ABSTRACT
In this study,we analyzed the data of hemorrhagic fever with renal syndrome (HFRS) and host animals monitoring in Zhangzhou City,Fujian Province,China,2006-2015,in order to find out the epidemic situation and risk factors,and provide a scientific basis for the prevention and control strategy.A total of 171 HFRS cases,including 1 death,were reported in Zhangzhou in this decade.The incidence rate of 0.352/105 showed an upward trend (xtrend2 =58.60,P＜0.01).And 70 villages and towns in 11 counties have affected,accounting for 56.00％ of the counties in Zhangzhou City.The cases were mainly reported in some towns of Huaan,Nanjing and Zhaoan countries.The cases mainly occurred in countryside,which reported 142 cases.The cases in farmers accounted for the highest proportion (79.58 ％),and pig farming staff accounting for 23.01％ in farmer cases.Most cases were reported in municipal hospitals (86.55 ％).The common clinical manifestations of those cases were fever,nausea,vomiting,backache,headache,pain,oliguria or anuria,eyelid edema and so on,with 72.67％ of thrombocytopenia and of 83.09 ％ proteinuria positive.Compared with the proportion (80.49 ％) of mice in patients' house from 2006 to 2010,that (45.83％) from 2011 to 2015 decreased obviously;however,the proportion of mice or mice droppings in workplaces were rising from 60.98％ to 73.33％.Mean rodent density was 6.40％ and total infection rate in rats was 7.42％.The main kind of rats with virus infection was Rattus norvegicus,carrying Seoul virus Ⅱ.Results of this study indicate that Zhangzhou is one of the foci of HFRS rodent,and the epidemic is rising in recent years,the overall in the highly distributed,while some counties showed a rising trend year by year.Thus,monitoring and control efforts in prone areas should be increased,and to carry out clinics training of HFRS in primary health care institutions.
ABSTRACT
Objective:To compare diagnostic effect between coronary CT angiography (CTA) and intravascular ultra-sound (IVUS) for coronary calcified lesion .Methods:A total of 50 patients ,who were diagnosed as coronary heart disease (CHD) or suspected CHD in our hospital ,were selected .All patients received coronary CTA and IVUS ex-amination .Characteristics of coronary artery plaques and CT values of different types of plaques were observed , coronary CTA diagnostic effect was evaluated according IVUS as control .Results:There were no significant differ-ence between two methods in plaque area ,plaque burden and lumen area;CT value of calcified plaques was signifi-cantly higher than those of fibrous plaques and fatty plaques [ (725.68 ± 68.42) Hu vs .(58.12 ± 7.05) Hu ,(60.21 ± 6.78) Hu ,P<0.01 both];Sensitivity ,specificity ,accuracy ,positive predictive value and negative predictive val-ue of coronary CTA for diagnosing calcified plaques were 92. 86% ,92. 86% ,92. 86% ,81. 25% and 97. 50% respec-tively .Conclusion:Coronary CT angiography possesses higher diagnostic effect for qualitative and quantitative de-tection of coronary calcified lesions ,which can be regarded as a preferred screening method .
ABSTRACT
Objective To analyze the differences of hospitalization mortality of coronary stenting in patients with coronary heart disease between the elderly (≥65 years old ) and non elderly. Methods Totally 3252 patients who underwent coronary stenting in Guangdong Provincial People’s Hospital were studied retrospectively. They were divided into elderly group (≥65 years old, n=1344) and non elderly group (
