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 establish a quality and safety evaluation index system for the daytime chemotherapy in the Day Medical Management Quality Control Center of Fujian Province, providing references for objectively evaluating the quality of day chemotherapy.Methods:From December 2023 to August 2024, this study screened the initial indexes of the quality and safety evaluation index system for daytime chemotherapy through literature search and expert discussions. An index system and its weights were determined by using two rounds of Delphi method and precedence chart method. The quality of daytime chemotherapy services in 8 hospitals was evaluated by using a thousand point scale checklist based on this index system.Results:The expert motivation of both rounds of Delphi method was 100%, and the expert authority coefficient was 0.92. The quality and safety evaluation index system for daytime chemotherapy included 3 first-level indicators, 13 second-level indicators, and 54 third-level indicators; Among them, the weights of the first-level indicator included structure quality, process quality, and result quality were 0.334, 0.556, and 0.110, respectively. The quality and safety scores of daytime chemotherapy in 8 hospitals ranged from 812 to 980 points, with an average of 933 points.Conclusions:The quality and safety evaluation index system for daytime chemotherapy could objectively and comprehensively evaluate the quality and safety of hospital daytime chemotherapy.

In this work,a fluorescent probe PIN was synthesized using indole-3-carbohydrazide and pyrenecarboxaldehyde as raw materials.PIN showed weak fluorescence emission in aqueous solution with acetonitrile volume fraction of 70％.However,when Cu2+was added to this aqueous solution of PIN,a new fluorescence emission peak appeared at 495 nm,and the intensity of this peak gradually increased with the increase of concentration of Cu2+,and also caused a significant change in the fluorescence color of the solution.In contrast,the addition of 15 kinds of other common metal ions did not cause such change.The detection limit of PIN for Cu2+was 78.7 nmol/L,which was much lower than the maximum permitting level of Cu2+in drinking water in hygienic standard for drinking water in China.Therefore,PIN was a highly selective and sensitive fluorescence-enhanced probe for Cu2+.Meanwhile,the addition of Cu2+could also cause a new absorption peak at 440 nm in the ultraviolet-visible absorption spectrum of the aqueous solution of PIN,and meanwhile the colorless PIN solution changed into yellow,exhibiting the performance of PIN as a colorimetric probe for Cu2+.By fitting with the Levenberg-Marquardt algorithm equation,the binding ratio of PIN to Cu2+was 2:1,and the binding constant was 3.42×1012 L2/mol2.In addition,the binding mode of PIN with Cu2+was explored by using proton nuclear magnetic resonance(1H NMR)titration experiments and density functional theory simulations.The results showed that the addition of Cu2+could cause the aggregation of PIN molecules to form excimers,thus showing highly selective recognition.Finally,PIN was made into a simple test strip,which could achieve rapid and convenient fluorescence detection of Cu2+in actual water samples.

BACKGROUND:In the occurrence and development of demyelinating diseases of the central nervous system,neuroinflammation caused by microglia is the main pathological feature,so inhibiting the inflammatory response is very important to alleviate demyelination.Hydroxysafflor yellow A can protect the blood-brain barrier,inhibit neuronal apoptosis,and improve neurological function.OBJECTIVE:To explore the mechanism of hydroxysafflor yellow A inhibiting bicyclohexanone oxalyl dihydrazone-induced demyelination in mice.METHODS:(1)In vivo:Thirty healthy male C57BL/6 mice were randomly divided into three groups:normal group,cuprizone group,and hydroxysafflor yellow A group.The mice in the cuprizone group and the hydroxysafflor yellow A group were fed with 0.2％cuprizone diet for 6 weeks to establish mouse models of demyelination.The mice in the normal group were fed with normal diet.At the end of the 4th week,the mice in the hydroxysafflor yellow A group were intraperitoneally injected with hydroxysafflor yellow A 20 mg/kg per day.The mice in the normal and cuprizone groups were intraperitoneally injected with normal saline for 2 weeks.The behavioral changes of mice were evaluated by open field test and elevated plus maze test.The loss of myelin sheath in corpus callosum was detected by black gold staining,myelin basic protein and degraded myelin basic protein immunofluorescence staining.The activation of microglia and the expression of inflammatory factors were detected by I ba-1 immunofluorescence staining and ELISA,respectively.The protein expression levels of Toll-like receptor 4,myeloid differentiation factor 88,and nuclear factor κB p65 in the brain of mice in each group were detected by western blot assay.(2)In vitro experiment:The inflammation model of BV2 microglia was established by lipopolysaccharide induction.BV2 cells were divided into normal group,lipopolysaccharide group(1 μg/mL),and lipopolysaccharide(1 μg/mL)+hydroxysafflor yellow A(25 μmol/L)group.The expression levels of tumor necrosis factor α and interleukin 6 in the supernatant were detected by ELISA.RESULTS AND CONCLUSION:(1)Compared with the normal group,the mice in the cuprizone group had severe anxiety,abnormal autonomic movement ability,and a large amount of myelin sheath loss in the corpus callosum.The average fluorescence intensity of myelin basic protein was significantly reduced,and the average fluorescence intensity of degraded myelin basic protein was significantly increased.The number of lba1+microglia increased,the contents of interleukin 1β,tumor necrosis factor α,and interleukin 6 in the brain increased,and the protein expression levels of Toll-like receptor 4,myeloid differentiation factor 88,and nuclear factor κB p65 increased significantly.The above symptoms and indexes of mice were reversed after hydroxysafflor yellow A treatment.(2)Hydroxysafflor yellow A significantly inhibited the expression of inflammatory factors such as tumor necrosis factor α,and interleukin 6 induced by lipopolysaccharide in BV2 microglia.(3)The above results demonstrate that hydroxysafflor yellow A can significantly improve cuprizone-induced demyelination in mice.The mechanism of action is related to the inhibition of microglial activation-mediated inflammatory response through the Toll-like receptor 4/myeloid differentiation factor 88/nuclear factor κB p65 signaling pathway.

BACKGROUND:Hepatocyte-like cells induced by mesenchymal stem cells are promising seed cells for liver regeneration or liver tissue engineering.The efficiency of traditional two-dimensional culture for hepatocyte induction is low,and more and more research is focused on three-dimensional culture for inducing hepatocyte differentiation.OBJECTIVE:To summarize three-dimensional culture models for the hepatic induction of mesenchymal stem cells,focus on research progress on the epigenetic regulation mechanisms of mesenchymal stem cell hepatogenic differentiation,providing a theoretical basis for improving the differentiation efficiency of mesenchymal stem cells.METHODS:Relevant articles in the PubMed and other databases such as CNKI were searched,using Chinese and English search terms"mesenchymal stem cell,3D culture,hepatogenic differentiation,hepatocyte-like cells,epigenetics."Additionally,the literature tracing method was employed to find some of the literature for a comprehensive review and analysis.RESULTS AND CONCLUSION:(1)Common three-dimensional culture models for the hepatogenic differentiation of mesenchymal stem cells currently include spheroids,biological scaffolds,bioprinting,and microfluidic chips.Each of these models has its own advantages and disadvantages in the process of inducing hepatogenic differentiation.(2)During the differentiation of mesenchymal stem cells into hepatocyte-like cells,epigenetic regulation plays a key role,primarily involving histone modification,DNA methylation,and the regulation of non-coding RNAs.(3)Under three-dimensional culture conditions,epigenetic modifications,especially histone acetylation,play an important role in promoting the hepatogenic differentiation of mesenchymal stem cells.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective To study the correlation between the serum ferritin level and the pathological classification,tumor stage,PD-L1 expression,disease control rate(DCR),and survival period of patients with lung cancer.Methods A total of 85 patients with lung cancer admitted to our hospital from February 2020 to February 2021 were selected as the research subjects.All patients received immunotherapy,and the serum ferritin levels of patients before and after immunotherapy were detected.Meanwhile,according to the difference in serum ferritin levels before and after immunotherapy,the patients were divided into the increased group(31 cases)and the decreased group(54 cases).The correlation between the serum ferritin level and the pathological classification,tumor stage and PD-L1 expression level of patients was analyzed,and the DCRs and survival periods of patients with serum ferritin level≥300 ng/mL and<300 ng/mL before treatment were compared,as well as the increased group and the decreased group.The survival curve of patients in each group was analyzed by the Kaplan-Meier.Results Patients with tumor stage Ⅰ to Ⅲ showed significantly lower serum ferritin levels than patients with tumor stage Ⅳ(P<0.05).The DCR,3-year survival rate and progression-free survival(PFS)of patients with serum ferritin level≥300 ng/mL were significantly lower/shorter than those of patients with serum ferritin level<300 ng/mL(P<0.05).The DCR,3-year survival rate and PFS of patients in the increased group were significantly lower/shorter than those in the decreased group(P<0.05).Conclusion The increased serum ferritin level in lung cancer patients before treatment and the further increase after treatment are significantly associated with the reduced efficacy of immunotherapy and the shortened survival period.The combination of baseline serum ferritin levels before treatment and dynamic changes after treatment may serve as a clinical biomarker panel for predicting immunotherapy outcomes.
