利用电化学沉积法在阳极氧化铝模板中制备了高长径比(20—100)金纳米线阵列,并用扫描俄歇电子显微镜对其结构进行了表征.紫外可见吸收光谱显示金纳米线的表面等离子共振包含横向吸收峰(transverse mode)和纵向吸收峰(longitudinal mode),具有很强的各向异性特征.纵向吸收峰的强度与入射光的偏振方向和入射角度有关,随着长径比的增加纵向吸收峰位置向高能方向移动.将纳米线之间的表面等离子体能量耦合与分子H聚合体的吸收光谱行为做了比较,认为相邻纳米线间的多重耦合使纵向吸收峰出现蓝移.利用有限元分析法模拟了电场在纳米线阵列和单根纳米线表面的不同分布.

Lopinavir Plasma Concentrations and Serum Lipids in Therapy Naïve HIV-Patients: A Sub Analysis of the FREE Study

引用

Pharmacology & Pharmacy 2012年第1期3卷 90-96页

Antiretroviral therapy in HIV patients is known for its negative effect on the cardiovascular system. One of the major adverse events in patients on lopinavir is increasing lipids. Hyperlipidaemia together with chronic inflammation by HIV-infection itself makes these patients prone for cardiovascular *** purpose of this study (a sub study within the FREE-study) was to determine if higher plasma lopinavir (LPV) concentrations lead to increase of serum lipids. Plasma drug concentrations were analysed up to week 24 in a prospective cohort of HIV antiretroviral therapy naive patients who started on a regimen of zidovudine, lamivudine and ritonavir-boosted lopinavir (FREE study). Prospectively we measured plasma lopinavir concentrations from baseline to week 24 in 72 naive HIV-patients starting on lopinavir (59 males and 13 females). A total of 210 samples were analysed, with at least 2 samples in every patient. Mean LPV trough concentration was 4.3 mg/L (± 2.1). The median intra-subject variation in LPV level was 38% (range 4% - 111%). Serum lipids were not correlated to LPV plasma concentrations possibly due to the wide intra-individual variability in LPV trough levels. Monitoring of plasma lopinavir and subsequent dose adjustment of LPV will not be useful to prevent hyperlipidaemia in HIV-patients treated with lopinavir.
