B1. The TNF-α level of rats in each group measured by ELISA.
	Sham	HI	HI+S	F value	DF
TNF-α (ng/L)	24.1±2.8	62.4±5.9*	48.1±4.5**	107.2	2

One-way ANOVA was used to compare the mean difference among the three groups. Tukey’s multiple comparisons test was used for post hoc test.

^*p<0.001 between sham group and HI group,

^**p<0.001 between HI group and HI+S group.
