To explore the relationship between the theory of constitution in terms of Chinese medicine and clinical efficacy of acupuncture treatment via analyzling the characteristics of during acupuncture stimulation of Zusanli (ST 36) in healthy volunteers with different constitutions.
In the present study, a total of 527 healthy undergraduate student volunteers (267 girls and 260 boys) were recruited. They received questionnaire first about their constitutions in accordance with Professor WANG Qi's in terms of Chinese medicine. Then, the subjects were asked to take a supine position on a check-bed, a qualified acupuncturist held a sterilized fifiform needle to rapidly insert it into ST 36 and manipulated the acupuncture needle with uniform reinforcing-reducing technique at a frequency of about 60-90 times/min and an amplitude of 0.3-0.5 cm. The status of was assessed by using visual analogue scale (VAS).
Needling sensations mainly involve soreness, numbness, heaviness, distension, dull pain and propagated sensations along meridian (PSC). During acupuncture stimulation, most subjects experienced distension sensation, accounting for 90.3%, followed by soreness, accounting for 45.9%. Except for PSC reaction, the rest 5 needling sensations had no statistical difference in their occurrence rates in those subjects with different constitutions (>0.05). The PSC appeared a higher incidence in harmony(balanced) constitution subjects than in - deficiency, -deficiency, blood-stagnation and -stagnation constitution subjects (<0.05). The intensity of soreness was obviously stronger in the balanced constitution subjects than in -deficiency, -deficiency, -deficiency, phlegm-damp, damp-heat and -stagnation constitution subjects (<0.05), while the intensity of distension sensation was apparently stronger in the balanced constitution subjects than in simpleyang-deficiency subjects (<0.05).
Except for PSC, the sensations of soreness, numbness, heaviness, distension and dull pain induced by acupuncture stimulation of ST 36 are comparable in the occurrence rates in healthy volunteer subjectswith different (9 types of) constitutions in terms of Chinese medicine, whereas the intensity of soreness may be the important factor for acupuncture induced pain relief. A certain correlation between the constitution and acupuncture effectiveness exists, suggesting that acupuncture treatment should vary from patient to patientin clinical practice.
通过分析不同体质健康志愿者针刺足三里（ST 36）时的针感特点，探讨中医体质学说与针刺临床疗效的关系。
本研究共招募527名健康大学生志愿者（女生267名，男生260名）。首先按照王琦教授的中医体质分类方法对其体质进行问卷调查。然后，受试者仰卧于检查床上，由合格的针灸师持消毒后的毫针快速刺入ST 36，采用提插补泻手法均匀捻转，频率约为60 - 90次/分钟，幅度为0.3 - 0.5厘米。采用视觉模拟评分法（VAS）评估针感情况。
针感主要包括酸、麻、重、胀、隐痛和循经感传（PSC）。针刺过程中，多数受试者出现胀感，占90.3%，其次为酸感，占45.9%。除PSC反应外，其余5种针感在不同体质受试者中的发生率无统计学差异（>0.05）。平和质受试者中PSC的发生率高于阳虚质、阴虚质、血瘀质和痰湿质受试者（<0.05）。平和质受试者的酸感强度明显强于阳虚质、阴虚质、气虚质、痰湿质、湿热质和血瘀质受试者（<0.05），而胀感强度在平和质受试者中明显强于单纯阳虚质受试者（<0.05）。
除PSC外，针刺ST 36所诱发的酸、麻、重、胀、隐痛等针感在9种不同中医体质健康志愿者中的发生率相当，而酸感强度可能是针刺镇痛的重要因素。体质与针刺疗效之间存在一定相关性，提示临床针刺治疗应因人而异。
