The mice were randomly divided into five groups: model control group(C),Liuweidihuang pill high-dose group(LH; 4.6 g·kg1·d1),Liuweidihuang pill low-dose group(LL;2.3 g·kg1·d﹣1),Jinkuishenqi pill high-dose group(JH; 4.6 g·kg﹣1·d1) and Jinkuishenqi pill low-dose group(JL;2.3 g·kg﹣1·d﹣1). Cancer tissue volume was measured by water immersion. Histopathology was analyzed by hematoxylin and eosin staining. Vascular endothelial growth factor(VEGF),extracellular signal-regulated kinase(ERK) and cyclin D1 protein expression in cancer tissue was assayed by western blotting.RESULTS: Compared with the control group,cancer tissue volume and weight were lower in the LP and JP groups,and survival time was longer. The expression of VEGF,ERK and Cyclin D1 were inhibited in the LP and JP groups(P < 0.05),and cell differentiation was increased. Tumor weights and volumes and VEGF,ERK and Cyclin D1 expression in LL or LH were significantly lower than in JL and JH(P < 0.01).CONCLUSION: Both LP and JP could restrain cancer growth and promote cancer cell differentiation;moreover,LP was more effective than JP The likely mechanism of action was via inhibition of VEGF,ERK and cyclin D1.展开更多
