| 摘 要： | 目的探讨大鼠全脑缺血再灌注后皮质组织中HAX-1蛋白(HS1-associated protein X-1,HAX-1)与皮质神经元凋亡的关系。方法建立大鼠四血管法全脑缺血模型,将实验动物分为5组(n=5):正常组,缺血6、24、48、72h组。采用HE染色,观察大鼠皮层组织病理变化;采用免疫组化、TUNEL法检测大鼠全脑缺血再灌注后HAX-1蛋白的表达以及皮质神经元凋亡蛋白Caspase-3的表达情况。结果HAX-1蛋白在缺血后6h表达最高(37.60±3.45),24、48、72h降低[分别为(11.40±1.14)、(10.40±1.52)、(9.80±1.30)],且低于正常水平(P<0.01);Caspase-3蛋白随着缺血时间的延长逐渐增高[6、24、48、72h分别为(72.80±5.49)、(106.20±6.91)、(129.00±19.74)、(166.20±15.32)](P<0.01),并伴随神经元凋亡的数目逐渐增加[(92.00±9.06)、(133.80±10.64)、(157.00±10.83)、(187.80±14.96)]。结论全脑缺血再灌注后皮质神经元中HAX-1蛋白在短期...

| Abstract: | Objective To investigate the relationship between HS1-associated protein X-1 (HAX-1) expression and neuron apoptosis in rats after global cerebral ischemia reperfusion injury. Methods Rats were subjected to global cerebral ischemia reperfusion injury through four-vessel occlusion, and then the experimental rats were divided into 5 groups, normal group (NC), 6, 24, 48 and 72 h post injury groups (n=5 for each group). Immunohistochemistry and TUNEL were used to detect HAX-1 expression and activated Caspase-3,... |
