OBJECTIVE: To observe the changes of volt-ampere characteristics of Yuan-Primary acupoints in women before, during and after menstruation, and to find out the relationships between Qi-blood in human body and volt-ampere characteristics of acupoints, so as to develop a new method for quantitative analysis on changes of Qi-blood. METHODS: A high-sensitive detection system of volt-ampere characteristics of acupoint was applied to detecting the volt-ampere characteristics of Taiyuan (LU 9), Daling (PC 7) and Shenmen (HT 7) in healthy women before, during and after menstruation. RESULTS: The resistances on LU 9, PC 7 and HT 7 with some certain scan currents were quite different among the women before, during and after menstruation. For such changes, PC 7 was of the most obvious change, LU 9 was of the less and HT 7 was of the least. The total ratio of the scanning spots with significantly increasing changes of resistances on these three acupoints along with the menstrual process was 70.6%. CONCLUSION: The volt-ampere characteristics of acupoints vary with the menstrual process, which is of the acupoint specificity. The resistances on the acupoints increase with the menstrual process, and such results may be due to the blood loss during menstruation. The volt-ampere characteristics can be used as a quantitative index to study on the change of Qi and blood.

Objective:To observe volt-ampere characteristic of Acupoint Neiguan (PC 6) on patients with hyper-thyroidism for probing into the actions of acupoints and change of qi and blood of human body as well as the relationship between the action of acupoint and the metabolism of energy.

Objective:To investigate the variations in infrared radiation at Taichong(LR3),Taixi(KI3),and control points before and after menstruation and to examine the infrared radiation patterns associated with Yuan-primordial points of Zang-Fu organs during the physiological menstrual cycle. Methods:Using a point infrared radiation spectrum detection system,we detected the infrared radiation spectra of Taichong(LR3),Taixi(KI3),and the control points located 1 cm away from the two points,in a range of 1.50-18.00 μm wavelengths during the premenstrual,menstrual,and postmenstrual phases in 32 healthy adult women.Subsequently,data mining and analysis were conducted. Results:Before,during,and after menstruation,the infrared spectral shapes of bilateral Taichong(LR3),Taixi(KI3),and their control points were generally consistent,with characteristic infrared spectral wavelengths located at 11.25 μm.Prior to menstruation,the total intensity of infrared radiation at the right Taixi(KI3)was significantly lower than that at the control point(P<0.05),and that at the left Taichong(LR3)was significantly lower than that at the control point(P<0.01).During and after menstruation,the total infrared radiation intensity at both Taixi(KI3)was significantly lower than that of the control point(P<0.05).The wavelength points exhibiting significant differences in the infrared radiation intensity between points and control points were concentrated at the primary peak of 7.50-14.25 μm and the secondary peak of 15.00-17.25 μm. Conclusion:During different menstrual phases,the infrared radiation spectra of Taichong(LR3)and Taixi(KI3)exhibited distinct point specificity,mainly evident in the infrared radiation intensity and wavelength.

OBJECTIVE: To observe the effect of infrared laser stimulation on Neiguan (PC 6) for bradycardia of rabbits induced by injection of pituitrin. METHODS: 10.6 microm CO(2) infrared laser, 650 nm semiconductor red laser and the compound laser of their aggregation were sent out by a compound laser sanatory instrument to stimulate Neiguan (PC 6) respectively for the purpose of analyzing the differences of the effects exerted by infrared laser and red laser as well as the changes of the effects after their aggregation. RESULTS: After 30 min and 40 min of the injection of pituitrin, the heart rate showed no significant difference between 10.6 microm CO(2) infrared laser group and the normal control group (P>0.05). However, the heart rate showed significant difference between the 650 nm semiconductor red laser group and the normal control group (P<0.05). After 30 min of the injection of pituitrin, the heart rate of the compound laser group were significantly different to that of the untreated group (P<0.05), and it was not significantly different to that of the normal control group (P>0.05). However, the heart rate of non-acupoint stimulated by the compound laser group showed no significant difference to that of the untreated group (P>0.05), and it was significantly different to that of the normal control group (P<0.05). CONCLUSION: Stimulation on Neiguan with 10.6 microm CO(2) infrared laser can evidently improve the bradycardia induced by injection of pituitrin, while the 650 nm semiconductor red laser has no such function, but they have coordinating effect. The thermal effect produced by CO(2) infrared laser stimulating acupoint is probably beneficial for semiconductor laser penetrating skin as well as the biochemical reactions it carries. The improvement of heart rate produced by the laser stimulation on Neiguan (PC 6) has relative specificity.

We have analysed the significance of acupoint resistance and some probable problems in its measurement according to biophysics theories and we believe that the skin resistance plays an important role in acupoint resistance. The Volt-ampere curve should be used to describe acupoint resistance, and only when the measurements are under the same condition should the results be compared, because acupoint resistance is nonlinear. The acupoint resistance could be detected only in vivo. In this paper is presented a simple and easy method with which we can connect acupoint into electric circle. Also reported here is how to control the circumstance condition while measurements are taken.

BACKGROUND: Infrared spectrum technology has potential and important value of application in diagnosing disease and analyzing pathology, as well as providing references for proper treatment. OBJECTIVE: To analyze the distinctive pathological information in the spectrums of infrared radiation at Neiguan (PC 6) acupoint of patients with coronary atherosclerotic heart disease (CAHD). DESIGN: Case-control study.SETFING: Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine. PARTICIPANTS: The study was conducted from April 2003 to April 2005 in patients with CAHD from Out-Patient Clinic in Longhua Hospital (21 males and 29 females, averagely 58.1 years). Forty-seven healthy volunteers were all from advertisement (25 males and 22 females, averagely 50.6 years). All the subjects were voluntary. METHODS: PHE201, a high-sensitive infrared spectrum detective device (Shanghai Institute of Technical Physics of Chinese Academy of Sciences, China) was applied to detect the spectrums of infrared radiation at Neiguan in 50 patients with CAHD and 47 healthy adults were selected as control for comparison. The scanning range was from 1.5μ m to 16μ m,73 detected wavelength spots were scanned at Neiguan of all the subjects, and the scanning spacing was 0.2μ m. MAIN OUTCOME MEASURES: Intensity of infrared radiation at Neiguan between CAHD patients and normal controls at different wavelengths. RESULTS: The intensities of infrared radiation of CAHD patients were significantly different from that of the healthy volunteers at 32 spots of the right Neiguan as well as at 23 spots of the left Neiguan among the 73 detected wavelength spots(P < 0.05-0.001). At 2-2.5μ m wavelength spots that were related to the energy metabolism, the intensities of infrared radiation of CAHD patients were significantly lower than the healthy volunteers (P < 0.05-0.005). Concerning the difference in intensities of infrared radiation between the left and the right Neiguan, the CAHD patients had more wavelength spots than healthy volunteers did (P < 0.001). CONCLUSION: ①Distinctive pathological information exists in the infrared spectrums at Neiguan in CAHD patients. ②CAHD patients have hypo-activities of energy metabolism and hypo-function ofqi and blood in the area of Neiguan.

Cancer-related fatigue (CRF) is a common symptom which associated with cancer itself or cancer treatments. CRF will not only interrupt the patient's treatment, but also affect the patient's quality of life seriously. To date, the pathogenesis of CRF is still unclear, and recognized effective treatment is lacking. It is the precondition of establishing standardized animal models for CRF to find effective treatments. This paper summarizes the animal model of CRF in order to find suitable methods, and distinguish the effects of different interventions.

In this experiment the data of the infrared radiation spectrum of acupoints in human body were obtained through an ingenious device. In thirty-one healthy volunteer subjects and thirty-one patients suffering from coronary heart disease, we detected the infrared radiation spectra from some acupoints and compared them with those of the healthy subjects. The curves of patients showed more differences. After analyzing the data, we noted statistically significant differences in some fields between the healthy subjects and the patients. And after reducing the data, we observed significant differences in larger fields. So utilization of reduced data from patients for analysis is our choice.
