Comparison of the expression of a key unfolded protein response (UPR) protein, glucose-regulated protein 78 (GRP78). (a) The immunohistochemical expression of the key UPR protein GRP78 (200×). (b) Comparison of GRP78 values expressed as the mean ± SD (n = 7). A: sham operation group; B: model group; C: low-dose Wenxin Granule group; D: high-dose Wenxin Granule group; E: metoprolol group. ∗P < 0.05, ∗∗P < 0.01 compared with the sham operation group, #P < 0.05, ##P < 0.01 compared with the model group.
