    ObjectiveTo investigate the protective effect and mechanism of Xingnaojing(Traditional Chinese Medicine) injection on brain injury in rats.MethodsSixty-three healthy adult male SD rats were randomly divided into 3 groups (n = 21): sham operation group, model group, xingnaojing group. The model of traumatic brain injury model group and Xingnaojing group used the free fall impact injury method, the sham operation group underwent craniotomy, did not cause brain damage. Xingnaojing group in rats after 10 min by tail vein injection Xingnaojing injection 10 ml/(kg x d), model group and sham operation group were intravenously injected with 0.9% sodium chloride solution, three groups were administered continuously for 7 days. At administration of the seventh days compared the S-100B protein in the serum and neuro specific enolase (NSE) level, the water content of brain tissue, serum superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione peroxidase (GSH-Px) content, and neurological function of rats among groups.ResultsCompared with the sham operation group, the nerve defect, brain water content, MDA, S100B protein and NSE levels were obvigusly increased in Xingnaojing group and model group; SOD, GSH-Px content decreased significantly; In Xingnaojing group nerve impairment and brain moisture were significantly lower than those of model group, the serum MDA, S-100B protein and NSE levels were significantly lower than those in the model group, the SOD, GSH-Px activity was significantly higher than that in the model group.ConclusionXingnaojing injection has protective effects on rat brain injury, and its mechanism may be related to reduce brain edema after traumatic brain injury and inhibit the reaction of oxygen free radical, protect nerve cells.
