摘要
目的
2
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
2
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
2
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
2
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
2
To explore the impact and mechanism of curcumin on endometriosis （EMS） model rats based on Notch1 signaling pathway.
METHODS
2
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
2
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
2
Curcumin has an improving effect on EMS， and its mechanism may be related to inhibiting Notch1 signaling pathway， reducting local inflammatory responses， and inhibiting ectopic endometrial invasion and angiogenesis.
