摘要

目的：从代谢组学角度探究金芪降糖片改善2型糖尿病大鼠脂代谢紊乱的作用机制。方法：雄性Wistar大鼠45只，采用高脂饲料喂养联合3次小剂量腹腔注射链脲霉素（STZ，35 mg·kg-1）复制2型糖尿病模型，造模成功后随机分为正常组、模型组、金芪降糖片组。金芪降糖片组连续给药4周，给药结束后腹主动脉取血，利用半自动生化分析仪检测血脂水平，苏木精-伊红（HE）染色观察肝脏病理变化；采用UPLC-Q-TOF-MS对不同组别的血液样本进行检测，运用主成分分析（PCA）和偏最小二乘法-判别分析（PLS-DA）筛选正常组、模型组和金芪降糖片组之间的差异代谢物，结合质谱信息和公共数据库检索对差异代谢物进行鉴定并进行京都基因与基因组百科全书（KEGG）代谢通路分析。结果：与正常组比较，模型组大鼠血脂水平明显升高，金芪降糖片组血脂较模型组明显下降，模型组肝脏出现明显的脂肪粒细胞，金芪降糖片组肝细胞脂肪粒明显减少。模型组和正常组大鼠有12种内源性物质发生了显著性变化，经金芪降糖片干预后花生四烯酸，左旋肉碱，溶血磷脂酰胆碱（LysoPC）（17：0），LysoPC （P-18：0），LysoPC[22：4（7Z，10Z，13Z，16Z）]，硬脂酰肉碱这6种代谢物水平出现了不同程度的回调，得到1条关键代谢通路——花生四烯酸代谢通路。结论：金芪降糖片对2型糖尿病脂代谢紊乱大鼠体内的差异代谢物有一定的回调作用，其作用机制主要与花生四烯酸代谢通路有关。

Abstract

Objective: To explore the mechanism of Jinqi Jiangtang tablets on improving lipid metabolism disorder in type 2 diabetic rats from the perspective of metabonomics.Method: Type 2 diabetes mellitus model was established in 45 male Wistar rats fed with high fat diet and 3 times of intraperitoneal injection of streptozotocin(STZ

35 mg·kg-1).After successful modeling

the rats were randomly divided into normal group

model group and Jinqi Jiangtang tablets group.Jinqi Jiangtang tablets group was administered continuously for 4 weeks.At the end of administration

the blood was taken from the abdominal aorta and the blood lipid level was detected by a semi automatic biochemical analyzer

the pathological changes of the liver were observed by hematoxylin-eosin(HE) staining;the blood samples in different groups were detected by UPLC-Q-TOF-MS.Principal component analysis (PCA) and partial least squares-discriminant analysis(PLS-DA) were used to screen the differential metabolites among the normal group

model group and Jinqi Jiangtang tablets group

these differential metabolites were identified by mass spectrometry information and public database retrieval

and their metabolic pathways of the Kyoto encyclopedia of genes and genomes(KEGG) were analyzed.Result: Compared with the normal group

the level of blood lipid in the model group was significantly increased

the serum lipids in Jinqi Jiangtang tablets group were significantly lower than those in the model group.In the model group

obvious fatty granulocytes appeared in the liver

the hepatocyte fat granulocytes were significantly decreased in the administration group.There were 12 kinds of endogenous substances with significant changes in type 2 diabetes mellitus model group and the normal group.After intervention with Jinqi Jiangtang tablets

the levels of arachidonic acid

L-carnitine

lyso-phosphatidylcholine(LysoPC)(17:0)

LysoPC(P-18:0)

LysoPC[22:4(7Z

10Z

13Z

16Z)] and stearyl carnitine showed a different degree of callback.A key metabolic pathway

arachidonic acid pathway

was obtained by further analysis of the metabolic pathway.Conclusion: Jinqi Jiangtang tablets has a certain callback effect on the differential metabolites of lipid metabolism in rats with type 2 diabetes mellitus

and its mechanism is mainly related to arachidonic acid metabolic pathway.
