脊柱的

Recombinant Human Osteogenic Protein (rhOP-1) provides a strong arm to solve this difficult problem. The rhOP-1 is produced by DNA recombinant technique, with the characteristics of high purity, high output, low cost and high osteoinductive activity. How does OP-1 work on the erective spinal fusion?It has not been documented yet.

重组人OP-1（rhOP-1）的出现为这个问题的解决提供了一个强有力的武器。rhOP-1是通过DNA重组技术生产，具有纯度高、产量高、成本低等优点，具有高效的诱导成骨活性。rhOP-1在直立脊柱融合术中的作用如何，目前尚未见文献报道。

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。

From traditionary nucleus pulposus exsection to spinal fusion,endoscope and minimally invasive techniques,and prosthetic disc nucleus and artificial disc replacement in recent years, however,they relieved clinical complaint temporary by means of the destruction of structure and function of lumbar intervertebral disc.

从传统的髓核摘除术到脊柱融合术、内窥镜和微创技术及近年开展的人工髓核和椎间盘置换术，但它们都是以破坏椎间盘结构和牺牲生物力学功能为代价的，不能阻止和逆转椎间盘退变，因此椎间盘退变的基因治疗和组织工程成为研究的热门课题。

Now it is important that none of the many plans which have been devised to teach a child to walk, should be adopted the go-cart, leading-strings, etc.; their tendency is mischievous; and flatness of the chest, confined lungs, distorted spine, and deformed legs, are so many evils which often originate in such practices.

现在，这是非常重要的，没有很多的计划已经制订，教导儿童走路，应通过去购物，领先弦乐团，等；其趋势是恶作剧；平坦的胸部，只限于肺部，扭曲的脊柱，变形的两条腿，有这么多邪恶的往往起源于这种做法。

Results (1) 6 cases of Tuberous Sclerosis. Diffused subependymal nodular calcification lesions were found in all cases on unenhenced CT. 4 patients are 2 pairs of mother/child relationship. Both of the two mothers are found to suffer from renal angiomyolipoma.(2)1 case of neurofibromatosis showed abnormal spinal canal: scoliosis of thoracic and lumbar spine, concave change of vertebral posterior border. Bilateral renal hypogenesis was found in this patient. Diffused hyper-density lesions were found in kidney and fatty accumulation was found in back skin.(3)6 cases of Sturge-Weber syndrome. On unenhenced CT, curving and strip-shaped calcifications were found along the parietal and occipital gyrus.

结果 ①结节性硬化6例，所有病例CT平扫见两侧脑室室管膜下多发小结节状高密度钙化灶，其中4例为两对母子关系，并见两位母亲合并有肾脏错构瘤，；②神经纤维瘤病1例，MRI表现为椎管异常，胸腰段脊柱侧弯，椎体后缘呈明显的切凹改变；伴有双肾发育不良，CT示肾内多个高密度影，背部皮肤多量脂肪堆积，③脑颜面血管瘤综合征6例， CT可见顶枕部沿脑回分布的弯曲的条状高密度钙化，部分延伸致侧脑室内，增强后见病灶内有扭曲的条状和结节状明显强化的血管影；④小脑血管瘤病4例，影像学表现为小脑内大囊、小结节样占位性病变。

Methods Six cadaveric lumbar vertebrae were harvested and evaluated with dual-energy x-ray absorptiometry and quantitative computed tomography to assess bone mineral density. Matched, polyaxial pedicle screws were then randomly assigned by side and placed using the Magerl, Krag or caudad trajectory technique assisted by Iso-C 3D scan and 3D navigation system. Cyclic loading tests were performed with a maximum 250 N load at 3 Hz up to 30000 cycles while recording load and displacement. Stiffness quotients were calculated it comparison.

从尸体中获取6节腰椎椎体经DEXA和QCT检测骨密度值，证实为骨质疏松后在计算机导航下按随机分组的方法向12个椎弓根中置人不同方向的椎弓根螺钉，使用MTS-858生物力学仪脊柱力学测试平台进行±250N的循环负荷疲劳测试，记录负荷循环中的螺钉位移，计算系统的刚度系数并进行对比分析。

according to the concept of sagittal spinal balance, the alternating curves of cervical and lumbar lordosis and thoracic and sacral kyphosis enable the head to be positioned over the trunk and pelvis.

根据矢状面上脊柱平衡的理念，颈椎和腰椎的前凸，胸椎和骶椎的后凸构成的交替曲线使头能够定位与躯体和骨盆的上方。

Without doubt, baidu HI is not a simple IM, he is Baidu the rachis of whole product line, it is the soul of the product line of Baidu future and engine, it will be perforative all products with integrated Baidu and service, include to search, stick, know and the series product line such as the C2C platform that is about to roll out.

毫无疑问，百度HI不是一个简单的IM，他是百度整个产品线的脊柱，是百度未来的产品线的灵魂和发动机，它将贯穿和整合百度的所有产品和服务，包括搜索、贴吧、知道以及即将推出的C2C平台等系列产品线。

These are large, sometimes the size of one's leg or one's spinal column, and do great damage to the etheric grid work of the form.
