1参考ICF分类确定脑卒中临床试验结局测量中的相关概念显示文摘目的使用ICF分类作为参考,系统地确定和量化脑卒中临床试验结局测量中的概念。方法根据预先制定的标准,从MEDLINE数据库中筛选1992~2001年间随机控制实验,提取结局测量,并将结局测量中的概念与ICF建立联系。结果在320个合格研究中,有160个(50%)随机样本。共确定148个健康状况测量指标。在11 283个提取的概念中,有91%的概念可与ICF分类建立联系。在各成分中最常使用的ICF类目是:属于活动与参与的d450步行(70%)、属于身体功能的d525排便功能(62%)和属于环境因素的e399支持和相互联系(30%)。结论ICF分类为确定及量化脑卒中临床治疗结局测量中的概念提供了有用的参考价值;脑卒中结局测量涉及大量概念,对于研究结果的可比性而言,测量内容的一致性是必要的。Szilvia GEYH Thomas KURT Thomas BROCKOW Alarcos CIEZA Thomas EWERT Zaliha OMAR Karl-Ludwig RESCH 陈迪(译) 王朴(译) 邱卓英(审校) 吴弦光(审校) 2008中国康复理论与实践2008,14,12:8
2Segmentation and Tracking of Neural Stem Cell显示文摘In order to understand the development of stem cells into specialized mature cells it is necessary to study the growth of cells in culture. For this purpose it is very useful to have an efficient computerized cell tracking system. In this paper a prototype system for tracking neural stem cells in a sequence of images is described. In order to get reliable tracking results it is important to have good and robust segmentation of the cells. To achieve this we have implemented three levels of segmentation. The primary level, applied to all frames, is based on fuzzy threshold and watershed segmentation of a fuzzy gray weighted distance transformed image. The second level, applied to difficult frames where the first algorithm seems to have failed, is based on a fast geometric active contour model based on the level set algorithm. Finally, the automatic segmentation result on the crucial first frame can be interactively inspected and corrected. Visual inspection and correction can also be applied to other frames but this is generally not needed. For the tracking all cells are classified into inactive, active, dividing and clustered cells. Different algorithms are used to deal with the different cell categories. A special backtracking step is used to automatically correct for some common errors that appear in the initial forward tracking process.Ewert Bengtsson 2005Chinese Journal of Biomedical Engineering(English Edition)2005,14,3:3
