Abstract
Critical challenges remain in trauma emergency and surgical procedures involving liver bleeding, particularly in perforating wounds that cannot be pressed and large wounds that cannot be sewn. Self-assembling peptide hydrogels are particularly attractive due to their intrinsic biocompatibility and programmability. Herein, we develop a nano-band-aid (NBA) through a three-stage self-assembly strategy of two functionalized peptides, which were first coassembled into nanofibers and then woven to a meshlike network driven by Ca2+. Then, catalyzed by blood coagulation factor XIIIa (FXIIIa), NBA underwent a third stage, self-assembly into a densely compacted physical barrier to stop and control the bleeding. As expected, NBA rapidly and efficiently stopped the bleeding in rat liver scratches while effectively reducing the inflammation around the wound and promoting the wound healing. This bionic self-assembly strategy will provide a clinically potential peptide-based treatment for fatal liver bleeding and reinvigorate efforts to develop self-assembling peptide hydrogels as hemostatic agents.

Abstract
BACKGROUND The risk of spontaneous bleeding or rupture of liver hemangiomas still remains unknown. The aim of this review was to analyze the problem of spontaneous bleeding or rupture in liver hemangiomas and to identify factors leading to bleeding in these cases. METHODS A MEDLINE search was undertaken to identify articles in English, French, German, Italian, and Spanish from 1898 to 2010. Basic data such as age and sex of patients were collected. Additional data such as risk factors or causes of rupture were also analyzed. Cases were divided into spontaneous and non-spontaneous ruptures. RESULTS A total of 97 cases are described. In 51 of the 97 patients (52.6%) a non-spontaneous rupture was identified. Only in 46 out of the 97 cases (47.4%) was a spontaneous rupture found. Non-spontaneous rupture was significantly more frequent in patients aged <40 years than in older ones (p = 0.0099). Mean size of the ruptured lesions was 11.2 cm (range 1-37 cm). Massive bleeding occurred in 88 patients (90.7%). Reported mortality over the past 20 years has been significantly lower than before (p < 0.001). The overall mortality for the period under study was ~35%. CONCLUSIONS The spontaneous rupture of a hepatic hemangioma is to be considered an exceptional event. Preventive surgery should be considered only for lesions of at least 11-cm size in special cohorts of patients.
