Objective To evaluate the value of MSCT three-dimensional reconstruction postprocessing technique for operation of Scoliosis Orthomorphia. Methods 18 cases of scoliosis were performed with MSCT to be reconstructed by MPR, VRT. The three-dimensional reconstruction images displayed traverse, coronal and sagittal plane and measures data. Results By measuring data of 18 cases by means of the methods above, all parameters were accurate. Conclusion The three-dimensional reconstruction of MSCT makes up the disadvantages of X-ray. Any retrospective reconstruction can be done to the collected data. So patients can avoid being projected repeatedly and radiation can be reduced. Various parameters of the vertebrae concerning spine, spinal canal and the pedicle plane can be offered, providing reliable reference for pre-operations.

Objective To measure the volume of liver, the volume of mass of liver and the ratio of mass/righe lobe with the Volume Evaluation of MSCT, as a reference of liver function after resection of liver mass. Methods All cases were scanned and reconstructed with MSCT,and the volume of right liver, the volume of mass of right liver and its ratio were obtained with Volume Evaluation of MSCT. Results The method of measuring volume of liver with Volume Evaluation is simple and accurate. Conclusion It can be a important reference before and after resection of liver mass.

ObjectiveTo investigate the expression and relationship between phosphatase and tensin homology deleted on chromosome ten(PTEN) and vascular endothelial growth factor(VEGF) in bladder transitional cell carcinoma(BTCC) and their clinical significance.MethodsExpression of PTEN and VEGF were detected in 60 specimens by immunohistochemistry test(SP method).ResultsThe positive rate of PTEN was 47%(28/60) in BTCC;VEGF was 68%(41/60).With the pathological grade and the clinical stage of tumors being higher,the lower expression level of PTEN showed(P<0.05);while the expression of VEGF increased with no statistical significance(P>0.05),but having a significant difference between specimens with lymph nodes metastasis and without lymph nodes metastasis(P<0.05).The expression of PTEN was negatively correlated with that of VEGF(r=-0.439,P<0.01).ConclusionThe expression of PTEN and VEGF in BTCC plays an important role during the progress of carcinoma and is helpful to evaluate the prognosis of patients.

GRP78/Bip,which was first identified by scientists in 1977,is a major endoplasmic reticulum (ER)chaperone that has a variety of function.In tumor tissue,GRP78 is high expression and ectopic expression;participate in the development of tumor,ER-stress state and ectopic distribution on the cell surface,in the form of receptors involved in signal transduction. Therefore,GRP78 as an tumor therapeutic targets,biomarkers of tumor and prognosis of tumor biological markers,plays an important role in the tumor research.In recent years,domestic and foreign scholars have found that in the non-cancer disease (viral infectious disease cardiovascular disease diabetes neurodegenerative disease etc),GRP78 is high expression,indicate its application prospect.This article makes a brief overview on the molecular biological characteristics of GRP78,role in tumor pathogenesis and therapeutic significance and application prospect in non-tumor disease.

Drug combination is extensive in the clinical real world,which is an important part and the inherent requirements of the post-marketing evaluation of traditional Chinese medicine (TCM). The key issues and technology include multi-domain and multi-disciplinary such as the rationality, efficacy and safety evaluation of combination drug starting from clinical real world, study on component in vivo and mechanism of combination drug, the risk/benefit assessment and cost-benefit evaluation of combination drug and so on. The topic has been studied as clinical demonstration on combination therapy of variety of diseases such as coronary heart disease, stroke, insomnia, depression, hepatitis, herpes zoster, psoriasis and ectopic pregnancy. Meanwhile, multi-disciplinary dynamic innovation alliance of clinical drug combination has been presented, which can promote the academic development and improving service ability and level of TCM.

Objective:To compare the properties of three kinds of denture base materials treated and untreated by hydraulic pressure cooker. Methods: The impact strength, flexural strength, flexural elastic modulus and color difference roughness of three denture base materials, Kunshan Rijin(KR),GC UNIFAST Trad(GC), Shanghai Zhangjiang(SZ), were measured in vitro. All results were statistically analyzed with SPSS software to have ANOVA and Tamhane's T2 tests, α=0.05. Results: Comparison of the same materials between the treated materials and the untreated materials by hydraulic pressure cooker: there were significant statistical differences of impact strength for all the materials. There were significant statistical differences of color difference for KR and SZ. Comparison of the three materials: impact strength, GC>SZ>KR;flexural strength, KR>SZ>GC;flexural elastic modulus, KR>SZ>GC;roughness, GC>KR>SZ. Conclusion: The properties of denture base materials treated by hydraulic pressure cooker are good.

AIM: To observe the inhibitory effect of interferon-α ( IFN-α) on the growth invasiveness and metastasis of human gastric carcinoma cell line BGC-823, and mechanism of its action. METHODS: We detected the influence of IFN-α on the proliferative ability of BGC-823 in cell culture system, the cell vitality with the MTT colorimetric assay, and the cell cycle with flow cytometer (FCM). The regulatory functions of IFN-α to the expression of E-cadherin and matrix metalloproteinase-2 ( MMP-2) in tumor cells were estimated by immunohistochemical analysis ( S-P). The ultrastructural changes of the junction among the tumor cells were observed under electron microscope. RESULTS : IFN-α can significantly inhibit the growth of human gastric carcinoma cell line BGC-823 in a dose-dependent manner. When the concentration of IFN-α was ≥106 U/L, the cell proliferation can be effectively suppressed,the suppression rate was ≥ 12. 2%, and the blockage appeared at the phase of G1-S of the cell cycle. Under the induction of IFN-α, the expression level of the cell E-cadherin increased while the MMP-2 decreased. The changes on ultrastructure of the cells showed the increased adhesive junctions and the relative compact structure. CONCLUSION: IFN-α can suppress the growth of human gastric carcinoma cell line BGC-823 through its influence on cell cycle. IFN-α can regulate the expression of E-cadherin and MMP-2, make the cell junction closely, so that it has the potential on restricting the invasion and metastasis of gastric carcinoma cells.
