factor kappa B (NF-kB) in the pathogenesis of chronic glomerulonephritis, and investigated the effect of rhododendron root on the activation of NF-kB. Methods: Thirty-six Wistar rats were randomly divided into three groups: a control group, a glomerulonephritis model group and a therapy group (glomerulonephritis animals treated with the root of rhododendron). Bovine serum albumin (BSA) nephritis was induced by subcutaneous immunization and daily intraperitoneal administration of BSA. Twenty-four-hour urinary protein and serum creatinine values were measured, and renal pathology was assessed histologically by optical microscopy and electron microscopy. NF-κB activity was determined by an electrophoretic mobility shift assay (EMSA). Results: Compared with the control rats, glomerulonephritis model rats exhibited a significant increase in both 24h urinary protein and serum creatinine, and had abnormal renal histology. The administration of the root of rhododendron ameliorated these changes. NF-κB activity in glomerulonephritis model group was greater than that in rhododendron-treated group, and NF-κB activity was greater in both glomerulonephritis groups than in the control group (P<0.01). Conclusion: These observations suggest that NF-kB plays a role in the pathogenesis of chronic glomerulonephritis, and rhododendron root may attenuate renal damages by downregulating the activation of NF-kB in this model.
