滥用药物与生命质量退化的伦理思考

本文从生命质量的内涵入手,分析了滥用药物的直接和间接、近期和远期的危害,通过论证得出了滥用药物必将引起人类生命质量退化的结论.以期从一个新的认识度唤起人们对滥用药物问题的重视、并由此引出了一些对医学目的以及滥用药物控制措施的思考.     

Public health medicine and drinking water in Scotland

The prevention of the spread of disease by drinking water relies on a tripartate arrangement among the supplier, the regulator and their medical advisers. This paper describes the role of Public Health Medicine in Scotland in preventing a ‘significant risk to health’ from potable water. The legislative framework is highlighted. The rationale of water monitoring is examined and the role of Consultant in Public Health Medicine. The concept of Significant Medical Risk Values is introduced and their derivation, uses, and levels presented.     

明清时期新安药店及其医药学作用

新安药店始于宋，成于明，至清末一度达到鼎盛。较有代表的宋有“陆氏保和堂”，明有“徐保元堂”、“正田药店”、“胞与堂”等，清有“胡庆余堂”、“胡咸春”、“种德堂”等。这些药店明多为医家兼营，清多为徽商经营。新安药店作为集医疗、生产、经营一体的传统手工业，至今不少成为著名药厂，如“武汉健民制药厂”、“胡庆余堂”等。其在生产、经营、管理上积累了许多经验，同时在方剂学以及药物炮炙、贮藏、采集、加工、成方制作等方面皆有不少成就。     

应用地理信息系统分析中国肾综合征出血热的空间分布

目的　利用地理信息系统 (GIS)技术分析中国大陆肾综合征出血热 (HFRS)的空间区域分布 ,建立HFRS危险区域分布图。方法　收集中国 41个HFRS监测点 1 995～ 1 998年的人群发病资料建立数据库 ,以中国省级、县级、一级河流数字地图为背景 ,在ArcGIS软件的支持下 ,与建立的数据库关联并对监测点人群发病资料进行反距离权重插值分析 ;收集 1 998年 6月SPOT4卫星覆盖东南亚地区的植被影像 ,逐一提取出各监测点监测区域的归一化植被指数 (NDVI) ,与 1 995～ 1 998年HFRS监测点人群平均发病率进行相关分析 ;根据不同流行强度监测区域的NDVI值 ,对遥感影像使用不同的颜色进行密度分割。结果　HFRS监测点人群发病资料的空间分析预测模型显示 ,中国HFRS主要分布于黑龙江流域、黄河中下游地区、长江中下游地区及京杭大运河 淮河流域地区 ,与1 995～ 1 998年全国各县HFRS平均发病率分布图进行比较 ,发现两者基本一致 ;相关分析显示HFRS发病率与NDVI之间呈现正相关 (r=0 .41 7,P <0 .0 1 ) ,根据各监测点NDVI的差异建立了中国HFRS危险区域分布图。结论　根据监测点数据采用GIS技术建立的预测模型对预测全国HFRS的分布情况有重要意义     

Heparin effect on ionised calcium concentration

The effect of heparin on plasma ionised calcium was studied by adding it in increasing amounts to whole blood from 10 normal subjects. There was no significant change in ionised calcium from the addition of 1 U/ml but a significant fall of 0.02 mmol/1 when 2 U/ml were added and a progressive further fall with increasing concentrations. Heparin from three different manufacturers produced similar results. The effect of heparinisation in vivo was studied during regular haemodialysis on 10 patients with chronic renal failure. Following intravenous injection of 10000 U of heparin there was a consistent and significant fall averaging 0.03 mmol/l.     

刘嘉湘教授辨治肝癌经验

辨治肝癌，依据肝脏的生理特点及肝癌的病理变化遣方用药。肝喜疏泄条达而恶抑郁，疏通气血是刘师治疗肝癌的基本法则。由于肝癌发生的实质在于肝脏的阴阳失去平衡，治疗的目的在于调和阴阳。临床上需根据疾病的症状及发展的不同阶段，采取补肝益气法、健脾理气法或养阴柔肝法，兼以解毒利湿、化瘀散结，达到补泻结合，取效良好     

中医中药治疗胃脘痛120例临床观察

运用中医中药辨证治疗胃脘痛120例,分为肝郁气滞、脾胃气虚和阴虚郁热三个证型,分别采用疏肝理气,健脾和胃及滋阴清热等方法治疗,总有效率达94.7%.经统计学处理,对肝郁气滞型疗效最好,与脾胃气虚型相比有一定差异,与阴虚郁热型相比有显著差异(P<0.05);阴虚郁热型疗效最羞,与脾胃气虚型相比有显著差异(P<0.05).     

What has trust got to do with it? Cardiac risk reduction and family physicians' discussions of evidence-based recommendations

The management of patients through the use of evidence-based medicine has become the 'mantra' of medicine within many Western countries. Evidence-based medicine is aimed at providing the best objective, scientific care to all patients, and reducing as far as possible patients' risks of disease and complications from disease. Based on family physicians' discussions of the use of evidence-based recommendations for two cardiac diseases, this paper explores how subjectively-based trust enters into family physicians' decision to use evidence-based medicine. In addition, we show how trust influences physicians' work of recommending evidence-based medicine to patients, and physicians' perceptions of why patients follow recommendations aimed at risk reduction. We conclude that although much of the current discussion about evidence-based medicine assumes a 'rational' model of physician behaviour based on the application of the 'best objective scientific' results, subjectively-based perceptions of trust influence physician practices, and point to the need to understand the power of relational issues in influencing physician practices even when utilizing evidence-based knowledge.
