The integrated metabolomics and proteomics results suggested that QZYSD may improve IVF outcomes in AMA infertility primarily by regulating the expression of component C8 alpha chain (C8A), carboxypeptidase B2 (CPB2), serum paraoxonase/arylesterase 1 (PON1), immunoglobulin heavy variable 3-9 (IGHV3-9) and pantetheinase (VNN1), as well as influencing the protein digestion and absorption and pantothenate and coenzyme A biosynthesis pathways. The gene discussed is VNN1; the disease is Infertility.
