摘 要 目的 探讨高良姜素调控Janus激酶3(JAK3)/信号转导及转录激活因子3(STAT3)通路对大鼠类风湿性关节炎(RA)的影
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),
