          ABSTRACT    OBJECTIVE  To  investigate  the  mechanism  of  Fuke  duanhongyin  capsule  in  improving  dysfunctional  uterine
          bleeding (DUB)  in  rats.  METHODS  Pregnant  SD  rats  were  randomly  divided  into  blank  control  group (distilled  water),  model
          control  group (distilled  water)  and  Fuke  duanghongyin  capsule  group (1.296  g/kg),  with  6  rats  in  each  group.  Except  for  blank
          control  group,  DUB  model  was  established  in  other  groups. After  modeling,  they  were  given  relevant  medicine/distilled  water  10
          mL/kg intragastrically, once a day, for consecutive 14 d. After medication, uterine index, ovary index and hemorheology indexes
         (whole blood high shear relative index, whole blood low shear relative index, erythrocyte aggregation index, Carson viscosity) of
          rats  were  all  determined. The  pathological  changes  of  uterus  and  ovary  tissues  were  observed;  mRNA  relative  expression  levels  of
          epidermal  growth  factor (EGF),  hypoxia-inducible  factor  1α (HIF-1α),  epidermal  growth  factor  receptor (EGFR)  and  serine/
          threonine-protein  kinase  1(AKT1),  and  protein  relative  expression  levels  of  EGF  and  EGFR  in  uterine  tissue  were  all  measured.
          RESULTS  Compared with model control group, the uterine index, ovary index, erythrocyte aggregation index were all decreased
          significantly in Fuke duanghongyin capsule group (P<0.05 or P<0.01); whole blood high shear relative indexes, mRNA relative
          expression  levels  of  EGF,  HIF-1α  and  EGFR  and  protein  relative  expression  levels  of  EGF  and  EGFR  in  uterine  tissue  were  all
          increased significantly (P<0.05 or P<0.01). The pathological changes of ovary and uterus were improved. CONCLUSIONS Fuke
          duanhongyin  capsule  can  improve  DUB  in  rat,  the  mechanism  of  which  may  be  related  to  the  activation  of  EGF-EGFR  signaling
          pathway.
