Abstract: Irradiation-induced intestinal injury is a common complication caused by radiotherapy of abdominal and pelvic malignant tumors, which seriously affects the quality of patients’ life. It has been reported that Sijunzi Decoction (Four Noble Drugs Decoction) showed a protective effect on BALB/c mice after irradiation. To further explore the role of Sijunzi Decoction (Four Noble Drugs Decoction) in intestinal radiation damage, in this paper, human intestinal epithelial cells(HIEC-6)was used as the subject to investigate the protective effects of Sijunzi Decoction (Four Noble Drugs Decoction) on radiation damage. The experimental results showed that 0.95 mg/mL Sijunzi Decoction (Four Noble Drugs Decoction) could repair radiation damage on HIEC-6, reduce apoptosis, and slow down cell cycle block. The mechanism of Sijunzi Decoction (Four Noble Drugs Decoction) reducing radiation damage was related to the regulation on protein expression of Bcl-2 and γ H2AX. This work provided a reference for the treatment of radiation-induced intestinal injury by using Sijunzi Decoction (Four Noble Drugs Decoction).

Key words: Sijunzi Decoction (Four Noble Drugs Decoction), ionizing radiation, radiation protection, human intestinal epithelial cells
