SUMMARY OBJECTIVE: The aim of this study was to investigate the correlation between the Trial of Org 10172 in acute stroke treatment classification and the National Institutes of Health Stroke Scale score of acute cerebral infarction as well as acute cerebral infarction's risk factors. METHODS: The clinical data of 3,996 patients with acute cerebral infarction hospitalized in Hebei Renqiu Kangjixintu Hospital from January 2014 to November 2018 were analyzed retrospectively. According to Trial of Org 10172 in acute stroke treatment, they were divided into five groups: arteriosclerosis, cardio cerebral embolism, arterial occlusion, other causes, and unknown causes. Through questionnaire design, routine physical examination, and physical and chemical analysis of fasting venous blood samples, the risk factors were evaluated, and the correlation between Trial of Org 10172 in acute stroke treatment classification and National Institutes of Health Stroke Scale classification was analyzed using multivariate logistic regression. In addition, the relationship between National Institutes of Health Stroke Scale score and risk factors in different groups was compared, and the correlation between Trial of Org 10172 in acute stroke treatment classification and National Institutes of Health Stroke Scale score was analyzed. RESULTS: Multivariate logistic regression analysis showed that diabetes, atrial fibrillation or stroke history, age, and education level were related to Trial of Org 10172 in acute stroke treatment classification. In the National Institutes of Health Stroke Scale comparison, the scores of the cardio cerebral embolism group were significantly higher than those of the other four groups, and patients with diabetes, atrial fibrillation, or stroke history had a high share, especially atrial fibrillation (33.06%). CONCLUSIONS: The nerve function defect is more serious after acute cerebral infarction with cardiogenic cerebral embolism, indicating a poor prognosis.

RESUMO Introdução: O estudo e a coleta de parâmetros indiciais da função cardíaca em atletas e a avaliação correta e razoável das funções corporais podem, efetivamente, levar ao ajuste de planos de treinamento e evitar a sobrecarga física de atletas. Objetivo: Estudar o diagnóstico da lesão miocárdica pelo monitoramento cardiovascular em atletas a partir de dois aspectos: a extração de parâmetros característicos da função cardíaca e a pesquisa do processamento de sinais. Métodos: O algoritmo de avaliação inteligente da função cardíaca foi estudado usando a fusão de informações de múltiplas fontes, além da tecnologia embarcada. Sensores em miniatura também foram usados. Resultados: A incidência de arritmia ventricular severa era menor nos dois grupos. A incidência de arritmia sinusal e o bloqueio atrioventricular de segundo grau do tipo I intermitente no grupo de alta intensidade foi significativamente mais alta do que no grupo de controle. O número de batidas prematuras atriais e ventriculares era menor no grupo de controle, mas aumentava consideravelmente no grupo de alta intensidade. Conclusões: Este estudo aplicou a teoria da fusão de informações de múltiplas fontes para conduzir uma pesquisa importante sobre o monitoramento e avaliação inteligentes da função cardíaca de atletas de elite, enfocando as exigências de aplicação do monitoramento da função cardíaca de atletas de elite. Nível de evidência II; Estudos terapêuticos – investigação de resultados de tratamento.

ABSTRACT Introduction: The study and collection of athletes’ heart function index parameters and the correct and reasonable evaluation of body functions can effectively adjust training plans and avoid athletes’ bodily exhaustion. Objective: To study the diagnosis of myocardial injury by cardiovascular monitoring in athletes from two aspects: extraction of characteristic parameters of heart function and research of signal processing. Methods: The heart function intelligent evaluation algorithm was studied by using multi-source information fusion, and embedded technology; miniature sensors were used as well. Results: The incidence of severe ventricular arrhythmia was lower in both groups. The incidence of sinus arrhythmia and intermittent second degree I atrioventricular block in the high-intensity group was significantly higher than that in the control group. The number of atrial and ventricular premature beats was lower in the control group, but increased significantly in the high-intensity group. Conclusions: This study applied the theory of multi-source information fusion to carry out representative research on the intelligent monitoring and evaluation of the heart function of elite athletes, centering on the application requirements of the heart function monitoring of elite athletes. Level of evidence II; Therapeutic studies - investigation of treatment results.

Métodos: El algoritmo de evaluación inteligente de la función cerebral se estudió utilizando la fusión de informaciones de múltiples fuentes, además de la tecnología embebida. Sensores en miniatura también se utilizaron. Resultados: La incidencia de taquicardia ventricular severa era menor en los dos grupos. La incidencia de arritmia sinusal y bloqueo auriculoventricular de segundo grado del tipo I intermitente en el grupo de alta intensidad fue significativamente más alta que en el grupo de control. El número de contracciones prematuras auriculares y ventriculares era menor en el grupo de control, pero aumentaba considerablemente en el grupo de alta intensidad. Conclusiones: Este estudio aplicó la teoría de la fusión de informaciones de múltiples fuentes para conducir una investigación importante sobre el monitoreo y evaluación inteligentes de la función cardiaca de atletas de élite, centrando las exigencias de aplicación del monitoreo de la función cardíaca de atletas de élite.

Crystallization kinetics and nanocrystalline induced brittleness in an in-situ dendrites reinforced Ti44Zr20Nb12Cu5Be19 bulk metallic glass (BMG) composites were investigated. The activated energy of the present Ti-based metallic glass matrix is obtained to be about 201 KJ/mol. As the annealing temperature rises, the annihilation of free volume is believed to cause the increase of hardness and the decrease of plasticity. Brittle fracture occurs after the precipitation of nanocrystalline, which can be ascribed to the formation of the microcracks in the matrix during deformation.
