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.

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 investigate the current situation of knowledge,belief,and practice of grass-root health workers during war injury rescue in marine corps,so as to provide a basis for targeted training of war injury rescue.Methods From March to May 2023,382 grass-root health workers were selected by convenience sampling method as research subjects,and a self-designed questionnaire was used for the survey.Results The average scores of knowledge,attitude,and behavior items related to war injury rescue were 3.78±0.94,4.55±0.64,and 3.50±1.08,respectively.Multiple linear regression analysis showed that military rank,workplace,and training experience were the main influence factors for the knowledge,belief,and practice of health workers in war injury rescue(P<0.05).Conclusion Grass-root health workers in the marine corps have a positive attitude towards war injury rescue,but their knowledge and practice are relatively weak.It is necessary to carry out targeted and graded training for them.

Objective:To observe the clinical efficacy of treating somatoform pain disorder(SPD)with electroacupuncture(EA)at the Governor and Conception Vessel points plus duloxetine.Methods:Eighty-two SPD patients were randomly allocated to an observation group and a control group,with 41 cases in each group.The control group was intervened by oral administration of duloxetine hydrochloride enteric capsules at a dose of 60 mg per time once a day;based on the medication,the observation group received additional EA treatment by selecting points from the Governor and Conception Vessels.Clinical efficacy was evaluated after 8 weeks of treatments;changes in the scores of the short-form McGill pain questionnaire(SF-MPQ),self-report symptom inventory,symptom check list-90(SCL-90),Pittsburgh sleep quality index(PSQI),and generic quality of life inventory-74(GQOLI-74)were also compared.Results:After the intervention,the observation group surpassed the control group in comparing the total effective rate(P＜0.05).The SF-MPQ score,SCL-90 somatization score,and PSQI score dropped notably in both groups after treatment,and the intra-group differences were statistically significant(P＜0.05);the three scores were significantly lower in the observation group than in the control group(P＜0.05).The GQOLI-74 score got an increase in each dimension in both groups after treatment,and the intra-group differences were also statistically significant(P＜0.05);the GQOLI-74 dimension scores were all significantly higher in the observation group than in the control group(P＜0.05).Conclusion:For patients with SPD,combining EA at the Governor and Conception Vessel points and duloxetine hydrochloride enteric capsules can markedly improve their clinical symptoms and quality of life.

In order to investigate developmental coordination disorder (DCD) of kindergarten children in Zhejiang province, 200 ordinary kindergartens were randomly selected by stratified random sampling in 11 prefecture-level cities of Zhejiang Province, and 38 900 children from 1 000 classes in each grade were then randomly selected into the study from June 2019 to December 2019. The Little DCD Questionnaire and a self-designed questionnaire were used to screen the DCD of those children. There were 36 807 valid questionnaires, and 6.50% (2 391/36 807) of them were positive results. The results showed that boy, age ≤5 years, overweight or obesity, left handedness, comorbidity with motor or developmental disorders and premature infants were risk factors of DCD in children. As for parents and families, maternal gestational age<20 years, maternal overweight or obesity before pregnancy, low-middle level education of parents, direct family and low income of family were also associated with DCD in children. Therefore, it is necessary to conduct early prevention and intervention strategies targeting on identified risk factors among relevant population.

Objective: To investigate the status and identify the influencing factors of smoking behaviors among residents in Nanshan District, Shenzhen City, so as to provide insights into tobacco control. Methods: Permanent residents at ages of more than 18 years were recruited from 17 communities in Nanshan District, Shenzhen City using the stratified multistage random sampling method from July to November, 2018. Participants' demographic features, smoking, smoking cessation and exposure to secondhand smoke were collected using the Individual Questionnaire for 2018 Chinese Adult Chronic Disease and Nutrition Surveillance. The factors affecting current smoking were identified using a multivariable logistic regression model. Results: Totally 1 700 questionnaires were allocated, and 1 625 valid questionnaires were recovered, with an effective recovery rate of 95.59%. The respondents included 714 men and 911 women, with a male to female ratio of 1∶1.27, and had a mean age of ( 45.13±13.59 ) years. The prevalence of current smoking was 15.51%, with 28.15% prevalence in men and 5.60% in women. The mean age of starting daily smoke was ( 21.00±5.52 ) years, and the mean daily smoking frequency was (13.53±9.15) cigarettes/d. The prevalence of smoking cessation was 6.58%, with 10.64% in men and 3.40% in women, and the prevalence of exposure to secondhand smoke was 41.42%, including 46.63% in men and 37.32% in women. Multivariable logistic regression analysis showed that an educational level of junior high school ( OR=1.683, 95%CI: 1.088-2.602 ), an educational level of high school/technical secondary school/vocational school (OR=1.687, 95%CI: 1.185-2.402), an occupation of farmers ( OR=2.514, 95%CI: 1.404-4.500 ), and an occupation of commercial and service personnel ( OR=1.939, 95%CI: 1.093-3.439 ) were associated with current smoking. Conclusion The prevalence of current smoking is low among residents in Nanshan District, but the prevalence of current smoking in women is higher than the national level. Educational level and occupation are main factors affecting current smoking.

Beh?et′s syndrome (BS) is classified among variable vessel vasculitis with unknown etiology and extensively heterogeneous clinical features. It is easily missed or misdiagnosed due to the lack of a specific laboratory diagnosis index. Based on the evidence and guidelines from China and other countries, the Chinese Rheumatology Association developed the standardization of diagnosis and treatment of BS. The purposes are: (1) To standardize the detection and interpretation of key indicators for BS; (2) To standardize rational management for BS patients with topical and systemic organ involvement to reduce complications and improve outcomes.

Along with the develoipment of high-throughput sequencing technologies, both sample size and SNP number are increasing rapidly in genome-wide association studies (GWAS), and the associated computation is more challenging than ever. Here, we present a memory-efficient, visualization-enhanced, and parallel-accelerated R package called"rMVP"to address the need for improved GWAS computation. rMVP can 1) effectively process large GWAS data, 2) rapidly evaluate population structure, 3) efficiently estimate variance components by Efficient Mixed-Model Association eX-pedited (EMMAX), Factored Spectrally Transformed Linear Mixed Models (FaST-LMM), and Haseman-Elston (HE) regression algorithms, 4) implement parallel-accelerated association tests of markers using general linear model (GLM), mixed linear model (MLM), and fixed and random model circulating probability unification (FarmCPU) methods, 5) compute fast with a globally efficient design in the GWAS processes, and 6) generate various visualizations of GWAS-related information. Accelerated by block matrix multiplication strategy and multiple threads, the association test methods embedded in rMVP are significantly faster than PLINK, GEMMA, and FarmCPU_pkg. rMVP is freely available at https://github.com/xiaolei-lab/rMVP.
