摘要
目的:评价联合尿N-乙酰-β-D-氨基葡萄糖苷酶(NAG)与尿/血渗透压比测定在糖尿病肾病早期诊断中的价值。方法:2型糖尿病患者150例,按尿白蛋白排泄率(UAER)分为A组65例(UAER<20μg/min),B组54例(20μg/min≤UAER<200μg/min),C组31例(UAER≥200μg/min),正常对照组30例,测定血、尿渗透压、尿/血渗比及尿NAG,并比较。结果:(1)相关分析显示,尿NAG与病程、UAER、BUN、年龄呈显著正相关(r=0.296、0.424、0.247、0.266,P<0.01),与Hb A1c、尿糖、血肌酐亦呈正相关(r=0.217、0.205、0.245,P<0.05);尿/血渗比与病程、UAER、血肌酐、年龄呈显著负相关(r=-0.259、-0.371、-0.252、-0.282,P<0.01),与Hb A1c呈负相关(r=-0.227,P<0.05),与GFR呈正相关(r=0.200,P<0.05)。(2)A、B、C各组与对照组尿NAG及尿/血渗比差异均存在统计学意义(P<0.05)。结论:联合尿NAG与尿/血渗比测定可全面评估肾小管功能,有助于糖尿病肾病的早期诊断。
Objective： To evaluate the value of combined with urine to blood osmolality ratio and urinary N-acetyl- β -D-glocosaminidase （ NAG ） in early diagnose of diabetic nephropathy. Method： A total of 150 patients with type 2 diabetes mellitus were divided into three groups including group A （ UAER〈20 μ g/min, 65 cases ）, group B （ 20 μ g/min ≤ UAER〈200 μg/min, 54 cases ）, and group C （ UAER ≥ 200 μg/min, 31 cases ） . 30 healthy subjects were enrolled as the control group. The blood-urinary osmolality and urinary NAG were determined, which were compared between the three groups. Result： （ 1 ） Correlation analysis showed that urinary NAG was positively correlated with course, UAER, BUN, age （r=0.296, 0.424, 0.247, 0.266, P〈0.01 ）, HbAlc, urine-glucose, and creatinine （r=0.217, 0.205, 0.245, P〈0.05 ） . Urine to blood osmolality ratio was negatively correlated with disease course, UAER, serum creatinine, age （r=-0.259, -0.371, -0.252, -0.282, P〈0.01 ）, HbAlc （ r=-0.227, P〈0.05 ）, but positively GFR （ r=0.200, P〈0.05 ） . （ 2 ） There were significant differences between the three groups in urinary NAG and urine to blood osmolality ratio （ P〈0.05 ） . Conclusion： Urinary NAG combined with urine to blood osmolality ratio contribute to complete assessment the renal tubular function, and is conducive to the early diagnosis of diabetic nephropathy.
