Intranasal administration of stem cell-derived exosomes for central nervous system diseases

Exosomes,lipid bilayer-enclosed small cellular vesicles,are actively secreted by various cells and play crucial roles in intercellular communication.These nanosized vesicles transport internalized proteins,mRNA,miRNA,and other bioactive molecules.Recent findings have provided compelling evidence that exosomes derived from stem cells hold great promise as a therapeutic modality for central nervous system disorders.These exosomes exhibit multifaceted properties including antiapoptotic,anti-inflammatory,neurogenic,and vasculogenic effects.Furthermore,exosomes offer several advantages over stem cell therapy,such as high preservation capacity,low immunogenicity,the ability to traverse the blood-brain barrier,and the potential for drug encapsulation.Consequently,researchers have turned their attention to exosomes as a novel therapeutic avenue.Nonetheless,akin to the limitations of stem cell treatment,the limited accumulation of exosomes in the injured brain poses a challenge to their clinical application.To overcome this hurdle,intranasal administration has emerged as a non-invasive and efficacious route for delivering drugs to the central nervous system.By exploiting the olfactory and trigeminal nerve axons,this approach enables the direct transport of therapeutics to the brain while bypassing the blood-brain barrier.Notably,exosomes,owing to their small size,can readily access the nerve pathways using this method.As a result,intranasal administration has gained increasing recognition as an optimal therapeutic strategy for exosomebased treatments.In this comprehensive review,we aim to provide an overview of both basic and clinical research studies investigating the intranasal administration of exosomes for the treatment of central nervous system diseases.Furthermore,we elucidate the underlying therapeutic mechanisms and offer insights into the prospect of this approach.

America’s Policy towards China under Two Administrations in the Context of Great Changes: Difference, Influence and Enlightenment

Under the great changes unseen in a century,comprehensive containment and suppression of China in the name of strategic competition has become a crossparty consensus in the United States,with the Republican Trump administration initiating the process of containing and suppressing China and the Democratic Biden administration continuing and developing such a strategy.In the process of implementing this strategy,there are some diff erences in the goals and means of the two American administrations.The Trump administration was trying to“crush China”with the super strength of the United States,with more extreme and tougher means,being more unilateralist and even going so far as to launch a“new Cold War”against China.The Biden administration,on the other hand,emphasizes long-term competition with China,and focuses on“managing competition”while suppressing China,accustomed to being double-handed and using both carrot and stick.When it comes to addressing global challenges,the Republican Party completely lacks the will to cooperate with China,while the Democratic Party has a certain need for cooperation and action.

Application of Information Technology in Institutions and Challenges of Human Resources-Case Study: Administration of the Municipality of Ferizaj

This study aims to investigate how information technology is applied in the administration of the municipality of Ferizaj and what are the challenges with human resources, the work was carried out through a case study in the municipality. This paper highlights that the use of information technology provides higher efficiency for the performance of daily work in the municipality, thus also the provision of better services to citizens. However, the level of use of information technology in the Municipality of Ferizaj leaves much to be desired in terms of efficiency because a significant number of employees have not attended adequate training for the effective and efficient use of various IT applications and have not are still adapted to the digital environment in the municipality. Therefore, the recommendation derived from this paper is that the information technology environment in the municipality of Ferizaj needs to be improved by providing staff with adequate qualifications, while for those who are currently engaged in the municipality and who do not have adequate qualifications, training should be provided in a way that all users of IT applications are fully integrated into the digitized environment in order to be effective and efficient in providing services to citizens. This simultaneously gives the municipal staff job security and motivation for better services for citizens. Also, information technology enables a better control over the activity of the municipality because every action is recorded as data which can then be used to analyze the performance of the municipality.

行政法典化的渐进主义路径

行政法典是规范行政权和保护公民合法权益的最高级别的规范形式。法典化反映的是编纂法典的动态的发展趋势,其表现形式可以是多元化的,构造可以是多层次的,发展可以是渐进的、多阶段的。行政法典的理论构想包含行政法总则、行政基本法、行政程序法三种模式。行政法典化受行政法体系、立法成果、行政法理论以及文化等因素影响。从目标定位来看,要降低理想型、高级形态行政法典的预期,采取一种更为务实的局部性、适应性、渐进性、阶段性为特征的适度法典化的路径。在功能主义与渐进主义的双重视角下,把行政程序法作为行政基本法典的实现路径,更具有可行性和操作性。

非正式治理的制度化运作:管区制与乡镇治理现代化的路径选择

管区作为一种非正式的组织设置,在乡镇与村级治理单元之间建构出实体性质的中间结构,具有低成本、非正式性和制度稳定性等特点,成为乡镇政权的延伸。管区设置虽然增加了乡镇内部的“委托—代理”层级,但通过行政体制上的形式化设置和实践中的非正式运作,具有了超越科层体制约束的优势,借助激励动员和组织重构实现了有效治理。管区借助乡镇内部人力资源的重新配置,在不变体制的情况下进行机制创新,实现了非正式治理的制度化运作,匹配了当前乡村社会转型和治理转型的需求,成为当前强国家治理背景下探索乡镇治理现代化的一条可行路径。

Status, Transition, and Impact of the Yoon Suk-yeol Administration’s Trade Policy with China

China is Korea’s main trade partner in East Asia and one of its key economic and trade partners worldwide.The two countries have complementary industrial structure and a long history of trade exchanges.However,against the backdrop of a return to global trade protectionism and the politicization of international affairs with Yoon Suk-yeol coming to power,South Korea has undertaken a strong trade shift toward the United States(US),triggering a change in the pattern of economic cooperation in East Asia and challenging the regional trade structure.A review of the trade policy agenda of the Yoon Suk-yeol administration toward the US and China,along with a comparative review of Korea’s foreign trade stance under Moon Jae-in,allows for an analysis of the turnaround and characteristics of Yoon’s trade policy toward China during his tenure.The implications for global trade governance and regional security are further analyzed with an aim of finding a Nash equilibrium in trade cooperation among East Asian countries.

数字政府视阈下的算法行政:兴起、风险与法治纠偏

随着数字政府建设目标的确立,算法技术嵌入行政成为一种必然趋势,但是算法在促进行政的同时,也带来了法治价值失序的隐忧。算法基于海量数据运算配置社会资源,辅助甚至独立作出行政行为,或许将会成为行政权行使的中枢性力量。但是,过度依赖算法可能导致强调技术理性而忽视价值理性。算法技术本身所带的内生性风险与算法应用中潜在的风险,暗含着行政权力的“技术延伸”和公民权利被侵蚀的隐患,算法行政遭受合法性和合理性的诘难,数字政府建设与法治政府建设面临耦合困境。为防范算法行政异化风险,政府的数字化必须与法治化同步建设,警惕技术理性凌驾于价值理性之上的观念,并从算法的创制、适用以及事后追责的各阶段构建起算法行政的合法性约束机制,避免“权力—权利”格局的失衡,从而促进政府数字化建设和法治化建设的深度融合。

跨省横向府际应急协同机制的实践样态及制度保障

突破省域边界的突发事件具有复杂性、不确定性与突发性,灾害后果严重。实践中,各省级政府通过签订应急协同协议、新设应急协同组织、开展联席会议与会商应对跨省突发事件,形成了多元化的应急协同机制,契合中国特色应急管理制度的改革方向。但是,相关机制不仅面临合法性质疑,还存在效力薄弱、协同动力不足和未突破区域壁垒的弊病,需要完善相关合法性保障与实效保障。协同机制具备实质合宪性,《中华人民共和国地方各级人民代表大会和地方各级人民政府组织法》赋予其组织法依据,一些仅供协调而未涉及职权调整的协同机制不违反职权法定原则与组织法定原则,具备合法性。然而,应对跨省突发事件需要整合各省政府部门职权以形成区域性应急行政权,该权力源自政府的行政授权,可由《中华人民共和国突发事件应对法》完善相关法律依据。协同机制的实效保障需要多路并进:在协同协议层面,应当进一步提升协议的法律效力与可操作性;在协同组织层面,需要健全应急协同组织及其内部结构;在协同信息层面,完善应急协同信息平台建设有助于收集、共享常态化信息与突发事件预警和处置信息;在协同动力层面,可以通过夯实协同观念基础与信任基础、增加协同净收益和加强中央政府的高位推动增强协同动力。

城市行政区划优化调整的法治逻辑与实践构想

城市是我国经济、政治、文化、社会等方面活动的中心,城市治理现代化是实现国家治理现代化和中国式现代化的重要环节。改革开放以来,政策调控所形成的城市格局已经不能适应当下的城市发展进程以及未来的国家发展战略定位,部分城市的行政区划设置并不完全符合宪法的具体规范与法治化要求。为了满足现代化的城市治理需求,城市行政区划优化调整的法治化已成必然。当前城市行政区划在区划建制、行政区域划分、行政层级设置等方面存在的规范问题,应当以《宪法》为根本依据、以法律为具体支撑,在法治轨道上进行优化调整的实践构想,以期实现行政区划制度体系的完善与城市治理的高效,更好发挥城市的辐射带动作用,实现区域协调和高质量发展。

政府合同概念的体系化重构

现有政府合同管理规范对政府合同的内涵和外延进行了界定,但学理意义上的概念构造尚未完成,“政府合同=行政协议+缔结主体一方为行政机关的民事合同”之结论存在缺陷。通过把合同还原为通用于各部门法的中性工具,将政府合同的研究视角从救济前移至行政过程,政府合同的识别标准被调整为“行政机关与任何主体订立的合同均为政府合同”。以行政任务为出发点,可将政府合同区分为公务型政府合同和管理型政府合同,公务型政府合同可被进一步区分为内部公务型政府合同与外部公务型政府合同。以救济途径为落脚点,可以将政府合同区分为行政协定与非行政协定,非行政协定可被进一步区分为行政协议、民事合同、磋商性文件和劳动人事协议,其中,民事合同和行政协议属于狭义政府合同。将两条基于不同场景的体系化路径进行对接与融合,有助于形成对政府合同概念相对立体的认知,动态还原政府合同概念的全貌。

论行政复议的适当性审查

合法性审查、适当性审查是行政复议机关审查被申请行政行为的两个审查标准。适当性审查与行政诉讼合理性审查表述不同但内容一致。合法性审查是形式合法性审查,适当性审查是实质合法性审查,因此,适当性审查与合法性审查构成了一种从“从形式违法到实质违法”的双阶审查方法。在形式合法性已经确认的前提下,针对被申请行政行为的内容,行政复议机关可以从合目的性、结果可接受性和利益权衡三个面向作适当性审查。
