Comparison of miRNA cytokine levels between the two groups ($\overline{x}\pm s$).

Group	miRNA-124		miRNA-21		miRNA-203
	Before treatment	After treatment	Before treatment	After treatment	Before treatment	After treatment
Observation group (n = 42)	2.31 ± 0.85	5.06 ± 1.87a	2.35 ± 0.42	1.44 ± 0.52a	3.83 ± 0.62	1.40 ± 0.36a
Control group (n = 42)	2.34 ± 1.03	4.03 ± 1.13a	2.39 ± 0.62	1.78 ± 0.70a	3.80 ± 0.57	2.41 ± 0.58a
χ 2	0.163	3.058	0.281	2.478	0.204	9.544
P	0.871	0.003	0.779	0.015	0.839	<0.001

Note: compared with before treatment in the same group, ^aP < 0.05.
