Objective To compare the differences of clinical characteristics between genotype B and C chronic hepatitis B(CHB)patients and to summarize clinical factors related to genotype C hepa- titis B virus(HBV)infection.Methods Seventy eight CHB patients who were diagnosed with genotype B or C infection by liver puncture biopsy and genotyping were enrolled.Their serum HBV DNA levels were detected.Severe hepatitis,liver cirrhosis,hepatocellular carcinoma and HBeAg positive rate were analyzed to determine the pathologic inflammation and fibrosis degree of liver tissue.Chi square test and Logistic multiple regression analysis were employed for the statistical analysis.Results The serum albumin and pre-protein were lower in genotype C CHB patients than that in genotype B.The alanine aminotrans- ferase,total bilirubin and prothrombin time were higher in genotype C CHB patients than that in genotype B.The rates of genotype C patients increased significantly with the grade of liver necroin- flammation progressing from GO to G4(1.8%,11.1%,20.4%,33.3%,33.3%) and the stage of liver fibrosis progressing from SO to S4(5.6%,5.6%,14.8%,33.3%,40.7%),but the rates of genotype B patients did not change significantly with the grade of liver necroinflammation(16.7%, 25.0%,25.0%,20.8%,12.5%)and stage of liver fibrosis progressing(16.7%,29.2%%,20.8%, 16.7%,16.7%).There was statistical significance in grades of liver necroinflammation(X~2= 11.49,P=0.022)and stages of liver fibrosis(X~2=13.56,P=0.006)between genotype B and gen- otype C patients.The rates of genotype C CHB patients were higher than,similar with and lower than the rates of genotype B patients of HBV DNA level above 1.0?10~6 copy/mL,between 5.0?10~2-1.0?10~6 copy/mL and under 5.0?10~2 copy/mL,respectively(51.8% vs 12.5%,35.2% vs 45.8% and 13.0% vs 41.7%).There was statistical significance of HBV loads between genotype B and genotype C patients(X~2=13.25,P=0.001).HBeAg positive rate in genotype C patients was significantly higher than that in genotype B patients(61.1% vs 25.0%,X~2=8.67,P=0.003).The rates of decompensated cirrhosis,compensated cirrhosis and no-cirrhosis in genotype C patients were higher than,similiar with and lower than the rates in genotype B patients,respectively(40.7% vs 4.2%,22.2% vs 20.8% and 37.0% vs 75.0%).There was statistical significance of the rate of cirrhosis between genotype B and genotype C patients (X~2=12.47,P=0.002).Conclusions The degree of liver necroinflammation and fibrosis,the HBeAg positive rate and the incidence of cirrhosis are all related with genotype C HBV infection.

Objective To investigate the mechanism of Bushentongluoshugan Formula's effect in penile erection.Method All 40 adult male rats were randomly divided into the control group, castrated group, Bushentongluoshugan Formula group and sterandryl group.The rats of all groups, except the control group, were ablated bilateral testes. Bushentongluoshugan Formula group and sterandryl group were given the formula and sterandryl respectively. After 3 weeks the penile tissue was collected and the expression of transforming growth factor-β-mRNA (TGF-β-mRNA) was detected by using polymerase chain reaction (PCR) technique.Result The expression of TGF-β-mRNA in the castrated group was higher than that in other three groups, and among them the incremental order was the control group, sterandryl group and Bushentongluoshugan Formula group according to the decreasing performance of TGF-β-mRNA expression. The internal control of TGF-β-mRNA was less in the control group, sterandryl group and Bushentongluoshugan Formula group with a significant difference compared with that in the castrated group (P<0.01), and there was no significant difference between the sterandryl group and Bushentongluoshugan Formula group (P>0.05).Conclusion Bushentongluoshugan Formula plays an important role in penile erection through regulating the expression of TGF-β-mRNA.

OBJECTIVETo investigate the association of SOX9 expression and clinicopathologic factors and prognosis of gastric cancer.

METHODSA retrospective cohort study including 112 gastric cancer patients admitted to the Zhejiang Provincial People's Hospital from 2004 to 2006 was performed. Immunohistochemical analysis was used to evaluate the expression of SOX9 in the 112 specimens of gastric cancer tissues and 70 non-cancerous tissues adjacent to the tumor.

RESULTSLow expression of SOX9 was seen in 5(7.1%) tissues out of 70 non-cancerous tissues adjacent to the tumor. A total of 94(83.9%) patients had varying expression of SOX9, of whom 51(45.4%) had overexpression. Univariate analysis demonstrated that the expression of SOX9 was significantly associated with Lauren classification (P<0.05), tumor invasion(P<0.01), lymph node metastasis(P<0.05), distant metastasis(P<0.05) and tumor stage(P<0.05), however there was no significant association between SOX9 expression and sex, age, histological type, histology differentiation or tumor size. Kaplan-Meier analysis showed that the 5-year survival rate of patients with SOX9 over-expression was significantly lower than that of patients with low expression(29.4% vs. 49.2%, P=0.031). Multivariate Cox regression analysis showed that histology differentiation(P=0.046), tumor invasion(P=0.001), and distant metastasis(P<0.01) were independent prognostic factors for gastric cancer, however the over-expression of SOX9 was not significant(P=0.948).

CONCLUSIONSThe expression SOX9 is associated with the growth, invasion, and metastasis of gastric cancer, as well as the prognosis. However, SOX9 expression is not an independent factor for the prognosis in patients with gastric cancer.

BACKGROUNDAlthough clinical treatment for heart failure and sudden death has been improved over the last few decades, the morbidity and mortality of dilated cardiomyopathy (DCM) have increased. So a better understanding of the underlying molecular events leading to DCM is urgent. Persistent viral infection (especially coxsackievirus group B3) of the myocardium in viral myocarditis and DCM has never been neglected by experts. Recent data indicate that the up-regulation of coxsackievirus and adenovirus receptor (CAR) in viral cardiomyopathy contributes to viral infection as a key factor in the pathogenesis of this disease. This study aimed to investigate the role and regulatory mechanism of CAR in DCM by the bioinformatic method.

METHODSWe identified the clusters of genes co-expressed with CAR by clustering algorithm based on the public available microarray dataset of DCM (Kittleson, et al. 2005), and mapped these genes into the protein-protein interaction networks to investigate the interaction relationship to each other at the protein level after confirming that the samples are characterized by the cluster of genes in correctly partitioning.

RESULTSThe gene cluster GENESET 11 containing 33 genes including CAR with similar expression pattern was identified by cluster algorithm, of which 19 genes were found to have interaction information of the protein encoded by them in the current human protein interaction database. Especially, 12 genes present as critical nodes (called HUB node) at the protein level are involved in energy metabolism, signal transduction, viral infection, immuno-response, cell apoptosis, cell proliferation, tissue repair, etc.

CONCLUSIONSThe genes in GENESET 11 together with CAR may play a pathogenic role in the development of DCM, mainly involved in the mechanism of energy metabolism, signal transduction, viral infection, immuno-response, cell apoptosis and tissue repair.
