Bletilla striata carbon dots with alleviating effect of DSS-induced ulcerative colitis

Ulcerative colitis (UC) is a type of inflammatory bowel disease (IBD) that significantly affected quality of life for patients. In this study, carbon dots based on Bletilla striata (BS-CDs) were synthesized by hydrothermal method and characterized by optical property analysis. In addition, the study measured the potential effect of BS-CDs on colonic histopathology and inflammation in dextran sulfate sodium (DSS)-induced ulcerative colitis. The results suggested that BS-CDs significantly increased colon length, improved colonic histopathology, and reduced the levels of pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6) in colitis mice. Taken together, BS-CDs alleviate clinical inflammation by blocking pro-inflammatory cytokines which were expected to be a potential agent for the treatment of colitis.
