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
目的:探讨血清视黄醇结合蛋白4(retinol binding protein 4,RBP4)水平与2型糖尿病(T2DM)大血管病变的关系。方法:选取T2DM患者189例,按照有无大血管病变分为大血管病变组85例、单纯糖尿病组104例。100例非糖尿病者为正常对照组。分别检...目的:探讨血清视黄醇结合蛋白4(retinol binding protein 4,RBP4)水平与2型糖尿病(T2DM)大血管病变的关系。方法:选取T2DM患者189例,按照有无大血管病变分为大血管病变组85例、单纯糖尿病组104例。100例非糖尿病者为正常对照组。分别检测血清RBP4浓度、体质指数(BMI)、血压、血脂和糖化血红蛋白(HbA1c)等。根据RBP4浓度由低到高按三分位法将189例T2DM患者分为3组,比较其动脉粥样硬化的发生情况;用Spearman相关分析分别分析糖尿病动脉粥样硬化与其他指标的相关性;用Pearson相关分析RBP4与其他指标的相关性,用多元逐步Logistic回归分析影响T2DM患者动脉粥样硬化最显著的因素。结果:T2DM患者(AS组和非AS组)的血浆RBP4水平高于正常对照组(P<0.05);RBP4上三分位组收缩压(SBP)、空腹胰岛素(FINS)、胰岛素抵抗指数(HOMA-IR)均高于其余2组,差异有统计学意义(P均<0.05);RBP4下、中、上三分位组患者大动脉粥样硬化的患病率也逐渐升高,分别为14.5%、21.4%和48.2%,RBP4上三分位组患者大动脉粥样硬化的患病率显著高于其余2组患者,差异有统计学意义(P均<0.05);Spearman相关分析显示,T2DM患者的大血管动脉硬化与年龄、病程、RBP4、HbA1c、总胆固醇(TC)及低密度脂蛋白胆固醇(LDL-C)呈正相关;Pearson相关分析显示T2DM患者RBP4浓度与BMI、SBP、血糖、FINS、HOMA-IR呈正相关。多元逐步Logistic回归分析显示T2DM患者动脉粥样硬化的发生与血浆RBP4、年龄、病程、LDL-C相关。结论:2型糖尿病患者动脉粥样硬化与血浆RBP4呈正相关关系,高血浆RBP4可能是T2DM动脉粥样硬化发生的独立危险因子之一。展开更多
