Intelligent dialogue based on statistical models of clinical decision-making

The independence Bayesian model has been used widely in computer programs designed to support clinical decision-making. A reasoning strategy has been developed to enable these programs to conduct clinically pertinent dialogue and explain their reasoning. It has been implemented in a program for the diagnosis of acute abdominal pain based on the Bayesian model of de Dombal et al. Several features of the dialogue design have been adopted from artificial intelligence research, including shared initiative and critiquing. The program adopts a flexible goal-driven strategy, attempting to confirm the clinician's diagnosis or rule out the likeliest alternative. Symptoms and signs are selected in order of their expected weights of evidence in favour of the hypothesized disease.

Matching blood donations to type-specific product needs: A recruitment technique

The conversion of multiple whole blood donors to apheresis donors is a challenge since a rapidly expanding apheresis donor base could erode homologous collections. We addressed this concern with a plan to enhance apheresis recruitment as well as donations among homologous donors with types O and B blood. Focusing the donor's attention on blood type as it relates to type-specific product needs was the basis of our approach. A matrix was used to recruit the desired types for the desired procedures (whole blood, platelet/plasma apheresis). The matrix instructed donors of blood types O, A-, and B- to primarily give whole blood and to give apheresis as a secondary donation. Donors AB, A+, and B+ were primarily directed to apheresis donations, whole blood donation being secondary. A+ and O- donors only gave their secondary donation if they were at maximum donations with the primary donation. The collections by blood type in percentages for 12 months of 1992/93 for whole blood were O+ 38.9, 0- 7.3, A+ 29.5, A- 5.7, B+ 11.9, B- 2.1, AB+ 3.7, AB+ 0.7. For apheresis it was 0+ 36.2, 0- 6.7, A+ 33.0, A- 6.6, B+ 10.4, B- 1.2, AB+ 4.9, AB+ 1.0. In 1992/93, A+ and B+ apheresis collections as compared to total apheresis collections increased by 4.9% and 13.7%, respectively. For O group apheresis donations, a decrease of 2.5% was shown and A+ whole blood donations decreased by 5.35%. During the same period of time, total apheresis collections increased by 3,058 units. We demonstrated that integration of apheresis recruitment with type-specific whole blood recruitment yielded significant increases of type-specific products.     

激素敏感型肾病单个核细胞培养上清液对大鼠肾小球多阴离子及超微结构的影响

用刀豆蛋白Ａ刺激激素敏感型肾病单个核细胞，并将其培养上清液灌注于大鼠肾内。结合电镜观察，用图像分析仪及体视学方法分别对其肾组织胶体铁染色切片和电镜照片上的足突和滤过裂隙的平均宽度进行测定。结果表明：该病极期上清液灌注的鼠肾小球多阴离子明显减少，足突肿胀、融合，滤过裂隙变窄；而该病缓解组和正常对照组则为阴性。说明该病单个核细胞培养上清液可引起鼠肾小球微小病变型肾病综合征的病变，并揭示该变化可能是由其上清液中一种异常的Ｔ淋巴细胞因子所致。     

宝鸡市城市饮用水与人群健康效应的调查研究

本文通过对宝鸡市居民饮自来水和自备井水的人群进行了回顾性和前瞻性调查分析，结果发现，饮自来水与饮未经处理自备井水明显的差异。即调查组（饮自来水）肠道传染病发病率为４．２２％和６．８２％，对照组（饮自备井水）发病率为７．７１％和１１．５６％经卡方检验Ｐ＜０．０５，差异有显著性。从发病病种来看，调查组和对照组均以腹泻为主，其次为痢疾和肝炎，发病率分别是：腹泻，调查组为３５．５９‰和６３．００‰，对照组     

Morphological and biochemical correlates of chemical induced injury in the lung

We have reviewed some of the factors which contribute to lung damage by various toxicants. These include disposition of the chemical, its metabolism, individual cell type susceptibility and the potential for the tissue to repair. We have discussed the use of biochemical parameters to measure the functional activity of individual cell types in order to predict the damage to specific cell types and concluded that careful morphological analysis of lung tissue is likely to provide a more sensitive and informative measure of specific cell type injury. However, in order to investigate the mechanism of toxicity of pulmonary toxicants it is essential to establish the primary biochemical event that leads to cell damage and morphological change. The importance of separating the relevant biochemical change(s) from the cascade of biochemical events associated with dead and dying cells and the reparative response of the lung is emphasised.This report results from a discussion sponsored and organised by the Advisory Subgroup in Toxicology (AST) of the European Science Foundation's Standing Committee for the European Medical Research Councils and held at the Medical Research Council Toxicology Unit, Carshalton, U.

早孕妇女人工流产方式意向的临床调查研究

人工流产(简称人流)是各种避孕失败的主要补救措施,目前早孕妇女人流的主要方式有吸刮术与药物流产两种。本文通过对天津市黄河医院意外早孕妇女选择人流方式意向的临床调查研究,探讨现阶段该两种人流方式的可接受性,结果:1000例早孕妇女中选择药物流产(简称药流)者666例(66.6％),吸刮术者334例(33.4％)。本组选择人流方式的理由,其中519例(51.9％)认为药流痛苦少,占第一位,认为手术干脆而选择吸刮术的217例(21.7％),占第二位,其它依次为吸刮术费用低、药流不必手术、吸刮术流产完全、药流不需请假、吸刮术出血时间短、药流安全、吸刮术副作用少、药流保密。药流是近年来使用的流产新方法,本组研究资料及意向选择只反映现阶段早孕妇女的接受状况。
