Objective:Analysis of screening results of three neonatal diseases to further clarify the incidence of phenyl ketonuria,congenital hypothyroidism and glucose-6-phosphate dehydrogenase(G6PD) deficiency in Hainan Province.
目的:对海南省新生儿疾病筛查情况进行分析,了解海南省新生儿苯丙酮尿症、先天性甲状腺功能低下症、葡萄糖6-磷酸脱氢酶缺乏症(G-6-PDD)的发病率。方法:对出生72h后的7412名新生儿采集足跟血制作血滤纸干标本,PKU筛查采用荧光定量法检测滤纸干血斑中Phe含量;CH筛查采用时间分辨荧光免疫法检测滤干血斑中TSH含量;G6PD缺乏的筛查采用荧光斑点定性试验测定G6PD活性。

Analysis of the obtained genome amplification showed that DNA after PCR presented obvious polymorphism, and the results were the same using the same primer to amplify the larva and imago of the same species. It indicates that RAPD technique can be applied to the identification of dry samples and dipped larva sample of longicorn beetles as well as the research of phylogeny. These three methods for extracting genome DNA from different species of longicorn beetles at different preserved time are feasible.
对所获得的基因组扩增分析表明,经过PCR之后的DNA能呈现明显的多态性,同种天牛用同一引物扩增幼虫和成虫所获得的结果相同,可以认为,RAPD技术可以应用于天牛成虫干标本及幼虫浸渍标本的鉴定及系统发育研究中,也证明了这3种方法用于提取不同保存时间、不同种天牛基因组的DNA是切实可行的。

The maxillofacial and brain injuries were examined. Craniptomy was done to animals of impact injury 6 hours after damage, however it was done to animals of explosive injury in different time point (1 hour, 24 hours, 72 hours, 7 days, 14 days after damage). The pathological characteristics of corelative tissues were examined in detail under light and electron microscopes. The content of LPO, SOD, NO in soft tissue, brain, blood, and cerebral water content were measured, compared with control. The distribution and tissue location of NOS were studied by histochemistical and immunohistochemistic methods. Their relationship was studied to assess the pathological and physiological characteristics of maxillofacial injuries and brain damage associated.
