Objective To analyze CT and MRI manifestations of the aneurysmal bone cyst and to evaluate the value of its imaging diagnosis.Methods The manifestations of CT and MRI of the aneurysmal bone cyst confirmed by operation or puncture were analysed retrospectively.Results On CT images,there were obvious liqued-liqued level within the lesions in 16 cases,in which,the CT values in up part was lower than that in low part,and there were obvious soft tissue mass in secondary aneurysmal bone cyst.While,on MRI,all lesions appeared obvious liqued-liqued level except one secondary example,and the soft tissue mass of secondary aneurysmal bone cyst was clear showed.Conclusion Most of aneurysmal bone cyst appear liqued-liqued level within the lesions on CT and MRI,it is a characteristic sign,but not the only one.

Objective To study the relationship between thyroid hormone level and 24h urine protein quanti-tation in patients with severe preeclampsia. Methods From August 2015 to October 2017,180 patients with severe preeclampsia who were treated in the Third People's Hospital of Qingdao were selected. The level of thyroid-stimula-ting hormone ( TSH) was detected by chemiluminescence particles immune method. According to the test results,the patients were divided into normal group (n=110,TSH=0. 3-3. 3mU/L) and hypothyroidism group (n=70,TSH>3. 3mU/L). Another 240 healthy pregnant women who admitted in the Third People's Hospital of Qingdao during the same period were selected as control group. The TSH,free triiodothyronine (FT3),free thyroxine (FT4) levels and 24h urine protein quantitation were compared among the three groups. The correlation between the level of thyroid hormone and 24h urine protein quantitation,the results of thyroid autoantibody in patients with severe preeclampsia were analyzed.Results The FT4,FT3 levels in the normal group were (11.92±2.54)pmol/L,(5.22 ±1.25)pmol/L, respectively,which in the hypothyroidism group were (9. 02 ± 1. 09) pmol/L,(3. 92 ± 1. 57) pmol/L,respectively, which were all lower than those in the control group (t=6. 657,16. 758,13. 221,18. 245,all P<0. 05),which in the hypothyroidism group were lower than those in the normal group (t=9. 031,6. 149,all P<0. 05). The TSH,24h urine protein quantitation levels in the normal group were (2. 56 ± 0. 86) mU/L,(66. 51 ± 18. 52) mg,respectively, which in the hypothyroidism group were (5. 87 ± 3. 02) mU/L,(79. 14 ± 12. 58) mg,respectively,which were all higher than those in the control group(t=2. 330,7. 197,16. 417,13. 335,all P<0. 05),which in the hypothyroidism group were higher than those in the normal group (t=10. 883,5. 014,all P<0. 05). There was positive correlation between serum TSH and 24h urine protein quantitation in patients with severe preeclampsia (r=0. 254,P=0. 001). There was negative correlation between FT4 and 24h urine protein quantitation (r= -0. 182,P=0. 025). There was no correlation between serum FT3 and 24h urine protein quantitation (r= -0. 080,P=0. 330). The positive rates of TPO Ab,TG Ab were 12. 86％,18. 57％ in hypothyroidism group,there were no statistically significant differences compared with 10. 91％,14. 55％ in the normal group (χ2 =0. 158,0. 513;P=0. 691,0. 474). Conclusion There is correlation between thyroid hormone levels and 24h urine protein quantitation in patients with severe preeclampsia. It has great significance for clinical treatment of severe preeclampsia by detecting the level of thyroid hormone.

To develop a blue cap anticoagulant tube blood volume measuring card of to solve the problem of insufficient or excessive blood collection in clinical coagulation specimens.The device was composed of a measuring card,a transparent housing with a base and a tube holder.The measuring card was divided into qualified and unqualified areas,the housing was used to insert the card,the tube holder was used to place blood collection tubes.The device was used by clinical nurses to judge the adequacy of blood collection volume in blue cap anticoagulant tube.After the use of the device,the failure rate of clinical blue cap anticoagulation tube specimens submission was reduced from 6.71‰ to 2.73‰,shortened the time limit for specimen submission.At the same time,the device made the rejection judgment of department specimens more standardized and avoided the acceptance of unqualified specimens caused by subjective judgment errors.The device has simple structure,convenient operation and strong practicability,and has promotion value.

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.
