Bricolage in action: learning about,making sense of,and discussing,issues about genetically modified crops and food

Making sense of new technologies and their associated risks entails lay people in utilizing various modes of reasoning and making use of a range of interpretative resources at hand to interrogate evidence. Such sense making is accomplished collectively in ways that are sometimes playfully inventive, and which have regard to ideas of accountability and morally acceptability. In practice, such bricolage-like processes appear to have certain similarities with the work of everyday scientific investigation. This paper examines these processes of lay practical reasoning by adopting an analytic stance that is concerned with examining the fine detail of what people demonstrably do in accomplishing such work. It draws on data generated by number of reconvened discussion groups, which formed a component part of the recent public debate in the UK about the possible commercialization of genetically modified crops.     

新型农村合作医疗实施前后住院卫生服务利用变化研究

目的:通过对新型农村合作医疗实施前后,试点县与非试点县农民住院卫生服务利用的对比分析,评价新型农村合作医疗的实施效果,为改善新农合试点县农民的卫生服务状况提供科学依据和政策建议。方法:资料来自卫生服务调查和卫生统计报表,对资料进行描述性分析和对比分析。结果:新农合实施前农民住院率为2.70%;实施后农民住院率为3.35%;新农合实施前农民未住院率51.51%;实施后未住院率25.80%。结论:新农合制度运行一年多来,住院率有了明显的提高,未住院率有了明显的降低。农民卫生服务利用得到了提高。     

医学发展趋势对中医药现代化的影响

本文从健康观念、医学模式、医疗模式等角度,探讨了医学发展趋势对中医药现代化的影响。认为生命的复杂性是现代医学发展与中医药现代化的交汇点。提出医学的发展和医学体系的完善,需要中、西医两大医疗体系的优势互补、相互渗透与交叉融合。中医药现代化可望为创建具有中国特色的新医药学,形成一个在医学上具有现代人文思想和兼容传统与现代医学优势,在药学上强调整体疗效与安全性,物质基础作用机理清楚的“未来新医药学”基础。     

激动M_3受体对间隙连接蛋白43表达的影响

目的探索激动心肌M3受体后间隙连接蛋白43的变化情况,进一步发现M3受体作为抗心律失常药物作用新靶点的作用机制。方法通过免疫组化、划痕标记荧光传输技术结合激光共聚焦显微镜和RT-PCR的方法,研究激动M3受体对间隙连接蛋白43表达的影响。结果证实激动M3受体可以改善细胞和细胞之间的通讯,改善病理条件下间隙连接蛋白43的重构,且其磷酸化水平在间隙连接蛋白的重构过程中发挥了重要作用,并且还发现激动M3受体可以恢复病理条件下下降的间隙连接蛋白43的mRNA水平。结论激动M3受体可以改善病理条件下间隙连接蛋白43的重构,并且其磷酸化形式在闰盘重构中发挥重要的作用。     

凤阳县新型农村合作医疗住院病人费用分析

凤阳县作为新型农村合作医疗的首批试点县,从2003年始已实施了近四个年头.现依据医院信息资料作统计对比,分析新农合试点前后病人的平均住院费用有显著差别,试点前的人均住院费用高于试点后.单病种费用的横向对比结果表明,参合与非参合的平均医疗费用无明显差别.     

互助医疗与新型农村合作医疗缓解"因病致贫"的效果比较

目的:比较新型农村合作医疗和农村互助医疗2种医疗保障制度在缓解卫生服务利用人群"因病致贫、因病返贫"方面的效果。方法:资料来源于2005年11月对陕西省镇安县高峰镇和铁厂镇的入户调查数据和样本人群医疗服务利用报表数据,贫困测量指标选用贫困发生率、贫困距指数、收入差距比率、森的贫困指数、补偿资金的使用效率和供给率。结果:农村互助医疗制度缓解卫生服务利用人群"因病致贫"的效果好于新型农村合作医疗制度。建议:新型农村合作医疗制度取消门诊个人账户,对住院和门诊服务利用均进行一定程度的补偿。     

HPLC同时测定复方氯霉素乳膏中氯霉素和醋酸地塞米松的含量

目的:建立高效液相色谱法测定复方氯霉素乳膏(新复霜)中氯霉素和醋酸地塞米松的含量。方法:用十八烷基硅烷键合硅胶为填充剂[Symmetry C_(18)柱(4.6 mm×150 mm,5 μm)];以甲醇-水(64∶36)为流动相,流速为0.5 mL·min~(-1);检测波长为240 nm;进样量5 μL。结果:氯霉素及醋酸地塞米松在231.3～809.5μg·mL~(-1)(r=0.9999)和14.1～84.6μg·mL~(-1)(r=0.9999)范围内呈良好的线性关系;氯霉素和醋酸地塞米松精密度 RSD 分别为0.16%和0.22%;平均回收率(n=9)分别为100.1%和99.55%。结论:本方法快速、简便,重现性好,结果可靠,可作为复方氯霉素乳膏的质量控制标准。     

新课程标准下的高校体育教育改革趋势探讨

课程改革是基础教育改革的核心内容,而体育课程(小学)和体育与健康课程(中学)是中小学课程体系中的一个重要组成部分,是实施素质教育和培养德、智、体、美全面发展人才所不可缺少的重要途径,本文就新的体育课程标准下,高校体育教育改革趋势作一些初步的探析,其目的是为了进一步深化高校体育教育改革,为高师培养适应我国21世纪社会主义现代化建设的高素质的人才发挥重要作用.

Electron microscopic features of an experimentally produced porencephalic cyst in the rat brain

Summary Needle injury of the newborn rat brain resulted regularly in cavity formation, the lining of which at first consisted of a layer of fibrous astrocytes with many thin cytoplasmic projections. Between the second and third weeks the astrocytic surface became smoother and was lined by a basement membrane, usually in association with an overlying layer of pia-like cells. Only after this time did the fine structure of the cavity wall resemble that of Held's membrana gliae limitans superficialis. It is, therefore, suggested that Spatz's membrana gliae limitans accessoria be reserved for this differentiated structure and not used to identify the earlier astrocytic lining. No dense glial or connective tissue scarring, as usually seen in the adult brain, was found. Macrophages disappear before the third week, rather than persisting for months, as in the adult. The presence or absence of scar formation and macrophages may only reflect the age at which the injury occurred and may, therefore, be unreliable in distinguishing between cavities due to malformation and to injury.The authors wish to acknowledge the technical assistance of MissesEvi Eichhorn, Doris Höna, andSusanne Luh.
