孕妇血清锌浓度与稽留流产关系研究

目的研究孕妇血清锌浓度在孕早期的变化情况，探讨孕妇血清锌浓度与稽留流产的关系。方法2007年6月至2008年6月采用原子光谱吸收法对笔者所在医院64例稽留流产孕妇和66例正常对照孕妇早孕的血清锌浓度进行检测。观察对照组各孕周血锌浓度变化情况，对比对照组和研究组血锌浓度。结果孕妇血清锌浓度在孕早期呈逐渐下降趋势，但其变化不显著（P〉0．05）。研究组孕妇血清锌浓度明显低于对照组（P〈0．05）。结论孕妇血清锌浓度对维持正常妊娠有重要作用，血锌浓度低可能会导致稽留流产。

Research of the relation between Maternal serum zinc concentration and missed abortion

Objective To study the change of serum zinc concentration of pregnant women at early pregnancy and to explore the relation between Maternal serum zinc concentration and missed abortion. Methods Maternal serum zinc concentration of 64 cases pregnancy women with missed abortion and 66 cases of normal pregnant women in early pregnancy between June 2007 and June 2008 was tested by atomic absorption spectrometry in our hospital. The change of serum zinc concentration of different pregnancy weeks was observed and the concentration between study group and control group was compared. Results The serum zinc concentration of pregnant women at early pregnancy showed a gradnal downward trend, hut the change was not significant （ P 〉 0.05 ） ; maternal serum zinc concentration of study group was significantly lower than the control group （ P 〈 0.05 ）. Conclusion The maternal serum zinc concentration in normal pregnancy play an important role in maintaining pregnancy. Low serum zinc concentration may cause missed abortion.
