BACKGROUND The association between hepatitis B virus (HBV) mutations and hepatocarcinogenesis remains controversial because of conflicting data in the literature. We conducted a meta-analysis of case-control and cohort studies to examine HBV PreS, enhancer II (EnhII), basal core promoter (BCP), and precore mutations in relation to the risk of hepatocellular(More)
Genetic predisposition of nuclear factor-kappa B (NF-kappaB)-signaling pathways linking inflammation to hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC) remains unresolved. We conducted a case-control study to determine the associations of the polymorphisms within the promoter regions of NFKB1 encoding NF-kappaB1 and NFKBIA encoding(More)
The role of genotype mixture and subgenotypes remains controversial in determining the clinical outcome of chronic hepatitis B virus (HBV) infection. We aimed to determine their role on the development and the recurrence of hepatocellular carcinoma (HCC). HBV genotypes, serum viral load and hepatitis B e antigen (HBeAg) seroconversion were determined in 462(More)

INTRODUCTION Hepatitis B virus (HBV) genotypes, replication status, and mutations have been associated with the risk of hepatocellular carcinoma (HCC). Our aim was to study the distribution and HCC-related viral properties of HBV genotypes/subgenotypes in Mainland China. METHODS A multistage cluster probability sampling method was applied to select 81,775(More)
Background.  Human infections with avian influenza A(H7N9) virus have been associated with exposure to poultry and live poultry markets (LPMs). We conducted a case-control study to identify additional and more specific risk factors. Methods.  Cases were laboratory-confirmed A(H7N9) infections in persons in China reported from October 1, 2014 to April 30,(More)
