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.

OBJECTIVE: To compare effectiveness of injecting platelet-rich plasma (PRP) with different concentrations of leukocytes under ultrasound in treatment of supraspinatus tendon injury. METHODS: A clinical data of 30 patients with supraspinatus tendon injury, who met the selection criteria and were admitted between December 2022 and December 2023, was retrospectively analyzed. Thirty patients were treated with 4 injections of leukocyte-poor PRP (LP-PRP, n=10), leukocyte-rich PRP (LR-PRP, n=11), and triamcinolone ( n=9), with an interval of 7-10 days between each injection. There was no significant difference between groups ( P>0.05) in the age, gender, disease duration, affected shoulder side, Ellman classification, preoperative visual analogue scale (VAS) score, Constant score, Disabilities of the Arm, Shoulder, and Hand (DASH) score, and American Shoulder and Elbow Surgeons (ASES) score. At 1, 3, and 6 months after injection, the shoulder pain and function were evaluated by using the VAS score, Constant score, DASH score, and ASES score. MRI was conducted to observe supraspinatus tendon healing. RESULTS: No severe adverse reactions was observed in all groups. All patients were followed up 6-7 months, with an average of 6.5 months. After injection, the ASES score and Constant score gradually increased in the LR-PRP group and LP-PRP group, while the VAS score and DASH score decreased, with significant differences compared to before injection ( P<0.05). Except for no significant difference between 3 and 6 months after injection in LR-PRP group ( P>0.05), the above scores showed significant differences between different time points ( P<0.05). At 1 month after injection, the Constant score in triamcinolone group significantly increased compared to before injection, while the VAS score significantly decreased ( P<0.05). There was no significant difference in all scores between other time points in the triamcinolone group ( P>0.05). Except for 1 month after injection, there was no significant difference in Constant score and VAS score between groups ( P>0.05). At all other time points, the LR-PRP group and LP-PRP group had better scores than the triamcinolone group ( P<0.05). There was no significant difference between the LR-PRP group and the LP-PRP group ( P>0.05). MRI showed that only 4 patients in the LP-PRP group had signs of repair at the supraspinatus tendon injury site at 6 months after injection, while no significant tendon repair sign was observed in the other patients. CONCLUSION Compared with triamcinolone treatment, multiple injections of LP-PRP and LR-PRP under ultrasound can promote the recovery of shoulder joint function and significantly relieve pain in patients with supraspinatus tendon injury, and imaging improvement can be seen after LP-PRP treatment.

Objective:To explore the feasibility in reconstruction of the muscular power with the superficial part of lateral femoral muscle through anatomical study on the superficial region of lateral femoral muscle.Methods:Studies on 4 sides of lower limbs of 2 cadaver specimen were conducted in the Department of Hand and Foot Microsurgery of Xi'an Fengcheng Hospital. Intraoperative observations and measurements were further carried out on 21 sides of 21 patients. Muscular fascia in superficial region, muscular gross morphology, thickness, length and width of muscles, length of muscle fibres and pinnate angles of muscle surface were observed and measured. Both blood vessels and nerves in the muscle were separated to measured.Results:The superficial region of lateral femoral muscle was in a shape of fusiform and started from the greater trochanter and ended at the patella and rectus femoris, with the fascia at proximal end and the muscle of distal end. The inferior muscle fibres of the fascia were arranged in sequence and ended at the deep fascia from proximal to distal. Mean muscle thickness was measured at 1.96 cm±0.48 cm, and mean pinnate angle was of 18.9°±3.3°. The superficial region was found being distributed by the descending branches of lateral circumflex femoral artery(LCFA) and the second branch of femoral nerve, and they accompanied each other. At 5.0 cm from the point of entry to the muscle, the diameter of the vessels was measured at 2.39 mm±0.52 mm, and the diameter of nerves was at 2.64 mm±0.61 mm. Both of arteries and nerves further branched out anteriorly and posteriorly in 1.0-1.5 cm intervals after having entered the muscle. At 0 - 2.5 cm away from the muscle entry point, a larger branch was often running posteriorly into the muscle, and this branch appears on all 4-sided specimens. While the occurrence rate in the 21 sides of patients observed in operations was of 90.5%, with a transverse diameter at 1.23 mm±0.28 mm.Conclusion:The superficial region of lateral femoral muscle is dominated by independent vessels and nerves and there are many branches from superior vessels and nerves, which form an anatomical basis for one or more muscular flaps.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Objective:To analyze the application effect of the information platform based on the Internet of Things (IoT) in the screening and management of patients with chronic obstructive pulmonary disease (COPD).Methods:In this cross-sectional study, 151 062 residents who participated in the screening in the districts covered by 33 general hospitals and 289 primary medical institutions within the framework of Henan Provincial Center for COPD Prevention and Treatment from November 2021 to October 2022 were included as the subjects. Spirometer based on the IoT was used to conduct pulmonary function tests for subjects who scored 16 points or more with COPD Screening Questionnaire (COPD-SQ), and the subjects were evaluated and managed through the structured electronic data in the information platform. The distribution characteristics and follow-up of the subjects and COPD patients were described and the application effect of this strategy in patients screening and management was analyzed.Results:A total of 151 062 residents with complete basic information in the information platform completed the questionnaire. High-risk population of COPD accounted for 26.5% (40 042/151 062) of the population who received the questionnaire screening, and more than 50% had respiratory symptoms, such as chronic cough (59.4%), or shortness of breath (77.6%). The proportion of high-risk population increased with age, especially after 50 years old. Compared with non-smokers, the proportion of high-risk group was significantly higher (77.1% vs 16.4%) in the group with smoking index over 600. Biofuel exposure (61.3% vs 22.1%) and family history of respiratory diseases (64.2% vs 22.6%) were associated with an increased proportion of high-risk groups, with statistically significant differences ( P<0.001). 5 268 patients were diagnosed with COPD by pulmonary function tests, and the prevalence of COPD in high-risk groups was 27.8% (5 268/18 965), the prevalence rate of male was 34.0% (3 942/11 588), which was higher than that of female 18.0% (1 326/7 377). 2 950 patients (56.0%) completed at least one follow-up of symptom questionnaire and 510 patients (9.7%) completed more than one follow-up of pulmonary function test. Conclusion:The screening and management strategy of COPD based on the IoT and information technology can improve the efficiency of COPD screening, and improve the status quo of under-diagnosis and discontinuous follow-up of COPD.

Objective:To investigate the effect of free anterolateral thigh perforator flap in repair of forefoot injuries combined with multiple tissue defect.Methods:A retrospective case series study was conducted on 26 patients who suffered from forefoot injuries combined with multiple tissue defect admitted to 920th Hospital of Joint Logistic Support Force of PLA from January 2015 to December 2019. There were 21 males and 5 females, aged 15-61 years [(31.6±12.5)years]. The combined injuries were fracture in 10 patients, arsometatarsal joint dislocation in 3, bone defect in 9, tendon injury in 5, and ligament injury in 3. Management of multiple tissue defect of the forefeet: soft-tissue defect of the forefeet was resurfaced with free anterolateral thigh perforator flaps with the dimension of 6.0 cm×3.5 cm to 26.5 cm×10.0 cm; fracture was fixed by Kirschner wires; joint dislocation was treated by open reduction and Kirschner wires fixations; bone defect was reconstructed either by one-stage bone graft or by use of membrane-induced technique and secondary bone graft, according to the wound conditions; tendon injury of extensor digitorum longus was repaired by direct tendon suture or by tendon transfer; tarsometatarsal ligament injury was primarily sutured. The flap survival rate was observed within 2 weeks after operation. The fracture healing, bone-defect repair, foot appearance, and donor-site healing were detected at 1 month, 3 months, 6 months, 1 year post-operatively and at the last follow-up. The postoperative complications were recorded. The foot function was assessed using American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score before operation and at the final follow-up.Results:All patients were followed up for 6-36 months [(20.5±4.6)months]. All flaps survived uneventfully. The fracture healing and bone defect repair were acquired. The flap showed good texture, including primary flap thinning in 11 patients and secondarily thinning in 15 patients at 3-6 months postoperatively. The donor sites showed good healing, leaving only a linear scar. The flap venous crisis developed in 1 patient and survived after emergency vascular exploring. Local infection of flap occurred in 3 patients and was cured after further debridement and the use of sensitive antibiotics. The AOFAS ankle-hindfoot score was 54-94 points [(76.6±10.4)points] at the last follow-up, compared to preoperative 11-51 points [(27.2±11.3)points] ( P<0.01). The results were excellent in 5 patients, good in 11, and fair in 10, with the excellent and good rate of 62%. Conclusions:For forefoot injuries combined with multiple tissue defect, anterolateral thigh perforator flap transplantation with additional techniques to treat fractures, bone defect, tendon and ligament injuries can achieve satisfactory results in aesthetic appearance of the flap and donor site and foot function recovery.

AIM: To observe the effect of acute normovolemic hemodilution (ANH) autologous blood transfusion on the EEG bispectral index and muscle relaxation in elderly patients undergoing orthopedic surgery to explore the influence of autologous blood transfusion containing anesthetic components on the quality and safety of postoperative anesthesia recovery. METHODS: Forty patients, aged 65-75, weighing 55-80 kg, ASA grade I-II, with an estimated intraoperative blood loss of more than 600 mL, were selected for elective orthopedic surgery. The patients were randomly divided into two groups (n=20): group A was given acute normovolemic hemodilution (ANH), and the target value of Hct was 28%-30% after induction of anesthesia; group B was the control group which was given routine fluid infusion during operation without ANH. Bispectral index (BIS), TOF values and plasma concentrations of propofol and cisatracurium were measured at the beginning of autotransfusion (T

Objective To evaluate the effect of different hemoglobin(Hb)concentrations on the lung injury in a rabbit model of hemorrhagic shock and resuscitation(HS-R).Methods Fifty healthy male New Zealand rabbits,aged 2 months,weighing 1.9-2.4 kg,were divided into 5 groups(n＝10 each)u-sing a random number table method: control group(group C),HS-R group(group H),and three HS-R plus infusion of concentrated red blood cell groups group R1(60 g/L≤Hb＜80 g/L),group R2(80 g/L≤Hb＜100 g/L)and group R3(100 g/L≤Hb＜120 g/L).The animals were sacrificed at 3 h after resuscita-tion,lung tissues were obtained for examination of the pathological changes with a light microscope,and lung tissues were obtained again for determination of wet to dry weight ratio(W/D ratio),neutrophil my-eloperoxidase(MPO),NO level and cell apoptosis(by TUNEL).Results Compared with group C,the levels of MAP and NO,W/D ratio and apoptosis index were significantly increased in the other groups(P＜0.05).Compared with group H,the levels of MAP and NO,W/D ratio and apoptosis index were signifi-cantly decreased in R2 and R3 groups(P＜0.05).Compared with group R2,the apoptosis index was signif-icantly increased at T5(P＜0.05),and no significant change was found in the other parameters in group R3(P>0.05).Conclusion Maintaining Hb 80-100 g/L after HS-R reduces acute lung injury in rabbits.
