The Role and Intervention of TGF-β in Abdominal Radiation Injury

This project aims to investigate the relationship between radiation-induced the relationship between elevated peripheral blood TGFβ and complications of radiotherapy,and to analysis of changes in peripheral blood TGFβ levels after abdominal radiotherapy and its relationship with radiotherapy complications.Simultaneously,Patients who underwent abdominal radiotherapy were given captopril (sustained release) to block TGFβ,Whether it can reduce peripheral blood TGFβ levels and reduce radiotherapy complications,to explore the protective effect of blocking TGFβ secretion on normal tissues after radiotherapy.
