【Abstract】 Background From March 2014 to October 2015,Ebola virus disease (EVD) in the Republic of Sierra Leone caused 8 690 cumulative confirmed cases and 3 588 deaths country-wide.Understanding the epidemiological characteristics of EVD deaths is of great significance for improving disease resistance and reducing disaster losses.Objective To analyze the epidemiological characteristics of EVD deaths.Methods The retrospective study of the morbidity,mortality,and time and geographical distributions of death cases of EVD was done with clinical and demographic data mainly collected from medical records of Jui Government Hospital from March 2014 to October 2015,and with supplemented data from records of National Ebola Response Center of Sierra Leone(http://www.nerc.sl/) and World Health Organization(http://www.who.int/csr/disease/ebola/en/).Other data of 747 EVD cases(442 survived and 305 died) diagnosed by Jui Government Hospital were also collected,including gender,age,interval between EVD onset time and admission time,viral load,clinical symptoms,length of stay,discharge or death time.Results In Sierra Leone from March 2014 to October 2015,the incidence rate of EVD was 0.12%(8 690/7 120 722),and the case fatality rate(CFR) of EVD was 41.28%(3 588/8 690).On March 31,2014,the Ministry of Health of Sierra Leone reported 6 possible and suspicious cases,of whom 5 died (case fatality rate was 5/6).It fell to a lower level in September 2014 〔29.94% (605/2 021) 〕 and remained basically at a lower level after December 2014.CFR of EVD in Freetown,the capital city,was lower〔38.88%(1 341/3 449)〕.Districts near the capital showed relatively lower CFR,but those far from the capital showed relatively higher CFR.The decreased had greater average age,longer average interval between onset time and admission time,higher rates of weakness,abdominal pain,dyspnea,skin rash and disturbance of consciousness,but had lower average viral load (CT value),and lower rates of fever,vomiting,anorexia,and joint pain compared with the survived(P<0.05).Multivariate Logistic regression analysis found that the interval between EVD onset time and admission time〔OR=1.510,95%CI(1.373,1.661)〕,viral load (CT value) 〔OR=0.937,95%CI(0.892,0.985)〕,vomiting 〔OR=0.576,95%CI(0.343,0.966)〕,weakness〔OR=0.162,95%CI(0.049,0.533)〕,dyspnea〔OR=1.715,95%CI(1.025,2.871)〕and disturbance of consciousness〔OR=0.389,95%CI(0.217,0.696)〕were independent prognostic factors of EVD(P<0.05).Conclusion Several factors influenced the outcome of EVD.Coordinated international response is deemed essential to reduce the death cases.Transportation condition could be one of the main factors relating to the mortality rate,earlier admission would improve the prognosis.Older age is associated with a higher risk of death.Clinical characteristics including vomiting,weakness,dyspnea and disturbance of consciousness are also related to prognosis of the disease.

【Abstract】 Background As one of the most important geriatric syndromes,frailty seriously affects the quality of life and the survival time of the elderly patients undergoing chronic hemodialysis.Infection is also considered to be an important factor affecting the prognosis of elderly dialysis patients.Objective To investigate the incidence of infection and its relationship with frailty in elderly patients on maintenance hemodialysis (MHD).Methods A total of 115 elderly patients on MHD admitted in the Blood Purification Center of the Second Affiliated Hospital & Yuying Children's Hospital of Wenzhou Medical University were recruited into our study from January 2015 and January 2016.Infection was recorded and clinical data and blood biochemical data of enrolled patients were collected in the one-year follow-up.Frailty was assessed by Fried's Frailty Phenotype,and the correlation of infection and frailty was analyzed by Spearman's rank correlation coefficient analysis and multivariate Logistic regression analysis. Results After one-year follow-up,41 cases (35.7%) had infection.There were significant differences between the infection group and the non- infection group in C-reactive protein (CRP),plasma albumin,pre albumin,monocyte chemoattractant protein 1 (MCP-1) and frailty (P<0.05).Spearman's rank correlation coefficient analysis showed that infection was positively correlated with CRP,MCP-1 and frailty (rs=0.187,0.269,0.239,P=0.045,0.004,0.010,respectively),while it was negatively correlated with plasma albumin,pre albumin levels (rs=-0.216,-0.192,P=0.021,0.041).Multivariate Logistic regression analysis showed that CRP 〔OR=1.008,95%CI(1.007,1.095)〕,MCP-1 〔OR=1.008,95%CI(1.001,1.014)〕 and frailty 〔OR=1.997,95%CI(1.156,3.450)〕 were the independent risk factors for the progression of infection in elderly patients on MHD.Conclusion A high prevalence of infection occurred in elderly patients on MHD. CRP,MCP-1 levels and frailty are the risk factors for aggravation of infection in such population.

【Abstract】 Epilepsy is a group of chronic neurological disorders caused by excessive neuronal activity in the cortex of the brain.Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive neuroelectrophysiological technology which can modulate cortical excitability.Researches have showed that rTMS delivered into epileptogenic foci had an antiepileptic effect on patients with refractory epilepsy or status epilepticus and appears to be safe.Thus,rTMS may become one of the most promising neuro-stimulation modalities for refractory epilepsy.Further multi-center,large-sample randomized controlled trials are warranted to provide basis for evidence-based medicine.Meanwhile,rTMS for treatment of epilepsy still faces some challenges,especially on how to map targets accurately and how to prolong the treating effect.Based on present key problems,future researches should focus on developing high-resolution positioning technology,optimizing equipment and stimulus mode and exploring brain network connections and relevant TMS mechanism.

【Abstract】 With the wide application of highly active antiretroviral therapy (HAART),and the acceleration of HIV-infected population aging,studies about the relationship between stroke and HIV infection have received increasing attention.Stroke is considered to be a serious complication after HIV infection,with high mortality and disability.At present,the epidemiology and pathogenesis of the disease are not completely clear,and there are no effective prevention and treatment measures.This article reviews recent developments in epidemiology,pathogenesis,prevention and treatment,and TCM knowledge concerning HIV-infected patients with stroke,in order to provide a reference for the prevention and treatment of HIV-related stroke.
