Berberis amurensis(Berberidaceae)is a traditional Chinese medicine,which is often used to treat hypertension,in-flammation,dysentery and enteritis.It contains alkaloids,mainly including berberine,berbamine,magnoflorine,jatrorrhizine and pal-matine.Berberis amurensis extracts(BAEs)is often orally taken.Oral herbs might be metabolized by intestinal bacteria in the small intestine.However,the interaction between the herb and the gut microbiota is still unknown.In the current study,UPLC/Q-TOF-MS/MS combined with Metabolitepilot and Peakview software was used to identify the metabolites of BAEs in anti-biotic cocktail in-duced pseudo germ-free rats and normal rats.As a result,a total of 46 metabolites in normal rats were detected and its main metabolic pathways include demethylation,dehydrogenation,methylation,hydroxylation,sulfation and glucuronidation.Only 29 metabolites ex-isted in pseudo germ-free rats.Dehydrogenated metabolites(M29,M30,M34 and M36),methylated metabolites(M33,M41 and M46)and other metabolites were not detected in pseudo germ-free rats.The result implied that the intestinal bacteria have an influence on the metabolism of BAEs.Furthermore,this investigation might contribute to the understanding of the metabolism of BAEs,and fur-ther promote its clinical application.

DKD是DM常见微血管并发症,由于长期高血糖及高胰岛素血症,机体处于血栓前状态,易伴发肾小球微血栓(GMT)形成.炎症信号通路和炎症因子参与GMT形成,引起微循环障碍,加速肾小球硬化,加重肾脏损伤.本文对DKD引起的GMT与炎症相关性研究进展进行综述.
动态血糖监测(CGM)技术迅速发展,已成为DM管理的重要方法.规范合理应用CGM系统可明显降低DM患者HbA1c水平,减少血糖波动及低血糖风险,提高血糖控制效果和生活质量,对改善DM患者预后意义重大.本文对CGM技术与临床研究进展进行综述.

一、Ins治疗现状及挑战rn中国DM患者负担沉重,约占全球DM患者的1/4[1].尽管DM防控工作取得一定进步,但我国仍有50. 6％的T2DM患者未能实现良好的血糖控制[2].DM作为一种进展性疾病[3],起始Ins治疗是疾病管理的必经阶段[4].基础胰岛素方案是国内外指南[5-6]共同推荐的Ins起始方案,且一旦起始基础胰岛素治疗,为实现良好的血糖控制,对Ins剂量的合理调整十分必要.
