The 2025 European Lung Cancer Congress (ELCC) convened in Paris, France, centering on the optimization and innovation of immunotherapy for non-small cell lung cancer (NSCLC). Key topics at the congress included the application strategies for perioperative immunotherapy, breakthroughs in combination therapy models for advanced NSCLC, and the emerging roles of biomarkers in predicting diverse treatment outcomes. This paper integrates data from several key pivotal studies to systematically analyze the clinical value of neoadjuvant therapy within the perioperative setting, the potential of targeted combination regimens, and the challenges of managing drug resistance, thus offering new directions for clinical practice.

The p60 subunit of the chromatin assembly factor-1 complex, that is, chromatin assembly factor-1 subunit B (CHAF1B), is a histone H3/H4 chaperone crucial for the transcriptional regulation of cell differentiation and self-renewal. CHAF1B is overexpressed in several cancers and may represent a potential target for cancer therapy. However, its expression and clinical significance in lung squamous-cell carcinoma (LUSC) remain unclear. In this study, we performed weighted gene correlation network analysis to analyze the Gene Expression Omnibus GSE68793 LUSC dataset and identified CHAF1B as one of the most important driver gene candidates. Immunohistochemical analysis of 126 LUSC tumor samples and 80 adjacent normal lung tissues showed the marked upregulation of CHAF1B in tumor tissues and the negative association of its expression level with patient survival outcomes. Silencing of CHAF1B suppressed LUSC proliferation in vitro and LUSC tumor growth in vivo. Furthermore, bulk RNA sequencing of CHAF1B knockdown cells indicated SET domain containing 7 (SETD7) as a significant CHAF1B target gene. In addition, CHAF1B competitively binds to the SETD7 promoter region and represses its transcription. Altogether, these results imply that CHAF1B plays a vital role in LUSC tumorigenesis and may represent a potential molecular target for this deadly disease.

Objective To explore the detection rate and distribution characteristics of gene mutations in pa-tients with non-small cell lung cancer,and to analyze their relationship with clinicopathological characteristics.Methods The genetic testing results and clinicopathological data of 213 patients with non-small cell lung cancer who underwent high-throughput genetic testing at the Gene Detection Center,Changchun Cancer Hos-pital from April 2020 to December 2023 were collected.High-throughput sequencing technology was used to detect mutations in 26 genes,and the relationship between the mutation frequency and its distribution and the clinicopathological characteristics of patients was analyzed.Results Among 213 patients with non-small cell lung cancer,192 cases(90.14％)had at least one gene mutation detected.Among them,the genes with rela-tively high mutation frequencies were TP53(60.56％),EGFR(46.48％),KRAS(14.55％),ALK fusion(11.74％),and PIK3CA(8.92％).There were 132 cases(30.28％)of evidence level for Class 1 drugs and 11 cases(2.52％)of evidence level for Class 2 drugs.The incidence of EGFR gene mutations was higher in women,non-smokers and patients with lung adenocarcinoma(P＜0.05).TP53 mutations usually occured in women,smokers and patients with stage Ⅳ.ALK mutations were more common in young patients,while KRAS mutations were more frequently seen in male smokers.Conclusion Analyzing the distribution charac-teristics of gene mutations in non-small cell lung cancer and their relationship with clinicopathological charac-teristics can provide a scientific basis for further optimizing genetic testing for patients with non-small cell lung cancer and offer guidance for clinical treatment.

Acute respiratory distress syndrome(ARDS)is a key disease in the field of clinical critical illness diagnosis and treatment.Its incidence and mortality rate have always remained high.Due to its high heterogeneity of the cause,specific biomarkers are still lacking in clinical diagnosis,and targeted treatment strategies for its core pathological links still have significant limitations.In view of this,the construction of an ARDS risk prediction model based on multi-dimensional risk factors can provide key evidence-based guidance for clinical medical staff to identify high-risk groups at ARDS in the early stage.This paper aims to review the research progress of ARDS risk factors and prediction models,in order to provide new ideas and references in building more accurate prediction models for ARDS.

Objective:To investigate the efficacy of alveolar lavage combined with montelukast in the treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and its effect on oxidative stress and inflammatory factors in patients.Methods:A prospective study was conducted involving 90 patients with AECOPD who were admitted to the Intensive Care Unit of Shan County Central Hospital from December 2021 to December 2022. The patients were randomly divided into a control group and an observation group, with 45 patients in each group, using the random number table method. The control group received conventional treatment, while the observation group was additionally treated with alveolar lavage combined with montelukast. Symptom score, Acute Physiology and Chronic Health Evaluation II score, overall response rate, serum levels of oxidative stress markers (malondialdehyde, 4-hydroxynonenal, and superoxide dismutase), and serum levels of inflammatory factors (C-reactive protein, tumor necrosis factor-α, interleukin-6, and procalcitonin) were compared between the two groups before and after treatment.Results:After treatment, the symptom scores for both groups decreased significantly compared with their respective scores before treatment ( t = 6.68, 11.32, both P < 0.05). After treatment, the symptom score in the observation group was significantly lower than that in the control group [(8.69 ± 0.84) points vs. (15.39 ± 1.18) points, t = 8.75, P < 0.05]. After treatment, the Acute Physiology and Chronic Health Evaluation II score in the observation group was significantly lower than that in the control group ( t = 9.19, P < 0.05). The overall response rate in the observation group was significantly higher than that in the control group [93.33% (42/45) vs. 75.56% (34/45), t = 4.56, P < 0.05]. After treatment, serum levels of 4-hydroxynonenal and malondialdehyde in the observation group were significantly lower than those in the control group ( t = 4.20, 5.15, both P < 0.05), while serum level of superoxide dismutase in the observation group was significantly higher than that in the control group ( t = 5.23, P < 0.05). After treatment, serum levels of C-reactive protein, tumor necrosis factor-α, interleukin-6, and procalcitonin in the observation group were significantly lower than those in the control group ( t = 6.86, 5.60, 8.75, 4.89, all P < 0.05). Conclusion:Alveolar lavage combined with montelukast can reduce clinical symptoms in patients with AECOPD, promote recovery, enhances clinical efficacy, decreases oxidative stress responses, increases the body's antioxidant capacity, lowers the expression of inflammatory factors, and reduces inflammatory responses.

Hyperoxia-induced acute lung injury (HALI) is an important complication of clinical oxygen therapy, which is mainly characterized by acute respiratory distress syndrome (ARDS) in adults and broncho-pulmonary dysplasia (BPD) in infants. HALI seriously affects the prognosis and quality of life of patients, so it has received more and more attention. However, the pathogenesis of HALI is complex and unclear, and there is no clear treatment method at present. Non-coding RNA (ncRNA) is an important type of functional RNA transcriptome. Due to the lack of effective open reading frame, ncRNA does not have the function of coding proteins. However, ncRNA can still regulate gene expression at multiple levels and affect the occurrence and development of many diseases. In recent years, a large number of in vitro and in vivo studies have shown that ncRNA is involved in the pathogenesis of HALI and is of great significance. This article reviews the expression and significance of ncRNA in HALI, in order to provide new diagnosis and treatment ideas for the prevention and treatment of HALI.

Objective:To compare the quality of sleep and rehabilitation after routine surgery versus day surgery in pediatric patients with snoring.Methods:This was a prospective study.Seventy pediatric patients with snoring, aged 4-6 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing adenoidectomy and/or tonsillectomy in the Guangzhou Women and Children′s Medical Center from March to June 2023, were divided into routine surgery group (group R) and day surgery group (group D), with 35 cases in each group. A sleep-detecting bracelet was used to monitor the sleep status. The proportion of deep sleep, light sleep and rapid eye movement, sleep continuity score and the maximum and minimum heart rate were recorded on the night before surgery, the first and second night after surgery. Rehabilitation was assessed using Quality of Recovery-15 at 1 day before surgery and 24 and 48 h and 28 days after surgery.Results:Compared with group R, the maximum heart rate at the night before surgery was significantly decreased, the proportion of light sleep on the second night after surgery was increased, the proportion of rapid eye movement sleep on the second night after surgery was decreased, the scores for items on " getting support from hospital doctors and nurses", " feeling comfortable and in control", and " having a feeling of general well-being" and the total score of Quality of Recovery-15 were significantly decreased at 24 and 48 h after operation, and the score for items on " feeling rested" and " have had a good sleep" at 48 h after surgery was decreased in group D ( P<0.05). Conclusions:Pediatric patients with snoring have poor quality of early sleep and rehabilitation after day surgery compared with routine surgery.

Objective To identify inflamm-aging related biomarkers in osteoarthritis(OA).Methods Microarray gene profiles of young and aging OA patients were obtained from the Gene Expression Omnibus(GEO)database and aging-related genes(ARGs)were obtained from the Human Aging Genome Resource(HAGR)database.The differentially expressed genes of young OA and older OA patients were screened and then intersected with ARGs to obtain the aging-related genes of OA.Enrichment analysis was performed to reveal the potential mechanisms of aging-related markers in OA.Three machine learning methods were used to identify core senescence markers of OA and the receiver operating characteristic(ROC)curve was used to assess their diagnostic performance.Peripheral blood mononuclear cells were collected from clinical OA patients to verify the expression of senescence-associated secretory phenotype(SASP)factors and senescence markers.Results A total of 45 senescence-related markers were obtained,which were mainly involved in the regulation of cellular senescence,the cell cycle,inflammatory response,etc.Through the screening with the three machine learning methods,5 core senescence biomarkers,including FOXO3,MCL1,SIRT3,STAG1,and S100A13,were obtained.A total of 20 cases of normal controls and 40 cases of OA patients,including 20 cases in the young patient group and 20 in the elderly patient group,were enrolled.Compared with those of the young patient group,C-reactive protein(CRP),interleukin(IL)-6,and IL-1β levels increased and IL-4 levels decreased in the elderly OA patient group(P＜0.01);FOXO3,MCL1,and SIRT3 mRNA expression decreased and STAG1 and S100A13 mRNA expression increased(P＜0.01).Pearson correlation analysis demonstrated that the selected markers were associated with some indicators,including erythrocyte sedimentation rate(ESR),IL-1β,IL-4,CRP,and IL-6.The area under the ROC curve of the 5 core aging genes was always greater than 0.8 and the C-index of the calibration curve in the nomogram prediction model was 0.755,which suggested the good calibration ability of the model.Conclusion FOXO3,MCL1,SIRT3,STAG1,and S100A13 may serve as novel diagnostic biomolecular markers and potential therapeutic targets for OA inflamm-aging.
