In patients with liver cirrhosis,variceal bleeding is a common fatal complication of portal hypertension.Varices are present in al-most half of patients with cirrhosis at the time of diagnosis.Since transjugular intrahepatic portosystemic shunt (TIPS)was first applied clini-cally in 1988,the relevant information about TIPS has been continually updated and perfected by lots of clinical trials.The role of TIPS in the prevention and treatment of variceal bleeding in cirrhotic patients with portal hypertension,including primary prevention of variceal bleeding,treatment of acute variceal bleeding,and prevention of rebleeding,is reviewed.TIPS is an effective treatment for variceal bleeding in cirrhotic patients with portal hypertension.Along with the technical development,TIPS will be available for more and more patients and will play an increasingly important role in the prevention and treatment of variceal bleeding among cirrhotic patients with portal hypertension.

Objective To investigate the multi-organ lesions and the occurrence of coronary aneurysms in children with Kawasaki disease(KD).Methods 92 pediatric inpatients with KD were enrolled and studied.The organs involved and coronary aneurysms(CAA)were determined by checking blood routine,urine routine,stool routine,chest X-ray,electrokardiogram,liver function,echocardiogram,and clinical manifestation.Results The incidence of various organs involved in 92 patients with KD:heart 71.7%;lung 37.0%;liver 34.8%;brain 12.0%;kidney 18.5%;gastrointestinal tract 15.2%;spleen 2.2%;gallbladder 1.1%;joints 9.8%.In addition,the rate of two organs involved simultaneously was 40.2%,three and more 34.8%.The incidence of CAA in brain lesion,joints lesion and pericardial effusion complications of KD was 45.5%,44.4%,and 41.7%,respectively.Conclusions The data shows that the incidence of heart involvement in the sick-children with KD is highest,and other organs,such as lung,liver,kidney,gastrointestinal tract,brain and joints are involved in turn.The incidence of 2 and more organs involved simultaneously amounts to75.0%.CAA is the most serious complication of KD.Our study suggests that the incidence of CAA is obviously high in these lesions of brain,joints and pericardial effusion involvement in KD.

Objective To explore a highly sensitive and highly specific method to detect the serum MG7 antigen (Ag) level for early gastric cancer diagnosis.Methods The serum MG7-Ag level was detected by enzyme-linked immunosorbent assay (ELISA) method in 116 preoperative gastric cancer patients,63 postoperative gastric cancer patients,41 patients with precancerous lesion,37 patients with precancerous diseases,50 healthy individuals and 281 patients with other cancers.Meanwhile,the expression of MG7-Ag was also examined with immunohistochemistry in patients with gastric cancer or precancerous lesion.Chi-square test was used for comparing positive rates of the two detection methods.Results The positive rate of MG7-Ag determined by ELISA was 83.6％(97/116) of preoperative gastric cancer patients,45.2％(28/62) of lung cancer patients,45.5％(20/44) of rectal cancer patients,17.6％ (12/68) of colonic cancer patients,14.2％ (6/42) of breast cancer patients,47.6％ (30/63) of postoperative gastric cancer patients,19.5 ％ (8/4 1) of patients with precancerous lesions,5.4 ％ (2/37) of patients with precancerous diseases and 0 of healthy individuals.The sensitivity of ELISA (83.6 ％) was similar with that of immunohistochemistry (94.0％)(P＞0.05).However,the false positive rate of ELISA (12.8 ％) was lower than that of immunohistochemistry (51.3 ％) (x2 =26.491,P＜0.01).There was statistically significant difference in MG7 Ag expression in gastric cancer with different clinical stages (x2=15.564,P＜0.01).Conclusion This ELISA method might be a non-invasive screening method for population with high risk of gastric cancer.
