          摘   要  目的  探究冲和膏促进肿疡消散的机制。方法  采取打孔法检测冲和膏对金黄色葡萄球菌、大肠埃希菌、铜绿假单胞菌、
          白色葡萄球菌、肺炎链球菌的抑菌作用。采用皮下注射金黄色葡萄球菌的方法建立皮下软组织感染大鼠模型,考察冲和膏(复方
          多黏菌素B软膏为阳性对照)干预14 d对其皮下软组织病理学变化,皮下软组织中Ⅰ型胶原、Ⅲ型胶原、基质金属蛋白酶2(MMP-
          2)、MMP-9蛋白表达量,血清中转化生长因子β(TGF-β)、碱性成纤维细胞生长因子(bFGF)含量的影响。结果  冲和膏对上述4种
          细菌(肺炎链球菌除外)均有不同程度的抑菌效果,其中对金黄色葡萄球菌的抑菌效果最好。与模型组相比,给药第7天,冲和膏
          组大鼠胶原纤维排列有序,脓液消散较快,Ⅰ型胶原、Ⅲ型胶原蛋白的表达量和TGF-β、bFGF含量均显著升高,MMP-2、MMP-9蛋
          白的表达量均显著降低(P<0.05);给药第14天,冲和膏组大鼠胶原沉积明显,皮下各附属器逐渐形成,Ⅰ型胶原、Ⅲ型胶原蛋白的
          表达量和TGF-β、bFGF含量均显著降低,MMP-2、MMP-9蛋白的表达量均显著升高(P<0.05)。结论  冲和膏具有抑菌作用,可能
          通过调控胶原纤维的合成与降解,增加脓肿组织中bFGF、TGF-β的分泌,从而起到促进肿疡消散的作用。

          ABSTRACT    OBJECTIVE  To  explore  the  mechanism  of  Chonghe  paste  promoting  the  dissipation  of  swollen  lesions.
          METHODS  The  bacteriostatic  effects  of  Chonghe  paste  against  Staphylococcus  aureus,  Escherichia  coli,  Pseudomonas
          aeruginosa,  Staphylococcus  albus  and  Streptococcus  pneumoniae  were  detected  by  punching  method.  The  subcutaneous  soft  tissue
          infection  model  of  rats  was  established  by  subcutaneous  injection  of  S.  aureus.  The  effects  of  14  d  intervention  of  Chonghe  paste
         (Compound  polymyxin  B  ointment  as  positive  control)  on  the  pathological  changes  of  subcutaneous  soft  tissue,  the  protein
          expressions  of  type  Ⅰ  collagen,  type  Ⅲ  collagen,  matrix  metalloproteinase-2 (MMP-2)  and  MMP-9  in  subcutaneous  soft  tissue,
          and  the  contents  of  transforming  growth  factor-β (TGF-β)  and  basic  fibroblast  growth  factor (bFGF)  in  serum  were  investigated.

          RESULTS  Chonghe  paste  had  varying  degrees  of  bacteriostatic  effect  on  the  above  4  bacteria (except  for  S.  pneumoniae),
          especially on S. aureus. Compared with the model group, on the 7th day of treatment, collagen fibers in the Chonghe paste group
          were arranged in an orderly manner, pus dissipated faster; the protein expressions of type Ⅰ and type Ⅲ collagen and the contents
          of TGF-β and bFGF were up-regulated significantly, while protein expressions of MMP-2 and MMP-9 were decreased significantly
         (P<0.05).  On  the  14th  day  of  administration,  collagen  deposition  was  obvious  in  the  Chonghe  paste  group,  subcutaneous
          appendages  gradually  formed;  the  protein  expressions  of  type  Ⅰ  and  type  Ⅲ  collagen  and  the  contents  of TGF-β  and  bFGF  were
          down-regulated  significantly,  while  the  protein  expressions  of  MMP-2  and  MMP-9  were  increased  significantly (P<0.05).
          CONCLUSIONS Chonghe paste has the bacteriostatic effect and may play a role in promoting the dissipation of swollen lesions by
          regulating the formation and decomposition of fibrin and increasing the secretion of bFGF and TGF-β.
