Effect of different frequencies of EAS of ST36-GB34 on expression of M1 and M2 AChR mRNA and proteins in the hippocampus in neuropathic pain rats (mean ± SD, n = 6 in each group); a M1 AChR mRNA, b M1 AChR protein; c M2 AChR mRNA, d M2 AChR protein; *P < 0.05, vs the normal group; #P < 0.05, vs the model group; ^P < 0.05, vs the 2 Hz EAS group; \(^\bullet\)P < 0.05, vs the 2/15 Hz EAS group
