[Changes of microcirculation in superficial tissues of acupoint regions of lower leg during menstrual cycle in healthy young girls].

Objective: To observe changes of microcirculation in the superficial regions of acupoints of the three Yin meridians of foot during the menstrual cycle in young college students, so as to provide experimental evidence for explaining the saying of traditional Chinese medicine that acupoints reflect the state of physiological and pathological activities of the internal organs.

Methods: Ninety healthy female volunteer college students were recruited in the present study. The subjects were asked to take a supine position on an examination couch to expose the Yuan-primary acupoints Taixi (KI3), Taibai (SP3) and Taichong (LR3), and Xi-cleft acupoints Shuiquan (KI5), Diji (SP8) and Zhongdu (LR6) which are related to the uterus of the three Yin meridians of foot， the crossing acupoints of the three Yin meridians of foot Sanyinjiao (SP6), non-specific acupoint of the Spleen meridian Xuehai (SP10), non-related meridian acupoint Xuanzhong (GB39) and non-meridian-non-acupoint (being at the same level of GB39, between the Stomach and Gallbladder meridians on the lateral aspect of the lower leg).

[Regularity of body surface resistance at the acupoints of three yin meridians of the foot in reflecting physiological changes of the uterus].

Objective: To investigate the specific regularity of body surface resistance at different acupoints of the meridians associated with the uterus in reflecting menstrual cycle by observing the change in body surface resistance at source points, cleft points, confluent points, and non-specific points of three meridians of the foot in different menstrual cycles in normal female college students, to lay a foundation for the in-depth research on the mechanism of acupoints reflecting the function of , and to provide a reference for the clinical and scientific research on the biophysical characteristics of menstrual cycle-related acupoints in normal female.

Methods: A total of 90 normal female college students were recruited. The source points, cleftpoints, confluent points, and non-specific points of three yin meridians of the foot which were located in the adjacent spinal segments of the uterus were selected, and body surface resistance was monitored for 30 consecutive minutes at the same time-points of menstrual phase, follicular phase, ovulation phase, and luteal phase to observe the change in the resistance of each acupoint during the menstrual cycle.

[Progress of researches on electrical characteristics of meridians and acupoints in recent 10 years].

The electrical characteristics of meridians and acupoints have been being one of the hot topics discussed by scholars, because of many influencing factors and inconsistent research results. In the present article, we collected papers published in Chinese or English in recent 10 years from PubMed, CNKI, and VIP databases by using key words of"acupuncture""meridian""resistance""capacitance""electrodermal"and"impedance". Then, we make an analysis about its development from three aspects, 1) manifestations of electrical properties of acupoints (low dermal resistance under pathological state, imbalance between left and right sides of the synonym acupoints), 2) clinical application of acupoint electrical characteristics for diagnosis of clinical disorders and evaluation of therapeutic effect, and 3) current situations of development of meridian detection instruments based on electrical characteristics (improving stability of instruments，expansion of the detected regions and measuring time, realization of visualization, and operational automation).

[Progress of researches on specificity of acupoints in China in recent 10 years].

After searching for literature about the specificity of acupoints from China National Knowledge Infrastructure (CNKI) database (in Chinese) and MEDLINE (in English), published by Chinese scholars from June 2003 to June 2012, the authors made a systemic analysis on the retrieved papers. It was found that most Chinese scholars took a positive viewpoint about the specificity of acupoints in morphological structure, biophysical characters, pathological reactions, acupuncture stimulation-induced responses in different brain regions and therapeutic effects. However, the research methods and comprehensive analysis of abundant research results need being improved, and the conclusion should be validated extensively.

[Survey on the evaluation indices of acupuncture clinical trials for primary dysmenorrhea in recent 10 years].

Based on the retrieval of literatures at home and abroad from 2000 to 2011, the evaluation indices of acupuncture clinical trials for primary dysmenorrhea (PD) were analyzed. The results indicated that in domestic area the reports were more concerned with the improvement of clinical symptoms and signs while paid less attention on the objective evaluation methodology, on the other hand, the studies abroad generally took many kinds of scales as their evaluation indices and focused on the patients' quality and activity of daily life. The authors suggeste that our clinical research, according to the designed intentions, should combine the general indicators with the specific indicators of diseases to have a more comprehensive evaluation on the effects of acupuncture for PD in clinical practice.

[History and progress of study on electrical properties of acupoints at home and abroad].

Ninety articles on electrical properties of acupoints and 38 closely related articles with the time raged from 1950s' till present were retrieved and studied from Pubmed, CNKI and VIP databases. Conclusions indicate that most of the low-resistance points or high potential points of the skin are in accordance with acupoints. However, not every acupoint shows the property of low-resistance or high potential feature.
