Pneumonia and cough is one of the common clinical diseases in pediatric patients, with fever, cough, shortness of breath and nasal incitement as the main features. It is equivalent to pneumonia in Western medicine. Because the lung is the source of water, so the early stage of the disease, external evil dry lung, must produce drinking evil, so drinking evil is an important pathological factor in the early stage of the disease, in the occurrence, development and regression of pneumonia cough plays an important role. Pediatric pneumonia cough early drinking evil ten in seven or eight, and hot drinks and eight or nine of them, the doctor does not notice, only know to clear heat and phlegm and do not know “warm medicine and the”, resulting in drink brewed into phlegm, the disease is prolonged. Early identification and treatment of hot drinks, not only can be rafter effect, but also can cut off the reversal, reflecting the idea of “treating the untreated disease”, and enriching and innovating the Chinese medicine treatment system for this disease. Now, without trying to be shallow, shallow analysis of the following, for the benefit of fellow practitioners. First, the key to the initial pathogenesis of pediatric pneumonia and wheezing: hot drinks blocking the lungs Drinking evil, is caused by the weakness of Yang Qi, gas does not turn into fluid, fluid condensation and, according to the different parts of its stay, and the symptoms are different. In the Nei Jing, there are only records of “watery drink” and “accumulated drink”. Zhang Zhongjing created the name “phlegm drink” on the basis of the theory of “Nei Jing”, and divided it into four categories: “phlegm drink, overflow drink, hanging drink, branch drink”. Because the spleen is the source of phlegm (drink), the lung is the storage of phlegm (drink), and children’s internal organs are delicate, the form of Qi is not yet full, the lung is often insufficient, so the drink is the main causative factor of lung disease in children. Drink and according to its etiology and pulse evidence is divided into cold and hot drinks, because “cold drinks easy to know, hot drinks difficult to know” (Chengmen Xue language), so the doctor only see the cold drink and ignore the hot drink. In fact, about hot drinks, ancient doctors have long discussed. Yu Jiayan said: “drink because of the wet, there are hot and cold.” The temperature of the disease, the cloud “wheezing and coughing, spitting thin saliva, pulse flooding, right is greater than the left, throat dumb, is the hot drink. You in the Jing in the note Wu Ling San said “hot thirsty drinking water, water into can not have its heat, and heat also can not eliminate its water, so water and heat knot. The author hot clinical evidence seen, pediatric lung disease at the beginning of the drinking evil ten in seven or eight, and hot drinks and eight or nine of them. Based on the characteristics and transformation of phlegm and beverage relationship and the unique pathophysiological characteristics of children proposed hot drinks blocking the lung is the key to the initial pathogenesis of paediatric pneumonia and cough. First of all, phlegm and beverages are a type of disease in which the Qi transformation of the three jiao is unfavorable, and the water is not properly transported and distributed in the body, and accumulates in certain parts. Before the Sui and Tang dynasties, phlegm and drink are not clearly distinguishable, until the Song dynasty Yang Renzai “straight to the formula” is phlegm and drink are divided into two. Since then, the medical practitioners more than its said, that the thick and turbid for phlegm, clear and thin for the drink. According to the author’s experience in the treatment of pediatric pneumonia and cough for many years, phlegm and drink can be transformed between, generally more than the formation of drinking evil in the first, after the heat of the evil steam refining decoction into phlegm evil, that is, refining drink into phlegm; or by cold evil cohesion solidified into phlegm evil, that is, condensed drink for phlegm. According to the above, the nature of the drinking evil is thin and light, mostly in the early stage of the disease. In the early stage of paediatric pneumonia and coughing, the cough and saliva are clear and thin, and the lungs are mostly auscultated with wet rosacea (blistering sound), which is in line with the understanding of Chinese medicine that “clear and thin is drink”, and combined with the experience that drink becomes first in the early stage of lung disease, we can know that drink is the key to the pathogenesis of paediatric pneumonia and coughing. Secondly, pediatric lung disease drink evidence hot drink evidence is predominant, as Yu Jiayan had cloud “exactly drink evidence, hot damp brewed into more, cold damp brewed into less.” Pediatric unique physiopathological characteristics determine the key to the pathogenesis of pediatric pneumonia and wheezing hot drinks blocking the lungs. Children’s organs are delicate, the shape of gas is not full, the lungs (spleen) is often insufficient, Yang Qi is deficient, water is easy to drink, once sick, parents and doctors like to use cold medicine to clear the heat, and fear to throw warm agents to warm, resulting in Yang Qi more deficient, for a long time the child Yang Qi internal deficiency of this gradually become. Contrary to the treatment of the disease, the child’s diet is spicy and thick, or even warm tonic, or will be too warm, so that the standard of internal heat evil is formed. In short, there are three mechanisms that lead to the formation of hot drinks in pediatric lung disease: first, cold drinks at the beginning, depression and heat The lung is the source of water, the child’s lung is often inadequate, and the regulation of the failure, the water stops as a drink, depression and heat, or with the heat of the body, the development of hot drinks; second, the lung is cold drinks, and then feel the external evil There are cold drinks in the lung, and then feel the external evil, and into the drink with the evil, depression and heat, that is, hot drinks; third, drink and heat are knotted together, on the overriding The spleen is often deficient in children, the transport and transformation of the failure, water and drink, or lead to drink too much, water and drink do not transform, hot drinks, hot drinks intertwined, up over the lung, hot drinks from the birth. In summary, the essence of the hot drink evidence for this deficiency, Yang deficiency for its origin, heat is its standard, Yang deficiency, water and dampness is not warmed, drinking evil, and then with the heat of the interjunction, blocking and the lung, the lung is not to promote the suction, and become lung disease. Second, the key points of identification of heat-drinking evidence: the heart of the Chinese ginseng west that, identification is the basic principle of Chinese medicine to understand the disease, but also a special method of Chinese medicine to identify and judge the disease, that is, through the look, smell, ask, cut the collected information, symptoms and signs, through analysis, synthesis, judged as some kind of evidence, in order to explore the nature of the disease. However, due to the limitations of scientific conditions, the four diagnoses of ancient Chinese medicine are only based on the perception and experience of the five senses, and sometimes it is difficult to discover deep or potential pathologies, which has great limitations, which is not only a problem that the ancient sages could not foresee, but also a problem that our contemporary Chinese medicine cannot avoid. Therefore, in today’s highly developed modern technology, it is necessary to reasonably apply modern diagnosis and treatment techniques to further extend the four diagnoses of TCM, in order to make up for the shortcomings of TCM diagnosis, which not only does not deviate from the way of TCM diagnosis and treatment, but also complements and perfects the system of diagnosis and treatment. Therefore, the author believes that the key point of identification of hot drink evidence is to refer to the Western medical auscultation, i.e., to make reference to Western medicine, specifically in the following three aspects: First, lung auscultation Smell diagnosis is a method to diagnose disease by listening to sound and smell, which is one of the important methods of Chinese medicine to diagnose disease, such as “Nei Jing” said “smell and know is called sage”. In ancient times, Chinese medicine practitioners only “smelled” diseases by their ears and nose, but in modern times, with the help of stethoscope, it is a further development of ancient Chinese medicine diagnosis, to improve the level of “smelling” diagnosis of internal sounds. According to the author’s clinical experience, the wet sound (i.e. blistering sound) heard with the help of stethoscope is considered by western medicine to be related to the obstruction of the airway with thin secretions, which is similar to the so-called “clear and thin is drinking” in Chinese medicine, and is judged to be drinking evidence; on the contrary, the dry sound heard is considered by western medicine to be related to the sticky phlegm adhering to the airway, which is similar to the so-called “thick is phlegm” in Chinese medicine. On the contrary, the dry rhododendron heard is considered by Western medicine to be related to sticky phlegm adhering to the airway, which is consistent with the so-called “thick phlegm” in Chinese medicine, and is judged as phlegm evidence. Secondly, the clinical symptoms of pulmonary disease hot drink evidence are more complicated, in fact, both hot and drink evidence are available, and there is also an essential difference with phlegm-heat evidence. The main manifestations are fever, coughing and salivation, mouth full of fluid, taste light but not fishy, dry mouth but not desire to drink, irritability, or with vomiting, abdominal distension, diarrhea. Because of heat, so fever, irritability, dry mouth, because of drink and heat, so dry mouth but do not want to drink, coughing and salivation, thin quality, light taste and not fishy odor or with vomiting, abdominal distension, diarrhea, etc. are all drink evil within the stop of the marquis. Third, the tongue and pulse The typical tongue and pulse of children with lung disease with hot drink evidence is a light tongue with a slight yellow coating and a tight pulse or number. Third, the key to the treatment of hot drink evidence: treatment with the evidence Zhang Zhongjing “Jin Kui Essentials” phlegm cough disease pulse evidence and treatment chapter said “the disease phlegm drink, when the warm medicine and the.” The term “phlegm-drinking” does not refer to “phlegm evidence” but specifically to “drinking evidence” [1], so it can be regarded as the general outline of the treatment of drinking evidence. In the author’s opinion, the treatment of hot-drinking evidence should follow the principle of “observe the pulse and evidence, and treat it according to the evidence”. Because the Yang deficiency for pediatric lung disease hot drink evidence of the root, drink for yin, easy to hurt Yang, non-warm, so the treatment should be warming. But hot drink evidence is different from the simple drink evidence, heat for its hot drink evidence of the mark, non-clear and cool not remove, if only throw warm tonic, there is no not ruin the matter, treatment is appropriate to warm the main, warm and cool, in clearing the heat in consideration of its Yang deficiency and weakness of the original, to make sure that the heat evil clear and Yang is not hurt, drink evil and not help the heat evil. In the evidence of hot drink evidence of heat and drink evil, the hot drink evidence of paediatric pneumonia and cough is divided into three types of evidence: drink over heat evidence, heat over drink evidence and both drink and heat evidence for evidence-based treatment, often with rafter effect. Specifically, for the evidence of heat-over-drinking, Xiaoqinglong plus gypsum soup is used, in which dry ginger, silybin, cinnamon branch and half-xia are mainly used to warm watery drinks, and raw gypsum is added to clear the heat, and if the stool is dry, more rhubarb is added to cleanse the stomach and intestines and induce the downward flow of drinks; for the evidence of heat-over-drinking, Yuejian plus half-xia soup is used, in which ephedra and raw gypsum are used to clear the heat, and ginger and half-xia are used to disperse watery drinks, and light bamboo leaves are added to clear heat and facilitate drinks; for the evidence of heat-over-drinking, the formula is used In this formula, the formula is based on the use of Ma Heng Shi Gan and Ling Gan Wu Wei Jiang Xin Tang to clear lung heat and Ling Gan Wu Wei Jiang Xin Tang to warm cold drinks. Hot drink evidence is different from the treatment of phlegm-heat evidence, the use of bitter cold medicine to clear heat and resolve phlegm, such as scutellaria, Huanglian, South Star of the genus. Because of hot drink evidence of Yang deficiency, cold too much, more injury to Yang, but make it difficult to drink evil, drink evil should be dispersed and not guarded, so the use of drugs to clear heat both flow of drugs, such as gypsum, rhubarb, etc.. Among them, gypsum smell pungent sweet cold, pungent is going and not guard, cold can clear heat, so clear heat without the disadvantages of cold containment; rhubarb smell bitter cold, the ancients called the General, has the function of felling the evil to chaos, “Ben Jing” said its “cleanse the intestines and stomach, push the old to the new, through the water and grain”. In addition, the author prefers to use light bamboo leaves, because this product is sweet and light cold, cold can clear heat, light can facilitate the drink, with both the symptoms and the root cause of the treatment. In summary, when discussing the treatment of hot drinks, as long as we adhere to the principle of “observe its pulse and evidence, with the evidence of treatment”, the use of warm and cool, can be rafter effect. It should be noted that hot drinks for a long time, refining drinks into phlegm, for disease progression, when the phlegm evidence from the treatment, not gum column drums, resulting in a variety of evidence.
