Brief summary

The goal of this single - center, prospective, randomized controlled study is to assess the therapeutic effects of five - flavor sophora flavescens enteric - coated capsules on radiation - induced proctitis in patients who have undergone pelvic radiotherapy. The main question it aims to answer is: Does five - flavor sophora flavescens enteric - coated capsules treatment improve radiation - induced proctitis in these patients? Participants with radiation - induced proctitis following pelvic radiotherapy will be randomly allocated to either the trial group (receiving the capsules) or the control group (receiving conventional therapy). Assessments will be conducted to compare outcomes between the two groups.

Interventions

DRUGfive - flavor sophora flavescens enteric - coated capsules plus glutamine and warm - water sitz baths

Experimental group: If patients have rectal reactions, RTOG radiation - therapy toxicity grades \>2, plus FOB (+) or fecal calprotectin Fc\>150μg/g, they'll take five - flavor sophora flavescens enteric - coated capsules (4 capsules thrice daily for 8 weeks), plus glutamine and warm - water sitz baths.

DRUGglutamine and warm - water sitz baths

If patients have rectal reactions, RTOG radiation - therapy toxicity grades \>2, plus FOB (+) or fecal calprotectin Fc\>150μg/g, they'll use only glutamine and warm - water sitz baths.
