Objective To analyze the prevalence characteristics and influencing factors of metabolic syndrome (MS) in people aged 35-75 years in Hubei Province. Methods The follow-up data from 2016 to 2022 in the early screening and comprehensive intervention project for high-risk cardiovascular population in Hubei Province were collected. SAS 9.4 software was used to conduct 2-test and multivariate logistic regression to analyze the prevalence of MS and its influencing factors. Results Among the 89 199 subjects, 24 757 were affected by MS, with a prevalence rate of 27.75% and a standardized rate of 23.55%. Among the various components of MS, the prevalence of abnormal blood pressure was the highest, at 70.88%, and the standardized rate was 59.32%. Secondly, abnormal blood glucose was 36.26%, and the standardized rate was 30.04%. Central obesity was 33.12%, and the standardized rate was 30.28%. Hypertriglyceridemia was 32.90%, and the standardized prevalence rate was 32.70%. The rate of low HDL-C syndrome was 10.25%, and the standardized rate was 11.67%. The results of multivariate logistic regression analysis showed that the risk of MS increased with age, and the risk of MS in urban residents was lower than that in rural residents (OR=0.835, 95%CI: 0.77-0.886). Administrative and professional workers had a higher risk of MS than farmers (OR=1.313, 95%CI:1.194-1.445). Overweight, obesity, central obesity, history of self-reported hypertension, history of self-reported diabetes, and history of self-reported dyslipidemia were associated with a higher risk of MS, and the differences were statistically significant (P < 0.001). Conclusion The prevalence of MS is high in people aged 35-75 years in Hubei Province. On the basis of comprehensive intervention, focus monitoring should be strengthened to control the risk factors of MS and reduce the risk of cardiovascular and cerebrovascular diseases.

Impaired glucose regulation （IGR） is an intermediate state between normal blood glucose and diabetes， falling under the category of splenic pure heat in traditional Chinese medicine （TCM）. The core pathogenesis is believed to be the dysfunction of the zang-fu （脏腑） organs， leading to metabolic abnormalities of subtle essence and the generation of "turbid pathogen". Its accumulation can block qi movement， damage the vessel collaterals， and promote the disease progression toward diabetes. The concept of "turbid pulse" is proposed as an early sign of IGR， characterized by full and heavy sensation with stagnated and astringent circulation， which can serve as an effective supplement to clinical screening. The differentiation and treatment approach in clinical practice is summarized as follows. If the ascending and descending mechanisms of qi movement in the middle jiao （焦） are disrupted， with mutual interference between the clear and the turbid， treatment should focus on harmonizing the ascending and the descending， and transforming dampness with aromatic medicinals. For spleen-stomach qi deficiency due to long-term restriction of the spleen and stomach's function of transportation and transformation， it is suggested to fortify spleen and harmonize stomach， and transport turbid with sweet-warm medicinals. For spleen deficiency and liver constraint induced by internal generation of damp-heat in the middle jiao， the treatment should focus on soothing the liver and opening constraint， and directing the turbid downward with sour-sweat medicinals. For solid accumulation and stagnation caused by liver qi constraint， it is recommended to unblock intestine and remove stagnation， and discharge turbid with bitter-cold medicinals. When the disease is transmitted to the lower jiao， and the kidneys are affected， the treatment should be regulating spleen and kidney， and rectifying turbid with salty-sour medicinals. In conclusion， it is emphasized to promote the transformation of turbid pathogen to restore metabolic homeostasis， providing methods for the clinical diagnosis and treatment of IGR.

ObjectiveThis study aimed to evaluate the effectiveness of various statistical methods based on the complementary sensitivity analysis framework recommended by the European Medicines Agency (EMA) in Alzheimer’s disease clinical trials, providing a reference for statistical practice that meets international regulatory standards for similar studies. MethodsBased on longitudinal data from a phase Ⅲ clinical trial for the treatment of Alzheimer’s disease, the change from baseline in Alzheimer’s Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) score from baseline at week 26 (with a decrease indicating cognitive improvement) was used as the primary outcome measure. This study employed a mixed-effects model with repeated measures (MMRM) under the assumption of missing at random (MAR) as the primary analysis, while using critical point analysis, rank-based analysis, and slope-based analysis for sensitivity verification. A systematic comparison of the efficacy estimation results from the four analytical methods was conducted to compare the consistency and robustness differences in research conclusions across different analytical strategies. ResultsThe primary analysis results from the MMRM showed that the improvement in ADAS-Cog score from baseline at week 26 in the treatment group was superior to that in the placebo group (LSMD=-3.22, 95%CI: -4.55 to -1.88, P<0.001). Both rank-based analyses and slope-based analyses indicated significant differences between groups (both P<0.001). Critical point analyses revealed that the treatment effect was negative under most reasonable missing hypothesis scenarios, with the effect value only potentially turning positive in extreme non-random missing scenarios. There was no overall reversal of the efficacy conclusion. ConclusionThe combination of MMRM, critical point analysis, rank-based analysis, and slope-based analysis can effectively address the challenge of missing data in clinical trials for progressive diseases. This strategy fully complies with international regulatory standards, verifies efficacy conclusions from multiple perspectives, and enhances the credibility and scientific validity of clinical trial results. It can provide a practical reference for statistical analysis of missing data in similar clinical trials for progressive diseases.

Implementation science aims to facilitate the efficient dissemination and sustainable application of evidence based interventions, and has accordingly generated a variety of theories, models, and frameworks. Among these, the Exploration, Preparation, Implementation, and Sustainment (EPIS) frameworkfunctions both as a process model and a determinant framework, emphasizing the staged and iterative nature of implementation, and systematically explaining the influence of multilevel factors on implementation processes and outcomes through four dimensions: outer context, inner context, bridging factors, and innovation factors. The EPIS framework has been widely applied in health and public service settings internationally, yet its use in China based research remains relatively limited. This article systematically introduces the core components and application methods of the EPIS framework, and illustrates its value in identifying key influencing factors, developing implementation strategies, and optimizing implementation outcomes through case examples from the health sector, aiming to provide a methodological reference for implementation research and the promotion of evidence based interventions in China.

Objective:To discuss the changes of adenosine deaminase 2(ADA2)activity in the serum of the systemic lupus erythematosus(SLE)patients,and to clarify its clinical value in the diagnosis and disease assessment of the SLE patients.Methods:According to the inclusion and exclusion criteria,69 SLE patients(SLE group)and 69 healthy controls(control group)were enrolled as study subjects.The disease activity of SLE patients was evaluated by SLE Disease Activity Index(SLEDAI).The ADA2 activity in the serum of the subjects in both groups was detected.The patients were further divided into subgroups based on the presence or absence of the following clinical symptoms:arthritis,myositis,hematuria,proteinuria,pyuria,alopecia,new rash,mucosal ulcer,pleuritis,hypocomplementemia,elevated anti-double-stranded DNA(anti-dsDNA)antibody,thrombocytopenia,and leukopenia.The differences in serum ADA2 activity between joint symptomatic group and joint asymptomatic group were analyzed.The diagnostic efficacy of serum ADA2 activity was evaluated by receiver operating characteristic(ROC)curve analysis.The correlation between ADA2 activity and disease activity in the SLE patients was analyzed by Spearman correlation analysis.Results:Compared with control group,the ADA2 activity in the serum of the patients in SLE group was significantly increased(P<0.01).The ROC analysis results showed that when the cut-off value of ADA2 activity was set at 8.5 U·L-1,the diagnostic performance was optimal,with an area under the curve(AUC)of 0.879(95%CI:0.817-0.940),the specificity was 89.86%,and the sensitivity was 75.36%.The serum ADA2 activity was positively correlated with disease activity in the SLE patients(r=0.32,P=0.007).The subgroup analysis of clinical symptoms results showed that the serum ADA2 activity in the SLE patients with symptoms was significantly higher than that in the SLE patients without symptoms(P<0.01).No significant differences were observed in serum ADA2 activity between the SLE patients with and without myositis,hematuria,proteinuria,pyuria,alopecia,new rash,mucosal ulcer,pleuritis,hypocomplementemia,elevated anti-dsDNA antibody,thrombocytopenia,or leukopenia(P>0.05).Conclusion:The serum ADA2 activity is increased in the SLE patients and can serve as a diagnostic marker for SLE.Serum ADA2 activity is positively correlated with disease activity and is associated with arthritis in the SLE patients,suggesting its potential as an indicator for disease assessment and monitoring.

Objective:To investigate the effect of polystyrene microplastics(PS-MPs)combined with high-fat treatment on vascular endothelial cells.Methods:Human umbilical vein endothelial cells(HUVECs)were cultured in the DMEM medium containing 5%fe-tal bovine serum.HUVECs were treated with conventional culture,high-fat treatment,and PS-MPs combined with high-fat treatment.The experiment was conducted in the three groups of control group,high-fat treatment group and PS-MPs+high-fat treatment group.CCK-8 assay was used to measure cell viability,F-actin staining was used to observe cell morphological changes,and flow cytometry,scratch assay,and tube formation assay were used to measure the apoptosis,migration,and tube-forming ability of cells.Results:After HUVECs were exposed to the high-fat environment,there was a significant reduction in cell viability,shrinkage of cells,a signifi-cant increase in cell apoptosis,and significant reductions in cell migration and tube-forming ability.Compared with the high-fat treat-ment group,there were no significant changes in cell viability,cell morphology,cell apoptosis,and cell migration ability after PS-MPs combined with high-fat treatment,but the tube-forming ability of cells was further impaired.Conclusion:High-fat treatment will affect cell viability,change cell morphology,and damage vascular endothelial cell function,and PS-MPs combined with high-fat treat-ment can aggravate the damage of vascular endothelial cell function.

Objective To analyze the influencing factors of feeding intolerance in the patients with se-vere traumatic brain injury(STBI).Methods The clinical data in 96 patients with STBI in this hospital from January 2023 to December 2023 were retrospectively analyzed.The patients were divided into the tolerance group and non-tolerance group according to whether the intolerance developed during the feeding process.The general condiction,laboratory detection,treatment measures and enteral nutrition implementation condition were recorded.The multivariate logistic regression was used to analyze the influencing factors of feeding intol-erance in STBI patients.Results Among 96 patients,43 cases(44.79％)developed the feeding intolerance.The results of univariate analysis showed that GCS score,blood glucose,serum albumin,starting time of en-teral nutrition,sedative drugs use,mechanical ventilation,antacids use,combined use of antibiotics,vasoactive drugs use,mild hypothermia therapy and prone position ventilation were related with the feeding intolerance in STBI patients.The multivariate logistic regression analysis showed that combined use of antibiotics(OR=43.628,P=0.002),use of vasoactive drugs(OR=140.211,P=0.004),delayed initiation of enteral nutrition(OR=44.529,P=0.009),mild hypothermia treatment(OR=439.599,P=0.001)and prone position venti-lation(OR=288.702,P=0.014)were the independent influencing factors of feeding intolerance in STBI pa-tients.Conclusion STBI patients are prone to develop the feeding intolerance.If there is no contraindication,the enteral nutrition should be initiated as early as possible,and the personalized prevention and treatment measures aiming at various influencing factors should be formulated.
