摘要

摘要: 目的探究恒古骨伤愈合剂联合广谱抗生素暴露对db/db小鼠胰岛素抵抗和肠道菌群影响。方法以野生型小鼠作对照，db/db小鼠随机分为4组：模型组、抗生素组、恒古骨伤愈合剂组、复合干预组；给药11周后，检测体重、空腹血糖、血清胰岛素，计算胰岛素抵抗指数，16S rDNA分析动物肠内容物菌群。结果与对照组比较，db/db小鼠体重、空腹血糖、胰岛素抵抗指数升高（P < 0.05）。相对于db/db小鼠，抗生素（ABS）组、恒古骨伤愈合剂（OK）组和复合干预组（AO）血糖和岛素抵抗指数（HOMA-IR）降低（ P < 0.05）；ABS组肠道菌群的shannon、simpson和 pielou_e指数下降（ P < 0.05）；而OK组升高（ P < 0.05）；AO组仅shannon和 pielou_e升高（ P < 0.05）。在门水平上，OK组厚壁菌门（ P < 0.05）、ABX（ P < 0.01）和AO组（ P < 0.01）变形菌门的丰度升高，OK组（ P < 0.05）、AO组（ P < 0.01）和ABX（ P < 0.01）的拟杆菌门相对丰度降低；在科水平，OK组毛螺菌科（ P < 0.05）、ABX和AO组肠杆菌科、萨特菌科及AO组坦纳菌科的丰度均升高（ P < 0.01），而OK组Muribaculaceae丰度降低（ P < 0.05）。LEFse分析显示，ABX组的优势菌均为变形菌门。OK组毛螺菌科NK4A136组和乳杆菌属，脱硫杆菌科和普雷沃氏菌科富集。AO组古氏副拟杆菌，阿克曼菌属和 γ- 变形菌纲摩根菌科及 α- 变形菌纲富集。结论广谱抗生素、恒古骨伤愈合剂单独或联合使用均有降低db/db小鼠血糖和胰岛素抵抗的作用，恒古骨伤愈合剂可改善抗生素对db/db肠道微生态损害。

Abstract: Objective To investigate the effects of Osteoking combined with antibiotic cocktail on insulin resistance and gut microbiota in db/db mice. Methods The wild mice were used as the control group, while db/db mice were randomly divided into the model group, Osteoking group （OK）, antibiotic group （ABX）, and Osteoking combined with antibiotic cocktail group （OA）. After the intragastric administration for 11 weeks, the following indices were investigated: body weight, fasting blood-glucose （FBG）, serum insulin and the changes of intestinal microflora by 16S rDNA sequencing technology in mice. Results Compared with the model group, levels of FBG and HOMA- IR were significantly decreased in OK, ABX, AO groups （P < 0.05）. And the shannon、simpson and pielou_e index of gut microbiota were significantly decreased in ABX group （ P < 0.05）, while they were increased in OK group （ P < 0.05）. The shannon and pielou_e index were increased in AO group （ P < 0.05）. At the phylum level, the relative abundance （RA） of Firmicutes （ P < 0.05） in OK group, RA of Proteobacteria in ABX （ P < 0.01）and AO groups （ P < 0.01） were significantly increased; while RA of Bacteroidota was significantly decreased in OK （ P < 0.05）, ABX （ P < 0.01）, AO （ P < 0.01）groups. At the family level, RA of Lachnospiraceae （ P < 0.05） in OK group, Enterobacteriaceae, Sutterellaceae in ABX and AO groups （ P <0.01）and Tannerellaceae in AO groups （ P < 0.01） were significantly increased; while RA of Muribaculaceae in OK group was significantly decreased （ P < 0.05）. The following gut microbiota were riched: Proteobacteria in ABX group, Lachnospiraceae NK4A136 group, Lactobacillus, Desulfobacteraceae and Prevotellaceae in OK group, Parabacteroides gordonii, Akkermansia, Morganellaceae and Alphaproteobacteria in AO group. Conclusion Osteoking, antibiotic cocktail alone or in combination have the effects of improving the insulin resistance in db/db mice. And Osteoking can improve the intestinal microflora imbalance induced by antibiotic cocktail.
