Clinical analysis of central venous catheter-related infections in patients in the emergency ICU.

Background: Catheter-related infection (CRI) of the central vein is a common cause of nosocomial infection. This study was undertaken to investigate the pathogen culturing and risk factors of CRI in emergency intensive care unit (EICU) in order to provide the beneficial reference.

Methods: From January 2008 to December 2010, a total of 1 363 patients were subjected to catheterization.

Rosiglitazone enhances the proliferation of neural progenitor cells and inhibits inflammation response after spinal cord injury.

It has been previously shown that peroxisome proliferators-activated receptor gamma (PPAR-γ) is beneficial for nervous system injury. In present study, we examined the effect of rosiglitazone, a PPAR-γ agonist, on spinal cord injury (SCI) in rats. SCI was induced by dropping a 10g weight rod at a height of 25mm.

[Arsenite removal performance by modified GAC].

Two kinds of Fe-Mn oxide impregnated GAC (FM-GAC-1, FM-GAC-2) were prepared and their arsenite removal performance were studied. The adsorption isotherm and reaction kinetic models of arsenite on the two kinds of modified GAC and influence of solution pH, temperature and co-exist anions were investigated in the study. The results showed FM-GAC-1 and FM-GAC-2 can adsorb arsenite effectively, the adsorption capacities were 32.
