Abstract
Objective: To study the diagnostic value of immediate color Doppler ultrasonography on traumatic hepatic hemorrhage after tissue sampling with ultrasound-guided liver biopsy and the clinical effect of its-directed local compression hemostasis at puncture-site. Methods: 132 hospitalized patients with various liver diseases underwent ultrasound-guided hepatic puncture-biopsies, including 61 cases with diffuse parenchymal and 71 cases with focal liver lesions. Immediate postoperative color Doppler ultrasonography was performed following liver biopsy. Abnormal blood flow signal was observed at hepatic puncture biopsy site, and if there were hemorrhagic signals, ultrasound-directed local compression hemostasis was performed until the bleeding signal disappeared. F-test and Chi-square test were used for statistical analysis. Results: Immediate color Doppler ultrasonography showed traumatic hemorrhage in 36.1% (22/61) and 40.8% (29/71) cases of diffuse liver disease and focal liver disease group, respectively. All hemorrhagic signals were eventually disappeared after ultrasound-directed local compression hemostasis. The median hemostasis time was 2 min in both groups, and there was no statistically significant difference in bleeding rate and hemostasis time between the two groups (P>0.05). There were no serious complications and deaths. Conclusion: Traumatic hepatic hemorrhage along the needle puncture tract is a common accompanying condition during liver biopsy. Immediate postoperative color Doppler ultrasonography can trace bleeding signals in timely manner and direct effective compression hemostasis, so it should be used routinely to help avoid occurrence of severe hemorrhagic complications.

Abstract
Anion exchange membranes (AEMs) are a crucial constituent for alkaline fuel cells. As the core component of fuel cells, the low performance AEMs restrict the development and application of the fuel cells. Herein, the trade-off between the OH- conductivity and dimensional stability was solved by constructing AEMs with adequate OH- conductivity and satisfactory alkali resistance using Tröger's base (TB) poly (crown ether)s (PCEs) as the main chain, the embedded quaternary ammonium (QA) and Na+-functionalized crown ether units as the cationic group. Crown ether is an electron donator, and can capture Na+ to form Na+-functionalized crown ether units to conveniently transfer OH- and significantly promote the alkaline stability of the AEMs. The influence of the Na+-functionalized crown ether units on the performance of AEMs was studied in detail. The PCEs based AEMs show an obvious hydrophobic-hydrophilic microphase separation. These features make them ideal platforms for the OH- conduction applications. As expected, the as-prepared PCEs-QA-100% (100% is the degree of cross-linking) AEM with an ionic exchange capacity (IEC) of 2.07 meq g-1 has a high OH- conductivity of 159 mS cm-1 at 80 °C. Furthermore, the membrane electrode assemblies fabricated using the PCEs-QA-100% AEM possess a maximum power density of 291 mW cm-2 under the current density of 500 mA cm-2.
