[Comparison of cutaneous temperature at 12 Jing-well points regions of bilateral yin- and yang-meridians in healthy volunteers].
摘要
OBJECTIVE: To observe differences of cutaneous temperature of the 12 Jing-well points regions of the yin-meridians and yang-meridians, and on the upper and lower limbs so as to provide a reference for clinical diagnosis. METHODS: A total of 26 healthy young volunteers (15 men and 11 women, 23 to 31 years in age) participated in the present study. The skin temperature of the 12 Jing-well points [Shaoshang (LU 11), Sahngyang (LI 1), Yinbai (SP 1), Lidui(ST45), Shaochong (HT9), Shaoze (SI 1), Yongquan (KI 1), Zhiyin (BL 67), Zhongchong (PC 9), Guanchong(SJ 1), Dadun (LR 1) and Qiaoyin (GB 44)] at night (19:00-21:00) was detected under a room temperature of (20 +/- 2) degrees C and humidity of 65%-75% by using an infrared thermometer. RESULTS: Comparison between the single Jing-well point of the yin-meridians and that of the yang-meridians showed that only the cutaneous temperature of Zhiyin (BL 67) was significantly lower than that of Yongquan (KI 1, P < 0.05). No significant differences were found between Shaoshang (LU 11) and Shangyang (LI 1), Yinbai (SP 1) and Lidui (ST 45), Shao-chong (HT 9) and Shaoze (SI 1), Zhongchong (PC 9) and Guanchong (SJ 1), and between Dadun (LR 1) and Qiaoyin (GB 44) in the skin temperature (P > 0.05). Comparison between the 6 Jing-well points of the 6 yin-meridians group and those of the 6 yang-meridians group showed that the average skin temperature of the latter was significantly lower than that of the former (P < 0.01). The average skin temperature was significantly lower at the 3 Jing-well points of the 3 yin-meridians of foot than that at the 3 Jing-well points of the 3 yin-meridians of hand (P < 0.01). Such is the case at the 3 Jing-well points of the 3 yang-meridians of foot in comparison with the 3 yang-meridians of hand (P < 0.01). The average skin temperature of the 6 Jing-well points of the right yang-meridians was significantly higher than that of the 6 Jing-well points of the left yang-meridians (P < 0.01). No significant di
