In conclusion, the results of multilevel model analysis showed that the GERD score of resident in Wuhan was relatively higher and had significant difference with that in Guangzhou, however, that in Shanghai, Beijing and Xi\'an had no significant difference compared with that in Guangzhou. That is to say, the prevalence of GERD in Wuhan was relatively higher compared with the other four survey sites; the residents'health status more worse, the GERD score more higher, and the influence of health status on GERD score was also effected by the region difference between Wuhan and Guangzhou; residents lived in rural region with lower education level, worse spirit status were more likely to suffer from GERD; Moreover, those residents who had family history of GI tumors or other GI diseases, some anamneses (such as dyspepsia, gastritis, rheumatic arthritis), and some diseases (such as irritable bowel syndrome and aerophagia) were also more likely to report GERD. However, no significant association was found between GERD and some other factors in this survey, such as sex, age, etc.

总之，多水平模型分析结果显示，与广州相比，上海、北京和西安居民的GERD总评分没有明显的差异，而武汉居民的GERD总评分则相对较高，即表示武汉的GERD发病率在5个调查城市中相对较高；居民的总体健康状况越差，其GERD总评分越高，且其对GERD总评分的影响受到武汉与广州之间地域差异的影响；农村居民、文化程度越低、精神状况越差者更容易患GERD；另外，那些有胃肠道疾病或肿瘤家族史，既往患有胃炎、消化不良、风湿性关节炎，现患有肠易激综合征、吞气症的人，患GERD的可能性更大，而性别、年龄等因素，本研究未发现其与GERD有显著的关系。

二。采用蜱传播试验，研究了璃眼蜱蜱种、长角血蜱和微小牛蜱对牛的巴贝斯虫未定种的传播能力与传播方式：为了确定小亚璃眼蜱、残缘璃眼蜱、麻点璃眼蜱、长巴贝斯虫未定种的发现及牛巴贝斯虫病的免疫诊断和药物防治研究角血蟀和微小牛蟀对在我国分离的牛的一种未命名的巴贝斯虫的传播能力与传播方式而进行了研究。

Investigating the ecology environment and present situation of the endemic Cycas plants to Yunnan, especially the population structure and dynamics of C. Hongheensins and C. tanqingii. The results show that C. hongheensis is a critically endangered species because the number its individuals had decreased by 47% from 1992 to 2002 and no flowering and fruiting tree has found. While the population of C. tanqingii in Xiaoheijiang River is in a status of restoration because there are more young individuals and its age structure takes on the relatively stable shape of pyramid.

对云南苏铁属特有植物的生态环境、现状等进行了较为全面的调查，特别是对红河苏铁、潭清苏铁的种群结构和动态进行较为详细的调查，结果表明红河苏铁是一个极度濒危的种，2002年的个体数量比1992年减少了47%，连续3年的调查未发现具繁殖能力的个体；而潭清苏铁种群的年龄结构基本呈金字塔形，属较稳定的结构，且处于恢复期，繁殖更新基本正常。

"The results of Dr. Felice's study are consistent with the findings of 7 published studies specifically designed to test the hypothesis that easier access to EC promotes risk-taking," Dr. Trussell told Medscape."All of these studies showed that easier access did not result in more unprotected sex and did not reduce the use of regular contraceptive methods."

Trussell医师向Medscape表示，Felice医师研究的结果和7项发表的研究发现一致，那7项研究特别是设计来检验，易於取得EC是否会让高危险性行为比例升高的假设；这些所有的研究显示，EC的容易取得EC并不会造成更多未防护的性行为，且不会减少一般避孕法的使用。

It can be concluded from the experiment results that hatchery seed has lower genetic variation and large-scale hatchery seed releasing affects the genetic diversity of the natural population. The shrimp distributed along China coast in Bohai Sea and Yellow Sea may consist of more than one populations. The viral disease resistant ability of F. chinensis is proved to be genetically inherited and can be improved by genetic selection.

通过对实验结果的进一步分析认为：中国对虾人工育苗的过程使后代群体的遗传多样性下降，人工培育苗种的大规模放流影响了自然群体的遗传多样性；，分布于我国沿海的中国对虾可能由多个自然群体构成，还存在未被发现的种质资源；中国对虾抗WSSV病毒感染是由遗传决定的，选育可提高中国对虾对WSSV的抗性。

PCR and electron microscope were used to detect the virus in the ovaries,eggs atdifferent development stages,and naupliuses of infected broodstocks of P.chinensis.Thevirus was not found in eggs just spawned or not,but in the connective tissue of ovary.Thedetected results of nauplius were positive,and virus-like organisms were found to invadethe epidermis tissue of nauplius.The virus was not detected in the yolk as well as inner andouter membrane of egg.

本文利用PCR及电镜技术，对中国对虾染病亲虾的卵巢和各期卵及其刚孵化出的无节幼体进行了病毒检测，染病亲虾刚产的卵及未产出的卵均没有发现病毒存在，在卵巢的结缔组织中检测到病毒存在，刚孵化出的无节幼体PCR检测结果呈阳性，电镜下观测到有病毒样颗粒侵染无节幼体的上层表皮组织。

The substrates for measuring the activity of individual CYP in vitro included phenacetin, tolbutamide, debrisoquine, and omeprazole. RESULTS: Ther...

结果：CYP1A2、2C9及3A4的含量和活性具有很大的个体间变异，另外CYP2D6的活性在各样本间也有很大差异；CYP3A4(32％)是中国人肝微粒体中含量最丰富的CYP，CYP2C9(19％)和CYP1A2(16％)的含量也很可观；除了CYP1A2的含量和活性具有一定的种族和性别差异外，未发现其它CYP具有种族和性别差异；CYP1A2、2C9和3A4的酶蛋白含量分别和它们的活性具有很好的相关性。

In the centrifuge model test of the construction of Chahanwusu CFRD on deep overlying, the conclusion was drawn, namely it is feasible that the CFRD be construction on deep overlying, with the toe slab directly construct on deep overlying, the vertical seepage control by concrete cut-off wall, and the connection of cut-off wall and toe slab by two connect slabs.

从试验结果上看，虽然蓄水后连接板、趾板都有向上游的移动，但未发现防渗墙顶、连接板和趾板间有明显的拉开现象，说明从结构受力变形的角度来看，坝体坝基的防渗系统的防渗功能是可以保证的； 2。

"Atrial fibrillation is a well-known risk factor for stroke in the elderly," Dr. Tuula Pirttila, of Kuopio University Hospital, Finland, and colleagues write."Several studies have shown that AF predicts the development of poststroke dementia, whereas others have found no such association."

芬兰Kuopio大学医学院的Tuula Pirttila医师称&心房颤动是老年中风患者显著的危险因素&，他的同事表明&几项研究曾显示心房颤动可预测中风后痴呆的发生，但其他的研究则未发现两者间存在联系。&
