          摘  要  目的  筛选接骨膏促进新西兰兔骨折愈合的活性部位。方法  制备接骨膏醇提物以及乙酸乙酯部位、正丁醇部位,并与炼
          蜜调制成黏稠度适宜的膏药。以新西兰兔建立左前肢桡骨骨折模型,然后分为模型对照组、醇提物组、乙酸乙酯部位组、正丁醇部
          位组,每组6只。除模型对照组外,其余各组兔外敷接骨膏相应极性部位膏药,干预4周。通过X线检测兔骨折愈合情况,采用酶
          联免疫吸附测定法检测兔血清中白细胞介素6(IL-6)、肿瘤坏死因子α(TNF-α)、骨钙素(OC)、血管内皮生长因子A(VEGFA)、碱
          性成纤维细胞生长因子2(bFGF2)、碱性磷酸酶(ALP)水平,采用苏木素-伊红染色观察兔骨折部位病理学形态变化,采用免疫组
          化法检测兔骨折部位bFGF2蛋白的表达水平。结果  正丁醇部位组兔骨折部位的愈合速度最快,醇提物组次之,乙酸乙酯部位组
          最慢;正丁醇部位组兔血清中 TNF-α、IL-6 水平下降最快,ALP、bFGF2、OC、VEGFA 水平上升最快[且较醇提物组显著升高(P<
          0.01)],骨折部位的软骨细胞完全消失,形成大量骨髓腔,且骨髓腔内骨小梁正式形成,bFGF2表达水平也较醇提物组升高。结论
          接骨膏正丁醇部位促进兔骨折部位愈合的作用强于醇提物以及乙酸乙酯部位,是接骨膏促进骨折愈合的活性部位。

          ABSTRACT   OBJECTIVE  To  screen  the  active  site  of  Jiegu  ointment  in  promoting  fracture  healing  in  New  Zealand  rabbits.
          METHODS The ethanol extract of Jiegu ointment, as well as the ethyl acetate and n-butanol parts, were prepared and mixed with
          honey to form a plaster with appropriate viscosity. The radial fracture model of left forelimb in New Zealand rabbit was established
          and  divided  into  model  control  group,  ethanol  extract  group,  ethyl  acetate  fraction  group  and  n-butanol  fraction  group,  with  6
          rabbits  in  each  group.  Except  for  model  control  group,  rabbits  of  all  other  groups  were  treated  with  corresponding  polar  part  of
          Jiegu  ointment  for  external  application,  for  4  weeks.  The  radial  fracture  healing  of  rabbits  was  studied  by  X-ray  examination.
          Enzyme-linked immunosorbent assay was used to detect the serum levels of interleukin-6 (IL-6), tumor necrosis factor α (TNF-α),
          osteocalcin (OC),  vascular  endothelial  growth  factor  A (VEGFA),  basic  fibroblast  growth  factor  2 (bFGF2)  and  alkaline
          phosphatase (ALP).  HE  staining  was  adopted  to  observe  the  changes  of  pathological  morphology  of  rabbit  fracture  site,  and
          immunohistochemical method was used to detect the protein expression of bFGF2 in fracture site of rabbits. RESULTS The healing
          speed  of  the  fracture  site  in  the  n-butanol  fraction  group  was  the  fastest,  followed  by  ethanol  extract  group,  and  the  ethyl  acetate
          fraction  group  was  the  slowest;  the  serum  levels  of  TNF-α  and  IL-6  in  n-butanol  fraction  group  decreased  the  fastest,  while  the
          levels of ALP, bFGF2, OC and VEGFA increased the fastest [significant increase compared with ethanol extract group (P<0.01)];
          the  chondrocytes  at  the  fracture  fraction  completely  disappeared,  forming  a  large  number  of  bone  marrow  cavities,  and  the  bone
          trabeculae  in  the  bone  marrow  cavity  were  officially  formed.  The  expression  level  of  bFGF2  was  also  higher  than  ethanol  extract
          group.  CONCLUSIONS  The  effect  of  n-butanol  fraction  on  promoting  fracture  healing  is  more  significant  than  ethyl  acetate
          fraction and ethanol extract, and n-butanol fraction is the active fraction of Jiegu ointment to promote fracture healing.
