急性缺血中风阴阳类证证候分级阈值初探

Exploration on Patterns of Acute Ischemic Stroke and the Threshold of the Symptom Fractionation

目的探讨急性缺血中风病临床证候分布规律,初步制定证候分级诊断量化标准。方法采用文献调研、自制临床证候信息采集表、运用描述性分析、聚类分析、判别分析、逐步Logistic回归分析、频数归一化权重及参考值范围制定方法。结果1252例急性缺血中风病病人临床主要证候及证候诊断阈值分别为:火热证占43.7%,诊断阈值≥3分;阴虚证占19.1%,诊断阈值≥3分;气虚证占33.7%,诊断阈值≥0分。结论初步制定急性缺血中风病证候四诊指标权重、证候诊断阈值以及辨证分型分级标准,可供临床诊断与疗效评价之参考。

Objective To study the clinical symptom and diagnostic features of the acute ischemic stroke and preliminary quantization diagnosis standard for the symptom. Methods Based on data of 1 252 patients （pts） with acute ischemic stroke, all data were analyzed by description analysis, cluster analysis, discriminatory analysis, step by step Logstic regression analysis, frequency normalization weight analysis and reface value scope method. Results The main symptoms and diagnosis threshold of 1252 pts were： fire- heat （43,7%）, the diagnosis threshold value ≥ 3. Yin asthenis （19.1%）, the diagnosis threshold value ≥ 3; Qi deficiency （33.7%）, the diagnosis threshold value ≥ 0. Conclusion For pts with acute ischemic stroke, the diagnosis threshold of the symptoms, differentiation of symptoms, signs for classification and grade of syndrome could be provided for clinical diagnosis evaluation and curative effect.
