With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

OBJECTIVE:
To explore the efficacy of a Thalassemia risk assessment software for the screening of thalassemia mutation carriers and distribution of thalassemia genotypes detected by screening.
METHODS:
A total of 6 040 individuals were evaluated at Leshan Maternal and Child Health Care Hospital between 2022 and 2024 using the commonly used clinical thalassemia risk assessment method and the thalassemia screening software, respectively, and the performance indicators of the two methods were compared and analyzed against the result of thalassemia gene testing. This study was approved by the Ethics Committee of our hospital (Ethics No.: LfyLL[2022]005).
RESULTS:
The high-risk rate by the thalassemia screening software was 11.19%, with a sensitivity of 95.12%, specificity of 93.28%, positive predictive value of 43.20%, negative predictive value of 99.72%, and the area under the ROC curve (AUC) was 0.942. The thalassemia gene detection rate of the high-risk samples screened was 4.83%. The high-risk screening rate of the conventional method was 2.50%, with a sensitivity of 51.22%, specificity of 93.28%, positive predictive value of 80.79%, negative predictive value of 97.40%, and the AUC was 0.754. The thalassemia gene detection rate of the high-risk samples was 2.02%.
CONCLUSION
The software can effectively detect thalassemia carriers and significantly reduce the missed detection compared with conventional method, thereby significantly improve the efficacy of screening.

ObjectiveAutism spectrum disorder (ASD) is a neurodevelopmental condition characterized by difficulties with communication and social interaction, restricted and repetitive behaviors. Previous studies have indicated that individuals with ASD exhibit early and lifelong attention deficits, which are closely related to the core symptoms of ASD. Basic visual attention processes may provide a critical foundation for their social communication and interaction abilities. Therefore, this study explores the behavior of children with ASD in capturing attention to changes in topological properties. MethodsOur study recruited twenty-seven ASD children diagnosed by professional clinicians according to DSM-5 and twenty-eight typically developing (TD) age-matched controls. In an attention capture task, we recorded the saccadic behaviors of children with ASD and TD in response to topological change (TC) and non-topological change (nTC) stimuli. Saccadic reaction time (SRT), visual search time (VS), and first fixation dwell time (FFDT) were used as indicators of attentional bias. Pearson correlation tests between the clinical assessment scales and attentional bias were conducted. ResultsThis study found that TD children had significantly faster SRT (P<0.05) and VS (P<0.05) for the TC stimuli compared to the nTC stimuli, while the children with ASD did not exhibit significant differences in either measure (P>0.05). Additionally, ASD children demonstrated significantly less attention towards the TC targets (measured by FFDT), in comparison to TD children (P<0.05). Furthermore, ASD children exhibited a significant negative linear correlation between their attentional bias (measured by VS) and their scores on the compulsive subscale (P<0.05). ConclusionThe results suggest that children with ASD have difficulty shifting their attention to objects with topological changes during change detection. This atypical attention may affect the child’s cognitive and behavioral development, thereby impacting their social communication and interaction. In sum, our findings indicate that difficulties in attentional capture by TC may be a key feature of ASD.

In this study,we aim to evaluate the immunogenicity of the whole-cell proteins isolated from Mycobacterium marinum(MM).The findings of this research may provide scientific basis for the development of new candidate tuberculosis vaccines.Both MM 95014 and Mycobacteriumtuberculosis(MTB)H37Rv cells were routinely cultured and collected.After inactivation,whole-cell proteins were extracted by low-temperature ultrasonic fragmentation and mixed with DDA/Poly:IC adjuvant.The mixture was administered to BALB/c mice subcutaneously with 50 mg/mouse twice with an interval of 10 days.Blood sample was collected before each immunization,as well as 10 days after the last immunization.Blood samples and spleen tissue extracts were measured for serum antibody potency and cytokine levels by an enzyme-linked immunosorbent assay.An in vitro growth inhibition assay(MGIA)was used to assess the ability of mouse bone marrow-derived macrophages,collected after immunization with MM whole-cell proteins,to inhibit MTB growth.A MTB whole mycobacterium proteome microarray was applied to analyze the interaction between the serum in MM immunization group and MTB proteins.Our results indicated that,compared with the adjuvant group,MM whole-cell proteins induced higher levels of Th1 cytokines(IL-2,IFN-γ,IL-12,TNF-α)in the mice.The IgG and IgM antibody titers induced by MM immunization group reached 1∶608 874 and 1∶304 437,respectively.The MGIA results showed that the MM immunization group was able to significantly inhibit MTB growth in vitro.The MTB proteome microarray results indicated that there were 226 and 324 cross-proteins with IgG and IgM antibodies,respectively.This study suggested that MM whole-cell proteins can induce high levels of cellular and humoral immune responses in mice and exhibit strong inhibition of MTB growth in vitro.The results may suggest potential application value of MM whole-cell proteins as a novel candidate vaccine for tuberculosis.

Chronic heart failure (CHF) represents the terminal stage of cardiovascular diseases, and its prevalence remains high in China. In this study, existing animal models of CHF were retrieved and categorized. In combination with the characteristics of CHF from traditional Chinese medicine (TCM) and Western medicine perspectives, the models were weighted, and their clinical consistency was evaluated. The advantages and disadvantages of the models were assessed. Among them, models with higher TCM clinical consistency included the doxorubicin-induced model, the isoproterenol-induced model, and the left anterior descending coronary artery ligation model, each with a TCM consistency rate of 90%. The animal model established by the left anterior descending coronary artery ligation showed a high degree of clinical consistency with Western medicine, with a consistency rate of 82%. Each model exhibited its own advantages and disadvantages, with a general lack of modeling methods combining diseases and syndromes of TCM and Western medicine. At present, the inducement factors used for animal models are relatively singular, mainly reflecting the etiology and pathogenesis of Western medicine, with insufficient correlation to the pathogenesis of TCM. The characteristics of TCM syndromes are not fully represented, and the consistency between TCM and Western medicine is generally not high. TCM has the advantage of a multi-dimensional syndrome differentiation and treatment approach. It is necessary to integrate the characteristics of diseases and syndromes of TCM and Western medicine, adopt multi-factor modeling methods to reflect the pathological process of CHF, improve existing models, and establish animal models of CHF that better align with the characteristics of clinical diseases and syndromes of TCM and Western medicine, so as to provide a reliable reference for clinical prevention and treatment.

Objective:To investigate the effective ingredients and molecular mechanisms of Qizao oral liquid in the treatment of lead poisoning through network pharmacology and molecular docking technology.Methods:December 2023, the effective ingredients and their corresponding targets of Qizao oral liquid were searched from the TCM Systems Pharmacology database. Swiss Target Prediction was used to predict corresponding potential target genes of compounds. Targets associated with lead poisoning were obtained from GeneCards and OMIM databases. Cytoscape 3.10.1 software was employed to construct a components and corresponding target network as well as a components and corresponding target network, followed by visualization and cluster analysis. GO and KEGG enrichment analyses were conducted using the Metascape database, resulting in the generation of a signaling pathway-target network diagram. Molecular docking analysis between the principal compounds and target proteins was performed using Autodock 4.2.6 and Pymol 2.2.0 software to validate their underlying molecular mechanisms.Results:A total of 114 active chemical components, 361 potential targets, 2501 lead poisoning targets, and 191 intersection targets of "Qizao oral liquid and lead poisoning" were screened. Further analysis revealed that there were 2091 entries for GO biological processes and 202 KEGG signaling pathways. Enrichment analysis showed that the key targets were mainly enriched in cancer, lipid and atherosclerosis, PI3K-Akt signaling pathways. Molecular docking showed that there were 14 combinations with binding energy<-5 kcal/mol, among which PIK3R1-β-sitosterol binding energy was -9.71 kcal/mol.Conclusion:The primary active components found in Qizao oral liquid, such as β-sitosterol, nuciferine, stephanine, and stigmasterol, have the potential to modulate key targets including PIK3R1, AKT1, TP53, and NFKB1. These components are capable of influencing the PI3K-Akt signaling pathway as well as lipid and atherosclerosis pathways in order to mitigate the adverse effects of lead exposure.

Objective To understand the epidemiological characteristics and risk factors of hospital-acquired pneumonia in elderly diabetic patients. Methods Elderly patients with diabetes mellitus who were hospitalized in the hospital were selected from October 2020 to October 2023 as the research subjects. The epidemiological characteristics of hospital-acquired pneumonia were analyzed, and the risk factors affecting hospital-acquired pneumonia in elderly patients with diabetes mellitus were analyzed . Results There were 65 cases of hospital-acquired pneumonia in 388 elderly patients with diabetes mellitus, with an incidence of 16.75%, of which 56.92% were males and 43.08% were females. The proportion of patients aged≥80 years was higher than that of patients aged<80 years. There were no significant differences in gender, body mass index, education level, course of diabetes mellitus, smoking history, drinking history, hypertension, coronary heart disease and anemia between groups (P>0.05), but significant differences were shown in age, hospitalization time, tracheal invasive operation, types of antibacterial drug use and dysphagia between both groups (P<0.05). Logistic multivariate analysis showed that age≥80 years old, hospitalization time≥30 d, tracheal invasive operation, use of antibacterial drugs≥ 2 types, and dysphagia were independent risk factors for hospital-acquired pneumonia in elderly diabetic patients (P<0.05). Conclusion The risk of hospital-acquired pneumonia is high in elderly patients with diabetes mellitus. Patients with age≥80 years old, hospitalization time≥30 days, tracheal invasive operation, abuse of antibacterial drugs and dysphagia are high-risk population. It is necessary to take active intervention measures for such patients.
