It is reported ' Reporter Wang Dan) Only need to draw 2 ml from pregnant woman's body - amniotic fluid of 5 ml, does not need to train outside the body, can diagnose foetus' chromosome disease unusual in number within 24 hours - 48 hours. Recently, taken the lead by subsidiary Beijing Gynecological and Obstetric Hospital of Capital University of Medical Sciences, diagnose what the centre participated in before 55 family properties of the whole country " The fluoro hybridizes the application study of technology in antenatal genetic disease is monitored in situ " Confirm through Ministry of Public Health, indicate the fast pre-natal diagnosis technology system of our country is built up formally. Clinical statistics reveal, 70% of the inborn defects are caused by inherent cause. Sift checking it is a main route to reduce morbidity before production. The reproduction hereditary head of the department Professor Wang ShuYu of Gynecological and Obstetric Hospital in Beijing introduces, it is DNA probe which adopts the fluorogenic mark that the fluoro hybridizes technology in situ, and is measured the complementarity of DNA array in the sample according to the probe, to have pathologic 5 kinds of chromosome of meaning most at the clinic ' Namely the 13th, the 18th, the 21st, X and Y chromosome) The unusual most common chromosome disease that causes of the number is measured. For example, when three body situations took place in the chromosome to measure until the 21sting, can diagnose as Tang's' syndrome. It is reported, this research is undertaken by the scientific and technological research and development centre of the medical and health of Ministry of Public Health, finish, study 5558 of case in the whole country already, success rate and diagnose, lead, have obvious difference with traditional the intersection of cell and science of heredity correctly, and detection time is shortened greatly. Chaining In September 12 " China prevents on the day of inborn defect " . Statistics reveal, about 23 million people of annual pregnant woman's colony of our country, the neonatal quantity is about 20 million every year, the inborn defect infant accounts for 4% of new born population- 6%
