RESUMO

@#To investigate the effect of ethanolic extract from Artemisia Argyi Folium on blood glucose and blood lipids in diabetic mice, ICR mice were induced by intraperitoneal injection of 35 mg/kg streptozotocin (STZ) and a high-carbohydrate/high-fat diet to construct type 2 diabetes mellitus model. Diabetic mice were randomly divided into three groups: the model group (5 mL/kg 0.5% CMC-Na), the Artemisia Argyi Folium ethanolic extract low-dose group (100 mg/kg ) and high-dose group (400 mg/kg ). During the treatment for 6 weeks, the amount of drinking water and food intake of mice were recorded every day. Blood glucose and body weight were recorded every week. After treatment for 6 weeks, serum total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C),and oral glucose tolerance (OGTT) were measured. The results showed that the amount of drinking water and food intake of mice significantly decreased (P < 0.01) in the Artemisia Argyi Folium ethanolic extract high-dose group; oral glucose tolerance was significantly improved (P < 0.01) and the contents of TC, TG and LDL-C were significantly decreased in the Artemisia Argyi Folium ethanolic extract low-dose group (P < 0.01). The ethanolic extract from Artemisia Argyi Folium could significantly improve the glucose and lipid metabolic disorder in T2DM mice in a dose-dependent manner.

RESUMO

Objective To investigate the correlation between the uptake of 68Ga-DOTATATE in pituitary adenoma and clinical parameters such as hormonal hypersecretion,and to evaluate the curative effect with 68Ga-DOTATATE imaging after octreotide therapy in patients with growth hormone-secreting adenoma (GH adenoma).Methods A total of 34 patients (15 males,19 females) with pituitary adenoma were recruited,including 5 adrenocorticotropic hormone-secreting adenoma (ACTH adenoma),17 GH adenoma,and 12 non-functioning adenoma (NF adenoma).In the 17 patients with GH adenoma,there were 13 patients treated by octreotide intramuscular injection 3 times with a total dose of 60 mg for 3 months.The finial diagnosis was based on histology.68Ga-DOTATATE imaging was performed,and SUV tumor volume and density index (DI) were recorded in all patients.The DI was the ratio of tumor SUVmean to tumor volume.The effective therapy was defined as more than 50% of hormonal suppression or more than 20% of tumor shrinkage.Non-parametric Mann-Whitney u test was used.Results NF adenoma showed greater tumor volume than secretory adenoma,((9.10±7.00) cm3 vs (2.92±1.60) cm3,u=43.0,P<0.05),whereas DI of secretory adenoma was higher than that of NF adenoma (7.16±4.52 vs 1.08±1.40,u=48.5,P<0.05).Additionally,DI was significantly higher(3.55±0.91 vs 1.38±0.69,u =2.0,P<0.05) in patients (n =8) with effective treatment than that in patients without effective treatment (n =5).Conclusion 68 Ga-DOTATATE may be a useful probe for PET imaging in patients with pituitary adenoma,and may be valuable for predicting the therapeutic effect of somatostatin analog treatment.
