Injectable calcium sulphate/phosphate cement (CSPC) with degradable characteristic was developed by introduction of calcium sulphate (CS) into calcium phosphate cement (CPC). The setting time, compressive strength, composition, degradation, cells and tissue responses to the CSPC were investigated. The results show that the injectable CSPC with optimum L/P(More)
Nanoporous bioglass containing silver (n-BGS) was fabricated using the sol-gel method, with cetyltrimethyl ammonium bromide as template. The results showed that n-BGS with nanoporous structure had a surface area of 467 m(2)/g and a pore size of around 6 nm, and exhibited a significantly higher water absorption rate compared with BGS without nanopores. The(More)
Fluorapatite with low solubility is a promising biomaterial due to its structure, which is similar to hydroxyapatite. In this study a bioactive composite of nanofluorapatite (n-FA) and polyamide 12 (PA12) was fabricated. The results revealed that the mechanical properties (such as compressive strength and elastic modulus), hydrophilicity, and antibacterial(More)
OBJECTIVE To analyze the un-healing cause and management after operation of thoracolumbar tuberculosis. METHODS From January 2008 to December 2011, the data of 12 patients with postoperative un-healing thoracolumbar tuberculosis were retrospectively analyzed. There were 5 males and 7 females, with an average age of 51.3 years old (ranged, 42 to 65). All(More)
