Behavioral assays. (a) Open-field test. (b) Sucrose-preference test. For all assays, testing was performed both before model building and after model building. Moreover, the following groups were analyzed: (1) the control/normal group (white), (2) model group (black), (3) Shuyu capsule group (gray), and (4) positive-control fluoxetine group (charcoal gray). The statistical analysis for the behavior assays was performed by one-way ANOVA (n = 18, ^∗ P < 0.05, ^∗∗ P < 0.01, and ^∗∗∗ P < 0.001).
