在我们的研究中，我们已经表明，三个序列夹闭双侧颈总动脉，每次持续一分钟，随后再灌注五分钟，是一个足够的缺血PC刺激诱导早期的IT。 此外，我们已经证明，使用预处理协议是一个安全和未成年人的侵入性手术没有值得注意的术后并发症发生率，没有迹象表明在脑细胞凋亡和无死亡。先前6-7,12已经描述了几种不同的预处理协议。其他已经使用了6分钟夹闭双侧?...

缺血性中风是一种疾病，死亡率高和一个巨大的社会经济负担1。尽管密集的实验和临床科学纵观近十年的努力，急性缺血性脑卒中患者的治疗选择仍然非常有限2。在对比的是，在发达国家，老年人的比例的增加将显着增加缺血性中风患者的发病率和患病率与未来几十年中3。因此，迫切需要新的治疗策略与缺血性中风患者。 一种方法是应对破坏性刺激大脑内源性适应机制，以获得进一步的了解。这种脑源性的神经保护作用也被称为缺血预处理（PC）或脑缺血耐受（IT），并描述了一种现象，其中施加到大脑的非破坏性的伤害性刺激，诱导瞬态电阻对后续的损害缺血性损伤4。 IT发生在两个不同的时间窗口：早期的IT分钟到几个小时后，PC内发生延迟，这需要一个延迟了几个小时，发生4。 到目前为止，一直专注于IT研究脑延迟IT。少得多称为早期IT的机制。这项研究的目的是建立双侧颈总动脉闭塞（夹闭双侧颈总动脉），这是一个既定的刺激诱导延迟IT，作为充足PC刺激诱导早期局灶性脑缺血（大脑中动脉闭塞引起的缺血） C57BL6 / J小鼠。 在这两个手术（夹闭双侧颈总动脉缺血），通过激光多普勒血流仪（LDF）监测脑血流（CBF）进行。 夹闭双侧颈总动脉进行了在麻醉和自主呼吸小鼠。暴露双侧颈总动脉（CCA）和闭塞，持续60秒，然后通过5分钟的再灌注。此夹闭双侧颈总动脉/再灌注序列重复两次。手术后，老鼠恢复得很快，没有任何迹象表明，功能障碍。为了排除，夹闭双侧颈总动脉上述协议并未导致延迟在脑细胞的死亡，我们在执行一个TDT介导的dUTP-生物素缺口末端标记法（TUNEL）染色72小时后，夹闭双侧颈总动脉（或假手术）独立成团。 缺血诱导局灶性脑缺血啮齿动物5-7是一个广泛建立的模型。手术进行了使用标准化作业程序（SOP）8。曝光后的左CCA，硅覆盖的单丝引入的前端CCA，先进到Willis环通过内颈动脉（ICA），直到大脑前动脉（ACA），从而，中脑动脉的起源（ MCA）闭塞定义的一段时间。在这项研究中，我们用45分钟的缺血，这通常会导致的缺血性病变在马华境内涉及纹状体和大脑皮质区。 在我们的研究中，我们分析了早期使用夹闭双侧颈总动脉作为PC刺激时空的档案。我们的数据表明，夹闭双侧颈总动脉缺血的最佳时间之间的延迟引发早期的IT是30分钟。 在这段视频中，我们将给予两个外科手术， 即夹闭双侧颈总动脉缺血的示范。
