| Purposes: By comprehensively and systematically sorting out and studying the last twenty academic thoughts of Yu Lin’s "Epidemic Rash I De Juan Xia",this paper summarizes the understanding,syndrome differentiation system,treatment methods,prescription and drug characteristics of the last twenty articles of "Epidemic Rash I De Juan Xia" and their enlightenment to contemporary infectious diseases,with a view to enlightening the present era.Methods: This paper adopts the research methods of combining traditional literature research,theoretical discussion and data mining,and summarizes the academic characteristics of Yu Lin’s treatment of postepidemic diseases in the aspects of "principle,method,prescription and medicine",and deeply digs into the main methods and characteristics of treatment of post-epidemic diseases,so as to explore Yu Lin’s understanding of future generations in his academic thoughts on treatment of post-epidemic diseases.Results : Yu Lin ’s " epidemic rash " has a rich thought and theory of recuperation after epidemic disease,and has a unique understanding of the occurrence,development and treatment of various diseases after epidemic disease.Yu ’s thought of treating various diseases after epidemic disease has enriched the content of the theoretical system of traditional Chinese medicine,and has theoretical guiding significance for preventing major infectious diseases and epidemic diseases.1.Through literature review,it can be known that the discussion of various symptoms after epidemic disease was first discussed in Huangdi Neijing in the Spring and Autumn Period.The word "qi" refers to the fact that he has just recovered from illness and is in the recovery period of the body,with deficiency of qi and blood in the viscera,stagnation of qi,disharmony of qi in the spleen and stomach,and failure to recover vital qi.In Treatise on Febrile Diseases,Zhang Zhongjing specially discusses the changes of yin and yang,fatigue recovery,food recovery,residual heat,cold retention and qi and yin deficiency,and points out the corresponding treatment methods and prescriptions.During the Jin Dynasty,Ge Hong added two aspects: prevention after recovery and diet avoidance.In the Sui and Tang Dynasties,the Secret of Outer Taiwan Volume III discussed in detail that diet should be avoided after epidemic disease,and pointed out that eating related foods would cause adverse reactions.During the Song,Jin and Yuan Dynasties,Wang Huai made a distinction between post-epigastric diseases and the theory of ghosts and gods,and put forward corresponding prescriptions to treat them.The Ming and Qing Dynasties saw the peak of the development of the theory of epidemic diseases,with the emergence of experts on epidemic diseases such as Ye Tianshi,Wu Youke and Dai Tianzhang.Their academic ideas were that after the epidemic diseases,the patients were deficient in both qi and yin,and the afterheat was not enough,so they should rest and recuperate.On the basis of predecessors,modern physicians mainly treated various diseases after the epidemic diseases by promoting fluid production,nourishing fluid,tonifying qi and yin,and purging afterheat.2.Through data mining,it can be found that Yu’s drugs for treating various diseases after the epidemic disease are licorice,ginseng,angelica,jujube,poria cocos,atractylodes macrocephala,polygala tenuifolia,etc.and the composition of the drugs is similar to that of Guipi decoction,which shows that Yu believes that the main symptoms after the epidemic disease are deficiency of both qi and blood,which is related to the injury of body fluid,qi and yin,spleen and stomach yin,and spleen and stomach yin.Corresponding to the symptoms related to shortness of breath and lack of energy after epidemic disease,the drug taste is mainly sweet,and the efficacy of taking sweet drugs to tonify,moderate and urgent is consistent with the syndrome types after epidemic disease.The results of high-frequency drug association rules show that 23 groups of two related drug pairs,20 groups of three related drug pairs and 6groups of four related drug pairs are obtained,among which ginseng →polygala tenuifolia+poria cocos+angelica sinensis are used more frequently.3.Yu’s treatment of post-epidemic diseases is based on five basic principles: paying attention to the spleen and stomach,caring for middle qi and yin deficiency with heat,nourishing yin and clearing heat,deficiency of both qi and yin,benefiting qi and nourishing yin,failing to communicate between heart and kidney,communicating between heart and kidney and preventing recurrence,and treating the symptoms discussed in the last 20 articles according to five categories: tonifying the spleen and stomach,nourishing blood and calming the nerves,cleaning up residual heat,communicating between heart and kidney and preventing recurrence.4.The last 20 articles of Yu’s "Epidemic Eruption,Volume-down" enlighten the symptoms after epidemic diseases nowadays,including the symptoms after epidemic diseases,and the first one is stomach qi,which directly affects the symptoms after epidemic diseases,and the strength of stomach qi is directly related to the body fluid of patients after epidemic diseases,and critical emergency occurs after epidemic diseases.After the epidemic disease,we should guard against recurrence,prevent food recovery,make diet appropriate and taboo,prevent fatigue recovery and yin-yang recovery,protect essence and kidney,control desire and not work in vain.Drug use after epidemic disease should be based on the physical condition of the patient’s family,so as to be used with the syndrome.According to Yu’s post-epidemic academic thought,general and symptomatic treatment prescriptions are made for post-epidemic diseases of novel coronavirus,Japanese encephalitis and infectious atypical pneumonia.Conclusion: Yu Lin’s Yi Pi Yi De has rich experience in treating postepidemic diseases,which provides important enlightenment for the treatment of post-epidemic diseases,and has rich value and significance.1.Yu Lin’s post-epidemic conditioning thought focuses on stomach qi.At the same time,he thinks that the excess of pathogenic heat after epidemic disease mainly consumes lung,stomach and body fluid.If the pathogenic heat is not removed,the liver and kidney will consume liver blood and kidney essence for a long time.After epidemic disease,we should replenish qi and nourish yin,communicate with heart and kidney and prevent recurrence.At the same time,we should pay attention to the syndromes of deficiency of both qi and yin,heart and kidney disharmony and recurrence after epidemic disease.2.After the epidemic disease in Yu Lin,the treatment was carried out around five parts: nourishing the spleen and stomach,nourishing blood and calming the nerves,cleaning up residual heat,communicating the heart and kidney and preventing and recovering after the epidemic disease.Ginseng,Angelica sinensis,Jujube,Poria and Atractylodes macrocephala were mostly used in combination.3.There are many sequelae in modern novel coronavirus.According to the experience of diagnosis and treatment after Yu’s epidemic disease,we should pay attention to stomach qi,avoid eating and control eating,and abstain from sex in spirit to prevent fatigue and sexual recovery.At the same time,according to the constitution,we should use drugs based on syndrome differentiation.For example,patients with qi deficiency can supplement qi and deficiency,and COVID-19 Hou can use Shengmai Powder and Pingwei Powder as general prescriptions for treatment,and use Shashen Maidong Decoction and Zhigancao Decoction for clinical treatment. |
