ABSTRACT
Objective To study the role of ERK1/2 signaling pathways on the process of ACA positive abortion and explore the effect of Anziheji on ERK1/2 signaling pathways from cell proliferation.Methods Levels of ERK1/2 on maternal-fetal interface of every mice in ACA positive abortion model group,blank control group,Anziheji low,mediate,high dose group,aspirin group were detected by immunohistochemical. Results The average optical density value of ERK1 in Anziheji low dose group(0.678 ±0.097)was close to normal group(0.727 ±0.047),there was no significant difference between them.Compared with blank control group,the ERK1 average optical density value in model group(0.434 ±0.066),Anziheji dose group(0.613 ±0.041),high dose group(0.487 ±0.061)and aspirin group(0.551 ±0.056)were significantly lower,and the differences were all statistically significant(P<0.01).Compared with blank control group(0.708 ±0.038),the ERK2 average optical density values in model group(0.430 ±0.058), Anziheji low dose group(0.621 ±0.041),mediate dose group(0.562 ±0.047),high dose group(0.449 ±0.062)and aspirin group(0.515 ±0.045) were significantly lower,and the differences were all statistically significant (P <0.01 ).Conclusion Anziheji can improve the activity of cell proliferation,improve the function of the placenta and change the outcome of pregnancy through ERK signal pathway.
