Worldwide, hypertension is one of the most common causes of death. The prevalence of hypertension and cardiovascular disease increases with age, and has been found to be higher in those of South Asian and African ancestry, and in Aboriginal populations. Hypertension is not only one of the most important risk factors for cardiovascular disease, but also the number one modifiable risk factor for stroke. Alterations in blood coagulation system have been reported in patients of hypertension. Fibrinogen has been identified as a major independent risk factor for cardiovascular diseases. This was a descriptive cross-sectional study, conducted in Elobied teaching hospital during period from March to June 2014. The aim of this study is to determine the level of fibrinogen among hypertensive patients. Seventy percent of the patients (about 35 patients) had high fibrinogen level above 400 mg/dl compared with the control and about 30% (15 patients) were within the normal range of 200 mg - 400 mg/dl. This study has concluded that there was a significant increase in fibrinogen level in hypertensive patients compared to control, while the gender has no effect on the level of fibrinogen.展开更多

This article proposes the concepts and methodology for top-level design of smart cities based on the ＂ Integration of Four Plans ＂, and the planning process and systems for implementing the top-level design of smart cities. This article discusses, from the perspective of a city, how to optimize resource allocation, coordinate the development of urban economy, society, resources, environment, and people＇s livelihood, and map out the blueprints for healthy and sustainable development of a smart city.展开更多

The linear regression shows that δ18O changes (0.9995‰ for benthic foraminifers and 1.022‰ for planktonic foraminifers) are equal to 100 m in sea-level fluctuation. After making temperature correction in the δ18O record of benthic foraminifers from 72 to 120 Ka B.P., the curve of sea-level oscillation of the South China Sea since 186 Ka B.P. has been reconstructed. The lowermost sea - level that occurred in the last glacial maximum and oxygen isotope stage 6 is approximately - 130 m.展开更多

In Chanchun city, smallsand descending with snow provides the best samples to conduct a quantitative research on the possible impacts of city - ecology. In the 253km2 urban district area of Changchun city, smallsands accumulated up to more than 3000t on April 7, according to the calculation of four "mud - snow" samples. After naturally melting in room temperature, two samples are taken to do quarantine of "invasion bacteria". As a preliminary result, the individual amount of bacterium in 1 ml sample water is up to 8. 9 x 104 or 1. 05 x 105, and it is estimated that there are 640 million "invasion bacterium" individuals in one square meter. This study proves that other than the obvious environmental effects of sandstorm, the urban micro - ecosystem is very possible under threat by the "invasion bacterium" accompanied by remote descending smallsand.展开更多
