Efficacy and safety of acupuncture for depression: A systematic review and meta-analysis

Acupuncture is widely accepted as a therapeutic option for managing depression. However, evidence from clinical trials remains controversial. This review aims to synthesize the best available evidence on the efficacy and safety of acupuncture in managing depression. The review was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. Five databases and the relevant trial registries were searched from the inception to October 2021. Randomized clinical trials of acupuncture for managing depression, published in English, were selected for inclusion. The quality of included studies was assessed using the Cochrane risk of bias tool. Netmeta and dmetar of R packages were used to conduct a network meta-analysis. Twenty-two trials with 2391 participants were eligible and included in the analysis. This review found evidence that electroacupuncture (EA) plus antidepressant achieved superior outcomes compared with the waitlist (standardized mean difference = −8.86, 95% confidence interval: −14.78 to −2.93). The treatment ranking of different interventions in improving depression symptoms indicated that EA plus antidepressant with a probability of 0.8294, followed by manual acupuncture (MA) plus antidepressant (0.6470) and MA (0.5232). Acupuncture, either in isolation or as an adjunct to pharmacological treatment, has clinical benefits and can be considered a safe option for managing depression.     

Acupuncture for Uremic Pruritus: A Systematic Review and Meta-Analysis

Uremic pruritus (UP) is a chronic disease that can seriously affect the quality of life of dialysis patients. Acupuncture is a non-medication therapy that has been used to treat pruritus disorders. This systematic review aimed to evaluate the efficacy and safety of acupuncture for the treatment of UP. A total of nine Chinese and English databases were searched from their inception to December 31, 2021, and 214 studies were retrieved. Finally, seven randomized controlled trials (n=504) were included in the meta-analysis performed using RevMan V.5.3. Results included effective rate, recurrence rates, and adverse events. Compared with conventional treatment, acupuncture was more effective in treating UP (risk ratio [RR]=1.28, 95% confidence interval [CI]=1.09 to 1.50, P=0.003). The results were consistent after sensitivity analysis (RR=1.38, 95% CI=1.21 to 1.57, P<0.00001). In subgroup analysis, the efficacy rates of acupuncture and medications (oral and topical) were comparable (RR=1.20, 95% CI=0.98 to 1.47, P=0.07). Acupuncture combined with hemodialysis was more effective than hemodialysis alone in relieving pruritus (RR=1.42, 95% CI=1.18 to 1.72, P=0.0002). Adverse events were reported in only three studies, including one case of hyperphosphatemia in the medications group (RR=0.29, 95% CI=0.01 to 7.06, P=0.45). None of the studies reported recurrence rates. In conclusion, acupuncture is a safe treatment modality for patients with UP receiving hemodialysis that can effectively improve UP symptoms, and acupuncture in combination with hemodialysis has more efficacy than hemodialysis alone in improving the UP symptoms.     

Can acupuncture combined with SSRIs improve clinical symptoms and quality of life in patients with depression? Secondary outcomes of a pragmatic randomized controlled trial

ObjectivesTo explore the effects of acupuncture (manual acupuncture or electroacupuncture) combined with SSRIs for moderate to severe depression improving major clinical symptoms and life quality of the patients on secondary outcomes.DesignPragmatic, parallel, randomized controlled trial.Setting6 hospitals in China.Interventions6 weeks of manual acupuncture (MA)+selective serotonin reuptake inhibitors (SSRIs), electroacupuncture (EA)+SSRIs, and SSRIs alone.Main outcome measuresThe primary outcome was response rate of 17-item Hamilton Depression Scale (HAMD-17) total score at 6^th week. The secondary outcomes reported in this analysis were HAMD-17 factor scores at 1^st, 2^nd, 4^th, 6^th, 10^th week and WHO Quality of Life-BREF (WHOQOL-BREF) scores at 6^th week.Results477 patients were randomly assigned into MA + SSRIs (n = 161), EA + SSRIs (n = 160), or SSRIs alone (n = 156) groups. For HAMD-17 (at 6^th week), the MA + SSRIs group was significantly better than the SSRIs alone group in retardation factor (p = 0.008), while the EA+SSRIs group was significantly better than the SSRIs alone group in anxiety/somatization factor (p<0.001) and sleep disturbance factor (p = 0.002). For WHOQOL-BREF (at 6^th week), the EA + SSRIs group, compared with the SSRIs alone group, produced a more significant improvement in the overall quality of life, general health, physical health, and psychological health (p<0.05). While, the MA + SSRIs group, compared to the SSRIs alone group, showed significant advantage only in psychological health (p = 0.023).ConclusionsEither MA or EA combined SSRIs treatment could improve symptoms and quality of life for patients with moderate to severe depression. The main limitation of this trial was not using a sham control therefore the placebo effect could not be excluded.     

Acupuncture analgesia for temporal summation of experimental pain: A randomised controlled study

Background: Temporal summation of pain, a phenomenon of the central nervous system (CNS), represents enhanced painful sensation or reduced pain threshold upon repeated stimulation. This pain model has been used to evaluate the analgesic effect of various medications on the CNS. Aims: The present study aimed to evaluate the effects and characteristics of analgesia induced by electroacupuncture (EA), manual acupuncture (MA) and non‐invasive sham‐acupuncture (SA) in healthy humans on temporal summation of pain. Methods: Thirsty‐six pain‐free volunteers were randomised into one of the three groups EA (2/100 Hz), MA or SA. Acupuncture intervention was on ST36 and ST40 on the dominant leg delivered by an acupuncturist blinded to the outcome assessment. Both subjects and the evaluator were blinded to the treatment allocation. Pain thresholds to a single pulse (single pain threshold, SPT) and repeated pulses electrical stimulation (temporal summation thresholds, TST) were measured before, 30 min after and 24 h after each treatment. Results: The baseline values of three groups were comparable. Compared to SA, EA significantly increased both SPT and TST immediately after the treatment on the treatment leg as well as 24 h after on both the treatment and non‐treatment legs (ANOVA, p < 0.05). MA also increased SPT and TST, but the changes were not significantly different from those induced by SA. Conclusion: EA induces bilateral, segmentally distributed and prolong analgesia on both SPT and TST, indicating a non‐centrally specific effect. This effect needs to be verified with heat or mechanical model and in pain patients.     

The Role of Skin Mast Cells in Acupuncture Induced Analgesia in Animals: A Preclinical Systematic Review and Meta-analysis

While mast cells (MCs) are previously well-known as a pathological indicator of pain, their role in alleviating pain is recently emerged in acupuncture research. Thus, this study systematically reviews the role of MC in acupuncture analgesia. Animal studies on MC changes associated with the acupuncture analgesia were searched in PubMed and EMBASE. The MC number, degranulation ratio and pain threshold changes were collected as outcome measures for meta-analyses. Twenty studies were included with 13 suitable for meta-analysis, most with a moderate risk of bias. A significant MC degranulation after acupuncture was indicated in the normal and was significantly higher in the pain model. In the subgroup analysis by acupuncture type, manual (MA) and electrical (EA, each P < .00001) but not sham acupuncture had significant MC degranulation. Meta-regression revealed the linear proportionality between MC degranulation and acupuncture-induced analgesia (P < .001), which was found essential in MA (P < .00001), but not in EA (P = .45). MC mediators, such as adenosine and histamine, are involved in its mechanism. Taken together, skin MC is an essential factor for acupuncture-induced analgesia, which reveals a new aspect of MC as a pain alleviator. However, its molecular mechanism requires further study.PerspectiveThis systematic review synthesizes data from studies that examined the contribution of skin MC in acupuncture analgesia. Current reports suggest a new role for skin MC and its mediators in pain alleviation and explain a peripheral mechanism of acupuncture analgesia, with suggesting the need of further studies to confirm these findings.

Acupuncture for schizophrenia: a systematic review and meta‐analysis

Background: Acupuncture is one of the most popular types of complementary/alternative medicine. It is sometimes used as a treatment for schizophrenia. Aims: The objective of this review is to assess systematically the clinical evidence for or against acupuncture as a treatment for schizophrenia. Methods: We searched 20 databases from their inception to May 2009 without language restrictions. All randomised clinical trials (RCTs) of acupuncture, with or without electrical stimulation or moxibustion for patients with schizophrenia were considered for inclusion. Results: Thirteen RCTs, all originating from China, met the inclusion criteria. One RCT reported significant effects of electroacupuncture (EA) plus drug therapy for improving auditory hallucunations and positive symptom compared with sham EA plus drug therapy. Four RCTs showed significant effects of acupuncture for response rate compared with antipsychotic drugs [n = 360, relative risk (RR): 1.18, 95% confidence interval (CI): 1.03–1.34, p = 0.01; heterogeneity: τ² = 0.00, χ² = 2.98, p = 0.39, I² = 0%]. Seven RCTs showed significant effects of acupuncture plus antipsychotic drug therapy for response rate compared with antipsychotic drug therapy (n = 457, RR: 1.15, 95% CI: 1.04–1.28, p = 0.008, heterogeneity: τ² = 0.00, χ² = 6.56, p = 0.36, I² = 9%). Two RCTs tested laser acupuncture against sham laser acupuncture. One RCT found beneficial effects of laser acupuncture on hallucination and the other RCT showed significant effects of laser acupuncture on response rate, Brief Psychiatric Rating Scale and clinical global index compared with sham laser. The methodological quality was generally poor and there was not a single high quality trial. Conclusion: These results provide limited evidence for the effectiveness of acupuncture in treating the symptoms of schizophrenia. However, the total number of RCTs, the total sample size and the methodological quality were too low to draw firm conclusions. As all studies originated from China, international studies are needed to test whether there is any effect.     

Acupuncture for the treatment of childhood anorexia: A systematic review and meta-analysis

ObjectivesChildhood anorexia, among the commonest symptoms of children, involved long-term loss of appetite/decreased food intake and refusal to try or eat certain foods. Acupuncture is increasingly popular in childhood anorexia due to the side effects and dissatisfaction of conventional treatment, but, the efficacy and safety of acupuncture for childhood anorexia have not been reviewed systematically.MethodsFrom 12 electronic databases, randomized controlled trials (RCTs) assessing acupuncture for childhood anorexia were identified in June 2021, with posttreatment improvement in clinical symptoms of anorexia as the primary outcome. A meta-analysis was conducted if two or more studies used the same interventions or same outcome measures. The risk of bias and quality of evidence were evaluated.ResultsA total of 32 RCTs with 3518 participants were included. When acupuncture was used as monotherapy or adjunctive therapy, the total effectiveness rate based on anorexia symptoms, hemoglobin levels, abdominal subcutaneous fat, and body weight significantly improved. However, results in nutritional indices were inconsistent. The recurrence rate of anorexia was significantly lower in the acupuncture group. No serious adverse events in relation to acupuncture were reported. in general, the risk of bias of the included studies was unclear and the quality of evidence for the main findings was low to moderate.ConclusionsAcupuncture may improve symptoms of childhood anorexia without serious adverse events. However, because of the low methodological quality and quality of evidence in existing reports, further high-quality clinical trials are needed to conclusively establish the efficacy and safety of this treatment.     

Acupuncture for treating diabetic retinopathy: A systematic review and meta-analysis of randomized controlled trials

ObjectiveThis review aimed to examine the effectiveness of acupuncture for the treatment of diabetic retinopathy (DR).MethodsFourteen databases (5 English, 4 Chinese, and 5 Korean) were searched from their inception until May 20, 2020. Randomized controlled trials (RCTs) using acupuncture for DR treatment were included. The study selection and data extraction were performed by two independent reviewers. The Cochrane risk of bias tool version 2 (RoB 2.0) and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) were used to assess all the included RCTs.ResultsOf 864 citations, 6 RCTs met the inclusion criteria of our review. Four studies reported the beneficial effects of acupuncture with standard medication or acupuncture alone compared with standard medication or no treatment on the effective rate. Only three studies showed that acupuncture combined with standard medications significantly improved visual acuity compared to standard medication alone. None of the studies reported on adverse events. The risk of bias of the included studies was judged to be of “some concern” and was marked with a moderate and low certainty of evidence in different outcomes.ConclusionOur results suggest the potential benefit of acupuncture in treating DR. Acupuncture in the form of combined therapy with standard medication or acupuncture alone may be more effective in the treatment of DR than standard medication alone. Further rigorous clinical trials are needed to confirm these findings.     

Acupuncture and moxibustion for endometriosis: A systematic review and analysis

ObjectivesThis study aimed to examine the effect of acupuncture on symptoms and health-related quality of life in patients with endometriosis.MethodsNine biomedical databases were searched to April 2022 to identify randomized controlled trials of acupuncture and/or moxibustion used alone or as adjunct to guideline-recommended pharmacotherapy for the treatment of endometriosis. One reviewer extracted data and another verified the data. A random effects model was used to calculate mean differences.ResultsFifteen trials involving 1018 patients met the inclusion criteria, but diversity in comparisons and outcome measures prevented meta-analysis. Compared to sham acupuncture, manual acupuncture was more effective at reducing dysmenorrhea VAS pain score (mean difference [MD] − 2.40, 95 % CI [− 2.80, − 2.00]; moderate certainty evidence), pelvic pain VAS score (MD − 2.65, 95 % CI [− 3.40, − 1.90]; high certainty evidence) and dyspareunia VAS scores (MD − 2.88, [− 3.83, − 1.93]), lessened the size of ovarian cyst (MD − 3.88, 95 % CI [− 7.06, − 0.70]), and improved quality of life. Compared to conventional therapy, manual acupuncture plus conventional therapy and warm needle alone resulted in greater improvements in quality of life than conventional therapy. Among the six studies that reported safety, fewer adverse events were reported in participants who received acupuncture or moxibustion.ConclusionsLow to moderate certainty evidence from single studies showed that manual acupuncture may improve pain-related symptoms and quality of life; however, there is insufficient evidence on the overall effectiveness of acupuncture and moxibustion for endometriosis.     

The effectiveness of acupuncture for Parkinson’s disease: An overview of systematic reviews

ObjectivesAcupuncture is an alternative therapy for Parkinson’s disease (PD), but its efficacy and safety are controversial. This overview aimed to summarize the existing evidence from systematic reviews (SRs) and meta-analyses (MAs) in order to assess the effectiveness of acupuncture as a treatment for PD.MethodsSeven electronic databases were searched from their inception until July 2019. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) and Assessment of Multiple Systematic Reviews 2 (AMSTAR2) checklists were used to assess evidence quality and methodological quality, respectively. The outcomes of study were calculated using mean differences (MDs) and risk ratios (RRs) with 95 % confidence intervals (CIs). A meta-analysis was performed using RevMan 5.3 software.ResultsA total of 12 SRs/MAs were included. All 12 SRs/MAs had more than one critical weakness in AMSTAR 2 and were considered of critically low methodological quality. The quality of evidence was unsatisfactory according to the GRADE checklist. Meta-analyses showed that acupuncture combined with drug for the treatment of PD can significantly improve the total effectiveness rate compared with drug alone (RR = 1.25, 95 % CI 1.16–1.34, P < 0.001). It was also found that acupuncture combined with drug significantly improved the UPDRS I–IV total summed scores (WMD=−6.18, 95 % CI -10.32 to –2.04, P < 0.001) and Webster scores (WMD=−4.20, 95 % CI -7.59 to –0.81, P < 0.001).ConclusionAcupuncture might improve the UPDRS score, Webster score, and total effective rate in treatment of PD. It might be a safe and useful adjunctive treatment for patients with PD. However, we should interpret the findings of these reviews with caution, considering the overall limited methodological and reporting quality.     

Acupuncture for oculomotor nerve palsy:A systematic review and meta-analysis

BackgroundTo evaluate the safety and efficacy of acupuncture in the treatment of oculomotor nerve palsy (ONP).MethodsThe following database will be required from PubMed, Cochrane Library, Medline, Chinese Biomedical Literature Database, China National Knowledge Infrastructure (CNKI), Wanfang data. Randomized controlled trials (RCTs) comparing acupuncture alone versus no treatment/another active therapy/sham acupuncture or comparing acupuncture with another active therapy versus the same active therapy were included. Meta-analysis was conducted according to the 2020 PRISMA guidelines. Data was analyzed using RevMan 5.4 software. Results were reported as risk ratios (RR) for dichotomous outcomes or mean differences (MD) for continuous outcomes, with 95 % confidence intervals (CI). The Cochrane risk of bias tool was used to access the methodological quality of the trails.ResultsEighteen RCTs with 1150 participants comparing acupuncture versus other therapies were included. The results showed a significant differences in the clinical efficiency rate (RR = 1.30, 95 %CI = 1.23–1.37, P < 0.001), scores of diplopia (MD = − 0.78, 95 %CI = − 1.39 to − 0.77, P < 0.001), palpebral fissure size (MD = 1.04, 95 %CI = 0.41–1.68, P = 0.001), the pupil diameter (MD = − 0.56, 95 %CI = − 0.70 to − 0.42, P < 0.001), quality of life (MD = 8.96, 95 %CI = 6.79–11.13, P < 0.001) between the experiment and control groups. However, there were no significant differences in the adverse effects (RR = 0.52, 95 %CI = 0.22–1.22, P = 0.13). The quality of the evidence test by GRADE was low or very low.ConclusionMost included studies suggested that acupuncture was more effective than the control group in the treatment of ONP. However, the quality evidence of most of the studies was low and most of them were performed in China.     

The Use of Acupuncture in the Management of Patients With Humeral Fractures: A Systematic Review and Meta-analysis

ObjectiveThe purpose of this study was to conduct a systematic review and meta-analysis of the effects of acupuncture on humeral fractures.MethodsRandomized controlled trials were searched systematically from inception to January 2020 using the Cochrane Central Register of Controlled Trials, Embase, PubMed, Web of Science, China National Knowledge Infrastructure, and 7 Korean databases. Pain scale and Japanese Orthopaedic Association scores were the primary and secondary measurements. A risk-of-bias assessment and meta-analysis were conducted.ResultsSeven randomized controlled trials were included in the systematic review; the quality of the studies was ambiguous. The meta-analysis showed that acupuncture improved the pain severity score compared with conventional therapies (standard mean difference = ?4.55, 95% confidence interval, ?7.48 to ?1.61, I² = 98%, P < .00001) but did not improve the Japanese Orthopaedic Association score (standard mean difference = 4.99, 95% confidence interval, ?0.31 to 10.30, I² = 99%, P < .00001).ConclusionOur meta-analysis shows that acupuncture reduced pain after proximal humeral fracture, in addition to common rehabilitative modalities. However, the conclusion of this review should be cautiously applied in clinical practice owing to the low quality of the included studies.     

Clinical efficacy and safety of acupuncture treatment of TIC disorder in children: A systematic review and meta-analysis of 22 randomized controlled trials

ObjectiveTo systematically evaluate the clinical efficacy and safety of acupuncture in the treatment of Tic Disorders (TD) in children, and to clarify the current evidence regarding the clinical application of acupuncture in the treatment of TD.MethodsRandomized controlled trials (RCTs) comparing acupuncture treatment with pharmaceutical treatment for TD were included in this review. A comprehensive search of 6 electronic literature databases was conducted, and the retrieval date was from the establishment of the database to April 2020. The Cochrane Collaboration’s bias risk assessment tool was used to evaluate the bias risk of the included literature, and adopted the Review Manager 5.3 was used for statistical analysis of the data in the included literature.ResultsA total of 22 RCTs (1668 participants) were included in this review. Meta-analysis indicated that acupuncture showed superior effects in the following aspects, including higher overall effective rate [RR = 1.20,95 % CI(1.09,1.20),P＜0.00001], significant reduction in Yale Global Tic Severity Scale (YGTSS) scores [MD=-2.79,95 %CI(-4.75,-0.82),P = 0.005], lower incidence of adverse effects [RR = 0.26,95 %CI(0.17,0.41),P＜0.00001], and reduced recurrence rate [RR = 0.28,95 %CI(0.17,0.46),P＜0.00001].ConclusionAcupuncture treatment alone is more effective in the treatment of TD than pharmaceutical treatment, as seen in the reduction of YGTSS scores, fewer adverse effects and lower recurrence rates.     

Acupuncture for Breathlessness in Advanced Diseases: A Systematic Review and Meta-analysis

ContextNonpharmacological approaches are effective strategies for difficult to palliate breathlessness. Although acupuncture is effective for dyspnea in early-stage chronic obstructive pulmonary disease (COPD), little is known about its effects in patients with advanced (non)malignant diseases.ObjectivesThe objective of this study was to identify and examine the evidence of acupuncture on breathlessness in advanced malignant and nonmalignant diseases.MethodsSystematic literature review of randomized controlled trials of acupuncture and acupressure searched in five databases. Included were adult participants with at least 25% having advanced diseases such as cancer or COPD with severe breathlessness. Primary outcome was severity of dyspnea on Visual Analogue Scale or Borg Scale. Secondary outcomes included quality of life, function, and acceptability. Data were pooled using a random effects model of standardized mean differences.ResultsTwelve studies with 597 patients (347 COPD, 190 advanced cancer) were included. For breathlessness severity, significant differences were obtained in a meta-analysis (10 studies with 480 patients; standardized mean difference (SMD) = −1.77 [95% CI −3.05, −0.49; P = 0.007; I² = 90%]) and in a subgroup analysis of using sham acupuncture control groups and a treatment duration of at least three weeks (6 studies with 302 patients; SMD = −2.53 [95% CI −4.07, −0.99; P = 0.001; I² = 91%]). Exercise tolerance (6-minute walk test) improved significantly in the acupuncture group (6 studies with 287 patients; SMD = 0.93 [95% CI 0.27, 1.59; P = 0.006; I² = 85%]). In four of six studies, quality of life improved in the acupuncture group.ConclusionAcupuncture improved breathlessness severity in patients with advanced diseases. The methodological heterogeneity, low power, and potential morphine-sparing effects of acupuncture as add-on should be further addressed in future trials.     

Clinical evidence for acupuncture for adult asthma: Systematic review and meta-analysis of randomised sham/placebo-controlled trials

ObjectiveAcupuncture is a widely used asthma therapy, but the benefits remain uncertain. This study aimed to access the effectiveness of acupuncture for treatment of asthma in adults.MethodsFive English databases and four Chinese databases were searched from inception to November 2021. Randomised sham/placebo-controlled trials meeting inclusion criteria were included. Risk of bias was evaluated according to the Cochrane Review Handbook, and data analysis was performed in RevMan 5.4.1. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluations (GRADE) profiler.ResultsSixteen randomised controlled trials (RCTs) were included in the meta-analysis. Results indicated that acupuncture was well-tolerated and could improve FEV1% compared with sham/placebo acupuncture [MD 6.11, 95% CI 0.54–11.68, I² = 93%, number of participants (n) = 603]. Acupuncture also improved Cai’s Asthma Quality of Life Questionnaire (AQLQ) (MD 7.26, 95% CI 5.02–9.50, I² = 0, n = 358), and reduced the asthma symptom score (SMD −2.73, 95% CI −3.59 to −1.87, I² = 65%, n = 120). One study showed acupuncture increased the Asthma Control Test (ACT) score (MD 2.00, 95% CI 0.90–3.10, n = 111), and decreased exacerbation frequency (MD −1.00, 95% CI −1.55 to −1.45, n = 111). Other lung function and medication use parameters were not statistically significant.ConclusionsAcupuncture versus sham/placebo control appeared to improve quality of life, FEV1%, symptoms, and asthma control, and reduced exacerbation frequency per year. Further studies with appropriate controls, more participants, and high-quality evidence are needed.     

Electro-acupuncture vs. sham electro-acupuncture for chronic severe functional constipation: A systematic review and meta-analysis

ObjectivesTo assess the efficacy of electro-acupuncture (EA) relative to sham electro-acupuncture (sham EA) in treating chronic severe functional constipation (CSFC). Methods: A comprehensive search for relevant studies published between January 1, 1951 and May 14, 2020 was conducted in PubMed, the Cochrane Library, Chinese Biomedical Literature Database, Web of Science, and EMbase. Two investigators independently selected studies, extracted data, and assessed the quality of the included studies. The software Endnote X9 was used for screening articles, and the Review Manager 5.3 for analyzing data.ResultsThe meta-analyses involved 6 studies and 1457 individuals. The pooled results favored the EA group for the increase of complete spontaneous bowel movements (CSBMs) per week in the fourth week (MD = 0.80, P = 0.001) during treatment, and further improved in the eight weeks (MD = 1.25, P < 0.001). During the follow-up period, significant changes in CSBMs per week were seen in the experimental group (MD = 1.38, P = 0.008); the effect decreased in the twelfth week (MD = 0.87, P < 0.001). There was no significant difference in the Bristol stool scale score between the two groups in the fourth week (MD = 0.40, P = 0.08), but significant differences were observed in the eighth week (MD = 0.40, P = 0.03). A significant reduction in patient assessment of constipation quality of life (PAC-QOL) score were observed in the EA group during treatment (SMD = -0.83, P < 0.001). No serious adverse events were reported.ConclusionsEA had favorable effects on CSFC, and the longer the treatment duration was, the better was the effect, but the effect showed a certain period of validity. However, the results may be influenced by the clinical heterogeneity of acupuncture points, depth of needling, intensity, and frequency of EA.     

Effect of Chinese medicine for promoting blood circulation on microvascular angina: A systematic review and meta-analysis

BackgroundBlood-activating drugs (BADs) are widely used to treat microvascular angina in China. This study aims to summarize relevant evidence from randomized controlled trials (RCTs) to assess the efficacy and safety of BADs in the treatment of microvascular angina.MethodsWe searched for relevant studies before June 2019 from seven databases. Twenty-four studies were included of 1903 patients with microvascular angina. All studies compared the use of traditional Chinese medicine for activating blood circulation (BADs) and Western medicine (WM) with the use of Western medicine alone.ResultsIn all, 15 trials reported a significant effect of BADs on improving clinical symptoms compared with the control treatment (P < .00001), and 8 trials reported significant effects of BADs on reducing the frequency of angina pectoris attacks compared with Western medicine treatment (P < .00001). The pooled results also demonstrated that BADs provided a significant benefit in reducing the dosage of nitroglycerin required (P = .02), the maximum range of ST-segment depression (P = .003) and the descending degree of the ST-T segment of ECG (P = .0002); prolonging the total time of treadmill exercise (P < .00001) and the time of ST-segment depression of 1 mm (P = .002); enhancing the total effective rate of Traditional Chinese Medicine (TCM) syndromes (P < .00001); improving endothelial function (P < .00001); and reducing the levels of high-sensitivity C-reactive protein (hs-CRP) (P < .00001). BAD treatment showed no statistically significant effect on the levels of TNF-a (P = .8) or IL-6 (P = .13). No severe adverse events were reported.ConclusionThis meta-analysis shows that BADs are effective for the treatment of microvascular angina. Although concerns regarding selective bias and low methodological quality were raised, our findings suggest that BADs are beneficial for patients with microvascular angina and should be given priority for future clinical studies.     

Assessment of anti-inflammatory efficacy of acupuncture in patients with inflammatory bowel disease: A systematic review and meta-analysis

BackgroundInflammation has a significant role in the onset and progression of inflammatory bowel disease (IBD). Increasing attention has been paid to the use of acupuncture in IBD patients; however, its regulatory effects on inflammatory factors in IBD still require validation. Here, we systematically evaluated the effects of acupuncture on inflammatory factors in IBD patients.MethodsEight electronic databases were searched for studies that met the inclusion criteria. After evaluating the quality of the studies selected by two reviewers, the meta-analysis was performed to assess the efficacy of acupuncture in IBD patients and the impact on inflammatory factors (TNF-α, IL-1, IL-8 and IL-10).ResultsFour randomized controlled trials with a total of 228 patients satisfied the inclusion criteria. Acupuncture has a positive therapeutic impact on IBD (MD = 1.22, 95% CI [1.07, 1.39], P = 0.003). Moreover, it regulates the levels of TNF-α (MD =−60.58, 95% CI [−100.30, −20.89], P = 0.003), IL-8 (MD =−56.40, 95% CI [−60.02, −52.14], P < 0.00001) and IL-10 (MD =35.96, 95% CI [11.02, 60.91], P = 0.005) in IBD patients. However, the P value of meta-analysis in IL-1 great than 0.05.(MD =−27.90, 95% CI [−97.82, 42.02], P = 0.11).ConclusionAcupuncture has a positive therapeutic impact on IBD and can effectively regulate inflammatory factors in IBD patients. TNF-α, IL-8 and IL-10 are more appropriate inflammatory indicators for clinically evaluating the anti-inflammatory response in the blood of IBD patients by acupuncture.
