脾虚证计算机量化诊断的探索

Evaluation and Analysis of Diagnostic Messages About the Spleen-deficiency Syndrome

探索以计算机数据库管理系统Ｆｏｘｐｒｏ２．５ｆｏｒＤｏｓ为平台，运用信息评价分析的方法对脾虚证相关的２２个证候进行评价分析，筛选出有较大诊断价值的１１个证候，其中５个证候的诊断贡献率最大，依次为食欲减退（２２．７９％）、食后腹胀喜按（１８．３３％）、面色萎黄（１７．９９％）、肌瘦无力（１７．０４％）、大便溏泄（１２．１９％），总和达８８．３４％。认为脾虚证诊断的定量化应以证候的信息量即诊断贡献率的大小作为基础。

Eleven valuable symptoms and signs were sieved from them. The following five can provide the largest diagnostic contribution rate: anorexia (22.79%),epigastric distension after meal which is relievable by pressing (18.33%), sallow complexion(17.99%),emaciation and weariness(17.04%) and loose stool(12.19%),summing up to 88.34%.We hold that the quantification of spleen_deficieny syndrome diagnosis should be based on the message quantity of symptoms and signs, i.e. the diagnostic contribution rate.
