Abstract:
Objective To study the effect of IFN-αcombined with ATRA in liver cancer therapy in perioperative phase of inter-vention .Methods An animal model of liver cancer CBRH7919 was established by implanting 28 Wistar rats with tumor tissue .The hepatic artery was tied off in one month after formation of tumor .All the rats were randomly divided into the experimental group (14 cases) and the control group(14 cases) .The control group accepted peritoneal injection with normal saline while the experimen-tal group accepted IFN-αcombined with ATRA .10 days later ,all the rats were sacrificed .And the level of expression of VEGF ,bF-GF ,mirovessel density ,and apoptotic index of tumor cells were measured .Results Serum VEGF level ,MVD and apoptotic index of tumor cells of the experimental group were statistically lower than that of the control group [(91 .8 ± 12 .7) pg/mL ,(115 .7 ± 11 .8)/HP ,(12 .29 ± 4 .53)% vs .(67 .4 ± 18 .3)pg/mL ,(65 .3 ± 7 .2)/HP ,(3 .81 ± 1 .52)% ,t=4 .099、13 .642、6 .640 ,P<0 .05)] , results of RT-PCR and immunohistochemistry detection both showed that the levels of expression of VEGF and bFGF of the exper-imental group was lower than that of the control group .Conclusion IFN-αcombined with ATRA in liver cancer therapy in periop-erative phase of intervention could suppress the generation of neoplastic vascular and improve the effect of the intervention .So it is worth promoting .
