ABSTRACT
Objective@#To investigate the nursing effect of clinical treatment combined with early rehabilitation nursing intervention in patients with heart failure.@*Methods@#A total of 60 cases of patients with heart failure from January 2018 to May 2018 in Beijing Anzhen Hosipital, Capital Medical University were admitted. They were divided into control group (30 cases) and observation group (30 cases) by random digits table method. All patients in 2 groups were treated with clinical treatment, while those in control group were treated with conventional nursing and observation group combined with early rehabilitation nursing intervention. Echocardiogram, 6 min walking test (6MWT), body composition analyzer (measuring extracellular moisture ratio) and body mass index (BMI) was used to evaluate the changes of all indexes before and after nursing care in 2 groups.@*Results@#Using the receiver operating characteristic curve(ROC) of extracellular moisture ratio to predict heart failure, the area under the curve (AUC) of patients with heart failure was predicted to be 0.737(P<0.01). Analysis of the correlation between the decrease of extracellular moisture ratio after treatment and the increase of walking distance after 6 minutes of treatment showed a positive correlation. With the decrease of extracellular water ratio after treatment, the 6MWT distance increased continuously after treatment (r=0.164, P=0.032). In the observation group, the 6 minute walking distance, extracellular water ratio, the added value of BMI, added value of 6 minute walking distance after treatment, after treatment of extracellular water reducing ratio, and BMI lower values were (438.76±89.16) m, (0.380±0.021)%, (24.74±3.13) kg/m2, (129.20±18.62) m, 0.010±0.006, (2.71±0.89) kg/m2, respectively. The control group were (356.40±85.28) m, (0.384±0.014)%, (25.93±2.68) kg/m2, (60.25±8.43) m, 0.009±0.008, (1.37±0.85) kg/m2. The differences between the two groups were statistically significant (t=1.726-15.739, P<0.05).@*Conclusions@#The extracellular moisture ratio indicates the degree of heart failure. Clinical treatment combined with early rehabilitation nursing intervention is superior to conventional nursing in patients with heart failure, which can significantly increase the patient′s 6MWT and reduce the patient′s BMI, which is worth popularizing and applying.
ABSTRACT
O objetivo do presente trabalho foi avaliar a cinética de secagem das folhas de erva baleeira (Cordia verbenacea DC.) bem como ajustar diferentes modelos matemáticos aos valores experimentais de razão de umidade. As folhas de erva baleeira foram colhidas com teor de água inicial de 75% b.u., sendo submetidas à secagem sob condições controladas de temperatura (40, 50, 60 e 70°C), até o teor de água aproximado de 10% b.u.. Aos dados experimentais foram ajustados oito modelos matemáticos citados na literatura específica e utilizados para a representação do processo de secagem de produtos agrícolas. Com base nos resultados obtidos pôde-se concluir que o modelo de Midilli é o que melhor representa a cinética de secagem das folhas de erva baleeira. O aumento da temperatura do ar de secagem promoveu maior taxa de remoção de água do produto. O coeficiente de difusão efetivo aumenta com a elevação da temperatura, sendo que sua relação com a temperatura de secagem pode ser descrita pela equação de Arrhenius. A energia de ativação para a difusão líquida durante a secagem das folhas de erva baleeira foi de 62,89 kJ mol-1 .
The objective of the present work was to evaluate the drying kinetics of Cordia verbanacea DC. leaves, as well to fit different mathematical models to the experimental data of the moisture ratio. The Cordia verbanacea Dc. leaves wers harvested with initial moisture content of approximately 75% w.b. and submitted to the drying process under controlled conditions of temperature (40, 50 60 and 70ºC), until the approximate moisture content of 10% w.b. Eight mathematical models mentioned or the specific literature were fitted to the experimental data and used to predict the drying process of the agricultural products. Based on the results obtained,swe have concluded that the Midilli model was the one that best represents the drying kinetics of Cordia verbanacea leaves. The temperature increase of the drying air promotes higher removal rate of water from the product. The effective diffusion coefficient increases with temperature elevation,tand its relationship with the drying temperature can be described through the Arrhenius equation, which presents activation energy of 62.89 kJ mol-1 for the liquid diffusion during the drying of the Cordia verbanacea DC. leaves.
