The control group was given mesalazine sustained-release tablets orally, while the treatment group was given Baitou Weng Decoction and mesalazine sustained-release tablets orally. The treatment period was 30 days and the patients were followed up for 3 months. After treatment, the clinical efficacy, quality of life, immune function and serum inflammatory factors of the two groups were observed.Results: The effective rate of treatment group (90.47%) was higher than that of control group (73.81%) (P<0.05);compared with before treatment, the scores of inflammatory bowel disease quality of life questionnaire scale in both groups were significantly improved (P<0.05), and the difference between the two groups was significant (P<0.05);after treatment, the plasma CD4+/CD8+ ratio and NK+ levels in both groups were significantly higher than those before treatment (P<0.05), and the treatment group was changed. The serum levels of tumor necrosis factor-α, interleukin-17 and interleukin-23 were significantly decreased in both groups after treatment (P<0.05), and the improvement was more significant in the treatment group (P<0.05). No significant adverse reactions were observed in the treatment group.Conclusions: Modified Baitou Weng Decoction combined with mesalazine in the treatment of heat-toxic and incandescent ulcerative colitis can significantly improve the clinical efficacy, improve the quality of life of patients, effectively regulate the expression level of serum inflammatory factors in ulcerative colitis patients, promote the recovery of patients' immune function, and have high drug safety.展开更多
