          响。方法  取50只雄性SD大鼠,通过皮下注射由牛Ⅱ型胶原、费氏完全佐剂构成的乳剂以构建诱导性关节炎模型。将造模成功
          的大鼠随机分为模型组,高良姜素低、中、高剂量组(1、5、15 mg/kg)和甲氨蝶呤组(阳性对照,2 mg/kg),每组10只;另取10只正常
          大鼠,作为正常组。从造模第15天起,各组大鼠灌胃相应药液或含0.5%吐温80的生理盐水,每天1次,连续28 d。比较灌胃前及
          灌胃后各组大鼠的关节炎指数(AI)评分和足跖趾容积;末次给药后 24 h,检测其血清中白细胞介素 6(IL-6)、肿瘤坏死因子 α
         (TNF-α)、IL-4、IL-10水平,观察踝关节滑膜组织病理变化,并检测其踝关节滑膜组织中UNC-51样激酶1(ULK1)、Beclin-1、微管
          相关蛋白 1 轻链 3(LC3)、B 细胞淋巴瘤 2(Bcl-2)、Bcl-2 相关 X 蛋白(Bax)、胱天蛋白酶 3(caspase-3)、JAK3、磷酸化 JAK3(p-
          JAK3)、STAT3、磷酸化STAT3(p-STAT3)蛋白的表达情况以及LC3阳性区域的荧光强度。结果  与模型组相比,各药物组大鼠踝
          关节滑膜组织细胞增生、炎症细胞浸润等病理变化均有所改善;其AI评分和足跖趾容积(灌胃后28 d),IL-6、TNF-α水平,Bcl-2蛋
          白的表达水平和JAK3、STAT3的磷酸化水平均显著降低(P<0.05);IL-4、IL-10水平,ULK1、Beclin-1、Bax、caspase-3、LC3蛋白的
          表达水平和LC3阳性区域的荧光强度均显著升高(P<0.05),且高良姜素的作用具有剂量依赖性(P<0.05)。结论  高良姜素可诱
          导RA大鼠滑膜组织细胞持续自噬、促进细胞凋亡、抑制滑膜细胞增生、减轻持续性炎症反应,上述抗RA作用可能与其抑制JAK3/
          STAT3通路有关。

          ABSTRACT    OBJECTIVE  To  investigate  the  effects  of  galangin  on  rheumatoid  arthritis (RA)  in  rats  by  regulating  the  Janus
          kinase  3 (JAK3)/signal  transducer  and  activator  of  transcription  3 (STAT3)  pathway.  METHODS  Fifty  male  SD  rats  were  taken,
          and an emulsion composed of bovine type Ⅱ collagen and Freund’s complete adjuvant was injected subcutaneously to establish an
          induced arthritis model. The rats that were successfully modeled were randomly divided into model group, low, medium and high
          dose  groups  of  galangin (1,  5,  15  mg/kg),  and  methotrexate  group (positive  control,  2  mg/kg),  with  10  rats  in  each  group.
          Another  10  normal  rats  were  taken  as  the  normal  group.  Starting  from  the  15th  day  of  modeling,  each  group  of  rats  was  gavaged
          with  the  corresponding  drug  solution  or  normal  saline  containing  0.5% Tween  80  once  a  day  for  28  consecutive  days. The  arthritis
          index (AI)  scores  and  paw  volume  of  rats  were  compared  before  and  after  gavage  administration. Twenty-four  hours  after  the  last
                                                              administration,  the  serum  levels  of  interleukin-6  (IL-6),
