Surgical treatment is one of the key approaches for non-small cell lung cancer (NSCLC). Regular postoperative follow-up is crucial for early detection and timely management of tumor recurrence, metastasis, or second primary tumors. A scientifically sound and reasonable follow-up strategy not only extends patient survival but also significantly improves quality of life, thereby enhancing overall prognosis. This consensus aims to build upon the previous version by incorporating the latest clinical research advancements and refining postoperative follow-up protocols for early-stage NSCLC patients based on different treatment modalities. It provides a scientific and practical reference for clinicians involved in the postoperative follow-up management of NSCLC. By optimizing follow-up strategies, this consensus seeks to promote the standardization and normalization of lung cancer diagnosis and treatment in China, helping more patients receive high-quality care and long-term management. Additionally, the release of this consensus is expected to provide insights for related research and clinical practice both domestically and internationally, driving continuous development and innovation in the field of postoperative management for NSCLC.

Conventional chemotherapy based on cytotoxic drugs is facing tough challenges recently following the advances of monoclonal antibodies and molecularly targeted drugs. It is critical to inspire new potential to remodel the value of this classical therapeutic strategy. Here, we fabricate bisphosphonate coordination lipid nanogranules (BC-LNPs) and load paclitaxel (PTX) to boost the chemo- and immuno-therapeutic synergism of cytotoxic drugs. Alendronate in BC-LNPs@PTX, a bisphosphonate to block mevalonate metabolism, works as both the structure and drug constituent in nanogranules, where alendronate coordinated with calcium ions to form the particle core. The synergy of alendronate enhances the efficacy of paclitaxel, suppresses tumor metastasis, and alters the cytotoxic mechanism. Differing from the paclitaxel-induced apoptosis, the involvement of alendronate inhibits the mevalonate metabolism, changes the mitochondrial morphology, disturbs the redox homeostasis, and causes the accumulation of mitochondrial ROS and lethal lipid peroxides (LPO). These factors finally trigger the ferroptosis of tumor cells, an immunogenic cell death mode, which remodels the suppressive tumor immune microenvironment and synergizes with immunotherapy. Therefore, by switching paclitaxel-induced apoptosis to mevalonate metabolism-triggered ferroptosis, BC-LNPs@PTX provides new insight into the development of cytotoxic drugs and highlights the potential of metabolism regulation in cancer therapy.

OBJECTIVE To explore the safety， effectiveness， and cost-effectiveness of elderly patients with sarcopenia receiving Shenling baizhu powder combined with nutrition and exercise intervention， providing a reference for rational clinical drug use. METHODS A total of 237 elderly sarcopenia patients were randomly assigned to an observation group （118 cases） and a control group （119 cases）. Both groups of patients received nutrition and exercise intervention； the observation group added Shenling baizhu powder （6 g each time， three times daily） on this basis. The safety， effectiveness， and cost-effectiveness of the two plans were compared after 3 months. RESULTS Both groups of patients completed the follow-up. Before intervention， no significant difference was observed in skeletal muscle index （SMI）， grip strength， and 6-minute walk test （6MWT） speed between the two groups （P＞0.05）. After intervention， the grip strength of the patients in the observation group was significantly greater than that of the control group （25.05 kg vs. 23.18 kg， P＜0.01）； the treatment response rate of sarcopenia， SMI， and 6MWT speed were higher than those of the control group， butthe differences were not statistically significant （P＞0.05）. The adverse reaction/event rate of the patients in the observation group was lower than that of the control group （14.41% vs. 16.81%， P＝0.611）， but the difference was not statistically significant. Compared with the control group’s plan， the cost of the observation group’s plan was higher （981.25 yuan vs. 913.94 yuan）， and the effect was better （effectiveness rate： 0.618 6 vs. 0.563 0）， with an incremental cost-effectiveness ratio of 1 210.61 yuan. The results of the sensitivity analysis were consistent with the cost-effectiveness analysis results. CONCLUSION Elderly patients with sarcopenia who receive Shenling baizhu powder combined with nutrition and exercise intervention can significantly strengthen grip strength without increasing the incidence of adverse reactions/events. Compared with the control group plan， the observation group needs to spend an additional 1 210.61 yuan for each additional effective patient with sarcopenia.

Background::Bladder cancer, characterized by a high potential of tumor recurrence, has high lifelong monitoring and treatment costs. To date, tumor cells with intrinsic softness have been identified to function as cancer stem cells in several cancer types. Nonetheless, the existence of soft tumor cells in bladder tumors remains elusive. Thus, our study aimed to develop a microbarrier microfluidic chip to efficiently isolate deformable tumor cells from distinct types of bladder cancer cells.Methods::The stiffness of bladder cancer cells was determined by atomic force microscopy (AFM). The modified microfluidic chip was utilized to separate soft cells, and the 3D Matrigel culture system was to maintain the softness of tumor cells. Expression patterns of integrin β8 (ITGB8), protein kinase B (AKT), and mammalian target of rapamycin (mTOR) were determined by Western blotting. Double immunostaining was conducted to examine the interaction between F-actin and tripartite motif containing 59 (TRIM59). The stem-cell-like characteristics of soft cells were explored by colony formation assay and in vivo studies upon xenografted tumor models. Results::Using our newly designed microfluidic approach, we identified a small fraction of soft tumor cells in bladder cancer cells. More importantly, the existence of soft tumor cells was confirmed in clinical human bladder cancer specimens, in which the number of soft tumor cells was associated with tumor relapse. Furthermore, we demonstrated that the biomechanical stimuli arising from 3D Matrigel activated the F-actin/ITGB8/TRIM59/AKT/mTOR/glycolysis pathways to enhance the softness and tumorigenic capacity of tumor cells. Simultaneously, we detected a remarkable up-regulation in ITGB8, TRIM59, and phospho-AKT in clinical bladder recurrent tumors compared with their non-recurrent counterparts.Conclusions::The ITGB8/TRIM59/AKT/mTOR/glycolysis axis plays a crucial role in modulating tumor softness and stemness. Meanwhile, the soft tumor cells become more sensitive to chemotherapy after stiffening, that offers new insights for hampering tumor progression and recurrence.

Background::Although some well-established oncogenes are involved in cancer initiation and progression such as prostate cancer (PCa), the long tail of cancer genes remains to be defined. Goosecoid ( GSC) has been implicated in cancer development. However, the comprehensive biological role of GSC in pan-cancer, specifically in PCa, remains unexplored. The aim of this study was to investigate the role of GSC in PCa development. Methods::We performed a systematic bioinformatics exploration of GSC using datasets from The Cancer Genome Atlas, Genotype-Tissue Expression, Gene Expression Omnibus, German Cancer Research Center, and our in-house cohorts. First, we evaluated the expression of GSC and its association with patient prognosis, and identified GSC-relevant genetic alterations in cancers. Further, we focused on the clinical characterization and prognostic analysis of GSC in PCa. To understand the transcriptional regulation of GSC by E2F transcription factor 1 ( E2F1), we performed chromatin immunoprecipitation quantitative polymerase chain reaction (qPCR). Functional experiments were conducted to validate the effect of GSC on the tumor cellular phenotype and sensitivity to trametinib. Results::GSC expression was elevated in various tumors and significantly correlated with patient prognosis. The alterations of GSC contribute to the progression of various tumors especially in PCa. Patients with PCa and high GSC expression exhibited worse progression-free survival and biochemical recurrence outcomes. Further, GSC upregulation in patients with PCa was mostly accompanied with higher Gleason score, advanced tumor stage, lymph node metastasis, and elevated prostate-specific antigen (PSA) levels. Mechanistically, the transcription factor, E2F1, stimulates GSC by binding to its promoter region. Detailed experiments further demonstrated that GSC acted as an oncogene and influenced the response of PCa cells to trametinib treatment. Conclusions::GSC was highly overexpressed and strongly correlated with patient prognosis in PCa. We found that GSC, regulated by E2F1, acted as an oncogene and impeded the therapeutic efficacy of trametinib in PCa.

Objective To observe the neuropsychiatric behavioral performance of kainic acid(KA)-induced epilepsy rats;investigate gender differences in acute seizure and behavioral performance tasks relating to sense,motor,learning,and memory in the remission phase;and explore the potential neurobiological mechanisms of action.Methods Healthy SD rats aged 4 weeks were randomly divided into control and model groups,with 22 rats in each group(11 males and 11 females).An epileptic rat model was induced by intraperitoneal injection of KA.Seizure latency and frequency within 2 hours of KA injection were observed,seizure grade was assessed using the Racine grade standard,and a cortical electroencephalogram(EEG)was recorded.Behavioral performance was observed in a series of tasks including open field testing,balance beam walking,elevated plus maze,Y-maze,and novel object recognition.The level of GABA in the hippocampus was detected by ELISA,injury to hippocampal neurons was observed by Nissl staining,and the protein expression of synapsin-1 and synaptotagmin 1 in the hippocampus were detected by Western Blot.Results Both male and female rats presented typical epileptic behaviors after KA injection.However,compared with the effects in males,the latency of the first seizure(P=0.014)and Ⅳ～Ⅴ grading in female model rats were more pronounced(P＜0.01),and the frequency of epileptic seizures within 2 hours was significantly reduced(P=0.019).In the open field testing,KA-induced epileptic rats presented more motor but fewer hedonic behaviors,as indicated by the decrease in total movement distance in the central area,compared with the control group.Moreover,grooming frequency was significantly reduced in the female model rats compared with not only that in the control but also that in male model rats(P＜0.01).The model rats spent more time completing and had a higher score in the balance beam walking task,indicating their poorer stability and balance.In the elevated plus maze,the exploration times of male model rats in the closed arm was increased.The preference index of rats for the novel arm or object decreased in the Y-maze and novel object recognition,suggesting impairments to their learning and memory abilities.Moreover,neuronal injuries were found in the hippocampus of the model rats that were accompanied with a decline in GABA concentration and protein expression of synapsin-1 and synaptotagmin 1,with no gender differences.Conclusions Intraperitoneal injection of KA successfully induced an epilepsy rat model.However,there was a gender difference in the characters of acute seizures and performance of sensory,motor,and learning memory during epileptic remission.There was no gender differences in the hippocampal GABA concentration or expression of synaptic plasticity-related proteins,and thus no evidence was found for the mechanisms underlying the gender differences.

Objective:To investigate the effects of microRNA (miR) -125b on the proliferation and phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway of hepatocellular carcinoma (HCC) cell by targeting Polo like kinases (PLK4).Methods:The tumor tissues and adjacent tissues of 65 patients with HCC were collected from March 2022 to March 2023 in Tianjin Medical University Cancer Hospital, including 33 males and 32 females, aged (60.1±5.6) years. The expressions of miR-125a and miR-125b in liver cancer, adjacent tissues and liver cancer cells were detected by fluorescence quantitative polymerase chain reaction. Low expression liver cancer cell was selected to transfect negative control (NC) sequences of miR, miR-125a and miR-125b. Subsequently, miR-NC and NC plasmid, miR-125b sequence and NC plasmid, and miR-125b sequence and PLK4 plasmid were co-transfected. Cell proliferation was detected by cell counting assay, the expression of PLK4, phosphorylated PI3K (p-PI3K) and phosphorylated Akt (p-Akt) was detected by Western blot, and miR-125b-targeting PLK4 were detected by bioinformatics analysis and dual luciferase reporter gene.Results:The relative expressions of miR-125a and miR-125b in HCC patients were (0.62±0.08) and (0.58±0.07), respectively, lower than those in adjacent tissues (1.00±0.12) and (1.00±0.13), and the differences were statistically significant ( t=21.24, 22.93, P=0.005, P<0.001). HepG2 cells with low expression of miR-125a and miR-125b and miR-125b targeting PI3K/Akt were selected for transfection. Bioinformatic analysis and dual luciferase reporter gene assay confirmed that miR-125b binds to PLK4. Overexpression of miR-125b could inhibit the proliferation of HepG2 cells and the expression of p-PI3K and p-Akt, while overexpression of PLK4 could partially reverse the proliferation inhibition caused by miR-125b and the expression of p-PI3K and p-Akt, (0.91±0.07) vs(0.41±0.04), (0.97±0.08) vs (0.32±0.03)( t=13.87, 17.01, both P<0.001). Conclusion:The inhibitory effect of miR-125b on HepG2 cell proliferation and PI3K/Akt signaling pathway is partly mediated by targeted inhibition of PLK4.

Objective:To screen key genes that co-regulate immune and mitochondrial energy metabolism through bioinformatics methods and to investigate the relationship between the key genes and immune infiltration.Methods:A total of 671 glioma samples (the tumor group) and 5 non-tumor brain tissue samples (the control group) were collected from the Cancer Genome Atlas (TCGA) database on November 13, 2023. Through a comprehensive search of the GeneCards database and immune-related genes (IRG) and mitochondrial energy metabolism-related genes (MEMRG) in previous published literatures, 76 IRG and MEMRG (IR & MEMRG) were obtained by taking the intersection of IRG and MEMRG after merging and deduplicating. The limma package in R software was used to screen the differentially expressed genes (DEG) between the tumor group and the control group. Then, immune-related & mitochondrial energy metabolism-related differentially expressed genes (IR&MEMRDEG) were obtained by intersecting with IR & MEMRG. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted on the IR&MEMRDEG through the clusterProfiler package in R software. The STRINGv12.0 online database (https://cn.string-db.org/) was employed to construct a protein interaction network based on IR&MEMRDEG and to identify the top 5 key core genes. Single-sample gene-set enrichment analysis (ssGSEA) was used to determine the relative abundance of immune cell infiltration in all samples, and the immune cell infiltration matrices for both the tumor and the control groups were acquired. The expression differences in infiltration abundance of the immune cells in the tumor group and the control group were analyzing by using the ggplot2 package in R software. The heat map was drawn by utilizing the R software pheatmap package to show self-correlation of immune cells. The correlation between the top 5 key genes in the protein interaction network and immune cells was calculated by using the Spearman algorithm and the R software ggplot2 package.Results:A total of 3 623 DEGs were identified from the TCGA database in both groups, including 1 711 up-regulated genes and 1 912 down-regulated genes. After taking the intersection of DEG and IR&MEMRG, 11 IR&MEMRDEG were obtained including EIF4EBP1, TP53, IDH1, PRCKZ, CD200, GPI, PGM2, PKLR, AK2, ATP4A, and ALDH3B1. GO enrichment analysis results showed that 11 IR&MEMRDEG were mainly enriched in ADP metabolic process, ATP metabolic process, purine nucleoside diphosphate metabolic process, purine ribonucleoside diphosphate metabolic process, and ribonucleoside diphosphate metabolic process at the biological level; in the fibronectin-1 rich granule, secretory granule lumen, cytoplasmic vesiclelumen, vesiclelumen, and nuclear matrix at the cellular component level; in magnesium ion binding, potassium ion binding, and alkali metal ion binding at the molecular functional level. The KEGG enrichment analysis results showed that 11 IR&MEMRDEGs were mainly enriched in glycolysis/gluconeogenesis, carbon metabolism, insulin signaling pathway, pentose phosphate pathway, starch and sucrose metabolism signaling pathways. The protein interaction network analysis from the STRING database revealed that 5 highest scoring core proteins were identified, namely EIF4EBP1, TP53, IDH1, PRKCZ, and AK2.The immune infiltration abundances of 28 immune cells were calculated by using the ssGSEA algorithm. The infiltration abundance of 15 immune cells in the tumor group was higher than that in the control group, and the differences were statistically significant (all P < 0.05). The findings from the immune infiltration analysis indicated a positive correlation among 15 types of immune cells, in which there was a strongest correlation between effector memory CD8 + T cell and myeloid derived suppressor cells. EIF4EBP1, TP53, IDH1, and AK2 exhibited a positive correlation with a large number of immune cells (all P < 0.05), whereas PRKCZ demonstrated a negative correlation with more immune cells (all P < 0.05). Conclusions:PRKCZ, AK2, and EIF4EBP1 have the potential to be the new targets of immunotherapy for gliomas.

Objective To explore a method for assessing the irregular small opacities profusion associated with occupational pneumoconiosis in chest computed tomography (CT). Methods A total of 20 occupational pneumoconiosis patients whose primary manifestation was irregular small opacities on chest digital radiography (DR) were collected as the research subjects using a retrospective study method. Comparative analysis was performed between chest DR and five mm coronal multi-planar reconstruction (MPR) of chest CT images to identify the causes of irregular small opacities. An evaluation method for the profusion of associated images of irregular small opacities in chest CT was established using technique for order preference by similarity to ideal solution-analytic hierarchy process (TOPSIS-AHP), and the results were compared against GBZ 70-2015 Diagnosis of Occupational Pneumoconiosis. Results The abnormal image distribution on the five mm coronal chest CT MPR images of the 20 patients was as follows: three cases of high-density small circular opacities, seven cases of low-density circular small opacities, six cases of diffuse low-density ground-glass opacities (GGO), four cases of reticular opacities, three cases of plate-like GGO, three cases of honeycomb opacities, and four cases of increasing lung texture. The CT values of abnormal images, from high to low were: honeycomb opacities > plate-like GGO > low-density circular small opacities > diffuse low-density GGO (all P<0.05). The consistency test results indicated that the evaluation method for the profusion of associated images of irregular small opacities in chest CT showed high level of agreement with the profusion determination criteria outlined in GBZ 70-2015 Diagnosis of Occupational Pneumoconiosis (Kappa=0.78). Conclusion Irregular small opacities observed on chest DR are formed by the superposition of multiple images of abnormal pulmonary fibrosis in patients with occupational pneumoconiosis. TOPSIS-AHP can be used to establish an evaluation method of the profusion of associated image of irregular small opacity in chest CT.
