Objective To study the expression of Galectin-3,CK19 and Ki-67 in the papillary thyroid carcinoma and papillary thyroid hyperplasia and to find the differential diagnostic makers. Methods A total of 200 cases, including 100 with papillary thyroid carcinoma and 100 papillary thyroid hyperplasia by Immunohistochemistry. Results The positive rates for Galectin-3,CK19 and Ki-67 in the papillary thyroid carcinoma were 100 %, 97 % and 93 %, which were significantly higher than those in the papillary thyroid hyperplasia (13 %, 31 %, 1 %) (P

Objective:To translate the Attention to Positive and Negative Inventory(APNI)and analyze the validity and reliability in Chinese undergraduates sample,to offer a convenient and reliable tool of measuring the cognitive bias for national researchers. Methods:The English-version APNI went through translation into Chinese, retroversion into English,translation into Chinese again,and revision several stages. Two parts of samples (1450 Chinese college students)were surveyed. Sample one (n=1000)was used for item analysis,exploratory factor a-nalysis (EFA),concurrent validity and reliability analysis,while sample 2 (n=450)was used for confirmatory fac-tor analysis (CFA). Totally 68 subjects of sample 1 were randomly chosen and resurveyed with an interval of one week. Beck depression inventory (BDI-II)and patient health questionnaire (PHQ-9)was used for concurrent validi-ty. Results:Item analysis indicated that the 22 items of Chinese APNI had good discriminability. EFA focused onattention to positive information(API)and attention to negative information(ANI)two factors. CFA showed good model fit (χ2 =1376,RMESA=0. 09,CFI=0. 94). Concurrent validity result showed that the total scores of BDI-II and PHQ-9 was negatively correlated with total scores of API (r=-0. 24,-0. 29,Ps<0. 01 ),and posi-tively correlated with total scores of ANI (r=0. 36,0. 31,Ps<0. 01). The Cronbach'αcoefficients of API and ANI sub-scale were 0. 86 and 0. 82,while the retest reliability coefficients were 0. 79 and 0. 62. Conclusion:It suggests that the Chinese APNI has good validity and reliability in a sample of college students,which could be used to eval-uate the cognitive bias of Chinese college students.

Objective:To explore the academic procrastination (AP) status and related factors in college students. Methods: Totally 828 undergraduates (277 male, 551 female, age 18-25 years) from Sun Yat-Sen University were investigated with a self-made questionnaire for basic information and Undergraduate Academic Procrastination Questionnaire (UAPQ) for AP status. UAPQ included overall learning procrastination (OLP), homework procrastination (HP), exam preparing procrastination (EPP) and self-learning procrastination (SLP). Students who scored more than 3 in OLP, HP, EPP, SLP were regarded as procrastinator. Result: The procrastination rates of OLP, HP, EPP, SLP were 40.7％, 29.7％, 41.5％, and 47.6％. Multiple linear regression analysis results showed that bigger (β = 0.32) and normal (β =0.15) influence for academic by mobile-phone, higher level of computer dependence (β =0.15) were positively related with academic procrastination. Higher (β =-0.27) and normal (β =-0.17) levels of grade satisfaction were negatively correlated with academic procrastination. The seniors' academic procrastination levels were lower than those in other grade (β =-0.12). Conclusion: It suggests that undergraduates procrastinate widely in many academic activities. Bigger and normal influence for academic by mobile-phone, higher level of computer dependence may be risk factors of procrastination, while being satisfied with grades and seniors may be protective factors.

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.
