Cerebral small vessel disease（CSVD） is a common etiology of vascular cognitive impairment with no dementia（V-CIND）. Studies have revealed that cerebral microbleeds（CMBs）, a feature of CSVD, contribute to cognitive impairment. However, the association between CMBs and dementia conversion in individuals with V-CIND is still unclear. Here, we analyzed the predictive role of CMBs in the conversion from V-CIND to dementia in CSVD patients. We recruited and prospectively assessed 85 patients with CSVD and V-CIND. V-CIND was evaluated using a series of comprehensive neuropsychological scales, including the Chinese version of the Montreal Cognitive Assessment and the Clinical Dementia Rating. MRI assessments were used to quantify lacunar infarcts, white matter hyperintensities, CMBs, and medial temporal lobe atrophy. Eighty-two of the 85 patients completed the assessment for dementia conversion at a 1-year follow-up assessment. Multivariate logistic regression analyses were conducted to examine independent clinical and MRI variables associated with dementia conversion. Twenty-four patients（29.3%） had converted to dementia at the 1-year follow-up, and these individuals had significantly more CMBs in the fronto-subcortical circuits. Multivariate logistic regression analyses revealed that the patients with CMBs in the fronto-subcortical circuits（odds ratio = 4.4; 95% confidence interval： 1.602-12.081, P = 0.004） and 5 or more CMBs overall（odds ratio = 17.6, 95% confidence interval： 3.23-95.84, P = 0.001） had a significantly increased risk of dementia at the 1-year follow-up. These findings indicate that CMBs in the fronto-subcortical circuits may be predictive of dementia conversion in CSVD patients with V-CIND, and thus extend the clinical significance of CMBs.

Determination of risperidone in human plasma by HPLC-MS/MS and its application to a pharmacokinetic study in Chinese volunteers

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2008年第2期9卷 114-120页

作者： Ming-zhu HUAng jian-zhong SHENTU Jun-chun chen jian LIU Hui-li ZHOU Research Center of Clinical Pharmaceutical Science the First Affiliated Hospital School of Medicine Zhejiang University Hangzhou 310003 China

This study presents a rapid, specific and sensitive liquid chromatography/tandem mass spectrometry (LC-MS/MS) assay for determination of risperidone (RIS) in human serum using paroxetine as an internal standard (IS). An Alltima-C18 column (2.1 mm×100 mm, 3 μm) and a mobile phase consisting of 0.1% formic acid-acetonitrile (40:60, v/v) were used for separation. The analysis was performed by selected reaction monitoring (SRM) method, and the peak area of the m/z 411.3→191.1 transition for RIS was measured versus that of the m/z 330.1→192.1 transition for IS to generate the standard curves. The assay linearity of RIS was confirmed over the range 0.25～50.00 ng/ml and the limit of quantitation was 0.05 ng/ml. The linear range corresponds well with the serum concentrations of the analytes obtained in clinical pharmacokinetic studies. Intraday and interday relative standard deviations were 1.85%～9.09% and 1.56%～4.38%, respectively. The recovery of RIS from serum was in the range of 70.20%～84.50%. The method was successfully applied to investigate the bioequivalence between two kinds of tablets (test versus reference products) in 18 healthy male Chinese volunteers. The result suggests that two formulations are bioequivalent.

为探讨交通源对道路沿线大气及土壤中多环芳烃(PAHs)的影响,作者采集了道路沿线0、20、50、100、200 m不同距离梯度大气颗粒物(TSP)和土壤样品,分析两者PAHs的含量、组成和空间分布特征,通过构建PAHs的RQ-TEQ模型和土壤环境归趋模型估算多环芳烃累积生态风险影响。结果表明,200m范围内TSP中∑16PAHs的浓度范围为2.66~16.31ng/m^(3),平均值(8.17±3.51)ng/m^(3),随着与道路的距离增加,PAHs浓度呈现秋季先降低后升高再降低、春季先升高后降低的趋势,0~50 m范围内变化较大。土壤中∑16PAHs的含量为0.05~2.43 mg/kg,平均值(0.70±0.57)mg/kg,空间变化趋势与秋季TSP中PAHs基本一致,20 m处土壤中PAHs含量最低,这与行道树的遮蔽效应有关。苯并[b]荧蒽、苯并[k]荧蒽、茚苯[1,2,3-cd]芘和苯并[ghi]苝等高环PAHs含量在TSP中占比较高,土壤中则以荧蒽、芘、苯并[b]荧蒽、苯并[k]芘等中高环PAHs为主,均呈现出交通源指示特征。道路沿线200 m范围内土壤中PAHs生态风险可以忽略。不同距离处土壤中PAHs的增量随时间累积由大到小依次为50m>0m≈20m>100m>200m,10年后土壤中PAHs增加0.11~0.15mg/kg,RQ值增加10%,土壤中PAHs的累积作用使土壤生态风险增加,应引起关注。

Determination of Ultratrace Amounts of Copper(Ⅱ) in Water Samples by Electrothermal Atomic Absorption Spectrometry After Cloud Point Extraction

引用

Chemical Research in Chinese Universities 2007年第2期23卷 143-147页

作者： chen jian-guo chen neng-wu chen Shao-hong LIN Li ZHOng Ying-ying Department of Chemistry Xixi Campus Zhejiang University Hangzhou 310028 P. R. China Ningbo Entry-Exit Inspection and Quarantine Bureau Ningbo 315012 P. R. China

A novel approach was developed for the determination of ultratrace amounts of copper in water samples by using electrothermal atomic absorption spectrometry （ETAAS） after cloud point extraction （ CPE ）. 1-（ 2-Pyridylazo ） -2- naphthol was used as the chelating reagent and Triton X-114 as the mieellar-forming surfactant. CPE was conducted in a pH 8. 0 medium at 40 ℃ for 10 rain. After the separation of the phases by contrifugafion, the surfactant-rieh phase was diluted with 1 mL of a methanol solution of 0. 1 mol/L HNO3. Then 20μL of the diluted surfactant-rieh phase was injected into the graphite furnace for atomization in the absence of any matrix modifier. Various experimental conditions that affect the extraction and atomization processes were optimized. A detection limit of 5 ng/L was obtained after preconeentration. The linear dynamic range of the copper mass concentration was found to be 0-2.0 ng/mL, and the relative standard deviation was found to be less than 3. 1% for a sample containing 1.0 ng/mL Cu （ Ⅱ ）. This developed method was successfully applied to the determination of uhratraee amounts of Cu in drinking water, tap water, and seawater samples.

微生物群落在其湖泊水质调节和生物地球化学循环中发挥重要作用,其群落结构和功能受环境因素的影响.其中,抗生素会影响微生物群落的丰度、多样性、组成和功能.鉴于此,选取白洋淀为研究区域,共设置16个采样点,分别于2018年8月和2019年4月采集沉积物样品,运用超高效液相色谱-质谱联用(HPLC-MS/MS)方法测定沉积物中典型抗生素——喹诺酮类(QNs)含量,并利用高通量测序技术对沉积物中微生物群落结构及功能进行分析,探究其时空变化规律;运用冗余分析(RDA)识别微生物群落时空变化的主要影响因素.结果表明:①由2018年8月到2019年4月ω(QNs)平均值由3.91 ng·g^(-1)变为6.34 ng·g^(-1),噁喹酸(OXO)和总QNs含量季节差异显著(P<0.05);②就时间变化而言,白洋淀沉积物中主要优势菌门为变形菌(Proteobacteria)和绿弯菌(Chloroflexi),Proteobacteria相对丰度呈降低趋势,而Chloroflexi相对丰度则呈升高趋势;属水平上,8月主要优势菌属为norank_f_Anaerolineaceae和硫杆菌属,4月优势菌属为不动杆菌属和aorank_f_Anaerolineaceae,且季节差异显著(P<0.05);③就时间变化而言,Simpson指数、Chao指数、Ace指数和OTU数量均呈升高趋势,且季节差异显著(P<0.05);④就空间变化而言,各类COG功能基因无显著空间差异;就时间变化而言,能源生产和转换类、碳水化合物运输与代谢类、转录类、细胞壁/膜/包膜生物发生类和信号传导机制类功能基因季节差异显著(P<0.01和P<0.05);⑤微生物群落结构和功能基因与QNs含量呈现显著相关关系(P<0.01和P<0.05),且QNs是其主要的影响因子.因此,QNs作为白洋淀沉积物微生物群落结构和功能基因变化的主要因素,应进一步加强沉积物中抗生素污染的综合管控.
