目的 探究"雅解沙把"对酒精诱导肝损伤小鼠的药效作用,通过16S rDNA技术研究"雅解沙把"对肠道菌群的调节作用机制。方法 取健康雄性KM小鼠随机分为空白组、模型组、"雅解沙把"低剂量、中剂量、高剂量(0。39、1。17、3。51 g生药·kg-1)组和联苯双酯(2。93 mg·kg-1)组,每组8只。"雅解沙把"预给药1周后,一次性灌服56%酒精建立小鼠急性酒精性肝损伤模型,检测小鼠血清中AST和ALT的含量,并通过HE染色观察肝脏组织病理形态学的变化;其次,在无菌操作下提取各组大鼠粪便DNA,进行16S rDNA测序并通过Alpha多样性及门和属水平上物种组成进行差异分析。结果 "雅解沙把"对肝功生化指标(ALT、AST)均有明显的改善作用,HE染色结果显示,肝损伤程度明显减轻;同时,16S rDNA测序研究表明"雅解沙把"具有增加急性酒精性小鼠肠道菌群多样性的作用;在门水平上,"雅解沙把"可显著降低变形菌门丰度,增高拟杆菌门丰度;在属水平上,"雅解沙把"显著上调拟杆菌属、拟普雷沃氏菌属丰度,下调普氏菌属和幽门螺杆菌属丰度,使肠道菌群处于动态平衡状态。结论 "雅解沙把"可能通过调节肠道菌群及其代谢产物来发挥抗急性酒精性肝损伤的作用。
To Study the Mechanism of"Yajieshaba"Against Acute Alcoholic Liver Injury in Mice Based on 16S rDNA Technology
Objective To investigate the pharmacological effects of"Yajieshaba"on mice with alcohol-induced liver injury and to investigate the mechanism of the impact of"Yajieshaba"on the regulation of intestinal flora by 16S rDNA technology.Methods Healthy male KM mice were randomly divided into control,model,"Yajieshaba"low,medium,and high dose(0.39,1.17 and 3.51 g·kg-1)groups and Bifendatatum(2.93 mg·kg-1)groups,with eight mice in each group.After one week of pre-administration of"Yajieshaba",a mouse model of acute alcoholic liver injury was established by a single instillation of 56%alcohol,and the levels of AST and ALT in the serum of mice were measured,and the morphological changes of liver histology were observed by HE staining;secondly,faecal DNA was extracted from each group under aseptic operation,and 16S rDNA sequencing and differential analysis by alpha diversity and species composition at the phylum and genus levels were performed.Results The results showed that the biochemical indexes of liver function(ALT and AST)were significantly improved by"Yajieshaba",and the degree of liver damage was significantly reduced by HE staining.At the phylum level,it significantly decreased the abundance of Aspergillus and increased the quantity of Bacteroides;at the genus level,it significantly up-regulated the plenty of Bacteroides and Prevotella and downregulated a lot of Prevotella and Helicobacter.At the genus level,"Yajieshaba"significantly up-regulated the abundance of Bacillus spp.and Prevotella spp.and down-regulated the abundance of Prevotella spp.and Helicobacter spp.Conclusion"Yajieshaba"may play an anti-acute alcoholic liver injury effect by regulating the intestinal flora and metabolites.
