Objective To evaluate the accuracy of coronary flow velocity reserve(CFVR) measured by color Doppler coronary flow imaging(CFI) in the patients with myocardial bridging(MB) of the left anterior descending (LAD) coronary artery and to analyze coronary hemodynamic changes and clinical significance of the LAD MB. Methods Consecutive 110 patients with suspected or known coronary disease were examinated by coronary angiography(CA), coronary intravascular ultrasound(IVUS) and intracoronary Doppler(ICD). Of these patients, 11 cases were diagnosed as MB of LAD. The LAD flow were measured by CFI at baseline and hyperemic conditions (intravenous administration of adenosine 140 μg·kg-·min-)and CFVR were calculated. Compared with the measurements of ICD, the accuracy of CFI was analyzed. Nine normal cases served as control group. Results The prevalence of MB was 10% in this study. Seven eases presented with stable angina. MB located in the middle segment of LAD in 7 cases and in the middle-distal segment of LAD in 2 cases. The ratio of LAD stenosis was greater than 80% in 2 cases, one of them simultaneously combined with circumflex stenosis(90 %). CA showed no significant stenosis in 9 cases (MB group) in the LAD and IVUS showed no plaque. Flow velocities were measured by CFI in the middle-distal LAD in nine patients without significant stenosis. CFVR calculated by average peak velocity well correlated with those measured by ICD (regression equation: Y=0.87 X+0.39; correlation coefficient: r=0.81,P<0.01). The coronary flow velocities in hyperemic conditions were significantly lower in MB group than in control group. CFVR were also significantly lower in MB group than in control group. Conclusions CFI is an accurate method for assessment of CFVR. Decreased CFVR of patients with MB may be one of the causes of angina pectoris.

Sleep and memory are the basic function of the brain. A large number of studies from both humans and animals experiments have offered a substantive body of evidence supporting that sleep contributes crucially to memory consolidation. The processes of memory consolidation in hippocampus and cortex during sleep was reviewed and the primary cellular and molecular mechanism were briefly introduced.

It is well believed that learning and memory is one of the functions of sleep.Not only does the sleep after learning aid memory consolidation, but enough sleep before learning is necessary for memory formation.Due to the net increase in synaptic strength, waking plasticity has a cost in terms of energy requirements, space requirements, and progressively saturates the capacity to learning.The review will focus on the role of sleep which is to downscale synaptic strength to a baseline level that is beneficial for learning and memory.

Objective To assess global and regional cardiac twist function in hypertrophic cardiomyopathy(HCM) patients by velocity vector imaging(VVl).Methods Thirty HCM patients and 33 normal subjects were enrolled into this study.Two dimensional echocardiographic images of parasternal left ventricular basal level,middle and apical level short axis plane,apical four-and two-chamber plane were obtained.Maximal rotation degree,peak rotation rate,circumferential strain (CS) and strain rate (CSR),radial strain(RS) and strain rate(RSR) in systole were measured using VVI offline software.In addition,diastolic peak un-rotation rate,untwisting rate(unTwR) were measured.Each parameters was analyzed both in subendocardial and subepicardial layer.Results There was no significant difference in left ventricular ejection fraction between two groups.EDV,ESV,SV were significantly decreased (P＜0.01) in HCM group.Left ventricular twist(LVtw),CS of subendocardial layer were higher in HCM group than control group(P＜0.05),while the peak rotation rate,un-rotation rate,CS,CSR were lower of subepicardial layer (P＜0.05).The RSR of each short axis level were significantly decreased in HCM group (P＜0.01).The diastolic unTwR was decreased in HCM group (P＜0.05).For further analysis of the two subgroups in HCM,more regional torsion deterioration occurred in patients with left ventricular outflow tract obstruction than those without obstruction.Conclusions The global cardiac twist angle of HCM was higher than normal person,but the circumferential deformation ability of regional myocardium was impaired,left ventricular outflow tract obstruction may aggravate the regional myocardial dysfunction.

Objective To validate the measurement of coronary flow velocity and coronary flow velocity reserve(CFVR) by transthoracic Doppler echocardiography(TTDE) compared with invasive intracoronary Doppler flow wire technique(ICD) and to evaluate changes in coronary flow dynamics due to microvascular dysfunction in the patients with angiographically normal coronary arteries and chest pain.Methods Coronary flow velocity was measured in the distal left anterior descending artery(LAD) in 35 patients by TTDE at baseline and during intravenous adenosine infusion of 140 ?g?kg -1 ?min -1 . CFVR, coronary vascular resistance(CVR) and minimal coronary vascular resistance index(CVRI) were analysed in the patients with angiographically normal coronary arteries and chest pain (group A, n =20) and compared to a control group (group B, n =15).Results Average peak velocity at baseline (APVb),average peak velocity at hyperemia (APVh) and CFVR determined from TTDE correlated closely with those from ICD measurements.CFVR was lower and CVRI was higher in group A than in group B.Conclusions Noninvasive TTDE provides reliable measurement of coronary flow velocity and CFVR in the distal LAD.Microvascular dysfunction existed in the patients with normal angiograms and chest pain.

Objective To evaluate the cardiovascular stiffness and its coupling of patients with hypertension by ultrasound.Methods Fifty patients with essential hypertension and 30 age- and gendermatched subjects without hypertension,diabetes and other cardiovascular diseases as control group were enrolled in this study.The parameters of structure and function of left ventricle,blood flow were measured by echocardiography.The blood pressure and carotid-femoral pulse wave velocity (CFPWV) were also measured.The derived corresponding parameter:end-systolic pressure(ESP),effective arterial elastance (Ea),end-diastolic (Ed),end-systolic ventricular elastance (Ees) and Ea/ Ees were calculated respectively.Results Ees was correlated positively with ejection fraction (r =0.378,P =0.005),while Ea was correlated positively with CFPWV( r =0.289,P ＜0.001).Ed was correlated negatively with e/a ( r =- 0.333,P =0.027).Posterior wall of left ventricle was correlated positively with Ed and Ea( r =0.388,P =0.016; r =0.336,P =0.026).Ea and Ed in patients with hypertension were significantly higher than those in control group( P ＜0.05),but there was no significant difference of Ees and Ea/ Ees between two groups( P ＞ 0.05).Conclusions Arterial stiffness is associated with ventricular stiffness,and their matching relation can be applied to evaluate ventricular-arterial coupling.

Objective To study the clinial application value of MR dispersion arthrography in meniscus tear of knee.Methods The conventional MR scans of 24 knee joints in 24 patients who were considered to have meniscus tear were performed and followed by MR dispersion arthrography.All cases were approved by arthroscope or operation.The results of both convention MR scan and MR arthrography were compared with arthroscope and operation.The sensitivity and the specificity of plain MR scan and MR dispersion scan were evaluated respectively.Results The signal intensity in the area of meniscus tear was obiously highen on MR dispersion scan than that of MR plain scan.The sensitivity was improved from 74.2% to 94.3% ,and the specificity improved from 88% to 94.3%.Conclusion MR dispersion scan is superior to convention MR scan in image quality and sensitivity in detecting meniscus tear.

Objective To non-invasive assess coronary blood flow velocity changes of patients with slow coronary flow phenomenon (SCFP) by coronary blood flow imaging (CFI).MethodsTwenty-one patients who had no significant coronary artery stenosis but had thrombolysis in myocardial infarction (TIMI) slow-flow phenomenon were the experimental group,nine patients who has no significant coronary stenosis and TIMI flow normal were the control group.Using corrected TIMI frame count(CTFC) assess velocity of coronary artery.The left ventricular end diastolic diameter,end systolic diameter,ejection fraction,E peak velocity,A peak velocity,E/A ratio were measured by conventional echocardiography.The distal anterior descending coronary artery diastolic peak flow velocity(Vmax),mean velocity(Vmean) and blood flow velocity time integral(VTI) were measured by CFI.Results The corrected TIMI frame count (CTFC) of left anterior descending artery blood flow in slow blood group was (45.37 ± 8.62)frame,that in control group was (15.94± 4.66)frame,the difference was statistically significant (t = -9.596,P =0.000).The conventional echocardiographic measurements of two groups were not significantly different.The left anterior descending artery Vmax was (22.86 ± 3.04)cm/s,Vmean was (17.62 ± 2.89)cm/s,VTIwas (8.49± 2.01)cm in the slow blood flow group,the left anterior descending artery Vmax was (31.78 ± 9.28) cm/s,Vmean was (23.67 ± 7.60) cm/s,VTI was (10.91 ± 4.47) cm in the control group.The difference was statistically significant.The left anterior descending artery CTFC with Vmax and Vmean was negative correlation in the control group and the slow blood flow group.The left anterior descending artery CTFC was negatively correlated with VTI in the control group,there was no correlation between left anterior descending artery CTFC and VTI in the slow blood flow group.Conclusions Coronary artery flow velocity in the left anterior descending artery was declined.CFI can reflect changes in coronary TIMI flow,but in the diagnosis of coronary slow flow phenomenon CFI has limitations.
