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.

An analytical procedure for the determination of water-and methanol-extractable pentachlorophenol ( PCP) in soils using vortex assisted liquid-liquid extraction ( VALLE ) and gas chromatography ( GC ) was developed. Significant extraction parameters, such as liquid-liquid ratio and vortex speed were optimized. The recovery of PCP was the highest ( 97. 4%) at the vortex rotation speed of 2000 r/min, with good reproducbility and a small relative sdandard deviation ( RSD, 0. 5%), with regard to the volume ratio of derivatization solution to n-hexane, the recovery of PCP was 103% with an RSD of 0. 7% at 10:4. The linearity of the calibration ranged from 1. 25 μg/L to 4000 μg/L, with a correlation coefficient ( R2 ) of 0. 9999. The detection limit of the PCP in water was below 0. 2 μg/L. Compared with traditional liquid-liquid extraction ( LLE) and solid phase extraction ( SPE) , the VALLE method was more simple and more economic in terms of chemical consumption, also with a recovery of 96. 8% and a RSD of 3. 7%. Four different soils were used to check the reliability of this method. The soils were respectively extracted with water once and methanol three times. The total recoveries were 89. 5%-98. 9% and 88. 7%-98. 4% at the PCP spiking level of 1 and 10 mg/kg, respectively. It is concluded that the VALLE method satisfied the extraction and determination of water and methanol extractable PCP in soils with varying PCP polluting rates.
