高血压患者血清抵抗素水平与颈动脉内膜-中层厚度的相关性研究

目的:抵抗素是一种脂肪细胞因子,并且它是一种富含半胱氨酸的分泌蛋白.本研究主要探讨高血压患者血清抵抗素水平与颈动脉内膜-中层厚度(IMT)的相关性.方法:入选272例原发性高血压患者,根据他们的血清抵抗素水平由低到高平均分为3组,第一组(血清抵抗素水平1.233~3.701 ng/ml)91人,第二组(血清抵抗素水平3.728~8.777 ng/ml)91人,第三组(血清抵抗素水平8.809~28.658 ng/ml)90人.结果:第三组的颈动脉IMT和颈动脉最大IMT均大于第一组和第二组(P均<0.05).多元线性回归分析示,在控制了年龄、血糖、尿酸、低密度脂蛋白胆固醇、收缩压、舒张压等因素之后,血清抵抗素水平与颈动脉IMT(β=0.220,t=5.793,P=0.000)呈独立的显著正相关.在控制了年龄、血糖、体重指数、舒张压、糖尿病、血清高敏C反应蛋白、总胆固醇、甘油三酯之后,血清抵抗素水平与颈动脉最大IMT(β=0.189,t=4.733,P=0.000)也呈独立的显著正相关.结论:在原发性高血压的患者,血清抵抗素水平与增厚的颈动脉IMT独立相关.

Relationship Between Serum Resistin and Carotid Intima Media Thickness in Patients With Essential Hypertension

Objective:To determine the relationship between serum resistin levels and carotid intima media(IMT)thickness in patients with essential hypertension. Methods:This study consisted of 272 patients with essential hypertension. The patients were divided into three groups according to their serum resistin levels. Group 1,n=91,serum resistin level 1.233-3.701 ng/ml;Group 2,n=91,serum resistin level 3.728-8.777 ng/ml;and Group 3,n=90,serum resistin level 8.809-28.658 ng/ml. Results:The carotid IMT and maximum carotid IMT of Group 3 were the highest in three groups.(P＜0.05).As shown in multivariate analysis for factors affecting carotid IMT,serum resistin level(β=0.220,t=5.793,P=0.000)was independently associated with the carotid IMT after controlling the age,blood glucose,uric acid,low-density lipoprotein cholesterol,systolic blood pressure and diastolic blood pressure. Serum resistin level(β=0.189,t=4.733,P=0.000)was independently associated with the maximum carotid IMT after controlling the age,blood glucose,body mass index,diastolic blood pressure,diabetes mellitus,high sensitivity C reactive protein,total cholesterol and triglyceride. Conclusion:Serum resistin was independently associated with the increased carotid IMT in essential hypertension patients.
