TNF-α, IL-6 and IL-10 in serum. Compared to the C group, TNF-α, IL-6 and IL-10 in the S and SV groups were significantly increased, P < 0.05. VNS could reduce TNF-α and IL-6 in serum significantly, compared to the S group, P < 0.05. VNS did slightly raised IL-10 in serum, but there was no significant difference between both of them. *P < 0.05, comparing to the C group, #P < 0.05 comparing to the SV group
