发病

A missense mutation （p.H1075R） in the ADAR gene has been detected in this DSH family, which is probably one of the pathogenetic molecular bases.

该家系发病是由ADAR基因突变所致，其发病的基因型和表型之间的关系有待进一步研究。

The researches show that the substrate plays an important role in the development of keratoconus. Cornea substrate's agenesis leads to the reduced solidity, which is possibly related to kearatoconus. There is still a lot to be researched on etilogy and early diagnosis of keratoconus.

虽有研究表明角膜间质的水平在圆锥角膜的发病中起重要作用，角膜间质发育不全，导致角膜的稳固性下降，可能与圆锥角膜形成有关，但对圆锥角膜形成的机理仍不详尽，因此，对圆锥角膜的发病机制及早期诊断的研究具有重要意义。

According to the malaria statistics in 1989,the number of malaria cases,malaria incidence and positive parasite rate in native resident fever cases,and the number of malaria loci decreased by 20%,21.79%,35.85% and 31.06% respectively in comparison With that in 1988·In addition,the malaria transmission peak dropped down·All these achievements are due to strengthened antimalaria measures,especially in the areas where malaria incidence was higher.

1989年全省疟疾发病人数，发病率，当地发热病人血检疟原虫阳性率和疟疾病灶点数分别比1988年下降20.4%、21.79%、35.85%和31.06%，压低了9月份的发病高峰。

Methods Using Grey model （ 1 : 1 ）, autoregression model, ARIMA model to fit the data of the incidence rate in our country from 1984 to 2006, and predict the incidence rate of malaria in later years.

探讨不同模型在疟疾发病预测中的应用，并预测疟疾在中国未来的发病趋势。

More than 90% of the total incidence of typhoid and paratyphoid were typhoid previously, as the widely use of Vi bacterin, in the middle of 90s in 20th century, the popular strain changed, in some provinces the cases of typhoid decreased, but that of paratyphoid increased largely, with the outbreak trend from spot to part and from inshore provinces to backland provinces. In recent years, paratyphoid becomes the main infectious diease in some areas, and ofen develop to serious epidemic situation. So setting up a rapid and accurate detecting metod is necessary.

以前我国伤寒发病占伤寒副伤寒总发病的90%以上，后来由于伤寒Vi疫苗的广泛使用，20世纪90年代中期，流行菌株发生转变，我国部分省份伤寒病例逐渐下降，而由甲型副伤寒沙门氏菌引起的副伤寒病例却大幅上升，并呈现由散发到局部暴发，由沿海省份向内地省份推进的流行趋势，近几年来成为我国一些地区传染病突发事件的主要病种，常发展成重大疫情，急需建立快速、准确的诊断方法。

In order to master the occurrence of wheat leaf blotch and evaluate resistance of wheat cultivars in Henan Province from 2005 to 2007, 49 wheat cultivars were selected and their resistance to wheat leaf blotch were identified.

在自然发病条件下，系统调查了河南省主栽小麦叶枯病在2005年－2007年的田间发病情况，并采用自然病圃法鉴定了49个小麦品种对叶枯病的抗性。

Not only have the recipients and the donor not progressed to disease for 15 years," marvels molecular biologist Nicholas Deacon of Australia's Macfarlane Burnet Centre for Medical Re-search,"but the prediction is that they never will.

伯奈特医学研究中心的分子生物学家迪肯啧啧称奇："捐血人与输血人不仅15年来没有发病，而且应该永远不会发病。"

Methods Community-based comprehensive prevention was implemented in the intervention community,such as health education,hypertension controlment and cerebrovascular disease's incidence and mortality surveillance.

在干预社区采用强化以脑血管病为主的卫生健康知识的宣传，管理高血压为主的综合性预防措施，监测脑血管病发病病例；在监测社区仅监测脑血管病的发病病例。

Abnormal expression of type Ⅰ～Ⅵ could be found in the onset of illness. The decreasing of collagen could causes the weaken of the stability of stroma lamellar and the cornea shap to conus. The onset of keratoconus is related to collagen

胶原Ⅰ～Ⅵ型的表达在圆锥角膜的发病过程中有明显的变化，胶原成分的减少会导致角膜的机械抵抗力减弱，并使角膜前凸变薄，最终影响角膜的正常形态，圆锥角膜的发病与胶原密切相关。
