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.

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.

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

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

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.

Objective To investigate the effect of ganoderic acid A( GA-A) on apoptosis, invasion and KDR expression of human U251 cells.Methods Ganoderic acid A( GA-A) was prepared, human U251 cells were treated with 0.1, and 0.5 mmol/L GA-A, and the experiment was divided into blank control, low concentration and high concentration group.The expressions of KDR mRNA and KDR protein was assayed by RT-PCR and Western blot.The effect of GA-A on the proliferation and invasion capability of U251 cells was determined by CCK-8 and transwell assay in vitro, respectively.Flow cytometry was used to detect the influence of GA-A on the cell cycle and apoptosis of U251 cells, and TUNEL staining was detected the cell apoptosis too.Results Compared with the control group, KDR mRNA and protein expression of high concentration and low concentration group were significantly decreased(P <0.05), GA-A can significantly reduce the cell growth rate, reduce the proportion of cells in G1 phase and increase the proportion of S phase and G2 /M phase,cells apoptosis was significantly increased in the high concentration and low concentration group ( P <0.01), and cells proliferation and invasion was significantly decreased (P <0.05).Compared with low concentration group, the high concentration group induce cell apoptosis and inhibit the expression of KDR more significant (P <0.05). Conclusions Ganoderma acid A can induce apoptosis in U251 cells, inhibit proliferation and invasion, and can inhibit the expression of KDR mRNA and protein, which may be one of the mechanisms of anti-tumor.

Objective To evaluate the effect of isoflurane post-conditioningon the expression of pro apoptotic proteins in the conical neurons exposed to oxygen-glucose deprivation and restoration (OGD/R) in rats.Methods Primary cortical neurons isolated from male Sprague-Dawley rats (within 24h after birth),were cultured in vitro and inoculated in 6-well culture plate (2 ml/well) at a density of 1 × 106/ml.The cells were divided into 3 groups (n =12 each) using a random number table:control group(group C),OGD/R group,and isoflurane post-conditioning group (Ⅰ group).In OGD/R group,the cells were incubated in glucose-free BBS aerated with 95 ％ N2 for 30 min followed by restoration of 2-glucose supply for 1 h.At 24 h of incubation,the cells were collected for detection of neuronal apoptosis (.using Hoechst/PI staining),caspase-3 expression (by Western blot),expression of Bid,Bim and Puma mRNA (by PCR),and expression of Bid,Bim and Puma (by Western blot).Apoptosis rate was calculated.Results Compared with S group,the apoptosis rate was significantly increased,and the expression of caspase-3 and Bid,Bim and Puma mRNA and protein was upregulated in OGD/R group.The apoptosis rate and expression of caspase-3 and Bid,Bim and Puma mRNA and protein were significantly lower in Ⅰ group than in OGD/R group.Conclusion Isofluranepost-conditioning inhibits apoptosis in the cortical neurons exposed to OGD/R through down-regulating pm-apoptotic proteins in rats.
