Interpretation of acupoint location in traditional Chinese medicine teaching: Implications for acupuncture in research and clinical practice

The effect of acupressure on constipation symptoms and quality of life among older people: a mixed-methods study

PURPOSE

This study aims to evaluate the effect of acupressure on constipation symptoms and quality of life in older people.

METHODS

The study was a double-blind, randomized, sham-controlled, qualitative and quantitative mixed-method study. Individuals in the acupressure group received acupressure for 21 min per day for a total of 12 sessions. The other group received sham acupressure for the same duration. Constipation Assessment Scale (CAS), Constipation Quality of Life Scale (PAC-QOL), Visual Analogue Scale (VAS) and individual follow-up form were used to evaluate quantitative data, and semi-structured interview form was used to evaluate qualitative data.

RESULTS

A total of 81 participants were randomized to acupressure (n = 41, mean age: 70.56 ± 4.76, 70.7% female) or sham acupressure (n = 40, mean age: 71.17 ± 5.19, 67.5% female). Repeated measurements of the participants showed that CAS scores differed significantly between acupressure applications (p < 0.001). There were also statistically significant differences between the two groups in PAC-QOL and VAS after the application, number of defecations and laxative use (p < 0.001). Compared to the placebo group, the acupressure group had significantly lower mean post-test scores in all constipation rating scales. Qualitative findings from the study also support the quantitative findings.

CONCLUSION

For older people seeking evidence-based alternative therapy, acupressure may be a solution to reduce the constipation symptoms. Future studies with larger sample sizes are needed to confirm our study findings.

Accuracy analysis of traditional acupoint location and the coincidence of cutaneous arterial perforators and acupoints

Several reports have shown a coincidence relationship between perforators and acupoints. However, there have been few previous reports of objective experimental methods to verify the reliability of the accuracy of acupoint location (APL) with nearby perforators. This research aimed to determine the internal agreement of the APL of five acupuncturists and to analyze the coincidence rate of acupoints with nearby perforators. Three two healthy volunteers were recruited with the inclusion and exclusion criteria. Three TCM clinical physicians determined acupoints in areas of the lower limb of participants. Two microsurgeons sketched corresponding regions based on the most common skin flap operation sites, located bone markers, and drew the skin flap axis. Doppler ultrasound was used to mark the perforator point and the distances measured for both points. There is no significant difference in the distance between the acupoints and perforators localization in different groups, and there are significant differences between the angle formed by acupoints and penetrators in all groups. All the points located by the traditional Chinese medicine (TCM) therapists are distributed around the dot. The distance between the coordinate point (A-B) of Wēnliū (LI7) localization is the largest, reaching 16.6 mm. The accuracy of the acupoint location of each physician is limited by the clinical experience of physicians, and the difference among them is significant. There is a certain correspondence between the location of acupoints and perforators, which needs further studies to confirm.

West meets east: Taking a stab at acupuncture point names

Acupuncture point names written in Chinese Han characters often provide clinically useful information in both their literal and figurative meanings about location and therapeutic use. The World Health Organization (WHO) standard acupuncture nomenclature includes these names in Han characters in an unusual array that includes both "original" forms and, in parentheses, simplified forms. Construction of a multilingual table of acupuncture point names during development of a database revealed that the assumption that the "original" form in the WHO nomenclature was the traditional Chinese character was frequently false. The Han character forms in the pdf of the 2009 reprint of WHO Standard Acupuncture Point Locations were carefully compared with Han characters used in traditional and simplified Chinese, Japanese and Korean writing systems. This work utilized three online tools: UnicodePlus, Unihan Database Lookup, and Wiktionary. Only 48% of the "original" character forms were traditional Chinese characters. The Unicode number was correct in 99%, but in most cases the East Asian font used was not a traditional Chinese one. The issue about Han character forms was also found in all earlier versions of the WHO standard acupuncture nomenclature. Other detected problems included the use of wrong characters for an "original" character form in one name and for a simplified character form in another name. The WHO standard acupuncture nomenclature should be revised with a focus on accuracy in the usage of Han characters.

An introduction to traditional Chinese medicine, including acupuncture

As an independent medical system, the scientific value behind traditional Chinese medicine (TCM) is gaining appreciation because of growing evidence about mechanisms and efficacy. The aim of this special issue is to introduce this ancient medicine to readers through the compiled research papers focusing on TCM. The papers in this issue cover many research fields such as TCM theory, traditional Chinese prescription, syndrome biomarkers, and acupuncture. In particular for acupuncture, the focus on the history of acupuncture, the importance of precise acupoint positioning, the effect of Fu's subcutaneous needling among patients with shoulder pain, and the effect of electroacupuncture on senile plaque and insulin signaling pathway in the olfactory bulb of transgenic mice. By combining, the papers in this issue and TCM papers published elsewhere provide scientific evidence to improve understanding this ancient Oriental form of medicine.

Introduction of human anatomy before modern China: The preface of anatomical education in mainland China

Anatomy is an early researched discipline of natural science. Ancient civilizations (e.g., Greece, Egypt, Mesopotamia, and China) made significant contributions to our current understanding of medicine, including human anatomy. However, in modern China (from 1912 to the present), some contemporary scholars prefer to overlook the fact that anatomy was studied before modern China. Therefore, the author chronologically lists typical hallmark events and publications related to human anatomy before modern China, summarizes the influences of anatomy on traditional Chinese medicine, and analyzes the reasons for the slow progression of anatomy before modern China. The purpose is to better understand the history and culture of anatomy before modern China, serving as the first step of anatomical education for medical students in mainland China.
