          摘  要  目的  探究不同肠道微环境下奈妥匹坦帕洛诺司琼胶囊(NEPA)对大鼠注射用紫杉醇(白蛋白结合型)(简称“白蛋白紫杉
          醇”)药动学的影响。方法  将雄性SD大鼠分为正常组和模型组,每组16只。模型组大鼠灌胃万古霉素溶液构建肠道紊乱大鼠模
          型。造模后次日,分析其肠道菌群多样性,并检测其小肠及肝组织中细胞色素P450 3A1(CYP3A1)、CYP2C11 mRNA及肝组织中
          上述蛋白的表达。将雄性SD大鼠按前述方法分组,每组16只;将正常组分为TP化疗组(TP-1组)、TP化疗+NEPA组(TP+NEPA-1
          组),将模型组大鼠随机分为TP化疗组(TP-2组)、TP化疗+NEPA组(TP+NEPA-2组),每组8只。TP+NEPA-1组和TP+NEPA-2组
          大鼠分别单次灌胃NEPA混悬液25.8 mg/kg(以奈妥匹坦计);1 h后,4组大鼠均单次尾静脉注射白蛋白紫杉醇和顺铂药液。于末
          次给药后的不同时间点采集血样,以阿奇霉素为内标,采用液相色谱-串联质谱法检测血浆中紫杉醇的质量浓度,并采用DAS 2.0
          计算其主要药动学参数并进行组间比较。结果  与正常组大鼠相比,模型组大鼠的Chao1、Shannon指数均显著降低(P<0.05),菌
          群组成及相对丰度变化明显;其肝组织中 CYP3A1 mRNA、小肠及肝组织中 CYP2C11 mRNA 的表达均显著下调(P<0.05)。与
          TP-1组比较,TP-2组大鼠体内紫杉醇的药时曲线下面积(AUC0-t、AUC0-∞)、平均滞留时间(MRT0-t ),TP+NEPA-1组及TP+NEPA-2
          组大鼠体内紫杉醇的达峰浓度(cmax )、AUC0-t、AUC0-∞均显著升高或延长;TP-2组大鼠体内紫杉醇的清除率(CL),TP+NEPA-1组及
          TP+NEPA-2组大鼠体内紫杉醇的表观分布容积(Vd )、CL均显著降低或缩短(P<0.05)。与TP-2组比较,TP+NEPA-2组大鼠体内
          紫杉醇的cmax显著升高,Vd、MRT0-t均显著降低或缩短(P<0.05)。结论  肠道菌群紊乱会影响CYP3A1、CYP2C11 mRNA的表达,
          导致紫杉醇在大鼠体内的清除减慢,暴露量增加;肠道菌群正常时,联用NEPA可增加紫杉醇在大鼠体内的暴露量;肠道菌群紊乱
          时,联用NEPA对紫杉醇体内暴露量的影响有限。

          ABSTRACT   OBJECTIVE  To  investigate  the  impact  of  Netupitant  and  palonosetron  hydrochloride  capsules (NEPA)  on  the
          pharmacokinetics  of  Paclitaxel  for  injection  (albumin  bound)  (i. e.  albumin-bound  paclitaxel)  under  different  intestinal
          microenvironment conditions. METHODS Male SD rats were divided into a normal group and a model group (n=16). Rats in the
          model  group  were  intragastrically  administered  vancomycin  solution  to  establish  an  intestinal  disorder  model.  The  next  day  after
          modeling,  intestinal  microbiota  diversity  was  analyzed,  and  the  mRNA  expressions  of  cytochrome  P450  3A1 (CYP3A1)  and
          CYP2C11 in small intestine and liver tissues as well as those protein expressions in liver tissue were measured. Male SD rats were
          grouped as described above (n=16). The normal group was subdivided into the TP chemotherapy group (TP-1 group) and the TP
          chemotherapy+NEPA group (TP+NEPA-1 group); the model group was subdivided into the TP chemotherapy group (TP-2 group)
          and  the  TP  chemotherapy+NEPA  group (TP+NEPA-2  group) (n=8).  Rats  in  the  TP+NEPA-1  and  TP+NEPA-2  groups  received  a
          single  intragastric  dose  of  NEPA  suspension (25.8  mg/kg,  calculated  by  netupitant).  One  hour  later,  all  four  groups  received  a
                                                             single  tail  vein  injection  of  albumin-bound  paclitaxel  and
