中文摘要：

目的：利用中医药治疗糖尿病现代临床研究文献探讨糖尿病中医四诊信息的规律性。方法：收集整理中医药治疗糖尿病现代临床研究文献。采用频数分析与聚类分析的方法，分析文献中四诊信息的规律性。结果：从现代医学角度分析，糖尿病四诊信息可以分为四类：疾病诊断相关症状或体征、疾病诊断相关症状或体征的中医特征性描述、疾病诊断不太相关的全身症状或体征、疾病诊断无关的舌脉象。症状出现频率高的是疾病诊断相关症状。运用聚类分析将这28项症状和舌脉象聚类为3类，能分别代表中医脾肾气虚、肺胃热盛，心脾两虚、胃热炽盛和肾阴亏虚、胃热炽盛证候类型。若将这28项症状和舌脉象聚为10类，则分别代表中医治疗糖尿病辨证过程中证候分类的常见症状或舌脉象的组合。结论：从统计学角度出发，糖尿病现代文献中的中医四诊信息具有规律性，同时该规律性与中医学辨证理论一致。

英文摘要：

objective：To probe the regularity of the information from the TCM four diagnostic methods by analyzing the modern clinical research literature about the treatment of the diabetes by TCM. methods： collecting and arranging the modern clinical research literature, then using the statistical methods of frequency analysis and cluster analysis to investigate the regularity of the information from the TCM four diagnostic methods, result： based on the theory of the modern medicine, four kinds of information from the TCM four diagnostic methods about diabetes are categorized：the symptom or sign related with diagnosis of the disease,the distinctive description in TCM of the symptom or sign correlated with diagnosis of the disease,the general symptom or sign scarcely related with diagnosis of the disease ,tongue image and pulse tracing unrelated with diagnosis of the disease, the symptoms with high frequency are the symptom related with diagnosis of the disease, twenty- eight symptoms and tongue - pulse manifestation are analyzed ,and three categories are clustering by using the method of the cluster analysis,they can represent the syndrome types respectively：qi deficiency of spleen and kidney,excessive heat of lung and stomach,deficiency of both heart and spleen,flaring up of stomach heat and yin deficiency of kidney,flaring up of stomach. If clustering these twenty - eight symptoms and tongue - pulse manifestation into ten categories, they will represent the combination of common symptoms or tongue- pulse manifestation in TCM syndromes about diabetes, conclusion-based on the theory of statistics, the information from TCM four diagnostic methods in the modern literature about diabetes has its own regularity ,which is accord with the theory of the TCM syndrome differentiation.
