Platinum-based chemotherapy is used for non-small cell lung cancer (NSCLC).However,it has side effects and minimum efficacy against lung cancer metastasis.In this study,platinum-curcumin complexes were loaded into pH and redox dual-responsive nanoparticles (denoted as Pt-CUR@PSPPN) to facilitate intracellular release and synergistic anti-cancer effects.Pt-CUR@PSPPN was prepared by a nano-precipitation method and had a diameter of ~ 100 nm.The nanoparticles showed increased anticancer effects both in vivo and in vitro.In addition,Pt-CUR@PSPPN blocked PI3K/AKT signal transduction pathway and inhibited MMP2 and VEGFR2,resulting in enhanced anti-metastatic activity.Furthermore,reduced side effects were also observed.In conclusion,Pt-CUR@PSPPN provided a novel and attractive therapeutic strategy for NSCLC.

杂交棉具有产量高、很强的个体生长优势等特点,杂交棉的种植使新疆棉花单产水平有了进一步提高,而新疆一些棉区无霜期短、热量资源有限,严重制约了棉花杂种优势的发挥,且新疆棉区矮密早高产栽培技术体系造成棉花用种量大,大幅增加了杂交棉的种植成本,影响了杂交棉生产的发展。开展杂交棉移栽稀植试验,以避开不利的气候条件影响,充分发挥杂交棉的增产优势;通过杂交棉稀播试验,以减少用种量,充分发挥杂交棉的个体增产优势。
