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
activities of caspase-3, caspase-8, and caspase-9, as well as
