Résumé
Objective To investigate the association betweenserum nitric oxide and microalbuminuria.Methods Based on a community survey in Jinchang district Suzhou city,a 1 ∶ 2 matched case-control study was performed.A total of 208 cases with microalbuminuria were recruited.The controls were selected from the same community,with the same level of income.After matched with age,gender,waist circumference and fast plasma glucose,a total of 416 controls were selected.Values of serum nitric oxide were tested for all eligible participants.The association between serum nitric oxide level and microalbuminuria were analyzed by using the multivariate conditional logistic regression models.Results The mean level of serum nitric oxide was slightly lower for individuals with microalbuminuria (median,interquartile range:27.75,14.48-42.15 μmol/L) than those without (28.25,17.40-43.45 μ mol/L ).However,the difference was not statistically significant (P=0.316).Results from the multivariable conditional logistic regression model showed that serum nitric oxide level was not associated with microalbuminuria,after adjustment for all the confounders.Compared with the highest level of serum nitric oxide,the odds ratios of microalbuminuria for individuals in the 1 st,2nd and 3rd quartiles were not significantly different,after adjustment for confounders.In pairs with hypertension,the odds of microalbuminuria were 85％ higher for individuals with the lowest level of serum nitric oxide than those with the highest level (OR=1.85,95％ CI:0.96-3.57).Additionally,in pairs without hypertension,the odds of microalbuminuria was just 40％ higher for individuals with the lowest level of serum nitric oxide than those with the highest level (OR=1.40,95％CI:0.58-3.40).Conclusion There was no significant correlation between serum nitric oxide and microalbuminuria in the general population in our study.
Résumé
Objective To explore the relationship between interleukin (IL)-10 gene polymorphisms and the susceptibility or the outcomes of HCV infection among high-risk populations in Jiangsu province.Methods IL-10 gene SNPs were detected in 1555 subjects including 264 self-limited HCV infections.371 persistent HCV infections and 920 healthy controls were selected through Taqman-MGB.Results After adjusted for cofounders as sex,age and high-risk population,data from logistic regression analysis showed that the distribution of IL-10 genotypes among the controls,spontaneous clearances and those with persistent infections did not show much differences.Results from further stratified analysis showed that,at the position of-819T/C,when compared with TT genotype,TC genotype had a significantly increasing chance of self-limited HCV infection among middle-aged,females and paid blood doners (adjusted OR values and 95％ CI were:2.160,1.163 4.011 ；1.693,1.066-2.688 and 4.084,1.743-9.570).It also had a lower risk of progressing to persistent HCV infection among those paid blood doners (the adjusted OR values and 95％CI were:0.312,0.130-0.747 ).CC genotype had a higher chance of self-limited HCV infection among people underwent blood dialysis (the adjusted OR values and 95％CI were:2.120,1.071 -4.197).Results also showed a decreased risk of progressing to persistent infection among paid blood doners (the adjusted OR values and 95％CI were:0.156,0.043-0.566).At the position of -592A/C,when compared to AA genotypc,the AC genotype had a significantly increasing chance of self-limited HCV infection among middle-aged,femalcs and paid blood doners (the adjusted OR values and 95％ CI were:2.176,1.173-4.037；1.659,1.055-2.607;3.704,1.625-8.443) but had an increased risk of persistent HCV infection among females (the adjusted OR values and 95％CI were:1.525,1.017-2.286).AC genotype showed an increased opportunity to progress to HCV persistent infection among drug users (the adjusted OR values and 95％CI were:1.845,1.122-3.034) but had a reduced risk of progressing to HCV persistent infection among paid blood doners (the adjusted OR values and 95％CI were:0.361,0.155-0.841 ).CC genotype had an increased opportunity to self-linited HCV infection as well as having a dccreased risk of progressing to persistent infection among paid blood donets (the adjusted OR values and 95％CI were:3.125,1.016-9.605；0.218,0.063-0.748).At the position of-1082A/G,AG/GG genotypcs had an increased chance of self-limited infection among blood doners (the adjusted OR values and 95％CI were:3.780,1.620-8.820).Conclusion IL-10-819T/C,-592A/C,-1082A/G SNPs might be related with the susceptibility and the outcomes of HCV infection among populations at high risk.
