Objective To preliminary investigate fetal left heart function of fetuses in α-thalassemia using spatio-temporal image correlation (STIC).Methods 95 volumes from fetal hearts in singleton pregnancies at 20-28 weeks of gestation were collected.STIC datasets were frozen in end-systole and enddiastole.Ventricular volumes were measured using VOCAL,Inversion and SonoAVC.The stroke volume was calculated from these measurements.Results All data sets could be measured with all three techniques in this study.The intraclass correlation coefficients (ICCs) between techniques were all ＞ 0.90.The time necessary to measure the stroke volume was significantly shorter using SonoAVC than using VOCAL and Inversion.Bland-Altman plots showed no clinically significant mean percent differences between stroke volume measurements obtained from each ventricle using three techniques.The left ventricular end-systole volume(ESV),stroke volume(SV)and ejection fraction(EF)was significantly different than fetuses with normal heart (P ＜ 0.05).Conclusions This study shows the feasibility of measuring left ventricular volumes during either systole or diastole and thereby calculating stroke volumes with all three techniques.And there was a high degree of reliability for all three techniques,as shown by excellent ICCs.There was good accuracy of STIC techniques in measuring fetal left ventricular volumes with cardiomegaly.

Objective Few studies are reported on the construction of a finite element model of human complex knee joint using multimodality CT and MRI images.In this study, we developed a finite element model of the knee joint for total knee arthroplasty (TKA) using matched and fused CT and MRI data, hoping to provide a useful tool for the simulation study of knee joint biomechanics of TKA.Methods The CT and MRI image data about an intact knee of a 26-year-old male volunteer were imported into the Mimics software for the establishment of 3D models of bony and soft-tissue structures.A complete knee model was developed following the registration and fusion of the constructed 3D models based on the external landmarks.After the simulated implantation of TKA components, a finite element model of the TKA knee was constructed with the Hypermesh software.Then the finite element model was analyzed following the definition of its material behavior, boundary conditions and loading.Results The finite element model of the TKA knee, which was composed of bones, ligaments, components, polyethylene insert and bone cement, was developed from CT-MRI image registration and fusion and maintained its important spatial relationship among different structures in the TKA knee.The results obtained from the finite element analysis showed the characteristics of stress distribution in the TKA knee.Conclusion The finite element model of the knee joint for TKA can be established by matching and fusing CT and MRI image data, which can be employed as a useful tool for the study of knee joint biomechanics of TKA.

In nature, honeybees are the most important pollinators. They play a vital role in both protecting the diversity of natural ecosystems, and maintaining the yield-improving effects of agroecosystems. But in recent years, epidemic disease in bees has caused huge losses. Black Queen Cell Virus (BQCV) is a bee pathogen that was first reported in 1955. It mainly infects bee larvae and pupae, making their bodies turn dark and black, and causing a massive decrease in the bee population. More specifically, the virus makes the exterior of the cell walls in the larvae and pupae turn black. BQCV is a seasonal epidemic, spread by means horizontal and vertical transmission, and is often unapparent. BQCV not only infects a variety of bee species, but also spiders, centipedes and other arthropods. It can also be coinfected with other honeybee viruses. In recent years, research has shown that the Nosema intestinal parasite plays an important role in BQCV transmission and bees carrying Nosema that become infected with BQCV have increased mortality. Here we summarize current research on the incidence, prevalence, geographical distribution and transmission of BQCV.
