Yangpu District has kicked off a project which offers free Down’s screening for 4,000 pregnant women in the district, with Xinhua Hospital as the designated hospital.
As learned from the launching ceremony, the project aims at pregnant women aged under 35 and have registered the pregnancy record in Yangpu. Starting from this year, qualified pregnant women will be informed when they report their pregnancy to community health service centers. Those who are willing to take part in the Down’s screening will be registered and get reservation materials and instructed to go to the Prenatal Diagnosis Center of Xinhua Hospital to take type-B ultrasonic inspection and serology screening. The Prenatal Diagnosis Center will complete the screening and be responsible for follow-up clinic treatment.
The incident rate of “Down’s infants” is around 1/700 in Yangpu. About 5-6% of the pregnant women that receive the Down’s screening are diagnosed to have “High Risks” and need to receive amniocentesis or non-invasive prenatal gene test to make sure whether the chromosomes of the fetuses are abnormal.
Down’s syndrome is also called Trisomy 21 Syndrome. A person has 23 pairs of chromosomes, 46 in total. No.21 chromosome has changed from two to three, which causes a series of syndromes to the children. The most obvious syndrome is the child being slow and retard. “Even though the chromosome diseases are related to heredity, the morbidity is mostly caused by objective factors. For example, the pregnant women are in contact with some poisonous and hazardous substances before pregnancy; the pregnant women are of advanced maternal age; there is interior decoration in the house of the pregnant women; the pregnant women are engaged in shoes making or working in a hairdressing salon,” said the expert.
