Purpose To investigate the value of real-time three-dimensional contrast-enhanced ultrasound (RT3D-CEUS) for the evaluation of blunt renal trauma hemorrhage. Materials and Methods Nine healthy New Zealand white rabbits were randomly divided into three groups, and after heparinization, the models of ongoing hemorrhage of blunt renal trauma were developed by self-made minitype striker in the three groups with different force levels:77.2 N (group A), 106.2 N (group B), 135.1 N (group C). All rabbits were performed ultrasonography (US), color Doppler flow imaging (CDFI) and RT3D-CEUS before and after strike (within 20 minutes). The results achieved by US, CDFI, 2D-CEUS (A-plane results in RT3D-CEUS) and RT3D-CEUS were compared with each other, and further compared with the pathological results of the executed animals after blood pressure decreased lower than 40 mmHg. Results All rabbits showed traumatic renal lesions and it proved that the bigger the force the heavier the injury (group A: 1 case of levelⅠ, 2 cases of levelⅡ;group B:3 cases of levelⅢ;group C:1 case of levelⅢ, 2 cases of level Ⅳ ). After strike, US identified the presence of increasing hematoma under the capsule but could not detect active bleeding. In CDFI, only 1 case was detected ongoing hemorrhage. 2D-CEUS clearly presented the bleeding in all cases. RT3D-CEUS presented a vivid real-time and stereoscopical image of active hemorrhage in all cases and also showed that the wider the bleeding area was shorter than the shock duration time. Conclusion RT3D-CEUS can present a real-time dynamic bleeding and locate headstream of blood in renal trauma vividly and stereoscopically, and can be used to preliminarily evaluate the degree of ongoing hemorrhage in traumatic kidney.

Purpose To prepare the tranexamic acid liposome with high encapsulation efficiency and stability, through interaction of avidin and biotin, and to prepare its microbubble-liposome compound whose properties are to be assessed. Materials and Methods Thin film hydration technology was used to prepare tranexamic acid liposome. Taking encapsulation efficiency as indication, the microbubble-liposome compound was optimized by the design of orthogonal experiment. The basic properties of the compound were tested and the acoustic characteristic was measured by ultrasound and gray-scale values. Results The optimum formula of tranexamic acid liposome were as follows:molar ratio of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine, cholesterol and 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[biotinyl (polyethylene glycol) 2000] was 85∶10∶5;concentration of tranexamic acid was 5.0%;ultrasonic time was 15 min. The encapsulation efficiency was 62.62%. The size was approximately (104.00±1.84) nm. The Zeta potential was approximately (-50.50±0.56) mV. The liposome was good in stability. The size of the microbubble-liposome compound was approximately (4.56±0.28)μm. Under the microscope, they were round with transparent center, evenly distributed without aggregation. The acoustic characteristic of the compound in vitro showed typical characteristics of microbubble, which was compatible with the results under the microscope. As the concentrations of the compound increased, both ultrasound imaging effect and the gray-scale values enhanced. However, to avoid acoustic shadows, the imaging concentrations were supposed to be at least lower than 1.15×108/ml in vitro. Conclusion The preparation of the tranexamic acid microbubble-liposome compound can be optimized by taking encapsulation efficiency as reference, and it can be effectively traced by ultrasound according to its acoustic characteristics in vitro.
