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(LU11)

Sahngyang(LI1)

Yinbai(SP1)

Lidui(ST45)

Shaochong(HT9)

Shaoze(SI1)

Yongquan(KI1)

Zhiyin(BL67)

Zhongchong(PC9)

Guanchong(SJ1)

Dadun(LR1) and Qiaoyin(GB44) ] at night(19:00-21:00) was detected under a room temperature of(20±2)℃ 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(BL67) was significantly lower than that of Yongquan(KI1

P<0.05).No significant differences were found between Shaoshang(LU11) and Shangyang(LI1)

Yinbai(SP1) and Lidui(ST45)

Shaochong(HT9) and Shaoze(SI1)

Zhongchong(PC9) and Guanchong(SJ1)

and between Dadun(LR1) and Qiaoyin(GB44) 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-meri-dians 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).Conclusion 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.
