AIMTo study the effects of sodium magnesium fructose diphosphate (SMFD) on free calcium concentration and nitric oxide synthase activity of ischemic synaptosome, so as to explore the protective mechanisms of SMFD on cerebral ischemia.

METHODSThe synaptosomes from normal rat brain were prepared by phase partition and cultured with oxygen-glucose deprivation to establish ischemic synaptosome model. The intrasynaptosomal free calcium concentration and nitric oxide synthase activity were detected separately after the synaptosomes were co-incubated with SMFD (1.3 mmol.L-1) or fructose-1, 6-diphosphate (FDP, 4.0 mmol.L-1) for 60 min.

RESULTSSMFD decreased the free calcium concentration and reduced the activity of nitric oxide synthase (NOS) of ischemic synaptosomes. Its effects were more powerful than those of FDP.

CONCLUSIONSMFD may protect neurons from ischemic injury by preventing intracellular Ca2+ overload and inhibiting the activity of nitric oxide synthase.

OBJECTIVE:To develop a method for rapid,accurate and simultaneous determination of dexzopiclone,zolpidam and zaleplon in human plasma. METHODS:After the plasma sample was processed by liquid-liquid extraction,UPLC-MS/MS was established to detect plasma sample with carbamazepine as internal standard. The separation was performed on a Waters ACQUITY UPLC HSS T3 column with mobile phase composed of 0.1% ammonium solution-acetonitrile (gradient elution) at flow rate of 0.2 ml/min. The column temperature was set at 40 ℃,and sample size was 5 μl. The detection was performed by multiple reaction monitoring (MRM) via electrospray ionization (ESI) source in positive mode. The mass transition ion-pairs were as follows:m/z 308.2→263.1(zolpidem),m/z 389.3→245.0(dexzopiclone),m/z 306.2→236.1(zaleplon),m/z 237.3→151.2(internal standard). RE-SULTS:The linear range of zolpidem,dexzopiclone and zaleplon were 0.02-20.00,0.50-20.00,0.02-20.00 ng/ml,respectively (r=0.990 1,0.996 8,0.991 7). LLOQ of them were 0.02,0.50,0.02 ng/ml,and detection limit were 0.01,0.20,0.01 ng/ml. RS-Ds of intra-day and inter-day were all lower than 15% ;extraction recovery were 88.9% -106.5% ;matrix effect were 94.8%-106.3%. CONCLUSIONS:The method is simple,rapid,sensitive and specific,and it can be used for simultaneous deter-mination of zaleplon,zolpidem and dexzopiclone in human plasma.
