Methods:HLA-A,HLA-B genotyping was performed by polymerase chain reaction sequence-specific primer (PCR-SSP) in 119 preeclampsia patients,117 normal pregnant women and their neonates. Results:The study showed that 16 HLA-A and 39 HLA-B alleles were obtained in pre-eclamptic patients and normal pregnant women. 15 HLA-A and 37 HLA-B alleles were obtained in their neonates. No significant difference was found in maternal or neonatal HLA-A,HLA-B alleles between pre-eclampsia group and control group (P_(c)>0.05). The frequencies of HLA-A11,HLA-A24,HLA-B13,HLA-B14,HLA-B15,HLA-B52 maternal/fetus genetic assoications were significantly diffe-rent between pre-eclampsia group and control group (P<0.05). Conclusion:Some HLA-A,HLA-B maternal/fetus special bindings may be associated with the susceptibility or protective of pre-eclampsia.展开更多

文摘目的:通过不同类型的重度子前期(severe preeclampsia,S-PE)早产和自发早产的对比分析,探讨影响S-PE早产结局的相关因素。方法:将重度子前期(研究组)早产72例(早产儿83例),按不同孕周分为早期早产、中型早产及轻型早产3类,分别与相同类型的自发早产(对照组)222例(早产儿279例)进行孕产妇及围生儿结局对比分析。结果:研究组及对照组3类型间的早产儿病死率差异有显著性(P=0.000)。研究组与对照组同类型间早产儿病死率比较,差异无显著性(P>0.05);研究组早期早产儿平均出生体重明显低于对照组(P=0.003),而早产儿并发症发生率与对照组比较,差异无显著性(P>0.05);研究组中的中型早产新生儿除重度窒息明显高于对照组外(P=0.022),新生儿平均出生体重、新生儿轻度窒息率、新生儿病死率及新生儿加强护理NICU(neonatel intensive care unit,NICU)住院日和住院费两组间差异无显著性;在轻型早产组,除研究组NICU住院日明显长于对照组外(P=0.000),两组间其他观察指标的差异均无显著性。多元回归分析显示,早产的分娩孕龄是影响重度子前期早产儿死亡的主要因素;促胎肺成熟和孕期检查是影响新生儿病率的主要因素。结论:不论重度子前期早产还是自发早产,在早期早产阶段影响围生儿预后的主要因素是分娩孕龄,重度子前期早产与自发早产围生结局无明显差异。
