【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.
