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.

The 2025 American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO-GI) was held from January 23 to 25, 2025. Several significant studies on the treatment of esophageal and gastroesophageal junction (GEJ) cancer were presented at the symposium, highlighting notable advances, particularly in the perioperative and advanced settings. Immunotherapy has demonstrated significant promise in the neoadjuvant treatment of esophageal cancer, showing potential to become a standard treatment. Furthermore, the long-term survival benefits of combining immunotherapy with chemotherapy for advanced GEJ cancer were further validated. This article summarizes and interprets the researches presented at the symposium concerning perioperative and advanced treatments for esophageal and GEJ cancers.

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.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

MRGPRX2 antagonists possess the potential for the treatment of allergic rhinitis, atopic dermatitis, and chronic urticaria. Previously, we identified a class of diaryl urea (DPU) MRGPRX2 antagonists with sub-micromolar IC₅₀ values in vitro. However, the structure-activity relationship remains unclear. Herein, we adopted a "relative symmetry with electronegativity of different key-groups" strategy for further modification of DPUs to achieve a promising MRGPRX2 antagonist with higher activity and safety. Electrostatic potential energy analysis and biological evaluation revealed that B-1023 and B-5023, that possess relatively symmetric electron-withdrawing substituents, remarkable inhibited mast cell degranulation at a sub-micromolar IC₅₀ in vitro and alleviated anaphylactic symptoms. Furthermore, B-1023, mitigated antigen-induced pulmonary inflammation (AIPI) in mice and competitively bonded to MRGPRX2. In summary, the "relative symmetry with electronegativity of different key-groups" strategy provided a drug design pattern for MRGPRX2 antagonists and identified promising antiallergic precursors for AIPI treatment.

Idiopathic pulmonary fibrosis (IPF), a chronic interstitial lung disease, is characterized by aberrant wound healing, excessive scarring and the formation of myofibroblastic foci. Although the role of alternative splicing (AS) in the pathogenesis of organ fibrosis has garnered increasing attention, its specific contribution to pulmonary fibrosis remains incompletely understood. In this study, we identified an up-regulation of serine/arginine-rich splicing factor 7 (SRSF7) in lung fibroblasts derived from IPF patients and a bleomycin (BLM)-induced mouse model, and further characterized its functional role in both human fetal lung fibroblasts and mice. We demonstrated that enhanced expression of Srsf7 in mice spontaneously induced alveolar collagen accumulation. Mechanistically, we investigated alternative splicing events and revealed that SRSF7 modulates the alternative splicing of pyruvate kinase (PKM), leading to metabolic dysregulation and fibroblast activation. In vivo studies showed that fibroblast-specific knockout of Srsf7 in conditional knockout mice conferred resistance to bleomycin-induced pulmonary fibrosis. Importantly, through drug screening, we identified lomitapide as a novel modulator of SRSF7, which effectively mitigated experimental pulmonary fibrosis. Collectively, our findings elucidate a molecular pathway by which SRSF7 drives fibroblast metabolic dysregulation and propose a potential therapeutic strategy for pulmonary fibrosis.

Objective To investigate the correlation between apathy and imaging markers in pa-tients with aCSVD.Methods A total of 143 patients diagnosed with aCSVD and hospitalized in the Department of Neurology of the First Affiliated Hospital of Baotou Medical College,Inner Mongolia University of Science and Technology from August 2023 to August 2024 were continu-ously included as the study objects.According to MAES,they were divided into an apathetic group(MAES score＞14,68 cases)and a non-apathetic group(MAES score ≤14,75 cases).The clinical data and imaging markers were compared between the two groups.Results The apathetic group had significantly older age and larger ratio of hypertension,but shorter years of education and lower MAES score than the non-apathetic group(P＜0.05,P＜0.01).The apathetic group also had notably higher Fazekas score of white matter hyperintensity(WMH),larger recent small sub-cortical infarct(RSSI),lacunar infarct(LI),and perivascular space(PVS)in the basal ganglia and the centrum semiovale,more obvious cerebral atrophy and cerebral microbleed(CMB),and high-er total imaging burden score when compared with the non-apathetic group(P＜0.01).In the aCSVD patients,the MAES score was positively correlated with WMH Fazekas score,RSSI,LI,basal ganglia PVS,centrum semiovale PVS,cerebral atrophy,CMB,and total imaging burden score(P＜0.01).WMH Fazekas score was an independent risk factor for apathy in the aCSVD patients(OR=2.218,95％CI:1.343-3.664,P=0.002).Conclusion The higher the score of ima-ging markers in patients with aCSVD,the more severe the apathy.

Objective:To explore the differences in the whole-brain functional connectivity characteristics of magnetoencephalography gamma sub-band in resting state between patients with depression with high and low suicidal ideation.Methods:Clinical data of 60 patients with depression (depression group) who visited the Department of Psychiatry, Nanjing Brain Hospital Affiliated to Nanjing Medical University from October 2021 to June 2024 were prospectively collected, including 20 males and 40 females aged 16-41 years. During the same period, 75 healthy controls (healthy control group) were recruited, matched for gender and age, comprising 33 males and 42 females, aged 18-43 years. The Hamilton Depression Scale-17 items (HAMD-17) was used to assess the degree of depression in patients, and the score of the third item was used to divide the patients into a high suicidal ideation group of 37 cases (2-3 points) and a low suicidal ideation group of 23 cases (0-1 points). The Beck Scale for Suicide Ideation-Chinese Version (BSI-CV) was used to assess the intensity of suicidal ideation in patients in the last week and at the most severe stage. Brain imaging data of the subjects were collected using a CTF-275 channel magnetoencephalography device and a 3 T magnetic resonance imaging device. The functional connectivity matrix of the gamma sub-band depression group, healthy control group, high suicidal ideation group, and low suicidal ideation group was calculated using the envelope correlation method. The network-based statistics (NBS) algorithm was used to correct for multiple comparisons and compare the differences in brain network functional connectivity between the depression group/healthy control group and between the high/low suicidal ideation groups.Results:Compared with the healthy control group, the functional connectivity between the bilateral middle frontal gyrus, right inferior frontal gyrus orbital part, right anterior cingulate gyrus, left middle frontal gyrus orbital part, and right superior parietal lobule in the depression group was significantly enhanced in the low gamma frequency band (30-60 Hz) ( θ=3, P=0.042). Compared with the low suicidal ideation group, the functional connectivity between the right amygdala as a central node and the right superior frontal gyrus, left hippocampus, right upper temporal pole, and left transverse temporal gyrus in the high suicidal ideation group was significantly enhanced in the high gamma frequency band (60-90 Hz) ( θ=3, P=0.049). Conclusion:In the low gamma frequency band, patients with depression have neural dysfunction mainly in the frontal lobe. In the high gamma frequency band, patients with high suicidal ideation have functional connectivity abnormalities centered on the amygdala.

BACKGROUND:With the development of computer-aided design and computer-aided manufacturing technology,zirconia abutments with a titanium base are widely used in clinic due to its good application advantages,but there are still some problems and a lack of consensus design standards. OBJECTIVE:To review the fabrication methods of Ti-base zirconia abutment,and the effect of abutment connection,emergence design,abutment angle,and bonding on mechanical properties of Ti-base zirconia abutment. METHODS:Relevant literature published from 2010 to 2023 was searched in CNKI and PubMed databases with the search terms"zirconia abutment,titanium base"in Chinese and English,respectively.The search time limit was extended for some classical literature.The relevant literature was obtained through inclusion and exclusion criteria,and 57 eligible documents were included for review. RESULTS AND CONCLUSION:It is recommended that clinicians try to select antirotational titanium bases or rotational titanium bases with a Morse taper connection.Implants should be placed in the correct axial angulation of not more than 15° or with an inclination to the palatal side when using angled zirconia abutments.When a≥30° labial inclination is followed for implant placement,the bite force must be decreased effectively to reduce the risk of mechanical and biological complications of implants,abutments,and prostheses.Ti-base zirconia abutments with a higher gingival height should be selected,and its restorative angle should not exceed 40°.Multilink Hybrid Abutment could be the first choice for extraoral bonding of zirconia abutment to titanium bases.
