Bronchial asthma （BA） is a common chronic inflammatory airway disease characterized by airway hyperresponsiveness and reversible airflow limitation. Lung macrophages （LMs）， as important effector cells of the innate immune system， play an important role in recognizing and engulfing pathogens， clearing harmful particles， and regulating immune responses. LMs can be polarized to M1 （pro-inflammatory） or M2 （anti-inflammatory） in different immune environments and participate in promoting or inhibiting inflammatory response， as well as lung parenchyma injury and repair （airway remodeling）， playing a key role in the BA occurrence and development. Regulating the polarization balance of macrophages can not only inhibit the inflammatory response in the airway and reduce airway hyperresponsiveness， but also improve airway remodeling and immune regulation， reduce airway mucus secretion， and alleviate the clinical BA symptoms. Traditional Chinese medicine and its active ingredients， especially polysaccharides and saponins， can regulate the polarization balance of M1/M2 macrophages. Traditional Chinese medicine compounds can balance the secretion of anti-inflammatory and pro-inflammatory factors by staging treatment and targeting the polarization state of M1/M2 macrophages， inhibit inflammatory response in the airway， reduce airway remodeling， and improve the BA symptoms. This paper summarized the research progress on the regulation of M1/M2 macrophage polarization by traditional Chinese medicine and its active ingredients， aiming to provide scientific evidence for the precise targeted therapy of BA.

Objective: To evaluate the efficacy of a short video based health education model in enhancing e-cigarette awareness among junior high school students, so as to provide empirical evidence for optimizing school based health education in the digital era. Methods: In December 2024, a cluster sampling method was applied to recruit 465 eighth grade students from a middle school in Kunming for a survey. The intervention was implemented through playing short videos produced by the research team in the classroom, and a self designed adolescent e-cigarette questionnaire was used to conduct assessments before and after intervention, along with qualitative interviews with 60 teachers and students by purposive sampling. Pre and post intervention outcomes were compared by using paired t-test and Chi-square test. Qualitative data underwent a three stage coding process of "open, axial, and selective coding" to construct an explanatory framework. Results: Quantitative analysis showed significant post intervention increases in both baseline awareness scores（92.1±6.6）and deep awareness scores (70.0±17.6) compared with pre intervention( 78.2± 14.0，46.1±20.5)( t =23.54，26.72，both P <0.05), both meeting the criteria for large effect sizes (Cohen s d =1.09, 1.24). The improvement in deep awareness was particularly pronounced, specifically regarding addictive ingredients, illicit additives(tiletamine,metomidate,etomidate), and misconceptions about smoking cessation efficacy ( χ 2=150.54,113.27,117.40,112.92, 69.93 , all P <0.01). Qualitative insights revealed that narrative transportation and visual enhancement were the core mechanisms of efficacy: 87.3% of students preferred contextualized narratives, 85.5% of students decoded cognitive bottlenecks more effectively because of visual enhancement, and 72.7% relied on short videos for micro learning. Conclusion Short video based health education can effectively enhance e-cigarette awareness among junior high school students, offering a pragmatically viable digital pathway for school based health education.

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 effects of enolase 1(ENO1)on the proliferation,migration,and invasion of gastric cancer cells and its underlying molecular mechanisms.Methods:The expression levels of ENO1 in human gastric cancer cell lines(HGC27,MKN-45,N-87,MGC803,BGC-823)and human gastric mucosal epithelial cells(GES-1)were detected using WB assay.Gene editing tools such as CRISPR and overexpression system were used to construct ENO1 knockdown and knockdown-rescue cell lines.Both MKN-45 and BGC-823 cells were grouped into control(Ctrl)group,ENO1 knockdown(ENO1 KD)group,and ENO1 knockdown-rescue(ENO1 KD-OE)group.The effects of ENO1 knockdown or ENO1 knockdown-rescue on the proliferation,migration,invasion,and apoptosis of gastric cancer cells were evaluated using colony formation assay,EdU staining,scratch wound healing assay,Transwell chamber assay and flow cytometry.Additionally,a xenograft model was established in nude mice,and the effects of ENO1 on tumor growth were monitored using small animal in vivo imaging and tumor tissue block measurement.ENO1 was silenced in MKN-45 cells employing RNA interference technology,and the downstream target genes of ENO1 were identified using RNA co-immunoprecipitation sequencing(RIP-seq)and bioinformatics analysis.The molecular mechanisms by which ENO1 regulates the proliferation,migration and invasion of gastric cancer cells was also analyzed.Results:ENO1 was significantly upregulated in gastric cancer cell lines(P<0.01 or P<0.001).ENO1 knockdown significantly inhibited proliferation,migration,and invasion while promoting apoptosis in MKN-45 and BGC-823 cells(P<0.001,P<0.000 1).Rescue experiments showed that restoring ENO1 expression significantly enhanced cell proliferation,migration,invasion,and inhibited apoptosis(P<0.05,P<0.01,P<0.001,P<0.000 1).In vivo experiments demonstrated that ENO1 knockdown significantly inhibited tumor growth in nude mice(P<0.000 1).The differentially expressed genes interacting with ENO1 protein were primarily enriched in pathways related to RNA splicing.Additionally,ENO1 protein was found to interact with the PKM gene,and their expressions showed a positive correlation in gastric cancer tissues(r=0.886).Conclusion:ENO1 is highly expressed in gastric cancer cells.ENO1 interacts with precursor mRNA of PKM to influence its RNA splicing process,thereby regulating PKM2 expression and promoting gastric cancer progression.

Objective:To systematically evaluate the risk prediction models for refeeding syndrome in critically ill patients in China and abroad, with the aim of providing feasible risk assessment tools for clinical healthcare professionals.Methods:A computerized search of PubMed, Embase, Web of Science, Cochrane Library, CINAHL, Proquest, Scopous, China Biomedical Literature Database, China National Knowledge Infrastructure (CNKI), Wanfang, and VIP was conducted for relevant literature from database inception to July 1, 2024. Two researchers independently reviewed the literature and extracted the relevant information. Quality assessment was performed using a risk of bias assessment tool specifically designed for predictive modeling.Results:A total of 8 papers were included, reporting 8 risk prediction models for refeeding syndrome in critically ill patients, with sample sizes ranging from 109 to 806 cases, outcome event rates from 22.5% to 69.8%, and area under the curve values from 0.74 to 0.95. The most frequently reported predictors included albumin (ALB), pre-albumin (PAB), blood potassium, use of diuretics, and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores.Conclusions:The risk prediction models for refeeding syndrome in critically ill patients have good predictive performance but are still in the development stage. A high-quality, low-bias clinically applicable model should be established through multicenter, large-sample, and standardized studies.

Objective:To analyze the incidence and spatiotemporal clustering of hepatitis B in China from 2006 to 2020 and provide reference for hepatitis B prevention and control.Methods:The incidence data of hepatitis B in 31 provinces (autonomous regions and municipalities) from 2006 to 2020 were collected from National Notifiable Infectious Disease Reporting System of China Information System for Disease Control and Prevention. The incidence trend analysis was conducted by using software Joinpoint 5.0.2, and the spatiotemporal scan analysis was performed by using software SaTScan 10.1.2.Results:From 2006 to 2020, a total of 1 049 546 cases of acute hepatitis B were reported in China. The average annual reported incidence rate was 5.17/100 000. The reported incidence rate showed a decreasing trend during this period. The incidence decreased from 3.00/100 000 to 0.41/100 000 in age group 0-14 years, from 14.15/100 000 to 3.44/100 000 in age group 15-34 years, and from 6.87/100 000 to 3.72/100 000 in age group ≥35 years, the differences were all significant (all P<0.001). From 2006 to 2020, a total of 10 732 017 cases of chronic hepatitis B were reported in China. The average annual reported incidence rate was 52.85/100 000. The reported incidence of chronic hepatitis B varied in different age groups, which decreased from 11.38/100 000 to 2.18/100 000 in age group 0-14 years, and from 73.17/100 000 to 61.40/100 000 in age group 15-34 years, while increased from 48.07/100 000 to 90.75/100 000 in age group ≥35 years, the differences were all significant (all P<0.05). Spatiotemporal scan analysis indicated that the age of reported acute hepatitis B cases became older over time, and the regions with high-incidence gradually shifted from western China to southwestern China. The overall reported incidence of chronic hepatitis B in those aged ≥35 years showed an upward trend, and the regions with high-incidence were mainly found in coastal area in southeastern China and in southwestern China. Conclusions:From 2006 to 2020, the overall reported incidence of acute hepatitis B in China showed a continuous downward trend, while the reported incidence of chronic hepatitis B in those aged ≥35 years showed an upward trend. It indicated that the need to improve the diagnosis and treatment of chronic hepatitis B in adults in coastal area in southeastern China and southwestern China.

Pelvic organ prolapse (POP), whose etiology is influenced by genetic and clinical risk factors, considerably impacts women's quality of life. However, the genetic underpinnings in non-European populations and comprehensive risk models integrating genetic and clinical factors remain underexplored. This study constructed the first polygenic risk score (PRS) for POP in the Chinese population by utilizing 20 disease-associated variants from the largest existing genome-wide association study. We analyzed a discovery cohort of 576 cases and 623 controls and a validation cohort of 264 cases and 200 controls. Results showed that the case group exhibited a significantly higher PRS than the control group. Moreover, the odds ratio of the top 10% risk group was 2.6 times higher than that of the bottom 10%. A high PRS was significantly correlated with POP occurrence in women older than 50 years old and in those with one or no childbirths. As far as we know, the integrated prediction model, which combined PRS and clinical risk factors, demonstrated better predictive accuracy than other existing PRS models. This combined risk assessment model serves as a robust tool for POP risk prediction and stratification, thereby offering insights into individualized preventive measures and treatment strategies in future clinical practice.

Salmonellosis represents a global epidemic, and the emergence of extensively drug-resistant (XDR) Salmonella and its sustained transmission worldwide constitutes a significant public health concern. Flagellum-mediated motility serves as a crucial virulence trait of Salmonella that guides the pathogen toward the epithelial surface, enhancing gut colonization. Artemisia argyit essential oil, a traditional herb extract, demonstrates efficacy in treating inflammation-related symptoms and diseases; however, its effects on flagellum assembly and expression mechanisms in anti-Salmonella activity remain inadequately explored. This study aimed to elucidate the mechanism by which Artemisia argyit essential oil addresses Salmonella infections. Network pharmacological analysis revealed that Traditional Chinese Medicine (TCM) Artemisia argyit exhibited anti-Salmonella infection potential and inhibited flagellum-dependent motility. The application of Artemisia argyit essential oil induced notable motility defects through the downregulation of flagellar and fimbriae expression. Moreover, it significantly reduced Salmonella-infected cell damage by interfering with flagellum-mediated Salmonella colonization. In vivo studies demonstrated that Artemisia argyit essential oil administration effectively alleviated Salmonella infection symptoms by reducing bacterial loads, inhibiting interleukin-1 beta (IL-1β), IL-6, and tumor necrosis factor-alpha (TNF-α) production, and diminishing pathological injury. Gas chromatography-mass spectrometry (GC-MS) analysis identified forty-three compounds in Artemisia argyit essential oil, with their corresponding targets and active ingredients predicted. Investigation of an in vivo model of Salmonella infection using the active ingredient demonstrated that alpha-cedrene ameliorated Salmonella infection. These findings suggest the potential application of Artemisia argyit essential oil in controlling Salmonella, the predominant food-borne pathogen.
