To investigate the influence of high molecular weight polyethylene (HMWP) on the viability of osteoblasts and new bone formation in the process of fracture healing, the osteoblasts derived from adult human bone marrow were cultured in HMWP maceration extract and normal culture medium. The viability of the osteoblasts was measured by MTT assay, and the(More)
BACKGROUND This study is aimed at evaluating the operation techniques and clinical significance of free flap transplantation combined with skin grafting and vacuum sealing drainage (VSD) in repairing severe traumatic extensive circumferential or semi-circumferential soft-tissue defects of the lower leg. MATERIAL AND METHODS Thirty patients with severe(More)
PURPOSE The aim of the study is to evaluate the surgical technique and clinical significance of the sequential therapy of vacuum sealing drainage (VSD) and free-flap transplantation for children with extensive soft-tissue defects below the knee in the extremities. METHODS Twenty-two children (aged from 3 to 10 years) received sequential therapy of VSD and(More)
BACKGROUND Physiological loading is widely believed to be beneficial in maintaining skeletal integrity by stimulating new bone formation through increases in osteoblastic activity and concomitant decreases in osteoclastic activity. However, excessive or nonphysiological loading is associated with bone injuries, including stress fractures and osteoporotic(More)
OBJECTIVE To review the research progress on the three-dimensional (3D) reconstruction and visualization of peripheral nerve. METHODS Literature about the research on the 3D reconstruction and visualization of peripheral nerve both at home and abroad were extensively reviewed and thoroughly analyzed. RESULTS The application of 3D reconstruction and(More)
SUMMARY Since arthroplasty, prosthetic replacement and non-vascularised articulation autografting do not normally produce very satisfactory results for ankylosis of metacarpophalangeal and interphalangeal joints, the authors performed reconstruction of phalangeal articulations of the hand using vascularised phalangeal articulations of the foot in 11(More)
OBJECTIVE To explore the surgical technique and clinical value of treatment for posttraumatic large circular soft tissue defect in the lower extremities using a combination of posterior tibial vascular bridge flap in the unaffected leg and skin graft covered by vacuum sealing drainage (VSD). METHODS From January 2008 to June 2010, 11 cases with(More)
OBJECTIVE To investigate the feasibility of inducing in vitro mesenchymal stem cells (MSCs) derived from adult human bone marrow differentiate into osteoblasts and potential applicability of the MSCs as the seed cells in tissue engineering. METHODS Adult human bone marrow was collected from the healthy adult volunteers to obtain the MSCs, which, after in(More)
OBJECTIVE To study whether tissue engineered bone can repair the large segment bone defect of large animal or not. To observe what character the fascia flap played during the osteanagenesis and revascularization process of tissue engineered bone. METHODS 9 Chinese goats were made 2 cm left tibia diaphyseal defect. The repairing effect of the defects was(More)
OBJECTIVE To observe the role of green fluorescent protein (GFP) in tracing rhesus bone marrow stromal cells (rBMSCs) during tissue-engineered bone formation in vivo. METHODS Ad5.CMV-GFP was amplified by infecting QBI-293A cells, and the bone marrow was harvested from the ilium of adult male rhesus to obtain rBMSCs, which were cultured and passaged in(More)
