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.

BACKGROUND: Type Ⅰ collagen is a specific collagen secreted by in vitro cultured osteoblast, and the formed network is the basis of bone mineralization, which also reflects the ability of osteoblast bone formation. Studies have shown astragalus root increased osteoblast proliferation. However, the effect of astragalus root on improving type Ⅰ collagen expression of osteoblast remains poorly understood.OBJECTIVE: To evaluate the effect of astragalus root injection on the abilities of rat cranium-derived osteoblast proliferation and type Ⅰ collagen expression.METHODS: Rat osteoblast was cultured in vitro and divided into control group (MEM culture solution containing calf serum) and astragalus root groups (different concentrations). The effect on osteoblast proliferation was evaluated on days 1, 3, 5, 7, and 9 by MTT method. Moreover, the expression of type Ⅰ collagen protein was observed after 6 hours of treatment with astragalus root injection using in cell western-blot method. In addition, the gene expression of COLLal was investigated by real-time PCR method.RESULTS AND CONCLUSION: From days 3 to 9, the different concentrations of astragalus root injection improved osteoblast proliferation, respectively compared with control group (P ＜ 0.05), and this ascending trend peaked on day 7. Different concentretions of astragalus root injection improved COLLol mRNA expression, especially 15% astragalus root injection was the most effective. The type Ⅰ collagen protein expression of 15% and 10% astragalus root injection were significantly greater compared with the control group (P ＜ 0.05). Astragalus root injection improved in vitro cultured osteoblast proliferation and type Ⅰ collagen secretion in a certain dose-effect manner.

Objective To study the influence of clinicopathologic characteristics and surgical treatment of gastric cancer on patients' survival rate.Methods From Apr.1994 to Aug.2005, the data of 759 gastric cancer patients concerning surgical treatment, pathological diagnosis and outcome were collected. Retrospective analysis of the results was made, 3-year and 5-year survival rates were calculated by Kaplan-Meier curve method, univariate analysis was done through Log-rank and multiple factors comparison through Cox regression analysis, and follow-up duration was 4-131 months.Results Single factor analysis indicated that age,tumor location,diameter of tumor, Borrmann type, type of histology, TNM stage, depth of infiltration, lymph node metastasis, liver metastasis, peritoneal dissemination, blood of transfusion during operation, extent of the radical cure of the tumor and excision techniques were significantly influential factors for the prognosis of patients. Cox regression analysis showed that tumor location, diameter of tumor,depth of infiltration, lymph node metastasis,liver metastasis, TNM stage, peritoneal dissemination, blood transfusion during operation, extend of the radical cure of the tumor and excision techniques were independent factors influencing the postoperative survival rate.Conclusion Independent factors influencing the postoperative survival rate include tumor location, diameter of tumor, lymph node metastasis, infiltration depth of the tumor, pathological classification, liver metastasis, peritoneal dissemination, and TNM stage, extent of the radical cure of the tumor, lymphanodectomy techniques and blood transfusion during operation are also important factors.

0.05 by ? 2 test (? 2=0.487). CT angiography of SSD, MIP, and CT virtual vascular endoscopy could show the location, extent and degree of occlusion or stenosis of internal carotid arteries clearly. CT angiography could also detect calcific plaque in 21 internal carotid arteries and soft plaque in 15 internal carotid arteries. Conclusion Two slices CT perfusion imaging could be made with regular helical CT scanner. CTA could also evaluate the status of plaque. The combination of CT perfusion imaging and CTA are useful not only in observing the morphology of internal carotid arteries, but also in observing the hemodynamic information of the brain, which are important for further general individual analysis.

Background The primary management for nasolacrimal duct obstruction is the combination of lacrimal duct probing with lacrimal duct stent implantation.However,conventional implant is undegradable.New degradable lacrimal duct prosthesis based on biopolymer materials is a research hotspot.Objective This study described herein a preparation method of novel degradable lacrimal duct prosthesis and its application.Methods A new degradable lacrimal tube stent was prepared with compound of poly L lactic acid (PLLA) and polycaprolactone (PCL) (6:4) and 15％ polyethylene glycol (PEG).Thirty-two Japanese rabbits aged 3-4 months were randomized into postoperative 1-week group,postoperative 4-week group,postoperative 8-week group and postoperative 16-week group.The degradable lacrimal tube stents were inserted into the lacrimal ducts of the left eyes of the rabbits.The prosthesis was removed in corresponding time points according to grouping,and the integrity and weight of the prosthesis were evaluated.The mucosal findings of the operative eyes were examined under the endoscope,and the histopathological and inflammatory reaction was observed by hematoxylin & eosin stain.The ultrastructure of the lacrimal mucosal surface was examined under the scanning electron microscope.The use and care of the rabbits complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The new degradable PLLA:PCL+15％ PEG lacrimal duct stents were smooth,flexible and hydrophilic tubes.The removed tubes were intact in the postoperative 1-week group,however,the rupture of the tubes appeared in the postoperative 4-week group,while discrete pieces of the tubes were seen in the postoperative 16-week group.The weight-loss rates of the tubes were (13.44±6.59)％,(23.96±6.33)％,(55.08-± 6.55) ％ and (78.00±8.74) ％ in the postoperative 1-week group,postoperative 4-week group,postoperative 8-week group and postoperative 16-week group,respectively,and the weight-loss rate of the tubes was significantly higher in the postoperative 16-week group than those in the postoperative 8-week group (q =4.27,P＜0.05).No significant difference was found in the weight-loss rate of the tubes between postoperative 1-week group and postoperative 4-week group (q =1.71,P＞0.05).The edema,hyperemia and mild proliferation of the lacrimal mucosal were exhibited in the eyes of the postoperative 4-and 8-week groups,and the mucosal findings were almost normal in the eyes of the postoperative 16-week group under the endoscope.Histopathological examination showed a large number of inflammatory cells in the postoperative 1-,4-and 8-week groups.However,few inflammatory cells were seen in the postoperative 16-week group.Mucosal folds,microvillus decrease and disorder were displayed in the lacrimal duct of the postoperative 8-week group,and no evident abnormality was seen in the lacrimal duct mucosal surface.No postoperative complication occurred in all the rabbits.Conclusions PLLA:PCL+15％ PEG lacrimal duct stent has an appropriate degradation speed and good biocompatibility after implant in rabbits,and its decay period of mechanical strength could match lacrimal duct healing period.
