          摘   要  目的  建立测定人全血中他克莫司(TAC)浓度的方法,并将其应用于临床。方法  采用甲醇沉淀蛋白的方法处理全血样
          品。采用液相色谱-串联质谱(LC-MS/MS)法进行测定,以子囊霉素为内标,使用Kinetex F5 100Å色谱柱,以含0.2 mmol/L甲酸的
          0.1 mmol/L醋酸铵溶液和甲醇为流动相进行梯度洗脱,流速为0.4 mL/min,进样体积为5 μL;采用电喷雾离子源在正离子模式下
          进行多反应监测(TAC m/z 821.6→768.6,子囊霉素m/z 809.4→756.1)。以2025年9月1-30日于南京医科大学附属儿童医院接受
          TAC 治疗的 83 名患儿的 86 例全血样本为研究对象,采用上述方法测定全血中 TAC 浓度,并通过 Spearman 相关性分析、Bland-
          Altman分析、Passing-Bablok回归分析评估上述方法与传统酶放大免疫分析(EMIT)法的相关性和一致性。结果  TAC的线性范围
          为 0.5~100 ng/mL,准确度、精密度、提取回收率、基质效应、稳定性试验的考察结果均符合相关要求。临床应用结果显示,LC-
          MS/MS法和EMIT法测定的患儿全血中TAC浓度的中位值分别为4.4、4.0 ng/mL,且两种方法具有强相关性(相关系数为0.848 1)
          与良好的一致性(平均相对偏差为6.5%)。结论  本研究成功建立了测定人全血中TAC浓度的LC-MS/MS法,且该法与EMIT法具
          有强相关性和良好的一致性,可用于临床治疗药物监测。

          ABSTRACT    OBJECTIVE To develop a method for the determination of tacrolimus (TAC) concentration in human whole blood
          and  to  apply  it  in  clinical  therapeutic  drug  monitoring.  METHODS  Whole  blood  samples  were  processed  by  protein  precipitation
          with  methanol.  The  determination  was  performed  using  liquid  chromatography-tandem  mass  spectrometry (LC-MS/MS),  with
          ascomycin  serving  as  the  internal  standard.  Chromatographic  separation  was  carried  out  on  a  Kinetex  F5  100Å  column  with  a
          mobile  phase  consisting  of  0.1  mmol/L  ammonium  acetate  containing  0.2  mmol/L  formic  acid  and  methanol.  Gradient  elution  was
          performed  at  a  flow  rate  of  0.4  mL/min.  The  injection  volume  was  5  μL.  Detection  was  conducted  using  multiple  reaction
          monitoring  (m/z  821.6→768.6  for  TAC;  m/z  809.4→756.1  for  ascomycin)  with  an  electrospray  ionization  source  in  positive  ion
          mode. The  study  focused  on  86  whole  blood  samples  collected  from  83  pediatric patients who  received TAC  therapy  at  Children’s
          Hospital  of  Nanjing  Medical  University  from  September  1  to  30,  2025. The  aforementioned  method  was  employed  to  measure  the
          TAC  concentration  in  the  whole  blood  samples.  The  correlation  and  agreement  between  the  aforementioned  method  and  the
          traditional enzyme multiplied immunoassay technique (EMIT) were evaluated through Spearman correlation analysis, Bland-Altman
          analysis,  and  Passing-Bablok  regression  analysis.  RESULTS  The  linear  range  of  TAC  was  0.5-100  ng/mL;  the  evaluation  results
                                                              for  accuracy,  precision,  extraction  recovery,  matrix  effect,
