Abstract：Objective To investigate the change of serum C-peptide level in type 2 diabetic nephrosis patients. Methods We recruited 120 patients with type 2 diabetes. The level of fasting plasma glucose (FBG), glycated hemoglobin (HbA1c), fasting C-peptide (FCP) and urinary albumin excretion rate (UAER) were measured.According to UAER, 120 patients were divided into Group Ⅰ: normal albuminuria group, 34 patients; Group Ⅱ:microalbuminuria group, 40 patients; Group Ⅲ: clinical albuminuria, 46 patients. At same time, we selected 30 healthy people as control group. Results The level of C-peptide decreased significantly in Group Ⅱ and Group Ⅲ compared with that of control group (P ＜0.01 ). The difference of C-peptide level between Group Ⅱ, Group Ⅳ and Group Ⅰ was statistically significant (P ＜ 0.01 ). The level of C-Peptide and urinary albumin excretion rate was negatively correlated (R = -0. 745 ,P ＜ 0. 01 ). Conclusion The decline of serum C-pcptide may be involved in the development of type 2 diabetic nephropathy.
