SVM is a newly developed method based on statistical learning theory, and is widely used in non-linear function regression.

支持向量机是近年发展起来的一种基于统计学习理论的学习机器，在非线性函数回归估计方面有很多的应用。

In previous studies, Cyclooxygenase-2(COX-2) is believed to be linked with inflammations and tumors. But in recent reports, COX-2 is found to play important roles in osteoblastic mechanotransduction and in bone remodification and resorptions in some ways. It was found that mechanical stretches, such as hydrostatic forces and pulsating fluid flow, could increase the expressions of COX-2 mRNA and then prostaglandins, and activate many signal pathways in osteoblasts.

环氧合酶-2(cyclooxygenase-2，COX-2)以往被认为与炎症、肿瘤等有密切关系，近年研究发现它在骨骼重建、骨质吸收以及成骨细胞力学信号转导中发挥着重要作用，主要表现为机械牵拉、流体力、节律性液体流(pulsating fluid flow，PFF)等机械刺激均能引起成骨细胞COX-2高水平表达，进而引起前列腺素(prostaglandins，PGs)量的增加，激活成骨细胞内多条信号传导通路。
