Liver biopsy plays an important role in the diagnosis of autoimmune liver diseases,particularly in patients without specific clinical manifestations or negative for autoantibodies.The histological features of several autoimmune liver diseases are reviewed.The characteristic features of autoimmune hepatitis in histology include interface hepatitis with lymphoplasmacytic infiltration,hepatic rosette formation,and emperipolesis,while chronic nonsuppurative destructive cholangitis and epithelioid granuloma are frequently found in primary biliary cirrho-sis.Primary sclerosing cholangitis is characterized by onion skin-like periductal fibrosis,while storiform fibrosis with IgG4-positive plas-ma cell infiltration often indicates IgG4 -related sclerosing cholangitis.Enhanced communication between clinicians and pathologists can help improve the diagnosis and treatment of autoimmune liver diseoses.

Objective To develop a new severe but sublethal acute pancreatitis mice model. Methods The animals were divided into two groups: the bile acid injection group and the control group. In the bile acid injection group, acute necrotizing pancreatitis was induced by intraductal administration of 0.1 ml of 1.0 % bile acid under 30 cm H 2O pressure, while the controls underwent the sham operation. The structural and functional features of the pancreas were examined at 24 hours after surgery. Results Pancreatic edema, bleeding, acinar cell necrosis and inflammation accompanied with increased serum amylase and MPO were found in the bile acid injection animals. Conclusions The sublethal acute pancreatitis mice model is ideal for pathogenetic and therapeutic study of acute necrotizing pancreatitis.

Objective To summarize the clinical histopatholngical characteristics of extranodal na-sal-type natural killer cell / T cell lymphoma. Methods 21 cases of nasal-type extranodal natural killer cell / T cell lymphoma were studied by retrospective analysis on its connection with their clinical manifesta-tions and histopathological features. Immunohietochemical SP method was used to detect the expression of immunophenotype, virus( EBV), and etc, in 21 cases. Results Capillaries had varied degrees hyperplasi-a in all cases under the microscope. Tumor cells showed definite devastating infiltration around the blood vessels, its infiltrating representation was found below intima and among vessel wall, and multiple mixed in-flammatory cells were found in it as well. Squamous epithelial pseudotumor-like proliferating can be seen in 1 case. All tumor cells'immnnophenotype were T-cell differentiation antigen CD45RO( + ), T-cell related antigen CD56 (+), T-cell particle-associated antigen TIA-1 (+), EBV (+). Conclusion Nasal-type extranodal natural killer cell / T cell lymphoma has characteristic clinical expression and histopathological changes. Accurate diagnosis can be obtained on the basis of its typical clinical expression, pathomorphology changes, immunophenotype and EBV( + ) in situ hybridization.

Purpose To investigate the expression of the protein of Ezrin and AQP5 in the normal, dysplasia gastric and carcinoma of esophagogastirc junction tissues and to find out their relationship with the biologic behavior of the carcinoma of esophagogastirc junction in the southern area of Hebei Province. Methods Ezrin and AQP5 proteins were detected by immunohistochemical staining in 10 ca-ses of normal gastric tissue, 40 cases dysplasia and 165 cases of the carcinoma of esophagogastirc junction tissues, respectively. Re-sults All of the expression levels of Ezrin and AQP5 protein were increasing according to the order of normal-dysplsia-carcinoma. The expression rate of Ezrin was 10%, 45% and 72. 7%, while the rate of AQP5 with 20%, 32. 5% and 65. 5% in the normal, dysplasia and carcinoma subgroup. The expression rates of each protein were significantly different among the three groups (P<0. 05). The ex-pression of them in the subgroup of poorly-differentiated with serosa invasion and lymph nodes metastasis was significantly higher than the other subgroup of well-differentiated with non serosa invasion or lymph nodes metastasis (P<0. 05). There was a positive correla-tion between the expression of Ezrin and AQP5 proteins in the carcinoma of esophagogastirc junction (P<0. 05). Conclusions Over-expression of Ezrin and AQP5 is detected in the carcinoma of esophagogastirc junction, with positive relationships, which probably helps the invasiveness and metastasis in the carcinoma of esophagogastirc junction synergistically.

OBJECTIVETo explore the effect of 3-n-butylphthalide pretreatment on the delayed neuronal death(DND) and the expreesion of heat shock protein70 (HSP70) in rat hippocampus after ischemia/ reperfusion.

METHODSAll rats were randomly divided into sham group (n = 36), total cerebral ischemia (TCI) group (n = 36), butylphthalide (NBP) group (n = 6), NBP + TCI group( n = 36), quercetin + NBP + TCI group (n = 6), dimethyl sulfoxide (DMSO) + NBP + TCI group (n = 6). The model of total cerebral ischemia/reperfusion was established by blocking vertebral arteries and carotid arteries. In sham group, TCI group and NBP group, the animals were further divided into instantly, 6 h, 12 h, 1 d, 3 d, 5 d groups according to the time interval after sham operation or TCI. Histological changes of the hippocampus were evaluated using thionin staining under light microscope by determining the delayed neuronal death (DND) and the expression of HSP70 was assayed using immunohistochemistry.

RESULTSNBP pretreatment could reduce delayed neuronal death in CA1 of hippocampus induced by TCI-reperfusion injury in rats, and up-regulated the expression of HSP70 in CA1 hippocampus of brain ischemic/reperfusion for 5 days. Quercetin blocked the acquirement of the brain ischemic tolerance induced by NBP preconditioning.

CONCLUSION3-n-butylphthalide (NBP) prevents the neurons from ischemia/reperfusion injury through upregulating the expression of HSP70.
