The key to chronic disease control lies in prevention of risk factors, prevention of morbidity, prevention of serious disease events, prevention of serious consequences of disease events, and prevention of relapse after disease events, so early diagnosis and treatment are crucial. Chinese medicine has systematic theoretical knowledge and rich experience in the prevention and treatment of chronic diseases, and its perfect system of theory, method, prescription and medicine has formed the advantages of prevention and treatment of chronic diseases. 1.Individualized diagnosis and treatment mode of evidence-based treatment Chinese medicine grasps the dynamic changes of diseases according to the health condition and life information of human body, uses four kinds of diagnosis methods: looking, smelling, asking and cutting, collects the external information of human body, and determines the corresponding treatment principles and methods by synthesizing, analyzing and judging the overall state of human body (symptoms). This mode of diagnosis and treatment, on the one hand, can truly realize individualized diagnosis and treatment, on the other hand, can intervene at an early stage to prevent the evolution of diseases, so as to achieve the human-oriented health care goal of balancing yin and yang and harmonizing the internal organs. 2, holistic concept and overall regulation of the means of prevention and treatment The holistic concept of Chinese medicine has three meanings: First, the human body is an organic whole. Chinese medicine believes that the human body with five organs as the center, through the meridian communication, qi and blood infusion, the six internal organs, official orifices, limbs and bones, tendons, veins, flesh, skin and hair, bone connected into an organic whole. Second, people and nature are an organic whole. Changes in nature (such as seasonal climate, day and night, morning and evening, regional areas, etc.) can directly or indirectly affect the human body, and the human body adapts to the changes in nature and changes accordingly. Third, the unity of human and social environment. The social environment mainly includes social, political, economic and cultural behavior, group mental state and lifestyle. People are an integral part of society, and changes in social environment factors, especially social stability and turmoil, progress and backwardness, personal status and changes in society, wealth and poverty, all directly or indirectly affect the health status of the human body and even lead to the occurrence of diseases. The understanding of the human body in TCM is guided by a holistic concept, which comprehensively and dynamically grasps the physiological and pathological information of the human body, focuses on the balance of the yin and yang of the human body, the coordination of the internal organs, the unity of the form and the spirit, and the correspondence between heaven and man, focuses on the internal constant movement of the human body and the harmonious state of existence with nature, society and the environment, and forms the treatment theory and practice of holistic regulation. This holistic treatment approach, such as helping to eliminate evil, treating both the symptoms and the root cause, benefiting Qi and invigorating blood, nourishing liver and kidney, etc., has obvious advantages in treating chronic diseases with complex causes and multiple internal organs, especially in the treatment of chronic diseases at risk where modern medicine lacks effective diagnosis and treatment models. 3. Early intervention under the concept of treating the untreated disease The concept of treating the untreated disease in Chinese medicine includes “preventing the untreated disease before it occurs”, “preventing changes after the disease has occurred” and “preventing recurrence after the disease has occurred”. It emphasizes the importance of taking care of the body, protecting the righteousness, and improving the body’s ability to resist diseases, so as to prevent the occurrence of diseases before getting sick, prevent the further development of diseases after getting sick, and prevent recurrence of diseases after being cured. The concept and method of early intervention in health maintenance, health care, treatment and rehabilitation can effectively achieve the purpose of health maintenance, disease prevention and treatment. 4, the effect of comprehensive intervention of Chinese medicine for the long duration of chronic diseases, multi-organ damage, Chinese medicine has the characteristics of simple, convenient, experimental, inexpensive, safe, can better play the advantages of overall regulation, comprehensive intervention, more suitable for the decline in the function of internal organs, poor metabolic function, the vast number of middle-aged and elderly people suffering from chronic diseases. The treatment of chronic diseases is to systematically understand the human body under the guidance of the holistic concept and the theory of evidence-based treatment, to establish individualized treatment plans for different disease states of the body, and to gradually restore the body to a healthy state of balance between yin and yang; under the guidance of the theory of treating the disease before it occurs, to “prevent the disease before it occurs” and reduce the incidence of chronic diseases by addressing the dangerous state of the body; to improve Under the guidance of the theory of treating the untreated diseases, we can prevent chronic diseases before they occur and improve the early intervention measures for the prevention and treatment of chronic diseases to improve the quality of life of patients with chronic diseases and thus reduce the mortality rate of chronic diseases. The theory and practice of TCM in the treatment of chronic diseases have certain advantages, such as reliable efficacy, low toxic side effects and relatively low cost, especially focusing on the overall regulation of human body functions, stimulating the body’s ability to resist and recover from diseases, which is conducive to the comprehensive treatment and recovery of chronic diseases with complex causes. Vigorously promote the application of appropriate techniques and methods for the prevention and treatment of chronic diseases in Chinese medicine is of great significance to the control of chronic diseases.
