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 feasibility and effect of remote medical education model using online film reading training to improve the ability of ophthalmologists in the Xinjiang Uygur Autonomous Region (hereinafter referred to as "Xinjiang Region" ) in diagnosing fundus diseases.Methods:The three-level film reading training system of Xinjiang Production and Construction Corps system division hospital-Corps Hospital-Peking Union Medical College Hospital was established. From June 2022 to January 2023, 4 159 posterior color fundus images were continuously collected from Department of Ophthalmology of Xinjiang Corps Hospital and 4 divisional hospitals in the Corps medical system. Among them, hypertensive retinopathy, diabetic retinopathy, exudative age-related macular degeneration (AMD), atrophic AMD and retinal vein occlusion were 3 073, 651, 43, 186 and 206 cases, respectively. The images were divided into 3 rounds (first, second and last) according to the proportion of diseases. The doctors who participated in the training (hereinafter referred to as the "training") were 15 ophthalmologists from the Corps Hospital of Xinjiang Region and the division hospital of the Corps system. There were 7 male and 8 female. Age was (38.1±4.0) years. The titles of senior, deputy senior, intermediate and junior are 1, 6, 5 and 3 respectively; Bachelor's degree and master's degree are 13 and 2 respectively. The working time of fundus disease specialty was (9.6±3.3) years. The film reading system training was conducted before the first round of labeling, and after each round of film reading, the doctors of Peking Union Medical College Hospital gave feedback and explanation on the film reading results. The diagnostic consistency, sensitivity and specificity were compared by paired sample t test. Spearman or Pearson correlation analysis was conducted between the improvement of diagnostic level and professional title, education, age and working hours of ocular fundus disease. Results:All the participating doctors completed the first, second and last reading. After each round of film reading, the film reading summary was carried out for 2 hours. The average diagnostic agreement rates of participating physicians were 53.0%, 67.0% and 75.0%, respectively. The sensitivity and specificity were 0.38, 0.69, 054 and 0.66, 0.85, 0.96, respectively. There was significant difference between the first and last examination ( P<0.001). The sensitivity of the second reading was significantly higher than that of the first reading, and the sensitivity of the last reading was significantly lower than that of the second reading, with statistical significance ( P<0.05). The specificity of the second reading was significantly higher than that of the first reading, and the last reading was significantly higher than that of the second reading, with statistical significance ( P<0.05). There was no significant correlation ( P>0.05) between the improvement of diagnostic level of participating physicians and educational background ( Rho=0.07), professional title ( Rho=0.13), age ( r=0.20), and working time of ophthalmofundus disease specialty ( r=0.26). Conclusions:Relying on the three-level online telemedicine training, it can improve the ability of ophthalmologists in Xinjiang region to diagnose fundus diseases. The preliminary telemedicine education model has demonstrated potential for feasibility and effectiveness in remote areas with inadequate medical resources.

Objective To investigate the mechanism by which Colony Stimulating Factor-1(CSF1)inhibits apoptosis in neurons subjected to oxygen-glucose deprivation(OGD).Methods Primary rat cortical neurons were divided into the OGD damaged neuron model group(OGD group),the rh-CSF1 intervention group(rh-CSF1 group),and control group.The sample size for each group was 3.After intervention with recombinant human CSF1(rh-CSF1),neuronal apoptosis rate and intracellular ATP content,reactive oxygen species levels,mitochondrial membrane potential,and mitochondrial DNA copy number were measured.The content of malondialdehyde within mitochondria and the activity of superoxide dismutase were also assessed.Results Intervention with rh-CSF1 increased mitochondrial membrane potential(0.55±0.03 vs.0.43±0.06,P<0.01),mitochondrial DNA copy number(0.88±0.05 vs.0.72±0.06,P<0.05),ATP content[(15.70±0.99)mmol/mg vs.(11.70±1.00)mmol/mg,P<0.01)],and superoxide dismutase[(18.47±1.38)U/mg vs.(14.78±1.81)U/mg,P<0.05)]activity in neurons injured by OGD.It also reduced levels of rectivereactive oxygen species(3.64±0.21 vs.4.45±0.33,P<0.05)and malondialdehyde within mitochondria[(2.13±0.19)mmol/mg vs.(2.78±0.20)mmol/mg,P<0.05)],and inhibited neuronal apoptosis(10.12±0.78 vs.17.04±1.23,P<0.01)Conclusion rh-CSF1 may alleviate the damage in neurons induced by OGD by improving mitochondrial function,reducing oxidative stress,and inhibiting cell apoptosis.

Objective:To explore the scientificity of the public hospital liability policy governance from the perspective of policy tools,and to provide evidence for the optimization and adjustment of subsequent policies.Methods:Policy texts at the national and regional levels from 2009-2022 were selected,and the coding results were statistically analyzed using Excel 2019 based on Rothwell and Zegveld's classification of policy tools.Results:A total of 128 policy texts were included in the analysis,with 29.96%,34.16%,and 35.88%of the policy tools in the policy instrument dimension being demand-based,supply-based,and environment-based,respectively.The system mechanism dimension focused primarily on compensation mechanisms.Conclusion:The use of the three policy instruments is mainly dominated by environmental policies,with a relative lack of policies from demand side.It is recommended that the use of policies from demand side could be strengthened and the internal structure of policy tools be optimized,to improve the consistency and coupling of policies.
