摘要: 目的:探讨大鼠大脑中动脉阻塞(middle cerebral artery occlusion,MCAO)模型脑组织Th1/Th2细胞平衡与二磷酸腺苷核糖多聚酶-1(Poly(ADP-ribose)polymerase-1,PARP-1)表达是否存在相关性。方法:将健康雄性SD大鼠随机分成正常对照组、假手术组、模型组、PARP-1抑制剂PJ34组,按再灌注不同时间点分为6、12、24、48、72h五个亚组,各组取材前进行神经功能损伤评分,氯化三苯基四氮唑(triphenyltetrazolium chloride,TTC)染色评价脑梗死体积,定量RT-PCR技术检测脑缺血/再灌注损伤病灶中PARP-1 mRNA的表达,Western Blot技术检测PARP-1聚合体蛋白的表达,ELISA技术测定干扰素-γ(interferon-γ,INF-γ)、白介素4(interleukin 4,IL4)水平。结果:与假手术组比,模型组神经功能损伤评分、脑梗死体积、PARP-1表达及炎性反应效应细胞(helper T cell 1,Th1)与辅助性效应细胞(helper T cell 2,Th2)的比值均显著增加(P<0.01);与模型组比,PJ34组梗死体积明显减小(P<0.01),PARP-1表达、Th1/Th2比值均显著降低(P<0.01);Th1/Th2与PARP-1水平呈显著正相关( r=0.984,P<0.05)。结论:MCAO大鼠脑组织Th1 /Th2细胞平衡状态与PARP-1表达存在相关性。

Abstract: Objective: To discuss correlation of Th1/Th2 cells in balance and PARP-1 expression in rat with cerebral ischemia/reperfusion injury. Methods: SD rats were subjected to middle cerebral artery occlusion by suture method, then they were randomly divided into the control group, sham group, model group, PJ34 group, then groups were divided into 5 subgroups according to different reperfusion time points, 6, 12, 24, 48, 72 h, according to the different time points, neurological  deficits of each rat were determined infarct volume was analyzed with 2, 3, 5- triphenyltetrazolium chloride (TTC) staining, the protein and mRNA expression of PARP-1 were detected by real-time quantitative PCR and western blot; the level of INF-γ and IL-4 were determined by ELISA methods. Results: compare to sham group, the neurological  scores, infarct volume, PARP-1 expression and the Th1/Th2 ratio significantly increased at different time points of reperfusion(P<0.01), and reached a peak by 24h. Compare to model group, neurological  scores,  infarct volume, PARP-1 expression and the Th1/Th2 ratio significantly reduced in PJ34 group(P<0.01), especially in ischemia reperfusion 24h. PARP-1 expression and the Th1/Th2 ratio had significant positive correlation(r=0.984, P<0.05). Conclusion: Th1/Th2 cells in Balance had related to PARP-1 expression in rat with cerebral ischemia/reperfusion injury.
