摘要：Nanomaterials have been applied as antibacterial agents by virtue of their unique functioning mechanism different from that of conventional *** oxide nanoparticles(CeO2 NPs)are important antibacterial agents due to their relatively low toxicity to normal cells and their distinct antibacterial mechanism based on the reversible conversion between two valence states of Ce(III)/Ce(IV).Some studies have been conducted to explore their antibacterial activities;however,systematic research reviews on the related mechanisms and influencing factors are still quite *** this review,we discuss the plausible mechanisms of the antibacterial activity of CeO2 NPs,analyze different influencing factors,and summarize various research reports on antibacterial effects on *** and *** also propose the potential applications and prospects,and hope to provide an in-depth understanding on the antibacterial mechanism and a better guidance to the design and applications of this promising antibacterial material in the future.

摘要：针对构建基于微服务架构的互联网医院在访问控制安全性方面的需求,线上诊疗业务繁多且复杂,其数据特性既包含开放性也涉及高度的私密性,用户登录系统以及客户端应用程序成为权限攻击的主要目标。此外,业务应用在实现认证鉴权功能时面临集成门槛高、技术难度大、开发周期长以及跨平台兼容性等挑战,目前缺乏可复用的成功案例。为解决这些问题,本研究采用角色访问控制模型设计权限分配策略,基于Spring Security框架,结合JWT与OAuth 2.0协议,构建权限认证中心。该中心负责实现接入方和用户的登录认证、可信令牌的生成与授权,从而构建一个既安全又高效的平台鉴权体系。同时,采用前端报文传输及存储的加密技术确保数据安全性。通过权限的细粒度划分以及灵活的规则过滤链,有效提升了平台鉴权运算的效率。

摘要：针对互联网医疗模式下电子处方共享的现状,探索“互联网+处方共享”在医疗机构的实施方案,设计门诊处方共享平台的系统架构和系统功能,并从数据安全和应用安全两个层面探讨系统安全。该平台是一套基于SpringBoot框架开发的服务,采用SpringBoot 2.3、MyBatis、RabbitMQ等核心技术,前端采用Vue、AntDesign提供管理后台以快速搭建系统,通过Vant UI技术框架快速搭建微信小程序,H5等载体的多端应用提供了患者端、医生端、药师端的小程序。另外,系统通过接口平台和医院信息系统、合理用药系统、药店、医保支付等平台实现互联互通,打通“医”“药”“险”3个环节,实现线上线下一体化的电子处方共享服务。
