摘要
背景与目的:糖尿病肾病(DN)是终末期肾病(ESRD)的主要决定因素。改变的microRNA水平会导致严重的慢性疾病,例如糖尿病。我们旨在测量DN中两种microRNA(microRNA126和192)的表达水平,并研究它们与蛋白尿水平的关系。 方法:该研究包括229名受试者(134名DN患者和95名对照)。测定血清脂质谱,葡萄糖水平,糖化血红蛋白(HbA1c)水平和肾功能。通过实时PCR确定microRNA126和microRNA192的表达水平。 结果:DN患者的体重,BMI值,葡萄糖水平(P <0.001),HbA1c水平(P <0.001),尿白蛋白-肌酐比值(ACR)值(P <0.001),尿素水平(P = 0.002)较高。 ,并且肌酐水平(P = 0.004)和microRNA192(P <0.001)和microRNA126(P <0.001)的表达水平均低于对照组。 MicroRNA126的表达与年龄,估计的肾小球滤过率(eGFR)和microRNA192的表达呈正相关,与血糖,HbA1c,尿素,肌酐和ACR呈负相关。 MicroRNA192的灵敏度(91%),特异性(94%)和曲线下面积(AUC)(0.967)值均高于microRNA126(灵敏度为90%;特异性为68%; AUC为0.897),因此可以准确诊断DN 。 结论:MicroRNA126和microRNA192的表达均与DN明显相关,并可能由于与大量白蛋白尿的密切关系而决定了疾病的进展。
