[The clinical value of three-dimensional computed tomographic angiography in embolization of acutely ruptured intracranial aneurysms with Guglielmi detachable coil].
To evaluate the clinical value of three-dimensional computed tomographic angiography (3D-CTA) in embolization of ruptured intracranial aneurysms with Guglielmi detachable coil (GDC). ⋯ 3D-CTA discloses the existence of intracranial aneurysms early, establishes the indications of embolization prior to the catheter angiography, determines the side of insertion of guiding catheters, helps choose the appropriate coil size, and may become a routine diagnostic modality.

[Evaluation of bone architecture and biomechanic properties by peripheral quantitative computed tomography in rats].
To evaluate the value of peripheral quantitative computed tomography (pQCT) in measuring bone architecture and biomechanic properties. ⋯ The geometric, densitometric and mechanical properties in cortical and trabecular bones of rat can be well described by pQCT.

[A low level of TNF-mediates hemorrhage-induced acute lung injury via p55 TNF receptor].
To examine the temporal relationship of pulmonary TNF-alpha production to acute lung injury (ALI) during hemorrhagic shock (HS). ⋯ A low level of pulmonary TNF-alpha is sufficient to mediate HS-induced acute lung injury and that the p55 TNF-alpha receptor plays a dominant role in regulating the pulmonary inflammatory response to HS. The results suggest that anti-TNF-alpha strategies for the control of the pulmonary inflammatory response to HS can be directed toward antagonizing the p55 TNF-alpha receptor.

[Effect of intraischemic mild hypothermia on interleukin-1beta and monocyte chemoattractant protein-1 contents in ischemic core of rat cortex after transient focal cerebral ischemia].
To investigate the effect of intraischemic mild hypothermia on the protein levels of interleukin (IL)-1beta and monocyte chemoattractant protein (MCP)-1 in the ischemic core of rat cortex after transient focal cerebralischemia. ⋯ Mild hypothermia reduces the level of MCP-1 in the cortex after cerebral ischemia/reperfusion which may be one of the important mechanisms of the neuroprotective effects of mild hypothermia.

[Continuous surveillance of antimicrobial resistance among nosocomial gram-negative bacilli from intensive care units in China].
To investigate the change of antimicrobial resistance among nosocomial gram-negative bacilli, especially those of Enterobacteriaceae isolated from intensive care units from 1994 to 2001 in China. ⋯ Imipenem remains highly active against Enterobacteriaceae, but the activities of other antibiotics have decreased in recent years.
