摘　　要：Objective This study aimed to investigate the effect of combretastatin A4 phosphate(CA4P)on proliferation,migration,and capillary tube formation of human umbilical vein endothelial cells(HUVECs)and the efficacy of transcatheter arterial embolization combined with CA4P in the treatment of rabbit VX2 liver tumor.Methods The effects of different concentrations of CA4P on proliferation,migration and capillary tube formation of HUVECs were investigated by cell proliferation assay,wound healing assay and capillary tube formation assay,respectively.Thirty-two rabbits implanted with liver VX2 tumors were randomly divided into 4 groups.After catheterization of the left hepatic artery,the infusion was performed using normal saline(group A),CA4P aqueous solution(group B),lipiodol and polyvinyl alcohol particles(group C),and CA4P lipiodol emulsion and polyvinyl alcohol particles(group D),respectively.Half of the animals in each group were euthanized for immunohistochemical analysis to evaluate microvessel density(MVD)at 3 days post-treatment.The other half were examined by MRI and histology to evaluate tumor growth and necrosis at 7 days post-treatment.Results CA4P could inhibit the proliferation,migration,and tube formation of HUVECs in cell experiments.After interventional treatment,the level of MVD in group D was lower than that in group C(P<0.01).The tumor volume in group C or D was lower than that in group A or B(P<0.01).The tumor necrosis rate was higher in group D than in the other groups.Conclusion The study suggests that CA4P could inhibit the proliferation,migration,and capillary tube formation of HUVECs,and transcatheter arterial embolization combined with CA4P could inhibit the growth of VX2 tumor and obviously induce tumor necrosis.
