摘要 目的:建立高血压伴胰岛素抵抗(IR)动物模型并观察血清脂联素(adiponectin,APN)、肿瘤坏死因子α(tumor necrosis factorα,TNFα)的变化。方法:6周龄的雄性Wistar大鼠分为2组,对照组(n=10)以普通标准饲料+普通自来水喂养;果糖组(n=10)普通标准饲料+10%果糖水喂养。尾部测量法测定大鼠血压;IR指标采用胰岛素敏感性指数(insalin sensivity index,ISI)=-ln[空腹血糖(FBG)×空腹胰岛素(FIns)];放免法测定血清APN和TNFα的浓度。结果:第8周末果糖组血压、FIns和TNFα水平明显升高,ISI和APN明显下降,2组间差异均有显著性:FBG无差异;第14周末,2组间ISI、APN和TNFα的差异有显著性,果糖组FBG较对照组有显著升高;相关性分析表明,APN与FIns、ISI和TNFα水平的相关性显著。结论:10%果糖水喂养的Wistar大鼠,具有典型的高血压伴IR的特点;ISI降低的同时伴有血清APN下降和TNFα的升高。
