Abstract: Objective To investigate the levels of serum retinol-binding protein 4 (RBP4 )and related factors in type 2 diabetic patients. Methods Eighty type 2 diabetic and patients 30 non-diabetic subjects were recruited into obese-diabetic group [body mass index (BMI) 1525 kg/m~2],normal-weighted diabetic group(BMI < 25 kg/m~2)and control group(BMI < 25 kg/m~2). Serum adiponectin(APN), RBP4 and hemoglobin A_1c (HbA_1c)triacylglycerol (TG),total cholesterol (TC).high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C)and were measured on fasting samples. BMI, waist/hips girth ratio (WHR) and insulin resistance index (HOMA-IR) were calculated. The correlation between RBP4 and other factors was analyzed. Results The concentration of RBP4 was significantly increased in obese-diabetic group and normal-weighted diabetic group compared with that in control group [ (30.02 ± 5.32), (20.10 ± 5.45), (12.02 ± 3.45) mg/L] (P < 0.01). The concentration of RBP4 was higher in obese-diabetic group than that in normalweighted diabetic group (P < 0.01). Univariate analysis showed serum RBP4 was positively associated with TG,BMI,FBG, WHR,FINS,HOMA-IR and negatively associated with APN (r = 0.225, 0.697, 0.323,0.557, 0.272, 0.461, -0.398). Conclusions The concentration of RBP4 is significantly higher in type 2 diabetic patients compared with that in normal subjects. RBP4 possibly plays an important role in the insulin resistance and the occurrence and development of type 2 diabetes.
