基质金属蛋白酶与肺癌转移的关系

基质金属蛋白酶(matrix metalloproteinases，MMPs)是一组锌离子依赖的蛋白水解酶，在ECM降解中起着重要作用。目前研究表明，MMPs活性异常不仅能促进肿瘤血管形成，还是人类多种肿瘤侵袭和转移的必要条件。本文就与肺癌侵袭和转移有关的MMPs研究作一综述。     

Self-directed learning in anatomy: incorporation of case-based studies into a conventional medical curriculum

This paper reports an attempt to develop self-directed learning skills in second-year medical students by introducing case-based projects into the gross anatomy course at a long-established medical school. The programme and students' responses to a questionnaire completed at the end of the year are presented. Information on the various resources used by students to find information is given. The performance of students in the case-based components of the course has been evaluated and also in the more traditional end-of-year written examination. The data confirm that students have recognized that the projects were about obtaining a deeper understanding of the anatomy, and the programme appears to have promoted the use and study of library texts.     

Clinical Evaluation of a New Type of Centrifugal Pump

Abstract: The major problems with existing centrifugal pumps are leakage, mechanical trauma, and thrombus formation. In consideration of these problems, a new compact centrifugal pump system was developed. The purpose of this study was to evaluate the new centrifugal pump system clinically. Ten patients underwent open heart surgery with a centrifugal pump or a roller pump. During surgery, hemodynamic and hematological data were obtained. A pulsatile assist device in the pump circuit was used in patients with severe heart disease. There was neither operative death nor hospital mortality, and there was no difference with regard to hemodynamic data between the two groups. The centrifugal pump group, however, had significantly lower hemolysis, especially during prolonged cardiopulmonary bypass. This centrifugal pump could also create sufficient pulsatile flow with a pulsatile assist device. Postoperative macroscopic and microscopic findings demonstrated the smooth surface of the pump without thrombus formation. This centrifugal pump system might be useful for prolonged cardiopulmonary bypass.

2002～2006年广西大专新生乙肝病毒携带率观察

[目的]观察2002～2006年广西大专新生乙肝病毒携带率分布,为进一步防治乙型肝炎提供理论依据。[方法]收集2002～2006年大专新生入学体检资料,采用SPSS13.0软件进行整理、统计分析。[结果]2002～2006年5年中广西大专新生HBV携带率呈明显下降的趋势,平均每年以10%的速度下降,2006年乙肝病毒携带率比2002年下降了44%,尤其以2005年桂东南汉、壮民族下降最为显著。[结论]80年代中期广西普遍接种乙肝疫苗以后,乙肝疫苗阻断乙型病毒性肝炎在广西青少年母婴传播及水平传播效果已经显现。建议在广西各地区,尤其是在桂西北少数民族地区进一步加强乙型肝炎基因工程疫苗的接种工作力度,使乙型病毒性肝炎感染率控制到更低的水平。     

医疗设备管理面临的新挑战

目前,医疗服务价格的调整特别是大型医疗设备的检查费用下调和高值耗材附加收费的封顶限制及药品加成的即将取消,在一定程度上减轻了患者的经济负担,但同时也造成医院收入大幅下降。作为设备管理部门,如何从医疗设备配置和管理等方面来引导、配合事关医院生存和患者福祉的医疗服务结构调整,是新形势下的新挑战。通过探讨提出从严格控制医疗设备购置费用、优化医疗设备配置、保证常规医疗设备和提高管理水平等4个方面争取找到一条使病患和医院双方共赢的道路。     

Creating a place for population health: Interpreting the spaces of a new School in Auckland,New Zealand

Although the reconfiguring of health care within the hospital sector has gained considerable attention by social scientists, the tertiary education sector's response to new health philosophies and practices has proceeded largely unexamined. This paper considers the new School of Population Health at the University of Auckland, accounts for its origins and considers the synergies between its design and workplace organisation. The results of a thematic analysis of narratives offered by 24 employees collected in 2004 are then presented. Findings suggest that the amassing of academics from a range of health-related backgrounds is advancing interdisciplinary dialogue even if the nature and purpose of population health remains unclear to some. A key concern of respondents was the openness of the workplace which encourages a collaborative atmosphere but also generates distraction. The degree to which conduct within the new building is perceived as regulated was also of concern. Place clearly matters in the story of the new School: the form of the building (featuring an architecture of openness) complements its function (generating new collaborations and creative thinking about health). However, the question of how ‘salutogenic’ a setting it is remains contested.

胸腰椎前路手术的新入路

目的：介绍一种胸腰椎前路手术的新入路。方法：通过横突前，沿横突、椎弓根和椎体腰部，严格的从骨膜下向前剥离，直达前纵韧带下方。结果：经155例临床应用，这种新入路，不需要结扎节段血管，切口短、出血少、缩短了手术时间。结论：手术方法简单、操作技术方便，比原来的腹膜后入路损伤小，也同样达到理想暴露的目的。
