Objective To analyze the correlation between the blood typing test,irregular antibodies screening of pregnant women and hemolytic disease of newborn(HDN).Methods The ABO blood type and Rh(D)blood type of pregnant women were detected,and the irregular antibodies of pregnant women were screened.The blood type serol-ogy and hemolytic disease were detected in neonates with jaundice.Results In specimens of 2 032 pregnant women with type O blood,their husbands were non -O blood type,after delivery,152 neonates were diagnosed as HDN. Among 2 032 pregnant women with type non -O blood,only 5 neonates were diagnosed as HDN.There was significant difference between the two groups (χ2 =135.4,P <0.01).27 pregnant women with RhD negative type,their hus-bands were RhD positive,after delivery,4 neonates were diagnosed as HDN.Conclusion Pregnant women's blood type and irregular antibody are closely related to neonatal hemolysis disease.So pregnant women's blood type and irregular antibody should be regular project in pregnancy,and so as to prevent neonatal hemolytic anemia caused by blood type of feto -maternal incompatibility.

The oocyte cryopreservation is more promising than embryo freezing in clinical applications,preservation of female fertility,legal and ethical aspects in this decade.The redundant oocytes retrievedfrom ⅣF cycles can potentially donate oocytes,which have unique advantages in economy and feasibili-ty.We have achieved success in embryo freezing,but just obtained poorer results in oocyte cryopreserva-tion which was mainly because of the low rates of survival,fertilization,and cleavage.The character ofthe plasma membrane and the time of cortical granules present at the metaphase of meiosis Ⅱ with thespindle system consist of the major difference between oocytes and embryos.Moreover,the oocytes shouldbe fertilized by sperm at the appropriate time.We used a refined slow freezing method to improve the sur-vival rate and increased sucrose concentration to dehydrate oocytes.Vitrification was another approach toprevent harms.Besides,intracytoplasmic sperm injection was used to overcome possible zona hardeningafter the release of cortical granules.Oocytes after cryopreservation showed serious disturbances of the mi-crotubules immediately after thawing as they were vulnerable to the thermal changes and easy to depoly-merize.Fertilization of these oocytes with disorganized spindles led to chromosomal aneuploidy,digyny,and degradation of the cleavage rate.We can improve cryopreserved oocytes to normal fertilization anddevelopment by appropriate incubation and timing of insemination,as the microtubules repolymerize in atime dependent way after incubation which is compatible with recovery of the spindles.With the improve-ment of survival,fertilization,and development,oocyte cryopreservation will play an imperative role.

Objective:To study the optimal process of reflux extraction for lignans from Acanthopanax sessiliflorus roots. Methods:Sesamin as the reference substance, a colorimetric method was used to detect the absorption value of the samples at 558 nm to calculate the content directly. The extraction time, the extraction times and the volume of extraction solvent were applied to optimize the extrac-tion conditions for total lignans by orthogonal experiment. Results:The absorbance had a linear relationship with the amourt of sesamin within the range of 10. 6-53. 0 μg·ml-1(r=0. 999 7). The average recovery of sesamin was 102. 2%(RSD=1. 6%, n=6). The content of total lignans (measurement by sesamin) in the extracts was 10. 0 mg·g-1. The optimum reflux extraction conditions were as follows:adding 40-fold 50 % methanol, extracting once for 30 min. Conclusion:The UV method for determining the total lignans is feasible, stable and reliable as well as precise, and the optimal extraction process is reasonable.
