T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

Objective To explore the mechanism of Baihu Decoction in the treatment of acute lung injury based on network pharmacology and molecular docking technology;To carry out experimental verification.Methods The active components and targets of Baihu Decoction were searched through TCMSP and BATMAN-TCM databases,and human gene searches were conducted in GeneCards,NCBI,and OMIM databases.PPI network construction and GO and KEGG pathway enrichment analysis were conducted to determine the important signaling pathways of Baihu Decoction and acute lung injury.Molecular docking of main active components and core target proteins was performed.The effects of Baihu Decoction on survival rate and inflammatory cytokine content in acute lung injury lethal model mice were observed through animal experiments.Results Totally 211 common targets for Baihu Decoction and acute lung injury were screened,and identified effective components such as quercetin,kaempferol,and stigmasterol,etc.Analysis of KEGG pathway enrichment indicated that Baihu Decoction exerted its pharmacological effects in acute lung injury through a variety of signal pathways,including Toll-like receptor signaling pathway,NOD-like receptor signaling pathway,T cell receptor signaling pathway,and MAPK signaling pathway.Molecular docking results showed that Baihu Decoction had good binding strength with MAPK14,STAT3,JUN,MAPK1,MAPK3,FOS and RELA.The results of animal experiments showed that compared with the model group,the survival rate of mice in the Baihu Decoction group was significantly increased,the degree of pathological injury in the lung tissue was reduced,and serum IL-6,TNF-α contents decreased significantly(P<0.05).Conclusion Baihu Decoction can treat acute lung injury by reducing pathological injury to lung tissue and releasing of inflammatory factors.

Background: Millions of patients undergo cardiac surgery each year. The red blood cell distribution width (RDW) could help predict the prognosis of patients who undergo percutaneous coronary intervention or coronary artery bypass surgery. We investigated whether the RDW has robust predictive value for the 30-day mortality among patients in an intensive care unit (ICU) after undergoing cardiac surgery. Methods: Using the Medical Information Mart for Intensive Care-IV Database, we retrieved data for 11,634 patients who underwent cardiac surgery in an ICU. We performed multivariate Cox regression analysis to model the association between the RDW and 30-day mortality and plotted Kaplan–Meier curves. Subgroup analyses were stratified using relevant covariates. Receiver operating characteristic (ROC) curves were used to determine the predictive value of the RDWs. Results: The total 30-day mortality rate was 4.2% (485/11,502). The elevated-RDW group had a higher 30-day mortality rate than the normal-RDW group (P < 0.001). The robustness of our data analysis was confirmed by performing subgroup analyses. Each unit increase in the RDW was associated with a 17% increase in 30-day mortality when the RDW was used as a continuous variable (adjusted hazard ratio = 1.17, 95% confidence interval, 1.10–1.25). Our ROC results showed the predictive value of the RDW. Conclusions An elevated RDW was associated with a higher 30-day mortality in patients after undergoing cardiac surgery in an ICU setting. The RDW can serve as an efficient and accessible method for predicting the mortality of patients in ICUs following cardiac surgery.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

Cryoablation therapy with explicit anti-tumor mechanisms and histopathological manifestations has a long history.A large number of clinical practice has shown that cryoablation therapy is safe and effective,making it an ideal tumor treatment method in theory.Previously,its efficacy and clinical application were constrained by the limitations of refrigerants and refrigeration equipment.With the development of the new generation of cryoablation equipment represented by argon helium knives,significant progress has been made in refrigeration efficien-cy,ablation range,and precise temperature measurement,greatly promoting the progression of tumor cryoablation technology.This consensus systematically summarizes the mechanism of cryoablation technology,indications for oral mucosal melanoma(OMM)cryotherapy,clinical treatment process,adverse reactions and management,cryotherapy combination therapy,etc.,aiming to provide reference for carrying out the standardized cryoablation therapy of OMM.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Objective:To retrospectively construct competency-based portfolios for medical students to analyze the factors influencing competency self-assessment, and to explore an approach to efficient portfolio construction.Methods:The participants were randomly selected among medical graduates of 2015 in Shantou University Medical College. Through records collection and an online questionnaire survey, portfolios were built for the participants based on their development data during eight years from college entrance, college education, to post-graduation medical education. The correlation between variables was determined using Kendall's tau-b correlation coefficients. The inter-group differences were analyzed using the Mann-Whitney U test. Results:A total of 126 usable questionnaires for effective developmental portfolios were collected. There were a total of 208 indicators collected, including 79 questionnaire indicators (including 36 for competency self-assessment). The reliability coefficient (Cronbach's α) of the questionnaire was 0.984. The factors related to competency self-assessment were identified. Conclusion:This study provides a basis for the implementation of portfolio assessment, which can promote students' self-assessment and competency development. Optimizing the indicator system, building an online platform, increasing participants' participation motivation, and emphasizing self-reflection and feedback will help improve the efficiency of developmental portfolio construction and its performance.
