Changes of IL-6, TNF-α, and IL-1β in the hippocampus ($\stackrel{-}{x}\pm s$, ng/ml).

Groups	IL-6	TNF-α	IL-1β
Sham group	0.305 ± 0.019	0.118 ± 0.022	0.223 ± 0.021
Model group	0.331 ± 0.015a	0.170 ± 0.012a	0.336 ± 0.026a
EA group	0.372 ± 0.011ab	0.148 ± 0.020a	0.279 ± 0.037ab

The protein levels of IL-6, TNF-α, and IL-1β were determined by ELISA. Compared with the sham group, ^aP < 0.05; compared with the model group, ^bP < 0.05.
