Abstract： 目的 探讨E-选择素基因SER128ARG(S128R)多态性在急性心肌梗死(AMI)患者和正常人群中的分布特点及与AMI的易感相关性,以及对血清E-选择素水平的影响.方法 采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术,检测168例AMI患者和200例健康对照者E-选择素基因多态性,同时采用酶联免疫吸附试验(ELISA)法检测所有参与者血清E-选择素水平.结果 E-选择素基因S128R基因型频率和等位基因频率,在AMI组和对照组的分布差异有统计学意义(P＜0.05);基因型频率的相对风险分析发现,SR杂合子基因型携带者患AMI的风险是SS纯合子基因型的2.234倍(OR=2.234,95%CI:1.112～4.437);AMI组血清E-选择素水平明显高于对照组(P＜0.05);SR杂合子基因型携带者血清E-选择素水平显著高于SS纯合子基因型(41.65±8.87)μg/L和(34.23±6.72)μg/L,P＜0.05.结论 E-选择素S128R基因多态性与AMI的发病有关联,并影响血清E-选择素水平;提示R基因可能是AMI发病的遗传易感基因.
