The 26th World Conference on Lung Cancer (WCLC) was held in Barcelona during September 6-9, 2025. As the world's largest and most influential academic meeting in the field of lung cancer, this year's congress unveiled long-term follow-up data from several pivotal studies and significant advances in novel therapeutic strategies. In the realm of targeted therapy, a next-generation combination strategy has been established as the new standard of care for the first-line treatment of patients with advanced epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC), demonstrating a significant improvement in overall survival. In immunotherapy, novel combination regimens have not only addressed the therapeutic challenge of acquired resistance to EGFR targeted therapies, but also shown clear long-term survival benefits in both the perioperative and locally advanced settings. These findings pave the way for shifting the treatment paradigm to earlier stages for patients with NSCLC. Antibody-drug conjugates have made remarkable strides in this field. They have shown outstanding efficacy in patients with specific resistance mutations and those with brain metastases, and have also demonstrated immense potential in treating patients with HER2-aberrant lung cancer and broader NSCLC populations. This offers new therapeutic options for patients with refractory lung cancer.However, significant challenges remain, including the heterogeneity of resistance mechanisms, the selection of optimal treatment regimens, and management strategies for special populations. Future research should focus on identifying novel precision biomarkers and optimizing therapeutic strategies to ultimately improve clinical outcomes for all patients with lung cancer.

OBJECTIVE To construct a preoperative medication reconciliation model assisted by a localized large language model （LLM） for gastric cancer and evaluate its clinical efficacy. METHODS A total of 249 gastric cancer patients with a history of continuous medication before admission in the Gastric Surgery Department of Jiangsu Cancer Hospital were retrospectively enrolled. Patients were divided into training set （154 cases） and validation set （95 cases） based on the order of time. Based on guidelines， drug package inserts， and other evidence， a standardized medication reconcili ation process and a structured knowledge base were constructed. DeepSeek-V3 LLM was deployed privately in the hospital， combined with retrieval-augmented generation technology， to achieve automated integration of medication information， risk screening， and generation of personalized recommendations. The quality of LLM-generated recommendations was evaluated using automatic metrics （BERT Score and ROUGE-1， 2， L） and manual scoring [seven-dimensional index （7DI） ] . Spearman correlation analysis was performed to explore the correlation between automatic scores and manual scores. Cronbach’s α coefficient was used to test the internal consistency of manual scoring results. The time consumed by manual and LLM-assisted medication reconciliation was compared across tasks of different difficulty levels （simple， moderate， and high）. RESULTS A structured knowledge base covering 8 major drug categories was finally established， covering common and high-risk preoperative medication scenarios and providing structured retrieval support for the LLM. For automatic evaluation， the precision， recall， and F1-score of BERT Score were 0.783±0.033， 0.811±0.038， and 0.796±0.028， respectively. The F1-scores of ROUGE-1， ROUGE-2 and ROUGE-L were 0.566±0.067， 0.338±0.076 and 0.468±0.082， respectively. The 7DI scores from three manual raters ranged from 32.06 to 33.45. The F1-score of automatic scoring was significantly positively correlated with the 7DI score of manual scoring （maximum coefficient of determination＝0.611， P ＜0.001）， and the internal consistency of manual scoring was good （Cronbach’s α ＝ 0.876）. In terms of efficiency， LLM-assisted medication reconciliation reduced time consumption by more than 90% compared with manual reconciliation in the simple， moderate， and high-difficulty groups （ P ＜0.001）. CONCLUSIONS The medication reconciliation model constructed based on a localized LLM and structured knowledge base shows high accuracy， consistency， and clinical applicability in complex preoperative medication scenarios for gastric cancer. It can improve the efficiency of medication reconciliation and reduce potential medication risks.

Objective: To investigate the association between uric acid level and elevated blood pressure among children and adolescents in Guangzhou, so as to provide a scientific basis for prevention and control of hypertension in the pediatric population. Methods: From March to December 2019, using stratified cluster random sampling, 3 626 children and adolescents aged 6-17 years without elevated blood pressure at baseline were recruited from 6 primary and secondary schools in Guangzhou. Serum uric acid levels were measured at baseline, and divided into four groups ( Q1-Q 4) based on age and sex specific quartiles for analyses. Two waves of follow up were carried out from October 2020 to May 2021 and from October 2021 to May 2022, respectively. Multilevel robust Poisson regression was used to evaluate the association between uric acid level and elevated blood pressure among children and adolescents. The additive interaction between high uric acid level and sugar sweetened beverage (SSB) intake on elevated blood pressure was assessed by stratification analysis and calculation of the relative excess risk due to interaction (RERI). Results: A total of 1 131 new cases of elevated blood pressure were identified during the two follow ups, with an incidence density of 130.5 cases 1 000 person years. Multilevel robust Poisson regression analysis showed that after adjusting for confounders such as gender, age and annual family income, compared with those in the uric acid Q 1 level, the risk of elevated blood pressure in individuals in the Q 4 level increased by 25% ( RR=1.25, 95%CI =1.08-1.44), and the risk of elevated systolic blood pressure increased by 20% ( RR=1.20, 95%CI =1.05-1.36) (both P <0.05); no statistical association was observed between uric acid and elevated diastolic blood pressure (all P >0.05). In the stratified analysis, the statistical associations of uric acid Q 4 level with elevated blood pressure ( RR=1.34, 95%CI =1.13-1.58) and elevated systolic blood pressure ( RR=1.33, 95%CI =1.14-1.55) were only observed in the group with SSB intake ≥ 250 mL/week (both P <0.05). The RERI values for the effect of uric acid Q 4 and Q 3 levels with SSB intake ≥ 250 mL/week on elevated systolic and diastolic blood pressure were 0.29 and 0.44 (both P <0.05). Conclusions High uric acid level is a risk factor for elevated blood pressure among children and adolescents, with a predominant effect on systolic blood pressure. High uric acid level and SSB intake synergistically promote the increase of blood pressure of children and adolescents.

Ischemic stroke （IS） is a serious cerebrovascular disease with high clinical incidence. Cerebral ischemia and hypoxia can induce metabolic reprogramming of cellular glycolysis. Hypoxia-inducible factor-1α （HIF-1α） serves as the core transcription factor in the hypoxic response. This article systematically reviews the molecular mechanisms of HIF-1α-mediated glycolytic reprogramming， elaborates on the effects of this metabolic alteration on the functional status of different immune cells， and summarizes the research progress of traditional Chinese medicine （TCM） interventions in this pathological process. HIF-1α reshapes glucose metabolic flux and shifts cellular metabolism toward glycolysis by regulating the transcription of key genes， including glucose transporters， glycolytic rate-limiting enzymes， and mitochondrial oxidative inhibitors. This metabolic disturbance can regulate the activation status， phenotypic differentiation， and functional remodeling of microglia， astrocytes， and peripherally infiltrated immune cells， thereby participating in the mediation of neuroinflammatory responses after IS. Moreover， multiple signaling pathways and the metabolite of glycolysis lactate can exert feedback regulation on this metabolic-immune process. Various active components of TCM and herbal formulas， such as astragaloside Ⅳ， salvianolic acid C， Ginkgo biloba extract， and Mailuo shutong pills， can inhibit abnormal glycolysis， reduce lactate accumulation， and restore the homeostasis of glucose oxidative metabolism by regulating signaling pathways including AMP-activated protein kinase/mammalian target of rapamycin/HIF-1α， HIF-1α/pyruvate kinase M2， and HIF-1α/lactate dehydrogenase A. Consequently， they effectively alleviate neuroimmune inflammation and attenuate ischemic brain injury.

OBJECTIVE To compare the efficacy and safety of different classes of antibacterial agents in hospitalized adult patients with community-acquired pneumonia （CAP）.METHODS PubMed， Embase，the Cochrane Library，Web of Science，CNKI，and Wanfang data were searched from inception to January 1，2026，to identify randomized controlled trials that evaluated different classes of antibacterial agents in hospitalized adults with CAP.After screening the literature， extracting the data， and evaluating the quality of the literature， a network meta-analysis was performed using Stata 18.0.RESULTS A total of 25 studies were included，involving 7 863 patients. In terms of efficacy，compared with carbapenems，penicillins，cephalosporins，macrolides，and pleuromutilins were associated with significantly higher treatment failure rates （ P ＜0.05），carbapenems and traditional tetracyclines were ranked as the top two by the surface under the cumulative ranking curve area （SUCRA）. No statistically significant differences were observed in mortality among the interventions （ P ＞0.05），carbapenems and other quinolones were ranked as the top two by SUCRA. In terms of safety，no statistically significant differences were observed among the interventions in the incidence of adverse events or discontinuation rates （ P ＞0.05）；traditional tetracyclines and novel tetracyclines were ranked as the top two by SUCRA for the incidence of adverse events，while novel tetracyclines and pleuromutilins were ranked as the top two by SUCRA for discontinuation rates.CONCLUSIONS Carbapenems significantly reduced the treatment failure rate in hospitalized adults with CAP. The safety profiles of all antibacterial agents were comparable， with novel tetracyclines showing a more favorable safety profile.
