A two-factor, mixed-design ANOVA was used to evaluate the differences between and within the groups. An asterisk (*) indicates the change of the index is significant (p < 0.05); a pound sign (#) indicates the difference of the change between groups (compare with C group) is significant (p < 0.05); a $ indicates the difference of the mean value between groups (compared with C group) is significant (p < 0.05).
