 我注意到本文中处理方式不同的多张图片都存在图片重复的问题。具体说来：

• Figure 7H (H&E staining): Identical tissue sections appear mislabeled as distinct treatment groups: Spleen: 7-day control vs. 30-day control，7-day oral EUP-SeNP vs. 30-day oral EUP-SeNP group Kidney: 7-day control vs. 30-day oral EUP-SeNP group Colon: 7-day oral EUP-SeNP vs. 30-day oral EUP-SeNP group The duplicated regions (highlighted in attached annotations) demonstrate identical cellular architecture and staining artifacts.

• Figure 8C (IEC6 cell imaging): Merged fluorescence images labeled as "1-hour EUP-SeNP treatment" and "4-hour EUP-SeNP treatment" show spatial overlap of cellular structures , suggesting potential reuse of the same field of view.

鉴于明显的重复，我敦促作者提供解释和原始数据来澄清这个问题。
