目的：基于无尺度网络分析方法研究肠癌中医药治疗特点。方法：通过肠癌结构化临床信息采集系统，采集2008~2011年广安门医院肿瘤科的肠癌住院患者145 例，运用无尺度网络方法，从中药的功效、种类、配伍关系等方面，探讨肠癌中医治疗特点。结果：治疗肠癌多采用扶正为主的方剂，以四君子汤使用最多，组方时以补气药为主，清热药、利水渗湿药、理气药、活血化瘀药、消食药和化痰药居多。中医治法及辨证用药随治疗阶段和病程阶段而有所变化。结论：通过无尺度网络分析方法可以相对定量、直观地展示肠癌中医治疗规律。

This article was aimed to study the characteristics of intestinal cancer by traditional Chinese medicine (TCM) based on the scale-free network analysis method. History information of 145 hospitalized cases from 2008 to 2011 was collected from the Oncology Department, Guang Anmen Hospital, in the clinical collection system. The rule of medication in the treatment of intestinal cancer by TCM was explored by scale-free network analysis method from several aspects, such as effects, classification and compatibility relations. The analysis results of 145 intestinal cancer cases showed that strengthening the body resistance was the main treatment principle. Si-Jun-Zi (SJZ) decoction was used with the highest frequency. In the prescription design, qi -supplementing herbs were the most. The heat-clearing, dampness-eliminating, qi-regulating, blood-activating and stasis-removing, food stagnation removing and phlegm-removing herbs were also used frequently. The TCM treatment and syndrome differentiation will be changed due to the treatment and disease stages. It was concluded that scale-free network analysis method is able to relatively show the TCM treatment rule of intestinal cancer quantificationally and intuitively.
