Proteomics and its application to determine mechanism of action of traditional Chinese medicine / 中国中药杂志

There is no doubt that the traditional Chinese medicine(TCM) is effective, practical and scientific after it was used for thousands of years. However, the mechanisms of action of many TCM are still unclear because of their multi-component, multi-target and multi-level features, which hinder the modernization and internationalization of the TCM. Proteomics is to analyze the composition and activity of intracellular proteins which are changing dynamically from a holistic perspective. It is consistent with the holistic and dynamic views of the TCM and brings about the hope of clarifying the mechanism of action of the TCM. In recent years, great progress has been made in the application of proteomics to determine the mechanism of the TCM. This article introduced the core technologies of proteomics and systematically summarized the applications of proteomics in the study of the mechanism of the Chinese medicinal formulae, single Chinese medicine and monomeric compounds from the TCM to provide innovative ideas and methods for reference.

Nrf2-NF-κB pathway axes, epigenetic regulation and traditional Chinese medicine (natural medicine) to treat type 2 diabetes / 中国中药杂志

Diabetes mellitus is a characterized by high blood sugar metabolic disease, is a lifelong disease with a high incidence of major hazards. Prevention and treatment of diabetes and its complications has become a serious challenge and arduous task facing the world pharmaceutical researchers. Oxidative stress, Nfr2-NF-κB signaling axis related epigenomic genes have the apparent close relationship with type 2 diabetes,those have become one of the key focus and effective way to explore its pathogenesis, mechanism and drug screening. This paper systematically summarizes the current stage research regulating the key proteins, mRNA about Nrf2-NF-κB axis pathway and epigenomics for treatment of type 2 diabetes and the mechanism of traditional Chinese medicine and natural medicine (component) in the treatment of type 2 diabetes, hoping to provide some innovative research ideas for finding new drugs of the treatment of diabetes from traditional Chinese medicine and natural medicine.

Study on drug properties of components in Euodiae Fructus based on rat stress gastric ulcer model with cold syndrome / 中国中药杂志

<p><b>OBJECTIVE</b>To clarify drug properties of components in Euodiae Fructus.</p><p><b>METHOD</b>The rat cold syndrome model was induced by cold water stress method. The content of neurotransmitters sand hormones such as DA, 5-HT, NE, AChE and 17-OHCS in serum of model rats were taken as the indexes to evaluate drug properties of components in Euodiae Fructus.</p><p><b>RESULT</b>Euodiae Fructus and its components could correct or relief the content of energy metabolism and substance metabolism-related neurotransmitters sand hormones in serum of model rats with water-stressed cold syndrome.</p><p><b>CONCLUSION</b>Euodiae Fructus and its components are proved to show hot property.</p>

A new megastigmane glycoside from the aerial parts of Cirsium setosum / 中国天然药物

AIM@#To study the chemical constituents of the aerial parts of Cirsium setosum (Willd.) MB..@*METHODS@#The chemical constituents were isolated and purified by various chromatographic techniques. Their structures were determined on the basis of physical properties and spectroscopic data.@*RESULTS@#A new megastigmane glycoside and six known compounds were obtained and identified as (7E, 9R)-9-hydroxy-5, 7-megastigmadien-4-one-9-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyanoside (1), (6R, 7E, 9R)-9-hydroxy-4, 7-megastigmadien-3-one-9-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (2), urolignoside (3), 4, 9, 9'-trihydroxy-3, 3'-dimethoxy-8-O-4$\prime $-neolignan-7-O-β-D-glucopyranoside (4), citroside A (5), salidrosidin (6), and adenosine (7).@*CONCLUSION@#Compound 1 is a new megastigmane glycoside, named as Xiaojiglycoside A.
