文摘目的探讨血浆肾素活性(PRA)、C1q/TNF相关蛋白3(CTRP3)与2型糖尿病(T2DM)患者颈动脉粥样硬化的关系。方法选择T2DM患者137例,根据颈动脉内膜—中层厚度分为斑块组83例、无斑块组54例。收集两组一般临床资料[性别、年龄、BMI、血压(收缩压、舒张压)、基础疾病(高血压、高脂血症)、吸烟史、饮酒史、心脑血管疾病家族史、饮食方式、运动方式]、实验室检查资料[TC、TG、LDL-C、HDL-C、空腹血糖(FPG)、空腹胰岛素(FINS)、胰岛素抵抗指数(HOMA-IR)、糖化血红蛋白(HbA1c)、PRA、CTRP3]。比较两组一般临床资料和实验室检查资料,将两组上述有统计学差异指标纳入多元逐步Logistic回归模型,分析影响T2DM并发颈动脉粥样硬化的危险因素。采用受试者工作特征(ROC)曲线评估血浆PRA、CTRP3水平预测T2DM并发颈动脉粥样硬化的效能。结果两组一般临床资料共纳入12个因素,单因素分析发现,两组BMI、收缩压、有吸烟史例数、合并高血压例数、合并高脂血症例数、不合理饮食例数、缺乏运动例数比较差异均有统计学意义(P均<0.05),而性别构成、年龄、舒张压、有饮酒史例数、有心脑血管疾病家族史例数比较差异均无统计学意义(P均>0.05);两组实验室检查资料共纳入10个因素,单因素分析发现,两组TC、FPG、FINS、HOMA-IR、HbA1c、PRA、CTRP3比较差异均有统计学意义(P均<0.05),两组TG、HDL-C、LDL-C比较差异均无统计学意义(P均>0.05)。多元逐步Logistic回归分析发现,收缩压、TC、HbA1c、PRA、CTRP3是T2DM并发颈动脉粥样硬化的危险因素(P均<0.05)。ROC曲线分析显示,血浆PRA水平预测T2DM并发颈动脉粥样硬化的曲线下面积(AUC)为0.731(95%CI:0.644~0.817),其截断(cut off)值为4.21μg/(L·h),此时其预测T2DM并发颈动脉粥样硬化的敏感度为72.29%、特异度为79.63%;血浆CTRP3水平预测T2DM并发颈动脉粥样硬化的AUC为0.801(95%CI:0.720~0.881),其cut o
