Methods: A total of 60 female Wistar rats were randomly divided into 4 groups, namely, normal group, model group, positive group and TQD group, each group having 15 rats. Except the normal group, EMs model was established in the other three groups by transplanting the rat autologous endometrium. After 4 weeks of intragastric administration, blood, eutopic and ectopic endometrial tissues of rats in each group were collected to detect the serum levels of estrogen(E2), cancer antigen 125(CA125), endometrial antibody(EMAb), and expressions of microvessel density(MVD), vascular endothelial growth factor(VEGF) and angiopoietin(Ang-2). The volume of endometriosis cyst was determined simultaneously. For the in vitro culture of human endometrial cells, 4 groups, namely, normal group, model group, positive group and TQD group were used. The positive group and TQD group were treated with danazol and TQD respectively. Then 24 h after the treatment, the expressions of survivin and tumor suppressor gene(p53) of each group were detected. Results: The volumes of the endometriosis cysts in the positive group and the TQD group were significantly reduced compared with the model group(P<0.05). The serum levels of E2, CA125 and EMAb, and the expressions of MVD, VEGF and Ang-2 in the model group were significantly increased compared with the normal group(P<0.05); while they were all significantly reduced in the positive group and TQD group(P<0.05). Compared with the normal group, the expression of survivin in the model group was significantly upregulated(P<0.05), and expression of p53 was significantly reduced(P<0.05); compared with the model group, the expressions of survivin in the positive and TQD groups were significantly decreased(P<0.05), and expression of p53 was significantly up-regulated(P<0.05). The difference between positive group and TQD group was not statistically significant(P>0.05). Conclusions: TQD has a significant anti-EMs effect, and its mechanism of action may be related to anti-angiogenesis and promoting apoptosis of ectopic endometrial cell.展开更多
