Effect of warming Yang and removing blood stasis method on matrix metalloproteinases / tissue inhibitor metalloproteinases levels secreted by cultured endometrial cells from patients with endometriosis

ObjectiveTo investigate the effect of Chinese medicines using the warming Yang and removing blood stasis method on levels of matrix metalloproteinases (MMPs)/tissue inhibitor metalloproteinases (TIMPs) secreted by cultured endometrial cells from patients with endometriosis.MethodsEctopic and eutopic endometrial cells obtaind from 15 endometriosis patients were cultured in vitro, and divided randomly into five groups: high dose; moderate dose; low dose; nemestran; blank control. The three dose groups were treated with a decoction prepared according to the principle of warming Yang and removing blood stasis; nemestran and 0.9% NaCl were administered to the nemestran group and balnk control group, respectively. Eutopic endometrial cells obtaind from 10 hysteromyoma patients were cultured in vitro, as the normal control group, 0.9% NaCl were administered to the normal control group. Cell culture supernatants were collected and levels of matrix metalloproteinase-1 (MMP-1), matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), tissue inhibitor metalloproteinase-1 (TIMP-1) and tissue inhibitor metalloproteinase-2 (TIMP-2) detected by enzyme-linked immuno sorbent assay (ELISA).ResultsCompared with the normal control group, levels of MMP-1, MMP-2, and MMP-9 in eutopic and ectopic endometrium cell supernatants in the blank control group were increased, whereas levels of TIMP-1 and TIMP-2 were decreased (P < 0.05). Compared with the blank control group, levels of MMP-1 and MMP-2 in ectopic and eutopic endometrium cell supernatants cultured in low-dose, middle-dose, and high-dose groups were decreased, whereas levels of TIMP-1 and TIMP-2 were increased significantly (P < 0.05).ConclusionThe warming Yang and removing blood stasis method affects expression of MMPs and TIMPs.
