Abstract
RATIONALE Horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV) is a second common canal of Benign Paroxysmal Positional Vertigo (BPPV); its actual incidence may have been underestimated because of its complex pathogenesis. Although the canalith repositioning maneuver is the treatment of choice, it has a high recurrence rate, affecting some patients' lives and psychology. We submit a case report describing acupuncture and wheat grain moxibustion treatment for HSC-BPPV. PATIENT CONCERNS A 70-year-old patient with HSC-BPPV had low acceptability of the otolith repositioning treatment strategy and reported intolerance during the procedure. He turned to acupuncture as a result of recurrent attacks of vertigo. DIAGNOSES Horizontal semicircular canal benign paroxysmal positional vertigo. INTERVENTIONS The intervention project was acupuncture followed by wheat grain moxibustion treatment, administered once every 2 days, 3 times a week. The whole treatment period lasted for 2 months. OUTCOMES The patient's clinical symptoms of vertigo improved significantly after 8 weeks of acupuncture and wheat grain moxibustion treatment. The Dizziness Handicap Inventory (DHI) and Visual Vertigo Analogue Scale (VVAS) scores decreased, thus verifying that the severity of vertigo was reduced. LESSONS This brief clinical report suggests that acupuncture therapy may be a complementary option for treating HSC-BPPV.

Effect of electroacupuncture on haemodynamic changes during intubation for general anaesthesia is mediated by nitric oxide synthase‑3 via the regulation of microRNA‑155, microRNA‑335 and microRNA‑383.

Abstract
Intubation for general anaesthesia is a life‑threatening risk because it can cause haemodynamic changes. Electroacupuncture (EA) has been reported to alleviate the risk of intubation. In the present study, haemodynamic changes were measured at different time points before and after EA. Reverse transcription‑quantitative PCR was performed to measure the expression of micro (mi)RNAs and endothelial NO synthase (eNOS) mRNA. Western blotting was performed to evaluate the expression of eNOS protein. A luciferase assay was used to explore the inhibitory role of miRNAs in eNOS expression. The transfection of miRNA precursors and antagomirs was performed to assess their effect on eNOS expression. The systolic blood pressure, diastolic blood pressure and mean arterial pressure of patients were significantly decreased by EA, while the heart rate of patients was markedly increased. The expression of micro RNA (miR)‑155, miR‑335 and miR‑383 was effectively inhibited by EA in the plasma and peripheral blood monocytes of patients, whereas eNOS expression and NOS production were markedly elevated by EA. The luciferase activity of the eNOS vector was significantly inhibited by miR‑155, miR‑335 and miR‑383 mimics but activated by miR‑155, miR‑335 and miR‑383 antagomirs. miR‑155, miR‑335 and miR‑383 precursors suppressed the expression of eNOS, while miR‑155, miR‑335 and miR‑383 antagomirs enhanced the expression of eNOS. The present study demonstrated that EA may exert a vasodilative effect during intubation for general anaesthesia by promoting NO production and upregulating eNOS expression. The effect of EA on upregulating eNOS expression may be mediated by its inhibitory effect on the expression of miRNA‑155, miRNA‑335 and miRNA‑383.

Abstract
Spinal cord injury (SCI) results from various pathogenic factors that destroy the normal structure and function of the spinal cord, subsequently causing sensory, motor, and autonomic nerve dysfunction. SCI is one of the most common causes of disability and death globally. It leads to severe physical and mental injury to patients and causes a substantial economic burden on families and the society. The pathological changes and underlying mechanisms within SCI involve oxidative stress, apoptosis, inflammation, etc. As a traditional therapy, acupuncture has a positive effect promoting the recovery of SCI. Acupuncture-induced neuroprotection includes several mechanisms such as reducing oxidative stress, inhibiting the inflammatory response and neuronal apoptosis, alleviating glial scar formation, promoting neural stem cell differentiation, and improving microcirculation within the injured area. Therefore, the recent studies exploring the mechanism of acupuncture therapy in SCI will help provide a theoretical basis for applying acupuncture and seeking a better treatment target and acupuncture approach for SCI patients.

The Multi-Modal Risk Analysis and Medical Prevention of Lumbar Degeneration, Fatigue, and Injury Based on FEM/BMD for Elderly Chinese Women Who Act as Stay-Home Grandchildren Sitters. Front Public Health 2021; 9:700148. [PMID: 34888274 PMCID: PMC8648567 DOI: 10.3389/fpubh.2021.700148] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Accepted: 08/09/2021] [Indexed: 11/17/2022] Open
Abstract
Background: An increasing number of Chinese elderly women stay at home and act as grandchildren sitters. In consequence of the frequent load-bearing, chronic lumbar fatigue probably caused a higher risk of lumbar degeneration, fatigue, and injury which has become one of the most important aging and health problems in China. In this study, a multi-mode lumbar finite element model (FEM) with specific bone mineral density (BMD) were developed and validated for further spine injury prevention and control. Methods: The material properties of lumbar vertebra were modified according to degenerated bone mineral density, and geometry was adjusted based on intervertebral disc height. The motion of lifting children was simulated by a 76 year-old Chinese women's FEM, and the stress distribution was calculated and predicted. Results: The pressure of L5-S intervertebral disc in the bending 3-year-old dummy lifting posture was significantly higher than the same posture without lifting, the maximum effective stress of endplate cartilage in the upright child lifting posture was 1.6 times that of the bending without lifting posture. And the fatigue risk limitation frequency of the upright with dummy posture was predicted with the functional equation of fatigue and stress which was deduced by genetic algorithm, which combined with the effective stress of lumbar vertebrae spongy bone calculated from FEM. Conclusions: The child-lifting motion could increase the risk of lumbar degeneration, fatigue, and injury in elderly women, and they should keep below the frequency limit of the motion of lifting children in their daily life. This study could put forward scientific injury prevention guidance to Chinese elderly women who lift children in daily life frequently.

A multi-modal delivery strategy for spinal cord regeneration using a composite hydrogel presenting biophysical and biochemical cues synergistically. Biomaterials 2021; 276:120971.

Abstract
Extensive tissue engineering studies have supported the enhanced spinal cord regeneration by implantable scaffolds loaded with bioactive cues. However, scaffolds with single-cue delivery showed unsatisfactory effects, most likely due to the complex nature of hostile niches in the lesion area. In this regard, strategies of multi-modal delivery of multiple heterogeneous cell-regulatory cues are unmet needs for enhancing spinal cord repair, which requires a thorough understanding of the regenerative niche associated with spinal cord injury. Here, by combining hierarchically aligned fibrin hydrogel (AFG) and functionalized self-assembling peptides (fSAP), a novel multifunctional nanofiber composite hydrogel AFG/fSAP characterized with interpenetrating network is designed. Serving as a source of both biophysical and biochemical cues, AFG/fSAP can facilitate spinal cord regeneration via guiding regenerated tissues, accelerating axonal regrowth and remyelination, and promoting angiogenesis. Giving the synergistic effect of multiple cues, AFG/fSAP implantation contributes to anatomical, electrophysiological, and motor functional restorations in rats with spinal cord hemisection. This study provides a novel multi-modal approach for regeneration in central nervous system, which has potentials for clinical practice of spinal cord injury.

Abstract
The efficacy of electroacupuncture in the treatment of peripheral facial paralysis is known, but the specific mechanism has not been clarified. Glial cell-derived neurotrophic factor (GDNF) has been shown to protect neurons by binding to N-cadherin. Our previous results have shown that electroacupuncture could increase the expression of N-cadherin mRNA in facial neurons and promote facial nerve regeneration. In this study, the potential mechanisms by which electroacupuncture promotes nerve regeneration were elucidated through assessing the effects of electroacupuncture on GDNF and N-cadherin expression in facial motoneurons of rabbits with peripheral facial nerve crush injury. New Zealand rabbits were randomly divided into a normal group (normal control, n = 21), injury group (n = 45) and electroacupuncture group (n = 45). Model rabbits underwent facial nerve crush injury only. Rabbits in the electroacupuncture group received facial nerve injury, and then underwent electroacupuncture at Yifeng (TE17), Jiache (ST6), Sibai (ST2), Dicang (ST4), Yangbai (GB14), Quanliao (SI18), and Hegu (LI4; only acupuncture, no electrical stimulation). The results showed that in behavioral assessments, the total scores of blink reflex, vibrissae movement, and position of apex nasi, were markedly lower in the EA group than those in the injury group. Hematoxylin-eosin staining of the right buccinator muscle of each group showed that the cross-sectional area of buccinator was larger in the electroacupuncture group than in the injury group on days 1, 14 and 21 post-surgery. Toluidine blue staining of the right facial nerve tissue of each group revealed that on day 14 post-surgery, there was less axonal demyelination and fewer inflammatory cells in the electroacupuncture group compared with the injury group. Quantitative real time-polymerase chain reaction showed that compared with the injury group, N-cadherin mRNA levels on days 4, 7, 14 and 21 and GDNF mRNA levels on days 4, 7 and 14 were significantly higher in the electroacupuncture group. Western blot assay displayed that compared with the injury group, the expression of GDNF protein levels on days 7, 14 and 21 were significantly upregulated in the electroacupuncture group. The histology with hematoxylin-eosin staining and Nissl staining of brainstem tissues containing facial neurons in the middle and lower part of the pons exhibited that on day 7 post-surgery, there were significantly fewer apoptotic neurons in the electroacupuncture group than in the injury group. By day 21, there was no significantly difference in the number of neurons between the electroacupuncture and normal groups. Taken together, these results have confirmed that electroacupuncture promotes regeneration of peripheral facial nerve injury in rabbits, inhibits neuronal apoptosis, and reduces peripheral inflammatory response, resulting in the recovery of facial muscle function. This is achieved by up-regulating the expression of GDNF and N-cadherin in central facial neurons.

Abstract
BACKGROUND For spinal-cord-injured (SCI) patients, integrative medicine approaches such as photomedicine and acupuncture can renew hope and offer previously unrecognized ways to help regain function and improve quality of life. OBJECTIVE By understanding the mechanisms of action that these two modalities share, practitioners can better target specific attributes of spinal cord pathophysiology that are limiting recovery. Naturally occurring intervertebral disk disease (IVDD) in dogs affords unparalleled translational opportunities to develop treatment strategies involving photobiomodulation and acupuncture. CONCLUSIONS Insights derived through clinical trials of dogs with IVDD have the potential to raise the standard of care for both human and canine SCI patients.

Abstract
Background: We previously showed that electroacupuncture (EA) at Jiaji points promotes expression of adhesion molecule L1 in spinal cord tissue after mouse spinal cord injury (SCI) and contributes to recovery of neural functions. Objective: We investigated the effects of EA on downstream signaling molecules of L1 and molecules relevant to apoptosis with the aim to understand the underlying molecular mechanisms. Methods: Female C57BL/6 mice were divided into a sham group, injury group, injury+acupuncture (AP) group and injury+EA group. We investigated the changes in cognate L1-triggered signaling molecules after SCI by immunofluorescence staining and immunoblot analysis. Results: Protein levels of phosphatase and tensin homolog (PTEN) and p53 were decreased by EA at different time points after injury, whereas the levels of phosphorylated mammalian target of rapamycin (pmTOR), p-Akt and phosphorylated extracellular signal-regulatedkinase (p-Erk) were increased. Also, levels of myelin basic protein (MBP) were increased by EA. AP alone showed less pronounced changes in expression of the investigated molecules, when compared to EA. Conclusion: We propose that EA contributes to neuroprotection by inhibiting PTEN and p53 expression and by increasing the levels of pmTOR/Akt/Erk and of MBP after SCI. These observations allow novel insights into the beneficial effects of EA via L1-triggered signaling molecules after injury.

Abstract
Spinal cord injury is a devastating neurological disease in desperate need of a cure. We have previously shown that overexpression of the adhesion molecule L1 contributes to locomotor recovery after injury and were therefore interested in how electro-acupuncture would influence the expression of this molecule. Here, we investigated the effects of electro-acupuncture at "Jiaji" points (EX-B2), newly established by us, in young adult mice to determine whether improved recovery via electro-acupuncture could be due to enhanced L1 expression. Locomotor function, as evaluated by the Basso Mouse Scale score and by catwalk gait parameters, was improved by electro-acupuncture at different time points after injury in parallel with enhanced levels of L1 expression. Interestingly, the levels of the astrocytic marker glial fibrillary acidic protein (GFAP) were also increased, but only in the early phase after injury, being reduced at later stages during recovery. Acupuncture alone showed less pronounced changes in expression of these molecules. We propose that electro-acupuncture improves regeneration in part by promoting the L1 expression and beneficial activation of stem cells, and by differentially modulating the expression of GFAP by promoting regeneration-conductive astrocytic responses at initial stages and reducing regeneration-adversive activation in the secondary stages. Expression of the stem cell marker nestin was upregulated by electro-acupuncture in the acute stage. The combined observations show for the first time in mice the beneficial functions of electro-acupuncture at Jiaji points in the spinal cord injury mouse model and provide novel insights into some molecular mechanisms underlying electro-acupuncture in spinal cord injury.

Abstract
Electroacupuncture at Dazhui (GV14) and Mingmen (GV4) on the Governor Vessel has been shown to exhibit curative effects on spinal cord injury; however, the underlying mechanism remains poorly understood. In this study, we established rat models of spinal cord injury using a modified Allen's weight-drop method. Ninety-nine male Sprague-Dawley rats were randomly divided into three equal groups: sham (only laminectomy), SCI (induction of spinal cord injury at T10), and EA (induction of spinal cord injury at T10 and electroacupuncture intervention at GV14 and GV4 for 20 minutes once a day). Rats in the SCI and EA groups were further randomly divided into the following subgroups: 1-day (n = 11), 7-day (n = 11), and 14-day (n = 11). At 1, 7, and 14 days after electroacupuncture treatment, the Basso, Beattie and Bresnahan locomotor rating scale showed obvious improvement in rat hind limb locomotor function, hematoxylin-eosin staining showed that the histological change of injured spinal cord tissue was obviously alleviated, and immunohistochemistry and western blot analysis showed that Wnt1, Wnt3a, β-catenin immunoreactivity and protein expression in the injured spinal cord tissue were greatly increased compared with the sham and SCI groups. These findings suggest that electroacupuncture at GV14 and GV4 upregulates Wnt1, Wnt3a, and β-catenin expression in the Wnt/β-catenin signaling pathway, exhibiting neuroprotective effects against spinal cord injury.
