目的
2
使用16S rDNA测序技术分析利胆消石合剂对胆石症豚鼠肠道菌群的影响。
方法
2
用随机数字表法将豚鼠分为对照组(CG)10只,模型组(MG)、胆宁片(DN)组、中药低剂量(ZD)组、中药中剂量(ZZ)组、中药高剂量(ZG)组各15只。除CG组外,其他各组采用胆道插管、注射复发型胆总管结石患者胆道细菌培养液的方式制备胆道结石复发模型。造模结束后次日,DN组给予0.05 g/(100 g·d)胆宁片灌胃,ZD、ZZ、ZG组分别给予0.16、0.32、0.64 g/(100 g·d)利胆消石合剂颗粒灌胃,CG、MG给予等体积蒸馏水灌胃,均持续7 d。采用16S rDNA技术检测各组豚鼠肠道菌群的组成,分析肠道菌群的组成结构及丰度变化。
结果
2
造模方式显著改变了肠道菌群的组成结构,MG与其他各组的肠道菌群物种组成差异有统计学意义(
P
<
0.05);利胆消石合剂各干预组改变了造模导致的物种组成结构。并且在属水平6组间共有12种菌属在群落丰度上差异有统计学意义(
P
<
0.05)。
结论
2
利胆消石合剂可能通过调节肠道菌群的结构组成,影响“胆汁酸-肠道菌群”平衡及胆汁酸的“肠肝循环”,从而影响胆总管结石的复发。
Objective
2
To investigate the effects of
Lidan Xiaoshi Mixture
on the intestinal microbiota of guinea pigs with cholelithiasis using 16S rDNA sequencing technology.
Methods
2
Guinea pigs were randomly assigned by random number table method into six groups: control group (CG,
n
=10), model group (MG,
n
=15), Danning Tablets group (DN,
n
=15), low-dose
Lidan Xiaoshi Mixture
group (ZD,
n
=15), medium-dose
Lidan Xiaoshi Mixture
group (ZZ,
n
=15), and high-dose
Lidan Xiaoshi Mixture
group (ZG,
n
=15). Except for CG, the other groups were subjected to biliary tract intubation and injection of biliary bacterial culture solution from patients with recurrent common bile duct stones to establish a recurrent biliary calculi model. On the day following model establishment, the DN group received
Danning Tablets
at 0.05 g/(100 g·d) by gavage, while the ZD, ZZ, and ZG groups received
Lidan Xiaoshi Mixture
at 0.16, 0.32, and 0.64 g/(100 g·d), respectively. CG and MG received equal volumes of distilled water. All treatments were administered for 7 days. The intestinal microbiota composition of each group was analyzed using 16S rDNA sequencing, and changes in microbial composition and abundance were evaluated.
Results
2
The modeling procedure significantly altered the intestinal microbiota composition, with the MG group showing statistically significant differences in species composition compared with other groups (
P
<
0.05). Intervention with
Lidan Xiaoshi Mixture
restored the species composition disrupted by modeling. At the genus level, 12 bacterial genera showed significant differences in community abundance among the six groups (
P
<
0.05).
Conclusion
2
Lidan Xiaoshi Mixture
may modulate the structural composition of the intestinal microbiota, influencing the balance of the "bile acid-intestinal microbiota" axis and the enterohepatic circulation of bile acids, thereby affecting the recurrence of common bile duct stones.
