RESUMO
This study systematically searched and sorted out randomized controlled trial(RCT) of acupuncture-moxibustion treatment for non-specific low back pain by scoping review, so as to demonstrate the current state of the research evidence and provide a reference point for future clinical research and healthcare decision-making. Eight commonly used Chinese and English databases were searched, and the search time was from the establishment of the databases to July 7, 2023, so as to analyze the characteristics of the current status of the current research through visualization methods. A total of 50 studies were included, including 23 studies in Chinese and 27 studies in English. The overall number of studies showed an increasing trend. The percentage of studies published in Chinese non-core journals was 42.0%. The disease subtypes of interest were mainly chronic non-specific low back pain, accounting for 68.0% of the studies. The sample sizes of the studies were mainly concentrated in the range of 50-100 cases. A total of 15 types of interventions were categorized, with acupuncture interventions being the most studied. Duration of treatment did not exceed one month in 80.0% of the studies. Only 8.0% of the studies used minimal clinical important difference(MCID) as a basis for judgment. The follow-up period was set within 3 months in 28.0% of the studies, and 82.0% of the studies concluded that acupuncture-moxibustion was effective in the treatment of non-specific lower back pain. Adverse events were reported in 20.0% of the studies. The risk of bias in the included studies was dominated by low risk of bias and uncertain risk of bias, with fewer studies focusing on high risks of bias. In most of the studies, acupuncture-moxibustion was significantly more effective than the control group. The research on acupuncture-moxibustion treatment for non-specific low back pain is developing rapidly, but there are still insufficient studies on psychological state, safety, and other indicators, and there are still some studies with uncertain risks of bias, which is not conducive to the generalization and application of the findings. Therefore, future studies should improve and refine these shortcomings.

To systematically evaluate the clinical efficacy and safety of Ginkgo Leaf Tablets(GLT) in the treatment of acute cerebral infarction(ACI). Seven databases both at home and abroad were systematically retrieved from their establishment to March 2020. The data of the included studies were extracted after review and screening. The quality of the included studies was assessed with the Cochrane risk bias assessment tool, and then the included studies were put into Meta-analysis by RevMan 5.3 to evaluate the total cli-nical efficiency, neurological function score, blood lipids and incidence of adverse reactions in treatment of ACI by GLT. Finally, the GRADE system was adopted to evaluate the evidence quality of each outcome indicator and form recommendations. Ten studies involving 886 participants were included, all of which were of low quality. Meta-analysis results showed that,(1)in terms of the total clinical efficiency, GLT+Western medicine was superior to Western medicine alone(RR_(NDS)=1.20, 95%CI[1.06, 1.36], P=0.005; RR_(NIHSS)=1.35, 95%CI[1.09, 1.69], P=0.007), and there was no statistical difference between GLT+Xuesaitong Injection+Wes-tern medicine and Xuesaitong Injection+Western medicine(RR=1.16, 95%CI[1.00, 1.35], P=0.05).(2)In terms of improving neurological function score, GLT+Western medicine was superior to Western medicine alone(MD_(NIHSS[moderate(severe)])=-1.55, 95%CI[-2.22,-0.88], P<0.000 01; MD_(NIHSS(severe))=-7.51, 95%CI[-8.00,-7.02], P<0.000 01; MD_(NDS)=-1.36, 95%CI[-2.39,-0.33], P=0.01), and GLT+Danshen Injection+Western medicine was superior to Danshen Injection+Western medicine(MD_(NDS)=-3.09, 95%CI[-3.84,-2.34], P<0.000 01).(3)In terms of regulating blood lipids, GLT+Western medicine was superior to Wes-tern medicine alone(MD_(TC)=-1.40, 95%CI[-2.13,-0.66], P=0.000 2; MD_(TG)=-1.29, 95%CI[-1.86,-0.73], P<0.000 01; MD_(LDL-C)=-1.48, 95%CI[-2.91,-0.04], P=0.04; MD_(HDL-C)=0.07, 95%CI[0.02, 0.12], P=0.009).(4)In terms of incidence of adverse reactions, there was no statistical difference between GLT+Western medicine and Western medicine alone(RR=0.63, 95%CI[0.30, 1.32], P=0.22). The results of the evaluation showed that the evidence level of each outcome indicator was low, and the recommendation was at weak level. In conclusion, GLT+Western medicine could improve the total clinical efficiency, neurological function score, and blood lipid status, with a low incidence of adverse reactions. However, due to the small amount of included stu-dies, low study quality and low level of evidence, it is expected to carry out clinical studies with standardized design and large sample size in the future to further investigate the clinical efficacy and safety of GLT in the treatment of ACI.

INTRODUCTION: Acupuncture and related acupoint therapies have been widely used for smoking cessation. Some relevant systematic reviews (SRs) have been published. There is a need to summarize and update the evidence to inform practice and decision-making. METHODS: Eight databases were searched from their inception to December 2023. SRs, any randomized controlled trials (RCTs) comparing acupuncture therapies with sham acupuncture, pharmacotherapy, behavioral therapy, or no treatment, were included. The primary outcome was the abstinence rate. AMSTAR-2 was employed to assess the quality of SRs. An updated meta-analysis was conducted based on SRs and RCTs. Data were synthesized using risk ratios (RR) with 95% confidence intervals (CIs). The GRADE approach was employed to assess the certainty of the updated evidence. RESULTS: Thirteen SRs and 20 RCTs outside of the SRs were identified. The SRs were of low or very low quality by AMSTAR-2. Sixteen (80%) RCTs were at high risk of performance bias. Eight acupuncture and related acupoint therapies were involved. The short-term (≤6 months) abstinence rate outcome was summarized as follows. Most SRs suggested that filiform needle acupuncture or acupressure had a better effect than sham acupuncture, but the findings were inconsistent. The updated meta-analysis also suggested that filiform needle acupuncture was more effective than sham acupuncture (RR=1.44; 95% CI: 1.02-2.02; I2 = 66%; low certainty; 9 RCTs, n=1358). Filiform needle acupuncture combined with acupressure was comparable to nicotine patches (RR=0.99; 95% CI: 0.74-1.32; low certainty; 6 RCTs, n= 524). Acupressure was superior to counseling (RR=1.46; 95% CI: 1.14-1.87; I2=5%; low certainty; 8 RCTs, n=595). No serious adverse events were reported in these SRs or RCTs. CONCLUSIONS: Low certainty evidence suggests that filiform needle acupuncture and auricular acupressure appear to be safe and effective in achieving short-term smoking cessation. However, long-term follow-up data are needed.
RESUMO
Background: Intrahepatic cholangiocarcinoma (iCCA) is the second most common primary liver cancer. While multiple risk factors for iCCA have been established, metabolic diseases (obesity, diabetes, NAFLD, dyslipidemia, and hypertension) and other risk factors, including smoking and drinking, are still controversial due to their potential confounders. Here, Mendelian randomization (MR) analysis was performed to identify the causal relationship between them. Method: In this study, we obtained GWAS data related to exposures from corresponding large genome-wide association studies. Summary-level statistical data for iCCA were obtained from the UK Biobank (UKB). We performed a univariable MR analysis to identify whether genetic evidence of exposure was significantly associated with iCCA risk. A multivariable MR analysis was conducted to estimate the independent effects of exposures on iCCA. Results: Univariable and multivariable MR analysis based on the large GWAS data indicated that there is little evidence to support the genetic role of metabolic factors, smoking, drinking, and NAFLD in iCCA development (P >0.05). In contrast to most current studies, their impact on iCCA development, if any, might be smaller than we thought. The previous positive results might be due to the comorbidities between diseases and potentially unavoidable confounding factors. Conclusion: In this MR study, we found no strong evidence to support causal associations between metabolic factors, NAFLD, smoking, drinking, and iCCA risk.
RESUMO
OBJECTIVE: To summarize and identify the available instruments/methods assessing the adequacy of acupuncture in randomized controlled trials (RCTs) for proposing a new improved instrument. METHODS: A systematic literature search was carried out in 7 electronic databases from inception until 21st November 2022. Any study evaluating the adequacy or quality of acupuncture, specifying specific acupuncture treatment-related factors as criteria of subgroup analysis, or developing an instrument/tool to assess the adequacy or quality of acupuncture in an RCT was included. Basic information, characteristics and contents of acupuncture adequacy assessment were presented as frequencies and percentages. RESULTS: Forty studies were included in this systematic review. Thirty-five studies (87.50%) were systematic reviews, none of which used formal methods to develop the assessment instruments/methods of acupuncture adequacy; of 5 methodological studies, only 1 study used a relatively formal method. Thirty-two studies (82.05%) assessed the components of acupuncture, while 7 (17.95%) assessed the overall quality of acupuncture. An independent assessment instrument/method was used to assess acupuncture adequacy in 29 studies (74.35%), whereas as one part of a methodological quality assessment scale in 10 (25.65%). Only 9 (23.00%) studies used the assessment results for subgroup analysis, sensitivity analysis or the criteria for inclusion in the meta-analysis. CONCLUSION: Assessment contents for adequacy or quality of acupuncture in RCTs hadn't still reached consensus and no widely used assessment tools appeared. The methodology of available assessment instruments/scales is far from formal and rigorous. A new instrument/tool assessing adequacy of acupuncture should be developed using a formal method.

OBJECTIVES: To evaluate the report quality, methodological quality and evidence quality of the systematic reviews and meta-analyses (SRs/MAs) of acupuncture for in vitro fertilization-embryo transfer (IVF-ET). METHODS: The SRs/MAs of acupuncture for IVF-ET were searched electronically from databases of CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, Cochrane Library, from inception of each database to September 27th, 2022. Two reviewers independently screened the literature and extracted the data. Using PRISMA statement, the AMSTAR 2 scale and the GRADE system, the report quality, methodological quality and evidence quality of the included SRs/MAs were assessed. RESULTS: A total of 28 SRs/MAs were included, with PRISMA scores ranging from 8.5 points to 27 points. The problems of report quality focused on protocol and registration, retrieval, risk of bias in studies, additional analysis, limitations and funding. The methodological quality of included studies was generally low, reflecting on items 2, 3, 7, 10, 12 and 16. A total of 85 outcome indexes were included in the GRADE system for evidence grade evaluation. Most of the evidences were low or very low in quality. The reasons for the downgrade were related to study limitations, inconsistency, imprecision and publication bias. CONCLUSIONS: Acupuncture therapy improves the outcomes of IVF-ET, but the methodological quality and evidence quality of related SRs/MAs are low. It is recommended to conduct more high-quality studies in the future to provide more reliable evidences.

OBJECTIVE: To assess the use of evidence-based research (EBR) approach in randomized controlled trials (RCTs) of acupuncture-related therapies for primary dysmenorrhea (PD). METHODS: PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Database, and China Science and Technology Journal Database were searched from January 2013 to December 2022 for RCTs of acupuncture on PD. The full text and references of each RCT were read to assess whether systematic reviews (SRs) or other types of studies with similar research questions and end-users' perspectives were cited to justify and design the trial. In addition, the discussion section were analyzed to evaluate whether trials placed the new result in the existing SRs to draw a conclusion. Multivariable logistic regression was used to find variables that associated with 3 aspects of EBR approach: (1) citing clinical studies for justification, (2) citing relevant studies that obtain the perspectives of end users, and (3) citing clinical studies for results discussion. RESULTS: Of 473 RCTs included, 45.67% (216) of the trials cited relevant similar studies, 21.56% (102) referenced to the studies that collected end-users' perspectives, and 10.99% (52) placed result in the context of the previous research. Few RCTs appropriately applied EBR approach. Among all the included studies, 3.17% (15) of the trials used SRs to inform study questions but none of them used updated SRs with acceptable quality; 1.05% (5) of the trials cited SRs of end-user's perspectives in the justification and design of the study, and only 1 trial added results in existing SR to draw a conclusion. Year of publication, language, funding, registration, ethical approval and number of sites were significantly associated with 1 of the 3 aspects of EBR approach. CONCLUSIONS: Few RCTs in acupuncture-related therapies for PD used the EBR approach to minimize research redundancy. Researchers, research institutes, funding agencies, ethics committees, journals and peer reviewers in acupuncture should make efforts to use and promote the EBR approach to ensure the value of new trials.
RESUMO
As an indicator that measures the degree of implementation of intervention measures during the implementation process, fidelity could be used for monitoring and quality evaluation of the completion degree of intervention measures, and plays an important role in improving the degree of intervention implementation and clarifying the factors that affect intervention implementation. This article aims to introduce the connotation and significance, measurement, control, and current application status of fidelity, as well as the current application status of fidelity in acupuncture-moxibustion clinical research and its inspiration for future research. Meanwhile, based on the existing evaluation tool development methods of fidelity and the characteristics of acupuncture-moxibustion clinical research, a preliminary fidelity evaluation framework is proposed. Introducing fidelity into acupuncture-moxibustion clinical research could improve the implementation quality and compliance of acupuncture-moxibustion in clinical research, increase the credibility and effectiveness of clinical research results, and promote the transformation of acupuncture-moxibustion experience into easily learnable and promotable treatment plans.

Background: Xingnaojing injection (XNJ) is the only Chinese herbal injection approved for both intracerebral hemorrhage and ischemic stroke (IS) first-aid on ambulances in China; many systematic reviews (SRs) and meta-analyses (MAs) of XNJ on stroke have been published. The purpose of this research was to evaluate and summarize the current evidence on XNJ for IS. Methods: A comprehensive search was conducted for SRs and MAs of XNJ on IS in seven databases up to January 1, 2021. Two authors independently identified SRs and MAs, extracted data, assessed the quality of the included SRs and MAs using the Assessment of Multiple Systematic Reviews 2 (AMSTAR 2), and assessed quality of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE). Results: A total of 10 SRs met the inclusion criteria. The quality of included SRs using AMSTAR 2 was critically low as the critical items were poorly reported. Only 10% of SRs reported 50% of the 16 items, while the remaining 90% SRs reported just less than half of the items on AMSTAR 2. For GRADE, 7 (35%) of outcomes had low-quality evidence, 10 (50%) with very low, and 3 (15%) with moderate quality evidence. Very low to low quality of evidence indicated XNJ plus conventional therapy (CT) alleviated the neurological deficits of acute IS. Moderate-quality evidence showed XNJ plus CT reduced mortality when compared to Danshen injection plus CT, and very low-quality evidence showed XNJ plus CT could not improve the degree of coma, while low-quality evidence indicated the opposite. Mild adverse events in the CT group were less than those in the XNJ plus CT group, and there were no serious adverse events, but there was no statistical difference between the two groups. The included 10 SRs indicated that XNJ was used for acute IS, but only four SRs (40%) reported the course of disease. Conclusion: XNJ appears to be effective and safe for acute IS in improving the neurological deficits, but the evidence is not robust enough. However, whether administering XNJ immediately after or within 24 h of IS is best remains unknown due to the lack of data. Well-designed large-scale randomized controlled trials with measurable outcomes are required in future studies.
RESUMO
Objective: To present the evidence of the therapeutic effects and safety of Chinese herbal medicine (CHM) used with or without conventional western therapy for COVID-19. Methods: Clinical studies on the therapeutic effects and safety of CHM for COVID-19 were included. We summarized the general characteristics of included studies, evaluated methodological quality of randomized controlled trials (RCTs) using the Cochrane risk of bias tool, analyzed the use of CHM, used Revman 5.4 software to present the risk ratio (RR) or mean difference (MD) and their 95% confidence interval (CI) to estimate the therapeutic effects and safety of CHM. Results: A total of 58 clinical studies were identified including RCTs (17.24%, 10), non-randomized controlled trials (1.72%, 1), retrospective studies with a control group (18.97%, 11), case-series (20.69%, 12) and case-reports (41.38%, 24). No RCTs of high methodological quality were identified. The most frequently tested oral Chinese patent medicine, Chinese herbal medicine injection or prescribed herbal decoction were: Lianhua Qingwen granule/capsule, Xuebijing injection and Maxing Shigan Tang. In terms of aggravation rate, pooled analyses showed that there were statistical differences between the intervention group and the comparator group (RR 0.42, 95% CI 0.21 to 0.82, six RCTs; RR 0.38, 95% CI 0.23 to 0.64, five retrospective studies with a control group), that is, CHM plus conventional western therapy appeared better than conventional western therapy alone in reducing aggravation rate. In addition, compared with conventional western therapy, CHM plus conventional western therapy had potential advantages in increasing the recovery rate and shortening the duration of fever, cough and fatigue, improving the negative conversion rate of nucleic acid test, and increasing the improvement rate of chest CT manifestations and shortening the time from receiving the treatment to the beginning of chest CT manifestations improvement. For adverse events, pooled data showed that there were no statistical differences between the CHM and the control groups. Conclusion: Current low certainty evidence suggests that there maybe a tendency that CHM plus conventional western therapy is superior to conventional western therapy alone. The use of CHM did not increase the risk of adverse events.
RESUMO
BACKGROUND: The World Health Organization characterized the Coronavirus disease 2019 (COVID-19) as a pandemic on March 11th. Many clinical trials on COVID-19 have been registered, and we aim to review the study characteristics and provide guidance for future trials to avoid duplicated effort. METHODS: Studies on COVID-19 registered before March 3rd, 2020 on eight registry platforms worldwide were searched and the data of design, participants, interventions, and outcomes were extracted and analyzed. RESULTS: Three hundred and ninety-three studies were identified and 380 (96.7%) were from mainland China, while 3 in Japan, 3 in France, 2 in the US, and 3 were international collaborative studies. Two hundred and sixty-six (67.7%) aimed at therapeutic effect, others were for prevention, diagnosis, prognosis, etc. Two hundred and two studies (51.4%) were randomized controlled trials. Two third of therapeutic studies tested Western medicines including antiviral drugs (17.7%), stem cell and cord blood therapy (10.2%), chloroquine and derivatives (8.3%), 16 (6.0%) on Chinese medicines, and 73 (27.4%) on integrated therapy of Western and Chinese medicines. Thirty-one studies among 266 therapeutic studies (11.7%) used mortality as primary outcome, while the most designed secondary outcomes were symptoms and signs (47.0%). Half of the studies (45.5%) had not started recruiting till March 3rd. CONCLUSION: Inappropriate outcome setting, delayed recruitment and insufficient numbers of new cases in China implied many studies may fail to complete. Strategies and protocols of the studies with robust and rapid data sharing are warranted for emergency public health events, helping the timely evidence-based decision-making.
RESUMO
OBJECTIVE: To observe the therapeutic effect of acupuncture in the treatment of patients with knee osteoarthritis (KOA) in the early stage. METHODS: A total of 60 KOA patients were randomized into medication group and acupuncture combined with medication (acupuncture) group (nï¼ 30 in each group). Patients of the medication group were treated by external application of Diclofenac Diethylamine Emulgel around the affected joint, 3 times a day for 2 successive weeks and reasonable exercising training. Patients of the acupuncture group received routine medication and reasonable exercising training and acupuncture of Ashi-points, Zusanli (ST36), Yanglingquan (GB34), Yinlingquan (SP9), Neixiyan (EX-LE4) and Dubi (ST35) at affected side with filiform needles which were manipulated with uniform reinforcing-reducing method for a while, followed by retaining the needles for 30 min. The treatment was conducted once every other day for 2 weeks. The pain degree was assessed by using visual analog scale (VAS) and the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) scale (0ï¼240 points) was used to evaluate the severity of KOA, and the "Diagnosis of Syndromes of Traditional Chinese Medicine" was used to assess the therapeutic effect after the treatment. RESULTS: After the treatment, the VAS and WOMAC scores of both medication and acupuncture groups were significantly and respectively decreased in comparison with their own pre-treatment (P<0.05), and the scores of the two indexes of the acupuncture group were evidently lower than those of the medication group (P<0.05). Of the two 30 cases in the medication and acupuncture groups, 5 (16.67%) and 6 (20.00%) were cured, 17 (56.67%) and 19 (63.33%) experienced marked improvement, 6 (20.00%) and 4 (13.33%) were effective, 2 (6.67%) and 1 (3.33%) were ineffective, with the effective rate of cure plus marked effectiveness being 73.33% and 83.33%, respectively. No significant difference was found between the two groups in the therapeutic effect (P>0.05). CONCLUSION: Acupuncture combined with medication has a better therapeutic effect in the treatment of KOA in the early stage than that of the simple medication.

OBJECTIVE: To observe the effect of acupuncture of intraorbital and extraorbital acupoints on apoptosis and expression of Bax, Bcl-2 and Caspase-3 proteins of retinal ganglion tissue in rabbits with nonarteritis anterior ischemic optic neuropathy (NAION), so as to reveal its mechanism underlying improvement of NAION. METHODS: Female New Zealand rabbits were randomly divided into four groups: model, intraocular needling (ION), extraocular needling (EON), IONï¼EON groups (nï¼5 per group), and the 5 healthy eyes of those rabbits in the model group were selected to be used as the control group. The NAION model of the right eye was established by photodynamic stroke method. For ION group, acupoints "Jingming" (BL1), "Chengqi" (ST1) and "Qiuhou" (EX-HN7) were needled, and for EON group, "Cuanzhu" (BL2), "Yuyao" (EX-HN4) and "Qiaoming" (EX) were needled with filiform needles, followed by retaining the needles for 30 min. For IONï¼EON group, the 6 acupoints were needled simutaneously. The treatment was conducted once daily for 3 days. The apoptosis of retinal ganglion tissue was detected by using TUNEL fluorescence labeling, and the expression of Bax, Bcl-2 and active Caspase-3 in the retinal ganglion were detected by immunohistochemistry. RESULTS: Following modeling and compared with the control group, the number of the apoptotic cells, and the expression levels of Bax and Caspase-3 proteins, as well as the ratio of Bax/Bcl-2 were significantly increased in the model group (P<0.01), while the expression of Bcl-2 was significantly decreased (P<0.01). After intervention, the number of the apoptotic cells in the ION, EON and IONï¼EON groups, and the ratio of Bax/Bcl-2 in EON and IONï¼EON groups, and the expression of Caspase-3 proteins in the ION and IONï¼EON groups were significantly down-regulated (P<0.01, P<0.05), and the expression levels of Bcl-2 in both EON and IONï¼EON groups were significantly up-regulated in comparison with the model group (P<0.01). No significant changes were found in the expression levels of Bax in the 3 needling groups relevant to the model group (P>0.05). CONCLUSION: Acupuncture of intraorbital and extraorbital acupoints can reduce apoptosis of retinal ganglion in NAION rabbits via inhibiting the activation of Caspase-3 protein and ratio of Bax/Bcl-2, and up-regulating the expression of Bcl-2 protein.

BACKGROUND: Many randomized controlled trials (RCTs) and systematic reviews (SRs) on acupuncture treatment for post-acute stroke dysphagia have been published. Conflicting results from different SRs necessitated an overview to summarize and assess the quality of this evidence to determine whether acupuncture is effective for this condition. The aim was to evaluate methodological quality and summarizing the evidence for important outcomes. METHODS: Seven databases were searched for SRs and/or meta-analysis of RCTs and quasi-RCTs on acupuncture for post-acute stroke dysphagia. Two authors independently identified SRs and meta-analyses, collected data to assess the quality of included SRs and meta analyses according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the revised Assessment of Multiple Systematic Reviews (AMSTAR 2). RESULTS: Searches yielded 382 SRs, 31 were included. The quality of 22 SRs was critically low, five SRs were low, and four Cochrane SRs were moderate when evaluated by AMSTAR2. A total of 17 SRs reported 85.2-96.3% of PRISMA items. Five SRs included explanatory RCTs, 16 SRs included pragmatic RCTs, and 10 SRs included both. CONCLUSION: Currently, evidence on the effectiveness of acupuncture on post-acute stroke dysphagia is of a low quality. The type of study appeared to have no direct influence on the result, but the primary outcome measures showed a relationship with the quality of SRs. High quality trials with large sample sizes should be the focus of future research.
