Burns & Trauma 2017年第1期5卷 1-8页

Burn contractures produce restrictions in motion and unacceptable aesthetic results, frequently with persistent wounds. Proper planning and tissue selection are essential to minimize donor site morbidity optimizing outcomes. The principle of burn reconstructive surgery requires that the defects after release should be replaced with donor tissues which have matching texture and color as well as enough pliability. Autologous skin grafting or flap surgeries meet these criteria to replace scar tissues and resurface the subsequent to post-released scar defects. Despite the benefits, the use of flaps is often limited in burn patients for many reasons. If a surgeon intends to release completely and reconstruct in one-stage operation, a large defect may result in large donor site morbidity, necessitating flap surgery including free flap surgery. A lot of different methods and procedures are available for resurfacing the defects, and these are reviewed. In this article, algorithms for the release of burn contractures and reconstructive methods are presented. These treatment algorithms should aid in achieving significant improvement in both joint motions and aesthetic deformities.

Magnetically recyclable Au/Co/Fe core-shell nanoparticles （NPs） have been successfully synthesized via a one-step in situ procedure. Transmission electron microscope （TEM）, energy dispersive X-ray spectroscopic （EDS）, and electron energy-loss spectroscopic （EELS） measurements revealed that the trimetallic Au/Co/Fe NPs have a triple-layered core-shell structure composed of a Au core, a Co-rich inter-layer, and a Fe-rich shell. The Au/Co/Fe core-shell NPs exhibit much higher catalytic activities for hydrolytic dehydrogenation of ammonia borane （NHBBH3, AB） than the monometallic （Au, Co, Fe） or bimetallic （AuCo, AuFe, CoFe） counterparts.
