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 develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

Objective:To analyze the protective effect of a respiratory syncytial virus (RSV) vaccine based on bacterial outer membrane vesicle (OMV) in mice.Methods:The pre-fusion protein (preF) of RSV was linked to the surface of OMV through the transmembrane protein cytolysin A (ClyA) to form the nanovaccine OMV-preF. The morphological characteristics of OMV and OMV-preF were observed under a transmission electron microscope. OMV-preF was intramuscularly injected into BALB/c mice and the elicited humoral and cellular immune responses were evaluated. The protective effect of OMV-preF was assessed by challenging the immunized mice with RSV Long strain. One-way analysis of variance and Tukey test were used for statistical analysis.Results:The results showed that preF was stably expressed in OMV, and both OMV-preF and OMV exhibited a double-layer vesicle structures under the microscope. OMV-preF could significantly activate the cellular and humoral immune responses in mice, causing a significant increase in CD8 + T cells and CD19 + B cells as well as a significant increase in the serum level of specific IgG. The neutralizing antibodies produced in the immunized mice could significantly inhibit the replication of RSV Long strain in vivo. Conclusions:The nanovaccine OMV-preF can induce high-level humoral and cellular immune responses, and the antibodies produced following immunization can effectively inhibit viral replication. This study provides a new strategy for RSV subunit vaccines.

OBJECTIVE: To compare the clinical efficacy of jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training for post-stroke spastic paralysis. METHODS: A total of 60 patients with post-stroke spastic paralysis were randomly divided into an observation group and a control group, 30 cases in each one. Both groups received conventional rehabilitation training. In the observation group, jingjin needling was applied at tendon blockage points of the shoulder, elbow, wrist, hip, knee, and ankle. In the control group, conventional acupuncture was applied at Jianyu (LI15), Quchi (LI11), Hegu (LI4), Biguan (ST31), Fengshi (GB31), Taichong (LR3), etc. on the affected side. Treatment was given once daily, 5 days a week for 4 weeks in both groups. The scores of clinical spasticity index (CSI), modified Ashworth scale, modified Barthel index (MBI), and Fugl-Meyer assessment scale (FMA) were evaluated before and after treatment, and the onset time was compared between the two groups. RESULTS: After treatment, the scores of CSI and modified Ashworth scale were decreased compared with those before treatment (P<0.001), while the scores of MBI and FMA were increased compared with those before treatment (P<0.001) in the two groups. After treatment, the scores of CSI and modified Ashworth scale in the observation group were lower than those in the control group (P<0.05), the MBI score in the observation group was higher than that in the control group (P<0.05). There was no statistically significant difference in FMA scores between the two groups (P>0.05). The onset time of the observation group was earlier than that in the control group (P<0.05). CONCLUSION Both jingjin needling combined with rehabilitation training and conventional acupuncture combined with rehabilitation training can effectively treat post-stroke spastic paralysis, jingjin needling combined with rehabilitation training exhibits better therapeutic effect and rapider onset.

RNA binding motif protein 8A(RBM8A)is an RNA binding protein,which is mainly in-volved in translation and cell cycle regulation.In addition,RBM8A is a core factor of the exon-junc-tion complex(EJC),which is highly expressed in cells,especially in cancer cells,and abnormally expressed in cytoplasm and nucleus.Studies have shown that RBM8A plays a key regulatory role in the replication process of some viruses,such as Flaviviridae viruses.Therefore,whether RBM8A is involved in the replication of pseudorabies virus(PRV)is unknown.Therefore,this study proved whether RBM8A is involved in the replication of PRV.In order to study the effect of RBM8A pro-tein on PRV replication,the eukaryotic expression plasmid pCAGGS-HA-RBM8A was designed and constructed to express RBM8A,and sh-RBM8A was simultaneously designed and constructed to overexpress and inhibit RBM8A.qRT-PCR and Western blot were used to detect the effect of RBM8A on PRV replication.At the same time,PRV-GB standard plasmid was constructed to make PRV proliferation standard curve.After overexpression and inhibition of RBM8A,DNA was ex-tracted.Virus copy number was calculated by qRT-PCR to further detect the effect of RBM8A on PRV replication.The results showed that overexpression of RBM8A inhibited PRV replication and decreased the copy number of the virus,while overexpression of shRBM8A promoted PRV replication and increased the copy number of the virus.This study shows that RBM8A can inhibit PRV replication,which provides reference for the functional study of RBM8A and lays a founda-tion for the mechanism of anti-PRV replication.

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.
