Biliary atresia(BA) is a destructive inflammatory obliterative cholangiopathy of neonates affecting both intrahepatic and extrahepatic bile ducts.BA is more common in east Asia.Genetic susceptibility,viral infections,and immune dysregulation may be related to BA,but immune dysregulation may play a key hole in the pathogenesis of BA.A current view of the pathogenesis of BA is that it may involve both a primary perinatal hepatobiliary viral infection and a secondary generation of an autoimmune-mediated bile duct epithelial injury.The etiology of BA is unknown,but there is evidence for the involvement of immunologic dysregulation mechanisms,which will be discussed in this review.

Anorexia of aging is one of the common clinical geriatric syndrome in clinic, characterized by the persistent and significant decreasing of appetite and/or by reducing a food intake in the elderly, which can cause various adverse consequences and increase the morbidity and mortality.However, clinicians have insufficient understanding of anorexia in the elderly, and often regard the anorexia of aging as the normal phenomenon of aging and might ignore it.This article reviews the domestic and foreign relevant literatures on anorexia of aging.

Objective:Tumor common antigen of an extract of plant and applying in early stage diagnosis for tumor were studied.Methods:Tumor cells and lymphocytes proliferate responses were determined by 3H-TdR intervening.Fresh tumor tissue from human transplant to mice,the survival rate of transplanted tumor was observed.DNA content of tumor cells was measured by flowcytometery.The chemical nature was analyzed by chromatography and measured by ultraviolet-spectrometer.Results:The extract of plant markedly stimulated the lymphocytes from tumor patients and atypical hyperplasia patient to proliferate,but failed to health persons(P

Objective To elucidate the functional changes of E-cadherin (ECD) and ?-Catenin in the process of invasion and metastasis in renal cell carcinoma (RCC). Methods The expressions were investigated in 41 RCC by immunohistochemical staining of SP methods. Results Decreased expression of ECD and ?-Catenin correlate with the progression and higher clinical stage and poorer outcomes (P

WHO has issued three editions of pathologic classification of bladder urothelial carcinoma in 1973,1999 and 2004.The 1973 version classification had been widely and the longest applied.However,WHO 2004 classification had been prevalent in past years.There were two issues in the applications of WHO 2004 classification.On one hand,there were some difficulties in quick grading in a given case.On the other hand,there were some misunderstandings in the conversion of different WHO classification.In this article,the changes of different pathologic classification of bladder urothelial carcinoma were reviewed and the outline of different pathologic classification was generalized.The criterion of all the systems was cell anaplasia.In WHO 1973 version classification,the definition of the various grades was vague.It was relatively precise in WHO 1999 classification.However,the grading of Ⅰ,Ⅱ and Ⅲ in WHO 1999 classification still remained confusions.The major changes in WHO 2004 classification was that this system divided urothelial carcinoma into low-and high-grade,which may solve the heterogenesis of grade Ⅱ in the other two classifications.

In the future,anti-ship missiles(ASM) will be major weapons in the sea war.It is very important to handle the profile of the casualties aboard warships attacked by ASM for development of naval health service.The statistical result shows there is a greater chance of casualties but less chance of warships being sunken by ASM.Besides,medical staffs should pay more attention to the first aid for victims due to blast,burn,smoke inhalation and penetration while the danger of the sea water immersion should not be ignored.

To meet the needs of serving the general strategy,the central work and hospital development,the CCP committee of Beijing Municipal Administration of Hospitals has innovated and improved the leadership of the CCP building,and promoted the model at public hospitals by formulating and announcing the Indicators System for Municipal Public Hospitals ’ Party Building Performance Evaluation.This implementation aims to to guide,regulate and encourage the CCP work,which proves effective enhancement of the CCP building in municipal hospitals in terms of quality,efficiency,and effectiveness.

Aim To observe the timed analgesic effects by butabital (B), acetaminophen(A) and caffeine (C) in combination (BAC), in which the proportion was fixed as1. 25∶ 8. 1∶1. Method Three types of experimental methods, including the tailflicking method, the hot plate method and the pressurizing tail method, weretaken to determine indices at different times after the animals were adminstered(ig) high, median and low BAC dose. Results and conclusion BAC had a stronganalgesic effect in three types of experiments. The effect began 30 min after ad-ministration, arrived maximum at 1 h, decreased at 2 h and disappeared at 4 h.There was a dose-effect relationship between large and little BAC dose.
