changes  in  the  corresponding  organs  were  observed,  and  blood  routine  and  serum  biochemical  indicators  were  measured,  in  order
          to  assess  the  subacute  toxicity  of  Shuangshu  decoction.  In  pharmacodynamic  experiments:  50  rats  were  divided  into  blank  control
          group,  model  group,  and  Shuangshu  decoction  low-,  medium-,  and  high-dose  groups (9.45,  18.9,  37.8  g/kg),  with  10  rats  in
          each  group.  Except  for  blank  control  group,  rats  in  all  other  groups  were  used  to  establish  the  FD  rat  model  by  subcutaneous
          injection  of  loperamide (3.5  mg/kg).  Rats  in  each  group  were  administered  the  corresponding  drug  solution/normal  saline
          intragastrically,  once  a  day,  for  14  consecutive  days. After  the  last  medication,  fecal  moisture  content,  intestinal  propulsion  rate,
          gastric  emptying  rate  and  serum  level  of  motilin  were  all  detected,  and  interstitial  cell  of  Cajal (ICC)  ultrastructure  of  rats  was
          observed in colon tissue. RESULTS The safety experiments showed that no death occurred in each dose group, and no significant
          difference was found in organ coefficient, routine blood and serum biological index, compared to blank control group (P>0.05);
          no  abnormality  was  found  in  organ  appearance  and  pathological  sections. The  results  of  the  pharmacodynamic  experiments  showed
          that,  compared  with  the  blank  control  group,  the  fecal  moisture  content,  gastric  emptying  rate,  intestinal  propulsion  rate,  and
          serum motilin levels in the model group were significantly decreased (P<0.05); in the colonic tissue, the mitochondria in the ICC
          exhibited  severe  swelling  with  the  disappearance  of  cristae,  and  the  endoplasmic  reticulum  was  dilated.  Compared  with  model
          group,  the  rats  in  Shuangshu  decoction  high-dose  group  showed  significant  increases  in  the  above  quantitative  indicators (P<
          0.05);  additionally,  there  was  a  large  number  of  mitochondria  in  the  ICC  of  the  colonic  tissue,  with  clear  cristae  and  regular
          arrangement.  CONCLUSIONS  Shuangshu  decoction  is  safe  and  has  a  beneficial  improving  effect  on  FD  rats;  its  mechanism  of
          action may be related to the regulation of gastrointestinal hormone expression to promote gastric emptying and intestinal propulsion,
          as well as the repair of mitochondrial structure in ICCs to restore gastrointestinal function.
