- W3031330398 abstract "Objective To investigate the effect on the miemvnscular density(MVD)and the expression of vascular endothelial growth factor(VEGF)in VX2 tumor after transcatheter arterial chemoembolization(TACE)combined with endostatin.Methods The VX2 tumor model wag established.The rabbits bearing tunlor were randomly divided into three groups as the control group.TACE group and TACE combined with endostatin group.with 10 rabbits in each group.In the control group,normal saline was administered via the hepatic artery.In the TACE group,lipiodol(0.2 ml/kg)and ADM(2.g/kg)were administered.Lipiodol(0.2 ml/kg),ADM(2 mg/kg)and endostatin(2 mg/kg)were administered for each rabbit in the TACE combined with endostatin group.Seven days after operation,the rabbits were sacrificed and the tumors were removed.Immunohistochemistry wag performed to demonstrate the expression of VEGF and the MVD wag caleulated.The ANOVA wag used for statistics.Results The average absorbance values of VEGF were 0.130±0.038.0.200±0.049 and 0.120±0.047 respectively for the 3 groups.There was signiflcant difference among the three groups(F=9.42,P＜0.01).rnle expression of VEGF in the TACE group was the hiShest among the 3 groups.Compared with the otIler two groups,there had signifieant differences(q=4.93,5.63,P＜0.01).The average absorbance value of the TACE combined with endostatin group was lower than that of control group,but there was no significant difference between them(q=0.70,P＞0.05).The values of MVD were(80±17),(84±16)and(57±13)/HPF for the 3 groups respectivelv.There wag significant difference among them(F=8.70,P＜0.01).111e value of MVD in the TACE combined with endestatin group was the lowest, and there were significant differences when compared with the control group (q=4.63, P＜0.01) and the TACE group (q =5.48, P＜0.01).There was no significant difference between the control group and the TACE group (q = 0.85, P ＞ 0.05) in MVD.Conclusion Compared with chemoembolization only, ehemoembolization combined with endostatin can significantly depress the expression of VEGF and decrease the angiogenesis of the tumor.The combined method has a beneficial effect on prognosis of hepatic tumor.Key words: Liver neoplasm,experimental; Chemoembolization,therapeutic; Neovascularization,pathologic; Animal,laboratory" @default.
