          摘   要  目的  探讨匝迪-5味丸改善心肌缺血再灌注损伤(MIRI)的作用机制。方法  通过网络药理学方法筛选匝迪-5味丸改善
          MIRI 的潜在作用靶点和通路。将 72 只大鼠随机分为模型组、假手术组、丹参组[复方丹参滴丸 80 mg/(kg·d)]和匝迪-5 味丸高、
          中、低剂量组[1.6、0.8、0.4 g/(kg·d)],每组12只。各组大鼠灌胃相应药物,每天1次,连续14 d。末次给药后,结扎大鼠左冠状动脉
          前降支建立MIRI模型,假手术组大鼠只穿线不结扎。检测建模后各组大鼠血清中肌酸激酶(CK)、乳酸脱氢酶(LDH)、天冬氨酸
          转氨酶(AST)、心肌肌钙蛋白T(CTn-T)的含量,心肌细胞凋亡率,心肌组织中磷脂酰肌醇3-激酶(PI3K)、蛋白激酶B(Akt)、B淋巴
          细胞瘤2(Bcl-2)及Bcl-2相关X蛋白(Bax)、胱天蛋白酶3(caspase-3)蛋白表达水平;观察心肌组织形态变化。结果  共获得匝迪-5
          味丸的活性成分177个,作用靶点220个,参与改善心肌缺血相关的靶点51个,其中核心靶点为AKT1,涉及PI3K-Akt、内质网、缺
          氧诱导因子-1等多个通路。与模型组比较,丹参组和匝迪-5味丸高剂量组大鼠血清中CK、LDH、AST、CTn-T含量和心肌细胞凋
          亡率,以及心肌组织中caspase-3、Bax蛋白表达水平均显著降低(P<0.05或P<0.01),心肌组织中PI3K、Akt、Bcl-2蛋白表达水平
          均显著升高(P<0.05或P<0.01),心肌组织病理形态改变均明显改善;匝迪-5味丸低、中剂量组大鼠上述指标亦有不同程度改善。
          结论  匝迪-5味丸可能通过激活PI3K-Akt信号通路抑制细胞凋亡,从而发挥改善MIRI的作用。

          ABSTRACT    OBJECTIVE  To  explore  the  mechanism  of  Zadi-5  pill  in  improving  myocardial  ischemia-reperfusion  injury
         (MIRI).  METHODS  The  targets  and  pathways  of  potential  effects  of  Zadi-5  pill  improving  MIRI  were  screened  based  on  the
          network  pharmacology.  Seventy-two  rats  were  randomly  divided  into  model  group,  sham  operation  group,  Danshen  group
          [Compound danshen dripping pills 80 mg/(kg·d)] and Zadi-5 pill high-dose, medium-dose and low-dose groups [1.6, 0.8, 0.4
          g/(kg·d)], with 12 rats in each group. The rats in each group were given corresponding drugs intragastrically, once a day, for 14
          consecutive  days.  After  the  last  administration,  MIRI  model  was  established  by  ligating  the  anterior  descending  branch  of  left
          coronary  artery  in  rats,  while  rats  in  the  sham  operation  group  were  threaded  without  ligation.  The  contents  of  creatine  kinase
         (CK),  lactate  dehydrogenase (LDH),  aspartate  transaminase (AST),  cardiac  troponin  T (CTn-T),  apoptotic  rate  of
          cardiomyocyte,  phosphatidylinositol  3-kinase (PI3K),  protein  kinase  B (Akt),  B-cell  lymphoma-2 (Bcl-2),  Bcl-2  related  X
          protein (Bax)  and  caspase-3  in  myocardial  tissue  were  detected  in  each  group  after  modeling;  the  morphological  changes  of
          myocardial  tissue  were  observed.  RESULTS  A  total  of  177  active  ingredients  and  220  targets  of  Zadi-5  pill  were  obtained,
          including  51  targets  involved  in  improving  myocardial  ischemia;  the  core  target  of  Zadi-5  pill  improving  MIRI  was  AKT1,
          including  PI3K-Akt,  endoplasmic  reticulum  and  hypoxia-inducible  factor-1.  Compared  with  model  group,  the  contents  of  CK,
          LDH,  AST  and  CTn-T,  the  apoptotic  rate  of  cardiomyocyte  as  well  as  the  protein  expressions  of  caspase-3  and  Bax  were
          significantly  decreased  in  Danshen  group  and  Zadi-5  pill  high-dose  group (P<0.05  or  P<0.01),  while  the  protein  expressions  of
          PI3K,  Akt  and  Bcl-2  in  myocardial  tissue  were  significantly  increased (P<0.05  or  P<0.01),  respectively;  the  myocardial
          histopathological  changes  were  significantly  improved.  The  above  indicators  were  improved  to  varying  degrees  in  Zadi-5  pill  low-
                                                              dose  and  medium-dose  groups,  too.  CONCLUSIONS  Zadi-5
