With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

Objective:To investigate the predictive value of endothelial activation and stress index(EASIX)for the prognosis of patients with mantle cell lymphoma(MCL).Methods:A retrospective analysis was conducted to assess prognosis and compare the clinical features of patients diagnosed with MCL who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2010 to June 2023,had therapeutic indications and received standard treatment.Results:A total of 66 patients were included and divided into high EASIX group and low EASIX group,according to a cutoff value of 0.97 determined by the receiver operating characteristic(ROC)curve.Multivariate Cox regression analysis showed that prealbumin＜0.2 g/L,high EASIX,and ECOG PS score ≥2 were independent risk factors influencing overall survival(OS)in MCL patients.The median OS of patients in the high and low EASIX group was 13.0 and 37.5 months,and the median progression-free survival was 8.8 and 26.0 months,respectively.The proportions of patients with ECOG PS score ≥2 and prealbumin＜0.2 g/L at onset significantly increased in the high EASIX group compared to those in the low EASIX group.Conclusion:At the time of initial diagnosis,EASIX can serve as an independent prognostic indicator impacting OS in patients with MCL.Furthermore,patients in the high EASIX group experience a poorer prognosis and shorter survival duration compared with those in the low EASIX group.

Objective To explore the clinical efficacy of Shenggu Tablets(mainly composed of Pyritum,Sappan Lignum,Dalbergiae Odoriferae Lignum,Notoginseng Radix et Rhizoma,Anemarrhenae Rhizoma,Rehmanniae Radix,Pheretima,and Os Draconis)combined with extension osteotomy using Taylor spatial frame(TSF)in the treatment of open tibial fracture with bone defect.Methods The clinical data of 73 patients with open tibia fracture and bone defect more than four centimeters admitted to Foshan Hospital of Traditional Chinese Medicine from July 2018 to September 2022 were retrospectively analyzed.The patients were divided into the observation group(37 cases)and the control group(36 cases)according to the medication of Shenggu Tablets or not.The control group was treated with extension osteotomy using TSF,and the observation group was treated with Shenggu Tablets combined with extension osteotomy using TSF until the healing of fractures.Six months after the operation,the clinical effect,total effective rate assessed by imaging,fracture healing time,and the incidence of complications in the two groups were compared.Results(1)Six months after the operation,the distinguished rate of clinical efficacy and the total effective rate assessed by imaging in the observation group were all 100.00%(37/37),which were significantly higher than those in the control group[(83.33%(30/36),86.11%(31/36)respectively],and the intergroup comparison showed that the differences were statistically significant(P＜0.05).(2)The fracture healing time of the observation group was(11.47±0.77)months,which was significantly shorter than that of the control group[(14.42±1.40)months],and the difference was statistically significant(P＜0.01).(3)The total incidence of postoperative complications in the patients of the observation group was 13.51%(5/37),which was significantly lower than that in the control group[38.89%(14/36)],with a statistically significant difference(P＜0.05).Conclusion Shenggu Tablets combined with extension osteotomy using TSF exerts certain efficacy in the treatment of open tibial fracture with bone defect by significantly promoting fracture healing,improving bone transport and speeding up osteogenic mineralization,shortening the time of fracture healing,and reducing the time of wearing the TSF.

Most patients with differentiated thyroid cancer have a good prognosis after radioiodine-131 therapy,but a small number of patients are insensitive to radioiodine-131 therapy and even continue to develop disease.At present,some targeted drugs can improve progression-free survival in patients with radioactive iodine-refractory differentiated thyroid cancer(RAIR-DTC),such as sorafenib and levatinib,have been approved for the treatment of RAIR-DTC.However,due to the presence of primary and acquired drug resistance,drug efficacy in these patients is unsatisfactory.This review introduces the acquired drug resistance mechanism of sorafenib in the regulation of mitogen-activated protein kinase(MAPK)and phosphatidylinositol-3-kinase(PI3K)pathways and proposes related treatment strategies,in order to provide a reference for similar drug resistance mechanism of sorafenib and effective treatment of RAIR-DTC.

Spinal surgical site infection (SSI), especially deep SSI after internal fixation is difficult in treatment, with long course of disease and poor prognosis. At present, there are many controversies in the diagnosis and treatment of spinal SSI, with unsatisfactory overall efficacy of its diagnosis and treatment. Besides, no diagnosis and treatment guideline based on evidence-based medicine has been in existence. To this end, the Spinal Infection Group of the Orthopedic Branch of the Chinese Medical Doctor Association and the Spinal Infection Group of the Spinal Surgery Branch of the Chinese Rehabilitation Medicine Association jointly organized relevant experts to formulate Evidence-based clinical guideline for the diagnosis and treatment of surgical site infection in spinal trauma ( version 2024) based on an evidence-based approach. A total of 10 recommendations were proposed on the diagnosis and treatment of spinal SSI, so as to provide a clinical reference for the diagnosis and treatment of spinal SSI.

As artificial intelligence technology rapidly advances, its deployment within the medical sector presents substantial ethical challenges. Consequently, it becomes crucial to create a standardized, transparent, and secure framework for processing medical data. This includes setting the ethical boundaries for medical artificial intelligence and safeguarding both patient rights and data integrity. This consensus governs every facet of medical data handling through artificial intelligence, encompassing data gathering, processing, storage, transmission, utilization, and sharing. Its purpose is to ensure the management of medical data adheres to ethical standards and legal requirements, while safeguarding patient privacy and data security. Concurrently, the principles of compliance with the law, patient privacy respect, patient interest protection, and safety and reliability are underscored. Key issues such as informed consent, data usage, intellectual property protection, conflict of interest, and benefit sharing are examined in depth. The enactment of this expert consensus is intended to foster the profound integration and sustainable advancement of artificial intelligence within the medical domain, while simultaneously ensuring that artificial intelligence adheres strictly to the relevant ethical norms and legal frameworks during the processing of medical data.

This study investigated the role of protein kinase D(PKD)in the replication of human coronavirus 229E(HCoV-229E)and its potential molecular mechanisms.Using MRC-5 cells as a model,we assessed the expression levels of PKD family genes and proteins through qPCR and western blotting.We knocked down Prkd3 with siRNA and inhibited PKD activity with CRT0066101 to examine the replication lev-els of HCoV-229E-infected cells.Cell viability was assessed with CCK8,viral titration was determined with the TCID50,and immunofluorescence staining was used to assess HCoV-229E expression and the structure of the trans-Golgi network(TGN).The level of phosphatidylinositol 4,5-bisphosphate(PI(4,5)P2)was measured to reflect phosphatidylinositol 4-kinaseⅢβ(PI4KⅢβ)activity.PI4KⅢβ activity was inhibited with a PI4KⅢβ inhibitor(BQR695)to observe changes in TGN struc-ture and HCoV-229E replication after cell infection.CRT0066101 was used to inhibit PKD activity in Vero-E6 cells,and HCoV-229E replication levels were examined post-infection.The expression levels of PKD family genes and proteins,including Prkd1,Prkd2 and Prkd3,significantly increased during HCoV-229E infection.Knockdown of PKD3 significantly inhibited HCoV-229E mRNA levels and titers with respect to those in the control group(t=8.999,P＜0.001;t=6.920,P＜0.001),whereas overexpression of PKD3 increased HCoV-229E mRNA levels and titers(t=6.630,P＜0.001;t=5.794,P＜0.001).CRT0066101 also significantly inhibited HCoV-229E mRNA levels and titers(t=6.931,P＜0.001;t=4.055,P＜0.01).Im-munofluorescence staining indicated that CRT0066101 inhibited TGN fission caused by HCoV-229E infection.Inhibition of PI4KⅢβ activity significantly decreased PI(4,5)P2 levels,and BQR695 rescued the elevated PI(4,5)P2 levels caused by PKD overexpression(t=6.671,P＜0.01).BQR695 decreased TGN fission in HCoV-229E-infected cells,and HCoV-229E mRNA levels and titers(t=5.151,P＜0.001;t=7.744,P＜0.001).CRT0066101 inhibited HCoV-229E mRNA levels and titers in Vero-E6 cells(t=7.480,P＜0.001;t=7.228,P＜0.01).This study revealed that PKD regulates TGN fission through modu-latingPI4KⅢβ and is involved in HCoV-229E replication.PKD inhibitors and PI4KⅢβ inhibitors significantly decreased HCoV-229E replication,thus providing important insights for future research onthe treatment of coronavirus infections.

This study was aimed at understanding the genome-wide characterization and variations for three imported novel coronavirus(SARS-CoV-2)strains from different sources in the same period in Jinan at the viral genome level,to provide a sci-entific basis for further improving the prevention and control of COVID-19 outbreaks at Jinan port.We selected nasal and pha-ryngeal swab samples from three cases of imported asymptomatic COVID-19infectionat Jinan port;performed second-genera-tion whole-genome sequencing;and analyzed the variant loci and homology withvarious bioinformatics software.The whole ge-nome sequence of SARS-CoV-2 was successfully obtained from three samples of asymptomatic infected cases,and had full lengths ranging from 29 835 bp to 29 844 bp.Pangolin typing results indicated that the genotypes of the three samples were O-micron BQ.1,BQ.1.1,and BQ.1.12.Compared with the original Wuhan strain,the three samples produced mutations at 77,80,and 78 base sites,respectively,involving 60-63 non-synonymous mutations,mainly in the S and ORF1ab genes.Omicron BQ.1 is an imported variant of the SARS-CoV-2 virus and was detected for the first time at Jinan port.From a molecular biolo-gy perspective,this study provides a theoretical basis for the source tracing and prevention and control of COVID-19 at theport.
