Poly(1,8-octanediol citrate) (POC) is a recently developed biodegradable crosslinked elastomer that possesses good cytocompatibility and matchable mechanical properties to soft tissues. However, the thermosetting characteristic reveals a big challenge to manufacture its porous scaffold. Herein, POC elastomer was electrospun into fiber mat using(More)
To explore the repairing effect of combination of adipose stem cells (ASCs) and composite scaffolds on CWR, the electrospun Poly 1, 8-octanediol-co-citric acid (POC)-poly-L-lactide acid (PLA) composite scaffolds were prepared, followed by in vitro and in vivo biocompatibility evaluation of the scaffolds. Afterwards, ASCs were seeded on POC-PLA to construct(More)
Electrospinning and electric stimulation (ES) are both promising methods to support neuron adhesion and guide extension of neurons for nerve regeneration. Concurrently, all studies focus on either electrospinning for conduits material or ES in vitro study to accelerate nerve regeneration; few work on the combined use of these two strategies or ES in vivo(More)
Objective: The study was to explore the clinical characteristics and therapies of the spinal extradural arachnoid cyst in neck and thoracolumbar segment. Methods: Retrospective analysis was conducted on 15 cases with spinal extradural arachnoid cyst in the neck and thoracolumbar segment who had obvious symptoms and were treated in our department within the(More)
Fluorescence in situ Hybridization (FISH) was used to investigate whether the chromosome of the fetus prenatally diagnosed as pyelectasis was normal or not. Amniotic fluid was taken from the pregnant woman whose fetus was detected with pyelectasia by prenatal examination. The chromosome of the amniotic fluid cell without culture was examined with FISH. The(More)
Early OC fixation techniques using cable fixation had a high rate of failure. For this reason, they were supplanted with rigid posterior fixation systems involving plates and screws or rods and screws because these have higher rates of fusion and provide better biomechanical stability (1,4,6,8,13,19,20). However, there is still no currently available system(More)
