title: [Comparison of cutaneous temperature at 12 Jing-well points regions of bilateral yin- and yang-meridians in healthy volunteers].
abstract: 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 differences were found between the left yin-meridians and right yin-meridians in skin temperature (P > 0.05).
  
  
  CONCLUSIONS
  The average skin temperature values of the Jing-well points are evidently higher at the 6 yin-meridians than at the 6 yang-meridians, obviously higher on the upper limbs than on the lower limbs, and apparently higher on the right meridians than on the left meridians in healthy volunteers.
