ObjectiveTo discuss the feasibility of the method that can be used to induce the model of type 2 diabetic mellitus rat and explore the characteristic of the nephropathy.The rats were fed with the high sucrose,high fat and high energy feed for a long time and then it was injected with the low dose STZ.Methods30 SD rats were selected and then it was randomly divided them into 2 groups,the control group (10 rats) and the model group (20 rats).The model group was fed with the high calorie feed forl0 weeks to induce insulin resistance and then the rats were induced to type 2 diabetes mellitus by injection of streptozocin (30 mg/kg).The rats of the model group were continually fed with the high calorie feed for 2 months.Before the end of this study,the 24-hours microalbuminuria,serum creatinine and blood urea nitrogen were detected and the periodic acid Schiff staining on the kidney were also measured.ResultsAfter the rats of the model group were established,the levels of the bodyweight,the cholesterol,the triglyceride and the insulin were [ (468.7 ± 8.8 ) g,( 1.92 ± 0.27 ) mmol/L,( 1.32 ± 0.34) mmol/L,(38.81 ± 5.39 ) mU/L ] respectively,all of them were higher than the levels in the normal group,which were [ (436.9 ± 7.4) g,(1.16 ±0.17)mmol/L,(0.8 ±0.18)mmo1/L,(21.43 ±4.19)mU/L],respectively( t =9.755,8.077,4.437,8.902,P ＜ 0.01 ).After injection of STZ for 2 weeks,the levels of the blood glucose,the insulin and the insulin resistance of the diabetes mellitus rats were [ ( 19.31 ± 1.55 ) mmol/L,( 31.31 ± 8.60) mU/L,(26.55 ± 6.33) ] respectively,it was higher than levels inf the normal group,which was[ (5.45 ±0.69) mmol/L,( 19.97 ± 3.26) mU/L,(4.82 ± 0.84) ] ( t =26.383,3.951,10.719,P ＜ 0.01 ).Before the end of this study,the levels of the blood glucose,insulin resistance,24-hours microalbuminuria,serum creatinine,blood urea nitrogen of the diabetes mellitus rats were [ ( 19.27 ± 1.97 ) mmol/L,( 16.70 ±7.51 ),(72.49 ± 8.53 ) mg/24 h,( 74.76 ± 8.38 ) μmol/L,( 19.09 ± 4.21 ) mmol/L],it was higher than the levels in the normal group,which were [ (5.62 ±0.65) mmol/L,(5.45 ± 1、33),( 15.26 ±2.20) mg/24 h,(40.81 ± 1.97) μmol/L,(9.87 ±2.13) mmol/L,t =20.961,4.657,20.623,12.495,6.352,P ＜0.01 ].And the pathological changes of the diabetes mellitus rats kidney tissues were the most serious through themethod of periodic acid-Schiff's staining (PAS).ConclusionsThe model of type 2 diabetic mellitus rat was constructed through the way of feeding the SD rats with high sucrose,high fat and high energy feed for a long time and low dose STZ.The diabetic mellitus rats had the symptom of drinking more,eating more and diuresis,and the character of this model had high levels of albuminuria,serum creatinine,blood urea nitrogen.The incrassated glomerular mesangium,the crescent-shaped focus and the glomerulosclerosis were also observed through the PAS.

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.

Measurement of cervical lordosis is the basic method for evaluating cervical function, and important reference for determine treatment decision. However, how to choose appropriate measurement in accordance with different situation, as well as the relationship among these methods is not clear. An increasing number of studies suggested that different measurements could directly affect the judgment of cervical lordosis. Therefore, comparative study of cervical vertebrae plays an important role in clinical treatment for cervical spondylosis under different cervical curvature conditions.

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.

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.

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.
