Observation of NETs in gastric mucosal and submucosal layers. )a): NETs marker expressions in the mucosal layer (× 40, scale bar = 20 µm), red indicates H3Cit, green indicates MPO, and blue indicates DAPI-stained nucleus; (b): Proportions with positive expression of H3Cit in the mucosal layer, bar: mean ± SE, n = 3; (c): Proportions with positive expression of MPO, bar: mean ± SE, n = 3; (d): Proportions with co-expression of MPO and H3Cit in the mucosal layer, bar: mean ± SE, n = 3. vs control group, ^**P < 0.01, ^*P < 0.05. (e): NETs marker expressions in the submucosal layer (× 40, scale bar = 20 µm), red indicates H3Cit, green indicates MPO, and blue indicates DAPI-stained nucleus; (f): Proportions with positive expression of H3Cit in the submucosal layer, bar: mean ± SE, n = 3; (g): Proportions with positive expression of MPO, bar: mean ± SE, n = 3; (h): Proportions with co-expression of MPO and H3Cit in the submucosal layer, bar: mean ± SE, n = 3. vs control group, ^*P < 0.05, ^**P < 0.01.
