摘要:

目的 探讨Ⅰ型糖尿病肾病(diabetic nephropathy,DN)的早期诊断指标。方法 检测47例Ⅰ型糖尿病病人和30例健康者(对照组)的尿液β2微球蛋白(Beta-2-microglobulin,β2-MG)、N-乙烯-β-D-氨基葡萄糖苷酶(N-acetyl beta-D-glucosaminidase,NAG)及视黄醇结合蛋白(Retinol binding protein,RBP)等指标,根据尿白蛋白排泄率(urinary albumin excretion,UAE)分为将患者DM组(UAE<20 μg/min)和DN组(UAE 20~200 μg/min),用统计学方法分析上述指标在各组之间的差异。结果 RBP与UAE正相关(r=0.24,P=0.032),RBP在3组之间差异有统计学意义(P=0.047),DN组高于DM组和对照组,NAG及β2-MG于各组之间差异无统计学意义。结论 尿RBP可以作为诊断早期1型DN的参考指标之一,但其并不比UAE更敏感。

Abstract:

Objective To clarify whether the urinary excretion of n-acetyl-β-d-glucosaminidasen(NAG), Retinolbinding protein(RBP) andβ2-microglobulin(β2-MG) can be used as indicators for the early diagnosis of type Ⅰ diabetic nephropathy. Methods A total of 47 selected patients with type Ⅰ diabetes admitted to Beijing Children's Hospital and 30 healthy controls were recruited in this study. Urine levels of albumin were measured by the radioimmunoassay; NAG, RBP, β2-MG, and IgG were determined by enzyme-linked immunosorbent assay(ELISA). Results The 47 patients were divided into two groups based on the rate of urinary excretion of albumin, group 1 patients had normal albuminuria(UAE<20 μg/min); group two had microalbuminuria(UAE 20~200 μg/min); group three was normal control. The urinary level of RBP was significantly higher in patients with microalbuminuria than in the patients with normal albuminuria(P=0.046) and normal control(P=0.039). The urinary level of albumin was positively correlated with the RBP(r=0.24, P=0.032). Conclusion The urinary RBP can be a marker in diagnosis of early DN, but it is not more sensitive than UAE.
