摘 要 目的 探讨老年缺血性脑卒中患者CYP2C19基因多态性对血小板功能、炎症细胞因子的影响,并分析造成患者预后不良
的潜在因素。方法 回顾性收集2024年6月至2025年6月我院收治的接受CYP2C19基因型检测并接受氯吡格雷抗血小板治疗的
老年缺血性脑卒中患者的临床资料。比较不同代谢型患者治疗前后血小板功能指标和炎症细胞因子水平。依据治疗6个月后的
预后情况,将患者分为预后不良组和预后良好组,对其一般资料、代谢型、血小板功能指标以及炎症细胞因子水平进行单因素分
析,将P<0.05的变量和治疗前炎症细胞因子水平纳入多因素Logistic回归分析,筛选造成患者预后不良的独立危险因素;采用多
元线性回归进一步分析代谢型与炎症细胞因子的关系。结果 共纳入老年缺血性脑卒中患者448例;其中正常代谢型162例,中间
代谢型218例,慢代谢型68例,未见快代谢型和超快代谢型。治疗后,正常代谢型组、中间代谢型组和慢代谢型组患者的血小板聚
集率和P选择素、血小板活化复合物1、超敏C反应蛋白(hs-CRP)、白细胞介素1β(IL-1β)、IL-6、肿瘤坏死因子α(TNF-α)水平(慢
代谢型患者的血小板聚集率和P选择素、血小板活化复合物1水平除外)均显著低于同组治疗前,且正常代谢型组上述指标水平均
显著低于同期中间代谢型组、慢代谢型组,中间代谢型组血小板功能指标水平均显著低于同期慢代谢组(P<0.05)。单因素和多
因素Logistic回归分析结果显示,合并高血压、合并糖尿病、代谢型为中间代谢型及慢代谢型是老年缺血性脑卒中患者预后不良的
独立危险因素(P<0.05)。多元线性回归分析结果显示,中间代谢型和慢代谢型组治疗前的血清hs-CRP、IL-1β、IL-6、TNF-α水平
均较正常代谢型组显著升高(P<0.05),且慢代谢型的炎症细胞因子水平升高幅度更大。结论 CYP2C19中间代谢型和慢代谢型
老年缺血性脑卒中患者的血小板抑制效果较差,炎症细胞因子水平较正常代谢型高;CYP2C19基因多态性和合并高血压、糖尿病
可作为预后不良的独立预测指标。

ABSTRACT OBJECTIVE To investigate the influence of CYP2C19 gene polymorphism on platelet function and inflammatory
cytokines in elderly patients with ischemic stroke, and to analyze potential factors associated with poor prognosis. METHODS A
retrospective study was conducted on elderly patients with ischemic stroke admitted to our hospital from June 2024 to June 2025,
who underwent CYP2C19 genotype testing and received antiplatelet therapy with clopidogrel. The levels of platelet function
indicators and inflammatory cytokines before and after treatment were compared among patients with different metabolic
phenotypes. Based on the prognosis at 6 months post-treatment, patients were divided into poor prognosis group and good prognosis
group. Univariate analysis was performed on general data, metabolic phenotype, the levels of platelet function indicators and
inflammatory cytokines. Variables with P<0.05 and the levels of inflammatory cytokines before treatment were included in a
multivariate Logistic regression analysis to identify independent risk factors for poor prognosis. Multiple linear regression was used
to further analyze the relationship between metabolic phenotypes and inflammatory cytokines. RESULTS A total of 448 elderly
patients with ischemic stroke were included; among them, 162 cases were normal metabolic phenotype, 218 were intermediate
metabolic phenotype, and 68 were poor metabolic phenotype. No rapid or ultrarapid metabolic phenotypes were observed. After
treatment, platelet aggregation rate, the levels of P-selectin
