Application and Practice of Traditional Chinese Medicine Characteristic Technology Inheritance in Research and Development of Traditional Chinese Medicine Preparations in Medical Institutions

Medical institution preparations play an important role in the development of hospitals,being one of the main forms of traditional Chinese medicine clinical characteristic medication,as well as an important carrier for the inheritance and innovation of traditional Chinese medicine.In recent years,the research and development of traditional Chinese medicine preparations has become a hot spot in the research and development of preparations by medical institutions.Traditional Chinese medicine preparations prepared by traditional processes and their entrusted preparation matters have changed from the current licensing management to filing management.The registration model of traditional Chinese medicine preparations has undergone significant changes,emphasizing more on real data and evaluation results from the objective world,respecting traditional medication experience,and emphasizing the inheritance and innovative development of traditional technological experience.In the process of following teachers in the inheritance project of traditional Chinese medicine,we combined the inheritance of traditional Chinese medicine characteristic technology with the research and development practice of traditional Chinese medicine preparations in medical institutions,and focused on the analysis and discussion of technical problems such as prescription screening,dosage form selection,process route design and clinical observation of traditional Chinese medicine preparations,hoping to provide reference for scholars in the same field of traditional Chinese medicine.

Study on enrichment characteristics of Chinese herbal medicine based on LIBS technology

To improve the accuracy of laser induced breakdown spectroscopy(LIBS) measurement and investigate the enrichment characteristics of trace elements in different parts of Chinese herbal medicine, the original spectral data of different Chinese herbal medicines were preprocessed by combining median absolute deviation(MAD), segmented feature extraction, and wavelet denoising, and the enrichment laws of trace elements in different parts of Chinese herbal medicine were studied based on the calibration free laser induced breakdown spectroscopy(CF-LIBS). For these experimental samples, the contents of K, Ca, Mg, and Fe in chrysanthemum and its roots, stems, and leaves, Iris lactea roots and leaves, Salvia miltiorrhiza and corresponding planting soil were obtained by CF-LIBS. By calculating the element enrichment coefficient, it was found that chrysanthemum had strong enrichment ability of K element, and the enrichment ability of K element was flower > leaf > stem > root. The roots and leaves of Iris lactea showed strong enrichment of Ca and Mg. The enrichment ability for Ca is leaf > root, and for Mg is leaf > root. The enrichment coefficient of Ca and Mg in Salvia miltiorrhiza is higher. The results show that the combination of multiple data preprocessing methods can effectively improve the accuracy of LIBS measurement results. The calculation method of trace element enrichment law in different parts of Chinese herbal medicines provides guidance for the cultivation and fertilization of Chinese herbal medicines and the identification of high-quality Chinese herbal medicines.
