How vitamin E and its derivatives regulate tumour cells via the MAPK signalling pathway?'.

In tumour cells, vitamin E and its derivatives play a critical role in the regulation of multiple signalling pathways through their oxidative and nonoxidative functions. To date, there are 8 known natural vitamin E forms and many kinds of derivatives, among which VES and α-TEA have excellent anticancer activities. The MAPK pathway consists of a complex cascade of proteins that control the proliferation, differentiation and apoptosis of tumour cells.

[Characteristics and Sources of Microbial Aerosols in Urban and Mountainous Areas in Autumn and Winter in Xi'an, China].

To explore the bioaerosol composition characteristics and sources in urban areas and mountains, three sample sites were selected in urban (urban, suburban) and southern mountainous areas in Xi'an, and air, soil, and leaf samples were simultaneously collected. The fungi and bacteria community structures at different sampling sites were analyzed through a high-throughput sequencing method, and their spatio-temporal variations were also examined. Moreover, a source track technique was used to identify the source of microorganisms in the air.

Eighty cases of chronic cholecystitis treated by oral administration of dan an tang.

Objective: To evaluate the clinical therapeutic effects of dan an tang (chronic-cholecystitis-relieving decoction) for chronic cholecystitis.

Methods: The 160 cases of chronic cholecystitis were randomly divided into the treatment group (80 cases) and the control group (80 cases). The former was treated by oral administration of dan an tang (chronic-cholecystitis-Relieving Decoction), and the latter by oral administration of xiao yan li dan Pian (bile-draining anti-inflammatory tablet).
