云南省伤寒副伤寒空间分布特征及其气候影响因素研究   总被引:7,自引:6,他引:1  
Objective To characterize the spatial distribution of typhoid and paratyphoid fever(TPF)in Yunnan province, China and to determine the effectiveness of meteorological factors on the epidemics of TPE Methods Data of reported TPF cases in Yunnan province(2001 -2007)from the China Information System for Diseases Control and Prevention was applied to GIS-based spatial analyses to detect their spatial distribution and clustering of TPF incidence at the county level.Panel data analysis was used to identify the relationships between the TPF incidence and meteorological factors including monthly average temperature, monthly cumulative precipitation and monthly average relative humidity. Results During the study period, the average incidence of TPF in Yunnan province was 23.11/100 000, with majority of the TPF cases emerged in summer and autumn. Although widely distributed, two TPF clusters were detected in Yunnan province based on the spatial analysis:one area around Yuxi city with the average annual incidence as 207.45/100 000 and another at the junctions of Yunnan province with Burma and Laos. Based on results from panel data analysis, the incidence of TFP was shown to be associated with meteorological factors such as temperature,precipitation, relative humidity and one month lag of temperature increase [10 ℃ increase in the monthly average temperature:IRR=1.30(95%CI: 1.24-1.36);10% increase in monthly average relative humidity:IRR= 1.07(95%CI: 1.05-1.09); 100 mm rise in monthly cumulative precipitation:IRR=1.02(95%CI: 1.00-1.03); and 10 ℃ average temperature increase, the last month: IRR=1.73(95%CI: 1.64-1.82)]. Conclusion Areas with high TPF incidence were detected in this study,which indicated the key areas for TPF control in Yunnan province. Meteorological factors such as temperature, precipitation and humidity played a role in the incidence of TPF.  相似文献

Abstract:
Objective To study the association between temperature and daily mortality from June 1, 2006 to December 31, 2009 in Guangzhou. Methods Time series approach was used to estimate the impact of temperature on the rates of total and cause-specific daily mortality. We fitted generalized additive Poisson regression using non-parametric smooth functions to control for the long-term time trend, day of week, air pollution and other weather variables. Results A slight sloping U-like relationship between the total mortality and temperature was found, with an optimum average temperature (temperature with lowest mortality risk) value of 19.7 ℃ in Guangzhou. For temperature above the optimum value, the relative risk of total mortality increased by 3.0% (RR=1.030,95%CI: 1.011-1.050) for each increase of degree in Celsius. For average temperature below the optimum value, the relative risk of total mortality and diseases of circulatory system had a 3.3%(RR=0.967,95%CI: 0.936-0.997 ) decrease and a 3.6% ( RR= 0.964,95%CI:0.935-0.994 ) increase,for each degree of Celsius increase, respectively. Conclusion Our findings showed that the temperature had an impact on the daily mortality in Guangzhou. Countermeasures needed to be taken to reduce the temperature related mortality.  相似文献

Objective To construct a full length cDNA library of the dominant strain of Penicillium marneffei (PM) in yeast phase isolated from AIDS patients in Guangdong province and screen UniGenes as well as full-length genes, so as to establish the foundation for the study of PM's functional genes and pathogenic mechanisms. Methods CloneMiner cDNA construction kit was utilized to extract mRNA of the dominant PM strain isolated from AIDS patients in Guangdong province. The mRNA was reversed into cDNA, then cloned into a pDONR222 vector by BP recombination to obtain an Uncut cDNA library, which was homogenized later to construct a normalized cDNA library with the principal of saturation hybridization for DNA genome. 2000 clones were chosen randomly to make a bi-directional sequencing and analyzed with bioinformatics for screening UniGenes and full-length genes. Results The total clone number of the Uncut cDNA library was 1.16 × 107 cfu/mL, with a recombination rate of 95% and an average insertion element being over 1 kb. The total clone number of the normalized cDNA library was 1.18 × 106 cfu/mL, with a recombination rate of 95% and an average insertion element being over 1 kb as well. 1945 genes which DNA length were longer than 1 kb were obtained by sequencing and merged into 1360 UniG enes, of which 632 genes were full-length ones. Conclusions The full-length cDNA library of the dominant strain of PM from AIDS patients in Guangdong province possesses good quality.Meanwhile, the technical routine presents high efficiency in obtaining full-length genes and establishing a gene expression spectrum, which can contentedly meet the needs of future experiments.  相似文献

Objective To analyze the region cluster and risk factors of hypertension in the Chinese adult population and to explore the application of multilevel regression model in the risk factors of hypertension. Methods Multi-stage random sampling technique was used to choose 15 540 individuals aged 35-74 years from 10 regions in China. Two-level logistic regression models were fitted under MLwiN 2.02 software. Results The region cluster of hypertension existed and variance portion coefficient was 3.1%. After adjusting for the age and gender, overall obese people (BMI≥28 kg/m2) were 4.50(95%CI: 4.00-5.06) times, overweight people (BMI=24-27.9 kg/m2) were 2.26 (95%CI: 2.07-2.46) times more likely to be hypertensive as compared with those of normal BMI (18.5-23.9 kg/m2), and those centrally obesive people (Waist circumference≥85 cm in male or 80 cm in female) were 2.62 (95%CI: 2.42-2.83) times more likely to be hypertensive as compared with those of normal WC. The age-and gender-adjusted odds ratios (Ors) of triglyceride (TG), serum total cholesterol (TC), glucose, low-density lipoprotein cholesterol (LDL-C) , high-density lipoprotein cholesterol (HDL-C) and drinking alcohol were 2.10 (95% CI: 1.89-2.33) , 2.08 (95% CI: 1.84-2.35) , 1.85 (95% CI: 1.60-2.14) , 1.58 (95% CI: 1.38-1.81), 1.49(95%CI: 1.32-1.69) and 1.15(95%CI: 1.05-1.27), respectively. Conclusion The prevalence of hypertension was not only affected by individual risk factors, such as obesity, drinking alcohol, abnormal glucose and serum lipids profile, but also affected by the geographic environment where people resided in. Population-and risk factors targeted strategies, proved a promising way to reduce individual risk of hypertension in the primary prevention of hypertension.  相似文献

Hospitals all over Europe must get ready to face the important challenge of 1993 at all levels: micro-economic, macro-economic, local, regional and European. Despite the liberalization trends which will inevitably appear with the increased freedom of exchange and movement, hospitals must strive to remain havens of peace to patients.  相似文献

The prevalence of overweight and obesity in children is increasing rapidly. This is alarming because obesity is associated with severe chronic diseases, such as type 2 diabetes mellitus. Obesity at young age is related to obesity at adult age. Consequently, the prevention of overweight from childhood onwards is an important issue. Apart from diabetes mellitus type 2 there is an increased risk of orthopaedic complications, respiratory problems, fertility problems, cardiovascular diseases and psychosocial consequences in the form of a negative self-image, emotional and behavioural problems and depression. Environmental and behavioural factors are regarded as the most important causes of the rapid increase in the prevalence of overweight and as the most important starting points for prevention. Most prevention programmes are still in the initial stages. Prevention programmes aimed at stimulating breast feeding and daily physical activity (playing outside) and the restriction of sweetened drinks and watching TV are very promising. With such preventive measures the involvement of both the school and the parents is important.  相似文献
