Fig. 1From: Membrane protein Nav1.7 contributes to the persistent post-surgical pain regulated by p-p65 in dorsal root ganglion (DRG) of SMIR rats model a-d The PWT result showed that persistent postoperative pain can be evoked through prolonged tissue retraction, consistent with the previously reported. Incision group (incision), SMIR group (incision plus retraction). (**P < 0.01, ***P < 0.001, vs incision group, n = 8)Back to article page
