Objective To refine and optimize the paper-based assessment tool for evaluating neurological function in spinal cord injury patients, and to explore its impact on clinical practice．Methods A comprehensive review of existing literature on neuromotor function assessment in spinal cord injury patients was conducted, complemented by discussions among members of this study．This led to the integration of a preliminary evaluation framework．Subsequently, a two-round Delphi consensus process involving experts was undertaken to finalize the content of the assessment project．Based on this, a paper-based evaluation system was developed and converted into an electronic format by computer professionals．This system was then tested in a clinical setting, where it was administered to 120 spinal cord injury patients at the Spine Surgery Department of Guangzhou First People’s Hospital between 1 August 2021 and 31 May 2023．Patients were randomly assigned to either an experimental group or a control group, allowing for a comparison of accuracy, efficiency, and convenience in clinical application．Results The experimental group demonstrated a notable improvement in assessment accuracy over the control group, with a significant reduction in error rate from 20.3% to 4.7% and a decrease in omission rate from 32.0% to 5.0%．Furthermore, the average assessment time was shortened by 6.0 minutes, markedly enhancing the efficiency of the evaluation process．Conclusions The optimized neurological function assessment system for spinal cord injury patients has proven effective in enhancing both the accuracy and efficiency of assessments, while significantly minimizing subjective errors．This system holds considerable potential for widespread clinical adoption and application．

Objective To explore the effect of Yiqi Huoxue Decoction combined with heat sensitive moxibustion in patients with urinary retention after spinal cord injury (SCI). Methods From July 2019 to July 2021, 80 patients with urinary retention after SCI in our hospital were selected and divided into observation group and control group according to different treatment plans, 40 cases in each group. The control group was given Yiqi Huoxue decoction, and the observation group was treated with heat sensitive moxibustion additionally. Efficacy, urination before and after treatment, bladder function, urodynamic indexes [bladder volume (VH₂O), bladder compliance (BC), pressure of detrusor (Pdet), pressure of vesical (Pves), average flow rate (Qave)] and incidence of adverse events in 2 groups were observed. Results The total effective rate of observation group was 92.50%, higher than that of control group (70.73%, P<0.05). After treatment, bladder function score, average times of urination, average times of urine leakage, average urine volume and residual urine volume in the observation group were lower than those in the control group (P<0.05). After treatment, compared with the control group, the observation group had lower Pves, higher VH₂O, Pdet, Qave and BC (P<0.05). The adverse event rate of the observation group (2.50%) was not significantly different from control group (5.00%, P>0.05). Conclusions Heat sensitive moxibustion combined with Yiqi Huoxue decoction is effective in the treatment of SCI patients with urinary retention, which can improve the symptoms of abnormal urination and promote the recovery of bladder function, and is safe and reliable.

Objective To study the detection rate of cervical disc and spinal cord lesions in patients with cervical spondylosis by magnetic resonance imaging (MRI). Methods A total of 216 patients with cervical spondylosis in our hospital from March 2017 to March 2019 were selected, all of them underwent MRI and computed tomography (CT) examination. The detection rate of cervical spondylosis, imaging signs of cervical spondylosis, and cervical spondylosis of nerve root type and spinal cord type by MRI and CT were compared. Results The detection rates of cervical spondylosis patients with disc herniation and protrusion, disc degeneration, disc annulus fibrosus disease, cervical spinal cord ischemic injury, posterior longitudinal ligament disease, cervical intervertebral space stenosis, uncinate process hyperplasia, vertebral posterior margin osteophyte, facet hyperplasia, bony spinal stenosis, abnormal cervical curvature by MRI examination were higher than that by CT examination (P<0.05). There were no significant differences in the detection rates of foramen stenosis and spinal canal stenosis between MRI and CT examination (P>0.05); the detection rates of intervertebral disc calcification, vertebral facet joint hyperosteogeny and intervertebral disc pneumatosis by MRI examination were lower than that by CT examination; the detections rates of intervertebral disc herniation, ligamentum flavum thickening, spinal degeneration, dural sac compression and nerve root compression by MRI examination were higher than that by CT examination (P<0.05); the detection rates of cervical spondylotic radiculopathy and cervical spondylotic myelopathy by MRI examination were 94.44% and 88.89%, which were higher than 75.00% and 25.25% of the detection rates by CT examination (P<0.05). Conclusion MRI examination of patients with cervical spondylosis can improve the detection rates of intervertebral disc and cervical spinal cord lesions, and has significant signs for a variety of cervical lesions, which is helpful for the differential diagnosis of cervical spondylosis classification, so as to provide scientific basis for the formulation of clinical treatment plan.

Objective To systematically assess the clinical efficacy of surgical treatment versus conservative treatment for CSCIWFD from previously clinical investigations. Methods A systematic search of all the studies published was conducted on the PubMed, Cochrane Library, EMbase, OVID, CNKI, VIP and Wanfang databases. Randomized and non-randomized controlled trials that compared between surgical treatment and conservative treatment for CSCIWFD were identified. Two reviewers independently screened the literature according to the inclusive and exclusive criteria, extracted the data, and assessed the quality of included studies. Meta-analyses were performed to assess variables including Japanese Orthopaedic Association scores(JOA), Neurological function recovery rate, ASIA impairment scale grade, ASIA motor scores. Results ①A total of 13 articles were included, involving 598 patients, of which 371 and 227 patients received sugical or conservative treatment. ②The results of the meta-analysis indicated that, compared with conservative group, surgical group has higher JOA scores[MD=3.08,95%CI(2.71,3.45),Z=16.29,P<0.000 01], better Neurological function recovery rate[MD=15.87,95%CI(9.28,22.46),Z=4.72,P<0.000 01], better ASIA impairment scale grade improvement[OR=2.3,95%CI(1.25,4.15),Z=2.76,P=0.006], and there were no significant differences in the ASIA motor scores[MD=5.45,95%CI(-7.56,18.47),Z=0.82,P=0.41]. Conclusion These result suggests that surgical treatment can improve the neurological function more effectively for patients with cervical spinal cord injury without fracture and dislocation.

Objective To evaluate the effects of intrathecal injection of rapamycin on pain threshold and spinal cord gliacyte activation in rats of neuropathic pain. Methods Healthy 30 male SD rats were randomly divided into 6 groups(n=5 in each group): ① control group without operation or intrathecal injection. ②CCI group without intrathecal injection. ③ intrathecal injection of rapamycin 10 μg(10 μL) 4 hours after CCI operation and the next 2 days once a day. ④ intrathecal injection of NS10 μL 4 hours after CCI operation and the next 2 days once a day. ⑤ intrathecal injection of rapamycin 10 μg(10 μL) 7 days after CCI operation and the next 2 days once a day.⑥ intrathecal injection of NS10 μL 7 days after CCI operation and the next 2 days once a day. Mechanical and thermal threshold were tested 1 day before the CCI operation and 2^th、4^th、6^th、8^th、10^th、12^th、14^th days after the CCI operation for all the rats. Lumbar segment of spinal cords was removed for determination of glial fibrillary acidic protein(GEAP) in spinal cord by immuohistochemistry dyeing and assay in the 14th day after CCI operation for all the rats. Results Mechanical and thermal hyperalgesia emerged on 4th day and maintained till 14th day after CCI operation(P<0.05). After intrathecal injection of rapamycin 4 hours or 7days after CCI, mechanical and thermal threshold significantly increased compared to intrathecal injection of NS(P<0.05). And the sum area of GFAP positive and the mean density of GFAP positive area in the dorsal horn of operation side greatly increased in rapamycin treated groups compared NS treated groups(P<0.05). Conclusion Intrathecal injection of rapamycin may attenuate CCI induced hyperalgesia and inhibit the activation of astrocyte.
