Visual analysis of research hotspots and frontiers on randomized controlled trials of acupuncture and moxibustion in the past 10 years / 中国针灸

Retrieved the literature on randomized controlled trials (RCT) of acupuncture and moxibustion from 2011 to 2020 in the Web of Science (WOS) database, and explored research hotspots and frontiers in the field of acupuncture and moxibustion by visually analyze to countries, institutions, authors, keywords, cited literature, etc. using CiteSpace V5.6.R2. A total of 1147 articles were included. China has the largest number of publications, and the top 3 publications are Beijing University of Chinese Medicine, Capital Medical University and Kyung Hee University. The hot research interventions in acupuncture and moxibustion include acupuncture, electroacupuncture, and bee acupuncture. The hot research topics include nerve regeneration, spasms, nausea, pain, obesity, cancer, etc. The research frontiers include acupuncture analgesia, diversification of acupuncture and its clinical effects, brain effects of acupuncture and acupuncture clinical mechanisms. It is believed that the cooperation between countries and institutions should be strengthened in the future, and deeper research should be carried out on the research content that is both hot spot and frontier.

Research status and prospects on adenosine receptor mechanism of acupuncture for myocardial ischemia / 中国针灸

The relationship between adenosine receptor (AdoR) and myocardial ischemia (MI), effect of acupuncture for MI and action mechanism of acupuncture improving MI by regulating AdoR are summarized. The existing researches have preliminarily reflected that the improvement of MI treated with acupuncture may be achieved by influencing the expression of AdoR. However, there are still some limitations, e.g. most of the research regimens are single-acupoint, the research results are not entirely consistent and the interaction of AdoRs are ignored, all these need to be further verified and supplemented.

Effect and Safety of CX-DZ-II Intelligent Electroacupuncture Therapeutic Instrument for Neck Pain Caused by Cervical Spondylos: Study Protocol for A Randomized Controlled Trial / 中国结合医学杂志

BACKGROUND@#Neck pain caused by cervical spondylosis (CS) is a chronic pain condition, with an increasingly high incidence in the general population. Electroacupuncture is a common analgesic modality that has been widely applied in neck pain treatment. However, current electroacupuncture instruments used in the clinic have low intelligence levels and obscure parameter standards. We here designed this study for assessing the effect and safety of a new, intelligent electroacupuncture instrument, the CX-DZ-II, in treating neck pain.@*METHODS@#The present study is a prospective, two-center, randomized, controlled, open-label, non-inferiority trial for CX-DZ-II on treating neck pain caused by CS. Totally 160 eligible patients will be included in this trial and randomly assigned to an experimental group and a control group in a 1:1 ratio. A semi-standard acupoint selection strategy will be employed. In the experimental group, selected acupoints will be stimulated by CX-DZ-II. Electroacupuncture treatment will be accomplished by a pre-existing electroacupuncture instrument in the control group. The duration of treatment will be 2 weeks. The primary outcome is the change of Visual Analog Scale (VAS) score after one course of treatment. The secondary outcomes include the VAS scores after each treatment, the responder rate, drug-usage rate of non-steroidal antipyretic analgesics, the rate of adverse events occurrence, and the performance of instrument.@*DISCUSSION@#This study will evaluate the effect and safety of the CX-DZ-II intelligent electroacupuncture therapeutic instrument in comparison with a pre-existing non-intelligent instrument in the treatment of neck pain caused by CS. The results will hopefully demonstrate a more optimal electroacupuncture instrument for the treatment of neck pain. (Trial registration No. gov NCT03005301).

Mechanism of acupoint selection along meridians to improve adenosine receptor of myocardial ischemia based on acupoint specificity / 中国针灸

OBJECTIVE@#To explore the action mechanism of acupoint selection along meridians to improve adenosine receptor in myocardial ischemia (MI) rats by comparing the effects of acupoint selection along meridians, acupoint selection at other meridians and non-acupoint on expression of adenosine receptor.@*METHODS@#A total of 120 SD rats were randomly divided into a blank group, a sham operation group, a model group, an acupoint-selection-along-meridians (ASAM) group, an acupoint-selection-at-other-meridians (ASAOM) group and a non-acupoint group, 20 rats in each group. The model of MI was not made in the blank group; the left anterior descending coronary artery was not ligated after thoracotomy in the sham operation group; the model of MI was made but acupuncture was not given in the model group. After the model of MI was made, electroacupuncture (EA) was applied at "Neiguan" (PC 6) in the ASAM group, at "Hegu" (LI 4) in the ASAOM group, and at the area between the third and fourth metatarsal bone in the non-acupoint group. EA was given 20 min per treatment, once a day for 5 days. After treatment, the TTC staining was used to detect myocardial infarction, the Tunel method was used to detect cardiomyocyte apoptosis, and the immunohistochemistry was used to detect the expression of adenosine receptors A1, A2a and A2b.@*RESULTS@#Compared with the blank group and the sham operation group, the percentage of myocardial infarction and apoptotic rate of myocardial cells in the model group were increased significantly (<0.01). After EA treatment, compared with the model group, the percentage of myocardial infarction and apoptotic rate of myocardial cells in the ASAM group were decreased significantly (<0.01), and the expression levels of adenosine receptors A1, A2a and A2b were increased significantly (<0.01). The percentage of myocardial infarction and apoptotic rate of myocardial cells in the ASAM group were significantly lower than those in the ASAOM group and the non-acupoint group (<0.01), and the expression levels of adenosine receptors A1, A2a and A2b in the ASAM group were significantly higher than those in the ASAOM group and non-acupoint group (<0.01).@*CONCLUSION@#Compared with acupoint selection at other meridians or non-acupoints, acupoint selection along meridians can effectively regulate the expression of adenosine receptors A1, A2a and A2b, improve the condition of myocardial infarction, inhibit myocardial cell apoptosis, and consequently protect ischemic myocardium.
