a Volcano plot of the gene expression profiles in the Ph-positive group and b differentially expressed genes (compared with T0) subjected to hierarchical clustering analysis. a In the volcano plot, the -log10(P value) is plotted on the y-axis, and the log2 ratio of the fold change is plotted on the x-axis. Forty-seven genes (red points) that exhibited fold-changes of 20.4 = 1.320 (p < 0.01) were selected from the 1852 filtered genes. b In the cluster plot, each column represents a chip, and each row represents a specific gene. Most genes were down-regulated (45/47 genes) among the differentially expressed genes after herbal plaster treatment. The genes involved in pathway are indicated with arrows
