These factors have all greatly limited its clinical use for treating postoperative pain. Meanwhile, non-steroidal anti-inflammatory drugs （NSAIDs） play an increasingly important role in postoperative analgesia. Some studies suggest that NSAIDS may be neural protective in cerebral ischemic conditions.展开更多

But its function under cerebral ischemic conditions is unclear. This study was designed to evaluate the neuroprotective efficacy of emulsified flurbiprofen axetil （FA, COX inhibitor） and its therapeutic time window in a model of transient middle cerebral artery occlusion （MCAO） in rats. Methods Forty-eight male SD rats were randomly assigned into six groups （n=8 in each group）; three FA groups, vehicle, sham and ischemia/reperfusion （I/R） groups. Three doses of FA （5, 10 or 20 mg/kg, intravenous infusion） were administered just after cerebral ischemia/reperfusion （I/R）. The degree of neurological outcome was measured by the neurologic deficit score （NDS） at 24, 48 and 72 hours after I/R. Mean brain infarct volume percentage （MBIVP） was determined with 2,3,5-triphenyltetrazolium chloride （TTC） staining at 72 hours after I/R. In three other groups （n=8 in each group）, the selected dosage of 10 mg/kg was administrated intravenously at 6, 12 and 24 hours after I/R. Results The three different doses of FA improved NDS at 24, 48 and 72 hours after I/R and significantly reduced MBIVP. However, the degree of MBIVP in the FA 20 mg/kg group differed from that in FA 10 mg/kg group. Of interest is the finding that the neuroprotective effect conferred by 10 mg/kg of FA was also observed when treatment was delayed until 12-24 hours after ischemia reperfusion. Conclusion COX inhibitor FA is a promising therapeutic strategy for cerebral ischemia and its therapeutic time window could last for 12-24 hours after cerebral ischemia reperfusion, which would help in lessening the initial ischemic brain damage.展开更多

This study aimed to investigate whether FA could promote a neuroprotective effect by activation of peroxisome proliferator-activated receptor-y （PPAR-y） after focal cerebral ischemia in rats. Methods Totally 48 male Sprague-Dawley （SD） rats were randomly assigned into six groups （n=8 in each group）： animals in group ischemia/reperfusion （I/R） only received 120-minute transient middle cerebral artery occlusion （tMCAO）; animals in group I/R ＋FA were administered FA （10 mg/kg） by caudal vein just after 120-minute tMCAO; animals in group I/R ＋FA＋GW9662 were administered GW9662 （a PPAR-Y inhibitor, 1 mg/kg） intraperitoneally 30 minutes before cerebral ischemia onset and FA （10 mg/kg） by caudal vein just after 120-minute tMCAO; animals in group I/R ＋GW9662 were administered GW9662 （1 mg/kg） intraperitoneally 30 minutes before cerebral ischemia onset; animals in group I/R ＋DMSO were administered 3% DMSO （vehicle of GW9662, 1 ml/kg） intraperitoneally 30 minutes before cerebral ischemia onset; animals in sham group experienced the identical surgery apart from the insertion of the nylon filament. The neurologic deficit score （NDS） were performed at 72 hours after reperfusion, and then mean brain infarct volume percentage （MBIVP） was determined with 2,3,5-triphenyltetrazolium chloride （TTC） 10 g/L staining. Results NDS was significantly increased in group I/R＋FA （12.0 （10.0-15.0））, group I/R＋FA＋GW9662 （10.0 （8.0-12.0））, and in group I/R＋FA＋DMSO （12.0 （9.0-14.0）） at 72 hours after reperfusion compared with those in group I/R （7.5 （6.0-10.0））. NDS was conspicuously different between group I/R＋FA （12.0 （10.0-15.0）） and group I/R＋FA＋GW9662 （10.0 （8.0-12.0））. MBIVP in group I/R （（45.82±8.83）%） was significantly greater than that in group I/R＋FA （（23.52±9.90）%）, group I/R＋FA＋GW9662 （（33.17±7.15）%）; MBIVP in group I/R＋FA （（23.52±9.90）%） was significantly smaller than that in group I/R＋FA＋GW9662 （（33.17±7.15）%）. Conclusions FA confers the neuroprotective effect on tMCAO in rats and the selective PPAR-Y antagonist GW9662 attenuates the effect of FA. FA could promote a neuroprotective effect by, or in part, activation of PPAR-y after focal cerebral ischemia in rats.展开更多
