The effect of Danshen, Safflower and Danhong on the network of chronic stable angina. (A) The network of chronic stable angina, the red nodes represent chronic stable angina related genes and the grey nodes represent their first-order neighbors. (B) The related gene of Danshen, Safflower and Danhong mapping to the network of chronic stable angina, the blue, pink and purple nodes represent Danshen, Safflower and Danhong related genes, respectively. (C) The comparison of signaling pathway among the network of Danshen, Safflower and Danhong injection.
