Abstract: 目的:观察非诺贝特对糖尿病(DM)大鼠血脂联素和脂联素基因的表达及内皮细胞功能的干预作用.方法:采用小剂量链脲佐菌素(STZ,25 mg/kg)和高脂饮食诱导的方法建立DM大鼠模型.DM大鼠20只随机分为两组:DM (DM)组10只和DM非诺贝特(DF)组10只,正常Wistar大鼠10只为正常对照(NC)组.DM组及DF组大鼠给予高脂喂养,NC组大鼠给予正常饮食,3组大鼠每日摄取的热量相等,同时DF组大鼠给予非诺贝特灌服.8周后,腹主动脉取血测定空腹血糖(FBG)、游离脂肪酸(FFA)、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白-胆固醇(HDL-C)、肿瘤坏死因子-α(TNF-α)、脂联素和可溶性血管细胞黏附分子-1(sVCAM-1),并计算低密度脂蛋白-胆固醇(LDL-C);取肾周脂肪组织RT-PCR技术半定量分析脂联素基因表达.结果:与NC组相比,DM组FPG、FFA、TC、TG、LDL-C、TNF-α和sVCAM-明显增多(P＜0.05～P＜0.01),血HDL-C、脂联素和脂肪组织内的脂联素基因表达下降(P＜0.01).与DM组相比,DF组的血FFA、TG 、FBG、LDL-C、TNF-α和sVCAM-1水平下降(P＜0.05),同时血HDL-C、脂联素和脂肪组织内的脂联素基因表达显著升高(P＜0.01).结论:非诺贝特治疗可能通过改善脂联素基因的表达和血脂联素水平起到保护内皮细胞的作用.
