Kidney disease is a serious global health issue [1,2,3].
方法
All experiments using rats were approved by the Institutional Animal Care and Use Committee of Kanazawa Medical University (clearance number: 2017-59; approval date: 1 April 2017) and were conducted in accordance with the Institutional Animal Care and Use Guidelines (“Basic Guidelines for the Conduct of Animal Experiments” and “Basic Guidelines for Animal Care Management”).；Male Wistar rats (11 weeks old; n = 20) were obtained from SLC Japan, Inc.；After 1 week of acclimation, the rats were randomly divided into two groups (control and HFCS, n = 10 animals each).；The animals were housed individually and had ad libitum access to a standard feed (Labo MR stock, Nosan, Japan) and commercially available water (Évian-les-Bains, France).
核心结论
Quantitative analysis confirmed that argpyrimidine-positive areas were higher in the HFCS group than in the control group (mean score: 12.1% vs.；Although p62 immunoreactivity showed a similar staining pattern, it appeared lower in the HFCS group (15.8%) than in the control group (24.1%); however, the difference was not statistically significant. ‖ 结论：We found that HFCS intake was associated with increased argpyrimidine immunoreactivity in the kidneys of healthy Wistar rats, particularly in renal tubular epithelial cells, suggesting that GA- and/or MG-derived intracellular AGEs may accumulate before overt renal injury develops.
局限
Following HFCS intake, rats were exposed to glucose and fructose.；Although GA may be generated from these sugars, the amount generated remains unclear.；It may have been lower than the amount added to HK-2 cells in the in vitro experiments, but this issue was not resolved in the present study.

本文核心结论来自动物模型或体外细胞学，属临床前证据，不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义，与人类临床结局之间仍有距离。
