[Proteomics and its application to determine mechanism of action of traditional Chinese medicine].

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.

The Mechanisms of Traditional Chinese Medicine Underlying the Prevention and Treatment of Parkinson's Disease.

Parkinson's disease (PD), characterized with bradykinesia, static tremor, rigidity and disturbances in balance, is the second most common neurodegenerative disorder. Along with the largely aging population in the world, the incidence is increasing year by year, which imposes the negative impacts on patients, their families and the whole society. Traditional Chinese medicine (TCM) has a positive prospect for the prevention and cure of PD due to its advantages of less side effects and multi-target effects.

[Nrf2-NF-κB pathway axes, epigenetic regulation and traditional Chinese medicine (natural medicine) to treat type 2 diabetes].

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.

UHPLC-MS/MS Determination, Pharmacokinetic, and Bioavailability Study of Taxifolin in Rat Plasma after Oral Administration of its Nanodispersion.

A rapid and sensitive LC-MS/MS method based on the Triple Quad system has been developed and validated for the determination and pharmacokinetics of taxifolin and its nanodispersion in rat plasma. Taxifolin plasma samples along with butylparaben (internal standard) were pre-treated by liquid-liquid extraction with ethyl acetate, and then separated on a SB-C18 RRHD column (150 mm × 2.1 mm × 1.

[Study on drug properties of components in Euodiae Fructus based on rat stress gastric ulcer model with cold syndrome].

Objective: To clarify drug properties of components in Euodiae Fructus.

Method: 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.

A new megastigmane glycoside from the aerial parts of Cirsium setosum.

Aim: To study the chemical constituents of the aerial parts of Cirsium setosum (Willd.) MB..

Monoterpenoids from Acanthopanax sessiliflorus fruits.

Three new acyclic monoterpenoids named (2E)-3,7-dimethylocta-2,6-dienoate-6-O-α-L-arabinopyranosyl-(1→6)-β-D-glucopyranoside (1), (3Z,6E)-3,7-dimethyl-3,6-octadiene-1,2,8-triol (2) and (6E)-7-methyl-3-methylene-6-octene-1,2,8-triol (3) were isolated from Acanthopanax sessiliflorus fruits, along with three known monoterpenoid compounds. The structures of the new compounds were determined by means of extensive spectroscopic analysis (1D, 2D NMR and HRESIMS) and chemical methods.

[Study on chemical constituents of Herba Cirsii].

Objective: To study the chemical constituents from the aerial part of Herba Cirsii.

Methods: Compounds were isolated by various chromatographic techniques and identified by spectral data.

Results: Eight compounds were obtained.
