Abstract: |
Objective.. To investigate the application of entropy partition method (EPM) for studying the diagnostic criteria of Traditional Chinese Medicine (TCM) syndrome. Methods.. A clinical epidemiological survey was conducted in 400 patients with vascular endothelial dysfunction and the EPM was adopted to extract the TCM syndrome elements of "stagnancy of collateral-Qi in a deficiency condition", the correlation degree between each symptom of "stagnancy of collateral-Qi in a deficiency condition" was calculated and the diagnostic threshold of vascular endothelial dysfunction was established. The sensitivity, specificity and accuracy of the EPM-associated diagnostic criteria were assessed by comparing with those of clinical epidemiology. Results: The diagnostic criteria of "stagnancy of collateral-Qi in a deficiency condition" in vascular endothelial dysfunction established with EPM had a satisfactory diagnostic efficiency. Conclusion: EPM for complex system is suitable for studying the diagnostic criteria of TCM syndrome. EPM is a scientific and strict method and has great value in clinical practice.[著者文摘] |
