ABSTRACT
Zixue was first recorded in detail in Qianjin Yifang, and practitioners of later generations renamed it as Zixuesan and Zixuedan, which is the representative prescription of antipyretic preparations and has high clinical application and research value. At present, there have been many studies on the pharmacological effect and clinical application of Zixue, but the medical books of the past dynasties have slightly different records on Zixue, which has brought some difficulties to the reasonable clinical application and research of this prescription. In addition to the introduction of Zixuesan, which is different from the ancient recipe, the researchers have questions about which development method can reasonably inherit and develop the classical preparation. The authors intend to summarize the historical evolution of "formula" and "preparation" of Zixue, in order to clarify its historical context, which can provide a reference for the modern research and development of this formula, and provide a new ideas for the in-depth exploration of other classic preparations.
ABSTRACT
This study was aimed to analyze medication experiences of Professor Sun Zixue in the treatment of asthenospermia. A total of 286 asthenospermia cases treated by Prof. Sun Zixue were collected. Frequency and index clustering analysis method were used in the processing of patient data. The results showed that the using frequency of 37 types of drugs is more than 10%. And the clustering analysis classified drugs into seven cat-egories , which were the kidney essence tonification , kidney-yang tonification , qi tonification , blood nourish-ment , heat-toxin reducing , heat-dampness reducing , blood-activation and collateral-regulation. It was conclud-ed that based on Prof. Sunˊs syndrome differentiation , the treatment of asthenospermia can be from the combi-nation of kidney tonification , qi tonification and blood nourishment , or the combination of heat-dampness re-ducing and blood-activation and stasis-removing , or the combination of kidney tonification and collateral-regu-lation. The commonly used drugs are 38 types from seven categories .
