Objective To further recognize the coronary artery three vessel disease by studying the abnormal change of the electrocardiogram(ECG)and echocardiography of ischemic heart disease patients and unstable angina pectoris patients,and to analyze the results of coronary angiography.Methods Coronary arteriography for 2 654 patients diagnosed as ischemic heart disease,unstable angina pectoris,were conducted and the result of coronary arteriography were compared with the ECG and echocardiography.Results There were certain statistically significant correlation among the ECG,echocardiography abnormal change and three vessel coronary artery disease(ECG:χ2 =9.02,P <0.01;echocardiography:χ2 =14.36,P <0.01).The sensitivity,specificity,false positive rate,and false negative rate of ECG were 71.46%,27.47%,62.26% and 28.50% respectively.The sensitivity,specificity,false positive rate, and false negative rate of echocardiography were 61.27%,27.08%,72.91% and 38.72% respectively.ECG′s change of patients appear in 8 or more leads when angina pectoris attacks exist,the incidence of chest lead terminal positive T wave were higher than 90.00%.Ⅲ lead fQRS wave group or low voltage changeed and AVR lead ST seg-ment elevation were accounting for 82.61% and 56.52% respectively.Conclusion There are certain correlation and predictive value among the ECG,echocardiography and three vessel coronary artery disease.There are characteristic waveform change of ECG when angina pectoris attacks exist.

Objective To compare the cardiac function parameters in gated SPECT determined by filtered back projection (FBP) and OSEM reconstruction methods. Methods One hundred and forty-four patients underwent 99Tcm-MIBI gated-SPECT imaging studies. The parameters LVEF, EDV and ESV, were derived using quantitative gated SPECT (QGS), four-dimensional model SPECT (4D-MSPECT) and emory cardiac toolbox (ECToolbox) softwares. Each image was reconstructed by FBP or OSEM. Bland-Altman analysis and paired t-test were applied to evaluate those parameters. Results Correlation coefficients for LVEF, EDV and ESV between FBP and OSEM methods were all more than 0.93 (all P<0.001). EDV calculated by FBP was lower than that by OSEM using QGS software, but became the opposite when using 4D-MSPECT and ECToolbox softwares. (QGS: (82.2±39.1) ml vs (83.5±40.8) ml, t=-2.53, P<0.05; 4D-MSPECT: (93.5±46.9) ml vs (88.8±45.2) ml, t=5.95, P<0.01; ECToolbox: (106.4±51.1) ml vs (100.8±49.0) ml, t=3.99, P<0.01). ESV calculated by FBP was higher than that by OSEM using 4D-MSPECT software (4D-MSPECT:(37.5±41.4) ml vs (34.8±37.6) ml, t=3.92, P<0.01). LVEF calculated by FBP was lower than that by OSEM using QGS software ((62.1±16.9)% vs (63.1±16.1)%, t=-3.14, P<0.05), but higher than that by OSEM using ECToolbox software ((74.1±18.8)% vs (71.3±17.1)%, t=5.28, P<0.01). Conclusion Generally, cardiac functional parameters based on FBP and OSEM construction methods correlated well, although they might have singnificantly different results.

Objective:To explore the application and nursing of protein A immunosorbent in patients with neuromyelitis optica spectrum diseases.Methods:Ten patients with neuromyelitis optica spectrum diseases were treated with protein A immunoadsorption therapy. Psychological nursing was emphasized. Comprehensive evaluation was conducted before adsorption to determine the prescription of adsorption therapy. During adsorption therapy, hypotension, membrane rupture and hemolysis of plasma separator, shivering and other adverse reactions were accurately prevented and treated. After treatment, attention should be paid to the prevention of nosocomial infection, regeneration and preservation of adsorption column.Results:After immunoadsorption therapy, the serum IgG level, antibody and EDSS score of 10 patients decreased to varying degrees. The serum IgG decreased from (6.04±2.77)g/L to (2.23±1.74)g/L. No serious complications occurred, no failure of immunosorbent operation, and the patients′ condition was better than before.Conclusions:Protein A immunosorbent therapy for neuromyelitis optica spectrum diseases is safe and effective. Standardized evaluation, operation and nursing are the key to achieve good results.

Objective To evaluate the feasibility and effect of transthoracic echocardiography(TTE)on guiding the occlusion of the soft-rim atrial septal defect(ASD).Methods Sixty two patients with the soft-rim ASD were enrolled.The size of ASD was measured and rim of ASD was observed by TTE on various views by using color Doppler system with tissue harmonic function before occlusion,and filmy rim of ASD with flapping which could not sustain occluder was eliminated.The size of occluder was selected by integratively judging the size of ASD and"sustainable diameter of ASD"The waist size of occluder was measured after releasing occluder and compared with the longest diameter of ASD and"sustainable diameter of ASD"measured by TTE.Results The longest diameter of ASD measured by TTE before occlusion was 11-35 mm[average(21.6±5.2)mm],the "sustainable diameter of ASD"was 15-37 mm[average(25.6±5.(J)mm],the size of selected occluder was 18-44mm[average(30.7±5.5)mini and the waist size of released occluder was 13-35 mm[average(24.2±5.6)mm].Fine correlation was existed between the longest diameter of ASD measured by TTE and the waist size of released occluder(r=0.86,P＜0.000I).Morever,improved correlation was found between the"sustainable diameter of ASD"measured by TTE and the waist size of released occluder(r=0.89,P＜0.0001).Occluder was firmly fixed without falling in all patients.Conclusions TTE with tissue harmonic function can be used to measure the size of soft-rim ASD and the"sustainable diameter of ASD".It is a feasible,and effective method on guiding occlusion of soft-rim ASD.

Objective To study the relationships among resilience, self-awareness, personality, stress level and mental health in the warship soldiers. Methods Resilience Scale for Adults ( RSA), Eysenck Personality Questionnaire ( EPQ), Self Acceptance Questionnaire( SAQ), General Self-Efficacy Scale( GSES), Wallance Self Concept Scale (WSCS), Psychological Stress Self-evaluation Test (PSET) and Symptom Checklist (SCL-90)were used to survey 1451 warship soldiers. Results ① 2.5％ of the warship soldiers reported obvious psychological stress. Mental health of warship soldiers was worse than the norm of China population, except for obsessivecompulsive and interpersonal sensitivity factor. While the scores of other factors were significantly higher than the norm of Chinese soldiers(P＜0.01). ②The total scores of SCL-90, psychological stress and resilience, internal/external had negative correlation with self-awareness, and positive correlation with neuroticism. Compared to the SCL-90-negative group,SCL-90-positive soldiers (SCL-90 total score ＞ 160) had higher scores of nervousness and PSET and lower scores of RSA, internal/external and self-awareness (P ＜ 0.01 ). ③Regression analysis showed that stress levels, emotional stability,self-awareness and resilience were able to predict 35.1％ of mental health in warship soldiers. Mental health, emotional stability, internal/external and resilience were able to predict 33.2％of individual's stress level. Conclusion To some extent, warship soldiers have psychological stress and mental health problems. Resilience, personality, self-awareness are important factors affecting psychological stress and mental health.
