Abstract: A freeze-dried plasma (FDP) for well-balanced coagulation and fibrinolysis, a method of preparation and use thereof are provided, relating to the technical field of hemostatic preparations. The FDP for well-balanced coagulation and fibrinolysis is compounded with appropriate concentrations of coagulation factors, anticoagulant factors, fibrinolytic factors, fibrinolysis inhibiting factors, and von Willebrand factor according to different changes in a coagulation-fibrinolysis system after different types of tissue and organ injuries. The FDP for well-balanced coagulation and fibrinolysis is used for hemostatic resuscitation of general severe trauma, severe hepatic trauma, severe craniocerebral injury, and severe trauma with seawater immersion and other types of injuries, exhibiting a desirable hemostatic resuscitation effect. It does not cause thrombosis in uninjured parts, and may reduce the amplitude of lactate increase after the trauma.

Abstract: Disclosed are a remote medical guidance method and system based on virtual reality, belonging to the technical field of medical guidance. The method includes: obtaining an action sequence of remote guidance personnel for medical operations; and generating a three-dimensional operation model based on the action sequence and displaying the three-dimensional operation model in an operation live scene. The present disclosure achieves remote guidance of medical operations based on virtual reality, eliminating the need to relocate patients or medical personnel and avoiding missing the optimal treatment time window.

Abstract: Provided is an intelligent system for search and rescue in a special environment such as a disaster, including a body surface feature extracting apparatus, a vital sign extracting apparatus, a speech feature extracting apparatus and a network transmission apparatus that are successively in communication connection with one another. The body surface feature extracting apparatus uses a gated recurrent unit (GRU) network model for transmission and storage. The speech feature extracting apparatus includes a sound collecting module, a sound feature extracting module and a sound analyzing and processing module that are successively in communication connection with one another, with the sound analyzing and processing module being provided with a noise database comprising a plurality of ambient sounds.

Abstract: A method for preparing lyophilized platelets and use in preparation of a traumatic hemostatic product are provided. The preparation method adopts appropriate lyophilization conditions, has a faster lyophilization process than conventional lyophilization processes, and can increase an activation rate of LPs to about 70% while maintaining an activity of the LPs. The lyophilized platelets prepared by the preparation method shows stronger migration ability than conventional LPs, have higher maximum amplitude (MA) of blood clots in in vitro and in vivo experiments than the conventional LPs, and exhibit an excellent hemostatic effect. In addition, the platelet transfusion stock solution has enhanced coagulation activity after transfusion into trauma simulation animals compared with the conventional LPs, and is distributed to injury sites in a larger quantity, thereby better promoting coagulation and improving post-traumatic coagulation dysfunction.
