For recent two decades,radiofrequency ablation technology(RFA)has made great progress in the field of the treatment for diseases for its distinguishing characteristic of microtrauma,targeted,effective and almost having no side-effect.At the very beginning,radiofrequency ablation was adopted in treating solid tumors,and since then it has been gradually practiced in treating benign diseases of solid organs such as hypersplenism,prostatic hyperplasia and widely used in almost every system of the body.Here,we review its therapic principle,types and clinical application.

Objective To investigate the apoptosis of gastric carcinoma SGC-7901 cell induced by histone deacetylase inhibitor(TSA)and to clarify its mechanisms.Methods The apoptosis-inducing role of TSA on gastric carcinoma SGC-7901 cell was investigated with the help of cell proliferation assay,Annexin V stain,cell flow analyzer and Tunel assay.Western blot,gene chips,real time PCR were employed to study the influence and mechanisms of TSA on the expression of gastric carcinoma cell SGC-7901 p53,bax,etc.Results TSA could induce the apoptosis of gastric carcinoma SGC-7901 cells,increase the expression of p53 and bax,and decrease the expression of bcl-2.survivin and easpase in gastric carcinoma SGC-7901 cells.TSA could transfer AIF and EndoG from mitochondria to nucleus.The apoptosis induced by TSA was brought about through the regulation of multiple apoptosis-related genes,and the apoptosis pathway induced by TSA was caspase-independent.Conclusion TSA can induce caspase-independent apoptosis in gastric carcinoma SGC-7901 cell through the regulation of multiple apoptosis-related genes.

Objective To evaluate the effectiveness and safety of interventional thermochemotherapy for VX2 transplanted hepatic tumor model in experimental rabbits.Methods The hepatic tumor model was established in 20 New Zealand rabbits by implanting VX2 tumor cells into the right hepatic lobes of the rabbits.The rabbits were randomly and equally divided into two groups with 10 rabbits in each group:group A (study group)and group B(control group).Via the femoral access,the catheter was placed into the tumorfeeding artery,which was confirmed by DSA.The rabbits in group A received an infusion of 100 ml 5% glucose plus 5-Fu(20 mg/kg)at 60℃ temperature,while the rabbits in group B received an infusion of 100 ml 5% glucose plus 5-Fu(20 mg/kg)at normal room temperature(22-25℃).Before and after the procedure,the tumor size was measured by means of B ultrasonography and the serum ALT was estimated to assess the liver function.The results were statistically compared between two groups.Results After the treatment,the tumor size in group A(study group)became much smaller than that in group B(control group),with P＜0.05.And no significant difference in the serum ALT level existed between group A and group B.Conclusion The interventional thermochemotherapy is superior to interventional chemotherapy in inhibiting VX2 transplanted hepatic tumor in experimental rabbits.
