During childhood, sports could boost growing development of bone and shape body form, and take precautions against rachitis.

生长发育期运动对骨量的形态结构和维持起重要作用，对骨质疏松有重要干预作用。

All lesions were 7-12 mm in greatest diameter. Seven cases showed a round radiolucency or a thin clear sclerotic rim in middle or up-outer of femoral neck on X-ray film.

结果：8例股骨颈疝窝均为单侧单发病灶，X线平片仅显示7例，CT均表现为股骨颈前方皮质下类圆形骨质缺损，内为较均匀液体密度，边缘清楚伴有硬化缘，最大径线为7-12 mm.7例在X线平片上表现为股骨颈中轴线或其外上方的类圆形透亮区或硬化环。

Focal osteoporotic bone marrow defect of the jaw, most commonly seen in the posteriormandible of middle-aged women, is a radiolucent lesion.

Results Etiological analysis for 40 cases of bone fracture patients indicated the disease was due to bone rarefaction and blood calcium reabsorption.

结果通过对40例骨折患者的病因分析，认识到该疾病是由骨质疏松、血钙重吸收所致。

In previous studies, Cyclooxygenase-2(COX-2) is believed to be linked with inflammations and tumors. But in recent reports, COX-2 is found to play important roles in osteoblastic mechanotransduction and in bone remodification and resorptions in some ways. It was found that mechanical stretches, such as hydrostatic forces and pulsating fluid flow, could increase the expressions of COX-2 mRNA and then prostaglandins, and activate many signal pathways in osteoblasts.

环氧合酶-2(cyclooxygenase-2，COX-2)以往被认为与炎症、肿瘤等有密切关系，近年研究发现它在骨骼重建、骨质吸收以及成骨细胞力学信号转导中发挥着重要作用，主要表现为机械牵拉、流体力、节律性液体流(pulsating fluid flow，PFF)等机械刺激均能引起成骨细胞COX-2高水平表达，进而引起前列腺素(prostaglandins，PGs)量的增加，激活成骨细胞内多条信号传导通路。

Osteoporosis, coxa varus,coax dislocation and improper femoral neck osteotomy were the main causes of trochanteric fractures in primary or revisional total hip arthroplasty.

骨质疏松、髋内翻、髋脱位及股骨颈截骨不当等因素是全髋关节置换术及翻修术中股骨大转子骨折的主要原因。
