目的研究复合全谷豆粗杂粮抗氧化复合链对脂代谢异常人群氧化应激的影响。方法2008年3月至2009年3月,从南京市3个主城区采用多阶段分层随机抽样抽得418例常住汉族(45~75岁)高脂血症患者,按准实验设计,根据社区、血脂和氧化指标分层随机分为干预组(212例)与对照组(206例)。干预组给予粗杂粮干预和健康教育,对照组仅给予健康教育。干预周期为1年,干预前后各进行1次医学体检,测量计算BMI、腰臀比(WHR);检测血脂以及血清总抗氧化能力(T—AOC)、丙二醛(MDA)、超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH—Px)等氧化应激指标。分析干预前后体态、生化指标与氧化应激指标的关联。结果干预后干预组的BMI[(25.53±2.77)kg/m2]、WHR(0.82±0.03)、TC[(4.60±0.98)mmol/L]、TG[(1.26±0.88)mmol/L]低于对照组[(26.60±3.18)kg/m2、0.93±0.05、(4.97±1.02)mmol/L、(1.98±1.11)mmol/L](P值均〈0.05);而HDL—C[(1.34±0.26)mmol/L]高于对照组[(1.18±0.17)mmol/L](P〈0.05);干预后干预组的T—AOC(19.52±0.81)、SOD[(85.42±21.65)U/ml]、GSI-I—Px[(128.26±33.65)umol/L]高于对照组[11.11±1.30、(78.68±30.48)U/ml、(118.48±24.19)umol/L](P值均〈0.05);而MDA[(1.78±1.16)nmol/ml]低于对照组[(2.12±1.37)mmol/L](P〈0.05);T-AOC与TC、TG及BMI呈负相关(r值分别为-0.258、-0.266、-0.230,P值均〈0.05),与HDL—C呈正相关(r=0.194,P〈0.05);SOD与TC、TG、BMI呈负相关(r值分别为-0.282、-0.311、-0.217,P值均〈0.05),与HDL—C呈正相关(r=0.169,P〈0.05)。结论复合全谷豆粗杂粮膳食干预明显改善脂代谢异常人群的代谢状况。人体常用代谢指标和体内氧化应激反应水平存在关联?
Objective To explore the influence of compound whole grain complex antioxidant chain on oxidative stress to the hyperlipidemia population. Methods From March 2008 to March 2009,418 hyperlipemia residents (45 to 75 years of age) of Han group were screened from 3 main districts in Nanjing, according to the community, blood lipids and oxidative indicators, stratified into intervention and control group by quasi-experimental design. The intervention group (212 individuals )were provided with compound whole grain and health education while only health education was provided for the control group (206 individuals). Body mass index ( BMI ), waist-to-hip ratio ( WHR ), total cholesterol ( TC ), triglyceride (TG) and high density lipoprotein cholesterol ( HDL-C ) and oxidative indicators ( including T-AOC, MDA, SOD, GSH-Px ) were measured before and after the one-year intervention period. Analyses of the correlation between posture, biochemical markers and oxidative stress indicators before and after intervention were carried out. Results After intervention, BMI ( ( 25. 53 ± 2. 77 ) kg/m2 ), WHR ( 0. 82 ± 0. 03 ), TC ( ( 4. 60 ± 0. 98 ) mmol/L) ,TG( (1.26 ±0. 88)retool/L) in the intervention group were decreased significantly compared to the levels of BMI((26.60 ± 3.18 ) kg/m2),WHR(0.93 ±0.05),TC((4.97 ± 1.02) mmol/L),TG ((1.98± 1.11) mmol/L) in the control group (all P values 〈 0.05); while HDL-C ((1.34 ± 0. 26)mmol/L) in the intervention group was increased significantly compared to tbe level of HDL-C (( 1.18 ± 0. 17)mmol/L) in the control group (P 〈 0. 05 ) ; After intervention, levels of T-AOC (19.52 ± 0.81),SOD ((85.42 ±21.65) U/ml) and GSH-Px ((128.26 ±33.65) umol/L) were increased significantly compared to the levels of T-AOC( 11.11 ± 1.30) , SOD( (78.68 ± 30. 48 ) U/ml) and GSH-Px ((118.48±24.19) umol/L) in the control group(all P values ?
