Hypothermia is a clinical syndrome characterized by core body temperature<35℃,caused by significant heat loss from body surface in cold environment.As a systemic cold injury,it can be lethal if treatment is delayed.Emergent diagnosis and treatment of hypothermia are expected to improve the prognosis of patients.In 2005,the U.S.Army Research Institute of Environmental Medicine(USARIEM)issued guidelines for the prevention and management of cold injuries,but there has been no corresponding standard in China.Therefore,Emergency Branch of Chinese Medical Rescue Association,Emergency Medical Equipment Society of China Association of Medical Equipment,Integrated Rehabilitation Medical Branch of Chinese Medical Rescue Association,and Pre-Hospital Emergency Care Working Committee of Chinese Aging Well Association jointly developed the Chinese Expert Consensus on Emergent Treatment of Hypothermia(2025 edition).The consensus covers the pathophysiology,etiology and epidemiology,diagnosis and severity grading,prehospital treatment,and in-hospital treatment of hypothermia,including 15 recommendations in total,aiming to provide guidance for the relevant clinical rescue work.

Objective To develop a decision support system for clinical nursing plans based on nursing diagno-sis and explore its application effects,in order to provide references for optimizing the clinical nursing process and improving the quality of nursing.Methods A multidisciplinary research team was established to construct a clini-cal nursing plan decision support system framework from 3 aspects,namely nursing diagnosis,nursing interventions,and outcome tracking.The system built a clinical nursing diagnosis decision knowledge base through 3 dimensions,namely basic nursing diagnoses,specialty disease nursing diagnoses,and nursing-related technical diagnoses.Deep learning-based artificial intelligence capture technology was developed to achieve intelligent matching and generate clinical nursing plan forms.Implemented in a tertiary hospital in Yichang City,Hubei Province,a control group(June to August 2024)and an experimental group(October to December 2024)were compared regarding nursing diagnosis implementation rate,nursing plan documentation accuracy,and clinical nursing quality scores.Results This research showed a significant improvements for nursing diagnosis implementation rate increased from 94.88％to 97.25％,and nursing plan documentation accuracy improved from 90.38％to 95.33％.Compared with the control group,the experimental group demonstrated statistically significant enhancements in deep vein thrombosis preven-tion,fall prevention,pressure injury management,unplanned extubation control,bloodstream infection control,catheter-related infection prevention,and key specialty nursing quality indicators(all P＜0.05).Conclusion The nursing di-agnosis-based clinical decision support system effectively improves nurses'diagnostic implementation rates,enhances documentation accuracy of nursing plans,and elevates overall clinical nursing quality.

Objective To analyze the research status,hotspots,and trends of wearable devices in nursing applications both domestically and internationally.Methods Using China National Knowledge Infrastructure,Wanfang Data Knowledge Service Platform,and Embase core databases as data sources,VOSviewer was used to visualize and analyze the publication time,keywords,and other relevant literature.Results Total of 428 articles were included,including 196 Chinese articles and 232 English articles.The overall publication volume showed an upward trend.Domestic research focuses on chronic diseases,artificial intelligence,and nursing,with the main research subjects being the elderly;Foreign research focuses on smart devices,self-monitoring,and quality of life,with the main research subjects being adults.Conclusion Currently,the number of publications on the application of wearable devices in nursing is relatively small,but the overall research heat is on the rise,mainly used for chronic diseases and self-monitoring.In the future,the application scope of wearable devices should be expanded and their potential value should be explored to promote the innovation and progress of nursing models.

AIM To investigate the clinical effects of Yifei Tongluo Decoction combined with azithromycin on patients with childern severe Mycoplasma pneumoniae pneumonia due to Toxic Heat Blocking Lung.METHODS One hundred and fifty-six patients were randomly assigned into control group(78 cases)for 7-day administration of azithromycin,and observation group(78 cases)for 7-day administration of both Yifei Tongluo Decoction and azithromycin.The changes in clinical effects,disappearance time of local symptoms,mycoplasmas,pulmonary imaging score,Toxic Heat Blocking Lung score,pulmonary function indices(PEF,VPTEF,MMF,TPTEF),inflammatory factors(sB7-H3,Cgp-39,sICAM-1,CCL5),immune function indices(RBC-C3bR,RBC-ICR,CD3+,CD4+)and safety indices were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05),along with shorter disappearance time of local symptoms(P＜0.05).After the treatment,the two groups displayed decreased mycoplasmas,pulmonary imaging score,Toxic Heat Blocking Lung score,inflammatory factors,RBC-ICR(P＜0.05),and increased pulmonary function indices,RBC-C3bR,CD3+,CD4+(P＜0.05),especially for the observation group(P＜0.05).No obvious difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with childern severe Mycoplasma pneumoniae pneumonia due to Toxic Heat Blocking Lung,Yifei Tongluo Decoction combined with azithromycin can safely and effectively alleviate clinical symptoms,improve pulmonary functions,and reduce body inflammatory responses.

Aim To explore the possible regulatory effect of leptin on acyl-CoA synthetase long chain fami-ly member ACSL5 and their effect on migration and in-vasion of breast cancer cell,and to explore the underly-ing mechanism.Methods The expression of leptin receptor was detected by immunofluorescence assay.The migration and invasion ability of MCF-7 cells were detected by wound healing assay and Transwell assay respectively.The downstream target gene of leptin was analyzed by PCR microarray data.The expression of ACSL5 in breast cancer and its correlation with the staging and prognosis of breast cancer patients were as-sessed uing bioinformatics methods.The expression of ACSL5 in MCF-7 cells treated with different concentra-tions of leptin was detected using real time fluorescence quantitative polymerase chain reaction(RT-qPCR).Overexpressing ACSL5 was constructed by lentiviral transfection;the expressions of EMT related proteins,AMPK-α and p-AMPK-α were detected by Western blot.Results Leptin promoted breast cancer cell mi-gration and invasion and EMT.ACSL5 was significant-ly low expressed in breast cancer and related to progno-sis.Leptin downregulated the expression of ACSL5 through OBR.Leptin activated AMPK pathway to downregulate ACSL5 and promote migration,invasion and EMT of breast cancer cells.Conclusions Leptin may promote the migration,invasion and EMT of breast cancer by downregulating ACSL5 through activating AMPK pathway.

OBJECTIVE To analyze the clinical characteristics and pathogens for mixed infections in children with pertussis,so as to references for clinical diagnosis and treatment.METHODS A retrospective analysis was conduc-ted on the clinical data of 350 children diagnosed with pertussis and hospitalized in Wuhan Children's Hospital from Jan.2022 to Dec.2023.The clinical characteristics,peak white blood cell count,peak lymphocyte ratio,high-sensitivity C-reactive protein or C-reactive protein,procalcitonin and complications were compared between different age groups,as well as between the single infection group and the mixed infection group.RESULTS Mixed infections were observed in 291 children(83.14％),predominantly viral(63.43％,222/350),with human rhinovirus/enterovirus being the most common(32.57％,114/350).For children aged＜6 months,6 months to＜1 year and 1 to＜3 years,the incidence of family contact history of cough,panting,hasty breathing,respira-tory failure,peak white blood cell count and peak lymphocyte ratio were all higher than those aged 3 to＜6 years and≥6years(all P＜0.05).The incidence of post-cough vomiting was higher in children aged 6 months to＜1 year and 1 to＜3 years compared to other age groups(P＜0.05).The length of hospital stay decreased with in-creasing age(P＜0.05).The proportions of children with paroxysmal spasmodic cough,post-cough cyanosis,post-cough flushing,coughing spells,inspiratory three concave sign,pneumonia and pulmonary phlegm rales all generally decreased with age(all P＜0.05).Nodding respiration was only observed in children aged＜1 year(P＜0.05).The incidence of fever,co-infection with bacteria and Mycoplasma pneumoniae infection was higher in children aged 6 months to＜1 year,1 to＜3 years,3 to＜6 years and ≥ 6 years compared to those aged＜6 months(all P＜0.05).The incidence of fever was higher in the mixed infection group than that in the single in-fection group(P＜0.05).Children in the single infection group had longer hospital stays,higher incidence of par-oxysmal spasmodic cough,nocturnal cough,post-cough flushing,coughing spells,pulmonary phlegm rales and higher peak lymphocyte ratio(all P＜0.05).The incidence of paroxysmal spasmodic cough was higher in the sin-gle infection group for children aged＜3 months(P＜0.05).CONCLUSIONS The younger children with pertussis have a higher proportion of family contact history of cough and are more prone to clinical manifestations such as paroxysmal spasmodic cough,post-cough vomiting,post-cough cyanosis,and pneumonia.They also have higher peak white blood cell counts,peak lymphocyte ratios and longer hospital stays.As children'age increased,the in-cidence of fever,bacterial,and mycoplasma infections also increased.The types of pathogens in mixed infections varies with patients' age and pertussis mixed infections may mask typical clinical symptoms.

Objective To investigate the possible association between cross-domain associative memory(AM)impairment and hippocampal subfield volumes in patients with schizophrenia(SCZ).Methods We enrolled 28 SCZ patients from Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,and 28 healthy controls(HCs)between 2019 and 2021.Based on an innovative AM paradigm and automated segmentation,3D-T1 weighted data of the objects were processed with PhiPipe and FreeSurfer.Differences in subfield volums between the two groups were analyzed using ANCOVA,while their relationship with AM scores was assessed using Pearson correlation.Results SCZ patients exhibited significantly poorer AM performance across three conditions compared with HCs.Marginally significant reductions were observed in the total volume of bilateral hippocampus,encompassing both the hippocampal head and body.Significant volume reductions were identified in the bilateral presubiculum and parasubiculum.The volumes of bilateral presubiculum head(r=0.273,P=0.042),parasubiculum(r=0.397,P=0.002),and CA1 head(r=0.382,P=0.004)exhibited positive correlations with cross-domain AM performance.Conclusion The bilateral presubiculum and parasubiculum,as hippocampal subregions significantly associated with cross-modal AM deficits in SCZ,may play a crucial role in the pathology of AM.

In recent decades,the incidence of human papillomavirus(HPV)-associated oropharyngeal squamous cell carcinoma(OPSCC)has shown a marked increase.Significant changes have also occurred in the OPSCC diagnosis and treatment paradigm.Deter-mining HPV status prior to treatment is now essential,and radiotherapy/chemotherapy,immunotherapy,and minimally invasive surgical techniques have progressively emerged as key modalities for managing OPSCC.However,alongside these paradigm shifts,a comprehen-sive technical consensus guiding the entire diagnostic and therapeutic process for OPSCC patients is currently lacking.Given China's large population base and the rising incidence of OPSCC,an expert panel convened to develop a clinical technical consensus on OPSCC diagno-sis and management tailored to China's specific context.This consensus aims to further enhance and standardize understanding of OPSCC management techniques among relevant healthcare professionals.

Triple-negative breast cancer(TNBC)is a highly aggressive and prognostically unfavorable subtype.Tertiary lymphoid structure(TLS)within the tumor microenvironment,comprising dendritic cells,B cells,T cells,and other immune cells,modulate the tumor immune response.The heterogeneity of TLS in TNBC,such as density,structural maturity,and molecular expression patterns,affects the tumor immune microenvironment and,consequently,treatment responses and clinical outcomes.Studies indicate a positive correlation between the density and maturity of TLS and the pathological complete response(pCR)of TNBC patients,with TLS enhancing the quantity of tumor-infiltrating immune cells and improving anti-tumor immune responses,thereby increasing sensitivity to chemotherapy and immunotherapy.Recent research has found that mature TLS are associated with effective immune responses,becoming significant predictors of treatment response.The combination of TLS with immune checkpoint inhibitors has shown promising prospects.Research demonstrates that promoting the formation or enhancing the functionality of TLS can improve anti-tumor immune effects and enhance treatment outcomes for TNBC patients.Targeting TLS may reduce immune evasion and increase the sensitivity to immunotherapy.However,clinical application of TLS still faces challenges,particularly the impact of their heterogeneity on treatment response.Current assessment methods for TLS are not standardized,lacking a uniform standard and diagnostic system,which limits their widespread application.Future research should focus on resolving these issues by developing standardized assessment tools and further exploring the role of TLS in immune escape and resistance mechanisms.This review aimed to summarize and analyze the existing research progress on TLS in TNBC,in order to provide new ideas for the development of personalized immunotherapy strategies.
