A genetic epidemiologic case-control study with 297 pedigrees (79 genealogies and 198 controls) was carried out to estimate the segregation ratio and hereditability (h2 ) of gastric cancer by the methods of Li-Mantel-Gart and Falconer.

通过遗传流行病学病例对照研究，对泰兴市297个家系(先证家系79个，对照家系198个)，应用Li-Manel和Falconer方法进行了分离比及遗传度的估算。

A better understanding of these mechanism will provide rational precautionary measures for topiramate–related hypohidrosis and a new therapy for hyperhidrosis. Therefore, in this study, baseline data as well as therapeutic effect and adverse events of 10,106 patients with epilepsy participated in national topiramate post-marketing surveillance were reviewed.

本课题首先应用流行病学研究方法，回顾分析参加2002年全国托吡酯上市后疗效和安全性监测多中心观察的10，612例癫癎患者的资料，探讨托吡酯引起的泌汗障碍的发生率、临床转归及危险因素，以期加深对这种不良反应发生规律的认识，并为其发生机制的研究提供线索。

It is shown that G gene has the highest speed during the evolution and has uniqueinquilinous body in order to escape immune pressure from inquilinous body byanalyzing phylogenic trees of five genes in the whole genome. In the evolution of Ggene, DRV and MRV are in different groups. DRV, Chinese vaccine isolated used inhuman and Japanese vaccine isolated used in human are in the same group. MRV,CVS and street viruses isolated from dogs are in the some group. It is shown thatDRV is vaccine isolated compared with phylogenic trees of other genes, and it istestified previous conclusion that unqualified vaccine used for human was used nearthe infected beer cote resulted in spotted deer infected.

对狂犬病毒基因组5个基因的分子进化树分析表明，为了逃避宿主的免疫压力，G基因的进化最快速，而且具有宿主的特异性，在G基因的进化中，DRV和MRV分别位于不同的组群，DRV与中国人用疫苗株和日本疫苗株在一个组群，MRV与CVS以及犬脑分离的街毒归在一个组群，结合其他基因的进化树表明，DRV与疫苗株具有较近的亲缘关系，从分子水平验证了以前对DRV流行病学调查得出的推测，在狂犬病疫情发生的鹿场附近曾使用过人用狂犬病疫苗，导致梅花鹿感染狂犬病毒。

Methods Blood spot filter paper samples with related epidemiological data were collected from vivax malaria patients living in malarious area of 10 provinces in China. Semi nested or nested allelic specific PCR genotyping method was used to identify CSP genotypes, families and types of Plasmodium vivax of each isolate from these patients.
