          摘   要  目的  研究补阳还五汤对高脂血症模型小鼠红细胞的影响。方法  以高脂饲料喂养雄性 C57BL/6 小鼠制备高脂血症模
          型。将造模成功的小鼠随机分为模型组、阿托伐他汀钙组(0.26 g/kg)、非诺贝特组(1.3 mg/kg)和补阳还五汤高、中、低剂量组
         (18.6、9.3、4.6 g/kg),每组10只;另取10只以普通饲料喂养的小鼠作为正常组。各组小鼠灌胃相应药物或生理盐水,每日1次,连
          续21 d。末次给药后,各组小鼠称体重,检测血糖、总胆固醇(TC)、甘油三酯(TAG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋
          白胆固醇(LDL-C)水平,观察红细胞形态变化,检测红细胞膜中葡萄糖转运蛋白1(GLUT1)、红细胞膜蛋白带4.2(protein 4.2)、小
          窝蛋白1(caveolin-1)、筏蛋白1(flotillin-1)的表达水平。结果  与模型组比较,补阳还五汤各剂量组小鼠体重和TC、TAG、HDL-C、
          LDL-C 水平以及 GLUT1、caveolin-1、flotillin-1 蛋白表达水平均显著降低,血糖水平和 protein 4.2 蛋白表达水平均显著升高(P<
          0.05);补阳还五汤低、中剂量组小鼠红细胞形态明显改善。结论  补阳还五汤可降低高脂血症模型小鼠的血脂水平,改善高脂环
          境中红细胞的形态及功能,有预防高脂血症并发症动脉粥样硬化的潜力。

          ABSTRACT    OBJECTIVE  To  investigate  the  effects  of  Buyang  huanwu  decoction  on  red  blood  cells  in  hyperlipidemia  model
          mice. METHODS Male C57BL/6 mice were fed a high-fat diet to prepare a hyperlipidemia model. Successfully modeled mice were
          randomly  assigned  to  the  model  group,  atorvastatin  calcium  group (0.26  g/kg),  fenofibrate  group (1.3  mg/kg),  and  high- ,
          medium-, and low- dose groups of Buyang huanwu decoction (18.6, 9.3, 4.6 g/kg), with 10 mice in each group. Additionally, 10
          mice  fed  with  regular  chow  served  as  the  normal  group.  Each  group  of  mice  received  intragastric  administration  with  the
          corresponding drug or normal saline once daily for 21 consecutive days. After the last administration, the body weight of the mice
          in  each  group  was  measured,  and  blood  glucose,  total  cholesterol (TC),  triglyceride (TAG),  high-density  lipoprotein  cholesterol
         (HDL-C),  and  low-density  lipoprotein  cholesterol (LDL-C)  levels  were  measured.  Red  blood  cell  morphology  changes  were
          observed, and the expression levels of glucose transporter type 1 (GLUT1), erythrocyte membrane protein band 4.2 (protein 4.2),
          caveolin-1, and flotillin-1 in erythrocyte membrane were determined. RESULTS Compared with the model group, the body weight
          and  levels  of TC, TAG,  HDL-C,  LDL-C,  and  the  expression  levels  of  GLUT1,  caveolin-1  and  flotillin-1  in  the  Buyang  huanwu
          decoction groups were significantly decreased, while blood glucose levels and the expression levels of protein 4.2 were significantly
          increased (P<0.05).  The  red  blood  cell  morphology  in  the  low-  and  medium-dose  groups  of  Buyang  huanwu  decoction  was
          significantly promoted. CONCLUSIONS Buyang huanwu decoction can reduce blood lipid levels in hyperlipidemia model mice and
          strengthen the morphology and function of red blood cells in a hyperlipidemic environment, which has the potential to be used for
          preventing hyperlipidemia complications such as atherosclerosis.
