摘要: 目的分析中国汉族人群凝血酶激活纤溶抑制物基因启动子区-438A/G (TAFI-438A/G)多态性与动脉粥样硬化性脑梗死(ACI)发病的关系。方法225 例ACI 患者(病例组)和184 例健康体检者(对照组)采用聚合酶链反应-限制性内切酶片段长度多态性分析方法(PCR-RFLP)检测TAFI-438A/G 多态性。结果TAFI-438A/G 基因型及等位基因频率在病例组与对照组之间无显著性差异。性别分层后,男性脑梗死组A等位基因频率为28.6%,高于对照组20.6% (P=0.039);AA基因型为9.0%,高于对照组1.9% (P=0.019);在女性中无显著性差异。结论TAFI-438A/G可能与男性脑梗死的发病有关,AA基因型可能增加男性脑梗死患病风险。

Abstract: Objective To research the relationship between promoter polymorphism-438 A/G of thrombin-activatable fibrinolysis inhibitorgene (TAFI-438 A/G) and atherosclerotic cerebral infarction (ACI) in Chinese Han population. Methods TAFI-438A/G genotypes andtheir allele frequencies were identified with the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) in225 ACI patients and 184 healthy controls. Results There was no significant difference of TAFI-438A/G polymorphism between ACI groupand control group. Stratified by gender, in males, the incidence of A allele was 28.6% in ACI group, and 20.6% in control (P=0.039); of theAA genotype was 9.0% in ACI group, and 1.9% in control (P=0.019). But no significant difference was found in females. ConclusionTAFI-438A/G polymorphism is associated with the risk of ACI in males, that AA genotype may increase the risk of ACI.
