Background: and Purpose Antiplatelets are often used before direct oral anticoagulant (DOACs) initiation after an acute ischemic stroke related to atrial fibrillation (AF), but the evidence is weak. Here, we explored the risks and benefits of this approach. Methods: A post-hoc analysis of ELAN (Early versus Late Initiation of Direct Oral Anticoagulants in Post-ischemic Stroke Patients with Atrial Fibrillation) trial data (NCT03148457) was conducted to compare the risk of recurrent ischemic stroke, systemic embolism, major bleeding (extracranial or intracranial hemorrhage [ICH]), and vascular death within 30 days (as a composite and as individual outcomes) in participants treated with and without antiplatelets before DOAC initiation after an AF-associated ischemic stroke. We used both logistic and cause-specific Cox proportional hazards regression in inverse probability of treatment weighted models to account for confounding. We calculated the net benefit of antiplatelet use by subtracting the weighted rate of excess bleeding events attributable to antiplatelets from the rate of excess ischemic events possibly prevented by antiplatelets. Results: Among 2,013 participants (median age 77 years, 45.5% female), 1,090 (54.1%) used antiplatelets, and 70 (3.5%) experienced the composite outcome. Antiplatelet use was not associated with the composite outcome (inverse probability of treatment weighted odds ratio [ORweighted] 1.06, 95% confidence interval [CI] 0.66–1.72; inverse probability of treatment weighted hazard ratio [HRweighted] 1.06, 95% CI 0.65–1.72), but showed a lower risk of ischemic stroke recurrence (ORweighted 0.58 [0.30–1.08], HRweighted 0.57 [0.30–1.10]), and a higher risk of major bleeding (ORweighted 1.76 [0.56–6.63], HRweighted 1.88 [0.56–6.39]). Its net benefit was +0.57 (95% CI -1.25 to +2.34) to +0.30 (-1.82 to +2.27) weighted events/100 person-months for ICH weights 1.5 to 3.1. Conclusion Following an AF-associated ischemic stroke, we found a lower risk of recurrence and no signs of net harm with antiplatelet use before DOAC initiation, despite an increased risk of bleeding.

Objective: To explore the association between the Internet usage characteristics and suicidal ideation among vocational high school students, so as to provide a theoretical basis for precise intervention of suicide among vocational high school students. Methods: A total of 1 781 students were recruited from three vocational high schools in Wuhan and Xianning in March 2023 by using the cluster random sampling method. The Columbia-Suicide Severity Rating Scale and Revised Chen Internet Addiction Scale were used to measure suicidal ideation and Internet addiction, respectively. LASSO regression model was used to select influential factors related to suicidal ideation, and the gradient boosting decision tree algorithm XGBoost was used to develop prediction models and evaluate predictive performance. By calculating the SHAP values, the contribution of each influential factor was quantified. Results: The prevalence of suicidal ideation among vocational high school students was 42.22% and prevalence of Internet addiction was 26.39%. LASSO regression results indicated that age, gender, experience of being left behind, parental relationship, holding a class cadre position, using the Internet for learning, Internet use during dawn, morning and late night, Internet addiction, and depressive symptoms were all the influential factors of suicidal ideation among vocational high school students ( β= -0.05 , 0.29, 0.09, 0.27, 0.10, -0.01, 0.09, 0.05, 0.24, 0.28, 0.78, all P <0.05). The AUC of the prediction model was 0.75. The results based on SHAP values indicated that all influential factors identified through multivariate analysis contributed positively to the model predictions ( SHAP >0). Among these, depressive symptoms and parental relationship had the greatest impact on suicidal ideation ( SHAP =0.77, 0.26), and the joint effect of features with higher contribution could improve the prediction probability. Conclusions Depressive symptoms, parental relationships, Internet addiction, and time of Internet use are most important risk factors of suicidal behaviors for vocational high school students. Thus, effective interventions should be conducted to reduce their suicidal ideation.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

BACKGROUND: Owing to the high prevalence of antibiotic resistance in Helicobacter pylori ( H. pylori ) in China, bismuth-containing quadruple therapies have been recommended for H. pylori eradication. This study compared the efficacy and safety of quadruple regimens containing vonoprazan vs . esomeprazole for H. pylori eradication in a patient population in China. METHODS: This was a phase 3, multicenter, randomized, double-blind study. Patients with confirmed H. pylori infection were randomized 1:1 to receive quadruple therapy for 14 days: amoxicillin 1000 mg and clarithromycin 500 mg after meals, bismuth potassium citrate 600 mg before meals, plus either vonoprazan 20 mg or esomeprazole 20 mg before meals, all twice daily. The primary outcome was the eradication rate of H. pylori , evaluated using a 13 C urea breath test at 4 weeks after treatment. The non-inferiority margin was at 10%. RESULTS: The study included 510 patients, 506 of whom completed the follow-up assessment. The primary analysis revealed eradication rates of 86.8% (210/242) and 86.7% (208/240) for vonoprazan and esomeprazole therapy, respectively (treatment difference: 0.1%; 95% confidence interval [CI]: -5.95, 6.17; non-inferiority P  = 0.0009). Per-protocol analysis showed eradication rates of 87.4% for vonoprazan and 86.3% for esomeprazole (treatment difference: 1.2%; 95% CI: -5.03, 7.36; non-inferiority P  = 0.0004). Vonoprazan and esomeprazole were well tolerated, with similar safety profiles. CONCLUSION: Vonoprazan was found to be well-tolerated and non-inferior to esomeprazole for eradicating H. pylori in patients from China. TRIAL REGISTRATION ClinicalTrials.gov , NCT04198363.

Synthetic biology is a crucial tool for the development of the bio-industry and bio-economy, representing a significant aspect of new quality productive forces. As a core course for graduate students in bioengineering, Synthetic Biology plays a vital role in ensuring the supply of essential talents for the development of the bio-industry in the new era. To better serve regional economic development and provide high-level talents for China's progress in the bio-industry, we analyzed typical issues encountered in the past teaching activities, set up a multi-disciplinary teaching team, optimized the course contents, adjusted the teaching mode, and mobilized students' learning interest. With the application of scientific research project as the starting point, we guided students to think and discuss deeply through the simulation of application writing and project defense, which improved students' critical thinking and innovative thinking. With industrialization as a focus, we explored a new training model combining production, education, and research through the joint practice base of the university and enterprises introduced typical cases of biomanufacturing to encourage students to engage in scientific research. The teaching reform significantly enhances the comprehensive abilities and national sentiments of graduate students. This paper hopes to serve as a reference for colleagues engaged in teaching in this field.
