In Vivo:
Rats（male Sprague?Dawley rats，250?300 g，10 weeks old；65 mg/kg Streptozocin；I.P）:
A total of 20 male Sprague?Dawley rats (250?300 g, 10 weeks old) were fasted for 12 h and intraperitoneally injected with streptozotocin (65 mg/kg) to induce type I diabetes mellitus. Rats with blood glucose level above 16.7 mmol/L under normal conditions were regarded as successful diabetic animal models and were utilized for surgery.

Rats（Wistar rats；25 mg/kg Streptozotocin；i. p.）:
In some experiments, high fat diet - streptozotocin (HFD-STZ) diabetic rat were used. To this end, 4-week-old Wistar rats were fed on a 60% high fat diet (HFD) for 8 weeks and then received 25 mg/kg i. p. streptozotocin (Solarbio, China). Their blood was sampled at 13 weeks of age.

Mice （Male ICR mice (6-week old, 30±2 g) ，35mg/kg STZ，I.P， 1/week，total 4 times）:
After one week of acclimation, mice were fed with a 60% high-fat diet for hyperglycemic model induction. After 9 weeks, the HFD-fed mice were intraperitoneally injected with STZ (35 mg/kg) once a week for 4 times. One week later, the fasting blood glucose level (FBG) was measured after 12 h fasting, and the mice with FBG > 8 mM were considered as hyperglycemic model mice. Subsequently, the model group was divided into control and Up-U groups. The Up-U group was orally administered with Up-U at a dose of 200 mg/kg/day for 12 weeks. The control group was orally administered with the same amount of sterile water and all hyperglycemic model mice were fed with a 60% high-fat diet. The mice fed with a chow diet during the whole experiment were used as the blank group. The FBG levels of the mice were measured after 12 h fasting for every 4 weeks.

Mice（Male C57BL/6 J mice；55 mg/kg Streptozotocin, I.P, 3d）:
Male C57BL/6 J mice (Eight- to ten-week-old) were kept under specific pathogen-free conditions. After a fast of 12 h, mice received intraperitoneal injection of 55 mg/kg/d streptozotocin (Solarbio, Beijing, China) or equal volume of citrate buffer (0.1 M, pH = 4.5) respectively for 3 d. Mice with a fasting plasma glucose level > 16 mmol/L were chosen to use in this study. Mice were randomly divided into 3 groups: sham group, MCAO/R group and MCAO/ R + Dex group. Mice in the MCAO/R + Dex group were injected in_x005f traperitoneally with Dex (25 μg/kg) after MCAO/R surgery.
