Mechanism of Shikonin on spinal cord injury in rats based on TNFR/RIPK1 pathway / 中国骨伤

OBJECTIVE@#To explore the effect of shikonin on the recovery of nerve function after acute spinal cord injury(SCI) in rats.@*METHODS@#96 male Sprague-Dawley(SD)rats were divided into 4 groups randomly:sham operation group (Group A), sham operation+shikonin group (Group B), SCI+ DMSO(Group C), SCI+shikonin group (Group D).The acute SCI model of rats was made by clamp method in groups C and D . After subdural catheterization, no drug was given in group A. rats in groups B and D were injected with 100 mg·kg-1 of shikonin through catheter 30 min after modeling, and rats in group C were given with the same amount of DMSO, once a day until the time point of collection tissue. Basso-Beattie-Bresnahan(BBB) scores were performed on 8 rats in each group at 6, 12, and 3 d after moneling, and oblique plate tests were performed on 1, 3, 7 and 14 d after modeling, and then spinal cord tissues were collected. Eight rats were intraperitoneally injected with propidine iodide(PI) 1 h before sacrificed to detection PI positive cells at 24 h in each group. Eight rats were sacrificed in each group at 24 h after modeling, the spinal cord injury was observed by HE staining.The Nissl staining was used to observe survivor number of nerve cells. Western-blot technique was used to detect the expression levels of Bcl-2 protein and apoptosis related protein RIPK1.@*RESULTS@#After modeling, BBB scores were normal in group A and B, but in group C and D were significantly higher than those in group A and B. And the scores in group D were higher than those in group C in each time point (P<0.05). At 12 h after modeling, the PI red stained cells in group D were significantly reduced compared with that in group C, and the disintegration of neurons was alleviated(P<0.05). HE and Nissl staining showed nerve cells with normal morphology in group A and B at 24h after operation. The degree of SCI and the number of neuronal survival in group D were better than those in group C, the difference was statistically significant at 24h (P<0.05). The expression of Bcl-2 and RIPK1 proteins was very low in group A and B;The expression of RIPK1 was significantly increased in Group C and decreased in Group D, with a statistically significant difference (P<0.05);The expression of Bcl-2 protein in group D was significantly higher than that in group C (P<0.05).@*CONCLUSION@#Shikonin can alleviate the pathological changes after acute SCI in rats, improve the behavioral score, and promote the recovery of spinal nerve function. The specific mechanism may be related to the inhibition of TNFR/RIPK1 signaling pathway mediated necrotic apoptosis.

ObjectiveTo observe the clinical efficacy of modified Shenqi Pill （肾气丸） plus Tongdu Tiaoshen Acupuncture （通督调神针刺） in the treatment of neurogenic bladder after spinal cord injury of kidney-yang deficiency syndrome. MethodsForty-six patients were randomly divided into 23 cases each in the control group and the treatment group. Both groups were given conventional treatment， i.e. oral methylcobalamin tablets （0.5 mg each time， 3 times a day） and paraplegic conventional acupuncture （once a day， 6 consecutive days a week）. The control group was given simple bladder function rehabilitation training on the basis of the conventional treatment； and the treatment group was given modified Shenqi Pill orally （1 dose a day， 150 ml each time， taken warmly in morning and evening） and Tongdu Tiaoshen Acupuncture （once a day， 6 consecutive days per week） in addition to what were given to the control group. The treatment course lasted for 4 weeks. The 24 h urination frequency， 24 h urine leakage frequency， 24 h single urine volume， bladder residual urine volume， international lower urinary tract symptom （LUTS） score， traditional Chinese medicine （TCM） syndrome score were compared between the two groups， and clinical effectiveness and TCM syndrome effectiveness were compared between the two groups after treatment. ResultsTwenty patients in each group were finally analyzed in this study. The number of 24 h urination， the number of 24 h urine leakage， bladder residual urine volume， LUTS score， and the TCM syndrome scores decreased after treatment in both groups， and the 24 h single urine volume increased （P＜0.01）； and much more improvement was found of each index in the treatment group than in the control group （P＜0.05 or P＜0.01）. The total clinical effectiveness and TCM syndrome effectiveness in the treatment group was 85.00% （17/20） respectively， which were statistically significantly higher than 45.00% （the total clinical effectiveness， 9/20） and 60.00% （TCM syndrome effectiveness， 12/20） in the control group （P＜0.01）. ConclusionModified Shenqi Pill plus Tongdu Tiaoshen Acupuncture can signi-ficantly improve the clinical symptoms of neurogenic bladder patients after spinal cord injury of kidney-yang deficiency syndrome， having better effectiveness than simple bladder function rehabilitation training， and its mechanism may be related to the improvement of the injured nerve function innervating the bladder.

Effect of high-frequency repetitive transcranial magnetic stimulation in M1 region combined with dorsolateral prefrontal cortex on electroencephalogram θ frequency band amplitude of patients with neuropathic pain after spinal cord injury / 中国康复理论与实践

ObjectiveTo explore the efficacy of high-frequency repetitive transcranial magnetic stimulation (rTMS) in M1 region combined with dorsolateral prefrontal cortex (DLPFC) on electroencephalogram (EEG) θ frequency band amplitude of patients with neuropathic pain (NP) after spinal cord injury. MethodsFrom June, 2022 to June, 2023, 50 NP patients after SCI in Qingdao University Affiliated Hospital were included and divided into M1 region stimulation group (n = 25) and M1 region combined with DLPFC stimulation group (the combined stimulation group, n = 25). M1 region stimulation group received 10 Hz rTMS in the left M1 region, while the combined stimulation group received same stimulation in left M1 region combined with DLPFC, for three weeks. Before and after intervention, the pain was assessed with Short Form of McGill Pain Questionnaire (SF-MPQ), the depression and anxiety status were evaluated using Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA), and the EEG θ frequency band amplitude was recorded to detect the changes of brain electrophysiological activity. ResultsFour cases in M1 region stimulation group, and two cases in the combined stimulation group were dropped. After intervention, the total score of SF-MPQ and the scores of the subscales, the scores of HMMD and HAMA decreased in both groups (|t| > 2.523, P < 0.05). The EEG θ frequency band amplitude significantly reduced in the prefrontal and frontal regions in M1 region stimulation group (|t| > 5.243, P < 0.001), and it also significantly reduced in the prefrontal, frontal regions, central and parietal regions in the combined stimulation group (|t| > 4.630, P < 0.001). All the scores were lower (|t| > 2.270, Z = -1.973, P < 0.05), and the EEG θ frequency band amplitude in the prefrontal, frontal regions, central and parietal regions were lower (P < 0.05) in the combined stimulation group than in M1 region stimulation group. ConclusionHigh frequency rTMS is an effective analgesic method on NP after SCI, which can improve their depression and anxiety symptoms and reduce the EEG θ frequency band amplitude. Compared with M1 region rTMS stimulation, the combination of M1 region and DLPFC rTMS is more effective.

Obstacles and Facilitators in Daily Living Activities Among Persons with Spinal Cord Injury: A Systemic Review

@#Introduction: This systematic review aimed to investigate the level of participation, obstacles, and facilitator factors that influence activities of daily living among persons with spinal cord injury (SCI). Methods: A comprehensive search was conducted in four online databases, namely Google Scholar, PubMed, OT Seeker, and Cochrane Library covering the ten-years period from January 2012 to December 2022. Inclusion criteria encompassed original published studies in English focusing on daily activities, work, participation, obstacles, and facilitators in persons with SCI. Non-peer review sources (e.g., abstracts, grey literature, preprints), and studies unrelated to occupational therapy were excluded. The selected studies were assessed for quality using McMaster University Occupational Therapy Evidence-Based Practice critical review form. Results: Out of the 678 articles identified, ten studies were included after the screening, exploring participation in daily living activities, employment, return to work, leisure activities, family tasks, and community mobility among persons with SCI. Obstacles and facilitators influencing participation in activities of daily living were classified using the International Classification of Functioning, Disability, and Health (ICF) framework. This review highlighted that long-term participation is challenging for persons with SCI, affected by obstacles such as body functions, pain, low self-esteem, and environmental and social factors. Conclusion: The findings underscore the importance of adopting a multidisciplinary rehabilitation approach to enhance participation in daily activities for persons with SCI. Occupational therapy plays a significant role in improving participation levels among persons with SCI.

Effect of 12-week sports intervention programme on physical fitness and sports performance in individuals with spinal cord injury

Objectives: Inactivity in individuals with spinal cord injury (SCI) results in low physical fitness, cardiopulmonary endurance and poor quality of life. Sports participation is known to enhance physical fitness. Therefore, the present study evaluated effect of a structured, 12-week MGM Sports Intervention for Sports Intervention Program for SCI (SPISI) on physical fitness and throw-ball performance in individuals with SCI. Materials and Methods: The study was conducted at MGM School of Physiotherapy and Spinal Cord Injury Rehabilitation centre in Navi Mumbai, India. Following ethical approval, 15 individuals with SCI (80% males and 20% females mean age 33.1 ± 7.2 years) were recruited. Upper-extremity explosive power (medicine-ball-throw), agility (t-test), cardiorespiratory endurance (incremental shuttle wheelchair propulsion test) and ball-throwing capacity (maximal-pass test) were evaluated pre- and post-12-week sports intervention programme (SPISI). The protocol involved strength training of upper extremity training at 50% 1 repetition maximum and participation in throw-ball sport. Results: Following training, increase in upper extremity explosive power (11%), cardiopulmonary endurance (5%), agility (8%) and ball-throwing capacity in distance (7%) (P < 0.05) was observed. The large effect size was observed for sports performance (maximal-pass test distance-Cohen’s d 1.261), moderate for cardiorespiratory endurance (incremental wheelchair propulsion test distance Cohen’s d 0.517) and upper extremity explosive power (medicine-ball throw distance 0.593). Increment in all outcome variables was greater than minimal clinically important difference. Conclusion: Sports intervention programme (SPISI) for 12 weeks brought about minimal clinically important difference in upper-extremity explosive power, agility, cardiorespiratory endurance and sport-specific performance and should be included as an integral component of rehabilitation of individuals with SCI.

Neuroprotective effect and mechanism of cPLA2 inhibitor increases autophagic flux on spinal cord injury / 中国骨伤

OBJECTIVE@#To investigate the mechanism of cytosolic phospholipase A2(cPLA2) inhibitor to improve neurological function after spinal cord injury (SCI).@*METHODS@#Thirty-six 3 months old female SD rats, with body mass (280±20) g, were divided into three groups (n=12):sham group, SCI group, and SCI+ arachidonyl trifluoromethyl ketone(AACOCF3) group. Balloon compression SCI model was established in all three groups. In the sham model group, the spinal cord compression model was created after the balloon was placed without pressure treatment, and the remaining two groups were pressurized with the balloon for 48 h. After successful modeling, rats in the SCI+AACOCF3 group were injected intraperitoneally with AACOCF3, a specific inhibitor of cPLA2. The remaining two groups of rats were injected intraperitoneally with saline. The animals were sacrificed in batches on 7 and 14 days after modeling, respectively. And the damaged spinal cord tissues were sampled for pathomorphological observation, to detect the expression of cPLA2 and various autophagic fluxPrelated molecules and test the recovery of motor function.@*RESULTS@#Spinal cord histomorphometry examination showed that the spinal cord tissue in the sham group was structurally intact, with normal numbers and morphology of neurons and glial cells. In the SCI group, spinal cord tissue fractures with large and prominent spinal cord cavities were seen. In the SCI+AACOCF3 group, the spinal cord tissue was more intact than in the SCI group, with more fused spinal cord cavities, more surviving neurons, and less glial cell hyperplasia. Western blot showed that the sham group had the lowest protein expression of LC3-Ⅱ, Beclin 1, p62, and cPLA2 compared with the SCI and SCI+AACOCF3 groups (P<0.05) and the highest protein expression of LC3-Ⅰ (P<0.05). P62 and cPLA2 expression in the SCI group were higher than in the SCI+AACOCF3 group (P<0.05). Behavioral observations showed that the time corresponding to BBB exercise scores was significantly lower in both the SCI and SCI+AACOCF3 groups than in the sham group (P<0.05). Scores at 3, 7, and 14 days after pressurization were higher in the SCI+AACOCF3 group than in the SCI group (P<0.05).@*CONCLUSION@#cPLA2 inhibitors can reduce neuronal damage secondary to SCI, promote neurological recovery and improve motor function by improving lysosomal membrane permeability and regulating autophagic flux.

Effect of Shionone on Neuron Apoptosis After Spinal Cord Injury in Mice / 中国医学科学院学报

Objective To explore the effect of shionone(SHI)on motor function in the mouse model of spinal cord injury(SCI)and probe into the underlying molecular mechanism.Methods C57BL/6 mice were treated to induce the SCI model and then assigned into a model group(SCI group),a SCI+SHI group,and a sham surgery(control)group.The Basso mouse scale(BMS)score was determined to evaluate the recovery of motor function in SCI mice.Hematoxylin-eosin(HE)staining,Nissl staining,and immunofluorescence staining were employed to examine the fibrosis,morphological changes of neurons,and neuron apoptosis in the spinal cord tissue of SCI mice,respectively.The mouse hippocampal neuronal cell line HT22 was cultured in vitro and then classified into tumor necrosis factor α(TNF-α)induction and SHI groups.Western blotting was employed to determine the expression of apoptosis-associated proteins.Network pharmacology,gene ontology annotation,and Kyoto Encyclopedia of Genes and Genomes pathway enrichment were employed to predict the possible molecular targets and signaling pathways of SHI in promoting functional recovery from SCI.Furthermore,the prediction results were verified by in vitro and in vivo experiments.Results Compared with the SCI group,the SCI+SHI group showed increased BMS score on days 21,28,35,and 42(P=0.003,P=0.004,P=0.023,and P=0.007,respectively),reduced area of spinal cord fibrosis(P=0.021),increased neurons survived(P=0.001),and down-regulated expression of cleaved cysteine aspastic acid-specific protease 3(cleaved Caspase-3)(P=0.017).Compared with the TNF-α group,the SHI group presented down-regulated expression levels of cleaved Caspase-3 and Bax(P=0.010,P=0.001)and up-regulated expression level of Bcl-2(P=0.001).The results of bioinformatics analysis showed that SHI might improve the motor function of SCI mice via the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)signaling pathway.The results of in vivo and in vitro experiments showed that SHI inhibited the phosphorylation of PI3K and Akt in SCI mice or HT22 cells exposed to TNF-α(all P<0.05).The number of apoptotic HT22 cells after treatment with insulin-like growth factor 1 was higher than that in the SHI group(P=0.003).Conclusion SHI may inhibit neuron apoptosis via the PI3K/Akt signaling pathway,thereby promoting the recovery of motor function in SCI mice.

OBJECTIVES@#To observe the clinical efficacy of timing umbilical therapy for neurogenic bladder after spinal cord injury based on the midnight-noon and ebb-flow doctrine.@*METHODS@#Sixty patients with neurogenic bladder after spinal cord injury were randomly divided into a trial group and a control group, with 30 patients in each group. In the trial group, based on the midnight-noon and ebb-flow doctrine, umbilical therapy was given at the time zone, 15:00 to 17:00. In the control group, umbilical therapy was delivered at any time zones except the period 15:00 to 17:00. The herbal plaster was remained on the umbilicus for 4 h each time, once daily. One course of treatment was composed of 2 weeks and the treatment lasted 4 weeks. Before and after treatment, the urodynamic indexes (maximum urinary flow rate [Qmax], maximum detrusor pressure [Pdet-max], residual urine volume [RUV]), voiding diary (average daily number of voiding, average daily number of leakage, average daily voided volume), neurogenic bladder symptom score (NBSS), the score of urinary symptom distress scale (USDS) and the score of World Health Organization quality of life assessment-BREF (WHOQOL-BREF) were compared between the two groups; and the clinical efficacy of the two groups was assessed.@*RESULTS@#After treatment, Qmax, Pdet-max, the average daily voided volume and the scores of WHOQOL-BREF were increased (P<0.05); and RUV, the average daily number of voiding, the average daily number of leakage, NBSS and the scores of USDS were all reduced (P<0.05) in comparison with those before treatment in the two groups. When compared with those in the control group, Qmax, Pdet-max, the average daily voided volume and the score of WHOQOL-BREF were all higher (P<0.05); and RUV, the average daily number of voiding, the average daily number of leakage, NBSS and the score of USDS were lower (P<0.05) in the trial group. The total effective rate was 96.7% (29/30) in the trial group, higher than that (76.7%, 23/30) in the control group (P<0.05).@*CONCLUSIONS@#Timing umbilical therapy, based on the midnight-noon and ebb-flow doctrine, effectively relieves the symptoms of dysuria and improves the quality of life in patients with neurogenic bladder after spinal cord injury.

Efficacy differences between electroacupuncture and moxibustion for neurogenic bladder after spinal cord injury: a randomized controlled trial / 中国针灸

OBJECTIVE@#To compare the clinical efficacy between electroacupuncture(EA) and moxibustion for neurogenic bladder (NB) after spinal cord injury (SCI).@*METHODS@#One hundred and twenty patients with NB after SCI were randomly divided into an EA group, a moxibustion group, and an intermittent catheterization group, with 40 patients in each group. The patients in the intermittent catheterization group were treated with routine treatment and intermittent catheterization, while the patients in the EA group and the moxibustion group were treated with additional treatments of EA (discontinuous wave, with a frequency of 1.3-1.6 Hz, and intensity based on patient tolerance) and moxibustion, respectively. The acupoints used in both groups were Zhongji (CV 3) and Guanyuan (CV 4), bilateral Zusanli (ST 36), Yinlingquan (SP 9), and Baliao points. Each session lasted for 30 min, once daily, six times a week, for a total of six weeks.The maximum bladder capacity (MBC), residual urine vdume (RUV), detrusor pressure (Pdet) during the filling phase, bladder compliance (BC), maximum renal pelvis separation width of both kidneys, urine white blood cell count, TCM syndrome score, and World Health Organization quality of life assessment-BREF (WHOQOL-BREF) score were compared before and after treatment in the 3 groups. The number of patients in each group who achieved bladder functional balance was recorded, and the clinical efficacy was assessed after treatment.@*RESULTS@#After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were increased (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, urine white blood cell count, and TCM syndrome scores were decreased (P<0.05, P<0.01). In the intermittent catheterization group, MBC, RUV, maximum renal pelvis separation width of both kidneys, and urine white blood cell count were decreased (P<0.05), while BC and WHOQOL-BREF score were increased (P<0.05) after treatment. After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were higher than those in the intermittent catheterization group (P<0.05), while the RUV and TCM syndrome scores were lower than those in the intermittent catheterization group (P<0.05). Moreover, after treatment, the MBC and Pdet in the moxibustion group were higher than those in the EA group (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, and TCM syndrome score in the EA group were lower than those in the moxibustion group (P<0.05). The number of patients who achieved bladder functional balance after treatment in the EA group and the moxibustion group was higher than that in the intermittent catheterization group (P<0.05). The cured and effective rate was 85.0% (34/40) in the EA group and 82.5% (33/40) in the moxibustion group, which were both higher than 65.0% (26/40) in the intermittent catheterization group (P<0.05), there was no significant difference between the EA group and the moxibustion group (P>0.05).@*CONCLUSION@#EA and moxibustion could effectively improve the functional state of bladder in patients with NB after SCI. EA is more effective in reducing residual urine volume and excessive activity of the urethral sphincter, and relieving TCM syndromes, while moxibustion is more effective in increasing the pressure of the detrusor during the filling period and establishing the detrusor reflex.

Verification of the Reliability of the Japanese Version of the Clinical Trunk Control Test / The Japanese Journal of Rehabilitation Medicine

Objective：The Clinical Trunk Control Test (CTCT) is used to assess trunk function worldwide, particularly for patients with spinal cord injury (SCI), with good reliability and validity. In Japan, trunk function evaluation methods specialized for patients with SCI are scarce. The aim of the present study was to create a Japanese version of CTCT (CTCT-J) and verify its reliability.Methods：CTCT-J was created using the double-back translation format. The inter-rater reliability was calculated based on the total CTCT-J score and intraclass correlation coefficient (ICC) for each item. The weighted kappa coefficient was calculated for each subtest. To verify internal consistency, Cronbach's alpha coefficient was calculated for the CTCT-J total score and each item.Results：We enrolled 12 patients with SCI, including ten men and two women, with an average age of 51.9 ± 17.8 years. Nine and three patients had cervical and thoracic SCI, respectively. The ICC for inter-rater reliability ranged from 0.995 to 1.000 (p ＜0.05). The weighted kappa coefficient for each subtest ranged from 0.756 to 1.000 (p ＜0.05). In the internal consistency test, the Cronbach's alpha coefficient for all items was 0.995 (p ＜0.05).Conclusion：We created the CTCT-J with double back translation and verified its reliability. Good inter-rater reliability and internal consistency were observed, indicating its applicability in Japan.

A Case Report of a Patient who Achieved Recovery of Walking Independence with the Adjustment of the Prosthesis after Bilateral Leg Amputation and Spinal Cord Injury / The Japanese Journal of Rehabilitation Medicine

This report describes a case of an amputee with a lumber spinal cord injury who successfully recovered ambulation with the use of prosthesis.A 30-year-old man with schizophrenia underwent amputation of the lower legs and concurrently developed lumbar spinal cord injury from of a suicide attempt. After the treatment of stump plasty and posterior fusion, the patient was transferred to our facility. Lower-extremity prostheses for both legs were fitted, and orthostatic training was commenced following admission. During the initial evaluation, the patient could not maintain a stable standing position because of weakness in the hip extensor muscle. An inflexion angle of the prosthesis was set to 0° to extend the knee joint and achieve standing stability. Appropriate adjustments of the prosthesis were made as required, specifically addressing the paraplegia caused by his lumbar spinal cord injury. Thus, the patient successfully regained ambulation with the treatment.Recovering walking independence after bilateral lower leg amputations or paraplegia caused by lumber spinal cord injury is not uncommon. However, this case is unique in that the muscle weakness caused by lumbar spinal cord injury presented unforeseen difficulties for the patient to achieve ambulation, which is not ordinarily observed in amputation rehabilitation cases. No similar cases have been reported in which patients concurrently suffered from both these conditions in Japan；therefore, this case is extremely rare.

Lower-extremity prostheses for both legs were fitted, and orthostatic training was commenced following admission. During the initial evaluation, the patient could not maintain a stable standing position because of weakness in the hip extensor muscle. An inflexion angle of the prosthesis was set to 0° to extend the knee joint and achieve standing stability. Appropriate adjustments of the prosthesis were made as required, specifically addressing the paraplegia caused by his lumbar spinal cord injury. Thus, the patient successfully regained ambulation with the treatment.Recovering walking independence after bilateral lower leg amputations or paraplegia caused by lumber spinal cord injury is not uncommon. However, this case is unique in that the muscle weakness caused by lumbar spinal cord injury presented unforeseen difficulties for the patient to achieve ambulation, which is not ordinarily observed in amputation rehabilitation cases. No similar cases have been reported in which patients concurrently suffered from both these conditions in Japan；therefore, this case is extremely rare.

Adaptive physical activity and its health benefits for patients with spinal cord injury based on ICF: a scoping review / 中国康复理论与实践

ObjectiveTo analyze adaptive physical activity interventions and their health benefits for patients with spinal cord injury (SCI) based on International Classification of Functioning, Disability and Health (ICF). MethodsA combination of subject headings and free words was employed to search for relevant literature on physical activity in patients with SCI in PubMed, Web of Science, EBSCO and CNKI, from January, 2017 to July, 2022. A scoping review was conducted. ResultsEight English articles were included, from Australia, the United States, Estonia, Canada, Netherlands and Brazil. The study involved 150 patients with SCI and included seven randomized controlled trials and one non-randomized controlled trial. These literatures were primarily from journals in the fields of SCI, neurology, neuromuscular medicine and physical activity, with publication dates concentrated between 2017 and 2021. The included studies involved participants with complete or incomplete SCI, presenting with paraplegia, tetraplegia, and various levels of injury severity (grades A to D). The main functional disorders related to ICF included b710 mobility of joint functions, b715 stability of joint functions, b720 mobility of bone functions, b730 muscle power functions, b735 muscle tone functions, b750 motor reflex functions, b760 control of voluntary movement functions and b770 gait pattern functions; the functions involved in activities and participation included d410 changing basic body position, d415 maintaining a body position, d420 transferring oneself, d445 hand and arm use, d450 walking, d455 moving around, d570 looking after one's health, d610 acquiring a place to live, d910 community life, d920 recreation and leisure; the environmental factors involved were e1151 assistive products and technology for personal use in daily living, and e1401 assistive products and technology for culture, recreation and sport. Physical activity intervention sites mainly included home, community, medical or rehabilitation institutions. The physical activity could be classified into prevention, health promotion, treatment and rehabilitation. Patients with SCI had completed acute and subacute rehabilitation in medical and rehabilitation institutions, and returned to their families and communities, and some of them received services in medical and rehabilitation institutions from time to time. The forms of physical activity included strength training combined with routine nursing, short-term resistance training, hydrotherapy and robot treadmill activities, functional electrical stimulation and therapeutic exercise, progressive exercise training based on exoskeleton of power machine, leg bicycle assisted by electrical stimulation combined with manual bicycle, and acute exercise with different intensity. The activity frequency was twelve to 60 minutes a time, two to three times a week, lasting for three to 16 weeks, and the activity intensity was mainly medium to high. The health benefits of physical activity on patients with SCI were mainly reflected in four aspects: physical and mental health, activity and behavior health, environmental factors, quality of life and well-being. In terms of physical and mental health, it helped to improve muscle function (muscle strength, strength perception), walking function (walking speed, walking distance), respiratory and circulatory system functions (peak oxygen uptake, aerobic endurance, cardiopulmonary function, reducing the risk of cardiopulmonary diseases, etc.), immune system related functions, and improving psychosocial function (fatigue degree). In terms of activity and behavioral health, it was helpful to improve activity skills and abilities. In terms of environmental factors, the availability and effectiveness of some auxiliary equipment were confirmed. In terms of quality of life and well-being, it could improve self-living ability and quality of life. ConclusionThis study established a PICO framework for adaptive physical activity and its health effects in patients with SCI based on ICF. Physical activity for patients with SCI can be conducted in various settings, including home, community, or medical and rehabilitation institutions. The physical activities of patients with SCI are characterized by wheelchair-based adaptive physical activities, which are mainly divided into two categories: various aerobic exercises and resistance exercises based on wheelchairs, and physical activities based on auxiliary exercise equipment or intervention methods (such as robot treadmill, power machine exoskeleton, functional electrical stimulation, etc.). The frequency of physical activity in patients with SCI is twelve to 60 minutes a time, two to three times a week, lasting for three to 16 weeks, and the activity intensity is maily medium to high. Therapists and rehabilitation professionals can provide guidance and support through various means, such as online or offline supervision and one-on-one coaching, to promote the health benefits of physical activity for patients with SCI, including improved physical and psychological function, enhanced activity levels, reduced sedentary behavior, and increased self-care abilities and quality of life.

Exercise rehabilitation interventions for people with spinal cord injury and their health benefits: a systematic review of systematic reviews based on ICD-11 and ICF / 中国康复理论与实践

ObjectiveBased on the International Classification of Diseases, Eleventh Revision (ICD-11) and the International Classification of Functioning, Disability and Health (ICF), systematic reviews about the effects of different types of exercise rehabilitation and related interventions on body structure and function, activity and participation, and quality of life in people with spinal cord injury (SCI) were systematically reviewed. MethodsSystematic reviews of exercise rehabilitation and health benefits in patients with spinal cord injury were searched from PubMed, Embase, EBSCO, Web of Science and CNKI, from January, 2015 to January, 2023. ResultsEight English articles were included, from Canada, the United States, South Korea, Australia, Brazil and Netherlands, derived from the fields of physical medicine and rehabilitation, neuromedicine and rehabilitation, and exercise intervention, with the publication date mainly concentrated from 2015 to 2021. A total of 165 randomized controlled trials were involved, with 2 746 participants, aged 18 to 65 years. The diseases were mainly spinal cord injury (complete or incomplete), quadriplegia, paraplegia (thoracic, lumbar and sacral injuries), and motor neuron injury (upper and lower). There were three main types of interventions: passive intervention, using sports assistive devices, such as powered exoskeleton-assisted robots, electric bicycles, etc., and functional electrical stimulation; active interventions, such as stepping exercises; training on flat ground, outdoor walking, and activities of daily living; mixed intervention (active & passive), such as combination of exercise and functional electrical stimulation, combination of exercise and motor assistive devices. The frequency of intervention was ten to 240 minutes a time, two to 18 times a week, with the intensity of low to vigorous, for one to 456 weeks. The intervention sites mainly involved families, community health service centers and sports venues. The health impact mainly involved improving cardiovascular and increasing blood flow velocity in the legs; improving musculoskeletal structure, as well as muscle strength, tolerance and flexibility; relieving spasms and improving reflex excitability of the nervous system; increasing gait speed and walking distance; improving functional independence, such as bowel regularity; improving physical health, such as reducing spasticity and drug use (e.g., baclofen), increasing the immune response to infection, and reducing the risk of disease (vascular dementia and respiratory disease); and improving psychological condition. ConclusionBased on ICD-11 and ICF, this study constructed a research framework for active or passive exercise rehabilitation and related interventions in patients with spinal cord injury. Patients with spinal cord injury can improve their body structure and function, increase their activity and participation, and improve their quality of life and well-being through passive interventions (using motor assistive devices, functional electrical stimulation), active interventions (such as stepping exercises, outdoor walking, etc.), and mixed interventions (combining exercise and functional electrical stimulation, exercise and sports assistive devices).

Mechanism of Buyang Huanwutang Combined with Bone Marrow Mesenchymal Stem Cell Transplantation in Treatment of Spinal Cord Injury Based on PI3K/Akt Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo explore the mechanism of Buyang Huanwutang combined with bone marrow mesenchymal stem cell （BMSC） transplantation in the treatment of spinal cord injury （SCI）. MethodDifferent concentrations （12.5， 25， 50 g·kg-1） of Buyang Huanwutang were administrated to rats by gavage. The spinal cord function of rats was measured by modified Tarlov score， and the most suitable concentration of Buyang Huanwutang was screened out. SD rats were then divided into 6 groups， namely， the sham operation group （gavage of equal amount of normal saline）， the model group （gavage of equal amount of normal saline）， the Buyang Huanwutang group （gavage of 25 g·kg-1 Buyang Huanwutang）， the BMSC transplantation group （tail vein injection of BMSCs 1 mL）， the Buyang Huanwutang+BMSC group （gavage of 25 g·kg-1 Buyang Huanwutang and tail vein injection of BMSCs 1 mL）， the Buyang Huanwutang+BMSC+LY294002 group （gavage of 25 g·kg-1 Buyang Huanwutang and tail vein injection of BMSCs 1 mL and 40 mg·kg-1 LY294002）， with 10 rats in each group. The spinal cord function was measured by the modified Tarlov score， inclined plate test， and latency of cortical somatosensory evoked potential. Immunohistochemistry was used to detect the number of 5-bromo-2-deoxyuracil nucleoside （Brdu）-labeled positive cells in the spinal cord tissue. The protein expression levels of phosphorylated protein kinase B （p-Akt）， glycoprotein 130 （gp130）， and interleukin-6 （IL-6） in spinal cord were detected by Western blot. ResultAs compared with the sham operation group， the Tarlov score and the critical angle of tilt plane in the model group were significantly decreased （P<0.05）， and the latency of cortical somatosensory evoked potential wave and the protein expression levels of p-Akt， gp130， and IL-6 were significantly increased （P<0.05）. As compared with the model group， the Tarlov score and the critical angle of tilt plane in the sham operation group and each treatment group were significantly increased （P<0.05）， and the latency of cortical somatosensory evoked potential wave and the protein expression levels of p-Akt， gp130， and IL-6 were significantly decreased （P<0.05）. As compared with the BMSC group， the Tarlov score and the critical angle of inclined plane in the Buyang Huanwutang+BMSC group increased （P<0.05）， the latency of cortical somatosensory evoked potential wave and the protein expression levels of p-Akt， gp130， and IL-6 decreased （P<0.05）， and the number of Brdu-labeled positive cells increased 5 weeks after transplantation （P<0.05）. As compared with the Buyang Huanwutang+BMSC group， the Tarlov score and the critical angle of the inclined plane in the Buyang Huanwutang+BMSC+LY294002 group increased （P<0.05）， and the latency of cortical somatosensory evoked potential wave and the protein expression levels of p-Akt， gp130， and IL-6 decreased significantly （P<0.05）. Five weeks after transplantation， the number of Brdu-labeled positive cells increased significantly in the Buyang Huanwutang+BMSC+LY294002 group （P<0.05）. ConclusionBuyang Huanwutang can promote BMSCs migration and restore spinal cord function by inhibiting phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signal.

Short-chain fatty acids ameliorate spinal cord injury recovery by regulating the balance of regulatory T cells and effector IL-17+ γδ T cells / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Spinal cord injury (SCI) causes motor, sensory, and autonomic dysfunctions. The gut microbiome has an important role in SCI, while short-chain fatty acids (SCFAs) are one of the main bioactive mediators of microbiota. In the present study, we explored the effects of oral administration of exogenous SCFAs on the recovery of locomotor function and tissue repair in SCI. Allen's method was utilized to establish an SCI model in Sprague-Dawley (SD) rats. The animals received water containing a mixture of 150 mmol/L SCFAs after SCI. After 21 d of treatment, the Basso, Beattie, and Bresnahan (BBB) score increased, the regularity index improved, and the base of support (BOS) value declined. Spinal cord tissue inflammatory infiltration was alleviated, the spinal cord necrosis cavity was reduced, and the numbers of motor neurons and Nissl bodies were elevated. Enzyme-linked immunosorbent assay (ELISA), real-time quantitative polymerase chain reaction (qPCR), and immunohistochemistry assay revealed that the expression of interleukin (IL)‍-10 increased and that of IL-17 decreased in the spinal cord. SCFAs promoted gut homeostasis, induced intestinal T cells to shift toward an anti-inflammatory phenotype, and promoted regulatory T (Treg) cells to secrete IL-10, affecting Treg cells and IL-17+ γδ T cells in the spinal cord. Furthermore, we observed that Treg cells migrated from the gut to the spinal cord region after SCI. The above findings confirm that SCFAs can regulate Treg cells in the gut and affect the balance of Treg and IL-17+ γδ T cells in the spinal cord, which inhibits the inflammatory response and promotes the motor function in SCI rats. Our findings suggest that there is a relationship among gut, spinal cord, and immune cells, and the "gut-spinal cord-immune" axis may be one of the mechanisms regulating neural repair after SCI.
