Dexmedetomidine attenuates inflammation and pancreatic injury in a rat model of experimental severe acute pancreatitis via cholinergic anti-inflammatory pathway.

Background: Excessive inflammatory responses play a critical role in the development of severe acute pancreatitis (SAP), and controlling such inflammation is vital for managing this often fatal disease. Dexmedetomidine has been reported to possess protective properties in inflammatory diseases. Therefore, this study aimed to investigate whether dexmedetomidine pre-treatment exerts an anti-inflammatory effect in rats with SAP induced by sodium taurocholate, and if so, to determine the potential mechanism.

[Dominant species population structure and dynamics of natural secondary forest in Mulan-weichang, China].

To explicate the structure and dynamics of dominant tree populations of the natural se-condary forest in Mulanweichang, the canopy stratum composition, diameter class structure, static life table, survival curve, mortality curve, survival function and the time series prediction were studied. The results showed that there were 9 populations in canopy stratum, with Acer mono, Quercus mongolica, Tilia mandshurica and Betula platyphylla as the dominant populations. The survival curve of A.
