Relationship between serum trace elements and antioxidant capacity indexes in women of hypertensive disorder complicating pregnancy

摘要

Objective:To analyze the relationship between serum trace elements, antioxidant capacity index and hypertensive disorder complicating pregnancy (HDCP). Methods: Forty cases of normal healthy pregnant women, twenty-one pregnant women with high blood pressure, twenty-eight pregnant women with early stage of mild preeclampsia and twenty-two pregnant women with early stage of severe preeclampsia were selected respectively. Then, the differences of blood routine examination and blood coagulation function of the four groups were compared. At the same time, the levels of the serum trace elements and oxidative stress related indexes in the placental villi tissue were determined by flame atomic absorption spectrometry. Results:The white blood cells and hematocrit of HDCP pregnant women were significantly higher than those of normal healthy pregnant women;platelet and fibrinogen levels were obviously lower than those of normal healthy pregnant women, while thrombin time was shorter than that of normal healthy pregnant women;levels of serum copper, zinc and manganese were also significantly lower than whose of normal healthy pregnant women, while iron level was distinctly higher than that of normal healthy pregnant women. The differences between groups were statistically significant. The activities of SOD and GSH-PX in the placental villi tissue of HDCP pregnant women were significantly smaller than those of normal healthy pregnant women, while the Hcy level was higher than that of normal healthy pregnant women. The differences between groups were statistically significant. Conclusions:Pregnant women with HDCP has both imbalance of trace elements and redox system equilibrium, so we should strengthen the determination of the trace elements and redox related indexes of HDCP pregnant women to ensure health of maternal and child.
