阻滞

We conclude that continuous positive airway pressure increases the spread of sensory blockade in thoracic epidural anesthesia, primarily by a more caudad extension of sensory blockade.

节段。结论：持续气道正压通气可以增强胸段硬膜外麻醉感觉阻滞的扩散，主要为增强尾向感觉阻滞的扩散。

RESULTS: There were no significant differences between thetwo groups in the maximum cephalad spread of sensory block orthe time to maximum sensory level.

结果：两组之间比较感觉阻滞的最高平面和达到最高感觉阻滞水平的时间没有显著性差异。

The reflection of decompression was observed during the carotid sinus chirapsia before cervical plexus block, while not during the carotid sinus chirapsia or stimulating vagus after cervical plexus block.

颈丛神经阻滞麻醉前按摩颈动脉窦可引起明显的减压反射，而阻滞后按摩颈动脉窦或刺激迷走神经均未引起明显的血压及心率变化。

The circinal cavities were found in calcium alginate beads and the cylinder holes were observed in zinc alginate beads from the SEM,which indicated that the volume of fraction of zinc alginate polymer was relatively bigger and the zinc alginate polymer chain was more rigid than that of calcium alginate .

凝胶的SEM照片可见，海藻酸钙的冷冻干燥颗粒内为较大的圆孔，海藻酸锌凝胶内为较小的长孔，表明海藻酸锌高分子链在凝胶颗粒中的体积分率相对较大同时刚性较强；卵清蛋白从海藻酸凝胶颗粒中释放的试验结果表明，由于上述海藻酸锌凝胶的特性，导致海藻酸锌对卵清蛋白扩散阻滞作用相对较强；根据试验数据计算得卵清蛋白在海藻酸钙、海藻酸锌凝胶颗粒中的扩散系数分别为1.19×10-7、0.07×10-7cm2/s，利用阻滞模型计算得海藻酸锌高分子链在凝胶颗粒中体积分率约为海藻酸钙高分子链在凝胶颗粒中体积分率的1.7倍。

By FCM analy sing, p53 gene can induce cells apoptosis and make it G1 arrest; Cisplatine can induce cell apoptosis and make it G2 arrest.

流式细胞计数证实p53能诱导QBC939细胞发生凋亡并导致其发生G1期阻滞，顺铂能诱导QBC939细胞发生凋亡并导致细胞发生明显的G2期阻滞。

Both U937 and K562 cells were found arrested in G0/G1 phase when interfered by gambogic acid, while the percentage of cells in S phase was decreased accordingly.

此外，藤黄酸也不是对所有白血病细胞均有诱导周期阻滞作用，HL-60细胞可能在其发生周期阻滞前即已凋亡。

Physical examination revealed homolateral tenderness of supraorbital notch and para-arteria temporalis superficialis. Severity of headache improved dramatically after nerve block therapy.

本组患者术后发生眶上神经痛13例(9.8%)，除1例药物治疗有效外，其余12例经神经阻滞治疗后疼痛明显减轻(P.01)；颞浅神经痛4例(3%)，3例经药物治疗、1例经神经阻滞治疗后痊愈。

We performed a study to determine the actual location of local anesthetic when ilioinguinal/iliohypogastric nerve blocks are performed using landmark-based techniques in children in an attempt to explain a failed block.

我们做了一项研究来观察在定位技术下儿童髂腹下/髂腹股沟神经阻滞时局麻药的实际分布位置，试图以此来解释无效的神经阻滞。

After basal anesthesia, ilioinguinal/iliohypogastric nerve blockades was administed in nerve block group, paracetamol group received rectal paracetamol, control group had not any medication.

各组患儿行基础麻醉后，神经阻滞组行患侧髂腹股沟／髂腹下神经阻滞；对乙酰氨基酚组经肛门塞人直肠对乙酰氨基酚栓剂；对照组未予任何药物镇痛。

Results The anesthesia range was narrowed and anesthesia duration was shortened with the prolongation of epidural catheter placement,Epidural roentgenography showed that the medium diffused normally within epidural space,biopsy of epidural tissues showed that there were inflammative cells infiltration and fiber proliferation with longer epidural catheter placement（more than 4 weeks）,without significant differences between both groups.Conclusion Epidural corticosteroids can not prevent epidural adhesion from occurrance induced with long-term epidural catheter placement.

结果 随着硬膜外腔置管时间延长，麻醉阻滞范围变窄，麻醉阻滞时间也明显缩短，两组之间没有明显区别；硬膜外腔造影显示：造影剂在硬膜外腔扩散良好，无明显受阻；组织学检查显示：置管时间长(4周以上)的动物，硬膜外组织炎细胞浸润、纤维组织增生、硬膜增厚，而且随置管时间延长，这&种变化更&加显著，但两组之间没有明显区别。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.

采用曲线坐标系下压力与速度耦合的SIMPLER算法，数值研究了周期性渐扩渐缩波纹通道内脉动流动与换热情况，流动Re数的范围为10~1000，Pr数为0.7。
