Advances in the research of Matrix Metalloproteinases and the mechanisms of inflammatory endometrium hemorrhage and its repairing

Matrix metalloproteinases(MMP) and Tissue Inhibitor of metalloproteinases(TIMP) can regulate the degradation and synthesis of extracellar matrix(ECM), and participate in many physiogical and pathological processes in vivo.They play important roles in periodical reconstruction of endemetrium.The unbalance of them are close by related to inflammatory endometrium hemorrhage and repairing.
