Balloon tamponade hemostasis has been applicated for 50 years,and its appropriate usage can obtain exact curative effect with less adverse reactions.In recent years,with the continuous improvement in surgical therapy,balloon tamponade technique in treating various types of bleeding has accumulated many successful experiences.This paper intends to review the advances in balloon compression technology for recent years.

Objective: To investigate the relationship among personality traits,motive of Internet use and tendency of Internet Addiction.Methods: Scale of Internet use,NEO-PI-R and Chinese Internet Addiction Scale(CIAS) were administrated to 207 university and high school students.Results: ①Tendency of Internet addiction was significantly correlated positively with openness(O)and agreeableness(A),and negatively with neuroticism(N).②Tendency of Internet addiction showed significant difference among motive of entertainment,study,information and intercommunication,and those who had higher tendency of Internet addiction would have stronger motive.③Internet addiction could be validly predicted by motive of information,entertainment and personality traits of neuroticism(N).Conclusion: Tendency of Internet addiction is affected by personality traits and motive of Internet use.

Long-term outcomes of surgical bile duct injury (BDI) repair are affected by multiple factors, such as surgeon's experience, severity of BDI, pathological changes of the proximal duct, and the manner and timing of surgical repair. However, the timing of BDI repair is still controversial still. In this article, the authors reviewed the correlation of pathophysiologic changes of the proximal duct, repair timing and outcome discussed in English references. It was shown that pathophysiologic changes of the proximal duct are a major contributor to the timing of BDI repair.

It is a consensus to place stent after cutting bile duct in the hepatobiliary surgery in the past.However,as the development of bile physiological research and surgical technique,especially the raise of medical concepts of rapid recovery,the negative effects which are caused by the placement of stent have been taken seriously gradually.Up to now,whether the stent should be placed after the bile duct is cut has no definite answer yet.

Objective To evaluate the effect of omeprazole in preventing treatment of hypertensive cerebral hemorrhage with stress ulcer bleeding. Methods A total of 100 patients with hypertensive cerebral hemorrhage were treated with conventional therapy including dehydration, antihypertensive and supporting treatment. The patients were randomly divided into omeprazole group(n=50) and control group( n = 50). The control group received conventional therapyonly, while the omeprazole group received additional omeprazole 40mg, iv, qd, for 14d. Results Omeprazole group stress ulcer 6 eaess(12.0% ) was significantly lower than the control group 12 cases(24.0% );two groups stress ulcer incidence of severity are increasing with the increase of the disease; the mortalities of cerbral hemorrhage were 6.0 % in the omeprazole group and 16.0 % in the control group and the difference had significant meaning(P＞0.05). Conclusion Omeprazole has significant beneficial effect in preventing upper gastrointestinal hemorrhage after hypertensive cerebral hemorrhage.

In order to elucidate the mechanism of liver damage due to acute biliary sepsis,the changes of hepatocyte mitochondria were observed during biliary sepsis in the rat.The accompanied liver function changes were also studied.Mitochondrial calcium content,and lysosome fragility of the hepatocytes,lipid peroxide (LPO) level of liver tissue,ornithine carbamoytransferase (OCT),mitochondrial glulamicoxloacetic transaminase (m-GOT),and hepa-toplastin were determined.It was found that there were overloading of calcium in mitochondria,increase of lysosome fragility,and accumulation of LPO in the liver.These events would result in adverse effects on mitochondrial function.The activity of serum OCT and m-GOT was significantly increased,which suggests that mitochondria are seriously damaged since the 2 enzymes mainly come from hepatocyte mitochondria.And the liver reserving function declined progressively.Our study indicates that mitochondrial damage does exist during acute biliary sepsis,which might play an important role in liver damage.

The phagocytic function of Kupffer cells (KC) during acute obstructive cholangitis was observed in 244 Wistar rats.The rats were killed in the 6th,12th,24th,and 48th hour after operation,and the uptake of colloidal carbon by KC,plasma endotoxin and fibronectin(Fn)were determined and the morphology of KC was observed.It was found that in the rats with acute obstructive cholangitis,the phagocytic function of KC and plasma Fn significantly elevated in the 6th hour and markedly reduced in the 48th hour after operation as compared with those of the control (P

The changes of acid phosphatase(ACP)and cytochrome oxidase(CO)in the hepatic acini were investigated with image analysis in 90 Wistar rats after acute obstructive cholangitis was inflicted.It was found that the activity of ACP was significantly increased in the 2nd hour after surgery and markedly decreased in the 12th hour and these changes were predominantly located in acinur zone 1 of the hepatocytes.The activity of CO was decreased progressively after surgery,and these changes were quite marked in the acinur zone 3 of the hepatocytes.These findings indicate that the reactions towards acute obstructive cholangitis are different in the different acinur zones of the hepatocytes.

To investigate the value of tissue polypeptide specific antigen(TPS) in the diagnosis of hepatocellular carcinoma (HCC), the serum levels of TPS and alfa fetoprotein (AFP) were measured by TPS TM ELISA and enzyme immunoassay respectively in 96 patients with HCC, 30 patients with cirrhosis, 20 patients with hepatitis and 20 healthy controls.The diagnostic sensitivity of TPS and AFP is 89 6% and 73 0% respectively.There is a significant difference between them ( P

To investigate the expression of cytokeratin 18(CYK18) in hepatocellular carcinoma(HCC) cell membrane and the relationship between the serum levels of tissue polypeptide specific antigen (TPS) and the proliferating activity of HCC cells. The serum levels of TPS were determined by TPS TM ELISA in 96 patients with HCC. Four micrometer paraffin embeded sections of liver specimens from these patients were immunostained with the strept avidin biotin complex immunoperoxidase technique (IHC SABC). All of the HCC preparations were positively stained by CYK 18 and proliferating cell nuclear antigen (PCNA) with IHC SABC.The results of PCNA stainings were: + in 62 5%, in 26 0%,  in 8 3%,and  in 3 1% .The median levels of TPS in the four groups were: + 137 98 U/L,  685 3 U/L,  in 1 126 U/L and  4 672U/L respectively. There were significant differences among these groups ( P
