          摘   要  目的  基于Z-DNA结合蛋白1(ZBP1)/混合谱系激酶结构域样蛋白(MLKL)信号通路探讨温脾通络开窍方对阿尔茨海默
          病(AD)小鼠神经元坏死性凋亡的影响及机制。方法  将40只APP/PS1转基因AD小鼠随机分为模型组,温脾通络开窍方低、高剂
          量组(10.4、20.8 g/kg,以生药量计)和盐酸多奈哌齐组(阳性对照,3 mg/kg),每组10只;并以10只C57BL/6J小鼠作为正常对照组。
          灌胃给药,每天1次,连续30 d。末次给药24 h后通过Morris水迷宫实验评估小鼠学习记忆能力,观察海马组织病理形态,检测血
          清中肿瘤坏死因子α(TNF-α)、白细胞介素4(IL-4)水平,检测海马组织中Tau蛋白、淀粉样前体蛋白(APP)和ZBP1/MLKL信号通
          路相关蛋白表达水平,检测海马组织神经元内磷酸化受体相互作用蛋白激酶3(p-RIPK3)阳性表达及海马组织中ZBP1 mRNA相
          对表达水平。结果  与正常对照组比较,模型组小鼠第3~5天的逃避潜伏期均显著延长(P<0.05),穿越平台次数显著减少(P<
          0.05),海马组织出现明显病理性改变;TNF-α水平,APP、p-Tau、ZBP1蛋白表达水平和RIPK1、RIPK3、MLKL蛋白磷酸化水平,p-
          RIPK3荧光强度和ZBP1 mRNA相对表达水平均显著升高(P<0.05);血清中IL-4水平显著降低(P<0.05)。与模型组比较,各给
          药组小鼠上述指标水平均显著逆转(P<0.05),海马组织病理损伤减轻。结论  温脾通络开窍方可通过抑制ZBP1/MLKL信号通
          路,减少AD小鼠神经元坏死性凋亡,抑制炎症反应,进而改善AD小鼠学习和空间记忆能力。

          ABSTRACT    OBJECTIVE To investigate the effects and mechanism of Wenpi tongluo kaiqiao formula (WPTL) against neuronal
          necroptosis  in Alzheimer’s  disease (AD)  mice  based  on  the  Z-DNA  binding  protein  1 (ZBP1)/mixed  lineage  kinase  domain-like
          protein (MLKL)  signaling  pathway.  METHODS  Forty  APP/PS1  transgenic  AD  mice  were  randomly  divided  into  model  group,
          WPTL  low-dose (WPTL-L)  group (10.4  g/kg,  calculated  by  the  raw  medicine), WPTL  high-dose (WPTL-H)  group (20.8  g/kg,
          calculated by the raw medicine) and donepezil hydrochloride group (3 mg/kg), with 10 mice in each group; another 10 C57BL/6J
          mice  were  selected  as  normal  control  group.  Intragastric  administration,  once  a  day,  for  30  consecutive  days.  Twenty-four  hours
          after  the  last  administration,  Morris  water  maze  test  was  performed  to  evaluate  learning  and  memory  abilities;  the  pathological
                                                              morphology  of  hippocampal  tissues  was  observed;  the  serum
