Objective To assess the changes of the cardiac function of the patients with myocardial infarction(MI) after the coronary revascularization(CRV) by 2D echocardiography and Doppler tissue imaging(DTI).The effects of CRV on cardiac function were explored.Methods The global and regional wall functions were quantitatively analyzed in 49 patients with MI by 2D echocardiography and DTI(Aspen imaging systems).Results The regional function was improved prior to the global function in patients with MI after successful CRV.Conclusions CRV is one of the important factors for the cardiac function improvement in patients with MI.

0.05).Both of them had a linear correlativity,correlative coefficient closed to 1.Conclusions Coronary artery endothelial function and brachial artery endothelial function had a high linear correlativity.
3.STUDY ON THE LEFT VENTRICULAR DIASTOLIC FUNCTION IN PATIENTS WITH MILD AND MODERATE HYPERTENSION
Medical Journal of Chinese People's Liberation Army 1983;0(02):-
To evaluate the left ventricular diastolic function with Doppler and 2D echocardiography in patients with mild and moderate hypertension. 202 patients with hypertension were involved in this study. The parameters of Doppler and 2D echocardiography were compared with clinical materials of the patients. The results of this study showed that age, diabetes, left ventricle hypertrophy and duration of hypertension were related to the left ventricular diastolic function, whereas hyperlipidmia, smoking and alcohol drink had less effect on left diastolic function. The results of this study suggested that there were diastolic dysfunction in patients with hypertension, and Doppler and 2D echocardiography could be used to detect left ventricular diastolic function.
5.Comparison dominant eye and anisometropia by Worth 4 dot test and hole-in-the-card test
International Eye Science 2014;(8):1476-1477
ATM: To investigate the relationship between the oculus dominans and the eye with higher diopter among myopes, and to study the difference between the Worth 4 dot test and hole-in-the-card test.
METHODS: Totally 125 cases were divided into two groups as physiogenic anisometropic group and pathological anisomitropic group according to the degree of binoculus anisometropy. Worth 4 dot test and hole-in-the-card test were used to distinguish oculus dominans respectively based on medical optometry.
RESULTS: In physiogenic anisometropic group, the oculus dominans and the eye with higher diopter among myopes had significant relationship by hole-in-the-card test (Z = -4. 057, P<0. 01) and Worth 4 dot test (Z=-3. 558, P<0. 01). However, in pathological group, No statistical significance was between two tests (P>0. 05); distinguish the oculus dominans had no statistically significant difference between the Worth 4 dot test and hole-in-the-card test (n=125, P>0. 05).
CONCLUSION:The oculus dominans is determined by gene or formed during juvenile period, then myopia anisometropic may affect the choice of that. The Worth 4 dot test has some reference significance for observing oculus dominans.

Objective To assess left ventricular systolic and diastolic function in patients with hypertrophic cardiomyopathy(HCM) with the aid of pulsed Doppler tissue imaging (DTI) to measure the four sides of mitral annular. Methods Thirty subjects with HCM and Twenty five age and sex matched controls were performed 2D and Doppler echocardiography . Two groups were studied with pulsed tissue Doppler imaging of the 4 sides of the mitral annulus (septal, lateral, inferior, anterior) in 4 and 2 chamber views. The velocities of systolic wave(Sa)、early diastolic filling wave (Ea)、late filling wave (Aa) and isovolumetric relaxation time were measured by DTI. Results Compared with normal control group, HCM group shows: (1) conventional data: LV wall thickness and mass indices were significantly greater. There were no significant difference in mitral flow Velocity. (2) DTI: There were more lower velocities of systolic and early diastolic filling wave. But isovolumetric relaxation time、mitra flow velocity / mitral annual early diastolic velocity ratio(E/Ea) increased. The velocities of systolic and early diastolic of septal site were the lowest among the 4 sides of the mitral annular and were the most closely with the average velocities of systolic and early diastolic of mitral annual. In addition, DTI may detect the pseudonormalization of mitral inflow. Conclusions DTI is more sensitive than conventional echocardiogram data and may be clinically used in exactly detecting left ventricular systolic and diastolic dysfunction in patients with HCM
