哈萨克族原发性高血压患者血浆视黄醇结合蛋白4水平及其相关性研究

目的 分析新疆哈萨克族(哈族)原发性高血压(EH)患者血浆视黄醇结合蛋白4(RBP4)水平及其与血压、血脂、血糖、胰岛素及胰岛素抵抗指数(HOMA-IR)的关系.方法 以2008年8月至11月流行病学调查的新疆哈族人81例为研究对象.哈族EH患者41例为病例组,哈族健康人群40例为对照组.测量血压,测定血浆RBP4、胰岛素、血糖、TC、TG、HDL-C、LDL-C、载脂蛋白A1和载脂蛋白B,计算HOMA-IR.结果 ①EH组血浆RBP4水平明显高于对照组[(32.74±9.93)mg/L与(21.92±10.43)mg/L,P<0.01];②EH组血浆RBP4与年龄、收缩压、舒张压、血糖、HOMA-IR呈显著正相关(r<,s>=0.618、0.775、0.565、0.317、0.369,P<0.01或P<0.05);在对照组中,RBP4与血糖呈正相关(r<,s>=0.414,P<0.01).③多元回归分析显示:EH组收缩压(标准化偏回归系数0.591,t=5.695,P=0.000)进入回归方程,是影响血浆RBP4水平的独立因素.结论哈族EH患者血浆RBP4水平升高,并与收缩压、舒张压、血糖、HOMA-IR呈显著正相关,RBP4可能通过促进胰岛素抵抗而参与了EH的发生、发展.

Plasma level of retinol binding protein 4 and its correlation in patients with essential hypertension of Kazakans

Objective To explore the plasma level of retinol binding protein 4 (RBP4) in patients with es-sential hypertension (EH) of Xinjiang Kazakans and the relations between plasma RBP4 level and blood pressure, blood lipids,blood glucose, insulin, and HOMA-IR. Methods 81 Kazakans cases who were investigated between August and November of 2008 were selected as subjects. They were divided into EH group(n=41)and control group (n=40). Blood pressure was measured. Fasting venous blood was drawn to detect the plasma RBP4, fasting insulin (FINS), fasting plasma glucose(FPG), total cholesterol(TC), triglyceride(TG), high density lipoprotein cholesterol (HDL-C)、low density lipoprotein cholesterol (LDL-C), apoprotein-A1 (APO-A1) and apoprotein-B (APO-B), and concentration in EH group was significantly higher than that in control group[ (32.74±9.93) mg/L vs (21.92± pressure (DBP),FPG,and HOMA-IR in EH group(r,=0.618,0.775,0.565,0.317,0.369,P<0.01 or P< showed that SBP was independent factor to affect the RBP4 level in EH group(Standardized Coefficients is 0.591, t=5. 695, P=0.000). Conclusion The plasma RBP4 concentration is increased in patients with EH of Kazakans, and is positively correlated with SBP,DBP,FPG,HOMA-IR in EH group. RBP4 may involve in the development of EH by promoting insulin resistance.
