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.

Persistent neurogenesis exists in the subventricular zone (SVZ) of the ventricles and the subgranular zone (SGZ) of the dentate gyrus of the hippocampus in the adult mammalian brain. Adult endogenous neurogenesis not only plays an important role in the normal brain function, but also has important significance in the repair and treatment of brain injury or brain diseases. This article reviews the process of adult endogenous neurogenesis and its application in the repair of traumatic brain injury (TBI) or ischemic stroke, and discusses the strategies of activating adult endogenous neurogenesis to repair brain injury and its practical significance in promoting functional recovery after brain injury.

With continuous discovery of tumor immune targets and continuous changes in antibody research and development technology, antibody drugs are becoming more and more widely used in clinical practice. However, some targets are not only expressed on tumor cells, but also on red blood cells. Therefore, the clinical application of antibodies against the corresponding targets may interfere with the detection of blood transfusion compatibility, resulting in difficulty in blood matching or delay of blood transfusion. This consensus summarizes the current solutions for the interference of CD38 monoclonal antibody (CD38 mAb) in transfusion compatibility testing. After analyzing the advantages and disadvantages of different methods, polybrene and sulfhydryl reducing agents [dithiothreitol (DTT) or 2-mercaptoethanol (2-Me)], as a solution for CD38 mAb interference in blood compatibility testing, are recommended for Chinese patients, so as to eliminate blood transfusion interference produce by CD38 mAb and further provide a pre-transfusion workflow for clinicians and technicians in Department of Blood Transfusion.

BACKGROUNDWhether final kissing balloon (FKB) dilatation after one-stent implantation at left-main (LM) bifurcation site remains unclear. Therefore, this large sample and long-term follow-up study comparatively assessed the impact of FKB in patients with unprotected LM disease treated with one-stent strategy.

METHODSTotal 1528 consecutive patients underwent LM percutaneous coronary intervention in one center from January 2004 to December 2010 were enrolled; among them, 790 patients treated with one drug-eluting stent crossover LM to left anterior descending (LAD) with FKB (n = 230) or no FKB (n = 560) were comparatively analyzed. Primary outcome was the rate of major adverse cardiovascular events, defined as a composite of death, myocardial infarction (MI) and target vessel revascularization (TVR).

RESULTSOverall, The prevalence of true bifurcation lesions, which included Medina classification (1,1,1), (1,0,1), or (0,1,1), was similar between-groups (non-FKB: 37.0% vs. FKB: 39.6%, P = 0.49). At mean 4 years follow-up, rates of major adverse cardiovascular events (non-FKB: 10.0% vs. FKB: 7.8%, P = 0.33), death, MI and TVR were not significantly different between-groups. In multivariate propensity-matched regression analysis, FKB was not an independent predictor of adverse outcomes.

CONCLUSIONSFor patients treated with one-stent crossover LM to LAD, clinical outcomes appear similar between FKB and non-FKB strategy.

This study summarized the experiences of disease-specific performance appraisal at tertiary hospitals in Shanghai,which was launched since year 2013 by Shanghai Hospital Development Center (SHDC). 38 tertiary hospitals in Shanghai were included in the study. A disease-specific performance appraisal system centering on quality and performance, by means of case-mix model, classified surgery management and typical disease screening, and leveraging disease and surgery difficulties analysis, and inter-hospital performance appraisal of typical diseases. This reform has established appraisal criteria of disease difficulty management,coding criteria and data norms,guiding such hospitals to consolidate their functional positioning of focusing on difficult,urgent and complicated cases in the medical service delivery system.All these efforts have paved the way for the reforms to build a hierarchical medical service system, pricing per disease, payment per disease, and consolidate performance appraisal of medical workers.

This paper uses the data collected from 138,477 patient discharge records of 37 Shanghai tertiary public hospitals in December 2013 and classifies all the records into different groups by using a localized diagnosis re-lated group tool.The coefficient of variation index ( CV) of each group was used to analyze the dispersion of average hospital cost per inpatient day for each group, in order to evaluate the suitability of diagnosis related group systems and to set the coefficients of difficulty ( relative weights) for each disease.The study has found that severity-based di-agnosis related group systems are more suitable and consistent.However, future studies should collect more detailed information on health costs in order to reflect the value of health professionals and technologies and therefore further improve diagnosis related classification and develop new systems that can be adapted to local conditions by applying the weights of different groups.

The public hospital reform is the main content of the new healthcare reform.Studying the diagnosis related group system and establishing a set of scientific and rational performance assessment, which is essential to strengthen the public hospitals'public and social benefits, improve the service capacity and enhance the specialized and delicacy management.The international diagnosis related group system localization and weight settlement have been proved suitable and consistent through the Shanghai Shenkang Hospital Development Centre.Hence, the severity-based DRGs should be introduced to reflect the actual hospitals operation and management outcome, which provides a proper guidance on the hospitals'specialized and delicacy management.

Objective: To determine the seroprevalence of Toxoplasma gondii (T. gondii) infection in dogs and cats in Zhenjiang City, Jiangsu Province, Eastern China, and to evaluate the main associated risk factors relating to exposure to T. gondii in this region. Methods: Sera from 160 dogs and 116 cats from Zhenjiang City were tested for anti-T. gondii antibodies using ELISA. The seropositivity by area of activity, sex and age was analyzed. Results: Overall, 21 dogs (13.1%) and 24 cats (20.7%) had antibodies to T. gondii. The infection rate in stray dogs (38.7%) and cats (28.6%) was significantly higher (P<0.05) than in household dogs (6.9%) and cats (18.2%). The seroprevalence in male dogs (14.8%) and cats (21.05%) were slightly higher than their female counterparts (11.4% in dogs and 20.0% in cats), but were not significantly differenent (P>0.05). A high proportion of dogs at 3 to 6 years of age were positive to T. gondii (20.0%) while cats with relatively high seropositivity rates were at 0 to 1 year of age (33.3%). Conclusions: The prevalence of T. gondii infection in dogs and cats in Zhenjiang City was high, which is probably the main source of T. gondii infection in this area.

BACKGROUNDPatients with multivessel coronary artery disease and depressed left ventricular ejection fraction (LVEF) represent a high risk group of patients for coronary revascularization. There are limited data on percutaneous coronary intervention treatment in this population.

METHODSAmong a cohort of 4335 patients with three-vessel disease with or without left main disease undergoing percutaneous coronary intervention, 191 patients had LVEF < 40% (low ejection fraction (EF)) and 4144 patients had LVEF ≥ 40%. In-hospital and long-term outcomes were examined according to LVEF.

RESULTSThe estimated two-year rates of major adverse cardiac events, cardiac death, and myocardial infarction were significantly higher in the low EF group (19.64% vs. 8.73%, Log-rank test: P < 0.01; 10.30% vs. 1.33%, Log-rank test: P < 0.01, and 10.32% vs. 2.28%, Log-rank test: P < 0.01 respectively), but there was no difference in the rates of target vessel revascularization (6.18% vs. 6.11%, Log-rank test: P = 0.96). Using the Cox proportional hazard models, LVEF < 40% was a significant risk factor for cardiac death, myocardial infarction, and major adverse cardiac events (OR (95%CI): 4.779 (2.369 - 9.637), 2.673 (1.353 - 5.282), and 1.827 (1.187 - 2.813) respectively), but was not a statistically significant risk factor for target vessel revascularization (OR (95%CI): 1.094 (0.558 - 2.147)).

CONCLUSIONAmong patients undergoing percutaneous coronary intervention for multivessel coronary artery disease, left ventricular dysfunction remains associated with further risk of cardiac death in-hospital and during long-term follow-up.
