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。

一种用于基因表达谱分析的基因芯片方法

目的：通过研究SLE患者外周血基因表达谱的改变，建立一种新型的基因芯片技术用于分子发病机理的研究。方法：提取总RNA，逆转录合成单链cDNA、双链cDNA，体外转录合成生物标记的cRNA与基因芯片进行杂交，通过抗体的检测标记荧光染料Cy3，基因芯片扫描仪进行图像扫描。结果：该方法有较高的重复性和稳定性，SLE患者与正常对照组相比较，鉴定出94个基因存在表达差异。结论：该方法能在较少起始标本量的情况下，有效地进行SLE致病基因的筛选，更好的理解SLE发生的分子机理，并且可在其它疾病研究中推广应用。     

Anaesthesia monitoring: the human factors component of technology transfer

Resistance to change in monitoring practices from within the anaesthesiology community is a formidable obstacle, and coercive and exhortatory solutions are likely to be unsuccessful in some situations. An analysis of publications about technology transfer and professional obsolescence, and application of this data to the practice of anaesthesia, reveals various stresses that technology transfer from research areas to the workplace may induce in vulnerable anaesthesiologists and account for their attitudes. It is suggested that the invaluable pronouncements of high profile anaesthesiologist groups must be supplemented by supportive behaviour by physicians and administrators at an institutional level. The human factors issues to be addressed include: (i) Monitored data acquisition skills. (ii) Possibility of acting on monitored data. (iii) Assistance for personal insight into attitudinal difficulties that may be encountered. (iv) Data supporting the value of the device. (v) Ergonomically effective integration of the monitor into the work station.Alternatively the perceptions of potential users may accurately reflect changes in their status in the new work situation created by monitors, and decision making aids that may or may not be derived from them. Thus, plans to present job satisfaction in related clinical areas or to associate the proposed new system with evaluation of its effect on patient outcome will be necessary. In this way the clinician becomes involved in clinical research, a quality of personal and quality care development.

Time after excision and temperature alter ex vivo tissue relaxation time measurements

Previously unreported effects of tissue storage were recently observed in the authors' experimental magnetic resonance (MR) studies. To evaluate the effect of elapsed time after excision and storage temperature on tissue relaxation time measurements, tissue samples from the liver, pancreas, kidney, testis, spleen, and brain were obtained in rats. T1 and T2 were first measured within 5 minutes of excision, and between subsequent measurements, tubes were kept in a water bath at 40°C, at room temperature (28°C), or in an ice bath (4°C). Cellular and organellar integrity was assessed with electron microscopy and correlated with the MR findings. At 40°C (20-MHz spectrometer), the T1 of liver decreased from 280 msec ± 8 to 212 msec ± 10 during the first 60 minutes; the T1 of pancreas decreased from 276 msec ± 3 to 208 msec ± 2. Other tissues showed less than a 5% decrease in T1. T2 changes were smaller than T1 changes in all tissues. Electron microscopy of pancreatic acinar cells showed postmortem changes in mitochondria evolving over the first 60 minutes after death. Manganese loading experiments implicated mitochondrial manganese stores in the observed enhanced postmortem decrease in T1. This study calls into question reported relaxation time data for liver and pancreas. MR studies of excised tissues must account for time and temperature to prevent systematic experimental errors.     

引导科技干部保持医院发展转型期间和谐心态的着力点

当前部队医院正处于发展转型期，如何引导科技干部适应转型发展新形势，经受住各种考验，始终保持理性平和、协调平衡、积极向上的心理状态，是一个不容忽视的现实问题，也是事关医院内部和谐和医院建设发展又好又快的大事，更是我们思想政治工作者必须着力认真研究、加以解决的重要课题。     

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.
