Abstract:Objective: To investigate the expression and significance of serum decoy receptor 3, interferon-gamma and anti-cyclic citrullinated peptide antibodies in patients with rheumatoid arthritis. Methods: Seventy patients with rheumatoid arthritis admitted to our hospital from February 2017 to December 2017 were selected as observation group, and 65 healthy subjects who received health examination in our hospital during the same period were selected as control group. Fasting venous blood was collected from all subjects on the morning of the 2nd day after admission. The expression of serum decoy receptor 3, interferon-gamma and anti-cyclic citrullinated peptide antibody was detected. The changes and significance of serum decoy receptor 3, interferon-gamma and anti-cyclic citrullinated peptide antibodies in patients with rheumatoid arthritis were analyzed. Results: The serum levels of decoy receptor 3, interferon-gamma and anti-cyclic citrullinated peptide antibodies in the observation group were (4631.05 (+3180.24) pg/mL, (1341.23 (+482.94) pg/mL and (86.51 (+6.38) U/mL, respectively, while those in the control group were (481.53 (+150.07) pg/mL, (248.79 (+62.63) pg/mL and (45.41 (+8.35) U/mL, respectively, with statistical differences (P<0.05); Pearson correlation analysis showed that the serum levels of decoy receptor 3, interferon and anti-cyclic Cit Deception receptor 3, interferon-gamma and anti-cyclic citrullinated peptide antibody levels were positively correlated (r = 0.658, 0.744, P<0.05). Conclusion: The serum levels of decoy receptor 3, interferon-gamma and anti-cyclic citrullinated peptide antibodies in patients with rheumatoid arthritis were significantly increased, and the serum levels of decoy receptor 3, interferon-gamma and anti-cyclic citrullinated peptide antibodies were positively correlated, which could assist in the diagnosis of rheumatoid arthritis.
