在考察针刺穴位治疗作用的基础上，根据现有的实验事实，将人体经络的观念和经改进后的神经-内分泌-免疫系统的观念统一起来，提出人体经络是具有敏感节点和功能连接的神经-内分泌-免疫网络的假说。人体经络的复杂网络不仅是遍及全身的系统，而且可以通过敏感节点及其功能连接对身体起调控作用。

The therapeutic effects of acupuncture are well known. Based on previous and existing experimental results, we combine the basic theory of acupunture and meridian with that of neuroendocrine immune system and propose a new tentative theory of human meridian. We hypothesize that the human meridian system consists of neuroendocrine immune networks with numerous sensitive nodes and their functional connections. The complex meridian networks are then not only spreading over the whole human body but also taking effects on body through those sensitive nodes and their functional connections.
