It has been found that AM significantly reduced acenaphthene content in soils. The degradation rates of acenaphthene in soils with inoculation of Glomus mosseae and Glomus etunicatum were 32 7%-45.2%, increased by 6.8%-9.8% than the control.

结果表明，AM作用下土壤中苊总残留量明显降低；接种摩西球囊霉菌Glomus mosseae或幼套球囊霉菌Glomus etunicatum后，供试两个污染土样中苊总残留降解率达32.7%~45.2%，比未接种对照高

First, For the coronary artery stent, two kinds of loads, including the pressure named 〓 derivatively from the balloon and the counterforce named 〓 on the wall edge of the stent, have been taken into account in the analysis of the stent.〓 and 〓 were changing as the stent expanding. So, the expansion process of the stent could be considered as the process composing of many extremely short equilibrium processes, where 〓 and 〓 could be regarded as constants and the stresses, the strains and the displacements were obtained using NFEA in every processes. Then, the stresses, the strains and the displacements obtained in every processes or steps were added up to get the final structure of the coronary stent.

首先，解决了支架有限元分析的载荷非线性问题，认为医用心血管支架受到两种载荷的作用：球囊直接传递的压力〓和球囊对不锈钢支架丝壁边缘的反作用力〓，这两种载荷在支架分析中必须都考虑进去；〓为非线性载荷，随着支架扩张不断变化，处理时将支架扩张的整个过程看成由37个很短的平衡过程组成，在每个过程中取〓为常量，采用有限元法获得应力、应变、位移，最后将各过程的应力、应变、位移迭加起来就获得了不锈钢支架总的应力、应变和位移；本研究用变分法和有限元法模拟杆件拉伸证明了上述方法是合理的。

Art of figuration of the protruding after classics skin centrum (Percutaneous Kyphoplas-ty, PKP) is to be in art of figuration of classics skin centrum (Percutaneous Ver-tebroplasty, the technology of small innovation of surgery of a rachis that the development on the foundation of PVP) rises, its fundamental is the buy inside preexistence centrum enters but expansile ball bursa , the dilate that carries ball bag forms a cavity inside centrum, again infuse stuff stuff, correct deformation thereby, achieve constrictive to a few osteoporosis or tumour centrum that bring about fracture (Vertebral Compressionfractures, the remedial purpose of VCFs).

梗概： 经皮椎体后凸成形术(percutaneous kyphoplas-ty，PKP)是在经皮椎体成形术(percutaneous ver-tebroplasty，PVP)的基础上发展起来的一项脊柱外科微创新技术，其基本原理是先在椎体内置入一个可膨胀性球囊(inflatable bone tamp，IBT)，通过球囊的扩张在椎体内形成一个空腔，再注入填充材料，从而纠正畸形，达到对一些骨质疏松或肿瘤等导致的椎体压缩性骨折(vertebral compressionfractures，VCFs)的治疗目的。

The degradating and redistributing of ECM were migration of VSMC and vascular remodeling through inhibiting the production of PDGF-BB and the activation of MMPs so to prevent the vascular stenosis.⑤Orthotopic hybridism in situ: The expression of MMP-3 increased after operation, the tendency and intensity were parallel to the expression of NF-κB. Tongxinluo could decrease the expression of MMP-3 and NF-κB. The study showed that the producting and activating of MMP-3 were modulated by NF-κB. The inhibition to the producting and activating of MMp-3 of Tongxinluo was mediated by inhibiting the activating of NF-κB. Conclusion ①The rabbit vascular stenosis model could be established successfully by plain balloon damage, the operation process was easy, economical and practical.

①单纯球囊损伤可成功建立典型家兔血管狭窄模型，操作方法简单，经济实用；②以VSMC增殖、迁移为主的内膜增厚以及以ECM降解、合成与再分布所致的血管重构是导致受损血管狭窄的根本原因；③通心络能明显抑制VSMC的增殖、迁移和ECM降解、合成，阻止血管内膜增生和血管重构，防止受损血管狭窄；该作用可能与其减少和阻止PDGF-BB的产生和活性，以及抑制MMPs的表达和恢复MMPs/TIMPs平衡有关；④通心络能显著抑制球囊损伤后血管内膜增生和血管重构，可能与其保护血管内皮，改善内皮功能，增加血清NO含量有关；⑤通心络抑制内膜增生和血管重构，减轻受损血管狭窄，还可能是通过抑制NF-κB的活化途径而起作用的。

Objective: To determine if an aggressive approach to coronary revascularisation with oversized balloons is counterproductive, we studied the effect of increasing balloon-to-artery ratio on neointimal hyperplasia following primary stent placement using a non-atherosclerotic porcine coronary overstretch model.

目的：为了确定在冠状动脉重建术中使用过大的球囊这种过于积极的措施是不是有反作用，我们研究了首次支架置入术后增加的球囊比动脉比值对新生内膜增生的影响，模型是没有动脉粥样硬化的猪的过度牵张的冠状动脉。

This experiment goes like this: with the operation of from anterior neck, Embedded the pressure Saccule which is converted by the silica gel catheter in canine cervical vertebral body and then infuse slowing gradually certain amount of X ray contrast medium to form the gradual chronic pressure on the ventral lateral spinal cord so as to reach the pathology effect of the pressure on the segment imitation the spinal cord.

本实验采用硅胶导尿管改制成的压力球囊，经颈前路手术，在成犬的椎体内置入压力球囊，逐次注入一定量的X线可显影的液体，形成颈段脊髓慢性渐进性压迫，达到了节段解放军总医院军医进修学院硕士研究生论文中文摘要性模拟颈脊髓腹侧慢性受压的病理效果。

Balloon dilatation device for achalasia of cricopharyngeal muscle is design based on the principle of expansion treatment to stimulate cricopharyngeal muscle contraction and dilatation through the pressure of balloon dilation.

环咽肌失弛球囊扩张治疗装置设计是以球囊扩张治疗原理为基础，通过球囊扩张的压力带动环咽肌收缩舒张以达到治疗的目的。

The contents of other metal elements Na, Mg, K, Al, Mn and Pb in lagenal otoliths were not significantly different from those in utricular and saccular otoliths.

瓶状囊耳石中其它金属元素Na、Mg、K、Al、Mn、Pb的含量与球囊和椭圆囊耳石相比无显著性差异，但Zn、Ba、Cu的含量低于球囊耳石。

The contents of other metal elements Na, Mg, K, Al, Mn and Pb in lagenal otoliths were not significantly different from those in utricular and saccular otoliths.

The contents of metal elements Zn, Ba and Cu in lagenal otoliths were lower than those in saccular otoliths. Conclusion The contents of magnetic elements in lagenal otoliths of homing pigeons are not much higher than those in utricular and saccular otoliths, which does not support the hypothesis that birds depend on high contents of Fe and Zn in lagenal otoliths for sensation of geomagnetic information.

结果表明成年信鸽瓶状囊耳石中磁性元素的含量极低而且不比内耳球囊和椭圆囊耳石更丰富，从而不支持信鸽因其瓶状囊耳石中含有较高的Fe、Zn等元素而能够感受地球磁场这一假说。

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。
