1 The approach of LVB cannulated by passed retrograde across the aortic valve can be performed easily and reduce LV pre-load and LV work, as well as cardium oxygen consumption significally; 2 This LVB can improve coronary artery perfusion and cardiac function while AOMP can be maintained after LAD occlusion; 3 There has a potential impariment effect on the right ventricular function with excessive amount BFR (over 85%) during LVB, particularly in the present of myocardial ischemia; 4 Roller pump is not suited for a prolonged bypass because of significant damage to the blood system.

由此我们得出以下实验结论：经外周动脉逆行左室置管转流方法操作简便、迅速。能明显减少左室前负荷，减少左室作功，降低心肌耗氧量；能维持严重心脏缺血后的平均动脉压，改善冠脉循环灌注和左室功能，具有临床应用的可行性。85%以上转流率对缺血心脏的心功能有潜在的损害效应。以75%左右转流率较为合适。转子泵不适宜用作长时间转流。

Short T1 hyperinsense appearing behind cerebral ischemia is not resulted from the bleeding but from various carious factors,so it is very important for the clinical treatment.

脑缺血后出现短T1高信号并非出血，而是多种因素综合所致，这对临床正确治疗选择很有意义。

Objective: To investigate the effect of carthamus tinctorius injection on expression of caspase-3 and bcl-2 after renal ischemia/reperfusion injury.

目的：探讨红花注射液对大鼠肾缺血再灌注损伤凋亡相关基因Caspase-3和bcl-2表达的影响。

To summarize, theinjection of Carthamus tinctorius has function of protective and therapeutical effect on rats with acute myocardial ischemia.

提示红花注射液对急性心肌缺血所致的大鼠心脏损害可通过改善缺血心肌功能，抑制心脏损伤后的炎症反应，影响凋亡相关基因的表达而具有保护和治疗作用。

Objective To investigate the effects of Carthamus tinctorius on infarction volumes,apoptosis of neurons and bcl-2,caspase-3 expressions after acute injury of cerebral ischemia and reperfusion.

目的 探讨红花注射液对大鼠急性脑缺血再灌注损伤后梗死体积和神经元凋亡及凋亡相关蛋白bcl-2，caspase-3表达的影响。

Carthamus tinctorius injection has significant effect on the up-regulation of bcl-2 and down-regulation of caspase-3 expression in renal ischemia/reperfusion injury.

在肾缺血再灌注损伤过程中，红花注射液具有抑制Caspase-3表达和促进bcl-2表达的作用。

Methods Density gradient centrifugalization combined with adherence method were used to segregate and cultivate rat MSCs. MSCs cultivated to the 3 rd passage were characterized using flow cytometry technique. TGF-β1 with 1, 2 and 5 μg/L were pretreated on MSCs for 8 h, then serum and oxygen deprivation were used to cause analogous ischemia of MSCs in vitro. AnnexinV/PI flow cytometry technique was used to evaluate apoptosis and survival of MSCs.

采用密度梯度离心结合贴壁法分离、培养大鼠MSCs，对培养第3代的MSCs进行鉴定；用1、2、5μg/L的TGF-β1分别预处理细胞8 h，然后用血清剥夺和低氧处理建立MSCs体外模拟缺血性损伤模型，通过流式细胞术评价MSCs的凋亡及存活情况；用Western blot方法检测2μg/L的TGF-β1对Akt和p-Akt表达的影响。

Objective To study the protective effect and mechanism of endothelin-1(ET-1)-re- ceptor antagonist PD142893 on early ischemia-reperfusion injury in rats lung allografts.

肺缺血再灌注损伤是肺移植术后早期死亡的主要原因，寻找有效方法预防和减轻肺IRI，有着重要的临床意义〔'一3〕。
