From animal experiments and clinical trials, we can think that acupuncture of Nei-Kuan (EH-6) is effective in the control of some vegetative functions. We have tried to determine the real reach of these assumptions by means of simple quantitative measurement methods, such as detection of cardiac frequency and systolic and diastolic blood pressure, and the sympathetic electrical response. The experiments were performed on 29 healthy volunteers. Basal values of these parameters were recorded, and also after orthodox Nei-Kuan acupuncture, non-acupunctural point puncture, supine lying by 15 min, Chü-Tze (EH-3) acupuncture and bipolar electrical stimulus of the median nerve at the Nei-Kuan level in the wrist. Such conditions were designed to evaluate non-specific puncture, repose and direct median nerve stimulation influences in the effects of Nei-Kuan acupuncture. We conclude that Nei-Kuan acupuncture strongly inhibits sympathetic tone, with reduction of cardiac frequency, systolic blood pressure and an important reduction of the amplitude of the sympathetic electrical response; the latency of the electrical response was also prolonged. Some weak effects on blood pressure and cardiac frequency were observed also, as non-specific effects of puncture and median nerve stimulation. From previous anatomical data, we hypothesize that the level of such actions is suprametameric, with strong implication of the diencephalon and cerebral cortex.
通过动物实验和临床试验，我们可以认为针刺内关（EH-6）对某些植物性功能的控制是有效的。我们试图通过简单的定量测量方法来确定这些假设的实际作用范围，如检测心率、收缩压和舒张压以及交感神经电反应。实验在29名健康志愿者身上进行。记录这些参数的基础值，以及在进行传统的内关针刺、非穴位针刺、仰卧15分钟、针刺曲泽（EH-3）以及在手腕内关水平对正中神经进行双极电刺激后的数值。设计这些条件是为了评估非特异性针刺、静息状态以及直接正中神经刺激对内关针刺效果的影响。我们得出结论，内关针刺强烈抑制交感神经张力，使心率、收缩压降低，交感神经电反应幅度显著减小；电反应的潜伏期也延长。还观察到对血压和心率有一些微弱影响，这是针刺和正中神经刺激的非特异性作用。根据先前的解剖学数据，我们推测这种作用水平是超节段性的，间脑和大脑皮层有强烈参与。
