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.

Lipid rafts are microdomains in the cell membrane that are involved in cell signal transduction,metabolism,and intercellu-lar interactions.In recent years,studies have shown that lipid rafts play an important role in the pathogenesis of diabetes.Cholesterol and sphingolipids are the main lipid components in lipid rafts,and the protein components in lipid rafts include caveolin,flotillin,pal-mitoylated proteins,and glycosylphosphatidylinositol-anchored proteins.Changes in these components affect the structure and function of lipid rafts,which in turn may affect insulin signal transduction,leading to the occurrence of diabetes-related diseases.Lipid rafts are closely related to the occurrence and development of diabetes in different tissues.Pancreatic lipid rafts are closely related to insulin se-cretion,and their structural changes affect insulin synthesis and release.Changes in lipid rafts in adipose tissue are related to insulin resistance and disorders of glycolipid metabolism.Changes in lipid rafts in the liver can affect gluconeogenesis and glycogen synthesis.Lipid rafts in the kidney play a regulatory role in the progression of diabetic nephropathy.This article aims to provide a comprehensive overview of the role of lipid rafts in the pathogenesis of diabetes,offering insights into the identification of new targets for the prevention and treatment of diabetes in the future,as well as presenting a new perspective for the development of therapeutic agents for diabetes.

Objective To explore the application of bundled nursing care for recurrent obstruc-tive esophageal cancer treated by photodynamic therapy.Methods Thirty patients with recurrent ob-structive esophageal cancer were administered with photosensitizer hematoporphyrin derivative injec-tion.After 24 hours,an optical fiber was introduced under endoscopic guidance,and 630 nm laser was used to irradiate the tumor locally.The degree of relief in dysphagia,improvement in perform-ance status,changes in body mass index,and treatment-related adverse reactions were recorded.Bundled nursing strategies were implemented,including preoperative assessment,education,prepara-tion,postoperative positioning,observation,prevention of complications,and light protection meas-ures.Results After treatment,the median diameter of the narrowest esophageal lesion was increased[(8.92±0.64)mm versus(4.77±0.60)mm],the Karnofsky Performance Status(KPS)score was improved[(77.69±5.99)versus(84.62±6.60)],BMI was increased[(17.17±1.66)kg/m2 ver-sus(18.08±1.60)kg/m2],and the Stooler dysphagia grade was decreased compared with treatment be-fore.The main treatment-related adverse reactions were retrosternal pain and fever.Conclusion Photo-dynamic therapy for recurrent obstructive esophageal cancer has a rapid onset of action and mild ad-verse reactions,and ensures the smooth implementation of PDT and patients'safety.

Objective:To investigete the relationship between different physical activity(PA)and bone mineral density(BMD)at various skeletal sites,providing evidence for the prevention and improvement of bone health.Methods:Cross-sectional data from the National Health and Nutrition Examination Survey(NHANES)from 2007 to 2018 was used,and 7 692 participants aged≥20 were included.Multivariable linear regression model was used to analyze the relationship between different PA and BMD at the femoral neck,total hip,and lumbar spine across different genders.Statistical modeling employed a sequential variable inclusion approach:Model 1 included age,race/ethnicity,and body mass index,while Model 2 further incorporated calcium intake,marital status,smoking status,dietary inflammatory index,and serum phosphate levels.Results:PA showed statistically significant differences across age,gender,body mass index,race,marital status,smoking,and dietary inflammatory index(P＜0.05).Among females,low-intensity PA showed a positive association with femoral neck BMD in both Model 1 and Model 2(P＜0.05),but no significant correlation was found between low-intensity PA and total hip BMD(P＞0.05).High-intensity PA exhibited an inverse association with femoral neck and total hip BMD(P＜0.05),though this was only observed in Model 1.No significant association was detected between different PA intensities and lumbar spine BMD(P＞0.05).Among males,high-intensity PA showed a positive correlation with lumbar spine BMD(P＜0.05),but this association was only significant in Model 2.No significant association were observed between low-intensity PA and lumbar spine BMD in either Model 1 or Model 2(P＞0.05).Additionally,no significant association were found between different PA intensities and femoral neck or total hip BMD(P＞0.05).Conclusions:The relationship between PA and BMD varies by sex and skeletal site.Low-intensity PA is positively associated with femoral neck BMD in females,while high-intensity PA is positively correlated with lumbar spine BMD in males.

Objective To explore the protective effects of pretreatment with the Mongolian medicine Jiruhen Gurigumu-7(JG-7)and Guangzao Sanwei Tang(GZ-3)on myocardial ischemia-reperfusion injury(MIRI)in mice.Methods 60 male C57BL/6J mice were randomly divided into sham operation(Sham)group,model(Model)group,compound danshen drip pill(CDDP)positive control group,JG-7 group,GZ-3 group,and 12 mice in each group to establish the MIRI model,and the H9C2 cells were randomly divided into Control(normoxic)group,H/R(hypoxia 6 h reoxygenation 14 h)group,H/R+JG-7 group,H/R+GZ-3 group.The mice in each group were tested for cardiac function indexes after 30 min of ischemia,24 h and 7 d of reperfusion,TTC staining to detect infarct area after 24 h of MIRI,HE staining to detect myocardial tissue structure and cellular morphology after 24 h of MIRI,TUNEL apoptosis kit to detect apoptosis of myocardial cells after 24 h of MIRI,Masson staining to detect myocardial fibrosis after 7 d of MIRI.Blood was taken from the abdominal aorta,serum was separated,and the indexes after oxidative stress of MIRI were detected in each group of mice,and the survival rate of H9C2 cells after H/R was detected in each group by CCK-8 method.Results The results of TTC showed that JG-7 and GZ-3 reduced the infarct area after 24 h of MIRI in mice.ELISA and kit assays proved that JG-7 and GZ-3 reduced creatine phosphokinase isoenzyme(Creatinekinase-MB,CK-MB),Lactic dehydrogenase(LDH),malondialdehyde(MDA)levels,and increased superoxide dismutase(SOD)levels.HE staining showed that JG-7 and GZ-3 improved myocardial pathology after MIRI 24 h.The results of TUNEL apoptosis assay showed that JG-7 and GZ-3 improved apoptosis in myocardial tissues 24 h after MIRI.Masson staining results showed that JG-7 and GZ-3 could reduce the area of myocardial tissue fibrosis after MIRI 7 d.CCK-8 assay results showed that JG-7 and GZ-3 could improve the cell survival rate after H/R in H9C2 cells.Conclusion Pre-treatment with Mongolian medicine Jiruhen Gurigumu-7 and Guangzao Sanwei Tang can reduce the damage caused after ischemia-reperfusion(I/R),decrease the area of myocardial infarction and fibrosis after I/R in mice,and protect the heart.

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.

Objective To explore the effect of sleep duration and body mass index(BMI)on hypertension.Methods The data was collected from the database of the China Health and Retirement Longitudinal Study(CHARLS),and the data of the 2015 National Longitudinal Study were selected.A total of 8,889 subjects were included in this study.Questionnaires,health status,physical examination and laboratory information were collect-ed.The interactive effect of sleep duration and BMI on hypertension was analyzed by multiplicative model and addi-tive model.Results The prevalence rate of hypertension was 28.86%.Logistic regression results showed that night sleep duration＜6 h(OR=1.138,95%CI:1.024-1.265)and＞8 h(OR=1.1365,95%CI:1.167-1.598);overweight(OR=1.736,95%CI:1.557-1.936)and obesity(OR=2.076,95%CI:1.973-2.710)were all risk factors for hypertension(P＜0.05).Stratified results showed that the risk of hypertension in the normal group was 1.193(95%CI:1.023-1.393)times and 1.555(95%CI:1.244-1.943)times of those with sleep du-ration 6-8 h,respectively.The risk of hypertension was 1.392(95%CI:1.066-1.818)times higher than that of sleep duration 6-8 h.The interaction showed that night sleep duration and BMI had a multiplicative interaction(OR=2.120,95%CI:1.767-2.543)and a additive interaction on hypertension[RERI=1.242(95%CI:0.326-2.157),SI=3.697(95%CI:2.658-5.143),AP=0.460(95%CI:0.324-0.595)].Conclusions Insufficient and excessive sleep duration at night and BMI both increase the risk of hypertension,and have a mul-tiplicative and additive interaction.Reasonable adjustment of nighttime sleep duration and BMI may prevent the occurrence of hypertension.
