Results of histology, SEM and three-point bend biomechanical competence demonstrated that XW630 has promoting osteogenic action obviously. The effects of XW630 for prevention and treatment of osteoporosis and osteoporostic fracture were effectively and much better than estrone.

组织学、扫描电镜及三点弯曲力学测试结果表明：XW630具有促进成骨的作用，可以有效地预防和治疗骨质疏松症及骨质疏松性骨折，其作用优于雌酚酮。

On the plain scan of CT, the appearances of the aneurysmal bone cyst were the various expansile changes. In destruction of bone, the capsular districts and septation can be seen. On MR T1WI and T2WI, we can see the low signal ring of the diseased region borderline, the diseased region bulk was full of fluid which has miscellaneous signals, it can be seen the low or slightly high signal. In the diseased region, the septation which have low signals both on the T1WI and T2WI can be seen.

在CT上动脉瘤样骨囊肿表现为溶骨性骨质破坏，常有不同程度膨胀性改变，骨质破坏区内可见囊状低密度区及骨性分隔，MRI表现为T1WI及T2WI上可见病灶边缘有低信号环，病灶内主体部分充满囊状液体，信号混杂，在T1WI低或中高信号，在T2WI上呈不均匀高信号，病灶内可见T1WI及T2WI上均呈低信号的分隔。

However, it is not known how orthodontic force influences the function of cementoblast and what is the relationship between the function change of cementoblast with root resorption. So we studied the effect of mechanical stimuli on root resoption by examining the expression OPG and RANKL and exploring the related signal transduction pathway in cementoblast. Methods: Cementoblasts OCCM30 were cultured in DMEM with 10% FBS for 48 hours and starved in DMEM with no FBS for 24 hours, then subjected to mechanical strain by four-point bending system with tension and compression stress at 2000μstrain at 0.5Hz frequency. The flow cytometry was used to examine the cell cycle and proliferation activity after 3h, 6h, 12h, 24h loading respectively. OPG and RANKL mRNA were analysed with real time quantitive RT-PCR after the same loading period as FCM.

本课题利用四点弯曲力学加载系统，采用流式细胞术、实时荧光定量PCR、Western免疫印迹等方法，研究体外培养的成牙骨质细胞株OCCM-30在不同力学环境中增殖活性的变化，以及其表达骨保护素和破骨细胞分化因子的mRNA的变化，探讨应力刺激对成牙骨质细胞表达破骨细胞分化调控蛋白的影响，并通过对应力刺激下成牙骨质细胞分裂原活化蛋白激酶家族中的ERK1/2、P38MAPK活性的变化及其与OPG、RANKL基因表达变化关系的研究，对力学刺激调节破骨细胞分化调控蛋白的相关上游信号转导通路进行初步探讨。

AbstractObjectives1 Correlate bone mineral densityto vertebral compressive strengths.2 Consummate the technique for percutaneous polymethylmethacrylate vertebroplasty and observe the pattern of PMMA imaging distribution.3 Determine the strength and stiffness of osteoporotic with or without vertebroplasty with PMMA bone cement.4 Correlation of BMD,insertion torque and pull-out strengths of pedicle screws.5 Ascertain whether augmentation with PMMA bone cement can enhance pedicle screw fixation in the osteoporotic spine.6 Ascertain whether augmentation pedicle screw fixation with PMMA bone cement can enhance the stability of unstable thoracolurner burst fractures of osteoporotic spine.

目 的1、测试椎体压缩强度，分析强度与骨矿物质密度（bone mineral density，BMD）的相关关系。2、观察经皮椎体成形术后聚甲基丙烯酸甲脂（polymethylme- thacrylate，PMMA）骨水泥在椎体内的形态学分布及影像学表现。3、比较PMMA骨水泥骨质疏松椎体成形术前/后椎体最大抗压力和压缩刚度的变化。4、分析椎体BMD、螺钉最大旅入力矩和最大拔出力三者之间的关系。5、分析PMMA骨水泥强化骨质疏松椎弓根螺钉后的螺钉的最大轴向拔出力和拔出刚度的变化。6、评价PMMA骨水泥强化骨质疏松椎弓根螺钉脊柱内固定对不稳定型胸腰椎损伤的即刻稳定性和反复载荷后的稳定性。

According to this researcher, all these conclusions reveal that regular consumption of goat milk – a natural food with highly beneficial nutritional characteristics - has positive effects on mineral metabolism, recovery from ferropenic anaemia and bone mineralisation in rats.

根据这项研究，所有这些结论表明世界骨质疏松日，经常食用羊奶这一天然的、营养丰富的的乳品，对矿物质的新陈代谢后积极的影响世界骨质疏松日，帮助田鼠治愈了贫血和骨质疏松。
