Cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic disorders are the 3 major chronic diseases threatening human health, which are closely related and often coexist, significantly increasing the difficulty of disease management. In response, the American Heart Association (AHA) proposed a novel disease concept of “cardiovascular-kidney-metabolic (CKM) syndrome” in October 2023, which has triggered widespread concern about the co-treatment of heart and kidney diseases and the prevention and treatment of metabolic disorders around the world. This review posits that effectively managing CKM syndrome requires a new and multidimensional paradigm for diagnosis and risk prediction that integrates biological insights, advanced technology and social determinants of health (SDoH). We argue that the core pathological driver is a “metabolic toxic environment”, fueled by adipose tissue dysfunction and characterized by a vicious cycle of systemic inflammation and oxidative stress, which forms a common pathway to multi-organ injury. The at-risk population is defined not only by biological characteristics but also significantly impacted by adverse SDoH, which can elevate the risk of advanced CKM by a factor of 1.18 to 3.50, underscoring the critical need for equity in screening and care strategies. This review systematically charts the progression of diagnostic technologies. In diagnostics, we highlight a crucial shift from single-marker assessments to comprehensive multi-marker panels. The synergistic application of traditional biomarkers like NT-proBNP (reflecting cardiac stress) and UACR (indicating kidney damage) with emerging indicators such as systemic immune-inflammation index (SII) and Klotho protein facilitates a holistic evaluation of multi-organ health. Furthermore, this paper explores the pivotal role of non-invasive monitoring technologies in detecting subclinical disease. Techniques like multi-wavelength photoplethysmography (PPG) and impedance cardiography (ICG) provide a real-time window into microcirculatory and hemodynamic status, enabling the identification of early, often asymptomatic, functional abnormalities that precede overt organ failure. In imaging, progress is marked by a move towards precise, quantitative evaluation, exemplified by artificial intelligence-powered quantitative computed tomography (AI-QCT). By integrating AI-QCT with clinical risk factors, the predictive accuracy for cardiovascular events within 6 months significantly improves, with the area under the curve (AUC) increasing from 0.637 to 0.688, demonstrating its potential for reclassifying risk in CKM stage 3. In the domain of risk prediction, we trace the evolution from traditional statistical tools to next-generation models. The new PREVENT equation represents a major advancement by incorporating key kidney function markers (eGFR, UACR), which can enhance the detection rate of CKD in primary care by 20%-30%. However, we contend that the future lies in dynamic, machine learning-based models. Algorithms such as XGBoost have achieved an AUC of 0.82 for predicting 365-day cardiovascular events, while deep learning models like KFDeep have demonstrated exceptional performance in predicting kidney failure risk with an AUC of 0.946. Unlike static calculators, these AI-driven tools can process complex, multimodal data and continuously update risk profiles, paving the way for truly personalized and proactive medicine. In conclusion, this review advocates for a paradigm shift toward a holistic and technologically advanced framework for CKM management. Future efforts must focus on the deep integration of multimodal data, the development of novel AI-driven biomarkers, the implementation of refined SDoH-informed interventions, and the promotion of interdisciplinary collaboration to construct an efficient, equitable, and effective system for CKM screening and intervention.

ObjectiveTo conduct comprehensive assessment of internal and external cadmium exposure and health risks for Shanghai residents. MethodsCadmium levels in food samples were calculated by employing two dietary exposure assessment methods， total diet study （TDS） and food frequency questionnaire （FFQ）， to estimate the daily dietary cadmium exposure of Shanghai residents. The provisional tolerable monthly intake （PTMI） of cadmium set by joint food and agriculture organization/WHO expert committee on food additives （JECFA） was applied to evaluate the health risk. Differences in dietary and urinary cadmium were compared by rank-sum test among different regions， age， gender， smoking status， and BMI groups， and the association between internal and external cadmium exposure was investigated by correlation analysis. ResultsThe mean value of urinary cadmium for 1 300 respondents was 0.542 μg·L^-1. Urinary cadmium was higher in the population in central urban and urban-rural fringe areas than in the suburban area， higher in the older age group than in the younger age group， and higher in the smoking group than in the non-smoking group （all P<0.01）. The two assessment methods showed that the mean values of daily dietary cadmium exposure for Shanghai residents were 0.306 and 0.090 μg·kg^-1， with 3.69% and 0.85% of Shanghai residents exceeding the PTMI， respectively. Correlation analyses showed that dietary exposure to cadmium based on the FFQ method was positively correlated with the urinary cadmium level when smoking status， age， gender， and BMI were adjusted. ConclusionDietary exposure to cadmium of Shanghai residents is mainly derived from vegetables， aquatic products， cereals and potatoes， and is overall at a low-risk level. Dietary exposure assessment based on FFQ and risk monitoring data can effectively estimate long-term cadmium exposure.

Objective To observe the effect of multi-modal hand hygiene(HH)intervention on HH compliance,as well as the relationship between HH compliance and the healthcare-associated(HA)case infection incidence.Methods From 2014 to 2022,the infection control team in a tertiary first-class hospital implemented multi-modal HH intervention for health care workers(HCWs).The changing trend of HH monitoring data,the correlation be-tween HH compliance rate and HA case infection incidence were analyzed retrospectively.Results The consump-tion of HH products in the wards showed a stable upward trend;HH compliance rate increased from 64.98％in 2014 to 85.01％in 2022(P＜0.001),and HA case infection incidence decreased from 1.21％to 0.83％(P＜0.05).HH compliance rate was negatively correlated with HA case infection incidence(r=-0.369,P=0.027).HH compliance rates in different regions and job posts in each quarter were increased(P＜0.001).For 5 different HH moments in each quarter,HH compliance rate fluctuated slightly before sterile manipulation and after touching patient;presented rising trend after touching surroundings around patient,and decreased before touching patient and after touching patient's body fluid since 2020(P＜0.001).Conclusion Multi-modal HH intervention can im-prove the HH compliance of HCWs,improving their HH awareness is conducive to reducing HA case infection incidence.

Objective:To investigate the epidemiological characteristics, genotypes and genetic evolution of respiratory syncytial virus (RSV) isolated in Shanghai from April 2020 to December 2021, which was a period from the COVID-19 outbreak to the phase of regular epidemic prevention and control.Methods:This retrospective study collected the nasopharyngeal secretions or nasopharyngeal aspirates of children with acute respiratory tract infection (ARTI) admitted to the Shanghai Children′s Hospital from April 2020 to December 2021. PCR-capillary electrophoresis and RT-PCR were used for virus identification and the amplification of the gene fragment of the second hypervariable region of RSV G protein. Homology analysis and phylogenetic analysis were conducted using bioinformatics software. Chi-square test was used to compare the detection rates of RSV. Results:A total of 6 211 samples were collected and 13.62% (846/6 211) of them were positive for RSV. The positive rates of RSV in male and female patients were 14.07% (503/3 574) and 13.01% (343/2 637), respectively, with no significant gender difference (χ 2=1.467, P=0.226). The highest detection rate of RSV was found in children ≤6 months of age, and the rate of RSV infection decreased gradually with age (χ 2=352.942, P<0.001). No RSV-positive specimens were detected from April 2020 to August 2020, after which the detection rate of RSV gradually increased with two epidemic peaks occurring from December 2020 to February 2021 and from August to October 2021. The predominant epidemic subtype was RSV subtype B in 2020 and the first 9 months of 2021, which was gradually replaced by RSV subtype A in the last 3 months of 2021. The 176 strains of RSV subtype A obtained in this study were all ON1 genotype, and the nucleotide homology of the Shanghai epidemic strains was 90.20%-99.50%. All of the 250 strains of RSV subtype B were BA9 genotype, and the nucleotide homology of the Shanghai epidemic strains was 90.10%-100.00%. Conclusions:From April 2020 to December 2021, with the regular prevention and control of COVID-19, there is a change in the epidemic season of RSV. The prevalent genotypes of RSV subtypes A and B are ON1 and BA9, respectively, and the subtype A gradually replaces subtype B as the most prevalent subtype.

Objective·To explore the effect of double homeobox(DUX)protein on the differentiation potential of mouse embryonic stem cells(mESCs)into extraembryonic endoderm(XEN)and the possible mechanism of its action.Methods·Overexpression of DUX cell lines in mESCs was achieved by using a lentiviral system.The proportion of 2-cell-like cells(2CLCs)before and after DUX overexpression was detected by flow cytometry,and the expression of 2-cell stage-specific genes,Dux,zinc finger and SCAN domain containing 4c(Zscan4c),zinc finger protein 352(Zfp352)and murine endogenous retrovirus-L polymerase(MERVL-pol),were detected by real-time quantitative reverse transcription polymerase chain reaction(RT-qPCR).RT-qPCR assay was used to detect the expression of pluripotency factors,nanog homeobox(Nanog),kruppel-like transcription factor 4(Klf4),sex determining region Y-box 2(Sox2),and octamer-binding transcription factor 4(Oct4),in pluripotent state,as well as the expression of signature genes for different germ layers in the differentiated state[endodermal:GATA binding protein 4(Gata4),GATA binding protein 6(Gata6),and sex determining region Y-box 17(Sox17);ectodermal:Nestin and tubulin beta 3 class Ⅲ(Tubb3);mesodermal:heart and neural crest derivatives expressed 1(Hand1),myogenic differentiation 1(Myod1),and kinase insert domain protein receptor(Flk1)].Public RNA sequencing(RNA-seq)data were mined to further clarify the effect of DUX on the differentiation of mESCs into extraembryonic endoderm.Functional and pathway enrichment analyses of differentially expressed genes were performed using Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG),and gene set enrichment analysis(GSEA)to identify the signaling pathways regulated by DUX.Additionally,an in-depth analysis of existing chromatin immunoprecipitation sequencing(ChIP-seq)data was conducted to explore the potential target genes of DUX.Results·Molecular biology experiments showed that overexpression of DUX could effectively maintain the pluripotency of mESCs,which was consistent with the analysis of public RNA-seq data.Differential gene analysis revealed that endodermal genes were specifically upregulated.After differentiation assay of mESCs,RT-qPCR assay experiments showed that mRNA expression of the XEN marker genes(Gata4,Gata6,Sox17)was significantly upregulated(P<0.001).In contrast,there was no specific change in mesodermal and ectodermal genes.GSEA enrichment analysis indicated that DUX might activate the retinoid metabolism signaling pathway,and the analysis of the ChIP-seq data further revealed the presence of a large number of known retinoic acid receptor motif in DUX-bound peaks,which could activate downstream target genes related to the development of the XEN.Conclusion·DUX has a strong correlation with the retinoic acid signaling pathway and it is predicted to activate the retinoic acid signaling pathway,which could promote the tendency of mESCs toward XEN differentiation.

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.

To understand the pathogenicity,virulence genes,drug resistance genes,and drug resistance of Staphylococcus aureus isolated from yaks in some areas of Lhasa and Nagqu City,55 yak nasal swab samples were analyzed for S.aureus in this study.The cocci were isolated and identified,and the carriage of virulence genes and drug resistance genes,as well as the pathogenicity and drug sensitivity of the isolated S.aureus strains,were detected with PCR,artificially infected mice,and the K-B drug susceptibility disk method.Seven strains of S.aureus were isolated from the 55 yak nasal swab samples,with an iso-lation rate of 12.73％.The isolated strains were all pathogenic to mice,with a fatality rate exceeding 60％.These seven strains of S.aureus carried three drug resistance genes(tetM,tet,and mecA)and six virulence genes(seb,sec,clfA,hla,hlb,and nuc).The detection rate of the three drug resistance genes was 100％,whereas the detection rate of the six virulence genes in the isolates ranged from 83.33％to 100％.The resistance rates of the isolated strains to penicillin,ampicillin,and cotrimox-azole reached 85.71％-100％,whereas the resistance rates to tetracycline and ceftazidime were both 28.57％.Thus,yaks in Lhasa and Nagqu cities were found to be infected by S.aureus strains carrying various drug-resistance genes and virulence genes.These strains were highly pathogenic and showed sensi-tivity to most antibacterial drugs.These findings may serve as a reference for treating S.aureus infection in yaks in the cities of Lhasa and Nagqu.
