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 establish the fingerprints and predict the quality markers of Sanqi Shenfeng oral liquid based on fingerprint and network pharmacology.Methods The fingerprints of 12 batches of Sanqi Shenfeng oral liquid were established by using HPLC,and their peaks were identified and assigned.The candidate components were selected by multiple statistical analysis methods such as similarity evaluation,hierarchical cluster analysis,principal component analysis and orthogonal partial least squares discrimination analysis(OPLS-DA).The"component-target-pathway"network diagram was constructed by network pharmacology,and the quality markers of Sanqi Shenfeng oral liquid were predicted.Results The 13 common peaks were identified from the established fingerprint.Compared with the reference material,eight common peaks were identified as 3(tetrahydroxystilbene glucoside),5(sodium benzoate),6(lobetyolin),7(notoginsenoside Ri),9(ginsenoside Rgi),10(ginsenoside Re),12(10-hydroxy-2-decenoic acid),13(ginsenoside Rb1).The similarity of 12 batches of Sanqi Shenfeng oral liquid samples was higher than 0.997,and 12 batches of samples were grouped into two categories.OPLS-DA analysis showed that peaks 2,3,4,7,9,10,11,12 were the main signature components affecting the quality of Sanqi Shenfeng oral liquid.Network pharmacology predicted that lobetyolin,notoginsenoside R1,ginsenoside Rg1,ginsenoside Rb1,ginsenoside Re and 10-hydroxy-2-decenoic acid were potential Q-markers of Sanqi Shenfeng oral liquid.The traditional functions are performed through STAT3/AKT1-Drp1,HIF-1 and PI3K-AKT signaling pathway.Conclusion The established fingerprint has good reproducibility,stability and feasibility.The six components have great influence on the quality of Sanqi Shenfeng oral liquid,which are transferable and traceable,and are closely related to the efficacy.They can be used as potential quality markers to provide a scientific basis for the quality control and evaluation of Sanqi Shenfeng oral liquid.

Acute pancreatitis (AP) is a life-threatening gastrointestinal disorder for which no effective pharmacological treatments are currently available. One of the pharmacological targets that merits further research is the neurokinin 1 receptor (NK1R), which is found on pancreatic acinar cells and responds to the neuropeptide substance P (SP) that participates in AP. Although a few studies have stated the involvement of SP/NK1R in neurogenic inflammation in AP development, the regulatory mechanism remains unclear. In this study, we found that following activation of NK1R by SP, β-arrestin1, a scaffold protein of NK1R, down-regulated transcription of Adss, Adsl, and Ampd in the purine nucleotide cycle, thereby inhibiting mitochondrial function through fumarate depletion. Interestingly, we identified magnolol as a new and natural NK1R inhibitor with a non-nitrogenous biphenyl core structure. It exhibited a beneficial effect on AP by restoring purine nucleotide cycle metabolic enzymes and fumarate levels. Our study not only provides new therapeutic strategies, leading compounds, and drug translation possibilities for AP, but also provides important clues for the study of downstream mechanisms driven by SP in other diseases.

Objective To evaluate the reliability and validity and perform cost-consequence analysis of the brief version of the Montreal cognitive assessment(MoCA)for identifying cognitive impairment in a community-based population ≥50 years of age.Methods The internal consistency and retest reliability of the brief version of the MoCA were analyzed,and the area under the curve(AUC),sensitivity,and specificity were determined to discriminate mild cognitive impairment(MCI)and dementia with the clinical dementia rating(CDR)as the diagnostic criterion.The consistency between the brief version and the full version was analyzed by the Kappa test and the Bland-Altman method,and the number of individuals entering the diagnostic assessment and the overall assessment time were estimated and compared between the two versions.Results A total of 303 individuals were included in this study,of whom 192,94,and 17 had normal cognitive function,MCI,and dementia,respectively.The Cronbach's α and re-test coefficients of the brief version of MoCA were 0.754 and 0.711(P<0.001),respectively.The brief version showed the AUC,sensitivity,and specificity of 0.889,74.5%,and 93.8% for identifying MCI,and 0.994,100%,and 93.8% for identifying dementia,respectively.When the brief version of MoCA was used to identify 94 patients with MCI in 303 individuals,107 individuals required additional diagnostic assessment,with an overall assessment time of 142.4 h,which represented decreases of 21.3% and 32.7%,respectively,compared with those of the full version.When the brief version of MoCA was used to identify 17 patients with dementia in 303 individuals,35 individuals required additional diagnostic assessment,with an overall assessment time of 70.4 h,a decrease of 29.5% in the time cost compared with the full version.Conclusions The brief version of MoCA can identify cognitively impaired individuals in a community-based middle-aged and elderly population,with diagnostic validity comparable to that of the full version but less time cost and fewer individuals needing additional diagnostic assessment to detect true-positive cases.It could be expanded for use in the community-based primary screening setting.
