Since 2005, organ donation and transplantation in China has undergone thorough reform, which complies with legislation requirements and ethical principles established by the World Health Organization(WHO). Reform in China has demonstrated the unwavering confidence and utmost determination of the Chinese government and the Chinese transplantation community. The year 2015 marked a historic turning point when voluntary donations from Chinese citizens became the sole legitimate source for organ transplantation. Since 2015, China has gradually established and refined the “Chinese Mode” and “China System” for organ donation and transplantation, fulfilling its political pledge of reform, and has garnered international recognition, and fostered a social culture which promotes organ donation. This article reviewed the history of reform on organ donation and transplantation in China, presented a new pattern of establishment of organ donation system in the new era of the country, and the direction of advances in the future.展开更多

文摘China’s healthcare system faces increasing challenges,including surging medical costs,resource allocation imbalances favoring large hospitals,and ineffective referral mechanisms.The lack of a unified strategy integrating standardized coverage with personalized payment compounds these issues.To this end,this study proposes a risk-sharing reform strategy that combines equal coverage for the same disease(ECSD)with an individualized out-of-pocket(I-OOP)model.Specifically,the study employs a Markov model to capture patient transitions across health states and care levels.The findings show that ECSD and I-OOP enhance equity by standardizing disease coverage while tailoring costs to patient income and facility type.This approach alleviates demand on high-tier hospitals,promoting primary care utilization and enabling balanced resource distribution.The study’s findings provide a reference for policymakers and healthcare administrators by presenting a scalable framework that is aligned with China’s development goals with the aim of fostering an efficient,sustainable healthcare system that is adaptable to regional needs.

文摘College students’safety education is an important part of the fundamental task of fostering virtue through education in colleges and universities.A questionnaire survey at J University shows that the popularization degree and teaching satisfaction of college students’safety education are relatively high,but the teaching content and teaching forms still need improvement.With the rapid development of artificial intelligence technology and considering the char-acteristics of college students’online learning in the new era,carrying out the SPOC+PBL blended teaching reform not only helps to enhance the effectiveness of theoretical and practical teaching but also contributes to optimizing the teach-ing evaluation and feedback mechanism and strengthening students’problem-solving abilities.Therefore,we should adhere to the goal orientation,meticulously design the teaching plan,highlight the student-centered approach,focus on integrating teaching resources,strengthen process management,promptly provide feedback and guidance,empower with data,and continuously improve teaching evaluation.Thus,a student-centered SPOC+PBL blended teaching sys-tem can be constructed to empower the transformation and innovation of talent cultivation in higher education.
