【摘要】 目的研究复方丹参注射液对人羊膜上皮细胞(human amniotic epithelial cells,hAECs)水通道蛋白3(aquaporin 3,AQP3)表达的影响,探讨复方丹参注射液治疗羊水量过少的机制。方法选取无并发症的8例羊水过少和8名羊水量正常的足月产妇的hAECs进行原代培养,采用RT-PCR和免疫印迹Western blot技术,检测复方丹参注射液不同浓度(0.000、0.001、0.010、0.020、0.060、0.100mg/mL)、不同作用时间(0、6、12、24、48h)作用前后,两组hAECs中AQP3 mRNA和蛋白的表达。结果 (1)羊水过少组hAECs中AQP3的表达较羊水正常组下调(P<0.05)。(2)复方丹参注射液浓度为0.010mg/mL时,两组hAECs中AQP3的表达均达到峰值,与其他浓度作用结果比较,差异有统计学意义(P<0.05)。(3)0.010mg/mL浓度的复方丹参注射液作用12h,两组hAECs中AQP3的表达均达到峰值,与其他作用时间比较,差异有统计学意义(P<0.05)。(4)0.010mg/mL浓度的复方丹参注射液作用12h后,两组hAECs中AQP3的表达均上调,但羊水过少组中AQP3的表达上调较羊水正常组明显(P<0.05)。结论复方丹参注射液可调节hAECs中AQP3的表达,羊水过少时复方丹参注射液对hAECs中AQP3表达的调节作用更加明显。更多还原

【Abstract】 Objective To study the effects of Compound Salvia miltiorrhiza Injection (CSI)on aquaporin 3 (AQP3)expression in human amniotic epithelial cells (hAECs), and to explore its mechanisms for treating oligohydramnios. Methods The hAECs selected from 8 human term pregnancies with oligohydramnios and no other complications (as the test group)and 8 human term pregnancies with normal amniotic fluid volume (as the control group)were primarily cultured. The mRNA and protein expressions of AQP3 in hAECs were detected using reverse transcription-polymerase chain reaction and Western blot with various concentrations of CSI (0.000, 0.001, 0.010, 0.020, 0.060, and 0.100 mg/mL, respectively)at different time points (0, 6, 12, 24, and 48 h, respectively). Results (1)Compared with the control group, the AQP3 expression was down-regulated in the test group (P <0.05). (2)The AQP3 expression in the two groups reached the peak when the concentration of CSI was 0.010 mg/mL, showing statistical difference when compared with other concentrations (P <0.05). (3)The AQP3 expression reached the peak when 0.010 mg/mL CSI acted for 12 h, showing statistical difference when compared with other concentrations (P <0.05). (4)The AQP3 expression was up-regulated in the two groups when 0.010 mg/mL CSI acted for 12 h. But the up-regulated AQP3 expression was more obvious in the test group than in the control group (P <0.05). Conclusions CSI could regulate the AQP3 expression in hAECs. CSI showed more obvious effects on the AQP3 expression in hAECs of oligohydramnios human term pregnancies.更多还原
