RESUMO
BACKGROUND: Long-term effects of individualized acupuncture in persons with chronic neck pain (CNP) remain unknown. OBJECTIVE: To evaluate the efficacy and safety of pressure pain, sensory-based individualized acupuncture for relieving CNP. DESIGN: A 24-week multicenter randomized controlled clinical trial. (ChiCTR1800016371). SETTING: Outpatient settings at 4 clinical centers in China from May 2018 to March 2020. PARTICIPANTS: 716 participants with CNP. INTERVENTION: Participants were randomly assigned to a waiting list (WL) group or to 1 of 3 interventions, which consisted of 10 sessions over 4 weeks: higher sensitive acupoints (HSA), lower sensitive acupoints (LSA), and sham acupoints (SA) acupuncture groups. MEASUREMENTS: The primary outcome was the change in the visual analogue scale (VAS) score for neck pain (range, 0 to 100) from baseline to 4 weeks, with a difference of 10 points considered the minimum clinically important threshold. The VAS was also assessed every 4 weeks through 24 weeks. RESULTS: The modified intention-to-treat population included 683 participants. The mean baseline VAS was 50.36, 50.10, 49.24, and 49.16 for HSA, LSA, SA, and WL, respectively. Compared with a mean baseline to week 4 change of -12.16 in the HSA group, the mean changes were -10.19 in the LSA group (net difference [ND], -1.97 [95% CI, -5.03 to 1.09]), -6.11 in the SA group (ND, -6.05 [CI, -9.10 to -3.00]), and -2.24 in the WL group (ND, -9.93 [CI, -12.95 to -6.90]). The intervention effects persisted at 24-week follow-up. LIMITATION: Lack of complete blinding and limited generalizability. CONCLUSION: Individualized acupuncture interventions using high- or low-sensitivity acupuncture points were more effective in reducing CNP than SA and WL control groups sustained through 24 weeks, but the magnitude of relative improvement did not reach a minimal clinically important difference.

RESUMO
BACKGROUND: The effectiveness and safety of acupuncture therapy to delay lung function decline in chronic obstructive pulmonary disease (COPD) remain unclear. This study aimed to determine whether acupuncture, as an adjunctive therapy to COPD-guided medication, could prevent lung function decline. METHODS: This randomised, two-centre study was conducted between February 2022 and July 2023. Men and women aged 40-80 years with COPD were recruited. Participants received active or sham acupuncture three times a week (36 sessions total). The primary outcome was the change in the percentage of forced expiratory volume for 1 s to the predicted value (FEV1%) between the baseline and after the intervention. RESULTS: Overall, 238 participants were screened, and 74 (58 men [78.4%]; mean [standard deviation] age, 69.6 [7.2] years) were randomised into the acupuncture and sham acupuncture groups (37 per group). After the intervention, the change in FEV1% was 1.35 (95% confidence interval [CI]: -0.47 to 3.17) and -2.44 (95% CI: -4.56 to -0.33) in the acupuncture and sham acupuncture groups, respectively. The difference was -3.97 (95% CI: -6.2 to -1.74), and the adjusted difference was -3.46 (95% CI: -5.69 to -1.24, P = 0.003) between the groups. A significantly less decline was found in forced expiratory volume for 1 s in the acupuncture group. All treatment-related adverse events (acupuncture = 11, sham = 2) were mild. CONCLUSIONS: Compared with sham acupuncture, acupuncture plus medication may delay lung function decline. However, further studies with a larger sample size and longer-term follow-up are needed to clarify the effects.

OBJECTIVES: This meta-analysis aimed to explore the relationship between the dose of acupuncture sessions, acupuncture frequency, and acupuncture duration and its effects on migraine. METHODS: Eight databases were searched for randomized controlled trials (RCTs) evaluating the efficacy of penetrating manual acupuncture for migraine published in English and Chinese from inception to June 20, 2024. The robust-error meta-regression (REMR) approach and non-linear meta-regression with restricted cubic spline (RCS) were used to investigate the dose-response association between acupuncture sessions, acupuncture frequency, and acupuncture duration and the frequency of migraine attacks. The potential nonlinear relationships was tested by restricting the regression coefficient to zero and a P valueï¼0.1. The statistical analysis was conducted using Stata 17.0. The risk of bias was independently assessed by two reviewers using the Cochrane tool. The reporting quality for acupuncture procedures was evaluated by STRICTA criteria. RESULTS: Thirty-two RCTs involving 1562 participants were included, and the results showed a J-shaped dose-response association between acupuncture sessions, acupuncture frequency, and acupuncture duration and migraine attack frequency. After 16 acupuncture sessions, the change in the frequency of migraine attacks was 3.95 (95%CI: 3.13 to 4.77). Three sessions of acupuncture a week resulted in a significant decrease in the frequency of migraine attacks, reaching 4.04 (95% CI: 2.49 to 5.58). After two months of acupuncture, the frequency of migraine attacks decreased significantly, showing a difference of 4.05 (95% CI: 3.61 to 4.49). Subsequently, the improvement trend gradually flattened, yielding diminishing benefits to patients. The risk of bias showed that seven studies were rated as "low risk", two were rated as "high risk", and the others were rated as "unclear risk". The reporting quality of RCTs of acupuncture for migraine remain suboptimal. CONCLUSIONS: A non-linear dose-response relationship was found between acupuncture sessions, acupuncture frequency, and acupuncture duration and migraine attack frequency. The results of our study recommend 16 sessions of acupuncture with a frequency of 3 sessions/week and a treatment duration of 1.5 to 2 months. REGISTRATION NUMBER: This meta-analysis has been registered on PROSPERO (CRD42023400493).
RESUMO
Paclitaxel (trade name Taxol) is a rare diterpenoid with anticancer activity isolated from Taxus. At present, paclitaxel is mainly produced by the semi-synthetic method using extract of Taxus tissues as raw materials. The studies of regulatory mechanisms in paclitaxel biosynthesis would promote the production of paclitaxel through tissue/cell culture approaches. Here, we systematically identified 990 transcription factors (TFs), 460 microRNAs (miRNAs), and 160 phased small interfering RNAs (phasiRNAs) in Taxus chinensis to explore their interactions and potential roles in regulation of paclitaxel synthesis. The expression levels of enzyme genes in cone and root were higher than those in leaf and bark. Nearly all enzyme genes in the paclitaxel synthesis pathway were significantly up-regulated after jasmonate treatment, except for GGPPS and CoA Ligase. The expression level of enzyme genes located in the latter steps of the synthesis pathway was significantly higher in female barks than in male. Regulatory TFs were inferred through co-expression network analysis, resulting in the identification of TFs from diverse families including MYB and AP2. Genes with ADP binding and copper ion binding functions were overrepresented in targets of miRNA genes. The miRNA targets were mainly enriched with genes in plant hormone signal transduction, mRNA surveillance pathway, cell cycle and DNA replication. Genes in oxidoreductase activity, protein-disulfide reductase activity were enriched in targets of phasiRNAs. Regulatory networks were further constructed including components of enzyme genes, TFs, miRNAs, and phasiRNAs. The hierarchical regulation of paclitaxel production by miRNAs and phasiRNAs indicates a robust regulation at post-transcriptional level. Our study on transcriptional and posttranscriptional regulation of paclitaxel synthesis provides clues for enhancing paclitaxel production using synthetic biology technology.
RESUMO
INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD) is a globally common chronic respiratory disease with a high morbidity and mortality rate. Acupuncture has been proven effective for COPD. A dose-response meta-analysis was conducted to assess the correlation between the acupuncture temporal parameters(session, frequency, and duration) and its effectiveness in patients with stable COPD. METHODS: Acupuncture randomized controlled trials on COPD were searched in eight databases from their inception to June 2023. The "doses" were defined as the acupuncture session, frequency, and duration. The outcomes mainly included Forced Expiratory Volume in one-second rate (FEV1%) and Six-minute Walking Distance (6MWD). The assessment of bias risk and literature quality were conducted independently using the Cochrane risk of bias tool and the Standards for reporting interventions in clinical trials of acupuncture. The dose-response relationship was modeled using robust error element regression, and meta-analysis was operated by R 4.3.1 and Stata 15.0. The protocol was registered in PROSPERO with the registration number CRD42023401406. RESULT: Out of 1669 records, 17 RCTs with 1165 participants were finally included in the meta-analysis. There was notable heterogeneity among the studies, but sensitivity analysis demonstrated good robustness. The findings revealed a significant improvement in the following outcomes for stable COPD patients in the acupuncture group: FEV1% (MD=3.50, 95%CI: 2.05-4.95), 6MWD (MD=47.39, 95%CI: 29.29-65.50), St. George's respiratory questionnaire (SGRQ; MD=-8.25, 95%CI: -11.38 to -5.12); COPD assessment test (CAT; MD=-2.91, 95%CI: -3.99 to -1.83). The relationship between the acupuncture session, duration, and FEV1%, 6MWD followed a "Λ" curve pattern, while the relationship between acupuncture frequency and FEV1%, 6MWD exhibited logarithmic growth. Firstly, After 12 acupuncture sessions, FEV1% and 6MWD increased by 7.06% (95%CI: 4.56-9.55) and 36.28 m (95%CI: 20.37-52.20), respectively. The peak improvement in FEV1% and 6MWD was observed after 18 acupuncture sessions (MD=7.89, 95% CI: 5.33-10.45) and 45 sessions (MD=125.43, 95% CI: 72.80-178.07) each. Additionally, weekly acupuncture resulted in a 4.14% improvement in FEV1% (95% CI: 2.55-5.72) and a 42.49 m increase in 6MWD (95%CI: 17.16-67.81). Notably, the maximum effects on FEV1% and 6MWD improvement were achieved with different acupuncture frequencies, specifically three times a week (MD=6.00, 95% CI: 5.34-6.66) and once a day(MD=112.41, 95% CI: 77.27-147.56), respectively. Furthermore, after a 28-day duration of acupuncture treatment, FEV1% increased by 4.74% (95% CI: 3.73-5.75) and 6MWD increased by 47.34 m (95%CI: 22.01-72.67). During 60 days of acupuncture treatment, the FEV1% and 6MWD improvement reached their highest levels at 8.76% (95% CI: 7.05-10.47) and 88.06 m (95% CI: 45.96-130.16), respectively. CONCLUSION: Acupuncture was effective in improving FEV1%, 6MWD, SGRQ, and CAT in patients with stable COPD. There was a dose-response relationship between the time parameters of acupuncture (session, frequency, and duration) and the efficacy of COPD treatment (FEV1% and 6MWD). The minimal clinically important difference could be achieved after 12 acupuncture sessions. Acupuncture with a medium-frequency (2-3 times per week) over 60 days may result in the greatest improvement in FEV1%, while higher-frequency acupuncture (5-7 times per week) for 2 months may lead to the maximum improvements in 6MWD. It indicated that the optimal acupuncture duration for different indicators remains consistent, while the optimal frequencies may differ. To confirm these results, it is necessary to conduct multicenter, large-scale randomized controlled trials. ETHICS AND DISSEMINATION: Ethical approval is not required for literature-based studies. The results will be published in peer-reviewed journals or conferences.

OBJECTIVE: To evaluate the efficacy of a new mechanochemical ablation (MOCA) device versus endovenous laser ablation (EVLA) for primary great saphenous vein (GSV) reflux. MATERIALS AND METHODS: Prospectively analyze the demographics, treatment detail and outcomes data of 57 primary GSV reflux patients. Patients were randomly assigned to MOCA or EVLA group with random envelope method. Primary endpoint was 6-month closure rate of GSV. Secondary endpoint including technical success rate, the venous clinical severity score (VCSS), chronic venous insufficiency questionnaire (CIVIQ-20) score and visual analogue scale (VAS) for pain. RESULTS: The procedures were well tolerated according to the VAS score. The 6-month closure rate was 85.71% in MOCA and 96.55% in EVLA group (p = .194). Significant changes were observed in regard of VCSS and CIVIQ-20 score at 6-month follow-up. Skin paresthesia occurred in 0 in MOCA and 5 in EVLA group. CONCLUSION: The new MOCA device is safe and effective in treating primary great saphenous vein reflux. The 6-month closure rate is non-inferior compared with EVLA. However, the long-term results need further follow-up.
RESUMO
BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common respiratory disease and the third leading cause of death worldwide. Previous evidence has shown that acupuncture may be an effective complementary alternative therapy for stable COPD. However, large-sample, rigorously designed long-term follow-up studies still need to be completed. Notably, the relationship between the frequency of acupuncture and clinical efficacy in studies on acupuncture for stable COPD still needs further validation. This study aims to evaluate the efficacy and safety of acupuncture for stable COPD and further investigate the dose-effect relationship of acupuncture. METHODS/DESIGN: This is a multicenter, randomized, controlled trial that uses central randomization to randomly allocate 550 participants in a 1:1:1:1:1 ratio to once a week acupuncture group, twice a week acupuncture group, three times a week acupuncture group, sham acupuncture group and waiting-list control group. The sham acupuncture group will receive placebo acupuncture treatments three times per week, and the waiting-list control group will not receive any form of acupuncture intervention. The study consists of a 2-week baseline, 12-week of treatment, and 52-week of follow-up. Patients with COPD between 40 to 80 years old who have received stable Western medication within the previous 3 months and have had at least 1 moderate or severe acute exacerbation within the past 1 year will be included in the study. Basic treatment will remain the same for all participants. The primary outcome is the proportion of responders at week 12. Secondary outcomes include the proportion of responders at week 64, change in the St. George's Respiratory Questionnaire (SGRQ) Scale, change in the Modified-Medical Research Council (mMRC) Scale, change in the COPD Assessment Test (CAT) Scale, change in the Lung Function Screening Indicators (LFSI), change in the 6-min walk distance (6-MWD), change in Short-Form 36 Health Survey (SF-36) Scale, the number of moderate and severe acute exacerbations and adverse event rate during the follow-up period. DISCUSSION: This study will provide robust evidence on whether acupuncture is safe and effective for treating stable COPD. Meanwhile, comparing the differences in efficacy between different acupuncture frequencies will further promote the optimization of acupuncture for stable COPD. TRIAL REGISTRATION: This study was registered in the Chinese Clinical Trial Registry (ChiCTR2200058757), on April 16, 2022.

Purpose: The effect of acupuncture as adjunctive therapy for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) was controversial. Thus, we aimed to evaluate the effects of acupuncture for treating AECOPD. Methods: Eight databases were searched from database inception to July 30, 2023. All RCTs compared acupuncture plus conventional western medicine with conventional western medicine alone were included. Outcomes were quality of life, lung function, blood oxygen condition, exercise capacity, daily symptoms, duration of hospitalization, and adverse events. The statistical analyses were conducted using Stata 17.0, and methodological quality was measured by the Cochrane bias risk assessment tool. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of evidence. Results: Twelve studies including 915 patients were included. Compared with conventional western medicine alone, acupuncture combined with conventional western therapy significantly improved quality of life (CAT: MD: -3.25; 95% CI: -3.73 to -2.78, P<0.001) and arterial blood gas (PaCO2: MD: -1.85; 95% CI: -2.74 to -0.95, P<0.001; PaO2: MD: 5.15; 95% CI: 1.22 to 9.07, P = 0.01). And for lung function, statistical benefits were found in FEV1/FVC (MD: 4.66; 95% CI: 2.21 to 7.12, P<0.001), but no difference was seen for FEV1% (MD: 1.83; 95% CI: -0.17 to 3.83, P = 0.073). There was no significant improvement in exercise capacity (6MWD: MD: 96.69; 95% CI: -0.60 to 193.98, P = 0.051), hospitalization duration (MD: -5.70; 95% CI: -11.97 to 0.58, P = 0.075), and dyspnea (mMRC: MD: -0.19; 95% CI: -0.61 to 0.63, P = 0.376) between two groups. Overall bias for CAT and mMRC was in "high" risk, FEV1%, FEV1/FVC, PaCO2, and PaO2 was in "some concern" and 1 RCT assessing hospitalization duration was in "low" risk. And the overall assessments were either moderate, low or very low certainty. Seven trials performed safety assessment of acupuncture, and no serious adverse events were reported. Conclusion: Acupuncture might have auxiliary effects on AECOPD. However, the quality of the evidence is limited, and more high-quality RCTs are needed to be performed in the future.

Migraine without aura is a multidimensional neurological disorder characterized by sensory, emotional, and cognitive symptoms linked to structural and functional abnormalities in the anterior cingulate cortex. Anterior cingulate cortex subregions play differential roles in the clinical symptoms of migraine without aura; however, the specific patterns and mechanisms remain unclear. In this study, voxel-based morphometry and seed-based functional connectivity were used to investigate structural and functional alterations in the anterior cingulate cortex subdivisions in 50 patients with migraine without aura and 50 matched healthy controls. Compared with healthy controls, patients exhibited (1) decreased gray matter volume in the subgenual anterior cingulate cortex, (2) increased functional connectivity between the bilateral subgenual anterior cingulate cortex and right middle frontal gyrus, and between the posterior part of anterior cingulate cortex and right middle frontal gyrus, orbital part, and (3) decreased functional connectivity between the anterior cingulate cortex and left anterior cingulate and paracingulate gyri. Notably, left subgenual anterior cingulate cortex was correlated with the duration of each attack, whereas the right subgenual anterior cingulate cortex was associated with migraine-specific quality-of-life questionnaire (emotion) and self-rating anxiety scale scores. Our findings provide new evidence supporting the hypothesis of abnormal anterior cingulate cortex subcircuitry, revealing structural and functional abnormalities in its subregions and emphasizing the potential involvement of the left subgenual anterior cingulate cortex-related pain sensation subcircuit and right subgenual anterior cingulate cortex -related pain emotion subcircuit in migraine.

OBJECTIVE: Acupuncture has shown promise in treating neck pain. Clinical trials have shown mixed results, possibly due to heterogeneous methodologies and the lack of knowledge regarding underlying brain circuit mechanism of action. In this study, we investigated the specific contribution of the serotonergic system in treating neck pain, and the specific brain circuits involved. METHODS: A total of 99 patients with chronic neck pain (CNP) were randomized to receive true acupuncture (TA) or sham acupuncture (SA) 3 times weekly for 4 weeks. Patients with CNP in each group were assessed for primary outcomes by measuring the Visual Analog Scale (VAS) and the duration of each attack; secondary outcomes were measured using the Neck Disability Index (NDI), Northwick Park Neck Pain Questionnaire (NPQ), McGill Pain Questionnaire (MPQ), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) and the 12-item Short Form Quality Life Scale (SF-12); levels of functional circuits connectivity were assessed using resting-state functional magnetic resonance imaging in the dorsal (DR) and median (MR) raphe nucleus, before and after undergoing acupuncture. RESULTS: Patients receiving TA showed more extensive symptom improvement compared with SA. Regarding the primary outcomes, changes observed in the TA group were as follows: VAS = 16.9 mm (p < 0.001) and the duration of each attack = 4.30 h (p < 0.001); changes in the SA group: VAS = 5.41 mm (p = 0.138) and the duration of each attack = 2.06 h (p = 0.058). Regarding the secondary outcomes, changes in the TA group: NDI = 7.99 (p < 0.001), NPQ = 10.82 (p < 0.001), MPQ = 4.23 (p < 0.001), SAS = 5.82 (p < 0.001), SDS = 3.67 (p = 0.003), and SF-12 = 3.04 (p < 0.001); changes in the SA group: NDI = 2.97 (p = 0.138), NPQ = 5.24 (p = 0.035) and MPQ = 2.90 (p = 0.039), SAS = 1.48 (p = 0.433), SDS = 2.39 (p = 0.244), and SF-12 = 2.19 (p = 0.038). The modulatory effect of TA exhibited increased functional connectivity (FC) between the DR and thalamus, between the MR and parahippocampal gyrus, amygdala, and insula, with decreased FC between the DR and lingual gyrus and middle frontal gyrus, between the MR and middle frontal gyrus. Furthermore, changes in the DR-related circuit were specifically associated with the intensity and duration of pain, and the MR-related circuit was correlated with the quality of life with CNP. CONCLUSION: These results demonstrated the effectiveness of TA in treating neck pain and suggested that it regulates CNP by reconfiguring the function of the raphe nucleus-related serotonergic system.

Non-pharmacological interventions can improve the behavioural and psychological symptoms of dementia (BPSD). However, the optimal non-pharmacological treatments remain controversial. This study aimed to compare the efficacy of multiple non-pharmacological methods and identify the optimal therapy for BPSD. Potential randomised controlled trials (RCTs) were searched and selected from 15 databases and sources from the inception of the databases until 1 October 2022. Two independent authors implemented study screening, data extraction, and methodological quality assessment. Primary outcome was reduction of Neuropsychiatric Inventory (NPI). The secondary outcome were changes of Cornell Scale for Depression in Dementia (CSDD), the Cohen-Mansfield Agitation Inventory (CMAI), the Quality of Life in Alzheimer's Disease (QoL-AD), the Abilities of Daily Living scale, and the Apathy Evaluation Scale. Meta-analyses were performed using STATA v15.0 and ADDIS v1.16.8. The GRADE approaches were utilised to evaluate evidence quality. The present study included 43 RCTs with 4978 participants. The global methodological quality of the RCTs was moderate. Regarding NPI reduction, with moderate-certainty evidence, exercise plus treatment as usual (TAU) outperformed TAU (mean difference [MD]: -7.13; 95% confidence interval [CI]: -13.22, -0.76) and ranked as the optimal treatment. For reduction in CSDD, with low- to moderate-certainty evidence, massage plus TAU (MD: -15.26; 95% CI: -20.13, -10.52) and music plus TAU (MD: -2.40; 95% CI: -4.62, -0.12) were associated with greater reduction compared with TAU. For reduction in CMAI, with moderate-certainty evidence, aromatherapy plus massage (MD: -15.84; 95% CI: -29.76, -2.42) and massage plus music (MD: -13.12; 95% CI: -25.43, -0.76) were significantly more effective than TAU. For improvement in QoL-AD, with critically low- to low-certainty evidence, there were no statistical differences between any of non-pharmacological treatments and TAU. Due to the limited number of included studies, network meta-analysis was not performed for other outcomes. In conclusion, non-pharmacological treatments are effective for overall symptoms, depression, and agitation. Exercise plus treatment as usual may be an optimal non-pharmacological intervention for improving the overall BPSD. This may help to guide patients, doctors, and policymakers.
RESUMO
Background: The acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is a common respiratory disease among older adults, which imposes a significant burden on individuals and society and poses a major challenge to the global public health system due to its high morbidity and mortality. Acupuncture is effective for AECOPD, but its efficacy has been questioned due to the limited methodological quality. Thus, we aim to investigate the efficacy of acupuncture as adjunctive therapy for AECOPD and determine whether the efficacy of acupuncture differs with the type of acupoint combinations. Methods and analysis: This study proposes a prospective, multicenter randomized controlled trial that will comprise four groups, including two acupuncture treatment groups, one sham acupuncture group, and one basic treatment group. The acupuncture treatment groups will be distinguished by their focus on different patterns of acupoint combination, namely the Xi-cleft and He-sea acupoint combination and the Eight Confluence points acupoint combination, which may vary in clinical efficacy based on traditional acupuncture theories. The study aims to randomize 556 patients in a 1:1:1:1 ratio across the four groups. Each patient in acupuncture group or sham acupuncture group will receive routine drug therapy and 7 sessions of acupuncture treatment over 1 week. Participants in the basic treatment group will only receive routine drug therapy. The trial will be conducted in seven hospitals located in China. The primary outcomes in this trial will include differences in the Breathlessness, Cough, and Sputum Scale (BCSS) before randomization, 7 days after randomization, 5 and 9 weeks after randomization. Ethics and dissemination: Ethical approval was obtained from the Sichuan Regional Ethics Review of Committee on Traditional Chinese Medicine (Approval ID: 2022KL-068). The results of this study will be distributed through peer-reviewed journals.Clinical Trial Registration: ClinicalTrials.gov, identifier ChiCTR2200064484.

INTRODUCTION: Low back pain (LBP) is a major global public health problem and the majority (nearly 90%) of patients with LBP suffer from non-specific LBP (NSLBP). Acupuncture has been widely used for relieving pain and is recommended as a first-line treatment in LBP guidelines. However, the guidelines do not recommend a specific acupuncture temporal dosage. A Bayesian model-based network meta-analysis (MBNMA) will be conducted to optimise the dosages of time parameters (session, frequency and duration). METHODS AND ANALYSIS: The following databases will be searched from their inception until 1 July 2023: MEDLINE (via PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, Web of Science, Cumulative Index to Nursing & Allied Health Literature (CINAHL), alternative health research database (Alt HealthWatch), China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database for Chinese Technical Periodicals, ClinicalTrials.gov, the WHO's International Clinical Trial and Chinese Clinical Registry. RCTs assessing the effects of acupuncture on chronic NSLBP will be selected. The primary outcome measure will be the improvement in pain intensity at different acupuncture time points. The MBNMA will be performed using R V.4.2.1 with related R packages. Risk of Bias V.2.0 and Confidence in Network Meta-Analysis will be used to assess the evidence quality. ETHICS AND DISSEMINATION: Ethical approval is not required for literature-based studies. The results will be published in peer-reviewed journals or conferences.

PURPOSE: The objective was to determine the effectiveness and safety of paclitaxel-coated balloon angioplasty in hemodialysis patients with diabetic nephropathy (DN). MATERIALS AND METHODS: The outcomes of end-stage renal disease (ESRD) patients with peripheral artery disease (PAD) and treated with drug-coated balloon (DCB) angioplasty were retrospectively evaluated. The effectiveness outcomes were clinical improvement of the Rutherford classification and target lesion revascularization (TLR). Safety outcomes were all-cause mortality and amputation. RESULTS: Ninety-seven patients were treated with DCB angioplasty between December 2018 and December 2020. 87 (63.8±10.1 years) achieved technical success. Most patients had a Rutherford classification of at least grade 4. The mean lesion length was 169.8±73.8 mm, almost all had arterial calcification, and 31.0% had annular calcification. Wounds were present in 73.6% of the target limbs. The mean follow-up in this cohort was 13.4±7.4 months. The wound healing rate was 61.5% at the 12-month follow-up. All-cause mortality during 12 months of follow-up was 35.6%, amputation-free survival was 58.6%, and TLR was observed in 13 (15.3%) patients. At 3 and 12 months of follow-up, the Rutherford grade significantly improved (p<0.001). The Cox proportional hazards model revealed that wounds (hazard ratio [HR]=1.404, p=0.023) and annular calcification (HR=2.076, p=0.031) were independent predictors of amputation-free survival. CONCLUSIONS: Drug-coated balloon angioplasty in ESRD patients was effective and safe over the medium term. Wounds and annular calcification were independent predictors of amputation-free survival. CLINICAL IMPACT: The effectiveness of DCB angioplasty in ESRD patients and the factors affecting major outcome prognosis in this population remain limited. This study contributes valuable insights into the effectiveness and safety of paclitaxel-coated balloon angioplasty for PAD in hemodialysis patients. Medical professionals can now regard DCB angioplasty as a viable treatment. Identifying wound presence and annular calcification as predictors of amputation-free survival equips medical practitioners with a more tailored approach to patient management, potentially resulting in enhanced outcomes and more precise treatment strategies.
RESUMO
BACKGROUND: The utilization of acupuncture as a therapeutic intervention for the management of postoperative nausea and vomiting has experienced a notable increase in its popularity, and the purpose of this analysis is to provide a comprehensive understanding of the level of concern within the academic discipline and the main contributors and their partnership, as well as to identify research focal points and trends. METHODS: A comprehensive search was carried out to identify relevant articles on the topic of acupuncture therapy for PONV in the Web of Science and China National Knowledge Internet. The search spanned from January 1, 2011, to June 6, 2023. The annual publications were count to see the degree of scholarly attention devoted to the discipline and how it has changed over time. A statistical analysis of article distribution across various journals was conducted to serve a rough indicator for assessing the quality of articles. And a bibliometric analysis was conducted using the software CiteSpace to visually analyze various aspects of the literature. Analyze authors, institutions and countries to identify the main contributors and their collaborative relationship; and analyze keywords and references to explore research hotspots and trends. RESULTS: This study examined a comprehensive collection of 819 articles focused on acupuncture therapy for PONV, demonstrating a varying upward trend in the quantity of publications. Notably, the most productive author and institution were identified as Zheng Man and Guangzhou University of Traditional Chinese Medicine, respectively. While China had the highest number of publications, the United States held a greater prominence in this specific field. Collaboration among contributors was found to be weak. High-frequency keywords in the publications included "transcutaneous electrical acupoint stimulation," "electroacupuncture," "pain," and so forth. The literature with the highest citation count pertained to "Stimulation of the wrist acupuncture point PC6 for preventing postoperative nausea and vomiting," while the article with the highest centrality was "Consensus Guidelines for the Management of Postoperative Nausea and Vomiting." Several large clusters obtained from the references are also included "postoperative pain," "transcutaneous electrical acupoint stimulation". Nothing pertaining to mechanism study was found in the analysis results. CONCLUSION: The utilization of acupuncture for the treatment of postoperative nausea and vomiting has been gaining increasing recognition, although there remains room for improvement in the quality of research conducted in this area. Chinese authors and institutions have emerged as significant contributors to this field, while the United States has demonstrated greater proficiency in fostering collaborative efforts. It is imperative to enhance collaboration among these contributors. The current focal points of acupuncture for PONV encompass pain management, electroacupuncture, auricular acupuncture, and transcutaneous electrical acupoint stimulation. Additionally, TEA and enhanced recovery after surgery have been identified as the forefronts of research in this particular domain. In addition, there is still much room for research in the aspect of mechanism and insurance coverage. This study provides an in-depth perspective on acupuncture for PONV, which offers reference material for clinicians with rational choice of therapeutic scheme, educators with hot topics, and researchers with valuable research directions.

Atherosclerosis is a chronic lipid-driven inflammatory response of the innate and adaptive immune systems, and it is responsible for several cardiovascular ischemic events. The present study aimed to determine immune infiltration-related biomarkers in carotid atherosclerotic plaques (CAPs). Gene expression profiles of CAPs were extracted from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) between the CAPs and control groups were screened by the "limma" package in R software. Immune cell infiltration between the CAPs and control groups was evaluated by the single sample gene set enrichment analysis. Key infiltrating immune cells in the CAPs group were screened by the Wilcoxon test and least absolute shrinkage and selection operator regression. The weighted gene co-expression network analysis was used to identify immune cell-related genes. Hub genes were identified by the protein-protein interaction (PPI) network. Receiver operating characteristic curve analysis was performed to assess the gene's ability to differentiate between the CAPs and control groups. Finally, we constructed a miRNA-gene-transcription factor network of hub genes by using the ENCODE database. Eleven different types of immune infiltration-related cells were identified between the CAPs and control groups. A total of 1,586 differentially expressed immunity-related genes were obtained through intersection between DEGs and immune-related genes. Twenty hub genes were screened through the PPI network. Eventually, 7 genes (BTK, LYN, PTPN11, CD163, CD4, ITGAL, and ITGB7) were identified as the hub genes of CAPs, and these genes may serve as the estimable drug targets for patients with CAPs.

Purpose: To assess the inhibitory effect of acupuncture on pain symptoms in migraine models, and to further summarize the potential mechanisms of acupuncture in regulating hyperalgesia in the treatment of migraine. Materials and Methods: Literature search in databases such as China National Knowledge Infrastructure (CNKI), PubMed, and Web of Science (WOS) etc. The quality was evaluated by the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) bias risk assessment tool and Collaborative Approach to Meta-analysis and Review of Animal Data from Experimental Studies (CAMARADES) checklist. Meta-analyses were performed using Stata 17.0 software. Results: Twenty-one studies involving 489 animals were identified. The qualitative score ranged from 3 to 9 points. Facial mechanical withdrawal threshold (FMWT) and paw mechanical withdrawal threshold (PMWT) measured by Von Frey filaments were selected as major outcomes, and serum calcitonin gene-related peptide (CGRP) levels measured by ELISA were selected as secondary outcome. Meta-analysis results revealed that true acupuncture (TA) group significantly increased FMWT, PMWT and CGRP compared to model group. TA group showed superior effect in FMWT, PMWT relative to sham acupuncture (SA) group. Subgroup analysis results showed that high risk of bias scores may be responsible for the high heterogeneity of FMWT; additionally, CGRP analysis suggests that acupoint selection and blood collection sites may be sources of heterogeneity. In the treatment of migraine pain symptoms, the underlying mechanism of acupuncture treatment is either the regulation of hyperalgesia and neurotransmitters, or the reduction of inflammatory factors. Conclusion: The results indicate that TA treatment effectively increased the pain threshold and reduced hyperalgesia in migraine rats. In summary, our study highlights the potential of TA as an effective treatment for migraine, but further investigation is required to fully comprehend its mechanism of action and optimize its clinical application.
RESUMO
Background: Amnestic mild cognitive impairment (aMCI) is a pre-dementia condition associated with declined cognitive function dominated by memory impairment. The occurrence of aMCI is associated with the gut-brain axis. Previous studies have shown cognitive improvements in MCI after acupuncture treatment. This study evaluates whether acupuncture can produce a therapeutic effect in patients with aMCI by modulating the gut-brain axis. Methods and design: This is a prospective, parallel, multicenter randomized controlled trial. A total of 40 patients with aMCI will be randomly assigned to an acupuncture group (AG) or a waiting-list group (WG), participants in both groups will receive health education on improving cognitive function at each visit, and acupuncture will be conducted twice a week for 12 weeks in the AG. Another 20 matched healthy volunteers will be enrolled as normal control. The primary outcome will be the change in Alzheimer's Disease Assessment Scale-cognitive scale score before and after treatment. Additionally, functional magnetic resonance imaging data, faeces, and blood will be collected from each participant to characterize the brain function, gut microbiota, and inflammatory cytokines, respectively. The differences between patients with aMCI and healthy participants, and the changes in the AG and WG groups before and after treatment will be observed. Ultimately, the correlation among brain function, gut microbiota, inflammatory cytokines, and clinical efficacy evaluation in patients with aMCI will be analyzed. Discussion: This study will identify the efficacy and provide preliminary data on the possible mechanism of acupuncture in treating aMCI. Furthermore, it will also identify biomarkers of the gut microbiota, inflammatory cytokines, and brain function correlated with therapeutic effects. The results of this study will be published in peer-reviewed journals. Clinical trial registration: http://www.chictr.org.cn, identifier ChiCTR2200062084.
RESUMO
Migraine is a pervasive neurologic disease closely related to neurogenic inflammation. The astrocytes and microglia in the central nervous system are vital in inducing neurogenic inflammation in migraine. Recently, it has been found that there may be a crosstalk phenomenon between microglia and astrocytes, which plays a crucial part in the pathology and treatment of Alzheimer's disease and other central nervous system diseases closely related to inflammation, thus becoming a novel hotspot in neuroimmune research. However, the role of the crosstalk between microglia and astrocytes in the pathogenesis and treatment of migraine is yet to be discussed. Based on the preliminary literature reports, we have reviewed relevant evidence of the crosstalk between microglia and astrocytes in the pathogenesis of migraine and summarized the crosstalk pathways, thereby hoping to provide novel ideas for future research and treatment.
RESUMO
BACKGROUND AND OBJECTIVES: The objective of this study was to propose a clustering approach to identify migraine subgroups and test the clinical usefulness of the approach by providing prognostic information for electroacupuncture treatment selection. METHODS: Participants with migraine without aura (MWoA) were asked to complete a daily headache diary, self-rating depression and anxiety, and quality-of-life questionnaires. Whole-brain functional connectivities (FCs) were assessed on resting-state functional MRI (fMRI). By integrating clinical measurements and fMRI data, partial least squares correlation and hierarchical clustering analysis were used to cluster participants with MWoA. Multivariate pattern analysis was applied to validate the proposed subgrouping strategy. Some participants had an 8-week electroacupuncture treatment, and the response rate was compared between different MWoA subgroups. RESULTS: In study 1, a total of 97 participants (age of 28.2 ± 1.0 years, 70 female participants) with MWoA and 77 healthy controls (HCs) (age of 26.8 ± 0.1 years, 61 female participants) were enrolled (dataset 1), and 2 MWoA subgroups were defined. The participants in subgroup 1 had a significantly lower headache frequency (times/month of 4.4 ± 1.1) and significantly higher self-ratings of depression (depression score of 49.5 ± 2.3) when compared with participants in subgroup 2 (times/month of 7.0 ± 0.6 and depression score of 43.4 ± 1.2). The between-group differences of FCs were predominantly related to the amygdala, thalamus, hippocampus, and parahippocampal area. In study 2, 33 participants with MWoA (age of 30.9 ± 2.0 years, 28 female participants) and 23 HCs (age of 29.8 ± 1.1 years, 13 female participants) were enrolled as an independent dataset (dataset 2). The classification analysis validated the effectiveness of the 2-cluster solution of participants with MWoA in datasets 1 and 2. In study 3, 58 participants with MWoA were willing to receive electroacupuncture treatment and were assigned to different subgroups. Participants in different subgroups exhibited different response rates (p = 0.03, OR CI 0.086-0.93) to electroacupuncture treatment (18% and 44% for subgroups 1 and 2, respectively). DISCUSSION: Our study proposed a novel clustering approach to define distinct MWoA subgroups, which could be useful for refining the diagnosis of participants with MWoA and guiding individualized strategies for pain prophylaxis and analgesia.
