摘 要 建立測定人腦脊液中替考拉寧濃度的在線固相萃取二維液相色譜
3.4 方法的性能分析
3.4.1 方法專屬性 分別取空白腦脊液、加標(biāo)腦脊液標(biāo)準(zhǔn)溶液及受試者樣本各400 μL,按2.4節(jié)操作,相應(yīng)譜圖見圖5。結(jié)果表明,空白腦脊液中的內(nèi)源性物質(zhì)不干擾替考拉寧和內(nèi)標(biāo)氫溴酸東莨菪堿的測定。
3.5 臨床樣本分析結(jié)果
利用本方法對來自首都醫(yī)科大學(xué)附屬天壇醫(yī)院的患者在不同時間點抽取的腦脊液樣本進(jìn)行檢測,結(jié)果如表2所示。
結(jié)果表明,替考拉寧經(jīng)注射給藥后,在人腦脊液中呈現(xiàn)較快吸收速度,但之后在體內(nèi)消除速度較慢,呈現(xiàn)較長的半衰期,這可能與替考拉寧與白蛋白高結(jié)合率所致,以上數(shù)據(jù)可為替考拉寧血藥濃度的測定和藥代動力學(xué)研究提供參考。
4 結(jié) 論
建立了在線SPE2DLCMS/MS測定人腦脊液中替考拉寧濃度的方法,并用于臨床樣本檢測。簡化了工作流程,實現(xiàn)了樣品處理和分析的自動化,提高了分析速度,能夠較好滿足腦脊液樣品分析的要求。本方法適用于監(jiān)測腦脊液中替考拉寧濃度。

Abstract A method of online solid phase extraction (SPE)two dimensional liquid chromatography electrosparytandem mass spectrometric method was established for the determination of Teicoplanin concentrations in human cerebrospinal fluid. Cerebrospinal fluid samples were treated by the online SPE treatment, and analyzed by LCMS/MS. The chromatographic separation was performed on a Shiseido CAPCALLPAK C18 column with gradient elution by using 25 mmol/L ammonium acetate (pH 6.0)acetonitrile as mobile phases, and the flow rate of 1 mL/min. Detection was carried out under the selected reaction monitoring (SRM) in positive ionization mode with scopolamine hydrobromide as internal standard. Matrixmatched calibration curves with good correlation coefficients (R2=0.9993, n=6) were obtained in the concentration range of 25-5000 μg/L. The average recoveries varied from 100.8% to 109.9%. The intra and interday precisions were less than 6%. The method is proved to be rapid, sensitive, accurate, and suitable to determine Teicoplanin concentrations in human cerebrospinal fluid.
