The utilization of acupuncture as a therapeutic intervention for the management of postoperative nausea and vomiting has experienced a notable increase in its popularity, and the purpose of this ...analysis is to provide a comprehensive understanding of the level of concern within the academic discipline and the main contributors and their partnership, as well as to identify research focal points and trends.
A comprehensive search was carried out to identify relevant articles on the topic of acupuncture therapy for PONV in the Web of Science and China National Knowledge Internet. The search spanned from January 1, 2011, to June 6, 2023. The annual publications were count to see the degree of scholarly attention devoted to the discipline and how it has changed over time. A statistical analysis of article distribution across various journals was conducted to serve a rough indicator for assessing the quality of articles. And a bibliometric analysis was conducted using the software CiteSpace to visually analyze various aspects of the literature. Analyze authors, institutions and countries to identify the main contributors and their collaborative relationship; and analyze keywords and references to explore research hotspots and trends.
This study examined a comprehensive collection of 819 articles focused on acupuncture therapy for PONV, demonstrating a varying upward trend in the quantity of publications. Notably, the most productive author and institution were identified as Zheng Man and Guangzhou University of Traditional Chinese Medicine, respectively. While China had the highest number of publications, the United States held a greater prominence in this specific field. Collaboration among contributors was found to be weak. High-frequency keywords in the publications included "transcutaneous electrical acupoint stimulation," "electroacupuncture," "pain," and so forth. The literature with the highest citation count pertained to “Stimulation of the wrist acupuncture point PC6 for preventing postoperative nausea and vomiting,” while the article with the highest centrality was “Consensus Guidelines for the Management of Postoperative Nausea and Vomiting.” Several large clusters obtained from the references are also included “postoperative pain,” “transcutaneous electrical acupoint stimulation”. Nothing pertaining to mechanism study was found in the analysis results.
The utilization of acupuncture for the treatment of postoperative nausea and vomiting has been gaining increasing recognition, although there remains room for improvement in the quality of research conducted in this area. Chinese authors and institutions have emerged as significant contributors to this field, while the United States has demonstrated greater proficiency in fostering collaborative efforts. It is imperative to enhance collaboration among these contributors. The current focal points of acupuncture for PONV encompass pain management, electroacupuncture, auricular acupuncture, and transcutaneous electrical acupoint stimulation. Additionally, TEA and enhanced recovery after surgery have been identified as the forefronts of research in this particular domain. In addition, there is still much room for research in the aspect of mechanism and insurance coverage. This study provides an in-depth perspective on acupuncture for PONV, which offers reference material for clinicians with rational choice of therapeutic scheme, educators with hot topics, and researchers with valuable research directions.
•Acupuncture for PONV has gradually attracted attention.•The partnerships between authors and institutions are weak, and global cooperation needs to be strengthened.•We provide research hotspots and frontiers on acupuncture for PONV.
IntroductionLow back pain (LBP) is a major global public health problem and the majority (nearly 90%) of patients with LBP suffer from non-specific LBP (NSLBP). Acupuncture has been widely used for ...relieving pain and is recommended as a first-line treatment in LBP guidelines. However, the guidelines do not recommend a specific acupuncture temporal dosage. A Bayesian model-based network meta-analysis (MBNMA) will be conducted to optimise the dosages of time parameters (session, frequency and duration).Methods and analysisThe following databases will be searched from their inception until 1 July 2023: MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, Web of Science, Cumulative Index to Nursing & Allied Health Literature (CINAHL), alternative health research database (Alt HealthWatch), China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database for Chinese Technical Periodicals, ClinicalTrials.gov, the WHO’s International Clinical Trial and Chinese Clinical Registry. RCTs assessing the effects of acupuncture on chronic NSLBP will be selected. The primary outcome measure will be the improvement in pain intensity at different acupuncture time points. The MBNMA will be performed using R V.4.2.1 with related R packages. Risk of Bias V.2.0 and Confidence in Network Meta-Analysis will be used to assess the evidence quality.Ethics and disseminationEthical approval is not required for literature-based studies. The results will be published in peer-reviewed journals or conferences.PROSPERO registration numberCRD42022336056.
Cancer-related fatigue (CRF) is one of the most commonly reported symptoms impacting cancer survivors. This study evaluated and compared the effectiveness and safety of acupuncture treatments for ...CRF.
We searched PubMed, Embase, Web of Science, Cochrane Library, China Biology Medicine China National Knowledge Infrastructure, China Science and Technology Journal Database, and WanFang Database from inception to November 2022 to identify eligible randomized controlled trials (RCTs) comparing acupuncture treatments with sham interventions, waitlist (WL), or usual care (UC) for CRF treatment. The outcomes included the Cancer Fatigue Scale (CFS) and Pittsburgh Sleep Quality Index (PSQI), and pair-wise and Bayesian network meta-analyses were performed using STATA v17.0.
In total, 34 randomized controlled trials featuring 2632 participants were included. In the network meta-analysis, the primary analysis using CFS illustrated that point application (PA) + UC (standardized mean difference SMD = -1.33, 95% CI = -2.02, -0.63) had the highest probability of improving CFS, followed by manual acupuncture (MA) + PA (SMD = -1.21, 95% CI = -2.05, -0.38) and MA + UC (SMD = -0.80, 95% CI = -1.50, -0.09). Moreover, the adverse events of these interventions were acceptable.
This study demonstrated that acupuncture was effective and safe on CRF treatment. However, further studies are still warranted by incorporating more large-scale and high-quality RCTs.

Chronic Obstructive Pulmonary Disease (COPD) is a globally common chronic respiratory disease with a high morbidity and mortality rate. Acupuncture has been proven effective for COPD. A dose-response ...meta-analysis was conducted to assess the correlation between the acupuncture temporal parameters(session, frequency, and duration) and its effectiveness in patients with stable COPD.
Acupuncture randomized controlled trials on COPD were searched in eight databases from their inception to June 2023. The "doses" were defined as the acupuncture session, frequency, and duration. The outcomes mainly included Forced Expiratory Volume in one-second rate (FEV1%) and Six-minute Walking Distance (6MWD). The assessment of bias risk and literature quality were conducted independently using the Cochrane risk of bias tool and the Standards for reporting interventions in clinical trials of acupuncture. The dose-response relationship was modeled using robust error element regression, and meta-analysis was operated by R 4.3.1 and Stata 15.0. The protocol was registered in PROSPERO with the registration number CRD42023401406.
Out of 1669 records, 17 RCTs with 1165 participants were finally included in the meta-analysis. There was notable heterogeneity among the studies, but sensitivity analysis demonstrated good robustness. The findings revealed a significant improvement in the following outcomes for stable COPD patients in the acupuncture group: FEV1% (MD=3.50, 95%CI: 2.05–4.95), 6MWD (MD=47.39, 95%CI: 29.29–65.50), St. George's respiratory questionnaire (SGRQ; MD=−8.25, 95%CI: −11.38 to −5.12); COPD assessment test (CAT; MD=−2.91, 95%CI: −3.99 to −1.83). The relationship between the acupuncture session, duration, and FEV1%, 6MWD followed a "Λ" curve pattern, while the relationship between acupuncture frequency and FEV1%, 6MWD exhibited logarithmic growth. Firstly, After 12 acupuncture sessions, FEV1% and 6MWD increased by 7.06% (95%CI: 4.56–9.55) and 36.28 m (95%CI: 20.37–52.20), respectively. The peak improvement in FEV1% and 6MWD was observed after 18 acupuncture sessions (MD=7.89, 95% CI: 5.33–10.45) and 45 sessions (MD=125.43, 95% CI: 72.80–178.07) each. Additionally, weekly acupuncture resulted in a 4.14% improvement in FEV1% (95% CI: 2.55–5.72) and a 42.49 m increase in 6MWD (95%CI: 17.16–67.81). Notably, the maximum effects on FEV1% and 6MWD improvement were achieved with different acupuncture frequencies, specifically three times a week (MD=6.00, 95% CI: 5.34–6.66) and once a day(MD=112.41, 95% CI: 77.27–147.56), respectively. Furthermore, after a 28-day duration of acupuncture treatment, FEV1% increased by 4.74% (95% CI: 3.73–5.75) and 6MWD increased by 47.34 m (95%CI: 22.01–72.67). During 60 days of acupuncture treatment, the FEV1% and 6MWD improvement reached their highest levels at 8.76% (95% CI: 7.05–10.47) and 88.06 m (95% CI: 45.96–130.16), respectively.
Acupuncture was effective in improving FEV1%, 6MWD, SGRQ, and CAT in patients with stable COPD. There was a dose-response relationship between the time parameters of acupuncture (session, frequency, and duration) and the efficacy of COPD treatment (FEV1% and 6MWD). The minimal clinically important difference could be achieved after 12 acupuncture sessions. Acupuncture with a medium-frequency (2–3 times per week) over 60 days may result in the greatest improvement in FEV1%, while higher-frequency acupuncture (5–7 times per week) for 2 months may lead to the maximum improvements in 6MWD. It indicated that the optimal acupuncture duration for different indicators remains consistent, while the optimal frequencies may differ. To confirm these results, it is necessary to conduct multicenter, large-scale randomized controlled trials.
Ethical approval is not required for literature-based studies. The results will be published in peer-reviewed journals or conferences.

Deqi
is taken as an indispensable requirement to achieve acupuncture efficacy. This study aimed to explore the central influence of
deqi
on the efficacy of acupuncture for functional dyspepsia (FD). ...70 FD patients were randomized to receive 20 sessions’ acupuncture treatment with (
n
= 35) and without
deqi
(n = 35). In each group, 25 FD patients randomly selected underwent functional magnetic resonance imaging (fMRI) scans before and after treatment. After group re-division according to
deqi
response, changes of amygdala subregions-based resting-state functional connectivity (rsFC) were compared between the acupuncture with and without obvious
deqi
group. The clinical changes of the Nepean Dyspepsia Symptom Index (NDSI) measuring FD symptoms were also used to further assess the correlation with amygdala subregions rsFC in FD patients. The decrease in the NDSI scores (pre-pos) in the obvious
deqi
group was significantly greater than that in the acupuncture without obvious
deqi
group (
p
< 0.05). Compared to the without obvious
deqi
group, the obvious
deqi
group showed significantly decreased the left basolateral amygdala (BLA) rsFC with bilateral insular (INS), putamen and middle/posterior cingulate cortex (MCC/PCC), right pallidum and hippocampus (HIPP) after treatment. The changed NDSI scores(pre-post) of all 41 FD patients was significantly positively correlated with their Fisher’s transformed z value of the left BLA rsFC with left INS (r = 0.376, FDR corrected
p
= 0.015), and rsFC with right HIPP (r = 0.394, FDR corrected
p
= 0.015). The changed NDSI scores(pre-post) of the obvious
deqi
group was significantly negatively correlated with their Fisher’s transformed z value of the right centromedial amygdala (CMA) rsFC with left medial prefrontal cortex (mPFC) (r = −0.463,
p
= 0.035). The results tested the hypothesis that the advantage of
deqi
on efficacy is related to affecting the BLA and CMA rsFC. It suggested that
deqi
might influence the abnormal rsFC within the salience network (SN), and participate in the adaptive modulation of disrupted relationship between the SN and default mode network (DMN).
Different acupoints exhibiting similar therapeutic effects are a common phenomenon in acupuncture clinical practice. However, the mechanism underlying this phenomenon remains unclear. This study ...aimed to investigate the similarities and differences in cerebral activities elicited through stimulation of CV12 and ST36, the two most commonly used acupoints, in the treatment of gastrointestinal diseases, so as to partly explore the mechanism of the different acupoints with similar effects. Thirty-eight eligible functional dyspepsia (FD) patients were randomly assigned into either group A (CV12 group) or group B (ST36 group). Each patient received five acupuncture treatments per week for 4 weeks. The Symptom Index of Dyspepsia (SID), Nepean Dyspepsia Symptom Index (NDSI), and Nepean Dyspepsia Life Quality Index (NDLQI) were used to assess treatment efficacy. Functional MRI (fMRI) scans were performed to detect cerebral activity changes at baseline and at the end of the treatment. The results demonstrated that (1) improvements in NDSI, SID, and NDLQI were found in both group A and group B (
< 0.05). However, there were no significant differences in the improvements of the SID, NDSI, and NDLQI scores between group A and group B (
> 0.05); (2) all FD patients showed significantly increased amplitude of low-frequency fluctuation (ALFF) in the left postcentral gyrus after acupuncture treatment, and the changes of ALFF in the left postcentral gyrus were significantly related to the improvements of SID scores (
= 0.358,
= 0.041); and (3) needling at CV12 significantly decreased the resting-state functional connectivity (rsFC) between the left postcentral gyrus and angular gyrus, caudate, middle frontal gyrus (MFG), and cerebellum, while needling at ST36 significantly increased the rsFC between the left postcentral gyrus with the precuneus, superior frontal gyrus (SFG), and MFG. The results indicated that CV12 and ST36 shared similar therapeutic effects for dyspepsia, with common modulation on the activity of the postcentral gyrus in FD patients. However, the modulatory pattern on the functional connectivity of the postcentral gyrus was different. Namely, stimulation of CV12 primarily involved the postcentral gyrus-reward network, while stimulation of ST36 primarily involved the postcentral gyrus-default mode network circuitry.
Acupuncture is an effective therapy for functional dyspepsia (FD). However, the efficacy of acupuncture in the treatment of FD varies among individuals in clinical practice. This study aimed to ...reveal the brain response patterns in acupuncture higher response/lower response FD patients. Firstly, we performed a within-group comparison of brain function activity before and after acupuncture treatment in 115 FD patients and analyzed the correlation between brain function activity changes and clinical improvements. Secondly, 115 subjects were divided into the acupuncture higher response group or the lower response group based on the median clinical improvement values. The changes in functional brain activity after acupuncture treatment were investigated in these two groups, respectively. Finally, the identified brain regions associated with the clinical improvements were set as regions of interest (ROI), and the ROI-to-voxel functional connectivity comparisons were also performed in both groups, respectively. The results demonstrated that the functional activities of the left cerebellum inferior, right middle temporal gyrus, and right medial prefrontal cortex (mPFC) were increased, and the left Heschl and right middle cingulate cortex were decreased in 115 FD patients after acupuncture treatment. The functional connectivity changes of mPFC were correlated with improving the Nepean Dyspepsia Symptom Index. The significant increase in mPFC functional activity was also found in acupuncture higher response FD patients but not in lower response FD patients. The functional connectivity between the mPFC and default mode network (DMN) was significantly diminished in the higher response group but not in the lower response group. In conclusion, this study suggested that modulating the functional activity of the mPFC and its connectivity to the DMN may be one of the important mechanisms of acupuncture for treating FD with a higher response.

Background
The acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a common respiratory disease among older adults, which imposes a significant burden on individuals and society ...and poses a major challenge to the global public health system due to its high morbidity and mortality. Acupuncture is effective for AECOPD, but its efficacy has been questioned due to the limited methodological quality. Thus, we aim to investigate the efficacy of acupuncture as adjunctive therapy for AECOPD and determine whether the efficacy of acupuncture differs with the type of acupoint combinations.
Methods and analysis
This study proposes a prospective, multicenter randomized controlled trial that will comprise four groups, including two acupuncture treatment groups, one sham acupuncture group, and one basic treatment group. The acupuncture treatment groups will be distinguished by their focus on different patterns of acupoint combination, namely the Xi-cleft and He-sea acupoint combination and the Eight Confluence points acupoint combination, which may vary in clinical efficacy based on traditional acupuncture theories. The study aims to randomize 556 patients in a 1:1:1:1 ratio across the four groups. Each patient in acupuncture group or sham acupuncture group will receive routine drug therapy and 7 sessions of acupuncture treatment over 1 week. Participants in the basic treatment group will only receive routine drug therapy. The trial will be conducted in seven hospitals located in China. The primary outcomes in this trial will include differences in the Breathlessness, Cough, and Sputum Scale (BCSS) before randomization, 7 days after randomization, 5 and 9 weeks after randomization.
Ethics and dissemination
Ethical approval was obtained from the Sichuan Regional Ethics Review of Committee on Traditional Chinese Medicine (Approval ID: 2022KL-068). The results of this study will be distributed through peer-reviewed journals.
