简介:AbstractDue to the increase in human population, habitat destruction, and the close interaction between humans, animals and the environment, these dynamic changes are a threat to the health of human, animal and environment. Therefore, we required intervention consisting of medical, veterinary, environment and other relevant disciplines and sectors in combination. If biological and environmental health is supposed to be optimum, cooperation and coordination is necessary between the multi-sectoral stakeholders responsible for the efforts. It not limits to a region or country on a worldwide scope. One Health encourages a collaborative, coordinated, and multidisciplinary approach to ensure the health and wellbeing of humans, animals, and the environment across different spatial levels, it aims to optimal health for lives and the environment, and recognizing the interconnection between people, animals, plants, and their shared environment. This review discussed the essential to integrate One Health in the areas of infectious diseases, food safety, antimicrobial resistance, ecological environment, and chronic diseases etc., and discuss the practice of One Health in each area with some examples, hoping that One Health will serve as a framework to solve the challenges and issues facing China.
简介:追溯历史,1890年,WilliamStewartHalsted成为约翰-霍普金斯医院的第一任外科主任,并创建了外科住院医师培训体系,改写了外科教育历史。此前,美国并无正式的临床医生培训体系,有志于外科的医科毕业生或自学,或拜师学艺。Halsted提出的“Seeone,Doone,Teachone”模式[1]的目的,是使住院医师在训练中逐步增加业务难度,锻炼能力,积累经验,最终独当一面。Halsted创建该系统时,不仅着眼于外科医生的训练,亦关注于他们日后成为老师的培训。一个正规的培训体系,是确保先进外科技术传承与传播的唯一方法。
