阳江高本底地区居民健康流行病学调查数据库与统计分析方法

目的 研究应用计算机数据库技术及先进统计分析方法,对阳江高本底地区10多万人20余年的健康随访研究资料和剂量学调查资料进行储存、管理和分析。方法 通过调研和比较分析,确定采用Foxbase系列数据库管理系统按专题建立数据库,借助于ID号实现记录连接；一般统计分析由SAS完成；交叉分组人年列表由Epicure中的Datab完成；癌症相对危险分析用AMFIT程序。结果 建立了40MB的各专题研究库,主要包括：10余万人的人口学数据库(1979～1995)、1.2万人的死因数据库(1979～1995)和526个村庄6783户、5273人的剂量数据库。提出了动态群组研究资料(1979～1986)与固定群组研究资料(1987～1995)的合并方法：首选方法是建立假想的基于记录连接的以1979年为起点的(固定)群组。另一方法是将不同阶段群组研究的人年表分层直接相加。计算了每个成员基于卧室内、起居室内、室外村平均剂量率与性别-年龄别居留因子的累积剂量。完成了以性别、atainedage、随访年代及剂量交叉分组的人年列表,对癌症死亡资料(1979～1990)进行了危险分析。结论 应用计算机数据库管理系统与统计分析技术使阳江高本底地区研     

胸椎黄韧带骨化症手术并发硬脊膜损伤或脑脊液漏的原因分析及防治

目的：分析胸椎黄韧带骨化症(ossification of ligamentum flavum,OLF)手术并发硬脊膜损伤或脑脊液漏的原因，并探讨其防治方法。方法：对103例手术治疗的胸椎OLF患者中并发硬脊膜损伤或脑脊液漏病例的临床资料进行回顾性分析。结果：30例发生硬脊膜损伤，发生率为29．13％；22例术后发生脑脊液漏，发生率为21．36％，其中21例患者经以俯卧位为主的综合治疗后痊愈，1例发生伤口全层裂开，二次手术后痊愈。结论：硬脊膜损伤或脑脊液漏是胸椎OLF手术易发生的并发症；俯卧位为主的综合治疗是治疗术后脑脊液漏的有效方案，但患者较痛苦，有待改进。     

Effect of environment on extremely severe road traffic crashes：retrospective epidemic analysis during 2000-2001

Objective: To make an epidemiological analysis of the effect of environment on extremely severe road traffic crashes (RTCs). Methods: Epidemiologic data of extremely severe RTCs associated with environmental factors, including weather, topography, road conditions and other traffic conditions in Mainland China during 2000-2001, were collected and analyzed. Results: ( 1 ) During 2000-2001, there were 3 365 extremely severe RTCs with 13 666 deaths, 12 204 injuries and a direct economical loss of 136 million RMB. ( 2 ) Most extremely severe RTCs occurred in fine weather days and in the daytime. The high occurrence sites were plain areas, horizontal and straight roads, Grade B and C roads, ordinary road segment, and asphalt, smooth and mixed roads. (3) Compared with other RTCs, extremely severe RTCs were more likely to happen under following conditions: on cloudy, snowing, misty and blustering days; in hill and mountainous areas; on crooked and sloping roads; on freeway, Grade A, B, and C roads; mixed roads; ordinary, bridge, narrow and transitional roads; sand and dirt-roads; without traffic control measures; night without lighting. (4) Extremely severe RTCs of mountainous area or crooked and sloping roads were most severe in terms of deaths and injures per crash. Conclusions: Extremely severe RTCs are closely related with environmental factors. Rational road programming, enhancing road establishment and improving road conditions are probably effective measures to reduce the road traffic injuries.     

从中日沿海城市部分老年人生活满足感比较看老年社区护理的发展

目的 通过比较中日两围老年人生活满足感，探讨老年人社区护理的发展方向。方法 中国大连市选取60岁以上老年人，进行人户调查，日本滨松市选取俱乐部的65岁以上老年人，填写问卷。结果 除在与亲人、朋友交往及存钱以防万一等方面外，2国老年人在其他生活满足感方面比较，差异均有统计学意义，P〈0．05。结论 中日两国不同的经济基础导致了不同层次需求的差异。在中国发展老年人社区护理，一方面可以借鉴国外经验，从物质基础上改进和完善；另一方面，借助传统文化优势，从社会风气上进行促进。     

1993年云南省瑞丽等地吸毒者艾滋病病毒感染定群研究

１９９３年３月对已建立一年的吸毒者定群研究现场──云南省德宏州瑞丽市、陇川县及潞西县再次进行调查。本次调查７５５例吸毒者及１０２例配偶。从１９９２年进入定群研究ＨＩＶ阴性的８９例静脉吸毒者中，１９９３年又采到血样有５４例，其中９例血清转阳。瑞丽市、陇川县及潞西县１９９２年和１９９３年静注者血清阳转率（／百观察人年）分别为４３．２％及４０．０％，１２．２％及１２．２％，０％及０％。１９９３年新进入定群研究的１１６例静注者中，采集到血样的有１０４例，发现ＨＩＶ阳性３８例。上述三市县１９９２年及１９９３年入定群研究的静注者的ＨＩＶ感染率分别为８１．８％及８５．７％，４４．６％及４０．０％，５．１％及０％。可以看出血清阳转率的高低与ＨＩＶ感染率高低相吻合。ＨＩＶ阳性者的配偶１９９０、１９９２及１９９３年的ＨＩＶ感染率分别为３．１％、９．８％和７．４％，有上升趋势。潞西县ＨＩＶ阳性者少，静脉注射出现时间晚，但近年来静脉吸毒者比例上升快，值得注意。     

Intakes and major dietary sources of cholesterol and phytosterols in the British diet

Cholesterol intakes in Britain have been re-estimated by analysing Total Diet samples taken in 1991 and from 1993 National Food Survey records. The Total Diet samples contained only 284 mg/day compared with 319 mg/day in 1987 and 337 mg/day in 1981, while the National Food Survey showed intakes had fallen to 238 mg/day from 259 mg/day in 1990 and 405 mg/day in 1970-75. More details of the intakes by adults in 1986/87 are given, and compared with the results from the other methods. Daily intakes of eight phytosterols were also estimated, the main ones being β-sitosterol, campesterol, stigmasterol and 57-stigmastenol whose intakes were 104, 49, 10 and 4 mg/day, respectively, in 1991. These intakes had increased since 1981, reflecting the rising consumption of vegetable oils.     

Mortality study of asbestos cement workers

The present study describes cause-specific mortality of asbestos cement workers in the Emilia Romagna region of Italy. The cohort included workers in ten factories, most of which started operating between 1955 and 1965. Asbestos, mainly chrysotile, constituted 10%–20% of the dry component of the mixture. Crocidolite range between 5% and 50% of total asbestos. Asbestos concentrations up to 44 ff/cc were reported prior to 1975, while in recent years they have usually been below 0–1 ff/cc. The cohort included 3341 workers who had at some time been employed in the ten factories under study. Their mortality experience was compared with that of the population resident in Emilia Romagna. Vital status was ascertained at 1989. Seventy-three subjects were lost to followup (2.2%). Mortality from all causes and from all types of cancer was increased in the cohort. Malignant neoplasms of the respiratory tract showed a significant increase (SMR: 134; 90% confidence interval: 101–175; 40 observed) due to lung cancer (SMR: 124; 90% confidence interval: 91–166; 33 observed) and neoplasms of the pleura, mediastinum, and other parts of the respiratory tract (SMR: 602; 90% confidence interval 237–1267; 5 observed). The discrepancy between observed and expected mortality mainly concerned subjects with at least 20 years of employment in the factories. Five more cases of histologically confirmed mesothelioma occurred after the end of follow-up.     

公共服务体系与中韩公共管理改革

公共服务体系是现代文明社会的基本标志，也是现代社会稳定发展的基础，公共经济学和欧美国家的发展经验已经证明了这一点。韩国是从上世纪80年代取得“汉江奇迹”后，在经济增长成就和产生的社会问题的双重推动下，开始了以奉侍型政府、国民中心等为目标的管理改革，并逐步建立起比较完善的公共服务体系。中国在进入新世纪后提出建设服务型政府，开始建立和完善公共服务体系。研究表明，在建立公共服务型政府的改革中，两国在价值理念、改革目标、改革路径和举措等方面都有许多相同相似的方面，但也存在差异性。总体上，韩国在建立公共服务型政府，提高公共服务质量等方面要比中国先行一步，有许多值得中国政府学习和借鉴的地方。     

The Alcohol Beverage Warning Label: When Did Knowledge Increase?

This article presents data on the awareness of the alcohol beverage warning label among a sample of 5,169 inner city African-American gravidas seeking prenatal care. While the label law was implemented in November 1989, a significant increase in knowledge of the label did not occur until March 1990. Women who predominantly consumed wine coolers and beer, and those under age 30 were more likely to know about the label than their counterparts.
