Diabetic encephalopathy (DE) is one of the severe complications in patients with diabetes mellitus. Paeonol, an active compound isolated from the root bark of Paeonia suffruticosa, has significant antidiabetic activity in vivo. However, its underlying beneficial effects on DE were unclear. In the present study, the protective activity of paeonol on DE was evaluated in streptozotocin (STZ)-induced diabetic rats. Paeonol at 50 and 100mg/kg significantly increased body weight and decreased blood glucose levels, glycosylated serum proteins, and serum advanced glycation end products (AGEs) levels. Immunohistochemistry assays and Western blot analysis revealed a significant decrease in expressions on receptor for advanced glycation end products (RAGE) and nuclear factor kappa B (NF-jB) in hippocampus and cerebral cortical neurons after paeonol treatment. Furthermore, paeonol significantly increased glutathione content and remarkedly decreased induced nitric oxide synthase activity in hippocampus tissue. Our findings indicated that paeonol could improve the pathological damage of DE in STZ-induced diabetic rats. It might be associated with the modulating AGEs/RAGE/NF-jB pathway. This study suggested that paeonol might be a promising candidate for the prevention and treatment of DE.

A novel kind of Zr-based magnetic metal-organic frameworks (MMOFs) was prepared by immobilizationof UiO-66 onto Fe3O4@SiO2 particles via an efficient one-pot solvothermal method. Subsequently, it wasused for adsorptive removal of triclosan (TCS) and triclocarban (TCC) fungicides from aqueousenvironments by magnetic solid phase separation. Morphology and physical/chemical features of theMMOFs were fully characterized by XRD, SEM, TEM, FT-IR, and VSM etc., showing high specific surfacearea, appropriate functionality, and desirable magnetic property. Several main factors affecting theadsorption performances of TCS and TCC on the MMOFs were systematically investigated and optimized,such as pH value of water sample, amounts/types of adsorbent and salinity. Under the optimizedconditions, short adsorption equilibrium time (only 25 min) and outstanding saturated adsorptioncapacities (476.27 and 602.40 mg g 1 for TCS and TCC, respectively) were the remarkable superiorities ofthe MMOFs compared with that of most reported adsorbents. The MMOFs demonstrated excellentadsorption selectivity for TCS and TCC and anti-interference ability. Also, the reusability for at least 11cycles was another major profit of the MMOFs that saved cost and prevented waste. Moreover, theMMOFs demonstrated satisfactory removal/purification ability for actual environmental water samples. These benefits propounded a promising outlook of employing the MMOFs for influential removal ofpollutants with considerable reliability in thefield of wastewater treatment.
