Abstract
Rheumatoid arthritis (RA) involves chronic joint inflammation. Combining acupuncture and medication for RA treatment faces challenges like spatiotemporal variability, limited drug loading in acupuncture needles, and premature or untargeted drug release. Here, we designed a new type of tubular acupuncture needles, with an etched hollow honeycomb-like structure to enable the high loading of therapeutics, integrating the traditional acupuncture and drug repository into an all-in-one therapeutic platform. In these proof-of-concept experiments, we fabricated injectable hollow honeycomb electroacupuncture needles (HC-EA) loaded with melittin hydrogel (MLT-Gel), enabling the combination treatment of acupuncture stimulation and melittin therapy in a spatiotemporally synchronous manner. Since the RA microenvironment is mildly acidic, the acid-responsive chitosan (CS)/sodium beta-glycerophosphate (β-GP)/ hyaluronic acid (HA) composited hydrogel (CS/GP/HA) was utilized to perform acupuncture stimulation and achieve the targeted release of injected therapeutics into the specific lesion site. Testing our therapeutic platform involved a mouse model of RA and bioinformatics analysis. MLT-Gel@HC-EA treatment restored Th17/Treg-mediated immunity balance, reduced inflammatory factor release (TNF-α, IL-6, IL-1β), and alleviated inflammation at the lesion site. This novel combination of modified acupuncture needle and medication, specifically melittin hydrogel, holds promise as a therapeutic strategy for RA treatment.

Rao Y, Ge L, Wu J. A systematic review and coordinate-based meta-analysis of fMRI studies on acupuncture at LR 3. Front Neurosci 2024; 18:1341567. [PMID: 38348133 PMCID: PMC10859399 DOI: 10.3389/fnins.2024.1341567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Accepted: 01/03/2024] [Indexed: 02/15/2024] Open
Abstract
Objectives The acupoint LR3 (Taichong) is frequently utilized in clinical acupuncture. However, its underlying neural mechanisms remain not fully elucidated, with speculations suggesting its close association with specific brain activity patterns. Methods A comprehensive literature search was undertaken across several online databases, such as PubMed, Web of Science, Embase, Cochrane Library, CNKI (China National Knowledge Infrastructure), Wanfang Database, VIP Database, and the Chinese Biomedical Database. Two independent researchers handled the study selection, quality assessment, and data extraction processes. Using the seed-based d-mapping meta-analysis approach, we evaluated the brain regions activated by LR3 acupuncture in healthy subjects. Subsequent subgroup analysis was stratified by fMRI types, and regression analyses were performed considering the duration of acupuncture, depth of needle insertion, and needle diameter. The identified active brain regions were then intricately projected onto large-scale functional networks. Results A total of 10 studies met the criteria for inclusion, encompassing 319 healthy right-handed participants. The meta-analysis indicates that acupuncture at the LR3 activates regions such as the right postcentral gyrus, left thalamus, left middle frontal gyrus, and right superior frontal gyrus. Additionally, meta-regression analysis highlights that increased acupuncture duration correlates with progressively intensified activation of the right superior frontal gyrus. Subgroup analysis posits that variations in the type of fMRI employed might account for heterogeneity in the pooled results. Concurrently, functional network analysis identifies the primary activated regions as aligning with the Basal ganglia network, Auditory network, Left executive control network, Posterior salience network, Right executive control network, and Sensorimotor networks. Conclusion Acupuncture at the LR3 in healthy subjects selectively activates brain regions linked to pain perception, emotional processing, and linguistic functions. Extending the needle retention duration intensifies the activation of the right superior frontal gyrus. These findings enrich our comprehension of the neurobiological underpinnings of acupuncture's role in pain mitigation and emotional regulation.

Abstract
BACKGROUND To assess the effect of acupoint stimulation for Alcohol use disorders (AUD). METHODS AUD is a complex disease that threatens the health of the global population. Acupoint stimulation, a sort of therapy applying stimulation on acupoints to produce a therapeutic effect without side effects, has been widely used in AUD patients, but its efficacy remains controversial. Electronic databases (the Cochrane Library, EMBASE, PubMed, CNKI, VIP, Wan-Fang) were systematically searched for randomized controlled trials (RCTs) on acupoint stimulation for AUD from database inception to September 30, 2022. A meta-analysis was performed using Review Manager 5.4 software. Continuous data (scales) were expressed as mean differences (MDs) or standardized mean difference (SMD) with 95% confidence intervals (95% CI). Study methodological quality was assessed according to the Cochrane risk-of-bias tool for trials. The grading of recommendations assessment, development and evaluation was used to assess the certainty of evidence for outcomes. RESULTS A total of 16 RCTs with 1097 participants were included. Compared to psychotherapy or drug therapy alone, the combination of acupoint stimulation and other sorts of therapies presented advantages in alleviating alcohol craving (SMD = -1.09, 95% CI = -1.40 to -0.77, df = 2, P < .00001, grading of recommendations assessment, development and evaluation very low certainty), (SMD = -2.25, 95% CI = -3.17 to -1.34, df = 3, P < .00001, low certainty) and the severity of alcohol withdrawal symptoms (MD = -1.21, 95% CI = -2.32 to -0.1, df = 2, P = .03, low certainty), as well as improving anxiety (MD = -3.41, 95% CI = -4.06 to -2.76, df = 4, P < .00001, very low certainty) and depression levels (MD = -3.27, 95% CI = -4.92 to -1.62, df = 4, P = .0001, very low certainty) on patients with AUD. In addition, a greater effect was also found with the 4-week treatment courses in reducing craving (SMD = -2.18, 95% CI = -2.61 to -1.75, P < .00001, low certainty). CONCLUSION Acupoint stimulation and its combined therapy may better relieve AUD symptoms effectively and the treatment duration should be set at more than 2 weeks. However, due to the low-quality of the included RCTs, high-quality studies are needed to further confirm it in the future.

Abstract
Auriculotherapy has been used to reduce withdrawal symptoms during drug detoxication. The purpose of this study was to review the results of the randomized controlled trials (RCTs) that examined the impact of auriculotherapy on addiction. This study aimed to find an effective protocol involving auricular acupuncture points, intervention duration and frequency, and stimulating methods. We searched PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Medline for articles published between January 1, 1994, and March 31, 2021. The keywords used were auricular, acupuncture, addiction, substance misuse, smoking, randomized controlled trial, clinical trial, and human. Each RCT was evaluated for quality applying the risk of bias tool by the Cochrane group. Effect size (Hedges's g) was calculated using the mean values and standard deviation of the experimental and control groups. The risk for bias of these studies was moderate to high and only four studies (11.1%) earned scores of 6, indicating the lowest risk of bias and highest quality RCT. Out of 36 studies, 23 (64%) reported that auriculotherapy was effective for treating addiction such as opioids, cocaine, alcohol, heroin, nicotine, and gambling. The most commonly used combination of acupuncture points (four of 36 studies) was shenmen, sympathetic, liver, lung, and kidney, which are called NADA protocol. The following most frequently used combination of acupressure points (four out of 36 studies) was shenmen, subcortex, heart, lung, and liver. Acupressure could be considered to be used for the treatment of addiction.

Clinical and Economic Evaluation of Acupuncture for Opioid-Dependent Patients Receiving Methadone Maintenance Treatment: The Integrative Clinical Trial and Evidence-Based Data. Front Public Health 2021; 9:689753. [PMID: 34485219 PMCID: PMC8415360 DOI: 10.3389/fpubh.2021.689753] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 06/15/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: From the health care and societal perspectives, this study aimed to evaluate the clinical and economic effects of acupuncture as an adjunctive therapy for patients receiving methadone maintenance treatment (MMT). Methods: We conducted a parallel-arm RCT in China in 2019. Patients were included who met the diagnostic criteria and receive MMT for more than 30 days. Patients were randomly assigned to the exposed group (acupuncture plus MMT) or control group (MMT) at a 1:1 ratio. Daily methadone dosage, drug cravings using the VAS score, and insomnia using the Pittsburgh Sleep Quality Index (PSQI) were chosen as the effectiveness indexes, and the quality-adjusted life years (QALYs) was chosen as the utility index. Results: Overall, 123 patients were included. The exposed group was significantly (P < 0.05) better than the control group in the improvement of daily methadone dosage (17.68 vs. 1.07), VAS (38.27 vs. 2.64), and PSQI (2.18 vs. 0.30). The QALY was 0.0784 (95%CI: 0.0761-0.0808) for the exposed group and 0.0762 (95%CI: 0.0738-0.0787) for the control group. The total cost of the exposed group (2869.50 CNY) was higher than the control group (2186.04 CNY). The ICER of daily methadone dosage (41.15), VAS (17.86), and PSQI (313.51) were shown to be economically efficient. While ICUR (310,663.64 CNY/QYLY) was higher than the cost suggested by WHO. Conclusion: Acupuncture as an adjuvant therapy for MMT patients realizes its cost-effectiveness by reducing the dosage of methadone, improving drug cravings, and alleviating insomnia. It helps to improve quality of life, but since its cost exceeds what society is willing to pay, further study is needed.
