          摘   要  目的  探讨肉苁蓉多糖(简称CDPS)对便秘型肠易激综合征(IBS-C)大鼠的影响。方法  将SD大鼠分为对照组(20只)和
          造模组。造模组大鼠灌胃0~4 ℃生理盐水2 mL(每天1次,连续14 d)诱导IBS-C模型。将造模成功的大鼠分为模型组、阳性对照
          组(枸橼酸莫沙必利,1.35 mg/kg)和CDPS低、高剂量组(50、100 mg/kg),每组20只。各药物组大鼠灌胃相应药液,对照组和模型
          组大鼠灌胃等体积水,每次1次,持续28 d。检测各组大鼠的粪便含水量、血清5-羟色胺(5-HT)含量、炭末推进率,观察其结肠组
          织病理形态并检测结肠组织中神经生长因子(NGF)、原肌球蛋白受体激酶A(TrkA)mRNA及蛋白的表达。结果  与对照组比较,
          模型组大鼠的粪便含水量和炭末推进率均显著降低(P<0.05),结肠组织黏膜肌层断裂,炎症细胞浸润和细胞水肿明显,血清
          5-HT含量和结肠组织中NGF、TrkA mRNA及蛋白的相对表达量均显著升高(P<0.05)。与模型组比较,各药物组大鼠的粪便含水
          量和炭末推进率均显著升高(P<0.05),结肠组织病理改变明显减轻,血清5-HT含量和结肠组织中NGF、TrkA mRNA及蛋白的相
          对表达量均显著降低(P<0.05),其中,阳性对照组和CDPS高剂量组的上述指标普遍接近于对照组(P>0.05)。结论  CDPS可缓
          解IBS-C大鼠的症状,该作用可能与NGF/TrkA信号通路被抑制有关。

          ABSTRACT    OBJECTIVE  To  investigate  the  effects  of  Cistanches  Herba  polysaccharides (abbreviated  as  CDPS)  on  rats  with
          constipation-predominant  irritable  bowel  syndrome (IBS-C).  METHODS  SD  rats  were  divided  into  control  group (20  rats)  and
          modeling  group. The  modeling  group  was  given  2  mL  of  normal  saline  at  0-4  ℃  intragastrically (once  a  day,  for  14  consecutive
          days)  to  induce  IBS-C  model.  After  modeling,  model  rats  were  grouped  into  model  group,  positive  control  group (mosapride
          citrate,  1.35  mg/kg),  CDPS  low-dose  group (50  mg/kg)  and  CDPS  high-dose  group (100  mg/kg),  with  20  rats  in  each  group.
          Administration  groups  were  given  corresponding  drug  solution  intragastrically,  and  control  group  and  model  group  were  given  a
          constant volume of water intragastrically, once a day, for 28 consecutive days. The fecal water content, serum content of
          5-hydroxytryptamine (5-HT),  and  charcoal  powder  propulsion  rate  of  rats  were  determined  in  each  group;the  pathological
          morphology  of  colon  tissue  was  observed,  and  mRNA  and  protein  expressions  of  nerve  growth  factor (NGF)  and  tropomyosin
          receptor  kinase  A (TrkA)  in  colon  tissue  were  detected.  RESULTS  Compared  with  control  group,  the  fecal  water  content  and
          carbon powder propulsion rate in the model group were decreased significantly (P<0.05); the rupture of mucosal muscle layer in
          colon  tissue,  significant  infiltration  of  inflammatory  cells  and  cellular  edema  were  observed;  the  content  of  5-HT  in  serum,  and
          relative mRNA and protein expressions of NGF and TrkA were increased significantly (P<0.05). Compared with model group, the
          fecal water content and carbon powder propulsion rate of rats were increased significantly in administration groups (P<0.05), and
                                                              pathological  changes  of  colon  tissue  were  relieved  significantly,
