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 explore the clinical characteristics of autoimmune encephalitis (AE) and the related factors of social frailty. Methods A total of 412 patients with AE admitted to the hospital between January 2020 and August 2025 were collected as research subjects. According to the occurrence status of social frailty, the above patients were classified into social frailty group (n=166) and control group (n=246). The clinical data of patients were analyzed, Multivariate logistic regression analysis was used to analyze the related factors of social frailty in patients with AE.. Results Among the 412 patients, 166 cases (40.29%) had social frailty and 246 cases (59.71%) did not have social frailty. The proportions of age≥40 years old, language disorder, epileptic seizure, acute onset and abnormal cranial magnetic resonance imaging (MRI) in the social frailty group were higher than those in the control group (Multivariate logistic regression analysis was used to analyze the related factors of social frailty in patients with AE.P<0.05). Age≥40 years old, language disorder, acute onset, Abnormal cranial magnetic resonance imaging is a related factor for the occurrence of social frailty in patients with AE (P<0.05). The area under the curve of the logistic regression model for prediction was 0.851, suggesting that the model had good predictive value. Conclusion Age, language disorder, epileptic seizure, acute onset and cranial MRI abnormality are important risk factors of social frailty in patients with AE. The prediction model based on these factors exhibits good clinical application value.

Treatment resistance, recurrence, and metastasis of breast cancer remain critical issues affecting long-term patient survival. Chronic psychological stress may act as a host biological driver of breast cancer treatment resistance rather than a mere comorbidity. Through the sustained activation of the sympathetic nervous system and the hypothalamic-pituitary-adrenal axis, also referred to as the "brain-tumor axis", stress signaling reshapes inflammatory, immune, and metabolic networks within the tumor microenvironment and thereby influences chemotherapy, endocrine therapy, anti-HER2 therapy, immunotherapy, and radiotherapy. Current evidence indicates that the key pathways with translational potential are mainly the β-adrenergic axis and the glucocorticoid receptor (GR) pathway. The former is more involved in amplifying inflammatory responses, promoting immunosuppression and metastasis, whereas the latter is closely associated with anti-apoptosis, maintenance of tumor stemness, and reprogramming of estrogen receptor function. This review focuses on the discrepancies in evidence regarding these pathways between population-based studies and preclinical models, and discusses clinically operable non-pharmacologic interventions such as cognitive behavioral stress management, nurse navigation and treatment adherence support, and exercise interventions during the neoadjuvant phase. Although high-level evidence for direct survival benefit remains limited, these interventions have shown favorable effects on cortisol levels, depressive symptoms, quality of life, adherence, relative dose intensity, and some biology-related intermediate endpoints, making them valuable complementary approaches in comprehensive breast cancer management.

OBJECTIVE To investigate the mechanism of Yangfei tongluo formula in delaying airway remodeling in post-infectious bronchiolitis obliterans （PIBO） model rats.METHODS Forty-eight 2-week-old SPF male SD rats were randomly divided into control group （Control group）， PIBO model group （Model group）， Prednisone Acetate tablets+Azithromycin tablets group [positive control group， Prednisone Acetate tablets 0.006 3 g/（kg·d）+Azithromycin tablets 0.031 5 g/（kg·d）]， and high-， medium-， and low-dose Yangfei tongluo formula groups [42.42， 21.21， 10.60 g/（kg·d）]. The PIBO rat model was established by intratracheal instillation of diacetyl. After modeling， rats in each group were administered corresponding drug solution or distilled water by gavage once daily for 21 consecutive days. Hematoxylin-eosin staining was used to evaluate the pathological changes of lung tissue， and Masson staining was used to assess the degree of pulmonary fibrosis. Western blot and real-time quantitative PCR were performed to detect the protein and mRNA expression levels of epithelial-mesenchymal transition （EMT）-related markers [E-cadherin， N-cadherin， α -smooth muscle actin （ α -SMA）， Vimentin] and transcription factors [snail homolog 1（Drosophila）-like 1 protein （Snail1）， zinc finger E-box-binding homeobox protein 1 （ZEB1）， Twist-related protein 1 （Twist1）] in lung tissue. ELISA was used to detect the levels of transforming growth factor-β 1 （TGF-β 1 ） and vascular endothelial growth factor （VEGF） in blood and bronchoalveolar lavage fluid.RESULTS Compared with the Control group， the lung tissues of rats in the Model group showed extensive destruction of alveolar structure and massive inflammatory cell infiltration in the interstitium. The protein and mRNA expression levels of E-cadherin were significantly decreased， while the protein and mRNA expression levels of N-cadherin， Vimentin， α -SMA， Snail1， ZEB1， and Twist1， as well as the collagen-positive area and the levels of TGF-β 1 and VEGF， were significantly increased （ P ＜0.05）. Compared with the Model group， the pathological injury of lung tissue in each administration group was significantly improved， and the above indicators （except collagen-positive area） were significantly reversed （ P ＜0.05）.CONCLUSIONS Yangfei tongluo formula may delay airway remodeling in PIBO by regulating the TGF-β 1 /VEGF-mediated signaling network and inhibiting the activation of EMT-related transcription factors， thereby blocking the EMT process.

Diabetes, hyperlipidemia, and hyperuricemia have emerged as global chronic metabolic disorders posing significant public health challenges. Edible medicinal plants demonstrate multitarget regulatory effects and favorable safety profiles in the management of chronic metabolic diseases, owing to their bioactive compounds and nutritional synergy. Radix Astragali (RA), a traditional Chinese medicine with medicine–food homology, has a long history of application in China. Based on a review of relevant literature, this article discusses the historical background, modern research, therapeutic functions, and mechanisms of RA in the treatment of chronic metabolic diseases. Modern studies have shown that RA contains a variety of bioactive components and demonstrates efficacy in managing diabetes, hyperlipidemia, and hyperuricemia. Its mechanisms of action involve modulation of the insulin signaling pathway, regulation of lipid metabolism-related enzyme activity, promotion of uric acid excretion, and other processes. Notably, RA exhibits certain common therapeutic effects across hyperglycemia, hyperlipidemia, and hyperuricemia. Through modulation of the gut microbiota and inhibition of inflammatory pathways, RA exerts synergistic, multitarget effects that improve metabolic disorders associated with chronic metabolic diseases.

Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

OBJECTIVES: Stigma is common among community-dwelling patients with schizophrenia and has a profound negative impact on both psychiatric symptoms and quality of life. This study aims to explore the association between stigma and quality of life in this population and to examine the multiple mediating roles of anxiety and depression symptoms. METHODS: The multi-stage stratified cluster random sampling method was used to select the community-dwelling patients with schizophrenics in Chengdu, Sichuan Province, China. The questionnaire included general demographic characteristics, stigma question, the Generalized Anxiety Disorder-7 (GAD-7) scale, the Patient Health Questionnaire-9 (PHQ-9), and the 12-item Short Form Health Survey (SF-12). The SF-12 was used to measure quality of life, including physical health and mental health dimensions. A multiple mediation model was used to analyse the mediating effects of anxiety and depression symptoms together between stigma and quality of life. RESULTS: A total of 1 087 community patients with schizophrenia were included with a mean age of 50.68±12.73 years; 525 (48.30%) were male. Stigma was reported by 543 patients (49.95%). Anxiety symptoms were present in 292 patients (26.86%), and depression symptoms in 407 patients (37.44%). The physical health quality of life score was 72.01 ± 20.99, and the mental health quality of life score was 71.68 ± 19.38. Multiple mediation analysis showed that stigma directly affected quality of life, and also indirectly affected quality of life through anxiety and depression symptoms. Anxiety and depression jointly mediated 42.26% of the total effect of stigma on physical health quality of life and 47.51% on mental health quality of life. CONCLUSIONS Reducing stigma and preventing anxiety and depression symptoms in community-dwelling patients with schizophrenia can effectively improve their quality of life and support reintegration into society.

OBJECTIVES: To investigate the therapeutic effect of the natural compound niranthin on Crohn's disease-like colitis in mice and explore the underlying molecular mechanisms. METHODS: In a mouse model of colitis induced by 2,4,6-trinitro-benzenesulfonic acid (TNBS), the therapeutic effect of niranthin was evaluated by observing the changes in body weight, disease activity index (DAI), and colon length of the mice. The levels of inflammatory cytokines (IL-6, IL-1β, TNF-α, IL-17A and IL-10) in the intestinal mucosal tissue were detected using ELISA and quantitative real-time PCR (qRT-PCR). TUNEL staining and Western blotting were used to assess intestinal epithelial cell apoptosis and the expressions of Bcl-2 and Bax. The expression levels of tight junction proteins (ZO-1 and claudin-1) and the activation of the p38/JNK signaling pathway were investigated using Western blotting, and diprovocim intervention experiments were conducted to explore the molecular regulatory mechanism of niranthin. RESULTS: Niranthin treatment significantly increased body weight of TNBS-treated mice, lowered the DAI and histological inflammation scores, and increased colon length of the mice. The niranthin-treated mouse models showed obviously reduced protein and mRNA levels of IL-6, IL-1β, IL-17A, and TNF-α and upregulated expression of IL-10 in the colon tissue. TUNEL staining and Western blotting demonstrated that niranthin significantly inhibited intestinal epithelial cell apoptosis and activated the anti-apoptotic pathway in the mouse models. Niranthin treatment obviously upregulated the expression levels of ZO-1 and claudin-1 and downregulated the phosphorylation levels of p38 and JNK in the colon tissues of the mice. Diprovocim intervention obviously attenuated the inactivation of the p38/JNK signaling pathway induced by niranthin in the mouse models. CONCLUSIONS Niranthin ameliorates TNBS-induced Crohn's disease-like colitis in mice by inhibiting intestinal epithelial cell apoptosis and protecting the integrity of the intestinal barrier via regulating the activation of the p38/JNK signaling pathway.
