          摘  要  目的  探讨当归补血汤调控中性粒细胞胞外诱捕网(NETs)改善卵巢早衰(POF)大鼠骨质疏松(OP)的机制。方法  将雌
          性SD大鼠随机分成正常组、模型组、骨化三醇组及当归补血汤低、中、高剂量组,每组9只。除正常组外,其余各组大鼠于第1、8天
          以6 mg/kg的剂量腹腔注射顺铂溶液建立POF并发OP模型。从造模第5天开始,各组大鼠灌胃相应药液或生理盐水,每天1次,
          连续 4 周。末次给药后,检测各组大鼠血清中雌二醇(E2 )、NETs、25-羟维生素 D3[25(OH)D3]、核因子 κB 受体激活蛋白配体
         (RANKL)、骨钙蛋白(BGP)水平,观察其骨组织病理学改变,并检测其骨组织中维生素D受体(VDR)、髓过氧化物酶(MPO)、中
          性粒细胞弹性蛋白酶(NE)、瓜氨酸化组蛋白H3(CitH3)、25羟基维生素D-1α-羟化酶(CYP27B1)、1α,25-二羟维生素D3-24-羟化酶
         (CYP24A1)蛋白的表达情况。结果  与正常组相比,模型组大鼠骨组织骨小梁数量减少、变细及断裂且连接不完整,网状结构明
          显受损,骨髓腔增大;血清中 NETs、RANKL 水平和骨组织中 MPO、NE、CitH3、CYP24A1 蛋白的表达均显著升高或上调,血清中
          E2、25(OH)D3、BGP水平和骨组织中VDR、CYP27B1蛋白的表达均显著降低或下调(P<0.05)。与模型组相比,各药物组大鼠骨
          组织病理学改变均有所恢复,多数定量指标显著改善(P<0.05)。结论  当归补血汤能够恢复 POF 并发 OP 大鼠的 E2水平,改善
          OP,其机制可能与上调VD水平、抑制NETs形成有关。

          ABSTRACT   OBJECTIVE  To  investigate  the  mechanism  through  which  Danggui  buxue  decoction  regulates  neutrophil
          extracellular traps (NETs) to improve osteoporosis (OP) in rats with premature ovarian failure (POF). METHODS Female SD rats
          were  randomly  divided  into  normal  group,  model  group,  calcitriol  group,  and  Danggui  buxue  decoction  low-dose,  medium-dose
          and  high-dose  groups,  with  9  rats  in  each  group.  Except  for  the  normal  group,  all  other  groups  were  administered  cisplatin  via
          intraperitoneal  injection  on  days  1  and  8  to  establish  a  POF  complicated  with  OP  model.  Each  group  received  the  corresponding
          drugs  or  normal  saline  intragastrically  starting  from  day  5,  once  a  day,  for  4  consecutive  weeks. After  the  last  medication,  serum
          levels of estradiol (E2 ), NETs, 25-hydroxyvitamin D3 [25(OH)D3], receptor activator of nuclear factor-κB ligand (RANKL), and
          osteocalcin (BGP)  were  measured.  The  histopathological  changes  in  bone  tissue  were  observed.  The  expressions  of  vitamin  D  receptor
         (VDR),  myeloperoxidase (MPO),  neutrophil  elastase (NE)  and  citrullinated  histone  H3 (CitH3)  in  bone  tissue  were  detected;  the
          protein  expressions  of  25-hydroxyvitamin  D-1α-hydroxylase (CYP27B1)  and  1α,25-dihydroxyvitamin  D3-24-hydroxylase (CYP24A1)
          were also determined. RESULTS Compared with the normal group, the bone tissue of rats in the model group showed a significant
          reduction in the number of trabeculae, which was thinner broken and poorly connected, with significant destruction of the reticular
          structure,  and  an  enlarged  marrow  cavity.  Serum  levels  of  NETs  and  RANKL,  the  protein  expressions  of  MPO,  NE,  CitH3  and
          CYP24A1  in  bone  tissue  were  significantly  increased  or  upregulated,  while  serum  levels  of  E2,  25(OH)D3  and  BGP  as  well  as
          protein  expressions  of  VDR  and  CYP27B1  were  significantly  decreased  or  downregulated (P<0.05).  Compared  with  the  model
          group,  the  histopathological  changes  in  the  bone  tissue  of  rats  in  each  administration  group  showed  some  degree  of  recovery,  with
          significant improvements observed in most quantitative indicators (P<0.05). CONCLUSIONS Danggui buxue decoction can restore the
                                                             E2  level  in  POF  complicated  with  OP  rats,  and  improve  OP.
