Owing to physical and mental immaturity， children require special protection in medical research. With the rise of real-world research， ethical issues such as informed consent， privacy protection， and risk-benefit assessment have become particularly prominent in pediatric studies due to diverse data sources and complex study designs. Although institutional review boards constitute the primary safeguard for research ethics， journal editors play an irreplaceable role in pre-publication ethical gatekeeping. From the perspective of journal editors， this paper reviewed common ethical risks in pediatric real-world research， including the lack of scientific value in research topics， unjust control groups， inadequate privacy protection， and other issues. Based on the four principles of biomedical ethics and the three-tier review process， this study constructed a structured ethical review framework. The framework comprised three levels： basic compliance screening at the initial review， substantive risk assessment and grading at the secondary review， and escalated handling of high‑risk manuscripts at the final review， and it achieved a transformation from formal compliance verification to substantive ethical assessment led by risk grading. This could provide effective ethical risk assessment tools for journal editors and offer references for medical journals to improve pre-publication ethical governance.

ObjectiveTo investigate the effect and mechanism of Shuangshen Ningxin capsules （SSNX） in regulating the nuclear factor-κB （NF-κB） and mitogen-activated protein kinase （MAPK） pathways to inhibit inflammation and alleviate myocardial ischemia-reperfusion injury （MIRI） in rats. MethodsThe 45 healthy male Sprague-Dawley （SD） rats were divided into sham operation group， model group， and SSNX capsules group （90 mg·kg^-1）. The left anterior descending coronary artery was ligated to establish the MIRI model. Cardiac function was evaluated by echocardiography， and microvascular reperfusion was analyzed using contrast echocardiography. Myocardial inflammation and injury were assessed by hematoxylin and eosin （HE） staining， immunohistochemistry， and TdT-mediated dUTP nick end labeling （TUNEL）. The expression levels of cardiac inflammatory cytokines， including interleukin-1α （IL-1α）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） were detected by enzyme-linked immunosorbent assay （ELISA）. Core differentially expressed genes （DEGs） and enriched pathways were screened by transcriptome sequencing. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to verify the mRNA expression of Toll-like receptor 2 （TLR2）， chemokine （C-X-C motif） ligand 1 （CXCL1） and prostaglandin-endoperoxide synthase 2 （PTGS2）， as well as the protein expression of Caspase-3， cleaved Caspase-3， p-NF-κB/NF-κB， phosphorylated extracellular signal-regulated kinase 1/2 （p-ERK1/2/ERK1/2） and p-p38 MAPK/p38 MAPK. ResultsCompared with the sham operation group， the ejection fraction （EF）， fractional shortening （FS）， stroke volume （SV） and cardiac output （CO） of the model group were significantly decreased （P<0.01）， the peak time of myocardial perfusion was prolonged （P<0.01）， hypoxia-inducible factor （HIF）-1α and α-smooth muscle actin （SMA） expression increased （P<0.01）， the concentrations of inflammatory factors IL-1α， IL-6， TNF-α， TLR2， CXCL1 and PTGS2 increased （P<0.01）， and the expression of cleaved Caspase-3， p-NF-κB/NF-κB， p-ERK1/2/ERK1/2 and p-p38 MAPK/p38 MAPK proteins was significantly increased （P<0.01）. SSNX could improve cardiac function （P<0.05， P<0.01）， and significantly shorten the peak time of myocardial perfusion （P<0.01）. Moreover， it could also down-regulate HIF-1α and a-SMA expression （P<0.05， P<0.01）， and reduce the concentrations of IL-1α， IL-6， TNF-α （P<0.01）， and the mRNA expression of TLR2， CXCL1 and PTGS2 （P<0.01）. Additionally， SSNX inhibited the apoptosis rate （P<0.01） and significantly reduced the expression of Cleaved Caspase-3， p-NF-κB/NF-κB， p-ERK1/2/ERK1/2 and p-p38 MAPK/p38 MAPK proteins （P<0.01）. ConclusionSSNX can alleviate cardiac inflammation by regulating the NF-κB and MAPK signaling pathways， thereby effectively preventing and alleviating myocardial reperfusion injury.

Obesity and overweight remain major global public health challenges.In this paper,we examine current applications of digital nutrition technologies in weight management using the scoping review framework of Arksey and O'Malley.Visual recognition technologies have evolved from early-stage food image recognition into more advanced systems,although the vast diversity of food types continues to pose challenges for accuracy and generalizability.The combination of wearable devices and non-wearable sensors has increased the diversity of collected data and improved user comfort.Data integration and analysis tools,such as digital virtual twins,support personalized interventions by integrating multidimensional data.In addition,emerging applications have demonstrated encouraging clinical outcomes.However,existing studies have limitations,such as small sample sizes,high levels of information bias,and low evidence quality.Barriers,such as limited accessibility and high initial costs,further constrain the scalability of digital nutrition tools.Future studies should focus on expanding sample sizes,improving population diversity,and developing effective assessment methods and adjustments for specific target populations.Privacy and data security concerns must also be addressed to ensure safe implementation.Overall,digital nutrition technologies offer a promising approach to weight management,but continuous efforts in research and cost reduction are needed to fully realize their potential in weight management and to promote health for all.

Hyaluronic acid (HA) possesses excellent biocompatibility, biodegradability, and non-immunogenicity, and exhibits active targeting capability to receptors such as cluster of differentiation 44 (CD44). Therefore, HA has become an important material for the design and preparation of drug delivery carriers in recent years. HA is rich in functional groups that can be chemically modified, but different modification methods and sites can affect its biological properties. This paper summarizes and discusses the effects of chemical modification on the biological properties of HA based on the formation mechanisms of such properties, as well as the derivatization and characterization methods of HA, so as to provide some reference for rational research on chemical modification of HA.

To investigate the effect of Xuebijing injection (XBJ) on cGAS/STING pathway in alleviating sepsis-induced acute lung injury (ALI), the mouse sepsis-induced ALI model was established by cecal ligation and puncture (CLP), and the cell inflammation model was constructed by LPS stimulating RAW264.7 cells. The effects of XBJ on lung tissue injury and cGAS/STING pathway-related protein expression in septic mice were investigated by HE staining, ELISA, and Western blot. The results showed that XBJ intervention could alleviate lung tissue injury, reduce serum IL-6, TNF-α, IFN-β, IL-1-β levels, and the expression of cGAS, STING, p-TBK1, and p-IRF3 proteins in lung tissue in vivo, and reduce the mRNA level of related inflammatory factors in RAW264.7 cells and the expression of cGAS/STING pathway proteins in vitro. The results showed that XBJ could play a role in the prevention and treatment of sepsis-induced ALI by inhibiting the inflammatory response via inhibition of the activation of cGAS/STING pathway. This study provides a new molecular mechanism for the clinical prevention and treatment of sepsis-induced acute lung injury with XBJ.

Purpose To compare the expression and pattern of EBNA2 in infectious mononucleosis(IM),EBV-positive diffuse large B-cell lymphoma(EBV+DLBCL),and EBV+DLBCL arising in immune deficiency/dysregulation(IDD-related EBV+DLBCL),and to investigate the potential diagnostic value of EBNA2 in IM and EBV-associated diffuse large B-cell lymphoma.Methods A retrospective study was conducted on 46 cases of IM,31 cases of EBV+DLBCL,and 16 cases of IDD(post-transplantation)-related EBV+DLBCL.Clinical information,immunohistochemis-try and EBER were reviewed to further confirm the diagnoses.All samples were stained for EBNA2.The expression ra-tio and intensity of EBER and EBNA2 in the same area were assessed.Results EBER was positive in all IM,EBV+DLBCL,and IDD(post-transplantation)-related EBV+DLBCL,while the positivity rate of EBNA2 was 95.65％,6.45％,and 100％,respectively.The positive intensity of EBNA2 was weak(71.73％),strong(87.5％)and nega-tive(93.54％)in IM,IDD(post-transplantation)-related EBV+DLBCL and EBV+DLBCL respectively.The average values of EBNA2/EBER were 31％,3％,and 78％among the three groups.The positivity rate and average value of EBNA2/EBER in IM were significantly higher than those in EBV+DLBCL(P＜0.001);however,the average value of EBNA2/EBER was significantly lower than that in IDD(post-transplantation)-related EBV+DLBCL(P＜0.001).The weak positive expression of EBNA2 in IM was significantly higher than that in EBV+DLBCL(P＜0.001),where-as strong positive expression of EBNA2 in IDD(post-transplantation)-related EBV+DLBCL was higher than that in IM(P＜0.001).Conclusion EBNA2 is often positive in IM and predominantly weakly positive,which is distinct from the pattern in EBV+DLBCL and IDD(post-transplantation)-related EBV+DLBCL.EBNA2 can serve as an effective marker for distinguishing them.
