Résumé

Objective To investigate the effects and possible mechanism of action of inhibiting hepatitis B virus X protein (HBx) expression on liver cancer metastasis. Methods The suppression of HBx expression in MHCC97H cells was performed by siRNA interference technique, and the effects of HBx suppression on the metastasis of MHCC97H cells were detected by Matrigel invasion assays and in a lung-metastasis mouse model. The expression levels of related epithelial-mesenchymal transition (EMT) and apoptosis proteins were examined by Western blotting. Results Introduction of HBx-siRNA into MHCC97H cells inhibited the expression of HBx and the ability to metastasize,downregulated the expression of Twist and N-cadherin, and upregulated E-cadherin expression. These changes resulted in inhibiting EMT of MHCC97H cells. Meanwhile, apoptosis involved in the Twist-P53 pathway was also found. Conclusions Inhibiting expression of HBx can decrease the metastatic a-bility of MHCC97H cells by changing EMT and inducing apoptosis.

Résumé

Abstract Objective:To evaluate the value of measurement of serum intercellular adhesion molecule-l(sICAM-l) and sE-selectin in di-agnosis and postoperative monitoring for hepatocellular carcinoma. Methods: sICAM-1 and sE-selectin were measured in patients with chronic hepatitis,liver cirrhosis,HCC and healthy controls by ELISA. Results:The mean levels of sICAM-1 and sE-selectin in 79 patients with HCC was significantly higher than that of other three groups ( P

Résumé

OBJECTIVE To investigate dynamics of bacteria in biliary tract infections and their sensitivity to antibiotics.METHODS All bile specimens were collected from surely patients with biliary infection by endoscopic nasobiliary drainage or surgery in Union Hospital affiliated to Fujian Medical University,from Jan 2002 to Dec 2005.All specimens were cultured,and followed by bacterial identification and antibiotics resistance assay.RESULTS The ratio of Gram-negative bacteria in all bacteria of biliary tract infections was decreased(r=-0.983,P
