Changes in MMP‑2, MMP‑9, inflammation, blood coagulation and intestinal mucosal permeability in patients with active ulcerative colitis

Changes in matrix metalloproteinase (MMP)-2, MMP-9, inflammation, blood coagulation factors and intestinal mucosal permeability in patients with active ulcerative colitis (UC) were investigated. A total of 50 active UC patients treated in our hospital from January 2016 to December 2018 were selected as the UC group, whereas 50 normal subjects receiving physical examination were selected as the control group. Venous blood was drawn to detect the content of early predictors, C-reactive protein (CRP), follistatin-like protein 1 (FSTL1) and D-dimer in serum. The disease activity index (DAI) score was recorded in both groups, the levels of MMP-2 and MMP-9 were determined, and the inflammatory factors interleukin (IL)-1, IL-6 and tumor necrosis factor (TNF)-[alpha] were also detected. Moreover, the blood coagulation factors, platelet count, prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen level were detected, the content of lactulose (L) and mannitol (M) in the urine after oral administration of L and M test liquid was determined via high-performance liquid chromatography in both groups, and the L/M ratio was calculated. In UC group, the content of CRP, FSTL1 and D-dimer was significantly higher than that in the control group (P
