The results showed that steroid potentiates hypercoagulable and hypofibrinolytic states which would play an important role in inducing and developing osteonecrosis, these might cause IC, forming intraosseous thrombi, which would further cause ischemia of bone marrow and bone, thus result in osteonecrosis.

这表明激素助长了高凝和纤溶下降状态，高凝和纤溶下降在激素性骨坏死发生发展中起重要作用，二者异常引起骨内IC，形成骨内血栓，引起骨缺血乃至骨坏死。

It is one of the key pathogeneses of postmenapausal osteoporosis that estrogen deficiency leads to the decrease of OPG、TGFβ expression and the increasing expression of some bone-resorbing cytokines as OPGL、M-CSF and TRAIL, then stimulates osteoclast differentiation and activity, which potentiates bone resorption and bone loss:(2) ICI182780 shows partial transactivating function in osteoblasts, so it should belong to a kind of selective estrogen receptor modulators .

雌激素缺乏可能导致HOB中OPG、TGFβ的表达减少，而解除了对OPGL、M-CSF和TRAIL等刺激OC生成和活化的细胞因子的抑制作用，OC的数量和活性增加，导致骨吸收增强和骨量丢失，这是导致绝经后骨质疏松症的一个重要的发病机制；ICI182780在成骨细胞内表现出促转录活性，因此它并非纯ER拮抗剂，而应属于选择性雌激素受体调节剂(selective estrogen receptor modulator，SERM)。

Effects of pulsing electromagnetic fields with different wave forms on proliferation of osteoblasts.

不同脉冲波电磁场对成骨细胞增殖的作用。

We found that osteoblasts expand rapidly after cyclophosphamide/G-CSF treatment and exhibit phenotypic and functional changes that directly influence HSC proliferation and maintenance of reconstituting potential.

我们发现经过G-CS处理后成骨细胞扩增迅速，表现出表型，功能发生改变，直接影响HSC扩增和保持重塑潜能。

However, the mechanism how PDL cells transform mechanical signals into the activity of bone remodelling has been unclear.

但是正畸过程中牙周膜细胞受机械力后如何将力信号转化为成骨及破骨活动的机理至今仍不清楚。

RANK ligand has been shown in preious studies to be an important inflammatory protein that can lead to bone loss through actiation of bone resorbing cells.

而这个RANK配基在目前的研究中被认为是有一个重要的炎症蛋白质，它会激活骨吸收细胞而造成骨丢失。

Results The sandblasting and the SLA surface showed a significant different to smooth surface in the proliferation osteoblasts.

结论喷砂并酸蚀处理的新型钛合金在体外实验表现为不同程度的促进成骨细胞增殖及功能活性表达。

The detailed investigates of osteoblast response to varied surface topographies might be essential to overcome the problem of bone-implant interface.

为解决骨组织－金属材料的界面问题，必须充分理解金属材料不同表面形态对成骨细胞生物学行为的影响。

Disorderly orientation and a age of the collagen structure of trabeculae were manifested.

大量功能活跃的破骨细胞出现，成骨细胞功能相对减退，向骨细胞转化。

In the period of 8 to 16 weeks after operation,new bone was formed continuously, artificial bone gradually reconstructed to mature lamellar bone,bone trabeculae and medullary cavity,etc. Conclusion The preparation of CPC is simple.

结果 CPC植入后4周有新生软骨形成及未成熟的骨组织，可见大量的软骨细胞、成骨细胞、胶原组织及较多的小血管。8～16周新骨继续生成，人工骨逐渐改建为成熟的板层骨、骨小梁和髓腔结构。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
