ObjectiveTo investigate the association of physical activity and balance ability with disability, and to further examine the mediating role of balance ability in the relationship between physical activity and disability. MethodsBased on data from 2021 to 2023 National Health and Nutrition Examination Survey (NHANES) cycle, a multivariable Logistic regression model was constructed to evaluate the independent association of physical activity and balance ability with disability, with covariates adjusted in four steps. An interaction model was further developed to assess the multiplicative interaction between physical activity and balance ability. Mediation analysis was performed using the Baron and Kenny three-step approach to examine the mediating role of balance ability, and the proportion of the mediation effect was calculated. The significance of the mediation effect was assessed using the Delta method, and robustness was verified through the Bootstrap method with a fixed random seed. Multiple sensitivity analyses were conducted to ensure the stability of the results. ResultsA total of 3 902 participants were included, with a prevalence of disability of 17.7%. Multivariable regression analysis showed that, after adjusting for all covariates, both light-intensity physical activity (LIPA) (OR = 0.489, 95%CI 0.380 to 0.629, P < 0.001) and high-intensity physical activity (HIPA) (OR = 0.493, 95%CI 0.371 to 0.656, P < 0.001) were significantly associated with a reduced risk of disability, whereas impaired balance ability was significantly associated with an increased risk (OR = 1.579, 95%CI 1.266 to 1.970, P < 0.001). The interaction effect analysis showed that the interaction between physical activity and balance ability were not significant (P > 0.05), however, the main effect of LIPA remained robust (β = -0.597, SE = 0.221, OR = 0.550, P = 0.007), while impaired balance ability was significantly associated with an increased risk of disability (β = 0.577, SE = 0.231, OR = 1.780, P = 0.012). The mediation analysis further indicated that balance ability played a robust mediating role in the association between LIPA and disability, with a mediation proportion of 21.1%. The indirect effect (a × b) was statistically significant (P < 0.001), and the 95% confidence intervals derived from the bootstrap method did not include zero. ConclusionPhysical activity and balance ability are significantly associated with disability, and balance ability may mediate the relationship between physical activity and disability, highlighting its potential value in disability risk assessment and intervention strategies.

Objective To systematically review the studies on predictive models for delayed graft function (DGF) after kidney transplantation. Methods Databases including China Biology Medicine Database, China National Knowledge Infrastructure, Wanfang Database, VIP Database, PubMed, Web of Science and CINAHL were searched to collect studies on predictive models for DGF after kidney transplantation published from the establishment of each database to June 29, 2025. Two researchers screened the literatures according to the inclusion and exclusion criteria, evaluated the quality of the literatures using the prediction model risk of bias assessment tool (PROBAST), and conducted a meta-analysis of the common predictors of the models using R software. Results A total of 12 literatures were included, involving 14 predictive models with sample sizes ranging from 103 to 24 653 cases. Donor serum creatinine level, cold ischemia time, donor age and donor body mass index were the top four common predictors. All the predictive models were at high risk of bias and low in applicability. The results of meta-analysis showed that abnormal donor body mass index, advanced donor age, prolonged cold ischemia time and elevated donor serum creatinine level were all associated with an increased risk of DGF after transplantation (all P<0.01), but there was high heterogeneity among the studies. Fixed-effect model and random-effect model were used to re-pool the effect sizes separately. The results indicated that the fixed-effect model and random-effect model had good consistency in terms of donor body mass index, donor age and cold ischemia time, while there was a significant difference in the effect sizes of the two models for donor serum creatinine level. Conclusions The predictive models for DGF risk after kidney transplantation have good predictive performance, but the overall risk of bias is high. In the future, large-sample, multicenter and high-quality prospective clinical studies should be carried out to optimize the predictive models, so as to improve their predictive ability and clinical application value.

OBJECTIVE To investigate the clinical characteristics of euglycemic diabetic ketoacidosis （euDKA） induced by empagliflozin， and provide references for safe medication. METHODS Case reports of euDKA induced by empagliflozin were retrieved and analyzed from PubMed， Web of Science， CNKI， and Wanfang Data. The Naranjo’s scale was adopted to assess the causal relationship between empagliflozin and euDKA. RESULTS A total of 29 patients were enrolled， including 16 males and 13 females，with a median age of 58 years. All patients were diagnosed with type 2 diabetes mellitus； 22 patients had at least one comorbidity. The median time to euDKA onset was 60 days after administration， and 7 cases occurred within 2 weeks of treatment. Perioperative periods，fasting，and low-carbohydrate or ketogenic diets were the main predisposing factors. Common presentations included nausea，vomiting， fatigue， tachypnea，and tachycardia. The causal relationship between empagliflozin and euDKA was assessed as “probable” in all cases. According to adverse reaction severity grading， 13 cases were grade 3 （severe） and 16 cases were grade 4 （life-threatening）. All patients discontinued empagliflozin and recovered after corresponding treatment. CONCLUSIONS euDKA is a serious adverse reaction to empagliflozin， which mostly occurs early in treatment. Perioperative periods， fasting， and ketogenic diets are prone to induce euDKA. Elderly patients and those with comorbidities are at higher risk. Risk assessment should be conducted before clinical administration； blood ketones and acid-base monitoring should be strengthened in the early medication period； withhold the drug before elective surgery， avoid prolonged fasting；upon diagnosis， discontinue empagliflozin and initiate intravenous insulin， provide fluid resuscitation promptly， and use other treatments to improve patient prognosis.

ObjectiveTo explore whether the intestinal absorption solution containing Banxia Xiexintang （BXT） can inhibit the invasion and migration of gastric cancer cells by interfering with the stromal cell-derived factor 1 （SDF1）-CXC chemokine receptor 4 （CXCR4） axis in tumor-associated bone marrow mesenchymal stem cells （TA-BMSCs）. MethodsThe intestinal absorption solution containing BXT was prepared， and the optimal intervention concentration and duration for MFC cells were determined through the cell counting kit-8 （CCK-8） assay. A co-culture system was established comprising TA-BMSCs conditioned medium （TA-BMSCs-CM） and gastric cancer MFC cells. The experiment was conducted with a blank control group， a TA-BMSCs-CM group， an SDF1 inhibitor （LY2510924） group， and intervention groups with varying concentrations （55%， 70%， 85%） of the intestinal absorption solution containing BXT. Cell proliferation was assessed by the CCK-8 assay. Horizontal and vertical cell migration were evaluated via scratch and Transwell assays， respectively. Cell invasion was examined by a Transwell assay with Matrigel. Cell apoptosis was detected by flow cytometry. The levels of factors such as SDF1， matrix metalloproteinase-9 （MMP-9）， and vascular endothelial growth factor A （VEGFA）， as well as the protein levels of macrophage migration inhibitory factor （MIF）， CXCR4， VEGFA， and MMP-9， were quantified by ELISA and Western blot， respectively. ResultsThe CCK-8 assay results indicated that compared with the 24 h intervention， the 48 h interventions with all concentrations of the intestinal absorption solution containing BXT increased the inhibition rate on MFC cells （P<0.01）. The half-maximal inhibitory concentration （IC₅₀） of the intestinal absorption solution containing BXT at the time point of 48 h was 68.51%， and subsequent intervention concentrations were selected as 55%， 70%， and 85%. Compared with the TA-BMSCs-CM group， the intestinal absorption solution containing BXT （particularly at concentrations of 70% 85%） suppressed the proliferation， migration， and invasion of MFC cells， promoted the cell apoptosis （P<0.05， P<0.01）， decreased the levels of SDF1， MMP-9， and VEGFA， and downregulated the protein levels of MIF， CXCR4， VEGFA， and MMP-9 （P<0.05， P<0.01）. The inhibitory effects of the intestinal absorption solution containing BXT were comparable to or superior to those of the SDF1 inhibitor （P<0.01）. ConclusionThe intestinal absorption solution containing BXT can inhibit the invasion and migration of gastric cancer cells by interfering with the SDF1-CXCR4 axis in TA-BMSCs. The underlying mechanism may involve the regulation of the MIF/SDF1/CXCR4 signaling pathway and its downstream effector molecules.

ObjectiveTo observe how Banxia Xiexintang affects programmed cell death 1 ligand 1 （PD-L1） expression induced by exosomes derived from gastric cancer cells in bone marrow mesenchymal stem cells （BMSCs） through the protein kinase B （Akt）/c-myelocytomatosis oncogene （c-Myc） signaling axis， and its effects on the migration of BMSCs and gastric cancer cells. MethodsExosomes were isolated from human gastric cancer NCI-N87 cells and identified by transmission electron microscopy and Western blot. Rat BMSCs were passaged and identified by immunofluorescence staining. A Transwell chamber was used to create a non-contact co-culture system for NCI-N87 exosomes and BMSCs. The experiment was designed with normal， model， Banxia Xiexintang （10% serum containing Banxia Xiexintang）， PD-L1 monoclonal antibody （10% blank serum containing PD-L1 antibody）， and combination （10% serum containing Banxia Xiexintang and 10% blank serum containing PD-L1 antibody） groups. The suspension of BMSCs was added to the upper chamber of each group， with the normal group receiving serum culture medium without exosomes in the lower chamber， and the model group receiving NCI-N87 exosomes. The Banxia Xiexintang group， PD-L1 monoclonal antibody group， and combination group received 10% serum containing Banxia Xiexintang， 10% blank serum containing PD-L1 monoclonal antibody， and 10% serum containing Banxia Xiexintang and 10% blank serum containing PD-L1 antibody， respectively， in the upper chamber. After 96 h， BMSCs from the upper chamber were collected， and the protein levels of p-Akt， Akt， c-Myc， and PD-L1， as well as the mRNA levels of Akt， c-Myc， and PD-L1， were determined by Western blot and Real-time PCR， respectively. The migration of BMSCs and NCI-N87 was assessed by the Transwell method. ResultsCompared with the normal group， the model group showed increases in protein levels of p-Akt， c-Myc， and PD-L1， as well as mRNA levels of c-Myc and PD-L1 （P<0.05， P<0.01）， and no significant change in the protein and mRNA levels of Akt. Compared with the model group， the Banxia Xiexintang group， PD-L1 monoclonal antibody group， and combination group showed decreases in protein levels of p-Akt， c-Myc， and PD-L1 （P<0.01）. In addition， they had significant effects on the protein and mRNA levels of Akt. The combination group showed greater reductions in the protein and mRNA levels of c-Myc and PD-L1 than the Banxia Xiexintang group and PD-L1 monoclonal antibody group （P<0.05）. Compared with the normal group， the model group showed increases in the number of migrating NCI-N87 and BMSCs （P<0.05， P<0.01）. Compared with the model group， the Banxia Xiexintang group， PD-L1 monoclonal antibody group， and combination group showed decreases in the number of migrating NCI-N87 and BMSCs （P<0.05， P<0.01）， with the combination group showing greater reductions in the number of migrating NCI-N87 and BMSCs than the Banxia Xiexintang group and PD-L1 monoclonal antibody group （P<0.01）. ConclusionBanxia Xiexintang can lower the PD-L1 expression induced by gastric cancer cell-derived exosomes in BMSCs induced and inhibit the migration of BMSCs and gastric cancer cells. Moreover， it has a synergistic effect when being used together with PD-L1， possibly related to the regulation of the Akt/c-Myc signaling axis.

In a healthy human, the airway mucus forms a thin, protective liquid layer covering the surface of the respiratory tract. It comprises a complex blend of mucin, multiple antibacterial proteins, metabolic substances, water, and electrolytes. This mucus plays a pivotal role in the lungs' innate immune system by maintaining airway hydration and capturing airborne particles and pathogens. However, heightened mucus secretion in the airway can compromise ciliary clearance, obstruct the respiratory tract, and increase the risk of pathogen colonization and recurrent infections. Consequently, a thorough exploration of the mechanisms driving excessive airway mucus secretion is crucial for establishing a theoretical foundation for the eventual development of targeted drugs designed to reduce mucus production. Across a range of lung diseases, excessive airway mucus secretion manifests with unique characteristics and regulatory mechanisms, all intricately linked to mucin. This article provides a comprehensive overview of the characteristics and regulatory mechanisms associated with excessive airway mucus secretion in several prevalent lung diseases.

Polygonati Rhizoma demonstrates significant potential for addressing both chronic and hidden hunger. The supply of high-quality seedlings is a primary factor influencing the development of the Polygonati Rhizoma industry. Warm water soaking is often used in agriculture to promote the rapid germination of seeds, while its application and molecular mechanism in Polygonati Rhizoma have not been reported. To rapidly obtain high-quality seedlings, this study treated Polygonatum kingianum var. grandifolium seeds with sand storage at low temperatures, warm water soaking, and cultivation temperature gradients. The results showed that the culture at 25 ℃ or sand storage at 4 ℃ for 2 months rapidly broke the seed dormancy of P. kingianum var. grandifolium, while the culture at 20 ℃ or sand storage at 4 ℃ for 1 month failed to break the seed dormancy. Soaking seeds in 60 ℃ warm water further increased the germination rate, germination potential, and germination index. Specifically, the seeds soaked at 60 ℃ and cultured at 25 ℃ without sand storage treatment(Aa25) achieved a germination rate of 78. 67%±1. 53% on day 42 and 83. 40%±4. 63% on day 77. The seeds pretreated with sand storage at 4 ℃ for 2 months, soaked in 60 ℃ water, and then cultured at 25 ℃ achieved a germination rate comparable to that of Aa25 on day 77. Transcriptomic analysis indicated that warm water soaking might promote germination by triggering reactive oxygen species( ROS), inducing the expression of heat shock factors( HSFs) and heat shock proteins( HSPs), which accelerated DNA replication, transcript maturation, translation, and processing, thereby facilitating the accumulation and turnover of genetic materials. According to the results of indoor controlled experiments and field practices, maintaining a germination and seedling cultivation environment at approximately 25 ℃ was crucial for the one-year seedling cultivation of P. kingianum var. grandifolium.

OBJECTIVE: Although dietary preferences influence chronic diseases, few studies have linked dietary preferences to mortality risk, particularly in large cohorts. To investigate the relationship between dietary preferences and mortality risk (all-cause, cancer, and cardiovascular disease [CVD]) in a large adult cohort. METHODS: A cohort of 1,160,312 adults (mean age 62.48 ± 9.55) from the Shenzhen Healthcare Big Data Cohort (SHBDC) was analyzed. Hazard ratios ( HRs) for mortality were estimated using the Cox proportional hazards model. RESULTS: The study identified 12,308 all-cause deaths, of which 3,865 (31.4%) were cancer-related and 3,576 (29.1%) were attributed to CVD. Compared with a mixed diet of meat and vegetables, a mainly meat-based diet (hazard ratio [ HR] = 1.13; 95% confidence interval [ CI]: 1.02, 1.27) associated with a higher risk of all-cause mortality, while mainly vegetarian ( HR = 0.87; 95% CI: 0.78, 0.97) was linked to a reduced risk. Furthermore, there was a stronger correlation between mortality risk and dietary preference in the > 65 age range. CONCLUSION A meat-based diet was associated with an increased risk of all-cause mortality, whereas a mainly vegetarian diet was linked to a reduced risk.
