Effect of Chinese Medicine on Diabetic Wound Based on Nrf2 Signaling Pathway： A Review / 中国实验方剂学杂志

Diabetic wound healing disorder，one of the common chronic complications of diabetes，seriously influences the quality of life of patients and even causes disability and death，bringing a heavy burden to the society. Chinese medicine，a unique and precious resource in China，is safe with definite effect. Oxidative stress plays an important role in the occurrence and development of diabetic wound and the disturbance of antioxidant defense mechanism is among the causes of the lingering diabetic wound. As a vital transcription factor for intracellular redox homeostasis，nuclear factor erythroid 2-related factor 2 （Nrf2） regulates oxidative/heterogenous stress and reduces inflammatory responses. Although it is unnecessary for common wound healing，it is of great importance for diabetic wound healing. Many Chinese medicinals and the active ingredients have been found to enhance diabetic wound healing by mechanisms related to activation of the Nrf2 signaling pathway. Targeted activation of Nrf2 by Chinese medicine can alleviate oxidative stress，inflammatory response，and apoptosis in diabetic wound，thereby delaying further exacerbation of symptoms. Therefore，Nrf2 is regarded as a potential target for drugs to boost diabetic wound healing. This study summarizes the relationship between the Nrf2 signaling pathway and diabetic wound and analyzes the mode of action and possible mechanisms of Chinese medicine and its active ingredients in promoting diabetic wound healing through modulating the Nrf2 pathway，which is expected to serve as a reference for developing drugs for diabetic wound based on this pathway.

Regulatory effect of traditional Chinese medicine on intestinal microbiota / 中国中药杂志

As a large micro-ecosystem in the human body,the intestinal microbiota is closely associated with the occurrence of many diseases.The clinical investigations and animal experiments have showed that traditional Chinese medicine(TCM) could maintain the balance of the intestinal micro-ecological system.This review summarized the research methods and literatures on the regulation effects of TCM,including different effective ingredients,extracts and Chinese herbal formulae,on intestinal microflora in recent five years,in order to provide a reference for the further research and development of TCM.

Research advance in metabolism of effective ingredients from traditional Chinese medicines by probiotics / 中国中药杂志

The pharmacological activity of active ingredients from Chinese medicine depends greatly on the microecological environment of probiotics in the human body. After effective ingredients from traditional Chinese medicines are metabolized or biotransformed by probiotics, their metabolites can increase pharmacological activity, and can be absorbed more easily to improve the bioavailability. Therefore, the combination of Chinese medicines with probiotics is the innovation point in R&D of functional food and Chinese medicines, and also a new thinking for the modernization of Chinese medicine.This review summarizes and analyses the research progress on metabolism effects of gut microbiota on Chinese medicines components, the regulating effect of effective ingredients from Chinese medicine on intestinal probiotics, the application status of probiotics in traditional Chinese medicines, and the main problems and prospects in the research and development of Chinese medicines products with probiotic, aiming to provide theoretical guidance and practical value for the fermentation engineering of Chinese herbal medicine.

Interaction of effective ingredients from traditional Chinese medicines with intestinal microbiota / 中国中药杂志

A large number and wide varieties of microorganisms colonize in the human gastrointestinal tract. They construct an intestinal microecological system in the intestinal environment. The intestinal symbiotic flora regulates a series of life actions, including digestion and absorption of nutrient, immune response, biological antagonism, and is closely associated with the occurrence and development of many diseases. Therefore, it is greatly essential for the host's health status to maintain the equilibrium of intestinal microecological environment. After effective compositions of traditional Chinese medicines are metabolized or biotransformed by human intestinal bacteria, their metabolites can be absorbed more easily, and can even decrease or increase toxicity and then exhibit significant different biological effects. Meanwhile, traditional Chinese medicines can also regulate the composition of the intestinal flora and protect the function of intestinal mucosal barrier to restore the homeostasis of intestinal microecology. The relevant literatures in recent 15 years about the interactive relationship between traditional Chinese medicines and gut microbiota have been collected in this review, in order to study the classification of gut microflora, the relationship between intestinal dysbacteriosis and diseases, the important roles of gut microflora in intestinal bacterial metabolism in effective ingredients of traditional Chinese medicines and bioactivities, as well as the modulation effects of Chinese medicine on intestinal dysbacteriosis. In addition, it also makes a future prospect for the research strategies to study the mechanism of action of traditional Chinese medicines based on multi-omics techniques.
