Abstract:【Objective】To investigate the correlation between plasma microRNA-21 (miR-21) ,peripheral blood mononuclear cell helper T cell subsets 17 (Th17) cells and regulatory T cells (Treg) in patients with ulcerative colitis. 【Methods】 A total of 102 patients with ulcerative colitis (observation group) admitted to our hospital from August 2017 to December 2019 were selected,and 114 healthy volunteers (control group) who underwent physical examination in our hospital at the same time were selected. The levels of miR-21 in plasma were detected by real-time fluorescent quantitative PCR (qRT-PCR),Th17 cells and Treg cells were detected by flow cytometry,and the levels of interleukin-17 (IL-17) and transforming growth factor-β(TGF-β) in plasma were detected by enzyme-linked immunosorbent assay (ELISA),levels of interleukin-10 (IL-10) and interleukin-21 (IL-21); the correlation between plasma inflammatory factor levels and miR-21,Th17/Treg levels in patients with ulcerative colitis,and the factors affecting the occurrence of ulcerative coliti were analyzed. 【Results】 The levels of miR-21,Th17 cells and Th17/Treg in the observation group were higher than those in the control group,and the levels of Treg cells were lower than those in the control group (P<0.05). The levels of IL-17 and IL-21 in the observation group were higher than those in the control group,The level of TGF-β and IL-10 was significantly lower than that of the control group (P<0.05). Pearson analysis showed that the levels of miR-21 and Th17/Treg in patients with ulcerative colitis were positively correlated (r=0.598,P<0.05),and the levels of miR-21 and Th17/Treg were positively correlated with the levels of IL-17 and IL-21,and was negatively correlated with the level of TGF-β and IL-10 (P<0.05). Logistic regression analysis showed that miR-21 and Th17/Treg were independent risk factors for ulcerative colitis (P<0.05). TGF-β was the protective factor of ulcerative colitis (P<0.05). 【Conclusion】 Patients with ulcerative colitis have a serious imbalance of Th17/Treg,and the imbalance of Th17/Treg may be closely related to the level of miR-21.
