Simultaneous determination of acetaminophen and oxycodone in human plasma by LC–MS/MS and its application to a pharmacokinetic study

引用

Journal of Pharmaceutical Analysis 2018年第3期8卷 160-167页

作者： Wei Lu Shunbo Zhao Meng Gong Luning Sun li ding Department of Pharmaceutical Analysis China Pharmaceutical University 24 Tongjiaxiang Nanjing 210009 PR China Nanjing Clinical Tech Laboratories Inc. 18 Zhilan Road Jiangning District Nanjing 211000 PR China Research Division of Clinical Pharmacology the First Affiliated Hospital Nanjing Medical University Nanjing 210029 PR China

A simple and rapid liquid chromatography-tandem mass spectrometry （LC-MS/MS） method was de- veloped and validated for simultaneous determination of acetaminophen and oxycodone in human plasma. Acetaminophen-d4 and oxycodone-d3 were used as internal standards. The challenge en- countered in the method development that the high plasma concentration level of acetaminophen made the MS response saturated while the desired lower limit of quantification （LLOQ,） for oxycodone was hard to reach was well solved. The analytes were extracted by protein precipitation using acetonitrile. The matrix effect of the analytes was avoided by chromatographic separation using a hydrophilic C18 column coupled with gradient elution. Multiple reaction monitoring in positive ion mode was performed on tandem mass spectrometer employing electrospray ion source. The calibration curves were linear over the concentration ranges of 40.0-8000 ng/mL and 0.200-40.0 ng/mL for acetaminophen and oxycodone, respectively. This method, which could contribute to high throughput analysis and better clinical drug monitoring, was successfully applied to a pharmacokinetic study in healthy Chinese volunteers.

First-principles study on electronic structure and optical properties of N-doped P-type β-Ga_2O_3

引用

Science China(Physics,Mechanics & Astronomy) 2012年第1期55卷 19-24页

作者： ZHANG liYing YAN Jinliang ZHANG YiJun li Ting ding XingWei School of Physics Ludong University Yantai 264025 China

The band structure, density of states, electron density difference and optical properties of intrinsic β-Ga2O3 and N-doped β-Ga2O3 were calculated using first-principles based on density functional theory. After N doping, the band gap decreases, shallow acceptor impurity levels are introduced over the top of the valence band and the absorption band edge is slightly red-shifted compared to that of the intrinsic one. The anisotropic optical properties are investigated by means of the complex dielectric function, which are explained by the selection rule of the band-to-band transitions. All calculation results indicate that N-doping is a very promising method to get P-type β-Ga2O3.

Quantitative determination of metaxalone in human plasma by LC-MS and its application in a pharmacokinetic study

引用

Asian Journal of Pharmaceutical Sciences 2016年第5期11卷 668-672页

作者： Lanting Zhao Qian li Chang Shu Keli Wang li ding China Pharmaceutical University

A simple and rapid method using liquid chromatography–mass spectrometry(LC-MS) for the determination of metaxalone in human plasma has been developed and *** was used as the internal standard(IS). The plasma samples were simply treated with acetonitrile which allowed the precipitation of plasma proteins. The chromatographic separation was achieved on a Sapphire C18(2.1 mm × 150 mm, 5 μm, Newark, USA)column using the mobile phase(5 mM ammonium acetate containing 0.01% formic acid:acetonitrile(45:55, v/v)) at a flow rate of 0.3 ml/min. The selected ion monitoring(SIM) in the positive mode was used for the determination of [M + H]+m/z 222.1 and 286.1 for metaxalone and letrozole, respectively. The standard curve obtained was linear(r2≥ 0.99)over the concentration range of 30.24-5040 ng/ml. Meanwhile, no interfering peaks or matrix effect was observed. The method established was simple and successfully applied to a pharmacokinetic study of metaxalone in healthy Chinese volunteers after a single oral dose administration of 800 mg metaxalone. The main pharmacokinetic parameters of metaxalone were as follow: Cmax,(1664 ± 1208) ng/ml and(2063 ± 907) ng/ml;AUC0-36,(13925 ± 6590) ng/ml h and(18620 ± 5717) ng/ml h;t1/2,(13.6 ± 7.7) h and(20.3 ± 7.7) h for the reference and test tablets, respectively. These pharmacokinetic parameters of metaxalone in healthy Chinese volunteers were reported for the first time.

Performance projections for ballistic carbon nanotube FinFET at circuit level

引用

Nano Research 2016年第6期9卷 1785-1794页

作者： Panpan Zhang Chenguang Qiu Zhiyong Zhang li ding Bingyan Chen lianmao Peng Key Laboratory for the Physics and Chemistry of Nanodevices and Department of Electronics Peking University Beijing 100871 China

A novel three-dimensional device structure for a carbon nanotube （CNT） fin field-effect transistor （FinFET） is proposed and evaluated. We evaluated the potential of the CNT FinFET compared with a Si FinFET at a 22-nm node at the circuit level using three performance metrics including propagation delay, total power dissipation, and energy-delay product （EDP）. Compared with a Si FinFET, the CNT FinFET presents obvious advantages in speed and EDP arising from its almost much larger current density but also results in a higher total power dissipation, especially at a low threshold voltage （V~ = 1/3Vaa）. A suitable improvement in Vth can effectively contribute to a significant suppression of leakage current and power dissipation, and then an obvious optimization is obtained in the EDP with an acceptable sacrifice in speed. In particular, CNT FinFETs with optimized threshold voltages can provide an EDP advantage of approximately 50 times over Si FinFETs under a low supply voltage （Vdd -- 0.4 V）, suggesting great potential for CNT FinFET-based integrated circuits.
