摘 要: | 目的 观察桃红四物汤对产后血瘀大鼠子宫修复的促进作用,探讨其与内皮素-1(endothelin-1,ET-1)、诱导型一氧化氮合酶(inducible nitric oxide synthase,iNOS)及血管内皮生长因子(vascular endothelial growth factor,VEGF)和血管内皮生长因子受体2(vascular endothelial growth factor receptor 2,VEGFR-2)的关联性。方法 选取产后血瘀模型复制成功的大鼠40只,将其随机分为桃红四物汤高剂量(18.0 g/kg)、中剂量(9.0 g/kg)、低剂量(4.5 g/kg)组,阳性对照组(益母草颗粒4.3 g/kg)和模型组(蒸馏水),另取正常雌性大鼠作为正常对照组。连续给药7 d后,腹主动脉取血,分离子宫,苏木精-伊红染色法观察子宫血瘀状态,免疫组织化学法检测子宫VEGFR-2表达情况;酶联免疫吸附法检测血清中ET-1、iNOS及VEGF水平。结果 桃红四物汤可明显改善子宫血瘀程度,促进子宫组织中VEGFR-2的表达;桃红四物汤高、中剂量组大鼠血清VEGF及iNOS水平明显升高(P<0.05),ET-1水平明显降低(P<0.05)。结论 桃红四物汤可促进产后血瘀大鼠子宫修复,其修复作用可能与调节子宫血管舒缩功能及促进子宫血管新生有关。

Abstract: | Objective To observe the efficacy of Taohong Siwu Decoction in promoting uterine repair in rats with postpartum blood stasis, and to investigate its effects on endothelin-1 (ET-1), inducible nitric oxide synthase (iNOS), vascular endothelial growth factor (VEGF), and vascular endothelial growth factor receptor 2 (VEGFR-2). Methods Forty rats in which a model of postpartum blood stasis was successfully established were randomly divided into high-, middle-, and low-dose Taohong Siwu groups (18.0 g/kg, 9.0 g/kg, and 4.5 g/kg), positive control group (Herba Leonuri Granule 4.3 g/kg), and model group (distilled water); normal female rats were selected as normal control group. All rats received respective treatments for 7 consecutive days. Blood was collected from the abdominal aorta, and the uterus was isolated. HE staining was used to evaluate blood stasis in the uterus. The expression of VEGFR-2 in the uterus was measured by immunohistochemistry. Serum levels of ET-1, iNOS, and VEGF were determined by ELISA. Results Taohong Siwu Decoction significantly relieved blood stasis in the uterus and increased the expression of VEGFR-2 in the uterus. The high- and middle-dose Taohong Siwu Decoction groups had significantly increased serum levels of VEGF and iNOS (P<0.05) and a significantly reduced serum level of ET-1 (P<0.05). Conclusion Taohong Siwu Decoction can promote uterine repair in rats with postpartum blood stasis, possibly by regulating uterine vasomotion and promoting uterine angiogenesis. |
