The Use of the Study on TCM Syndrome Diagnostic Criteria According to Entropy-based Partition Method for Complex System

摘要

The research of standardization and normalization of syndromes in Traditional Chinese Medicine (TCM) is the focal and difficult points of TCM, but always fails to make some breakthroughs. In this paper, we try to apply a new analysis method (entropy-based partition method for complex system) to conduct a standardized and normalized study on the TCM syndromes of "deficiency of Yin" syndrome in vascular endothelial dysfunction (ED). Firstly, we carried out a clinical epidemiology survey, chose 400 ED patients, and collected corresponding symptoms information. Then we reached the symptoms combination and the diagnostic threshold of "deficiency of Yin" in ED objectively. Finally, we conducted an examination on this diagnostic criterion through three indexes: sensitivity, specificity and agreement rate. The result shows that the diagnostic criterion of "deficiency of Yin" in ED has a favourable diagnostic effect and the entropy-based partition method for complex system is suitable for study on the diagnostic criterion of syndromes in TCM. It paves a new way for the research of standardization and normalization of syndromes in TCM.
