Correlation between expression of miR-223 and clinical and lab parameters of patients with SLE (*p < 0.05, NS means none sense). (A) MiR-223 was up-regulated in neutrophils of patients with SLE (n = 12) compared to healthy controls (n = 12). Expression of miR-223 in SLE patients with or without skin involvement (B), arthritis (C), lupus nephritis (D), leukopenia (E), anti-dsDNA (+) (F), anti-Sm (+) (G) were compared. MiR-223 expression had a positive correlation with SLEDAI (p < 0.05) (H), and negative correlation with the levels of C3 and C4 (both p < 0.05) (I and J)
