摘要 容积CT灌注成像(CTPI)技术可有效判断脑组织局部低灌注所引起的微循环障碍的程度,了解急性脑梗死后局部血液动力学的变化[1-2].Toll样受体(toll-like receptors,TLRs)是最重要的固有免疫受体,是介导机体固有免疫转向获得性免疫的桥梁,其成员Toll样受体4(TLR4)生物学作用广泛,参与多种炎症过程,并可调控获得性免疫反应,在急性脑梗死脑损伤的发病机制中起重要作用[3-4].TNF-α (tumor necrosis factor-α)是体内炎症系统的核心因子,已有研究表明其在急性脑梗死中的作用[5].本实验将急性脑梗死患者CTPI的结果与TLR4的表达量及血清TNF-α的浓度进行同步观察,旨在探讨CTPI联合实验室检查在急性脑梗死早期诊治中的应用价值.
