Abstract:Objective: To explore the change and clinical significance of serum markers in Down syndrome (Down syndrome,DS) prenatal screening. Methods: The selection from July 2014 to July 2017 in our hospital during the application of quantitative mass spectrometry was used to detect 2598 cases of 14+1~21+6weeks pregnant women were detected serum AFP、uE3、HCG and InhA markers and content, combined with maternal age, body mass, gestational weeks, single twins, smoking history, whether patients with diabetes, previous factors without abnormal pregnancy history, the use of Teng cheng version of the system risk assessment. Results: The 2598 cases of pregnant women, screening out the abnormal chromosome 117 cases of pregnant women with high risk pregnancy, including 54 cases of pregnant women were amniocentesis antenatal examination, diagnosis of Down syndrome in 21 cases, 2 cases of trisomy 18-syndrome, 3 cases of other fetal chromosomal abnormalities. (1) The levels of AFP and uE3 were lower than that in the low-risk group, [(15.54±1.23)vs.(35.38±3.54) ng/mL] and [(4.16±3.25)vs.(8.31±2.26) ng/mL] , respectively. the difference was significant (P<0.05). The levels of HCG and InhA were higher than that that in the low risk group, [(2.94±1.26)vs.(1.16±3.12) mIU/mL] and [(2.94±1.26)vs.(1.16±3.12) mIU/mL], respectively.(2) The total positive rate of screening for birth defects in the >35-year-old pregnant women (10.08%) was higher in ≤35-year-old pregnant women (3.50%), the difference was significant (P<0.05). (3) The total positive rate of diagnosis of birth defects in high-risk group (65.22%) was significantly higher than that in the low-risk pregnant women (35.48%), the difference was significant (P<0.05). (4) The levels of serum HCG and InhA rise while The levels of serum AFP and InhA reduced in the pregnant women of pregnancy DS fetal. Conclusions: The second trimester serum marker examination can be used as an important index prediction of fetal chromosomal abnormalities, and take effective measures in a timely manner through the prenatal diagnosis, can significantly reduce the birth defects, to help students work.
