孕妇血清锌浓度与早期先兆流产关系研究

Research to the Relations between Maternal serum zinc concentration and early threatened abortion

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早期先兆流产的关系。方法 2007年6月至2008年6月采用原子光谱吸收法对我院62例早期先兆流产孕妇和66例正常对照孕妇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在正常妊娠维持中起重要作用,血锌浓度低可能会导致早期先兆流产。

Objective ： To study the Change of serum zinc concentration of pregnant women at early pregnancy and to explore the Relations between Maternal serum zinc concentration and early threatened abortion. Methods ： Maternal serum zinc concentration of 62 cases pregnancy woman with early threatened abortion and 66 cases of normal pregnant women in early pregnanacy between June 2007 and June 2008 was tested by atomic absorption spectrometry in our hospital. The change of serum zinc concentration of different preg- nancy weeks was observed and the concentration between study group and control group was compared. Results： The serum zinc con- centration of pregnant women at early pregnancy showed a gradual downward trend, but 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 pregnanaey, low serum zinc concentration may cause early threatened abortion.
