发展简单、高效、可控的方法来制备中空介孔微球是介孔材料领域的研究热点.本工作结合嵌段共聚物的三维受限自组装(3D-CSA)和自模板碳化策略,建立了一种构筑中空介孔微球的新方法.首先,采用乳液-溶剂挥发法实现嵌段共聚物与全氟辛烷(PFO)在3D受限空间的分级组装,获得了核-壳结构微球,其中壳层由微相分离的嵌段共聚物构成.然后,在壳层的连续相选择性地复合氧化硅,既实现了无机框架的负载,又实现了对连续相聚合物链选择性交联.对复合微球进行煅烧处理后,实现了壳层连续相聚合物的选择性碳化,获得了中空介孔氧化硅/碳复合微球.本研究系统地阐述了核-壳型分级结构微球的形成机理和必备条件,研究了氧化硅前驱体添加量和嵌段共聚物分子量对中空介孔氧化硅/碳复合微球形貌的影响,为制备中空介孔微球材料提供了一种简便、可控的方法.

Since the release of the first version of the 5th Generation Mobile Networks (5G) standard， Release-15 (Rel-15)， in June 2018， the 3rd Generation Partnership Project (3GPP) made significant efforts in the field of indoor and outdoor wireless positioning. Notably， Release-16 augmented support for enhanced mobile broadband (eMBB) and ultra-reliable low-latency communication (uRLLC)， particularly within complex indoor settings. To further meet the diverse application needs of positioning scenarios， the 3GPP standards for Release-17 and Release-18 propose new enhancement measures to continuously provide more accurate positioning services. In this paper， the scholarly discourse on 5G positioning was critically examined， providing a systematic review of the 5G positioning standards as delineated in 3GPP's Release-16 and Release-17， and was extended the discussion to the anticipated enhancements in 5G Release-18， along with their underlying motivations. Through these discussions， this article not only a comprehensive perspective on the current development of 5G positioning technology was provided but also was offered forward-looking analysis and predictions for the evolution of positioning technology in the upcoming 3GPP Release-19 phase. Additionally， it serves as a reference for researchers interested in understanding the development of positioning within the standard framework in the field of 5G indoor positioning， which holds significant meaning for promoting research and application of 5G positioning technology.

目的探讨miR-206在香烟烟雾提取物(CSE)诱导人肺微血管内皮细胞(HPMECs)凋亡中的分子作用机制。方法实时定量PCR检测相关基因的表达水平;Western blot检测相关蛋白的表达水平;流式细胞技术检测细胞凋亡;萤光素酶实验验证miR-206与下游基因的结合位点。结果不同浓度的CSE (0.5%～5.0%)处理能够促进HPMECs凋亡的同时增加miR-206的表达水平(P<0.05)。MiR-206过表达促进HPMECs的凋亡,同时提高cleaved caspase-3和caspase-9蛋白水平(P<0.05);而miR-206低表达可以抑制CSE引起的HPMECs凋亡以及凋亡相关蛋白(cleaved caspase-3和caspase-9)表达的上调(P<0.05)。生物信息学分析以及萤光素酶实验结果证实miR-206可以通过作用于notch3 3'非翻译区从而抑制notch3的表达。进一步的营救实验发现,notch3过表达可以拮抗miR-206引起的HPMEC凋亡。结论 MiR-206在CSE处理的HPMECs中表达上调,miR-206低表达对CSE引起的凋亡起到抑制作用,这种作用可能是通过靶向调控notch3来实现的。
