The relationship between preventive medicine and chemistry lies in that preventive medicine is an industrial chemical toxicology and pollution prevention management, which makes people have a healthy living space and is a subject mainly studying chemistry. Preventive medicine is a science that takes "environment-people-health" as the model, takes people as the research object, takes prevention as the main ideological guidance, uses modern medical knowledge and methods to study the law of environmental impact on health, formulates measures to prevent human diseases, and realizes the purpose of promoting health, preventing disability and premature death. The characteristics of preventive medicine include: working objects include individuals and groups, focusing on healthy and asymptomatic patients, countermeasures and measures have more positive preventive effects and more health benefits for the population, research methods pay more attention to the combination of micro and macro, and research focuses on the relationship between environment and population health. The difference between preventive medicine and clinical medicine is that it is aimed at people, not just individuals. One of the trends of medical development is from individual medicine to group medicine. Today, it is impossible to completely solve many medical problems without group and group medical methods. The task of preventive medicine requires that it must be far-sighted, face the future of medicine and consider human diseases and health problems from a strategic perspective. Toxicology is a science that studies the damage and action mechanism of chemical substances to organisms from the perspective of biomedicine. However, in recent years, with the objective needs, the research scope of toxicology has been extended to radiation, microwave and other harmful factors, physical factors and biological factors, not just chemicals. Health toxicology is a branch of toxicology directly related to public health work, including environmental toxicology, industrial toxicology, food toxicology, pesticide toxicology and radiotoxicology. Hygienic toxicology belongs to the category of preventive medicine and is a branch of toxicology. Any chemical substance may be harmful to the body under certain conditions. The purpose of health toxicology is to study the toxicity of exogenous chemicals and the conditions that produce toxic effects, clarify the dose-effect relationship, and provide theoretical basis for formulating health standards and preventive measures. This subject applies modern medicine and other scientific and technological means to study the relationship between human health and environmental factors and formulate disease prevention strategies and measures in order to control diseases, protect human health and prolong human life. With the development of medical model, this major shows its importance in medical science more and more. This major trains doctors who are engaged in preventive medicine experiments and scientific research, and have certain knowledge of health management and foreign language level. On the basis of mastering the theoretical knowledge and skills of general clinical medicine, students can systematically master the basic theories, knowledge and skills of their major and engage in practical work and scientific research by using the knowledge and skills they have learned.
Business training objectives: this major trains senior medical talents who have basic theoretical knowledge of preventive medicine and health detection technology and can engage in preventive medicine in institutions such as health and epidemic prevention, environmental sanitation or food hygiene monitoring.
Business training requirements: Students in this major mainly study the basic theoretical knowledge of basic medicine and preventive medicine, receive basic training in health detection technology and disease control, and have the basic abilities of health and epidemic prevention, control of infectious diseases and occupational diseases, improvement of people's environmental sanitation conditions and implementation of food hygiene supervision.
