To analyze the differential expression profiles of qi stagnation and blood stasis syndrome (QSBSS) withbioinformatics method, so as to explore the possible biological basis and mechanism of QSBSS. A total of 331 papers on the study of QSBSS were retrieved in CNKI and PubMed databases, and the basic information as well as RNA differentialexpression profiles were extracted and summarized. The gene function was annotated by GeneCards database, and the Database for Annotation, Visualization and Integrated Discovery (DAVID) was used for enrichment analysis on the biological function and signaling pathway of differentially expressed RNA. The miRNA- target interactions module,miRNA-lncRNA interactions module, miRNA-circRNA interactions module in starBase v2. 0 and the Multiple proteinsmodule in STRING Version 10. 5 were utilized to establish the ceRNA-mRNA-protein interaction network of QSBSS.The literature analysis showed that 41 studies reported the results of QSBSS on omics, in which the number of proteinexpression studies was the most, followed by studies on mRNA, SNP, miRNA, DNA methylation, lncRNA, and circRNA.GO function enrichment analysis of differential expression profiles showed that, firstly, in biological process, QSBSSrelated genes are mainly relevant to cell response to organic cyclic compounds, negative regulation of transcription,negative regulation of neuronal apoptosis gene expression, and inflammatory response. Secondly, in cellular component,QSBSS related genes are mainly relevant to protein complex, nucleoplasm and cell surface. Thirdly, in molecularfunction, QSBSS related genes are mainly relevant to identifiable protein binding, enzyme binding, and the gene bindingin transcriptional regulatory region. Among of them, inflammatory response is the most relevant to the basic biologicalresearch on QSBSS. KEGG signal pathway analysis showed that the signal pathway related to QSBSS related genesincluded proteoglycans in cancer, tumor necrosis factor (TNF) signaling pathway, pathways in cancer, and human Tlymphocyte virus infection. Among of them, the TNF signaling pathway is the most relevant to the basic biologicalresearch on QSBSS. The genes related to QSBSS involve multiple biological functions and multiple signaling pathways.Among of them, the inflammatory response and the TNF signal pathway are the most relevant.
