4、人群230例作为健康组。采用实时荧光定量聚合酶链式反应PCR(RT-qPCR)法检测两组病人血清miR-1283表达情况并对比。另根据中医辨证分型标准将疾病组分为不同证型,比较疾病组不同中医证型病人血清miR-1283表达水平。结果 疾病组miR-1283表达水平(0.420.07)低于健康组(0.980.18)(t=44.47,P0.05);阴竭阳脱型病人血清miR-1283表达水平均高于痰瘀互结型、寒凝心脉型、气虚血瘀型、气虚痰瘀互阻型、气虚痰浊闭阻型、气阴两虚型病人(P0.05);痰瘀互结型病人血清miR-1283表达水平低于寒凝心脉型、气虚血瘀型、气虚痰瘀互阻型、气虚痰浊闭阻型、气阴两
5、虚型(P0.05)。结论 急性心肌梗死病人血清miR-1283表达水平偏低,且不同证型病人血清miR-1283表达水平有差异,提示该指标可以作为急性心肌梗死病人中医证型的分型依据。关键词:心肌梗死;微RNA-1283;实证;虚实夹杂;诊断;中医证型Analysis of the relationship between serum microRNA-1283 expression and TCM syndrome types in patients with acute myocardial infarctionLIN Danfeng,CHEN Yanqiao,NIU WeizhouAutho
