| 1 | Hepatitis B infection among adults in the philippines:A national seroprevalence study显示文摘AIM:To determine the prevalence of hepatitis B surface antigen(HBsAg)seropositivity among adult Filipinos.METHODS:Testing for HBsAg was performed on serum samples from persons aged ≥ 20 years old who participated in the National Nutrition and Health Survey(NNHeS)conducted in 2003.Information on age,sex,marital status,educational attainment,employment status,and income were collected.For this study,marital status was classified as never married or otherwise(i.e.,married,divorced,separated,widowed);educational attainment was classified as high school graduate or below or at least some tertiary education;and employment status was classified as currently employed or currently unemployed.Annual income was divided into 4 quartiles in Philippine pesos(PhP):Q1,≤ PhP 53064;Q2,PhP 53065-92192;Q3,PhP 92193-173387;and Q4,≥ PhP 173388.Prevalence estimates were weighted so that they represented the general population.Social and demographic factors were correlated with HBsAg seropositivity.Multivariate analysis was used to determine independent predictors of HBsAg seropositivity.RESULTS:A total of 2150 randomly selected adults,20 years and over,out of the 4753 adult participants of NNHeS were tested for HBsAg.The HBsAg seroprevalence was 16.7%(95%CI:14.3%-19.1%),which corresponded to an estimated 7278968 persons infected with hepatitis B.There was no significant difference between males and females(17.5% vs 16.0%;P = 0.555).This corresponded to an estimated 3721775 men and 3557193 women infected with hepatitis B.The HBsAg seroprevalence peaked at age 20-39 years old,with declining prevalence in the older age groups.The only independent predictor of HBsAg seropositivity was the annual income,with persons in the highest income quartile being less likely to be HBsAg positive(age-adjusted OR = 0.51;95%CI:0.30-0.86)compared to subjects in the lowest income quartile.Sex,marital status,educational attainment,and employment status were not found to be independent predictors of HBsAg seropositivity.CONCLUSION:The high HBsAg seroprevalence among adults in the Philippines classifies the country as hyperendemic for HBV infection and appears unchanged over the last few decades. | Stephen N Wong Janus P Ong Madalinee Eternity D Labio Oscar T Cabahug Maria Lourdes O Daez Erlinda V Valdellon Jose D Sollano Jr Marilyn O Arguillas | 2013 | World Journal of Hepatology2013，5，4： | 3 |
| 2 | 精液叶酸、维生素B_(12)、活性氧水平与精子质量关系研究显示文摘目的 : 检测人精液叶酸、维生素 B12 ( VB12 ) ,及活性氧 ( ROS)的含量 ,探讨三者与精子质量的关系。方法 : 收集经证实配偶已怀孕的新加坡籍健康成年男性 1 76名的精液 ,根据WHO推荐方法检测精子质量各项指标 ,并测定精液叶酸和 VB12 含量及 ROS水平。结果 : 平均精液量、精子浓度和其活力都在正常范围内。而精子存活率 ( 73.0 6% )略低于 WHO标准 (≥ 75% ) ,形态异常的精子 ( 77.0 6% )高于 WHO标准 ( 70 % )。精液的叶酸含量与 ROS水平呈显著负相关 ( r=- 0 .2 5,P=0 .0 0 3) ;VB12 与 ROS呈负相关 ( r=- 0 .2 5,P=0 .0 0 2 ) ,与精子形态异常也呈负相关( r=- 0 .1 5,P=0 .0 4 8) ,但与精子浓度呈正相关 ( r=0 .31 ,P<0 .0 0 1 )。ROS与精子形态异常呈正相关 ( r=0 .2 5,P=0 .0 0 2 ) ,与精子活力也呈正相关 ( r=0 .1 9,P=0 .0 1 9)。结论 : VB12 对精子生成和维持精子正常功能是必需的 ,ROS水平与精子功能缺陷有关 ,VB12 和叶酸可能通过降低 ROS以维持精子的正常功能。 | 陈起萱 梅节 V Ng SE Chia 凌文华 CN Ong | 2001 | 营养学报2001，23，2： | 2 |
