Abstract:

Objective

To investigate the expression levels of miRNA22-3p and miRNA223-3p in gouty arthritis patients and the regulatory mechanism of inflammatory immune response.

Methods

The data of 80 gout patients who met the gouty diagnosis creteria and treated in the First Hospital of Qinhuangdao from January 2020 to January 2021 were retrospectively analyzed. Other 80 healthy patients who underwent rountine health check-up during the same period without obvious abnormality in clinical indicators were enrolled as the control group. Exclusion criteria: the patients with severe diseases of the vital organs and systems; patients who used hormone drugs in the past three months; secondary gouty arthritis caused by other diseases; dryg induced gouty arthritis attacks; mental disorders. The observation group met the diagnostic criteria of gout. Independent sample t test was used to compare the differences in miRNA22-3p, miRNA223-3p, infla-mmatory response and immune indicators between the two groups. Pearson correlation analysis was applied for the relationship between inflammatory indicators and miRNA22-3p as well as miRNA223-3p.

Results

Expression levels of miRNA22-3p and miRNA223-3p in the observation group were (4.01±1.03) and (1.51±0.12), respectively, which were significantly higher than those in the control group [(1.12±0.26) and (0.62±0.20)] (t=24.333, 34.130, both P<0.05). The levels of IL-1β, TNF-α and IL-6 in the observation group were (57.77±7.24), (24.04±4.24) and (49.27±3.72), respectively, which were significantly higher than those in the control group. (42.27±3.31), (18.07±4.17), (39.75±3.73), respectively (t=17.415, 8.979, 16.164, all P<0.05). The levels of monocyte chemoattractant protein (MCP)-1, thymus and activation regulated chemokine (TARC), eotaxin-2 in the observation group were(106±12), (215±13), (347±11) which were higher than those in the control group [(72±11), (159±12), (317±12)](t=18.095, 29.356, 16.713, all P<0.05). Pearson correlation analysis showed the expressions of miRNA22-3p and miRNA223-3p were positively correlated with MCP-1, TARC, eotaxin-2, IL-1β, TNF-α and IL-6 (r=0.609, 0.659, 0.545, 0.610, 0.551, 0.571, 0.684, 0.668, 0.671, 0.542, 0.534, 0.458, all P<0.05).

Conclusion

The expression levels of mirNA22-3p and mirNA223-3p in gouty arthritis patients are significantly increased, which are positively correlated with inflammation and immune response.
