Objectives This review investigates the effectiveness of electroacupuncture for impairment of motor and sensory functions after spinal cord injury. Methods The databases used for the search were PubMed, Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), National Digital Science Library (NDSL), Koreanstudies Information Service System (KISS), Research Information Sharing Service (RISS), KMBASE, and Oriental Medicine Advanced Searching Integrated System (OASIS). The literature were searched using a total of 9 domestic and foreign databases. Randomized controlled trials (RCTs) using electroacupuncture as an intervention was selected. The selected studies are analyzed the risk of bias through Cochrane risk-of-bias tool, and meta-analysis was perfomed using RevMan version 5.3 (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark). Results A total of 14 RCT studies were selected through 9 domestic and foreign databases, and analyzed. As a result of meta-analysis, when electroacupuncture was performed together with rehabilitation treatment or western drug treatment, it was effective in the recovery of motor and sensory functions of spinal cord injury patients. Conclusions This review suggests that electroacupuncture can be applied as an effective treatment for the recovery of motor and sensory functions of spinal cord injuries. However, there are several limitations, including the small number and heterogeneity of the included studies, as well as their poor methodological quality. Therefore, further, higher-quality studies should be required.

Spinal cord injury (SCI) is a serious nervous system disease that usually leads to the impairment of the motor, sensory, and autonomic nervous functions of the spinal cord, and it places a heavy burden on families and healthcare systems every year. Due to the complex pathophysiological mechanism of SCI and the poor ability of neurons to regenerate, the current treatment scheme has very limited effects on the recovery of spinal cord function. In addition, due to their unique advantages, exosomes can be used as carriers for cargo transport. In recent years, some studies have confirmed that treatment with mesenchymal stem cells (MSCs) can promote the recovery of SCI nerve function. The therapeutic effect of MSCs is mainly related to exosomes secreted by MSCs, and exosomes may have great potential in SCI therapy. In this review, we summarized the repair mechanism of mesenchymal stem cells-derived exosomes (MSCs-Exos) in SCI treatment and discussed the microRNAs related to SCI treatment based on MSCs-Exos and their mechanism of action, which is helpful to further understand the role of exosomes in SCI.

Purpose: This study aimed to compare the effect on nerve regeneration of ultrasound irradiation in rats with peripheral nerve injury. Methods: To investigate alterations of the NCAM immunoreactivity in non-crushed part and crushed part of the spinal cord, the unilateral sciatic nerve of the rats were crushed. The expression of NCAM was used as the marked of peripheral nerve regeneration, and also plays an important role in developing nerve system. Experimental animals were sacrificed by perfusion fixation at post-injury 1, 3, 7, 14 days after ultrasound irradiation. The pulsed US was applied at a frequency of 1MHz and a spatial average-temporal average Intensity of 0.5W/of (20% pulse ratio) for 1 mins. The Luxol fast blue-cresyl violet stain were also done to observe the morphological changes. Results: Alteration of NCAM immunoreactivity in the crushed part and the non-crushed part of lower lumbar spinal cord were observed. NCAM-immunoreactivity cells were some increased in the dorsal horn lamina I, III and cell ventral horn at 1 day after unilateral sciatic nerve injury. However, there was not significant difference in the relationship between crushed part and non-crushed part. NCAM-inmmunoreactivity was remarkably increased at 3 days after unilateral sciatic nerve injuryin the gray matter and white matter. NCAM-immunoreactivity was increased in the ventral horn and post horn of experimental crushed part. Also, NCAM-immunoreactivity in large motor neurons in ventral horns lamina VIII, IX were increased at 7 days after unilateral sciatic nerve injury. At 14 days after sciatic nerve crushed injury, there was no significant difference. All group were decreased for 14 days. In the time course of NCAM expression, all groups showed a significant difference at 3day groups(p<0.05). Whereas, CC group was noted a significant difference between 3day and 7 day group respectively. In NCAM expression, there were significantly increased in all group. In the relationship between CNC group and ENC group, significant difference was detected among 3, 7, 14 day group(p<0.05). The difference between CC group and ENC group were noted in all groups(p<0.05). Conclusion: It is consequently suggested that the effects of the ultrasound irradiation may increase the NCAM immunoreactive neurons and glial cell in the spinal cord after unilateral sciatic nerve crushed injury. Therefore, the increased NCAM immunoreactivity in the spinal cord may reflect the neuronal damage and healing process induced by a ultrasound irradiation after peripheral nerve injury in rat.

Background: The present study was designed to examine the functional recovery following spinal cord injury (SCI) by adjusting the parameters of impact force and dwell-time using the Infinite Horizon (IH) impactor device. Methods: Sprague-Dawley rats (225-240 g) were divided into eight injury groups based on force of injury (Kdyn) and dwell time (seconds), indicated as Force-Dwell time: 150-4, 150-3, 150-2, 150-1, 150-0, 200-0, 90-2 and sham controls, respectively. Results: After T10 SCI, higher injury force produced greater spinal cord displacement (P < 0.05) and showed a significant correlation (r = 0.813) between the displacement and the force (P < 0.05). In neuropathic pain-like behavior, the percent of paw withdrawals scores in the hindpaw for the 150-4, 150-3, 150-2, 150-1 and the 200-0 injury groups were significantly lowered compared with sham controls (P < 0.05). The recovery of locomotion had a significant within-subjects effect of time (P < 0.05) and the 150-0 group had increased recovery compared to other groups (P < 0.05). In addition, the 200-0 and the 90-2 recovered significantly better than all the 150 kdyn impact groups that included a dwell-time (P < 0.05). In recovery of spontaneous bladder function, the 150-4 injury group took significantly longer recovery time whereas the 150-0 and the 90-2 groups had the shortest recovery times. Conclusions: The present study demonstrates SCI parameters optimize development of mechanical allodynia and other pathological outcomes.

The purpose of this study was to evaluate the effect of therapeutic ultrasound after muscle contusion injury by observed immunoreactivity of substance-P that plays an important role in pain transmission. Ultrasound irradiation(1MHz, 1W/$cm^{2}$ continuous mode, treatment time 5 min) was applied through water submersion technique to 1 limb daily by kept off 5cm from muscle belly of gastrocnemius. The result of this study were as follows. 1. The substance-P was expressed in lamina I and II of dorsal horn of spinal cord, also in lamina IV and around of central cannel of spinal cord. Experimental group was lower expressed than control group with the exception of 1 days. 2. The substance-P immunoreactivity was decreased for 5 days together in lumbar and sacral region of all groups, expecially experimental group was rapidly. These data suggest therapeutic ultrasound may stimulate pain relief by diminish of substance-P in dorsal horn of spinal cord.

Spinal cord injury (SCI) has a significant negative effect on the quality of life due to permanent neurologic damage and economic burden by continuous treatment and rehabilitation. However, determining the correct approach to ensure optimal clinical outcomes can be challenging and remains highly controversial. In particular, with the introduction of the concept of early decompression in brain pathology, the discussion of the timing of decompression in SCI has emerged. In addition to that, the concept of "time is spine" has been added recently, and the mortality and complications caused by SCI have been reduced by providing timely and professional treatment to patients. However, there are many difficulties in establishing international clinical guidelines for the timing of early decompression in SCI because policies for each country and medical institution differ according to the circumstances of medical infrastructure and economic conditions in the surgical treatment of SCI. Therefore, we aim to provide a current review of timing of early decompression in patient with SCI.

Objective : To evaluate the magnetic resonance (MR) imaging features that have a statistically significant association with the need for a tracheostomy in patients with cervical spinal cord injury (SCI) during the acute stage of injury. Methods : This study retrospectively reviewed the clinical data of 130 patients with cervical SCI. We analyzed the factors believed to increase the risk of requiring a tracheostomy, including the severity of SCI, the level of injury as determined by radiological assessment, three quantitative MR imaging parameters, and eleven qualitative MR imaging parameters. Results : Significant differences between the non-tracheostomy and tracheostomy groups were determined by the following five factors on multivariate analysis : complete SCI (p=0.007), the radiological level of C5 and above (p=0.038), maximum canal compromise (MCC) (p=0.010), lesion length (p=0.022), and osteophyte formation (p=0.015). For the MCC, the cut-off value was 46%, and the risk of requiring a tracheostomy was three times higher at an interval between 50-60% and ten times higher between 60-70%. For lesion length, the cut-off value was 20 mm, and the risk of requiring a tracheostomy was two times higher at an interval between 20-30 mm and fourteen times higher between 40-50 mm. Conclusion : The American Spinal Injury Association grade A, a radiological injury level of C5 and above, an MCC ${\geq}50%$, a lesion length ${\geq}20mm$, and osteophyte formation at the level of injury were considered to be predictive values for requiring tracheostomy intervention in patients with cervical SCI.
