妊娠期高血压疾病对新生儿血脂的影响

目的 探讨妊娠期高血压疾病(PIH)对新生儿血脂的影响.方法 PIH母儿80例,按第6版妇产科学PIH诊断标准分为3组:妊娠期高血压疾病组30例、子痫前期轻度组30例、子痫前期重度组20例,另设同期正常对照组40名,采用全自动生化分析仪测定脐血甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、ApoA及脂蛋白(LPA).结果 (1)妊娠期高血压疾病组、子痫前期轻度组、子痫前期重度组、正常对照组新生儿脐血TG的浓度分别为(0.25±0.10)、(0.33±0.09)、(0.39±0.06)、(0.23±0.07)mmol/L,妊娠期高血压疾病各组TG水平均高于正常对照组,且随母亲妊娠期高血压程度的加重呈进行性的升高,组间比较差异有统计学意义(F=2.765,P<0.05).(2)妊娠期高血压疾病组、子痫前期轻度组、子痫前期重度组、正常对照组新生儿脐血HDL-C的浓度分别为(0.61±0.23)、(0.54±0.25)、(0.47±0.15)、(0.65±0.14)mmol/L;ApoA的浓度分别为(0.63±0.24)、(0.59±0.16)、(0.53 ±0.21)、(0.69±0.12)g/L,妊娠期高血压疾病各组新生儿脐血HDL-C、ApoA均低于正常对照组,且随母亲妊娠期高血压程度的加重呈进行性的降低,组间比较差异有统计学意义(F=2.783,P<0.05;F=2.831,JP<0.05).(3)妊娠期高血压疾病组、子痫前期轻度组、子痫前期重度组、正常对照组新生儿脐血TC的浓度分别为(1.41±0.37)、(1.51±0.45)、(1.56±0.56)、(1.36±0.41)mmol/L;LDL-C的浓度分别为(0.79 ±0.26)、(0.80 ±0.18)、(0.82±0.30)、(0.74±0.18)mmol/L,妊娠期高血压疾病各组新生儿脐血TC、LDL-C均高于正常对照组,且随母亲妊娠期高血压程度的加重呈进行性升高,组间比较差异无统计学意义(F=0.695,P>0.05;F=0.483,P>0.05).(4)子痫前期轻度组、子痫前期重度组新生儿脐血LPA分别为(24.50±12.01)g/L与(22.68±9.50)g/L,低于正常对照组(25.70±11.90)g/L,妊娠期高血压组新生儿脐血LPA(33.46±20.10)g/L高于正常对照组,且妊娠期高血压疾病各组新生儿脐血LPA随母亲妊娠期高血压疾病程度的加重呈进行性降低,但组间比较差异无统计学意义(F=1.480,P>0.05).结论 妊娠期高血压疾病时官内的不良环境使胎儿脂代谢发生改变,且随母亲妊娠期高血压程度的加重,这种改变越重,推测妊娠期高血压组母儿以后可能发生冠心病、动脉粥样硬化与脂代谢相关性疾病的危险性较正常对照组有可能增加.

Abstract：

Objective To investigate the effect of pregnancy-induced hypertension (PIH) syndrome on the blood lipid level of neonate. Methods Eighty neonates, whose mother had PIH, were enrolled and divided into three groups according to the 6th version of diagnostic standard from published Obstetrics and Gynecology:gestational hypertension group (PIH group 1 ,n = 30) ,mild pre-eclampsia group (PIH group 2,n =30),serious pre-eclampsia group (PIH group 3,n =20) ,and 40 infants with healthy mother were enrolled as normal control group. The blood lipid was measured by automatic biochemical analyzer. Results (1) The TG levels of the cord blood were (0.28±0. 10)mmol/L in PIH group 1,(0.33 ±0.09)mmol/L in PIH group 2,(0.39 ±0.06) mmol/L in PIH group 3,and (0. 23 ±0. 07)mmol/L in normal control respectively. TG levels were significantly higher in PIH groups compared to normal control,and the TG concentration increased gradually with the mothers' gestational hypertension (F = 2. 765, Ps <0. 05). (2)The HDL-C levels of the cord blood were (0. 61 ±0. 23) mmol/L in PIH group 1, (0. 54 ± 0. 25) mmol/L in PIH group 2, (0.47 ± 0. 15) mmol/L in PIH group 3, (0. 65 ±0. 14) mmol/L in the normal contral respectively;and the ApoA levels of the cord blood were (0. 63 ±0.24)g/L in PIH group 1 ,(0. 59 ±0. 16)g/L in PIH group 2, (0.53 ±0.21)g/L in PIH group 3,(0.69 ±0. 12)g/L in the normal contral respectively. Both index were significantly higher in PIH groups compared to normal control, and the concentrations decreased gradually with the mothers' gestational hypertension (F=2.783,P<0.05;F=2.831,P<0.05). (3)The TC levels of the cord blood were (1.41 ± 0. 37) mmol/L in PIH group 1, (1. 51 ±0.45) mmol/L in PIH group 2, (1. 56 ±0. 56) mmol/L in PIH group3, (1. 36 ±0.41) mmol/L in the normal contral respectively;and the LDL-C levels of the cord blood were (0. 79 ±0. 26)mmol/L in PIH group 1,(0. 80 ±0. 18)mmol/L in PIH group 2,(0. 82 ±0. 30)mmol/L in PIH group 3,(0.74 ±0. 18) mmol/L in the normal contral respectively. The data showed that the cord blood TC and LDL-C levels of PIH were higher than normal control and increased gradually with the mothers'gestational hypertension, but they didn' treach the significant level (F = 0. 695,P>0. 05;F = 0. 483,P>0. 05). (4)The LPA levels of the cord blood were (24. 50 ± 12. 01) g/L in PIH group 2, (22. 68 ± 9. 50) g/L PIH group 3,which were lower than normal control (25.70 ±11.90) g/L, and the LPA levels of the cord blood were higher in PIH group 1(33.46 ± 20. 10)g/L,while the differences didn't reach significant level compared among four groups (F = 1.480,P> 0.05). Conclusion The unhealthy intrauterus condition of PIH lead abmoral fat metabolism in fetus, and itmight get worse along with the severity of the mother's gestational hypertension. We presumed that the neonates of PIH mothers would be more prone to have coronary heart disease,atherosclerosis and abnormal fat metabolism related disease compared with newboms from normal control group.
