Objective:To explore the training method for personalized eyebrow shape design before eyebrow transplantation surgery and to evaluate its effectiveness.Methods:Thirty physicians with similar foundational knowledge in facial aesthetic design and equivalent educational backgrounds were prospectively selected from the Second Hospital of Lanzhou University and Beijing Biliansheng Medical Beauty Clinic from January to December 2023. All the physicians were right-handed. Based on prior experience in eyebrow transplantation surgery, they were divided into two groups: an observation group [ n=20; 10 males, 10 females; aged (27.8±3.9) years] without experience in personalized eyebrow transplantation surgery, and a control group [ n=10; 5 males, 5 females; aged (29.6±4.0) years] with at least 2 years of experience in personalized eyebrow transplantation surgery. All the physicians received 2 hours of theoretical instruction on personalized eyebrow shape design and 8 hours of simulated operation training. Differences in personalized eyebrow design scores between the two groups were compared before and after training. After the assessment, physicians in the observation group performed eyebrow shape design on 20 eyebrow transplantation patients with randomly assigned face shapes, and patient satisfaction was evaluated. Results:Before training, personalized eyebrow design scores were 1.16±0.29 for the observation group and 3.75±0.22 for the control group, showing a statistically significant difference ( P<0.001). After operation training, the scores were 4.51±0.11 for the observation group and 4.89±0.08 for the control group, with no statistically significant difference ( P>0.05). The difference between pre- and post-training scores within the observation group was statistically significant ( P<0.05). Physicians in the observation group designed eyebrow shapes for male and female patients with various face shapes. Immediately after surgery, 80% (16/20) of patients were very satisfied, and 20% (4/20) were satisfied. Conclusion:After training of combined theoretical lectures, simulated practice, and hands-on patient design, physicians in the observation group demonstrate improved ability in personalized eyebrow shape design and achieve high patient satisfaction.

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.

Objective To construct a prediction model for postoperative healthcare-associated infection(HAI)in elderly patients with hip fracture,analyze the economic burden,provide a reference and basis for the development of clinical prevention and control programs.Methods 627 elderly patients who underwent hip fracture surgery in a hospital from January 1,2017 to May 31,2023 were selected as the study subjects.Patients were randomly divided into a modeling group and a validation group at a 7:3 ratio.A logistic regression prediction model was constructed based on data from the modeling group,the discriminant and consistency of the model were evaluated by receiver ope-rating characteristic(ROC)curve and Hosmer-Lemeshow test,and the direct economic burden of postoperative HAI in patients was analyzed with 1∶1 propensity score matching(PSM).Results The incidence of postoperative HAI in elderly patients with hip fracture surgery was 12.1％,with pulmonary infection being the most common(52.6％).Logistic regression analysis showed that male,old age,perioperative disturbance of consciousness,gradeⅣ of American Society of Anesthesiologists(ASA)classification,low albumin level,and intensive care unit(ICU)admission were all independent risk factors for postoperative HAI in patients(all P＜0.05).There was good model discrimination and consistency between the training and validation groups in predicting the risk of postoperative HAI.The direct economic burden of postoperative HAI in patients was 7 927.4 Yuan,of which the burden of wes-tern medicine was the largest(3 139.7 Yuan).HAI prolonged patients hospitalization time by 3.6 days.Conclusion Postoperative HAI increases the economic burden of patients,the nomogram model constructed in this study can effectively predict the risk of postoperative HAI in patients,which can provide a basis for the early identification,as well as the implementation of targeted preventive and diagnostic measures for high-risk patients in the clinic.

Objective:To investigate the association of serum levels of tumor necrosis factor receptor-related factor 6(TRAF6)and histone deacetylase 3(HDAC3)with severity of coronary artery disease and prognosis in patients with acute myocardial infarction(AMI).Methods:A total of 122 AMI patients admitted Macheng Traditional Chinese Medicine Hospital between July 2019 and December 2020 were selected,divided into low score group(n=73,＜20 points)and high score group(n=49,≥20 points)according to Gensini score.Association of serum levels of TRAF6 and HDAC3 with Gensini score was analyzed by Pearson method.According to survival condition during hospitalization within 28d,they were divided into survival group(n=85)and death group(n=37).Cox regression model was used to analyze the influencing factors for death within 28d in AMI patients;receiver operating charac-teristic(ROC)curve was used to analyze the predictive efficacy of TRAF6 and HDAC3 for death within 28d in AMI patients.Results:Patients in high score group had significant higher serum levels of TRAF6[(6.01±2.39)μg/ml vs.(5.06±1.74)μg/ml,P=0.012]and HDAC3[(4.14±1.94)ng/ml vs.(2.87±1.37)ng/ml,P＜0.001]compared with low score group.Pearson correlation analysis indicated that serum levels of TRAF6 and HDAC3 were positively correlated with Gensini score(r=0.879,0.837,P＜0.001 all).Patients in death group had significant higher serum levels of TRAF6[(6.89±1.67)μg/ml vs.(4.81±1.24)μg/ml,P＜0.001]and HDAC3[(5.37±1.77)ng/ml vs.(2.52±0.76)ng/ml,P＜0.001]compared with those in survival group.Cox regression analysis indicated that Gensini score[HR=1.857,95％CI 1.259～2.737,P=0.001],TRAF6[HR=1.659,95％CI 1.083～2.543,P=0.022],HDAC3[HR=1.779,95％CI 1.192～2.653,P=0.004]were independent risk factors for death within 28d in AMI patients.ROC curve analysis indicated that AUC of TRAF6,HDAC3 and their combina-tion predicting death within 28d in AMI patients was 0.862,0.859 and 0.971 respectively,and AUC of combination was significantly higher than those of TRAF6 and HDAC3 alone(Z=2.535,2.032,P=0.011,0.042).Conclu-sion:Serum levels of TRAF6 and HDAC3 are closely related to severity of coronary artery disease and prognosis in AMI patients,and dual combination possesses good predictive value for prognosis in AMI patients.
