ABSTRACT
The processing of Traditional Chinese Medicine requires the appropriate parameters, while the specific chemical markers are still absent to obtain the optimized processing. In this study, we used vinegar-baked Euphorbia kansui as a case to dissect the chemical markers for the baking process using untargeted metabolomics. The robust chemical markers were selected based on the three rules, correlation, significant difference, and controllability. All the differential features were categorized based on their mass defects. After the differential analysis, 310 differential compounds were screened out and could be mainly divided into six categories: diacylglycerols and triacylglycerols demonstrated increasing trends with the baking time in the discriminant model, while ingenane-type diterpenes, jatrophane-type diterpenes, fatty acid esters, and fatty acids had decreasing trends. It was unexpected to find that the diterpenes did not correlate with the baking time. Only very few compounds meet the three rules. They were validated with a high-performance liquid chromatography method. Finally, only 13-Hydroxy-9,11-octadecadienoic acid and its isomer 9-Hydroxy-10,12-octadecadienoic acid could be used further to differentiate the commercial vinegar-baked Euphorbia kansui. It would be of interest to evaluate whether these two compounds could be utilized as markers to control more processing methods in future studies.

The integration of habitat processing and processing of Chinese medicinal decoction pieces(hereinafter referred to as "integration") has changed the traditional processing mode and can ensure the quality of Chinese medicinal decoction pieces from the source. This paper introduced the background of integration from the connotation and denotation of integration, relevant policies and regulations, and variety development. The present situation of integration was analyzed from the existing problems and current research progress, and the development suggestions were proposed. It is considered that although the integration is in line with the development trend of the industry with the advantages of improving the quality and standardizing the management of decoction pieces, there are still some problems, such as the lack of variety selection principles and production technical specifications, imperfect quality control stan-dards in the production process, and inadequate integration of standards and supervision. Therefore, it is suggested to determine the integrated variety selection principles and variety range as soon as possible, establish relevant technical specifications, improve quality control standards in the production process, and strengthen policy guidance and supervision to promote the healthy and orderly development of integration.

Chinese medicinal decoction pieces were the mainly form for traditional Chinese medicine (TCM) treatment,which means TCM prescription drugs.Any processed (heated or unheated) pieces are known as prepared pieces,which include both raw and cooked pieces.Based on differences of the clinical application of processed pieces,this paper summarized three traditional processing theories,such as the raw and prepared effect difference theory,processing accessories action theory,and pharmaceutical theory.The key points were focused on how different processing methods affect the properties of Chinese herbs,such as four natures and five flavors,floating and sinking,attributive channel,tonifying or purging action,and the toxicity.Based on changes of pharmacodynamic substance base and pharmacological action before and after processing,the action mechanism of processing in changes of Chinese medicinal properties was explained.
ABSTRACT
OBJECTIVE:To promote the information management of Chinese medicinal decoction piece.METHODS:Information management modes in every part of the management of Chinese medicinal decoction piece were discussed basing on network structure and operating environment of hospital drug management system.RESULTS&CONCLUSION:Database for rational use of Chinese medicinal decoction pieces has been established to provide links of network operation platform and rational processes,which are beneficial to information management of Chinese medicinal decoction piece.
ABSTRACT
OBJECTIVE:To discuss the importance and prospects of the reforming of the Chinese medicinal decoction pieces. METHODS: The advantages and disadvantages of all kinds of decoction pieces(categorized by particle diameter) in preparation, application and management were analyzed comprehensively. RESULTS & CONCLUSION: Comminuting and extracting are two basic approaches for the current reform of the Chinese medicinal decoction pieces, and the reform of the decoction pieces is mainly aimed at nano-Chinese medicinal decoction pieces.
