Gap junctions are specialized transmembrane channels that enable the direct exchange of materials and transfer chemical or electrical signaling between adjacent cells, thus maintaining cellular homeostasis. In the nervous system, gap junction chan-nels not only mediate intercellular coupling between neurons and between glial cells, but also can be involved in secondary dam-age under pathological conditions. Recently, some studies have shown that gap junctions play an important role in neuropathic pain caused by nervous system damage. Research on the role of gap junctions in neuropathic pain can contribute to a deeper un-derstanding of the pathogenesis of neuropathic pain, providing a new research direction for the treatment of neuropathic pain.

AIM: To investigate the feasibility of early reversal of vecuronium with neostigmine. METHODS: 48 patients (ASA class I or II) scheduled for elective surgery undergoing general anaethesia were randomly assigned to vecuronium group (n=16) and vecuronium+ neostigmine group (n=32). Furthermore, the latter was divided into two groups according to the time of reversal. In vecuronium+ neostigmine group 1, the patients received neostigmine antagonization within 10 min after vecuronium administration,and in vecuronium+neostigmine group 2, time of reversal within 11-30 min after vecuronium administration. All patients received vecuronium 1.5 mg?kg -1 after general anesthesia. Neostigmine 0.05 mg?kg -1 +atropine 0.5 - 1.0 mg+saline 8 ml was administered to vecuronium+ neostigmine group and recovery was compared with that of vecuronium patients who received 8 ml saline. The time from vecuronium administration to recovery of?TOF? 0.25 ?and? 0.7 ?was recorded.?RESULTS: In vecuronium group, the recovery time to TOF 0.25 and 0.7 was ( 45.58 ? 8.88 ) min, and ( 67.59 ? 5.60 ) min, respectirely; in vecuronium+ neostigmine group 1,it was ( 23.45 ? 2.82 ) min, and ( 31.86 ? 3.36 ) min, respectirely; and in vecuronium+neostigmine group 2, it was ( 28.70 ? 4.13 ) min,and ( 38.86 ? 2.10 ) min, respectirely.
