[Research progress on Piperis Longi Fructus and predictive analysis of its quality markers].

Piperis Longi Fructus, made from the mature and immature fruit spikes of Piper longum, is a commonly used Mongolian medicine. In recent years, researchers have gradually deepened the research on ethnic medicines and found that Piperis Longi Fructus has significant effects in adjusting blood lipids and anti-cancer. Its new chemical components and pharmacological activities are also constantly updated. Subsequently, the development and application of Piperis Longi Fructus have attracted extensive attention. Thus, it is quite urgent to establish and improve a quality evaluation system for the medicine. On the basis of summarizing the chemical components and pharmacological effects of Piperis Longi Fructus and understanding the new concept of quality marker(Q-marker), the components which can be used as its Q-markers were analyzed from the aspects of the genetic relationship, traditional medicinal effects and properties, rules of compounding and compatibility, absorbed components and testability. The research can provide reference for the establishment of a quality evaluation system for Piperis Longi Fructus.

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.
