More than wisdom

This paper presents and interprets empirical findings from field studies in a Bambara village in the Republic of Mali in order to place the traditional position of the elderly in cultural context. The significance of a seniority principle underlying the social structure of African society is emphasized. Thus attitude and behavioral changes which affect the status of the elderly have wider ramifications for the society as a whole. Attention centers on the role of age sets, myth and ritual, ancestor worship and socialization practices as elements of a total cultural system in which the rules of seniority provide an organizing force. In the last section, the ways in which social change threatens the viability of a social system governed by the seniority principle are reviewed. Signs of breaks in the solidarity of the traditional community are noted. Finally, two strategies for improving the position of the elderly in the African countryside as the traditional system disintegrates are proposed.To the people of Sonongo in gratitude.

呋苄青霉素药代动力学及组织分布的研究

呋苄青霉素是由我国开发成功的一个酰脲类青霉素。本项研究采用微生物法,以狗和正常人为受试对象,以氧哌嗪青霉素和羧苄青霉素为对照进行药代动力学研究,结果表明,3个药的药—时曲线符合二室开放式模型,呋苄青霉素较其它对照药具较高的即刻血浓度和较低的肾清除率。用微生物法和放射自显影法测定的呋苄青霉素在小鼠体内组织分布汪明,呋苄青霉素广泛分布于体内各组织,尤其在肺、肝、肠中的浓度明显高于羧苄青霉素。     

脑动静脉畸形的供应动脉及导出静脉与出血危险性的关系

本文通过分析５０例脑动静脉畸形（ＡＶＭ）的全脑数字减影血管造影（ＤＳＡ）资料及手术探查结果，探讨ＡＶＭ的深、浅及供血、引流血管数量与出血发生率的关系。经统计比较发现：深部较浅部ＡＶＭ出血率高；供应动脉条数多于导出静脉条数者及仅有单条导出静脉出血率最高，并与其他组有显著性差异（Ｐ＜０．０５、Ｐ＜０．０１）。因此，我们认为：在临床工作中对这些ＡＶＭ患者应给予足够的重视。     

Psychiatric morbidity among people aged 85+ in 1987. A follow-up study at two and a half years: Associations with changes in psychiatric morbidity

This article reports findings from a longitudinal survey of very elderly people living at home in London. The research aimed to identify social, psychological and physical characteristics associated with positive ageing and successful survival in the community in later life and its converse—negative ageing—as well as the associated policy implications. Associations with psychiatric morbidity, measured using the General Health Questionnaire, among sample members without cognitive impairment between the baseline interviews in 1987 and at follow-up, two and a half years later in 1990, are reported. Twenty-five per cent of survivors scored over the threshold of the GHQ in 1987 and 30% scored over the threshold in 1990. Half of those with a score over the threshold in 1990 also scored over the threshold in 1987. Hierarchical regression (using residualized change analysis) was used to estimate the effects of the independent variables on changes in psychiatric morbidity. The most significant predictor of psychiatric morbidity (GHQ score) in 1990 was baseline GHQ score, followed by health and functional status scores. Health and functional status were also the strongest predictors of baseline (1987) GHQ scores. The uniqueness of the study lies in the collection of follow-up data on a sample of very elderly people, given that most surveys are corss-sectional and contain too few people aged 85+ to merit separate analysis. It contributes to the small body of literature on outcome of depression. The lack of consistent associations with recovery from psychiatric morbidity in the literature enhances the importance of studies aiming to identify factors associated with different outcomes.     

Intraoperative radiotherapy in the multidisciplinary treatment of bone sarcomas in children and adolescents

From September 1984 to December 1989, 38 patients of pediatric age with localized bone sarcomas received intraoperative radiotherapy (IORT) as part of a multidisci plinary treatment program. The age ranged from 6 to 21 years. The tumor histologies were 22 osteosarcomas and 16 Ewing's sarcomas. Thirty-four had initial primary disease (90%) and 4 were treated for local recurrence (10%). IORT was used on 32 untreated patients and in 6 previously treated with external beam radiotherapy (EBR). The IORT field included the surgically exposed tumor bed area. Single radiation doses ranging from 10 to 20 Gy were delivered, using 6–20 MeV electron beams. The median follow-up time for the entire group is 25 months (2–65+ months). The projected 5-year disease-free and overall survival rates are 65% and 69%, respectively. One patient developed a local recurrence in each histological group: one chondroblastic osteosarcoma and one cervical Ewing's sarcoma. Six patients died from metastatic progression: 3 initially recurrent tumors and three primary disease cases. Severe neuropathy and soft tissue necrosis were seen in some patients as IORT related complications. IORT is a feasible technique to be integrated in multidisciplinary programs that may promote local control in pediatric and adolescent patients with bone sarcomas. Peripheral nerves are dose-limiting tissue structures for IORT.     

医院统计在医院要素分配中的作用

目的 为支持医院内部要素分配调整改革，医院统计应展开与要素分配有关的项目进行统计，为医院要素分配向高、精、尖、绩效好的医务人员倾斜提供统计数据。方法 应用ExCEL软件的合并功能对病人信息和病案信息进行深层次的挖掘、提取、重新整合统计，制成简明易懂的统计报表给予反馈公布，作为医师提取个人奖酬、职称晋升或聘任竞岗的考核依据。结果通过统计作用实现了劳动价值创造，调动了广大医务人员的积极性，促使医院经营理念成为引导个人自觉行为的杠杆，实现了医院提高综合竞争实力的整体效应。结论 要素分配中统计工作应遵循公平、合理、反映医院经营理念的原则和利用网络科技实现高效管理并且应与改革同步，深化统计内涵，完善医院的统计方法。
