流行病学

The shape of the segment collected from the patient's feces could changed remarkably by means of contraction and the morphologic characteristics of the proglottids that the width is far more than its length, both the characteristics and the epidemic data are important clue for bertiellosis diagnosis.

司氏伯特绦虫感染者排出的节片因收缩而显著变形，固定后其形态在长宽比例上迥异于其它绦虫，掌握该特征并追溯流行病学线索对诊断具有关键意义。

Our results show that EV71 proliferates in the neural cells and leads to neural cell lesions.

因此，探讨EV71感染神经细胞的生物学效应无论在EV71感染发病机理的研究，还是在EV71感染的流行病学检测措施研究中均具有重要意义。

The IHR are being revised and modernized to adapt to situation of emerging and reemerging disease, changes in epidemiology and control and to substantial increases in the volume of international traffic.

为了适应新出现和再出现疾病的局势、流行病学和疾病控制的改变以及国际交通总量实质性增加，IHR正在进行修改，使之现代化。

Second, research evidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusive. Numerous clinical studies have shown that sugar-containing liquids, when consumed in place of usual meals, can lead to a significant and sustained weight loss.

第一，已出版的关于含糖饮料摄入与肥胖的流行病学研究重新评定表明：大多数这种研究要么是横断面调查要么是基于目前这种趋势的一种被动性的监测，因而研究也存在着允许两者因果关系不成立情况；第二，关于不同类型饮料和固体食物短期内谁更能使人觉得饱胀能力的比较调查还没有结果。

First , a reevaluation of published epidemiologic studies of consumption of sweetened beverages and overweight shows that most such studies either are cross-sectional or are based on passive surveillance of temporal trends and thus permit no conclusions about causal links . Second , research evidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusive .

First, a reealuation of published epidemiologic studies of consumption of sweetened beerages and oerweight shows that most such studies either are cross-sectional or are based on passie sureillance of temporal trends and thus permit no conclusions about causal links. Second, research eidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusie.

首先，加糖饮料的消费与肥胖症之间流行病学的研究的重新评估表明：大部分如此的研究要么是片面的，要么是消极的暂时的趋势考察，因此不能得出两者之间因果关系的结论；其次，拿短期的对不同的固体能量和液体能量的满意程度做比较的研究证据也是不确定的。

Because a study led by a team of Johns Hopkins scientists finds that tailgating such feathered cargo can significantly increase your exposure to poultry-borne bacteria. The report appeared in the very first issue of "The Journal of Infection and Public Health," which will publish research on the epidemiology, prevention and control of infectious disease.

霍普金斯大学的一个科学家小组通过一项研究发现在满载家禽的货车后面行驶能显著地增加暴露于家禽携带的细菌的可能性该项研究正好发表在第一期的《传染和公共健康杂志》（The Journal of Infection and Public Health）该杂志发表有关流行病学、传染病的预防和控制方面的研究工作

in 2950 subjects,including 1472 hbsag positive patients and 1478 hbsag negative control, all of them were obversved in 10 years and the standardized mortality ratio of primary carcinoma of liver were calculated in each group.results:①in hbsag positive groups,the smr were 8.85 in men and 12.50 in women,in hbsag negative groups, the smr were 2.87 in men and 3.40 in women, there were significant difference among different groups;②the trend of correlation between hbsag and primary carcinoma of liver were alike in 5 years before and after;③there were not any significant difference observed about the smr of carcinoma ventriculi and esophagus cancer in different groups.

采用前瞻性研究，自1996年7月起对观察对象随访10年，其中hbsag阳性者1472例，阴性者1478例，于2006年10月用流行病学方法分析各种标化死亡比等观察结果。结果：①hbsag阳性组的肝癌标化死亡比男、女分别为8.85与12.50，hbsag阴性组的肝癌smr分别为2.87与3.47，两组之间差异显著；②hbsag与肝癌的关系在前后5年的趋势相似；③hbsag阴性和阳性组的胃癌及食道癌的标化死亡率无统计学差异。
