摘要 目的研究多囊卵巢综合征(PCOS)患者血清脂联素(APN)、瘦素(LEP)改变与胰岛素抵抗(IR)的关系。方法按体重指数(BMI)将PCOS患者104例分为肥胖组(67例)和非肥胖组(37例),随机选择健康体检的护士作为正常对照组(28例),检测性激素[包括促卵泡生成素(FSH),黄体生成素(LH),睾酮(T)]、血糖(FBG)、胰岛素(FINS)、LEP和APN等指标,并计算体重指数(BMI)、胰岛素抵抗指数(HOMA—IR),采用软件SPSS13.0行组间比较的方差分析,组间两两比较的q检验(SNK法),APN,LEP与各指标的Pearson相关性分析,形成HOMA—IR主要因素的多元逐步回归分析。结果①方差分析显示PCOS伴肥胖组BMI,LH/FSH,T,FINS,LEP,HOMA—IR均高于对照组(P〈0.01),APN低于对照组(P〈0.01);PCOS非肥胖组LH/FSH,T高于对照组(P〈0.01),LEP,HOMA—IR高于对照组(P〈0.05),BMI,APN低于对照纽(P〈0.05);两组FINS,差异无统计学意义(P〉0.05);两病理组中肥胖组BMI,FINS,LEP,HOMA-IR均高于非肥胖组(P〈0.01),APN低于非肥胖组(P〈0.05).两组LH/FSH,T差异无统计学意义(P〉0.05)。②Pearson相关性分析PCOS患者血清APN与BMI,FINS,HOMA—IR呈负相关(r=-0.52,-0.44,-0.49,P〈0.01),血清LEP与BMI,FINS,HOMA—IR呈正相关(r=0.41,0.32,0.35,P〈0.01),血清APN,LEP与LH/FSH比值及T无显著相关性(P〉0.05);血清APN与LEP呈显著负相关(r=-0.62,P〈0.01)。多元逐步回归分析显示BMI,APN,LEP是形成HOMA—IR的主要因素。结论PCOS患者存在低APN,高LEP血症和胰岛素抵抗,且相互之间密切相关;血清APN,LEP含量可作为PCOS患者的辅助诊断指标。
