OBJECTIVETo evaluate the feasibility of using iron oxide nanoparticles as gene vector and the effect of magnetic field on efficiency of transfection.
METHODSIron oxide nanoparticles were prepared by alkaline precipitation of divalent and trivalent iron chloride. The surface of iron oxide nanoparticles was modified by self-assembled poly-L-lysine to form particle complexes (IONP-PLL). Transfection was determined by delivering reporter gene, PGL2-control encoding luciferase, to different cell lines using IONP-PLL as vector. The effect of magnetic field on efficiency of transfection was determined using Nd-Fe-B permanent magnet.
RESULTSForeign gene could be delivered to various cell lines by IONP-PLL and expressed with high efficiency, but the transfection efficiency and time course varied in the different cell lines studied. Magnetic field could enhance the efficiency of transfection by 5 - 10 fold.
CONCLUSIONIONP-PLL can be used as a novel non-viral gene vector in vitro, which offers a basis for gene delivery in vivo.

OBJECTIVETo investigate the effects of neuropeptide Y (NPY) Y1 receptor antagonist PD160170 in promoting osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and accelerating healing of femoral defect in rats.
METHODSThe third generation of rat BMSCs were treated with PBS (control) or 10, 10, or 10 mol/L NPY Y1 receptor antagonist PD160170. After 7 and 14 days of treatment, the cells were examined for osteogenic differentiation with alkaline phosphatase (ALP) and alizarin red staining. At 7 and 21 days of treatment, the mRNA and protein expressions of collagen type I (COLI), osteocalcin (OCN) and Runt-related transcription factor 2 (Runx2) in the cells were detected using q-PCR and Westem Blotting. In a male SD rat model (body weight 300∓20 g) of bilateral femoral condyle defects (2.5 mm in diameter), the effect of daily local injection of 0.2 mL PD160170 (10 and 10 mol/L, for 28 consecutive days) in promoting bone defect repair was evaluated with micro-CT scans.
RESULTSALP and alizarin red staining showed that the BMSCs treated with PD160170, at the optimal concentration of 10 mol/L, contained more intracellular cytoplasmic brown particles and mineralized nodules in extracellular matrix than PBS-treated cells. PD160170 (10 mol/L) significantly up-regulated the mRNA and protein expressions of COLI at day 7 and those of OCN and Runx2 at day 21 (P<0.05). In the rat models of femoral bone defect, the volume/tissue volume ratio, bone mineral density and the number of bone trabeculae were significantly greater in 10 mol/L PD160170 group than in the control group (P<0.05), but the bone trabecular thickness (P=0.07) and bone volume (P=0.35) were similar between the two groups.
CONCLUSIONNPY Y1 receptor antagonist PD160170 can promote osteogenic differentiation of BMSCs and healing of femoral defects in rats, suggesting the potential of therapeutic strategies targeting NPY Y1 receptor signaling in the prevention and treatment of bone fracture and osteoporosis.

OBJECTIVETo diagnose and classify the congenital craniofacial cleft with a uniform scale is helpful to evaluate the abnormality and select the repairing methods.
METHODSWe analyzed 81 cases of congenital craniofacial cleft basically using Tessier craniofacial cleft classification. Furthermore, according to the position of soft tissue or bone, the character and degree of clefts or dysplasia and the results of CT scanning, we subdivided the congenital deformities based on S (skin), T (tissue), and O (OS). Arabic numerals were used to express the degree of the abnormality.
RESULTSOf all the cases analyzed with the STO classification, No. III and IV clefts are often seen in the infraorbital region (24.70%). No. IX and X clefts are mostly seen in the supraorbital region (38.27%). The relationship between the cleft types and involved tissue has not been found.
CONCLUSIONSThe STO classification reinforces Tessier classification. It offers the basis for craniofacial cleft repair.
