摘 要 目的 观察加味芍药甘草汤对慢传输型便秘(STC)大鼠肠道传输功能、肠道菌群及共代谢产物γ氨基丁酸(GABA)和5-
羟色胺(5-HT)含量的影响。方法 将SD大鼠随机分为空白组(10只)和造模组(30只),雌雄各半。造模组大鼠以复方地芬诺酯灌胃
法构建STC模型。将造模成功的大鼠随机分为模型组、加味芍药甘草汤组[56 g/(kg·d),以生药量计]、阳性对照药组[乳果糖2.09
g/(kg·d)],每组10只。各药物组大鼠灌胃相应药液,空白组和模型组大鼠灌胃等体积生理盐水,每天1次,连续14 d。实验期间,
观察各组大鼠的一般情况;末次给药后,称定其体重并对粪便性状进行Bristol评分,检测粪便含水率、肠道推进率和肠内容物中
GABA、5-HT 含量,考察肠内容物中肠道菌群的多样性,并分析 GABA、5-HT 含量与菌群相对丰度的关联性。结果 与模型组比
较,加味芍药甘草汤组大鼠体形瘦小、皮毛稀疏粗糙、行动迟缓等一般情况均有所改善,体重、Bristol评分、粪便含水率、肠道推进
率、5-HT含量、Chao1和Shannon指数均显著升高,GABA含量、Simpson指数均显著降低(P<0.05)。该组大鼠的肠道菌群可与空
白组归为一类,但与模型组相距较远;该组脱硫杆菌门、厚壁菌门、拟杆菌门的相对丰度虽有回调,但与模型组比较差异均无统计
学意义(P>0.05);脱硫杆菌门是组间差异因素(P<0.05)。GABA含量与拟杆菌门、蓝菌门、髌骨菌门、放线菌门的相对丰度呈负
相关(P<0.01或P<0.05),5-HT含量与弯曲杆菌门的相对丰度呈正相关(P<0.05)。结论 加味芍药甘草汤可改善STC模型大鼠
粪便性状和肠道动力,上述作用可能与改善肠道菌群,进而影响肠内容物中GABA、5-HT含量有关;此外,GABA、5-HT含量可能
与拟杆菌门、弯曲杆菌门等特定菌门的相对丰度显著相关。

ABSTRACT OBJECTIVE To observe the effects of Modified shaoyao gancao decoction on intestinal transit function, intestinal
flora and the contents of metabolites [γ aminobutyric acid (GABA) and 5-hydroxytryptamine (5-HT)] in slow transit constipation
(STC) rats. METHODS SD rats were randomly divided into blank group (10 rats) and modeling group (30 rats), with half male
and half female. The STC model was established by intragastric administration of Compound diphenoxylate tablets in the modeling
group. The successfully modeled rats were randomly divided into model group, Modified shaoyao gancao decoction group [56 g/(kg·d),
calculated by crude drug] and positive control group [lactulose 2.09 g/(kg·d)], with 10 rats in each group. Each administration
group was given relevant medicine intragastrically, the blank group and model group received an equivalent volume of normal
saline, once a day, for 14 consecutive days. During the experiment, the general situation of rats was observed in each group. After
the last medication, the body weight was measured, and the Bristol score was used to evaluate the fecal characteristics. The fecal
moisture content, intestinal propulsion rate, and the contents of GABA and 5-HT in intestinal content were detected; the diversity
of intestinal flora in intestinal contents was investigated, and
