  • Antithrombotic Therapy for Gerontal Patients with Atrial Fibrillation and Coronary Artery Disease: Evidence-Based Practice

    ObjectiveTo retrieve currently-available best evidence to select the treatment plan of antithrombotic therapy for a gerontal patient lately admitted because of atrial fibrillation (AF) and coronary artery disease (CAD), and to provide references for clinical treatment. MethodsWe comprehensively searched PubMed, MEDLINE (Ovid), EMbase and The Cochrane Library (Issue 5, 2014) up to May 2014, for relevant evidence about antithrombotic therapy for patients with AF and CAD. After analysis and assessment, we developed the plan of the patient's antithrombotic therapy. ResultsCurrent evidence showed no best treatment plan of antithrombotic therapy for patients with AF and CAD. ConclusionCorrect evaluation of the risks of thrombosis and bleeding is the key point of beneficial antithrombotic therapy for patients with AF and CAD.

  • Evidence-Based Diagnosis for an Elderly Patient with Hematuria

    ObjectiveTo determine the diagnosis method for an elderly male patient with hematuria by means of evidence-based practice, so as to provide references for clinical diagnosis. MethodWe searched databases including PubMed, EMbase, and The Cochrane Library up to Nov. 2014, to collect relevant diagnostic evidence for elderly patients with hematuria. ResultsCompared with MRI, CT had higher sensitivity and specificity in determination of lesion location in where the hematuria was caused by tumor. ConclusionsCT scan may be better for patients with hematuria to determine the location of lesion.

  • Effects of Normalization Management on Prognosis in Elderly Patients with Coronary Artery Disease

    Objective To evaluate the efficacy of normalization management on prognosis in elderly patients with coronary artery disease, in aspects of drug compliance, readmission rate and quality of life. Methods A total of 110 patients above 65 years old with coronary artery disease visiting West China Hospital from August 2010 to February 2011 were investigated. The patients were divided into two groups: the intensive management group (n=55) and the general management group (n=55). The measures such as regular follow-up, regular examination and medical education were conducted in the intensive management group, and the two groups were observed in aspects of drug compliance, readmission rate and quality of life. Results After 1-year follow-up, the percentages of patients taking aspirin/clopidogrel (98.18% vs. 67.27%, Plt;0.05), nitrate (85.45% vs. 40.00%, Plt;0.05), ACEI/ARB (56.36% vs. 18.18%, Plt;0.05), β receptor blocker (58.18% vs. 29.09%, Plt;0.05) and statin (94.55% vs. 32.73%, Plt;0.05) were higher in the intensive management group than those in the general management group. Also, the readmission rate was lower (12.73% vs. 41.42%, Plt;0.05) and the score of quality of life was higher in the intensive management group than that in the general management group. Conclusion The normalization management guided by evidence-based medicine for the elderly patients with coronary artery disease is helpful to improve the drug compliance, reduce the readmission rate, and improve the quality of life.

  • Rehabilitation for the elderly in the aging society

    In order to solve the predicament brought by the aging society, China has promoted the combination of medical care. Hence, rehabilitation for the elderly may become a new strategy for the development of rehabilitation. According to the development of three different models and situation of China, we focus on improving the function of the elderly based on the families, the communities and institutions. Finally, the elderly feel happy and respected by getting professional means of rehabilitation while aging. The insurance system is the guarantee of promoting rehabilitation for the elderly and the " ternary theory” rehabilitation theory should be the guide concept. In the future, the trend is to build China’s three-level " intelligent rehabilitation for the elderly system” by artificial intelligence and big data cloud platform.

  • Electrocardiogram signal classification algorithm of nested long short-term memory network based on focal loss function

    Electrocardiogram (ECG) can visually reflect the physiological electrical activity of human heart, which is important in the field of arrhythmia detection and classification. To address the negative effect of label imbalance in ECG data on arrhythmia classification, this paper proposes a nested long short-term memory network (NLSTM) model for unbalanced ECG signal classification. The NLSTM is built to learn and memorize the temporal characteristics in complex signals, and the focal loss function is used to reduce the weights of easily identifiable samples. Then the residual attention mechanism is used to modify the assigned weights according to the importance of sample characteristic to solve the sample imbalance problem. Then the synthetic minority over-sampling technique is used to perform a simple manual oversampling process on the Massachusetts institute of technology and Beth Israel hospital arrhythmia (MIT-BIH-AR) database to further increase the classification accuracy of the model. Finally, the MIT-BIH arrhythmia database is applied to experimentally verify the above algorithms. The experimental results show that the proposed method can effectively solve the issues of imbalanced samples and unremarkable features in ECG signals, and the overall accuracy of the model reaches 98.34%. It also significantly improves the recognition and classification of minority samples and has provided a new feasible method for ECG-assisted diagnosis, which has practical application significance.

  • Effects of Exogenous Nerve Growth Factor on Late Reperfusion after Myocardial Infarction

    This study demonstrates that nerve growth factor (NGF) plays a protective role in myocardial infarction and early reperfusion by reducing the myocardial cell apoptosis and by improving ventricular remodeling and seeks to assess the effects and mechanisms of NGF on late reperfusion after myocardial infarction. The models of late reperfusion were established by ligating the left main coronary artery and then cutting the suture 2 hours after coronary artery ligation. The rats in NGF treatment group were injected 10μL Ad-NGF (by constructing the adenovirus vector Ad-NGF containing NGF gene) at four locations around infarction. The rats in adenoviral vector (Adv) group were injected 10μL adenoviral cector as the NGF group. The late reperfusion group and the sham group were given normal saline as above, and the sham group underwent thracotomy without coronary ligation. On the 3rd, 7th, 14th and 28th day after operation, we investigated the role of NGF on late reperfusion by recording cardiac structure and function with echocardiography, by examining the expression of NGF andⅧfactor with immunohistochemical method, and by evaluating the myocardial cell apoptosis with terminal dUTP nick end-labeling method (TUNEL). We found that the NGF group had higher expression of NGF protein (P < 0.01) and lower apoptosis index (AI) (P < 0.01 or P < 0.05) compared to the late reperfusion group and Adv group on all time points. The NGF group had remarkably higher level of neovascularization compared to the late reperfusion group on the 14th day (P < 0.01) and the 28th day (P < 0.05). The NGF group also had higher LVEF and FS levels compared to the late reperfusion group on the 14th day (P=0.006, P=0.006) and on the 28th day (P=0.000, P=0.000). Whereas the NGF group had lower LVEDD, LVESD (P=0.038, P=0.000) and lower LVEDV, LVESV (P=0.001, P=0.000) on the 28th day compared to late reperfusion group. In this experiment, the NGF gene carried by adenovirus vector had been trans-fected and obviously increased the expression of NGF protein in NGF group. NGF may help postpone the myocardial remodeling and improve the heart function by promoting the myocardial neovascularization and inhibiting myocardial apoptosis.
