ABSTRACT
Objective To explore the changes of detection of urine a1-MG and KNG1 in simple type 2 diabetes mellitus and diabetic nephropathy patients.Methods 66 cases of diabetic patients in General Hospital of Ningxia Medical University from September 2016 to March 2017 were recruited,and the patients were divided into two groups,as follows:the diabetic nephropathy (DN) group 34 cases as experimental group,and the simple type 2 diabetes mellitus (DM) group 32 cases as control group.Than DN group was divided into two groups according to HbAlc,A groups 19 cases HbAlc was less than 10％,B groups 15 cases HbAlc was greater than or equal to 10％.The urine α1-MG,urine KNG1 and other biochemical indicators were mearured for all subjects.Results Compared with the DM group,the urine α1-MG in DN group was significantly lower (t=9.972,P＜0.01),but the result of the urine KNG1 was the opposite (t=-3.356,P＜0.01).The urine α1-MG and serum GLU in B group were significantly higher than those of the A group (t=-2.092,-3.464,all P＜0.05),but the result of the serum Cr was the opposite (t=2.181,P＜0.05).The level of urine α1-MG in DN group were positively correlated with HbAlc and urine KNG1 (r=0.33,0.355,all P＜0.05).Conclusion There were some changes in the expression of urine α1-MG and KNG1 in the occurrence and development of diabetic nephropathy,which provide the basis for the clinical diagnosis of diabetic nephropathy.
