RESUMEN
Objective To investigate the association between the peroxisome proliferator-activated receptor-or (PPARα) polymorphism rs1800206 (c.484C ＞ G,L162V) and the risk of metabolic syndrome (MES)Methods There were 1184 subjects aged 40-60 years recruited from our hospital between March 2010 and March 2011.The PPARα polymorphism 484C ＞ G was genotyped using TAQMAN assay by real-time PCR. The relationship between PPARα polymorphism and MES risk were investigated.Results The genotype frequencies were 91.4％,8.4％ and 0.2％ for the PPARα CC,CG and GG,respectively.This SNP was in Hardy-Weinberg equilibrium(P =0.845).Compared with the most common CC genotype,the variant genotypes(CG + GG) had higher fasting glucose((5.82 ± 1.59) mmol/L vs (5.49 ± 1.17) mmol/L,t =2.630,P =0.009) and LDL-C levels((3.53 ± 1.03) mmol/L vs (3.36 ± 0.65) mmol/L,t =2.376,P =0.018) and lower HDL-C levels ((1.56 ± 0.35) mmol/L vs (1.65 ± 0.43) mmol/L,t =2.430,P =0.015).Furthermore,the 484G variant genotypes(CG + GG)was associated with the risk of MES after adjusting for age,gender,education,BMI and lifestyle (smoking and alcohol status) (adjusted OR =1.89 ;95％ CI =1.09-3.23,P =0.012).Condusion PPARα polymorphism rs1800206 is a significant independent predictor of the MES in Southern Chinese.

Objective To investigate the association between the EPHX2 polymorphism G860A and the risk of hypertension in mild ages. Methods In a hospital based case-control study, one common polymorphism C860A in EPHX2 gene in a case-control study of 100 hypertension and 300 age- and sex frequency - matched disease-free controls were genotyped in a Southern Chinese population. SAS 9. 13 was used toanalysis the polymorphism and hypertension risk. Results Genotype frequencies of EPHX2 G860Alocus between the cases and the controls were significantly different (P =0. 01). Compared with the most common 860GG genotype, the 860GA heterozygote had an increased risk of hypertension (adjusted OR =1.98; 95%CI = 1.19 -3.51), the AA homozygote had a further increased risk of hypertension (adjusted OR =2. 84; 95%CI = 1.01 -6. 11). There was a significant trend for an allele dose effect on risk of hypertension (P trend = 0. 03). Conclusions EPHX2 polymorphism G860A is associated with an increased risk of hypertension, and the 860A variant may be a marker for susceptibility to hypertension.
RESUMEN
AIM: To explore the effect of pyrrolidine dithiocarbamate (PDTC), the specific inhibitor of NF-?B, on anti-thymocyte serum nephritis (ATSN) in rats. METHODS: The rat model of ATSN was reproduced with rabbit anti-thymocyte serum (ATS). The rats were divided into ATSN group, ATSN+PDTC group and control group. The expression of NF-?B p65 and the apoptosis, lysis as well as proliferation of mesangial cells (MC) were examined by immunohistochemical staining, Tdt-mediated X-dUTP nick end labeling (TUNEL), light microscope and electron microscope at 40 minutes, 24 hours and 7 days after injection of ATS or normal serum. RESULTS: The expression of glomerular NF-?B p65 in the ATSN group was observed with significant difference compared to controls at 40 min (P
RESUMEN
In this study the ability of the monoclonal anti-idiotypic antibody NP30 was tested as a substitute of diagnostic antigen in detecting antibody of Schistosoma japonicum from human sera by use of ELISA. The results showed that the seropositive rate was 98% with NP30 in the group of acute infection, which was comparable to 94% with gut associated antigens (GAA)and 98% with the soluble egg antigens (SEA); 87% with NP30 in the group of chronic infection which was comparable to 86% with GAA but lower than that of 98% with SEA. The false positive rate was about 3% for all three diagnostic antigens. The results also showed that the geometric mean titer (GMT) of antibody to NP30 was higher than that to GAA but lower than that to SEA in the acute infection group and the GMT of antibody to NP30 was lower than both those to GAA and to SEA in the chronic infection group,suggesting that the antibody to NP30 appeared earlier and decayed more quickly during the process of infection. The authors suggested that NP30 could be used for the diagnosis of schistosomiasis japonica.
