野生动物学报, 2020 的：为了解黑龙江省和吉林省健康貉中大肠杆菌四环素耐药基因的分布情况，以貉源大肠杆菌为模板，检测四环素耐药基因，为控制耐药性奠定基础，有利于临床合理用药。方法：共选取56株貉大肠杆菌，通过PCR扩增靶基因以检测耐药基因的携带状态。 结果：四环素抗性基因tetM的检出率为82.14%，还检测到tetA、tetB、tetC、tetD，未检测出tetE。结论：大肠杆菌四环素耐药性可能由几种耐药基因共同介导。试验结果可为貉临床实践中合理使用四环素和预防四环素抗性出现提供理论依据。

Application of artificial intelligence in educational measurement: opportunities and ethical challenges [PDF]
人工智能（Artificial Intelligence, AI）与教育测量的结合促进了测评方法的转变，通过机器学习和自然语言处理，实现了自动评分、快速内容分析和个性化反馈。这些发展为学生的表现提供了宝贵的见解，同时也提升了整体测评体验。然而，AI在教育领域的应用也引发了有关效度、信度、透明性、公平性和公正性的重大伦理问题。算法偏差和AI决策过程不透明等问题有可能加剧不平等，影响测评结果。为此，包括教育工作者、政策制定者和测试机构在内的各利益相关方制定了指导方针，以确保AI在教育领域中的应用符合伦理规范。
