Application of traditional Chinese medicine theory in modern traditional Chinese medicine nano-preparation: taking tumor treatment as an example / 中国中药杂志

With Zang-Fu organs, meridians, Qi and blood, and body fluid as the physiological and pathological basis, traditional Chinese medicine(TCM) theory is guided by the holistic concept and characterized by syndrome differentiation. It has made significant contributions to human health maintenance and disease prevention. Modern TCM preparation is developed on the basis of inheriting and developing TCM preparations using modern science and technology under the guidance of TCM theory. At present, the incidence and mortality of common tumors are increasing. TCM has rich clinical experience in the treatment of tumors. However, in the current stage, some TCM preparations have a tendency to deviate from the guidance of TCM theory. With the modernization of TCM, it is worth considering how TCM theory guides modern TCM preparations. Taking tumor treatment as an example, this paper introduced the development of TCM nano-preparation under the influence of modern nanotechnology, summarized the research on the development of modern TCM nano-preparation from the aspects of TCM holistic concept, TCM treatment principles, and TCM theory application, and discussed the application prospect of TCM nano-preparation in overall therapy, drug pairing, carrier selection, and targeted substance selection under the guidance of TCM theory. This paper provides new references for further developing the combination of tradition and modernization of TCM nano-preparation.

Study on benchmark preparation technology of boiled and powdered classical prescriptions by taking Houpo Wenzhong Decoction as an example / 中国中药杂志

In recent years,the development and application of classical famous prescriptions have attracted much attention. However,the differences between ancient and modern conditions lead to difficulties in carrying out practical work. In this paper,with Houpu Wenzhong Decoction as an example,the key technologies of boiling granularity,water addition,boiling time and sample pretreatment methods were investigated on the basis of sufficient literature research. The experimental results showed that there was no significant difference in the concentration of index components between those with different granularity( 2 mm and 3-5 mm) and different decocting time( 30 min and 60 min),but the extraction rate of index components was relatively high when the granularity of powder was 2 mm and decocting time was 30 min. With the increase of water content,the concentration of index components and the extraction rate were increased in varying degrees. A certain proportion of methanol aqueous solution was used as the resolvent before content determination of the reference sample of Houpu Wenzhong Decoction,which could take into account both the spectral information of water-soluble components and fat-soluble components in the prescription,and help to display the overall information of the prescription' s chemical components more comprehensively. At the same time,the boiling and dispersing classical prescriptions in the Catalogue of Ancient Classical Prescriptions( the first batch) were collected and summarized in this study; the key influencing factors of decocting process were analyzed from different angles,and preliminary research suggestions were put forward,so as to provide a certain direction and reference for the establishment of quality standard of Houpu Wenzhong Decoction,as well as for the development,research and clinical application of boiling and dispersing classical prescriptions.
