          摘  要  目的  基于磷脂酰肌醇3激酶(PI3K)/蛋白激酶B(Akt)信号通路,探讨复方蜥蜴散调控糖酵解降低胃癌顺铂耐药性的效
          应机制。方法  体外培养人胃癌MKN45、MKN45/DDP(顺铂耐药)细胞,以不同质量浓度顺铂(0.1、0.2、0.4、0.8、1.6、3.2 μg/mL)干
          预,检测其存活率、半数抑制浓度(IC50 )和耐药指数。于裸鼠右前腋窝皮下接种MKN45/DDP细胞悬液制备胃癌耐药裸鼠移植瘤
          模型,将造模成功的裸鼠随机分为模型组、顺铂组(0.002 g/kg)、复方蜥蜴散组(2.8 g/kg)、联合组(剂量同各单药组),每组8只;各
          药物组裸鼠给予相应药液,每周2次(顺铂,腹腔注射)或每天2次(复方蜥蜴散,灌胃),连续4周。实验期间,监测各组裸鼠体重并
          计算其肿瘤体积和肿瘤生长抑制率,检测其肿瘤组织中炎症因子(肿瘤坏死因子 α、白细胞介素 6)水平,多药耐药相关蛋白 1
         (MRP1)、P糖蛋白(P-gp)、葡萄糖转运蛋白 1(GLUT1)、乳酸脱氢酶 A(LDHA)mRNA 及蛋白,以及 PI3K、磷酸化 PI3K(p-PI3K)、
          Akt、磷酸化 Akt(p-Akt)、己糖激酶2(HK2)、丙酮酸激酶M2(PKM2)蛋白的表达情况。结果  在不同质量浓度顺铂的干预下,耐药细
          胞MKN45/DDP的存活率均显著高于亲本细胞MKN45(P<0.05);MKN45/DDP和MKN45细胞的IC50分别为(1.052 0±0.221 9)、
         (0.372 1±0.238 0)μg/mL,耐药指数为2.827。与模型组比较,顺铂组、复方蜥蜴散组、联合组裸鼠的肿瘤生长均受到不同程度的抑
          制,肿瘤生长抑制率显著升高(P<0.05);肿瘤组织中炎症因子水平,MRP1、P-gp、GLUT1、LDHA mRNA及蛋白的表达(顺铂组除
          外),PI3K、Akt蛋白的磷酸化水平(顺铂组除外),以及HK2、PKM2蛋白的表达均显著降低或下调,且联合组的效果显著优于顺铂
          组(P<0.05)。结论  复方蜥蜴散可通过减少肿瘤相关炎症因子的分泌,抑制糖酵解、耐药相关蛋白及基因的表达,抑制PI3K/Akt
          信号通路的活化来抑制胃癌耐药细胞移植瘤裸鼠的肿瘤生长,具有一定的顺铂增效及逆转耐药的作用。

          ABSTRACT   OBJECTIVE  To explore the mechanism of Compound lizard powder reducing cisplatin resistance in gastric cancer
          by  regulating  glycolytic  activity  based  on  phosphoinositide  3-kinase(PI3K)/protein  kinase  B(Akt)  signaling  pathway.  METHODS
          Human gastric cancer MKN45 and MKN45/DDP (cisplatin-resistant) cells were cultured in vitro and intervened with different mass
          concentrations of cisplatin (0.1, 0.2, 0.4, 0.8, 1.6, 3.2 μg/mL) to detect the survival rate, half inhibitory concentration (IC50 ) and
          drug  resistance  index.  MKN45/DDP  cells  were  inoculated  subcutaneously  in  the  right  anterior  axilla  of  nude  mice  to  prepare  a
          transplanted  tumor  model  of  gastric  cancer.  After  successful  modeling,  they  were  randomly  divided  into  model  group,  cisplatin
          group (0.002  g/kg),  Compound  lizard  powder  group (2.8  g/kg)  and  combination  group (the  same  dose  as  each  single  drug
          group), with 8 nude mice in each group. Each administration group was given relevant solution, twice a week (cisplatin, i.p.) or
                                                             twice  a  day  (Compound  lizard  powder,  i. g.) ,  for  4
