[Analysis of acupoints selection rules and efficacy evaluation of acupuncture and moxibustion for allergic rhinitis].

OBJECTIVE: To explore the rules of acupoints selection of acupuncture and moxibustion in the treatment of allergic rhinitis (AR) by using data mining technology, as well as to compare the efficacy of different acupoints selection methods. METHODS: Papers about acupuncture and moxibustion for treating AR published from January 2002 to August 2022 was retrieved from Chinese and English databases including CNKI, Wanfang, VIP, SinoMed and PubMed by using keywords of "acupuncture", "moxibustion" and "allergic rhinitis". According to the inclusion and exclusion criteria, the collected literature was screened to establish the AR database. Frequency statistic analysis was conducted for detecting high-frequency acupoints and specific acupoints frequency, and the curative effects of different acupoints selection methods were compared. SPSS26.0 software was used for factor analysis, cluster analysis and QUEST decision tree model identification. RESULTS: A total of 289 papers were included, with 384 acupuncture prescriptions extracted. A total of 99 acupoints were involved with the application frequency of 2 430 times. Among them, the application frequency of Yingxiang (LI20) is the highest (296 times, 12.18%), followed by Yintang (GV24+) and Hegu (LI4), etc. The main invloved meridians are the Bladder Meridian of Foot-Taiyang, the Large Intestine Meridian of Hand-Yangming and the Governor Vessel. The involved specific acupoints with the highest frequency of application is the crossing acupoints. Nine common factors of acupoints combinations units were extracted by factor analysis, and two cluster prescriptions of acupoints combinations correlation were obtained by cluster analysis. Three decision paths of simplified acupoints selection were simulated by the decision tree, with LI20 as the dependent variable. CONCLUSION: In the treatment of AR with acupuncture and moxibustion, the regularities and characteristics of acupoints selection are as follows: 1) often selecting local acupoints and acupoint combinations along meridians, 2) focusing on combination of dispelling pathogenic factors with strengthening vital energy, 3) advocating diversification of acupoint matching methods. The combination of factor analysis, cluster analysis and QUEST decision tree application provides three directions for clinical acupoints selection of AR.

The effect of acupuncture used for cervical spondylosis of vertebral artery type: A protocol for systematic review and meta-analysis.

BACKGROUND: Cervical spondylosis of vertebral artery type is a common clinical disease. With the change of people's lifestyle and the improvement of people who work at desks, its incidence is also increasing, which can seriously affect people's normal life and work. Acupuncture has been gradually accepted and recognized by the public for its green, simple and safe characteristics. In this systematic review, we aimed to evaluate the effect and safety for patients with cervical spondylosis of vertebral artery type to provide evidence for clinical decision making. METHODS: We will search the following 8 databases from their inception to November 2021: Web of Science, the Cochrane Library, PubMed, Embase, Chinese Biomedicine, China National Knowledge Infrastructure, Chinese Scientific Journals Database, and the WanFang Database. All relevant randomized controlled trials (RCTs) that meet the inclusion criteria will be included in our analysis. Literature screening, data extraction and literature quality assessment will be carried out in a step. Data analysis will be performed using RevMan 5.4 software. RESULTS: Based on the results of this study, we will evaluate the safety and effectiveness of acupuncture in the treatment of vertebral artery type cervical spondylosis. CONCLUSION: This study will provide strong evidence-based medical evidence for acupuncture in treating cervical spondylosis of vertebral artery type. PROSPERO REGISTRATION NUMBER: CRD42021293053.

[Analysis on combination regularities of Houxi (SI3) in ancient times of China based on latent structure model].

OBJECTIVE: To explore the feasibility and application value of combination regularities of acupoint Houxi (SI3) in Chinese ancient times based on latent structure model. METHODS: Relevant articles about SI3 for treating various diseases with acupuncture, moxibustion, acupoint application, etc. were mainly searched from book Chinese Medical Classics (5th edition), followed by establishment of a Database of Houxi Acupoint Recipes. The Lantern 5.0 software was used to construct and analyze the latent structure model of high-frequently-used acupoints. RESULTS: A total of 46 high frequently-used acupoints contained in 240 articles of 26 medical books were collected. The top 7 acupoints are Shenmai (BL62), Hegu (LI4), Qiangu (SI2), Fengchi (GB20), Jianshi (PC5), Wangu (SI4) and Quchi (LI11) in sequence. After modeling the 46 high-frequently used adjunct acupoints, 12 latent variables (Y0-Y11) and 24 latent classes were obtained by setting the cumulative coverage threshold ratio to be 95%. According to the Bayesian information criterion (BIC) measure, the model score was -2 170.68 points. Seven comprehensive clustering models were summarized up according to the latent structure. Compared with the yin meridians, the yang meridians played a more significant role. The multiple combinations of SI3 with specific acupoints provided a reference for clinical practice. The supplementary acupoints mainly distribute in the upper and lower limbs, head, face, neck, etc. and the SI3 acupoint recipes function mainly in dredging and activating meridians and collaterals, clearing away pathologic heat and wind, improving eyesight, and relieving swelling and pain. CONCLUSION: The latent structure model is applicable in analysis of the regularities of SI3 acupoint combination for treating some diseases. Comprehensive clustering is employed to determine the primary acupoint SI3 and adjunct acupoint matching, revealing the common regularity and logical progressive relationship between the primary and secondary points, which may be helpful for teaching, clinical and scientific research.

Efficacy and Safety of Transcutaneous Electrical Acupoint Stimulation (TEAS) for Postoperative Pain in Laparoscopy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

OBJECTIVES: This meta-analysis aimed to assess the efficacy and safety of transcutaneous acupoint electrical stimulation (TEAS) for postoperative pain in laparoscopy. The review has been registered on the "INPLASY" website and the registration number is INPLASY202150101. METHODS: Relevant randomized controlled trials are selected from seven electronic databases (PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure, Chongqing VIP Information, WanFang Data, and Chinese Biomedical Database) from their inception up to November 30, 2020. Twenty-eight studies were included in this meta-analysis, and the statistical analyses and the exploration of heterogeneity sources were conducted by Stata 15.0 software. Besides, the bias assessment of the included studies was evaluated using the Cochrane risk of bias tool. RESULTS: In total, 28 RCTs covering 2787 participants were included. The meta-analysis suggested that TEAS can effectively relieve pain in the short term after laparoscopy, reduce the postoperative consumption of rescue analgesics, improve the quality of life of patients, and shorten the length of hospitalization. And no serious adverse events are related to TEAS. Therefore, TEAS is relatively safe and efficacy for clinical application. The most used acupoints were Hegu (LI14), Neiguan (PC6), and Zusanli (ST36). CONCLUSIONS: TEAS can be recommended as a complementary and alternative therapy for the treatment of postoperative pain after laparoscopy. However, the included RCTs had some methodological limitations. Therefore, larger-size, more rigorous, and higher-quality RCTs are needed in the future to further explore the efficacy and safety of TEAS for postoperative pain after laparoscopy.

The efficacy and safety of transcutaneous electrical acupoint stimulation (TEAS) for postoperative pain in laparoscopy: A protocol for systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: With the promotion of the concept of "minimally invasive" surgery, the advantages of laparoscopic surgery are increasingly manifested. However, the postoperative pain of laparoscopic surgery brings difficulties and challenges to patients' rehabilitation. Transcutaneous electrical acupoint stimulation (TEAS) is a non-invasive treatment, which can exert the dual efficacy of acupuncture and electrical stimulation. The efficacy and safety of TEAS for postoperative pain after laparoscopy based on randomized controlled trials (RCTs) need to further evaluate. METHODS: A comprehensive and systematic literature searching will mainly perform on 7 electronic databases (PubMed, the Cochrane Library, Embase, China National Knowledge Infrastructure, Chongqing VIP Information, WanFang Data, and Chinese Biomedical Database) from their inception up to November 30, 2020. We will also search for ongoing or unpublished studies from other websites (eg, PROSPERO, ClinicalTrials.gov, and Chinese Clinical Trial Registry) and do manual retrieval for potential gray literature. Only the relevant RCTs published in English or Chinese were included. Two independent investigators will independently complete literature selection, assessment of risk bias, and data extraction, the disagreements will be discussed with the third party for final decisions. The primary outcome measures: the pain intensity (eg, VAS) and the consumption of postoperative analgesics. The secondary outcome measures: the postoperative quality of life, the duration of hospitalization, and the incidence of adverse reactions and serious events. Assessment of bias risk will follow the Cochrane risk of bias tool. Data processing will be conducted by Stata 15.0 software. RESULTS: We will evaluate the efficacy and safety of TEAS for postoperative pain after laparoscopy based on RCTs. CONCLUSION: This study can provide more comprehensive and strong evidence of whether TEAS is efficacy and safe for postoperative pain in laparoscopic surgery.
