Objective:The purpose of this study is to investigate the anti-diabetic effects of linarin,a flavonoid extracted from Chrysanthemi Indici Flos(CIF),and its potential mechanisms.Methods:The effects of linarin on cell viability and glucose consumption in HepG2 cells were measured.Meanwhile,monosodium glutamate(MSG)mouse model was constructed to monitor the changes of insulin tolerance,glucose tolerance,triglyceride and cholesterol.The protein expression levels of p-AMPK,p-ACC,PEPCK and p-GS were detected by Western blot.Results:Linarin could increase the relative glucose consumption of HepG2 cells,improve insulin toler-ance and glucose tolerance,and decrease the levels of triglyceride and cholesterol of MSG mice.Simultaneously,the expression levels of p-AMPK and p-ACC in HepG2 cells and the liver tissue of MSG mice were increased,while the expression levels of PEPCK and p-GS were decreased after treatment with linarin.Conclusion:Insulin resistance could be ameliorated by linarin in type 2 diabetes,and its mechanism may be related to AMPK signaling pathway.

膀胱作为泌尿系统的主要器官之一,具有储尿和排尿两大重要功能.调控这两大功能的神经传导通路非常复杂,涉及到大脑、脊髓和外周神经系统等多个层次,并由多种神经递质共同介导.在过去的20年里,电生理学技术和功能磁共振成像技术逐渐成为神经功能学领域内研究人类病理或生理状态的有力手段,利用这两项技术来记录和分析膀胱储尿排尿行为的大脑调控机制是可行的,两者可以帮助我们更好地理解控尿相关的神经通路和大脑区域的活动与特定功能之间的关系.本文就电生理学技术和功能磁共振成像技术方面,对膀胱及原位新膀胱的充盈和储尿控尿机制的神经
