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

Objective The occurrence and progression of renal cell carcinoma ( RCC) is complicated process associated with DNA abnormal methylation , histone modification , and Wnt signaling pathway .This study aimed to investigate the expression of histone methylase SET8 in RCC, its relationship with the Wnt signaling pathway , its action mechanism in RCC , and its clinical significance . Methods We selected 50 cases of RCC treated by radical nephrectomy , detected the expression of SET 8 in the RCC and adjacent noncancerous kidney tissues by immunohistochemical EliVision two-step staining with β-catenin.We compared the expression levels of SET8 and β-catenin in the two types of tissue and analyzed their relationship with the patients′clinical information and the pathologic stage and grade of tumor as well as the correlation between the SET 8 andβ-catenin expressions . Results SET8 was mainly express in the cytoplasm of the RCC and noncancerous kidney tissues , partially in the cell membrane and nucleus , while theβ-catenin protein chiefly in the cell membrane of renal tubular epithelial cells in the normal kidney tissue .The expression levels of SET 8 and β-catenin in the RCC tissue were closely related to the TNM stage and tumor grade (P<0.05).The positive expression of SET8 in the RCC tissue (76%[38/50]) showed no significant difference from that in the ad-jacent noncancerous kidney tissue (66% [33/50]) (P>0.05), but that of β-catenin was remarkably higher in the former (68%[34/50]) than in the latter (4%[2/50]) (P<0.01).There was a positive correlation between the positive expression of SET 8 and the abnormal expression of β-catenin (r=0.219, P<0.05). Conclusion SET8-activated H4K20me-1 controls the activation and abnormal activities of the Wnt signaling pathway , affects the gene transcription and cell activity , and participates in the occurrence , progression, and distant metastasis of RCC .

Objective To study the impact of HIV and hepatitis C virus ( HCV ) infection on peripheral expression of antiviral protein A3G and plasma IFN-αlevels.Methods Untreated patients with chronic hepatitis C(HCV infection group, n=43), AIDS(HIV infection group, CD4 +T<200 cells/μL, n=45) and HIV/HCV co-infection (CD4 +T<200 cells/μL, n=45) were recruited in the study, and 23 healthy subjects were also enrolled as controls.A3G mRNA in peripheral blood mononuclear cells (PBMC) was measured by quantificational real-time PCR, and plasma IFN-αlevel was determined by enzyme linked immunosorbent assay (ELISA).Rank-sum test and Spearman rank correlation analysis were performed. Results A3G mRNA levels in HIV infected group, HIV/HCV co-infected group, HCV infected group and healthy control group were 4.89 (0.59), 4.85 (0.71), 3.89 (1.08) and 3.69 (0.81) lg copies/mL, respectively.A3G mRNA levels in HIV infected group and HIV/HCV co-infected group were much higher than those in healthy control group (Z=-6.306 and -6.280, P<0.01) and HCV infected group (Z=-7.358 and -7.275, P<0.01).Plasma IFN-αlevels in HIV infected group, HIV/HCV co-infected group, HCV infected group and healthy control group were 2.79 (1.25), 2.05 (1.29), 2.32 (1.84) and 2.16 (2.19) pg/mL, respectively.Plasma level of IFN-αin HIV infected group was higher than that in the HIV/HCV co-infected group (Z=-2.332, P<0.05), but no significant difference was observed among other groups (all P>0.05).There was no significant correlation between plasma IFN-αlevel and A3G mRNA expression (rs =0.04, P>0.05), and the levels of A3G mRNA and IFN-αshowed no correlation with HIV RNA and HCV RNA (all P>0.05).Conclusions A3G is highly expressed in PBMCs from HIV infected patients, and it may not be affected by the infection of HCV.A3G mRNA is not closely correlated with IFN-α, and it has not significant influence on HIV RNA and HCV RNA replication.

Objective To explore the relating factors for cognitive dysfunction in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods Totally 150 patients with acute exacerbation of COPD (AECOPD) and 150 gender and age-matched healthy subjects (controls) received the cognitive and depression function assessment.150 AECOPD cases were classified into two groups:COPD patients with or without cognitive dysfunction.Fasting blood uric acid (UA) was measured and compared between the two groups.Relating factors for cognition dysfunction were analyzed.Results The score of Montreal Cognitive Assessment (MoCA) was reduced in AECOPD patients as compared with controls [(19.01±3.58) vs.(26.58±1.42)scores,t=-3.48,P=0.032].The score of Hamilton depression (HAMD) scale was higher in AECOPD patients than in controls [(18.05 ± 4.50) vs.(9.98 ± 3.51) scores,t =4.63,P =0.028].The prevalence of cognitive impairment in the patients with AECOPD was 82 cases (54.7％).The serum UA level was lower in the AECOPD patients with cognitive impairment than in patients without cognitive impairment [(235±42) μmol/L (n=82) vs.(332±45) μmol/L (n=68),t=-6.65,P=0.003].In AECOPD patients,the cognitive function was correlated with education,length of hospital stay,serum UA level,COPD stages,disease duration and the depression level,but was not correlated with smoking and body mass index.Conclusions The cognitive impairment is highly prevalent in patients with AECOPD,which is associated with lower serum UA level,longer hospital stay and disease severity.
