成骨

Results SBR has better biocompatibility, which can effectively accele- rate the reconstruction of bone defects and help the new bone by being compounded with autogenetic bone.

骨髓细胞很容易在该材料表面黏附，自体骨的加入更有利于新骨长入材料的孔隙中，分化增殖，形成骨基质，并钙化成熟。

Furthermore, cell culture and amplification are comparatively easy so we can get a great quantity of cells applied by autografting and allografting.

目的：探讨由脂肪组织分离获得脂肪基质细胞的方法及其在体外经诱导培养后向成骨细胞分化的潜能。

Then, under the control of systemic factors, mesenchymal cells aggregate and differentiate to form catilage blastemal elements that prefigure skeletal limb components.

脊椎动物胚胎期骨与关节系统的发生是一种复杂生命现象，起始于中胚层间充质细胞的定向聚集，形成肢芽，然后在一系列作用因子的调控下，肢芽内细胞进一步分化，形成具有骨骼雏形的软骨原基，后者经软骨内骨化发育成骨。

Methods: 12 fresh frozen adult leg-foot specimens were mounted in a coordinated system, a Steinmann pin was perforated across the calcaneus, cuboidcum, talus, and naviculare as markers. The displacements of the marked points in the coordinated system were recorded. Through matrix translation and Euler equation, the rotational angle of the calcaneus, cuboideum, talus, naviculare were calculated, which represented the motion of the calcaneocuboid, talonavicular and ankle joint in different condition respectively, while statistical analysis were also taken between different conditions.

取新鲜足标本12例，通过加载使足产生某种形式的运动，用三维数字化坐标仪测量距下关节组成骨在某种运动状态下的相对三维坐标位移，通过矩阵转换和求解非线性函数方程计算其三维旋转角度，确定距下关节的运动范围、规律和在足整体运动中的作用。

Calcified rheumatic valve neoangiogenesis is associated with vascular endothelial growth factor expression and osteoblast-like bone formation.

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
