Results The mortality and respiratory distress syndrome occurrence of the perinatal neonate<34.weeks(20.8%,15.6%)were obviously higher than that of perinatal neonate≥34 weeks (1.9%,1.3%).

During ontogeny, expression of these genes undergoes two developmental switches, from embryonic (ε) to fetal (Gγ and Aγ) during the early gestational period and from fetal to adult (δ and β) during the perinatal period.
This thesis selected lactulose as substitute for antibiotic, influence of immunity&fecal bacterial flora of lactulose on calves in perinatal period has been researched, the effect of lactulose in milk for calves' health and growth function has been appraised.
Methods The 13 autopsy cases died in perinatal stage and 1 survived clinical case diagnosed AFE in recent 10 years were studied using HE staining, porphobilin staining , mucus staining and immuohistochemistry staining.
Although apoptosis is believed to play an important role in the ontogenetic development of animals, the molecular mechanism that triggers the regression of liver hemopoiesis during the perinatal period is not known.
Since hepatic γ-glutamyl transferase (GT) levels change markedly during the perinatal period in rodents, the metabolism of glutathione (GSH), a naturally occurring major antioxidant, might change significantly in and around liver cells.
On the basis of observations of 131 autopsies on newborn babies, we found that pulmonary affections and intrauterine asphyxia were the two most common causes of death with major malformations ranking next and intracranial hemorrhage the third. Prematurity constituted 51% of the uncorrected perinatal mortality under study. It was felt that death in these babies were due to incomplete development of vital organs especially of lungs resulting in anoxia or interference with circulation. In order to profit...
The average perinatal mortality rate in seven maternal hospitals in Shanghai in 1977 was 14.18‰ with the highest rate of 19.58‰ and the lowest rate of 8.06‰. Congenital anomalies, hypoxia, disorders of the umbilical cord and placenta, and prematurity and macerated fetuses were the chief causes of death. The improvement of obstetrical techniques, the prompt unification of the definition and standardization of perinatal parameters and terms, and the establishment of the centers of modern intensive...
41 cases of pregnancy complicated by diabetes mellitus were treated in the periodJanuary 1953-July 1979.According to White's classification,there were 23 cases of classA,17 of class B and 1 of Class D.The percentage of toxemia in this series was 68.3%,of macrosomia 41.5% and polyhydramnios 17.1%.There were 11 perinatal deaths witha mortality rate of 26.8%,but no maternal death.Prenatal diagnosis is very importantin reducing the perinatal mortality rate.In the class A,there were 8 fetal losses wi...
