摘要
目的观察胎盘组织中血管内皮生长因子受体-1(VEGFR-1)、VEGFR-2、血浆中可溶性血管内皮生长因子受体-1(sVEGFR-1)及sVEGFR-2的表达水平,并探讨其在子癎前期的临床检测意义。方法ELISA检测正常妊娠期妇女和子癎前期患者血浆中的sVEGFR-1和sVEGFR-2的表达;RT-PCR检测正常妊娠期妇女和子癎前期患者胎盘中VEGFR-1、VEGFR-2、sVEGFR-1和sVEGFR-2mRNA的表达。结果ELISA检测结果显示,正常妊娠组分娩后较分娩前血浆中sVEGFR-1[(4.55±0.31)ng/mlvs(12.33±1.52)ng/m1]水平降低,子癎前期组分娩后血浆中sVEGFR.1[(8.13±0.74)ng/mlvs(77.25±9.47)ng/m1]水平亦降低,两组分娩前后数据变化比较差异有统计学意义(P〈0.01);正常妊娠组分娩前后血浆中sVEGFR-2分别为(8.74±1.24)ng/ml与(6.43±0.55)ng/ml,而子痫前期组分别为(5.69±0.75)ng/ml与(4.96±0.67)ng/ml;RT-PCR检测结果与其-致。结论子癎前期患者分娩后VEGFR-1血浆水平迅速下降,而VEGFR-2持续低水平表达,提示VEGFR-1可能与子癎前期发病率有关,而子癎前期患者血浆中VEGFR-2水平的降低可作为内皮功能障碍的标志。
Objective To analyze tissue vascular endothelial growth factor receptor 1 (VEGFR-1) and VEGFR-2 and their soluble form ( sVEFGR-1 and sVEGFR-2) in the plasma in patients with preeclampsia, and to explore its clinical significance. Methods sVEGFR-1 and sVEGFR-2 expressions in plasma of normal pregnancy women and preeclampsia patients were detected by enzyme-linked immunosorbnent assay (ELISA) ; VEGFR-1, VEGFR-2, sVEGFR-1 and sVEGFR-2 mRNA expressions of normal pregnancy women and preeclampsia patients in placenta were detected by reverse transcription-polymerase chain reaction (RT-PCR). Results ELISA results showed that the level of sVEGFR-1 in plasma of normal control group before and after delivery was ( 12. 33 ± 1.52) ng/ml and (4. 55 ± 0. 31 ) ng/ml, respectively, while that of preeclampsia group was ( 77. 25 ± 9.47 ) ng/ml and ( 8.13 ± 0. 74) ng/ml, respectively; the differences between before and after delivery in the two groups were of statistical significancel The level of sVEGFR 2 in plasma of normal control group before and after delivery was ( 8.74 ± 1.24 ) ng/ml and ( 6. 43 ± 0. 55 ) ng/ml, respectively, while that of preeclampsia group was ( 5.69 ± 0.75 ) ng/ml and (4. 96 ± 0. 67) ng/ml, respectively. RT-PCR results were consistent with ELISA results. Conclusions Rapid decrease of plasma sVEGFR-1 and continuously low-level expression of plasma sVEGFR-2 indicated that VEGFR-1 might be closely related to preeclampsia, and decrease of plasma sVEGFR-2 in preeclampsia women might be taken as a marker of endothelial cell function disorder.
