摘要
目的 探讨血管紧张素原 (angiotensinogen ,AGT)基因M2 35T分子变异与脑梗死 (cerebralinfarction ,CI)之间的关系。方法 采用聚合酶链反应 (PCR)及限制性片段长度多态性分析 (RFLP)法对 75例CI、48例健康对照进行了AGT基因M2 35T多态性检测。结果 CI组AGT基因T2 35等位基因频率为 0 .78,2 35TT基因型频率为 0 .6 4,与对照组(分别为 0 .6 0 4和 0 .375 )比较差异具有显著性 (χ2 =8.82 ,P=0 .0 0 3;χ2 =8.2 7,P =0 .0 0 4)。校正了CI的几种危险因素 (血总胆固醇、血糖及年龄 )后 ,2 35TT基因型仍可使CI发生的危险性增加 (分别为OR =3.2 89,P =0 .0 36 ;OR =2 .49,P =0 .0 2 3)。结论 AGT基因 2 35TT型可能是脑梗死发病的独立危险因素。
