ABSTRACT
Transjugular intrahepatic portosystemic shunt (TIPS) is now considered as a major treatment option for cirrhotic patients with portal hypertension. Globally, it is getting markedly increase attention, and a similar phenomenon is occurring in China. On average, the number of TIPS procedures is increasing at a rate of 15% per year. Published research papers are also continuously growing every year. Similar but unique compared to western countries, most Chinese physicians follow Chinese specialized guidelines when treating patients with portal hypertension. In this review, we briefly introduce the history of TIPS in China, the present and the future of TIPS in China.

Objective To study the of effets of hFRNK gene transfected by adenoviral vector on human colon cancer cell invasion induced by gastfin.Methods The subjects were divided into three groups:control,G17 and hFRNK group.The G17 group was treated with 100 umol/L gastrin 17 for 12 h to induce Col0320WT cells.As to hFRNK group,Colo320WT cells were infected by pAdhFRNK(MOI:100)for 48 h after transient transfection of pCR3.1-CAR for 48 h and subsequently treated with gastrinl7 for 12 h,and the control group was untreated Colo320WT cells.Expression of phosphorylated FAK(PY397)were assayed by western blot.FAK(PY397)at lamellipoda was observed with a confocal microscope.The influence of hFRNK on formation of signal complex of FAK-Src-p130Cas-Dockl80 was assayed with coimnlunoprecipitation and immunity blotting.Activity of Rac-GTPase was determined by pull down.Results Phosphorylated FAKTyr397 drastically increased with the induction of gastrin.Compared with that of G17 group,FAK (PY397)expression decreased and little FAK(PY397)was found at lamellipoda,at the same time,the signal complex of FAK-Src-p130Cas-Dockl80 did not form,and the activity of Rac decreased.Conclusion hFRNK gene may block gastrin-induced FAK phosphorylation,prevent formation of the signal complex,prevention and treatment of tumor invasion and metastasis.
