          摘   要  目的  研究芥子碱硫氰酸盐可溶性微针(ST-DMN)穴位给药抗支气管哮喘(BA)的疗效。方法  采用网络药理学方法和分
          子对接技术筛选芥子碱硫氰酸盐(ST)抗BA的核心靶点,并针对排名前3位的核心靶点进行药效学研究。首先制备ST-DMN(ST
          载药量为1 mg/片),再将30只大鼠分为空白对照组、模型对照组、空白微针组、白芥子散敷贴组(阳性对照组)和ST-DMN组,除空
          白对照组外,其余各组大鼠采用10%卵清蛋白(含氢氧化铝佐剂)致敏和1%卵清蛋白雾化激发以复制BA模型。造模成功后,空
          白对照组大鼠不处理,模型对照组大鼠于肺俞穴、大椎穴涂抹生理盐水,空白微针组、白芥子散敷贴组、ST-DMN组大鼠分别于相
          同穴位给予空白微针、白芥子散(敷贴,1.5 g)、ST-DMN(2个穴位共给予3片)处理,每天1次,连续28 d。给药结束后,观察大鼠一
          般症状并测定体质量,观察大鼠肺组织的病理学形态变化,检测大鼠血清、支气管肺泡灌洗液(BALF)、肺组织中前列腺素内过氧
          化物合酶2(PTGS2)、基质金属蛋白酶9(MMP-9)、白细胞介素2(IL-2)的水平。结果  网络药理学和分子对接结果显示,ST抗BA
          的关键靶点有PTGS2、MMP-9、IL-2、表皮生长因子受体、热休克蛋白90AA1等。药效实验结果显示,与模型对照组比较,ST-DMN
          组大鼠咳嗽减轻,毛色恢复,行为灵敏,呼吸平稳,体质量增加;肺组织结构、肺泡上皮细胞、肺间质炎症细胞浸润等病理变化均得
          到不同程度的改善;血清、BALF、肺组织中PTGS2、MMP-9、IL-2水平均明显降低(P<0.05或P<0.01)。结论  ST-DMN穴位给药
          抗BA的效果良好,其作用机制可能与下调血清、BALF、肺组织中PTGS2、MMP-9、IL-2水平有关。

          ABSTRACT    OBJECTIVE  To  study  the  efficacy  of  sinapine  thiocyanate  dissoluble  microneedle (ST-DMN)  for  acupoint
          administration  against  bronchial  asthma (BA).  METHODS  The  network  pharmacology  and  molecular  docking  techniques  were
          used  to  screen  the  core  targets  of  sinapine  thiocyanate (ST)  against  BA,  and  the  pharmacodynamics  of  the  top  3  core  targets  was
          studied.  Firstly,  ST-DMN  was  prepared (drug  loading  of  ST  was  1  mg/tablet);  secondly,  30  rats  were  divided  into  blank  control
          group,  model  control  group,  blank  microneedle  group,  Sinapine  powder  plaster  group (positive  control  group)  and  ST-DMN
          group.  Except  for  the  blank  control  group,  rats  of  other  groups  were  sensitized  with  10%  ovalbumin (containing  aluminum
          hydroxide  adjuvant)  and  nebulized  with  1%  ovalbumin  to  induce  the  BA  model.  After  modeling,  blank  control  group  did  not
          receive  any  intervention;  normal  saline  was  applied  to  the  Feishu  acupoint  and  Dazhui  acupoint  of  the  rats  in  the  model  control
          group,  while  the  blank  microneedle  group,  Sinapine  powder  plaster  group  and  ST-DMN  group  were  given  blank  microneedle,
          Sinapis  alba  powder (plaster,  1.5  g)  and  ST-DMN (3  tablets  at  2  acupoints)  at  same  acupoint,  once  a  day,  for  28  consecutive
                                                              days.  After  administration,  the  general  symptoms  were
