AIM To determine the antiviral mechanism or target of oxymatrine against hepatitis B virus (HBV). METHODS HepG2.2.15 cells were incubated with culture medium containing 500 microg/mL of oxymatrine for 2 and 5 d. The surface antigen of HBV (HBsAg) and e antigen of HBV (HBeAg) in supernatant were determined by ELISA. HBV DNA in supernatant, and(More)
INTRODUCTION Accurate clinical staging of mediastinal lymph nodes (MLNs) of patients with non-small cell lung cancer (NSCLC) is important in determining therapeutic options and prognoses. Integrated positron emission tomography and computed tomography (PET/CT) scanning is becoming widely used for MLN staging in patients with NSCLC. We performed a bivariate(More)
Baicalein, a naturally occurring flavone, has been proved as a promising chemopreventive compound for many chronic human diseases. The aim of this work was to investigate whether treatment with baicalein prevented nonalcoholic steatohepatitis (NASH) induced by methionine-choline-deficient (MCD) diet. Rats were divided into four experimental groups and fed(More)
INTRODUCTION Lung cancer is the leading cause of cancer-associated death. In many countries, adenocarcinoma is the most common histologic type in lung cancer. Previously, few factors are identified to be prognostic indicators for the patients with small lung adenocarcinoma. Recently, the ground glass opacity (GGO) area found on high-resolution computed(More)
BACKGROUND Nosocomial infections are a major threat to patients in the intensive care unit (ICU). Limited data exist on the epidemiology of ICU-acquired infections in China. This retrospective study was carried out to determine the current status of nosocomial infection in China. METHODS A retrospective review of nosocomial infections in the ICU of a(More)
The objective of this study is to investigate the characteristics of the recombinant variant of human vascular endothelial cell growth inhibitor, VEGI72-251, and compare its biological activities with that of its prototype VEGI24-174. The recombinant plasmid containing the variant VEGI72-251 gene was constructed and expressed in Escherichia coli. The(More)
BACKGROUND Can single-agent maintenance therapy be considered as an ideal strategy for non-small cell lung cancer (NSCLC) treatment to achieve prolonged survival and tolerated toxicity? A systematic review and meta-analysis was performed to elucidate this issue. METHODS The electronic databases were searched for RCTs comparing single-agent maintenance(More)
OBJECTIVE To study the effect of HBV on human hepatic cytochrome P450 3A4 (CYP3A4) in patients with chronic HBV infection. METHODS Liver tissue samples were obtained from 21 patients undergoing hepatic surgery with (n = 10) or without (n = 11) chronic HBV infection and were homogenized, then hepatic microsomes were separated from the homogenate using a(More)
OBJECTIVE To investigate the spontaneous YMDD mutation rate. METHODS Serum samples collected from 196 untreated chronic HBV patients were detected by primer-specific real-time PCR. RESULTS Among 196 patients, spontaneous YMDD variants were detected in 21 subjects (20 YVDD mutants and 1 YIDD mutant). YMDD variants account for more than 50%, 25% to 50%,(More)
BACKGROUND Hepatitis B virus encoded X protein (HBx) is a trans-activating protein that may be involved in hepatocarcinogenesis, although few natural effectors of HBx that participate in this process have been identified. We screened, by comparative proteomics method, effectors of HBx associated with hepatocarcinogenesis. METHODS HBx positive and negative(More)
