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 compare the clinical features and the outcome of in-hospital mortality between patients with myocardial infarction with non-obstructive coronary arteries(MINOCA)and myocardial infarction with obstructive coronary artery disease (MI-CAD). Methods: This is a retrospective study. The clinical data of acute myocardial infarction (AMI) patients admitted to Qilu Hospital of Shandong University from January 2017 to May 2021, who underwent coronary angiography, were collected. Patients were divided into MINOCA group and MI-CAD group according to the degree of coronary stenosis (<50% or ≥50%). Baseline clinical characteristics, electrocardiograph during hospitalization, myocardial bridge, length of stay in hospital, discharge medication and the outcome of in-hospital mortality were collected and compared between the two groups. Univariate and multivariate logistic regression analysis was used to screen the related factors of MINOCA and the factors predicting the nosocomial death outcome of patients with AMI. Results: A total of 3 048 AMI patients were enrolled, age was 62 (54, 69) years, 741 (24.3%) patients were women including 165 patients (5.4%) in the MINOCA group and 2 883 patients (94.6%) in the MI-CAD group. Compared with MI-CAD patients, MINOCA patients were younger, had a higher proportion of females and a higher incidence of NSTEMI, and had a lower history of smoking, diabetes, coronary heart disease and myocardial infarction. Baseline inflammatory markers such as neutrophil count, monocyte count, neutrophil count/lymphocyte count (NLR), and monocyte count/high-density lipoprotein count (MHR) were lower, creatinine, N-terminal pro-brain B-type Natriuretic peptides (NT-proBNP), creatine kinase-MB, hypersensitive troponin I, fibrinogen, baseline blood glucose levels were lower, high-density lipoprotein cholesterol was higher, and the incidence of myocardial bridge, arrhythmia, tachycardia and atrial fibrillation was higher (P<0.05). The application rates of calcium antagonists and non-vitamin K antagonists oral anticoagulants were higher in MINOCA group (P<0.05), and there was no statistical difference in hospitalization days and in-hospital death between the two groups (P>0.05). Multiple logistic regression analysis showed that young age, female, non-smoker, no history of coronary heart disease and low MHR were risk factors of MINOCA (P<0.05). MINCOA was not associated with higher in-hospital death (P>0.05). Patients with AMI and a history of coronary heart disease, chronic renal failure, higher baseline blood glucose, higher NLR, and higher D-dimer were risk factors of in-hospital death (P<0.05). Conclusions: Compared with MI-CAD patients, MINOCA patients are younger, more likely to be female and non-smokers and on history of coronary heart disease, and have lower baseline MHR. MINOCA is often associated with myocardial bridge and atrial fibrillation. The incidence of in-hospital death in MINCOA patients is similar as in MI-CAD patients.

Objective:To analyze the compatibility rules of prescriptions containing Forsythiae Fructus based on data mining and explore the anti-inflammatory mechanism of Forsythiae Fructus based on network pharmacology，so as to provide reference for the rational clinical application of Forsythiae Fructus and the development of health foods and new Chinese medicines. Method:The prescriptions containing Forsythiae Fructus in the Dictionary of Traditional Chinese Medicine Prescriptions were collected，based on which a clinical prescription database was constructed. The Chinese herbs combined with Forsythiae Fructus and the corresponding indications were subjected to frequency statistics，association rule analysis，and complex network analysis using SPSS Statistics 26，IBM SPSS Modeler 18.0，and Gephi 9.2. The active components and targets of Forsythiae Fructus for anti-inflammation were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP），BATMAN-TCM，and SEA，and the targets related to anti-inflammation from GeneCards，Online Mendelian Inheritance in Man （OMIM），CTD，and GenCLiP3. Following the analysis of protein-protein interactions （PPI） with STRING，a PPI network was constructed. The enrichment analysis was performed using Metascape，and the active component-anti-inflammation target-signaling pathway network of Forsythiae Fructus was constructed by Cytoscape 3.8.2. Result:According to the inclusion and exclusion criteria，2 245 prescriptions containing Forsythiae Fructus were harvested，involving 512 Chinese herbs，with a total usage frequency of 27 314. The Chinese herbs that were most frequently combined with Forsythiae Fructus （>800 times） were Glycyrrhizae Radix et Rhizoma （1 483 times），Scutellariae Radix （964 times），and Angelicae Sinensis Radix （842 times）. Hence，the herbal pairs "Forsythiae Fructus-Scutellariae Radix" and "Forsythiae Fructus-Angelicae Sinensis Radix" were further explored. The prescriptions containing Forsythiae Fructus could be utilized for the treatment of 29 kinds of diseases，and three representative disease categories including "carbuncle，gangrene，sores and ulcers"，"ophthalmic diseases and syndromes" and "epidemic diseases" are selected for data mining. There were 19 association rules obtained with "Forsythiae Fructus-Glycyrrhizae Radix et Rhizoma-Lonicerae Japonicae Flos-Angelicae Sinensis Radix" as the core herb combination for "carbuncle，gangrene，sores and ulcers". The clustering analysis revealed one multi-herb clustering group，four herbal pairs，and single herb Lonicerae Japonicae Flos，the complex network analysis four herbal modules，and the factor analysis six common factors. There were 23 association rules obtained with "Forsythiae Fructus-Glycyrrhizae Radix et Rhizoma-Scutellariae Radix-Angelicae Sinensis Radix" as the core herb combination for "ophthalmic diseases and syndromes". The clustering analysis revealed two multi-herb clustering groups and four herbal pairs，the complex network analysis four herbal modules，and the factor analysis five common factors. There were 28 association rules obtained with "Forsythiae Fructus-Glycyrrhizae Radix et Rhizoma-Menthae Haplocalycis Herba-Lonicerae Japonicae Flos" as the core herb combination for "epidemic diseases". The clustering analysis revealed three multi-herb clustering groups，one herbal pair，and two single herbs Forsythiae Fructus and Glycyrrhizae Radix et Rhizoma，the complex network analysis four herbal modules，and the factor analysis five common factors. As demonstrated by network pharmacology-based analysis，the core anti-inflammation components of Forsythiae Fructus were quercetin，luteolin，and kaempferol，and the core targets were phosphoinositide-3-kinase regulatory subunit 1 （PIK3R1），protein kinase B 1 （Akt1），and epidermal growth factor receptor（EGFR）. The biological pathways were mainly concentrated in proteoglycans in cancer，pathways in cancer，and PI3K/Akt signaling pathway，with such functions as inhibition of transcription factors，regulation of enzyme activity，and inflammation-related gene expression involved. Conclusion:This study employed a variety of data mining techniques to objectively，intuitively，and scientifically uncover the compatibility rules of Forsythiae Fructus in the treatment of high-frequency diseases. It has been found that Forsythiae Fructus is often combined with heat-clearing herbs，tonifying herbs，exterior-releasing herbs，and blood-activating and stasis-resolving herbs for diverse diseases and syndromes. Under the premise of clearing heat and removing toxin，reinforcing healthy Qi and dredging stagnation are also emphasized. According to the degree of internal heat exuberance，the heat-clearing herbs with different merits are combined. This study has revealed the unique advantages of Forsythiae Fructus in the treatment of specific diseases and syndromes as well as its multi-component，multi-target，and multi-pathway mechanisms in anti-inflammation，breaking through the limitations in modern clinical and experimental research of Forsythiae Fructus. These findings are of great significance for guiding the rational clinical application of Forsythiae Fructus and the development of health foods and new Chinese medicines，thus better accelerating the development of Chinese medicine health industry.

OBJECTIVE: To establish a secondary hemophagocytic lymphohistiocytosis(HLH) mouse model, and to investigate the effect of ruxolitinib on the disease manifestation of model mice. METHODS: Wild type C57BL/6 mice were randomly divided into 4 groups: two groups of mice were intraperitoneally injected with CpG oligodeoxynucleotide 1826 (CpG-ODN1826) every other day to induce HLH, and other two groups were control groups. One group of the CpG-ODN1826 groups and one of the control groups were given ruxolitinib, and other two groups were given the same amount of PBS. Blood samples, serum ferritin and hepatic/spleen weights of experimental mice were detected and serum cytokine levels were measured by ELISA. RESULTS: Compared with the control groups, the levels of white blood cells, hemoglobin and platelets in the CpG-ODN1826 groups were significantly lower (P＜0.05); and liver/body weight, spleen/body weight, serum ferritin, sCD25, IL-10, IL-1β, IFN-Ƴ, IL-12p70, GM-CSF, TNF-α and IL-18 levels significantly increased (P＜0.05). There was no significant difference in the levels of IL-2, IL-4, IL-5, IL-6, IL-22, IL-13, IL-27 and IL-23 between the two groups (P＞0.05). The spleen in CpG group had disordered internal structure, expanding red pulp and hyperplastic nucleated cells. The liver had severe perivascular inflammations. The spleen/weight of the ruxolitinib-treated mice in the CpG-ODN1826 group was significantly smaller than that of the unapplied ruxolitinib (P＜0.05). CONCLUSION The CpG-ODN1826 can induce secondary HLH symptoms in wild type C57BL/6 mice. Ruxolitinib can alleviate the symptoms of splenomegaly in HLH model mice.

OBJECTIVE: To Establish the shielding threshold value of TP antibody ELISA for unpaid blood donors, so as to shield true positive blood donors from returning to team management. METHODS: The real serological status of 517 samples with anti-TP ELISA reactivity was determined by confirmation test of Treponema pallidum particle agglutination (TPPA). The shielding threshold of TP antibody was preliminarily determined by using 99% specificity of ROC and 95% positive predictive value of percentile method, respectively. 283 TP antibody reactivity specimens routinely tested in our laboratory were selected to determine the applicability of the initial shielding values obtained by the two methods, and finally to determine the shielding threshold values of TP antibody donors. RESULTS: The specific S/CO values of reagent A 99% were 13.33-16.18, that of reagent B 99% was 6.34, that of reagent B 99% was 13.17-19.85, and that of 95% was 6.62. Empirical evidence: 99% specific threshold shielding true positive rates of reagents A and B were 100%, 95% positive expected value shielding true positive rates were 98.4%, 99%. Final determination of 99% specific shielding threshold as a low value of blood donors shielding threshold. The shielding limits of reagent A and B were 13.33 and 13.17. CONCLUSION The shielding threshold of TP antibody ELISA for blood donors established in this study can help to reduce the number of blood donors returning to team management.
