摘要 目的初步分析急性ST段抬高心肌梗死(STEMI)患者低密度脂蛋白受体(LDLR)基因启动子区9个基因位点的单核苷酸多态性(SNP)。方法选择经急诊确诊的急性STEMI患者24例(病例组)和健康体检者13例(对照组),抽取静脉血检测血脂和用于DNA提取,以高分辨溶解曲线方法分析技术检测SNP。比较两组三酰甘油(TG)、总胆固醇(TC)、高密度脂蛋白(HDL)和低密度脂蛋白(LDL)的水平,以及LDLR基因启动子区9个SNP位点基因型和等位基因频率。结果病例组血清LDL高于对照组(P<0.05),而HDL低于对照组(P<0.05),两组血清TG、TC比较差异无统计学意义(P>0.05)。LDLR启动子区9个SNP位点的基因型和等位基因频率差异无统计学意义(P>0.05),9个SNP位点的HRM曲线变异未出现群组效应,且出现变异的样品号高度一致。结论急性STEMI患者存在血脂的异常,但其LDLR基因启动子区基因位点未发生变异修饰。
