Background: and Purpose This study aimed to investigate the association between residual inflammatory risk (RIR) and vulnerable plaques using high-resolution magnetic resonance imaging (HRMRI) in symptomatic intracranial atherosclerotic stenosis (ICAS). Methods: This retrospective study included 70%–99% symptomatic ICAS patients hospitalized from January 2016 to December 2022. Patients were classified into four groups based on high-sensitivity C-reactive protein (hs-CRP) and low-density lipoprotein cholesterol (LDL-C): residual cholesterol inflammatory risk (RCIR, hs-CRP ≥3 mg/L and LDL-C ≥2.6 mmol/L), RIR (hs-CRP ≥3 mg/L and LDL-C <2.6 mmol/L), residual cholesterol risk (RCR, hs-CRP <3 mg/L and LDL-C ≥2.6 mmol/L), and no residual risk (NRR, hs-CRP <3 mg/L and LDL-C <2.6 mmol/L). Vulnerable plaque features on HRMRI included positive remodeling, diffuse distribution, intraplaque hemorrhage, and strong enhancement. Results: Among 336 included patients, 21, 60, 58, and 197 were assigned to the RCIR, RIR, RCR, and NRR groups, respectively. Patients with RCIR (adjusted odds ratio [aOR], 3.606; 95% confidence interval [CI], 1.346–9.662; P=0.011) and RIR (aOR, 3.361; 95% CI, 1.774–6.368, P<0.001) had higher risks of strong enhancement than those with NRR. Additionally, patients with RCIR (aOR, 2.965; 95% CI, 1.060–8.297; P=0.038) were more likely to have intraplaque hemorrhage compared with those with NRR. In the sensitivity analysis, RCR (aOR, 2.595; 95% CI, 1.201–5.608; P=0.015) exhibited an additional correlation with an increased risk of intraplaque hemorrhage. Conclusion In patients with symptomatic ICAS, RIR is associated with a higher risk of intraplaque hemorrhage and strong enhancement, indicating an increased vulnerability to atherosclerotic plaques.

Objective To explore the clinical application value of deep learning image reconstruction(DLIR)-based technique for radiation dose reduction with different noise index(NI)in CT-guided percutaneous transthoracic needle biopsy(PTNB).Methods Thirty-two patients undergoing PTNB were selected,and three sets of CT images with NI of 15,30,and 45 sequentially were obtained after adjusting the puncture needle using the scanning parameters of a small range(40 mm),tube voltage 100 kV,and automatic tube cur-rent modulation(ATCM).Group A was 50％weight of adaptive statistical iterative reconstruction-Veo(ASIR-V)scanned with NI 15,and group B and C were the DLIR-high reconstructed images with NI 30 and NI 45 respectively.The CT value and standard devia-tion(SD)value of paraspinal muscles,subcutaneous fat,and arterial vessels were measured at the puncture center point and its upper and lower 10 mm sclices,respectively,and the signal-to-noise ratio(SNR)and the contrast-to-noise ratio(CNR)were also calculated.Then the images were subjectively scored by two physicians,meanwhile the effective dose(ED)among the three groups was com-pared.Results According to the subjective evaluation,the image quality of group A,B,and C all met the clinical requirement for puncture.The SD and SNR of the images in group B were better than those in groups A and C.The SD and SNR of paraspinal mus-cles and sudcutaneous fat were significantly different between groups A and B,and between groups B and C(P＜0.05),however those of paraspinal muscles and subcutaneous fat between groups A and C were not significant.The differences in ED among the three groups were all statistically significant(P＜0.05).Compared with group A,the ED in groups B and C were reduced by 82.86％and 93.90％respectively,and the ED in group C was reduced by 64.44％compared with group B.Conclusion Increasing the NI combined with the DLIR technique can significantly reduce the radi-ation dose during CT-guided PTNB.

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 analyze the efficacy and safety of FOLFOX-hepatic arterial infusion chemotherapy (HAIC) combined with targeted immunotherapy for initial unresectable hepatocellular carcinoma.Methods:A retrospective analysis was conducted on the data of initial unresectable hepatocellular carcinoma patients who visited Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from June 2022 to June 2023. A total of 51 patients were enrolled, including 47 males and 4 females, with the age of (56.1±10.7) years. All 51 patients received HAIC combined with immune targeted therapy. After each HAIC combined with immune targeted therapy, the efficacy was evaluated according to the modified response evaluation cirteria in solid tumor (mRECIST). Objective response rate and disease control rate were calculuted. The conversion surgery rate and adverse events during treatment were recorded. Follow up patients' disease progression and survival status, and meanwhile analyze prognosis.Results:According to mRECIST assessment, the number of patients with complete remission, partial remission, disease stability, and disease progression were 4 (7.8%), 27 (52.9%), 14 (27.4%), and 6 (11.8%), respectively. The disease remission rate was 60.8%(31/51), and the disease control rate was 88.2%(45/51). After HAIC combined with immune targeted therapy, 13 patients underwent liver cancer resection, with a surgical conversion rate of 25.5%(13/51). The median progression free survival of 51 patients was 14.2 months, and the median overall survival has not yet been reached. The progression free survival rates of 51 patients at 6 and 12 months were 90.2% and 64.7%, respectively, and the cumulative survival rates at 6 and 12 months were 100% and 86.3%, respectively. During the treatment period, all patients experienced various degrees of adverse reactions, 38(75.5%) patients were grade 1-2 adverse accidents, which could be relieved and controlled after corresponding treatment.Conclusion:FOLFOX-HAIC combined with targeted immunotherapy provides an effective and safe treatment option for unresectable hepatocellular carcinoma, offering surgical resection opportunities for unresectable hepatocellular carcinoma patients.

Infectious diseases are a great threat to human health.Rapid and accurate detection of pathogens is important in the diagnosis and treatment of infectious diseases.Metagenomics next-generation sequencing(mNGS)is an unbiased and comprehensive approach for detecting all RNA and DNA in a sample.With the development of sequencing and bioinformatics technologies,mNGS is moving from research to clinical application,which opens a new avenue for pathogen detection.Numerous studies have revealed good potential for the clinical application of mNGS in infectious diseases,especially in difficult-to-detect,rare,and novel pathogens.However,there are several hurdles in the clinical application of mNGS,such as:(1)lack of universal workflow validation and quality assurance;(2)insensitivity to high-host background and low-biomass samples;and(3)lack of standardized instructions for mass data analysis and report interpretation.Therefore,a complete understanding of this new technology will help promote the clinical application of mNGS to infectious diseases.This review briefly introduces the history of next-generation sequencing,mainstream sequencing platforms,and mNGS workflow,and discusses the clinical applications of mNGS to infectious diseases and its advantages and disadvantages.
