Objective To explore the potential mechanism of Rhei Radix et Rhizoma-Persicae Semen in treatment of liver cirrhosis by network pharmacology. Methods With the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), the effective chemical components and target genes of Rhei Radix et Rhizoma-Persicae Semen were filtrated. Potential targets of active components were obtained through the Protein Database (UNIPROT). According to the TTD、GeneCard、PharmGkb、DrugBank and OMIM Databases, targets of liver cirrhosis were collected. The Cytoscape 3.7.2 software was used to construct the Rhei Radix et Rhizoma-Persicae Semen active components-liver cirrhosis-targets network. String platform was used to construct a protein-protein interaction (PPI) network. Gene ontology (GO) enrichment and Kyoto encyclopedia of genes and genomes (KEGG) signaling pathways analysed of screened target proteins were employed by R and Bioconductor software, and the top 30 of them were selected. Results A total of 29 bioactive components of Rhei Radix et Rhizoma-Persicae Semen could act on 22 potential targets of liver cirrhosis. Nine key therapeutic targets were collected such as TP53、MAPK3、HSP90 by the constructed PPI network. The enrichment analysis showed that the Rhei Radix et Rhizoma-Persicae Semen treatments for liver cirrhosis signal pathways including regulation of vasculature development and angiogenesis, epithelial cell proliferation, lipid metabolic process,response to oxygen levels and so on. Rhei Radix et Rhizoma-Persicae Semen anti-liver cirrhosis by changing biological related process such as microRNAs (miRNAs) in cancer, PI3K-Akt signaling pathway, hepatocellular carcinoma, hepatitis B. Conclusion Rhei Radix et Rhizoma-Persicae Semen had direct or indirect therapeutic effects on liver cirrhosis through regulating vasculature and angiogenesis, epithelial cell proliferation, regulation of lipid metabolic process and so on. The possible potential signal pathways including miRNAs in cancer, PI3K-Akt signaling pathway and so on.
