Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Objective:To explore the relationship between stress coping styles and disability levels in patients with spinal cord injury (SCI) .Methods:Totally 300 SCI patients who were hospitalized in the Spinal Surgery Department of three Class Ⅲ Grade A hospitals in Anhui Province from March 2021 to February 2022 were selected by convenience sampling. Data were collected using a general information questionnaire, the Spinal Cord Lesion-related Coping Strategies Questionnaire (SCL-CSQ), and the WHO Disability Assessment Schedule (WHODAS 2.0). Spearman correlation analysis was used to examine the relationship between stress coping styles and disability levels, and multiple linear regression analysis was employed to identify factors influencing disability levels in these patients.Results:A total of 300 questionnaires were distributed, with 269 valid responses received, yielding an effective response rate of 89.67% (269/300). The total score of WHODAS 2.0 for the 269 patients was [91.00 (72.50, 104.00) ], with an item mean score of [2.53 (2.01, 2.89) ], and an average score rate of 59.86%, indicating a moderate to high level of disability. The average score rate for positive stress coping (facing, seeking support, rationalization) was 67.30%, while for negative stress coping (rejection and denial, fantasy, dependency and compromise), it was 64.48%. Negative stress coping was positively correlated with disability levels ( P<0.05), while positive stress coping was negatively correlated with disability levels ( P<0.05). Multiple linear regression analysis showed that occupation, American Spinal Injury Association classification, facing, rejection and denial, and dependency and compromise were factors influencing disability levels in SCI patients ( P<0.05), explaining 50.4% of the total variance in disability levels. Conclusions:The disability level of SCI patients is moderate to high, and stress coping style is an influencing factor. Healthcare professionals should help patients avoid controllable stressors, cultivate effective stress coping strategies, prevent helplessness, to shorten the time window for disability development, and improve patients' quality of life.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Objectives : To investigate the effect of sciatic nerve electrical stimulation ( SNES) on motor function recovery in rats with incomplete spinal cord injury (SCI) and its possible mechanism. Methods : The incomplete SCI model was constructed by modified Allen ′s method. Forty⁃five Sprague⁃Dawley (SD) rats were randomly divided into three groups : Sham , SCI , and SNES. Electrical stimulation parameters were 1 ms pulse width and 100 Hz , with 20 mins each time , once a day for 21 days. The motor function was assessed by Basso⁃Beattie⁃Bresnahan (BBB) locomotor function scale , and the action potential conduction was detected by electrophysiology. Hematoxy⁃lin⁃eosin (HE) staining was used to observe the pathological changes in the spinal cord and the average cross⁃sectional area (CSA) of biceps femoris muscle fibers. The number of brain⁃derived neurotrophic factor (BDNF) and tropomyosin⁃related kinase B (TrkB) positive cells , relative mRNA and protein expression were analyzed by immunohistochemistry , reverse transcription polymerase chain reaction (RT PCR) and Western blot separately. Results: On 21 d , the BBB score and average amplitude of action potential of SNES group were higher than those of SCI group , and the difference was statistically significant (P < 0. 05) . Compared with SCI group , the pathological injury of spinal cord tissue in SNES group was significantly improved , and the average CSA of biceps femoris muscles had a statistical difference (P < 0. 05) . The number of BDNF and TrkB positive cells in SNES group was higher than that in SCI group , and there were statistical differences (P < 0. 05) . The relative mRNA and protein expressions of BDNF and TrkB in SNES group were higher than those in SCI group , with statistical differences ( P <0. 05) . The relative mRNA and protein expressions of BDNF and TrkB in SNES group were higher than those in SCI group , with statistical differences ( P <0. 05) . Conclusion These results show that SNES contributes to alleviating spinal cord tissue injury , promoting the recovery of motor function and delaying the atrophy of muscles below the injury level. The possible mechanism is related to the increased expression of BDNF⁃TrkB proteins.

Objective : To observe the therapeutic effect of electroacupuncture on rabbit knee osteoarthritis (KOA) model and to explore the mechanism of electroacupuncture in the treatment of KOA in rabbits． Methods: Eighteen healthy New Zealand rabbits were randomly divided into a blank control group，a model control group and an electroacupuncture group，with 6 rabbits in each group．The rabbits were kept normally in the blank control group， while the model control and electroacupuncture groups were fixed in a modified Videman left hind limb extension and braking position for 6 weeks to create a KOA model，and electroacupuncture was given to the electroacupuncture group 1 week after completion of the modeling for 4 weeks，five times a week for 20 min each time．The functional score of the left knee joint of rabbits was evaluated by Lequesne's functional algorithm index ; serum and joint fluid interleukin (IL) -1 β and IL-6 levels were measured by enzyme-linked immunosorbent ( ELISA) assay ; serum and joint fluid nitric oxide (NO) levels were measured by Griess ; morphological changes in knee cartilage were observed by hematoxylin-eosin ( HE) staining，and the degree of cartilage degeneration was evaluated by Mankin' s scale ; p-P38MAPK positive cell expression in knee cartilage was observed by immunofluorescence technique. Results : Compared with the blank control group ，the Lequesne score increased in the model control group (P < 0. 05) ; the levels of IL-1 β, IL-6，and NO in serum and joint fluid increased (P＜0. 05) ; the cartilage surface was less smooth and the Mankin score increased (P ＜0. 05) ; and the immunofluorescence staining positive cells increased (P＜0. 05) ．Compared with the model control group，the Lequesne score was reduced in the electroacupuncture group (P ＜0. 05 ) ; the levels of IL-1 β , IL-6 ，and NO in serum and joint fluid were reduced ( P < 0. 05) ; the cartilage surface was smoother，and the Mankin score was reduced (P＜0. 05) ; and the immunofluorescence staining positive cells were reduced (P＜0. 05) ． Conclusion Electroacupuncture can effectively improve knee joint behavior in rabbit KOA model，and the mechanism may be to delay the onset of KOA by decreasing the expression level of inflammatory factors and affecting the expression of MAPK signaling pathway.

Objective To systematically evaluate the adult intraoperatively acquired pressure injury risk prediction model.Methods Related study on IAPI risk prediction model in Chinese and English databases such as CBM,CNKI,PubMed and Web of Science were searched.The language is limited to Chinese and English,and the search time is until November 4,2022.Two researchers independently screened the literature and extracted the data,and applied the bias risk assessment tool of prediction model research to analyze the bias risk and applicability of the included literature.Results 13 articles were included,including 17 models(operation time,age,diabetes,BMI and serum albumin are the most commonly used predictors).Among the 17 models,the area under the curve of 14 models was 0.616 to 0.984,and the other study did not report the AUC results.Among the 13 studies,10 had good applicability,while the remaining 3 had unclear applicability.13 studies have a high risk of bias,mainly because the included studies are retrospective studies,the predictive factors are screened based on univariate analysis,and the predictive outcomes are not defined by guidelines or standardization.Conclusions The existing IAPI risk prediction model for adults has good applicability,but the risk of bias is high,and the construction is not perfect.It is necessary to pay attention to the effectiveness of different risk assessment methods in the later construction,so as to get a better and more accurate risk prediction model and provide some reference and basis for formulating relevant prevention strategies.

Objective To use the cognitive reinforcement comprehensive intervention program constructed by our team to intervene in patients with spinal cord injury and evaluate its clinical application effect.Methods A non-randomized trial design was adopted to select 97 patients with spinal cord injury from November 2021 to September 2022.Forty-four patients from March to September 2022 in a Grade A hospital in Hefei City were included in the experimental group,and 53 patients from November 2021 to February 2022 were included in the control group.The cognitive reinforcement comprehensive intervention program was used to intervene in the experimental group,and the conventional rehabilitation nursing was used to intervene in the control group.The intervention lasted for 12 weeks in both groups.The Changsha Montreal Scale,Social Support Rating Scale,Rehabilitation Exercise Self-efficacy Scale,Spinal Cord Injury Independence Rating Scale and Hamilton Anxiety Scale were used to measure the two groups before intervention,1 month after intervention and 3 months after intervention.Results 40 cases in the experimental group and 48 cases in the control group completed the study.Repeated measurement ANOVA showed that the temporal,interactive and intergroup effects of cognitive function scores and anxiety scores were statistically significant(P＜0.05).The time effect and interaction effect of the subjective support dimension score,coping self-efficacy dimension score of the two groups were statistically significant(P＜0.05).One month after the intervention,the cognitive function scores of test group were higher than before intervention and control group,and the anxiety scores were lower than before intervention and control group(P＜0.05).Three months after the intervention,the scores of cognitive function,subjective support dimension and coping self-efficacy dimension of experimental group were higher than those before intervention and control group,and the scores of anxiety level were lower than those before intervention and control group(P＜0.05).Conclusion Comprehensive intervention of cognitive reinforcement can improve the cognitive function of patients with spinal cord injury,delay the process of cognitive impairment,enhance self-confidence,relieve anxiety,and promote physical and mental rehabilitation of patients.
