摘要 目的:探讨凋膜止崩液宫腔靶向给药治疗无排卵性功能失调性子宫出血(功血)子宫内膜增生症的可能机制。方法:选取健康成年SD雌性大鼠48只,分为空白组、模型对照组、实验小剂量组和实验大剂量组,建立无排卵性功血子宫内膜增生症模型。凋膜止崩液宫腔内给药后3d处死,留取子宫标本,采用免疫组化技术检测各组大鼠子宫内膜组织中雌激素受体(ER)、ERα及ERβ的表达水平。结果:模型对照组ER、ERα、ERβ的表达高于空白组,实验大、小剂量组ER、ERα、ERβ的表达低于模型对照组,差异均有统计学意义(均P<0.001),实验大剂量组ER、ERα和ERβ水平低于实验小剂量组,差异有统计学意义(P<0.01)。结论:凋膜止崩液通过下调ER、ERα及ERβ阻断了雌激素发挥效应的通路,抑制子宫内膜的持续性增生从而治疗子宫内膜增生症。 Objective: To explore the role and the possible mechanism ot Diaomozhibeng liquid in rats with the endome- trial hyperplasia (EH). Methods: Forty-eight SD rats were divided into four groups including control group, model control group, the experimental low-dose group and the experimental high-dose group. The rat model of endometrial hyperplasia was induced with estrogen load. The Diaomozhibeng liquid was administrated in uterine cavity in rats. The expression levels of es- trogen receptor (ER), ERα and ERβ were checked by immunohistochemistry. Results: Compared with control group, expres- sions of ER, ERa and ERβ increased in rats of the model group (P 〈 0.001). However, after treatment with Diaomozhibeng liq- uid, the expression of ER, ERα and ERβ significantly decreased (P 〈 0.001). Expression levels of ER, ERα and ERβ were significantly lower in high-dose experimental group than those of low-dose experimental group (P 〈 0.05 or P 〈 0.01). Con- clusion: Diaomozhibeng liquid plays a role in endometrial hyperplasia by accelerating the ecclasis of uterine endometrial. One of mechanisms is maybe related to inhibiting the expression of ER, ERα and ERβ
