The main processes of XXMD in treating CIS include herpes virus infection pathway, cancer microRNAs, ovarian steroid hormones, NF-кB signaling pathway, Th17 cell differentiation pathway, HIF-1 signaling pathway, folate biosynthesis pathway, galactose metabolism, fructose and mannose metabolism, and so on, which are closely related to the signal pathways of CIS. This evidence concerns the gene HIF1A and in situ carcinoma.
