The 2025 American Society of Clinical Oncology (ASCO) Annual Meeting was held in Chicago. At the meeting, researches on the treatment of epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) once again took the spotlight. Combination therapy strategies have demonstrated the potential to overcome resistance to EGFR tyrosine kinase inhibitor (EGFR-TKI) and prolong survival. Meanwhile, progress has also been made in individualized treatment strategies for young patients and those with fibrotic interstitial lung disease. However, the complexity of resistance mechanisms, special treatment considerations for different populations, and the impact of socioeconomic factors on treatment accessibility remain challenges in the field of EGFR-mutant NSCLC treatment. In the future, it is necessary to further explore more effective treatment regimens and expand the accessibility of precision medicine to maximize patient benefits.

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.

ObjectiveTo establish a model that can quickly identify the aroma components in different parts of Nardostachys jatamansi， so as to provide a quality control basis for the market circulation and clinical use of N. jatamansi. MethodsHeadspace solid-phase microextraction-gas chromatography-mass spectrometry（HS-SPME-GC-MS） combined with Smart aroma database and National Institute of Standards and Technology（NIST） database were used to characterize the aroma components in different parts of N. jatamansi， and the aroma components were quantified according to relative response factor（RRF） and three internal standards， and the markers of aroma differences in different parts of N. jatamansi were identified by orthogonal partial least squares-discriminant analysis（OPLS-DA） and cluster thermal analysis based on variable importance in the projection（VIP） value >1 and P<0.01. The odor data of different parts of N. jatamansi were collected by Heracles Ⅱ Neo ultra-fast gas phase electronic nose， and the correlation between compound types of aroma components collected by the ultra-fast gas phase electronic nose and the detection results of HS-SPME-GC-MS was investigated by drawing odor fingerprints and odor response radargrams. Chromatographic peak information with distinguishing ability≥0.700 and peak area≥200 was selected as sensor data， and the rapid identification model of different parts of N. jatamansi was established by principal component analysis（PCA）， discriminant factor alysis（DFA）， soft independent modeling of class analogies（SIMCA） and statistical quality control analysis（SQCA）. ResultsThe HS-SPME-GC-MS results showed that there were 28 common components in the underground and aboveground parts of N. jatamansi， of which 22 could be quantified and 12 significantly different components were screened out. Among these 12 components， the contents of five components（ethyl isovalerate， 2-pentylfuran， benzyl alcohol， nonanal and glacial acetic acid，） in the aboveground part of N. jatamansi were significantly higher than those in the underground part（P<0.01）， the contents of β-ionone， patchouli alcohol， α-caryophyllene， linalyl butyrate， valencene， 1，8-cineole and p-cymene in the underground part of N. jatamansi were significantly higher than those in the aboveground part（P<0.01）. Heracles Ⅱ Neo electronic nose results showed that the PCA discrimination index of the underground and aboveground parts of N. jatamansi was 82， and the contribution rates of the principal component factors were 99.94% and 99.89% when 2 and 3 principal components were extracted， respectively. The contribution rate of the discriminant factor 1 of the DFA model constructed on the basis of PCA was 100%， the validation score of the SIMCA model for discrimination of the two parts was 99， and SQCA could clearly distinguish different parts of N. jatamansi. ConclusionHS-SPME-GC-MS can clarify the differential markers of underground and aboveground parts of N. jatamansi. The four analytical models provided by Heracles Ⅱ Neo electronic nose（PCA， DFA， SIMCA and SQCA） can realize the rapid identification of different parts of N. jatamansi. Combining the two results， it is speculated that terpenes and carboxylic acids may be the main factors contributing to the difference in aroma between the underground and aboveground parts of N. jatamansi.

Objective To discover the mechanism by which miR-1287-5p affects the sensitivity of human esophageal cancer cell line KYSE30 to paclitaxel.Methods KYSE30 cells were divided into control group,group of transfected with miR-1287-5p mimic and inhibitor groups.RT-qPCR was used to detect the transfection rate.A paclitaxel-resistant cell line was established and cell viability and half inhibitory concentration(IC50)were detected by CCK-8 assay.The scratch test,Transwell chamber test and TUNEL method were used to evaluate the migration,invasion and apoptosis of cells.Western blot and immunocytochemistry(ICC)were used to detect the expression and localization of Akt and GSK-3β in cells.Results The expression level of miR-1287-5p in the miR-1287-5p mimic group was significantly higher than that in the miR-NC group and control group(P＜0.05),while the ex-pression level of the miR-1287-5p inhibitor group was significantly lower than that in miR-NC group and control group(P＜0.05).The cell survival rate of the miR-1287-5p mimic group was higher than that of the miR-NC group and the miR-1287-5p inhibitor group(P＜0.05).The cell migration rate and number of invasive cells in the miR-1287-5p mimic group were higher than those of the miR-NC group(P＜0.05),and the apoptosis rate was lower than that of the miR-NC group(P＜0.05).While in miR-1287-5p,the cell migration rate was lower and invasive cells were less in the inhibitor group and the apoptosis rate was increased as compared to the miR-NC group(P＜0.05).The expression of Akt and GSK-3β in the miR-1287-5p mimic group was significantly increased than in the miR-NC group(P＜0.05),while the expression in the miR-1287-5p inhibitor group was significantly inhibited than in miR-NC group(P＜0.05).Conclusions Up-regulation of miR-1287-5p can promote the migration and invasion of paclitaxel-resistant cell lines,inhibit cell apoptosis and thereby promote the development of paclitaxel resistance.

Objective To investigate the role of the neutrophil-to-lymphocyte ratio(NLR)in predicting the in-hospital mortality risk of patients with acute aortic dissection(AAD)in multicenter hospitals.Methods A multicenter retrospective cohort study was conducted.Clinical data were collected from 2642 AAD patients who were hospitalized in five teaching hospitals:Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology,Henan Provincial People's Hospital,Fuwai Central China Cardiovascular Hospital,the Third Affiliated Hospital of Xinxiang Medical University,and the Second Affiliated Hospital of Chongqing Medical University between August 2010 and December 2021.According to the quartiles of serum NLRlevels,the patients were divided into four groups:first quartile(Q1,n=660),second quartile(Q2,n=661),third quartile(Q3,n=661),and fourth quartile(Q4,n=660).The clinical characteristics and biochemical indicators of each group were compared.Partial correlation analysis was used to assess the relationship between NLR and cardiovascular parameters.Restricted cubic splines,Kaplan-Meier survival analysis,and Cox regression models were employed to evaluate the association between NLR levels and in-hospital mortality risk in AAD patients.Results The median age of all patients was 54[interquartile range(IQR):46-63]years,including 2096 males and 546 females.Compared with Q1-Q3 groups,patients inQ4group had a lower incidence of smoking history and diabetes history,and were more likely to have DeBakey type Ⅰ AAD(P＜0.05).Additionally,the levels of aspartate aminotransferase,high-density lipoprotein cholesterol,creatinine,and D-dimer in Q4 group were higher,while the levels of triglycerides and C-reactive protein(CRP)were lower(P＜0.01).The results of partial correlation analysis showed that the plasma NLR level was positively correlated with D-dimer(r=0.43,P＜0.01)and creatinine(r=0.16,P＜0.01).The restricted cubic spline function in the Cox model revealed a significant non-linear relationship between the plasma NLR level and clinical outcomes in AAD patients(P＜0.01).Kaplan-Meier survival analysis indicated that patients in Q4 group had the highest in-hospital mortality rate compared with Q1-Q3 groups(P＜0.0001).Furthermore,multivariate Cox regression analysis demonstrated that compared with Q1 group,the hazard ratio(HR)of NLR in Q4 group was 1.77(95％CI 1.33-2.37,P＜0.001),which was an independent risk factor for the primary endpoint events.Conclusion A higher plasma NLR level is significantly associated with the occurrence of cardiovascular events in AAD patients,and this association remains significant even after adjusting for potential confounding factors such as the multicenter visiting hospitals.

Objective To investigate the effect of Gd-hydroxyapatite(Gd-HA)stents with adipose mesenchymal cells(ADSCs)on the repair of knee articular cartilage defects.Methods To isolate,culture,and identify rabbit ADSCs by establishing a rabbit knee joint full-thickness cartilage defect model,a total of 18 rabbits were randomly divided into blank control group,Gd-HA scaffold group,and ADSCs+Gd-HA scaffold group.At week 12 and 24 after surgery,International Curtilage Repair Society(ICRS)score,HE,toluidine blue,modified red O bright green and ColⅡ were detected by immunohistochemical staining,then ColⅡand GAG mRNA expression levels were detected by O'Driscoll and Real-time PCR.ColⅡ protein expression was detected by Western blotting,GAG content was detected by DMMB,biomechanical strength was detected by indentation test,and PKH26 labeled ADSCs was used to trace the tissue engineering scaffold with Gd-HA composite ADSCs to evaluate the repair effect of rabbit knee cartilage defects.Results The ADSCs isolated and cultured in vitro showed good growth,stable phenotype and good directional differentiation through macroscopic observation and histological staining,it could be seen that the repair degree and effect of the knee joint full-thickness cartilage defect model implanted with Gd-HA scaffold group were better than those of the blank control group,while the cartilage repair situation of the ADSCs+Gd-HA scaffold group was better than that of the Gd-HA scaffold group(P＜0.05);The ICRS and improved O'Driscoll scores were higher than the other two groups(P＜0.05).Compared with the Gd-HA group,the ADSCs+Gd-HA group could produce ColⅡ and GAG during the process of cartilage repair,with stronger mechanical strength of the repaired tissue(P＜0.05);PKH26 labeled ADSCs were found in the repaired tissues of the ADSCs+Gd-HA group,and they were involved in the composition of newly formed tissues.Conclusion Gd-HA scaffold material combined with ADSCs has a good repair effect on full-thickness cartilage defects in the knee joint as a new type of biological material for repairing joint cartilage defects.
