Objective:To evaluate the validity and reliability of Negative Beliefs about Rumination Scale(NBRS)in Chinese college students.Methods:A total of 1004 college students were selected.Exploratory factor a-nalysis,criterion validity and internal consistency reliability test were performed on sample 1(n=501),Ruminative Responses Scale(RRS),Negative Beliefs about Uncontrollability and Danger of Worry(NEG)and the Beck De-pression Inventory-Ⅱ(BDI-Ⅱ)were used as criteria for criterion validity test.Confirmatory factor analysis and measurement invariance across gender were performed on sample 2(n=503).Totally 199 college students in total sample were retested 6 weeks later.Results:The exploratory factor analysis showed that there were 11 NBRS items with 3 factors,which explained 63.75％of the total variance.The confirmatory factor analysis showed that the 3-factor model fitted well(x2/df=2.59,CFI=0.97,TLI=0.95,SRMR=0.04,RMSEA=0.06).The NBRS scores were positively correlated with the scores of RRS,NEG and BDI-Ⅱ(ICC=0.59,0.75,0.53;Ps＜0.01).The Cronbach's α coefficient of the NBRS was 0.82,and the retest reliability(ICC)was 0.74.The configural,weak,strong and strict invariance of the NBRS across gender were all acceptable(△CFI＜0.01,△TLI＜0.01).Conclu-sion:The Negative Beliefs about Rumination Scale demonstrates good validity and reliability in Chinese college students,making it a useful tool for research and interventions related to rumination.

Objective:To investigate the application effect of team-based learning (TBL) versus lecture-based learning (LBL) in the first aid skill training of peacekeeping forces.Methods:A total of 326 officers and soldiers who had not participated in first aid skill training from various peacekeeping units in the Gao area of the Eastern Theater of United Nations Multidimensional Integrated Stabilization Mission in Mali from September 2022 to June 2023 were selected and divided into groups A and B using numerical randomization, with 163 individuals in each group. The individuals in group A received LBL teaching, and those in group B received TBL teaching. Questionnaire survey, theoretical assessment, and operational skill assessment were performed for all officers and soldiers after the end of the course. SPSS 19.0 was used for the t-test and the chi-square test. Results:Compared with the LBL group, the TBL group had significantly better first aid awareness, first aid skills, team collaboration ability, and humanistic concern and a significantly higher degree of satisfaction with the training mode. The LBL group had a slightly higher theoretical assessment score than the TBL group [(86.73±8.57) vs. (85.92±7.66)], with no significant difference between the two groups. Compared with the LBL group, the TBL group had significantly better scores of each operational skill and the total score of operational skill assessment [(86.71±11.25) vs. (81.14±10.05)].Conclusions:As a relatively effective training mode, the TBL teaching method has significant advantages in improving the first aid awareness, team collaboration ability, and practical operation ability of peacekeeping personnel, and therefore, it holds promise for application in Mali and other peacekeeping task areas.

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.

Trauma can disrupt the body′s internal environment, resulting in organ dysfunction. This may manifest as symptoms such as acute respiratory distress, liver and kidney dysfunction, circulatory disorders and neurological damage. Mitochondrial quality control (MQC), encompassing processes like autophagy, dynamic changes, and biogenesis, plays an essential role in maintaining mitochondrial function. Stress responses following trauma can cause mitochondrial dysfunction and MQC imbalance, thereby exacerbating organ injury. Correcting MQC imbalance can improve organ function. Current researches on MQC in post-traumatic organ dysfunction mainly focuses on imbalance in specific MQC mechanism, lacking a systemic understanding of its incidence and progression. To this end, the authors reviewed the progress in researches on the impact of MQC imbalance on post-traumatic organ dysfunction, aiming to provide insights for clinical treatment.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Background::Growth differentiation factor-15 (GDF-15) is a stress response protein and is related to cardiovascular diseases (CVD). This study aimed to investigate the association between GDF-15 and pre-eclampsia (PE).Method::The study involved 299 pregnant women, out of which 236 had normal pregnancies, while 63 participants had PE. Maternal serum levels of GDF-15 were measured by using enzyme-linked immunosorbent assay kits and then translated into multiple of median (MOM) to avoid the influence of gestational week at blood sampling. Logistic models were performed to estimate the association between GDF-15 MOM and PE, presenting as odd ratios (ORs) and 95% confidence intervals (CIs).Results::MOM of GDF-15 in PE participants was higher compared with controls (1.588 vs. 1.000, p < 0.001). In the logistic model, pregnant women with higher MOM of GDF-15 (>1) had a 4.74-fold (95% CI= 2.23-10.08, p < 0.001) increased risk of PE, adjusted by age, preconceptional body mass index, gravidity, and parity. Conclusions::These results demonstrated that higher levels of serum GDF-15 were associated with PE. GDF-15 may serve as a biomarker for diagnosing PE.
