Background and Objectives: The Fractional Flow Reserve and Intravascular UltrasoundGuided Intervention Strategy for Clinical Outcomes in Patients with Intermediate Stenosis (FLAVOUR) trial demonstrated non-inferiority of fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) compared with intravascular ultrasound (IVUS)-guided PCI. We sought to investigate the cost-effectiveness of FFR-guided PCI compared to IVUS-guided PCI in Korea. Methods: A 2-part cost-effectiveness model, composed of a short-term decision tree model and a long-term Markov model, was developed for patients who underwent PCI to treat intermediate stenosis (40% to 70% stenosis by visual estimation on coronary angiography).The lifetime healthcare costs and quality-adjusted life-years (QALYs) were estimated from the healthcare system perspective. Transition probabilities were mainly referred from the FLAVOUR trial, and healthcare costs were mainly obtained through analysis of Korean National Health Insurance claims data. Health utilities were mainly obtained from the Seattle Angina Questionnaire responses of FLAVOUR trial participants mapped to EQ-5D. Results: From the Korean healthcare system perspective, the base-case analysis showed that FFR-guided PCI was 2,451 U.S. dollar lower in lifetime healthcare costs and 0.178 higher in QALYs compared to IVUS-guided PCI. FFR-guided PCI remained more likely to be cost-effective over a wide range of willingness-to-pay thresholds in the probabilistic sensitivity analysis. Conclusions Based on the results from the FLAVOUR trial, FFR-guided PCI is projected to decrease lifetime healthcare costs and increase QALYs compared with IVUS-guided PCI in intermediate coronary lesion, and it is a dominant strategy in Korea.

Objective: To explore the association between dietary patterns and overweight and obesity among primary and middle school students, so as to provide the guidance of diet balance and obesity prevention for students. Methods: Students from 11 primary and middle schools in Tongzhou District, Beijing Municipality, were selected using the stratified cluster sampling method. Demographic information was collected through a general questionnaire, and dietary intake types and frequencies over the past week were assessed using a food frequency questionnaire. Dietary patterns were determined using factor analysis, and the dietary pattern factor scores were divided into Q1, Q2, Q3, and Q4 groups based on quartiles. Height and weight were collected through physical examinations, and Z-scores of body mass index adjusted for gender and age were calculated to assess overweight and obesity. The association between dietary patterns and overweight and obesity was analyzed using a multivariable logistic regression model. Results: A total of 1 485 students were surveyed, including 745 males (50.17%) and 740 females (49.83%). The mean age was (12.87±2.86) years. Three dietary patterns were identified: animal and plant protein dietary pattern, high-fat and high-sugar dietary pattern, and vegetable-fruit-dairy dietary pattern. The detection rates of overweight and obesity were 42.57%, 48.42%, and 34.75%, respectively, with statistically significant differences (P<0.05). Multivariable logistic regression analysis showed that compared with the vegetable-fruit-dairy dietary pattern, the animal and plant protein dietary pattern (OR=1.406, 95%CI: 1.084-1.823) and the high-fat and high-sugar dietary pattern (OR=2.137, 95%CI: 1.643-2.779) were associated with a higher risk of overweight and obesity among primary and middle school students. Compared with the Q1 group of dietary pattern factor scores, the Q3 group (OR=1.631, 95%CI: 1.206-2.208) and Q4 group (OR=1.965, 95%CI: 1.446-2.671) of the high-fat and high-sugar dietary pattern had an increased risk of overweight and obesity, while the Q4 group of the vegetable-fruit-dairy dietary pattern (OR=0.551, 95%CI: 0.406-0.747) had a reduced risk of overweight and obesity. There was no statistical association between factor scores of animal and plant protein dietary pattern and overweight and obesity (all P>0.05). Conclusions The animal and plant protein dietary pattern and the high-fat and high-sugar dietary pattern are associated with a higher risk of overweight and obesity among primary and middle school students. Within the same dietary pattern, the more inclined students are to the high-fat and high-sugar dietary pattern, the higher their risk of overweight and obesity, while the more inclined they are to the vegetable-fruit-dairy dietary pattern, the lower their risk of overweight and obesity.

OBJECTIVE To investigate the effects of Ephedra-Cinnamomum couplet medicinals on respiratory function and airway inflammation in rats with asthma of cold-fluid retention in lung syndrome and its mechanism. METHODS Sixty Wistar rats were randomly divided into blank group， model group， dexamethasone group [1 mg/（kg·d）]， and Ephedra-Cinnamomum low-， medium-， high-dose groups [0.234， 0.936， 1.872 g/（kg·d）]， with 10 rats in each group. The model and treatment groups were sensitized by intraperitoneal injection of antigen solution （ovalbumin 100 mg + aluminum hydroxide 100 mg） and challenged with 1% ovalbumin nebulization， along with exposure to a cold environment and ingestion of cold water， to establish the asthma model with cold-fluid retention in lung syndrome. From day 2， rats received corresponding drugs or normal saline intragastrically， once a day， for 21 consecutive days. The general behavioral changes in each group of rats were observed during the experimental process. The lung function parameters [peak expiratory flow （PEF）， airway resistance （Raw）， functional residual capacity （FRC）， expiratory flow at 50% of forced vital capacity （EF50%）] Δ 基金项目 国家自然科学基金青年科学基金项目（No.82004233）； were measured before modeling and after the last medication as well as serum contents of interleukin-6 （IL-6）， IL-13， tumor necrosis factor- α （TNF- α） and interferon-gamma （IFN- γ） after the last medication were determined； the histopathological morphological changes in the lung tissues of rats were also observed； mRNA expressions of IL-6， IL-3， TNF-α， IFN-γ， thymic stromal lymphopoietin （TSLP）， and Toll-like receptor 4 （TLR4）， as well as protein expressions of TSLP and TLR4 were determined in lung tissue. RESULTS Compared with model group， the lung tissue damage of rats was relieved significantly； Raw， FRC， the contents and mRNA expression levels of IL-6， IL-13 and TNF-α， as well as the mRNA and protein expressions of TSLP and TLR4 were significantly decreased （P＜0.05）， while the contents and mRNA expressions of PEF， EF50 % and IFN-γ were significantly increased in the dexamethasone group and Ephedra-Cinnamomum medium- and high-dose groups （P＜0.05）. Moreover， only a few rats in the two groups exhibited typical symptoms of asthma. CONCLUSIONS Ephedra-Cinnamomum couplet medicinals improve respiratory function and ameliorate airway inflammation in asthma rats with cold-fluid retention in lung syndrome， the mechanism of which may be associated with inhibiting TSLP/TLR4 signaling pathway and modulating Th1/Th2 imbalance.

Objective To investigate the association between lifestyle and risk of heart disease and diabetes in the elderly population in Xi'an City. Methods From January 2021 to January 2024, a staged cluster sampling method was used to investigate the lifestyle and the occurrence of heart disease and diabetes in elderly population aged 60 years and above in the communities of Xi'an. Multivariate logistic regression was used to analyze the relationship between lifestyle and the risk of heart disease and diabetes. Results A total of 413 elderly people were investigated, of which 31.96% had heart disease, 27.12% had diabetes, and 10.90% had diabetes with heart disease. Multivariate logistic regression analysis revealed that age, BMI, family history, sweet food preference, smoking, and sitting and lying for a long time were risk factors for diabetes in the elderly population (P<0.05). Age, BMI, family history, history of diabetes, preference for salted products, smoking, drinking, and sitting and lying for a long time were risk factors for heart disease in the elderly population (P<0.05). Conclusion The incidence rates of heart disease and diabetes are high in the elderly population in Xi'an City. The risk of diabetes is related to unhealthy lifestyles such as sweet food preference, smoking, and sitting and lying for a long time, while heart disease is related to unhealthy lifestyles such as preference for salted products, smoking, drinking, and sitting and lying for a long time.

Probiotics play a crucial role in colon cancer treatment by metabolizing prebiotics to generate short-chain fatty acids (SCFAs). Colon cancer patients are frequently propositioned to supplement with probiotics to enhance the conversion and utilization of prebiotics. Nevertheless, the delivery and colonization of probiotics is hindered by the harsh conditions of gastrointestinal tract (GIT). Here, we devised a straightforward yet potent modified prebiotic-based "shield" (Gelatin-Inulin, GI), employing dietary inulin and natural polymer gelatin crosslinked via hydrogen bonding for enveloping Lactobacillus reuteri (Lr) to formulate synbiotic hydrogel capsules (Lr@Gl). The GI "shield" serves as a dynamic barrier, augmenting the resistance of Lr to gastric acid and facilitating its bioactivity and adherence in the GIT, synergizing with Lr to elicit an anti-tumor effect. Simultaneously, Lr@GI demonstrates anti-tumor effects by depleting glutathione to release reactive oxygen species, accompanied by the activation of NLRP3 (NOD-like receptor family pyrin domain containing 3), and the induction M1 macrophage polarization. Furthermore, Lr@GI can not only promote the recovery of intestinal barrier but also regulate intestinal flora, promoting the production of SCFAs and further exerting anti-tumor effect. Crucially, Lr@GI also potentiates the anti-tumor effect of 5-Fluorouracil. The construction and synergistic anti-tumor mechanism of synbiotic hydrogel capsules system provide valuable insights for gut microbial tumor therapy.

Objective:To investigate the differences and prognostic value of serum myeloid-related proteins 8 and 14 (Mrp 8/14) in patients with acute respiratory distress syndrome (ARDS) induced by pulmonary and extrapulmonary sepsis.Methods:A retrospective cohort study was conducted to collect the general clinical data of septic ARDS patients admitted to the intensive care unit (ICU) of Nanjing Hospital of Nanjing Medical University from August 2021 to February 2024. The serum levels of Mrp 8/14 were detected within 24 hours after admission. According to whether the patients died during ICU stay, the patients with pulmonary ARDS and extrapulmonary ARDS induced by sepsis were divided into survival and death groups, respectively. The differences of Mrp 8/14 and other clinical data between the two groups were compared. Logistic regression analysis was used to analyze the prognostic factors of septic patients with pulmonary ARDS and extrapulmonary ARDS. The receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of serum Mrp 8/14 for the prognosis of patients with pulmonary ARDS and extrapulmonary ARDS.Results:A total of 138 patients with sepsis-induced ARDS were enrolled in this study, including 79 patients with pulmonary ARDS and 59 patients with extrapulmonary ARDS. Compared to the death group, the level of serum Mrp 8/14 was significantly lower [Mrp 8/14: 22.90 (17.91, 30.88) μg/mL vs. 10.73 (7.15, 17.20) μg/mL, P<0.05]. Multivariate logistic regression analysis demonstrated that the serum Mrp 8/14 level was an independent risk factor for the prognosis of pulmonary ARDS patients only during the ICU stay ( OR=1.253, 95% CI: 1.110-1.414, P<0.05). ROC curve analysis showed that the area under the curve of serum Mrp 8/14 for the prediction of death in ARDS patients with pulmonary sepsis during ICU stay was 0.855 (95% CI: 0.773-0.938, P<0.05), the cut-off value was 19.230 μg/mL, the sensitivity was 0.718, the specificity was 0.925, and the Yonden index was 0.405. Conclusion:Serum Mrp 8/14 is an effective prognostic indicator for the mortality of ARDS patients with pulmonary sepsis during ICU hospitalization.
