摘要:

单唾液酸神经节苷酯1是神经节苷脂的主要亚型,对中枢神经系统中具有神经保护作用,是否会抑制丙泊酚和瑞芬太尼相互作用在麻醉中对神经发育方面存在的不利影响?从新生SD大鼠海马组织中分离的神经干细胞分别加入瑞芬太尼(5,10,20ng/mL)、丙泊酚(1.0,2.5,5.0μg/mL)和/或单唾液酸神经节苷酯1(12.5,25,50μg/mL),见单唾液酸神经节苷酯1能逆转丙泊酚联合瑞芬太尼干预后BrdU阳性细胞数量的减少,神经干细胞增殖和分化过程中凋亡细胞比例的增加以及神经干细胞分化过程中细胞内钙离子浓度的降低,但不影响神经干细胞分化过程中β-tubulin阳性细胞和神经胶质酸性蛋白阳性细胞的比例。说明单唾液酸神经节苷酯1可能缓解丙泊酚联合瑞芬太尼对神经干细胞的破坏作用,对未成熟中枢神经系统具有保护作用。

Abstract:

Monosialoganglioside 1 (GM1) is the main ganglioside subtype and has neuroprotective properties in the central nervous system. In this study, we aimed to determine whether GM1 alleviates neurotoxicity induced by moderate and high concentrations of propofol combined with remifentanil in the immature central nervous system. Hippocampal neural stem cells were isolated from newborn Sprague-Dawley rats and treated with remifentanil (5, 10, 20 ng/mL) and propofol (1.0, 2.5, 5.0 μg/mL), and/or GM1 (12.5, 25, 50 μg/mL). GM1 reversed combined propofol and remifentanil-induced decreases in the percentage of 5-bromodeoxyuridine(+) cells and also reversed the increase in apoptotic cell percentage during neural stem cell proliferation and differentiation. However, GM1 with combined propofol and remifentanil did not affect β-tubulin(+) or glial fibrillary acidic protein(+) cell percentage during neural stem cell differentiation. In conclusion, we show that GM1 alleviates the damaging effects of propofol combined with remifentanil at moderate and high exposure concentrations in neural stem cells in vitro, and exerts protective effects on the immature central nervous system.
