　　Purpose: This study aimed to construct osteogenic and angiogenic bi-lineage differentiated adipose tissue-derived stem cells(ADSCs)sheet-implant complex and investigate its biological characteristics.Method: The osteogenic and angiogenic bi-lineage differentiated ADSCs sheet(Group A)and osteogenic differentiated ADSCs sheet(Group B)were warped on traditional pure Ti implant separately and the obtained complexes were cultured in vitro for 4weeks.ALP activity and the expression of BMP-2 and VEGF of the complex surface were investigated after 1d,14d and 28d of culture.Then the complexes were implanted into subcutaneously pockets of severe combined immunodeficiency mice.After 8 weeks' transplantation,Micro CT assay was conducted in vivo.Then recover the complex,strip the tissue around it and stain with HE to observe its microstructure.

氧化羟基锡酸铁的制备及其包覆高岭土在PVC中的阻燃应用

聚氯乙烯(PVC)是应用范围最广的通用型热塑性材料之一。但是由于在成型过程中会添加大量的易燃增塑剂,使其阻燃性大大降低,而且在燃烧过程中会产生大量的有毒有害气体,对人们的生命和自然环境造成了极大的危害。因此,对PVC进行阻燃抑烟研究具有重要意义。本文主要制备了氧化羟基锡酸铁(FeSnO(OH)_5,ITOH)及其包覆煅烧高岭土(KLN@ITOH)复合材料,并通过X射线衍射(XRD)、扫描电子显微镜
