First, the significance of learning medical ethics L. It is conducive to establishing lofty medical ethics. Moral construction is an important content of socialist spiritual civilization construction. As a professional ethics, medical ethics is an important part of the whole socialist moral system. Doing a good job in medical ethics education, improving the moral level of medical and health units, medical staff and managers, has made contributions to the construction of socialist spiritual civilization. Because medical and health work is related to all members of society and has a wide range of sociality, it is one of the important ties between the party and the state and the people, and it is a "window" industry characterized by service. Therefore, the medical ethics level of medical and health departments, medical staff and managers is an important symbol to measure the degree of spiritual civilization. In real life, some medical and health units, despite poor medical equipment, have good medical ethics, medical staff and management personnel, and serve the people's physical and mental health wholeheartedly in medical practice, so they are welcomed and praised by patients and society. On the contrary, some units have good medical equipment, but poor medical ethics, which sometimes leads to mistakes and accidents, medical disputes, criticism and condemnation by public opinion, and even damage to their reputation. Therefore, noble medical ethics plays a positive role in improving social morality and protecting socialist productive forces. This requires medical and health units, medical staff and managers to seriously strengthen the construction of medical ethics, treat and handle every patient with noble medical ethics, which can not only comfort patients and their families mentally, but also feel the superiority and warmth of socialism, and be influenced by socialist spiritual civilization, resulting in good social effects. Give full play to its role as a "window of civilization" of socialism. 2. It is conducive to cultivating medical talents with both ability and political integrity. The purpose of socialist medical education is to cultivate new medical talents with both ability and political integrity and serve the socialist construction. The so-called new medical talents with both ability and political integrity refer to those who consciously adhere to the Four Cardinal Principles and have noble medical ethics, and those who learn and master modern medical knowledge and skills. Therefore, learning medical ethics and strengthening medical ethics education are important links to achieve this goal. For medical students, what they learn today is directly related to what they do tomorrow. Throughout the history of medical ethics, Sun Simiao, a famous doctor in the Tang Dynasty, can be described as a master of ancient medical ethics in China. He pointed out that a "great doctor" must be "sincere". "Essence" and "sincerity" must be unified and complement each other. Ancient doctors still do, not to mention modern doctors. Deng Xiaoping asked medical workers to become Bethune-style revolutionaries and scientists. It can be seen that learning medical ethics is of great significance to cultivate and improve the quality and knowledge structure of medical talents. Because medical students and medical workers can learn medical ethics, master relevant medical ethics knowledge and norms, and attach importance to strengthening medical ethics cultivation ideologically, they will be competent after graduation. If we only pay attention to the study of professional knowledge and technology and ignore medical ethics, then no matter how high the medical skill is, it will lose its value. At the same time, we should also see that medical students are the reserve force of China's health cause. Strengthening medical ethics education is not only related to the personal growth of medical students, but also to the future moral trend and the prosperity of the whole health cause in China. To study and study medical ethics, we must adhere to the following scientific methods: 1. Adhere to dialectical materialism and historical materialism. People's social and material relations are the basis of moral production and existence. Only by explaining moral problems from people's social relations can we draw scientific conclusions. Medical ethics is based on medical moral phenomena in the medical field. This medical ethical phenomenon is not only determined by a certain social and economic foundation, but also influenced by social politics, philosophy, law and other concepts, and it is also a direct product of medical practice. Therefore, to investigate the phenomenon of medical ethics, only from a certain social and historical conditions, a comprehensive, historical and specific analysis can we get a scientific answer. Under the socialist conditions, the study and research of medical ethics must proceed from the socialist economic relations and adhere to the guidance of Marxism, Mao Zedong Thought and Deng Xiaoping Theory. Only in this way can we understand the essence and development law of socialist medical ethics. 2. Adhere to the method of critical inheritance and absorption. Medical ethics is closely related to the medical practice of medical staff and comes from the common requirements of the medical industry. Therefore, it has strong stability and continuity in content. Let some noble medical ethics be carried forward on the basis of inheritance and absorption. The medical ethics heritage of the motherland is very rich, and many doctors' medical ethics thoughts and excellent examples are still dazzling. Many doctors regard saving lives and protecting patients' lives as lofty medical ethics creed. It advocates treating patients equally, regardless of grades, not being tempted by debauchery, not being shaken by money, not giving in to power, and showing noble moral sentiments. These positive aspects are worth inheriting and developing. However, the medical ethics of the motherland are also negatively influenced by feudal relations of production, feudal morality and religious superstition. At the same time, foreign medical ethics not only has a long history, but also has made many new achievements with the development of science and culture. For example, some medical scientists are persistent in science, and some medical ethics explorations in the fields of artificial insemination and IVF are worth learning. However, due to the differences in social system, scientific culture and religious belief, foreign medical ethics has its limitations and negative aspects. Therefore, when studying medical ethics, we must adhere to the method of critical inheritance. Starting from the needs of socialist medical practice and the health interests of the broad masses of the people, we should comprehensively clean up and test the historical heritage and modern achievements of Chinese and foreign medical ethics by using Marxist standpoints, viewpoints and methods, take the essence, discard the dross, process and transform them, and absorb all beneficial and positive components and factors into the socialist medical ethics system to jointly build a new medical ethics system with China characteristics. Adhering to the method of integrating theory with practice is the most basic method of Marxism and also the basic method of studying ethics. We should always adhere to the integration of theory and practice, knowing and doing. First of all, we should seriously study the basic theory of Marxist ethics, understand the origin, essence, function and development law of medical ethics, and further explore the new problems reflected by medical ethics consciousness, medical ethics phenomenon, medical ethics behavior and medical ethics relationship in the primary stage of socialism. Second, practice. The purpose of learning medical ethics is to practice internal strength and achieve the unity of knowledge and practice. On the one hand, we should proceed from reality and pay attention to observing and investigating various ethical issues in medical practice. We can conduct practical and targeted research on various ethical issues through field visits, interviews, discussions and typical case analysis, so as to find out the laws. On the other hand, we should use socialist medical ethics principles and norms to guide our actions, consciously strengthen medical ethics cultivation in medical practice, constantly exercise and cultivate our own medical ethics feelings, will and beliefs, and serve the people's physical and mental health wholeheartedly.
