7 Action mechanism of drugs for preventing and treating coronary heart disease based on biological networks ZHANG Yan-ling HUANG Ming-feng QIAO Yan-jiang * Research Center of Traditional Chinese Medicine Information Engineering Beijing University of Chinese Medicine Beijing China Abstract Coronary heart disease CHD related genes and targets as well as drug targets for preventing and treating CHD were taken as the study objects to build a CHD disease network and a drug action network preventing and treating CHD. Such topological characteristic parameters of the networks as degree distribution characteristic path length connectivity and heterogeneity were analyzed to verify the reliability of the networks. On that basis the intersection calculation was conducted for both networks to analyze the drug action mechanism of their sub-networks. The disease network are composed of nodes and sides while the drug action network preventing and treating CHD has nodes and sides. Both of their topological characteristic parameters showed scale-free small world structural characteristics. Two reaction pathways in the sub-networks calcitonin gene-related peptide and IL-6 activated JAK / STAT were taken as examples to discuss the indirect action mechanism for preventing and treating CHD. The results showed that the biological network analysis method combining the disease network and the drug action network is helpful to further studies on the action mechanism of the drugs and significant to the prevention and treatment of diseases.
