Objective: To study the effect of the sharp marginal ridge of the abutment on the casting of the fit metal full crown in dental preparation.Methods: We established the models of the designed crown-based-teeth(American Dental Association style,No2 trail) with a sharp or smooth marginal ridge,and cast a metal crown for each model.We injected silicone into the crown and immediately fixed it onto each model.Then we took out the solidified silicone and measured its thickness between the crown and the occlusal face of each model.The thinner the thickness,the better the fitness.Results: The average silicone thickness was 250 ?m in the smooth marginal ridge group and 1 660 ?m in the sharp marginal ridge group,with significant difference in between(P

AIM:To discuss Daidzein intravitreal injection whether has protective and recovery effects on acute nerve damages.
METHODS:After the crush models of acute optic nerve were set up, 72 males SD rats were divided into 4 groups randomly as common group without surgery, FBS negative control group, Daidzein treatment group ( 10μmol/L, 100μmol/L, 1000μmol/L ) and positive control group using rats nerve growth factor ( mNGF, 100ng/mL ). Three days after interference, all experimental animals were executed. HE staining was used to evaluate morphologic change of the retina, immunohisochemical staining and western-blot tests for identifying and quantifying the distinct expression of Caspase-3 and GAP-43 among the groups.
RESULTS: Compared with the normal group and negative control group, retinal morphology of different concentrations of each Daidzein treatment group and positive control group was more complete, the expression of Caspase-3 protein was relatively lower, the expression of GAP-43 protein was relatively higher, the differences have statistically significance (P<0. 05).CONCLUSION: Daizein injection in the vitreous cavity has the capacity of protection and restoration in rat's acute nerve damages.

Objective To observe the clinical effect of neonatal respiratory failure therapy with mechanical ventilation. Methods Forty - eight cases of neonatal respiratory failure were applied endotracheal intubation through mouth. At first, ventilation was given via the intermittent positive - pressure ventilation + peak end - expiratory pressure( IPPV + PEEP) way. Later, the breath parameters were regulated and transited to the intermittent mandatory ventilation( IMV) way according to original illness. When frac - tional concentration of in-spired gas(FiO2)

Objective To explore the risk factors for early interhepatic recurrence and metastasis of hepatocellular carcinoma (HCC)on CT imaging before treatment.Methods 1 1 5 patients suffered from HCC from July 2003 to January 2009 were retrospec-tively enrolled for reviewing their clinical characteristics and CT signs.The status of metastasis and/or recurrence was followed reg-ularly.Signs on pre-treatment enhanced CT images were measured and analyzed.Analysis of variance and independent sampler t test were applied for Univariate survival analysis.Then multivariate analysis was carried out by the Logistic regression,Lon rank meth-od,and p-value < 0.05 was defined to be statistically significant.Results The early interhepatic recurrence and metastasis rate of the study group was 58.26%.With univariate analysis,tumor size,location,extent,capsule,satellite nodule,vascular invasion, AVM and necrosis were the risk factors for early recurrence and metastasis of HCC on pre-treatment enhanced CT imaging (P<0.05).Multi-variable Logistic regression analysis showed that tumor size,satellite nodule,vascular invasion capsule and were independently sig-nificant CT signs for early interhepatic recurrence and metastasis of HCC (P =0.031,0.005、0.037、0.048).Conclusion Pre-treat-ment enhanced CT imaging with HCC was closely related to early interhepatic recurrence and metastasis of the tumor.A tumor of larger size,with satellite nodules,without complete capsule and vascular invasion on CT may predict a tendency to early interhepatic recurrence and metastasis of HCC.

AIM: To observe the alteration of urotensin II (UII) receptors and contractile response to UII in rat aorta after balloon angioplasty injury. METHODS: The plasma membrane isolated from balloon injured aorta was used to study the binding of [ 125 I]-UII to the membrane and the contractile potency of UII on rat aorta was assayed. RESULTS: In contrast to the normal aorta, the contractile potency to UII enhanced in balloon injury artery and the calculated maximal number of specific binding sites (Bmax) was increased about 44% and 36% respectively in rat artery after balloon injury 3 and 21 days ( P
