带状疱疹后遗神经痛疼痛矩阵的研究进展

Research pregress in pain matrix of postherpetic neuralgia

带状疱疹后遗神经痛(PHN)是一种典型的慢性神经性疼痛综合征,外周和中枢神经系统作用机制均被认为参与了PHN,但中枢神经系统相关脑网络结构和功能尚未完全阐明,限制了临床镇痛药物及其他干预策略的研究。近年来,疼痛矩阵相关脑网络的研究有助于揭示疼痛的中枢神经系统调节机制,但PHN疼痛矩阵的研究报道较少。现就近年关于PHN疼痛矩阵的研究进行综述,回顾性分析疼痛相关具体脑区的功能及结构变化,旨在为探索高效靶向的镇痛治疗提供新的思路。

Postherpetic neuralgia(PHN) is a typical chronic neuropathic pain syndrome.Both peripheral and central nervous system mechanisms are believed to be involved in PHN,but the central nervous system-related brain network structure and function are not yet fully elucidated,limiting the study on the clinical analgesic drugs and other intervention strategies.In recent years,the research on pain matrix-related brain networks has helped to reveal the central nervous system regulation mechanism of pain,but there are few reports on the PHN pain matrix.This review summarizes the recent studies on the PHN pain matrix,retrospectively analyzes the functional and structural changes in specific pain-related brain regions,in order to provide the new insights for exploring the effective targeted analgesic treatments.
