Abstract:
Background and purpose:The growth,metastasis,relapse and the prognosis of tumor are correlated with tumor angiogenesis.Therefore,target to angiogenesis and antiangiogenic therapy has become one of the hot points in cancer research field.Some chemotherapeutic drugs can inhibit the growth of new vascular endothelial cell markedly in the way of low-dose and high time administration.This is metronomic chemotherapy or antiangiogenic chemotherapy.Traditional Chinese medicine has an effect on tumor control.In recent years,we discovered that some traditional Chinese medicine have an antiangiogenic effect.This experiment aimed to study the antiangiogenetic ability of oxaliplatin combined with composite radix sophora flavescentis injection(CRSFI) in vitro and in vivo. Methods :We used MTT method to observe the influence of oxaliplatin and composite radix sophora flavescentis injection on human umbilical vein endothelial cells(HUVEC) or LoVo proliferation.The influence of oxaliplatin and composite radix sophora flavescentis injection on HUVEC migration was evaluated by transwell.Chick embryo chorioallantoic membrane(CAM)model was used to check whether the neovascularization of CAM could be suppressed in vivo by them. Results :The survival rate of LoVo within the same doses of oxaliplatin and composite radix sophora flavescentis injection were higher than HUVEC.Oxaliplatin(2 ?g/ml) and composite radix sophora flavescentis Injection(25 ?l/ml) could inhibit the prolifetation of HUVEC;the rate of inhibition were 31.6%,32.1% respectively;the rate of the two drugs combination was 54.4%.So when combined,they had synergistic effect.There was coordinate repression to migration of HUVEC in vitro when we used oxaliplatin(0.5 ?g/ml) and composite radix sophora flavescentis injection(6.25 ?l/ml).They also suppressed angiogenesis of CAM in vivo. Conclusions :This experiment showed that low dose oxaliplatin combined with composite radix sophora flavescentis injection has anti-angiogenic synergetic ability in vivo and the ability of inhibiting the growth of the cells in vitro.
