Abstract:Objective To explore the prevention effect of modified Gegen Qinlian decoction for retention enema combined with Shenling Baizhu powder on radiation enteritis of cervical cancer.Methods According to random number table method, 280 patients with radiation enteritis of cervical cancer admitted to Sichuan Integrative Medicine Hospital were divided into Chinese medicine treatment group (140 cases, oral western medicine + modified Gegen Qinlian decoction for retention enema combined with Shenling Baizhu powder) and western medicine treatment group (140 cases, oral Western medicine + western medicine for retention enema) between October 2020 and October 2022. The differences in grading of RTOG radiation injury and Sherman, intestinal floras (Lactobacillus, Bifidobacteria, Escherichia coli), immune indexes (NK+, CD4+, CD8+, CD4+/CD8+), expressions of miR-122-5p and miR-21-3p, scores of QLQ-CR38 and ECOG, incidence of adverse events and recurrence rate between the two groups were compared.Results The grading of RTOG radiation injury and Sherman grading were lower in Chinese medicine treatment group than in western medicine treatment group (P<0.05). After treatment, counts of Lactobacillus and Bifidobacteria, levels of NK+ and CD4+, CD4+/CD8+, and QLQ-CR38 score were increased in both groups, which were higher in Chinese medicine treatment group than in western medicine treatment group (P<0.05), while count of Escherichia coli, CD8+ level, relative expression levels of miR-122-5p and miR-21-3p, and ECOG score were decreased, which were lower in Chinese medicine treatment group than in western medicine treatment group (P<0.05). There was no significant difference in the incidence of enema-related adverse eavents between the two groups (P>0.05), but recurrence rate of radiation enteritis was lower in Chinese medicine treatment group than in western medicine treatment group (P<0.05).Conclusion Modified Gegen Qinlian decoction for retention enema combined with Shenling Baizhu powder on basis of western medicine can effectively prevent radiation enteritis of cervical cancer, improve intestinal floras, immune function and quality of life.
