Jiedu Yiqi Huoxue Fang On Human Umbilical Vein Endothelial Cells Angiogenesis And Stat3 Signaling Pathway Intervention Study

ObjectiveStudy on detoxification methods of Qi-live on human umbilical vein endothelial cells on angiogenesis and study on intervention of STAT3signal transduction and MMP-2.MothodsHUVEC cultured in vitro, different concentrations of a poison after exposure to animal sera of Yiqi huoxue recipe on HUVEC, observation of endothelial cell tube formation experiments, take pictures and observation of angiogenesis inhibition using immunohistochemical detection of STAT3expression in cells by immunohistochemical method and detection of MMP-2expression in cultured cells. Detoxication of supplementing Qi and activating blood circulation and discussion on effect of human umbilical vein endothelial cells on angiogenesis, and effects on expression of STAT3in HUVEC and MMP-2.Results1、Angiogenesis effect of HUVEC, medication HUVEC tube index significantly below the blank control group (P<0.05or P<0.01), especially in the detoxication of Yiqi huoxue prescription in serum of animals, high dose group clearly. Detoxication of Yiqi huoxue prescription in serum of animals, high dose group compared with the5-FU Group also has significant differences (P<0.05). Indicates that a poison Yiqi huoxue prescription in serum of animals, high dose group significantly suppress HUVEC angiogenesis.2、Effect on the expression of STAT3, STAT3-positive cells light blank control groups values are higher, the optical density values were group positive cells of drug use is significantly lower than the blank control group (P<0.05,P<0.01), compared with the5-FU group, detoxication of Yiqi huoxue prescription in serum of animals, and significant reduction in the high-dose group (P<0.05,P<0.01). Group indicates that the medication can reduce the expression of STAT3, with the detoxication of Yiqi huoxue prescription in serum of animals, high dose group are most apparent. 3、Effect on the expression of MMP-2, blank control group MMP-2positive cells in optical density values are higher, the optical density values were group positive cells of drug use is significantly lower than the blank control group (P<0.05,P<0.01), compared with the5-FU group, detoxication of Yiqi huoxue prescription in serum of animals, and significant reduction in the high-dose group (P<0.05,P<0.01). Group indicates that the medication can reduce the expression of MMP-2. with the detoxication of Yiqi huoxue prescription in serum of animals, high dose group are most apparent.Conclusions1、Detoxication of supplementing Qi and activating blood circulation can inhibit angiogenesis in HUVEC and concentration are related to medicine. Detoxication of supplementing Qi and activating blood circulation can be adopted to prevent tumor recurrence and metastasis of tumor angiogenesis.2、he STAT3expression in HUVEC and detoxication of animal serum concentrations of Yiqi huoxue recipe-related, and with negative correlation to concentration.3、MMP-2expression in HUVEC and detoxication of animal serum concentrations of Yiqi huoxue recipe-related, and with negative correlation to concentration.
