MicroRNA profiling of the intestine during hypothermic circulatory arrest in swine

Figure 1 Histopathological changes in the mucosa in each group. A: Epithelial layer and the lamina propria of the intestinal mucosa in the SO group were normal; B: Shortened and irregular villi as well as subepithelial space were observed; some lifting of the epithelial layer of the lamina propria was observed in mucosa exposed to HCA (magnification × 200).

Figure 2 Heat maps of the differentially expressed microRNAs. Twenty-five dysregulated microRNAs were detected between the HCA and SO groups (P < 0.05) in this study. HCA: Hypothermic circulatory arrest; SO: Sham operation.
