Abstract: The mechanism of leukocyte elevation activity of Lvjiao Buxue granules was studied by establishing the active components-targets network and protein interactions network and analyzing the functions and pathways of targets. The main active ingredients of Lvjiao Buxue granules were obtained by TCMSP and literature excavation. Based on the DRAR-CPI, GeneCards and CoolGeN, the active components of Lvjiao Buxue granules were predicted and screened. Cytoscape software was used to construct the drug-active components-target network, and a protein database was constructed by using String database and Cytoscape software. The relation of the main active ingredients and targets were validated by Systems Dock Web Site. The GO and KEGG pathways involved in the targets were analyzed by DAVID databases. Using DisGeNET database to attribute the type of targets. The results showed that 49 active components and 89 targets of Lvjiao Buxue granules were involved. The network results showed that the composition of purine ribonucleosides, the regulation of cell death, especially the biological processes such as neutrophil and oxidative stress were mainly involved in the regulation of metabolic, cancer, tuberculosis, PI3K-Akt signaling and many other pathways to play its elevating leukocytes effect. This study reflects the characteristics of multi-components-multi-targets and multi-pathways of Lvjiao Buxue granules, which laid the foundation for further research into the mechanism of leukocyte elevation activity of Lvjiao Buxue granules.
