ABSTRACT
Chronic neuropathic pain has been one of the prominent causes of disability, and acupuncture has shown promise in treatment. The present study aimed to characterize acupuncture modulation of chronic neuropathic pain and explore the related functional brain changes. Sixty chronic sciatica patients were divided into acupuncture- or sham acupuncture groups and received 10 sessions of treatment during 4 weeks. The visual analog scale for leg pain, oswestry disability index (ODI), and resting-state functional magnetic resonance images were assessed at baseline and after treatment. Then, fractional amplitudes of low-frequency fluctuations (fALFF) and support vector regression analyses were performed. Compared with sham acupuncture, acupuncture significantly improved symptoms, including visual analog scale for leg pain and ODI. In addition, acupuncture exhibited increased fALFF of the right superior parietal lobule (SPL) and right postcentral gyrus. Furthermore, the actual 4-week ODI values were positively correlated with the support vector regression-predicted values based on the right SPL fALFF and baseline clinical measurements. These results indicate that the spontaneous neural activity of the right SPL and right postcentral gyrus may be involved in the modulation of acupuncture in chronic neuropathic pain. In addition, the spontaneous neural activity of the right SPL might be used as the predictor of response to acupuncture therapy. PERSPECTIVE: This clinical neuroimaging study elucidated the neural basis of acupuncture in chronic sciatica. Neurological indicators and clinical measurements could be used as potential predictors of acupuncture response. This study combines neuroimaging and artificial intelligence techniques to highlight the potential of acupuncture for the treatment of chronic neuropathic pain.

ABSTRACT
PURPOSE: Knee osteoarthritis (KOA) is a common disorder among middle and older individuals. Electroacupuncture and exercise are present as two popular physical therapies for the management of KOA, and both were demonstrated to produce considerable results. However, the clinical decision-making process between these therapeutic interventions remains challenging due to the limited evidence of distinctions in their respective effects. This study aims to evaluate the clinical effect and cost effectiveness of electroacupuncture versus exercise in patients with KOA. STUDY DESIGN AND METHODS: This is a randomized controlled trial in which 196 symptomatic KOA patients will be randomly assigned 1:1 either to the electroacupuncture group (n = 98) and the exercise group (n = 98). Patients in the electroacupuncture group will receive acupuncture with electric stimulation 3 times a week for 8 weeks, whereas patients in the exercise group will receive neuromuscular training twice a week for 8 weeks. Education concerning KOA management will be provided in both therapies. Co-primary outcomes include changes in numerical rating scale (NRS) and Knee injury and Osteoarthritis Outcome Score (KOOS) Activities of Daily Living (ADL) subscale from baseline at week 8. Secondary outcomes include KOOS Pain subscale, KOOS knee-related Quality of Life (QOL) subscale, Short Form 6 Dimensions (SF-6D), five-level EuroQol five-dimensional questionnaire (EQ-5D-5L), Credibility/ Expectancy Questionnaire, Patient's global assessment (PGA), 30-second Chair Stand Test (30s-CST), 40m (4*10m) Fast Paced Walk Test (40m FPWT), and Daily Physical Activity level (DPA). DISCUSSION: The results of this study will provide evidence regarding differences between these 2 physical therapies in multiple aspects and will provide specific guidance for the development of treatments based on the needs of individual patients.

OBJECTIVE: Converging evidence indicates that subjective cognitive decline (SCD) could be an early indicator of dementia. The hippocampus is the earliest affected region during the progression of cognitive impairment. However, little is known about whether and how acupuncture change the hippocampal structure and function of SCD individuals. METHODS: Here, we used multi-modal MRI to reveal the mechanism of acupuncture in treating SCD. Seventy-two older participants were randomized into acupuncture or sham acupuncture group and treated for 12 weeks. RESULTS: At the end of the intervention, compared to sham acupuncture, participants with acupuncture treatment showed improvement in composite Z score from multi-domain neuropsychological tests, as well as increased hippocampal volume and functional connectivity. Moreover, the greater white matter integrity of the fornix, which is the major output tract of the hippocampus, was shown in the acupuncture group. CONCLUSION: These findings suggest that acupuncture may improve the cognitive function of SCD individuals, and increase hippocampal volume on the regional level and enhance the structural and functional connectivity of hippocampus on the connective level.

PURPOSE: Acupuncture has been widely used in the treatment of knee osteoarthritis (KOA), but the selection of acupoints is indeterminate and lacks biological basis. The skin temperature of acupoints can reflect the state of local tissue and may be a potential factor for guiding acupoint selection. This study aims to compare the skin temperature of acupoints between KOA patients and the healthy population. STUDY DESIGN AND METHODS: This is a protocol for a cross-sectional case-control study with 170 KOA patients and 170 age- and gender-matched healthy individuals. Diagnosed patients aged 45 to 70 will be recruited in the KOA group. Participants in the healthy group will be matched with the KOA group based on mean age and gender distribution. Skin temperature of 11 acupoints (ST35, EX-LE5, GB33, GB34, EX-LE2, ST34, ST36, GB39, BL40, SP9, SP10) will be extracted from infrared thermography (IRT) images of the lower limbs. Other measurements will include demographic data (gender, age, ethnicity, education, height, weight, BMI) and disease-related data (numerical rating scale, pain sites, duration of pain, pain descriptors, pain activities). DISCUSSION: The results of this study will provide biological evidence for acupoint selection. This study is a precondition for follow-up studies, in which the value of optimized acupoint selection will be verified. TRIAL REGISTRATION: ChiCTR2200058867.

ABSTRACT: Chronic pain has been one of the leading causes of disability. Acupuncture is globally used in chronic pain management. However, the efficacy of acupuncture treatment varies across patients. Identifying individual factors and developing approaches that predict medical benefits may promise important scientific and clinical applications. Here, we investigated the psychological and neurological factors collected before treatment that would determine acupuncture efficacy in knee osteoarthritis. In this neuroimaging-based randomized controlled trial, 52 patients completed a baseline assessment, 4-week acupuncture or sham-acupuncture treatment, and an assessment after treatment. The patients, magnetic resonance imaging operators, and outcome evaluators were blinded to treatment group assignment. First, we found that patients receiving acupuncture treatment showed larger pain intensity improvements compared with patients in the sham-acupuncture arm. Second, positive expectation, extraversion, and emotional attention were correlated with the magnitude of clinical improvements in the acupuncture group. Third, the identified neurological metrics encompassed striatal volumes, posterior cingulate cortex (PCC) cortical thickness, PCC/precuneus fractional amplitude of low-frequency fluctuation (fALFF), striatal fALFF, and graph-based small-worldness of the default mode network and striatum. Specifically, functional metrics predisposing patients to acupuncture improvement changed as a consequence of acupuncture treatment, whereas structural metrics remained stable. Furthermore, support vector machine models applied to the questionnaire and brain features could jointly predict acupuncture improvement with an accuracy of 81.48%. Besides, the correlations and models were not significant in the sham-acupuncture group. These results demonstrate the specific psychological, brain functional, and structural predictors of acupuncture improvement and may offer opportunities to aid clinical practices.

Importance: Renal colic is described as one of the worst types of pain, and effective analgesia in the shortest possible time is of paramount importance. Objectives: To examine whether acupuncture, as an adjunctive therapy to analgesics, could accelerate pain relief in patients with acute renal colic. Design, Setting, and Participants: This single-center, sham-controlled, randomized clinical trial was conducted in an emergency department in China between March 2020 and September 2020. Participants with acute renal colic (visual analog scale [VAS] score ≥4) due to urolithiasis were recruited. Data were analyzed from October 2020 to January 2022. Interventions: After diagnosis and randomization, all patients received 50 mg/2 mL of diclofenac sodium intramuscular injection immediately followed by 30-minute acupuncture or sham acupuncture. Main Outcomes and Measures: The primary outcome was the response rate at 10 minutes after needle manipulation, which was defined as the proportion of participants whose VAS score decreased by at least 50% from baseline. Secondary outcomes included response rates at 0, 5, 15, 20, 30, 45, and 60 minutes, rescue analgesia, and adverse events. Results: A total of 115 participants were screened and 80 participants (66 men [82.5%]; mean [SD] age, 45.8 [13.8] years) were enrolled, consisting of 40 per group. The response rates at 10 minutes were 77.5% (31 of 40) and 10.0% (4 of 40) in the acupuncture and sham acupuncture groups, respectively. The between-group differences were 67.5% (95% CI, 51.5% to 83.4%; P < .001). The response rates of acupuncture were also significantly higher than sham acupuncture at 0, 5, 15, 20 and 30 minutes, whereas no significant difference was detected at 45 and 60 minutes. However, there was no difference between the 2 groups in rescue analgesia rate (difference 2.5%; 95% CI -8.8% to 13.2%; P > .99). No adverse events occurred during the trial. Conclusions and Relevance: These findings suggest that acupuncture plus intramuscular injection of diclofenac is safe and provides fast and substantial pain relief for patients with renal colic compared with sham acupuncture in the emergency setting. However, no difference in rescue analgesia was found, possibly because of the ceiling effect caused by subsequent but robust analgesia of diclofenac. Acupuncture can be considered an optional adjunctive therapy in relieving acute renal colic. Trial Registration: Chinese Clinical Trial Registry: ChiCTR1900025202.

INTRODUCTION: Hypertension is a common risk factor for cardiovascular disease. Transcutaneous electrical acupoint stimulation (TEAS) may be effective for hypertension, but the evidence remains limited. The aim of this study is to evaluate the effectiveness and safety of the smart phone-based TEAS as adjunctive therapy for hypertension. METHODS AND ANALYSIS: This study is a 52-week cluster randomised controlled trial with 1600 hypertension patients in 32 community health service centres. Patients who meet the inclusion criteria will be randomised into usual care group or TEAS group in a 1:1 ratio. All patients will be provided with usual care as recommended by the guidelines. In addition to this, patients in the TEAS group will receive non-invasive acupoint electrical stimulation for 30 min at home, 4 times weekly for 12 weeks. The primary outcome will be the mean difference in the changes in office systolic blood pressure from baseline to 12 weeks between TEAS and usual care groups. Secondary outcomes will include the change of mean diastolic blood pressure, proportion of patients with controlled blood pressure (blood pressure <140/90 mm Hg), proportion of patients taking antihypertensive drugs, change in number of antihypertensive drugs and changes in 12-item Short-Form. Tertiary outcomes will include change in body mass index, change in waist circumference, physical activity and medication adherence. Safety outcomes will be any serious adverse events and clinical events. ETHICS AND DISSEMINATION: This study has been approved by ethics committee of Beijing University of Chinese Medicine (No. 2020BZHYLL0104). Written informed consent will be obtained from all patients before randomisation. Trial results will be disseminated in peer-reviewed publications. TRIAL REGISTRATION NUMBER: ChiCTR2000039400.

The authors investigated the effectiveness of home-based transcutaneous electrical acupoint stimulation (TEAS) combined with lifestyle modification on blood pressure (BP) control and explored the feasibility of the trial design in this prospective, randomized controlled trial. The authors recruited individuals with high-normal BP who had a systolic blood pressure (SBP) of 120-139 mm Hg and a diastolic blood pressure (DBP) of 80-89 mm Hg, or both. Participants were randomly assigned to receive either lifestyle modification combined with TEAS four times weekly for 12 weeks at home (intervention group) or solely lifestyle modification (control group). The primary outcome was the change in mean SBP at week 12 from the baseline measurement. A total of 60 participants were randomized in a 1:1 ratio, and an intention-to-treat analysis was performed on all of the outcomes. The mean difference in the change in SBP for the intervention group (compared to the control) at week 12 was -3.85 mm Hg (95% CI: -7.58 to -.12; p = .043); for the DBP, the change was -2.27 mm Hg (95% CI: -5.76 to 1.23; p = .199). There was no difference in the proportion of progression to hypertension, quality of life, body mass index (BMI) or waist circumference. In addition, two participants reported TEAS-related adverse events. The authors found a reduction in SBP control in the pragmatic, home-based intervention by using TEAS combined with lifestyle modification in adults with high-normal BP. Trial Registration: The study was registered in the Chinese Clinical Trial Registry (ChiCTR 1900024982) on August 6, 2019.

Background: Postoperative ileus after colorectal surgery is a frequent problem that significantly delays recovery, increases perioperative costs, and negatively impacts on daily life, physical and psychosocial functioning, and wellbeing. We investigated the effect of acupuncture at different single acupoint combined with standard care on postoperative ileus. Methods: In this single-centre, three-arm, prospective, randomised trial, we enrolled patients with primary colorectal cancer undergoing elective colorectal resection at Cancer Hospital Chinese Academy of Medical Science in Beijing, China. Patients were randomly assigned (1:1:1) to receive either electroacupuncture (EA) at ST36 or ST25 combined with standard care (two EA groups) once daily from post-operative days 1-4, or standard care alone (standard care group). The co-primary outcomes were time to first flatus and time to defecation assessed in the intention-to-treat population. This study is registered with Chictr.org.cn, ChiCTR1900027466. Finding: Between Nov 15, 2019, and Sep 30, 2020, 129 patients were assessed for eligibility, 105 patients (35 patients per group) were enrolled and included in the intention-to-treat analysis. After receiving EA at ST36, the time to first flatus and defecation were shorter (between-group difference -10.98 [97.5% CI -21.41 to -0.56], p = 0·02 for flatus; -25.41 [-47.89 to -2.93], p = 0·02 for defecation). However, we did not observe a significant difference in time to first flatus and defecation between the EA at ST25 group and standard care group (between-group difference -5.54 [97.5% CI -15.78 to 4.70], p = 0·26 for flatus; -17.69 [-40.33 to 4.95], p = 0·08 for defecation). There were no serious adverse events. Interpretation: Compared with standard care alone, standard care combined with EA at ST36, but not ST25, significantly enhances bowel function recovery in a postoperative setting to patients with colorectal cancer with laparoscopic elective colorectal resection.

ABSTRACT
BACKGROUND: Chronic Sciatica is a disabling condition causing considerable medical, social and financial implications. Currently, there is no recognised long-term effective treatment to alleviate sciatica. Acupuncture has been widely used for treating chronic pains with persistent analgesic effects. We aim to evaluate the efficacy and safety of acupuncture for chronic sciatica with follow-up in 52 weeks. METHODS AND ANALYSIS: This is a multicenter randomised sham-controlled trial. A total of 216 patients with chronic sciatica will be enrolled and randomly assigned to the acupuncture or sham acupuncture group. There will be 10 treatment sessions applied in 4 weeks with frequency decreased over time. Patients will complete follow-ups during 52 weeks. The primary outcomes are changes in leg pain intensity and disability from baseline to week 4. Secondary outcomes include back pain intensity, frequency and bothersomeness, quality of life, and global perceived effect. Adverse events will be recorded in detail. ETHICS AND DISSEMINATION: Ethical approval of this trial was granted from the ethics committee of Beijing University of Chinese Medicine and all study centres (No. 2020BZYLL0803). Written informed consent will be obtained from enrolled patients. Trial results will be disseminated in peer-reviewed publications.

PURPOSE: Activation of muscarinic receptors located in bladder sensory pathways is generally considered to be the primary contributor for driving the pathogenesis of neurogenic detrusor overactivity following spinal cord injury. The present study is undertaken to examine whether moxibustion improves neurogenic detrusor overactivity via modulating the abnormal muscarinic receptor pathway. MATERIALS AND METHODS: Female Sprague-Dawley rats were subjected to spinal cord injury with T9-10 spinal cord transection. Fourteen days later, animals were received moxibustion treatment for one week. Urodynamic parameters and pelvic afferents discharge were measured. Adenosine triphosphate (ATP) content in the voided cystometry fluid was determined. Expressions of M2, M3, and P2X3 receptors in the bladder mucosa were evaluated. RESULTS: Moxibustion treatment prevented the development of detrusor overactivity in spinal cord injury rats, with an increase in the intercontraction interval and micturition pressure threshold and a decrease in afferent activity during filling. The expression of M2 was markedly suppressed by moxibustion, accompanied by a reduction in the levels of ATP and P2X3. M2 receptor antagonist methoctramine hemihydrate had similar effects to moxibustion on bladder function and afferent activity, while the M2-preferential agonist oxotremorine methiodide abolished the beneficial effects of moxibustion. CONCLUSION: Moxibustion is a potential candidate for treating neurogenic bladder overactivity in a rat model of spinal cord injury, possibly through inhibiting the M2/ATP/P2X3 pathway.

Metabolic syndrome (MS) is a clinical syndrome with multiple metabolic disorders. As the diagnostic criteria for MS still lacking of imaging laboratory method, this study aimed to explore the differences between healthy people and MS patients through infrared thermography (IRT). However, the observation region of the IRT image is uncertain, and the research tried to solve this problem with the help of knowledge mining technology. 43 MS participants were randomly included through a cross-sectional method, and 43 healthy participants were recruited through number matching. The IRT image of each participant was segmented into the region of interest (ROI) through the preprocessing method proposed in this research, and then the ROI features were granulated by the K-means algorithm to generate the formal background, and finally, the two formal background were separately built into a knowledge graph through the knowledge mining method based on the attribute partial order structure. The baseline data shows that there is no difference in age, gender, and height between the two groups (P > 0.05). The image preprocessing method can segment the IRT image into 18 ROI. Through the K-means method, each group of data can be separately established with a 43 × 36 formal background and generated a knowledge graph. It can be found through knowledge mining and independent-samples T test that the average temperature and maximum temperature difference between the chest and face of the two groups are statistically different (P < 0.01). IRT could reflect the difference between healthy people and MS people. The measurement regions were found by the method of knowledge mining on the premise of unknown. The method proposed in this paper may add a new imaging method for MS laboratory examinations, and at the same time, through knowledge mining, it can also expand a new idea for clinical research of IRT.

In order to explore the application of "patient and public involvement" (PPI) in acupuncture clinical research, the connotation, reporting standards and research status of PPI at home and abroad are collated, and the key problems of PPI encountered in acupuncture clinical research are deeply considered and summarized. It is suggested that the short-form checklist of the Guidance for Reporting Involvement of Patients and the Public (GRIPP) of the 2nd edition should be applied to acupuncture clinical research. PPI provides a new perspective for acupuncture clinical research. It is beneficial for each stage of research, contributes to the improvement of acupuncture medical service mode and increases the success rate and cost-effectiveness of research so that the innovation and development of acupuncture science can be promoted.

BACKGROUND: Current evidence suggests that acupuncture is an effective adjunctive therapy that can bring potential benefits to patients with cardiac arrhythmias. However, there are relevant gaps in the optimal therapeutic strategy, which may cause uncertainties on the best practice of acupuncture treatment for arrhythmia. We aim to develop consensus-based recommendations for clinical guidance on acupuncture treatment of cardiac arrhythmias. METHODS: A multidisciplinary panel of specialists was invited to participate in a two-round semi-open clinical issue investigation. Meanwhile, relevant literature reviews were searched in 3 databases to provide evidence. Subsequently, an initial consensus voting list on acupuncture as an adjunctive therapy for cardiac arrhythmias was derived from the clinical investigation and literature review. Finally, 30 authoritative experts reached a consensus on the key issues of the voting list by a three-round modified Delphi survey. Consensus was defined when >80% agreement was achieved. RESULTS: Following the three-round Delphi survey, there were 32 items (91.43%) finally reaching consensus, including the following 5 domains: (I) the benefits of acupuncture for the appropriate population; (II) the general therapeutic principle; (III) the acupuncture strategy; (IV) the relevant adverse events; (V) others. CONCLUSIONS: Consensus was achieved on some key elements. Given the lack of guidelines and the substantial heterogeneity of previous studies, these recommendations are of value in providing guidance for clinical practice of acupuncturists and in assisting patients with arrhythmia to obtain standardized acupuncture treatment. It also pointed out some problems that need to be carefully explored in future studies.
ABSTRACT
BACKGROUND: Constipation is known as a common adverse effect of antipsychotics. Advice for its management remains inadequate. This study is designed to investigate the efficacy and safety of electro-acupuncture (EA) for antipsychotic-related constipation. METHODS: This is a single-centric, parallel-group, randomized controlled trial with blinded participants, outcome assessor, and statistician. One hundred twelve participants will be randomly assigned into the EA group or sham acupuncture (SA) group in a 1:1 ratio. The study will last for 22 weeks for each participant, including a 2-week baseline assessment period, an 8-week treatment period, and a follow-up for 12 weeks. The primary outcome is the change of mean weekly complete spontaneous bowel movements (CSBMs) during weeks 1 to 8 from baseline. Secondary outcomes include the change from baseline of mean weekly CSBMs during the follow-up period, mean weekly spontaneous bowel movements (SBMs), overall CSBM response rate, scores on Bristol Stool Form Scale (BSFS), straining level, Patient Assessment of Constipation Symptoms (PAC-SYM), Patient Assessment of Constipation Quality of life questionnaire (PAC-QOL), and Brief Psychiatric Rating Scale (BPRS). Adverse events and medicine use will be recorded as well. DISCUSSION: The study is designed based on a rigorous methodology to evaluate the efficacy and safety of EA for antipsychotic-related constipation. The finding will be published in peer-reviewed journals as reliable evidence. TRIAL REGISTRATION: ClinicalTrials.gov ChiCTR2000032582.

A close relationship between knee osteoarthritis (KOA) and gut microbiota has recently been described. Herein, we aim to investigate the effect of electroacupuncture (EA) on gut microbiota in participants with KOA. We conducted a study of 60 participants with KOA and 30 matched healthy controls (HCs). Sixty participants were allocated to either EA group (n=30) or sham acupuncture (SA) group (n=30). Five obligatory acupoints and three adjunct acupoints were punctured in the EA group. Eight non-acupoints that were separated from conventional acupoints or meridians were used for the SA group. Participants in both groups received 24 sessions within eight weeks. Fecal microbial analyses by 16S ribosomal RNA gene sequencing were carried out after collecting stools at T0 and T8 weeks (Four samples with changed defecation habits were excluded). The results showed that both Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score (P=0.043) and NRS score (P=0.002) decreased more in EA group than those in SA group. Moreover, EA could reverse more KOA-related bacteria including Bacteroides, [Eubacterium]_hallii_group, Agathobacter and Streptococcus. The number of significantly different genera between KOA patients and HCs were less after EA treatment than that after SA treatment. This meant that EA modified the composition of the gut microbiome, making it closer to healthy people, while not significantly affecting the microbial diversity. Two genera including Agathobacter (P=0.0163), Lachnoclostridium (P=0.0144) were statistically increased than baseline in EA group (paired Wilcoxon rank sum test). After EA treatment, Bacteroides (P=0.0394) was more abundant and Streptococcus (P=0.0306) was significantly reduced in patients who demonstrated adequate response than in those with inadequate response (Wilcoxon rank-sum test). Spearman correlation test between gut microbe and KOA clinical outcomes indicated that Bacteroides and Agathobacter was negatively correlated with NRS score, WOMAC total score, and WOMAC pain, stiffness and pain scores (P<0.001 or 0.05 or 0.01), while Streptococcus was positively correlated with them (P<0.05 or 0.01). Our study suggests that EA contributes to the improvement of KOA and gut microbiota could be a potential therapeutic target.
