Objective To observe the hemodynamic change of small artery in patients with type 2 diabetes. Methods We measured peak systolic velocity (PSV), end-diastolic velocity (EDV), pulse index (PI), resistance index (RI) of ocular artery (OA), central retinal artery (CRA), finger artery, dorsal pedis artery and interlobar artery of patients with early-stage type 2 diabetes. Results The decrease in PSV and EDV values occurred early in CRA of type 2 diabetics while RI and PI values increased. Conclusion The hemodynamic change of CRA occurs earliest among general small arteries of type 2 diabetic patients.

Using bioactive compounds 7-hydroxy flavone, salicylaldehyde, cinnamic acid and 4-amino-5- mercapto-1,2,4-triazoles as starting materials, three new types of flavone derivatives containing 1,2,4-triazole structure were synthesized via different step reactions. These new compounds were characterized by 1IHNMR, ESI-MS, IR and elemental analysis. Their scavenging effects on the superoxide radical (O2·-), hydroxyl radical (·OH), DPPH · radical and their total reduction activities were tested. The results showed that all of the compounds possessed some antioxidative activity at the concentration of 0.5 mg · mL(-1), but the scavenging ability of the target compounds was lower than that of the standard compound Vc.
