title: [Effects of Shoutai Wan on proteome in decidua tissues of recurrent abortion mice].
abstract: OBJECTIVE
  To analysis the differential expression of decidua tissue proteins and effective mechanisms of recurrent abortion mice with Shoutai Wan, and explore the mechanism of Shoutai Wan in preventing miscarriage.
  
  
  METHODS
  The abortion-prone CBA/J x DBA/2 matings were established as the model of recurrent abortion and the nonabortion-prone CBA/J x BALB/c matings were used as the model of normal pregnancy. The model of recurrent abortion CBA/J x DBA/2 of mice pregnant were randomly divided into four groups according to the sequence of pregnancy, including model group, Shoutai Wan low-dose group, Shoutai Wan middle-dose group and Shoutai Wan high-dose group. From the 1st day of pregnant, mice of normal group, model group, Shoutai Wan low-dose group (3 g x kg x d(-1)), Shoutai Wan middle-dose group (6 g x kg x d(-1)) and Shoutai Wan high-dose group (12 g x kg x d(-1)) are oral administration in different doses. On the 14th day of pregnancy, all mice are killed and the embryo loss rate (ELR) was counted. The expression of differential proteins of mice decidua tissues were separated by means of 2-DE and identified by MALDI-TOF-MS. The functions of identified proteins were further analysed according to bioinformatics resources.
  
  
  RESULTS
  Compared with model group, low-dose Shoutai Wan can not significantly improve the model of recurrent abortion in pregnant mice ELR; Shoutai Wan middle-dose and high-dose group of pregnant mice ELR were significantly decreased (P < 0.01). The results showed that the well-resolved, reproducible 2-DE patterns of mice decidua tissues of model group, normal group and Shoutai Wan low middle high-dose group were obtained. Through comparative proteome analysis of decidua tissues of all groups, 30 differential expression protein spots which maybe related to recurrent abortion and Shoutai Wan intervention were identified by MALDI-TOF-MS. These differential expression proteins mainly refer to invasion of the blastocyst, blood vessel remodeling and cell apoptosis.
  
  
  CONCLUSIONS
  Shoutai Wan can decrease recurrent abortion mice ELR significantly, and play a role in preventing miscarriage. Recurrent abortion is a complicated process refer to diverse proteins participate. For several protein spots expression of decidua tissues in recurrent abortion mice was regulated by Shoutai Wan, it provides contribution to the effect characteristic of multitarget.
