China has the world’s largest burden of hepatitis B virus (HBV) infection,but the country has made considerable progress in preventing its mother-to-child transmission (MTCT) in the past three decades.This feat is made possible due to the high coverage of birth-dose hepatitis B vaccine (HepB,> 95%),hepatitis B surface antigen (HBsAg) screening for pregnant women (> 99%),and hepatitis B immunoglobulin plus HepB for newbs whose mothers are HBsAg positive (> 99%).Studies on the optimal antiviral treatment regimen for pregnant women with high HBV-DNA load have also been conducted.However,China still faces challenges in eliminating MTCT of HBV.The overall HBsAg prevalence among pregnant women is considered an intermediate endemic.The prevalence of HBsAg among pregnant women from remote,rural,or ethnic minority areas is higher than that of the national level because of limited health resources and public health education for HBV.The coverage for matal and child healthcare and immunization services should be improved,especially in west regions.Integration of current services to prevent MTCT of HBV with other relevant health services can increase the acceptability,efficiency,and coverage of these services,particularly in remote areas and ethnic minority areas.By doing so,progress toward key milestones and targets to eliminate hepatitis B as the main public health threat by 2030 can be achieved.

天然彩色棉是纤维本身带有颜色的棉花的总称。彩色棉由于在纤维发育过程中经历色素的积累和显色,可省去纤维化学染色的工艺程序,不但可以节约生产成本,而且可以减少染色过程中某些有毒化学物质的应用,降低环境污染的风险。因此,彩色棉在纺织业中具有良好的应用前景。然而,彩色棉在农业生产中并不十分受欢迎:一方面,天然彩色棉的产量偏低和品质偏差;另一方面,天然彩色棉的色彩单一;这些问题极大地限制了彩色棉的发展。杂种

纹枯病是水稻三大病害之一,从发现纹枯病至今,没有找到对纹枯病免疫的水稻种质。寻找抗源并阐明其抗纹枯病机制是当今水稻抗纹枯病遗传研究的重点。深水稻品种在长期的演化过程中积累了大量的抗湿热的特殊遗传物质,可能蕴含抗纹枯病优良种质资源。本实验利用抗旱材料沪旱1B与抗纹枯病的广西深水稻品种RSB03构建了重组自交系群体,共140个株系。以牙签嵌入法对群体进行了纹枯病抗性鉴定,对水稻抗纹枯病的分子遗传基础进
