Abstract

Background: To uncover the diagnostic potential of peripheral blood microRNA-200b (miRNA-200b) in renal interstitial injury in diabetic nephropathy (DN) patients.

Methods: A total of 50 diabetes subjects, 50 mild DN subjects, 50 moderate-severe DN subjects and 50 healthy subjects were included. Peripheral blood level of miRNA-200b in every subject was detected by reverse transcriptase-polymerase chain reaction (RT-PCR). Serum levels of renal function indicators were determined by enzyme-linked immunosorbent assay (ELISA). Meanwhile, relative levels of fibrosis damage indicators were examined by chemiluminescent immunoassay. Diagnostic potentials of miRNA200b in diabetes, mild DN and moderate-severe DN were assessed by depicting receiver operating characteristic (ROC) curves.

Results: Peripheral blood level of miRNA-200b was higher in DN subjects than diabetes subjects without vascular complications, especially moderate-severe DN patients. Peripheral blood level of miRNA-200b in DN subjects was negatively correlated to relative levels of serum creatinine, urinary nitrogen, cystatin, TGF-b, CIV and PCIII. ROC curves demonstrated diagnostic potentials of miRNA-200b in mild and moderate-severe DN.

Conclusions: Peripheral blood level of miRNA-200b is closely linked to the degree of renal interstitial injury in DN patients. MiRNA-200b may be a vital indicator in predicting the development of DN.

外周血MiRNA-200b水平可预测糖尿病肾病患者肾间质损伤。

背景:揭示外周血microRNA-200b (miRNA-200b)在糖尿病肾病(DN)患者肾间质损伤中的诊断潜力。方法:糖尿病患者50例，轻度DN患者50例，中重度DN患者50例，健康者50例。采用逆转录聚合酶链反应(RT-PCR)检测各组患者外周血miRNA-200b水平。采用酶联免疫吸附试验(ELISA)测定血清肾功能指标水平。同时，采用化学发光免疫分析法检测纤维化损伤指标的相对水平。通过绘制受试者工作特征(ROC)曲线评估miRNA200b在糖尿病、轻度DN和中重度DN中的诊断潜力。结果:DN患者外周血miRNA-200b水平高于无血管并发症的糖尿病患者，尤其是中重度DN患者。DN患者外周血miRNA-200b水平与血清肌酐、尿氮、胱抑素、TGF-b、CIV、PCIII相对水平呈负相关。ROC曲线显示miRNA-200b在轻度和中重度DN中的诊断潜力。结论:外周血miRNA-200b水平与DN患者肾间质损伤程度密切相关。MiRNA-200b可能是预测DN发展的重要指标。
