摘要:

背景:代谢综合征对人体的危害极大,且受到多种因素的影响。通过构建饮食诱导动物模型,可以更好的分析营养因素和代谢综合征之间的关系,为临床治疗等提供可靠的参考依据。

目的:构建高脂饮食喂养肥胖小鼠模型,探讨营养因素和代谢综合征的关系。

方法:选择30只小鼠随机分为模型组20只和对照组10只,分别予以高脂饮食纯化饲料和普通饲料喂养,连续喂养10周。

结果与结论:与对照组相比,高脂饮食纯化饲料喂养后1周,模型组小鼠即出现体质量升高,且随着喂养时间增加呈现出差异逐渐增大的情况;喂养后8周,模型组的体质量指数和显著升高(P < 0.05)。喂养后4周,模型组的空腹静脉全血血糖即显著升高,且随着喂养时间的增长呈现出逐渐上升的情况;喂养后5周,模型组的空腹胰岛素水平也开始出现升高;经口服糖耐量实验,随着喂养时间的增长,模型组小鼠表现出糖耐量逐渐下降的趋势;喂养后8周,模型组的血清总胆固醇、高密度脂蛋白胆固醇水平均出现显著性上升高(P < 0.05);喂养后10周,模型组的三酰甘油、血清总胆固醇、低密度脂蛋白胆固醇和高密度脂蛋白胆固醇均升高(P < 0.05)。结果证实,实验成功构建了高脂饮食喂养肥胖小鼠模型,可能模拟人类的代谢综合征的自然发病过程,且营养因素与代谢综合征密切相关。

Abstract:

BACKGROUND: Metabolic syndrome greatly harms the human body, and is affected by many factors. Through constructing diet-induced animal models, we can better analyze the relationship between nutritional factor and metabolic syndrome, and provide reliable references for the clinical treatment of this disorder.

OBJECTIVE: To construct obese mouse models with high-fat diet feeding and discuss the relationship between nutritional factor and metabolic syndrome.

METHODS: Thirty mice were selected and randomly divided into model group (n=20) and control group (n=10), and were fed with high-fat and normal animal feeds for 10 consecutive weeks.

RESULTS AND CONCLUSION: Compared with the control group, after 1 week of feeding with high-fat animal feeds, body weight of mice in the model group raised, and differences gradually increased with the feeding time increased. After 8 weeks of feeding, body mass index of mice in the model group significantly raised (P < 0.05). After 4 weeks of feeding, fasting venous blood glucose level of mice in the model group significantly raised, and showed a gradual rise trend with feeding time. After 5 weeks of feeding, fasting insulin level of mice in the model group also began to rise. The oral glucose tolerance test showed that mice in the model group showed a gradual downward trend of glucose tolerance with feeding time. After 8 weeks of feeding, serum levels of total cholesterol and high density lipoprotein cholesterol in the model group significantly raised (P < 0.05). After 10 weeks of feeding, serum levels of triacylglycerol, total cholesterol, low density lipoprotein cholesterol and high density lipoprotein cholesterol in the model group raised (P < 0.05). The results demonstrate that obese mouse models were successfully constructed with high-fat diet feeding, which can simulate the natural progression of metabolic syndrome in human, moreover, the nutritional factor is closely related to metabolic syndrome.
