Osteosarcoma is the most common malignant bone tumor, and the prognosis of patients with osteosarcoma is still unsatisfactory with low survival rates. There are many studies assessing the prognostic role of upregulated p53 in patients presenting osteosarcoma, and there is no consistent finding. To summarize the existing evidence about whether the presence(More)
OBJECTIVE To document the vascular anatomy of the distally based superficial sural artery flap and to study the vascular anastomoses between the superficial sural artery and the septocutaneous perforators of the peroneal artery. METHODS Ten fresh human cadavers were injected with lead oxide, gelatin and water. Twenty lags were then dissected and an(More)
BACKGROUND Capsular contracture has become the most common complication associated with breast implant. Transforming growth factor-beta (TGF-β) is well known for a prominent role in fibrotic diseases. Due to the critical role of TGF-β in pathogenesis of capsular formation, we utilized thermosensitive C/GP hydrogel to controlled release of TGF-β receptor(More)
BACKGROUND For cardiovascular tissue engineering, acellularized biomaterials from pig have been widely investigated. Our purpose was to study mechanical properties and biocompatibility of decellularized aorta of fetal pigs (DAFP) to determine its potential as scaffold for small diameter tissue engineered vascular graft. METHODS Descending aorta of fetal(More)
Respiratory syncytial virus (RSV) is the major cause of lower respiratory tract infection in infants and young children. Although several experimental RSV vaccines are under investigation, immuno therapy is the only treatment currently available. In assessing the immunogenicity of various vaccine formulations, a plaque reduction neutralization assay for the(More)
OBJECTIVE To explore the influence of rosa roxburghii tratt preparation on immune function of arseniasis patients caused by burning coal. METHODS According to the diagnosis standard for endemic arseniasis(WS/T 211-2001), 62 cases of arseniasis patients who resided in endemic arseniasis area in Guizhou province were selected and divided stratified randomly(More)
OBJECTIVE To observe the mechanical properties of the prefabricated connective tissue tube as blood vessel substitute and its changes after implantation at the femoral artery. METHODS The acellular matrix tube of 8-12 cm in length with a silicone rod inside it was implanted into dog peritoneal cavity. 3 weeks later, a new formed tube around the silicone(More)
OBJECTIVE The objective of this anatomic study was to investigate the intramuscular neurovascular configuration and to evaluate whether the muscle could be split into two functional units in transplantation. METHODS Ten fresh cadavers and ten preserved cadavers were used in the study. A mixture of lead oxide, gelatin and water was injected to the femoral(More)
OBJECTIVE To investigate the reconstruction of skin defect at frontal and temporal hair line. METHODS 5 cases with skin defect at frontal and temporal hair line were treated with mastoid fasciocutaneous island flap pedicled with parietal branch of superficial temporal artery. RESULTS All the flaps survived completely. Hair grew up 5 - 7 days after(More)
OBJECTIVE To investigate a new technique for functional treatment of chronic facial paralysis. METHODS Based on anatomy of intramuscular neurovascular structure in the rectus femoris muscle, 7 consecutive patients with facial paralysis were treated by using a technique of microsurgically free-transferring neurovascular rectus femoris muscle segment to the(More)
