方法
2
雄性Balb/c小鼠按体质量随机分为正常组、模型组、黄芩汤高(20 g·kg

α
(TNF-
α
)含量,实时荧光定量聚合酶链式反应(Real-time PCR)及蛋白免疫印迹法(Western blot)检测结肠组织中紧密连接蛋白1(Claudin1)、黏蛋白1(MUC1)、咬合蛋白(Occludin)、闭锁小带蛋白-1(ZO-1) mRNA和蛋白的表达,提取小鼠粪便DNA进行高通量测序分析。
结果
2
与正常组比较,模型组小鼠血清IL-4、IL-6、TNF-
α
含量明显升高(
P
<
0.05,
P
<
0.01),IL-10明显降低(
P
<
0.05);与模型组比较,黄芩汤给药组IL-4、IL-6、TNF-
α
含量下降(
P
<
0.05,
P
<
0.01),IL-10含量显著上升(
P
<
0.01),Claudin1、MUC1、Occludin、ZO-1 mRNA和蛋白表达明显上升(
P
<
0.05,
P
<
0.01)。菌群干扰后,小鼠肠道菌物种多样性及丰度降低,变形菌门(Proteobacteria)增多(
P
<
0.01),厚壁菌门(Firmicutes)、拟杆菌门(Bacteroidetes)减少(
P
<
0.01);DSS诱发UC后,拟杆菌门和柔壁菌门(Tenericutes)明显减少(
P
<
0.05);黄芩汤高、中、低3个剂量组中拟杆菌门、柔壁菌门明显增多(
P
<
0.05,
P
<
0.01),厚壁菌门减少(
P
<
0.05),乳酸菌属(
Lactobacillus
)、毛螺菌属(
Lachnospiraceae NK4A136 group
)、大肠埃希菌志贺属(
Escherichia-Shigella
)、螺杆菌(
Helicobacter
)的丰度与黄芩汤剂量呈正比。
结论
2
黄芩汤可以抑制UC小鼠的炎症反应,回调失衡的肠道菌群,修复损伤的肠黏膜屏障。
Objective
2
To evaluate the pharmacodynamic effect of Huangqintang (HQT) on ulcerative colitis (UC) model mice and investigate its protective effect against UC by regulating intestinal flora.
Method
2
Male Balb/c mice were randomly divided into control group,model group, high-, medium-, and low-dose HQT groups (20, 10, 5 g·kg
-1
), flora interference group, flora interference model group, and flora interference-drug treatment group (HQT, 20 g·kg
-1
). The flora interference model was constructed through intragastric administration of antibiotics (200 mg·kg
-1
bacitracin and 200 mg·kg
-1
vancomycin) for 8 d, and the UC model was constructed by allowing mice with free access to 3% dextran sulfate sodium (DSS) solution for 7 d. HQT was administered for 7 d. After the experiments, the mice were sacrificed, and blood, colon, and feces were collected. Hematoxylin-eosin (HE) staining was performed to observe the colonic lesions. The serum levels of interleukin (IL)-4, IL-6, IL-10, and tumor necrosis factor (TNF)-
α
were detected by enzyme-linked immunosorbent assay (ELISA). The mRNA and protein expression of Claudin1, MUC1, Occludin, and zonula occludens-1(ZO-1) in colon tissues was detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. The fecal DNA of mice was extracted and analyzed by high-throughput sequencing.
Result
2
Compared with the normal group, the model group showed increased serum content of IL-4, IL-6, and TNF-
α
(
P
<
0.05,
P
<
0.01) and decreased IL-10 (
P
<
0.05). Compared with the model group, the HQT groups displayed decreased serum levels of IL-4, IL-6, and TNF-
α
(
P
<
0.05,
P
<
0.01), increased IL-10 content (
P
<
0.01), increased mRNA and protein expression levels of Claudin1, MUC1, Occludin, and ZO-1 (
P
<
0.05,
P
<
0.01). After flora interference, the diversity and abundance of intestinal bacteria decreased. To be specific, Proteobacteria increased (
P
<
0.01), and Firmicutes and Bacteroidetes decreased (
P
<
0.01). After UC induction by DSS, Bacteroidetes and Tenericutes decreased (
P
<
0.05). The high-, medium-, and low-dose HQT groups showed increased Bacteroidetes and Tenericutes (
P
<
0.05,
P
<
0.01) and decreased Firmicutes (
P
<
0.05). Additionally, the abundance of
Lactobacillus
,
Lachnospiraceae NK4A136 group
,
Escherichia-Shigella
, and
Helicobacter
is was positively proportional to the dose of HQT.
Conclusion
2
HQT can inhibit the inflammatory response of UC mice, restore the imbalance of intestinal flora, and repair the damaged intestinal mucosal barrier.
