RNA binding protein Lin28A promotes osteocarcinoma cells progression by associating with the long noncoding RNA MALAT1.

Objectives: To explore the effects of Lin28A on progression of osteocarcinoma (OS) cells.

Results: Lin28A mRNA and protein expressions were significantly increased in OS tissues compared with that in normal adjacent tissues. Expressions of Lin28A and long noncoding RNA MALAT1 were positively correlated.

[Comparison between external fixator and DVR system for the treatment of AO type C distal radial fractures].

Objective: To compare the clinical effects of external fixator versus DVR system for the treatment of AO type C distal radius fractures.

Methods: The clinical data of 52 patients with type C distal radial fractures treated with external fixator or DVR system respectively from January 2009 to December 2013 were analyzed retrospectively. In DVR system group, 31 patients were treated by open reduction and internal fixation with DVR system, involved 11 males and 20 females, with an average age of(47.

Adhesion, proliferation and differentiation of osteoblasts on zirconia films prepared by cathodic arc deposition.

Zirconia films were prepared on titanium by cathodic arc deposition technique. The surface topography and element composition of the films were characterized by scanning electron microscopy and X-ray photoelectron spectroscopy, respectively. Osteoblast-like MG63 cells were cultured on the surface of the zirconia films in vitro, and cell behaviour was investigated, with titanium as control.

Adhesion of osteoblast-like cell on silicon-doped TiO2 film prepared by cathodic arc deposition.

Silicon-doped TiO2 (Si-TiO2) and pure TiO2 films were deposited on titanium substrates by cathodic arc deposition technique. The surface characteristics of the films, such as surface topography, elemental composition and wettability, were studied. About 4.

Proliferation and differentiation of osteoblastic cells on silicon-doped TiO(2) film deposited by cathodic arc.

This study aimed at the proliferation and differentiation of osteoblastic cells on silicon-doped TiO(2) and pure TiO(2) films prepared by cathodic arc deposition. The films were examined by X-ray photo-electron spectroscopy, which showed that silicon was successfully doped into the Si-TiO(2) film. Meanwhile, no significant difference was found between the surface morphology of silicon-doped TiO(2) and pure TiO(2) films.

Biological behavior of osteoblast-like cells on titania and zirconia films deposited by cathodic arc deposition.

Cathodic arc deposition technique was used to deposit zirconia (ZrO(2)) films and titania (TiO(2)) films on titanium (Ti) disks respectively. The surface topography was characterized by scanning electron microscopy and atomic force microscopy. The element composition of the films was detected by X-ray photoelectron spectroscopy.

Predictive potential of glutathione S-transferase polymorphisms for prognosis of osteosarcoma patients on chemotherapy.

Objective: To evaluate the predictive value of glutathione S-transferase (GST) gene polymorphisms for the prognosis of osteosarcoma patients receiving chemotherapy.

Methods: A total of 159 patients were included in our study between January 2005 and December 2007., with follow-up until January 2012.
