医院内肺部真菌感染的临床分析

目的:引起临床医师对医院内肺部真菌感染(PFIH)的高度重视.方法:对56例医院内肺部真菌感染的病例进行临床分析.结果:45例患者均患有慢性肺部疾病,其中以慢性阻塞性肺病、慢性肺原性心脏病导致的PFIH最多占68%.住院日的延长,广谱、多种抗生素的长时间应用,糖皮质激素和免疫抑制剂的使用,是PFIH常见的医源性因素.痰培养念珠菌属占91%,特别是白色念珠菌即占82%.结论:应尽可能减少或避免导致PFI

低重复率稿件中的学术不端行为检测与防范

重复率低却存在抄袭的稿件,其原因可能为单一的检测系统存在漏洞,新发表的论文上传数据库存在时间差,作者对稿件的有意识“修饰”,以及网络时代造假手段多样化.为此,文中提出以下措施:使用多种数据库进行文字检测,从查重报告中发现问题,建立有效的审稿专家数据库、网站教育和警示,充分利用网络资源,加快稿件处理进程,增强编辑的责任意识等,以利于更好地防范学术不端行为.     

植物生长调节剂在作物生产中的安全使用

植物生长调节剂已广泛应用于农作物生产中，能有效改善作物生长状况，提高产品产量和品质，但使用不当也会造成严重的药害。在实际生产中要注意安全使用植物生长调节剂，根据作物品种和使用目标，来选择植物生长调节剂的类型，严格控制浓度及施用方法、时间和次数，从而充分发挥植物生长调节剂的效果。

交通事故再现教学素材库的构建

以交通事故综合研究平台为依托建立的交通事故再现教学素材库，是一个融合汽车碰撞事故再现的基本理论与实践应用技术、事故人-车-路信息、事故现场和车辆图片、事故过程动画演示、事故案例数据库的综合软件平台。素材库包含6个相关部分：PPT课件库、事故案例库、事故图片库、再现演示库、资料库和论文库。相应课件和案例演示已在车辆工程专业相关课程中发挥作用。该素材库已多次应用于北京市交管部门事故办案民警的培训课程。     

环境中氡及其子体的危害与防治

氡是自然界中广泛存在的一种天然放射性气体,是人居环境中最直接的污染物,其危害是看不见、摸不着的,氡及其子体是铀、钍等放射性元素产物,是引发肺癌的重要致病因子,氡对人体的辐射伤害占人体所受到的全部环境辐射的55%以上,长期受到氡辐射,会导致肺癌、白血病、皮肤癌及其它呼吸道病变的产生。因此国内外科技界也越来越关注氡的辐射问题,为提高空气品质,保护人体免受辐射危害,本文重点介绍了氡的物理化学性质、环境中氡的来源及浓度水平、各种建筑材料中放射性核素的含量,讨论了通风对室内氡水平的影响,认为依靠住宅建筑和装修完成后的补救措施来防治室内氡危害的效能是有限的,防治室内氡危害的关键措施是从源头上减少氡的来源。

Eating disorder prevention initiatives for athletes: A review

A substantial amount of evidence suggests that collegiate and elite athletes involved in weight-sensitive sports are at greater risk of developing eating disorders (EDs) than the general population. With the limited effectiveness of treatment for EDs, prevention of EDs has been broadly considered in the literature. The present paper reviewed the existing literature on ED prevention programmes for athletes in order to determine the current status of prevention programmes and recommend future directions. The available literature suggests that selective, primary interventions with multiple targets and an interactive multimodal approach appear most effective. Current challenges in the field, including lack of longitudinal research, hesitation by the sport community to be involved in ED research and poor cross-field communication and collaboration, are also explored. The lack of dissemination of evidence-based prevention programmes and the simultaneous promotion of prevention programmes that have not yet been empirically examined are also discussed. Based on these observations future directions are recommended.     

First-rib stress fracture in two adolescent swimmers: a case report

First-rib stress fractures have been described in adolescent athletes in various sports, with only one prior case report of first-rib stress fractures in an adolescent female swimmer. There is a need for research on the cause, management, and prevention of these injuries as they lead to significant morbidity and critical time away from sport for these aspiring athletes. We aimed to describe first-rib stress fractures as a potential cause for non-specific atraumatic chronic shoulder pain in adolescent swimmers and to discuss the different presentations, unique risk factors, treatment, and potential injury prevention strategies of such fractures. We discussed two such cases which were successfully treated with activity modification with restriction of all overhead activity, gradually progressive physical therapy and a return to swimming protocol. First-rib stress fractures can vary in presentation and should be in the differential diagnosis in adolescent swimmers with chronic shoulder pain. These injuries can be successfully managed with rest from overhead activities and physical therapy. Gradual return to competitive swimming can be achieved even with non-union of a first-rib stress fracture. Emphasis on balanced strength training in different muscle groups and proper swimming technique is essential to prevent these injuries.
