人工智能在病理学教学中的应用

病理学属于基础医学学科,它着重研究疾病的起因、形态结构改变以及由这些变化引起的机体功能改变,为临床诊断提供依据,是基础医学与临床医学之间的重要纽带和过渡,其教学质量对后续临床实践起到举足轻重的作用,病理学教学也从传统的教学模式发展出混合式教学、虚拟病理实验室、互联网+等多种教学模式。近年来随着人工智能在医疗医学行业的飞速发展,其技术已广泛应用到医疗领域的各个方面,培养适应智能化医疗时代的新型病理人才刻不容缓。文章研究从病理学科教学工作的特点和性质入手,结合我国病理学人工智能应用现状,分析了中国目前病理专业技能培养的现状,为人工智能在病理人才专业技能与素质培养的应用中提供启发。     

失衡与治理:学术期刊数字出版产业链利益分配问题研究

【目的】 探讨学术期刊数字出版产业链中的市场主体利益分配失衡问题的解决方案,以满足各方的合理利益诉求。【方法】 运用文献法、个案研究法等,对我国学术期刊数字出版产业链上、中、下游市场主体之间利益分配失衡的现状及原因进行分析。【结果】 数据库平台企业的双边市场地位与商业模式、学术期刊数字出版产品特性与收费模式、主管部门监管不到位、行政力量推动下的非完全市场化运行机制、版权维护动力不足,以及尊重知识产权意愿不强是当前学术期刊数字出版产业链利益分配失衡的主要原因。【结论】 充分发挥主管单位与行业协会监管职能、对数据库平台企业进行改革、引入区块链技术、构建基于版权保护的利益分配机制等是平衡各方利益的有效对策。

A trivalent vaccine candidate against hepatitis E virus,norovirus, and astrovirus

Hepatitis E virus (HEV), norovirus (NoV), and astrovirus (AstV) are enterically-transmitted viral pathogens causing epidemic or endemic hepatitis (HEV) and gastroenteritis (NoV and AstV) respectively in humans, leading to significant morbidity and mortality worldwide. While a recombinant subunit vaccine against HEVs is available in China, there is no commercial vaccine or antiviral against NoV or AstV. We report here our development of a trivalent vaccine against the three viral pathogens through our new polymer vaccine technology. All HEV, NoV, and AstV are non-enveloped RNA viruses covered by a protein capsid, featuring surface protruding (P) proteins that are responsible for virus–host interaction. These dimeric P proteins elicit neutralizing antibody and are good targets for subunit vaccine development. The trivalent subunit vaccine was developed by fusion of the dimeric P domains of the three viruses together that formed tetramers. This trivalent vaccine elicited significantly higher antibody responses in mice against all three P domains than those induced by a mixture of the three free P domains (mixed vaccine). Furthermore, the post-immune antisera of the trivalent vaccine showed significantly higher neutralizing titers against HEV infection in cell culture and higher blocking activity against NoV binding to HBGA ligands than those of the post-immune sera of the mixed vaccine. Thus, the trivalent vaccine is a promising vaccine candidate against HEV, NoV, and AstV.

Public Awareness and Mask Usage during the COVID-19 Epidemic: A Survey by China CDC New Media

An online survey conducted March 18–19, 2020 on the official China CDC WeChat account platform was used to evaluate the effect of public education about masks usage during the new coronavirus disease 2019 (COVID-19) epidemic. Chinese nationals older than 18 were eligible for the survey. The survey collected 5,761 questionnaires from the 31 provinces, municipalities, and autonomous regions of mainland China. 99.7% and 97.2% of the respondents answered correctly that respiratory droplets and direct contact were the main transmission routes. 73.3% of the respondents considered COVID-19 to be ‘serious’ or ‘very serious’. When going to the hospital, 96.9% (2,885/2,976 had gone to a hospital) used a mask during the COVID-19 epidemic, while 41.1% (2,367/5,761) did not use a mask before the epidemic. Among the respondents that used public transportation and went shopping, 99.6% and 99.4%, respectively, wore masks. Among respondents who returned to work, 75.5% wore a mask at the workplace, while 86.3% of those who have not returned to work will choose to use masks when they return to the workplace. The Chinese public is highly likely to use a mask during COVID-19 epidemic, and the mask usage changed greatly since the COVID-19 outbreak. Therefore, public education has played an important role during the COVID-19 epidemic.
