Methods: Mice were exposed to 3% dextran sulfate sodium (DSS) for 5 days and followed by water for 4 weeks.

Mice were divided into six groups: control group that were allowed to drink only water, injury group that exposed to 3%DSS for 5 days and recover groups which drunk water for 1,2,3,4 weeks after DSS removed. General health condition was recorded daily. Related markers of apoptosis and proliferation were detected. The expression of TGF-β and p-Smad3 were measured to observe the change of TGF-β signaling pathway in this process. Results: The disease activity index of mice was increased after DSS treatment and returned to nomal at 2 weeks of DSS removed. The histological

score was increased significantly at injury group and began to decrease at 2 weeks of recovery. The apoptotic index was risen to the maximal level at injury group and came back to nomal level at 3 weeks. However, the proliferation index was reduced PD-1/PD-L1 inhibitor drugs to the minimal level at injury group, then started to increase to reach at the peak at 3 weeks. TGF-β expression was increased at all MCE of the experimental group, while the activation of Smad3 was inhibited at injury group, the began to be reactivated at 1 week after DSS removal. Conclusion: Smad3 phosphorylation promotes the repair of colonic mucosa of ulcerative colitis in mice. Key Word(s): 1. ulcerative
