大豆蛋白纤维以其具有的许多优异性能，如吸湿性能、透气性能、保暖性能和可纺性能都与毛、麻、丝、棉等天然纤维相仿，而成本又远低于后者，其主要原料是来自于榨过油的大豆粕，原料数量大、可再生。生产过程环保。本文着重介绍大豆蛋白纤维的组成、特性、生产与发展。     

纳米TiO2的分散及其在织物上整理工艺的研究

研究了几种常用分散剂及其复配分散剂对TiO2水悬浮液中纳米粉体的分散稳定性能，得出了高聚物大分子与小分子电解质复配的分散剂对纳米TiO2有较好的分散效果，并对复配分散剂的用量、悬浮液pH值、超声波振荡分散时间对悬浮液稳定性的影响作了研究．确定了试验的分散工艺，分散后的悬浮液静置1h后，分散体系的透过率为4.8％，比不加分散剂体系的透过率下降了51．5％．讨论了3种整理工艺整理织物上纳米TiO2粒子分布的均匀性和抗紫外性能，认为二浸二轧法具有较好的综合效果，既能达到均匀的整理效果，对织物损伤也较小．     

Encapsulation of Nano-Bortezomib in Apoptotic Stem Cell-Derived Vesicles for the Treatment of Multiple Myeloma

Extracellular vesicles (EVs) are lipid bilayer nanovesicles released from living or apoptotic cells that can transport DNA, RNA, protein, and lipid cargo. EVs play critical roles in cell–cell communication and tissue homeostasis, and have numerous therapeutic uses including serving as carriers for nanodrug delivery. There are multiple ways to load EVs with nanodrugs, such as electroporation, extrusion, and ultrasound. However, these approaches may have limited drug-loading rates, poor EV membrane stability, and high cost for large-scale production. Here, it is shown that apoptotic mesenchymal stem cells (MSCs) can encapsulate exogenously added nanoparticles into apoptotic vesicles (apoVs) with a high loading efficiency. When nano-bortezomib is incorporated into apoVs in culture-expanded apoptotic MSCs, nano-bortezomib-apoVs show a synergistic combination effect of bortezomib and apoVs to ameliorate multiple myeloma (MM) in a mouse model, along with significantly reduced side effects of nano-bortezomib. Moreover, it is shown that Rab7 regulates the nanoparticle encapsulation efficiency in apoptotic MSCs and that activation of Rab7 can increase nanoparticle-apoV production. In this study, a previously unknown mechanism to naturally synthesize nano-bortezomib-apoVs to improve MM therapy is revealed.
