Bronchial asthma (asthma for short) is a chronic, recurrent, allergic inflammatory disease of the respiratory tract that poses a serious threat to human health worldwide, and its incidence and mortality rates are increasing year by year [1]. The numerous etiologies and complex pathogenesis of asthma, especially the wide variation of individual children themselves, make the prevention and treatment of asthma, especially the eradication, more difficult. Currently, Western medicine is mainly concerned with suppressing and clearing airway inflammation, and the inhalation of glucocorticoids has become the preferred treatment for asthma [2], but long-term application brings a series of problems that cannot be ignored [3], [4] and is expensive. Pediatric asthma is different from adults, and the existing drugs are less effective in children with asthma, especially in small infants, and it is difficult to achieve the expected results [5] 1. Chinese medicine understanding of asthma Chinese medicine believes that the main cause of asthma is the presence of volatile phlegm in the body, and the main reason for the production of volatile phlegm is the insufficient function of the lungs, spleen, and kidneys of the vegetative body, i.e., this physical state of the congenitally determined insufficient function of the lungs, spleen, and kidneys is the main basis for the occurrence of asthma. In clinical practice, we have observed that most children with asthma have a history of atopic diseases and family history, i.e., it is suggested that the physical status of the family influences the occurrence and development of asthma. The pathology of asthma attacks is phlegm and qi obstruction, and it is difficult to eradicate the pathology because of various factors such as the difficulty in removing the volatile phlegm, the difficulty in preventing external evil, and the difficulty in identifying the hair, which are closely related to the physical status of the vegetative lung, spleen and kidney deficiency. The reason why it is difficult to cure recurrent asthma attacks is that this congenital state of the body (i.e. the vegetative body) is difficult to regulate. Therefore, the study and understanding of this physical state of children with asthma, so as to regulate it, has become a very critical part of the prevention and treatment of pediatric asthma. Chinese medicine emphasizes that the treatment of asthma should not only be aimed at controlling the symptoms by eliminating phlegm and lowering qi during the attack period, but also at eliminating phlegm in the body by correcting the deficient lung, spleen and kidney during the remission period, which is consistent with modern medicine’s belief that chronic inflammation of the airways still exists during the remission period of asthma and the emphasis on long-term inhalation of hormone anti-inflammatory during the remission period. Our research on the physical status of asthmatic children also confirms that most asthmatic children have the physical status of lung, spleen and kidney deficiency, therefore, improving the physical status of lung, spleen and kidney deficiency is the most crucial part of asthma prevention and treatment [6]. It is believed that constitution is the relatively stable functional, structural and metabolic peculiarities of the population and individuals in the population based on heredity and formed during their growth, development and aging, which often determine their susceptibility to certain disease-causing factors and their tendency to develop pathologies [7]. Since the systematic organization and establishment of the TCM constitution theory in the 1970s, from theoretical construction to clinical application, and from group research to continuous advancement of basic research, it has been recognized that constitution is a relatively stable personality characteristic with variability. Modern pharmacological experiments and clinical observations have initially verified the concept of “physique modifiability” [8]. In addition, living conditions and diet, geographical environment, physical exercise, mental factors, social factors, etc. can improve and influence the physique or even change it [9]. 3.1 Yin and Yang theory of pediatric physique In the theory of pediatric physique, there is the theory that children are “pure yang” and “infantile yin and infantile yang” [10]. Ancient medical practitioners borrowed the term “pure yang” from the I Ching to express the physical characteristics of the pediatric period to indicate that the yin and yang of the pediatric organism are dominated by the tendency of yang growth. The term “infantile yin and infantile yang” was proposed by Wu Jutong, a Qing dynasty physician, in his “Discernment of Warm Diseases” to illustrate the immaturity and imperfection of the infantile period, both in terms of the form and quality of yin and the various physiological activities of yang. The doctrines of “pure yang” and “infantile yin and infantile yang” in pediatrics were gradually formed with the development of the practice of pediatric medicine in Chinese medicine. The “infantile yin and infantile yang” doctrine is a refinement and supplement to the “pure yang” doctrine. They are based on the basic theory of yin and yang and show that although the yin and yang of children’s physique are not mature and perfect, they show a tendency to be dominated by “Yang Sheng”, which has become the basic guiding theory of TCM pediatrics. 3.2 The Five Organs Theory of Pediatric Physique Wan Quan, a famous pediatrician of the Ming Dynasty, proposed that “among the five organs, the liver has a surplus, the spleen is always deficient and the kidneys are always deficient, the heart is hot and fire is the same as the liver, and the delicate lungs are not easily healed by injuries”. The surplus and deficiency of the five organs in children is not a pathological surplus and deficiency, but a relative expression of the “pure yang” and “infantile yin and yang” bodies in the physiological characteristics of the five organs. It also determines the characteristics of pediatric morbidity, for example, lung, spleen and kidney are the most common in pediatrics. At the same time, because the strength of the body’s positive qi is most closely related to the lung, spleen, and kidney, and the lung, spleen, and kidney are relatively deficient among the five organs in children, the “positive qi” is not yet full and perfect, and the ability to resist diseases is not full and perfect, so they are more prone to various diseases than adults [11-13]. 3.3 Pediatric body type Su et al. divided the pediatric body type into balanced and unbalanced, and the unbalanced type was specifically divided into lung-spleen type I and II; spleen-kidney type I and II. 1016 cases of pediatric body type were investigated, and the results suggested that there were different body types in the pediatric population with corresponding differences [14]. Zheng et al. used the identification of yin and yang qi and blood organs as the outline, combined with the physiological characteristics of children’s “spleen is always deficient”, and divided children into yin and yang qi and blood balance and concordance type (calm type), stagnant heat type, spleen and stomach qi deficiency type (qi deficiency type), and spleen and stomach yin deficiency type (yin deficiency type), and conducted a questionnaire survey on 2030 cases of children’s physique types, and analyzed from a specific perspective characteristics of pediatric physique [15]. 4 , the physical status of children with asthma Modern research suggests that various forms of asthma may be due to the same genetic defects, and that allergic constitution can increase asthma attacks, while asthma and allergic constitution have different genetic patterns, and in terms of clinical manifestations mainly lie in attack triggers, seasons of onset, attack precursors and different allergic diseases of the children themselves [16]. According to TCM, asthma attacks are closely related to the child’s physical state of deficiency of lung, spleen and kidney, which is adjustable. How can the theory of constitution be used to guide the prevention and treatment of pediatric asthma? We have investigated the physical status of 100 asthmatic children and found that more than 70% of asthmatic children have a history of specific diseases and similar diseases in first and second degree relatives; all asthmatic children are of unbalanced quality, among which the spleen and kidney quality is the most common, accounting for 80% of asthmatic children; the results of T-lymphocyte subpopulation test show that children with spleen and kidney quality The results of the T-lymphocyte subgroup test showed that children with spleen and kidney had varying degrees of immune deficiency, which is consistent with the Chinese medicine view that asthmatic children have a deficient vegetative body [6], and the findings also suggest that asthmatic children over the age of 3 years account for 77% of asthmatic children, indicating that in addition to congenital factors, the physical differences of asthmatic children are also influenced by acquired factors, such as daily care, diseases and drugs, suggesting that we should not only pay attention to drug treatment but also emphasize daily Conservation. The 21st century is the century of life sciences, medical model, medical tasks, development trends and research methods and means have undergone great changes. The current medical model is changing from the biomedical model to the biological-social-psychological model of holistic medicine, from disease-centered group medicine to human-centered individual medicine. The special laws of human life processes and individual differences in the population are receiving more and more attention. The task of medicine will shift from prevention and treatment of diseases to maintaining and enhancing health and improving the quality of human life. With the comprehensive study of the relationship between physique and disease, physiotherapy, which focuses on adjusting physique and restoring health, will be developed. At present, somatics should make full use of the advantages of its own theory, select several types of diseases, and conduct basic and clinically relevant research. Starting with the adjustment of physical constitution and aiming at improving clinical efficacy, it will provide a new way for the treatment of modern difficult clinical diseases, and drive the development of the discipline in this way. By combining the physical theory of TCM with the clinical prevention and treatment of children’s asthma, and by using the physical theory of TCM to explore the effective way to cure asthma by adjusting the child’s body, we can not only fill the research gap of physical theory on the prevention and treatment of specific diseases, but also improve the prevention and treatment of children’s asthma by TCM.
