OBJECTIVEThe efficiency network is a complicated network for revealing the efficient mechanism of traditional Chinese medicines (TCMs) and relations among efficiencies. The efficiency-property relations were used to establish a warm-pungent-liver efficiency network to explain the principle of treating hepatoma with medicines invigorating blood circulation and eliminating blood stasis. Safflower, a warm-pungent medicine distributing along the live meridian, was taken for example to discuss the efficiency network' s application in the identification of active ingredients of TCMs and the combination.
METHODIn the early stage of this study, combined warm-pungent-liver medicines distributed along the liver meridian and invigorating blood circulation and eliminating blood stasis were taken as the study objects to collect the pharmacological effect data of warm-pungent-liver medicines and obtain the pharmacological effect combinations with the highest blood circulation-invigorating association by the association rules and the chi-square test. The pharmacological target data recorded in the DrugBank database is used to establish the warm-pungent-liver efficiency network according to the principle line of "efficiency-property-pharmacology-target-protein interaction" under the background of the protein interaction network.
RESULTThe blood circulation-invigorating medicines could directly treat hepatoma by impacting protooncogene, cancer suppressor gene, cell apoptosis and anti-inflammation, and indirectly treat hepatoma by resisting coagulation and adhesion, regulating local blood circulation, preventing cancer cell metastasis and enhancing the tissues' sensitivity to the anticancer drugs. Among the active ingredients of safflower screened based on the blood circulation-invigorating network targets, carthamin yellow, quercetin and luteolin have been proved to have the anti-hepatoma effect in literatures, which indicated the reliability of this study's results and the purpose of the efficiency network.
CONCLUSIONThe efficiency network is an effective method for revealing the TCM's mechanism, and lays a foundation for discovering key active ingredients of TCMs for treating specific diseases.

To propose a formula method of medicated diet based on medicinal property combination patterns in this paper under the context of lack of innovation in medicated diets. By analyzing the property combination patterns of traditional Chinese medicine and commonly used foods recorded in the pharmacopoeia, medicated diet formulae were optimized by using the greedy algorithm, with the property combination patterns of classical formulae based on the syndrome differentiation and treatment. In this paper, the Baihu Rensheng decoction, which is a classical formula for treating lung and stomach heat-derived diabetes, was taken for example in the formula design. As a result, totally 18 medicated diet formulae were developed and proved to be rational in the analysis on traditional Chinese medicines and nutriology. This method expands the way of thinking for personalized diet therapies and provides theoretical basis the industrial development and clinical application of medicated diets.

At present, studies on traditional Chinese medicine (TCM) properties are mostly restricted to a single or two kinds of medicinal properties, but deviated from the holism of the theoretical system of TCMs. In this paper, the characteristics of pharmacological effects of different property combinations of TCMs distributing in the stomach meridian were take as the study objective. The data of properties of TCMs distributing in the stomach meridian was collected from the Pharmacopoeia of the People's Republic of China (2005). The data of pharmacological effects of TCMs distributing in the stomach meridian was collected from all of literatures recorded in Chinese Journal Full-text Database (CNKI) since 1980, Science of Chinese Materia Medica (Yan Zhenghua, People's Medical Publishing House, 2006) and Clinical Science of Chinese Materia Medica (Gao Xuemin, Zhong Gansheng, Hebei Science and Technology Publishing House, 2005). The corresponding pharmacological effects of property combinations of TCMs distributing in the stomach meridian was mined by the method of association rules. The results of the association rules were consistent with the empirical knowledge, and showed that different medicinal property combinations had respective pharmacological characteristics, including differences and similarities in pharmacological effects of different medicinal property combinations. Medicinal property combinations with identical four properties or five tastes showed similar pharmacological effects; whereas medicinal property combinations with different four properties or five tastes showed differentiated pharmacological effects. However, medicinal property combinations with different four properties or five tastes could also show similar pharmacological effects. In this study, the medicinal property theory and the pharmacological effects of TCMs were combined to reveal the main characteristics and regularity of pharmacological effects of TCMs distributing in the stomach meridian and provide a new way of thinking and method for revealing the mechanism action of TCMs distributing in the stomach meridian and discovering the pharmacological effects of TCMs distributing in the stomach meridian.
