Objective To evaluate the clinical value and effectiveness of ultrasound screening for fetal chromosomal abnormalitie in the middle and late pregnancy. Methods Fetuses who were detected with abnormal ultrasound findings during the middle and late pregnancy, and high risk of maternal serum screening underwent amnioeentesis or eordocentesis for fetal chromosome karyotypes. Results (1) A total of 31 cases with fetal malformation diagnosed by ultrasound were analysed for fetal chromosome karyotypes, and 8 (25.8%) cases were proved with fetal abnormal chromosome karyotypes. There were 3 cases of cervical springwater cyst accompany with edema,and all were fetal abnormal chromosome karyotypes. There were 3 cases of cervical pachyderma,and 2 were fetal abnormal chromosome karyotypes. There was one case with multiple malformations, one with Dandy-Walker malformation and one with holoprosencephaly malformation,all were revealed fetal abnormal chromosome karyotypes. (2) A total of 516 cases with high risk of Down's syndrome and trisomy 18 by maternal serum screening were analysed for fetal chromosome karyotypes,and 14(2.710%) cases were proved with fetal abnormal chromosome karyotypes, which include 7 cases of Down's syndrome and 7 cases of other fetal abnormal chromosome karyotypes. (3) A total of 544 (516 + 28)cases with high risk by the combination of ultrasound and maternal serum screening were analysed for fetal chromosome karyotypes, and 21 (3.86%) cases were proved with fetal abnormal chromosome karyotypes, the rate of detection higher than only maternal serum screening 42.43%.Conclusions Fetal structure abnormalities were the effective ultrasound signs for fetus chromosomal abnormalities screening in the middle and late pregnancy. The combination of ultrasound and maternal serum screening can improve the rate of fetus chromosomal abnormalities screening and be an effective way to retrieve false-positive and lower risk of maternal serum screening.

Objective To investigate the effect of progressive neurological deterioration ( PND) of cerebral watershed infarction on early prognosis. Methods The consecutive patients with cerebral watershed infarction admitted in the Department of Neurology,Jinling Hospital,Nanjing University School of Medicine and their cerebral watershed infarctions confirmed by the imaging examination from March 2009 to March 2014 were enrolled. The clinical features, laboratory indicators and imaging features of internal watershed infarction,cortical-type watershed infarction,and mixed watershed infarction were identified and analyzed. The National Institutes of Health Stroke Scale was used to score neurological deficit. The modified Rankin scale ( mRS) was used to score the prognosis of patients. Single factor analysis was used to compare the differences between the groups. At the same time,the correlation between PND and poor prognosis of cerebral watershed infarction at day 90 was analyzed by multivariable Logistic regression analysis. Results A total of 89 patients with cerebral watershed infarction were enrolled,including 43 cortical-type watershed infarctions,36 internal watershed infarctions, and 10 mixed watershed infarctions. Single factor analysis indicated that the incidences of PND of internal watershed infarction and mixed watershed infarction were significantly higher than the cortical-type watershed infarction (36. 1% [n=13],50. 0% [n=5], and 16. 3% [n=7],respectively;P=0. 018). At day 90,28 patients had poor prognosis,and mRS was (3.4±1. 0) scores at day 90. There was significant difference in the types of infarction between the patients with poor prognosis and patients with good prognosis (P<0. 05). In patients with poor prognosis, most of them were internal watershed infarctions,accounting for 50. 0% (14/28),while in patients with good prognosis,most of them were cortical-type watershed infarctions(57. 4% [35/61]). The incidence of PND in patients with poor prognosis was significantly higher than that in patients with good prognosis (57.1% [16/28] vs. 14. 8% [9/61];P<0. 05). The result of multivariate Logistic regression analysis showed that after adjustment for confounding factor, PND was independently associated with the poor prognosis of cerebral watershed infarction at day 90 (OR 6. 969,95%CI 2. 451-19. 869;P<0. 01). Conclusion Compared with the cortical-type watershed infarction, the patients with internal watershed infarction is more prone to have PND, and PND is independently correlate with the poor prognosis at day 90.
