摘要 目的探讨活化因子Ⅶ(FⅦa)及其基因MspI多态性与中国汉族人高血压合并脑梗死的关系。方法采用候选基因及病例对照的方法,以聚合酶链反应及限制性内切酶片段长度多态性(PCRRFLP)分析技术,进行FⅦ基因MspI多态性分析并确定基因型,同时采用重组可溶性组织因子法(rSTF2219)测定血浆FⅦa水平。结果①与高血压组比较,脑梗死组血浆FⅦa水平显著增高(278±059对253±062μg/L,P<005);高血压组与正常对照组比较差异无显著性(253±062对241±061μg/L,P>005);Logistic回归分析显示,血浆FⅦa水平增高是高血压合并脑梗死的重要危险因素(OR1134,P<005)。②FⅦ基因型频率分布符合HardyWeinberg平衡定律,基因型及等位基因频率分布在各组间均无显著性差异(P均>005)。③各组血浆FⅦa水平均与FⅦ基因多态性显著相关,M1M1纯合子血浆FⅦa水平显著高于M2等位基因携带者(P<005)。结论血浆FⅦa水平增高是高血压合并脑梗死的重要危险因素,FⅦa水平受其基因MspI多态性的影响。
