ABSTRACT
Objective To detect the change and clinical significance of homocysteine (Hcy),hypersensitivity C response protein (hs-CRP) and hypersensitivity troponin I (hs-TnI) in patients with acute myocardial infarction (AMI).Methods Ninety-six cases of AMI were selected as the research group and 60 cases of coronary heart disease without AMI were enrolled in the control group.Blood samples were collected to measure the contents of serum Hcy,hs-CRP and hs-TnI.ROC curve was drawn and Logistic regression model was established to analyze the role of each index alone and combined detection in the diagnosis of AMI.Results The levels of Hcy,hs-CRP and hs-TnI in the research group were significantly higher than those in the control group (Hcy: (29.29±7.65) mol/L vs.(17.23±4.68) mol/L;hs-CRP: (15.47±5.01) mg/L vs.(9.21±3.15) mg/L;hs-TnI: (40.88±9.18) ng/mL vs.(7.34±2.12) ng/mL,t=2.78,8.66,34.36,P<0.05).The area under the ROC curve of Hcy,hs-CRP,hs-TnI were 0.802 (95%CI(0.729~0.874)),0.71(95%CI(0.62~0.792)),0.929 (95%CI(0.891~0.967)),respectively.The area under the combine detection curve was 0.971 (95%CI,0.950~0.992).The sensitivity of Hcy,hs-CRP and hs-TnI in the diagnosis of AMI were 79%,57%,87%,respectively,the specificity of the three groups were 72%,70%,90%,the sensitivity and specificity of combined detection were 96% and 88%.Conclusion Combined detection of Hcy,hs-CRP and hs-TnI plays a better role in the diagnosis of AMI than that of Hcy,hs-CRP,hs-TnI alone and has a high specificity and sensitivity in the diagnosis of AMI.
ABSTRACT
Objective:To explore influence of nursing intervention according to comprehensive geriatric assessment (CGA)on quality of life (QOL)in aged patients With coronary heart disease (CHD).Methods:A total of 96 aged CHD inpatients admitted in department of cardiology from Mar 2012 to Mar 2013 Were enrolled.According to num-ber table method,they Were randomly divided into routine nursing group (n=48,received specific nursing of cardi-ology department)and CGA group (n=48,received nursing intervention according to CGA based on routine nurs-ing).Chinese questionnaire of quality of life in patients With cardiovascular disease (CQQC)Was used to score and compare each dimension of QOL betWeen tWo groups at admission and on 6-month after discharge.Results:Com-pared With routine nursing group after intervention,there Were significant increase in scores of physical strength [(7.35±4.12)scores vs.(10.86±5.06)scores],patient's condition [(4.57±0.85)scores vs. (8.75±4.54) scores],medical condition [(4.72±0.82)scores vs.(5.90±0.40)scores],general living [(3.85±1.45)scores vs. (5.22±1.95)scores],social psychological conditions [(3.67±1.52)scores vs.(8.41±3.22)scores],Working sta-tus [(0.70±0.64)scores vs.(0.97±0.66)scores]and total score of CQQC [(24.86±4.43)scores vs.(40.11± 9.05)scores]in CGA group,P<0.01 or<0.05.Conclusion:Nursing intervention according to comprehensive geri-atric assessment can improve quality of life in aged patients With coronary heart disease.
ABSTRACT
Objective This research aimed to investigate the function mechanism of lung injury after acute pulmonary embolism.Methods 30 healthy New Zealand rabbits were selected and randomly divided into five groups:control group (with venepuncture applied) and model groups including none-saline (NS) control group,exogenos laptin low doses group,medium dose group and high dose group.ELISA was applied to examine the TNF-αand IL-1β in serum.Results TNF-α and IL-1β content in saline group were higher than that in control group,and the results were statistically significant.In medium dose (50 μg/kg) group,TNF-α and IL-1β levels decreased apparently and the results were statistically significant.In low doses (20 μg/kg) group,TNF-α and IL-1β levels decreased,but the results were not statistically significant.In high dose (100 μg/kg) group,TNF-α and IL-1β levels increased on the contrary.Conclusion Suitable dose of leptin will lead the decrease of postoperative levels of TNF-α and IL-1β after acute pulmonary embolism,which thus have protection function to the injured lung.
ABSTRACT
OBJECTIVE:To study the efficacy of Urokinase vs.Low Molecular Weight Heparin in the treatment of acute pulmonary thromboembolism.METHODS:A total of 35 patients with acute pulmonary thromboembolism who had no past history of heart and lung diseases were enrolled and randomly assigned to two groups following ultrasonography and pulmonary ventilation/perfusion scanning:15 were given thrombolysis therapy with urokinase,and 20 given anticoagulation therapy with low molecular weight heparin.Symptoms,arterial blood gas analysis,electrocardiogram,echocardiogram were compared in two groups before and after treatment.RESULTS:The patients receiving thrombolysis therapy had better improvement in symptoms,arterial blood gas index,echocardiogram and the pulmonary ventilation/perfusion scanning than in those receiving anticoagulation therapy(P
