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 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.

The mobile speed was 0.9 mL/min. Separation column was Kroasil ODS(4.6 mm?250 mm). Result A good linearity was obtained in the range of 65～325 ?g,regression A=24 239 869C-31 292,r=0.999 3. The average recovery was 100.10%,RSD was 0.87%(n=6). Conclusion The method was good for determining chlorogenic acid in Jinyin Granules.

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 investigate the relation between plasma macrophage migration inhibitory factor(MIF) concentration and the activity of activator protein-1(AP-1) in peripheral blood and coronary heart disease(CHD),and their relation with coronary arteriosclerosis plaques in patients with CHD.Methods One hundred and forty two patients were divided into coronary heart disease(CHD) group(n=107) and control group(n=35) according to coronary angiographic(CAG) result.The CHD group was further divided into stable angina pectoris(SAP) group(n=33) and acute coronary syndrome(ACS) group(n=75) according to clinical manifestations.In addition,according to the type of coronary lesions,the CHD group was further divided into the type A lesion(n=30) group,type B group(n=48) and type C group(n=29).According to the degree of coronary stenosis,the CHD group was also divided into mild stenosis group(n=21),moderate stenosis group(n=31) and severe stenosis group(n=55).The amount of Phospho-c-Jun in lysate and plasma MIF concentration were measured by enzyme-linked immunosorbent assay(ELISA).The results of Phospho-c-Jun was demonstrated with absorbance.Which reflect the amount of AP-1.Results The absorbance of Phospho-c-Jun in the CHD group was higher than that in the control(1.43?0.33 vs 0.71?0.13,P

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.

Objective To evaluate the accuracy of multi-detector-row CT (MDCT) in the diagnosis and preoperative evaluation of breast cancer. Methods From January 2004 to December 2007,the clinical data of 54 cases wih pathologically proved breast cancer undergoing preoperative MDCT scan (31 cases also underwent MRI scan) were retrospectively analyzed at our hospital. Surgical planning was based on MDCT assessment. The extent and location of tumor depicted by MDCT,MRI and pathology were compared. Results Breast carcinoma was diagnosed by MDCT in all the cases. In these 54 patients,MDCT achived an accuracy of 87% in evaluating the extent of tumor. Based on MDCT,39 cases underwent BCT surgery with a 8% margin positive rate. MDCT and MRI had no significant difference in accuracy of evaluation on the extent of tumor ( x2 = 0. 5, P ＞ 0. 05 ). Conclusions MDCT accurately assesses the extent and location of breast cancer, proving its value in preoperative evaluation of breast cancer.

Objective: To study the prevalence and pathogenesis of TT virus (TTV) in hemodialysis patients. Methods: Serum TTV DNA was tested in 69 hemodialysis patients from our hospital by nested-PCR using primers from a conservative region of TTV genenome, genetic analysis and detection of hepatitis C virus antibody (anti-HCV) and the levels of alanine aminotransferase (ALT) were also carried out simultaneously. Results: The overall prevalence of TTV viremia was 27.5%. The PCR-amplified gene fragment from one patient was sequenced, and its gene sequence homologies with GH1,TA278, TTVCHN1 and TTVCHN2 ranged from 89% to 100%, its deduced amino acid sequence ranged from 87% to 100%. There was no significant difference of TTV prevalence between anti-HCV positive and negative patients. No significant elevation of ALT was found in all patients. Conclusion: High prevalence of TTV infection is found among hemodialysis patients, and TTV infection has no significant association with HCV infection or elevation of ALT.
