Objective To investigate whether caspase-8 regulates Bcl-2 expression in Fas and Actinomycin D(AD) induced apoptosis in Bel-7402 cells.Methods Bel-7402 cells were divided into four groups randomly,that is:control,Fas group,Fas-AD group and Ac-IEFD-cho group,and treated with Fas-AD in the presence/absence of caspase-8 inhibitor Ac-IEFD-cho.The expressions of caspase-8 and Bcl-2 were determined with Western Blot and RT-PCR,respectively.Results Compared with control group and Fas group,after Bel-7402 cells were treated with Fas-AD,typical apoptosis morphology was clearly observed,the expression of activated caspase-8 increased significantly,and the Bcl-2 expression decreased apparently.However,after Bel-7402 cells were treated with Fas-AD in the presence of the caspase-8 inhibitor Ac-IEFD-cho,the expressions of activated caspase-8 decreased while the Bcl-2 expression increased.Conclusion Activated caspase-8 can regulate Bcl-2 in Fas-and AD-induced apoptosis in Bel-7402 cells.

Objective To examine the change of TGF-?1 in the bloods of rats which were induced by tetrachoride during the different times and to explain the mechanism of the change.MethodsThe experimental liver fibrosis induced by tetrachloride in rats was treated by matrine compound injection.Serum TGF-?1 and pathological changes in liver tissue were observed in control group,model group and therapy group during the time of the 4th,6th and 9th week.ResultsThere was an obvious change of TGF-?1 in the blood in different time and different groups.ConclusionMatrine compound injection has an antifibrogenetic action and TGF-?1 can reflect the change of liver fibrogenesis of different time as an index.

A novel strain,which could use 2-hydroxypyridine (2HP) as the sole source of carbon,nitrogen,and energy,was isolated from petroleum-contaminated soil at the Liaohe estuarine wetland.Strain 2PR was identified as Arthrobacter based on the morphology and 16S rRNA gene sequence.The optimum growth and degradation condition upon 2PR is 30℃ and pH 7.0,respectively.Under this condition,2HP degradation rate were 97.34％,94.95％,94.48％ and 89.21％ with 2,4,6 and 8 mg/ml initial concentration of 2HP at 42,96,120 and 156 h,respectively.Strain growth and 2HP degradation kinetics studies indicated that the strain followed Logisitic model,which could provide a theoretical and technical reference for the biodegradation of 2HP.The color of strain 2PR culture upon 2HP-MSN changed from colorless to blue,and then turned to brown.The blue pigment,which was observed at the culture of strain 2PR,was identified as 4,5,4',5'-tetrahydroxy-3,3'-diazadiphenoquinone-(2,2') by high performance liquid chromatography (HPLC) and high-performance liquid chromatography-mass spectrometry (LC-MS) analysis.The LC-MS signal with m/z =249.1 was observed in resting cells reaction sample with 2HP as the substrate.The degradation of 2HP might be achieved by a dioxygenase to produce 2,3,6-trihydroxypyridine,which could transformed to the blue pigment spontaneously,and then 2,3,6-trihydroxypyridine was converted with an pyridine-ring cleavage reaction.Among all the reported strains,strain 2PR has the strongest tolerance and the highest 2HP degradation efficiency at present.The strain has a promising application potential for 2HP waste treatment.

Objective To investigate the application value of virtual touch tissues quantization(VTQ)in the stages of type 2 diabetic nephropathy.Methods 120 cases of type 2 diabetes were divided into 3 groups according to urinary albumin excretion rate (UAER):diabetes without urinary albumin,diabetes with trace albuminuria and diabetes with mass albuminuria.The control group consisted 30 normal cases.VTQ was used to measure the renal shear wave velocity (SWV),then compare were made between the 4 groups.Besides,correlation analysis was made between SWV and UAER in diabetic nephropathy group.Results When compared SWV,there was no significant difference between diabetes without urinary albumin and control group (P =0.144),but there was significant difference between each 2 group of diabetes with trace albuminuria,diabetics with mass albuminuria group and control group (P ＜ 0.05).There was also significant difference between each 2 group of diabetes (P ＜ 0.05).The correlation coefficients for SWV and UAER in diabetes were 0.697(P ＜0.05).ROC analyses showed the area under curves for SWV diagnosis for diabetic nephropathy was 0.93.The best cutoff point,sensitivity and specificity were 2.43 m/s,85.7％ and 84.5 ％,respectively.Conclusions The renal SWV increases as the renal injury progresses,which also plays an important role in diabetic nephropathy stages.

Objective To investigate the effects of 5-Aza-2'-deoxycytidine (5-Aza-CdR) on the apoptosis of A549/DDP cells and the expression of hMLH1 gene.Methods A549/DDP cells were treated with 5-Aza-CdR at 0.5,5,50 μmol/L.The growth curve of A549/DDP cells was investigated by MTT assay.The methylation status of hMLH1 gene was detected by methylation specific PCR (MSP).The expression of hMLH1 mRNA was evaluated by FQ-PCR.The apoptosis rate of A549/DDP cells was analyzed by flow cytometry.Results A549/DDP cells treated with 5-Aza-CdR showed a slow growth in comparison with the control cells,and the growth rates were decreased with the increasing of 5-Aza-CdR concentration.The apoptosis rate after treatment was higher than that before treatment in A549/DDP cells (P ＜ 0.05),and had a positive correlation with 5-Aza-CdR dose (P ＜ 0.001).hMLH1 mRNA expression level was increased in a 5-Aza-CdR concentration dependent manner (P ＜ 0.05).hMLH1 promoter in A549/DDP cells was methylated and hMLH1 mRNA was negatively expressed before treatment,but the mRNA was positively expressed after treatment with 5-Aza-CdR.Conclusions 5-Aza-2'-CdR can induce apoptosis of A549/DDP cells by inducing demethylation of hMLH1 promoter and thereby enhancing hMLH1 gene expression and its tumor suppressor function.
