The hormone levels, factors associated with endometrial bleeding, oxidative stress, and apoptotic proteins in the endometrium, were then investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The results demonstrated that 540\u2009mg\/kg lithospermum plus 1\u2009mg\/kg mifepristone treatment significantly improved the abortion rate when compared with the control group. Compared with the 1\u2009mg\/kg mifepristone, 540\u2009mg\/kg lithospermum plus 1\u2009mg\/kg mifepristone treatment did not induce significant increase in factors associated with abnormal endometrial bleeding, such as matrix metalloproteinase\u20109 (MMP9). However, mifepristone and lithospermum combination regimen promoted the expression level of malondialdehyde (MDA), activated caspase 3, caspase 9 and Bax, meanwhile, reduced the expression of superoxide dismutase (SOD) and Bcl\u20102.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These findings provided strong evidence that mifepristone and lithospermum
