Objective:Currently, there is a lack of targeted training programs for resident physicians in cardiopulmonary resuscitation (CPR) in China. This study aims to establish a stratified training indicator system for resident physicians in CPR that is in line with the medical realities in China.Methods:Expert consultation questionnaires were designed through literature review, group discussions, and surveys. Two rounds of expert consultation were conducted using the modified Delphi method to develop the stratified training indicator system for resident physicians in CPR. Statistical analysis was performed using SPSS 26.0 software and Kendall's coefficient of concordance was used to assess the consistency of expert opinions.Results:A total of 15 experts participated in two rounds of questionnaire consultation, with a positive coefficient of 100.00% and an authority coefficient of 0.91, indicating high expert engagement and authority, thus ensuring the credibility of the results. The coefficient of variation for expert ratings in the first round of questionnaire consultation ranged from 0 to 0.40, with a concordance coefficient of 0.22 ( P<0.001). In the second round of questionnaire consultation, the coefficient of variation for expert ratings ranged from 0 to 0.24, with a concordance coefficient of 0.25 ( P<0.001). The Kendall's coefficient of concordance for expert opinions showed statistically significant differences in both rounds of questionnaire consultation, indicating consensus among experts and reliable results. This system consisted of 6 primary indicators and 32 secondary indicators. Conclusions:Based on the modified Delphi method, this study established a stratified training indicator system for resident physicians in CPR. In the future, based on the research findings, CPR training programs adapted to the medical realities in China will be developed and promoted to validate their scientific and practical value.

Objective To explore the clinical effect of totally laparoscopic total gastrectomy combined with hand-sewn esophagojejunos-tomy for gastric cancer.Methods Ninety cases of gastric cancer patients were seleted,of which 45 cases undergoing Roux-en-Y esophagoje-junostomy for digestive tract reconstruction were set as the control group,while 45 cases undergoing hand-sewn esophagojejunostomy for digestive tract reconstruction were set as the observation group.Patients in the control group underwent laparoscopic-assisted total gastrectomy combined with Roux-en-Y esophagojejunostomy to reconstruct digestive tract,while patients in the observation group underwent totally laparoscopic total gastrectomy combined with hand-sewn esophagojejunostomy to reconstruct digestive tract.The perioperative indicators and complications of patients in the two groups were compared.Results The surgical time,time of esophagojejunostomy,and time to get out of bed after surgery of patients in the observation group were significantly shorter than those in the control group(P<0.05),the pain score 24 hours after surgery was significantly lower than that in the control group(P<0.05).There was no statistically significant difference between the two groups in terms of the incidence of complications or Clavien-Dindo grading(P>0.05).Conclusion Hand-sewn esophagojejunostomy for digestive tract reconstruction has a good clinical effect in gastric cancer during totally laparoscopic total gastrectomy.It can shorten the surgical time and time of esophagojejunostomy,reduce postoperative pain,and accelerate postoperative recovery,whose safety is comparable to Roux-en-Y esophagojejunostomy.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

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.
