How are nations trying to prevent suicide? An analysis of national suicide prevention strategies

Recent increases in suicide rates internationally have focused attention on suicide as an important area of public health concern. In this review, strategies developed by various countries to halt this trend are compared. Nine out of 15 countries respond to enquiry about the state of development of suicide prevention strategies and programmes. Comprehensive strategies have been or are being developed by Finland, Norway, Australia, New Zealand and Sweden. The organization of these strategies differs between countries. The interventions have similar targets and are presented in detail. There are some similarities in strategy content but evident differences in organization. Further developments should not only be based on research, but also consider the diverse experiences of other countries, and they should incorporate appropriate structures for monitoring and evaluation.     

呼吸道感染与气象因素的关系

呼吸道感染是呼吸系统常见病、多发病。利用杭州地区1990年1月～1992年12月气象资料作了统计分析，并对同期来海军杭州疗养院门诊就诊的呼吸道感染病人进行了调查。结果为1～3、11、12月发病率高，与5～9月相比有非常显著差异（P＜0．001），呼吸道感染与气温低，湿度高，温差大，天气骤变等气象因素密切相关。潮冷天气（气温在10℃以下），频繁降温（每月3次以上），大幅度降温（4℃以上）三种气象因素共同存在情况下可导致呼吸道感染性疾病的高发。同时从气象学角度提出了预防该病的一些措施。     

山莨菪碱防治甘油所致急性肾功能衰竭的实验研究

在１２９只ＳＤ大鼠的实验中动态观察了山莨菪碱对甘油所致急性肾功能衰竭时不同时期的Ｂｃｒ，ＢＵＮ，ｐＨ病理改变及死亡率的影响，结果表明：山莨菪碱能降低ＡＲＦ第５天大鼠死亡率以及Ｂｃｒ，ＢＵＮ水平。改善病理损害，对ＡＲＦ起到预防及治疗效果，山莨菪碱的预防效果优于治疗效果，预防是ＡＲＦ防治的关键，但山莨菪碱在治疗过程中要引起“冲刷综合征”导致洗脱性酸中毒，应引起注意。     

The callous elbow and aging of the upper arm

The author describes his surgical approach to the problems of the aging upper arm and elbow region. Surgery at an appropriate age can prevent the progressive wrinkling of the elbow which is further aggravated by aging of the upper arm. The author's operation is aimed at correcting both portions of the arm anatomy at the same time.     

几丁糖预防术后腹腔粘连的实验研究

目的探讨几丁糖对术后腹腔粘连的预防作用.方法将45只大鼠随机分为A、B、C 3组,于腹腔内浆膜损伤部位分别注入1%乳酸液、32%右旋糖酐-70液和2%几丁糖乳酸液各2 ml,术后14 d处死动物,观察各组腹腔粘连状况.结果 3组粘连分级比较有显著性差异(P＜0.01),C组粘连发生率与另2组有显著差异(P＜0.05).光镜下C组炎症反应轻微,纤维增生不明显;电镜下C组纤维细胞分泌胶原能力弱,间皮细胞增生活跃.结论几丁糖可有效降低大鼠术后腹腔粘连的发生和粘连程度,其作用优于右旋糖酐-70,且不影响切口的愈合.     

惠州市结核病控制项目实施效果评价

目的 总结我市结核病控制项目实施效果和经验。方法 根据全市各县(区)上报的结核病报表和有关总结材料进行分析。结果 在项目实施期间发现涂阳病人7522例，治愈了7303例，涂阳病人登记率从1993年的8．2／10万提高到2001年的39．4／10万，初、复治涂阳病人治愈率从1992年的80．0％和81．8％提高到2001年的98．9％和96．2％。结论 我市结核病控制项目实施效果显，项目所取得的成功经验和技术策略对今后结核病控制可持续发展有着重要的指导作用。     

Identification of antibacterial principles against Streptococcus mutans and inhibitory principles against glucosyltransferase from the seed of Areca catechu L

During the course of our studies on dental caries prevention by traditional medicines, fatty acids (myristic and oleic acids etc.) and procyanidins from betel nuts (the seed of Areca catechu L.) were respectively revealed to be the major antibacterial principles against a primary cariogenic bacterium, Streptococcus mutans, and the major inhibitory principles against glucosyltransferase from S. mutans.     

临床输液反应的分析与预防

目的对临床发生的输液反应进行分析,找出发生的原因,探讨预防措施。方法:对30例输液反应资料进行分析。结果:以热原反应最为多见,占76.67%,而过敏反应,占16.67%,局部反应,占6.67%。结论:严格执行消毒制度,遵守无菌操作规程,把好药品和输液器具质量关,合理用药,注意配伍等是减少临床输液反应的关键。
