Simvastatin decreased the apoptosis of neurons in the intracerebral hemorrhage animals. (A) A TUNEL assay and the quantified apoptotic rate indicated a reduced rate of apoptosis in simvastatin-treated animals. (B) Western blot analysis of the expression levels of AQP4, MMP-9, caspase-3 and Bcl-2 in neuronal cells in experimental mice. Simvastatin treatment significantly downregulated the expression levels of AQP4, MMP-9 and caspase-3. Whereas it significantly upregulated the protein expression of Bcl-2. **P<0.01. AQP4, aquaporin-4; MMP-9, matrix metallopeptidase 9; Bcl-2, B-cell lymphoma-2.
