Jian, WANG ; Chun-song, KANG ; Yan-ping, ZHENG ; Ji-ping, XUE ; Rui, ZHANG

Chinese Journal of Medical Ultrasound (Electronic Edition).2008;5(2):229-234.

Objective To investigate the onset of left ventricular remodeling (LVRM) after acute myocardium infarction (AMI) and its changes within 6 hours in dogs on echocardiography. Methods AMI was induced in 14 dogs by ligating the left anterior descending arteries. Eight myocardium infarcted models were successful and were sacrified for pathological study. The indices of LVRM: wall infarction thickness (WIT), the wall motion score index (WMSI), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV) and left ventricular ejection fraction (LVEF) were evaluated before and 1 h, 2 h, 3 h, 4 h, 5 h and 6 h after operation. Results Compared with the pre-operation, WIT and LVEF were decreased (P<0.01), LVESV and WMSI were increased (P<0.01), and LVEDV was increased (P<0.05 or P<0.01) at every time point after operation. WIT had no significant difference at 1 h, 2 h, 3 h, 4 h, 5h and 6h after operation (P＞0.05). LVEDV, LVESV were higher (P<0.05) and LVEF was lower (P<0.05 or P<0.01) at 4 h, 5 h, and 6 h than at 1 h, and 2 h after operation. WMSI was higher at 3 h, 4 h, 5 h, and 6 h than at 1h (P<0.05). Conclusions In our experiment, LVRM occurred at 1 h after AMI in dogs. Thus echocardiography may evaluate early LVRM.

Liang, YU ; En-sheng, XUE ; Li-wu, LIN ; Shun, CHEN ; Yi-mi, HE ; Shang-da, GAO ; Xiao-dong, LIN

Chinese Journal of Medical Ultrasound (Electronic Edition).2008;5(2):303-308.

Objective To study the clinical value of color Doppler ultrasonography in typing tuberculous epididymitis.Methods The appearances of color Doppler ultrasound and the findings on operation were analysed in 33 patients with tuberculous epididymitis.Results Of the 33 patients,epididymis appeared as diffusely and heterogeneously enlarged lesions with increased flow in 2 cases,appeared as nodular lesions in 13 cases including nodi with echofree space in 3 cases, nodi with high-level echo patches in 3 cases, and low echo-level nodi in 7 cases. Multiple lesions in scrotum were detected in 17 cases, of whom epididymis up to 11 cases appeared as diffusely enlarged heterogeneous lesions with flow increased.The sonographic appearancs of tuberculous epididymitis could be divided into 3 types:diffusion type, nodus type and complicated type. Nodus type included 3 subtypes: purulence type, calcification type, and cheese type.The accuracy rate of ultrsound diagnosis was 87.9%.Conclusions Testis is easy to be involved when epididymitis appears as diffusion type, so surgical treatments should be early.Purulence type and complicated type need surgical treatments while calcification type does not. Antituberculous drug treatments can be tried before surgical treatments in cheese type.Sonography of urinary system is helpful for the diagnosis of asymptomatic tuberculosis in urinary system when tuberculous epididymitis is first suspected on sonography.

Shu-jiao, JI ; Jian-jun, YUAN ; Chang-hua, WEI

Chinese Journal of Medical Ultrasound (Electronic Edition).2008;5(2):267-272.

Objective To quantitatively evaluate the left ventricular systolic synchrony in patients with chronic renal failure (CRF) by real-time three-dimensional echocardiography (RT-3DE). Methods Thirty patients with CRF and twenty-five normal subjects were enrolled in this study.The M-mode ejection fraction (M-EF), left ventricular end diastolic internal diameter (LVIDd), interventricular septum diameter (IVSd), left ventricular posterior wall diameter (LVPWd) were obtained on two-dimension. The global and regional volume-time curves were obtained on three -dimensional. The end diastolic volume (LVEDV),end systolic volume (LVESV) and ejection fraction (LVEF) of left ventricule, the time to minimal systolic volume (Tmsv) of 16,12,6-segmental standard deviation (Tmsv16, 12, 6-SD), maximal difference (Tmsv16, 12, 6-Dif) were derived from Qlab software . The above parameters as a percentage of the cardiac cycle with different heart rates between patients were also calculated from the Qlab software, which were Tmsv16, 12, 6-SD% and Tmsv16, 12, 6-Dif %, rspectively. Results The indices of HR, LVIDd, IVSd, LVPWd and LVESV were significantly higher while LVEF was significantly lower in the CRF group than those of the control group (P<0.05 or P<0.01); The indices of systolic asynchrony of Tmsv16,12-SD%, Tmsv16,12-Dif, Tmsv16 ,12 ,6-SD/R-R%,Tmsv16,12,6-Dif/R-R% were significantly larger in the CRF group than those of the control group(P<0.05 or P<0.01). Conclusions RT-3DE provides a simple, intuitional and noninvasive approach to assess the systolic synchrony of all the LV segments simultaneously and LVEF in patients with chronic renal failure.
