To avoid the rebar cage uplifts, the speed of concrete casting should be lowered down when the concrete is cast to about 1m under the rebar cage's bottom; when the casting progresses to 4m above the bottom of the rebar cage the tremie should be lifted up to ensure it's bottom is 2m above the rebar cage's one, and then the normal casting speed can be resumed.

为防止钢筋骨架上浮，当灌注砼顶面距钢筋骨架底面1m左右时，应降低砼灌注速度，当砼上升至钢筋骨架底面4m以上时，提升导管，使其底口高于骨架底部2m以上，即可恢复正常砼灌注速度。

Every group rats were divided into two parts with the same rats. At last the rats were redivided ,then them were killed and their brains were excluded after one hour.4 hours or one week.Results PO2 and cerebral blood flow of E-selectin 2mg/kg group were higher than that of saline and lower than that of l0mg/kggroup(p.01).The volume of cerebral infarct and blood speed of E-selectin 2mg/kg group was smaller than that of saline and larger than that of l0mg/kg group(p.01).At the same time PCh.speeds.flows and the volume of infarct were related with the time (p.01).Conclusion E-selectin can effectively increase PC2 and rCBF after ischemia and reperfusion .reducing infarct volumes and speeds of blood at the same time . Artificial synthetic E-selectin can effectively reduce the reperfusion injury following cerebral ischemia.

结果 生理盐水组，2mg／kg组，10mg／kg组PO_2值依次提高(p＜0.01)，脑皮质血流量依次提高(p＜0.01)；脑血流速度依次减低；脑梗死体积依次减少(p＜0.01)；同时在测定的时间段里PO_2和脑组织血流量值与时间成正相关(p＜0.01)；脑梗死体积和脑组织血流速度值与时间成正相关(p＜0.01)。E一选择素在脑缺血再灌注损伤中表达的实验研究中文摘要结论E一选择素能增加脑缺血再灌注损伤的脑组织氧饱和度，脑血流量，减低脑血流速度；减少脑损伤体积；从而保护了脑缺血再灌注损伤的脑组织。

After 60 mm of ischemia/reperf黶ion, the expression of 11-8 was recognized more strongly on postsinusodial venules and sinusodial endotbelial cells,and lots of neutropblls infltrated in liver tissue. Wher~s, after 240 mm of reperllision, IL-S imniunobistochemical stainning fade more obviously than before, quantities of neutrophils sequestrated in liver leading to hepatic cells injury.

结果发现：肝缺血再灌注后60分钟，肝脏小叶中央静脉周围和肝窦状隙内皮细胞表面IL-8呈强阳性染色，此时肝组织中可见大量散在中性粒细胞浸润，于再灌注240分钟时，IL-8组化染色变淡，但分布部位与再灌注60分钟时相似。

Lead on to the defect in pile body of bored caisson pile, mainly relate to wall mud, boring drill rate, 3 materials of concrete, water cement ratio and mixing quality controlled by concrete under water when pouring, self defect of pouring conduit, and operation way heighten conduit, and so forth.

导致钻孔灌注桩桩身缺陷，主要与护壁泥浆、成孔钻速、组成砼的三大材料、在灌注时水下砼控制的水灰比及搅拌质量、灌注导管的自身缺陷、以及提升导管的操作方式等有关，根据一些工程实例，分析了形成桩身缺陷的具体原因，并提出了防范措施。

Rats were randomized into an experimental group (n=7), in which limbs were selectively perfused with a cooled isotone heparin solution at a limited flow rate before blood flow was restored, and a conventional group (n=7; uncontrolled blood reperfusion).

将上述7只大鼠随机分配到试验组中，在血流量恢复前，大鼠肢体选择性灌注冷却的等渗肝素溶液并限制灌注流速。常规组（7只大鼠）采用非控制性血液再灌注。

结果表明，舌表面温度随血液灌注率的增加而升高，但血液灌注率增大到一定值后，舌面温度将维持不变，血液灌注率值也不再增长。

Perfusion in the right parietal lobe in group2 was significantly lower than in group1 (P.01).（2）Average perfusions were higher in the right temporal and parietal lobes than in the left in all 3 groups.（3）Gray matter volumes were significantly smaller in group3 than in group2 (P.05); total cerebral spinal fluidsvolumes were significantly larger in group3 than in group1 and group2（P.05）; right hippocampus volumes were significantly smaller in group3 than in group1 （P.05）. Conclusions Age-related change of cerebral blood perfusions in the healthy elderly over 65 years is characterized with hypoperfusion in the right parietal.
