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 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.

ObjectiveTo investigate the expression level of Golgi transport 1A （GOLT1A） in thyroid carcinoma and its effects on the proliferation， migration， invasion， and epithelial-mesenchymal transition （EMT） of thyroid carcinoma cells. MethodsThe expression of GOLT1A in thyroid carcinoma was analyzed online by tumor immune estimation resource （TIMER）， the University of Alabama at Birmingham cancer data analysis portal （UALCAN）， gene expression profiling interactive analysis 2 （GEPIA2）. The expression level of GOLT1A in thyroid carcinoma cells was detected by real-time fluorescence quantitative polymerase chain reaction （RTFQ-PCR） and western blot. Cell counting kit-8 （CCK-8） assay， colony formation assay， and transwell assay were used to detect the effects of GOLT1A expression on the proliferation， migration， and invasion of thyroid carcinoma cells. Western blot assay was used to detect the effect of GOLT1A on the expression of EMT-related genes including E-cadherin， vimentin， and N-cadherin. ResultsThe online analysis of GEPIA2， TIMER， and UALCAN showed that the expression of GOLT1A was higher in thyroid carcinoma than in normal tissues， and the expression of GOLT1A in thyroid carcinoma cells was significantly higher than in normal control cells. Knockdown of GOLT1A inhibited TPC1 cell proliferation， migration， and invasion. The expression of E-cadherin increased and the expressions of N-cadherin and vimentin decreased in GOLT1A knockdown TPC1 cells. Overexpression of GOLT1A promoted BCPAP cell proliferation， migration， and invasion. The expression of E-cadherin decreased and the expressions of N-cadherin and vimentin increased in GOLT1A overexpression BCPAP cells. ConclusionGOLT1A is highly expressed in thyroid carcinoma and can promote the proliferation， migration， and invasion of thyroid carcinoma cells.

Objective:To construct an evaluation indicator system for the efficiency of nursing human resources in integrated medical and elderly care institutions using Data Envelopment Analysis (DEA) and subsequently evaluate its effectiveness.Methods:This cross-sectional survey utilized literature review and investigative methods to initially establish a library of evaluation indicators for nursing human resource efficiency. The Delphi method was employed in two rounds of consultations with 17 experts from various fields, including nursing management, elderly care institution management, integrated medical and elderly care institution management, health economics management, and public health. The reliability of the indicator system was assessed based on factors such as expert enthusiasm, authority, concentration of opinions, and coordination. Adjustments, modifications, and improvements were made to the indicators based on expert opinions to establish the final indicator system. From August to December 2022, the DEA model was applied to evaluate the efficiency of 12 integrated medical and elderly care institutions in Haikou city based on this indicator system.Results:The constructed evaluation indicator system comprised 68 items divided into three levels: 9 primary indicators, 19 secondary indicators, and 40 tertiary indicators. The positive coefficients of the two rounds of expert consultations were 100% and 94.1%, with authority coefficients of 0.88 and 0.92, Kendall harmony coefficients of 0.471 and 0.348, and mean coefficients of variation of 0.16 and 0.12 ( P<0.001). DEA evaluation results for the 12 integrated medical and elderly care institutions showed that 5 were DEA effective institutions with comprehensive efficiency (OE), technical efficiency (TE), and scale efficiency (SE) values all equal to 1.000, while 7 were non-DEA effective institutions, including 4 with SE <1.000 but TE=1.000 and 3 with both SE and TE<1.000. Conclusions:The constructed evaluation indicator system demonstrates high enthusiasm, authority coefficients, and coordination in expert consultations, indicating high acceptability and comprehensive content with distinct levels and strong specialty characteristics. The DEA model′s evaluation results objectively and effectively reflect the efficiency of nursing human resources in integrated medical and elderly care institutions, demonstrating practical utility.
