骨发生

Citric acid with calcium in the bone reaction, and softening of bone, bone oil熬出fat to bone.

However, the stress load alters in the proximal femur following THA, leading to "adaptable bone reconstruction", which is characterized by thin cortical bone, decreased bone density, and bone loss surrounding prosthesis, in particular calcar femorale.

但是全髋关节置换后股骨近端应力负荷会发生改变，导致股骨近端的所谓"适应性骨重建"，其特点是皮质骨变薄，骨密度下降，引起股骨近端假体周围，尤其是股骨距区骨丢失。

(1) The input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar, Abduction in small degree (10-30°) will improve the stress in femoral neck region. The stress distribution of the femur under extemal violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.(2) The finite element model of femoral neck fracture is good in orrowing various fixation methods for femoral neck fracture.

(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法，不仅能考虑到所研究物体的几何形状，而且也考虑到物体的内部结构特性；股骨颈处的压力骨小梁和股骨距是重要的承载结构，内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入；载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处；一定角度的下肢外展（10-30°）会较明显的增加股骨颈区的应力，而下肢的内收反而会减小此区的应力；暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

BACKGROUND: The silica gel prosthesis and os lenticulare were widely used as substitute for lunar bone, which can result in complications, such as periostitis, bone resorption as well as carpal bone collapse.

摘要背景：月骨切除后以往用硅胶假体和豆状骨移位等替代，短期有一定疗效，但可发生硅胶性骨膜炎、移植骨吸收和腕骨塌陷等并发症。

From the femur bone density analysis of protein expression, we can see that light chain lactoferrin, annexin decreased and the expression of enolase, ATP synthase, acetyl-coenzyme A reductase, the expression of troponin, may be related to ovariectomized femoral bone density in osteoporosis-related happened; strong bone of the femoral osteoporosis Po intervention effect may be related to reduced enolase, ATP synthase, troponin, CK-MB, acetyl phosphoglycerate enzyme, the expression of myosin, and the increase in lactoferrin light chain, pyruvate kinase isoenzyme, protein expression crown.

从股骨密质骨蛋白质组表达分析可知，乳铁蛋白轻链、膜联蛋白A3的表达下降及烯醇化酶、ATP合酶、乙酰辅酶A还原酶、肌钙蛋白的表达增强，可能与去卵巢后股骨密质骨骨质疏松的发生相关；强骨宝对股骨骨质疏松的干预效应可能与下调烯醇化酶、ATP合酶、肌钙蛋白、肌酸激酶同工酶、磷酸甘油酸变味酶、肌球蛋白的表达，和上调乳铁蛋白轻链、丙酮酸激酶同工酶、冠蛋白的表达有关。

Ameloblastic carcinoma is akind of rare malignant tumor of jaws.

造釉细胞癌是一种发生于颚骨内罕见的恶性肿瘤，尤其发生在上颚骨内者其恶性程度更大。

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。

The Results displayed: DChanges of histological morphology in treating group is superior to the other two groups.(2Expression of BMP-2 at fracture region in treating group is obviously supeior to the other two groups(p.05) and advancely reach peak valuce at first weak.(3) transcriptional level of BMP-2 mRNA in treating group is obviously supeior to the other two groups(p.05) and samely advancely reach peak valuce at first weak.(4)In every period of fracture healing, the expression of BMP-2 and transcriptional level of BMP-2 mRNA appear dynamic change and begin to go up after fracture, moreover reached to peak value in two weaks, then go down gradually.

结果发现：(1)治疗组组织形态学检查明显优于其它二组；(2)治疗组骨折部位骨形态发生蛋白-2(BMP-2)的表达水平比其它二组明显提高(P＜0.05)，并在一周时提前达到高峰；(3)治疗组骨折部位骨形态发生蛋白-2(BMP-2)mRNA的转录水平比其它二组明显提高(P＜0.05)，同样在一周时提前达到高峰；(4)在骨折愈合的不同时期，BMP-2的表达及其mRNA的转录水平呈动态变化，即骨折后开始升高，2周左右达到高峰，以后逐渐下降。

AIM: Bone morphogenetic protein as polyphenic morphogen can induce the formation of bone and cartilage.

目的：研究证实，骨形态发生蛋白是多效性的形态发生素，在一定环境下，可诱导骨与软骨的形成。

Objective To investigate the biomechanical behavior of injectable recombinant human bone morphogenetic protein-2 (rhBMP-2)/calcium phosphate cement used in vertebroplasty in primate models. Methods Two fresh cadavers of adult rhesus were used as group Ⅰ, and 4 adult rhesuses were divided into groups Ⅱ and Ⅲ.

复合重组人骨形态发生蛋白-2的可注射磷酸钙骨水泥在椎体成形术中的目的探讨自主研发的复合重组人骨形态发生蛋白－2(rhBMP-2)的可注射磷酸钙骨水泥应用于猕猴椎体成形术早期和后期生物力学性能。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
