人型支原体感染的血清流行病学研究

1989年3～4月对南京铁咯分局1423名健康人进行了人型支原体感染的血清流行病学调查。结果表明,人群中存在Mh感染抗体阳性率为3.72％,GMT为1:3.38。感染与性别、年龄、职业、婚姻、病史以及性接触等因素有关。提示该病是一种性传播疾病,应引起高度重视。

Recommendations for the Conduct of Acute Inhalation Limit Tests

This paper reviews the scientific issues related to exposureconcentrations and particle sizes used in acute inhalation limittests. The current United States Environmental Protection Agency(USEPA) recommended exposure concentration for such tests is5 mg/liter, while this level is very high, it is often achievable.On the other hand, its toxicological relevance is questionable.The USEPA recommendation that 25% of the particle distributionbe less than 1 µm is a more difficult issue to address.Physical laws for aerosol particle generation and behavior limitthe minimum size of particles in an exposure atmosphere at aconcentration of 5 mg/liter. Particle size also influences depositionsite in the respiratory tract. Since damage to any region ofthe respiratory tract can produce lethality, and it is not possibleto predict, a priori, the most responsive region of the tractor the most harmful particle size of an untested agent, acutelimit testing should employ particles in a size range that depositsthroughout the entire rodent respiratory tract. Particles between1 and 4 µm mass median aerodynamic diameter (MMAD) arewell suited for such studies. It is, therefore, recommendedthat the limit test concentration should be the highest concentration(up to 5 mg/liter) that can be achieved while still maintaininga particle size distribution having an MMAD between 1 and 4µm.     

对医院药事管理委员会系统工程管理的初探

The telephone survey: a methodological strategy for obtaining information

Studies have shown that students and the general population have little knowledge about nursing schools and the nursing profession. This study investigates the extent to which a sample of the population of Brazil is aware of the existence of nursing schools, and how they have obtained this information. Data were collected by telephone interviews. The sample consisted of 326 subjects whose telephone numbers were taken from the telephone book. Analysis showed that 73% of the subjects were aware of the existence of two nursing schools in the city; however, 65.03% did not know the names of these schools. Direct communication with friends and family, as well as indirect communication by television and advertising, were the sources of information mentioned by those questioned.     

加强保健措施 降低孕产妇死亡率的试点研究

经调查河南省七县1988～04～1989～03孕产妇死亡率为136.1/10万,高于全国平均水平(94.7/10万)。从七县中选择了死亡率偏高的三个县(147.9/10万)为样本.进行厂降低农村孕产妇死亡率保健措施的研究。自1990年4月1日～1992年3月31日。在三县采取了以下保健措施:①加强基层妇幼卫生建设,特别是中心乡卫生院的建设,②整顿和完善三级保健网;③建全孕产妇系统管理制度,高危妊娠筛查,转化和转诊制度,④配备必要设备,建立联合小产院,实行定点接生。两年内孕产妇死亡率,由1989年的147.9/10万下降到67.7/10万,下降幅度为54.44%,最高达72.1%。此工作为实现2000年孕产妇死亡率下降一半的规划目标提供了依据。     

自体颅骨碎片及屑修补颅骨缺损(附60例报告)

应用自体颅骨碎片及骨屑对60例在造成颅骨缺损术同时行颅骨缺损修补术。缺损面积直径最小者2cm,最大者10cm。术后随访1个月至5年,病人颅骨缺损修补处外观正常,无凹陷,触之硬,与正常颅骨处类似。6个月拍X线片示颅骨修补处类似正常颅骨形态。     

中性粒细胞的化学发光测定

用化学发光法检测粒细胞吞噬功能具有灵敏、准确、快速等优点。用我校同位素实验室LS3801型液体闪烁分析仪,全部使用国产试剂,建立了分离的中性粒细胞化学发光测定法,并对影响因素作了初步观察和探讨。实验表明,此法既可用于中性粒细胞吞噬杀菌功能机理研究,亦可用于临床监测。对糖尿病人粒细胞功能化学发光测定结果,显示了此法应用的潜力。     

Natural history of atopic dermatitis and its relationship to serum total immunoglobulin E in a population-based birth cohort study

We investigated the natural history of atopic dermatitis (AD) in a population-based birth cohort and assessed whether children at risk of visible eczema at 5 years of age can be identified from total immunoglobulin E (IgE) levels measured at 8, 12 and 18 months. AD data collected included a whole body examination for visible eczema at 49 months (4 years) and 61 months (5 years) of age and parent completed questionnaire data throughout their early lives. Children were divided into four groups based on their natural history of early AD: persistent (AD at 1, 6, 18, 30 and 42 months, n  = 34), intermittent early onset (before 18  months of age, n  = 495), intermittent late onset (18–42 months of age, n  = 273) and unaffected ( n  = 429). Visible eczema at 5 years of age was present in 12.2% (117/957) (95% confidence interval [CI] 10.1–14.3%) of the children. Levels of total IgE at 8, 12 and 18 months of age were associated with early onset of AD, but not with AD of later onset. For all four natural history groups, the geometric mean total IgE at 12 months was higher in those who subsequently had visible eczema than those who did not. However, the degree of overlap was such that total IgE at 12 months of age was a poor predictor of eczema at age five. A cutoff point of 78 kU/l had the highest positive predictive value for visible eczema at 5 years of age of 28.6%, with a sensitivity of 12% and specificity of 95%.
