With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

Objective To investigate the association of serum total testosterone(TT),free testosterone(FT),sex hormone-binding globulin(SHBG),and estradiol(E_2)with all-cause mortality rate(AMR)in males and to evaluate their predictive value. Methods Based on data from the National Health and Nutrition Examination Survey(NHANES)cycles(1999—2004 and 2013—2016),the relationships between different sex hormones and AMR was analyzed with Cox proportional hazards regression models. The dose-response relationships between different sex hormones and male AMR were assessed with restricted cubic splines(RCS). The predictive performances of different sex hormones for male AMR were compared with receiver operating characteristic(ROC)curves and the area under the curve(AUC). The survival differences across varying sex hormone levels were evaluated with Kaplan-Meier survival curves and log-rank tests. Results This study involved 3632 adult male participants with a median follow-up of 6.5 years,during which 320 AMR occurred(8.8%). Cox univariate analysis indicated that TT,FT and SHBG were risk factors for AMR(P＜0.001). Cox multivariate analysis revealed that FT and SHBG were independent risk factors for AMR(FT:HR=0.90,95%CI:0.86-0.94; SHBG:HR=1.01,95%CI:1.01-1.02). RCS revealed a U-shaped nonlinear relationship between TT,FT and AMR(P＜0.001); SHBG showed a positive dose-response relationship with AMR(P＜0.001). The AUCs of FT predicting the 5-year,10-year,and 15-year AMR were 0.78(95%CI:0.73-0.82),0.80(95%CI:0.76-0.84),and 0.84(95%CI: 0.80-0.88),respectively,significantly outperforming other indicators. Subgroup analysis revealed that FT was negatively correlated with male AMR,but this association was modulated by age,race,smoking status and diabetes status(P_(interaction)＜0.05). Kaplan-Meier survival analysis showed that different levels of TT and FT(Q1-Q4)were significantly positively correlated with survival rate(P＜0.001),while different levels of SHBG were significantly negatively correlated with survival rate,with patients in the Q4 group having the highest risk of death(P＜0.001). Conclusion Based on US NHANES,studies have shown that the FT and SHBG are independent risk factors for male AMR,and FT demonstrates greater predictive value for male AMR than TT.

With the accelerating aging of the population, the proportion of elderly patients with lung cancer continues to rise, presenting multiple challenges to perioperative management. This paper systematically reviews the clinical characteristics of elderly lung cancer patients. Based on the comprehensive geriatric assessment, it proposes incorporating seven major geriatric syndromes—frailty, delirium, sarcopenia, cognitive impairment, malnutrition, dysphagia, and mood disorders—into the core evaluation system. By integrating multimorbidity management with complication prevention and control, an integrated "geriatric syndrome-multimorbidity-complication" perioperative management model is constructed. Furthermore, this paper outlines stratified intervention strategies for geriatric syndromes, a "five-step" workflow for comorbidity management, and a comprehensive intervention pathway for complications across the preoperative, intraoperative, and postoperative phases. Multidisciplinary team (MDT) collaboration serves as the core mechanism to achieve individualized comprehensive treatment. This paper aims to provide a novel perioperative comprehensive treatment model for elderly lung cancer patients, which is centered on geriatrics, supported by multidisciplinary collaboration, and guided by precision medicine.

ObjectiveTo explore the long-term dynamic trajectories of fasting blood glucose （FBG） and insulin resistance （IR） in patients with type 2 diabetes mellitus （T2DM） and their influencing factors. MethodsThis retrospective cohort study included 1 896 T2DM patients registered at Tongren Hospital from May 2020 to May 2025. Based on longitudinal follow-up data of FBG and fasting insulin， joint latent class mixed models （JLMM） were applied to identify FBG-IR trajectories. Univariate and multinomial logistic regression was used to examine demographic characteristics， lifestyle， and clinical determinants of trajectory type. ResultsFour distinct FBG-IR trajectories were identified： stable FBG-IR （9.76%）， rising FBG-stable IR （5.01%）， stable FBG-elevated IR （75.90%）， and elevated FBG-IR （9.34%）. Compared with the stable FBG-IR group， age ≥60 years was protective against the elevated FBG-stable IR trajectory （OR=0.55， 95%CI：0.33-0.92， P=0.023）. Highereducation increased the risk of stable FBG-elevated IR （OR=1.40， 95%CI：1.01-1.94， P=0.046）. Abnormal blood pressure was associated with lower risks of stable FBG-elevated IR （OR=0.66， 95%CI：0.48-0.92， P=0.013） and elevated FBG-IR （OR=0.48， 95%CI：0.31-0.74， P=0.001）. Non-drinkers were less likely to belong to the stable FBG-elevated IR trajectory （OR=0.39， 95%CI：0.16-0.95， P=0.038）. ConclusionsThe evolution trajectory of FBG and IR in T2DM patients shows significant heterogeneity. The majority of patients have a deterioration of IR first. Age， education level， blood pressure， and alcohol consumption are the main influencing factors. Joint assessment of FBG and IR is helpful for early identification of high-risk individuals and guiding individualized intervention.

Objective To investigate the effect and mechanism of circular RNA_0009910(circ_0009910)on the proliferation and apoptosis of non-small cell lung cancer cells.Methods A549 cells were randomly divided into groups and transfected as follows:si-NC group,si-circ_0009910 group,miR-NC group,miR-34a-5p group,si-circ_0009910+anti-miR-NC group,and si-circ_0009910+anti-miR-34a-5p group.After successful transfec-tion,cell proliferation was measured using the CCK-8 assay.Dual-luciferase reporter assays were used to vali-date the target gene of circ_0009910.Apoptosis of A549 cells was analyzed by flow cytometry.Protein expres-sion levels of B-cell lymphoma-2(Bcl-2),transmembrane receptor protein 1(Notch1),cell proliferation-asso-ciated nuclear antigen(Ki-67),Bcl-2-associated X protein(Bax),and cysteine aspartic acid protease-3(Caspase-3)were detected by Western blot.Cells from each group were subcutaneously injected into the abdo-mens of male nude mice to establish xenograft models.Tumor volume,tumor weight,and protein expression in tumor tissues were measured.Results Compared with the si-NC group,the si-circ_0009910 group showed significantly reduced A549 cell proliferation,increased apoptosis,decreased expression of Ki-67,Notch1,and Bcl-2,and increased expression of Bax and Caspase-3(P＜0.05).Compared with the miR-NC group,the miR-34a-5p group exhibited significantly reduced luciferase activity after transfection with wild-type circ_0009910(P＜0.05).The si-circ_0009910 group showed upregulated miR-34a-5p expression compared to the si-NC group.The miR-34a-5p group demonstrated weaker proliferation,higher apoptosis,downregulated Bcl-2,Notch1,and Ki-67,and upregulated Bax and Caspase-3 compared to the miR-NC group(P＜0.05).Compared with the si-circ_0009910+anti-miR-NC group,the si-circ_0009910+anti-miR-34a-5p group exhibited en-hanced proliferation,reduced apoptosis,upregulated Bcl-2,Notch1,and Ki-67,and downregulated Bax and Caspase-3(P＜0.05).In vivo,the si-circ_0009910 and miR-34a-5p groups showed smaller tumor volumes and weights,downregulated Notch1,Ki-67,and Bcl-2,and upregulated Bax and Caspase-3 in tumor tissues com-pared to their respective control groups(P＜0.05).Conclusion Low expression of circ_0009910 inhibits A549 cell proliferation and promotes apoptosis,potentially via the miR-34a-5p/Notch1 signaling pathway.

Objective To explore the effects of esophageal vocalization training based on health empowerment model on self-efficiency,self-management ability and vocal function in patients with laryngeal cancer after total laryngectomy.Methods A total of 86 patients with laryngeal cancer who underwent total laryngectomy in The Second Affiliated Hospital of Naval Medical University from January 2023 to June 2024 were selected as the research subjects.The patients returned to the hospital to receive esophageal vocalization training 2 months after surgery.According to the random number table method,patients were assigned to control group(43 cases,receiving routine care)or observation group(43 cases,receiving routine care and nursing based on health empowerment).The training continued for 3 months.The general self efficacy scale(GSES)score,exercise of self-care agency scale(ESCA),voice handicap index(VHI)score,and training compliance were compared between the two groups before and after nursing care.Results After 3 months of vocal training,the GSES and ESCA scores of both groups increased,while VHI score decreased.The observation group had higher GSES and ESCA scores and lower VHI score than the control group(P<0.05).The overall compliance rate of the observation group was higher than that of the control group(P<0.05).Conclusion The esophageal vocalization training based on health empowerment can improve self-efficacy,self-management ability,training compliance,and vocal function in patients with laryngeal cancer after total laryngectomy.

Results There were 4 males and 1 female with an average age of (46.2±18.6) years. This study included 1 patient of aortic arch aneurysm and 4 patients of acute non-A non-B aortic dissection. The success rate of surgical technique was 100.0%. The operative time was (132.3±45.1) min, the immediate postoperative isolation of lesions was satisfactory, and there were no adverse events and death in perioperative period. The follow-up time was 12-15 months. During the follow-up period, all patients survived without stent displacement, type Ⅰa endoleak, parallel stent stenosis and occlusion, or re-operation. Conclusion The short and medium term results of single branched stents combined with parallel stents in total endovascular repair of aortic arch diseases requiring Z1 anchoring is satisfactory.

Objective:To investigate whether herb cake-insulated moxibustion affects the expression of cholesterol metabolism-related protein 3-hydroxy-3-methylglutaryl coenzyme A reductase(HMGR)and inhibits the development of atherosclerosis by regulating the exosomal miR-223 expression.Methods:Thirty-six male New Zealand rabbits were randomly assigned to a normal group,a model group,and an herb cake-insulated moxibustion group,with 12 rabbits in each group.The model and the herb cake-insulated moxibustion groups were fed a high-fat diet for 8 weeks to induce an atherosclerosis model.Following successful modeling,the herb cake-insulated moxibustion group was subjected to bundling and herb cake-insulated moxibustion intervention,while the other two groups were subjected only to bundling without moxibustion.After 8 weeks of intervention,hematoxylin-eosin(HE)staining was used to observe aortic morphology;the serum levels of total cholesterol(TC),triglyceride(TG),and low-density lipoprotein cholesterol(LDL-C)were detected using an automatic biochemical analyzer in each group.Exosome morphology was observed using the transmission electron microscope;Western blotting(WB)was used to detect the protein levels of serum exosomal CD63 and CD9 markers,as well as liver HMGR;additionally,real-time fluorescence quantitative polymerase chain reaction was used to quantify serum exosomal miR-223.Results:HE staining showed thickened aortic intima,lipid infiltration,foam cell aggregation,and structural damage to the arterial wall in the model group.Meanwhile,after modeling,the serum levels of LDL-C,TC,and TG increased significantly in the model and herb cake-insulated moxibustion groups compared to the normal group(P<0.05),suggesting successful atherosclerosis rabbit model preparation.The serum exosomes of rabbits in the model group exhibited a saucer-like or semi-concave spherical shape with diameters of 120-150 nm.WB detection results showed positive expression of the exosomal markers CD63 and CD9.After 8 weeks of intervention,the miR-223 level in the model group was significantly lower than that in the normal group(P<0.01).In contrast,the herb cake-insulated moxibustion group demonstrated significantly reduced serum levels of TC,TG,and LDL-C(P<0.05),increased miR-223 expression(P<0.01),and decreased relative liver HMGR protein expression(P<0.05)compared to the model group.Conclusion:Herb cake-insulated moxibustion may alleviate the progression of atherosclerosis by up-regulating exosomal miR-223 expression and down-regulating HMGR protein expression,thereby inhibiting cholesterol anabolic metabolism.

Objective To observe the value of artificial intelligence iterative reconstruction(AIIR)for low-dose chest CT images of infants with congenital heart disease.Methods Totally 262 infants with congenital heart disease who would undergo chest CT scanning were prospectively enrolled and randomly divided into low-dose group(n=142)and conventional dose group(n=120).Chest CT scanning with tube voltage of 80 kVp and tube current of 10 mAs was performed in low-dose group,and hybrid iterative reconstruction(HIR,group A)and AIIR(group B)were used to reconstruct images,respectively.In conventional dose group,chest CT scanning with tube voltage of 80 kVp and tube current of 100 mAs was performed,and HIR was used to reconstruct images(group C).Then subjective and objective evaluation on image quality were performed,the results were compared among 3 groups,and the value of AIIR was analyzed.Results Significant differences of image quality and clarity of displaying structures were found among 3 groups(all P＜0.001).Among them,except for the clarity of interlobar fissure,no significant difference of subjective scores was found between low-dose AIIR images and conventional dose HIR images(all corrected P＞0.05),while subjective scores of low-dose HIR images were all lower than those of low-dose AIIR images and conventional dose HIR images(all corrected P＜0.05).Significant differences of standard deviation(SD),signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)were found among 3 groups(all P＜0.001)and between each 2 groups(all corrected P＜0.05).The effective dose of low-dose group and conventional dose group was 0.09(0.08,0.10)and 0.85(0.75,1.03)mSv,respectively,and the former was lower than the latter(Z=-13.942,P＜0.001).Conclusion Using AIIR could obtain low-dose chest CT images of infants with quality comparable to conventional chest CT images.
