驾驶姿势不当引发的疾病和预防

长时间的汽车驾驶容易引起身体疲劳，若不注意驾驶姿势。则容易引发一系列疾病。驾驶姿势不正确容易引发如下疾病：     

纳米科学对疾病研究的新发展

纳米医学 美国密歇根大学的物理学家詹姆斯·贝克研制出了一些多用途的纳米粒子，它们能够穿越血管壁等障碍，接近癌细胞，让癌细胞误认为是可以吃的食物，它们会用荧光色对癌细胞进行标记，同时用药物把癌细胞摧毁。研究证明，这些纳米粒子杀死癌细胞的效果要比传统的化学疗法有效得多。该领域的研究是基于纳米技术的医学革命的最新进展。它们将彻底改变人类诊断和治疗癌症以及所有疾病的方式。有专家称，这项新技术代表着定位疗法发展的第二次浪潮，在未来几年会得到加速发展。[第一段]     

论新形势下疾病预防控制档案信息的开发利用

疾病预防控制部门担负着承担政府公共卫生职能、疾病预防控制、健康教育与促进等重任，在保护人民健康、维护社会稳定和促进经济发展等方面起着重要作用。疾病预防控制档案是指疾病预防控制机构在疾病预防、卫生学评价、公共卫生监测、卫生检验检测、健康促进与教育等活动中形成的具有保存价值的各种文字、图像以及其他不同形式的历史记录载体。其真实地记录着疾病预防控制机构的主要职能活动，     

高职高专开设眼视光技术专业的探讨

目前我国正处于近视高发期,眼镜市场的需求巨大，而相应的眼视光技术专业人才却很短缺。我国加入WTO和职业资格认证制度的实施，给高职高专医科院校开展眼视光技术职业教育带来了良好的机遇。     

关于新时期铁路疾病预防控制工作转型的探讨与思考

为探索新形势下铁路疾病预防控制工作的发展对策,从适应改革发展要求出发,以国家疾控体系建设规定为依归,结合铁路实际,突出行业特点,进行客观对比分析,从宏观的视角进行理性思考与探讨。认为铁路疾控工作面临转变观念、转变策略和转变职能的挑战。提出以发展应对挑战,以转型争取主动。建议从以传染病防治为主,向以慢性病防治为主转变,重新定位职能,强化服务意识,展示新作为,续写新辉煌。     

A data model applied to the knowledge-based ICAS

Image-guided computer aided surgery system (ICAS) contributes to safeness and success of surgery operations by means of displaying anatomical structures and showing correlative information to surgeons in the process of operation. Based on analysis of requirements for ICAS, a new concept of clinical knowledge-based ICAS was proposed. Designing a reasonable data structure model is essential for realizing this new concept. The traditional data structure is limited in expressing and reusing the clinical knowledge such as locating an anatomical object, topological relations of anatomical objects and correlative clinical attributes. A data structure model called mixed adjacency lists by octree-path-chain (MALOC) was outlined, which can combine patient's images with clinical knowledge, as well as efficiently locate the instrument and search the objects' information. The efficiency of data structures was analyzed and experimental results were given in comparison to other traditional data structures. The result of the nasal surgery experiment proves that MALOC is a proper model for clinical knowledge-based ICAS that has advantages in not only locating the operative instrument precisely but also proving surgeons with real-time operation-correlative information. It is shown that the clinical knowledge-based ICAS with MALOC model has advantages in terms of safety and success of surgical operations, and help in accurately locating the operative instrument and providing operation-correlative knowledge and information to surgeons in the process of operations.
