          过小鼠醋酸扭体实验评价大孔树脂流出部位和大孔树脂90%乙醇洗脱部位(给药剂量以生药量计均为2.4 g/kg)的止痛效果,并检
          测小鼠血清中肿瘤坏死因子α(TNF-α)、白细胞介素1β(IL-1β)、前列腺素E2 (PGE2 )、环氧合酶2(COX-2)水平。采用高效液相色
          谱-飞行时间质谱技术对灌胃大孔树脂90%乙醇洗脱部位后的小鼠血清进行原型成分及代谢产物鉴定。结果  大鼠体外实验中,
          以大孔树脂90%乙醇洗脱部位的解痉效果最好,其小肠张力抑制率显著高于大孔树脂流出部位(P<0.05),且与芍药甘草汤全方
          比较差异无统计学意义(P>0.05)。小鼠醋酸扭体实验中,与模型组比较,大孔树脂90%乙醇洗脱部位组小鼠的扭体次数显著减

          ABSTRACT   OBJECTIVE  To  study  the  pharmacological  substance  basis  of  Shaoyao  gancao  decoction  for  relieving  acute  and
          chronic  pain.  METHODS  The  antispasmodic  effect  of  Shaoyao  gancao  decoction,  ethyl  acetate  extract  of  Shaoyao  gancao
          decoction  and  its  effluent  part  of  macroporous  resin  and  90%  ethanol  elution  part  of  macroporous  resin (the  concentration  of  4
          drugs was 13.44 g/mL according to crude drug) was observed by in vitro small intestine tension test in rats. The acetic acid writhing
          test  was  conducted  in  mice  to  evaluate  the  analgesic  effects  of  macroporous  resin  efflux  site  and  macroporous  resin  90%  ethanol
          elution site (the dosage of 2.4 g/kg according to crude drug). The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-
          1β),  prostaglandin  E2 (PGE2 )  and  cyclooxygenase-2 (COX-2)  in  serum  of  mice  were  detected.  The  serum  prototype  and
          metabolites  of  mice  after  intragastric  administration  of  macroporous  resin  90%  ethanol  elution  site  were  identified  by  high
          performance  liquid  chromatogre-time-of-flight  mass  spectrometry.  RESULTS  In  vitro  experiment  showed  that  90%  ethanol  eluting
          part  of  macroporous  resin  represented  the  best  antispasmodic  effect,  and  the  inhibitory  rate  of  small  intestine  tension  was
          significantly  higher  than  macroporous  resin  efflux  site  of  Shaoyao  gancao  decoction (P<0.05)  without  statistical  significance,
          compared  with  Shaoyao  gancao  decoction (P>0.05).  In  the  acetic  acid  writhing  experiment,  compared  with  model  group,  the
          writhing times of mice in the macroporous resin 90% ethanol elution part group were reduced significantly (P<0.05), the writhing
          latency  was  prolonged  significantly (P<0.05),  and  the  levels  of  COX-2,  IL-1β,  PGE2  and  TNF- α  in  serum  were  decreased
          significantly (P<0.05).  Ten  kinds  of  protoproducts  including  paeoniflorin  and  glycyrrhizic  acid  were  identified  from  serum  of
          mice,  and  twenty-two  kinds  of  metabolites  including  hydroxylated  glycyrrhizin  and  glucosylated  liquiritin  were  identified.
          CONCLUSIONS  The  effective  part  of  Shaoyao  gancao  decoction  for  relieving  acute  and  chronic  pain  is  90%  ethanol  elution
                                                             part  prepared  by  macroporous  resin  from  the  ethyl  acetate
