Gegen Qinliantang Alleviates Ulcerative Colitis via Cell Signaling Pathways： A Review / 中国实验方剂学杂志

ABSTRACT

Gegen Qinliantang， a classic traditional Chinese medicine（TCM） compound， has been verified in modern research to possess various pharmacological effects such as anti-inflammation，anti-oxidative stress，protecting intestinal mucosal barrier， and regulating intestinal flora and immune response. Ulcerative colitis （UC） is a chronic idiopathic inflammatory disease involving the colorectal mucosa， which mainly results from genetic susceptibility， intestinal mucosal barrier damage， abnormal immune response， intestinal flora disturbance， and bile acid metabolism disorders. By reviewing the literature published in recent years， this paper sorted out the relevant pathways and mechanisms involved in the treatment of UC by Gegen Qinliantang to provide ideas for further clinical and basic research. This literature review uncovered that Gegen Qinliantang exerted the therapeutic effects against UC mainly via interleukin-6（IL-6）/Janus tyrosine kinase 2（JAK2）/signal transducer and activator of transcription 3（STAT3） signaling pathway， Toll like receptor 4（TLR4）/nuclear transcription factor-κB（NF-κB） signaling pathway，Notch signaling pathway， and matrix metalloproteinase-9（MMP-9）/p38 mitogen-activated protein kinase（p38 MAPK） signaling pathway. Gegen Qinliantang regulates the intercellular molecular transmission in multiple pathways to protect the intestinal mucosal barrier， adjust the immune response and anti-oxidative stress， and relieve UC， demonstrating the multi-target， multi-mechanism， and multi-pathway advantages of TCM compounds.
