Electroacupuncture Alleviates Neuropathic Pain through Regulating miR-206-3p Targeting BDNF after CCI.

Background: Electroacupuncture (EA) has benefits for neuropathic pain. However, the underlying mechanisms are still unknown. The current study explores the underlying mechanisms of EA in neuropathic pain of chronic constriction injury (CCI) rats. Material/Methods. Overall, 126 Sprague-Dawley (200-250 g) rats were divided into nine groups randomly: the sham-operated, CCI, CCI+EA, CCI+sham EA, CCI+NS, CCI+AAV-NC, CCI+AAV-miR-206-3p, CCI+EA+NS, and CCI+EA+AAV-miR-206-3p groups. The animals were sacrificed 14 days postsurgery. Mechanical withdrawal threshold (MWT) and thermal withdrawal latency (TWL) tests were used to determine differences in neurobehavioral manifestations. qPCR, western blotting, and immunofluorescence (IF) were carried out to detect the expression levels of miR-206-3p, BDNF, BAX/Bcl-2, TNF-α, and IL-6. Nissl staining was measured to observe morphological changes in neurons. Transmission electron microscopy (TEM) was employed to evaluate microscopic changes in dorsal horn synapses. Results: Hyperalgesia was reduced markedly by EA in the CCI model. The expression level of miR-206-3p was elevated, whereas the expression levels of BDNF, BAX/Bcl-2, TNF-α, and IL-6 were decreased in EA-treated CCI rats. However, a miR-206-3p inhibitor partially abrogated the analgesic effect of EA and resulted in poor behavioral performance and the BDNF, BAX/Bcl-2, TNF-α, and IL-6 expression was elevated as well. Conclusions: EA can relieve neuropathic pain by regulating the miR-206-3p/BDNF pathway, thus exerting anti-inflammatory and antiapoptotic effect.

Nonsurgical spinal decompression system traction combined with electroacupuncture in the treatment of multi-segmental cervical disc herniation: A case report.

RATIONALE: With the spread of computers and mobile phones, cervical spondylosis has become a common occupational disease in clinics, which seriously affects the quality of life of patients. We used a nonsurgical spinal decompression system (SDS) combined with physical therapy electroacupuncture (EA) to treat a case of mixed cervical spondylosis caused by multi-level cervical disc herniation, and we achieved satisfactory results. PATIENT CONCERNS: A 44-year-old Caucasian Asian woman presented with neck pain and numbness on the left side of the limb. MRI showed the patient's C3-C7 segment cervical disc herniation, and the flexion arch of the cervical spine was reversed. DIAGNOSIS: The patient was diagnosed with a mixed cervical spondylosis. INTERVENTIONS: The patient received a month of physical therapy (SDS traction combined with EA). OUTCOMES: Before and after treatment: VAS score of neck pain decreased from 8 to 0; Cervical spine mobility returned to normal; The grip strength of left hand increased from 7.5 kg to 19.2 kg; Cervical curvature index changed from -16.04% to -3.50%; the physiological curvature of the cervical spine was significantly restored. There was no dizziness or neck discomfort at 6 month and 1 year follow-up. LESSONS SUBSETIONS: SDS traction combined with EA is effective for the treatment of cervical disc herniation and can help restore and rebuild the biomechanical balance of the cervical spine.

Acupuncture for patients recovering from lacunar infarction: A protocol for systematic review and meta-analysis.

BACKGROUND: Lacunar infarction (LI) is the mild type in the classification of ischemic stroke, mostly occurs in the middle-aged and elderly, with mild hemiplegia and partial sensory disorder as the main manifestations. In the treatment of LI, acupuncture is often regarded as dominant therapy in the convalescence period. However, acupuncture for treatment of LI in the recovery period lacks high-quality reports and evidence-based medical evidence. Thus, we aim to evaluate the curative effect and safety of acupuncture for LI objectively. METHODS: Pubmed, Cochrane Library, Web of Science, EBSCO, Springer, China National Knowledge Infrastructure, Chinese Scientific and Technical Journals Database (VIP), Wan-fang Database, Chinese Biomedical Literature Database, Chinese Science Citation Database, and other electronic databases will be retrieved from the inception to May, 2021. Randomized controlled trials related to this subject will be searched. The inclusion criteria are established and a detailed literature search strategy is designed through discussion. Article retrieval, screening, excluding repetitive studies, assessment of quality, and data processing will be conducted by 2 reviewers independently using EndNote (X9) and Review Manager (5.3.5). The outcome measures include primary outcome measures (total effective rate, National Institute of Health Stroke Scale score, and Fugl-Meyer Assessment score), secondary outcome measures (blood pressure, plasma glucose, and blood lipid), and safety outcome measures. We will perform a meta-analysis, descriptive analysis, and subgroup analysis based on data conditions. RESULTS: The study of total effective rate, National Institute of Health Stroke Scale score, Fugl-Meyer Assessment score, blood pressure, plasma glucose, blood lipid, and adverse effects will provide evidenced outcome for high-quality synthesis and descriptive analysis. CONCLUSION: This systematic review will kindly provide evidence of whether acupuncture is an effective and safe intervention for LI in the recovery period.

Electro-acupuncture at Governor Vessel improves neurological function in rats with spinal cord injury.

OBJECTIVE: To determine the effects of electro-acupuncture (EA) at Governor Vessel (GV) on the locomotor function in spinal cord injury (SCI) rats and explore the underlying mechanism. METHODS: Thirtytwo male Sprague-Dawley rats were randomly divided into four groups namely: the sham group (with sham operation); the untreated group (without treatment after spinal cord impact); the EA-1 group [EA applied at Baihui (GV 20) and Fengfu (GV 16) after spinal cord impact] and the EA-2 group [with EA applied at Dazhui (GV 14) and Mingmen (GV 4) after spinal cord impact]. Real-time quantitative-polymerase chain reaction (RT-PCR) and Western Blotting were used to assess changes in the mRNA and protein expression levels of brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) at 7 weeks following EA administration. In addition, the Basso-Beattie-Bresnahan (BBB) Locomotor Rating Scale was assessed at 1 day, 1 week, 3 weeks and 7 weeks post-injury. RESULTS: The results showed that EA stimulation induced neuroprotective effects after SCI correlated with the up-regulation of BDNF and NT-3 (P<0.05). Furthermore, EA stimulation at GV 14 and GV 4 could significantly promote the recovery of locomotor function and this may be linked to the up-regulation of BDNF and NT-3 (P<0.05). CONCLUSIONS: EA treatment applied at GV acupoints either within the injury site or adjacent undamaged regions near the brain can improve functional recovery, which may be correlated with the upregulation of BDNF and NT-3. In addition, it would be more effective to administer EA at GV 14 and GV 4 near the injury site of the SCI rats.

Utilization, cost, payment, and patient satisfaction of rehabilitative services in Shandong, China.

OBJECTIVES: China's transformation into a market-based and global economy has had dramatic health policy implications on a system that serves roughly 1.3 billion people. This global perspective is resulting in the integration of Traditional Chinese Medicine (TCM) and western medicine for the treatment of an increasing number of morbidities. However, little research has been conducted that examines patient response to this convergence. This study researches the utilization, cost, payment and patient satisfaction with rehabilitative services received in China. METHODS: A structured questionnaire was administered to 192 patients receiving rehabilitative services in China's Shandong Province. RESULTS: The most frequently ordered TCM therapies were acupuncture (14.1%) and massage therapy (15.6%). The most frequently ordered western therapies were physical therapy (62.5%) and occupational therapy (6.3%). Physical therapy was considered the most cost-effective service at almost half the cost of acupuncture. Almost 85% of respondents had some form of health insurance and 90% expressed satisfaction with their therapy. CONCLUSIONS: Healthcare providers should consider offering TCM and western medicine for morbidities requiring rehabilitative services. In a more global healthcare marketplace, the convergence of these two treatment modalities can lead to higher patient satisfaction and more cost-effective treatments.

Serving billions: a pilot study on clinician-perceived efficacy of rehabilitative services in China.

China has the world's largest number of disabled people, and this number is projected to grow. Although there is ample literature on the utilization and efficacy of Western medicine as it pertains to rehabilitation services, there is far less research on the perceived efficacy of traditional Chinese medicine (TCM). A structured questionnaire was designed for a pilot study on TCM and Western medicine used for rehabilitation services in China, their associated charges, and perceived efficacy. A sample of 33 clinicians responded to the questionnaire. The analysis found that clinicians most frequently prescribed Fenbid and Chinese herbs to treat rehabilitation morbidities, and the most common TCM treatments were acupuncture and massage therapy. The average patient charge for each visit for TCM therapy varied from 56 Yuan (dollars 7.30) for Chinese herbal medicine to 12 Yuan (dollars 1.60) for cupping therapy. The most frequently prescribed Western therapies were occupational, physical, and speech. The average charge for each visit for Western medicine varied from 111 Yuan (dollars 14.60) for physical therapy to 48 Yuan (dollars 6.30) occupational therapy. Clinicians indicated that acupuncture, Chinese herbal medicine, massage, speech, occupational, and physical therapies were "effective" or "highly effective" in treating morbidities requiring rehabilitation services.
