Chinese Journal of Experimental Ophthalmology 2011;29(10):907-912
Background Inflammation and adipogenesis are two parallel processes with increasing activity in severe thyroid-associated ophthalmopathy(TAO),and mevastatin was proved to have the inhibiting effect on the differentiation of adipose.Objective The aim of this work was to investigate the effects of mevastatin on the expression of cyclooxygenase-2(COX-2)and peroxisome proliferator activated receptor-γ(PPAR-γ)and differentiation of TAO-derived orbital preadipocytes,and explore its modulation effects on lipopolysaccharide(LPS)induced inflammation and the differentiation of TAO-derived orbital preadipocytes in vitro.Methods The retroorbital adipose tissue was obtained from 4 TAO patients during the surgery.The orbital fibroblasts were cultured from orbital adipose tissues using explant culture method.To study the suppressing effect of mevastatin on inflammatory response,cultured cells were divided into 5 groups.The 1000 μg/L LPS orbital fibroblasts were stimulated for 8 hours in group A,and 1000 μg/L LPS combined with 5 μmol/L,10 μmoL/L or 20 μmoL/L mevastatin were used respectively for the substitute in the group B,group C and group D.The orbital fibroblasts in group E were cultured routinely without any intervention as control.To observe the inhibiting effect of mevastatin on the differentiation of adipose,the group A were then subdivided into group A1-A6.After 1000 μg/L LPS was used to treat the cells for 8 hours,the ceils were induced to differentiate into adipocytes.All orbital preadipocytes from A1 to A6 were stimulated to differentiate into mature adipocytes with cocktail differentiation medium for a 10-day duration.During the procedure,group A2,A3 and A4 were interfered with 5,10 or 20 μmol/L mevastatin,and in the group A5 and A6,10 μmol/L mevastatin were added at the fourth day or eighth day.Intracellular fat accumulation in differentiated adipocytes was determined by oil red O staining.The absorption(A492 nm)was measured in the ceils by enzyme-linked immunosorbent assay(ELISA).Expression of COX-2 and PPAR-γ mRNA was detected by reverse transcription polymerase chain reaction(RT-PCR),and the expression of COX-2 and PPAR-γ protein was detected by Westernblot.The level of PGE2 in the supernatant was detected by ELISA.Results The expression of COX-2 protein and mRNA as well as the PGE2 levels in B,C,D group decreased markedly in comparison with those in A group(P<0.05).With the increase of mevastatin concentration,the expression of COX-2 protein and mRNA as well as the PGE2 levels in B,C,D groups decreased successively(F =228.380,101.745,1586.881,P<0.05).The expression of COX-2 protein and mRNA and PGE2 levels in E group were lower significantly than those in A,B and C groups(P<0.05),but no significant differences were found between E group and D group(P>0.05).The A492 value and the expressions of PPAR-γ protein and mRNA in differentiated cells showed the successively decrease in A1-A4 group with the elevation of mevastatin concentration(P<0.05),and the evidently decreased A492 value and the expressions of PPAR-γ protein and mRNA also were seen in A1 and A5 groups compared with A3 group(P < 0.05).Conclusions Mevastatin inhibits LPS-induced COX-2 expression,PPAR-γ expression,PGE2 secretion and differentiation of TAO-derived orbital fibroblasts in vitro in dose-dependent manner.Mevastatin plays these effect more prominently in early stage of adipocytes differentiation.

Objective To study the change rule of serum brain natriurectic peptide (BNP)and uric acid(UA)in the patients with heart failure and its clinical significance.Methods Serum BNP and UA levels in 84 patients with heart failure (observation group)and 30 controls were determined and the detection results were performed the comparative analysis.Results The serum BNP and UA levels in the observation group were significantly higher than those in control group with statistical difference between them(P <0.05),the serum BNP and UA levels were in turn progressively incereased as the cardiac function deterioration from NY-HA Ⅱ to NYHA Ⅳ,the differences from each other had statistical significance (P<0.05).The correlation analysis found that ser-um BNP level had good positive correlation with the cardiac functional grading,at the same time,serum UA level was also positively correlated with the cardiac failure severity.The further analysis found that serum BNP level in the acute left heart failure was sig-nificantly higher than that in the chronic heart failure and serum UA level also had the same results(P <0.05),serum BNP level in the left heart failure relief was significantly decreased and serum UA level was also significantly decreased.Conclusion Serum BNP and UA levels are correlated with the heart failure severity.Dynamic monitoring serum BNP and UA levels in the patients with heart failure is helpful to judge the heart failure severity.

OBJECTIVE:To investigate the association of Cytochrome P4503A family polypeptide 5 [(CYP)3A5] and IL-10 poly-morphisms with the concentration/dose(C/D) ratio of tacrolimus in lung transplantation recipients. METHODS:CYP3A5 polymor-phisms at rs774746 and IL-10 polymorphisms at rs1800896 from peripheral blood cell of 51 lung transplant recipients was detected by Se-quenom MassArray iPLEX GOLD system. The relationship between gene polymorphism and tacrolimus C/D ratio was analyzed. RE-SULTS:The tacrolimus C/D ratio of the recipients who carried CYP3A5 rs776746 GG genotype were higher than those with AA+GG genotype,with statistical significance(P<0.01). The tacrolimus C/D ratio of the recipients who carried IL-10 rs1800896 AA genotype were higher than those with AG genotype during 1 week and 2 weeks after transplantation,with statistical significance(P<0.05). Com-bined analysis of these two genes,the tacrolimus C/D ratio of the recipients who carried more fast metabolic alleles were higher than those who didn't carry fast metabolic alleles,with statistical significance(P<0.01). CONCLUSIONS:Determination of recipients CYP3A5 at rs 776746and IL-10 at rs800896 genotype may be performed prospectively to help individualizing tacrolimus dose regimen.

Objective To study the expression of phosphorylated myosin light chain kinase(P-MLCK) in human pulmonary arterial endothelial cell(HPAEC) induced by lipopolysaccharide(LPS). Methods HPAECs were cultured in vitro and treated with LPS(2 ?g/mL) and normal saline for 1 h,respectively.Immunofluorescence method and western blotting were used to detect P-MLCK. Results Compared with normal saline group,the number of HPAECs decreased,but the morphology of cells did not change.After treatment of LPS for 30 and 60 min,the expression of P-MLCK in HPAEC increased from 0.41?0.05 to 0.82?0.43 and 1.56?0.07,respectively(P
