OBJECTIVE To determine the prevalence of hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and hepatitis B core anti-body (anti-HBc) in a representative population in China 14 years after introduction of hepatitis B vaccination of infants. METHODS National serosurvey, with participants selected by multi-stage random sampling.(More)
BACKGROUND Endemic hepatitis B virus (HBV) infection is a serious health problem in China. Hepatitis B vaccination of infants was introduced in 1992 and was progressively expanded during the subsequent 15 years. METHODS We conducted a national serosurvey, with participants selected by multiple-stage random sampling. Demographic characteristics and(More)
BACKGROUND In China, the prevalence of chronic hepatitis B infection was high because of perinatal and early childhood transmission. A three-dose hepatitis B vaccine schedule with a first dose as soon as possible after birth was introduced in 1992 and generalized in 2002 in the Expanded Programme of Immunization (EPI). In 2006, a serological survey(More)
BACKGROUND Mother to Child Transmission (MTCT) has remained a leading cause of HBV infection in China, accounting for 40% of total infections. Providing hepatitis B vaccine (HepB) to all infants within 24h of birth (Timely Birth Dose, TBD), and subsequent completion of at least 3 vaccine doses is key to preventing perinatal HBV infection. In 2002, with the(More)
Nerve sprouting in healed myocardial infarction has been associated with increased incidences of ventricular tachyarrhythmia and sudden cardiac death. However, the underlying electrophysiological mechanisms are unclear. To investigate the linkage between nerve sprouting and potassium channel function, we developed a rat model of cardiac sympathetic nerve(More)

Angiostrongylus cantonensis is an emerging zoonotic pathogen that has caused hundreds of cases of human angiostrongyliasis worldwide. The larva in nonpermissive hosts cannot develop into an adult worm and can cause eosinophilic meningitis and ocular angiostrongyliasis. The mechanism of brain inflammation caused by the worm remains poorly defined. According(More)
Hepatitis B virus (HBV) is highly endemic in Southwest China; an area with many ethnic minorities. Information about the genetic distribution of HBV is still limited. In 2010, a multistage cluster sampling method was carried out in the Southwest China. Five hundred forty serum samples of participants were collected. Polymerase chain reaction followed by(More)
The twin aims of this study were to investigate the changes in anti-HBs IgG levels after booster vaccinations and to compare the effects of different vaccine doses in children aged 11-15 years who were both negative for HBsAg and had an Anti-HBs < 10.0 mIU/mL after primary vaccination. Children who were born between 1993 and 1998 and who had completed(More)
Cardiac ventricular myocytes possess an extensive t-tubular system that facilitates the propagation of membrane potential across the cell body. It is well established that ionic currents at the restricted t-tubular space may lead to significant changes in ion concentrations, which, in turn, may affect t-tubular membrane potential. In this study, we used the(More)
