Abstract:
Objective To investigate the effects of Xiaoyukang capsule on neuroinflammation and neuronal apoptosis after Intracerebral hemorrhage(ICH)in rats by regulating JNK/c-JUN signaling pathway.Methods Adult male SD rats were intrastriatally injected with bacterial collagenase Ⅶ to induce an ICH model and they were randomly divided into blank control group,model control group,Xiaoyukang capsule small dose group,medium dose group,and large dose group.Neurobehavioral tests,body mass measurements,hematoma volume statistics,hematoxylin-eosin(HE)staining,immunofluorescence,deoxynucleotidyl transferase dUTP nick end labeling(TUNEL)staining,enzyme-linked immunosorbent assay(ELISA)and Western Blotting were performed after 3 and 5 days,respectively.Results Compared with the blank control group,the rats in the model control group had severe neurobehavioral defects and weight loss(P＜0.05).The arrangement of neurons in brain tissue was disordered,and there was microglia/macrophages activation,neutrophil infiltration,neuronal apoptosis(P＜0.05).The levels of pro-inflammatory factors TNF-α,IL-1β and the expression of p-JNK,p-c-JUN,Bax,Caspase-3 and Cleaved Caspase-3 protein around hematoma were significantly increased(P＜0.05),while the anti-inflammatory factor IL-10 and anti-apoptotic protein Bcl-2 were decreased(P＜0.05).Compared with the model control group,Xiaoyukang capsule large dose group significantly improved the neurobehavioral function of rats,promoted weight recovery and hematoma absorption(P＜0.05).Reduce the pathological injury of brain tissue,inhibition of microglia/macrophages activation,neutrophil infiltration and neuronal apoptosis(P＜0.05).In addition,the levels of pro-inflammatory factors TNF-α,IL-1β and the expression of p-JNK,p-c-JUN,Bax,Caspase-3,Cleaved Caspase-3 protein around hematoma were significantly decreased(P＜0.05),and the anti-inflammatory factor IL-10 and anti-apoptotic protein Bcl-2 were increased(P＜0.05).Conclusion Xiaoyukang capsule can improve neurobehavioral defects in ICH rats,promote body mass recovery and hematoma absorption,reduce pathological damage of brain tissue,inhibit microglia/macrophage activation and neutrophil infiltration,its mechanism may be achieved by inhibiting JNK/c-JUN-mediated neuroinflammation and neuronal apoptosis.
