目的
2
探讨黄连平胃散治疗溃疡性结肠炎(UC)小鼠的作用机制。
方法
2
高效液相色谱串联质谱(UPLC-MS/MS)检测药物主要成分,TCMSP数据库和PubChem数据库检索药物成分作用靶点,GeneCards数据库检索UC疾病靶点,筛选成分-疾病共同靶点并利用生物信息学方法分析其功能。利用葡聚糖硫酸钠(DSS)诱导昆明鼠构建UC模型,代谢组学方法分析黄连平胃散对代谢产物的影响,苏木精-伊红(HE)染色和阿尔辛蓝-过碘酸希夫(AB-PAS)染色观察结肠组织炎症及黏液变化,免疫组织化学法检测结肠组织中闭锁小带蛋白-1(ZO-1)表达,酶联免疫吸附分析(ELISA)法检测血清肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)和活性氧(ROS)水平,Western blot法检测结肠组织中磷酸化蛋白53(p53)和半胱氨酸-天冬氨酸蛋白酶3(CASP3)蛋白水平,分子对接验证主要成分与p53和CASP3结合亲和力和结合模式。
结果
2
黄连平胃散成分主要由黄酮类、糖及糖苷类、苯丙素类、生物碱及萜类组成,该方剂可调节小鼠血清中单磷酸腺苷、二磷酸尿苷葡萄糖及吲哚类化合物的代谢,显著降低血清TNF-α、IL-6、ROS水平,增加上皮紧密连接蛋白ZO-1表达和黏液分泌,减轻肠组织炎症细胞浸润,并抑制结肠组织p53和CASP3蛋白表达;分子对接显示,去氢紫堇茎碱和小檗碱均与p53和CASP3靶点具有较高的结合力。
结论
2
黄连平胃散可通过抑制p53信号通路减轻肠道炎症和改善肠道功能。
Objective
2
To investigate the therapeutic mechanism of Huanglian Pingwei Powder in treating ulcerative colitis (UC) model.
Methods
2
Ultra-Performance Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (UPLC-MS/MS) was used to detect the main components of the drug. The TCMSP and PubChem databases were used to identify the targets of the drug's components. The UC model was established in mice using dextran sulfate sodium (DSS). Metabolomics analysis was conducted to assess the effects of Huanglian Pingwei Powder on metabolites. Hematoxylin and Eosin (HE) staining and Alcian Blue-Periodic Acid-Schiff (AB-PAS) staining were used to observe changes in inflammation and mucus in colon tissue. Immunohistochemistry was performed to detect the expression of Zonula Occludens-1(ZO-1), and Enzyme-Linked Immunosorbent Assay (ELISA) was used to measure serum levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and reactive oxygen species (ROS). Western blot was used to assess the levels of phosphorylated protein 53 (p53) and cysteine aspartate-specific protease 3 (CASP3) proteins in colon tissue. Molecular docking was used to validate the binding affinity and interaction modes of key compounds with p53 and CASP3.
Results
2
Huanglian Pingwei Powder is primarily composed of flavonoids, saccharides and glycosides, phenylpropanoids, alkaloids, and terpenoids. Treatment with this formula regulated serum metabolites such as adenosine monophosphate, guanosine diphosphate-glucose, and indole compounds, significantly reducing serum TNF-α, IL-6, and ROS levels. It also increased expression of ZO-1 and mucin secretion, reduced inflammatory cell infiltration in intestinal tissue, and inhibited p53 and CASP3 protein expression in colon tissue. Both dehydrocorydaline and coptisine exhibited strong binding affinity for p53 and CASP3.
Conclusion
2
Huanglian Pingwei Powder alleviates intestinal inflammation and improves gut function by inhibiting the p53 signaling pathway.
