老年代谢综合征患者趾臂指数与Th17细胞及相关细胞因子的相关性

目的 探讨老年代谢综合征患者趾臂指数(TBI)与Th17细胞及其与细胞因子白细胞介素-17(IL-17)、白细胞介素-6(IL-6)及肿瘤坏死因子α(TNF-α)的相关性.方法 依据2004年中国糖尿病学会(CDS)提出的标准入选161例代谢综合征患者,应用全自动动脉硬化测定仪VP1000测定患者的TGBI,将患者分为TBI正常组和TBI降低组.采用流式细胞检测技术检测患者外周血中Th17细胞水平,并采用ELISA法检测所有高血压患者的血清IL-17、IL-6及TNF-α浓度水平.结果 TBI降低组外周血Th17细胞比例明显高于TBI正常组(t=7.116,P＜0.01).TBI降低组Th17细胞因子IL-17、IL-6及TNF-α血清浓度较TBI正常组显著升高(P＜0.01).相关及回归分析显示,TBI与外周血Th17细胞比例、血清IL-17、IL-6及TNF-α血清浓度水平呈负相关(r=-0.443、-0.485、-0.348及-0.429,均P＜0.001),Th17细胞比例、IL-17、IL-6、TNF-α血清浓度水平是影响baPWV的主要因素.结论 老年代谢综合征患者TBI与Th17细胞及其细胞因子相关.

Association between toe brachial index and Th17 cells and Th17-associated cytokines in old metabolic syndrome patients

Objective To investigate the correlations b etween toe brachial index (TBI) and Th17 cells and Th17-associated cytokines in old metabolic syndrome pa tients. Methods According to the standard of metabolic syndrome p resented by Chin ese Diabetes Society in 2004,161 metabolic syndrome patients were eligible recr uited.TBI was observed using VP-1000 automatic atherosclerosis analyzer,and th en the patients were divided into normal TBI group and lower TBI group,respecti vely.Frequencies of peripheral blood Th1...
