BACKGROUND:Bisphosphonates that can increase bone density and inhibit bone resorption have been clinical y confirmed, but the structure of the bone matrix has been less studied.
OBJECTIVE:To observe the effects of alendronate on bone structure and bone matrix metabolism, and then to investigate the control ing mechanism by which alendronate improves bone mass and increase bone intensity.
METHODS:An ovariectomized rat model was prepared and intervened with alendronate as treatment group. Model and sham-surgery groups were set as controls. Alendronate effects on bone mineral density, bone metabolism, bone biomechanics, and bone structure were observed in bone loss rats using bone imaging, bone tissue pathology and biomechanical test and enzyme-linked immunosorbent assay.
RESULTS AND CONCLUSION:Alendronate intervention could fight against bone loss as compared with model group at weeks 4, 8, and 12 after treatment (P<0.05). Compared with the model group, the expression of urinary deoxypyridinoline and serum carboxyterminal propeptide of type Ⅰ procol agen was decreased significantly after alendronate intervention (P<0.05);the maximal load, maximal pressure and modelus on the lumbar vertebrae and femur were increased as wel as ratio of urinary pyridinoline/deoxypyridinoline of type Ⅰ procol agen (P<0.05). These findings suggest that alendronate intervention can inhibit bone loss in rats induced by estrogen deficiency, increase biomechanical properties, improve bone matrix structure, and meanwhile, recover the Ⅰ col agen crosslinking component due to ovariectomy.

Objective To investigate the role of cyclooxygenases (COXs) in the up-regulation of the expression of P2X3 receptors in the dorsal root ganglion (DRG) in rats with neuropsthic pain. Methods Twenty-four male SD rats, weighing 250-280 g, were randomly divided into 4 groups ( n = 6 each): sham operation group (group S), chronic constrictive injury (CCI) group, COX-1 inhibitor ibuprofen group (group Ⅰ), and COX-2 inhibitor celecoxib group (group C). Neuropathic pain was induced by CCI. The animals were anesthetized with intraperitoneal 10% chloral hydrate 300-500 mg/kg. CCI was produced by placing 4 ligatures on the left sciatic nerve at 1 mm intervals. In group S, the left sciatic nerve was only exposed but not ligated. In groups Ⅰ and C, ibuprofen 40 mg·kg-1 ·d-1 and celecoxib 30 mg·kg-1 ·d-1 were given through a gastric tube into the stomach at day 3-14 after operation respectively. Paw withdrawal latency (PWL) and paw withdrawal threshold (PWT) were measured before operation (baseline), and at 3, 5, 7, 10 and 14 days after operation. Then the rats were sacrificed and their L()-6 DRGs were removed to detect the expression of P2X3 mRNA and protein. Results Compared with group S, PWL was significantly shortened, PWT decreased, and P2X3 mRNA and protein expression up-regulated in group CCI ( P ＜ 0.05＝. Compared with group CCI, PWL was significantly prolonged, PWT increased, and P2X3 mRNA and protein expression down-regulated in groups Ⅰ and C (P ＜0.05＝. Compared with group Ⅰ, PWL was significantly prolonged, PWT increased, and P2X3 mRNA and protein expression up-regulated in group C ( P ＜0.05＝. Conclusion COXs are involved in the up-regulation of the expression of P2X3 receptors in the DRG in rats with neuropathic pain, and the effect of COX-1 is stronger than that of COX-2.

Objective To investigate the existence of pulmonary vascular remodeling after left pneumonectomy in rats and the role of hypoxia inducible factor-lα( HIF-1α) and vascular endothelial growth factor ( VEGF) in pulmonary vascular remodeling.Methods Twenty-four healthy male Sprague-Dawley rats were randomly divided into experimental and control groups, 12 in each group.The rat models of pulmonary vascular remodeling were created by open-chest left pneumonectomy.After 12 weeks of feeding, the mean pulmonary artery pressure ( mPAP) and partial pressure of arterial oxygen ( PaO2 ) of each rat were measured.The ultrastructure of small arteries in the lung specimens were examined by e-lectron microscopy.Muscularized degree of three kinds of small pulmonary vessels ( muscularized artery MA, partially mus-cularized artery PMA, and non-muscularized artery NMA) were observed by light microscopy, and the percentage of each kind of pulmonary arteries ( MA%, PMA%, NMA%) were calculated.Arterial external diameter, media thickness of ves-sel ( MTV) , total vascular area, media area of vessel ( MAV) , MTV%and MAV%were calculated as indicators of pul-monary vascular remodeling.The expressions of HIF-1αand VEGF in artery were detected by immunohistochemistry.Re-sults The values of mPAP, MA%, PMA%, MTV, MAV, MTV% and MAV% in the experimental group were signifi-cantly higher than those in the control group (P<0.01), but the value of PaO2 and NMA%were significantly lower than those in the control group (P<0.01).The IOD value of HIF-1αand VEGF expressed in the pulmonary arterial wall of the experimental group were 26.47 ±4.16 and 42.04 ±3.79, respectively, significantly higher than those in the control group (6.12 ±2.14 and 11.53 ±2.29, P<0.01).Linear correlation analysis showed that the expression of HIF-1αand VEGF was positively correlated with MTV% and MAV%, negatively correlated with PaO2 , and the HIF-1αexpression was posi-tively correlated with VEGF expression.Conclusions A rat model of pulmonary vascular remodeling can be successfully established by left pneumonectomy.Hypoxia is a key factor in the development of pulmonary vascular remodeling, HIF-1αand VEGF may play an important role in its pathogenesis.

BACKGROUND:At present, the common filing materials used to correct secondary unilateral cleft lip nasal deformity include conchae cartilage, costal cartilage, Medpor implants, expanded polytetrafluoroethylene (ePTFE), alogenic acelular dermal matrix. OBJECTIVE:To analyze the therapeutic effects of comprehensive procedures with alogenic acelular dermal matrix or ePTFE for secondary unilateral cleft lip nasal deformity. METHODS: Thirty-six patients with secondary unilateral cleft lip nasal deformity were enroled, including 19 males and 17 females, aged 15-32 years. Alogenic acelular dermal matrix (n=22) or ePTFE (n=14) was used to correct nasal base colapse deformities. Anthropometry method was employed to make measurements. Fixed-point measurement was performed based on patient's pictures before and after correction. Long-term effects of these two kinds of filing materials were analyzed and assessed objectively and quantitatively. RESULTS AND CONCLUSION: After the folow-up of 6 months, al the patients were satisfied with their results, and no infection and no exposure occurred. The treatment effect of the alogenic acelular dermal matrix group was excelent in 16 cases and good in 6 cases; there were 10 cases of excelent and 4 cases of good in the ePTFE group. The objective indicators in the two groups were al improved at 6 months after correction (P < 0.05), but there was no difference between the two groups (P > 0.05). These findings indicate that alogenic acelular dermal matrix or ePTFE is useful to correct secondary unilateral cleft lip nasal deformity.
