Skeletal metastases result in significant morbidity and mortality.This is particularly true of cancers with a strong predilection for the bone,such as breast,prostate,and lung cancers.There is currently no reliable cure for skeletal metastasis,and palliative therapy options are limited.The Wnt signaling pathway has been found to play an integral role in the process of skeletal metastasis and may be an important clinical target.Several experimental models of skeletal metastasis have been used to find new biomarkers and test new treatments.In this review,we discuss pathologic process of bone metastasis,the roles of the Wnt signaling,and the available experimental models and treatments. Skeletal metastases result in significant morbidity and mortality. This is particularly true of cancers with a strong predilection for the bone, such as breast, prostate, and lung cancers. There is currently no reliable cure for skeletal metastasis, and palliative therapy options are are. The Wnt signaling pathway has been found to play an integral role in the process of skeletal metastasis and may be an important clinical target. Severral experimental models of skeletal metastasis have been used to find new biomarkers and test new treatments. In this review, we discuss pathologic process of bone metastasis, the roles of the Wnt signaling, and the available experimental models and treatments.

传统磁共振(MR)傅里叶成像方法由于傅里叶不确定性,k空间扩展编码采样长度能提高图像空间分辨率,但是以降低图像信噪比为代价。提出基于最大似然优化模型的各向异性约束MR成像新方法,将离散傅里叶变换模型改进为惩罚约束函数的最优值搜索问题。利用医学结构的先验信息,将正则化惩罚运算细化至平滑区域、边界邻域、边界和边界的方向。实验结果表明,该方法不但能扩展k空间高频数据采样长度同时有效降低高斯噪声,而且能克

点云中存在奇异情况时,采用最小生成树法进行法矢调整会出现错误,而采用曲面重建方法运算效率又较低,为此提出一种点云模型法矢调整的优化算法。算法分别处理薄壁特征、垂直法向和相邻曲面3种奇异情况。对薄壁特征,算法提取特征点并在该处强制进行法矢取反;对垂直法向,算法通过扩大邻域搜索范围来获得法矢变化趋势;对相邻曲面,算法在K邻域中剔除歧义邻域点,避免在最小生成树中生成错误边。实验结果表明,该算法在点云中存
