Numerous studies have shown that hepatitis B virus and its products, HBV integration, and mutation can induce HCC. However, the molecular mechanisms underpinning the regulation of HCC induced by HBV remain unclear. Methods We downloaded 2 gene expression profiling datasets, of HBV and of HCC induced by HBV, from the gene expression omnibus (GEO) database. Differentially expressed genes (DEGs) between HCC and HBV were identified to explore any predisposing changes in gene expression associated with HCC. DEGs between HCC and adjacent healthy tissues were investigated to identify genes that may play a key role in HCC. Any overlapping genes among these DEGs were included in our bioinformatics analysis. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses of overlapping genes were performed and hepatitis B enable a systematic understanding of the molecular mechanisms of HCC reliant on hepatitis B virus.Background This study will examine the effects of artemisinin on proliferation and apoptosis of human liver cancer HepG2 cells (HLCHG-2C). Methods This study will systematically retrieve potential literatures in MEDLINE, Scopus, Web of Science, Cochrane Library, EMBASE, WANGFANG, and China National Knowledge Infrastructure from their initiation to the February 29, 2020. There are not limitations related to the language and publication time. All case-controlled studies (CCSs) or randomized controlled studies (RCSs) will be included in this study which investigated the effects of artemisinin on proliferation and apoptosis of HLCHG-2C. Two independent investigators will examine searched records, collect data from included studies, and will identify their methodological quality. Any diverg
