Objective To study the 6 year outcome following transjugular intrahepatic portosystemic shunt (TIPSS) for variceal bleeding due to portal hypertension. Methods 65 patients, 51 males, 14 females, aged 35～72 years old with averaged 4.5 years, have been undergone TIPSS because of portal hypertension due to cirrhosis or Budd Chiari syndrome. The portal pressures were measured before and after TIPSS. Follow up study was done by color Doppler sonography or Barium esophageal radiogaphy for 3 months to 6 years (averaged 18 months). Repeated interventional treatments were done in cases of restenosis of the shunts. Results There were 0,2,10,5,0 cases of recurrent bleeding after 3 months, 6 months, 1 year, 2 year and 3—6 year following TIPSS respectively. Stenosis occurred in shunt paths due to thrombosis or smooth muscle cell proliferation or neointimal hyperplasia were relieved after thrombolytic therapy and repeated balloon angioplasty or stent plant among most of them. 2 were failed due to serious stenosis. 7 cases died, 2 of massive bleeding, 1 of the other cause and 4 of hepatic cancer. The other patients are getting well. Conclusions Although there were very high rates of restenosis (34%), but most of them could be treated again with interventional therapy, and in kept patency effectively. TIPSS is a still practical valuable management for massive gastric bleeding.

Objective To investigate the effects of colon hydrotherapy on lowering body temperature and serum enzymes as well as inflammatory cytokines of dogs with heat stroke.Methods 14 dogs were randomly devided into 2 groups,7 for each,as colon hydrotherapy group and conventional therapy group.After the reproduction of heat stroke model was finished(core temperature reached 43℃,maintaing for 10min),cooling therapy was commenced on dogs in circumstance with temperature at 23℃ and 65% of humidity.Conventional therapy group was lowered temperature by ice bags placed on conducting arteries,and the colon hydrotherapy group was by colon way therapeutic machine,the temperature of therapeutic liquid was maintained between 37℃~38℃.Cooling was finished while temperature in dogs reduced to 38℃.The periods of time for lowering body temperature in both groups were compared.Alanine aminotransferase(ALT),aspartate aminotransferase(AST),lactate dehydrogenase(LDH)and creatine kinase(CK)were determined before heat stroke(0h),and 6h,24h and 48h after heat stroke.Interleukin-1?(IL-1?),Interleukin-6(IL-6)and tumor necrosis factor ?(TNF-?)were determined by radioimmunity assay.Results Body temperature lowering time in dogs with colon hydrotherapy were 92.9?9.5min,which was significantly shorter than that of conventional therapy group(123.4?11.6min,P0.05).IL-1? in colon hydrotherapy group at 6h,24h and 48h after treatment were significantly lower than those in conventional therapy group(P
