摘要
目的检测多囊卵巢综合征患者(PCOS)及正常人群血浆骨膜蛋白(periostin)水平变化,探讨其与胰岛素抵抗及肥胖的关系。方法收集初诊的PCOS患者68例(PCOS组),同时选择年龄及体质指数(BMI)匹配的正常育龄期女性72例(对照组),ELISA法测定两组的血浆periostin水平,比较periostin水平与相关生化指标水平,并探讨periostin与相关指标之间的关系,通过稳态模型(HOMA)评估胰岛素抵抗(HOMA-IR)。结果 PCOS组血浆periostin水平高于对照组[(32.5±5.5)vs(25.9±3.6)ng/mL,P<0.01],PCOS组及对照组超重或肥胖亚组血浆periostin高于正常体重亚组,相关性分析提示血浆periostin水平与BMI、腰臀比、空腹血糖、餐后2h血糖、空腹胰岛素、HOMA-IR、总胆固醇、低密度脂蛋白胆固醇呈正相关(P<0.01,P<0.05),以periostin水平为因变量行多元线性逐步回归分析提示BMI、HOMA-IR是血浆periostin水平的独立影响因素(P<0.01)。结论血浆periostin水平在新诊断的PCOS和超重或肥胖人群中升高,可能与胰岛素抵抗相关。
