Abstract:
Objective To investigate the influence of rutin on neuroinflammation in rats with hydraulic shock brain injury by regulating thioredoxin-interacting protein(TXNIP)/NOD-like receptor protein 3(NLRP3)signaling pathway.Methods Rats were randomly separated into model group and sham operation group;the rats in the model group were established by hydraulic impact method.After modeling,they were randomly separated into rutin low(rutin-L,25 mg·kg-1 rutin)and medium(rutin-M,50 mg·kg-1 rutin).D),high(rutin-H,100 mg·kg-1 rutin)dose groups,model group and positive control group(dexamethasone group,0.1 mg·kg-1 dexamethasone),18 animals/group.Each group was intervened with drugs and normal saline once a day,and after continuous intervention for 3 days,the neurological deficit(neurological severity score,NSS)of the rats was scored;the rats were sacrificed by decapitation,the cerebral edema was determined,the brain tissue around the contusion was separated,and the histological changes,inflammatory cytokine indicators-tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β)levels and TXNIP,NLRP3 protein expression levels were measured.Results The rats in the sham operation group had no injury.The integrity of brain tissue in model group was damaged,cell wrinkly nuclei were deeply stained,interstitial edema was accompanied by holes and the TNF-α and IL-1β levels,NSS score,cerebral edema,TXNIP and NLRP3 protein expression levels were all increased compared with those in the sham operation group(P<0.05);after rutin intervention,the pathological injury of rat brain tissue was relieved,and the TNF-α and IL-1β levels,NSS score,cerebral edema,TXNIP,and NLRP3 protein expression levels were all lower than those in the model group(P<0.05),there was no significant difference between the rutin-H group and the dexamethasone group(P>0.05).Conclusion Rutin can inhibit the inflammatory response of hydraulic shock brain injury rats,improve brain tissue injury and edema,which may be related to the inhibition of TXNIP/NLRP3 signaling pathway.
