In this study, we aimed to prepare a novel type of microbubble (MB), protamine cationic nanobubble (NB), to provide a new vector for tumor gene therapy. We prepared cationic NBs with protamine and other lipid components using mechanical oscillation. The protamine cationic NBs had a mean diameter of 521.2 ± 37.57 nm, a zeta potential of +18.5 mV, and a(More)
OBJECTIVE To observe and compare the effects of using mGTR and venous autografts to repair the defect of facial nerve in rabbits. METHODS mGTR and venous autografts were performed on three groups of rabbits. Then physical and histological examinations were carried out to get the results of these two repair methods. RESULTS Both the two methods can(More)

The right sides were selected as e-PTFE containing nervous homogenates group, 8 mm defect of facial never were made, then the defect was bridged(More)
OBJECTIVE To establish a three-dimension finite element model of mandible with two kinds of dental implant and to study the stress of implant-bone interface. METHODS Measuring the data of the components of the dental implant and using spiral CT image reconstruction technique to scan the cross section of the mandible. Three-dimension finite element(More)
PURPOSE To evaluate the clinical results of implant denture in the anterior maxilla over 5 years. METHODS From January 2002 to December 2006, two hundred and thirty-four patients with 354 dental implants were followed up for 7-62 months. The results were evaluated by X-ray, clinical examination and patient satisfaction investigation. The 5 year cumulative(More)
