RESUMEN
Three-dimensional syndrome differentiation is a new mode of syndrome differentiation of exopathic febrile diseases, which is based upon the six meridian syndrome differentiation initiated in Treatise on Cold Attack and defence-qi-nutrient-blood and triple-Jiao syndrome differentiation in the art of warm disease of traditional Chinese medicine. Syndromes appeared in the course of cold pathogenic diseases and warm diseases were differentiated through the survey of clinical cases and observation on syndrome features of exopathic febrile diseases, by applying means of analyzing, reasoning, concluding and deducting, from the stadium, location and nature of the disease. Three-dimensional syndrome differentiation theory explains and generalizes pathological mechanism and types of syndrome on acute exopathic febrile diseases roundly, has constructed theoretical frame and synthetical model of syndrome differentiation of exopathic febrile diseases. However, any new method of syndrome differentiation can not be leave nothing to be desired in the beginning, so it is proposed that we must develop epidemiologic investigation on syndromes of exopathic febrile diseases sequentially, make models of clinical commonly seen syndromes of exopathic febrile diseases and dispose fuzzy phenomenon of syndrome by applying mathematical method. By above measures, three-dimensional syndrome differentiation will be perfected gradually, therefore, it can provide scientific theoretical basis for the treatment of exopathic febrile diseases.
