ABSTRACT
Objectives.  De qi is the subjective constellation of sensations perceived by the acupuncturists and patients as described in several literatures, but the absence of quantitative evaluation methods in de qi restricts the use of acupuncture treatment widely in the world. In the present study, we tried to investigate the intrinsic property of de qi is and how evaluate it quantitatively. Methods. 30 healthy adult volunteers were determined to investigate intrinsic changes in the human body after acupuncture with de qi. Results. Acupuncture treatment with de qi apparently increased acupoint blood flow, tissue displacement, and the amplitude of myoelectricity after de qi on acupoints. Furthermore, acupuncture treatment induced fMRI signal increase/decrease in different brain regions although no significant change in electroencephalography. Interpretation. The intrinsic change of the subjects representing the specific response of acupoints and human brain to acupuncture indicated that de qi might be evaluated quantitatively by those above aspects, which facilitated the confirmation in validity and propagation of this treatment modality widely in the world.

Myoelectricity and deep resistance at acupoints following acupuncture before and after de qi. The Viking Quest portable EMG/evoked potential systems were used in this study for analysis of the myoelectricity and deep resistance. The deep resistance before de qi in Hegu acupoint of the healthy subjects was 34.85 ± 12.43, which was increased to 51.98 ± 11.84 uV after de qi (P < 0.01). The similar results were seen for Zusanli acupoint which was 39.38 ± 9.07 uV before de qi and 55.18 ± 6.19 uV after de qi (P < 0.01).  Figure 5 is the representative image of myoelectricity at acupoints following acupuncture before and after de qi ((a1) and (a2) for Hegu; (b1) and (b2) for Zusanli). The amplitudes of myoelectricity after de qi in Hegu and Zusanli were significantly increased than those before de qi.
