Expression level of Bax protein in diabetes + SAH group (0.678 ± 0.124) was significantly higher than that in the blank control group (0.306 ± 0.086) and diabetes group (0.394 ± 0.098) (P < 0.05); and expression level of Bcl-2 protein in diabetes + SAH group (0.517 ± 0.062) was significantly higher than that in the blank control group (0.337 ± 0.116) and diabetes group (0.372 ± 0.185) (P < 0.05) (Figure 5). This evidence concerns the gene BAX and diabetes mellitus.
