【Abstract】Objective: To study and analyze the application of mifepristone in the treatment of gynecological tumors. Methods: The mechanism of mifepristones anti-gynecological tumor, treatment principle and effect, and treatment recommendations were analyzed. RESULTS: Mifepristone belongs to the class of antiprogestin drugs, which is used in uterine induction and gynecological procedures, such as placement and removal of IUDs, removal of endometrial specimens, laser separation of cervical dysplasia, cervical dilation and curettage. Be aware of self-care and pay attention to diet when taking medication. Conclusion: The application of mifepristone in the treatment of gynecological tumor patients can effectively improve the treatment situation, and has obvious effects on uterine fibroids, breast cancer, cervical cancer, endometrial cancer and ovarian cancer.

米非司酮(mifepistne,RU486),作為一種抗孕激素類藥,自1980年初次生成并運用于臨床醫學至今,米非司酮在醫藥方面的使用取得了的發掘和推進。現階段RU486己變成婦科腫瘤治療的常備藥品,還被用以避孕、引產手術及其子宮肌瘤、內膜異位、婦科病變紅腫、腦膜瘤、膠質瘤、前列腺腫瘤等疾病的治療。本文就分析RU486治療婦科癌癥方面的研究現狀作一具體分析。
RU486主要功用是抗孕激素和糖皮質激素治療,但在一定情況下,它也展示出孕酮樣效果及其抗雌激素的特點。RU486的抗孕效果通過與孕激素受體(progesterone receptor,PR)結合而充分發揮。
據Rolbin報導,人體PR結構分子中有3個功能分區∶轉錄活性區,DNA結合區,激素結合區。當孕激素(progesterne,P)進到體細胞與PR結合后,R轉型發展,釋放出來熱休克蛋白,隨后產生二聚體,進而與DNA上相對應生長激素反應因素(hormone responsive elemen,HRE)結合,運行轉錄活化因子,進而通過mRNA生成蛋白質,產生激素效用。……
