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 evaluate the clinical value of 18F-fibroblast-activation protein inhibitor(18F-FAPI)PET/CT in malignant tumors exhibiting low uptake of 18F-fluorodeoxyglucose(18F-FDG).Methods We prospectively analyzed 62 patients with malignant tumors and low 18F-FDG uptake who underwent 18F-FAPI PET/CT in the Affiliated Cancer Hospital and Institute of Guangzhou Medical University from January 2021 to November 2022.Patient demographics information,clinical and radiological data were collected.Tumor lesions were categorized based on 18F-FAPI and 18F-FDG uptake relative to surrounding tissues into low-,moderate-,and high-uptake,with high uptake indicating positivity.The number and tracer uptake levels of primary tumors and metastatic lesions visualized by both 18F-FDG and 18F-FAPI were recorded and compared.Results Of the 62 primary tumors,18(29.0%)showed low-uptake and 44(71.0%)moderate-uptake on 18F-FDG PET,while 1(1.6%),6(9.7%),and 55(88.7%)showed low,moderate,and high uptake on 18F-FAPI,respectively.The maximum standardized uptake value(SUVmax)for primary tumors was significantly higher with 18F-FAPI than with 18F-FDG(7.5±5.6 vs.3.9±2.1,P<0.01).The number of positive lymph node foci revealed by 18F-FAPI was noticeably higher than that by 18F-FDG(77 vs.38,P<0.01).A total of 16 distant organ metastases were identified,with 11(68.8%)detected by 18F-FDG and 15(93.8%)by 18F-FAPI,showing no significant difference in detection rates(P>0.05).Conclusions 18F-FAPI PET/CT effectively visualizes primary and metastatic lesions in malignant tumors with low 18F-FDG uptake,suggesting its potential as a promising radiotracer for such malignancies.

OBJECTIVE To explore the intervention mechanism of Shangke Lengtongtie on cold hyperalgesia in KOA mice based on the HMGB1/CXCL12/CXCR4 signaling axis.METHODS Monosodium iodoacetate(MIA)was used for the intra-articular injec-tion into the knee joint to establish mice model of knee osteoarthritis(KOA).Peripheral blood monocytes were extracted from mice,cultured,and then reinfused into the tail vein of the mice.Subsequently,in vivo animal imaging was used to observe the recruitment sites of these monocytes.The cold hyperalgesia threshold was measured at various time points in each group of mice.Hematoxylin and eosin(HE)staining was used to evaluate the level of synovial pathological changes.ELISA was employed to detect the expression of in-flammatory factors IL-1β,TNF-α,and pain mediators CGRP and Substance P in mouse serum.Western blot and qPCR methods were used to detect the protein and gene expression of cold hyperalgesia-related indicators such as TRPA1,TRPM8,HMGB1,CXCL12,CXCR4,Collagen Ⅰ,and Netrin-1 in synovial tissue,as well as DCC in dorsal root ganglia(DRG)tissue.RESULTS In vivo ima-ging showed that after the monocytes were reinfused into KOA mice,they were recruited to the knee joint area,with the HMGB1 group exhibiting a greater recruitment of circulating monocytes at the knee joint.Additionally,compared to the control group,the KOA group and HMGB1 group showed inflammatory pathological changes in the synovium,increased expression of serum inflammatory factors and pain mediators,reduced cold hyperalgesia threshold,and upregulated protein and gene expression of cold hyperalgesia-related indica-tors in synovial and DRG tissues.The changes were more significant in the HMGB1 group compared to the KOA group(P<0.05).Af-ter treatment with Shangke Lengtongtie or GL intervention,synovial inflammation was alleviated,serum inflammatory factors and pain mediators decreased,cold hyperalgesia threshold increased,and the upregulation of cold hyperalgesia-related indicator protein and gene expression levels was significantly reversed(P<0.05).CONCLUSION Shangke Lengtongtie exerts a beneficial effect on the mitigation of synovitis and cold hyperalgesia in KOA mice,a therapeutic mechanism that possibly mediated through the inhibition of the HMGB1/CXCL12/CXCR4 signaling axis.

This article reports a case of membranous nephropathy in an adolescent accompanied by monoclonal IgG1-κ deposition. The 16-year-old female patient was hospitalized for experiencing proteinuria and hematuria for more than 20 days. The patient had a history of mycoplasma infection and acute kidney injury, and renal pathology revealed glomerular membrane lesions accompanied by crescent formation. Electron microscopy showed electron dense deposits in the subepithelial and mesangial regions, and immunofluorescence demonstrated monotypic IgG1-κ deposits in the glomerulus. Bone marrow examination did not find any abnormal plasma cells, nor were there significant abnormalities in serum or urine free light chain κ/λ ratio. The diagnosis was proliferative glomerulonephritis characterized by membranous lesions with monoclonal IgG1-κ deposits. This disease is rare in children and adolescents, and currently there is limited understanding of its mechanism, with limited clinical treatment experience. This article aims to provide clinical insights through case analysis and literature review.

Purpose To investigate the clinical and pathological characteristics of synchronous multiple primary malignancy(sMPM)with lymphoid hematopoietic tissue tumors.Methods A retrospective analysis was conducted on the clinical and pathological data of 20 cases of sMPM associated with lymphoma.Immunohistochemistry using the En-Vision two-step method was performed to detect the expression of relevant proteins,while FISH and next-generation se-quencing technologies were used to identify gene mutations.Relevant literature was also reviewed.Results There were 14 females and 6 males,aged from 30 to 75 years(median 67 years).All of them manifested as solid organ mas-ses complicated by lymphadenopathy.Lymphohematopoietic tissue tumors consisted of:7 cases of Hodgkin lymphoma(6 cases of classic Hodgkin lymphoma,1 case of nodular lymphocyte predominant Hodgkin lymphoma),13 cases of non-Hodgkin lymphoma(4 cases of Follicular lymphoma,2 cases of small lymphocytic lymphoma/chronic lymphocytic leukemia,2 cases of diffuse large B-cell lymphoma,1 case of plasmablastic plasmacytoma,1 case of marginal zone B-cell lymphoma,1 case of B-lymphoblastic lymphoma,2 cases of peripheral T-cell lymphoma,NOS).Solid tumors con-sisted of:9 cases of papillary thyroid carcinoma,1 case of medullary thyroid carcinoma,2 cases of adenocarcinoma of the lung,2 cases of gallbladder adenocarcinoma,2 cases of invasive carcinoma of the breast,2 cases of gastrointestinal adenocarcinoma,1 case of pleomorphic undifferentiated sarcoma of the lower extremity,and 1 case of oropharyngeal squamous cell carcinoma.17 patients underwent surgical resection,and 3 patients were diagnosed by core needle biop-sy or excision biopsy.10 cases of lymphoma involved in the lymph nodes of the tumor drainage area,and 10 cases were found to have lymph node involvement in other areas by imaging examination.Among the 5 cases analyzed by targeted next generation sequencing,no revelent genetic changes were founded,and no germline mutations or chromosomal kar-yotype abnormalities were founded.Based on the tumor types,patients received varying degrees of radiotherapy,chem-otherapy,or follow-up.Follow-up information was available in all cases and ranged from 5 to 96 months,15 were sur-vived and four patients died of the tumor,and 1 case was lost to follow-up.Conclusion MPMs with lymphoid hemato-poietic tissue tumors are rare,clinicians and pathologists should be careful to avoid missing the diagnosis of lymphoma.

Objective:To observe the role of impulsivity in cognitive impairment in manic episodes of bipolar Ⅰ disorder(BPDTI)patients.Methods:180 cases of patients with BPDTI manic episodes admitted to our hospital from February 2024 to December 2024 were selected as the manic group,and another 180 cases of volunteers who were psychologically tested as normal during the same period were selected as the healthy group.The impulse Barratt-11 scale(BIS-11)and the MATRICS Consensus Cognitive Test(MCCB)were used to investigate and evaluate impulsivity and cognitive function,and correlation analysis and risk factor analysis were conducted.Results:In the BIS-11 scale,there was no statistically significant difference between the two groups in the unplanned factor(P＞0.05),but there were significant differences compared between the two groups in cognitive,motor factors,and total score(P＜0.05).The MCCB scores of the manic group in information processing speed,working memory,word learning,visual learning,social cognition,reasoning and problem solving,and attention vigilance were significantly lower than those of the healthy group(P＜0.05).The relationship between BIS-11 total score and cognitive impulsivity factor and MCCB total score and word learning showed there were negative correlation(P＜0.05);The exercise factor in the BIS-11 scale were negatively correlated with the MCCB total score and working memory factor(P＜0.05);The unplanned factor in the BIS-11 scale showed there were negative correlation with the MCCB total score,word learning(P＜0.05),and information processing speed.BIS-11,the number of years of education was an influencing factor for BPDTI mania(P＜0.05).Conclusion:BPDTI mania patients had high impulsivity and cognitive impairment,high impulsivity and number of years of education were influencing factors for mania,high impulsivity affected cognitive function through corresponding brain regions,aggravating the condition.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Lingguizhugan Decoction (LGZG) demonstrates significant efficacy in treating various cardiovascular diseases clinically, yet its precise mechanism of action remains elusive. This study aimed to elucidate the potential mechanisms and effects of LGZG on isoproterenol (ISO) continuous stimulation-induced chronic heart failure (CHF) in mice, providing direct experimental evidence for further clinical applications. In vivo, continuous ISO infusion was administered to mice, and ventricular myocytes were utilized to explore LGZG?s potential mechanism of action on the ?1-adrenergic receptor (?1-AR)/Gs/G protein-coupled receptor kinases (GRKs)/?-arrestin signaling deflection system in the heart. The findings reveal that LGZG significantly reduced the messenger ribonucleic acid (mRNA) expression of hypertrophy-related biomarkers [atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP)] and improved cardiac remodeling and left ventricular diastolic function in mice with ISO-induced CHF. Furthermore, LGZG inhibited the overactivation of Gs/cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling and downregulated the downstream transcriptional activity of cAMP-response element binding protein (CREB) and the expression of the coactivator CBP/P300. Notably, LGZG downregulated the expression of ?-arrestin1 and GRK 2/3/5 while upregulating the expression of ?1-AR and ?-arrestin2. These results suggest that LGZG inhibits Gs/cAMP/PKA signaling and ?-arrestin/GRK-mediated desensitization and internalization of ?1-AR, potentially exerting cardioprotective effects through the synergistic regulation of the ?1-AR/Gs/GRKs/?-arrestin signaling deflection system via multiple pathways.
