OBJECTIVETo evaluate the effect of microwave sintering on the translucency of zirconia and to compare these effect with those of conventional sintering. The relationship between the microstructure of specimens and translucency was investigated.
METHODSA total of 10 disc-shaped specimens were fabricated from 2 commercial brands of zirconia, namely, Zenostar and Lava. Each group included 5 discs. Conventional sintering was performed according to the manufacturers' specifications. The maximum temperature for Zenostar was 1,490 °C, whereas that for Lava was 1,500 °C. The dwelling time was 2 h. The sintering temperature for microwave sintering was 1,420 °C, heating rate was 15 °C · min⁻¹, and dwelling time was 30 min. After sintering, the translucency parameter (TP) of the specimens were measured with ShadeEye NCC. The sintered density of the specimens was determined by Archimedes' method. The grain size and microstructure of the specimens were investigated by scanning electron microscopy.
RESULTSDensity and translucency slightly increased by microwave sintering, but no significant difference was found between microwave and conventional sintering (P > 0.05). Small and uniform microstructure were obtained from microwave sintering. The mean TP of Lava was significantly higher than that of Zenostar (P < 0.001).
CONCLUSIONThe translucency of zirconia sintered by microwave sintering is similar to that of the zirconia sintered by conventional sintering.

Background:It was demonstrated that vitamin D has extensive biological effects,and evidence exists on association between vitamin D and a variety of immune mediated diseases such as inflammatory bowel disease. Aims:To investigate the relationship between serum level of 25-hydroxyvitamin D(25OHD)and disease activity and quality of life in patients with ulcerative colitis( UC). Methods:Serum level of 25OHD was detected by electrochemiluminescence in 50 outpatients/inpatients with UC from Oct. 2015 to Mar. 2016 at the Anhui Provincial Hospital;35 healthy subjects were served as normal controls. CRP,ESR and PLT were determined by routine laboratory tests in UC patients. Disease activity of UC was assessed by improved Mayo score,and Chinese version IBD questionnaire( IBDQ)was employed to assess quality of life. Results:Vitamin D deficiency defined as serum 25OHD ﹤20 ng/mL was detected in 68. 0% of the UC patients. The mean value of serum 25OHD was significantly lower in UC group than in normal control group[(16. 73 ± 8. 83)ng/mL vs.(19. 84 ± 4. 56)ng/mL,P﹤0. 05]. When patients were stratified with disease activity,serum level of 25OHD decreased in the order of remission,mild,moderate and severe active stage(P ﹤0. 05). In UC patients with vitamin D deficiency,the value of CRP,ESR and PLT were significantly increased(P all ﹤0. 05)and the overall score of IBDQ and scores of four dimensions of IBDQ referring to bowel symptom,systemic symptom,emotional function and social function were significantly decreased(P all ﹤0. 05). Spearman and Pearson correlation coefficients analyses showed that serum level of 25OHD was negatively correlated with Mayo score,CRP,ESR and PLT(P all ﹤0. 05),and positively correlated with scores of IBDQ,including overall score and four dimensional scores in UC group( P all ﹤0. 05 ). Conclusions:Vitamin D deficiency occurs frequently in patients with UC and might have a negative impact on disease activity and quality of life.

BACKGROUND:Most bone marrow mesenchymal stem cel s are infused intravenously and have very low efficiency of homing to the bone marrow. However, cel infusion via the femoral approach is little reported. OBJECTIVE:To explore the distribution of luciferase gene modified red fluorescent protein transgenic bone marrow mesenchymal stem cel s in vivo through different infusion routes. METHODS:Luciferase gene modified bone marrow mesenchymal stem cel s at different gradients (5×106, 1×106, 1×105, 1×104) were seeded or injected into the in vitro pore plate or free femurs to observe the fluorescence imaging and select the best concentration of cel s. Luciferase gene modified bone marrow mesenchymal stem cel s at the best cel concentration were injected into the mice via the femur and the tail vein, respectively. The distribution of fluorescence and cel number in the mice were explored by using bioluminescence, pathological examination, flow cytometry and quantitative PCR. RESULTS AND CONCLUSION:Ex vivo fluorescence intensity of luciferase gene modified bone marrow mesenchymal stem cel s was positively correlated with the cel concentration;fluorescent cel s in vivo appeared in the femur first and then quickly spread to the lungs in the femur group, while fluorescent cel s in the tail vein group spread to the lungs quickly after cel infusion. Fluorescent cel s could be seen in the spleen, liver and other organs 24 hours later in the two groups. The distribution and migration of cel s in mice could be observed successful y by bioluminescence;5 minutes after cel infusion, the lungs of mice in the two groups began to emit fluorescence that could spread to the liver, spleen and other tissues 24 hours later, and the fluorescence intensity reached its peak after 15 minutes. The distribution of bone marrow mesenchymal stem cel s in mice had no significant difference between the femur group and the tail vein group. To conclude, cel injection through the bone marrow cavity and tail vein fails to promote the homing of bone marrow mesenchymal stem cel s to the bone marrow.
