Osteoarthritis (OA) is a highly prevalent joint disorder characterized by progressive degeneration of articular cartilage, subchondral bone remodeling, osteophyte formation, synovial inflammation, and meniscal damage. Although the etiology of OA is multifactorial, pro-inflammatory processes appear to play a key role in disease pathogenesis. Previous studies indicate that electroacupuncture (EA) exerts chondroprotective, anti-inflammatory, and analgesic effects in preclinical models of OA, but the mechanisms underlying these potential therapeutic benefits remain incompletely defined. This study aimed to investigate the effects of EA on OA development in a rat model, as well as to explore associated molecular mechanisms modulated by EA treatment. Forty rats were divided into OA, EA, antagomiR-214, and control groups. Following intra-articular injection of monosodium iodoacetate to induce OA, EA and antagomiR-214 groups received daily EA stimulation at acupoints around the knee joint for 21 days. Functional pain behaviors and chondrocyte apoptosis were assessed as outcome measures. The expression of microRNA-214 (miR-214) and its downstream targets involved in apoptosis and nociception, BAX and TRPV4, were examined. Results demonstrated that EA treatment upregulated miR-214 expression in OA knee cartilage. By suppressing pro-apoptotic BAX and pro-nociceptive TRPV4, this EA-induced miR-214 upregulation ameliorated articular pain and prevented chondrocyte apoptosis. These findings suggested that miR-214 plays a key role mediating EA's therapeutic effects in OA pathophysiology, and represents a promising OA treatment target for modulation by acupuncture.

ABSTRACT Background: The emergence of the Nerve Growth Factor (NGF) has promoted the development of neuroprotective therapy; however, it has little effect on cerebral ischemia because of its poor Blood-Brain Barrier (BBB) permeability. Specific Mode Electroacupuncture Stimulation (SMES) can open BBB safely and effectively; however, it has shown inconclusive clinical effects and indirect clinical evidence in the recovery phase. Hence, the authors conducted a multicentre, randomized, placebo-controlled, assessor-blinded clinical trial to assess the effectiveness and safety of SMES combined with NGF treatment used during ischaemic stroke recovery. Methods: A total of 288 stroke patients from three hospitals will be recruited and randomly allocated to four groups: acupuncture + placebo, acupuncture + NGF, SMES + placebo, and SMES + NGF, in a 1:1:1:1 ratio. Assessment data will be collected at baseline, 2-weeks, and 4-weeks during the treatment period, as well as at the 4-week and 8-week follow-up after treatment completion. The primary outcome measure will be the basic cure rate. The secondary outcome measures include the simplified Modified Barthel Index, Timed Up and Go Test, Fugl-Meyer Assessment of Motor Function Score, Tinetti Performance Oriented Mobility Assessment, Montreal Cognitive Assessment, and Loewenstein Occupational Therapy Cognitive Assessment. Moreover, resting-state functional magnetic resonance imaging and Functional near-infrared spectroscopy can detect changes in cerebral blood flow and brain function and investigate the relationship between the clinical efficacy and mechanism of the prescribed interventions. Conclusion: This study will provide clinical evidence for the efficacy and safety of SMES combined with NGF in the treatment of stroke patients.

ABSTRACT Introduction: Meniscal injury is a common condition that can lead to disability due to pain and proprioceptive failure, requiring immediate attention. Combination therapies involve advanced approaches aiming to accelerate rehabilitation in athletes, and electroacupuncture presents therapeutic benefits, although there is still no evidence of its combination with sports therapy. Objective: This paper analyzes the performance of sports rehabilitation in athletes with meniscal lesions using electroacupuncture combined with sports therapy. Methods: The intervention in the control group was based on a traditional range of motion work, muscle strength, proprioceptive training, and other exercise therapies, while the experimental group received a 30 min electro-acupuncture protocol three times a week for four consecutive weeks. The surrogate data (gender, age, disease course, location) are the same. Before treatment, joint activity, muscle strength, total joint scale score of the LYSHOLM questionnaire, and other observational indices were measured during the 6th and 12th week of treatment. The non-parametric statistical method and T-test were used to analyze the changes of each index before and after treatment. After 12 weeks of treatment, the difference between the experimental group and the combination before treatment was significant. Results: The treatment effect of the experimental group was significantly better than the control group. Conclusion: The effect of sports rehabilitation of athletes with meniscus injury based on electroacupuncture combined with sports therapy showed high resolutive application value, indicating an alternative for non-surgical treatment in knee meniscus injuries. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

Abstract Previous studies have shown that peripheral nerve injury can lead to abnormal dendritic spine remodeling in spinal dorsal horn neurons. Inhibition of abnormal dendritic spine remodeling can relieve neuropathic pain. Electroacupuncture (EA) has a beneficial effect on the treatment of neuropathic pain, but the specific mechanism remains unclear. Evidence has shown that slit-robo GTPase activating protein 3 (srGAP3) and Rho GTPase (Rac1) play very important roles in dendritic spine remodeling. Here, we used srGAP3 siRNA and Rac1 activator CN04 to confirm the relationship between SrGAP3 and Rac1 and their roles in improving neuropathic pain with EA. Spinal nerve ligation (SNL) was used as the experimental model, and thermal withdrawal latency (TWL), mechanical withdrawal threshold (MWT), Western blotting, immunohistochemistry and Golgi-Cox staining were used to examine changes in behavioral performance, protein expression and dendritic spines. More dendritic spines and higher expression levels of srGAP3 were found in the initial phase of neuropathic pain. During the maintenance phase, dendritic spines were more mature, which was consistent with lower expression levels of srGAP3 and higher expression levels of Rac1-GTP. EA during the maintenance phase reduced the density and maturity of dendritic spines of rats with SNL, increased the levels of srGAP3 and reduced the levels of Rac1-GTP, while srGAP3 siRNA and CN04 reversed the therapeutic effects of EA. These results suggest that dendritic spines have different manifestations in different stages of neuropathic pain and that EA may inhibit the abnormal dendritic spine remodeling by regulating the srGAP3/Rac1 signaling pathway to alleviate neuropathic pain.

ABSTRACT Introduction: The temporomandibular disorders constitute a painful condition that affects the mastication muscles, the temporomandibular joint, as well as several anatomical structures of the stomatognathic system. Objective: To evaluate the effectiveness of electroacupuncture in patients with syndrome of miofacial pain associated with temporomandibular joint dysfunction. Methods: A quasi-experiment study of therapeutic intervention in 80 patients assisted in Dr. Juan Bruno Zayas Alfonso Teaching General Hospital from Santiago de Cuba, was carried out from November, 2018 to the same month in 2021, who suffered from miofacial pain due to dysfunction in the temporomandibular joint. These were assigned in an alternating way in two therapeutic groups of 40 members each one: that of study, to which electroacupuncture was applied, and that of control, which received conventional pharmacological medication; then, they were clinically evaluated at the third, fifth, seventh and tenth days after the therapy. The variables were statistically processed applying the percentage as summary measure and the chi-square test to estimate differences as for the average time of good evolution, with a level of significance of 0.05. Results: Before beginning the therapy, the pain was intense in most of the patients of both groups; however, at the third day of the therapies, the evolution had been good in 45.0 % of the study group and 32.5 % of the control group, and the fifth day this percentage had increased at 60.0 in those that received electroacupuncture, but stayed equally in those that were treated conventionally. When concluding the intervention recession or relief of the miofacial pain in 97.5 % of the cases and in 90.0 % of the controls was achieved. Conclusions: The electroacupuncture was clinically more effective than the conventional medication to palliate the miofacial pain caused by the temporomandibular disorders, with a less average time of good therapeutic response.

Al finalizar la intervención se había logrado la recesión o el alivio del dolor miofacial en 97,5 % de los casos y en 90,0 % de los controles. Conclusiones: La electroacupuntura resultó clínicamente más efectiva para paliar el dolor miofacial producido por los trastornos temporomandibulares, con un menor tiempo promedio de buena respuesta terapéutica.

RESUMO Antecedentes: A acupuntura é um tratamento para a dor neuropática, mas seu mecanismo permanece obscuro. Estudos anteriores mostraram que a analgesia foi induzida em ratos com dor neuropática quando o conteúdo de adenosina da medula espinhal aumentou após a eletroacupuntura (EA); no entanto, o mecanismo por trás desse aumento induzido por eletroacupuntura não foi esclarecido. Objetivo: Este estudo teve como objetivo determinar o papel que a ecto-5'-nucleotidase desempenha na analgesia induzida por EA para dor neuropática. Métodos: Realizamos eletroacupuntura no ponto de acupuntura de Zusanli no sétimo dia após estabelecer um modelo de rato de dor neuropática induzida por lesão de constrição crônica. Observamos o limiar de retirada mecânica e o limiar de dor térmica, e detectamos a expressão de ecto-5'-nucleotidase na medula espinhal usando Western blot. Modelos de ratos com lesão de constrição crônica foram injetados intraperitonealmente com α, β-metilenadenosina 5'-difosfato, um inibidor de ecto-5'-nucleotidase, 30 min antes da eletroacupuntura. O conteúdo de adenosina da medula espinhal foi detectado por meio de cromatografia líquida de alta eficiência. Por último, o agonista do receptor de adenosina A1 N6-ciclopentiladenosina foi injetado por via intratecal no edema lombar dos ratos, e a retirada mecânica e os limiares de dor térmica foram reavaliados. Resultados: Analgesia e aumento da expressão de ecto-5'-nucleotidase e conteúdo de adenosina na medula espinhal foram observados 1 h após a eletroacupuntura. α, β-metilenadenosina 5'-difosfato foi capaz de inibir a sobrerregulação do conteúdo de adenosina e analgesia induzida por eletroacupuntura. Após administração de N6-ciclopentiladenosina, a analgesia induzida por eletroacupuntura foi restaurada. Conclusões: Nossos resultados sugerem que a eletroacupuntura em Zusanli pode produzir analgesia em modelos de ratos com lesão de constrição crônica, possivelmente por meio do aumento da expressão de ecto-5'-nucleotidase induzida por eletroacupuntura, levando ao aumento da expressão de adenosina na medula espinhal.

ABSTRACT Background: Acupuncture is a treatment for neuropathic pain, but its mechanism remains unclear. Previous studies showed that analgesia was induced in rats with neuropathic pain when their spinal cord adenosine content increased after electroacupuncture (EA); however, the mechanism behind this electroacupuncture-induced increase has not been clarified. Objective: This study aimed to determine the role that ecto-5’-nucleotidase plays in EA-induced analgesia for neuropathic pain. Methods: We performed electroacupuncture at the Zusanli acupoint on the seventh day after establishing a rat model of neuropathic pain induced through chronic constriction injuries. We observed the mechanical withdrawal threshold and thermal pain threshold and detected the expression of ecto-5’-nucleotidase in the spinal cord using Western blot. Chronic constriction injury rat models were intraperitoneally injected with α,β-methyleneadenosine 5'-diphosphate, an ecto-5’-nucleotidase inhibitor, 30 min before electroacupuncture. The adenosine content of the spinal cord was detected using high-performance liquid chromatography. Lastly, the adenosine A1 receptor agonist N6-cyclopentyladenosine was intrathecally injected into the lumbar swelling of the rats, and the mechanical withdrawal and thermal pain thresholds were reevaluated. Results: Analgesia and increased ecto-5’-nucleotidase expression and adenosine content in the spinal cord were observed 1 h after electroacupuncture. α,β-methyleneadenosine 5'-diphosphate was able to inhibit upregulation of adenosine content and electroacupuncture-induced analgesia. After administration of N6-cyclopentyladenosine, electroacupuncture-induced analgesia was restored. Conclusions: Our results suggest that electroacupuncture at Zusanli can produce analgesia in chronic constriction injury rat models, possibly via the increased ecto-5’-nucleotidase expression induced through electroacupuncture, thus leading to increased adenosine expression in the spinal cord.

Abstract Background: G protein coupled receptor kinase 2 (GRK2) has been demonstrated to play a crucial role in the development of chronic pain. Acupuncture is an alternative therapy widely used for pain management. In this study, we investigated the role of spinal neuronal GRK2 in electroacupuncture (EA) analgesia. Methods: The mice model of inflammatory pain was built by subcutaneous injection of Complete Freund's Adjuvant (CFA) into the plantar surface of the hind paws. The mechanical allodynia of mice was examined by von Frey test. The mice were subjected to EA treatment (BL60 and ST36 acupuncture points) for 1 week. Overexpression and down-regulation of spinal neuronal GRK2 were achieved by intraspinal injection of adeno associated virus (AAV) containing neuron–specific promoters, and microglial activation and neuroinflammation were evaluated by real–time PCR. Results: Intraplantar injection with CFA in mice induced the decrease of GRK2 and microglial activation along with neuroinflammation in spinal cord. EA treatment increased the spinal GRK2, reduced neuroinflammation, and significantly decreased CFA–induced mechanical allodynia. The effects of EA were markedly weakened by non–cell–specific downregulation of spinal GRK2. Further, intraspinal injection of AAV containing neuron–specific promoters specifically downregulated neuronal GRK2, and weakened the regulatory effect of EA on CFA–induced mechanical allodynia and microglial activation. Meanwhile, overexpression of spinal neuronal GRK2 decreased mechanical allodynia. All these indicated that the neuronal GRK2 mediated microglial activation and neuroinflammation, and subsequently contributed to CFA–induced inflammatory pain. Conclusion: The restoration of the spinal GRK2 and subsequent suppression of microglial activation and neuroinflammation might be an important mechanism for EA analgesia. Our findings further suggested that the spinal GRK2, especially neuronal GRK2, might be the potential target for EA analgesia and pain management, and we provided a new experimental basis for the EA treatment of pain.

Abstract Objective: to evaluate diverse scientific evidence on the effectiveness of complementary therapies in the control of lower urinary tract symptoms in the adult and aged male population. Method: a systematic review developed according to the PRISMA checklist. The search was performed in the CINAHL, Embase, LILACS, PEDro, PubMed, Web of Science and Google Scholar databases. Results: a total of 585 records were identified and 12 clinical trials were selected that met the inclusion criteria. The outcomes considered by the studies for analyzing effectiveness of the complementary therapies were validated questionnaires to assess the severity of the lower urinary tract symptoms (sensation of incomplete bladder emptying, frequent urination, intermittent flow, weak flow, pain or difficulty urinating, nocturia and urgency) and urodynamics parameters. The studies analyzed the complementary phytotherapy (n=8) and electroacupuncture (n=4) therapies. Six studies related to phytotherapy showed statistical significance. Electroacupuncture showed a significant improvement in the symptoms in two studies. Conclusion: pytotherapy was effective to control the simptoms related to frequency, urgency, nocturia, incomplete emptying, intermittence, weak flow and effort to initiate urination. To confirm the effectiveness of electroacupuncture, research studies with well-designed methodologies will also be necessary to resolve the divergences between the studies of this review.

Abstract Background: Accumulating evidence has demonstrated that the electroacupuncture (EA) stimulation could effectively alleviate neuropathic pain. The medial prefrontal cortex (mPFC) is a vital part of the cortical representation of pain in the brain, and its glucose metabolism is mostly affected in the progression of pain. However, the central mechanism of EA analgesia remains unclear. Methods: Fifty-four male SD rats were equally randomized into sham surgery (Sham) group, chronic constriction injury (CCI) group and EA stimulation (EA) group. The CCI model, involving ligature of the right sciatic nerve, was established in all animals except the Sham group. EA stimulation was applied on the right side acupoints of Huantiao (GB30) and Yanglingquan (GB34) in the EA group. Paw withdrawal threshold (PWT) and paw thermal withdrawal latency (PWL) were measured. The 18 F-fluorodeoxyglucose positron emission tomography (FDG-PET) was used to evaluate glucose metabolism changes in the mPFC. The expression of glucose transporter 3 (GLUT-3) in the mPFC was determined by immune histochemistry and ELISA. Results: Comparing with CCI groups, EA treatment was obviously reversed CCI-induced mechanical allodynia (P < 0.01), thermal hyperalgesia (P < 0.01) and the increase of glucose metabolism in the left mPFC (P < 0.05). Furthermore, EA treatment significantly decreased the protein expression of GLUT-3 in the left mPFC (P < 0.01). Conclusions: Our results indicate that EA analgesia effect may be related to suppressing the glucose metabolism and GLUT-3 expression in the mPFC. This study could provide a potential insight into the central mechanisms involved in the analgesic effect of EA.

Abstract Pelvic floor disorders are one of the most common complications in male patients with spinal cord injury. The aim of this review was to analyse the available evidence on the efficacy of different treatments used for pelvic floor dysfunctions in men with incomplete spinal cord injuries. The Scopus, Medline, PEDro, Web of Science, Dialnet, Pubmed and Cochrane databases were consulted for papers in Spanish and English published in the last twenty years. Fifteen articles were included, comprising a total of 706 male patients with incomplete spinal cord injury. In male patients with neurogenic bladder and erectile dysfunction, the best results were obtained with neuromodulation and combined treatments (electrotherapy or acupuncture / electroacupuncture with catheterization or bladder training).

Se consultaron las bases de datos Scopus, Medline, PEDro, Web of Science, Dialnet, Pubmed y Cochrane, en castellano e inglés en los últimos veinte años. Se incluyeron quince artículos con un total de 706 pacientes varones con lesión medular incompleta. La neuromodulación y la combinación de tratamientos (electroterapia o acupuntura / electroacupuntura con cateterismo o entrenamiento de vejiga) reportan los mejores resultados en vejigas neurógenas y disfunciones eréctiles.

RESUMO Introdução: A acupuntura tem sido amplamente utilizada para alívio de dor. No entanto, seus mecanismos são muito pouco conhecidos. Objetivo: Investigar a relação entre o efeito analgésico da eletroacupuntura e a regulação da expressão de adenosina e de substância P. Métodos: Utilizou-se um modelo de dor inflamatória crônica em ratos por injeção única do Adjuvante Completo de Freund e, em seguida, os animais foram tratados com eletroacupuntura diariamente. Foram aplicadas sete sessões bilaterais de eletroacupuntura (ST36 e BL60, 0,5 a 1,5 mA, força inicial de 0,5 mA, aumentada em 0,5 mA a cada 10 minutos, 30 minutos por sessão, uma sessão por dia) em ratos com Adjuvante Completo de Freund, por sete dias. O efeito analgésico da eletroacupuntura foi avaliado pela medida do limiar de retirada da pata em ratos que receberam estimulações mecânica e térmica. Resultados: A estimulação diária com eletroacupuntura aumentou efetivamente o limiar de retirada da pata em ratos com Adjuvante Completo de Freund. A eletroacupuntura aumentou o nível de adenosina na região zusanli. Estudos posteriores mostraram que a eletroacupuntura poderia diminuir os níveis de substância P, receptor de neurocinina-1, fator de necrose tumoral-alpha, interleucina-1β, interleucina-6 e CD68 nos gânglios da raiz dorsal. Curiosamente, a injeção direta de antagonistas do receptor de adenosina A1 ou de substância P, ou a transecção da raiz do nervo dorsal, podem prejudicar significativamente as ações analgésicas induzidas pela eletroacupuntura em ratos com Adjuvante Completo de Freund e reduzir os níveis de substância P, receptor de neurocinina-1, fator de necrose tumoral-alfa, interleucina-1β, interleucina-6 e CD68. Por fim, confirmamos que a injeção direta de um agonista do receptor da adenosina A1 reproduziu os efeitos analgésicos da eletroacupuntura. Conclusão: Nossos resultados indicam a regulação da secreção da substância P mediada pela adenosina. A via mediada pela substância P pode estar envolvida no processo de analgesia por eletroacupuntura em ratos.

ABSTRACT Background: Acupuncture has been widely used for alleviating pain. However, its mechanisms remain largely enigmatic. Objective: In the present study, we focused on whether the analgesic effect of electroacupuncture is related to its regulation on adenosine and substance P expression. Methods: We established chronic inflammatory pain model in rats through a single injection of Complete Freund’s Adjuvant, and then we treated animals using daily electroacupuncture. We applied seven bilateral sessions of electroacupuncture (ST36 and BL60, 0.5 to 1.5 mA, initial strength of 0.5 mA, increased by 0.5 mA every 10 minutes, for 30 minutes per session, one section per day) to Complete Freund’s Adjuvant rats for seven days. The analgesic effect of electroacupuncture was evaluated by measuring paw withdrawal threshold in rats that received mechanical and thermal stimulation. Results: Daily electroacupuncture stimulation effectively increased paw withdrawal threshold in Complete Freund’s Adjuvant rats. Electroacupuncture increased the adenosine level in zusanli. A further study showed that electroacupuncture could decrease substance P, neurokinin-1 receptor, tumor necrosis factor-alpha, interleukin-1β, interleukin-6 and CD68 levels in dorsal root ganglion. Interestingly, direct injection of adenosine A1 or substance P receptor antagonists, or dorsal nerve root transection could significantly impair electroacupuncture induced analgesic actions in Complete Freund’s Adjuvant rats could and reduce the levels of substance P, neurokinin-1 receptor, tumor necrosis factor-alpha, interleukin-1β, interleukin-6 and CD68. Finally, we confirmed that direct injection of adenosine A1 receptor agonist replicated the analgesic effect of electroacupuncture. Conclusion: Our results indicate regulation of adenosine-mediated substance P secretion. Substance P-mediated pathway may be involved in the analgesia process by electroacupuncture in rats.

Abstract Background: Acupuncture, a therapy of traditional Chinese medicine, is confirmed to exert the therapeutic action on polycystic ovary syndrome (PCOS). However, the detailed therapeutic mechanisms of acupuncture in PCOS remain ambiguous. In this study, we further investigated whether electroacupuncture (EA) alleviated PCOS-like symptoms in rats via regulating a metabolic regulator, sterol regulatory element binding protein-1 (SREBP1). Methods: The PCOS-like rat model was built by hypodermic injection with dehydroepiandrosterone (DHEA). The rats were subjected to EA intervention (ST29 and SP6 acupuncture points) for 5 weeks. Primary granulosa cells were isolated from control and PCOS-like rats for evaluating insulin resistance, mitochondrial dysfunction and oxidative stress in vitro. Results: The expression of SREBP1 was increased in PCOS-like rats, which was suppressed by EA treatment. In addition, lentivirus-mediated overexpression of SREBP1 restrained EA treatment-induced improvement in pathological changes, serum hormone levels and insulin resistance in rats. In addition, overexpression of SREBP1 repressed insulin-stimulated phosphorylation of insulin receptor β (IR) and AKT in primary granulosa cells. Moreover, upregulation of SREBP1 further exacerbated mitochondrial dysfunction and oxidative stress in granulosa cells isolated from PCOS-like rats. Mechanically, EA treatment suppressed SREBP1 expression through inducing the activation of AMP-activated protein kinase (AMPK) signaling pathway in PCOS-like rats. Conclusion: EA intervention alleviated PCOS-like symptoms in rats via improving IR, mitochondrial dysfunction and oxidative stress through regulating SREBP1, a lipid metabolism regulator. Our findings illuminate the novel protective mechanisms of EA in the treatment of PCOS.
