| 目的：探讨应用PDTC抑制核转录因子κB (NF-κB)对兔蛛网膜下腔出血模型基底动脉中的表达及其对脑血管平滑肌增殖的影响。方法：将16只雄性新西兰大白兔随机分为2组，SAH组和PDTC组各8只，枕大池二次穿刺并注入自体动脉血组为SAH组， SAH组应用PDTC注入枕大池作为干预组。模型制作完成后7d处死动物，取其基底动脉测量平滑肌厚度。免疫组化法及Western-blot法检测基底动脉中NF-κB、PCNA蛋白的表达。结果：与SAH组相比， PDTC干预后，基底动脉中NF-κB与PCNA蛋白表达减少，平滑肌厚度变薄，与SAH组比较具有显著差异性(P<0.05)。结论：PDTC可通过抑制NF-κB的激活减轻SAH后脑血管壁平滑肌增殖性改变。 |

| Abstract: |
| ABSTRACT Objective Aim to investigate the impact of cerebrovascular smooth muscles proliferation to utilize PDTC inhibit the expression of NF-κB rabbit model after subarachnoid hemorrhage(SAH)in the basilar artery. Methods Sixteen New Zealand male rabbits were randomly divided into two group，PDTC group and SAH groups eight each other。And using double injections of fresh autologous arterial blood into the cisterna magna to establish animal models of cerebral vasospasm．Injected PDTC to cisterna magna of SAH group each day as PDTC group. After injection 7th day,the expression of NF-КB of basilar artery in rabbits were determined by immunohistochemistry and Western blot；morphological changes of rabbit basilar artery was also observered . Results.Compared with SAH group, applied the PDTC intervention, the expression of NF-κB p65and PCNA protein decreased, and smooth muscles thickness became thinner, compared with SAH group has significant differences (p＜0.05). Condusion PDTC can reduce the proliferation of smooth muscle through the inhibition of the activition of NF-κB p65 after SAH. |
