Research progress on effective components of Chinese materia medica in regulating autophagy / 中国中药杂志

Autophagy is a highly conservative and multi-component activated energy metabolism and self-renewal mechanism, which plays a crucial regulatory role in maintaining the normal physiological state of cells and is involved in various pathological processes. In recent years, the mechanism study has made great progress in regulating autophagy with effective components of Chinese materia medica(CMM),which are reported to prevent and treat cancers, neurodegenerative diseases, cardiovascular diseases and metabolic and immune-related diseases. This review outlines the molecular regulation mechanisms of cell autophagy with CMM components in controlling the above-mentioned diseases. There are many relevant reports on the regulatory mechanisms of autophagy in tumor and cardiovascular cells with CMM monomers. The main chemical structural types are alkaloids, saponins, polyphenols, flavonoids and terpenes. And m-TOR pathway is the main mechanism relating to the regulatory mechanisms of autophagy with CMM. Therefore, the regulatory mec-hanisms of cell autophagy become a new research targeting strategy of therapies with CMM. This review provides evidences for the effectiveness and scientificity of CMM in regulating autophagy, in the expectation of providing references for the in-depth studies of CMM in the field of autophagy and the development of natural autophagy regulators.

Review on factors influencing separation and purification of Chinese materia medica components by macroporous adsorption resin / 中草药

In recent years, macroporous adsorption resin has been widely used in the purification and separation of natural medicine and effective components of Chinese materia medica, the purification of compound Chinese medicine preparations, the removal of harmful impurities due to the advantages of stable physical and chemical properties, high selectivity, strong adsorption capacity and easy elution, recyclable use and regeneration treatment, economic and environmental protection, convenient preparation molding and so on. By summarizing the preparation, properties, classification and working principle of macroporous adsorption resin, the influencing factors and purification process of Chinese materia medica components were reviewed. The purpose of this paper is to explore the important factors affecting the purification of Chinese materia medica components by macroporous adsorption resin, and provide reference for improving the purification effect of Chinese materia medica components.
