对于“远程教育”这一概念,不同国家、不同时期、不同背景的学者有着不同的认识。通过考证“远程教育”一词的来源,梳理国内外学者对远程教育概念的认识,进一步揭示远程教育的内涵和外延,有利于深刻认识远程教育。远程教育是教育者和学习者在时间和空间相对分离的情境下,基于媒体,依赖资源,凭借技术,实现教学交互,以促进个人发展、实现终身学习为目的的一种面向社会全员开展的教育综合活动。远程教育与函授教育、电化教育、开放教育、成人教育、继续教育、社区教育、终身教育等概念既有联系,又有区别,具有师生时空的分离性、教育理念的开放性、教育对象的主动性、教育媒体的多样性、教学模式的灵活性等特征。

在实现共同富裕的新进程中,我国农村贫困治理已由治理绝对贫困及其代际传递向治理相对贫困及其代际传递转移。继续教育作为缩小社会鸿沟、实现社会公平的有效手段,在阻断农村相对贫困代际传递过程中具有重要作用。作为“从摇篮到坟墓”... 详细信息

在实现共同富裕的新进程中,我国农村贫困治理已由治理绝对贫困及其代际传递向治理相对贫困及其代际传递转移。继续教育作为缩小社会鸿沟、实现社会公平的有效手段,在阻断农村相对贫困代际传递过程中具有重要作用。作为“从摇篮到坟墓”的福利国家,英国的贫困治理理论及实践都走在了世界前列,从英国经验看中国道路,对我国具有积极的现实意义。研究发现:在经历了初步发展时期、失衡探索时期、全面推进时期之后,英国继续教育阻断农村相对贫困代际传递呈现出“代内与代际”“社会共同善与个体权利平衡”“济贫与济身”兼顾的特点。借鉴英经验,我国继续教育应从以下方面助力阻断农村相对贫困代际传递:以一代发展推进二代流动,阻断相对贫困代际传递;以教育公平促进社会公平,形成多元一体合力;以提高能力实现个人自由,激发公民个体意识。

The reform stems from honesty and determination. 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.

目的探究C1q/肿瘤坏死因子相关蛋白6(C1q/tumor necrosis factor related protein 6,CTRP6)在槲皮素(quercetin,Que)抑制急性心肌梗死(acute myocardial infarction,AMI)后大鼠心肌细胞焦亡中的作用及机制。方法采用冠状动脉左前降支结扎法建立AMI大鼠模型。首先,将实验分为假手术组(Sham)、AMI组、槲皮素低剂量组(Que-L,25 mg·kg^(-1))、槲皮素高剂量组(Que-H,100 mg·kg^(-1))、福辛普利钠片组(fosinopril,4 mg·kg^(-1)),每组各10只。各组大鼠按照对应的药物剂量或是生理盐水灌胃,1次/d,连续14 d。多普勒超声检测心功能变化,观察大鼠心肌组织病理学变化,Western blot检测焦亡相关蛋白和CTRP6表达。通过以上实验指标检测筛选得出Que最佳给药剂量。随后,将实验分为Sham、AMI、Que(100 mg·kg^(-1))、Que+si-NC组、Que+si-CTRP6,每组各10只。干预14 d后,检测心肌梗死、心肌损伤指标、细胞焦亡、CTRP6及PI3K/Akt通路蛋白表达。结果与Sham组相比,AMI组大鼠LVEDV、LVESV明显增加,EF、FS明显降低(P<0.05),心肌组织出现明显病理损伤,纤维化程度增加,心肌梗死面积增加,LDH、CK-MB、cTnI水平,TUNEL阳性细胞比率升高,NLRP3、cleaved caspase-1、GSDMD-N、IL-1β、IL-18表达增加,CTRP6表达,p-PI3K/PI3K、p-Akt/Akt比值降低(均P<0.05)。与AMI组相比,Que-L和Que-H大鼠心功能指标以及心肌组织病理损伤程度减轻,心肌梗死面积降低,LDH、CK-MB、cTnI水平,TUNEL阳性率降低( P <0.05),细胞焦亡相关蛋白表达降低,CTRP6及PI3K/Akt通路蛋白表达增加( P <0.05),且呈剂量相关性。与Que组相比,Que+si-CTRP6组大鼠上述指标变化均得到明显逆转。结论 Que能够抑制心肌细胞焦亡,改善AMI大鼠心肌梗死,其机制与上调CTRP6表达,促进PI3K/Akt信号通路活化相关。

As a class of functional crystalline porous materials, metal-organic frameworks(MOFs) gained rapid development in the past three decades and a large number of MOFs with ordered structures, high surface areas, and functionalized channels have been investigated. MOFs and MOF-derived/composite materials show great potential in many application fields. In this review, we discussed the main applications of MOFs and MOF-derived/composite materials in small molecule storage, separation, luminescence, sensing, multitype catalysis, and energy storage. In addition, challenges and problems in the future research of MOFsrelated fields are also discussed.
