【Abstract】 Premature rupture of fetal membranes is an important obstetrical complication, but its cause and mechanism are still not well-known. More and more evidences have suggested that development of premature rupture of fetal membranes relates to changes in structure of fetal membranes. Matrix metalloproteinases are a group of enzymes that can degrade extracellular matrix macromolecules, including collagens. They disrupt the helix of collagens and control content of extracellular matrix and formation of fetal membrane structure. So matrix metalloproteinases are associated with development of premature rupture of membranes closely.更多还原
