摘要: 目的  探索糖尿病与肠道菌群失调以及炎症因子和C反应蛋白的相关性。方法  将肠道菌群作为暴露因素,糖尿病、炎症因子和C反应蛋白作为结局因素,以单核苷酸多态性(single nucleotide polymorphisms, SNPs)作为工具变量,采用孟德尔随机化分析方法探讨肠道菌群与糖尿病、炎症因子和C反应蛋白的关系。结果  粪球菌、戴阿利斯特杆菌、毛螺菌和吉氏拟杆菌等在糖尿病人群中丰度相对较低,而嗜胆菌和罗姆布茨菌在糖尿病人群中丰度相对较高。戴阿利斯特杆菌与白介素-17(interleukin-17,IL-17)相关(β=0.797,P=0.036)。C反应蛋白与粪球菌(β=-0.036,P=0.027)、吉氏拟杆菌(β=-0.216,P=0.015)和戴阿利斯特杆菌 (β=-0.028,P=0.030)均呈负相关。对于粪球菌和吉氏拟杆菌与糖尿病的关系,C反应蛋白存在中介效应。结论  本研究结果提示肠道菌群、C反应蛋白和糖尿病存在潜在的相互作用。

Abstract: Objective  To explore the relationship between intestinal flora and diabetes mellitus, inflammatory factors and C-reactive protein (CRP).Methods  In this study, the intestinal flora was taken as exposure factors while diabetes, inflammatory factors and CRP were taken as outcome factors, and single  nucleotide polymorphisms(SNPs) were used as instrument variables. Mendelian randomization method was used.  Results  Coprococcus1, Dialister, Lachnospiraceae and Parabacteroides were less abundant in the diabetes population whereas Bilophila and Romboutsia were more abundant in the diabetes population. Dialister is positively correlated with interleukin-17(IL-17) (β=0.797, P=0.036). CRP is negatively correlated with Coprococcus1 (β=-0.036, P=0.027), Parabacteroides (β=-0.216, P=0.015), and Dialister (β=-0.028, P=0.030). CRP showed the mediation effect in the relationship between two bacteria (Coprococcus1 and Parabacteroides) and diabetes.Conclusion  Our study suggests the potential interactions between intestinal flora, CRP and diabetes.
