研究目的:

验证经长双歧杆菌长亚种BL21干预12周对2型糖尿病患者糖化血红蛋白(HBA1c)及肠道菌群的临床疗效。研究长双歧杆菌长亚种BL21对受试者的空腹血糖水平、血脂水平、尿酸和C反应蛋白的改善作用  

Objectives of Study:

To verify the clinical efficacy of Bifidobacterium longum subsp BL21 intervention on HBA1c and intestinal flora in patients with type 2 diabetes for 12 weeks, and to study the improvement effect of Lactobacillus rhamnosus LRa05 on fasting blood glucose level, lipid level, uric acid and C-reactive protein in subjects.
