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,
