I. Epidemiology Chronic obstructive pulmonary disease (COPD) is a serious health hazard for people, with a current prevalence of about 6-10% in the world population and a 9.1% prevalence of COPD in people aged 40-69 years in Europe. In the United States, the National Health Survey found a 6% prevalence of COPD in people over 25 years of age [24]. In Asia, an epidemiological survey in Japan in 2001 showed that the prevalence of COPD was 8.5% in people over 40 years of age [25], and a survey in Guangdong Province in 2005 showed that the overall prevalence of COPD was 9.4% [27]; the prevalence of COPD in the elderly in Shanghai was 12.11% [28]. The latest epidemiological survey showed that the prevalence of COPD in people over 40 years of age in China is as high as 8.3%]. In terms of morbidity and mortality, COPD kills 100,000 people each year in the United States, accounting for the 4th leading cause of death in the United States. In Europe, COPD is the third leading cause of death along with asthma and pneumonia. In China, respiratory diseases (mainly COPD) accounted for 12.6% of major deaths in urban areas in 2005, ranking 4th, and 23.5% in rural areas, ranking 1st. The global COPD mortality rate is expected to rise from the 4th in 1990 to the 3rd by 2020, and COPD is expected to be the 5th most economically burdensome disease in the world by 2020. In recent years, the morbidity and mortality rates of COPD have been on the rise globally, and with the advent of an aging society, the prevention and treatment of COPD has become a public health issue of widespread concern worldwide. COPD is a preventable and treatable disease characterized by airflow limitation, which is not completely reversible and progressive, and is associated with an abnormal inflammatory response of the lungs to harmful gases or particles such as cigarette smoke, and mainly involves the lungs, but can also cause systemic adverse effects. …… COPD onset is closely related to chronic bronchitis and emphysema Three, clinical manifestations: chronic cough and sputum, shortness of breath after activity is its main feature, there are also patients without obvious cough, only chest tightness and shortness of breath after activity. (1) Chronic cough, the patient often has a chronic cough, heavier in the morning or the whole day, repeated episodes (2) Coughing sputum: usually cough a small amount of mucus foamy sputum, more in the early morning; sputum volume increases when combined with infection, and purulent sputum. (3) Shortness of breath or dyspnea after activity: It is the hallmark symptom of COPD. (4) Wheezing and chest tightness: tightness in the chest usually occurs after exertion. (5) Systemic symptoms: In more severe patients, systemic symptoms may occur, such as weight loss, loss of appetite, peripheral muscle atrophy and dysfunction, mental depression and/or anxiety, etc. COPD mostly belongs to the categories of “cough”, “asthma”, “lung distension”, “phlegm” and “phlegm-drinking” in Chinese medicine. The Chinese medical science of COPD is mostly in the categories of “cough”, “wheezing”, “lung distension”, “phlegm”, etc. It is believed that the pathogenesis of COPD is due to chronic bronchitis, emphysema and other diseases that persist, spleen and yang deficiency, phlegm and dampness within the lungs, and lung qi stagnation, which become the basis of the disease. The deficiency of the lung and the lack of solidity of the lung guard, as well as the repeated attacks of external evil, improper diet, emotional disorders, and excessive labor and fatigue, induce the attack of the disease and its progressive aggravation. This eventually leads to dysfunction of multiple internal organs, including the lung, spleen, kidney and heart. Danxi Xinfa? Cough: “The lung is distended and coughing, or the left or right cannot sleep, this phlegm is held as a series of symptoms such as chronic cough, coughing and wheezing that do not heal, and the blood stasis hinders the qi and the disease.” It is clearly pointed out that phlegm and stasis in the lung and stagnation of lung qi are the basic pathogenesis of this disease. This shows that phlegm, stasis and organ deficiency are the main pathological factors of COPD, and also the root cause of the disease’s prolongation, recurrent attacks and persistence. In our opinion, qi deficiency is the main factor in the stable stage of COPD, and lung qi deficiency is an intrinsic factor in the development of COPD. Phlegm and stasis are important pathological products and pathogenic factors in the course of the disease. What are the causes of COPD? It is said in the Treatise on Asthma: “The cause of lung distension is internal stagnation, which first hurts the lung qi, and then the lung qi is not allowed to be released due to the external infection, so the lung distension is made. Lung Qi deficiency, unable to promote the flow and distribution of fluid, fluid stagnation, will produce phlegm and water-dampness; Spleen Qi deficiency, dysfunction of transportation and transformation, fluid can not be distributed, gathered into phlegm, injected into the lungs, resulting in coughing and coughing phlegm. Therefore, “the spleen is the source of phlegm, and the lungs are the reservoir of phlegm”. The kidney is the master of the Yang energy and has the function of warming water and dampness. Chen Xiuyuan “medical from the record” said: “phlegm of the original, water, from the kidney; phlegm of the function, wet, the main in the spleen; phlegm of the line; gas; storage in the lungs.” When phlegm and dampness obstruct each other, the qi mechanism becomes unregulated, resulting in qi stagnation and qi reversal; and because qi and blood have mutual roots, qi stagnation leads to blood stasis, and phlegm obstructs blood flow, also leading to blood stasis. The pathological factors in the stable stage are mainly qi deficiency, with the initial disease location in the lung and the later disease location in the lung and kidney. If the lung is deficient for a long time, the son steals the mother’s qi, and the spleen loses its health, it may lead to deficiency of lung and spleen qi; if the disease is repeated and prolonged, the lung and kidney will be deficient, and the mother’s disease will affect the son. The disease is mostly a deficiency of the root and the symptoms of the disease, and is complex, prolonged and long-lasting. The main manifestation of this deficiency is in the stable stage, and the disease is mainly located in the lung, spleen and kidney. For the treatment of COPD, medical practitioners have emphasized the treatment of the symptoms by removing the evil during the acute attack, and the treatment of the root cause by supporting the deficiency during the stabilization period. Based on our years of clinical experience, we have proposed a dialectical concept of four categories and eight evidence: acute, slow, deficiency and actual. In other words, the disease is divided into the acute exacerbation period and the remission period, and the evidence is divided into deficiency and actual symptoms, wind-cold attacking the lung, external cold drinking, lung-heat offending the lung, phlegm-heat congestion in the lung, phlegm-dampness, phlegm clouding the lung, lung qi deficiency, lung-spleen deficiency, lung-kidney deficiency. The lung, spleen and kidney deficiency evidence, lung and kidney yin deficiency evidence; and self-designed formula to tonify the kidney, strengthen the spleen and benefit the lung. It has good effects in reducing the number of colds, inhibiting the release and synthesis of inflammatory mediators, and improving the immunity and quality of life of the body, reflecting the advantages of holistic treatment of TCM. In recent years, with further research on COPD, Chinese medicine has made in-depth progress in the treatment of COPD, and its advantages in clinical practice are becoming more and more obvious. It is mainly reflected in the acute exacerbation period using a combination of Chinese and Western medicine treatment, can significantly improve the efficacy, significantly shorten the course of the disease,; V. Chinese medicine treatment: According to our clinical experience, the slow obstructive pulmonary is divided into two categories of eight types of symptoms, and follow the principle of acute and slow for then deficiency and real for the outline, acute is the treatment of the symptoms slow is the treatment of the principle of the clinical effect. The effect of this formula on the pulmonary ventilation function of patients with COPD in remission was observed, and the quality of life of patients in the treatment group was improved through clinical observation. In the acute exacerbation period (mixed deficiency and reality), wind-cold attacking the lung, external cold and internal drinking, Ma Huang Tang, Xiao Qing Long Tang, Hua Gai San, plus or minus Lung heat offending the lung, phlegm-heat congested lung, Ma Xing Shi Gan Tang, Sang Bai Pi Tang, plus or minus Phlegm-dampness, phlegm-obstructing the lung, Er Chen Tang, San Zi Yang Yin Tang, Su Zi Descending Qi Tang, plus or minus. Yu Ping Feng with Liu Wei Di Huang, Jin Gui Kidney Qi Pill plus or minus Evidence of deficiency of lung, spleen and kidney: Tonic Zhong Yi Qi, Ginseng and Atractylodes, Jin Kui Kidney Qi plus or minus Lung and kidney yin deficiency evidence: Seven Flavors Du Qi Pill and Nourishing Yin and Clearing Lung Pill plus or minus. Through years of clinical practice we have conducted clinical observation on COPD for many years and formed our own formula to tonify the kidney, strengthen the spleen and benefit the lung, mainly also on the basis of tonifying the kidney, strengthening the spleen and tonifying the lung, and treating each patient’s specific situation and syndrome type with evidence, and achieved good results. For phlegm and dampness, add Chen Pi, Sempervivum, Poria, Atractylodes, Job’s Tear, Hou Pu, etc. For lung heat, add Scutellaria, Forsythia, Fritillaria, Gypsum, Tiger Balm, etc. For Yang deficiency: add Radix Bupleuri, Epimedium, Bacopa monniera, etc. For Yin deficiency: add Radix et Rhizoma Ginseng, Dendrobium, etc. In addition, COPD patients should pay attention to comprehensive treatment, for example, currently take: education and management; control occupational or environmental pollution, avoid or prevent dust, smoke and harmful gas inhalation; inhalation medication such as: Sulidex, Symbicort, ipratropium bromide aerosol, tiotropium bromide powder inhalation; oxygen therapy. For poor lung function and hypoxia, small flow intermittent oxygenation, adherence to rehabilitation and surgical procedures, etc. At present, the clinical treatment plan combining Chinese and Western characteristics of COPD has been formed, which has achieved better clinical efficacy and demonstrated a good prospect for the treatment of COPD.
