摘要
目的:研究"消瘤颗粒"对雌孕激素负荷法建立的子宫肌瘤大鼠模型的干预及其作用机制。方法:以雌孕激素负荷法建立子宫肌瘤的大鼠模型,观察消瘤颗粒对模型大鼠子宫病理增生,肌瘤组织中孕激素受体(PR)、雌激素受体(ER)、Bcl-2/Bax表达的影响,从而探讨消瘤颗粒治疗子宫肌瘤的作用机制。结果:消瘤颗粒能抑制模型大鼠子宫平滑肌增生,能显着减少肌瘤组织中ER、PR、Bcl-2/Bax的含量。结论:消瘤颗粒是治疗子宫肌瘤的有效药物,其作用机制可能是通过拮抗子宫肌瘤的增生,减少ER、PR以降低对E、P的敏感性,降低Bcl-2的表达,增加Bax的表达,促进细胞凋亡等,达到治疗子宫肌瘤的目的。
Objective： Xiaoliu Granule （XLG） is based on the principle of Yiqi Huayu Decoction, this experiment was to study the treating point of XLG on the hysteromyoma rats. Methods： The hysteromyoma rats models was established in rats by loading estrogen and progesterone, to observe the effect of XLG on pathological condition of uterus, and the content of PR , ER, Bcl-2/Bax. Results： The experiments proved that XLG was effective in reducing the proliferation, reversing the proliferative abnormalities of uterus smooth muscle. The XLG also can significantly reduce the content of PR, ER and Bcl-2/Bax. Conclusion： Therefore, XLG was a good approach in treating hysteromyoma. The mechanism of XLG in treating hystermyoma was probably by reducing ER, PR, lowering the E, P sensitivity; reducing expression of Bcl-2, increasing the expression of Bax, and promoting cell apoptosis, etc.
