Objective To assess the application of automated four-dimensional (4D) volume color Doppler ultrasonography in normal fetal heart screening. Methods Four-dimensional volume color Doppler was acquired at the level of four chamber view level in 120 fetuses from 18 to 23 weeks of gestation. Three diagnostic planes including color Doppler information were retrieved by automated multiplanar imaging from the 4D volumes. The left ventricular outflow view (cardiac plane 1), the right ventricular outflow view (cardiac plane 2) and ductal arch view (cardiac plane 3) were acquired. Tomographic ultrasound imaging (TUI) was added to display all the three diagnostic planes. The data were then analyzed to determine whether cardiac planes 1-3 were displayed correctly in each volume. Results Automated 4D volume color Doppler ultrasonography displaying rate of cardiac plane 1, cardiac plane 2, cardiac plane 3 were 100%, 96.67% and 91.67%, respectively. Cardiac plane 1 was displayed at least three TUI plane, cardiac plane 2 was displayed at least two TUI plane, and cardiac plane 3 was displayed at least two TUI plane. Conclusion It is possible to acquire important planes of the fetal heart with automated 4D volume color Doppler ultrasonography and the visualization rate of the three diagnostic planes is fine.

Objective To assess the application value of real time three-dimensional (RT-3D) ultrasonography in diagnosis of fetal corrected transposition of the great arties (cTGA). Methods Data of 14 fetuses diagnosed as cTGA clinically were reviewed. With 2D ultrasonography, diagnosis views were obtained and then studied using cardiac three-section analytic method. With real time 3D (RT-3D) ultrasonography, volume datasets were acquired at the level of four chamber view, and spatio-temporal image correlation (STIC) was then used to analyze the relationship of the two great arties. Confirmed by infant echocardiography and the autopsy findings, the accuracy of RT-3D and 2D ultrasonography in evaluation of fetal cTGA and complications were compared. Results The accuracy rate of RT-3D and 2D ultrasonography in diagnosis of fetal cTGA was 92.86% and 71.43% (χ~2=2.19, P=0.14). The procedure time of RT-3D ultrasonography was significantly shorter than that of 2D ultrasonography (t=10.23, P<0.001). Conclusion RT-3D ultrasonography can evaluate fetal cTGA and its complications more quickly and exactly than conventional 2D ultrasonography.

Objective To investigate cross-cultural differences in picture recognition memory of medical students. Methods Picture recognition memory were assessed by the classic new-old picture recognition,and behavioral results were recorded during the test. Results For new medical picture recognition, mean accuracy of Chinese medical students( 83.21 ± 8.95 )% was considerably higher than that of Indian medical students( 75.56 ±12.63)% (P<0.05), while for old medical picture recognition, reaction time (RT) of Chinese medical students ( ( 887.57 ± 104.07 ) ms ) was longer than that of Indian medical students ( ( 840.93 ± 1 22.48 ) ms) (P<0.05).Three way ANOVA suggested that cultural background and picture type significantly affected accuracy and RT,learning experience affected RT. In addition to picture type and learning experience, the interaction of each factors is not remarkable. Conclusion Cultural background, professional background and learning experiences have affected recognition memory. Medical students of different cultural background adopted difference strategies in picture recognition memory.

Objective To discuss the method and skill of prenatal diagnosis of fetal isolated pulmonary stenosis and thus to improve prenatal diagnostic ability. Methods The data of 18 fetuses diagnosed as isolated pulmonary stenois were reviewed and the ultrasonic characters of each section were analysised. Results Five of the 18 cases were confirmed as pulmonary stenosis by autopsy and 12 cases were confirmed by echocardiography after birth. One case was confirmed as pulmonary atresia by echocardiography after birth. Reversed blood flow in arterial duct was detected at the ductal arch section in all the cases and right atrial enlargement,right ventricular myocardial hypertrophy, tricuspid regurgitation, foramen ovale enlargement, reduced activity of foramen ovale valve were detected in partial cases. Conclusions It is important that reversed blood flow in arterial duct and in the two main artery could be observed at the ductal arch section and the three vessel section respectively. Ductal arch section,ventricular outflow tracts section and the three vessel section are very important in the diagnosis of fetal isolated pulmonary stenosis.

Objective To compare the event-related potential(ERP) difference waveforms between attention deficit hyperactivity disorder (ADHD) children and normal children in the conflict task,and to investigate the neural mechanism of conflict monitoring of ADHD. Methods ERPs elicited by performing the spatial SimonStroop task were recorded in 32 children with ADHD and 32 normal children. The differences of ERP and behavior dren with ADHD(0.80±0. 11 ,0.87 ±0.08) were less than normal children (0.88 ±0.07,0.93 ±0. 04)in Sireaction time of ADHD group( (773.03 ±99.34)ms) in the Siin were longer than the control group( (737.21 ±81.40)ms) ,the differences had statistic significance (P<0. 05). 2. ERP results:the amplitude of N2 of the children with ADHD in the four conditions were smaller than the control group, the difference in Siin had statistic sigof prefrontal and anterior cingulate cortex of ADHD were weaker than the control group. Conclusions The results suggest that, due to the inadequate allocation of attention resources of the children with ADHD, they have conflict monitoring function defects compare with normal children. The function defects of conflict information processing related brain areas may be the main neural mechanism. The result of the behavior and ERP can become the reference indicator for the early diagnosis and treatment of ADHD.

Objective To investigate pathological mechanism of dysfunction of executive control in children with attention-deficit hyperactivity disorder (ADHD) ,using a new resting-state functional magnetic resonance imaging(fMRI) index, fractional amplitude of low frequency fluctuation (fALFF). Methods Thirty children of school age with ADHD and thirty gender, age and education-matched healthy controls were experienced restingstate fMRI scans. fALFF approach was used to analyze blood oxygen level-dependent fMRI(BOLD-fMRI) data in resting state. Results Compared with the normal controls,the ADHD showed decreased fALFF in the bilateral superior frontal gyrus( BA10, t=5. 40,4.11 ,Z =4.81,3.82),bilateral middle frontal gyrus( BA9,BA46, t=5.72,5.37, Z = 5.04,3.08 ), right medial frontal gyrus ( BA 10, t = 5.53, Z = 4.90 ) and left precuneus ( t = 3.81, Z =3.57). And the ADHD showed increased fALFF in the bilateral limbic lobe (BA36, t = 4.37,5.20, Z = 4.02,4.66 ), right brainstem ( t = 4.77, Z = 4.34) and bilateral cerebellum ( t = 4.65,4.83, Z = 4.24,4.38 ). Conclusion The results suggest that lower activition of frontal may be the core deficit of executive control with ADHD in resting state,and high activation in several brain regions may be related to compensatory effect.
