Abstract:
Objective To investigate the effects of Zuogui Jiangtang Tongmai Prescription on short-chain fatty acids(SCFAs)and G protein-coupled receptor 109A(GPR109A)in diabetic atherosclerotic mice;To explore its mechanism of improving diabetic atherosclerosis.Methods ApoE-/-mice were fed with high sugar and high fat diet and intraperitoneal injection of streptozotocin to establish atherosclerosis model of diabetes.After modeling,the mice were randomly divided into the model group,Western medicine group(metformin hydrochloride+atorvastatin),and Zuogui Jiangtang Tongmai Prescription low-,medium-and high-dosage groups(19,38,76 g/kg);and the other C57BL/6J mice were set as the control group,with 6 mice in each group.Each group was given solution for gavage,once a day for 4 weeks.Blood glucose of the mice were detected,HE staining was used to observe the morphology of the aorta,TG,TC,LDL-C and HDL-C contents were detected by fully automated biochemistry analyzers,ELISA was used to detect the contents of serum HbA1c,fasting insulin(FINS),interleukin(IL)-1β,IL-6 and tumor necrosis factor(TNF)-α,gas chromatography was used to detect the content of intestinal SCFAs,and RT qPCR and Western blot were used to detect the mRNA and protein expressions of GPR109A in ileal tissue and nuclear factor(NF)-κB p65 in aortic tissue,respectively.Results Compared with the control group,obvious plaques and inflammatory cells infiltration were seen in the aorta of the model group,the blood glucose and serum HbA1c,TG,TC,LDL-C,IL-1β,IL-6 and TNF-α contents increased(P<0.01),FINS and HDL-C content decreased(P<0.01),intestinal acetate,propionate,butyric acid,isobutyric acid and isovaleric acid contents decreased(P<0.01),GPR109A mRNA and protein expression in ileal tissue decreased,NF-κB p65 mRNA and protein expression in aortic tissue increased(P<0.01).Compared with the model group,the aortic plaque area and inflammatory cells infiltration were significantly improved in each drug intervention group,the blood glucose and serum HbA1c,TG,TC,LDL-C,IL-1β,IL-6 and TNF-α contents decreased(P<0.05,P<0.01);the FINS and HDL-C content increased(P<0.05,P<0.01),intestinal acetic,propionic,butyric acid,isobutyric acid and isovaleric acid contents increased(P<0.05,P<0.01),GPR109A mRNA and protein expression in ileal tissue increased and NF-κB p65 mRNA and protein expression in ileal tissue decreased decreased(P<0.05,P<0.01).Conclusion Zuogui Jiangtang Tongmai Prescription can improve glucolipid metabolism and inflammatory response in diabetic atherosclerotic mice,which may be related to regulating SCFAs/GPR109A pathway.
