Discovery of the microbiota-gut-brain axis mechanisms of acupuncture for amnestic mild cognitive impairment based on multi-omics analyses: A pilot study

OBJECTIVES

Acupuncture is a promising therapy for amnestic mild cognitive impairment (aMCI). Growing evidence suggest that alterations in the microbiota-gut-brain (MGB) axis contribute to the development and progression of aMCI. However, little is known about whether and how acupuncture change the MGB axis of aMCI individuals.

METHODS

This was a randomized, controlled, clinical trial. Forty patients with aMCI were randomly allocated to either the acupuncture group or the waitlist group. The primary outcome was the change in the Alzheimer's Disease Assessment Scale-Cognitive Scale (ADAS-Cog) score. In addition, multi-omics was performed to detect changes in brain function, gut microbiota, and serum metabolites. Generalized estimating equations were used to estimate the outcomes, and correlational analyses were performed to explore the relationships between the clinical and multi-omics data.

RESULTS

Compared to a mean baseline to week 12 change of -3.94 in the acupuncture group, the mean change in the waitlist group was 1.72 (net difference, -5.66 [95 % CI, -6.98 to -4.35]). Compared to the waitlist group, acupuncture's MGB axis modulatory effect exhibited altered the regional homogeneity values of Frontal_Med_Orb_L, Cingulum_Mid_L, and Frontal_Sup_Medial_L, relative abundance of gut Ruminococcus_sp_AF43_11 and s_Eubacterium_coprostanoligenes, and levels of serum (11E,15Z)-9,10,13-trihydroxyoctadeca-11,15-dienoic acid, dipropylene glycol dimethyl ether, N6-Me-dA, and DPK, which correlated with changes in ADAS-Cog scores.

CONCLUSIONS

Our data imply that acupuncture ameliorates overall cognitive function, along with changes in brain activity, gut microbiota, and serum metabolites, providing preliminary evidence of the mechanisms acting through the MGB axis underlying the effects of acupuncture on aMCI.

Effect of "Tiaoshen" acupuncture technique on mild depression and its underlying mechanism: A randomized controlled trial study protocol

Background

Mild depression is not just a mental disease, but also a serious and long-term public health issue. It affects the quality of life of patients and can quickly develop into major depression. There are currently no effective drug treatments with high efficacy and few adverse reactions. Acupuncture may be an alternative treatment option. Preliminary experiments and practices have demonstrated that "Tiaoshen" acupuncture improves symptoms in patients who have depression, however the underlying data and method remain unclear at present.

Methods

This is a prospective, single-center, single-blind, randomized controlled trial. We plan to recruit 70 participants and randomly assign them to receive "Tiaoshen" acupuncture or traditional acupuncture at a ratio of 1:1. Then, all the participants will receive the appropriate acupuncture treatment for four weeks. The results of the Hamilton Depression Rating Scale (HDSR-24) will serve as the primary outcome, while the results of the Patient Health Questionnaire-9 (PHQ-9) and the World Health Organization Quality of Life Brief Version (WHOQOL-BREF) will serve as secondary outcomes. Evaluations will be conducted at baseline, 1, 2, and 4 weeks after treatment initiation, and 1 and 3 months after treatment completion. The safety of the intervention will be evaluated every week using the Columbia-Suicide Severity Rating Scale (C-SSRS) and the Treatment Emergent Symptoms Scale (TESS). Serum levels of oxidative stress markers 8-iso-prostaglandin F2α (8-iso-PGF2α), superoxide dismutase (SOD), uric acid (UA), and total bilirubin (TBIL) will be measured at baseline and the end of the treatment. We will conduct a statistical analysis of intention to treat (ITT) and conformance to protocol set (PPS) data.

Discussion

This research aims to provide high-quality evidence for the efficacy and safety of "Tiaoshen" acupuncture as a treatment for mild depression. In addition, the mechanism through which acupuncture heals mild depression will be investigated.

Effects of the Prolong Life With Nine Turn-Method Qigong on Fatigue, Insomnia, Anxiety, and Gastrointestinal Disorders in Patients With Chronic Fatigue Syndrome: Protocol for a Randomized Controlled Trial

BACKGROUND

Chronic fatigue syndrome (CFS) is a debilitating multisystem disorder that can lead to various pathophysiological abnormalities and symptoms, including insomnia, gastrointestinal disorders, and anxiety. Due to the side effects of currently available drugs, there is a growing need for safe and effective nondrug therapies. The Prolong Life With Nine Turn (PLWNT) Qigong method is a system of mind-body exercise with restorative benefits that can alleviate the clinical symptoms of CFS and impart a significant inhibitory effect. Various studies have proven the treatment efficacy of PLWNT; however, the impact on insomnia, gastrointestinal disorders, and anxiety in patients with CFS has not yet been investigated.

OBJECTIVE

This study aims to evaluate the efficacy and safety of the PLWNT method in terms of its effects on fatigue, insomnia, anxiety, and gastrointestinal symptoms in patients with CFS.

METHODS

We will conduct a randomized, analyst-blinded, parallel-controlled trial with a 12-week intervention and 8-week follow-up. A total of 208 patients of age 20-60 years will be recruited. The patients will be randomly divided into a PLWNT Qigong exercise group (PLWNT Group) and a control group treated with cognitive behavioral therapy at a ratio of 1:1. Participants from the treatment groups will be taught by a highly qualified professor at the Shanghai University of Traditional Chinese Medicine once a week and will be supervised via web during the remaining 6 days at home, over 12 consecutive weeks. The primary outcome will be the Multidimensional Fatigue Inventory 20, while the secondary outcomes include the Pittsburgh Sleep Quality Index, Gastrointestinal Symptom Rating Scale, Hospital Anxiety and Depression Scale, functional magnetic resonance imaging, gut microbiota, and peripheral blood.

RESULTS

The study was approved by the ethics committee of Shanghai Municipal Hospital of Traditional Chinese Medicine in March 2022 (Ethics Approval Number 2022SHL-KY-05). Recruitment started in July 2022. The intervention is scheduled to be completed in December 2024, and data collection will be completed by the end of January 2025. Over the 3-year recruitment period, 208 participants will be recruited. Data management is still in progress; therefore, data analysis has yet to be performed.

CONCLUSIONS

This randomized trial will evaluate the effectiveness of the PLWNT method in relieving fatigue, insomnia, anxiety, and gastrointestinal symptoms in patients with CFS. If proven effective, it will provide a promising alternative intervention for patients with CFS.

Functional magnetic resonance imaging studies of acupuncture at ST36: a coordinate-based meta-analysis

Background

Functional magnetic resonance imaging (fMRI) has been widely used to investigate the brain effect of acupuncture point Stomach 36 (ST36, Zusanli). However, inconsistent results have hindered our understanding of the neural mechanisms of acupuncture at ST36.

Objective

To perform a meta-analysis of fMRI studies on acupuncture at ST36 to assess the brain atlas of acupuncture at ST36 from available studies.

Method

Based on a preregistered protocol in PROSPERO (CRD42019119553), a large set of databases was searched up to August 9, 2021, without language restrictions. Peak coordinates were extracted from clusters that showed significant signal differences before and after acupuncture treatment. A meta-analysis was performed using seed-based d mapping with permutation of subject images (SDM-PSI), a newly improved meta-analytic method.

Results

A total of 27 studies (27 ST36) were included. This meta-analysis found that ST36 could activate the left cerebellum, the bilateral Rolandic operculum, the right supramarginal gyrus, and the right cerebellum. Functional characterizations showed that acupuncture at ST36 was mainly associated with action and perception.

Conclusion

Our results provide a brain atlas for acupuncture at ST36, which, besides offering a better understanding of the underlying neural mechanisms, also provides the possibility of future precision therapies.

ACURATE: A guide for reporting sham controls in trials using acupuncture

OBJECTIVE

To promote better reporting quality regarding sham acupuncture in clinical trials for a precise appraisal of the adequacy of the sham acupuncture procedure.

METHODS

A three-stage online Delphi survey was conducted to a group of experts. Items with higher than 80% consensus from the initial checklist were selected as the final candidates. Further discussion among the working group was convened to preclude potential redundancy among the items.

RESULTS

A total of 23 experts out of 35 (66%) responded to the Delphi process. The final checklist consists of 23 items in six categories: type of sham acupuncture, details of sham acupuncture manipulation, location of sham acupuncture, treatment regimen, practitioner, and protocol and settings.

CONCLUSION

This paper presents the Acupuncture Controls gUideline for Reporting humAn Trials and Experiments (ACURATE) checklist, an extension of The Consolidated Standards for Reporting of Trials (CONSORT) and to be used along with STandards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) when sham acupuncture needles are used in the study. This checklist focuses on a clear depiction of sham needling procedures to enhance replicability and enable a precise appraisal. We encourage researchers to use ACURATE in trials and reviews involving sham acupuncture to assist reporting sham acupuncture procedures and the related components.

Recent trends in acupuncture for chronic pain: A bibliometric analysis and review of the literature

BACKGROUND

Acupuncture has been increasingly used in patients with chronic pain, yet no bibliometric analysis of acupuncture studies for chronic pain exists.

OBJECTIVES

To investigate the characteristics, hotspots and frontiers of global scientific output in acupuncture research for chronic pain over the past decade.

METHODS

We retrieved publications on acupuncture for chronic pain published from 2011 to 2022 from the Science Citation Index Expanded (SCI-expanded) of the Web of Science Core Collection (WoSCC). The co-occurrence relationships of journals/countries/institutions/authors/keywords were performed using VOSviewer V6.1.2, and CiteSpace V1.6.18 analyzed the clustering and burst analysis of keywords and co-cited references.

RESULTS

A total of 1616 articles were retrieved. The results showed that the number of annual publications on acupuncture for chronic pain has increased over time, with the main types of literature being original articles (1091 articles, 67.5 %) and review articles (351 articles, 21.7 %). China had the most publications (598 articles, 37 %), with Beijing University of Traditional Chinese Medicine (93 articles, 5.8 %) and Evidence-based Complementary and Alternative Medicine ranked first (169 articles, 10.45 %) as the most prolific affiliate and journal, respectively. Liang FR was the most productive author (43 articles), and the article published by Vickers Andrew J in 2012 had the highest number of citations (625 citations). Recently, "acupuncture" and "pain" appeared most frequently. The hot topics in acupuncture for chronic pain based on keywords clustering analysis were experimental design, hot diseases, interventions, and mechanism studies. According to burst analysis, the main research frontiers were functional connectivity (FC), depression, and risk.

CONCLUSION

This study provides an in-depth perspective on acupuncture for chronic pain studies, revealing pivotal points, research hotspots, and research trends. Valuable ideas are provided for future research activities.

Acupuncture on mild cognitive impairment: A systematic review of neuroimaging studies

Mild cognitive impairment (MCI) is a multifactorial and complex central neurodegenerative disease. Acupuncture appears to be an effective method for cognitive function improvement in MCI patients. Neural plasticity remaining in the MCI brain implies that acupuncture-associated benefits may not be limited to the cognitive function. Instead, neurological alternations in the brain play a vital role in corresponding to the cognitive improvement. However, previous studies have mainly focused on the effects of cognitive function, leaving neurological findings relatively unclear. This systematic review summarized existing studies that used various brain imaging techniques to explore the neurological effect regarding acupuncture use for MCI treatment. Potential neuroimaging trials were searched, collected, and identified independently by two researchers. Four Chinese databases, four English databases, and additional sources were searched to identify studies reporting the use of acupuncture for MCI from the inception of databases until 1 June 2022. Methodological quality was appraised using the Cochrane risk-of-bias tool. In addition, general, methodological, and brain neuroimaging information was extracted and summarized to investigate the potential neural mechanisms by which acupuncture affects patients with MCI. In total, 22 studies involving 647 participants were included. The methodological quality of the included studies was moderate to high. The methods used included functional magnetic resonance imaging, diffusion tensor imaging, functional near-infrared spectroscopy, and magnetic resonance spectroscopy. Acupuncture-induced brain alterations observed in those patients with MCI tended to be observable in the cingulate cortex, prefrontal cortex, and hippocampus. The effect of acupuncture on MCI may play a role in regulating the default mode network, central executive network, and salience network. Based on these studies, researchers could extend the recent research focus from the cognitive domain to the neurological level. Future researches should develop additional relevant, well-designed, high-quality, and multimodal neuroimaging researches to detect the effects of acupuncture on the brains of MCI patients.

Acupuncture for mild cognitive impairment: A systematic review with meta-analysis and trial sequential analysis

Background

There is insufficient evidence to support the use of acupuncture for mild cognitive impairment (MCI), and there is no consensus on its efficacy. This review aimed to determine the acupuncture effect in patients with MCI.

Methods

Relevant and potentially eligible randomized controlled trials (RCTs) of acupuncture for MCI were obtained from four Chinese databases, four English databases, and additional resources up to 1 August 2022. The primary outcome was the improvement in overall cognitive function (OCF). Secondary outcomes were improved memory function (MF) and activities of daily living (ADLs). The revised Cochrane collaboration risk of bias (ROB) assessment tool (ROB 2.0) was applied to evaluate their methodological quality. The Review Manager software v 5.4 was used for analyses. Trial sequential analysis (TSA) 0.9.5.10 β software was used to estimate the required sample size and test the reliability of the pooled outcome. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool.

Results

This meta-analysis included 11 RCTs with a total of 602 patients. The methodological quality of all trials was moderate. Low-quality evidence showed that acupuncture significantly improved OCF (Mini-Mental State Examination (MMSE): mean difference (MD) = 1.22, 95% confidence interval (CI): 0.78-1.66; the Montreal Cognitive Assessment Scale (MoCA): MD = 1.22, 95% CI: 0.47-1.97). In subgroup analyses, it was revealed that acupuncture significantly increased OCF in patients with MCI when compared to conventional medicine (CM) and sham acupuncture (SA). TSA's findings indicated that the evidence of improving OCF with acupuncture for patients with MCI was conclusive. Meanwhile, there is no statistical difference in the improvement of MF and ADL between acupuncture and CM. TSA showed that the evidence of improving MF and ADL for patients who had MCI and received acupuncture was inconclusive. The shreds of evidence of improving MF and ADL were ranked from low to critically low.

Conclusion

Acupuncture appears to be an effective clinical application method for improving OCF in patients with MCI. However, due to low-quality evidence, more relevant and high-quality research is needed in this field.

The Central Response of Electroacupuncture on Trigeminal Neuralgia Based on Resting-State Functional Magnetic Resonance Imaging: A Protocol for a Pre-Experimental, Single-Centre, Randomized, Controlled Trial

Objective

To verify the efficacy of electroacupuncture (EA) on classical trigeminal neuralgia (CTN), and to observe the brain functional status of patients with CTN and the intervention effects of EA on brain function by resting-state functional magnetic resonance imaging (rs-fMRI).

Methods and Analysis

Thirty CTN patients will be randomly divided into EA combined with carbamazepine group and carbamazepine group in 2:1 ratio by using a random number table. Patients in EA combined with carbamazepine will receive EA treatment and carbamazepine for four weeks. The carbamazepine group will only receive carbamazepine treatment. VAS (visual analogue scale), HAMA (Hamilton Anxiety Scale), HAMD (Hamilton Depression Scale) and SF-36 (short form 36 health survey) will be performed before, after four-week treatments and at three-month follow-up in CTN patients. Six CTN patients will be randomly selected from EA combined with carbamazepine group and carbamazepine group, respectively, before treatment, and twelve paired healthy participants will be recruited at the same time. The twelve CTN patients will be scanned by rs-fMRI before and after treatment, and the healthy participants will be scanned by rs-fMRI only at baseline. Regional homogeneity (ReHo) and amplitude of low-frequency fluctuation (ALFF) analysis will be carried out to compare the dysfunctional brain regions between CTN patients and healthy participants, as well as the differences between two groups of patients with CTN after treatment.

Effects of Acupuncture on Vascular Cognitive Impairment with No Dementia: A Randomized Controlled Trial

Background:

Acupuncture has been used for treating vascular cognitive impairment, but evidence for its effectiveness remains limited.

Objective:

This single-center, patient-accessor blinded, randomized controlled trial was designed to assess whether acupuncture could improve the cognitive function of patients with vascular cognitive impairment with no dementia (VCIND).

Methods:

120 VCIND patients were randomly assigned to the electro-acupuncture (EA) or sham acupuncture (SA) group at a 1 : 1 ratio, with treatment conducted thrice weekly for 8 weeks. The primary outcome was the changes of cognitive function measured by the Montreal Cognitive Assessment (MoCA) from baseline to week 8. The secondary outcomes included the scores of the Mini-Mental State Examination (MMSE), the Modified Barthel Index (MBI) and the Self-rating Depression Scale (SDS). Follow-up assessments were performed with MoCA and MMSE at week 16 and 32. Linear mixed-effects models were used for analysis and all statistical tests were two-sided.

Results:

The results showed that patients in the EA group had a significantly greater improvement in MoCA score (23.85±4.18) than those in the SA group (21.48±4.44) at week 8 (95% CI = 0.80, 3.92, p = 0.04), as well as higher MoCA scores over time (p < 0.001 for interaction). Patients who received EA showed a greater increase in MMSE scores (26.41±3.47) than those who received SA (24.40±3.85) along 8 weeks (95% CI = 0.69, 3.34, p = 0.004). However, results diminished over time. No serious adverse events occurred during the trial.

Conclusion:

EA is a safe and effective technique to improve cognition over the short term of 8 weeks in VCIND patients.

Comparison of Effects and Brain-Gut Regulatory Mechanisms of Acupuncture and Flunarizine for Migraine: Study Protocol for a Randomized Controlled Trial

Background

As a central nervous system disease, migraine often coexists with gastrointestinal disorders, which suggests a disruption of brain-gut regulation. Clinical studies have confirmed that acupuncture and flunarizine not only alleviate migraine attacks but also substantially inhibit accompanying gastrointestinal symptoms. However, it is still not clear how acupuncture and flunarizine regulate the interactions of brain, gut, and microbiome. Therefore, this study will combine neuroimaging technology and gut microbiota detection technology to explore and compare the effects and brain-gut modulating mechanisms of acupuncture and flunarizine for migraine.

Methods

This randomized clinical trial will recruit 66 patients with migraine without aura. Participants will be randomly assigned in a 1 : 1 ratio to an acupuncture group or a control group. The acupuncture treatment strategy is based on experience from our previous study and consensus meetings with clinical experts. Patients will receive 12 sessions of manual acupuncture treatment (once every other day to a total of three times per week, followed by a 2-day break). Flunarizine will be administered at a dose of 5 mg daily in the control group. Participants in both groups will receive treatment for a period of 4 weeks. The primary outcome is the change in frequency of migraine attacks, and the secondary outcomes include the changes in migraine days (days on which migraine attacks occurred), average migraine severity, gastrointestinal symptoms, psychiatric symptoms, and quality of life. Fresh stool samples will be collected, and 16S ribosomal RNA gene sequencing analysis will be used for gut microbiota. Magnetic resonance imaging will be applied to detect between-group changes in brain function. The abovementioned indicators will be collected at baseline, after a 4-week intervention, and at the 12-week follow-up. Discussions. From the perspective of brain-gut regulatory mechanisms, we will combine brain neuroimaging and gut microbiological data to partially reveal the similarities and differences of acupuncture and flunarizine on the treatment of migraine. The trial is registered with ChiCTR2000034417.

Does patient's expectation benefit acupuncture treatment?: A protocol for systematic review and meta-analysis

BACKGROUND

Patients' expectation to treatment response is one source of placebo effects. A number of randomized controlled trials (RCTs) reported that expectation benefits to acupuncture treatment, while some did not. Previous systematic reviews failed to draw a confirmative conclusion due to the methodological heterogeneity. It is necessary to conduct a new systematic review to find out whether expectation can influence acupuncture outcomes.

METHODS

We systematically search English and Chinese databases from their inception to 3rd October, 2020, including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Chinese BioMedical Literature Database (CBM), Chinese National Knowledge Infrastructure (CNKI), and Chinese Science and Technology Periodical Database (VIP). RCTs that evaluated the relationship between expectation and treatment response following acupuncture for adults will be included. Study selection, data extraction, and risk of bias assessment will be conducted independently. Risk of bias will be assessed by the Cochrane risk of bias assessment tool. Data synthesis will be performed by Review Manager (RevMan) software if the data is suitable for synthesis.

RESULTS

This systematic review will provide evidence that whether patients' expectation impacts on the therapeutic effects of acupuncture. This protocol will be performed and reported according to the Preferred Reporting Items from Systematic Reviews and Meta-analysis Protocols (PRISMA-P) statement. The findings of this review will be disseminated through peer-reviewed publications and conference presentations.

CONCLUSION

This systematic review aims to assess whether a higher level of patient's expectation contributes to a better outcome after acupuncture treatment, and in which medical condition this contribution will be more significant.

Acupuncture for pain relief of women undergoing transvaginal oocyte retrieval: A meta analysis and systematic review protocol

BACKGROUND

Pain during oocyte retrieval, which can make the in-vitro fertilization process an unpleasant experience, is becoming a common problem. Although there are many analgesic methods available in the clinical setting, they are not therapeutically equivalent, and some are associated with varying adverse reactions. In recent years, acupuncture analgesia has been used in the perioperative period of oocyte retrieval because of its perceived efficacy and safety. The purpose of this systematic review and meta-analysis is to provide evidence that acupuncture is effective in the treatment of vaginal oocyte retrieval pain.

METHODS

Electronic searches of the following six databases will be conducted by two qualified reviewers: MEDLINE, EMBASE, China National Knowledge Infrastructure, Chinese Biomedical Medicine database, VIP database and Wanfang database. Three clinical trial registries will also be searched: World Health Organization International Clinical Trial Registry Platform, Chinese Clinical Trial Registry, Cochrane Central Register of Controlled Trials and ClinicalTrials.Gov. All searches will cover the period from inception of the database/registry to March 2020 and will be limited to publications in English and Chinese. Data identification, data selection, data extraction, and bias risk assessment will be conducted independently by3ν two or more qualified reviewers, including those who selected the studies. Visual analogue scale scores will be calculated as the primary outcome. Secondary outcomes will include results of other subjective pain rating scales, including Likert scales or other defined numerical or non-numerical scales, self-assessed by patients before, during, and after oocyte retrieval. We will use STATA software (Version 16) to perform meta-analyses, and the Grading of Recommendations, Assessment, Development and Evaluations framework to grade the quality of evidence. If quantitative analysis is not available, a systematic narrative synthesis will be provided.

Systematic review and meta-analysis of effects of acupuncture on pain and function in non-specific low back pain

OBJECTIVE

To assess the effectiveness of acupuncture for non-specific low back pain (NSLBP) through systematic review of published randomised controlled trials (RCTs).

METHODS

Studies were identified in electronic databases from their inception to February 2018, and were grouped according to the control interventions. The outcomes of interest were pain intensity and disability. Methodological quality was evaluated using the Cochrane risk-of-bias criteria and the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA) checklist. The review was reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines.

RESULTS

25 trials (n=7587 participants) were identified and included in a meta-analysis. The results showed that acupuncture was more effective at inducing pain relief than: no treatment (standardised mean difference (SMD) -0.69, 95% CI -0.99 to -0.38); sham acupuncture in the immediate term (SMD -0.33, 95% CI -0.49 to -0.18), short term (SMD -0.47, 95% CI -0.77 to -0.17), and intermediate term (SMD -0.17, 95% CI -0.28 to -0.05); and usual care in the short term (SMD -1.07, 95% CI -1.81 to -0.33) and intermediate term (SMD -0.43, 95% CI -0.77 to -0.10). Also, adjunctive acupuncture with usual care was more effective than usual care alone at all time points studied. With regard to functional improvement, the analysis showed a significant difference between acupuncture and no treatment (SMD -0.94, 95% CI -1.57 to -0.30), whereas the other control therapies could not be assessed.

CONCLUSION

We draw a cautious conclusion that acupuncture appears to be effective for NSLBP and that acupuncture may be an important supplement to usual care in the management of NSLBP.

Different Acupuncture Therapies for Allergic Rhinitis: Overview of Systematic Reviews and Network Meta-Analysis

OBJECTIVE

To evaluate the quality of methodologies used in previous systematic reviews (SRs) and compare efficacy of different acupuncture therapies for allergic rhinitis.

METHODS

Seven electronic databases were searched for systematic reviews (SRs) performed on different acupuncture therapies for allergic rhinitis from inception to 15 November 2019. The AMSTAR2 instrument was employed to assess the methodological quality of included SRs. Eligible randomized controlled trials (RCTs) were selected from the included systematic reviews. We also included recent RCTs published by 15 November 2019. Cochrane risk of bias tool was utilized to determine risk of bias of the included RCTs. Pairwise meta-analyses were performed using the random-effects model. Network meta-analysis of the included RCTs was carried out using frequentist framework.

RESULTS

We identified 2 SRs with low quality and 18 SRs with very low quality, both of which contained 33 eligible RCTs (n = 3769). Most of these studies had unclear risk of bias. On the basis of ranking probability, NMA analysis showed that acupuncture at the sphenopalatine ganglion acupoint (OR: 1.31, 95% CI 1.07 to 1.61) had the highest probability of improving global allergic rhinitis symptoms, followed by San-Fu-Tie (OR: 1.17, 95% CI 1.08 to 1.27), manual acupuncture (OR:1.15, 95% CI 1.07 to 1.24) compared with conventional western medicine treatment. Moreover, direct comparison of the follow-up period showed that the clinical outcomes of acupuncture and related therapies at three-month (OR:1.34, 95% CI 1.17 to 1.55), six-month (OR: 1.31, 95% CI 1.10 to 1.57), and twelve-month (OR: 1.30, 95%CI 1.11 to 1.53) follow-up were better than those of traditional western medicine.

CONCLUSION

These results indicate that for patients with allergic rhinitis who are unresponsive to conventional western medicine or cannot tolerate the side effects, acupuncture at the sphenopalatine ganglion acupoint is an effective alternative therapy. Further studies are advocated to deeply explore methodological quality of SRs by incorporating high-quality RCTs.

Acupuncture for Relief of Gag Reflex in Patients Undergoing Transoesophageal Echocardiography-A Protocol for a Randomized Placebo-Controlled Trial

Background: Gagging during transesophageal echocardiography examination (TEE) can be distressing and even dangerous for patients. The needling of acupuncture point CV24 was described to be effective in reducing the gag reflex during TEE in patients with ischemic stroke or transient ischemic attack. Methods: We describe a proposal for a prospective, randomized, patient, practitioner and assessor-blinded, single-center trial with two arms/groups; real acupuncture will be compared to placebo acupuncture. A total of 60 (30 per group) patients scheduled for elective TEE in order to exclude a cardiac embolic source, endocarditis or for valve failure evaluation will be recruited according to patients' selection criteria and receive either indwelling fixed intradermal needles at acupoints CV24 and bilateral PC6 or placebo needles at the same areas. Patients, the practitioners who will perform the TEE procedure, and the assessor of the outcome measures will be unaware of the group's (real or placebo) allocation. Results: The primary outcome is the intensity of gagging, measured using verbal rating scale (VRS-11) from 0 = no gagging to 10 = intolerable gagging. Secondary outcomes include the incidence of gagging, the use of rescue medication, patients' satisfaction with relief of unwanted side effects during TEE procedure, success of patients' blinding (patients' opinion to group allocation), heart rate and oxygen saturation measured by pulse oxymetry. Conclusions: To study the effects of acupuncture against gagging during TEE, we test the needling of acupoints CV24 and PC6 bilaterally. A placebo acupuncture is used for the control group. Trial registration number: NCT NCT0382142.

Effects of Electroacupuncture Therapy and Cognitive Behavioral Therapy in Chronic Insomnia: A Randomized Controlled Study

Objective

To evaluate the efficacy of spirit-regulating electroacupuncture (EA), cognitive behavioral therapy (CBT), and combined EA/CBT to treat insomnia.

Methods

In this prospective clinical study, patients were randomly assigned to receive EA, CBT, or EA/CBT. Outcomes were assessed using PSQI, ISI, ESS, DBAS-16, HAM-A, and HAM-D at two- and four-week follow-up.

Results

Overall, the PSQI and ISI scores decreased after treatment in all three groups. At two-week follow-up, the EA/CBT group obtained lower PSQI and ISI scores than the EA group. The daytime functional factor score in the EA group was lower than that of the CBT group after the second week of treatment, and the EA/CBT PSQI score was lower than that of the CBT group on the second week of follow-up. In comparison with baseline, the EA group had a decreased ESS score after the second and fourth weeks of treatment, while the ESS score increased in the CBT group after the fourth week of treatment. ESS scores were unchanged following treatment in the EA/CBT group. After the second and fourth weeks of treatment, the ESS scores from the CBT group were higher than the EA group. The DBAS-16 decreased in the CBT and EA/CTB groups, while the EA group had a higher DBAS-16 score. In all three groups, HAM-A and HAM-D scores decreased after treatment; the EA/CBT HAM-A and HAM-D scores were lower than the other two groups.

Conclusion

1. Spirit-regulating EA therapy is effective. In terms of improving sleep quality and mood, EA has the same effect as CBT and can improve daytime function earlier. 2. The curative effect of the EA/CBT group lasts longer than that of the EA group, and EA/CBT is better at improving daytime function compared to CBT alone and better at improving mood compared to CBT or EA alone.

The effectiveness and safety of acupuncture for patients with atopic eczema: a systematic review and meta-analysis

OBJECTIVE

The aim of this study was to systematically assess the effectiveness and safety of acupuncture for patients with atopic eczema (AE).

METHODS

Two reviewers searched 13 databases from their inception through 31 July 2018 for randomized controlled trials (RCTs) of patients with AE. Dichotomous data and continuous data were analyzed using risk ratio (RR) and mean difference (MD), respectively, with 95% confidence intervals (CIs).

RESULTS

A total of eight RCTs (with 434 participants) were included. The results of one included RCT showed that acupuncture was better than no treatment at reducing itch intensity measured using a visual analogue scale in patients with AE. The combined results of six RCTs showed that acupuncture was better than conventional medicine at reducing the eczema area and severity index (EASI) (MD: -1.89, 95% CI: -3.04 to -0.75, I2: 78%) and the combined results of seven RCTs showed that acupuncture was better than conventional medicine in terms of global symptom improvement (RR: 1.59, 95% CI: 1.20 to 2.11, I2: 55%) in AE. We had insufficient data to show significant effects of acupuncture on quality of life and AE recurrence rate. No severe adverse events were found related to acupuncture.

LIMITATIONS

The included RCTs had some methodological limitations, and most of the included trials were conducted in China. This analysis only included studies that compared acupuncture alone with no treatment or positive control (conventional medicine), so the specific effects of acupuncture could not be evaluated.

CONCLUSION

Acupuncture might be effective at reducing itch intensity and may be more effective than conventional medicine at reducing EASI and improving the global symptoms of AE.

The effect and safety of acupuncture on patients with functional constipation: Protocol for a systematic review and meta-analysis of high quality RCTs

BACKGROUND

Functional constipation (FC) is a prevalent clinical disease that affects a considerable proportion of the population of all ages. Persistent FC significantly reduces quality of life and influences physical and emotional well-being, as well as consumes many substantial healthcare resources. Acupuncture originates from Traditional Chinese Medicine (TCM), and emerging evidence of several randomized controlled trials (RCTs) published suggest that acupuncture has positive effects for FC. Since 2019, several new results of high quality RCTs about acupuncture treatment for FC have been published. Thus a systematic review will be designed to appraise the effectiveness and safety of acupuncture for improvement of FC in patients based on high quality RCTs.

METHODS

We carried out a rigorous literature search in English and Chinese electronic database from inception to present. Two reviewers will identify relevant studies, extract and manage trial information, and then assess the risk of bias in included studies by the Cochrane risk of bias assessment tool. Only high quality RCTs will be included. Data will be synthesized by either fixed-effects or random-effects model regarding to a heterogeneity test. The primary outcome measurement will be the change from baseline in mean complete spontaneous bowel movements and stool form. The secondary outcomes involved disappearance rate of symptoms, proportion of responders, mean transit time, health-related quality of life, and safety of intervention. Meta-analysis will be performed by using Cochrane's RevMan software.

RESULTS

This systematic review will summarize high quality clinical evidence to assess and appraise the effectiveness and safety of acupuncture treatment for FC patient.

EXPECTED CONCLUSION

This systematic review and meta-analysis will provide evidence to determine whether acupuncture treatment is an effective and safe therapy for the prevention and treatment of FC compared with medication treatment.

Acupuncture for the treatment of lower limb diabetic peripheral neuropathy: a systematic review

OBJECTIVE

To examine evidence for acupuncture interventions in the management of diabetes-related peripheral neuropathy (DPN) symptoms.

METHODS

Five electronic databases were searched up to June 2017 for studies that included participants with symptoms of DPN, used an acupuncture intervention, and reported before-and-after DPN-related outcome measures. Two reviewers independently performed the data extraction. The level of homogeneity was assessed, and studies were appraised using the Cochrane Risk of Bias tool, the STRICTA guidelines for acupuncture reporting and the NICMAN scale for acupuncture quality.

RESULTS

Ten studies with 432 participants were included: three randomised controlled trials (RCTs), two pilot RCTs, three uncontrolled clinical trials, one quasi-RCT and one prospective case series. Improvements in DPN pain symptoms were reported by all studies. Heterogeneity of outcome measures prevented a meta-analysis. Variations were found in needle retention time and point selection, as well as total number and frequency of treatments. Common acupuncture point selections were ST36 and SP6. Half of the studies used local point selection. Studies conducted outside China had better acupuncture reporting and quality according to the STRICTA checklist and NICMAN scales, respectively. Risk of bias was high or unclear in the majority of studies for all domains except attrition bias.

CONCLUSIONS

Acupuncture for DPN appears to improve symptoms. However, the application of acupuncture varies greatly, and the quality of included studies was generally low. Available studies have varying methodologies and different outcome measures. Further, suitably powered studies using appropriate DPN outcome measures are required.

Randomized controlled trials on acupuncture for migraine: research problems and coping strategies

BACKGROUND

Acupuncture clinical trials have achieved certain results in verifying the efficacy and safety of acupuncture in recent years. However, there are still some shortcomings in trial design, data processing that obstructed the objective evaluation.

METHODS

This article tried to summarize the common problems in randomized controlled trials evaluating acupuncture treatment for migraine. We searched seven databases from inception to Oct 19th, 2017 and carried out a systematic review. According to this meta-analysis, we collected and synthesized the common problems and then summarized the main shortcomings.

DISCUSSION

From aspects of trial design, statistical analysis and article writing, this paper illustrated the problems with examples, discussed the probable causes and accordingly put forward some recommendations to standardize the trial design, data processing and article reporting.

A Randomized, Double-Blind, Sham-Controlled Study Assessing Electroacupuncture for the Management of Postoperative Pain after Percutaneous Nephrolithotomy

INTRODUCTION

Percutaneous nephrolithotomy (PCNL) is the gold standard procedure for large renal calculi but postoperative (PO) pain remains a concern. Modifications of the PCNL technique and intraoperative and PO strategies have been tested to reduce pain. PO pain control reducing risk of long-term pain medication and narcotic use is of considerable importance. Acupuncture is a common medical procedure shown to alleviate PO pain. Some benefits are that it is nonpharmacologic, easy to administer, and safe. The purpose of this study was to evaluate the effects of electroacupuncture (EA) on PO pain in patients undergoing PCNL.

MATERIALS AND METHODS

This was a randomized, double-blind, sham-controlled study. The study was Institutional Review Board approved and performed under standard ethical guidelines. Fifty-one patients undergoing PCNL by a single surgeon were randomized to one of the three groups: true EA (n = 17), sham EA (SEA, n = 17), and no acupuncture (control, n = 17). The EA and SEA were performed by a single licensed acupuncturist <1 hour before operation. PCNL was performed without the use of intraoperative nerve block(s) or local anesthetic. Pain scores (visual analog scale [VAS]), narcotic use (morphine equivalents), and side effects were recorded at set intervals postoperatively.

RESULTS

Mean VAS scores for flank and abdomen pain were lower at all time periods in the EA compared with the SEA and control groups. Mean cumulative opioid usage was lower in the EA group immediately postoperatively compared with both SEA and control groups. Two patients in the EA group did not require any PO narcotics. No differences between groups were found for PO nausea and vomiting. No adverse effects of EA or SEA were noted.

CONCLUSIONS

EA significantly reduced PO pain and narcotic usage without any adverse effects after PCNL. This promising treatment for managing PO pain warrants further investigation.

The Clinical Effectiveness of Acupuncture for Pain Relief – you can be Certain of Uncertainty

Nowadays the volume of published research is so overwhelming that practitioners are turning to expert groups to interpret and summarise research for them. This paper critically reviews the processes used to establish one-sentence statements about the effectiveness of acupuncture for pain relief. Some one-sentence statements claim that acupuncture is not clinically effective because systematic reviews of clinical trials find similar amounts of pain relief between sham acupuncture and real acupuncture. However, these one-sentence statements fail to account for shortcomings in clinical trials such as inadequate doses and inappropriate acupuncture technique. Establishing the physiological intention of acupuncture and developing criteria to assess whether this has been achieved in trials will help to overcome some of these problems in future trials. In addition, shortcomings in systematic review methodology such as imprecise inclusion criteria, comparisons of heterogeneous study populations and imprecise definitions of acupuncture have resulted in discrepancies in vote counting of outcomes between review groups. Recognition of these issues has produced a shift in favour of acupuncture in recent systematic reviews and meta-analyses. It is hoped that this will be reflected in a reappraisal of some of the negative one-sentence statements about the effectiveness of acupuncture for pain relief.

Guidelines for Case Reports of Adverse Events Related to Acupuncture

Numerous case reports of adverse events of acupuncture have been published, mostly in journals which are not related to acupuncture. The authors usually have no training in acupuncture. In principle, case reports on adverse events are of value as an aid for learning. They can only achieve this effect if useful information is provided. In the case of acupuncture related adverse events and complications, basic information about the patient and the therapist as well as the treated acupuncture points and topographical regions and the needling technique are desirable. This article offers suggestions on what details should be included in a case report on adverse events related to acupuncture.

Consensus for Dry Needling for Plantar Heel Pain (Plantar Fasciitis): A Modified Delphi Study

Hypothesis

Plantar heel pain (plantar fasciitis) is a common and disabling condition. A variety of treatment options are available to patients with plantar heel, however the evidence for these treatments is generally weak and the best way to manage plantar heel pain remains unclear. Trigger point dry needling is increasingly used as an adjunct therapy for musculoskeletal pain. In patients with plantar heel pain this technique is thought to improve muscle activation patterns, increase joint range of motion and alleviate pain. However, there have been no randomised controlled trials that have evaluated the effectiveness of dry needling for plantar heel pain.

Methods

In order to develop a treatment protocol to evaluate the effectiveness of dry needling for plantar heel pain we conducted a three stage modified Delphi process using a web-based survey technique. Over a series of three iterations, 30 experts (participants) worldwide indicated their level of agreement on specific issues relating to the use of dry needling for plantar heel pain including their treatment rationale, needling details and treatment regimen. Consensus for a dry needling protocol for plantar heel pain was achieved when >60% of participants (IQR ≤ 1.0 category on 5-point Likert scale) agreed the protocol was adequate.

Results

The response rate was 75% (n=30), 100% (n=30) and 93% (n=28) in the first, second and third rounds respectively. Round 1 helped generate a list of 10 items that were deemed important for developing a dry needling protocol for plantar heel pain. These 10 items were subsequently presented in Round 2. Of these, 5 of the 10 items met the criteria to be included in a dry needling protocol for plantar heel pain that was presented in the final round, Round 3. Items that did not meet the criteria were either removed or amended and then presented in Round 3. In the final round, 93% of participants (IQR range = 1) agreed the proposed dry needling protocol for plantar heel pain was adequate. The protocol can now be used in future research projects designed to evaluate the effectiveness of dry needling for plantar heel pain.

Improvement of Menopausal Symptoms with Acupuncture Not Reflected in Changes to Heart Rate Variability

Hypothesis

Studies indicate that menopausal symptoms are relieved by acupuncture. Additional studies have suggested that acupuncture may affect heart rate variability (HRV). This paper reports a pilot study that investigated whether menopausal symptoms responded to acupuncture, and if changes in the spectral analysis of HRV, either suppression of low frequency or augmentation of high frequency bands, corresponded with symptom report.

Methods/interventions

12 healthy menopausal subjects were enrolled in this feasibility study. At baseline, subjects were experiencing moderately distressing menopausal symptoms, scoring at least 22 of a possible 44 points on the Menopausal Rating Scale. 10 traditional Chinese medicine-based, protocol acupuncture treatments were administered over a 4 week period, three times a week for 2 weeks, followed by twice a week for 2 weeks.

Outcome measures

Menopausal Rating Scale questionnaire, 11 menopausal symptoms were evaluated on a zero to four severity scale via self-administered daily checklist for 4 weeks. Dynamic measures of HRV (autoregressive model) were captured before, during and after acupuncture at each session. Spectral analysis of the heart rate was used to compute power in the low frequency and high frequency bands, and their ratio.

Results

All subjects complied fully with the protocol without any reported adverse events. While all 11 symptoms showed significant improvement, and one HRV measure changed, on average over the study period, there was essentially no support for a relationship between HRV, menopausal symptom report and acupuncture intervention.

Quality of Reporting of Randomised Controlled Trials of Acupuncture for Neurological Diseases Conducted in China

Objectives

To investigate the quality of reporting for randomised controlled trials of acupuncture for neurological disorders conducted in China before and after the implementation of the Consolidated Standards of Reporting Trials (CONSORT) and Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA) guidelines.

Methods

The quality of reporting for included papers was assessed against a subset of criteria adapted from CONSORT and STRICTA. CONSORT and STRICTA were developed in 1996 and 2001, respectively. Thus, for the date of publication we selected 2-year periods, at 5-yearly intervals: 1994–1995; 1999–2000; 2004–2005 and 2009–2010. These selections cover the periods before the publication dates of both guidelines (1996, 2001) and at least 3 years afterwards, and provide reasonably up-to-date data. We calculated the total score for each guideline and compared reported differences during different date ranges.

Results

For CONSORT items (maximum score 8), there was evidence of a slight improvement in reporting between 1994–1995 and 1999–2000 combined (2.5±0.6) and 2004–2005 and 2009–2010 combined (3.0±0.9) (difference 0.5, 95% CI 0.2 to 0.8). For STRICTA items (maximum score 17), there was evidence of a slight improvement in reporting between 1994–1995 and 1999–2000 combined (8.9±1.8) and 2004–2005 and 2009–2010 combined (10.3±1.6) (difference 1.4, 95% CI 0.9 to 1.9).

Conclusions

The quality of reporting for studies of acupuncture for neurological disorders has generally improved since the implementation of STRICTA and CONSORT guidelines.

Efficacy of ah shi Point Acupuncture on Acne Vulgaris

Background

Ah shi point acupuncture involves inserting needles at painful or pathological sites.

Objective

To evaluate the efficacy of ah shi point and general acupuncture point treatment of acne vulgaris.

Methods

36 subjects were recruited and randomised in a double-blind (patient-blind and observer-blind) controlled trial to receive acupuncture either at general acupuncture points only, or at both general acupuncture points and ah shi points 12 times over 6 weeks. The subjects were evaluated using the following outcome measurements: an inflammatory lesion count, a quality-of-life scale (Skindex-29) and a subjective symptom score.

Results

After 12 treatment sessions, there was a significant reduction in the inflammatory acne lesion counts, the Skindex-29 scores and the subjective symptom scores from baseline in both groups, but no significant difference between groups.

Conclusions

Acupuncture treatment of moderate acne vulgaris was associated with reduction of inflammatory lesions and improvement of the quality of life.

The Application of Auriculotherapy to the Treatment of Chronic Spontaneous Urticaria: A Systematic Review and Meta-analysis

Auriculotherapy has been extensively used for chronic spontaneous urticaria in China. However, the evidence of its effectiveness and safety for the treatment of chronic spontaneous urticaria is insufficient. Hence, we conducted this study to compare auriculotherapy or auriculotherapy joint treatment with Western medicine for the cure of chronic spontaneous urticaria. This meta-analysis of seven randomized controlled trials showed that auriculotherapy or auriculotherapy joint treatment was significantly superior to Western medicine in curing clinical signs and symptoms of chronic spontaneous urticaria [odds ration (OR), 2.61; 95% confidence interval (CI), 1.54-4.43; p = 0.0004) and also better in total effect rate (OR, 3.81; 95% CI, 2.07-7.01; p＜0.0001). But, auriculotherapy or auriculotherapy joint treatment was similar to Western medicine in improving clinical signs and symptoms of chronic spontaneous urticaria (OR, 0.74; 95% CI, 0.35-1.56; p = 0.42). Auriculotherapy or auriculotherapy joint treatment was safer than Western medicine for curing chronic spontaneous urticaria (OR, 0.26; 95% CI, 0.09-0.80; p = 0.02). Auriculotherapy alone or auriculotherapy joint treatment appears to be more effective and safer than Western medicine that contains antihistamines in the treatment of chronic spontaneous urticaria. However, these findings should be interpreted with caution due to the unclear risk bias of methodological quality, and further studies with large-scale, better, and more rigorously designed protocol are necessary to prove these findings.

Effects of single-point acupuncture (HT7) in the prevention of test anxiety: Results of a RCT

Background

The number of students using neuro enhancement to improve their performance and to prevent test anxiety is increasing. The acupuncture point Heart 7 (HT7) has been described as being prominent in reducing states of anxiety.

Methods

We conducted a randomized placebo-controlled, two-armed pilot trial to investigate the efficacy of a single-point acupuncture treatment at bilateral HT7 compared to sham laser acupuncture on test anxiety. Test anxiety was induced applying the standardised protocol of the Trier Social Stress Test. Outcome measures included saliva samples analysed for cortisol and amylase, anxiety questionnaires and heart rate variability.

Results

Twenty-five male subjects (age 28 ± 5 years) were allocated to either verum acupuncture (n = 12) or sham laser acupuncture (n = 13). Cortisol peaked 20 min after the stress test (2-fold, 18.11 ± 2 nmol/l) and amylase 10 min after (2-fold, 259 ± 49 U/ml) with no difference between groups. There were no differences between groups regarding either anxiety questionnaires or physiological parameters. Compared to reference data (3-fold increase in cortisol), increase in stress hormones and heart rate seemed somewhat reduced.

Conclusions

Acupuncture may be a possible approach for the treatment of anxiety. Due to the lack of a no control treatment group, we cannot determine the magnitude of possible specific needle effects at HT7 to promote specific effects in the neuroendocrine system. Finally this study only examines the efficacy of a single time treatment.

Acupuncture for Lumbar Disc Herniation: A Systematic Review and Meta-Analysis

Objective

To evaluate evidence for the effectiveness of acupuncture in the treatment of lumbar disc herniation (LDH).

Methods

Electronic databases were searched to identify randomised controlled trials (RCTs) of acupuncture for LDH. A meta-analysis was conducted using RevMan 5.3 and the evidence level was assessed using GRADE methodology.

Results

Thirty RCTs involving 3503 participants were included in the study. Meta-analysis showed that acupuncture had a higher total effective rate than lumbar traction (RR=1.1, 95% CI 1.05 to 1.15; p<0.001), ibuprofen (RR=1.24, 95% CI 1.03 to 1.48; p=0.02), diclofenac sodium (RR=1.44, 95% CI 1.24 to 1.67; p<0.001) and meloxicam (RR=1.16, 95% CI 1.03 to 1.31; p=0.01). Acupuncture was also better than lumbar traction (SMD −1.33, 95% CI −1.82 to −0.84; p<0.001) and diclofenac sodium (SMD −1.36, 95% CI −2.59 to −0.13; p=0.03) in terms of visual analogue scale (VAS) scores, and better than lumbar traction (SMD 0.96, 95% CI 0.48 to 1.45; p=0.0001) with respect to Japanese Orthopaedic Association (JOA) scores. In addition, the total effective rate in five individual trials was greater for acupuncture than for mannitol plus dexamethasone and mecobalamin, ibuprofen plus fugui gutong capsule, loxoprofen, mannitol plus dexamethasone and huoxue zhitong decoction, respectively. Additionally, two individual trials showed a superior effect of acupuncture in VAS scores comparedwith ibuprofen or mannitol plus dexamethasone, respectively.

Conclusions

Acupuncture showed a more favourable effect in the treatment of LDH than lumbar traction, ibuprofen, diclofenac sodium, meloxicam, mannitol plus dexamethasone and mecobalamin, fugui gutong capsule plus ibuprofen, mannitol plus dexamethasone, loxoprofen and huoxue zhitong decoction. However, further rigorously designed, large-scale RCTs are needed to confirm these findings.

Acupuncture for neuropathic pain in adults

BACKGROUND

Neuropathic pain may be caused by nerve damage, and is often followed by changes to the central nervous system. Uncertainty remains regarding the effectiveness and safety of acupuncture treatments for neuropathic pain, despite a number of clinical trials being undertaken.

OBJECTIVES

To assess the analgesic efficacy and adverse events of acupuncture treatments for chronic neuropathic pain in adults.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, four Chinese databases, ClinicalTrials.gov and World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) on 14 February 2017. We also cross checked the reference lists of included studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) with treatment duration of eight weeks or longer comparing acupuncture (either given alone or in combination with other therapies) with sham acupuncture, other active therapies, or treatment as usual, for neuropathic pain in adults. We searched for studies of acupuncture based on needle insertion and stimulation of somatic tissues for therapeutic purposes, and we excluded other methods of stimulating acupuncture points without needle insertion. We searched for studies of manual acupuncture, electroacupuncture or other acupuncture techniques used in clinical practice (such as warm needling, fire needling, etc).

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane. The primary outcomes were pain intensity and pain relief. The secondary outcomes were any pain-related outcome indicating some improvement, withdrawals, participants experiencing any adverse event, serious adverse events and quality of life. For dichotomous outcomes, we calculated risk ratio (RR) with 95% confidence intervals (CI), and for continuous outcomes we calculated the mean difference (MD) with 95% CI. We also calculated number needed to treat for an additional beneficial outcome (NNTB) where possible. We combined all data using a random-effects model and assessed the quality of evidence using GRADE to generate 'Summary of findings' tables.

MAIN RESULTS

We included six studies involving 462 participants with chronic peripheral neuropathic pain (442 completers (251 male), mean ages 52 to 63 years). The included studies recruited 403 participants from China and 59 from the UK. Most studies included a small sample size (fewer than 50 participants per treatment arm) and all studies were at high risk of bias for blinding of participants and personnel. Most studies had unclear risk of bias for sequence generation (four out of six studies), allocation concealment (five out of six) and selective reporting (all included studies). All studies investigated manual acupuncture, and we did not identify any study comparing acupuncture with treatment as usual, nor any study investigating other acupuncture techniques (such as electroacupuncture, warm needling, fire needling).One study compared acupuncture with sham acupuncture. We are uncertain if there is any difference between the two interventions on reducing pain intensity (n = 45; MD -0.4, 95% CI -1.83 to 1.03, very low-quality evidence), and neither group achieved 'no worse than mild pain' (visual analogue scale (VAS, 0-10) average score was 5.8 and 6.2 respectively in the acupuncture and sham acupuncture groups, where 0 = no pain). There was limited data on quality of life, which showed no clear difference between groups. Evidence was not available on pain relief, adverse events or other pre-defined secondary outcomes for this comparison.Three studies compared acupuncture alone versus other therapies (mecobalamin combined with nimodipine, and inositol). Acupuncture may reduce the risk of 'no clinical response' to pain than other therapies (n = 209; RR 0.25, 95% CI 0.12 to 0.51), however, evidence was not available for pain intensity, pain relief, adverse events or any of the other secondary outcomes.Two studies compared acupuncture combined with other active therapies (mecobalamin, and Xiaoke bitong capsule) versus other active therapies used alone. We found that the acupuncture combination group had a lower VAS score for pain intensity (n = 104; MD -1.02, 95% CI -1.09 to -0.95) and improved quality of life (n = 104; MD -2.19, 95% CI -2.39 to -1.99), than those receiving other therapy alone. However, the average VAS score of the acupuncture and control groups was 3.23 and 4.25 respectively, indicating neither group achieved 'no worse than mild pain'. Furthermore, this evidence was from a single study with high risk of bias and a very small sample size. There was no evidence on pain relief and we identified no clear differences between groups on other parameters, including 'no clinical response' to pain and withdrawals. There was no evidence on adverse events.The overall quality of evidence is very low due to study limitations (high risk of performance, detection, and attrition bias, and high risk of bias confounded by small study size) or imprecision. We have limited confidence in the effect estimate and the true effect is likely to be substantially different from the estimated effect.

AUTHORS' CONCLUSIONS

Due to the limited data available, there is insufficient evidence to support or refute the use of acupuncture for neuropathic pain in general, or for any specific neuropathic pain condition when compared with sham acupuncture or other active therapies. Five studies are still ongoing and seven studies are awaiting classification due to the unclear treatment duration, and the results of these studies may influence the current findings.

Acupoint herbal patching for allergic rhinitis: a systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Acupoint herbal patching (AHP) is extensively used in treatment of allergic rhinitis in China. However, existing systematic review is insufficient.

OBJECTIVE OF REVIEW

To evaluate the effectiveness and safety of AHP in treating allergic rhinitis.

SEARCH STRATEGY

We searched seven electronic databases for randomised controlled trials (RCTs) from inception until August 2014.

EVALUATION METHOD

Two authors selected studies, extracted data and evaluated risk of bias independently. The Cochrane risk of bias tool was applied to assess the methodological quality of the included trials, and RevMan 5.2 software was utilised to perform data analysis.

RESULTS

Twenty RCTs involving 2438 participants were included. Most of them were evaluated as high risk of bias. Acupoint herbal patching significantly decreased the recurrence rate at 6 months compared with Western medicine (RR 0.52; 95% CI 0.42-0.64), and similar effect was found for AHP plus Western medicine versus Western medicine (RR 0.53; 95% CI 0.44-0.65). Acupoint herbal patching appeared to be more effective than placebo in improving total clinical symptoms and signs after treatment and at 6 months, and in improving quality of life at <3 months and over 3 months. No severe adverse effects were found in the AHP groups.

CONCLUSIONS

Acupoint herbal patching alone or combined with Western medicine appears to be more effective than placebo or Western medicine, respectively. Acupoint herbal patching seems to be a safe treatment. However, the findings should be interpreted with caution. Further large-scale, rigorously designed trials are warranted to confirm the findings.

[Revised STandards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA): extending the CONSORT statement (Chinese version)]

The STandards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) were published in five journals in 2001 and 2002. These guidelines, in the form of a checklist and explanations for use by authors and journal editors, were designed to improve reporting of acupuncture trials, particularly the interventions, thereby facilitating their interpretation and replication. Subsequent reviews of the application and impact of STRICTA have highlighted the value of STRICTA as well as scope for improvements and revision. To manage the revision process a collaboration between the STRICTA Group, the CONSORT Group and the Chinese Cochrane Centre was developed in 2008. An expert panel with 47 participants was convened that provided electronic feedback on a revised draft of the checklist. At a subsequent face-to-face meeting in Freiburg, a group of 21 participants further revised the STRICTA checklist and planned dissemination. The new STRICTA checklist, which is an official extension of CONSORT, includes 6 items and 17 subitems. These set out reporting guidelines for the acupuncture rationale, the details of needling, the treatment regimen, other components of treatment, the practitioner background and the control or comparator interventions. In addition, and as part of this revision process, the explanations for each item have been elaborated, and examples of good reporting for each item are provided. In addition, the word "controlled" in STRICTA is replaced by "clinical", to indicate that STRICTA is applicable to a broad range of clinical evaluation designs, including uncontrolled outcome studies and case reports. It is intended that the revised STRICTA checklist, in conjunction with both the main CONSORT statement and extension for non-pharmacological treatment, will raise the quality of reporting of clinical trials of acupuncture.

Impact evaluation of CONSORT and STRICTA guidelines on reporting quality for randomized controlled trials of acupuncture conducted in China

OBJECTIVE

To evaluate and compare the reports' qualities of acupuncture randomized controlled trials (RCTs) conducted in China before and after the implementation of two guidelines, i.e., the Consolidated Standards of Reporting Trials (CONSORT) statement and the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA).

METHODS

Proportions of studies that reported CONSORT and STRICTA items were compared for the years before and after implementation of these two guidelines. In addition, the total score of each item's reporting were calculated and reported differences during different date ranges were compared.

RESULTS

For CONSORT items (maximum score 8), there was evidence of a slight improvement in reporting between 1994-1995 and 1999-2000 combined (2.5±0.6) and 2004-2005 and 2009-2010 combined (3.0±0.9; difference 0.4, 95% confidence interval, 0.3 to 0.6, P<0.01). For STRICTA items (maximum score 17), there was evidence that a slight improvement in reporting between 1994-1995 and 1999-2000 combined (8.6±2.1) and 2004-2005 and 2009-2010 combined (10.1±1.8; difference 1.5, 95% confidence interval, 1.1 to 1.9, P<0.01).

CONCLUSION

Quality of reporting for RCTs of acupuncture treatment conducted in China have generally improved since the introduction of the STRICTA and CONSORT guidelines.

Integrative treatment for low back pain: An exploratory systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Low back pain (LBP) is a common musculoskeletal condition often treated using integrative medicine (IM). Most reviews have focused on a single complementary and alternative medicine (CAM) therapy for LBP rather than evaluating wider integrative approaches. This exploratory systematic review aimed to identify randomized controlled trials (RCTs) and provide evidence on the effectiveness, cost effectiveness and adverse effects of integrative treatment for LBP.

METHODS

A literature search was conducted in 12 English and Chinese databases. RCTs evaluating an integrative treatment for musculoskeletal related LBP were included. Reporting, methodological quality and relevant clinical characteristics were assessed and appraised. Metaanalyses were performed for outcomes where trials were sufficiently homogenous.

RESULTS

Fifty-six RCTs were identified evaluating integrative treatment for LBP. Although reporting and methodological qualities were poor, meta-analysis showed a favourable effect for integrative treatment over conventional and CAM treatment for back pain and function at 3 months or less follow-up. Two trials investigated costs, reporting £ 5332 per quality adjusted life years with 6 Alexander technique lessons plus exercise at 12 months follow-up; and an increased total costs of $244 when giving an additional up to 15 sessions of CAM package of care at 12 weeks. Sixteen trials mentioned safety; no severe adverse effects were reported.

CONCLUSION

Integrative treatment that combines CAM with conventional therapies appeared to have beneficial effects on pain and function. However, evidence is limited due to heterogeneity, the relatively small numbers available for subgroup analyses and the low methodological quality of the included trials. Identification of studies of true IM was not possible due to lack of reporting of the intervention details (registration No. CRD42013003916).

A Systematic Review of Reporting Tools Applicable to Sexual and Reproductive Health Programmes: Step 1 in Developing Programme Reporting Standards

BACKGROUND

Complete and accurate reporting of programme preparation, implementation and evaluation processes in the field of sexual and reproductive health (SRH) is essential to understand the impact of SRH programmes, as well as to guide their replication and scale-up.

OBJECTIVES

To provide an overview of existing reporting tools and identify core items used in programme reporting with a focus on programme preparation, implementation and evaluation processes.

METHODS

A systematic review was completed for the period 2000-2014. Reporting guidelines, checklists and tools, irrespective of study design, applicable for reporting on programmes targeting SRH outcomes, were included. Two independent reviewers screened the title and abstract of all records. Full texts were assessed in duplicate, followed by data extraction on the focus, content area, year of publication, validation and description of reporting items. Data was synthesized using an iterative thematic approach, where items related to programme preparation, implementation and evaluation in each tool were extracted and aggregated into a consolidated list.

RESULTS

Out of the 3,656 records screened for title and abstracts, full texts were retrieved for 182 articles, out of which 108 were excluded. Seventy-four full text articles corresponding to 45 reporting tools were retained for synthesis. The majority of tools were developed for reporting on intervention research (n = 15), randomized controlled trials (n = 8) and systematic reviews (n = 7). We identified a total of 50 reporting items, across three main domains and corresponding sub-domains: programme preparation (objective/focus, design, piloting); programme implementation (content, timing/duration/location, providers/staff, participants, delivery, implementation outcomes), and programme evaluation (process evaluation, implementation barriers/facilitators, outcome/impact evaluation).

CONCLUSIONS

Over the past decade a wide range of tools have been developed to improve the reporting of health research. Development of Programme Reporting Standards (PRS) for SRH can fill a significant gap in existing reporting tools. This systematic review is the first step in the development of such standards. In the next steps, we will draft a preliminary version of the PRS based on the aggregate list of identified items, and finalize the tool using a consensus process among experts and user-testing.

Effects of transcutaneous electrical acupoint stimulation at different frequencies on perioperative anesthetic dosage, recovery, complications, and prognosis in video-assisted thoracic surgical lobectomy: a randomized, double-blinded, placebo-controlled trial

BACKGROUND

Transcutaneous electrical acupoint stimulation (TEAS), a non-invasive and non-pharmacological adjunctive intervention for perioperative analgesia, may also reduce the incidence of postoperative pulmonary complications. The effect of TEAS on video-assisted thoracic surgical (VATS) patients is still unknown, however. The purpose of this study was to investigate the effects of TEAS of different frequency on perioperative anesthetic dosage, recovery, complications, and prognosis for patients undergoing VATS lobectomy.

METHODS

Eighty VATS lobectomy patients with no previous experience of TEAS or acupuncture were randomly assigned to four groups: control (con), 2/100, 2, and 100 Hz. The last three experimental groups received TEAS at the indicated frequencies for 30 min before induction, during the operation, and for another 30 min 24 and 48 h after surgery. 2/100 Hz is a type of alternating frequency which goes between 2 and 100 Hz every 3 s. TEAS was administered over acupoints Neiguan, Hegu, Lieque, and Quchi on the sick lateral. Electrodes were applied to the patients in the control group, but no TEAS was used. Anesthetic dosage, blood gas analysis results, lung function indexes FEV₁ and FVC, post-anesthesia care unit (PACU) status, postoperative complications, and quality of life scores were recorded and analyzed statistically.

RESULTS

Intraoperative opioid consumption was lowest in the 2/100 Hz group, with statistical significance (con, P ≤ 0.001; 2 Hz, P ≤ 0.001; 100 Hz, P = 0.026). Compared with preoperative FEV₁ and FVC, postoperative FEV₁ and FVC were significantly lower in all groups; during one-lung ventilation, arterial oxygen partial pressure (PaO₂) decreased more slowly in the 2/100 Hz group than in the con group (P = 0.042). Moreover, in the 2/100 Hz group extubation time was shorter (P = 0.038), visual analgesia scale score lower (P = 0.047), and duration of PACU stay shorter (P = 0.043) than in the con group. In the 100 Hz group incidence of postoperative nausea and vomiting (PONV) was lower than the con group (P = 0.044). In all groups mean postoperative physical component scores were significantly lower than mean preoperative scores.

CONCLUSIONS

TEAS is a safe noninvasive adjunctive intervention for anesthesia management among patients undergoing VATS lobectomy. TEAS at 2/100 Hz can reduce intraoperative opioid dosage and slow the decrease of PaO₂ during one-lung ventilation. It can also effectively reduce pain score, extubation time, and PACU stay immediately after surgery. Further, 100 Hz TEAS can reduce PONV morbidity.

Auricular Acupressure Can Modulate Pain Threshold

The objective of our study was to investigate if auriculotherapy (AT) can modulate pain threshold. In our experiments, AT consisted of placing Vaccaria seeds over the “fingers point” of one ear. Two groups of healthy volunteers were enrolled for the study. Each subject was asked to perform an autoalgometric test developed by our group on three occasions: before, 1 hour after, AT and 24 hours after AT. Participants of the first group received a 2-minute long session of AT, while participants of the second group received a 2-minute long session of sham treatment, consisting of a puncture/massage above the skin of the neck. The autoalgometric test consisted of applying an increasing pressure with the finger-tips and finger-backs of four fingers by the subjects themselves (i.e., eight sites were evaluated) against a round-shaped needle for two times: until a minimum pain sensation (first time, minimal test) or a maximally tolerable pain sensation (second time, maximal test). Our results showed a significant higher pain threshold in the maximal test at 24 hours after AT compared to sham treatment. This result indicates for the first time that AT can increase pain tolerability, rather than affecting the minimal pain threshold.

STRICTA: is it time to do more?

Background

In order to facilitate the completeness and transparency of reporting on randomized controlled trials undertaken using acupuncture interventions, a consensus group of international experts developed the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA) in 2002. This reporting guideline was updated in 2010, and was applicable to a broader range of acupuncture research, including uncontrolled trials and case reports. Subsequent evaluations have noted limitations on the impact of STRICTA in the reporting quality of acupuncture trials, and the description of acupuncture details remains poor. Thus improvement in the efficacy of the STRICTA guidelines is called for.

Discussion

We explored the STRICTA guidelines from four aspects, including the development procedure, validity assessment, endorsement and adherence, and citation situation. Based upon these findings, we provided five potential suggestions for further development of STRICTA.

Summary

STRICTA are valid reporting guidelines based on robust methodology and scientific content. However specific implementation strategies including: updating the STRICTA checklist; improving the STRICTA reporting efficiency; consistency with implementing the “Instructions for authors” for journals; establishing global STRICTA research centers; and expanding the STRICTA website, are needed. Such strategies will improve their utilization and impact positively on the quality of reporting on acupuncture research outcomes.
