下丘脑室旁核在针刺改善心脏功能中的作用*

经脉脏腑与脑之间的联系近年来被广泛关注。既往研究已经证实，针刺可明显调节心脏功能，其作用机制与神经系统的调控密切相关。下丘脑室旁核（PVN）是参与内脏功能调节的重要神经核团，学者们围绕针刺调节心脏功能的神经机制开展了大量研究，文中从针刺调节PVN神经元活动、神经递质释放、减少PVN内炎性细胞因子表达、降低应激反应、调控自主神经活动等方面探讨PVN在针刺调节心脏功能中的作用机制，以期为进一步揭示针刺效应的神经调控机制奠定基础。

The Role of Paraventricular Nucleus of Hypothalamus in Improving Cardiac Function by Acupuncture

The connection between meridians and viscera and brain has been widely concerned in recent years. Previous studies have confirmed that acupuncture can significantly regulate heart function, and its mechanism of action is closely related to the regulation of the nervous system.The hypothalamic paraventricular nucleus (PVN) is an important nerve nucleus involved in the regulation of visceral function. Scholars have carried out a lot of research on the neural mechanism of acupuncture regulating heart function.This article explores the mechanism of PVN in the regulation of cardiac function by acupuncture from the aspects of acupuncture regulating PVN neuron activity, neurotransmitter release, reducing the expression of inflammatory cytokines in PVN, reducing stress response, and regulating autonomic nerve activity, in order to lay the foundation for further revealing the neural regulation mechanism of acupuncture effect.
