血清胱抑素C和视黄醇结合蛋白联合检测在糖尿病肾病临床诊断中的价值

目的 探讨血清胱抑素C(Cys C)和视黄醇结合蛋白(RBP)联合检测在糖尿病肾病早期临床诊断中的价值.方法 采用透射比浊法测定本院94例糖尿病住院患者与110例健康对照组的血清Cysc和RBP浓度,同时测定血肌酐(Scr)、尿肌酐(Ucr),并计算内生肌酐清除率(Ccr),比较各组Cys C、RBP与Ccr、Scr的相关性.结果 DN组与健康对照组比较,血清CysC、RBP差异均有统计学意义(P<0.01),且Cys C、RBP与Ccr呈负相关.结论 血Cys C、RBP联合检测在DN诊断中大大提高了准确性,对糖尿病肾病早期的临床诊断具有较大的实用价值.

Clinical Value of Combined Determination of Serum cystatin C and Retinol-binding protein in diabetic nephropathy

Objective To investigate the Clinical Value of Combined Determination of Serum cystatin C and Retinol-binding protein in diabetic nephropathy.Methods Immunoturbidimetry was employed to analyze Cystatin C(Cys C)and Retinol-binding protein;(RBP) from 94 cases of diabetic patients and 110 healthy control group .and we also detected thevalue of serum creatinine (Scr),urinary creatinine (Ucr),and calculated creatinine clearance rate (Ccr),compared the correlation of Cys C,RBP with Ccr,Scr.Results The contents of serum Cys C,RBP in the group of diabetic nephropathy were significant higher than that in healthy controllers(P<0.01),and Cys C,RBP were significantly negative correlation with Ccr.Conclusion The sensitivity and accuracy of the combined determination of serum Cys C,RBP in diabetic nephropathy are improved and might provide valuable proof for early diagnostic in diabetic nephropathy.
