摘要:

目的 探讨2型糖尿病肾病(DN)患者血清miR-27b-3p、miR-342-3p表达特点及其对DN的诊断价值。方法 将157例2型糖尿病患者根据尿白蛋白与肌酐比率(UACR)分为正常白蛋白尿(NA)组49例、微量白蛋白尿(MA)组41例、大量白蛋白尿(DN)组67例。收集临床资料,采用实时定量聚合酶链反应检测血清miR-27b-3p、miR-342-3p表达,全自动生化分析仪检测血尿素氮(BUN)、血肌酐(Scr),双抗体夹心酶联免疫吸附试验检测尿液Ⅳ型胶原(Ⅳ-C)、层粘连蛋白(LN)、Ⅲ型前胶原肽(PCⅢ)。分析DN发病的影响因素以及miR-27b-3p、miR-342-3p对DN的诊断价值。结果 与NA组比较,DN组和MA组HbA1c、UACR、尿Ⅳ-C、尿LN、尿PCⅢ水平均增加,而miR-27b-3p、miR-342-3p表达均降低(P<0.05),DN组BUN、Scr水平增加、估算肾小球滤过率(eGFR)水平降低(P<0.05)。较高水平的尿PCⅢ是DN的危险因素,而较高水平的miR-27b-3p、miR-342-3p、eGFR是DN保护因素(P<0.05)。miR-27b-3p、miR-342-3p表达与eGFR呈正相关(r分别为0.647、0.661,P<0.05),与尿PCⅢ呈负相关(r分别为-0.739、-0.766,P<0.05)。联合eGFR、尿PCⅢ、miR-27b-3p、miR-342-3p诊断DN的AUC高于单独eGFR、尿PCⅢ、miR-27b-3p、miR-342-3p(Z分别为5.631、5.794、6.715、4.577,P<0.05)。结论 血清miR-27b-3p、miR-342-3p表达降低与DN患者肾功能下降和肾脏疾病发生均有关,可作为DN辅助诊断的生物学指标。

Abstract:

Objective To investigate the serum expression characteristics of miR-27b-3p and miR-342-3p in type 2 diabetic nephropathy (DN) patients and the diagnostic value for DN. Methods A total of 157 patients with DN were selected and divided into the normal albuminuria group (NA group, n=49), the microalbuminuria group (MA group, n=41) and the macroalbuminuria group (DN group, n=67) according to the ratio of albumin to creatinine (UACR) of urine specimens. Clinical data and the expression of serum miR-27b-3p and miR-342-3p, renal function and urinary fibrosis indicators were detected by real-time quantitative polymerase chain reaction. Blood urea nitrogen (BUN) and blood creatinine (Scr), were detected by automatic biochemical analyzer. Urine type Ⅳ collagen (Ⅳ-C), laminin (LN) and type Ⅲprocollagen peptide (PCⅢ) were detected by double-antibody sandwich enzyme-linked immunosorbent assay. The factors influencing the pathogenesis of DN and the diagnostic value of miR-27b-3p and miR-342-3p for DN were analyzed. Results Compared with the NA group, the levels of HbA1c, UACR, urinary Ⅳ-C, urinary LN and urinary PCⅢ were increased, while the expresson levels of miR-27b-3p and miR-342-3p were decreased in the DN group and the MA group (P<0.05). Levels of BUN and Scr were increased in the DN group (P<0.05), and eGFR level decreased (P<0.05). The higher level of urinary PCⅢ was a risk factor for DN, while the higher levels of miR-27b-3p, miR-342-3p and eGFR were protective factors of DN (P<0.05). The expressions levels of miR-27b-3p and miR-342-3p were positively correlated with eGFR (r = 0.647, 0.661, P<0.05) and negatively correlated with urinary PCⅢ (r=-0.739, P<0.05). The area under the curve for diagnosing DN by combining eGFR, urinary PCⅢ, miR-27b-3p and miR-342-3p was higher than that of eGFR, urinary PCⅢ, miR-27b-3p, miR-342-3p alone (Z=5.631, 5.794, 6.715, 4.577, P<0.05). Conclusion The decreased expressions of serum miR-27b-3p and miR-342-3p are associated with decreased renal function and DN occurrence in patients with type 2 diabetes, which can be used as biological indicators for the auxiliary diagnosis of DN.
