摘要:



文题释义:
缺血性脑卒中:又称脑梗死,是指因脑部血液供应中断或严重减少导致相应区域的脑组织因缺血、缺氧而发生坏死、软化,并产生相应神经功能缺损症状和体征的临床综合征,该病的核心病理生理机制为:血流中断→缺血缺氧→能量代谢衰竭→细胞毒性水肿→细胞坏死/凋亡。
基因多态性:是指在一个生物群体中,同一基因位点上存在2种或2种以上的等位基因或遗传变异,并且其中最常见的等位基因频率不低于1%(通常以1%作为与罕见突变区分的阈值)。

背景:氯吡格雷可用于治疗和预防缺血性脑卒中的复发,然而不同患者对氯吡格雷的代谢可能存在个体差异,其中CYP2C19基因多态性被认为是一个重要的影响因素。
目的:探究缺血性脑卒中患者氯吡格雷代谢相关基因多态性分布情况,并分析与其预后的关系。
方法:选择2023年1月至2024年1月天门市第一人民医院收治的缺血性脑卒中患者70例,男39例,女31例,平均年龄(60.89±4.72)岁,口服硫酸氢氯吡格雷7-14 d后,采集所有患者的空腹静脉血,采用聚合酶链反应-限制性片段长度多态性法检测患者氯吡格雷代谢相关基因CYP2C19基因型。根据1个月后改良Rankin量表(mRS)评分,分为预后良好组(n=46,0分≤mRS≤1分)和预后不良组(n=24,2分≤mRS≤5分),对比两组患者CYP2C19基因型分布情况。
结果与结论:70例缺血性脑卒中患者中,CYP2C19*2、CYP2C19*3的基因型分布均为突变型(AG+GG)占比高,分别占比90.00%,98.57%,等位基因频率均为G等位基因占比高,分别占比73.57%,92.86%。预后良好组与预后不良组CYP2C19*2基因型分布比较差异有显著性意义(P < 0.05),CYP2C19*3基因型分布比较差异无显著性意义(P > 0.05)。结果表明,缺血性脑卒中患者氯吡格雷代谢相关基因CYP2C19*2、CYP2C19*3基因分布以突变型(AG+GG)为主,CYP2C19*2突变与患者的预后结局密切相关。

Abstract: BACKGROUND: Clopidogrel can be used for the treatment and prevention of ischemic stroke relapse. However, individual differences in clopidogrel metabolism exist among patients, with CYP2C19 gene polymorphism considered an important influencing factor.
OBJECTIVE: To investigate the distribution of clopidogrel metabolism-related gene polymorphisms in patients with ischemic stroke and to analyze their relationship with prognosis.
METHODS: A total of 70 patients with ischemic stroke admitted to Tianmen First People’s Hospital from January 2023 to January 2024 were selected, including 39 males and 31 females, with a mean age of (60.89±4.72) years. After 7–14 days of oral administration of clopidogrel bisulfate, fasting venous blood samples were collected from all patients. The CYP2C19 genotype, a clopidogrel metabolism-related gene, was detected using polymerase chain reaction-restriction fragment length polymorphism. Based on the modified Rankin Scale (mRS) score at 1 month, patients were divided into a good prognosis group (n=46, 0 ≤ mRS ≤ 1) and a poor prognosis group (n=24, 2 ≤ mRS ≤ 5). The distribution of CYP2C19 genotypes was compared between the two groups.
RESULTS AND CONCLUSION: Among the 70 patients with ischemic stroke, the genotype distributions of CYP2C19*2 and CYP2C19*3 were predominantly mutant types (AG+GG), accounting for 90.00% and 98.57%, respectively. The allele frequencies were dominated by the G allele, accounting for 73.57% and 92.86%, respectively. There was a significant difference in the distribution of CYP2C19*2 genotypes between the good prognosis group and the poor prognosis group (P < 0.05), whereas no significant difference was observed in the distribution of CYP2C19*3 genotypes (P > 0.05). These findings indicate that the distribution of clopidogrel metabolism-related genes CYP2C19*2 and CYP2C19*3 in patients with ischemic stroke is predominantly mutant types (AG+GG), and CYP2C192 mutation is closely associated with patient prognosis.
