摘　　要：目的探讨胰岛素样生长因子1(IGF-1)与胰岛素样生长因子结合蛋白1(IGFBP-1)在妊娠期高血压疾病发病中的作用。方法采用酶联免疫吸附法(ELISA)及免疫组化方法检测60例妊娠期高血压疾病患者(妊娠期高血压疾病组,其中妊娠期高血压20例、轻度子痫前期19例、重度子痫前期21例)及18例正常妊娠妇女(对照组)的血清及胎盘组织中IGF-1及IGFBP-1的水平,并分析妊娠期高血压疾病组患者血清中IGF-1水平与胎盘组织中IGFBP-1的相关性。结果(1)血清IGF-1水平:妊娠期高血压疾病组为(229±100)μg/L,明显低于对照组的(336±120)μg/L,两组比较,差异有统计学意义(P<0.01)。妊娠期高血压患者血清中IGF-1水平为(303±80)μg/L,轻度子痫前期患者为(233±77)μg/L,重度子痫前期患者为(155±73)μg/L。3者间比较,差异有统计学意义(P<0.05)。(2)胎盘组织中IGF-1阳性率:妊娠期高血压疾病组为48%(29/60),明显低于对照组的83%(15/18),两组比较,差异有统计学意义(P<0.01);轻、重度子痫前期患者明显低于对照组(P<0.05,P<0.01)。(3)血清中IGFBP-1水平:妊娠期高血压疾病组为(161±90)μg/L,明显高于对照组的(98±75)μg/L,两组比较,差异有统计学意义(P<0.01)。妊娠期高血压患者为(97±73)μg/L,轻度子痫前期患者为(157±69)μg/L,重度子痫前期患者为(225±81)μg/L。3者间比较,差异有统计学意义(P<0.05)。(4)胎盘组织中IGFBP-1阳性率:妊娠期高血压疾病组为77%(46/60),明显高于对照组的39%(5/18),两组比较,差异有统计学意义(P<0.01);轻、重度子痫前期患者明显高于对照组(P<0.05,P<0.01)。(5)相关性:妊娠期高血压疾病组患者血清及胎盘组织中IGF-1水平分别与相应部位的IGFBP-1水平均呈负相关(r=-0.269,P<0.05;r=-0.396,P<0.01)。血清中IGFBP-1水平与胎盘组织中IGFBP-1表达水平呈正相关(r=0.388,P<0.01)。结论孕妇血清及胎盘组织中IGF-1、IGFBP-1水平变化与妊娠期高血压疾病发病及病�Objective To investigate the role of insulin like growth factor-1 （ IGF-1 ） and insulin like growth factor binding protein-1 （ IGFBP-1 ） in the pathogenesis of hypertensive disorder complicating pregnancy. Methods The levels of IGF-1 and IGFBP-1 in serum and placenta were detected from 60 patients with hypertensive disorder complicating pregnancy （hypertensive disorder complicating pregnancy group） and 18 normal pregnant women（ control group） by enzyme linked immunosorbent assay （ELISA） and immunohistochemistry. Results （ 1 ） Serum level of IGF-1 （229 ±100 ）μg/L in hypertensive disorder complicating pregnancy group was significantly lower than that in control group （ 336 ±120 ） μg/L, （ P 〈0. 01）. There were significant differences among gestational hypertension （303 ± 80 ） μg/L, mild preeclampsia（233 ±77 ） μg/L and severe preeclampsia groups （ 155 ±73 ） μg/L, （ P 〈 0.05 ） . （ 2 ） The expression of IGF-1 in the placenta of hypertensive disorder complicating pregnancy group （48% , 29/60） was significantly reduced than that in control group （83%, 15/18 ;P 〈0. 01 ）. Its expressions in mild and severe preeclampsia patients were lower than that in control group （ P 〈 0. 05,P 〈 0. 01 ）. （3） Serum IGFBP-1 from hypertensive disorder complicating pregnancy group （ 161±90 ） μg/L was significantly higher than that in control group （ 98±75 ） μ/L, （ P 〈 0. 01 ） . There were significant differences among gestational hypertension（97 ± 73 ）μg/L, mild preeclampsia（ 157 ± 69 ） μg/L and severe preeclampsia groups （ 225 ±81 ）μg/L（P 〈 0. 05 ）. （4）The expression of IGFBP-1 in hypertensive disorder complicating pregnancy group （ 77 %, 46/60） was higher than that in control group （ 39 % ,5/18 ）, （ P 〈 0. 01 ）. Its expression in mild and severe preeclampsia patients were higher than that in control group （P 〈0. 05 ）. （5） The levels of IGF-1 in serum and placenta had a significant
