OBJECTIVE:To establish the method for simultaneous determination of risperidone (RIS) and 9-hydroxyrisperi-done (9-OH-RIS) in human plasma. METHODS:After liquid-liquid extraction of plasma sample,using AF2672 as internal stan-dard(IS),LC-MS/MS was adopted. The determination was performed on XtimateTM C18 column with mobile phase consisted of ace-tonitrile-10 mmol/L ammonium acetate solution(containing 0.1％ formic acid)(37:63,V/V,pH=3.2)at the flow rate of 0.25 mL/min. The column temperature was 40 ℃,and the sample size was 6 μL. The ESI was equipped and quantitative analysis was operated in positive ion and MRM mode. The mass transition ion-pairs were followed as m/z 411.26→191.02 for RIS,m/z 427.21→206.91 for 9-OH-RIS and m/z 418.00→175.95 for IS. RESULTS:The linear range of RIS was 0.2-50.0 ng/mL(r=0.9997)and 9-OH-RIS was 1.0-200.0 ng/mL (r=0.9987). RSDs of inter-day and intra-day were all lower than 15％,and the method recoveries were 92.42％-104.81％ and 94.51％-100.57％;matrix effects were 98.33％-107.09％ and 91.05％-105.80％;extraction recoveries were 78.11％-92.62％ and 76.32％-85.09％,respectively. The plasma concentrations of RIS and 9-OH-RIS in 78 schizophrenic patients were(13.58±8.31)and(25.62±15.52)ng/mL. CONCLUSIONS:The developed method is simple,sensitive and specific,which is suitable for routine drug monitoring and acute toxic analysis in patients receiving risperidone.

Objective To assess the level of radiation exposures of operators in three typical types of interventional fluoroscopic procedures.Methods Alderson Radiation Therapy (ART) phantom was used to stimulate the practices of diagnosis and therapy using TLDs for dose measurement.The radiation exposures of eye lens, neck, and breast were measured when the lead shielding of machine was on/off and the equivalent dose and effective dose to the eye lens were estimated.Results Radiation exposure of head was obviously reduced by 85% -90% when the lead shielding was on.The doses in different procedures were different.In cerebral angiography the dose equivalent of eye len was the highest in the three procedures.The annual effective dose for the operators was smaller in peripheral vascular interventions than that in cardiovascular interventional therapy and that in cerebral angiography.Conclusions The operators involved in intervention will receive an annual effective dose of less than 20 mSv as recommended by the ICRP under the protection conditions provided by the current study, except for eye lens.Attention should be paid to the protection of the eyes of operators.

Objective To investigate the effects of quetiapine and risperidone in the treatment of behavior and psychiatric symptom of dementia(BPSD).Methods 56 cases of Alzheimer's disease and vascular dementia pa- tients were all met for the classification and diagnostic criteria for mental illness in China(CCMD-3)and randomly divided into two groups(27 in quetiapine group,29 in risperidone group),experimental dosage were 0.05～0.3g/d and 1～2mg/d,respectively.The treatment lasted for 8 weeks.Results The total efficiency of quetiapine was 66.67% and that of risperidone was 65.5%,and the statistical difference was significant.As for the adverse effects, there was no significant difference,but incidence of EPS in quetiapine group was less than that of risperidone group. Conclusion Quetiapine can be widely administrated in clinic application as the high efficacy of control BPSD with low minor adverse effect.

Immuno-fluorescence technique can qualitatively determine certain nuclear translocation, of which NF-κB/ p65 implicates the activation of NF-κB signal pathways. Immuno-fluorescence analysis software with independent property rights is able to quantitatively analyze dynamic location of NF-κB/p65 by computing relative fluorescence units in nuclei and cytoplasm. We verified the quantitative analysis by Western Blot. When we applied the software to analysis of nuclear translocation in lipopolysaccharide (LPS) induced (0. 5 h, 1 h, 2 h, 4 h) primary human umbilical vein endothelial cells (HUVECs) , we found that nuclear translocation peak showed up at 2h as with calculated Western blot verification results, indicating that the inventive immuno-fluorescence analysis software can be applied to the quantitative analysis of immuno-fluorescence.
