研究目的:

通过临床不良事件及实验室指标观察,评价益生菌对预防和改善前列腺癌病人放射性肠炎的有效性,评价益生菌对放疗病人肠道菌群及其代谢产物、淋巴细胞亚群、细胞因子等指标的影响。  

Objectives of Study:

Through the observation of clinical adverse events and laboratory indicators, the effectiveness of probiotics in preventing and improving radiation enteritis in prostate cancer patients was evaluated, and the effects of probiotics on intestinal flora and its metabolites, lymphocyte subsets, cytokines and other indicators of radiotherapy patients were evaluated.
