Objective To investigate the effect of Omi/Htr A2 mediated mitochondrial signaling pathway in neuronal apoptosis after acute traumatic brain injury. Methods Brain tissue samples were collected during craniotomy from 100 patients with cerebral contusion and laceration(trauma group), and normal brain tissue samples were collected from 100 patients with intracerebral hemorrhage(control group). Flow cytometry was applied to determine apoptotic neuronal cells, Western-blotting was performed to test expressions o...
