摘要:

目的 研究氯化钙干预下高脂饮食小鼠的体质量、血脂、血糖、LPS 指标变化,应用16S rRNA高通量测序技术检测氯化钙干预下高脂小鼠肠道菌群变化,探索氯化钙通过调节肠道微生物组成对高脂肪饮食诱导的小鼠肥胖的影响。方法 将 30 只雄性 C57BL/6 野生型小鼠随机分为对照组(C)、模型组(M)、氯化钙处理组(D),每组 10 只。C 组喂标准饲料和饮用水,M 组喂高脂饲料和饮用水,D 组喂高脂饲料和 1.5 g/100 mL 氯化钙。连续喂养 11 周,11 周后采样。比较不同组小鼠体质量、血脂、血糖、LPS、肠道菌群变化。结果 氯化钙能显著抑制高脂饮食 C57BL/6J 小鼠的体质量增加。氯化钙自由饮水 11 周后,D 组与 M 组相比,D 组水平 TC 降低,血糖降低,炎症因子 IL⁃1β、IL⁃6 降低,IgM 升高,IgG 升高,脂多糖降低,并通过分析氯化钙干预下高脂饮食小鼠肠道菌群的变化,发现氯化钙能调节高脂饮食介导的肠道菌群紊乱。结论 氯化钙能够调节肠道微生物组成改善高脂肪饮食诱导小鼠的肥胖。

Abstract:

Objective To study the changes in body weight,blood lipids,blood sugar and LPS of miceon a high⁃fat diet under the intervention of calcium chloride,use 16S RNA high⁃throughput sequencing technologyto detect changes in the intestinal flora of high⁃fat mice,and explore the effect of calcium chloride on obesity in themice by regulation the composition of gut microbes. Methods Thirty male C57BL/6 wild⁃type mice were randomlydivided into control group(C),model group(M),and calcium chloride treatment group(D),10 in each group.Groups C,M and D were fed with standard feed plus drinking water,high⁃fat feed plus drinking water,and high⁃fat feed plus 1.5 g/100 mL calcium chloride for 11 weeks,followed by collecting the samples. The changes in bodyweight,blood lipids,blood sugar,LPS,and intestinal flora of different groups of mice were compared among thegroups. Results Calcium chloride significantly inhibited the weight gain of C57BL/6J mice on a high ⁃fat diet.After 11 weeks treatment with calcium chloride plus drinking water,the levels TC and blood sugar were significantlylowered,inflammatory factors IL⁃1β and IL⁃6 significantly decreased. IgM significantly increased,IgG significantlyincreased,and lipopolysaccharide significantly decreased in group D,as compared with group M. Calcium chlorideimproved the lipid disorders in the high⁃fat diet mice. Conclusion Calcium chloride can adjust the composition ofintestinal microbes so as to improve obesity in mice induced by high⁃fat diet.
