An integrated GIS-based analysis system （IGAS）, supporting assessment of forest land-use and land suitability for the study area where along Laos-China border was developed. Multi criteria analysis and system dynamics techniques were used to assess forest land use and land suitability and to forecast potential land-use for tea. The total study area is estimated at 10 325.07 km2 according to the field data collection and data analysis. The area of current forest cover decreased rapidly from 6337.33 km2 （61.38%） in 1992 to 5106.28 km2 （49.46%） in 2002 in the study area. The current forest was mainly trans-ferred to potential forest and permanent agriculture especially to rubber plantation areas even in the National Conservation Biodiversity Conser-vation Areas. The main causes of forest land use change are poverty. In order to address the problems, land suitability classification for tea was developed based on the multi-criteria. And finally two options of land suitability classification for tea for the study areas were developed.展开更多

We undertook this study to examine a hypothesis that aspirin resistance may be associated with metabolic syndrome, and to assess other potential determinants of aspirin resistance in patients with cardiovascular disease （CVD）. Methods A total of 469 elderly patients with CVD were recruited. One hundred and seventy-two patients with metabolic syndrome and 297 without metabolic syndrome （control group） received daily aspirin therapy （〉 75 mg） over one month. Platelet aggregation was measured by light transmission aggregometry （LTA）. Aspirin resistance was defined as 〉 20% arachidonic acid （AA）- and 〉 70% adenosine diphosphate （ADP）-induced aggregation according to LTA. Aspirin semi-responders were defined as meeting one （but not both） of these criteria. Results By LTA, 38 of 469 （8.1%） patients were aspirin resistant. The prevalence of aspirin resistance was higher in the metabolic syndrome group compared with the control group [11.6 % vs. 6.6%, odds ratio （OR） = 2.039; 95% confidence interval （CI）： 1.047-3.973]. In the multivariate logistic regression analysis, metabolic syndrome （OR = 4.951, 95% CI： 1.440-17.019, P = 0.011） was a significant risk factor for aspirin resistance. Conclusions A significant number of patients with CVD and metabolic syndrome are resistant to aspirin therapy. This might further increase the risk of cardiovascular morbidity and mortality in these patients.展开更多
