冼夫人文化在地方高校传承和发展状况研究

以好心精神为核心的冼夫人文化作为粤西地区的特色文化,与当代社会主义核心价值观相契合。它对大学生进行爱国主义教育、提高人文素质、树立正确的价值观方面有重要的引导作用。以粤西4所高校为例,通过发放问卷的形式对冼夫人文化在高校大学生中的影响进行调查,指出了冼夫人文化在高校传承中存在的问题,并深入了分析在高校思想政治教育工作中如何融入冼夫人文化。     

The outcome of pregnancy and prenatal chromosomal diagnosis of fetuses in couples including a translocation carrier

In order to evaluate the relation between chromosomal translocation and the outcome of pregnancy, 50 couples were examined. Subjects consisted of 35 couples that included a reciprocal translocation carrier; 13 included a Robertsonian translocation carrier and 2 included a carrier of a mosaic reciprocal translocation. The reasons for performing chromosomal examinations were mainly infertility and abnormality of neonates. The rates of miscarriages and neonatal abnormalities in prior pregnancies were significantly higher than the birth rate of morphologically normal newborns. The presence of a translocation is closely related to reproductive failure because of the chromosomal imbalance. However, prenatal chromosomal examination after the 15th gestational week in subsequent pregnancies revealed that almost half of the fetuses showed normal karyotypes and only 12.8 per cent of the fetuses showed a chromosomal imbalance. Many chromosomally imbalanced fetuses are spontaneously aborted before amniocentesis. The risk of chromosomal imbalance is relatively low in prenatal diagnosis, but partial trisomies of small rearrangements tend to be preserved.
