Abstract:
Objective:To investigate the expression and its clinical significance of cydooxygenase-2(COX-2)and tumor necrosis factor-alpha(TNF-α)in mucosal tissues in elderly ulcerative colitis(UC)patients with arthritis.Methods:A total of 164 active(observation group)and 50 non-active(control group)UC patients with arthritis were admitted in our hospital from April 2016 to March 2019.Diagnostic criteria of UC and its severity were based on Consensus on the Norms for Diagnosis and Treatment of Inflammatory Bowel Disease in China(2007). The expressions of COX-2 and TNF-alpha in mucosal tissues were detected and compared between the two groups.Patients in the observation group were re-grouped according to the severity of ulcer lesion and Kellgren-Lawrence(K-L)score of arthritis.Based on severity of ulcer lesion and Kellgren-Lawrence(K-L)score of arthritis, the patients in observation group were re-grouped intoⅠ, Ⅱ, Ⅲ, Ⅳ subgroups, among those subgroups the expressions of COX-2 and TNF-alpha in mucosal tissues were compared.Results:The expressions of COX-2 and TNF-alpha in mucosal tissue were higher in the observation group than in the control group( P<0.05), and were increased along with the increased severity of UC and the K-L grade of arthritis( P<0.05). The differences in above expressions had statistical significance among patients with different severity of ulcer and different K-L grade of arthritis.The expressions of COX-2 and TNF-alpha in mucosal tissues were positively correlated with the severity of ulcer( r=0.491 and 0.627, P<0.05 or 0.01)and K-L grade of arthritis( r=0.438 and 0.597, P<0.05 or 0.01). Conclusions:The expressions of COX-2 and TNF-alpha in mucosal tissues are positively correlated with the severity of ulcer and K-L grade of arthritis in elderly UC patients with arthritis.The detection of COX-2 and TNF-alpha levels is helpful to evaluate the disease severity.
