          摘   要  目的  探讨丹参饮对高脂血症模型大鼠血脂异常的调节机制。方法  实验大鼠分为空白组(n=9,不造模)、模型组(n=8,
          造模)和丹参饮组(n=9,造模)。于高脂饲料喂养第9周开始,丹参饮组大鼠灌胃相应药液(3.6 g/kg),空白组和模型组大鼠灌胃等
          体积生理盐水,每天1次,连续4周。给药4周后,检测各组大鼠血浆甘油三酯(TG)、胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)
          和高密度脂蛋白胆固醇(HDL-C)水平;观察大鼠肝脏组织病理形态学变化;采用TMT定量蛋白质组学分析筛选出样本间的差异
          蛋白;检测大鼠肝脏组织关键差异蛋白环氧化物水解酶 2(EPHX2)、围脂滴蛋白 2(PLIN2)、过氧化物酶体增殖物激活受体 γ
         (PPARγ)、糖原合成酶激酶3β(GSK-3β)表达情况。结果  与模型组比较,丹参饮组大鼠血浆TC、TG、LDL-C水平均显著降低(P<
          0.05),HDL-C水平显著升高(P<0.05)。模型组大鼠肝脏组织染色不均,肝板排列紊乱,肝血窦消失,部分细胞的细胞核固缩或消
          失,细胞质肿胀、融合,结缔组织增生,呈现弥散性空泡样脂肪滴改变;丹参饮组大鼠肝脏组织上述病理形态均有不同程度的改善。
          差异蛋白分析结果显示,模型组与空白组比较,差异蛋白总数为298个;丹参饮组与模型组比较,差异蛋白总数为139个。与模型
          组比较,丹参饮组大鼠肝脏组织中EPHX2、PLIN2蛋白表达水平均显著降低(P<0.01),GSK-3β、PPARγ蛋白表达水平均显著升高
         (P<0.01)。结论  丹参饮对高脂血症模型大鼠血脂水平和肝脏病理形态学均有显著的改善作用,其调节机制可能与上调PPARγ、
          GSK-3β表达和下调EPHX2、PLIN2表达有关,涉及的信号通路可能包括PPARγ信号通路。

          ABSTRACT    OBJECTIVE  To explore the regulatory mechanism of Danshen decoction on dyslipidemia in hyperlipidemia model
          rats. METHODS The experimental rats were divided into blank group (n=9, no modeling), model group (n=8, modeling), and
          Danshen  decoction  group (n=9,  modeling).  Starting  from  the  9th  week  of  feeding  with  the  high-fat  diet,  rats  in  the  Danshen
          decoction  group  were  given  the  corresponding  medication  solution (3.6  g/kg)  intragastrically,  while  blank  group  and  model  group
          were given equal volume of normal saline, once a day, for 4 consecutive weeks. After 4 weeks of administration, the plasma levels
          of  triglycerides (TG),  total  cholesterol (TC),  low-density  lipoprotein  cholesterol (LDL-C),  and  high-density  lipoprotein
          cholesterol (HDL-C)  were  measured  in  each  group  of  rats;  the  pathological  and  morphological  changes  of  liver  tissue  were
          observed;  the  differential  proteins  between  samples  were  screened  out  by  TMT  quantitative  proteomic  analysis;  the  expression
          levels  of  the  key  differentially  expressed  proteins  in  the  liver,  including  epoxide  hydrolase  2 (EPHX2),  perilipin  2 (PLIN2),
          peroxisome  proliferator  activated  receptor  γ (PPAR  γ)  and  glycogen  synthase  kinase-3β (GSK-3β)were  detected.  RESULTS
          Compared  with  the  model  group,  the  plasma  levels  of  TC,  TG  and  LDL-C  in  the  Danshen  decoction  group  were  significantly
                                                              reduced  (P<0.05) ,  while  the  level  of  HDL-C  was
