ABSTRACT
Objective To study the effects of apoptosis of the tumor cells in rabbit liver VX2 carcinoma after treatment by radiofrequency ablation(RFA) combined with trans arterial chemoembolization(TACE) and high‐frequency hyperthermia(HFH) . Methods Rabbit liver VX2 carcinoma model was established .Rabbit liver VX2 tumor models were divided into the following groupgroup A ,RFA+ TACE;group B ,RFA + TACE + HFH ;group C ,RFA + HFH ;group D ,TACE+ HFH .The changes of serum ALT was detected to realize the safety of the treatment .Cell apoptosis were detected by DNA agarose gel electrophoresis and terminal deoxynucleotidyltransferase‐mediated Dutp nick end‐labeling(TUNEL) assay ;SP immunohistochemistry ,Western blot and Real‐time quantitative PCR(RT‐PCR) were used to detect Caspase‐3 protein and mRNA expression levels .Results The changes of serum ALT in group B was significantly higher .Compared with other groups ,the apoptosis index in group B was increased marked‐ly(P<0 .05) .Western blot and RT‐PCR Caspase‐3 protein and mRNA levels in group B were higher than the other groups(P<0 .05) .Conclusion RFA+ TACE+ HFH can effectively kill tumor cells and promote apoptosis of tumor cells ,but ,at the same time ,can damage liver function .
