Figure 4. Observation of myocardial autophagy in mice via electron microscopy and detection of GFP-LC3 puncta formation via fluorescence microscopy. (A) Control group and the sepsis group used electron microscopy to observe the autophagy result plot; (B) Fluorescence plot of GFP-LC3 spots in each group and expression of relative fluorescence intensity. **p < 0.01; ns p > 0.05.
