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.

Gallbladder benign lesion is a common clinical disease. Some benign gallbladder disease may progress to malignant tumors, but its pathogenesis and malignant transformation tendency have not been fully elucidated. The treatment of benign gallbladder lesions is still controversial: some scholars advocate cholecystectomy to prevent malignant changes; others believe that some benign gallbladder lesions can be followed up closely. Laparoscopic cholecystectomy is the main method for the treatment of benign gallbladder diseases. But aggressive surgery to treat benign gallbladder diseases can possibly cause damage to patients. This article reviews the clinical manifestations, imaging manifestations and progress in diagnosis and treatment of benign gallbladder lesions.

Objective:To explore influencing factors of poor prognosis in patients with severe trauma,and to analyze distribu-tion characteristics of adverse prognostic factors in patients with different early peripheral blood lymphocyte levels based on potential categories.Methods:A total of 174 patients with severe trauma treated in Mianyang Central Hospital from September 2020 to Septem-ber 2022 were selected.According to condition of massive blood transfusion or death within 24 hours after admission,patients were divided into:good prognosis group(n=136)and poor prognosis group(n=38).Clinical data of two groups were compared,multivariate Logistic regression analysis was used to analyze factors affecting poor prognosis,and cluster analysis and potential classification were used to analyze distribution characteristics of adverse prognostic factors in patients with different early peripheral blood lymphocyte levels.Results:Multivariate Logistic regression analysis results showed decrease of Glasgow coma scale(GCS),prolongation of acti-vated partial thromboplastin time(APTT),increase of D-dimer(D-D),decrease of fibrinogen(Fib),increase of fibrinogen degrada-tion products(FDP),increase of neutrophil/lymphocyte ratio(NLR)and decrease of lymphocyte level were factors influencing poor prognosis(P<0.05).Cluster analysis results showed that risk of poor prognosis was obviously clustered,and patients could be divided into poor prognosis high risk group(lymphocyte level≤0.90×109 L-1,n=72)and low risk group(lymphocyte level>0.90×109 L-1,n=102).Incidence of poor prognosis in high risk group[33.33%(24/72)]was significantly higher than that in low risk group[13.73%(14/102)](P<0.05).Potential category analysis results showed that there were three potential category distribution patterns in poor prognosis high risk group and low risk group.Proportion of"unelevated distribution of D-D in patients with low GCS score"in high risk group was significantly higher than that in low risk group,and proportion of"distribution of less risk factors"in high risk group was sig-nificantly lower than that in low risk group(P<0.05).There was no significant difference in proportion of elevated D-D distribution in patients with low GCS score between two groups(P>0.05).Conclusion:Decrease of GCS score,prolongation of APTT and increase of D-D are all associated with poor prognosis in patients with severe trauma.Patients with lymphocyte level≤0.90×109 L-1 have a higher risk of poor prognosis,and main influencing factors are"non-elevated distribution of D-D in patients with low GCS score".

This study, in collaboration with 12 participating units, aims to establish a high-quality, multidimensional cohort comprising 20 000 naturally conceived families and assisted reproductive families. The study involves long-term follow-up of parents and offspring, with corresponding biological samples collected at key time points. Through multi-omics testing and analysis, the study aims to conduct multi-omics big data research across the entire maternal and infant life cycle. The goal is to identify new biomarkers for maternal and infant diseases and provide scientific evidence for risk prediction related to maternal diseases and neonatal health.

Prevention and treatment of complications after liver transplantation play a significant role in maintaining liver graft function and improving clinical prognosis of the recipients. Neutrophil extracellular trap (NET) are fibrous net-like structures composed of DNA as the skeleton and histones and granular proteins released by activated neutrophils. Studies have shown that the activation of neutrophils and the release of NET in donor liver after liver transplantation are involved in the incidence of multiple liver transplantation-related complications including ischemia-reperfusion injury, acute rejection, acute liver failure and recurrence of hepatocellular carcinoma, etc. In this article, the effect of NET on the complications after liver transplantation was mainly assessed, and research progress on NET as a potential target for the prevention and treatment of complications after liver transplantation was reviewed, aiming to provide reference for the prevention and treatment of complications after liver transplantation, enhance clinical efficacy of liver transplantation and improve clinical prognosis of the recipients.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

AIM: To evaluate the bioequivalence of the test and reference formulations of mycophenolate mofetil capsule in Chinese healthy male subjects under fasting and fed conditions. METHODS: This was a 2-treatment, 2-sequence, 4-period, fully replicated crossover study that included 80 Chinese healthy male subjects (40 subjects in the fasting group and 40 subjects in the fed group, respectively). Subjects were assigned to receive a single oral administration of the test or reference formulation at a dose of 0.25 g in each period. The plasma concentration of mycophenolate mofetil (MMF) and metabolite mycophenolic acid (MPA) were analyhed by LC-MS/MS. The major pharmacokinetic parameters of MMF and MPA were calculated using non-compartmental analysis by WinNonlin 8.0. The statistical analysis was performed by SAS 9.4. Average bioequivalence (ABE) analysis was applied where it has been demonstrated that the within-subject standard deviation of the reference formulation (S

In bleeding events caused by various reasons, coagulation dysfunction due to massive consumption or loss of coagulation factors is often life-threatening. In recent years, medical evidence of using human fibrinogen concentrate to prevent or treat bleeding has emerged, providing more options for clinical treatment of bleeding. In this paper, the stability, pharmacokinetics and safety of human fibrinogen, as well as the latest advances in its clinical application in obstetrics, cardiac surgery and traumatic massive hemorrhage were summarized, and new reasonable suggestions for clinical application of human fibrinogen were also put forward.

Objective:To evaluate the efficacy and safety profile of ixazomib/lenalidomide/dexamethasone (IRd) in Chinese patients with relapsed/refractory multiple myeloma (MM) .Methods:This study comprising 14 medical centers in China included patients with relapsed/refractory MM who received at least. Ixazomib at an initial oral dose of 4 mg was administered. Seven patients had dose adjustment to 3 mg at the time of first dose. The lenalidomide doses were adjusted according to creatinine clearance rate. The efficacy and safety were evaluated every cycle.Results:In the study cohort of 74 patients, the median age was 65 years and 11 (14.9% ) patients received over three lines of therapy. Overall response rate (ORR) was 54.1% (40/74) , and 7 (9.5% ) , 14 (18.9% ) , and 19 (25.7% ) patients achieved stringent complete response or complete response, very good partial response, and partial response, respectively. The median progression-free survival and overall survival were 9.9 and 20 months, respectively. The median time to response was 1 month. The efficacy and survival outcome were similar to those reported in the Tourmaline-MM1 China Continuous Study. The ORR of patients refractory to bortezomib, lenalidomide, and bortezomib plus lenalidomide were 52.0% (13/25) , 57.1% (4/7) , and 33.3% (6/18) , respectively. The rate of grade 3-4 adverse events was 36.5% (27/74) . Common hematological toxicities were anemia, thrombocytopenia, lymphopenia, and neutropenia. Common non-hematological toxicities were fatigue, gastrointestinal symptoms, and infections. Two cases of grade 3 peripheral neuropathy were reported. The patients eligible for the Tourmaline-MM1 China Continuous Study had a higher ORR than the ineligible patients [77.8% (14/18) vs 46.4% (26/56) , P=0.020]. There was no difference in the rate of grade 3-4 adverse events [33.3% (6/18) vs 37.5% (21/56) , P=0.749]. Conclusion:The IRd regimen had good efficacy and acceptable toxicity in Chinese patients with relapsed/refractory MM.
