          摘  要  目的  探究“易层”贴敷对膝骨关节炎(KOA)大鼠滑膜纤维化(SF)的改善作用及潜在机制。方法  将雄性SD大鼠随机分
          为假手术组、KOA组和易层组,每组8只。KOA和易层组大鼠以前交叉韧带离断法复制KOA模型。造模14 d后,易层组大鼠于
          膝关节均匀涂抹“易层”贴敷[三色散(每100 cm 涂抹8 g)和复方三黄油膏(每100 cm 涂抹5 g)],每天贴敷8 h,连续28 d。末次给

          药后,观察各组大鼠的滑膜炎症程度及纤维化程度并进行Krenn评分,检测其滑膜组织中Ⅰ型胶原蛋白(collagenⅠ)、高迁移率族
          蛋白B1(HMGB1)、磷酸化核因子κB p65(p-NF-κB p65)蛋白的表达,血清中白细胞介素1β(IL-1β)、IL-6、肿瘤坏死因子α(TNF-
          α)的含量,以及滑膜组织中纤维化及HMGB1/Toll样受体4(TLR4)/NF-κB通路相关蛋白及mRNA的表达。结果  与假手术组比
          较,KOA组大鼠滑膜衬里细胞大量增生且排列紊乱,炎症细胞浸润和胶原纤维沉积明显;collagenⅠ、HMGB1、p-NF-κB p65阳性
          表达细胞均明显增加,血清中IL-1β、IL-6、TNF-α含量,滑膜组织中纤维化相关蛋白(转化生长因子β、collagenⅠ、金属蛋白酶组织
          抑制物1、α-平滑肌肌动蛋白)及mRNA的表达,以及HMGB1、TLR4蛋白及mRNA,p-NF-κB p65蛋白及NF-κB p65 mRNA的表达
          均显著升高(P<0.01)。与 KOA 组比较,易层组大鼠滑膜组织的病理改变明显改善,上述定量指标均显著逆转(P<0.05 或 P<
          0.01)。结论 “易层”贴敷可显著改善KOA大鼠的SF,其作用可能与抑制HMGB1/TLR4/NF-κB信号通路激活有关。

          ABSTRACT   OBJECTIVE  To  investigate  the  improvement  effect  and  potential  mechanism  of “Layers  adjusting  external
          application”  paste  on  synovial  fibrosis (SF)  in  rats  with  knee  osteoarthritis (KOA).  METHODS  Male  SD  rats  were  randomly
          divided  into  sham  operation  group,  KOA  group  and  Layers  adjusting  external  application  group,  with  8  rats  in  each  group.  KOA
          model  was  induced  by  the  anterior  cruciate  ligament  disruption  method  in  KOA  group  and  Layers  adjusting  external  application
          group.  Fourteen  days  after  modeling,  the  Layers  adjusting  external  application  group  was  given “Layers  adjusting  external
          application”  paste  [Sanse  powder (8  g  for  every  100  cm),  Compound  sanhuang  ointment (5  g  for  every  100  cm)]  on  the  knee

          joint, 8 h every day, for 28 d in total. After the last administration, the degree of synovitis and fibrosis in rats was observed, and
          Krenn  scoring  was  performed  in  each  group.  The  expressions  of  collagen  Ⅰ ,  high  mobility  group  protein  B1 (HMGB1)  and
          phosphorylated nuclear factor-κB p65 (p-NF-κB p65) were detected in the synovial membrane; the contents of interleukin-1β (IL-
          1β),  IL-6  and  tumor  necrosis  factor- α (TNF- α)  in  serum  as  well  as  the  expressions  of  fibrosis-related  and  HMGB1/Toll-like
          receptor  4 (TLR4)/NF-κB  signaling  pathway-related  proteins  and  mRNA  were  detected  in  synovial  tissue.  RESULTS  Compared
          with  the  sham  operation  group,  the  synovial  lining  cells  in  the  KOA  group  showed  significant  proliferation  and  disordered
                                                             arrangement,  the  inflammatory  cell  infiltration  and  collagen
