现阶段县级卫校在初级卫生保健中的作用探析

依据乡村医生人力结构现状调查结果,就现阶段县级卫校在初级卫生保健中的作用及今后面向乡村医生办学的可行性作了具体的分析和探讨。结论是:提高质量,加强对在岗乡医进行系统化正规中专层次的职后复训,应是县级卫校今后1O年的最主要的任务。     

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.     

A combined course of primary health care practice and family medicine at the University of Gezira

The community-based course presented is a longitudinal course running through four semesters in the Faculty of Medicine, University of Gezira, Sudan. Students combine their regular work in primary health care centres with attachments to a number of families in Wad Medani town. They continue to visit these families regularly throughout their entire medical course with the aim of studying them and helping them with some of their medical and psychosocial problems.     

P53、P16、Bcl-2基因及产物在原发性肺癌中的表达及其临床病理意义

目的 :探讨原发性肺癌 Mtp5 3、p16、Bcl- 2的异常表达与肺癌发生、发展的关系 ,以及它们之间的调控关系。 方法 :用免疫组化技术检测 (L SAB) 114例原发性肺癌组织中 p5 3、p16、Bcl- 2的表达。并用 PCR技术对 6 2例 p16蛋白丢失的肺癌组织中 p16外显子 2 (p16 E2 )的缺失进行分析。 结果:p5 3蛋白异常表达与肺癌组织学类型、分化程度无关 (P >0 .0 5 ) ,但与淋巴结转移情况有关 (P >0 .0 5 )。 p16蛋白阳性表达率与肺癌的组织学类型无关 ,但是其表达水平与非小细胞肺癌 (NSCL C)的细胞分化程度和淋巴结转移密切相关 (P <0 .0 5 )。 NSCL C中 p16E2的缺失率为 45 .2 %,其缺失水平随淋巴结转移和组织学分级的升高而升高 (P <0 .0 5 )。 SCL C(小细胞肺癌 )和正常肺组织中无 p16 E2的缺失。 Bcl- 2在小细胞肺癌中阳性率 6 2 .2 %显著高于 Sq Ca(鳞癌 )的 2 5 %和 Ad Ca(腺癌 )的 9.1%(P <0 .0 5 ) ,与细胞分化程度和淋巴结转移情况无关。另外 ,p5 3与 p16蛋白之间存在调控关系。 结论 :(1) p16、p5 3、Bcl- 2的异常参与肺癌的发生、发展过程。 (2 ) p16基因及产物的异常表达与 NSCL C的组织学分级和淋巴结转移相关 ,可能参与 NSCL C的发生、发展和转移过程。 (3) Bcl- 2反映 SCL C的分之生物学行为和临床     

肝动脉变异及其在肝癌介入治疗中的意义

本文收集１９９２年１月至１９９５年５月在我科作肝动脉化疗栓塞术和肝动脉化疗灌注术的中晚期肝癌１６０例，将每例病人的肝动脉造影所见与临床资料及随访结果一起进行分析。     

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。     

Kindergarten and first grade: A time for developing and nurturing gifted behaviors in young children

This article concludes that there is a tremendous need for gifted programs at the kindergarten and first grade levels. A review of the literature suggests that it is difficult to identify young gifted children through traditional screening techniques. The author concludes that Renzulli's Enrichment Triad Model may prove useful for identifying young gifted children.
