Design of Rehabilitation Training System with Electromyography Feedback for Stroke Patients / 中国医疗器械杂志

This paper proposed a rehabilitation training system with electromyography (sEMG) feedback for stroke patients based on ARM embedded system and LabVIEW. The system can achieve real-time acquisition, processing and dualview of multi-channel sEMGs and compute related sEMG parameters including iEMG, RMS, MPF and co-contraction ratio. The system was detected by clinical experiments and related inspection department. The result showed that the system is functional, interactive and in accordance with the relevant standards for medical devices so that it can fully satisfy the clinical demands. In addition, the system can help doctors to master the training state of the patient more effectively in a real-time and quantitative way that is direct to improve the training programs of stroke patients.

Early-onset and Late-onset Ventilator-associated Pneumonia:Their Etiology / 中华医院感染学杂志

OBJECTIVE To probe the pathogen′s distribution of ventilator-associated pneumonia(VAP),in order to offer the evidence of clinical therapy,prevent the onset of VAP and apply the antibiotics reasonably.METHODS We applied the methods of etiology,microscopic identification,bacteria culturing etc on 74 mechanical ventilation patients,and analyzed the etiology of early-onset and late-onset VAP in contrast.RESULTS Totally 121 pathogens were cultivated altogether in all 74 VAP patients.In the 36 pathogens which were cultivated from 29 early-onset VAP patients,there were 66.67% of simple culture(24 patients,24 strains) and 33.33% of co-culture(5 patients,12 strains),and in the 85 pathogens which were cultivated from 45 late-onset VAP patients there were 17.64% of simple culture(15 patients,15 strains) and 82.35% of co-culture(30 patients,70 strains).The proportion of co-culture in the late-onset VAP patients was prominantly higher than that in the early-onset ones(?2=27.821,P
