[摘 要] 目的:探究血清中程序性细胞死亡因子 4(programmed cell death 4,PDCD4)蛋白水平与急性缺血性脑卒中(acute
ischemic stroke,AIS)患者的神经功能缺损和预后的相关性。方法:回顾性连续纳入2023年6月—2024年3月南通大学第二附
属医院神经内科诊治的 110 例 AIS 患者作为研究对象,根据美国国立卫生研究院卒中量表(national institutes of health stroke
scale,NIHSS)将患者分为轻度神经功能缺损(n=70)和中重度神经功能缺损(n=40)。采用改良 Rankin 量表(modified Rankin
scale,mRS)将患者分为预后良好组(n=69)和预后不良组(n=41)。收集各组患者的人口学资料(年龄、性别、糖尿病病史等)及
临床检验指标(中性粒细胞计数、淋巴细胞计数、中性粒细胞/淋巴细胞比值等)。采用酶联免疫吸附法测定血清PDCD4蛋白浓
度,并分析其与NIHSS评分、mRS评分及炎症指标的相关性。使用Logistic回归分析模型推断AIS患者中重度神经功能缺损和
预后不良发生的危险因素,并通过受试者工作特征(receiver operating characteristic,ROC)曲线来评估血清PDCD4蛋白水平对
预测AIS患者神经功能缺损程度及预后情况的有效性。结果:AIS患者中,中重度神经功能缺损及预后不良者血清PDCD4蛋
白水平显著高于轻度神经功能缺损及预后良好者。血清PDCD4水平与NIHSS评分、mRS评分、降钙素原、超敏C反应蛋白、中
性粒细胞/淋巴细胞比值呈正相关。排除混杂因素的干扰后,PDCD4蛋白水平仍是AIS患者的独立危险因素。ROC曲线显示,
血清PDCD4蛋白水平对AIS患者神经功能缺损程度和预后情况均有较高的预测价值。结论:在中重度神经功能缺损及预后不
良的AIS患者中,血清PDCD4蛋白水平显著升高,且可作为预测AIS患者神经功能缺损程度及预后的独立指标。

[Abstract] Objective:To investigate the relationship between serum programmed cell death factor 4(PDCD4)levels and
neurological deficits as well as prognosis in patients with acute ischemic stroke(AIS). Methods:A retrospective analysis was
conducted on 110 AIS patients admitted to the Department of Neurology,the Second Affiliated Hospital of Nantong University between
June 2023 and March 2024. 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,sex,diabetes history,etc.)and clinical
data(neutrophil count,lymphocyte count,neutrophil⁃to⁃lymphocyte ratio,etc.)of each group of patients were collected. Serum PDCD4
levels were measured using an enzyme⁃linked immunosorbent assay(ELISA),and their correlations with NIHSS scores,mRS scores,
and other inflammatory markers were analyzed. Logistic regression was employed to identify risk factors for moderate ⁃ to ⁃ severe
