          摘   要  目的  探讨柴胡加龙骨牡蛎汤对难治性癫痫大鼠海马神经元损伤的影响及潜在作用机制。方法  采用侧脑室注射海人藻
          酸建立难治性癫痫大鼠模型,将难治性癫痫大鼠随机分为模型组、塞来昔布组(阳性对照)、柴胡加龙骨牡蛎汤组、柴胡加龙骨牡蛎
          汤+空载组、柴胡加龙骨牡蛎汤+环氧合酶-2(COX-2)过表达组,每组12只;另取12只大鼠为假手术组(侧脑室注射生理盐水)。各
          组给予相应的药物/生理盐水8周后,采用Racine分级标准评估大鼠癫痫发作行为学,观察海马组织CA3区病理学变化和细胞凋
          亡情况;采用酶联免疫吸附测定法检测海马组织COX-2、前列腺素E2(PGE2)、肿瘤坏死因子α(TNF-α)水平;采用比色法检测海
          马组织丙二醛(MDA)含量和超氧化物歧化酶(SOD)活性;分别采用实时荧光定量聚合酶链反应和Western blot法检测海马组织
          COX-2、P糖蛋白(P-gp)mRNA和蛋白的表达。结果  假手术组大鼠无癫痫发作;与假手术组比较,模型组大鼠癫痫Racine分级,海
          马组织细胞凋亡率,COX-2、PGE2、TNF-α水平和MDA含量以及COX-2、P-gp的mRNA和蛋白相对表达水平均显著升高,SOD活
          性显著降低(P<0.05),海马CA3区神经元出现明显损伤;与模型组比较,塞来昔布组、柴胡加龙骨牡蛎汤组大鼠癫痫Racine分级,
          海马组织细胞凋亡率,COX-2、PGE2、TNF-α水平和MDA含量以及COX-2、P-gp的mRNA和蛋白相对表达水平均显著降低,SOD
          活性均显著升高(P<0.05),海马CA3区神经元损伤减轻;与柴胡加龙骨牡蛎汤组、柴胡加龙骨牡蛎汤+空载组比较,柴胡加龙骨牡
          蛎汤+COX-2过表达组大鼠上述指标的改善被显著逆转(P<0.05),海马组织CA3区神经元损伤加重。结论  柴胡加龙骨牡蛎汤
          可能通过抑制COX-2/PGE2信号通路的激活,抑制炎症和氧化应激,从而减轻难治性癫痫大鼠海马神经元损伤。

          ABSTRACT    OBJECTIVE  To  explore  the  effect  and  potential  mechanism  of  Chaihu  longgu  muli  decoction  on  hippocampal
          neuronal  damage  in  refractory  epilepsy  rats.  METHODS  The  refractory  epilepsy  rat  model  was  established  by
          intracerebroventricular  injection  of  kainic  acid.  The  refractory  epilepsy  rats  were  randomly  assigned  into  model  group,  celecoxib
          group (positive  control),  Chaihu  longgu  muli  decoction  group,  Chaihu  longgu  muli  decoction+empty  loading  group,  Chaihu
          longgu muli decoction+cyclooxygenase-2 (COX-2) overexpression group, with 12 rats in each group. Another 12 rats were selected
          as sham operation group (injected with normal saline into the lateral ventricle). After 8 weeks of corresponding drug/normal saline
          intervention,  Racine  grading  criteria  were  applied  to  evaluate  the  seizure  behavior  of  rats;  pathological  changes  and  cell  apoptosis
          in CA3 region of hippocampal tissue were observed; ELISA method was adopted to detect the levels of COX-2, prostaglandin E2
         (PGE2), and tumor necrosis factor-α (TNF-α) in hippocampal tissue. The colorimetric method was applied to detect the content of
          malondialdehyde (MDA)  and  the  activity  of  superoxide  dismutase (SOD)  in  hippocampal  tissue.  Real-time  fluorescence
          quantitative PCR and Western blot were applied to detect the mRNA and protein expressions of COX-2 and P-glycoprotein (P-gp)
          in  hippocampal  tissue.  RESULTS  The  rats  in  the  sham  operation  group  had  no  epileptic  seizures.  Compared  with  sham  operation
          group,  Racine  grade  of  epilepsy,  apoptotic  rate  of  hippocampal  tissue  cells,  COX-2,  PGE2  and  TNF-α  levels,  MDA  contents,
          mRNA and protein levels of COX-2 and P-gp in the model group increased significantly, while SOD activity decreased significantly
         (P<0.05);  prominent  damage  was  observed  in  the  hippocampal  CA3  region.  Compared  with  model  group,  Racine  grade  of
          epilepsy,  apoptotic  rate  of  hippocampal  tissue  cells,  COX-2,  PGE2  and TNF-α  levels,  MDA  contents,  mRNA  and  protein  levels
          of  COX-2  and  P-gp  in  celecoxib  group  and  Chaihu  longgu  muli  decoction  group  decreased  significantly,  while  SOD  activity
          increased  significantly(P<0.05);  the  neuronal  damage  in  hippocampal  CA3  region  was  alleviated.  Compared  with  Chaihu  longgu
          muli  decoction  group  and  Chaihu  longgu  muli  decoction+  empty  loading  group,  the  improvement  in  the  aforementioned  indicators
                                                              in  rats  from  Chaihu  longgu  muli  decoction+COX-2
