中轴骨

Living bones consist of bony substance, periosteum and bone marrow, and are abundant in blood and nerve supply.

分类 根据骨在体内的部位，可分为颅骨、躯干骨和四肢骨三大类，其中躯干骨和颅骨统称为中轴骨。

The experimental results suggested that Davallia mariesii and Araiostegia parvipinnata have enriched antioxidant components and better antioxidative activity.

首先，测定上述七种植物水抽取物总多酚类之含量，结果显示以海州骨碎补、鳞轴小膜盖蕨含量最多；在多种抗氧化活性测定中，亦以鳞轴小膜盖蕨、海州骨碎补具较佳之活性。

Upper central incisors moved forward and downward together with maxillary, at the same time they upright in the sagittal plane and tip mesially. 3 The occlusion plane rotated clockwise for about 1.5°. 4 The width increasement effect of RME comes from approximately the equal amounts of skeletal and dental expansion. The mode of dental movement was a combination of body and tipping movements of posterior teeth.

结果：1后牙在宽度方向上为整体移动和倾斜移动相结合的移动方式，但第一磨牙和第一双尖牙稍有差别；牙齿和骨对宽度增加的贡献各占约1/2；2后牙在垂直方向有伸长的趋势；3第一磨牙和第一双尖牙均向前整体移动，轴倾度保持不变；4中切牙整体随上颌骨前部向前向下移动，其牙长轴发生直立，轴倾度增加；5上颌平面发生顺时针旋转。

Osteoid osteomas usually occur in the axial skeleton in bone cortex of young males in the second decade of life.

骨样骨瘤常见于十几岁男性中轴骨骼的骨皮质。

BACKGROUND: Bone densitometry using dual energy X-ray absorptiometry is the "gold standard" for osteoporosis diagnosis.

背景：世界卫生组织将双能X射线骨密度仪测量中轴骨骨密度作为诊断骨质疏松症的&金标准&，但其缺点是仅仅提供了面积骨密度，而不是体积骨密度，因此现有的骨密度检查结果评价实际的骨矿含量存在一定的局限性。

The sensitiity of leukocyte scintigraphy in detecting chronic osteomyelitis in the peripheral skeleton was 84%(95% confidence interal, 72% to 91%) compared with 21%(95% confidence interal, 11% to 38%) for its detection of chronic osteomyelitis in the axial skeleton. The specificity of leukocyte scintigraphy in the axial skeleton was 60%(95% confidence interal, 39% to 78%) compared with 80%(95% confidence interal, 61% to 91%) for the peripheral skeleton.

白血球闪烁显像在检测慢性骨髓炎中对于外周骨的敏感性为84％（95％可信区间为72％-91％），而其对中轴骨的敏感性为21％（95％可信区间为11％-38％），白血球闪烁显像在检测慢性骨髓炎对中轴骨的特异性为60％（95％可信区间为39％-78％），而其对外周骨的特异性为80％（95％可信区间为61％-91％）。

BACKGROUND: The HOX gene family is a highly conserved transcription factor family, which affects the formation of basic axis and secondary axis during embryonic development, at the same time, it plays a pivotal role in the development of the central nervous system, axial skeleton, stomach intestine, urogenital system and external genitalia.

背景：HOX基因家族是一个高度保守的转录因子家族，该家族在胚胎发育阶段基本体轴和次级体轴的形成中起作用，同时在中枢神经系统、中轴骨、胃肠和泌尿生殖系及外生殖器和肢体的发育中起重要作用。

During embryogenesis,the axial skeleton is formed by a process called somitogenesis, which produces transient segmental tissue known as somites.Disruptions in somitogenesis have been shown to result in vertebral malformations,including segmentation failure and formation failure.

在脊柱发育的胚胎期，形成一种重要的过渡性组织-体节，体节决定中轴骨的形成，已经证明体节发育受影响可导致脊椎畸形，包括脊椎形成障碍和脊椎分节不良。

Intra-arterial embolization, a technique particularly useful for tumors located in the axial skeleton, has been shown to devascularize tumors, reduce their size, induce calcification of their margins, and alleviate pain.

对于中轴骨肿瘤具有独特优势的动脉栓塞技术，已证实具有减少肿瘤血管、缩小肿瘤体积、诱导边缘钙化和止痛的作用。

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。
