Mechanism of Danggui Sini Decoction(当归四逆汤)for Atherosclerosis Obliterans Based on Network Pharmacology and Molecular Docking

Objective:Based on network pharmacology and molecular docking,we want to explore the pharmacological effects and mechanism of Danggui Sini Decoction in the treatment of lower extremity arteriosclerosis obliterans.Methods:Using TCMSP database to search the main active components of Danggui Sini Decoction(当归四逆汤,DSD)and their related targets,Cytoscape3.8.1 software was used to construct a"component-disease-target"interaction network.Meanwhile,DAVID database was used to enrich the key target genes with GO and KEGG functions.And we used Auto Dock Tools 1.5.6 for molecular docking.Results:A total of 45 candidate active molecules and 250 potential target proteins related to ASO were screened.Key genes such as TNF,IL6,VEGFA,MMP9,IL1B,CCL2,CXCL8,ICAM1,VCAM1,and IL10 are mainly through TNF signaling pathway,HIF-1 signaling pathway,cytokine-cytokine receptor interaction,Toll-like receptor signaling pathway,NF-kappa B signaling pathway,MAPK signaling pathway and other biological pathways exert their effects.The results of molecular docking showed that 5UUI-sesamin,5UUI-paeoniflorin,4XCT-sesamin,and 4XCT-sesamin have extremely strong binding ability.Conclusion:Danggui Sini Decoction(当归四逆汤,DSD)can synergistically exert pharmacological effects through multiple components,multiple targets,and multiple pathways.On the basis of regulating immunity and inhibiting smooth muscle proliferation,it can prevent the occurrence and development of ASO.

当归四逆汤对心肌缺血大鼠心肌SOD及MDA表达的影响

目的:观察当归四逆汤对心肌缺血大鼠心肌SOD及MDA表达的影响。方法:采用雄性Wistar大鼠腹腔注射垂体后叶素(Pit)(30U/kg)造成急性心肌缺血损伤模型;药物干预后,观察心尖部心肌组织病理学改变,并检测超氧化物歧化酶(SOD)和丙二醛(MDA)活性。结果:光镜下显示,空白对照组心肌纤维排列整齐,心肌细胞核位于心肌纤维的中央,胞浆着色均匀;模型组心肌纤维排列轻度紊乱,呈波浪状改变,部分心肌细胞核出现溶解;当归四逆汤高、低剂量组及阳性对照组心肌纤维排列较整齐,细胞结构未见明显病理改变。模型组SOD活性明显低于空白对照组(P<0.01),MDA含量明显高于空白对照组(P<0.01);当归四逆汤高剂量组、低剂量组及阳性对照组SOD活性均明显高于模型组(P<0.05或P<0.01),MDA含量均明显低于模型组,差异均有统计学意义(P<0.05或P<0.01);当归四逆汤低剂量组SOD活性及MDA含量均高于当归四逆汤高剂量组,但差异均无统计学意义(P>0.05)。结论:当归四逆汤能提高垂体后叶素所致急性心肌缺血大鼠SOD活性,减少MDA含量,增强机体清除氧自由基的能力,抑制脂质过氧化损伤的发生,保护心肌细胞。
