Objective To explore the protective effect of vitamin E on the rabbit bladder after partial outlet obstruction artificially setup. Methods A total of 28 New Zealand white male rabbits were divided into 4 groups (group A in 6,group B in 6,group C in 8 and group D in 8).Group A,B and C were fed a regular diet,and group D were placed on a diet enriched with 600 mg vitamin E.After 4 weeks partial outlet obstruction was created in groups C and D,while group B underwent sham operation. After 4 weeks of obstruction each rabbit was sedated and cystometry was repeated.After cystometry the bladder was weighed.The gene expression of sarcoplasmic endoplasmic reticulum,calcium,magnesium,adenosine triphosphatase (SERCA2) in bladder was detected by using RT-PCR assay,while the protein level of SERCA2 was measured by Western blot analysis. Results All parameters measured were approximately identical in nomal rabbits(Group A) and shum operation rabbits(group B).Thus,these 2 groups were combined as the control group(Group A and B).Partial outlet obstruction resulted in bladder weight increased significantly in obstructed groups given vehicle group C(13.07?1.71)g and those vitamin E group D(11.80?2.01)g,4-fold higher than in the control group (2.81?0.30)g(P

Objective: To compare efficacies and complications of total hip arthroplasty ( THA ) with subtrochanteric osteotomy for treating patients with Hartofilakidis types C1 and C2 developmental dyspla-sia of the hip ( DDH) .Methods:Retrospective analysis was performed in 32 patients with DDH who un-derwent THA.These patients were divided into two groups according to Hartofilakidis classification, 17 patients in type C1 and 15 in type C2.Their HSS and WOMAC scores, leg length discrepancy (LLD), hip joint image data and complications were evaluated.Results:HSS scores in type C1 was changed from preoperative 43.7 ±4.6 to postoperative 87.2 ±7.1 (P<0.001), together with WOMAC scores 43.6 ± 4.3 to 87.5 ±6.7 (P<0.001).HSS scores in type C2 was changed from preoperative 44.4 ±5.4 to postoperative 86.5 ±8.0 (P<0.001), together with WOMAC scores 44.1 ±4.1 to 86.7 ±8.1 (P<0.001).Four cases in type C2 and one case in type C1 presented intraoperative fracture which all healed during the postoperative follow-up.The postoperative X-ray films showed that the joint prosthesis location was satisfactory, the surrounding bone was not dissolved and the bone at femur osteotomy site healed with no infection.Conclusion:For unilateral high dislocation DDH patients, THA with femur osteotomy can be effective and safe.No significant differences were found between types C1 and C2, however intraoper-ative fracture in type C2 should be paid attention to.

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.
