The objective of this study was to examine articles on acupuncture from past to present, revealing prevalent research trends, showcasing global productivity, identifying international collaborations, and highlighting influential publications and journals in the field. We acquired a comprehensive dataset comprising 9340 articles pertaining to acupuncture that were published within the time frame spanning from 1980 to 2023. These articles were sourced from the Web of Science and underwent rigorous analysis through a diverse set of bibliometric techniques. Our analytical approaches encompassed trend keyword analysis, thematic evolution analysis, conceptual structure analysis, factor analysis, citation and co-citation analyses, as well as an exploration of international collaboration patterns. The 3 most productive countries were China (n = 3357), the USA (n = 1351), and South Korea (n = 814). The 3 most productive journals were Acupuncture in Medicine (n = 440), Evidence Based Complementary and Alternative Medicine (n = 415), and Medical Acupuncture (n = 400). The 3 journals with the highest h-index on acupuncture were the Journal of Alternative and Complementary Medicine (h = 45), Pain (h = 41), and the American Journal of Chinese Medicine (h = 35). The most active author was Park Hi-Joon (n = 128). According to the findings of the factor analysis, acupuncture literature was grouped around 3 main subfactors. The primary factor encompassed topics related to the effectiveness/applicability of the treatment method for various medical conditions and general principles of acupuncture methods and points. The second factor covered topics related to mental health and quality of life. The third subfactor addressed the qualitative and quantitative analysis direction of acupuncture, such as meta-analysis and systematic reviews, and randomized controlled trials. From the past to the present, the most extensively researched main topics in acupuncture literature have covered a wide range of subjects. Prominent themes among these topics included acupuncture methods and applications, pain management, the nervous system and acupuncture, mental health and acupuncture, quality of life, and general health. In recent years, emerging trends in acupuncture research have focused on neurological health issues, oncology and cancer treatment, women\'s health and hormonal issues, sleep problems, digestive issues, and studies related to the quantitative and qualitative evaluation of acupuncture research.

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.

In acupuncture diagnosis and treatment, non-quantitative clinical descriptions have limited the development of standardized treatment methods. This study explores the effectiveness and the reasons for discrepancies in the entity recognition and classification of meridians in acupuncture indication using the Acupuncture Bidirectional Encoder Representations from Transformers (ACUBERT) model. During the research process, we selected 54 593 different entities from 82 acupuncture medical books as the pretraining corpus for medical literature, conducting classification research on Chinese medical literature using the BERT model. Additionally, we employed the support vector machine and Random Forest models as comparative benchmarks and optimized them through parameter tuning, ultimately leading to the development of the ACUBERT model. The results show that the ACUBERT model outperforms other baseline models in classification effectiveness, achieving the best performance at Epoch = 5. The model\'s \"precision,\" \"recall,\" and F1 scores reached above 0.8. Moreover, our study has a unique feature: it trains the meridian differentiation model based on the eight principles of differentiation and zang-fu differentiation as foundational labels. It establishes an acupuncture-indication knowledge base (ACU-IKD) and ACUBERT model with traditional Chinese medicine characteristics. In summary, the ACUBERT model significantly enhances the classification effectiveness of meridian attribution in the acupuncture indication database and also demonstrates the classification advantages of deep learning methods based on BERT in multi-category, large-scale training sets.

Migraine is a ubiquitous neurological disorder that affects approximately 1 billion people worldwide. Migraine is the second leading cause of illness in people of all ages worldwide. Uncertainty in migraine diagnosis leads to unnecessary testing and increases the treatment costs. To date, the pathogenesis of migraine is not fully understood, but it is generally believed that migraine involves the trigeminal nerve and its axonal projections to intracranial blood vessels. Pain signals from the trigeminal neurovascular system are transmitted to the brain, resulting in migraines. As an important component of complementary and alternative medicine, traditional Chinese medicine (TCM) has shown significant efficacy in the treatment of migraine, and has attracted increasing attention worldwide. This review is based on the pathophysiology of migraines in modern medicine. To explore the comprehensive treatment of migraine using TCM, acupuncture, and various other TCM treatments.

Pharmacopuncture is a widely used Korean medicine treatment, but its usage patterns and associated factors remain unclear. This study aimed to explore factors related to the use of pharmacopuncture alongside acupuncture and investigate the associated medical cost burden in South Korea. We analyzed the 2019 Korea Health Panel Annual Data, focusing on adult outpatients who received acupuncture alone or both acupuncture and pharmacopuncture (PA). We employed individual-level and visit-level approaches, using chi-square tests, t-tests, and binary logistic regression for analysis. Among 1280 patients, 10% were PA users. Logistic regression showed that PA use was significantly associated with being aged 30 to 49 (odd ratio [OR] = 2.531; P = .009), having an education level of elementary school or lower (OR = 2.571; P = .011), and being in the 2nd (OR = 1.914; P = .041) or 3rd income percentile (OR = 1.925; P = .020). Of 13,101 medical visits, 5.80% involved PA, with PA visits incurring significantly higher costs than acupuncture only visits (KRW 4438.33 vs 14,700.16; P < .001). Arthritis, shoulder disorders, and other joint conditions were more prevalent among PA visits (P < .001). This study reveals socioeconomic factors influencing pharmacopuncture use and highlights potential health inequalities in its access in South Korea. The higher costs associated with PA visits suggest a need for considering its inclusion in health insurance coverage. Future research should focus on the effectiveness, cost-effectiveness, and standardization of pharmacopuncture to address unmet healthcare needs and inform policy decisions.

BACKGROUND: Osteoporotic vertebral compression fracture (OVCF) is a common complication in elderly patients with osteoporosis. Despite undergoing percutaneous kyphoplasty (PKP) treatment, a significant percentage of OVCF patients (1.8% to 31.9%) continue to experience residual low back pain. While acupuncture has shown promise in relieving this pain, there is currently no systematic review on its efficacy specifically for residual low back pain after PKP in OVCF patients. This project aims to evaluate the effectiveness and safety of acupuncture as a treatment for this condition.
METHODS: A comprehensive search will be conducted, including manual and electronic searches of literature published. Various databases such as MEDLINE, PubMed, EMBASE, Web of Science, Cochrane Library, International Clinical Trial Registration Platform, China National Knowledge Network, China Biomedical Literature Database, China Scientific Journal Database and Wan-fang Database will be explored. Additional sources like bibliographies and meeting minutes will also be searched. All randomised controlled clinical trials related to acupuncture for treating residual low back pain after PKP in OVCF patients will be included. Two researchers will independently perform study selection, data extraction and quality assessment. The primary outcome measure will be pain relief assessed using a visual analogue scale (VAS) or other validated scales. Secondary outcomes include effectiveness, Oswestry dysfunction index (ODI), quality of life questionnaire (QUALEFFO-41), follow-up relapse rate and adverse events. If feasible, a meta-analysis using RevMan V.5.3 software will be conducted. Otherwise, descriptive or subgroup analyses will be performed. Database searches will commence after the publication of this agreement, with an estimated commencement date of 1 August 2024.
BACKGROUND: Ethical approval is not required since this review does not involve individual patient data. The findings will be disseminated through peer-reviewed journals or relevant conferences.
UNASSIGNED: CRD42023478838.

UNASSIGNED: Treating low back pain (LBP) often involves a combination of pharmacologic, nonpharmacologic, and interventional treatments; one approach is acupuncture therapy, which is safe, effective, and cost-effective. How acupuncture is used within pain care regimens for LBP has not been widely studied.
UNASSIGNED: To document trends in reimbursed acupuncture between 2010 and 2019 among a large sample of patients with LBP, focusing on demographic, socioeconomic, and clinical characteristics associated with acupuncture use and the nonpharmacologic, pharmacologic, and interventional treatments used by patients who utilize acupuncture.
UNASSIGNED: This cross-sectional study included insurance claims of US adults in a deidentified database. The study sample included patients diagnosed with LBP between 2010 and 2019. Data were analyzed between September 2023 and June 2024.
UNASSIGNED: Changes in rates of reimbursed acupuncture utilization between 2010 and 2019, including electroacupuncture use, which involves the electrical stimulation of acupuncture needles. Covariates included age, sex, race and ethnicity, income, educational attainment, region, and a chronic LBP indicator. Secondary analyses tracked other nonpharmacologic treatments (eg, physical therapy, chiropractic care), pharmacologic treatments (eg, opioids, gabapentinoids), and interventional treatments (eg, epidural steroid injections).
UNASSIGNED: The total sample included 6 840 497 adults with LBP (mean [SD] age, 54.6 [17.8] years; 3 916 766 female [57.3%]; 802 579 Hispanic [11.7%], 258 087 non-Hispanic Asian [3.8%], 804 975 non-Hispanic Black [11.8%], 4 974 856 non-Hispanic White [72.7%]). Overall, 106 485 (1.6%) had 1 or more acupuncture claim, while 61 503 (0.9%) had 1 or more electroacupuncture claim. The rate of acupuncture utilization increased consistently, from 0.9% in 2010 to 1.6% in 2019; electroacupuncture rates were relatively stable. Patients who were female (male: odds ratio [OR], 0.68; 99% CI, 0.67-0.70), Asian (OR, 3.26; 99% CI, 3.18-3.35), residing in the Pacific region (New England: OR, 0.26; 99% CI, 0.25-0.28), earning incomes of over $100 000 (incomes less than $40 000: OR, 0.59; 99% CI, 0.57-0.61), college educated (high school or less: OR, 0.32; 99% CI, 0.27-0.35), and with chronic LBP (OR, 2.39; 99% CI, 2.35-2.43) were more likely to utilize acupuncture. Acupuncture users were more likely to engage in other nonpharmacologic pain care like physical therapy (39.2%; 99% CI, 38.9%-39.5% vs 29.3%; 99% CI, 29.3%-29.3%) and less likely to utilize prescription drugs, including opioids (41.4%; 99% CI, 41.1%-41.8% vs 52.5%; 99% CI, 52.4%-52.5%), compared with nonusers.
UNASSIGNED: In this cross-sectional study, we found that acupuncture utilization among patients with LBP was rare but increased over time. Demographic, socioeconomic, and clinical characteristics were associated with acupuncture utilization, and acupuncture users were more likely to utilize other nonpharmacologic treatments and less likely to utilize pharmacologic treatments.

This study was conducted to examine the effects of acupuncture on gut microbiota and expression of NLRP3 inflammasome in the colon in poststroke depression (PSD) model rats. Sprague-Dawley male rats were randomized into four groups: sham surgery group, poststroke depression group, acupuncture group, and probiotics group. Acupuncture therapy at Baihui (GV20), Shenting (GV24), bilateral Zusanli (ST36) acupoints in the acupuncture group and probiotic gavage therapy in the probiotics group were performed once per day for 2 weeks. Behaviors of depression were assessed by using weight measurements, sucrose preference test, open field test, and forced swimming test. Histopathological alterations in the colon were determined by hematoxylin-eosin staining, the expression of NLRP3/ASC/caspase-1 pathway-related proteins was analyzed by western blotting. Serum levels of IL-1β and IL-18 were derived from ELISA. The 16S rRNA gene sequencing was performed to examine and analyze the differences of gut microbiota of rats among all groups. Acupuncture was effective to increase weight and ameliorate depressive-like behaviors in PSD rats. Acupuncture increased the diversity of gut microbiota, upregulated the abundance of Bifidobacteriaceae and Lactobacillaceae, and decreased the relative abundance of Peptostreptococcaceae, Rikenellaceae, Eggerthellaceae, and Streptococcaceae at family level. Acupuncture effectively improved the pathological changes in the colon. Meanwhile, acupuncture reduced NLRP3, ASC, caspase-1 protein expressions in the colon, and serum levels of IL-18 and IL-1β. Acupuncture may reduce depressive-like behaviors of PSD by regulating the gut microbiota and suppressing hyperactivation of NLRP3 inflammasome in the colon. Microbiota-gut-brain axis may be an effective target pathway for acupuncture treatment of PSD.

UNASSIGNED: Choledocholithiasis, or bile duct gallstones, is effectively treated with surgery, which does not prevent relapse. A common adjuvant therapy is the stimulation of the Yanglingquan point (GB34). Acupoint catgut embedding (ACE), an acupoint stimulation therapy, may be a better treatment for choledocholithiasis.
UNASSIGNED: To investigate the effect of ACE in stimulating GB34 on bile metabolism and its possible mechanism via metabonomics.
UNASSIGNED: In this study, we used ultrahigh performance liquid chromatographyquadrupole time-of-flight mass spectrometry (UHPLC-MS/MS) to analyze the changes in bile metabolites, metabolic pathways, and liver function indicators in 16 patients with choledocholithiasis before and after ACE stimulation.
UNASSIGNED: We identified 10 metabolites that exhibited significant differences in the bile before and after ACE, six of which significantly increased and four that significantly decreased. Moreover, six liver function indicators showed a downward trend. We identified related metabolic pathways as glycerophospholipid metabolism, steroid biosynthesis, and the citrate cycle (TCA cycle).
UNASSIGNED: This study shows that ACE stimulation of GB34 can effectively help treat choledocholithiasis, which may be clinically applicable to ACE.

Recently, several previously undiscussed concerns in acupuncture research have been brought to light. Among these, the core issue stems from the ambiguity surrounding the identity of acupoints. Hence, the question \"What is the identity of acupoints?\" remains of particular importance in acupuncture research. To answer this question, we reviewed the original concept of acupoints explained in Oriental medicine, from which acupuncture treatment originated, and examined scientific research on acupuncture and acupoints. We then proposed a perspective on the identity of acupoints and speculated about a possible reason for their elusive nature: qi, which congregates at and flows in and out of acupoints, might be bioelectricity, making these points inherently difficult to measure anatomically or histologically. Consequently, acupoints are suggested to be spaces where bioelectricity congregates, thus inevitably exhibiting electrical characteristics.
