A method for the determination of seven kinds of thiocarbamate herbicides, molinate, pebulate, vernolate, triallate, thibencarb, eradicane and butylate in black tea and green tea has been developed. After homogenization, 2.0 g tea sample was soaked with 6 mL water for 1 h. 2.5 g NaCl was then added, and the sample was extracted twice by 20 mL acetonitrile. After concentration, the extract was put through HLB column and eluted by 3 mL acetonitrile. The eluate was then concentrated and dissolved with 2.0 mL hexane-acetone (7∶ 3, V/V) mixture. The preparation was cleaned by Envi-Carb column and eluted with 5 mL hexane-acetone. After concentration, the residue was dissolved by acetonitrile-water (5∶ 5, V/V) solution. Detection was achieved by electrospray ionization(ESI) in positive mode using multiple reaction monitoring. D_3-carbaryl was used as the internal standard, the linear range for the herbicides was 0-200 μg/L and the limit of detection were from 0.093 to 1.77 μg/L, with the correlation coefficients(r) varying from 0.9954 to 0.9988. The recoveries of all thiocarbamate herbicides were from 77.3% to 91.5% at the spiked levels of 5-20 μg/kg. The RSD of each compound was less than 15%. Black tea and green tea samples were successfully analyzed by the proposed method with satisfactory results.

OBJECTIVE To investigate the protective effects and mechanism of diterpene ginkgolides meglumine injection (DGMI) against oxidative stress induced by oxygen-glucose deprivation (OGD) in SH-SY5Y cells. METHODS SH-SY5Y cells were divided into five groups: normal control, model control (OGD group) and drug(25 mg · L- 1) administration groups including DGMI group, extract of ginkgo biloba leaves injection group (EGBLI) and lactones ginkgo biloba injection group (LGBI). The cells suffered from oxygen-glucose deprivation (OGD) for 4 h, followed by reoxygenation with drugs for 6 h. Then, cell viabilities were detect using CCK-8 assays, reactive oxygen species (ROS) levels using fluorescence probe DCFH-DA and superoxide dismutase (SOD) activities using WST-1 test. Western blotting was used to detected protein levels of hemeoxygenase-1(HO-1), NAD(P)H, quinone oxidore?ductase l (Nqo1), protein kinase B (Akt), phosphorylated Akt (p-Akt), nuclear factor-E2-related factor2 (Nrf2) and phosphorylated Nrf2 (p-Nrf2). The cells were induced by OGD for 4 h, followed by reoxygen?ation and DGMI for 1 h, combined with different concentrations of PI3K inhibitor (LY294002) (at the final concentration of 12.5, 25 and 50 μmol · L-1) before the protein levels of AKT, p-AKT, Nrf2 and p-Nrf2 were detected by Western blotting. RESULTS SH-SY5Y cells induced by OGD for 4 h resulted in an increase in ROS(P<0.01), but a decrease in cell viabilities(P<0.01), SOD activities(P<0.01), and antioxidant protein levels ( Akt, p-Akt, Nrf2, p-Nrf2, HO-1 and Nqo1) (P<0.01). Compared with OGD group, treatment with reoxygenation and drugs (DGMI,EGBLI and LGBI respectively) for 6 h resulted in a decrease in ROS (P<0.01), but an increase in cell viabilities, SOD activities and antioxidant protein levels of p-Nrf2, HO-1, Nqo1 and p-Akt(P<0.05,P<0.01). DGMI group showed the best efficiently. Moreover, after OGD for 4 h, compared with DGMI group, combining reoxygenation and DGMI with LY294002 for 1 h resulted in a concentration-dependent inhibition of the protein levels of p-AKT and p-Nrf2(P<0.01). CONCLUSION DGMI 25 mg · L-1 can inhibit oxidative stress in SH-SY5Y cells induced by OGD by increasing the activity and expression of Nrf2 through PI3K/Akt pathway, which may be one of the mechanisms by which DGMI protects neurons from stroke.

A novel series of fingolimod analogues containing diphenyl ether moiety were designed and synthesized based on the modification of immunosuppressive agent fingolimod used in the treatment of multiple sclerosis. Compounds were evaluated in vivo for lymphopenic activity and heart rate affection. Most compounds showed moderate lymphopenic activity. It is worth noting that compounds 6c, 6d and 14c-14e showed considerable immunosuppressive activities comparable to fingolimod. And compound 14e had no effect on heart rate.
