The study concluded:(1)three-dose IM revaccination could keep protective antibody and more importantly immunologic memory for a long time and play an important role for prevention from HBV infection in non-responders, though its efficacy could not reach the level of primary vaccination in responders;(2)although low-dose ID revaccination could induce a high proportion of non-responders to respond to vaccine, its long-term efficacy was significantly poor compared with IM revaccination with the same number of injections.

结果证实：无应答者3针常规剂量肌肉复种远期效果虽然达不到应答者初种的水平，但确能有效维持保护水平抗体、特别是免疫记忆的长期存在，在预防HBV感染方面能发挥重要的免疫保护作用；小剂量皮内复种虽能诱导高的抗体应答率，但远期效果明显不如相同针次常规剂量肌肉复种。

All experiments were carried out under the dry and oxygen-free argon atmosphere by using standard Schlenk techniques.

在无水无氧和纯的氩气保护下，使用Schlenk技术，用2-(C1CH2) C5H4N·HC1与2当量的C9H7Li在THF中冰水浴反应，以73%的产率得到3-(2-C5H4NCH2)C9H7(1)。

Chapter 5"The development on the property right system and theories under the influence of intangible property protection", this chapter points out that under the influence of the intangible property right, the property right system lays more emphasize on its openness, enables it compassing more form of property.

第五章&无体财产保护所推动的财产权制度和理论发展&，指出在无体财产权的影响下，财产权制度更加强调其开放性，使其能够包容新的财产形式。

SMI had protection and therapeutic effects on leucocytopenia of mice induced by irradiation.

试验还显示，照射后四天SMI大、中剂量组小鼠骨髓有核细胞数与正常对照组无显著性差异，说明其骨髓造血功能比较活跃，提示SMI对放射性损伤所致小鼠血虚证有一定的保护和治疗作用，对于小鼠白细胞减少有较好的治疗效果。结论：SMI对小鼠放射性损伤所致血虚证有一定的保护和治疗作用。

When the carbon microsphere s are graphitized under the protection of Ar at 2100～2600℃,closed-cell carbon microspheric form of graphitic structure is produced.

依据微胶囊化原理，用热固性线型酚醛树脂制得微胶囊，加热去除囊芯后用作先驱体，在N2保护下进行900~1100℃的碳化处理得到具有无定型碳结构的闭孔碳微球，然后在Ar气保护下进行2100~2600℃的石墨化处理，得到具有石墨结构的闭孔微球碳泡沫材料。

Result Compared to concurrent control groups, neuromotor function are significantly improved in 1h and 6h experiment group. The indexes of neural cell apoptosis decreased significantly (P 0.01). But in 24h experiment group, the decrease of the index are not statistically significant. Conclusion Early application of rhEPO could lessen the lesion of neuromotor function. The protection is partially due to the reduction of neural cell apoptosis.

结果：与对照组相比，脊髓损伤后促红细胞生成素1小时，6小时实验组神经运动功能明显改善，脊髓神经细胞凋亡指数均明显下降(P 0.01)；而术后24小时组与对照组相比，脊髓神经细胞凋亡指数的下降无统计学意义结论：早期应用外源性EPO对脊髓不完全损伤后引起的神经运动功能损害具有保护作用，此种保护作用可能与EPO能够减少神经细胞凋亡有关。

Methods To observe 110 primiparas of 37～40 weeks' pregnancy,head presentation,who can deliver vaginally with distending the vagina and new protecting perineum method but not with perineal lateralis,and compare with the 108 primiparas with traditional protecting perineum method.

选择孕37～42周，经阴道自然分娩，无会阴侧切指征的单胎头位初产妇110例作观察组，在助产中用扩张阴道和改良托肛加指法保护会阴；以往用传统托肛法保护会阴的108例作对照组。

Using this method, the circuit can be operated without voltaic art and impact current through power electronic AC switch and the switch can be monitored and protected by microcomputer device.

它通过交流电力电子开关实现电路的无电弧、无冲击性操作，同时通过微机装置对开关进行监控和保护。

On the other hand, a higher frequency of CCR-64I allele was also observed in HIV-1 uninfected individuals who were heterosexually exposed to HIV-positive index partners (p=0.164), but most of the reports didn't support this result.

在异性传播病例中，有暴露史而未感染病毒者CCR2-64I的基因频率明显高于感染者，说明CCR2-64I对异性传播有一定的保护作用，不过与以往的研究不一致。多数研究认为，CCR2-64I对HIV-1异性传播无明显保护作用，有研究甚至认为是一种危险因素。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
