Case ReportsUncorrected traumatic coagulopathy is associated with severe brain swelling during decompressive surgery to evacuate a supratentorial intradural mass lesion in patients with traumatic brain injury.
This study investigated the relationship between traumatic coagulopathy and severe brain swelling (SBS) during decompressive surgery to evacuate a supratentorial intradural mass lesion in patients with traumatic brain injury (TBI). ⋯ Intraoperative SBS is not a rare event during decompressive surgery to evacuate a supratentorial intradural mass lesion in patients with TBI. Such surgery should be cautiously considered and performed given the existence of uncorrected traumatic coagulopathy, which is associated with an increased risk of intraoperative SBS.

Tetrandrine ameliorates cognitive impairment via inhibiting astrocyte-derived S100B activation in a rat model of chronic cerebral hypoperfusion.
To investigate the effects of tetrandrine (Tet) on cognitive impairment induced by chronic cerebral hypoperfusion and its potential anti-inflammatory mechanism by modulating the expression of S100B, interleukin-1 beta (IL-1 beta), tumor necrosis factor-alpha (TNF-alpha), and inducible nitric oxide synthase (iNOS). ⋯ Our results found that Tet could improve cognitive impairment in the chronic cerebral hypoperfusion rats. Tetrandrine may be a novel and promising candidate for future treatment and/or prevention of chronic cerebral hypoperfusion via inhibiting S100B activation and decreasing the expression of IL-1 beta, TNF-alpha, and iNOS in the hippocampal CA1 region.
