目的
2
采用网络药理学探讨芍药汤治疗溃疡性结肠炎(UC)的作用机制,并进行实验验证。
方法
2
基于网络药理学预测芍药汤的核心成分、靶基因和主要通路;对其中UC相关成分、靶基因、通路进行筛选;利用葡聚糖硫酸钠(DSS)诱导UC小鼠模型,观察芍药汤对UC小鼠的作用,并进一步验证其机制。
结果
2
网络药理学提示,芍药汤筛选出有效成分为174个,对应的作用靶基因为159个,相关的作用通路集中于5-羟色胺(5-HT)降解及5-HT 3型受体介导的信号通路。动物实验结果表明,与模型组比较,芍药汤组的小鼠的体质量显著升高(
P
<
0.01),结肠长度显著增长(
P
<
0.01),疾病活动指数(DAI)评分降低(
P
<
0.01),且能有效改善UC模型小鼠的组织病理学表现,降低结肠及血清中5-HT水平(
P
<
0.05,
P
<
0.01),升高结肠中5-HT代谢相关的单胺氧化酶A(MAOA)、单胺氧化酶B(MAOB)、钠依赖性血清素转运体(SLC6A4)、5-HT受体3A(5-HTR3A)mRNA水平(
P
<
0.01)。
结论
2
芍药汤可能通过调控5-HT降解通路改善UC肠道局部的炎症反应。
Objective
2
To explore the mechanism of Shaoyaotang (SYT) in the treatment of ulcerative colitis (UC) based on network pharmacology and experimental verification.
Method
2
The core components, target genes, and main pathways of SYT were predicted based on network pharmacology, and UC-related components, target genes, and pathways were screened. Dextran sodium sulfate (DSS) was used to induce the UC model in mice, and the effect of SYT on UC mice was observed, followed by mechanism verification.
Result
2
Network pharmacology indicated that 174 active components and corresponding 159 target genes of SYT were screened, and the related pathways were those mediated by 5-hydroxytryptamine (5-HT) degredation and 5-HT receptor 3. The results of animal experiments showed that compared with the model group, the SYT group showed increased body weight and colon length(
P
<
0.01), reduced disease activity index (DAI) score (
P
<
0.01), improved histopathological manifestations, reduced concentrations of 5-HT in the colonic tissues and serum (
P
<
0.05,
P
<
0.01), and increased mRNA expression of monoamine oxidase A (MAOA), monoamine oxidase B (MAOB), sodium-dependent serotonin transporter (SLC6A4), and 5-HT receptor 3A (5-HTR3A) related to 5-HT metabolism in the colon (
P
<
0.01).
Conclusion
2
SYT can alleviate the local inflammatory response of the intestinal tract in UC by regulating 5-HT degredation pathways.
