Comparison of the effects of the intervention with electric thermal bian stone and air suction cup on blood perfusion at Meridian points
Chinese acupuncture & moxibustion, 2018Co-Authors: Peng-na Zhao, Guangjun Wang, Yan-ping Wang, Fei-fei Gu, Chao-zheng Li, Weibo ZhangAbstract:OBJECTIVE: To observe the impacts of the intervention with electric thermal bian stone and air suction cup on blood perfusion (BP) at Meridian points and explore the approach of accurate measurement and regulation of Meridian qi and blood balance in "precise acupuncture". METHODS: The laser Doppler line scanner (LDLS) was used to measure BP at bilateral yuan-primary points at the Pericardium Meridian, the triple energizer Meridian, the gallbladder Meridian and the liver Meridian (small cycle of jueyin to shaoyang Meridians) at 31 healthy receptors. The bias ratio of blood perfusion (BPBR) deviated to the reference value was calculated. The electric thermal bian stone and air suction cup were used in the intervention at the he-sea points of the affected Meridians in which BPBR was relatively higher at the yuan-primary points. The electric thermal bian stone therapy was used when BPBR was less than -30% and the air suction cupping therapy was used when BPBR was higher than 30%. BP was measured twice before intervention and it was measured separately at the moment after intervention and in 20 min after intervention. The means of BP before and after intervention and the change ratio of blood perfusion (BPCR) before intervention, at the moment after intervention and 20 min after intervention were calculated. RESULTS: 1. After the intervention of electric thermal bian stone, BP mean was increased from (103.51±41.21) PU to (121.97±56.22) PU (P 0.05), but the change ratio was highly remained. 2. After intervention with air suction cup, BP mean was reduced from (194.83±81.14) PU to (173.88±88.26) PU. Before intervention, at the moment after intervention and 20 min after intervention, separately, BPCR were (7.62±30.49)%, (-12.12±18.20)% and (-14.35±21.25)%. BPCR at the moment after intervention and in 20 min after intervention were significantly different from that before intervention (both P

Preliminary Observation on Imbalance Degree of Blood Perfusion on the Twelve Yuan-source Points in Healthy Subjects
Acupuncture Research, 2017Co-Authors: Peng-na Zhao, Guangjun Wang, Yan-ping Wang, Fei-fei Gu, Chao-zheng Li, Weibo ZhangAbstract:OBJECTIVE: To lay a foundation for Meridian diagnosis by measuring the blood perfusion (BP) on yuan-source points of twelve Meridians and calculating the normal range of imbalance degree (IBD) of left and right Meridian (IBD-LRM), IBD of exterior-interior Meridian (IBD-EIM) and IBD of hand-foot of the same name Meridians (IBD-HFM) in healthy subjects. METHODS: BP at yuan-source points of twelve Meridians was measured on 31 healthy volunteers by a Laser Doppler Line Scanner (LDLS). BP distribution and IBD-LRM, IBD-EIM, IBD-HFM were calculated. RESULTS: (1) Of the twelve Meridians, BP was almost equal between the left and right of the same Meridian. The mean value of IBD-LRM was (0.8±7.0)%. The absolute value of IBD-LRM ranged from (13.2±12.0)% to (22.9±15.6)%, with the mean value of (16.2±4.1)%, the IBD of gallbladder Meridian of foot-shaoyang was the highest. (2) Of the six pairs of exterior-interior Meridians, five pairs manifested as the interior (yin) Meridians being larger than the exterior (yang) Meridians in BP. The mean value of IBD-EIM was (-11.4±10.4)%. The absolute value of IBD-EIM ranged from (16.6±12.1)% to (36.6±15.6)%,with the mean value of (25.2±8.0)%, the IBD between Pericardium Meridian of hand-jueyin and triple energizer Meridian of hand-shaoyang was the highest. (3)All of the hand-foot of the same name Meridians were found hand Meridians being larger than foot in BP. The mean value of IBD-HFM was (38.8±18.2)%.The absolute value of IBD-HFM ranged from (34.4±20.9)% to (59.6±12.0)%, with the mean value of (43.8±13.3)%, and IBD between heart Meridian of hand-shaoyin and kidney Meridian of foot-shaoyin was the highest. (4) The order of IBD absolute value in BP was the same as transcutaneous CO2 emission (TCE) measured before, and their IBD-LRM absolute values were close to each other. However, the absolute values of IBD-EIM and IBD-HFM existed some differences. CONCLUSIONS: The IBD-LRM of the twelve yuan-source points in BP of healthy subjects is small and in a balance state, but IBD-EIM and IBD-HFM are relatively high.

Pilot study of blood perfusion coherence along the Meridian in forearm.
BMC Complementary and Alternative Medicine, 2013Co-Authors: Guangjun Wang, Yuying Tian, Wenting Zhou, Weibo ZhangAbstract:Many studies have explored the relationship between skin microcirculation and Meridian activation. However, few studies have examined blood perfusion coherence along the Meridians, and other studies have suggested that the skin vasodilator response relates to age. This study investigated blood perfusion coherence characteristics along the Meridian of the forearm in healthy volunteers. A total of 15 young subjects (25.53 ± 2.20) and 15 middle-aged subjects (50.07 ± 3.37) were recruited for this study. Before experiments, each subject was placed in a temperature-controlled room for 60 min. Skin blood perfusion from five points was recorded simultaneously using a full-field laser perfusion imager before and after inflatable occlusion. The five points comprised three points located on the Pericardium Meridian, and two points from different locations. Coherence analysis between these points was performed at different frequency intervals from 0.0095 to 2 Hz. In young subjects, the coherence value was unchanged before and after occlusion, and there was no significant difference in coherence value between Meridian-Meridian points (M-M) and Meridian-paraMeridian points (M-P). In middle-aged subjects, the coherence value increased significantly in both M-M and M-P at frequency intervals of 0.14-0.4 Hz, 0.4-1.6 Hz, and 1.6-2 Hz. However, there was no significant difference in coherence values between M-M and M-P. Inflatable occlusion can increase middle-aged subjects’ blood perfusion coherence value of the forearm. However, there is no specificity in Meridian location.

the distribution of transcutaneous co2 emission and correlation with the points along the Pericardium Meridian
Journal of Acupuncture and Meridian Studies, 2009Co-Authors: Weibo Zhang, Yuying Tian, Ruiming XuAbstract:Abstract This study aimed to understand energy metabolism distribution along the Pericardium Meridian and verify the correlation between the body surface (points), and classic Meridian theory. A highly sensitive CO 2 instrument was used to measure the transcutaneous CO 2 emission at 13 points along the Pericardium Meridian line (12 points on the line and one point beyond the line) and 13 control points beside them. Results showed that the distribution of transcutaneous CO 2 emission is highly related to the position on the body. Transcutaneous CO 2 emission is significantly higher at P7 and P3, than the control points beside them. The points along the Meridian and the points beside them were clustered with relative distance by SAS statistics software. Two distance matrixes were then obtained. The correlation coefficients between the points along the line and between the control points were calculated. The results showed that the 13 th point beyond the line was far from the 12 points on the line (distance, 0.24), while acupoints on the line clustered earlier when compared with the non-acupoints. The average correlation coefficients among the acu-points was 0.65 which was significantly higher than 0.56, among the non-acupoints. No such characteristics were found among the control points. It was concluded that there is a strong correlativity of energy metabolism activity between the body surfaces along the Meridian, and an even stronger correlativity between the acupoints on the Meridian.

Influence of mechanical pressure on the change of acupuncture-induced transcutaneous CO2 emission
Chinese acupuncture & moxibustion, 2009Co-Authors: Rui-hong Wang, Guangjun Wang, Yuying Tian, Tao Huang, Yi-hui Xu, Yu-qin Zhang, Weibo ZhangAbstract:Objective To investigate conduction of acupuncture effect and the influence of mechanical pressing Meridians on it. Methods In twenty healthy volunteers (8 males and 12 females,aged 29 years on average),by using a Frewil Q.F. apparatus,transcutaneous CO2 emission (TCE) was measured before,during and after acupunc-ture at Neiguan (PC 6),respectively. The locations being measured were Quze (PC 3) and four points including two non-acupoints along the Pricardium Meridian (Point A and B) and two non-acupoints apart from the Pericardium Meridian (Point C and D). Point A was located at the lower one fourth of the line connecting Tianquan (PC 2) and Quze (PC 3),and Point B located at the middle of the line connecting Ximen (PC 4) and Quze (PC 3). Point C was located 2 cm lateral on the ulnar side to Point A,and Point D located 2 cm lateral on the ulnar side to Point B. The above results were compared with those obtained after mechanical pressure of 1 kg (area 1 cm×2 cm) applied on Ximen (PC 4) and Daling (PC 7),respectively,to observe their effect on TCE. Results During and after acupuncture at Neiguan (PC 6) without mechanical pressure,TCE at Quze (PC 3),point A and B increased significantly(P0.05),but not at point C and D (P0.05). While applying mechanical pressure at Ximen (PC 4),no significant increase was found on the three points during and after acupuncture. When applying pressure at Daling (PC 7),significant increases of TCE were also found at Quze (PC 3) and point A during acupuncture (P0.05),and a significant increase of TCE was found at point B after acupuncture with pressure keeping (P0.05). Conclusion Acu-puncture can enhance energy metabolism along Meridians,and this effect can be blocked by mechanical pressure.

variations in energy metabolism along the Pericardium Meridian and its relationship with visceral function adjustments during electroacupuncture
BMC Complementary and Alternative Medicine, 2014Co-Authors: Shuxia Zheng, Jinsen Xu, Yaqin DongAbstract:Electroacupuncture (EA) is a traditional Chinese medicine treatment guided by Meridian theory. As it gradually gains more worldwide acceptance, a clarification of its mechanisms is extremely urgent. We observed variations in transcutaneous oxygen pressure/carbon dioxide pressure ( tcp O2/ tcp CO2) and microcirculation blood perfusion units (BPU) along the Pericardium Meridian, and cardiac function during EA at Neiguan (PC6) to explore variations in energy metabolism and its relationship with visceral function adjustments during EA. Twenty-two healthy volunteers participated in this study. Three channel laser Doppler flowmetry and tcp O2/ tcp CO2 detection systems were used to detect tcp O2/ tcp CO2 and microcirculation BPU along the Pericardium Meridian. A hemodynamic monitor was used to detect cardiac function. In the normal state, the microcirculatory BPU along the Pericardium Meridian were significantly higher than that of their bilateral corresponding control points (p < 0.05). During EA at PC6, the values of the microcirculatory BPU along the Pericardium Meridian did not vary, and few increased. In the normal state, the values of tcp O2 along the Pericardium Meridian were significantly higher than those of their bilateral corresponding control points (p < 0.05). In addition, the values of tcp CO2 along the Pericardium Meridian were lower than those of their bilateral corresponding control points. In comparison with the normal state, EA could decrease tcp O2 along the Meridian significantly (p < 0.05) and increase tcp CO2. During EA at PC6 in healthy volunteers treated by artificial acute mild hypoxia, cardiac output and cardiac index (p < 0.05) decreased and systemic vascular resistance increased significantly (p < 0.05). In the normal state, the values of microcirculatory BPU and tcp O2 along the Pericardium Meridian were both higher than those of their bilateral corresponding control points. Energy metabolism was vigorous along the Meridian. During EA, the decrease in oxygen partial pressure along the Pericardium Meridian might be a result of strengthened energy metabolism of associated tissue and increased oxygen consumption. The variations in energy metabolism along the Pericardium Meridian during the course of EA had a close relationship with visceral function adjustments.

The laser Doppler line scanner (LDLS) was used to measure BP at bilateral yuan-primary points at the Pericardium Meridian, the triple energizer Meridian, the gallbladder Meridian and the liver Meridian (small cycle of jueyin to shaoyang Meridians) at 31 healthy receptors. The bias ratio of blood perfusion (BPBR) deviated to the reference value was calculated. The electric thermal bian stone and air suction cup were used in the intervention at the he-sea points of the affected Meridians in which BPBR was relatively higher at the yuan-primary points. The electric thermal bian stone therapy was used when BPBR was less than -30% and the air suction cupping therapy was used when BPBR was higher than 30%. BP was measured twice before intervention and it was measured separately at the moment after intervention and in 20 min after intervention. The means of BP before and after intervention and the change ratio of blood perfusion (BPCR) before intervention, at the moment after intervention and 20 min after intervention were calculated. 1. After the intervention of electric thermal bian stone, BP mean was increased from (103.51±41.21) PU to (121.97±56.22) PU (P<0.05). Before intervention, at the moment after intervention and 20 min after intervention, separately, BRCR were (-0.58±16.18)%, (23.58±48.85) % and (25.62±65.89) %. BPCR at the moment after treatment was increased significantly as compared with that before intervention (P<0.01). The difference was not significant in 20 min after intervention and before intervention (P>0.05), but the change ratio was highly remained. 2. After intervention with air suction cup, BP mean was reduced from (194.83±81.14) PU to (173.88±88.26) PU. Before intervention, at the moment after intervention and 20 min after intervention, separately, BPCR were (7.62±30.49)%, (-12.12±18.20)% and (-14.35±21.25)%. BPCR at the moment after intervention and in 20 min after intervention were significantly different from that before intervention (both P<0.01). . The electric thermal bian stone increases the blood flow at the yuan-primary point when acting on the he-sea point of the same Meridian. The influence of the air suction cup is opposite.

Distribution of low skin impedance points along Meridians over the medial side of forearm
Acupuncture Research, 1993Co-Authors: Hu X, Jinsen Xu, Huang X, Wu BAbstract:: The distribution of low skin impedance points (LSIP) over the medial side of forearm was plotted with a computer system designed for the measurement of skin impedance. Twelve volunteers were under observation. The exploring electrode moved forward in a even velocity from the radial axis of forearm to its ulnar axis and crossed the Lung Meridian, Pericardium Meridian and Heart Meridian in succession. Thus, the measurement covered the whole area of the medial side of forearm. The results showed that the most of 391 LSIPs located right on or within 5 mm bilaterally to the travelling courses of Three Ying Meridians of Hand. It could be found in the area between every two Meridians only in a few cases. Just so, the courses of Three Ying Meridians of Hand were clearly displayed. Under the condition of this experiment, LSIP appeared randomly, but viewing the situation as a whole, the distribution of LSIPs was still following the Meridian courses. The results further demonstrated that the distribution of LSIPs along Meridian courses not caused by the errors in measurement, but really a biological phenomenon, which was objectively existed.

During EA at PC6 in healthy volunteers treated by artificial acute mild hypoxia, cardiac output and cardiac index (p < 0.05) decreased and systemic vascular resistance increased significantly (p < 0.05). In the normal state, the values of microcirculatory BPU and tcp O2 along the Pericardium Meridian were both higher than those of their bilateral corresponding control points. Energy metabolism was vigorous along the Meridian. During EA, the decrease in oxygen partial pressure along the Pericardium Meridian might be a result of strengthened energy metabolism of associated tissue and increased oxygen consumption. The variations in energy metabolism along the Pericardium Meridian during the course of EA had a close relationship with visceral function adjustments.

Variations in energy metabolism along the Pericardium Meridian and its relationship with visceral function adjustments during electroacupuncture
BMC Complementary and Alternative Medicine, 2014Co-Authors: Shuxia Zheng, Jinsen Xu, Yaqin DongAbstract:Electroacupuncture (EA) is a traditional Chinese medicine treatment guided by Meridian theory. As it gradually gains more worldwide acceptance, a clarification of its mechanisms is extremely urgent. We observed variations in transcutaneous oxygen pressure/carbon dioxide pressure ( tcp O2/ tcp CO2) and microcirculation blood perfusion units (BPU) along the Pericardium Meridian, and cardiac function during EA at Neiguan (PC6) to explore variations in energy metabolism and its relationship with visceral function adjustments during EA. Twenty-two healthy volunteers participated in this study. Three channel laser Doppler flowmetry and tcp O2/ tcp CO2 detection systems were used to detect tcp O2/ tcp CO2 and microcirculation BPU along the Pericardium Meridian. A hemodynamic monitor was used to detect cardiac function. In the normal state, the microcirculatory BPU along the Pericardium Meridian were significantly higher than that of their bilateral corresponding control points (p
