Objective To measure the morphological parameters of cervical endplate of Chinese by using computed tomography (CT)scans,and to provide an accurate morphometric basis for designing and developing the cervical disc prostheses.Methods 80 healthy subjects were scanned by CT.The parameters of each cervical vertebra from C3 to C7 were measured by CT scans including upper anteroposterior length (APLu),upper center mediolateral length (CMLu),lower anteroposterior length (APLl) and lower center mediolateral length (CMLl).These parameters were compared between genders and among different vertebral levels.Results The values of APLu, CMLu,APLl and CMLl were increased with the decreasing of cervical segment (P APLu = 0.023,P CMLu = 0.007, P APLl =0.035,P CMLl < 0.001).There was statistically significant difference in morphological parameters between genders (P < 0.05).Compared with the reported data of other different populations,the statistically significant difference in morphological parameters also existed in the study.Conclusion The study provides an accurate morphological basis for designing the suitable artificial cervical disc for Chinese population.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
