摘要
目的探讨丁苯酞(NBP)注射液对大鼠局灶性脑缺血再灌注损伤的神经保护作用及可能机制。方法将雄性Sprague-Dawley(SD)大鼠75只随机分为假手术组(Sham组)、脑缺血组(IR组)、NBP高剂量后处理组(高剂量组)、NBP中剂量后处理组(中剂量组)和NBP低剂量后处理组(低剂量组),每组15只。采用改良线栓法制备大鼠大脑中动脉局灶性脑缺血再灌注(MACO)模型。缺血2 h后再灌注24 h,行神经功能缺损评分及脑梗死体积测定。原位末端标记法(TUNEL)检测脑梗死灶周围组织神经细胞凋亡;免疫组织化学染色法检测沉默信息调节因子2相关酶1(SIRT1)、过氧化物酶体增殖活化受体γ共激活因子-1α(PGC-1α)阳性细胞;实时荧光定量PCR法检测SIRT1、PGC-1αmRNA的表达。结果 Sham组未见神经功能缺损症状及脑梗死体积。与Sham组比较,IR组、3个剂量的NBP后处理组凋亡细胞数增多,SIRT1、PGC-1α阳性细胞数及mRNA的表达增多(P均<0.05)。与IR组比较,3个剂量的NBP后处理组神经功能评分降低,脑梗死体积、凋亡细胞数减少,SIRT1、PGC-1α阳性细胞数及mRNA的表达增多(P均<0.05)。不同剂量NBP后处理组间比较,高剂量组神经功能评分最低,脑梗死体积、凋亡细胞数最少,SIRT1、PGC-1α阳性细胞数及mRNA表达最多(P<0.05)。结论 NBP能减轻大鼠脑缺血再灌注损伤,发挥脑保护作用,其机制可能与SIRT1、PGC-1α表达上调有关。
