Qijia Rougan decoction was modified from <jats:italic>Sanjiasan<\/jats:italic>, a traditional Chinese medicine (TCM) described in the \u201cWenyilun\u201d manuscript. Qijia Rougan decoction possesses hepatoprotective and antifibrotic effects for clinical applications. However, its underlying mechanisms remain largely unknown. In this study, fibrotic rats induced by carbon tetrachloride (CCl<jats:sub>4<\/jats:sub>) were treated with two doses of Qijia Rougan decoction. Histopathological and serum biochemical analyses were carried out to assess liver structure and function, respectively. High-performance liquid chromatography (HPLC) coupled with mass spectrometry (MS) was performed to identify bioactive compositions in Qijia Rougan decoction. Transcriptome analysis using mRNA-sequencing (mRNA-Seq) was used to explore the underlying mechanisms and verified by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting. Qijia Rougan decoction significantly attenuated CCl<jats:sub>4<\/jats:sub>-induced hepatic fibrotic injury, supported by promoted liver function and improved liver fibrosis. Eight main representative components originating from raw materials in the Qijia Rougan decoction were found to possess an antifibrotic role. Mechanistically, Qijia Rougan decoction regulated biological processes such as oxidation\u2013reduction, fatty acid metabolism, cell adhesion, and transforming growth factor beta (TGF\u03b2) signaling. We determined that Qijia Rougan decoction reversed the expression of inflammatory cytokines and inhibited the activation of fibrosis-related TGF\u03b2 signaling. It also reversed the deterioration of liver structure and function in rats induced by CCl<jats:sub>4<\/jats:sub>. Overall, Qijia Rougan decoction significantly mediated metabolism-associated processes, inhibited inflammatory reactions, and repressed fibrosis-related TGF\u03b2 signaling, which prevented liver fibrosis deterioration. Our study deepens our understanding of TCM in the diagnosis and treatment of liver fibrosis.<\/jats:p>","DOI":"10.3389\/fphar.2022.911250","type":"journal-article","created":{"date-parts":[[2022,7,1]],"date-time":"2022-07-01T04:47:16Z","timestamp":1656650836000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Hepatoprotective Efficacy and Interventional Mechanism of Qijia Rougan Decoction in Liver Fibrosis"],"prefix":"10.3389","volume":"13","author":[{"given":"Xiao-Feng","family":"Chen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yumei","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shaoxiu","family":"Ji","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Quansheng","family":"Feng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Han","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2022,7,1]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"199","DOI":"10.1002\/ptr.5957","article-title":"Selected Hepatoprotective Herbal Medicines: Evidence from Ethnomedicinal Applications, Animal Models, and Possible Mechanism of Actions","volume":"32","author":"Ali","year":"2018","journal-title":"Phytother.
