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 describe the current state of research and future research hotspots through a metrological analysis of the literature in the field of forensic anthropological remains identification re-search.Methods The data retrieved and extracted from the Web of Science Core Collection (WoSCC),the core database of the Web of Science information service platform (hereinafter referred to as "WoS"),was used to analyze the trends and topic changes in research on forensic identification of human re-mains from 1991 to 2022.Network visualisation of publication trends,countries (regions),institutions,authors and topics related to the identification of remains in forensic anthropology was analysed using python 3.9.2 and Gephi 0.10.Results A total of 873 papers written in English in the field of forensic anthropological remains identification research were obtained.The journal with the largest number of publications was Forensic Science International (164 articles).The country (region) with the largest number of published papers was China (90 articles).Katholieke Univ Leuven (Netherlands,21 articles) was the institution with the largest number of publications.Topic analysis revealed that the focus of forensic anthropological remains identification research was sex estimation and age estimation,and the most commonly studied remains were teeth.Conclusion The volume of publications in the field of forensic anthropological remains identification research has a distinct phasing.However,the scope of both international and domestic collaborations remains limited.Traditionally,human remains identifica-tion has primarily relied on key areas such as the pelvis,skull,and teeth.Looking ahead,future re-search will likely focus on the more accurate and efficient identification of multiple skeletal remains through the use of machine learning and deep learning techniques.

Novel coronavirus Omicron variant infection can cause severe illness and even death in certain populations. Omicron variant infection may lead to systemic inflammatory response, coagulation disorder, multi-organ dysfunction and other pathophysiological changes, which are different from other Novel coronavirus variants to a certain extent, so therapeutic strategies should not be the same. The National Medical Center for Major Public Health Events invited experts in fields of infectious diseases, respiratory medicine, intensive care, pediatrics and fever clinic to develop this quick guideline based on the current best evidence and extensive clinical practices. This quick guideline aims to standardize the diagnosis and treatment of novel coronavirus Omicron infection, and to improve the disease management abilities of clinicians.

Objective:To evaluate the effects of the cassette 14C-urea breath test kit, scintillation sampling bottle (solid-state scintillation method) and liquid scintillation 14C-urea breath test kit in the diagnosis of Helicobacter pylori ( H. pylori) infection. Methods:From January 7 to October 28, 2020, 239 patients were enrolled who visited Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, the Second Affiliated Hospital of Zhejiang University School of Medicine and the First Affiliated Hospital of Nanchang University. All subjects first received 14C-urea breath test.Within >1 to <7 days after gas collection, mucosal tissues were taken under gastroscopy for gold standard test, including biopsy and rapid urease test (RUT). If both biopsy and RUT indicated H. pylori positive, the result of gold standard test was H. pylori positive, and if both were negative, the result of gold standard test was H. pylori negative. If the results of biopsy and RUT were inconsistent, they were not included in the subsequent analysis. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were analyzed. The safety of the test was evaluated by whether there were any adverse events during the test. Descriptive methods were used for statistical analysis. Results:Among the 239 subjects, 12 cases did not complete the test, 227 subjects finally completed the test. The test completion rate was 95.0% (227/239). No.008 patient was only included in the analysis of cassette 14C-urea breath test kit and scintillation sampling bottle because of lacking the result of liquid scintillation breath test. The results of gold standard test showed that among 227 patients, 87 cases were H. pylori positive, 118 cases were H. pylori negative. The results of biopsy and RUT were inconsistent in 22 cases, so they were not included in the subsequent analysis. Excluding No.008 patient, the results of gold standard test showed that 86 cases were H. pylori positive and 118 cases were negative. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of cassette 14C-urea breath test kit, scintillation sampling bottle, and the liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were 91.9%, 100.0%, 96.6%, 100.0% and 94.4%, respectively; 95.4%, 97.5%, 96.6%, 96.5% and 96.6%, respectively; and 96.5%, 99.2%, 98.0%, 98.8% and 97.5%, respectively. Only one adverse event (right upper abdominal pain after eating) occurred. Combined with the patients condition, the adverse event was determined as the onset of chronic cholecystitis and it might not be related to the test medication. Conclusions:Cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit have reliable performance, good safety, and high sensitivity, specificity and accuracy in the diagnosis of H. pylori infection, which are worthy of clinical application.

Objective: To explore the safety and effectiveness of stereotactic body radiation therapy (SBRT) for oligometastases from colorectal cancer (CRC). Methods: This is a prospective, single-arm phase Ⅱ trial. Patients who had histologically proven CRC, 1 to 5 detectable liver or lung metastatic lesions with maximum diameter of any metastases ≤5 cm were eligible. SBRT was delivered to all lesions. The primary endpoint was 3-year local control (LC). The secondary endpoints were treatment-related acute toxicities of grade 3 and above, 1-year and 3-year overall survival (OS) and progression free survival (PFS). Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: Petients from 2016 to 2019 who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Forty-eight patients with 60 lesions were enrolled, including 37 liver lesions and 23 lung lesions. Forty-six patients had 1 or 2 lesions, with median diameter of 1.3 cm, the median biologically effective dose (BED(10)) was 100.0 Gy. The median follow-up was 19.5 months for all lesions. Twenty-five lesions developed local failure, the median local progression free survival was 15 months. The 1-year LC, OS and PFS was 70.2% (95% CI, 63.7%~76.7%), 89.0% (95% CI, 84.3%~93.7%) and 40.4% (95%CI, 33.0%~47.8%). The univariate analysis revealed that planning target volume (PTV) and total dose were independent prognostic factors of LC (P<0.05). For liver and lung lesions, the 1-year LC, OS and PFS was 58.7% and 89.4% (P=0.015), 89.3% and 86.5% (P=0.732), 30.5% and 65.6% (P=0.024), respectively. No patients developed acute toxicity of grade 3 and above. Conclusion: SBRT is safe and effective treatment method for oligometastases from CRC under precise respiratory motion management and robust quality assurance.

Objective: To explore the types and clinical characteristics of chronic rhinosinusitis with nasal polyps (CRSwNP) based on artificial intelligence and whole-slide imaging (WSI), and to explore the consistency of the diagnostic criteria of the Japanese epidemiological survey of refractory eosinophilic chronic rhinosinusitis (JESREC) in Chinese CRSwNP patients. Methods: The data of 136 patients with CRSwNP (101 males and 35 females, aging 14 to 70 years) who underwent endoscopic sinus surgery from 2018 to 2019 in the Department of Otorhinolaryngology Head and Neck Surgery, the Third Affiliated Hospital of Sun Yat-sen University were analysed retrospectively. The preoperative clinical characteristics of patients were collected, such as visual analogue scale (VAS) of nasal symptoms, peripheral blood inflammatory cell count, total immunoglobulin E (IgE), Lund-Kennedy score and Lund-Mackay score. The proportion of inflammatory cells such as eosinophils, lymphocytes, plasma cells and neutrophils were calculated on the WSI of each patient through artificial intelligence chronic rhinosinusitis evaluation platform 2.0 (AICEP 2.0), and the specific type of nasal polyps was then obtained as eosinophilic CRSwNP (eCRSwNP) or non-eosinophilic CRSwNP (non-eCRSwNP). In addition, the JESREC diagnostic criteria was used to classify the nasal polyps, and the classification results were compared with the current gold standard for nasal polyps diagnosis (pathological diagnosis based on WSI). The accuracy, sensitivity and specificity of the diagnostic criteria of JESREC were evaluated. The data were expressed in M (Q₁, Q₃) and statistically analyzed by SPSS 17.0. Results: There was no significant difference between eCRSwNP and non-eCRSwNP in age distribution, gender, time of onset, total VAS score, Lund-Kennedy score or Lund-Mackay score. However, there was a significant difference in the ratio of nasal polyp inflammatory cells (eosinophils 40.5% (22.8%, 54.7%) vs 2.5% (1.0%, 5.3%), neutrophils 0.3% (0.1%, 0.7%) vs 1.3% (0.5%, 3.6%), lymphocytes 49.9% (39.3%, 65.9%) vs 82.0% (72.8%, 87.5%), plasma cells 5.1% (3.6%, 10.5%) vs 13.0% (7.4%, 16.3%), χ² value was 9.91, 4.66, 8.28, 5.06, respectively, all P<0.05). In addition, eCRSwNP had a significantly higher level of proportion of allergic symptoms (nasal itching and sneezing), asthma, peripheral blood eosinophil and total IgE (all P<0.05). The overall accuracy, sensitivity and specificity of the JESREC diagnostic criteria was 74.3%, 81.3% and 64.3%, respectively. Conclusions: The eCRSwNP based on artificial intelligence and WSI has significant high level of allergic symptoms, asthma, peripheral blood eosinophils and total IgE, and the percentages of inflammatory cells in nasal polyps are different from that of non-eCRSwNP. The JESREC diagnostic criteria has good consistency in our research.

Objective:To investigate the application value of Da Vinci robotic surgical system in radical resection of perihilar cholangiocarcinoma (pCCA).Methods:The retrospective and descrip-tive study was conducted. The clinicopathological data of 10 patients undergoing Da Vinci robotic radical resetion of pCCA in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from September 2018 to March 2021 were collected. There were 6 males and 4 females, aged (58±7)years. Observtaion indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. The patients were followed up by telephone interview and outpatient service to detect survival of patients and tumor recurrence up to June 2021. Measurement data with normal distribution were expressed as Mean± SD, and measurement data with skewed distribu-tion were represented as M(range). Count data were represented as absolute numbers. Results:(1) Surgical situations: 10 patients underwent Da Vinci robotic radical resection of pCCA succe-ssfully, without conversion to laparotomy or intraoperative blood transfusion. The operation time of 10 patients was (465±87)minutes, and the volume of intraoperative blood loss was (167±81)mL. Of the 10 patients, 1 case of Bismuth type Ⅲb had a positive surgical margin and the remaining 9 cases had R 0 resection. (2) Postoperative situations: the time to gastric tube extraction was (2.3±1.9)days, and the duration of postoperative hospital stay of the 10 patients was (19.9±9.0)days. Among the 10 patients, there was no second operation or perioperative death. Of the 10 patients, 6 cases had perioperative complications, including 5 cases wth pleural effusion, 3 cases with peritoneal effusion, and 1 case with intestinal obstruction, some patients had multiple complications. After symptomatic conservative treatment, pleural effusion and peritoneal effusion disappeared and intestinal obstruction was improved. None of the 10 patients had serious complica-tions such as bleeding, biliary fistula or intestinal fistula. (3) Follow-up: 10 patients were followed up for 3-20 months, with a median follow-up time of 11 months. During the follow-up, 3 of 10 patients had tumor recurrence which occurred in intrahepatic bile duct of residual liver, and no implantation metastasis was found in the rest of abdominal cavity. Of the 7 unrecurrent patients, 1 case died of gastrointestinal bleeding and multiple organ failure. Nine of 10 patients survived well. Conclusion:The Da Vinci robotic surgical system used for radical operation of pCCA is feasible.
