Desmoplastic fibroma is a rare, benign soft‑tissue tumor composed of spindled and stellate‑shaped cells that are embedded in a dense collagenous stroma. Clinically, desmo-plastic fibroma presents as a firm, mobile, slow‑growing mass that is located in the subcutaneous tissue or near the deep aspect of the skeletal muscles. The present study describes the(More)
BACKGROUND The feasibility of distal femur epiphysis preservation through epiphyseal distraction by external fixator in childhood osteosarcoma was explored. METHODS Between July 2007 and May 2011, 10 children who were suffering from distal femur osteosarcoma received epiphyseal distraction by external fixator, combined with tumor resection and repair with(More)
In this study, the effects of surgical removal of malignant metaphyseal bone tumors with epiphysis preservation and knee arthroplasty were analyzed. A total of 15 patients with malignant metaphyseal bone tumors were investigated. Six of these patients underwent epiphyseal preservation surgery with preoperative physeal distraction, termed the physeal(More)
OBJECTIVE To investigate the effect of tissue engineering nerve on repair of rat sciatic nerve defect. METHODS Forty-five rats with defective sciatic nerve were randomly divided into three groups. Rats in group A were repaired by acellular nerve grafts only. Rats in group B were repaired by tissue engineering nerve. In group C, rats were repaired by(More)
INTRODUCTION The aim of the study was to explore an effective method to induce adipose-derived stem cells (ADSCs) to differentiate into Schwann-like cells in vitro. MATERIAL AND METHODS Reagents were applied in two different ways (Dezawa inducing method and modified inducing method) in which inducers including β-mercaptoethanol (β-ME), all-trans-retinoic(More)
