Professor Pang He 's Experience In Treating Lower Extremity Venous

[Objective]This research aims to create a Chronic venous insufficiency (CVI) Chinese Medicine (CM) database through recording the prescriptions Professor Pang He used in treatment of CVI patients. Through analysis of the CVI CM database, we hope to establish the main herbs and usage patterns in treatment of CVI, and further propose core herbs for CVI as well as its respective CEAP (Clinical, Etiologic, Anatomic, Pathophysiologic) C classifications.[Methodology]Traditional Chinese Medicine Inheritance Support System Version 2.5 was used to record prescriptions, symptoms and Western Medicine diagnosis for 1022 CVI cases Professor Pang He had treated. A CVI CM database was subsequently established. Herb usage frequencies for CVI and its respective C classifications were analyzed based on the CVI CM database. Herbs with usage frequencies equal to or higher than 70% from each group were selected to form their respective core herbs. Professor Pang He was then consulted for his opinions on disease mechanism, syndrome patterns and herb usage for CVI. The core herbs were then compared with Professor Pang He’s opinions. Suitable syndrome patterns and underlying herb usage patterns from the core herbs were subsequently derived.[Results]Core herbs suitable for CVI, C1 to C6, and the symptoms "lower limb edema (+-)" "lower limb edema (+) " "obvious itchiness" were derived from analysis of the CVI CM database. Through analysis of the core herbs, a CVI core prescription with its herb usage patterns, and "obvious itchiness" core prescription was derived. Through further analysis and discussion, Professor Pang’s CVI disease mechanism, syndrome pattern and herb usage opinions were then proposed.[Conclusion]Through analysis of the CVI CM database, we were able to propose the main herbs and its usage patterns in Professor Pang He’s treatment of CVI patients. Core herbs were derived for CVI and its respective C classifications, and Professor Pang’s opinions on CVI disease mechanism, syndrome patterns and herb usage patterns were consolidated. Although statistical analysis of herb frequencies using a large sample was able to conclude the main herbs Prof Pang used, several segments of Professor Pang’s opinions were only reflected in selected cases. These segments were unable to be surface under the large sample, and only a general pattern can be derived from this analysis.
