          摘  要  目的  研究护肝布祖热方联合奥沙利铂对肝细胞癌荷瘤裸鼠的减毒增效作用及机制。方法  从40只裸鼠中选取8只作为
          空白组(生理盐水),其余32只裸鼠皮下接种人肝癌Huh7细胞构建荷瘤裸鼠模型。将造模成功的32只裸鼠随机分为模型组(生理
          盐水,灌胃)、奥沙利铂组(10 mg/kg,腹腔注射)、护肝布祖热方组(0.69 g/kg,灌胃)和联合用药组(腹腔注射10 mg/kg奥沙利铂+灌
          胃0.69 g/kg护肝布祖热方浸膏),每组8只。每天灌胃给药/生理盐水1次,连续32 d;每7天腹腔注射给药1次,共5次。实验期间,
          观察各组裸鼠一般情况,每4 d测量1次肿瘤体积;给药第30天,检测裸鼠热刺激缩足潜伏期;给药结束后,检测各组裸鼠的抑瘤
          率、脾脏系数、血常规指标以及血清中天冬氨酸转氨酶(AST)和肌酐水平,观察裸鼠肿瘤组织病理形态变化,检测肿瘤组织中微管
          相关蛋白1轻链3(LC3)、选择性自噬接头蛋白p62、B细胞淋巴瘤2(Bcl-2)、Bcl-2相关X蛋白(Bax)和胱天蛋白酶3(Caspase-3)的
          表达。结果  与模型组比较,奥沙利铂组裸鼠肿瘤体积、瘤重以及全血中白细胞、红细胞数量和脾脏系数均显著减小/降低(P<
          0.01),热刺激缩足潜伏期和血清中AST、肌酐水平均显著延长/升高(P<0.05或P<0.01)。与奥沙利铂组比较,联合用药组裸鼠肿
          瘤体积、瘤重均显著减小/降低(P<0.01),全血中白细胞、红细胞、血小板数量和脾脏系数均显著增加/升高(P<0.05或P<0.01),
          热刺激缩足潜伏期和血清中AST、肌酐水平均显著缩短/降低(P<0.01);肿瘤组织中LC3、Bax和Caspase-3蛋白的表达水平均显
          著升高(P<0.01),p62、Bcl-2蛋白的表达水平均显著降低(P<0.01)。结论  护肝布祖热方通过诱导凋亡和自噬增强奥沙利铂对裸
          鼠的抑瘤作用,并可缓解奥沙利铂引起的外周神经毒性、血液毒性、肝肾毒性和免疫器官毒性。

          ABSTRACT   OBJECTIVE  To  investigate  the  attenuation  and  synergism  of  Hugan  buzure  recipe (HBR)  combined  with
          oxaliplatin  on  hepatocellular  carcinoma  tumor  bearing  nude  mice  and  its  mechanism.  METHODS  Eight  nude  mice  were  selected
          from 40 nude mice as the blank group (normal saline), and the remaining nude mice were inoculated with hepatoma cells Huh7 to
          establish  the  tumor-bearing  model.  The  32  modeled  nude  mice  were  randomly  allocated  to  four  groups:  model  group (normal
          saline,  ig),  HBR  group (0.69  g/kg,  ig),  oxaliplatin  group (10  mg/kg,  ip),  and  combination  group (intraperitoneal  injection  of
          0.69 g/kg HBR+intragastric administration of 10 mg/kg oxaliplatin), with 8 mice in each group. Administer drug/normal saline once
          a day for 32 consecutive days; administer subcutaneous injection once every 7 days for a total of 5 times. During the experiment,
          the general condition of nude mice in each group was observed, and the tumor volume was measured every 4 days. On the 30th day
          of administration, the thermal stimulation paw withdrawal latency of nude mice in each group were detected. The tumor inhibition
          rate,  spleen  coefficient,  the  number  of  red  blood  cells,  white  blood  cells  and  platelets  in  the  whole  blood  of  nude  mice  in  each
          group,  and  the  content  of  aspartate  aminotransferase (AST)  and  creatinine  in  serum  were  detected  after  the  end  of  administration.
          HE  staining  was  used  to  observe  the  pathological  changes  in  tumor  tissues  in  nude  mice  in  each  group.  The  expression  of
