We aimed to investigate the correlation of RBP4 expression with atherosclerosis of the carotid artery in T2DM. A total of 1,076 subjects were investigated for intima-media thickness of the bilateral common carotid arteries, and they were divided into three groups： in group Ⅰ, patients had normal neck vascular ultra- sound, in group Ⅱ, intimal carotid artery media thickness was equal to or more than 1 mm, and in group Ⅲ, carotid artery plaque was present. Height, weight, blood pressure （BP）, fasting plasma glucose （FPG）, hemoglobin Alc （HbA1c）, total cholesterol （TC）, triglyceride （TG）, low-density lipoprotein cholesterol （LDL-C）, high-density lipopro- tein cholesterol （HDL-C）, apolipoprotein A-1 （apoA-1）, apolipoprotein B （apoB） and lipoprotein （a） [Lp（a）] were determined by routine laboratory methods. RBP4 and high sensitivity C reactive protein （HsCRP） were measured by an enzyme-linked immuno-sorbent assay, and insulin concentration was measured by an electrochemiluminescence sandwich immunoassay. Duration of diabetes, waist and BP, FPG, HbAlc, TG, TC, LDL-C, APOB, Lp（a）, HsCRP, RBP4 and homeostasis model assessment insulin resistance index （HOMA-IR） were significantly lower in group I than in the other two groups （P〈0.01, P〈0.01）. Plasma levels of HbAlc, RBP4, LDL-C, TC, HOMA-IR, HsCRP and Lp（a）, waist and BP were significantly increased in group III than in group II （P〈0.01）. Multivariate logistic regression analysis showed that there were seven factors associated with the occurrence of carotid artery atherosclero- sis and its risks in descending order were： high LDL-C, high waist, high HsCRP, duration of diabetes, high HOMA-IR, HbAlc and high RBP4. Our finding supported that RBP4 was positively correlated with carotid atherosclerosis in patients with T2DM and could be used as an early predictor of cardiovascular disease.展开更多
