The heat map. Each line is a sample dimension and each row is a genes dimension. The tree on the upper side represents the similarity settlement between samples, and the tree on the left represents the similarity settlement between genes. Red indicates increased, green indicates decreased, and color brightness is directly related to change in level of expression. The heat map shows that a total of 3162 proteins were identified and 96 of the 3162 secreted proteins identified in the ICH 24-h group were significantly differentially expressed from those in the control group (P < 0.05); of these proteins, 57 proteins increased while 39 decreased in abundance
