摘要 目的探讨CXCL12基因rs2839688位点多态性与冠心病的关系。方法选择冠心病患者545例,经冠状动脉造影证实一支或多支血管狭窄50%以上者279例(观察组),冠状动脉造影正常且无其他粥样硬化证据者266例(对照组)。两组各随机抽取20例,采用ELISA法检测血浆CXLC12;采集所有研究对象静脉血,采用直接测序法检测CXCL12基因rs2839688位点基因型及等位基因分布频率,并分析其多态性与血浆CXLC12水平的关系。结果观察组血浆CXCL12水平低于对照组(P<0.01)。两组CXCL12基因rs2839688位点共检测出GG、GC、CC三种基因型,观察组三种基因型频率分别为66.8%、28.7%、2.5%,对照组分别为69.5%、28.9%、1.5%,两组比较P均>0.05;观察组、对照组C等位基因分布频率分别为16.8%、16.0%,G等位基因分别为83.2%、84.0%,两组比较P均>0.05。两组基因型及等位基因频率符合Hardy-Weinberg平衡定律。两组各基因型者血浆CXCL12水平比较P均>0.05。结论 CXCL12可能与冠心病的发生有关,但其rs2839688位点多态性与冠心病的发病可能无关。
