背景:胰岛素抵抗与小肠黏膜通透性的关系可能与脂肪过多、炎症和氧化应激等有关。目前不同种类的运动对该关系的影响尚不清楚,还需要进一步进行相关机制研究。目的:以高脂饲料诱导胰岛素抵抗小鼠模型,观察不同形式的长期运动(持续运动和累积运动)对胰岛素抵抗小鼠肠黏膜通透性的影响,并比较不同运动强度的效果差异,以评价累积运动的健康促进效应。方法:采用4周龄雄性C57BL/6J小鼠,以高脂饲料诱导胰岛素抵抗小鼠模型,造模成功的小鼠随机分为5组,分别为高脂胰岛素抵抗组、普食胰岛素抵抗组、中强度持续运动组、中强度累积运动组、高强度累积运动组,其中高脂胰岛素抵抗组饲以高脂饲料,其余各组饲以普通饲料。各运动组接受8周的不同形式的跑台训练:中强度持续运动组小鼠进行50 min,速度为11 m/min的运动;中强度累积运动组小鼠进行每天4次,每次12.5 min(次与次间隔3 h),速度为11 m/min的运动;高强度累积运动组小鼠进行每天4次、每次7.5 min(次与次间隔3 h),速度为19 m/min的运动。末次运动48 h后取材,检测各组小鼠血清中的脂多糖和右旋乳酸含量,采用苏木精-伊红染色观察回肠组织病理变化,通过Western blot法检测肠道紧密连接蛋白的表达,ELISA法测定血液和回肠组织中的炎症因子白细胞介素10、肿瘤坏死因子α及肠道黏膜分泌性免疫球蛋白A的表达。结果与结论:①高脂膳食诱导的胰岛素抵抗小鼠伴有体质量增加、血清内毒素和右旋乳酸水平显著升高、血清和小肠组织促炎因子肿瘤坏死因子α水平显著增加等表现;长期规律性的累积运动和持续运动均可降低胰岛素抵抗小鼠的体质量,并明显改善糖代谢功能,纠正或改善胰岛素抵抗症状;②长期规律性的累积运动和持续运动均可提高肠黏膜组织中紧密连接蛋白的表达量并增加分泌性免疫球蛋白A分泌量,从而改善肠黏膜通透性,增强肠道免疫功能,降低血清中内毒素脂多糖的含量,进而降低循环血和肠组织中的促炎症因子表达,最终发挥对胰岛素抵抗小鼠肠黏膜屏障的保护作用;③等运动量的高强度累积运动与中强度累积运动、中强度持续运动相比,在降低胰岛素抵抗小鼠的体质量、改善胰岛素抵抗症状、保护肠黏膜屏障方面效果更明显。

The stimulating effect of rhizosphere on denitrification is considered to be an unavoidable loss of soil nitrogen（N） and detrimental to crop N use efficiency,which is regulated by crop growth and soil properties. Soil acidification, occurring rapidly in many intensive farming lands, affects both crop growth and soil properties, thereby altering rhizosphere effect on denitrification. However, the mechanism by which soil acidification regulates rhizosphere denitrification still remains unclear. Here, we determined the denitrification capacity（DC） and associated community compositions of nirK-and nirS-type denitrifiers in maize rhizosphere and bulk soils at four acidity gradients（pH = 6.8, 6.1, 5.2, and 4.2）. Results showed that the stimulating effect of rhizosphere on DC strongly depended on soil pH. Compared to bulk soil, rhizosphere soil had significantly higher DC at pH 5.2, but not at pH of 4.2. With increasing soil acidity, the stimulation of rhizosphere on DC（calculated as the difference in DC between rhizosphere and bulk soils） decreased from 8.01 to 0.01 mg N ***, soil acidification significantly reduced the differences in dissolved organic carbon（DOC） and abundance of key nirK-type denitrifier taxa between rhizosphere and bulk soils, both of which were positively related to the stimulation of rhizosphere on DC. These findings demonstrated that soil acidification could weaken the positive rhizosphere effect on denitrification via regulated C availability and associated nirK-type denitrifier community, potentially reducing N loss risk in rhizosphere soil. The independent role of soil p H should be fully considered when modelling N behaviour in plant-soil systems.
