TITLE: Study on mechanism of action of Fuke duanhongyin capsule on the improvement of dysfunctional uterine bleeding in rats
摘要: 目的 研究妇科断红饮胶囊改善大鼠功能失调性子宫出血(DUB)的作用机制。方法按照随机数字表法将SD孕鼠随机分为空白对照组(蒸馏水)、模型对照组(蒸馏水)和妇科断红饮胶囊组(1.296g/kg),每组6只。除空白对照组外,其余组大鼠均构建DUB模型。造模成功后,大鼠灌胃相应药液/蒸馏水,灌胃体积均为10mL/kg,每天1次,连续14d。灌胃结束后,检测大鼠子宫指数、卵巢指数和血液流变学指标(全血高切相对指数、全血低切相对指数、红细胞聚集指数、卡松黏度),观察大鼠子宫和卵巢组织病理形态变化并检测子宫组织中表皮生长因子(EGF)、低氧诱导因子1α(HIF-1α)、表皮生长因子受体(EGFR)、丝氨酸/苏氨酸蛋白激酶1(AKT1)mRNA相对表达水平和EGF、EGFR蛋白相对表达水平。结果与模型对照组比较,妇科断红饮胶囊组大鼠子宫指数、卵巢指数、红细胞聚集指数均显著降低(P<0.05或P<0.01),全血高切相对指数及子宫组织中EGF、HIF-1α、EGFRmRNA相对表达水平和EGF、EGFR蛋白相对表达水平均显著升高(P<0.05或P<0.01);大鼠卵巢组织和子宫组织的病理变化得到改善。结论妇科断红饮胶囊改善大鼠DUB的作用机制可能与激活EGF-EGFR信号通路有关。
ABSTRACT: OBJECTIVE To investigate the mechanism of Fuke duanhongyin capsule in improving dysfunctional uterine bleeding (DUB) in rats. METHODS Pregnant SD rats were randomly divided into blank control group (distilled water), model control group (distilled water) and Fuke duanghongyin capsule group (1.296 g/kg), with 6 rats in each group. Except for blank control group, DUB model was established in other groups. After modeling, they were given relevant medicine/distilled water 10 mL/kg intragastrically, once a day, for consecutive 14 d. After medication, uterine index, ovary index and hemorheology indexes (whole blood high shear relative index, whole blood low shear relative index, erythrocyte aggregation index, Carson viscosity) of rats were all determined. The pathological changes of uterus and ovary tissues were observed; mRNA relative expression levels of epidermal growth factor (EGF), hypoxia-inducible factor 1α (HIF-1α), epidermal growth factor receptor (EGFR) and serine/ threonine-protein kinase 1(AKT1), and protein relative expression levels of EGF and EGFR in uterine tissue were all measured. RESULTS Compared with model control group, the uterine index, ovary index, erythrocyte aggregation index were all decreased significantly in Fuke duanghongyin capsule group (P<0.05 or P<0.01); whole blood high shear relative indexes, mRNA relative expression levels of EGF, HIF-1α and EGFR and protein relative expression levels of EGF and EGFR in uterine tissue were all increased significantly (P<0.05 or P<0.01). The pathological changes of ovary and uterus were improved. CONCLUSIONS Fuke duanhongyin capsule can improve DUB in rat, the mechanism of which may be related to the activation of EGF-EGFR signaling pathway.
