groups (11.025,  22.05,  44.10  g/kg),  with  10  rats  in  each  group.  Each  group  was  given  distilled  water/corresponding  medicinal
          solution intragastrically, once a day, for 12 consecutive days. Except for normal group, other groups were given traditional Chinese
          medicine  for  warming  yang  and  mifepristone  to  establish  a  model  of  spontaneous  abortion  with  heat  syndrome.  24  h  after  the  last
          medication,  serum  levels  of  triiodothyronine (T3),  thyroxine (T4),  interleukin-2 (IL-2),  IL-4,  IL-6,  IL-10,  and  interferon-γ
         (IFN-γ)  were  all  detected;  the  abortion  rate  and  uterine  coefficient  were  calculated;  the  pathological  morphology  of  the  pregnant
          uterus  was  observed;  protein  expressions  of  NLRP3, ASC  and  caspase-1  were  detected.  RESULTS  The  molecular  docking  results
          showed that the binding energies of 13 main components of Pangshi antai zhixue decoction with NLRP3, ASC, and pro-caspase-1
          were all less than -5 kJ/moL. The animal experiment results showed that compared with normal group, the uterine coefficient and
          serum levels of IL-4, IL-6 and IL-10 were decreased significantly in model group (P<0.05); the abortion rate and serum levels of
          T3,  T4,  IL-2  and  IFN-γ  as  well  as  protein  expressions  of  NLRP3, ASC  and  caspase-1  were  increased  significantly (P<0.05);
          there  were  abortion  lesions  in  the  pregnant  endometrium.  Compared  with  the  model  group,  most  of  the  quantitative  indicators
          mentioned above were significantly reversed in Pangshi antai zhixue decoction groups (P<0.05), and the endometrial miscarriage
          lesions  in  pregnancy  were  improved  to  varying  degrees.  CONCLUSIONS  Pangshi  antai  zhixue  decoction  influences  the  immune
          balance  between  mother  and  fetus  by  regulating  the  formation  of  NLRP3  inflammasome,  down-regulating  pro-inflammatory
          cytokines such as IFN-γ and IL-2, and up-regulating anti-inflammatory cytokines such as IL-4, IL-6 and IL-10, thereby improving
          spontaneous abortion with heat syndrome.
