OBJECTIVETo study the color reappearance effect of metal-ceram restoration and foundry-ceram restoration using Crystaleye spectrophotometer.

METHODS58 metal-ceram restorations and 58 foundry-ceram restorations according to the result of the Crystaleye spectrophotometer were made respectively. The deltaE between restorations and natural teeth as referenced were analyzed. And satisfaction of dentists and patients were evaluated.

RESULTSThe deltaE between metal-ceram restorations and natural teeth was 7.13 +/- 0.74. The deltaE between foundry-ceram restorations and teeth was 1.47 +/- 0.84. There were statistical differences between the deltaE (P < 0.01). The satisnatural faction of dentists and patients to the foundry-ceram restorations were higher than to the metal-ceram restorations (P < 0.05).

CONCLUSIONCrystaleye spectrophotometer can provide accurate reference for foundry-ceram restoration, but for metal-ceram restoration it is not accurate.

OBJECTIVETo investigate the effect of Rongshi granule on osteopontin(OPN) expression.

METHODThe urlisthiasis rats were induced by ethylene glycol (EG) and ammonium chloride, the control group rats were non-treated, and the Rongshi granule groups (low-dose group, middle-dose group and high-dose group) were administered Rongshi granule in addition to EG and ammonium chloride in 21 days. Pooled 24 h urine samples from each group were collected weekly with the use of metabolic cages, the concentration of uric calcium and oxalic acid were respectively measured by EDTA and photoelectric colorimetric method. Eight animals from each group were killed at 0, 7, 14, and 21 days, kidneys were histologic examinaed and immunohistochemical staining.

RESULTThe expression of kidney osteopontin in model group was obviously higher than that of control group (P <0.01), and was up to the highest at 21 days with 1.4 times (0.281 3/0.201 8) of the control group. The expression of kidney osteopontin in all of the Rongshi granule groups were lower than those of model group (P < 0.05), with an obvious dose-dependent manner. The degree of the kidney calcium oxalate crystal of the rats in all the Rongshi granule groups was much lower than that of model group, and the uric calcium and oxalic acid were much lower than those of model group (P < 0.01).

CONCLUSIONThe Rongshi granule could inhibit the expression of osteopontin in rat urolithiasis model.

Objective To evaluate the effect of bone marrow mesenchymal stem cell (BMSC) on the expression of interleukin (IL)-10 and tumor necrosis factor (TNF)-α in mice with ischemia-reperfusion acute kidney injury (IR-AKI). Methods All mice were randomly divided into the sham operation group (control group), ischemia-reperfusion injury group (IRI group) and BMSC treatment group (BMSC group), with 6 mice in each group, respectively. The renal function and pathological changes of mice were detected. The cell apoptosis of renal tissues of mice was determined. The expression levels of serum IL-10 and TNF-α of mice were quantitatively measured. The mouse BMSC was randomly divided into the control and hypoxia-reoxygenation groups (IRI group), and the expression levels of IL-10 and TNF-α in cell supernatant were determined. Results The renal structure of mice was normal in the control group, severe damage was observed in the IRI group, and mild damage occurred in the BMSC group. Compared with the control group, the renal tissue injury scores were significantly higher in the IRI and BMSC groups (both P < 0.05). Compared with the IRI group, the renal tissue injury score was significantly lower in the BMSC group (P < 0.05). Compared with the control group, the levels of serum creatinine (Scr) and blood urea nitrogen (BUN) were remarkably up-regulated in the IRI group, and the level of BUN was significantly up-regulated in the BMSC group (all P < 0.05). Compared with the IRI group, the levels of Scr and BUN were significantly down-regulated in the BMSC group (both P < 0.05). In the IRI group, the quantity of apoptotic cells in the renal tissues was considerably higher than those in the BMSC and control groups, and the quantity of apoptotic cells in the BMSC group was significantly higher than that in the control group (all P < 0.05). Compared with the control group, the levels of serum IL-10 and TNF-α were significantly up-regulated in the IRI group, whereas the level of serum TNF-α was significantly down-regulated and the level of serum IL-10 was significantly up-regulated in the BMSC group (all P < 0.05). Compared with the IRI group, the levels of serum IL-10 and TNF-α were significantly down-regulated in the BMSC group (both P < 0.05). The levels of IL-10 and TNF-α in the cell supernatant did not significantly differ between the IRI and control groups (P=0.080、0.627). Conclusions BMSC infusion may reduce the incidence of renal IRI and inflammation, probably via the mechanism of down-regulating TNF-α expression rather than up-regulating IL-10 expression.
