骨质疏松的

Assessment of calcaneum bone quality and quantity using quantitative ultrasound can be an effective method in screening and preventing of osteoporosis in aged cohort.

近年来发展起来的定量超声法(Quantitative ultrasound，QUS)利用超声对物质密度、结构及材料的特征表现来评价骨的质量，已被证实与双能X线骨密度测定(Dual一cnergy X一ray absorptiometry，DXA)具有良好的相关性，因而成为一种适宜于在大规模人群中筛选骨质疏松高危患者的经济、方便的检测方式l，幻。

Feb. 28, 2005 — All patients with osteoporosis should be screened for celiac disease, according to the results of a single-institution study published in the Feb. 28 issue of the Archives of Internal Medicine . However, the editorialist suggests that more study is needed before generalizing, especially because a number of the cases should have been diagnosed independently from symptoms.

Feb。 28， 2005 -一项刊载於2月28日内科学志，由单一研究机构所进行的研究结果显示，所有骨质疏松症的患者皆应该接受腹腔疾病的筛选；但是，该期刊编辑人员建议，在将该研究结果一般化之前，应该进行更多的研究，特别是，有一些案例应该接受非症状性的诊断。

In order to further explore the benefits of reasonable exercise on maintaining bone health and examine the effect of exercise on skeleton of young college students, 20 male students of college were divided into exercise group (participates bodybuilding frequently) and control group, some indexes of bone metabolism and bone mineral density were observed and analyzed.

为了进一步论证科学合理的运动有利于维持骨骼的健康和对骨质疏松症的预防作用，揭示体育运动对处于青春后期大学生骨骼的影响，本课题在对部分有关骨代谢的研究成果进行理论研究的基础上，以我校20名男性大学生为实验对象，分为运动组和对照组，观察并分析体育运动对大学生骨密度和骨代谢的影响。

The purpose of this paper is to discuss the degree that different swimming exercise affect the bone mass and bone biochemical marker of rats that was in the growth period, to investigate its possible mechanisams, to further enrich the theory that physical activity can promote the healthy of bone.

本研究的目的是：通过动物实验探讨不同强度的游泳运动对生长期大鼠骨量积累的作用效果及对骨代谢生化指标的影响，并探讨其可能的作用机理，进一步丰富体育运动促进骨健康的理论；同时为青少年选择合理的促进骨骼生长、获得较高的基础骨量、预防骨质疏松症运动处方提供一定实验理论依据。

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 influencing factors of femoral necrosis included the degree of healing activity, the dosage summation of corticosteroids, and length of ictus therapy. The influencing factors of bone density included age, dosage summation, and length of ictus therapy. The influencing factors of the bone fabric and flexibility included the use and length of ictus therapy. Statistics showed that serum IgG was not related with avascular necrosis of femoral head and osteoporosis.

股骨头缺血性坏死的影响因素有后期活动量、糖皮质激素总量和糖皮质激素冲击疗法的持续天数；骨密度的影响因素有年龄、冲击疗法和糖皮质激素总量；骨结构和骨弹性的影响因素有冲击疗法、冲击疗法持续的天数；血清抗体IgG与患者康复期股骨头缺血性坏死、骨质疏松在统计学上无联系。

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。

To some degree, this study revealed the relationship between ossein and bone miner and the important preventive and therapeutic effects of ossein on OP. It provides theoretical and experimental basis for the research and development of effective prescriptions to cure OP. Limited by the actual experimental situation, we only did some study on the synthesis and content of type Ⅰ collagen. Further study on the changes of decomposition and structure of type Ⅰ collagen are needed to be done.

本课题的研究，在一定程度上揭示了骨胶原纤维和矿物质之间互根互用的辨证关系，及Ⅰ型胶原在骨质疏松症的发病和治疗中所起的重要作用，并为开发研制治疗本病的有效中药复方提供了理论和实验依据，但由于条件所限，本研究仅就Ⅰ型胶原的合成及其含量变化做了初步观察，而本病中骨胶原纤维的分解代谢及其结构的改变，尚待进一步探讨。

PMMA is the most used lesion filling at present; There is not significant difference between unipedicular and bipedicular vertebroplasty; Using vertebral body venography and appropriate dense bone cement can reduce leakage; Bolster for self-replacement can rebound vertebral body height, and Balloon-PKP and Sky-PKP can be avoided; In order to reduce refracture of vertebral body, anti-osteoporosis drugs should be used.

PMMA是目前最常用的填充物；单侧注射和双侧注射疗效没有明显差别；应用造影剂及掌握合适的骨水泥黏稠度可以减少骨水泥的渗漏率；术前腰部垫枕自身复位可以恢复椎体的高度，避免采用操作复杂且价格昂贵的球囊－PKP及Sky-PKP；进行PVP时应该配合应用抗骨质疏松药物，以减少椎体再骨折的发生。

Dr. Umberto Maggiore, explained that people on a low-calcium diet excrete less calcium in their urine but more of the other substance that combines with calcium to form most kidney stones.

许多医生曾告诉这些患者减少钙的摄入，因为大多数肾结石的成份是钙。但是最近的研究已表明，低钙饮食不仅不能预防肾结石，甚至会促使它的生成，还伴有骨质疏松。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
