          摘   要  目的  基于Notch1信号通路探讨姜黄素对子宫内膜异位症(EMS)模型大鼠的影响及机制。方法  在动情周期趋于一致
          的雌性SD大鼠腹壁上种植自体子宫内膜,构建EMS模型,并将其随机分为模型组,姜黄素低、中、高剂量组(60、120、240 mg/kg)
          和Notch1抑制剂DAPT组(7 mg/kg),另设假手术组,每组10只。各组大鼠灌胃或尾静脉注射相应药物,给药4周后,分别通过超
          声仪和肉眼观察、测量子宫内膜异位病灶并计算体积;观察病灶组织病理形态;检测大鼠腹腔液中白细胞介素1β(IL-1β)、IL-6和
          肿瘤坏死因子α(TNF-α)含量,以及子宫内膜异位病灶中Notch1、基质金属蛋白酶9(MMP-9)和血管内皮生长因子(VEGF)mRNA
          和蛋白表达水平。结果  与模型组比较,姜黄素低、中、高剂量组和DAPT组大鼠子宫内膜异位病灶的体积均显著减小(P<0.05),
          柱状上皮萎缩或消失,囊泡消失;腹腔液中 IL-1β、IL-6 和 TNF-α(姜黄素低剂量组除外)水平以及子宫内膜异位病灶中 Notch1、
          MMP-9和VEGF mRNA(姜黄素低剂量组MMP-9、VEGF除外)及蛋白(姜黄素低剂量组MMP-9除外)表达水平均显著降低(P<
          0.05),其中姜黄素高剂量组和DAPT组大部分指标优于姜黄素低、中剂量组。结论  姜黄素对EMS具有改善作用,其作用机制可
          能与抑制Notch1信号通路、减轻局部炎症反应、抑制异位内膜的侵袭和血管生成有关。

          ABSTRACT    OBJECTIVE  To  explore  the  impact  and  mechanism  of  curcumin  on  endometriosis (EMS)  model  rats  based  on
          Notch1  signaling  pathway.  METHODS  Female  SD  rats  with  synchronized  estrous  cycles  were  implanted  with  autologous
          endometrium on the abdominal wall to construct EMS  model. EMS  rats were randomly divided into model group, low-, medium-
          and high-dose groups of curcumin (60, 120, 240 mg/kg), and Notch 1 inhibitor DAPT group (7 mg/kg). The sham surgery group
          was also established, with 10 rats in each group. Rats in each group received intragastric administration or injection via caudal veins
          with  the  corresponding  drugs  for  4  weeks.  Endometriotic  lesions  were  observed  and  measured  using  ultrasound  and  visual
          inspection,  and  their  volumes  were  calculated.  Histopathological  morphology  of  the  lesion  tissues  was  observed.  The  levels  of
          interleukin-1β (IL-1β),  IL-6,  and  tumor  necrosis  factor-α (TNF-α)  in  the  abdominal  cavity  fluid,  as  well  as  the  mRNA  and
          protein  expression  levels  of  Notch1,  matrix  metalloproteinase-9 (MMP-9),  and  vascular  endothelial  growth  factor (VEGF)  in  the
          endometriotic  lesions  were  measured.  RESULTS  Compared  with  the  model  group,  the  volume  of  endometriotic  lesions  in  the
          low- ,  medium-  and  high-dose  groups  of  curcumin  and  the  DAPT  group  was  significantly  decreased (P<0.05);  atrophy  or
          disappearance  of  columnar  epithelium,  cyst  disappearance;  the  levels  of  IL-1β,  IL-6,  and  TNF- α (except  for  the  low-dose
          curcumin  group)  in  the  abdominal  cavity  fluid,  as  well  as  the  mRNA (except  for  MMP-9  and  VEGF  in  the  low-dose  curcumin
          group)  and  protein (except  for  MMP-9  in  the  low-dose  curcumin  group)  expression  levels  of  Notch1,  MMP-9,  and VEGF  in  the
          endometriotic  lesions  were  significantly  decreased (P<0.05).  The  curcumin  high-dose  group  and  DAPT  group  showed  superior
          results  in  most  indicators  compared  to  the  curcumin  low-  and  medium-dose  groups.  CONCLUSIONS  Curcumin  has  an  improving
                                                              effect on EMS, and its mechanism may be related to inhibiting
