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.

地方性氟中毒家猪胫骨形态计量学的初步研究

本文应用 Mop-Videoplan 图象分析仪对氟中毒家猪胫骨进行了骨计量学的初步研究。四环素双标记后将家猪胫骨制备成骨磨片,在荧光及普通光学显微镜下测量了一系列骨计量学参数。结果表明,氟中毒导致家猪胫骨髓腔面皮质新骨体积明显增加,但其增加程度不与血氟呈正相关。新骨体积增加可能是造成临床 X 线氟骨症表现骨髓腔狭窄的原因。骨动力学研完表明,氟中毒造成四环素双标记明显减少,这可能与氟抑制骨组织的转换过程有关。     

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。

三峡建坝后血吸虫病传播危险因素研究Ⅲ库区血吸虫病监测方案的研究

目的了解三峡库区血吸虫病传播危险因素,为三峡库区血吸虫病动态监测提供技术方案。方法在三峡库区进行钉螺生存模拟试验,调查库区流动人口、家畜血吸虫病传染源和钉螺输入库区的潜在危险因素,以及建坝后社会经济发展变化对血吸虫病传播的潜在影响因素,找出库区血吸虫病监测的重点。结果钉螺在三峡库区的适宜环境中能够生长繁殖;血吸虫病传染源主要是往返于血吸虫病流行区的流动人口;从血吸虫病疫区引进花草树木和牲畜,存在将钉螺和动物传染源输入库区的可能;库区社会经济发展可使血吸虫病传入的危险增加,三峡库区已成为血吸虫病的潜在流行区。结论三峡库区血吸虫病监测工作重点应是流动人口、引进的牲畜等血吸虫病传染源和钉螺输入因素的监测。     

HTLV-I, HIV-I, and Hepatitis B and C Viruses in Western Province, Papua New Guinea: A Serological Survey

Seven hundred and twenty-three serum samples from individuals in 13 Gidra-speaking villages in Western Province, Papua New Guinea were tested for evidence of infection with human T- lymphotropic virus type I (HTLV-I), human immunodeficiency virus type I (HIV-I), hepatitis B virus (HBV) and hepatitis C virus (HCV). No samples were positive for antibodies to HIV-I. Antibodies to HTLV-I were found in 13 samples (1.8%), HBV surface antigens (HBsAg) were found in 86 samples (11.9%), and antibodies to HCV were found in 30 samples (4.1%). Six (46.2%) of 13 HTLV-I positive samples were positive for HCV or HBsAg. The seropositive rate varied in different villages and the incidence of HTLV-I and HCV was higher in coastal and riverine areas than inland.     

Efficacy I: a new method for estimating relative efficacy of full agonists via a newly defined efficacy related parameter

A new method for estimating relative efficacies and relative intrinsic efficacies of agonists is described. Relative efficacy is estimated by employing a newly defined efficacy related parameter (e^ES) and it may be estimated without prior knowledge of efficacy values or the value of the equilibrium dissociation constants, K_A, of agonist-receptor complexes. The parameter e^ES is directly related to efficacy (e) and is defined as the ratio of maximal stimulus to maximal effect of an agonist. The value of e^ES indicates whether or not spare receptors are present for a particular agonist–effector system. The e^ES values of agonists are estimated by utilizing submaximal concentration–effect curves determined with fixed agonist-competitive antagonist concentration combinations and choosing a suitable reference (height of an agonistic concentration–effect curve) to which the height of the stimulus concentration–effect curves of the agonist may be compared. In addition to e^ES, other new agonist–effector parameters, namely S_Em/S_m and φ_min, were also defined.
