摘要 目的 研究西布曲明对女性超重患者的体重、血清TNF-α、sTNF-αRⅡ及其胰岛素敏感性的影响.方法 将体重指数>23 kg/m^2无药物及相关疾病的80例女性受试者,年龄35~55岁,分为西布曲明干预组和运动饮食干预对照组,每组40例,干预13周,观察干预前后受试者的体重、腰围、臀围、空腹、餐后2 h的血糖、胰岛素、糖化血红蛋白的变化.测定血清肿瘤坏死因子α、血清可溶性肿瘤坏死因子α受体Ⅱ指标的水平.应用稳态模形评估法评价胰岛素抵抗程度.结果 基线相关性分析显示,Homa IR与体重指数、腰围、腰臀比、OGTT-2 h血糖、胰岛素以及血清sTNF-αRⅡ呈正相关(r=0.86,0.65,0.67,0.36,0.76,0.56,P<0.05);与血清TNF-α水平无关(P>0.05);各组治疗前后,体重、体重指数、腰臀比、空腹血糖及胰岛素、OGTT-2 h血糖、Homa IR指数及STNF-αRⅡ均显著下降(P<0.05);血清TNF-α无明显变化(P>0.05).西布曲明组治疗后Homa IR和sTNF-αRⅡ分别为(0.79±0.40)ng/ml和(4.57±2.51)ng/ml,较对照组Homa IR(0.98±0.35)和sTNF-αRⅡ(4.78±2.97)ng/ml下降更为明显,但校正BMI和腰臀比后,两组之间Homa IR和sTNF-αRⅡ差异无统计学意义(P>0.05).结论 减轻体重可以通过降低血清sTNF-αRⅡ的水平,改善超重及肥胖者的胰岛素敏感性;西布曲明降低血清sTNF-αRⅡ、改善胰岛素抵抗的作用依赖于其减重效应.
