摘要:

在2021年世界卫生组织发布的《世界听力报告》中,新生儿高胆红素血症被认定为感音神经性聋的主要风险因素之一,可导致包括听觉中枢在内的多系统神经损伤。胆红素是血红素的生理代谢产物,目前对胆红素基本生理代谢转运途径已有了充分认识。但新生儿高胆红素血症发病率仍处于较高水平,严重高胆红素血症会影响新生儿神经系统发育,甚至有致残风险。近20年来,上海交通大学医学院附属第六人民医院耳鼻咽喉头颈外科神经电生理研究团队在国际上率先开展了胆红素对神经元兴奋性的研究,揭示了胆红素对一系列离子通道与受体的作用,阐述了胆红素所致中枢损害的兴奋毒性机制,探索了潜在的拮抗药物。该文结合文献回顾与上述团队的研究成果,阐述了胆红素对中枢神经系统的作用及其机制,探讨了胆红素与胶质细胞在内的神经网络交互以及胆红素的潜在益处。其中胆红素毒理作用机制复杂,包括高浓度胆红素对突触结构、离子通道及受体、脂质双分子层胞膜及能量代谢等广泛的调控作用。该综述为更好地认识与防治胆红素神经毒性提供了理论支撑。

Abstract:

In the World Hearing Report published by the World Health Organization in 2021, neonatal jaundice hyperbilirubinemia is identified as one of the major risk factors for sensorineural deafness, which can lead to multisystem neurological damage, including the auditory center. Bilirubin is a physiological metabolite of heme, and the basic physiological metabolic transport pathways of bilirubin have been fully understood. But the incidence of neonatal hyperbilirubinemia is still at a high level. Severe hyperbilirubinemia seriously affects neonatal neurological development, and even has a risk of disability. In the past 20 years, this electrophysiology research team of the Department of Otolaryngology Head and Neck Surgery, Shanghai Sixth People's Hospital, Shanghai Jiao Tong University School of Medicine (Sixth Hospital for short) has been the first in the world to conduct studies on the excitability of bilirubin on neurons, reveal the effects of bilirubin on a series of ion channels and receptors, elaborate the excitotoxic mechanism of bilirubin-induced central damage, and explore potential antagonistic drugs. This paper combined previous studies with the findings of the electrophysiology research team of the Sixth Hospital to describe the effects of bilirubin on the central nervous system and its mechanisms, and discuss the interaction between bilirubin and glial cells and the potential benefits of bilirubin. The mechanisms of bilirubin's toxicological effects are complex and include a wide range of regulatory effects of high bilirubin concentrations on synaptic structures, ion channels and receptors, lipid bilayer membranes and energy metabolism. This review aims to provide theoretical support for better understanding and prevention of bilirubin neurotoxicity.

Key words: bilirubin, central nervous system, excitotoxicity, ion channel, receptor
