To evaluate the morphology of atrial septum by the live three-dimensional echocardiography (L3DE) and its value of clinical application, L3DE was performed in 62 subjects to observe the morphological characteristics and dynamic change of the overall anatomic structure of atrial septum. The study examined 49 patients with atrial septal defect (ASD), including 3 patients with atrial septal aneurysm, and 10 healthy subjects. ASD in the 35 patients was surgically confirmed. The maximal diameters of ASD were measured and the percentages of area change were calculated. The parameters derived from L3DE were compared with intraoperative measurements. The results showed that L3DE could directly and clearly display the morphological features of overall anatomic structure of normal atrial septum, repaired and artificially-occluded atrial septum, atrial septal aneurysm. The defect area in ASD patients changed significantly during cardiac cycle, which reached a maximum at end-systole and a minimum at end-diastole, with a mean change percentage of 46.6%, ranging from 14.8% to 73.4%. The sizes obtained from L3DE bore an excellent correlation with intraoperative findings (r=0.90). It is concluded that L3DE can clearly display the overall morphological features and dynamic change of atrial septum and measure the size of ASD area accurately, which is important in the decision to choose therapeutic protocols.

Objective To determine the occurrence rate of liver toxicity and related risk factors after receiving highly active an-tiretroviral-therapy(HAART)by the non-nucleoside reverse transcriptase inhibittor.Methods To observe the changes of liver func-tion indexes before and after antiviral therapy in 102 patients receiving HAART,the incidence rates of the liver toxicity were com-pared between nevirapine(NVP)and efavirenz(EFV)and the risk factors of liver toxicity after treatment were analyzed.Results A-mong 102 patients,73 cases accepted the treatment of NVP,the incidence rate of hepatotoxicity was 35.6%,29 cases accepted the treatment of EFV,the incidence rate of hepatotoxicity was 13.8%,the hepatotoxicity incidence rate had statistically significant difference between the two treatment methods(χ2 =4.761,P =0.029).Co-infected by hepatitis C virus(HCV)and baseline ALT el-evation were the independent risk factors of hepatotoxicity occurrence(P <0.05).Conclusion The patients receiving the treatment of NVP are more likely to have hepatotoxicity than the patients receiving the treatment of EFV.Co-infected by HCV and baseline ALT elevation are the independent risk factors of hepatotoxicity occurrence.

Objective To assess right ventricular(RV) regional and global function in patients with repaired tetralogy of Fallot (TOF) by speckle tracking imaging (STI).Methods 36 asymptomatic patients with repaired TOF whose postoperative period is more than one year and 35 healthy controls were studied.RV longitudinal peak systolic strain (ε),strain rate (SRs) were measured in RV free wall and interventricular septum(IVS) for basal,mid and apical segments by STI from the apical 4-chamber view,RV global longitudinal peak systolic strain (GLS),strain rate (GLSRs),early diastolic strain rate (GLSRe) and late diastolic strain rate (GLSRa) were measured from the above view.The correlations between RV systolic functional parameters and the postoperative period,degree of pulmonary regurgitation (PR) and QRS duration were explored.Results ①Compared with controls,εand SRs of RV free wall and IVS for most segments,GLS,GLSRs,GLSRe,and GLSRa were significantly impaired in patients with repaired TOF (P ＜ 0.05 for all).Both GLS and GLSRs were lower in postoperative patients with transannular patch than in those with RV out tract patch.②In comparison with controls,GLS,GLSRs,GLSRe and GLSRa were decreased in postoperative patients with mild,mid and severe PR,Whereas,there was no difference in RV global function among the patients with varying degree of PR.③GLSRs of RV was correlated inversely with postoperative period and QRS duration(r1--0.431,P1 =0.009 ; r2 ==-0.469,P2-0.004),RV GLS and GLSRs had no correlation with PR.Conclusions RV regional and global function in patients with late repaired TOF are decreased,STI can early detect right ventricular dysfunction in asymptomatic patients with repaired TOF.The type of operation impacts on late prognosis,RV abnormal deformations are associated with electrical depolarization abnormalities.

Objective To evaluate the practical value of the method of contrast enhanced ultrasoundguided reduced-fine needle aspiration (CEUS-FNA) in decreasing the complications of prostate nodule puncture.Methods Nine hundred patients with suspected prostate cancer(PCa) who underwent traditional 10-point blind transperineal prostate nodule puncture(n =548) or CEUS-FNA(n =352) were collected retrospectively and classfied into normal group or CEUS group,respectively.The ratio of prostate cancer diagnosis,number of punctur and compliations were observed in both groups.Results Altogether 362 PCa were diagnosed from 900 patients.Among these cases the diagnosis ratio of normal group was 38.0％ (208/548) and that of CEUS group was 43.8 ％ (154/352).There was no significant difference in diagnosis ratio between two groups (x2 =2.992,P =0.084).The puncture number of normal group were more than that of CEUS group(P ＜0.01).There were 134 cases occurred infection and other complications in tradition group and 56 cases in CEUS group.The complication rate in normal group was higher than that in CEUS group (24.5 ％ vs 15.9 ％),with significant differences between the two groups (x2 =9.393,P =0.002).Conclusions CEUS-FNA could reduce puncture number,but not decrease the PCa diagnsis rate.And also that could reduce the complication rate of prostate puncture.

Objective To investigate the value of two-dimensional speckle tracking imaging (2D-STI) in assessing left ventricular global and regional myocardial function in normal rats. Methods Echocardiography was performed during low-dose dobutamine stress in 20 normal adult male Wistar rats. High frame rate of 2D images were recorded from the left ventricular short-axis views at the papillary muscle level. Peak systolic radial strain (PRS) and circumferential strain (PCS) of each segment, left ventricular global peak systolic radial strain (G_(PRS)) and circumferential strain (G_(PCS)) were measured at EchoPAC work station. Left ventricular internal diameter at diastole (LVIDd), systole (LVIDs), fractional shortening (FS) and ejection fraction (EF) were measured with anatomical M-model echocardiography. Dynamic changes of each index during stress experiment were observed. The correlations between EF and left ventricular global two-dimensional strain (G_(PRS), G_(PCS)) were analyzed respectively. Results PRS was similar in all segments of mid-ventricular in short-axis view (P>0.05) at baseline, while PCS of each segment showed heterogeneity, with the anteroseptal and anterior wall showing the largest value and the inferior wall showing the lowest value (P<0.05). G_(PRS), G_(PCS), PRS and PCS of each segment increased correspondingly when the dobutamine dose increasing, as well as FS and EF, whereas LVIDd and LVIDs decreased. When dobutamine dose was 10.0 μg/(kg·min), these parameters were not significantly different compared with those of 5.0 μg/(kg·min) (P>0.05). Conclusion With good reproducibility, 2D-STI can noninvasively and easily assess global and regional left ventricular myocardial deformation of normal rats at rest and during low-dose dobutamine stress.

Objective To investigate the sleep structure of children with attention deficit hyperactivity disorder (ADHD) and the differences among subtypes of ADHD.Methods Ninety children with ADHD were diagnosed in Department of Neurology, the Children's Hospital Affiliated to Capital Institute of Pediatrics between June 2012 and June 2013, including 75 boys and 15 girls,6-14 years old [(9.5 ± 2.4) years old], and among them there were 55 cases of ADHD-combined type, 25 cases of ADHD-inattentive type, and 10 cases of ADHD-hyperactive impulsive type.Thirty healthy children whose age and sex matched with ADHD group,came from Beijing and the surrounding area,were selected as the healthy control group,including 23 boys and 7 girls,6-14 years old [(9.2 ± 2.9) years old].Two groups underwent full overnight sleep assessment.Results The latency of rapid eye movement(REM) in children with ADHD was (146.58 ± 47.28) minutes, and the sleep latency was 19.00 minutes [(8.25-37.50) minutes];while the latency of REM in healthy control group was (87.55-± 13.59) minutes, and the sleep latency was 9.00 minutes [(3.50-13.63)minutes].Compared with healthy control group, children with ADHD demonstrated the increased latency REM and sleep latency, and decreased sleep efficiency,the increasing times of awakening and total duration,and these differences were all statistically significant(all P ＜ 0.05).The percentage of non-rapid eye movement(NREM) phase Ⅱ in ADHD hybrid was lower than the ADHD attention-deficit(t =2.012,P ＜ 0.05).Sleep latency in ADHD attention-deficit was longer than the ADHD hybrid(t =2.964,P ＜ 0.05).No statistical differences were found among the various types in other indicators.The prevalence of periodic limb movements in sleep(PLMS) was 27.78％ (25/90 cases) in ADHD group and the prevalence of PLMS was 3.30％ (1/30 cases) in the healthy control group.The differences in prevalence between 2 groups were statistically significant (x2 =8.053, P ＜ 0.05).Conclusions Children with ADHD significantly display more problems with sleep.Sleep latency and NREM Ⅱ are different between ADHD attention-deficit and ADHD hybrid.
