          摘   要  目的  建立同时测定脊柱结核患者血浆中3种抗结核药物浓度的方法,并将该法应用于临床。方法  以苯海拉明为内标,
          采用液相色谱-串联质谱(LC-MS/MS)技术建立同时测定脊柱结核患者血浆中异烟肼、利福平和吡嗪酰胺浓度的方法。以Chema‐
          link CM-C18T为色谱柱,0.1%甲酸-甲醇溶液为流动相进行梯度洗脱,流速为0.4 mL/min,进样体积为2 μL;采用电喷雾离子源在正
          离子模式下进行多反应监测,用于定量分析的离子对分别为 m/z 138.0→121.0(异烟肼)、m/z 823.3→791.3(利福平)、m/z 124.1→
          79.0(吡嗪酰胺)、m/z 256.0→167.0(苯海拉明)。选择2023年1月-2025年6月在青海省人民医院住院的53例脊柱结核患者,采用
          上述方法测定患者血浆中异烟肼、利福平和吡嗪酰胺浓度。结果  异烟肼、利福平和吡嗪酰胺的线性范围分别为0.5~16、2~64、
          2.5~80 μg/mL(r 不低于 0.998 7),准确度为 90.20%~108.64%(n=5),日内精密度的 RSD 均小于 6.63%(n=5),日间精密度的
          RSD均小于8.42%(n=3),基质效应为88.60%~115.41%(n=5),稳定性试验的相对偏差均在±15%范围内,残留效应对测定无干
          扰。临床应用结果显示,脊柱结核患者体内异烟肼、利福平、吡嗪酰胺的平均血药浓度分别为(3.62±2.80)、(8.55±4.57)、
         (20.12±6.56)μg/mL,血药浓度低于有效峰浓度的发生率分别为49.06%、58.49%、60.38%。结论  本研究所建立的方法快速准确、
          稳定性好,可用于临床监测脊柱结核患者血浆中异烟肼、利福平和吡嗪酰胺的浓度。

          ABSTRACT    OBJECTIVE  To  establish  a  method  for  simultaneously  determining  three  anti-tuberculosis  drugs  in  the  plasma  of
          patients  with  spinal  tuberculosis  and  apply  it  in  clinical  practice.  METHODS  LC-MS/MS  method  was  established  for  the
          quantitative  determination  of  the  concentrations  of  isoniazid,  rifampicin  and  pyrazinamide  in  the  plasma  of  patients  with  spinal
          tuberculosis, using diphenhydramine as the internal standard. The determination was carried out using Chemalink CM-C18T column,
          with  mobile  phase  consisting  of  0.1%  formic  acid-methanol  solution (gradient  elution),  at  the  flow  rate  of  0.4  mL/min  and  an
          injection volume of 2 μL. Multiple reaction monitoring was conducted using an electrospray ionization source in positive ion mode.
          The ion pairs used for quantitative analysis were m/z 138.0→121.0 (for isoniazid), m/z 823.3→791.3 (for rifampicin), m/z 124.1→
          79.0 (for  pyrazinamide),  and  m/z  256.0→167.0 (for  diphenhydramine).  Fifty-three  patients  diagnosed  with  spinal  tuberculosis  in
          Qinghai  Provincial  People’s  Hospital  from  January  2023  to  June  2025  were  selected,  and  the  plasma  concentrations  of  isoniazid,
          rifampicin  and  pyrazinamide  in  these  patients  were  measured  using  the  above  method.  RESULTS  The  linear  ranges  for  isoniazid,
                                                              rifampicin  and  pyrazinamide  were  0.5-16,  2-64,  and  2.5-80
