Laboratory parameters showed statistically significant differences in plasma S100A1, NF-κB P65, and IL-6 among the AIS group, TIA group, and PE group (S100A1, (230.96 ± 39.37) vs (185.85 ± 43.24) vs (181.47 ± 27.39), P < 0.001; NF-κB p65, (3.99 ± 0.65) vs (3.58 ± 0.74) vs (3.51 ± 0.99), P = 0.001; IL-6, (13.32 ± 1.57) vs (11.61 ± 1.67) vs (11.42 ± 2.34), P < 0.001). The gene discussed is NFKB1; the disease is transient ischemic attack.
