Chinese Journal of Interventional Imaging and Therapy 2019;16(8):475-480
Objective: To observe the value of real-time three-dimensional echocardiography (RT-3DE) for evaluating left ventricular global and regional systolic function in children with left ventricular noncompaction (LVNC). Methods: According to left ventricular ejection fraction (LVEF) detected with conventional echocardiography, 34 children with LVNC were divided into LVEF normal group (group A, LVEF≥50%, n=25) and LVEF reduced group (group B, LVEF<50%, n=9), while 20 healthy children were selected as normal control group (group C) at the same period. RT-3DE examinations were performed, left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV) and LVEF were measured. The ratio of noncompaction myocardium to compaction myocardium (NC/C) at the thickest area on end-systolic count were calculated. The involvements of left ventricular 17-segment myocardium were observed. Regional end-diastolic volume (rEDV), regional end-systolic volume (rESV) and regional ejection fraction (rEF) were obtained with left ventricular volume-time curve analysis. The data were statistically analyzed. Results: There was no statistical difference of LVEDV (t=-0.17, P=0.87), LVESV (t=0.79, P=0.44) and LVEF (t=-1.72, P=0.10) between group A and C, nor of LVEDV (t=1.62, P=0.15) between group B and C. In group B, LVESV significantly increased (t=2.85, P=0.03), while LVEF significantly decreased compared with that in group C (t=-6.15, P<0.01). No statistical difference of NC/C was found between group A and B (t=-1.15, P=0.27), but the number of affected segments in group A was significantly fewer than that in group B (t=-4.59, P=0.03). There was no statistical difference of rEDV and rESV in all of 17 segments of myocardium in left ventricular between group A and C (all P>0.05), while rEF of apical septal, inferior and lateral segments, as well as med inferoseptal, inferior and inferolateral segments were significantly different between group A and C (all P<0.05). There was no significant difference of rEDV in all 17 segments of myocardium in left ventricular between group B and C (all P>0.05), while rESV of basal inferolateral and anterolateral segments, med anterior, anteroseptal, inferior, inferolateral and anterolateral segments, apical anterior, septal and lateral segments, as well as rEF in all 17 segments of myocardium in left ventricular were significantly different between group B and C (all P<0.05). Conclusion: RT-3DE can be used to evaluate the regional and global systolic function, which is helpful to early diagnosis, treatment and prognosis of LVNC children.

9.Focus on the special population with hepatitis B virus infection: Early diagnosis, early treatment, and early benefits
Journal of Clinical Hepatology 2022;38(11):2441-2443
Hepatitis B virus (HBV) infection is a major public health problem worldwide. With the extensive prophylactic vaccination with hepatitis B vaccine for neonates and an increasing number of patients receiving antiviral treatment, remarkable achievements have been made in HBV infection among Chinese children. However at present, there is still a high HBsAg-positive rate among the adults in China, and with more and more special populations, it is necessary to perform timely screening and diagnosis and give antiviral therapy as early as possible, so as to prevent or delay the progression to liver cirrhosis, liver failure, and hepatocellular carcinoma after HBV infection. The selection of treatment timing and drugs should not only focus on HBV virology and liver function, but also consider chronic underlying diseases, mother-to-child transmission, and reactivation of HBV in patients receiving chemotherapy and immunosuppressants, thereby realizing the timely screening, diagnosis, and treatment of the population at a high risk of HBV and special populations and bringing more benefits to patients.

OBJECTIVE:
To establish a new mechanical model of distal humerus in children with epiphysial cartilage, stimulate supracondylar humerus fracture and perform three dimensional finite elements, and study effect of pins numbers, pin tract, outlet height and pin configurations on stability of fixation.
METHODS:
Three dimensional computed tomography (CT) data of 6-year-old boy with distal humerus was downloaded from picture archiving and communications systems software (PACS), the data of picture was imported into Simpleware and SolidWorks 2016 software to establish distal humerus fracture in children contained ossific nucleus of the capitellum (ONC) and distal cartilage. Normal extense supracondylar humerus fracture model was established to stimulate configurations of crossed and lateral pinning fixation, 30 N was added on the direction of flexion extension and varus valgus, while 50 N was added on the direction of internal and external turning. Stability was analyzed by displacement degree of distal fracture.
RESULTS:
Among 2-pin configurations, 2-crossed pins were more stable against rotation forces which could resist rotation stress over 2 585 Nmm/ °, while low position through ONC of 2-divergent lateral pins were more stable, which could resist stress of 45 N /mm and 190 N /mm during the test of resistant strains and varus-valgus stress. The third pins was added into the more stable lateral 2-pins, the stability in all directions were increased obviously, and 3 crossed pins is the most stable, stress of flexion-extension, varus-valgus and internal-external turning were 198 N /mm, 395 N /mm and 6 251 Nmm/ °.
CONCLUSION
Two-divergent lateral pins could provide enough stability for supracondylar humerus fracture in children. In two-crossed pins, the upper border of MDJ could provide the best stability. Three-crossed pins could offer the best stability against both translation and rotation forces.
