          摘  要  目的  探讨加减理冲汤(MLCD)对裸鼠移植瘤细胞凋亡的作用及机制。方法  培养胃癌AGS细胞并构建裸鼠移植瘤模
          型;将裸鼠分为模型组以及MLCD低、中、高剂量组(150、300、600 mg/kg),连续灌胃蒸馏水/相应药液,每日1次,连续4周。每6 d
          测量1次裸鼠移植瘤的大小并计算移植瘤体积;给药结束后处死裸鼠并分离移植瘤组织,检测移植瘤组织中乳酸脱氢酶(LDH)、
          活性氧(ROS)含量并评估线粒体膜电位变化;观察移植瘤组织的病理形态变化;检测移植瘤组织中胱天蛋白酶(caspase)-3、cas‐
          pase-8、caspase-9酶活性,以及Fas、Fas配体(FasL)蛋白表达和caspase-3、caspase-8、caspase-9、Fas、FasL mRNA表达。结果  与模型
          组比较,MLCD各剂量组裸鼠移植瘤体积均有不同程度缩小,LDH、ROS含量以及caspase-3、caspase-8、caspase-9酶活性均显著升
          高/增强,线粒体膜电位显著降低,Fas、FasL蛋白表达以及caspase-3、caspase-8、caspase-9、Fas、FasL mRNA 表达均显著上调,以上
          指标大部分差异有统计学意义(P<0.05或P<0.01)。病理结果显示,随着MLCD给药剂量的增加,移植瘤组织中细胞的紧密程度
          逐渐下降,出现松散、碎片逐渐增多等典型的细胞凋亡形态学特征。结论  MLCD能诱导裸鼠移植瘤细胞凋亡,其作用机制可能与
          激活Fas/FasL途径及caspase凋亡途径有关。

          ABSTRACT   OBJECTIVE To investigate the effect and mechanism of modified Lichong decoction (MLCD) on the apoptosis of

          transplanted  tumor  cells  in  nude  mice.  METHODS  Human  gastric  cancer AGS  cells  were  cultured,  and  a  nude  mice  transplanted
          tumor model was established. The nude mice were divided into the model group and MLCD low-, medium- and high-dose groups
         (150,  300,  600  mg/kg).  They  were  given  distilled  water  or  the  corresponding  drug  solution  by  gavage  once  daily  for  four
          consecutive  weeks.  The  size  of  transplanted  tumors  in  nude  mice  was  measured  every  six  days,  and  the  tumor  volume  was
          calculated. After  the  medication,  the  nude  mice  were  sacrificed,  and  the  transplanted  tumor  tissues  were  isolated.  The  contents  of
          lactate dehydrogenase (LDH) and reactive oxygen species (ROS) in the transplanted tumor tissues were detected, and the changes
          in  mitochondrial  membrane  potential  were  assessed.  The  pathological  morphological  changes  were  observed.  The  enzymatic
