迷走背核复合体是针刺调节胃功能的关键核团？

Is dorsal vagal complex the key nucleus of acupuncture regulation of gastric function?

针刺治疗功能性胃肠疾病疗效显著,但其中枢机制不明确,目前研究主要聚焦在某些中枢核团,如迷走背核复合体(DVC)、中缝大核(NRM)、蓝斑(LC)、背侧网状亚核(SRD)、下丘脑室旁核(PVN)、小脑顶核(FN)、中央杏仁核(CeA)等。核团之间是否通过某种相互联系参与针刺调节胃功能尚不清楚。进一步整理相关文献发现中枢神经系统许多脑区或核团都与胃功能密切相关,如DVC、NRM、臂旁核(PBN)、LC、中脑导水管周围灰质(PAG)、小脑、PVN、弓状核(Arc)、海马、CeA等,这些核团相互之间大多数都有一定的纤维联系,其中以DVC为基本中枢,其他核团都直接或间接地通过DVC参与对胃功能的调控。针刺调节胃功能是否也以DVC为关键靶点,其他核团直接或间接与DVC形成某种神经环路参与针刺对胃功能的调控?如探讨CeA-DVC神经环路参与针刺调节胃功能的可能性。因此引入更先进的光遗传、化学遗传等技术,从神经环路角度以DVC为中心开展针刺调节胃功能的中枢机制的研究将成为下一步的重点,以实现运用现代神经科学技术阐释腧穴配伍的中枢整合机制。

Acupuncture has remarkable effects on treating functional gastrointestinal diseases, but its central mechanism is not clear. At present, the research has mainly focused on several central nuclei, such as the dorsal vagus complex(DVC), nucleus raphe magnus(NRM), locus coeruleus(LC), subnucleus reticularis dorsalis(SRD), hypothalamic paraventricular nucleus(PVN), cerebellar fastigial nucleus(FN), central amygdala(CeA), etc. It is not clear whether the nuclei are involved in acupuncture regulation of gastric function through certain interrelation. A further summary of related literature indicates that many brain regions or nuclei in the central nervous system are closely related to gastric function, such as DVC, NRM, parabrachial nuclei(PBN), LC, periaqueductal gray(PAG), cerebellum, PVN, arcuate nucleus(Arc), hippocampus, CeA, etc. Most of these nuclei have certain fiber connections with each other, in which DVC is the basic center, and other nuclei are directly or indirectly involved in the regulation of gastric function through DVC. Is DVC the key target in acupuncture regulation of gastric function? Does other nuclei have direct or indirect neural circuit with DVC to participate in the regulation of gastric function by acupuncture, such as the possibility of CeA-DVC neural loop in acupuncture regulating gastric function. Therefore, more advanced techniques such as photogenetics, chemical genetics should be introduced and the central mechanism of acupuncture on regulating gastric function with DVC as center, from the view of nerve loop, will become the focus of further research, which could explain the central integration mechanism of acupoint compatibility by modern neuroscience technology.
