摘　　要：为探讨人类胚胎组织完整RNA的分离方法及其影响因素,采用液氮研磨及匀浆器两种制备组织匀浆方法,对不同引产方式的人类胚胎组织进行总RNA分离,并对RNA质量进行鉴定。结果发现,液氮研磨组分离完整RNA的阳性率高于匀浆器处理组,分别为68.42%和29.29%,两组比较有显著性差异;药物引产组及非药物引产组在分离完整RNA阳性率、胚胎组织RNA的OD260/OD280比值和胚胎组织βactin基因表达量上均无统计学差异。结论:液氮研磨方法可以应用于胚胎组织匀浆分离完整RNA,而不同引产方式对胚胎组织RNA质量并无直接的影响。To investigate the method of RNA isolation from human embryonic tissues and the factors influencing the quality of RNA, the RNA from human embryonic tissues obtained with drug-induced labor or non-drug induced labor were isolated by using grind with liquid nitrogen or homogenizer without liquid nitrogen. The results showed that the positive rates of RNA integrity in grind with liquid nitrogen group and in homogenizer without liquid nitrogen group were 68.42% and 29.79% respectively, and there was significant difference between these two groups ; however, there was no statistic difference in positive rate of RNA integrity, OD260/OD280 ratio and β-actin gene expression level between the drug-induced labor group and non-drug induced labor group. It is concluded that pulverize of tissue in liquid nitrogen remains the integrity of RNA isolated and may be applied for RNA isolation from human embryonic tissues. The quality of RNA is not affected by different methods of induction of maternal labor.
