There are three books, annotated Treatise on Febrile Diseases (volume 10), Treatise on Febrile Diseases (volume 3) and Treatise on Febrile Diseases (volume 1).
When interpreting Treatise on Febrile Diseases, Cheng Wuji analyzed its pathogenesis, treatment and prescriptions. Under the guidance of Neijing and its theory, Neijing, Neijing and Treatise on Febrile Diseases come down in one continuous line, which completely conforms to Zhongjing's original intention of writing books and becomes one of the main notes for later physicians to learn Treatise on Febrile Diseases. For example, Cheng explained in Treatise on Febrile Diseases: "Sun disease, excessive sweating, chronic diarrhea, bad wind, unfavorable urination, slight acute limbs, unfavorable flexion and extension, mainly Guizhi decoction and Fuzi decoction", "Sun disease, due to excessive sweating, and prolonged sweating, but wind is not harmful, is due to excessive sweating, but insufficient yang, and the skin is not straight." Neijing says: Bladder is the official of the state. If body fluid is hidden, it can be evaporated. It is not suitable for those who have bad urination and sweat, and those who have yang deficiency. The limbs are the foundation of all yang. If the limbs are a little anxious and have difficulty in flexion and extension, the yang will die and the body will fall off. "Acupuncture Classics" says: If fluid is lost, the bones will not bend and stretch. Add Guizhi Fuzi decoction to warm meridians and promote yang. "Here, the two original versions of Neijing quoted by Cheng Jia, one refers to Linglan Secret Sutra, and the other is Lingshu, also known as Jiujuan, which comes from Lingshu breathed his last.
Cheng Wuji's explanation of Zhongjing Fang is also explained by the theories of Neijing and Difficult Classic. For example, when he explained Guizhi decoction, he said that Neijing said: Xin Gan diverges into Yang, and Guizhi decoction is also a medicine of Xin Gan. Comment on Sini Decoction: "Neijing says: cold is evil in the interior, and sweetness is the cure for heat." He also said, "Cold and yin are prevalent, and the combination of pungent and hot is a sweet and hot agent, which can disperse the qi of yin and yang." The theory of four qi and five flavors of yin and yang used by Cheng here explains the meaning of Zhongjing's prescription, which is concise and clear. In particular, when explaining Xiaoqinglong Decoction, Cheng said: "Cold evil is on the exterior, and it will not go away if it is not sweet. Ephedra, Cinnamomum cassia twig and Glycyrrhiza uralensis Fisch are sweet and sweet to eliminate evil spirits. Water stops heart failure and kidney dryness. Neijing says: the kidney is bitter and dry, and the acute food is spicy and moist. Dried ginger, asarum and Pinellia are pungent, and moisten the kidney by moving. Cough and asthma, the lung qi is reversed. "Neijing" said: the lung wants to collect, and it is urgent to eat acid to collect. The acid of Paeonia lactiflora and Schisandra chinensis is used to collect qi and calm the lungs. " Cheng cited the classic method of dirty qi theory here to explain the mechanism of Xiaoqinglong Decoction in dispersing exterior and cooling interior.
Cheng Wuji has rich experience in clinical application and syndrome differentiation of clinical symptoms. For example, when he discussed the fever syndrome, he said, "It is said that fever occurs naturally between the skin, and a spring [6] becomes fever. If it is the same as hot flashes and cold fever, it is similar to irritability, including irritability. Hot flashes are sometimes very hot and timely. Cold, hot, hot, cold and hot, one after another. As for fever, it happens from time to time. " Cheng put forward the difference between fever and hot flashes, cold and heat and irritability. He said: "There are also fevers, but the severity is different, and the appearance is different. The so-called "depressive fever" means that the body is covered with a layer of feathers, indicating that its heat is also outside, so it is dispelled by sweating with Guizhi decoction. The so-called steaming heat means that if it is steamed by fumigation, it will be clear that its heat is included, so it will be cleaned with Tiaowei Chengqi Decoction. Its fever belongs to the exterior, which is caused by cold skin and stagnation of yang. Its fever is internal, that is, yang enters yin. Looking at the heat, sweat proves its discrimination. " Cheng distinguishes its different clinical manifestations from both exterior and interior, expounds its different pathogenesis, and puts forward the method of treating both exterior and interior.
In addition, Cheng Wuji's theory of trepidation distinguishes war from chestnuts, and there are internal and external differences. On the theory of four inverses, it distinguishes four inverses from limb coldness. In the theory of irritability, it distinguishes irritability from irritability, points out the difference between yin and yang, and puts forward the causes, such as the difference between yang deficiency indicating fire and yin deficiency indicating fire, and so on. All of them are carefully summarized on the basis of studying the original text of Treatise on Febrile Diseases and combining with personal clinical experience. Yan Qi commented on his contribution that "righteousness refers to all people who have not been enlightened before, and refers to the fractal analysis of fixed evidence.". The same but different is clear, and the specious is clear. There are internal and external diagnosis to relieve trembling, and there are yin and yang differences in irritability theory. The prophetic words and Zheng Sheng made the actual situation known, and the four opposites and ambiguities made the depth and similarity clear, starting with fever and finally making efforts. Every fifty articles are the purpose. This understanding is objective.
Cheng Wuji was one of the great scholars who studied Treatise on Febrile Diseases in Song and Jin Dynasties. He is the author of ten volumes of Notes on Treatise on Febrile Diseases, three volumes of Treatise on Febrile Diseases and one volume of Treatise on Febrile Diseases. These three books on febrile diseases are annotated, demonstrated and discussed, which are tenable, closely related and complementary. Cheng's extensive research, enjoying himself, and annotating and debating the classics created a precedent for annotating Treatise on Febrile Diseases, which made later generations understand the principles and uses of typhoid fever and promoted the spread and development of typhoid fever theory. He wrote ten volumes of Annotations on Treatise on Febrile Diseases, which is the earliest complete annotation on Treatise on Febrile Diseases. He occupies an important historical position in the history of medical development in China.
Cheng Wuji was the first physician to comprehensively annotate Treatise on Febrile Diseases, and at the same time, combined with clinical application, he analyzed the common symptoms of typhoid fever for clinical diagnosis. It occupies an important position in the history of typhoid fever research in traditional Chinese medicine and has a great influence on the typhoid fever school in later generations.
