Syndrome-Element Study Of The Three-Yang And Three-Yin Differentiation In Treatise On Febrile Disease

Objective: To modify and develop the syndrome differentiation of Three-Yang and Three-Yin discussed in the classic of Treatise on Febrile Disease.Methods: 1. To draw a conclusion synchronically and diachronically from the collected documents about the syndrome differentiation of three-yang and three-yin. 2. Analysis and modification is carried out about 381 items abstracted from texts that discuss the syndrome of three-yang and three-yin, and that were proofread by the Research Group of Treatise on Febrile Disease in Shanghai College of Traditional Chinese Medicine in 1976, thereby the syndromes and elements are abstracted and a framework of syndrome-elements are established. 3. 208 case reports are collected. With the extreme-yin syndrome in consideration, a theoretical examination and a quantitive diagnostic research are made with the aid of software named WenFeng's Computer-Aided Diagnostic System (3rd edition). 4. Experimental rat models are established, one of which produces cold-damp-deficient syndrome of extreme-yin disorders, the other excess of fu-organs due to heat of the intestines in yangming disorders. After this, indices involving morphology and other specific points are observed and measured.Results: 1. The six-meridian syndrome differentiation, which in Treatise on Febrile Disease refers to diseases of taiyang, yangming, shaoyang, taiyin, shaoyin and jueyin, is actually an alternative term for three-yang and three-yin syndrome differentiation. It is obvious from the original texts of Treatise on Febrile Disease that differentiating syndromes of three-yin and three-yang are to locate the disorders and to determine the nature of the diseases. 2. Analyzing the three-yin and three-yang syndromes by use of syndrome-element differentiation may obtain more accurate results such as a larger coverage of the texts mentioned above, an easily-controlled direction in differentiating syndromes, unified results from syndrome differentiation, standardized features for each of syndromes and elements, clear connotation and denotation of terms, etc. As a result, the long-time confused conditions in the research of Treatise on Febrile Disease may be overcome. 3. Wenfeng's Computer-Aided Diagnostic System has capability in promoting the accuracy of syndrome differentiation and it ascertains the argument that syndromes of Treatise on Febrile Disease can be the generalization of various types of diseases. 4. The levels of temperature, D-xyl absorptivity, Na~+-K~+-ATP, and the indices in the morphological changes in the stomach, spleen, small intestine, liver and cola can all be references in distinguishing the two types of syndromes. The experimental animal models are successfully established under the guidance of the theories of traditional Chinese medicine; all of the process is controlled strictly based on the etiology and pathogenesis of traditional Chinese medicine.Conclusion: To modify and develop the syndrome differentiation of Three-Yang and Three-Yin discussed in the classic of Treatise on Febrile Disease.
