Down syndrome (DS) is the most common chromosomal abnormality. Many studies have assessed the association between maternal gene polymorphisms involved in folate metabolism and the risk of having a DS offspring, but data are conflicting. Our study aimed to arrive at a more accurate estimation. Therefore, we carried out a meta-analysis of 26, 17, 9, 15, 9 and(More)
OBJECTIVE To study the visual acuity and astigmatism of persons undergoing cataract extraction by local surgeons in rural China. METHODS Visual acuity, keratometry, and refraction were measured 10 to 14 months postoperatively for all cataract cases during 4 months in Sanrao, China. RESULTS Among 313 eligible subjects, 242 (77%) could be contacted, of(More)
OBJECTIVES The aim of this study was to investigate the prevalence and epidemiological characteristics of hypertension in the Chinese She ethnic minority in Fujian province of China. After analyzing relevant risk factors of hypertension, we wanted to provide information for prevention and control of hypertension in this ethnic minority. METHODS Using the(More)
BACKGROUND Despite effective immunoprophylaxis, vertical transmission of hepatitis B virus (HBV) from infected mothers still occurs. This study aimed to provide an estimate of the prevalence of immunoprophylaxis failure and evaluate associated risk factors. METHODS A hospital-based prospective study was conducted from June 1, 2008, to June 30, 2012. In(More)
OBJECTIVE Hepatitis B immune globulin (HBIG) injection during pregnancy and/or after birth is an intervention for preventing mother-to-child transmission of the hepatitis B (HB) virus. However, varying cost-effectiveness ratios among various HBIG therapies remain unclear. This study explored these differences in cost-effectiveness ratios. METHODS Four(More)
BACKGROUND Human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) are among the most complex health problems in the world. Young people are at high risk of HIV and AIDS infections and are, therefore, in need of targeted prevention. School-based HIV/AIDS health education may be an effective way to prevent the spread of AIDS among(More)
PURPOSE To model the possible impact of using average-power intraocular lenses (IOLs) and evaluate the postoperative refractive error in patients having cataract surgery in rural China. SETTING Rural Guangdong, China. METHODS Patients having cataract surgery by local surgeons were examined and visual function was assessed 10 to 14 months after surgery.(More)
Many studies have accessed the association between methionine synthase (MTR) A2756G polymorphism and neural tube defect (NTD). However, the conclusions are inconsistent. Our study aimed to clarify the nature of the genetic risks contributed by this polymorphism for NTD using meta-analysis. We searched electronic literature from the PubMed, EMBASE, and(More)
Intrauterine infection of hepatitis B virus (HBV), which accounts for the majority of mother-to-child transmission, is one of the main reasons for the failure of combined immunoprophylaxis against the transmission. Recent studies have identified that genetic background might influence the susceptibility to intrauterine infection of HBV. We conducted this(More)
GOALS To examine the impact of maternal hepatitis B virus infection on pregnancy outcomes. BACKGROUND Studies regarding hepatitis B virus infection and pregnancy outcomes are limited with inconsistent results, and none of them have evaluated the effect of maternal viral load in pregnancy on pregnancy outcomes. STUDY A hospital-based case-control study(More)
