Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective:This study aimed to explore the clinical value of myostatin(MST) and follistatin(FST) as biological biomarkers in evaluating sarcopenia in elderly women.Methods:This was a retrospective cross-sectional study that enrolled 350 females aged 20-89 years who underwent physical examinations in Shanghai Huadong Hospital in 2021. Demographic characteristics, muscle mass, fat mass, bone mineral density, hand grip strength, gait speed, and serum indices of MST and FST were collected.Results:The serum levels of MST did not change significantly with age. However, the serum levels of FST increased with age. In women aged≥60 years, MST was positively correlated with total lean mass and appendicular skeletal muscle index(ASMI; r=0.236, P=0.041; r=0.289, P=0.014), while FST was negatively correlated with ASMI( r=-0.265, P=0.030). In multivariate stepwise regression analysis, after adjusting for age, body mass index, hip bone mineral density, and total fat mass, only FST was independently correlated with ASMI( β=-0.238, P=0.006), while MST was not correlated with ASMI. The receiver operating characteristic curve was plotted using muscle mass reduction as the state variable and serum FST level as the test variable. The area under the curve was 0.753. And when the FST cutoff value was 17.49 ng/mL, the maximum Jordan index was 0.46, with a sensitivity of 77.3% and a specificity of 68.7%. Women aged ≥60 years were divided into three groups based on serum FST levels. Compared to the upper third of the serum FST level group, the low third of the FST level group had a significantly reduced risk of suffering from sarcopenia( OR=0.098, P =0.036). Conclusions:Serum FST lever has a better correlation with muscle mass among elderly women, making it a promising biomarker for evaluating muscle mass.

Objective:To evaluate the effectiveness of Evidence-based Nursing Practice Guideline for Enteral Nutrition of Infants with Congenital Heart Disease application on improving the nutritional status of infants with congenital heart disease (CHD) in the target population, and to explore the effective strategies of evidence implementation in the process of dissemination, implementation and integration into clinical practice. Methods:This was an implementation study. Promoting Action on Research Implementation in Health Services Integrated Framework (i-PARIHS) was used as a theoretical model. Infants with CHD who received cardiac surgery from the heart ICU of Children ′s Hospital of Fudan University from January 2019 to February 2020 were selected as the study subjects. January to June 2019 and September to February 2020 were the pre and post implementation phase respectively. For medical staff, communication strategy, implementation process strategy, integration strategy and capacity-building strategy were used to advance the implementation process. According to the implementation strategy of children, the 26 best practice recommendations in the guide were translated into operable nursing processes and enteral nutrition programs, which were implemented in four stages: admission to the hospital, pre operation, post operation cardiac care room, post operation ward recovery, and pre discharge. Implementation Results Variable Assessment Form was used to evaluate effectiveness of the implementation strategies; hospitalization weight and upper arm circumference, serum albumin and pre-albumin before discharge were used to evaluate effectiveness of the interventions. Results:Scores of eight aspects of Implementation Results Variable Assessment reached more than 75% of the total score. Pre-albumin of post-implementation was (166.53 ± 42.57) g/L, which was statistically significantly higher than (148.41 ± 30.66) g/L before discharge ( t=-3.21, P<0.01); the weight loss of pre-implementation was 0.00 (0.41) kg, while the weight change of post-implementation was -0.10 (0.40) kg, the difference was statistically significant ( Z=-2.90, P<0.01). Conclusions:The strategies of diffusing, implementing, integrating the CHD enteral nutrition protocol based on guide could improve the implementation results and the nutrition status of infants with CHD.

Objective:Based on the Kirkpatrick model, construct an evaluation index system for the teaching effect of aseptic concept for interns in operating room.Methods:Based on the Kirkpatrick model as the theoretical framework, combined with literature review and group discussion, the first draft of the indicator system was drawn up, and the expert consultation questionnaire was compiled. 30 experts with nursing teaching experience from several tertiary hospitals and medical undergraduate colleges in Chengdu were selected for research. Delphi conducts 2 rounds of consultation with experts.

The final result index system for training nurses in operating room aseptic concept includes 4 first-level indicators, 11 second-level indicators, and 45 third-level indicators. Conclusion:The construction method of aseptic concept assessment index system for nursing students in operating room is scientific and reasonable, and the content is set appropriately, which can provide a basis for the evaluation of aseptic concept training for nursing students in operating room.

Through providing rhythmic stimulation to movement center, rhythmic auditory stimulation (RAS) may encourage hemiplegic patients to adjust movement pattern and external rhythm in time to improve the walking function after stroke. As an emerging intervention to treat the hemiplegic patients after stroke, RAS could effectively improve temporospatial gait parameters (gait velocity, stride length, cadence, and symmetry, etc.), joint movement pattern (angle of pelvis anterior tilt, and peak angle of knee flexion in mid-swing, etc.) and balance, which may be related to rhythmic entrainment movement system and the theory of auditory-movement synchronization. Simultaneously, frequency and dosage of RAS and the patient's lesions all have effect on the outcome of intervention.

Objective To observe the effect of a walking correcting tape on the kinematics and temporal-spatial indicators of gait after a stroke. Methods Thirty hemiplegic stroke survivors were randomly divided into a control group ( n=15) and a correcting tape group ( n=15) . In addition to their routine rehabilitation program, the control group received 30 minutes of walking training five times a week for 3 weeks with any necessary oral guidance and posture correction. The correcting tape group performed the same walking training assisted by a self-made walking correcting tape. Before and after the treatment, the kinematics and temporal-spatial indicators of both groups were quantified using three-dimensional gait analysis. Results After the treatment, the peak angles of hip and knee flex-ion were significantly higher in the taped group than in the control group and in the taped group before the treatment ( P≤0.05) . After the treatment, the walking speeds, stride frequencies and stride lengths of both groups were signifi-cantly better than before the treatment, but those of the former group were all significantly better than the latter ( P≤0.05 for both) . Conclusions Correcting tape can improve the peak angles of hip and knee flexion of hemiplegic legs and improve the walking capacity of stroke patients.
