中风病不同阶段四诊信息的指标聚类分析

为探讨中风病中医证候发生和演变规律，对195例中风病急性期病人，进行了90天内的调查和随访，对以发病3天、第28天、第90天为代表的三个阶段的中医四诊信息进行指标聚类。依据中医理论及临床，对中风病不同阶段的证候表现进行比较分析。聚类结果提示将中风病患者发病前3天四诊信息分为气虚血瘀、痰热、气阴两虚三类；发病第28天的四诊信息分为气虚、痰湿、血瘀、痰热四类；中风病第90天的信息分为气虚血瘀、气虚、痰热、痰湿四类较为合理。可见中风病不同时点的证候表现有所不同，且在治疗康复过程中体现出由错综复杂到相对单纯的变化过程。

Cluster Analysis of TCM Diagnostic Data in Different Stages of Ischemic Stroke

To discuss the distribution and evolvement of TCM syndromes in ischemic stoke, we investigated the TCM diagnostic data from 195 eases in the first three months. After the cluster analysis based on the data of the first 3 days, 28 days, 90 days after the attack, information of the first three days indicated that the variables could cluster into qi deficiency and blood stagnation, phlegm-heat, qi and yin deficiency three groups; the information of the 28 days indicated that the variables could duster into qi deficiency, phlegm-wet, blood stagnation, phlegm-heat four groups; the information of the 90 days indicated that the variables could cluster into qi deficiency and blood stagnation, qi deficiency, phlegm-heat and phlegm-wet four groups. The cluster analysis result shows us a dynamic process of the syndrome evolvement, TCM syndromes axe variance in different stage, and become simplicity from complex after treatments.
