Abstract Objective To research the clinical effect and mechanism of Qingchang Decoction combined with Mesalazine on ulcerative colitis patients with syndrome of blood stasis due to exuberant heat. Methods A total of 60 patients of active ulcerative colitis with syndrome of blood stasis exuberant from Zhangjiagang Hospital Affiliated to Nanjing University of Chinese Medicine were divided into treatment group (Qingchang Decoction and Mesalazine Sustained-release Granules) and control group (Mesalazine Sustained-release Granules) according to the random number table method, with 30 cases in each group. Three months after treatment, the clinical efficacy, traditional Chinese medicine symptom score, Mayo score, and endoscopic mucosal healing rate of each group were compared, immunohistochemical expression of tumor necrosis factor receptor-associated factor (TRAF) 6, nuclear transcription factor κB (NF-κB) and immunofluorescence staining of Toll-like receptors (TLR4) in mucosal tissues of two groups were analyzed. Results The clinical effect of the treatment group was better than that of the control group (P < 0.05). After treatment, the single scores and total score of traditional Chinese medicine syndrome in both groups were lower than those before treatment, and those in the treatment group were lower than those in the control group (P < 0.05). After treatment, Mayo scores in both groups were lower than those before treatment, and that in the treatment group was lower than that in the control group (P < 0.05). After treatment, the mucosa healing rate in the treatment group was higher than that in the control group (P < 0.05). After treatment, the expression of TRAF6 and NF-κB in both groups were lower than those before treatment, and the expression levels of TRAF6 and NF-κB in treatment group were lower than those in control group (P < 0.05). After treatment, the expression of immunofluorescence TLR4 in both groups were lower than those before treatment, and that in the treatment group was lower than that in the control group (P < 0.05). Conclusion Qingchang Decoction combined with Mesalazine can effectively improve the clinical symptoms, intestinal mucosal healing of active UC patients with syndrome of blood stasis due to exuberant heat. The anti-inflammatory effect of Qingchang Decoction may be achieved by inhibiting the TLR4/TRAF6/NF-κB signaling pathway.
