目的　了解上海市郊青少年性与生殖健康知识、态度和行为。方法　对上海青浦区 3个镇的 80 6名 15～ 18岁青少年进行结构式问卷调查。结果　被调查的青少年己具备一定的青春期性知识 ,但对生殖系统和功能方面缺乏系统性的认识 ,一些概念含糊不清。男性的知识好于女性。中专、职校、技校学生的知识得分低于其他学校和非学生。大多数被调查者对青少年中发生恋爱和性行为持理解和宽容的态度。当地青少年中已有性行为发生 ,虽然几乎半数人知道性行为可能导致的后果 ,但首次性行为的避孕使用率却很低。他们的性知识主要来源于学校、医学书刊/杂志和同学。大多数被调查对象认为青春期性教育是必需的但学校性教育仅满足了青少年对性知识的部分需求。结论　充分了解目前青少年的性知识、性态度和性行为对设计良好的干预项目极有帮助。

Accelerating snail vector genomics

贫困所致传染病(英文) 2024年第3期13卷 6-10页

作者： Pennance tom Rollinson David College of Osteopathic Medicine of the Pacific – Northwest Western University of Health Sciences Lebanon OR USA Global Schistosomiasis Alliance Ealing Cross Uxbridge Road Ealing London W5BW UK Science Department Natural History Museum Cromwell Road London SW5BD UK

The three most important genera of snails for the transmission of schistosomes areBulinus,Biomphalaria andOncomelania. Each of these genera, found in two distantly related families, includes species that act as the intermediate host for one of the three most widespread schistosome species infecting humans,Schistosoma haematobium, S. mansoni andS. japonicum, respectively. An important step in the fight against schistosomiasis in Asia has been taken with the publication of the article "Chromosome-level genome assembly ofOncomelania hupensis: the intermediate snail host ofSchistosoma japonicum", which means that genomes for all three major genera, including species across three continents, are now available in the public domain. This includes the first genomes of African snail vectors, namelyBiomphalaria sudanica,Bi. pfeifferi andBulinus truncatus, as well as high-quality chromosome level assemblies for South AmericanBi. glabrata. Most importantly, the wealth of new genomic and transcriptomic data is helping to establish the specific molecular mechanisms that underly compatibility between snails and their schistosomes, which although diverse and complex, may help to identify potential targets dictating host parasite interactions that can be utilised in future transmission control strategies. This new work onOncomelania hupensis and indeed studies on other snail vectors, which provide deep insights into the genome, will stimulate research that may well lead to new and much needed control interventions.
