摘要 目的:探讨左炔诺孕酮宫内缓释系统(LNG-IUS)对增生过长子宫内膜胰岛素样生长因子(IGF)的影响。方法:应用免疫组化链霉亲和素-生物素-过氧化物酶复合物(SABC)方法分别对20例子宫内膜增生过长患者宫腔内置入LNG-IUS前及置入3个月后子宫内膜IGF-I和IGF-II的表达及20例口服炔诺酮3个月后的增生过长宫内膜IGF-I和IGF-II的表达。结果:与治疗前比较,增生过长的子宫内膜宫腔内置入LNG-IUS3个月后,IGF-I表达下降,IGF-II的表达上升(P均<0.05)。LNG-IUS治疗后子宫内膜IGF-I表达下降比炔诺酮治疗后的子宫内膜IGF-I表达下降明显,两者比较差异有显著性(P<0.05),IGF-II在LNG-IUS治疗后的子宫内膜的表达高于炔诺酮治疗后的子宫内膜,间质细胞尤为明显,但统计学无显著性意义。结论:LNG-IUS可通过下调增生过长子宫内膜IGF-I表达及上调IGF-II的表达促使子宫内膜分化,逆转增生过长现象。
