摘要 目的研究重组人促红细胞生成素(rhEPO)对急性脑缺血大鼠脑组织中核因子E2相关性因子2(Nrf2)及血红素加氧酶(HO-1)表达的影响,探讨rhEPO的抗氧化作用机制。方法随机将36只雄性SD大鼠分为假手术组、缺血组和rhEPO治疗组。采用线栓法制作大鼠永久性局灶性脑缺血(pMCAO)模型。rhEPO治疗组在缺血2h后腹腔注射rhEPO 5 000IU/kg,模型组和假手术组在等时间点给予等量的生理盐水。TTC(2,3,5-氯化三苯基四氮唑)法测量脑梗死体积,免疫组化方法测定脑组织中Nrf2及HO-1的表达。结果 rhEPO治疗组与缺血组相比,脑梗死体积减小,各组脑组织中Nrf2及HO-1的表达量按假手术组、缺血组、rhEPO治疗组依次增高,各组间差异均具有统计学意义(P<0.01)。结论急性脑缺血后,脑组织中Keap1-Nrf2/ARE抗氧化系统被激活,rhEPO可能通过激活该氧化系统而发挥脑保护作用。
