本文在福建省直机关老干部630例体验资料的基础上进行了脑动脉硬化症(CAS)计量诊断研究。采用多元逐步判别分析模型,在本底资料的基础上,建立CAS计量诊断判别函数式,选入的指标依次是甘油三酯、血小板1分钟聚集率、全血粘度(高切)、纤维蛋白质、人像特点回忆、家族高血压、卧住收缩压和眼底动脉硬化等级。继而运用临床科研设计、衡量与评价(DME)方法,考核该函数式的诊断效能。将630例本底资料逐个回代方程,其灵敏度、特异度、误诊率和漏诊率分别为93．3％、92．04％、7．96和6．67％,其他11项反映诊断能力和综合应用价值的指标亦令人满意,认为CAS计量诊断判别函数式具有良好的诊断效能,有一定的推广应用价值。
This article is based on the experience of 630 cadres in Fujian Province organs of cadres on the basis of diagnostic tests of cerebral arteriosclerosis (CAS). Using multiple stepwise discriminant analysis model, based on the background data, the diagnostic function of CAS was established. The selected indicators were triglyceride, platelet aggregation rate at 1 minute, whole blood viscosity (high shear), fibrin, Portrait Features Memories, Family Hypertension, Systolic Blood Pressure and Arterial Arteriosclerosis Rating. Then use the clinical research design, measurement and evaluation (DME) method to assess the diagnostic efficacy of the function. The sensitivity, specificity, misdiagnosis rate and misdiagnosis rate of 630 cases were 93.3%, 92.04%, 7.96% and 6.67%, respectively. The other 11 items, which reflect the diagnostic ability and Comprehensive application of the value of the index is also satisfactory, that the CAS diagnostic diagnostic function has good diagnostic efficacy, there is a certain value of the promotion.
