BACKGROUND: Under different induction conditions, bone marrow mesenchymal stem cells can differentiate into the mesodermal tissues such as osteoblasts, chondroblasts, muscle cells, adipocytes and so on.

背景：骨髓间充质干细胞在不同诱导条件下具有向中胚层组织细胞如成骨细胞、成软骨细胞、肌细胞、脂肪细胞等分化的能力。

Objective: This paper evaluates the effect of distraction osteogenesis in treatment of mandibular micrognathia accompanying with obstructive sleep apnea hypopnea syndrome.

目的：探讨牵引成骨术在治疗小下颌畸形伴阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome， OSAHS)中的应用。

Reported the first clinical application of mandibular lengthening by gradual distraction in patients with hemifacial microsomia and Nagers'syndrome.

自从1992年，McCarthy等首先报道采用下颌骨逐渐牵引延长，以治疗半面萎缩和Nagers综合征以来，颌面部牵引成骨技术的研究已陆续开展起来。

We show that the Wnt signaling actiator 6-bromoindirubin-3'-monoxime releases MSCs from the osteoinhibitory effects of Dickkopf-1, whereas LiCl treatment does not.

我们也发现Wnt信号激活剂BIO会解除DDK1对MSC的成骨抑制作用，而LiCl处理则无这种作用。

Results D Cell morphology : Osteoblasts adhered tightly to five different titanium surface; On G surface, osteoblasts were spindle-shaped along the groove; Osteoblasts were cubic, multangular and abundant cytoplasm on SB surface and TPS surface, spreading in all directions.

①细胞粘附形态：成骨细胞在五种不同处理钛片表面粘附生长，SB组、TPS组表面细胞为多边形，胞浆丰富，有多个伪足突起呈分化表型；G组表面细胞胞体沿打磨沟嵴的方向伸展呈长梭形，少见伪足突起。

A line of osteoblasts is present a the center-right forming new bone, but lacunae containing multinucleate osteoclasts are at the center left and lower center destroying bone.

一行成骨细胞正在中右部形成新骨，而腔隙内的多核破骨细胞正在中左与中底部破坏骨。

To observe the effect of naringin solution on osteoblast line MC3T3E1 proliferation.

检测柚皮苷溶液对成骨细胞株MC3T3E1细胞增殖功能的影响。

Methods BMSCs isolated from rabbit iliac bone marrow were culture-expanded in vitro. The injectable tissue-engineered bone constructed from autologous PRP, FG, and BMSCs was cultured in vitro, and its biological characteristics were observed including the time of gel formation, histological features, seed cell survival and microscopic structures. Results The constructed injectable tissue-engineered bone began gel formation within 20 to 30 s, and after a week-long culture, the gelatine began to degrade, and numerous well viable fusiform cells could be seen to adhere to the bottom of the Petil dish, Scanning electron microscopy identified globular and olivary cells embedded in the fibrin glue, and numerous small particles could be seen around of the cells.

从兔髂骨处抽取骨髓体外培养BMSCs并诱导向成骨细胞分化，抽取兔自体动脉血提取PRP，以FG、BMSCs、PRP共同构建可注射型组织下程骨并体外培养观察其生物学特性如凝胶形成时间，组织学特点、细胞存活情况及其超微结构特征等结果构建的可注射型组织工程骨可在短时间内形成凝胶，体外培养1周时其中细胞生长良好，电镜下见纤维蛋白网格结构致密，种子细胞及血小板颗粒分布广泛。

MAIN OUTCOME MEASURES: In vivo degradation performance and ossific capability of PHBV copolymer as well as energy-dispersive X-ray analysis and elemental quantitative assay in bone defect regions.

主要观察指标：①聚羟基丁酸/羟基戊酸共聚酯的体内降解性能和成骨能力。②骨缺损区X射线能谱分析及元素定量测定。

OBJECTIVE: To investigate the proliferation and osteoblastic differentiation of adipose-derived stem cells induced by calcitonin gene-related peptide in vitro.

目的：探讨降钙素基因相关肽在体外定向诱导脂肪干细胞向成骨细胞增殖分化的可行性。

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）。
