Objective To study the Mediating effect of insecurity between childhood abuse and emotional distress of medical students,and to provide basis to intervene their mental disorder.Methods Through stratified sampling,262 medical students in Jiangsu were investigated by the Personal Report of Childhood Abuse( PRCA),Self-Rating Feeling of Insecurity Scale( SRFIS),Beck Depression Inventory( BDI ),Self-rating Anxiety Scale(SAS)and Suicide Ideation Scale(SIS).A path analysis was applied by Analysis of Moment Structures(AMOS) version 7.0.Results The path analysis showed that childhood abuse was directly related to insecurity of medical students ( β =0.538,P ＜0.01 ),and was directly related to emotional distress ( β =0.435,P ＜ 0.01 ).Insecurity were directly related to emotional distress of medical students ( β =0.342,P ＜ 0.05 ).Insecurity mediated partly the relationship between childhood abuse and emotional distress of medical students.The model fit indexes were X2/df =1.365 ＜ 3.000,P =O.082 ＞ 0.05,RMSEA =0.037 ＜ 0.050,GFI =0.971,AGFI =0.940,NFI =0.943,RFI =0.902,IFI =0.984,TLI =0.972,CFI =0.984.Conclusion Insecurity as mediated variable mediates the relationship between childhood abuse and emotional distress of medical students.

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.
