Significance of Combined Detection of Serum Retinol-Binding Protein and AnnexinA2 in Diabetic Nephropathy / 现代检验医学杂志

ABSTRACT

Objective To explore the significance of detection serum Retinol-Binding Protein and AnnexinA2 in diabetic ne-phropathy.Methods According to 24-UAER level,80 diabetic patients with suspected DN were devided into three groups, that was A (25 cases),B (26 cases)and C (29 cases)group,and control group (NC)was 25 cases.HbA1c,BUN,Scr,UA and RBP leves were detected by the standard method.The expression level of Annexin A2 were detected by real-time PCR. Results There were obvious differences of HbA1c,BUN,Scr,UA and RBP levels among three groups and NC group (t=4.64~13.65,P0.05),there were differences of RBP (t=15.26,P<0.05).To HbA1c,BUN,Scr UA and RBP,there were differences be-tween A groups and C groups (t=5.26~25.33,P<0.05),there were the same results between B groups and C groups (t=4.02~18.33,P<0.05).To expression level of AnnexinA2 there were differences among three group and NC group ((t=13.45~24.25,P<0.05)).There exist positive correlation between the expression of AnnexinA2 and RBP level (r=0.95, P<0.01).Conclusion Combined detection of serum RBP and expression level of AnnexinA2 may be a sensitive and early phase indicator for impairment of renal function for diagnosis of diabetic nephropathy.
