OBJECTIVE To study the protective effects of exogenous phosphocreatine (CP) on brain injury after cardiopulmonary resuscitation (CPR) in rats.METHODS one handrad and sixty adult male SD rats were randomly divided into 4 groups: control group (group A),CPR group (group B),low-dose CP group (group C,CP0.5g/kg at beginning of ROSC),high-dose CP group (group C, CP1g/kg at beginning of ROSC),Asphyxiation cardiac arrest and CPR model was used in the study.Brain were taken at 0.5h, 3h, 6h, 12h, 24h.The contents of adenosine triphosphate(ATP), adenosjne diphosphate(ADP) and adenosine onophosphate(AMP)in the brain tissue were measured by HPLC, and the values of total denine nucleolldes(TAN) and energy charge(EC) were calculated;the activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase in brain tissue were assayed by spectrophotometric method.The pathological changes of brain were observed under optical microscope.

背景和目的 大量研究表明,炎症在急性脑梗塞的发生、发展中起着重要的作用.Th9细胞是以分泌IL-9细胞因子为特征的一类新型T细胞.IL-4激活STAT6和IRF4,同时TGF-β激活PU.1,抑制T-bet (T-box expressed in T cells)和GATA3 (GATA-binding protein 3),这些因子的联合作用促使Th9细胞的产生.Th9细胞在急性脑梗死的研究甚少

背景与目的 Hsp22广泛存在于哺乳动物的很多组织中,在肌肉、胎盘、心脏和脑组织中高度表达.近来研究发现,Hsp22在神经系统变性疾病的发生发展中发挥着非常重要的作用.在心肌细胞中Hsp22可通过促进细胞存活,抑制细胞凋亡,对缺血缺氧等应激损伤具有显著保护作用.我们运用N2A细胞OGD模型模拟脑缺血再灌注损伤,观察Hsp22的表达变化,并构建Hsp22过表达质粒,观察Hsp22对神经细胞是否具有保

心脏骤停(cardiac arrest, CA)是临床最危重的心脏急症之一,无论是心源性还是非心源性,其病死率都非常高,而造成这一高死亡率的原因在于,心脏骤停/心肺复苏独特的病理生理过程,包括长时间的全身缺血导致的所有组织器官损伤、再灌注期间及再灌注之后发生的其他损害.目前随着相关研究的深入,心脏骤停后的ROSC率已得到了改善,但是该类患者的远期预后并无根本改变,氧供和氧利用的受损被认为是造成这一
