Sepsis is a life-threatening condition caused by a dysregulated response of the body in response to an infection that harms its tissues and organs.Interleukin-6(IL-6)is a significant component of the inflammatory response as part of the pa-thogenesis of sepsis.It aids in the development of Acute lung injury and,subse-quently,multiple organ dysfunction syndrome.This letter probes into the corre-lation between plasma IL-6 levels and the risk of developing acute lung injury and multiple organ dysfunction syndrome in critically ill patients with sepsis.While it shows promising results,limitations like its observational study design,a limited sample size,a single center involvement,single-time-point measurement,and a lack of a control group restrain its cogency.The study is a big step in identifying IL-6 as a biomarker to improve patient care. 展开更多

Background:To investigate SCL/TAL 1 interrupting locus(STIL)’s role and prognostic significance in lung adenocarcinoma(LUAD)progression,we examined STIL and E2 promoter binding factor 1(E2F1)expression and their impacts on LUAD prognosis using Gene Expression Profiling Interactive Analysis(GEPIA).Methods:Functional assays including CCK-8,wound-healing,5-ethynyl-2-deoxyuridine(EdU),Transwell assays,and flow cytometry,elucidated STIL and E2F1’s effects on cell viability,proliferation,apoptosis,and migration.Gene set enrichment analysis(GSEA)identified potential pathways,while metabolic assays assessed glucose metabolism.Results:Our findings reveal that STIL and E2F1 are overexpressed in LUAD,correlating with adverse outcomes.It enhances cell proliferation,migration,and invasion,and suppresses apoptosis,activating downstream of E2F1.Silencing E2F1 reversed the promotion effect of the STIL overexpression on cell viability and invasiveness.Importantly,STIL modulates glycolysis,influencing glucose consumption,lactate production,and energy balance in LUAD cells.Conclusion:Our model,incorporating STIL,age,and disease stage,robustly predicts patient prognosis,underscored STIL’s pivotal role in LUAD pathogenesis through metabolic reprogramming.This comprehensive approach not only confirms STIL’s prognostic value but also highlights its potential as a therapeutic target in LUAD. 展开更多

Background:Lung cancer is one of the deadliest cancers worldwide,creating a pressing need to develop novel drugs that inhibit oncogenic signaling pathways.Numerous studies have shown that berberine(BBR)has anti–lung cancer potential.We aimed to explore the anti–lung cancer effect of BBR and related mechanisms by targeting the glycogen synthase kinase 3β(GSK3β)/β-catenin pathway.Methods:Lung adenocarcinoma(LUAD)cells A549 and NCI-H1975 were treated with BBR.Results:Our results showed that BBR inhibited cell proliferation by decreasing c-Myc levels and induced cel cycle arrest in the G0/G1 phase by lowering cyclin D1 levels.BBR induced apoptosis by upregulating cleaved caspase 3 levels.BBR inhibited cell migration and invasion by decreasing N-cadherin levels.Furthermore,BBR upregulated the expression of GSK3βprotein and phospho-β-catenin proteins in the cytoplasm,while decreasing the expression ofβ-catenin protein.Next,LUAD cel s were exposed to CHIR-99021(a GSK3βinhibitor).This treatment led to an increase in c-Myc,cyclin D1,andβ-catenin levels at specific concentrations.BBR partially reversed the effects of CHIR-99021.Finally,LUAD cells were treated with CHIR-99021(4μmoL/L)combined with BBR(30 and 60μmoL/L)for 24 h.The expression of programmed death ligand 1(PD-L1)was assessed by Western blot analysis.Jurkat T cells and A549 cel s were cocultured for 24 h to examine the lactate dehydrogenase release rate.Results suggested that BBR suppressed the expression of PD-L1 and heightened the immune lethality of T cells.Conclusions:BBR suppressed the proliferative activity of LUAD cell lines A549 and NCI-H1975 in vitro,induced cell cycle arrest and cancer cel apoptosis in the G0/G1 stage,and repressed the migration and invasion of cancer cells.BBR reduced the PD-L1 protein expression and enhanced T-cell–mediated cytotoxicity.These effects appear to be related to BBR's regulation of the GSK3β/β-catenin pathway. 展开更多

As the leading cause of cancer-related deaths,lung cancer remains a noteworthy threat to human health.Although immunotherapies,such as immune checkpoint inhibitors(ICIs),have significantly increased the efficacy of lung cancer treatment,a significant percentage of patients are not sensitive to immunotherapies and patients who initially respond to treatment can quickly develop acquired drug resistance.Bispecific antibodies(bs Abs)bind two different antigens or epitopes simultaneously and have been shown to enhance antitumor efficacy with suitable safety profiles,thus attracting increasing attention as novel antitumor therapies.At present,in addition to the approved bs Ab,amivantamab,three novel bs Abs(KN046,AK112,and SHR-1701)are being evaluated in phase 3 clinical trials and many bs Abs are being evaluated in phase 1/2 clinical trials for patients with non-small cell lung cancer(NSCLC).Herein we present the structure,classification,and mechanism of action underlying bs Abs in NSCLC and introduce related clinical trials.Finally,we discuss challenges,potential solutions,and future prospects in the context of cancer treatment with bsAbs. 展开更多

In the present study,we aimed to investigate whether anlotinib reverses osimertinib resistance by inhibiting the formation of epithelial-mesenchymal transition(EMT)and angiogenesis.In a clinical case,anlotinib reversed osimertinib resistance in non-small cell lung cancer(NSCLC).Therefore,we performed immunohistochemical analyses on tumor tissues from three NSCLC patients with osimertinib resistance to analyze alterations in the expression levels of EMT markers and vascular endothelial growth factor A(VEGFA)before and after the development of osimertinib resistance.The results revealed the downregulation of E-cadherin,coupled with the upregulation of vimentin and VEGFA in tumor tissues of patients exhibiting osimertinib resistance,compared with those in tissues from patients before receiving osimertinib.Subsequently,we established osimertinib-resistant(Osi-R)cell lines and found that the Osi-R cells acquired EMT features.Next,we analyzed the synergistic effects of the combination therapy to verify whether anlotinib could reverse osimertinib resistance by inhibiting EMT.The expression levels of VEGFA and tube formation were analyzed in the combination group in vitro.Finally,we determined the reversal of osimertinib resistance by the combination of osimertinib and anlotinib in vivo using 20 nude mice.The combined treatment of osimertinib and anlotinib effectively prevented the metastasis of Osi-R cells,inhibited tumor growth,exerted antitumor activity,and ultimately reversed osimertinib resistance in mice.The co-administration of osimertinib and anlotinib demonstrated synergistic efficacy in inhibiting EMT and angiogenesis in three NSCLC patients,ultimately reversing osimertinib resistance. 展开更多

Background:Long noncoding RNA,LINC01106 exhibits high expression in lung adenocarcinoma(LUAD)tumor tissues,but its functional role and regulatory mechanism in LUAD cells remain unclear.Methods:LINC01106 expression was analyzed in LUAD tissues and its functional impact on LUAD cells was assessed.LUAD cells were silenced with sh-LINC01106 and injected into nude mice to investigate tumor growth.The downstream transcription factors and molecular mechanism were determined using the Human transcription factor database(TFDB)database and Gene Expression Profiling Interactive Analysis(GEPIA)database.Additionally,the impact of linc01106 on autophagy was analyzed by determining the expression of autophagy-related genes(ATGs)in LUAD cells.Results:Our results showed that LINC01106 exhibited upregulation in both LUAD tissues and cell lines.The silencing of LINC01106 demonstrated a suppressive effect on tumorigenesis in a xenograft mouse model of LUAD.Additionally,LINC01106 was found to recruit TATA-binding protein-associated factor 15(TAF15),an RNA-binding protein,thereby enhancing the mRNA stability of TEA domain transcription factor 4(TEAD4).In turn,TEAD4 served as a transcription factor that bound to the LINC01106 promoter and regulated its expression.Further assays indicated that LINC01106 promoted autophagy in LUAD cells by upregulating the expression of autophagy-related genes(ATGs).The silencing of LINC01106 in LUAD cells inhibited autophagy,and cell proliferation,and promoted apoptosis,which all were effectively reversed by ATG5 overexpression.Conclusions:Overall,LINC01106,transcriptionally activated by TEAD4,interacts with TAF15 to promote the stability of TEAD4 and upregulates the expression of ATGs,promoting malignancy of LUAD cells. 展开更多

BACKGROUND Lung cancer(LC)is one of the most prevalent cancers globally,with a high incidence among the elderly population.Elderly patients,particularly those with diabetes mellitus,are at an increased risk of postoperative complications,in-cluding pulmonary infections,due to weakened immune function and metabolic abnormalities.Postoperative pulmonary infection(PPI)is a predominant com-plication after thoracoscopic radical resection of LC,significantly affecting patient outcomes and increasing healthcare burdens.Determining risk factors for PPI in this vulnerable population is crucial for improving surgical outcomes and redu-cing infection rates.AIM To develop and validate a predictive model for PPI in elderly patients with dia-betes undergoing thoracoscopic radical resection for LC and to assess its reliability and validity.METHODS This retrospective study included 212 patients with LC who received treatment at our hospital from March 2015 to March 2022.General clinical information,sur-gical treatment details,and laboratory test results were collected and analyzed.Patients were grouped according to infection occurrence during the postoperative hospitalization period.Risk factors for PPIs were determined through logistic regression analysis,and a nomogram prediction model was established using R software to assess its predictive accuracy and performance.RESULTS Among the 212 patients[median age:72 years(interquartile range:60-82 years)],41 developed PPI(19.34%),with Gram-negative bacteria being the predominant pathogens(64.14%).Factors,such as age of≥70 years,presence of respiratory diseases,maximum tumor diameter of≥4 cm,stages II-III,receiving neoadjuvant chemotherapy of≥2 times preoperatively,surgery duration of≥3 hours,chest drainage tube placement duration of≥3.5 days,preoperative fasting blood glucose levels,hemoglobin A1c(HbA1c)levels,and multi-leaf resection,were markedly higher in the infection group than in the non-infection group.Conversely,forced expiratory volume in 1 second(FEV1)of≥80%and albumin(Alb)levels were lower in the infection group.Multivariate logistic regression analysis revealed that receiving neoadjuvant chemotherapy of≥2 times[odds ratio(OR)=2.987;P=0.036],maximum tumor diameter of≥4 cm(OR=3.959;P=0.013),multi-leaf resection(OR=3.18;P=0.036),preoperative FEV1 of≤80%(OR=3.305;P=0.029),and high HbA1c levels(OR=2.39;P=0.003)as key risk factors for PPI,whereas high Alb levels(OR=0.507;P<0.001)was protective.The nomogram model demonstrated excellent diagnostic ability(area under the curve=0.901,0.915),and calibration curves and decision curve analysis revealed good predictive performance and clinical applicability of the model.CONCLUSION The primary pathogens of PPI in elderly patients with diabetes and LC undergoing thoracoscopic radical resection are Gram-negative bacteria.The nomogram model,based on preoperative neoadjuvant chemotherapy cycles,maximum tumor diameter,range of resection,and preoperative FEV1,Alb,and HbA1c levels,shows high clinical value in predicting the risk of PPI in this patient population. 展开更多

The present study assessed the efficacy and safety of thoracic radiotherapy(TRT)following first-line chemotherapy or chemoimmunotherapy in patients with extensive-stage small cell lung cancer(ES-SCLC),focusing on the influence of different TRT timing strategies(consolidative vs.salvage)on survival rates.We retrospectively analyzed a total of 54 patients with ES-SCLC treated between January 2019 and July 2022.Patients receiving consolidative TRT(cTRT)within three months after completion of first-line treatment were compared with those receiving salvage TRT(sTRT)after disease progression.The primary endpoints were overall survival(OS),progression-free survival(PFS),locoregional-free survival(LRFS),and distant metastasis-free survival(DMFS);the secondary endpoint included safety.The cTRT group(n=41)showed significantly longer median OS(26.6 vs.14.8 months,P=0.048),PFS(12.9 vs.3.5 months,P<0.0001),and DMFS(10.7 vs.3.4 months,P=0.0044)than the sTRT group(n=13).Multivariate analysis revealed that cTRT was an independent,favorable prognostic factor.No significant differences in OS or LRFS were observed between high-dose(≥50 Gy)and low-dose(<50 Gy)TRT.Hematologic and respiratory toxicities were the most frequently reported adverse events,with acceptable tolerability.In conclusion,cTRT after chemoimmunotherapy significantly improves survival outcomes for ES-SCLC patients,and low-dose TRT may be a suitable option. 展开更多

Lycii Radicis Cortex(LRC)is a medicinal and food homologous plant with various pharmacological activities,including anti-tumor effects.This study explores the anti-tumor effect of LRC on non-small cell lung cancer(NSCLC)and its molecular mechanism using mice bearing Lewis lung carcinoma cells.LRC significantly suppressed the growth of NSCLC.Besides,RNA sequencing of mice tumors and hematoxylin&eosin and immunofluorescence staining revealed that LRC promoted the infiltration of T lymphocytes,specifically GZMB~+CD8~+T lymphocytes,in tumor tissues.The Gene Set Enrichment Analysis of spleen RNA indicated that LRC up-regulated PD-1-downstream pathways,suggesting that LRC exerted its effects through the PDL1/PD-1 pathway.Further experiments revealed that LRC interacted with PD-L1,blocking PD-L1/PD-1 binding and thus restoring the T cell killing activity on tumor cells.Together,these results support using LRC as healthy food to improve anti-tumor immunity in patients with NSCLC. 展开更多

BACKGROUND Colorectal cancer(CRC)ranks high among the most common types of malignant tumors.The primary cause of cancer-related mortality is metastasis,with lung metastases accounting for 32.9%of all cases of metastatic CRC(MCRC).However,cases of MCRC in the lungs,which present concurrently with primary peripheral lung adenocarcinoma,are exceptionally rare.CASE SUMMARY This report describes the case of a 52-year-old female patient who,following a colonoscopy,was diagnosed with moderately differentiated adenocarcinoma based on rectal mucosal biopsy findings.A preoperative chest computed tomography scan revealed a ground-glass nodule in the right lung and a small nodule(approximately 0.6 cm in diameter)in the extramural basal segment of the left lower lobe,which suggested multiple lung metastases from rectal cancer.Subsequent treatment and follow-up led to a diagnosis of rectal cancer with left lung metastasis and peripheral adenocarcinoma of the lower lobe of the right lung.CONCLUSION This case report describes the therapeutic journey of a patient with lung metastasis from rectal cancer in addition to primary peripheral adenocarcinoma,thus underscoring the critical roles of multidisciplinary collaboration,personalized treatment strategies,and comprehensive patient rehabilitation guidance. 展开更多

To improve their ... Lung cancer-derived exosomes are a kind of valuable and clinically-predictable biomarkers for lung cancer, but they have the limitations in individual differences when being applied in liquid biopsy. To improve their application value and accuracy in clinical diagnosis, a dual-labelled electrochemical method is herein reported for precise assessment of lung cancer-derived exosomes. To do so, two probes are prepared for the dual labeling of exosome membrane to run DNA assembly reactions: One is modified with cholesterol and can insert into exosome membrane through hydrophobic interaction;another one is linked with programmed death ligand-1(PD-L1) antibody and can bind to exosome surface-expressing PD-L1 via specific immunoreaction. Quantum dots-tagged signal strands are used to collect respective DNA products, and produce stripping signals corresponding to the amounts of total exosome and surfaceexpressing PD-L1, respectively. A wide linear relationship is established for the quantitative determination of lung cancer-derived exosomes in the range from 103to 1010particles/m L, whereas the ratiometric value of the two stripping signals is proven to have a better diagnostic use in screening and staging of lung cancer when being applied to clinical samples. Therefore, our method might provide a new insight into precise diagnosis of lung cancer, and offer sufficient information to refiect the biomarker level and guide the personalized treatment level even at an early stage in clinic. 展开更多

Lung cancer continues to be a leading cause of cancer-related deaths worldwide,emphasizing the critical need for improved diagnostic techniques.Early detection of lung tumors significantly increases the chances of successful treatment and survival.However,current diagnostic methods often fail to detect tumors at an early stage or to accurately pinpoint their location within the lung tissue.Single-model deep learning technologies for lung cancer detection,while beneficial,cannot capture the full range of features present in medical imaging data,leading to incomplete or inaccurate detection.Furthermore,it may not be robust enough to handle the wide variability in medical images due to different imaging conditions,patient anatomy,and tumor characteristics.To overcome these disadvantages,dual-model or multi-model approaches can be employed.This research focuses on enhancing the detection of lung cancer by utilizing a combination of two learning models:a Convolutional Neural Network(CNN)for categorization and the You Only Look Once(YOLOv8)architecture for real-time identification and pinpointing of tumors.CNNs automatically learn to extract hierarchical features from raw image data,capturing patterns such as edges,textures,and complex structures that are crucial for identifying lung cancer.YOLOv8 incorporates multiscale feature extraction,enabling the detection of tumors of varying sizes and scales within a single image.This is particularly beneficial for identifying small or irregularly shaped tumors that may be challenging to detect.Furthermore,through the utilization of cutting-edge data augmentation methods,such as Deep Convolutional Generative Adversarial Networks(DCGAN),the suggested approach can handle the issue of limited data and boost the models’ability to learn from diverse and comprehensive datasets.The combined method not only improved accuracy and localization but also ensured efficient real-time processing,which is crucial for practical clinical applications.The CNN achieved an accuracy of 97.67%in classifying lung tissues into healthy and cancerous categories.The YOLOv8 model achieved an Intersection over Union(IoU)score of 0.85 for tumor localization,reflecting high precision in detecting and marking tumor boundaries within the images.Finally,the incorporation of synthetic images generated by DCGAN led to a 10%improvement in both the CNN classification accuracy and YOLOv8 detection performance. 展开更多

Lung cancer is one of the main causes of cancer-related deaths globally,with non-small cell lung cancer(NSCLC)being the most prevalent histological subtype of lung cancer.Glutathione peroxidase 4(GPX4)is a crucial antioxidant enzyme that plays a role in regulating ferroptosis.It is also involved in a wide variety of biological processes,such as tumor cell growth invasion,migration,and resistance to drugs.This study comprehensively examined the role of GPX4 in NSCLC and investigated the clinical feasibility of targeting GPX4 for NSCLC treatment.We discovered that GPX4 influences the progression of NSCLC by modulating multiple signaling pathways,and that blocking GPX4 can trigger ferroptosis and increase the sensitivity to chemotherapy.As a result,GPX4 represents a prospective therapeutic target for NSCLC.Targeting GPX4 inhibits the development of NSCLC cells and decreases their resistance to treatment. 展开更多

BACKGROUND Small cell lung cancer(SCLC)is the most malignant type of lung cancer.Even in the latent period and early stage of the tumor,SCLC is prone to produce distant metastases with complex and diverse clinical manifestations.SCLC is most closely related to paraneoplastic syndrome,and some cases present as paraneoplastic peripheral neuropathy(PPN).PPN in SCLC appears early,lacks specificity,and often occurs before diagnosis of the primary tumor.It is easy to be misdiagnosed as a primary disease of the nervous system,leading to missed diagnosis and delayed diagnosis and treatment.CASE SUMMARY This paper reports two cases of SCLC with limb weakness as the first symptom.The first symptoms of one patient were rash,limb weakness,and abnormal electromyography.The patient was repeatedly referred to the hospital for limb weakness and rash for>1 year,during which time,treatment with hormones and immunosuppressants did not lead to significant improvement,and the condition gradually aggravated.The patient was later diagnosed with SCLC,and the dyskinesia did not worsen as the dermatomyositis improved after antineoplastic and hormone therapy.The second case presented with limb numbness and weakness as the first symptom,but the patient did not pay attention to it.Later,the patient was diagnosed with SCLC after facial edema caused by tumor thrombus invading the vein.However,he was diagnosed with extensive SCLC and died 1 year after diagnosis.CONCLUSION The two cases had PPN and abnormal electromyography,highlighting its correlation with early clinical indicators of SCLC. 展开更多

Numerous research conducted in recent years has revealed that gut microbial dysbiosis,such as modifications in composition and activity,might influence lung tissue homeostasis through specific pathways,thereby promoting susceptibility to lung diseases.The development and progression of lung cancer,as well as the effectiveness of immunotherapy are closely associated with gut flora and metabolites,which influence immunological and inflammatory responses.During abnormal proliferation,non-small cell lung cancer cells acquire more substances and energy by altering their own metabolic pathways.Glucose and amino acid metabolism reprogramming provide tumor cells with abundant ATP,carbon,and nitrogen sources,respectively,providing optimal conditions for tumor cell proliferation,invasion,and immune escape.This article reviews the relationship of immune response with gut flora and metabolic reprogramming in non-small cell lung cancer,and discusses the potential mechanisms by which gut flora and metabolic reprogramming affect the occurrence,development,and immunotherapy of non-small cell lung cancer,in order to provide new ideas for precision treatment of lung cancer patients. 展开更多

Interstitial lung diseases(ILD)encompass a diverse group of over 200 chronic pulmonary disorders characterized by varying degrees of inflammation and fibrosis,which can lead to severe respiratory impairment.Lung transplantation offers a crucial therapeutic option for patients with advanced ILD,extending survival and improving quality of life.This review explores optimal management strategies in both the pre-and post-transplant phases to enhance patient outcomes.Comprehensive pre-transplant evaluation,including pulmonary function testing,imaging,and comorbidity assessment,is critical for determining transplant eligibility and timing.Post-transplant care must focus on preventing complications such as primary graft dysfunction and chronic lung allograft dysfunction,managed through tailored immunosuppression and proactive monitoring.Recent advancements in diagnostic techniques and therapeutic approaches,including emerging technologies like ex vivo lung perfusion and precision medicine,promise to further improve outcomes.The ultimate goal is to establish an evidencebased,multidisciplinary framework for optimizing ILD management and lung transplantation. 展开更多
