2. Bio-oss combined with fibrin glue in reconstruction of canine mandibular defects
Academic Journal of Second Military Medical University 2010;28(6):620-623
Objective: To evaluate the osteogenic activities of Bio-oss after combining with fibrin glue in reconstruction of canine mandibular defects. Methods: The second and fourth premolar teeth and the second molar teeth were extracted bilaterally, in 9 hibrid canines, resulting in 6 bone defects (1 cm × 1 cm) in each canine. Bio-oss, Bio-oss+FG and FG were implanted into the bone defects of the second, fourth premolar teeth and the second molar teeth, respectively. Canines were executed in group of 3 after 4, 8, and 12 weeks to observe the healing of soft tissues. The bone density was assessed by X-ray, the property of Bio-oss were observed via gross specimen, and the morphology of the newly-formed bone was observed by tissue sections. The proportion of newly-formed bone was obtained by computer image analysis (SAS software, analysis of variance). Results: Stage I healing of soft tissues was achieved in all animals. The bone densities were not significantly different between Bio-oss+FG and Bio-oss groups. The bone in FG group had transparent area. We also found that the bone in Bio-oss+FG group was closely combined and there were sccatered Bio-oss dusts in the soft tissues of the Bio-oss group. The newly-formed bone in the FG group was only found in the border between the defects and FG. The proportion of newly-formed bone was less in the Bio-oss+FG group than in the Bio-oss group at 4, 8, and 12 weeks after extraction(P<0.05). Conclusion: Fibrin glue can well shape the Bio-oss and has satisfactory biocompatibility, but it reduces the new bone forming.

Objective:To analyze the DKK1 expression in breast cancer cell line MDA-MB-231 and examine its effect on the mi-gration and invasion of the cell line. Method:DKK1 expression in the breast cancer tissues was detected immunohistochemically, and DKK1 distribution in the breast cancer cells was observed using immunofluorescence. Western blot was used to investigate DKK1 ex-pression in breast cancer tissues and their matched normal breast tissues. A eukaryotic expression vector of DKK1 was constructed and transfected into MDA231 cell line. The migration and invasion ability of the cells were observed through scratch assay and Boyden chamber, respectively. Results: Immunohistochemical staining showed that DKK1 in the transfected lymph node or non-lymph node was highly expressed in the breast cancer tissues (P<0.05). The positive DKK1 expression in lymph node metastasis was less signifi-cant than those in non-lymph node transfected cells. Immunofluorescence localization results showed a remarkable bright red granular fluorescence in the cytoplasm of the MDA231 cell line. Western blot analysis showed that the DKK1 protein expression in carcinoma tissues were obviously higher than that in matched normal breast tissues. The migration and invasion ability of DKK1-overexpressed MDA231 cell was lower than those of MDA231 cell transfected with pCMV-Tag-2b empty vector. Conclusion:Negative correlation was found between DKK1 expression and the migration and invasion ability in breast cancer cells.

Objective To study the protective role against cisplatin-induced ototoxicity by using radix astra-gali in rats. Methods Forty rats were randomly divided into four groups. Group A received saline as controls. Group B received radix astragali. Group C received injection of cisplatin(4 mg/kg) as experiments for 6 days. Group D received both radix astragali (5 g/kg) and cisplatin (4 mg/kg). Distortion product acoustic emission (DPOAE) was applied to each rat before and 7 days after cisplatin injection. All the animals were sacrificed on the 7th day. Half of the cochleas were observed by frozen section and the apoptosis of hair cells was detected by TUNEL meth-od. Scanning electron microscopy was utilized to evaluate the cochlear morphology of the other rats. Results The DPOAE amplitudes of Group C decreased significantly compared to the group A and group B(P<0.01). The dam-age and apoptosis of hair cells were noted in the group C and group D, while the hair cells of group A and group B showed no sign of apoptosis or damage. Compare to experimental group , the DPOAE amplitudes of group D were higher, and the damage and apoptosis of hair cells were significantly lower(P<0.05). Conclusion This study sug-gests that radix astragali can effectively reduce cisp[atin ototoxicity.

Protein tyrosine kinase genes are the largest family of oncogenes. This is not surprising since protein tyrosine kinases are important components of signal transduction pathways that control cell shapes, proliferation, differentiation, and migration. This review will address the recent progress in understanding the function of Eph receptor and ephrin ligands in normal development and how disregulation of these functions could promote tumorigenesis.
