Platelets are important component in the blood which play vital role in physiological hemostasis. In clinic, platelets are usually transfused to patients suffered from idiopathic thrombocytopenic purpura,thrombocytopenia after chemotherapy and radiotherapy,or hemorrhagic thrombocytopenia caused by other reasons. Storage time for platelet concentrates is limited to five days at room temperature, leading to an increasing number of scrap rate, therefore the prolonging the storage time is important for clinical application. Storage at -80°C is an ideal long-term cryopreservation method for platelet concentrates. In this article, platelets cryopreservation,the mechanism of frozen injury and the protective mechanisms of platelets were reviewed.

Purpose: This study aims to describe a fixation technique for coronoid fractures using suture buttons, and to biomechanically evaluate this technique in comparison to screw fixation as a time-zero pilot study.
Methods: An O'Driscoll type 2 anteromedial coronoid facet (AMCF) fracture was simulated in 20 fresh-frozen human elbows. The specimens were randomized into two groups and fracture fixation was performed with either a suture button system or a 3.

After severe trauma, but also perioperatively, massive bleeding is associated with increased morbidity and mortality. In severely injured patients, hemorrhagic shock remains to be the main cause of death in addition to traumatic brain hemorrhage. In non-cardiac surgery, a surgical bleeding complication increases perioperative morbidity (intensive care length of stay, acute renal failure, infections, thromboembolic complications) by a factor of three to four and mortality by a factor of six.
