A significant difference in APC-R-positive rate was found (P<0. 01 ) between control group and experimental group, with the rate being 5 % in the controls and 25. 5 % in the experimental group. And the APC-R-pos- itive rates in the patients with only twice abortions and the patients over-3-time abortions were 22. 6 % and 29. 2 %, respectively (P>0. 05). The APC-R-positive rate, which was 37. 9 % in the patients of late abortion, was much higher than that in the patients of early abortion.
