Chronic myeloid leukemia (CML) is a malignant hematologic disorder caused by abnormal proliferation of hematopoietic stem cells. In recent years, while the application of tyrosine kinase inhibitors (TKIs) has significantly improved the prognosis of CML patients through in-depth exploration of pathogenesis of CML and advancements in targeted therapies, some patients still face challenges including drug resistance, disease relapse, and failure to achieve treatment-free remission. Imunotherapy, as a complementary or alternative strategy, holds significant potential for overcoming these limitations, and has gradually emerged as a critical research focus in CML treatment. This review aims to summarize the current research status and latest advances in immunotherapy for CML.

Objective: To develop a rapid quantification method for neutrophil extracellular traps (NETs) by quantifying neutrophils forming NETs (NETotic cells) on routine peripheral blood smears, and to evaluate the performance of an early warning model combining NETs with traditional coagulation indicators for risk of sepsis-induced coagulopathy (SIC) in septic patients. Methods: This prospective observational study was conducted in Wuxi People's Hospital Affiliated with Nanjing Medical University between May 2023 and May 2025. A total of 147 patients with sepsis (diagnosed based on Sepsis-3.0 criteria) who had not developed SIC [the international society on thrombosis and haemostasis (ISTH SIC score <4)] were enrolled. Blood samples were collected within 2 hours of admission. Neutrophil smudge cells (NETs%) were counted using an automated cell morphology analyzer. Serum levels of myeloperoxidase-DNA (MPO-DNA) complexes, circulating free DNA (cf-DNA) and sequential organ failure assessment (SOFA) scores were also determined. Based on progression to SIC (ISTH score ≥4) within 72 hours of admission, patients were categorized into a sepsis without SIC group (n=85) and a sepsis with SIC group (n=62). Risk factors were analyzed using binary logistic regression, receiver operating characteristic (ROC) curves were plotted, and the predictive value of NETs%, SOFA, and AT-Ⅲ for coagulation dysfunction was assessed. Results: The NETs% level was significantly higher in the sepsis with SIC group [8.50% (7.00, 11.50)] compared to both the healthy control group [1.00% (0.00, 2.00)] and sepsis without SIC group [4.40%(3.50, 6.50)] (P<0.01). NETs% was identified as an independent risk factor for SIC in sepsis patients. ROC analysis showed that the area under the curve (AUC) for predicting SIC was 0.90 for NETs%, 0.85 for MPO-DNA, and 0.79 for cf-DNA. The combined model of NETs% and SOFA score demonstrated the best performance, with an optimal cut-off value of 0.33, an AUC of 0.92, a sensitivity of 77%, and a specificity of 93%. Conclusion: NETs% shows promise as a novel biomarker for SIC. Peripheral blood smear morphology provides a simple, rapid, and cost-effective method for quantifying NETs%. NETs% enhances the early clinical identification of patients at high risk for SIC, and its combination with the SOFA score facilitates SIC prediction, offering a critical time window for initiating timely preventive interventions.

Objective To investigate the critical role of macrophage M1 polarization in mediating the effect of periodontitis on the progression of chronic obstructive pulmonary disease(COPD).Methods Alveolar lavage fluid samples were collected from COPD patients with comorbid periodontitis,and gene expression analysis was performed to validate the changes in the expression of M1 polarization-related genes.A mouse model of COPD,with experimentally induced periodontitis,were established.Hematoxylin and eosin(HE)staining of pathological sections was performed to observe the effect of periodontitis on COPD progression.Flow cytometry,immunofluorescence staining,and reverse transcription quantitative polymerase chain reaction(RT-qPCR)were performed to analyze the effect of periodontitis on macrophage M1 polarization and the expression of relevant genes in the alveolar lavage fluid and lung tissues.Results In clinical samples of alveolar lavage fluid from COPD patients with periodontitis,the expression of macrophage M1 polarization-related genes,including CD86,inducible nitric oxide synthase(iNOS),interleukin(IL)-1β,tumor necrosis factor(TNF)-α,IL-23,and IL-6,was upregulated compared with that of COPD patients without periodontitis.Analysis of a mouse disease model revealed that periodontitis affected the growth of COPD mice,with the final body mass of mice in the periodontitis and COPD comorbid group([21.3±0.52]g,day 34)lower than that of the COPD group([23.93±0.45]g,day 34).Pathological sections of the lung tissue showed that periodontitis exacerbated COPD progression,with more pronounced alveolar expansion and alveolar wall destruction observed in the periodontitis and COPD comorbid group.Flow cytometry revealed a higher proportion of M1-polarized macrophages in alveolar lavage fluid from COPD and periodontitis comorbid mice([31.36±2.51]%)compared with the COPD mice([23.19±1.07]%).Immunofluorescence assays indicated that periodontitis also promoted macrophage M1 polarization in the lung tissue of COPD mice.Gene expression analysis demonstrated that M1 polarization-related gene expression was significantly upregulated in both the alveolar lavage fluid and lung tissue of mice in the COPD and periodontitis co-morbid group compared to the COPD group.Conclusion Periodontitis exacerbates COPD progression by promoting macrophage M1 polarization in the lungs.Enhancing oral hygiene management and targeting the inhibition of macrophage M1 polarization may represent new therapeutic strategies for the clinical prevention and control of COPD.

TSCI have dyskinesia and sensory disturbance that can cause various life-threaten complications. The patients with traumatic spinal cord injury (TSCI), seriously affecting the quality of life of patients. Based on the epidemiology of TSCI and domestic and foreign literatures as well as expert investigations, this expert consensus reviews the definition, injury classification, rehabilitation assessment, rehabilitation strategies and rehabilitation measures of TSCI so as to provide early standardized rehabilitation treatment methods for TSCI.
