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 post-discharge exercise behavior and factors influencing moderate to vigorous intensity physical activity (MVPA) in patients undergoing lung surgery. Methods A total of 2874 patients from the large prospective, observational perioperative lung symptom study cohort (CN-PRO-Lung 3) in the Department of Thoracic Surgery at Sichuan Cancer Hospital between April 7, 2021, and January 31, 2024, were selected as the survey subjects. A survey was conducted using the Investigation of Exercise Behavior after Lung Surgery questionnaire and the International Physical Activity Questionnaire-Short Form (IPAQ-SF) among patients who underwent lung surgery. Binary logistic regression was used to analyze the factors influencing patients’ engagement in MVPA. Results A total of 702 patients were surveyed, including 252 males and 450 females, with an average age of (52.4±10.2) years. Patients with lung cancer accounted for 85.9%. Only 36.0% of the patients had regular exercise habits, while 42.3% did not engage in any physical activity. The three main barriers for postoperative exercise were physical discomfort (pain, coughing, shortness of breath, etc, 54.7%), lack of professional guidance (41.7%), and concerns about the surgical wound (28.9%). The proportions of patients engaging in vigorous, moderate, and low-intensity physical activity were 5.7%, 28.2%, and 66.1%, respectively. Multivariate analysis showed that patients with a personal annual income ≥50000 yuan (OR=1.52, 95%CI 1.01-2.29, P=0.044), high school education or above (OR=1.92, 95%CI 1.33-2.76, P<0.001), and lobectomy (OR=1.44, 95%CI 1.02-2.03, P=0.037) engaged in more MVPA. Conclusion Patients undergoing lung surgery have inadequate physical activity after discharge, particularly lacking in MVPA. Patients with higher income, higher educational levels, and lobectomy are more frequently engaged in MVPA. Measures such as symptom control, providing exercise guidance, and enhancing education on wound care may potentially improve the inadequate physical activity in lung surgery patients after discharge.

BACKGROUND:Deep muscle stimulation has the effects of releasing muscle adhesion,relieving muscle spasm,improving and restoring muscle compliance and elasticity.Electromyographic biofeedback therapy can promote nerve recovery and improve lower limb motor function and gait. OBJECTIVE:To observe the effect of the effect of deep muscle stimulation combined with electromyographic biofeedback therapy on the spasm of the triceps surae and gait changes after stroke by using a digital muscle detector and three-dimensional gait analysis system. METHODS:A total of 72 patients who met the inclusion criteria were selected from the Rehabilitation Department of the First Affiliated Hospital of Guangdong Pharmaceutical University from October 2020 to October 2023.And they were enrolled and randomly divided into two groups(n=36 per group):a control group and a combined group.The control group received routine rehabilitation therapies,electromyographic biofeedback and pseudo deep muscle stimulation,while the combined group received true deep muscle stimulation treatment on the basis of the control group,five times per week,for 4 consecutive weeks.The oscillation frequency and dynamic stiffness of the affected gastrocnemius muscle,active range of motion of the ankle dorsiflexion muscle,electromyographic signal of the tibialis anterior muscle,Fugl-Meyer assessment of the lower limbs,and three-dimensional gait analysis parameters were statistically analyzed before and after treatment in two groups. RESULTS AND CONCLUSION:After treatment,oscillation frequency and dynamic stiffness values of the inner and outer sides of the affected gastrocnemius muscle in both groups of patients were significantly reduced compared with before treatment(P<0.05),and the combined group showed a more significant decrease compared with the control group(P<0.05).The active range of motion of the ankle dorsiflexion muscle,electromyographic signal of the tibialis anterior muscle,and Fugl-Meyer scores after treatment were significantly increased or improved compared with before treatment(P<0.05),while the combined group showed a more significant increase or improvement compared with the control group(P<0.05).In terms of gait parameters,the walking speed,frequency,and stride in both groups of patients were significantly increased compared with before treatment(P<0.05),while the combined group showed a more significant increase compared with the control group(P<0.05).The percentage time of support phase on the healthy side was shortened compared with before treatment(P<0.05),while the combined group showed a more significant decrease compared with the control group(P<0.05).In addition,there was no significant difference between the two groups except for the percentage of healthy side support(P>0.05).To conclude,the combination of deep muscle stimulation and electromyographic biofeedback can effectively alleviate triceps spasm in the short term after stroke,improve ankle dorsiflexion function,enhance lower limb motor function,and improve gait.The treatment effect is significant and worthy of clinical promotion and application.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To construct a questionnaire to measure parents′ behavioral and social drivers (BeSD) in administering rotavirus vaccine to their children, and to test the reliability and validity of the questionnaire.Methods:A questionnaire was constructed to investigate the BeSD of rotavirus vaccination among parents based on the WHO BeSD questionnaire. A survey was conducted among parents of children aged 0-3 years old in vaccination clinics from 15 community health service centers in Nanjing City of Jiangsu Province, Yuhuan and Kaihua Counties of Zhejiang Province, Anqing City of Anhui Province, and Yangpu District of Shanghai City from April to May in 2024. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to analyze the reliability (internal consistency reliability, combination reliability and split half reliability) and validity (structural validity, convergence validity and discriminative validity) of the questionnaire.Results:A total of 850 questionnaires were collected, of which 614 were valid, with an effective response rate of 72.20%. The EFA resulted in the refinement of the rotavirus vaccine BeSD questionnaire from 37 to 35 items (including 24 core items), and suggested a five-factor structure including the perceptions of vaccine, confidence in vaccine, social process of vaccination, motivation for vaccination, and practical problems of vaccination. The cumulative variance contribution rate reached 56.27%. The CFA confirmed an ideal five-factor model fit (GFI=0.82,CFI=0.86,PNFI=0.67,RMSEA=0.07). The AVE of each dimension was greater than 0.50. The AVE square root of each dimension of the questionnaire was greater than its correlation coefficient. The Cronbach′s α coefficient of the total questionnaire was 0.79.Conclusion:The developed BeSD questionnaire of rotavirus vaccine has good reliability and validity, and can be used to measure parents′ behavioral and social factors in administering rotavirus vaccine to their children.

Objective:To evaluate the efficacy of defocus incorporated multiple segments (DIMS) on spherical equivalent (SE) and axial length (AL) in myopic children.Methods:Clinical studies on the progress of DIMS lens intervention in myopia reported in CNKI, Wanfang Data, VIP, China Biomedical Literature Database, PubMed, Embase, Cochrane Library, and Web of Science from the establishment of the database to June 2023 were searched.The experimental group and control group used DIMS lens and single vision lens (SVL) for intervention, respectively.Two researchers independently conducted the literature search, screening and data extraction based on the inclusion and exclusion criteria.Literature quality and risk of bias were evaluated in accordance with the requirements of the Cochrane Manual.Meta-analysis was performed using Revman 5.4 software.Results:A total of 7 clinical studies using DIMS lenses to intervene in the development of myopia were included .Seven studies provided complete SE data for analysis, with sample sizes of 1 164 eyes and 1 140 eyes for the DIMS group and SVL group, respectively.Five studies provided complete AL data for analysis, with sample sizes of 339 eyes and 315 eyes for the DIMS group and SVL group, respectively.There were statistically significant differences in SE and AL between DIMS group and SVL group (SE: WMD=0.40, 95% CI: 0.32-0.47, P<0.001; AL: WMD=-0.14, 95% CI: -0.17--0.11, P<0.001).DIMS lens could effectively delay SE progression and AL growth in myopic patients. Conclusions:DIMS lenses could delay the increase of SE and AL to a certain extent.

Objective To explore the mechanism of Huoxin pill(HXP)in the prevention and treatment of heart failure(HF)based on transcriptomics and network pharmacology.Methods The mice were randomly divided into the normal control group,model control group,positive control group treated with sacubitril/valsartan(60 mg·kg-1),low-dose group treated with HXP(31.2 mg·kg-1),and high-dose group treated with HXP(62.4 mg·kg-1).The model control group and each drug treat-ment group were subcutaneously injected with an equal volume of ISO(5 mg·kg-1)for modeling,while the normal control group was given an equal volume of sterile saline.Six hours later,each drug administration group was gavaged with the corresponding drug for intervention,and the normal control and model control groups were gavaged with an equal volume of sterile water.The modeling and drug administration were continued for 21 days.The cardiac function parameters of the mice were measured using color Doppler ultrasound imaging;ELISA was used to detect the levels of mouse serum cAMP,NT-proBNP,and BNP;HE staining and Masson's trichrome staining were used to evaluate the pathological morphology of cardiac tissue,and the CVF was calculated.Network pharmacology combined with transcriptomics was used to predict potential targets and signaling pathways of HXP in the prevention and treatment of HF,and molecular biology methods were used for validation.Results Compared with the normal control group,the model control group showed an increase in LVESd and LVEDd(P＜0.01),and a decrease in LVEF and LVFS(P＜0.01);BNP,NT-proBNP,and cAMP levels were increased(P＜0.01);myocardial collagen fibers increased and CVF in-creased(P＜0.01).Compared with the model control group,the HXP low-dose group,HXP high-dose group,and positive control groups showed a decrease in LVESd and LVEDd(P＜0.01),and an increase in LVEF and LVFS(P＜0.01);serum levels of BNP,NT-proBNP,and cAMP decreased(P＜0.05);the degree of myocardial fibrosis decreased and CVF decreased(P＜0.01).Network pharmacology combined with transcriptomics predicted 10 key targets for HXP in the prevention and treatment of HF:CACNA1H,SCN10A,FGF12,PVALB,ACAN,LGALS3,SERPINE1,MMP3,GSTM1,VDR.Western blot results showed that the protein activation levels of PKA and CREB in myocardial tissue were increased in the model control group compared with the nor-mal control group(P＜0.01).Compared with the model control group,HXP low-dose group、HXP high-dose group,and positive control groups showed a decrease in the protein activation levels of PKA and CREB in myocardial tissue(P＜0.05).Conclusion HXP has an improvement effect on ISO-induced HF in mice,which may involve numerous targets and the cAMP/PKA signaling pathway.

Objective To identify potential biomarkers for proliferative diabetic retinopathy(PDR)using proteomics and transcriptomics data.Methods In this study,the proteomics dataset(PXD046630)and two transcriptomics datasets(GSE60436 and GSE102485)were derived from the aqueous humor samples and fibrovascular membranes of PDR patients,respectively.Differentially expressed genes(DEGs)were identified via R software,specifically the limma and edgeR pack-ages.The shared DEGs between PXD046630 and GSE60436 were analyzed via protein-protein interaction(PPI),Gene On-tology(GO)enrichment,and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses.The key DEGs were validated in GSE102485 via receiver operating characteristic(ROC)curve analysis.A quantitative polymerase chain reaction(qPCR)assay was used to confirm the mRNA of these candidate biomarkers in human retinal microvascular endothelial cells(HRMECs)cultured in high glucose and low oxygen conditions.Results A total of 59 shared DEGs and 26 hub genes were identified from the PXD046630 and GSE60436 datasets.KEGG analysis revealed that six pathways,inclu-ding extracellular matrix-receptor interaction,proteoglycans in cancer,and complement and coagulation cascades,were enriched in 12 key DEGs.Fibronectin 1(FN1),tissue inhibitor of metalloproteinase 3(TIMP3),complement factor H(CFH),decorin(DCN),and lipoprotein receptor-related protein-2(LRP2)were identified as potential biomarkers on the basis of their AUC values being greater than 0.900(CI≥95％).The mRNA expression levels of FN1,CFH,and LRP2 were significantly increased in HRMECs cultured in high glucose and low oxygen conditions.Conclusion FN1,CFH,and LRP2 are potential biomarkers for PDR,and further studies are needed to explore their roles and therapeutic potential in PDR.

Background: Inhalation-based combination therapy has gained increasing attention for local treatments. However, a key challenge remains in ensuring the sustained pulmonary release of multiple active ingredients, particularly in traditional Chinese medicine (TCM) formulations. Objective: This study investigates a novel PulmoSphere-based inhalable carrier designed for the sustained pulmonary release of multiple active ingredients, using Shuang-Huang-Lian as a model TCM formulation containing three chemical markers. Materials and methods: The carrier was developed using PulmoSphere technology, incorporating phospholipid complexes of the chemical markers and hyaluronic acid (HA) into spray-dried microparticles. The aerodynamic properties, release characteristics, pulmonary distribution, and anti-inflammatory efficacy of different formulations were evaluated in vitro and in mice. Results: The microparticles retained the excellent aerodynamic properties of conventional PulmoSphere particles, with a mass median aerodynamic diameter of approximately 3.1 μm and a fine particle fraction of approximately 55%. Compared to free Shuang-Huang-Lian or phospholipid complex-loaded PulmoSphere particles, the HA-containing particles prolonged the retention of chemical markers in the lung epithelial lining fluid, demonstrating sustained release in vivo. Additionally, the HA-containing formulation enhanced the exposure of the three chemical markers to immune cells and lung tissues, leading to improved and prolonged anti-inflammatory effects, even at decreased doses. Conclusion: This novel inhalable particle system represents a promising approach for sustained pulmonary co-delivery of multiple active ingredients, offering enhanced and extended local therapeutic efficacy.

Objective To comparatively evaluate the diagnostic value of metagenomic next-generation sequencing(mNGS)versus conventional microbial culture in spinal infections.Methods A cross-section design was conducted on 82 consecutive patients with suspected spinal infections treated between February 2022 and January 2024 at Jiangbei Branch of First Affiliated Hospital of Army Medical University(Third Military Medical University).Microbiological culture,histopathological examination,and mNGS results from infected specimens were analyzed.Clinical diagnosis,primarily based on clinical manifestations,laboratory tests and radiologic features combined with medical history,was defined as the gold standard,and then the diagnostic performance,including sensitivity and specificity,were compared between mNGS and microbial culture.Results Among the 82 patients,definitive microbiological evidence was identified in 70 cases,and mNGS demonstrated a significantly higher detection rate than microbial culture(64 vs 36 cases,78.05％vs 43.9％,P<0.05).mNGS also obtained obviously higher sensitivity,accuracy,and negative predictive value(NPV),and notably lower positive predictive value(PPV)when compared to conventional microbial culture(all P<0.05).When stratified by infection type,mNGS obtained significantly higher sensitivity and accuracy compared to microbial culture in tuberculous spinal infections(P<0.05).For non-tuberculous spinal infections,mNGS also showed superior sensitivity to microbial culture(P<0.05).Conclusion In patients with spinal infections,mNGS demonstrates a significantly higher pathogen detection rate than conventional microbial culture.This technique can provide early and broad-spectrum pathogenic microbiological evidence for spinal infection.
