Review of traditional Chinese medicines in ameliorating neuropsychiatric diseases by improving the levels of monoamine neurotransmitters via gut microbiota regulation / 中国中药杂志

The degeneration of monoaminergic system and the reduction of monoamine neurotransmitters(MNTs) are associated with the occurrence of a variety of neuropsychiatric diseases, becoming the key indicators for clinical diagnosis and treatment. Recent studies suggested gut microbiota could influence the occurrence, development, and treatment of neuropsychiatric diseases by directly or indirectly regulating the synthesis and metabolism of MNTs. Rich clinical experience has been accumulated in the amelioration and treatment of neuropsychiatric diseases by traditional Chinese medicines. The traditional oral administration method demonstrates obvious advantages in regulating gut microbiota. It provides a new idea for explaining the pharmacodynamic material basis and mechanism of traditional Chinese medicines in ameliorating neuropsychiatric disease by improving the levels of MNTs via gut microbiota regulation. Focusing on three common neuropsychiatric diseases including Alzheimer's disease, Parkinson's disease, and major depression, we summarized the pathways of gut microbiota in regulating the levels of MNTs and the paradigms of traditional Chinese medicines in ameliorating neuropsychiatric diseases via the "bacteria-gut-brain axis", aiming to provide ideas for the development of drugs and treatment schemes.

Research Progress on Chemical Constituents and Pharmacological Effects of Piperis Fructus / 中国实验方剂学杂志

Piperis Fructus is the dried nearly ripe or ripe fruit of Piperaceae, which is an important spice material and a traditional Chinese medicine (TCM), it is widely used in the world. It is recorded to possess the efficacy of warming spleen and stomach for dispelling cold, depressing Qi and dissolving phlegm. Piperis Fructus mainly contains amide alkaloids with piperine as the main ingredient and volatile oil dominated by monoterpenoids and sesquiterpenoids, which have a wide range of biological activities, such as anti-cancer, anti-oxidation, anti-inflammatory, etc. By referring to relevant papers at home and abroad, the researches on chemical compositions from different parts and pharmacological effects of Piperis Fructus in recent 5 years were summarized and analyzed. It was found that Piperis Fructus has great potential for drug development as a TCM with homology of medicine and food, which can provide a reference for further research and comprehensive utilization of Piperis Fructus.
