ObjectiveTo establish a tumor prognostic risk assessment model related to target genes of the miR-34 family. MethodsTarget genes of the miR-34 family were screened， and the scores of miR-34 target genes were assessed in 16 tumor types. Univariate Cox regression analysis was used to identify the tumor type with the strongest correlation between miR-34 target gene scores and overall survival （OS）. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） analyses were performed to elucidate the functional roles and signaling pathways of miR-34 target genes. A prognostic risk model based on the miR-34 target genes was constructed using univariate Cox and LASSO regression analyses. Quantitative real-time PCR （qPCR） and dual-luciferase reporter assays were conducted to validate whether the target genes bind to miR-34 and measure their RNA expression levels in the relevant tumors. Additionally， the risk score was integrated with other clinical indicators to develop a nomogram prediction model for patient survival. ResultsA total of 65 target genes of the miR-34 family were screened. The cancer type exhibiting stronger correlation between the target gene scores and OS was lung adenocarcinoma （P = 0.003， HR= 5.150）. Furthermore， miR-34 target genes were predominantly enriched in oxidative stress pathways and various tumor-related processes. Three genes， LDHA， GALNT7， and SATB2， were identified as core components of the prognostic analysis model for lung adenocarcinoma. Additionally， the constructed nomogram model demonstrated robust predictive performance. ConclusionThe risk model and prognosis model of lung adenocarcinoma constructed based on the key target genes of miR-34 have good predictive performance.

Transfusion and Anemia Expertise Initiative-Control/Avoidance of Bleeding developed a strategy for platelet and plasma infusion management in critically ill children based on systematic reviews and consensus meetings of international multidisciplinary experts. One good practice statement and six expert consensus statements were proposed for plasma and platelet transfusions in critically ill children following severe trauma, traumatic brain injury, and/or intracranial hemorrhage. This article introduces the specific methods and basis for the formation of recommendations in this part of the guide.

ObjectiveTo explore the effectiveness of feedforward control mode on improving occupational burnout among operating room nurses through theoretical research and clinical practice， with a view to promoting their physical and mental health and enhancing the quality of surgical nursing. MethodsA total of 440 operating room nurses from different regions， scales， and nursing experiences in Shaanxi Province from November 2023 to December 2023 were randomly divided into an experimental group and a control group， with 220 nurses in each group. While the control group received routine intervention measures， the experimental group introduced a feedforward control mode based on the control group， with “emotional exhaustion，” “depersonalization，”and“personal achievement” as observation indicators. ResultsThe incidence of occupational burnout in the experimental group was 11.4%， while that in the control group was 20.0%. The experimental group showed a significantly lower incidence than the control group （P=0.013）. ConclusionThe feedforward control mode can significantly alleviate nurses’ sense of job burnout， promote the improvement of surgical nursing quality， as well as continuously improve the scientific rigor， advancement， and humanistic nature of nursing services， which is conducive to building a harmonious and efficient nursing team. The spirit of teamwork， reflected in mutual support， mutual trust， and joint efforts for surgical success and patient health， has become an important component of nurses’ professional ethics.

Objective:To investigate the status quo and influencing factors of humanistic concern among nursing undergraduates, and to explore the educational path of improving humanistic concern.Methods:A total of 345 nursing undergraduates from Xiangya School of Nursing of Central South University were investigated using a questionnaire of general demographic data, the Caring Ability Inventory, and the Self-directed Learning Instrument. The SPSS 26.0 statistical software was used for data analysis. The humanistic caring ability scores of nursing undergraduates with different characteristics were compared by the independent sample t-test and analysis of variance, and the pairwise comparison was conducted by the least significant difference t-test. All dimensions and total scores of humanistic caring ability and self-directed learning ability failed to meet normal distribution, and the correlation between them was determined by Spearman correlation analysis. Results:The humanistic caring ability score of nursing undergraduates was (169.52±10.62). The correlation analysis showed that the humanistic caring ability of nursing undergraduates was positively correlated with their self-directed learning ability ( r=0.426, P<0.001). The stepwise regression analysis showed that interpersonal communication ability, learning motivation, grades, genders, and class leader experience were influencing factors of humanistic caring ability of nursing undergraduates. Conclusions:Nursing undergraduates should improve their humanistic caring ability, whose score is lower than that in the existing research (175.70±18.74). In humanistic education, nursing educators should pay attention to individualized development needs of nursing undergraduates with different grades and genders, set students with class leader experience as a good example, and effectively improve the humanistic caring ability of nursing undergraduates by stimulating learning motivation and strengthening interpersonal communication.

This study characterized the whole-genome sequences of 45 Coxsackievirus A6(CVA6)strains isolated from Pudong District,Shanghai,during 2015-2023,to elucidate regional genetic evolution and recombination patterns.Viral genomes were ampli-fied and sequenced with Illumina MiSeq platforms,and phylogenetic analysis of the VP1 and 3D regions was conducted via MEGA 11(maximum-likelihood method,bootstrap=1 000).Nucleotide/amino acid homology and variation sites were assessed in DNAstar v7.0,and recombination events were identified with SimPlot v3.5.1 and RDP4.All isolates belonged to the D3a subtype,and exhibited intra-strain nucleotide and amino acid homologies of 88.0%-99.9%and 92.4%-100%,respectively,in contrast to lower homologies to the prototype Gdula strain(78.0%-80.5%nucleotide;94.5%-95.1%amino acid).Thirty-six mutation sites were identified in the VP1 re-gion.Recombination analysis revealed frequent cross-serotype events involving CVA4 and EV-A71,with dominant RF-A(84.5%)and minor RF-K(15.5%)patterns localized in the 3D region.This study elucidated the gene recombination and genetic evolution of CVA6 in Pudong District,Shanghai,thereby providing data support to enhance understanding of the evolutionary trends and genetic characteristics of coxsackieviruses,and offering theoretical evidence for the prevention and control of CVA6.

With the aging of the global population， osteoporosis （OP） is becoming a major public health concern worldwide. Currently， the commonly used anti-osteoporosis drugs in clinical practice have limited application due to many side effects. Therefore， developing more effective and safer strategies for the prevention and treatment of OP has become a research focus in this field. In recent years， the clinical efficacy and advantages of traditional Chinese medicine （TCM） in treating OP have been gradually recognized. With the deepening pharmacological research on TCM for OP prevention and treatment， it is found that the active ingredients of Scutellaria baicalensis can promote bone formation or inhibit bone resorption by regulating signaling pathways， including Wnt/β-catenin， osteoprotegerin （OB）/receptor activator of nuclear factor-κB ligand （RANKL）/RANK （OPG/RANKL/RANK）， and bone morphogenetic protein 2 （BMP-2）/Smad， mitogen-activated protein kinase （MAPK）， and mammalian target of rapamycin （mTOR）. However， existing research on active ingredients of S. baicalensis for OP treatment is scattered， making it difficult for scholars to gain a systematic understanding of its research and application. This review summarized the literature on the active ingredients of S. baicalensis in OP treatment worldwide， clarified their mechanisms of action， and explored some issues， providing references for the integration of TCM in OP prevention and treatment.
