Objective:To investigate the efficacy and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for the treatment of BCR::ABL-negative chronic neutrophilic leukemia (CNL) and MDS/MPN with neutrophilia.Methods:This study retrospectively analyzed 12 cases of CNL and MDS/MPN with neutrophilia that underwent allo-HSCT from March 2017 to June 2024, comprising 7 males and 5 females with a median age of 48 ( IQR: 28, 59) years. The 2-year overall survival (OS), disease-free survival (DFS), cumulative incidence of relapse (CIR), and transplantation-related mortality (TRM) rates were analyzed. Complications were also assessed. Results:Of the 12 patients, 6 received matched sibling HSCT and 6 received haploidentical HSCT. All patients had successful engraftment, and the median times of neutrophil and platelet engraftment were 17 ( IQR: 11, 24) days and 15 ( IQR: 9, 28) days, respectively. Grade Ⅱ–Ⅳ acute graft versus host disease (GVHD) and chronic GVHD occurred in 2 and 4 cases, respectively. The 2-year OS, DFS, CIR, and TRM rates were (65.6 ± 16.4) %, (41.7 ± 16.6) %, (47.2 ±18.2) %, and (11.1 ± 11.4) %, respectively, after a median follow-up time of 637 ( IQR: 330, 943) days. One patient died from treatment-related complications due to respiratory failure caused by coronavirus disease 2019. Two patients died due to relapse. Conclusion:Allo-HSCT can be applied as a safe and effective approach to treat CNL and MDS/MPN with neutrophilia.

Objective:To investigate the efficacy of venetoclax combined with hypomethylating agents (Ven-HMA), in patients with core binding factor acute myeloid leukemia (CBF-AML) intolerant to intensive induction therapy.Methods:This study retrospectively analyzed patients newly diagnosed with CBF-AML who were aged <60 years and who received Ven-HMA as induction therapy at the Department of Hematology, the First Affiliated Hospital of Soochow University, between January 2020 and June 2023. Baseline characteristics and treatment responses of the patients were collected.Results:A total of 70 treatment-na?ve patients receiving Ven-HMA induction therapy were enrolled, of which 38 were men and 32 women [median age: 43 (34 - 55) years]. Of the 70 patients, 44 (62.9%) achieved complete remission (CR) /CR with incomplete hematologic recovery (CRi), 16 (22.9%) achieved partial remission, and 10 (14.2%) exhibited no response after one induction cycle. Among the 32 t (8;21) -positive patients with AML, only 8 (25.0%) achieved CR/CRi, of whom 3 (37.5%) remained measurable residual disease (MRD) -positive; among the 38 inv (16) -positive patients, 36 (94.7%) achieved CR/Cri, of whom 12 (33.3%) remained MRD-positive. Patients harboring the CBFβ::MYH11 fusion gene showed significantly higher response rates to Ven-HMA induction than those with the RUNX1:: RUNX1T1 fusion gene ( P<0.01) . Conclusion:Ven-HMA represents a novel therapeutic strategy that exhibits significant efficacy in inv (16) -positive patients; however, it demonstrates relatively lower remission rates in t (8; 21) -positive patients.

Objective To evaluate the effect of optical body surface monitoring system(OSMS)in setup of intensity modulated radiotherapy(IMRT)for thoracic tumorsand to analyze its relationship with BMI.Methods Thesetup errors of CBCT and location CT with body membrane and the registration errors of OSMS and first body surface reference image without body membrane were obtained in 49 patients with thoracic tumor who received routine intensity modulated radiotherapy.The paired t-test was used to analyze the difference of registration errors between the two image guidance methods.Pearson′s correlation analysis was used to analyze the correlation between CBCT errors and OSMS errors,and Bland-Altman analysis was employed to evaluatethe agreement of the two errors.The correlation and consistency of the two registration errors in patients with different BMI index were analyzed.PTV external marginsby the two registration methods were calculated using Van Herk formula.Results The OSMS and CBCT groups demonstrated significant differences in setup errors in the ventrodorsal direction(P<0.05),while no significant differences were found in the left-right,head-foot translation directions,or RTN rota-tion directions(P>0.05).Although the two methods showed a significant correlation in setup errors(P<0.05),this correlation was only moderate in the head-foot and left-right directions(r=0.500,0.408),weak in the RTN rotation direction(r=0.339),and very weak in the ventrodorsal direction(r=0.152).The limits of agreement(LOA,95％CI)between the two methods were[-0.45,0.45]cm in the left-right direction,[-0.59,0.57]cm in the head-foot direction,and[-0.48,0.40]cm in the ventrodorsal direction,with(-2.08°～2.19°)in the RTN rotation direction.Different BMI levels influenced the results of the two registration methods,particularly in patients with a BMI of 18.5～23.9 kg/m2.In this group,OSMS and CBCT exhibited a strong correlation in the head-foot direction(r=0.731),a moderate correlation in the left-right direction(r=0.512),and weak correlations in the ventrodorsal and RTN rotation directions(r=0.345,0.267).The absolute difference in setup errors between the two imaging systems was 0.4～0.5 cm/2°.Using CBCT and OSMS image guidance,the margins in the left-right,head-foot,and ventrodorsal directions were[0.5 cm,0.7 cm,0.3 cm]for CBCT,and[0.5 cm,0.7 cm,0.5 cm]for OSMS.Conclusion In chest tumor patients with a BMI of 18.5～23.9 kg/m2,OSMS and CBCT image guidance methods show good correlation in the head-foot and left-right directions,but their limits of agreement exceed the clinically acceptable range.OSMS cannot yet replace CBCT for image guidance in chest tumor intensity-modulated radiotherapy.Further improvements to tumor motion surrogates are necessary to enhance the accuracy of OSMS image guidance.

Background Job burnout has become an important factor affecting the mental and physical health and work efficiency of college counselors, and indirectly affects the quality and development of talent cultivation for college students. Objective To explore the relationship between job stress, job crafting, and job burnout among college counselors, and to test the mediating role of job crafting between job stress and job burnout, in order to take targeted measures to alleviate job stress and job burnout of college counselors, reduce associated health risks, and improve the effectiveness of higher education. Methods An anonymous questionnaire survey was conducted among 400 counselors from social network communication groups by convenience sampling. The Counselor Work Stress Scale, Job Crafting Scale, and Maslach Burnout Inventory-General Survey were used. Harman's single-factor method was used to evaluate common method bias in the survey data. One-way ANOVA was applied to test the difference in job stress, job crafting, and job burnout among college counselors by demographic characteristics, and chi-square test was used to analyze the difference in reporting job burnout. Partial correlation analysis was used to evaluate the correlation between selected variables. Structural equation modeling was used to analyze the relationship of job stress, job crafting, and job burnout among college counselors, and Bootstrap analysis was used to test if there was a mediating effect of job crafting on the relationship between job stress and job burnout. Results Of the 390 questionnaires recovered, there were 338 valid questionnaires (86.67%). Among the included subjects, the mean scores of job stress, job crafting, and job burnout were (2.70±0.62), (3.77±0.62), and (2.09±1.09), respectively. The positive rate of job burnout was 76.9% (260/338), with a positive rate of 72.8% in exhaustion dimension and 59.8% in cynicism dimension. There were significant differences in job crafting scores among the college counselors by different genders and professional titles (P<0.05). Female counselors had significantly higher job burnout scores and positive rates than male counselors (P<0.05). The partial correlation analysis showed that job stress, work load, school evaluation and expectation, and interpersonal relationship were positively correlated with job burnout (r=0.562, 0.442, 0.473, and 0.455, respectively, P<0.01), and negatively correlated with job crafting (r=−0.271, −0.169, −0.246, and −0.247, respectively, P<0.01); job crafting, cognitive crafting, relationship crafting, and task crafting were negatively correlated with job burnout (r=−0.447, −0.452, −0.366, and −0.340, respectively, P<0.01). The modified structural equation modeling indicated that job stress negatively affected job crafting (b=−0.348, P<0.001) and positively affected job burnout (b=0.454, P<0.001); job crafting negatively affected job burnout (b=−0.459, P<0.001), and played a partial mediating role in the relationship between job stress and job burnout, and the effect value was 0.160 (95%CI: 0.102, 0.230) that accounted for 26.10% of the total effect. Conclusion Job burnout among the college counselors is prominent. Job crafting presents an inhibitory effect on job burnout. Job stress indirectly affects the occurrence of job burnout by inhibiting the generation of job crafting.

Objective:To investigate interleukin-37 (IL-37) expression in patients with diabetic kidney disease (DKD), and to assess the regulation of exogenous IL-37 on CD8 + T cell function in DKD patients. Methods:A cross-section study was carried out. Twenty healthy controls, thirty-six patients with diabetes mellitus type 2 (T2DM), and forty-seven DKD patients were enrolled in the study. Peripheral blood was collected. Plasma and peripheral blood mononuclear cells were isolated. IL-37 and soluble IL-1 receptor 8 (IL-1R8) levels in the plasma were measured by enzyme-linked immunosorbent assay (ELISA). IL-18 receptor α chain (IL-18Rα), IL-1R8 and immune checkpoint molecules levels in CD8 + T cells were measured by flow cytometry. CD8 + T cells were purified, and were stimulated with recombinant IL-37. CD8 + T cells were co-cultured with HEK293 cells in either direct contact or indirect contact manner. Levels of perforin, granzyme B, interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) were measured by ELISA. The proportion of target cell death was assessed by measuring lactate dehydrogenase level. Results:Plasma IL-37 levels in DKD patients [(63.42±23.30) ng/L] were significant lower than those in healthy controls [(143.02±50.67) ng/L] and T2DM patients [(87.88±40.62) ng/L] ( t=8.848, P<0.001; t=3.456, P<0.001). Plasma IL-37 level had good predictive values for T2DM in health individuals and for DKD in T2DM patients [the area under the curve was 0.797 (95% CI 0.676-0.917, P<0.001) and 0.691 (95% CI 0.576-0.807, P=0.003), respectively]. Plasma IL-37 level was negatively correlated with urea nitrogen ( r=-0.313, P=0.032) and creatinine ( r=-0.477, P<0.001), and positively correlated with estimated glomerular filtration rate (eGFR) ( r s=0.478, P<0.001) in DKD patients. IL-1R8 + CD8 + cell proportion in DKD patients (33.60%±9.47%) was significantly higher compared to healthy controls (16.29%±5.97%) and T2DM patients (17.13%±4.85%) ( t=7.545, 9.516, both P<0.001), but did not correlate with fast blood glucose, urea nitrogen, creatinine, or eGFR (all P>0.05). There were no statistical differences of IL-18Rα + CD8 + cell proportion, soluble IL-1R8 level, or immune checkpoint molecule proportion in CD8 + T cells among healthy controls, T2DM patients, and DKD patients (all P>0.05). Perforin and granzyme B secretions by CD8 + T cells were significantly elevated in DKD patients compared with healthy controls [(108.78±12.42) ng/L vs. (94.60±10.07) ng/L, t=3.096, P=0.005; (261.34±48.79) ng/L vs. (166.28±30.80) ng/L, t=3.387, P=0.002] and T2DM patients [(108.78±12.42) ng/L vs. (92.58±14.71) ng/L, t=3.263, P=0.003; (261.34±48.79) ng/L vs. (170.66±39.24) ng/L, t=2.627, P=0.014]. There were no significant differences of either IFN-γ or TNF-α secretions by CD8 + T cells among healthy controls, T2DM patients, and DKD patients (all P>0.05). In direct contact co-culture manner, CD8 + T cell-induced HEK293 cell death was down- regulated (13.03%±4.97% vs. 17.88%±5.19%, t=2.235, P=0.037). The levels of perforin [(222.02±25.79) ng/L vs. (294.30±25.58) ng/L, t=6.603, P<0.001], granzyme B [(416.27±90.24) ng/L vs. (524.71±115.53) ng/L, t=2.454, P=0.023], IFN-γ [(23.66±4.20) ng/L vs. (35.18±8.51) ng/L, t=4.026, P<0.001] and TNF-α [(1.62±0.29) μg/L vs. (2.09±0.57) μg/L, t=2.302, P=0.034] were also reduced as well. In indirect contact co-culture manner, there were no significant differences of CD8 + T cell-induced HEK293 cell death, perforin, or granzyme B levels between no stimulation and IL-37 stimulation (all P>0.05). IFN-γ and TNF-α levels in the supernatants were reduced in response to IL-37 stimulation [(23.56±6.24) ng/L vs. (32.56±9.90) ng/L, t=2.550, P=0.019; (1.41±0.31) μg/L vs. (2.10±0.44) μg/L, t=4.011, P<0.001]. Conclusion:IL-37 level is reduced in DKD patients.Exogenous IL-37 suppresses the cytotoxicity of CD8 + T cells in DKD patients.

Most of the current research on depression focuses on neuronal regulation,while the astrocytic mechanism of depression is far from explored.Astrocytes are the most numerous and widely distributed glial cells in the central nervous system.With a complex structural morphology,astrocytes play an important role in a variety of neuropsychiatric disorders by interacting with neuronal synapses,vasculature and other glial cells.Recent studies have shown that astrocytes may be involved in depression by regulating monoamine transmitters,glutamate cycle,synaptic plasticity,energy metabo-lism,and neuroinflammation.This review is intended to inspire new ideas for the treatment of depres-sion and the development of novel drugs based on astrocyte regulation.

Objective To identify the characteristics and research status of symptom clusters in patients with lung cancer patients during chemotherapy.Methods This scoping review was conducted under the Joanna Briggs Institute guidelines.A literature search was performed in the PubMed,Embase,CINAHL,Web of Science,Scopus,CNKI,Wanfang,and CBM databases to identify relevant studies about symptom clusters in patients with lung cancer from inception until December 31,2023.The included studies were summarized and analyzed.Results 19 papers were included and 22 symptom clusters were extracted,mainly including psychological,gastrointestinal,lung cancer-specific,fatigue-related,and respiratory symptom clusters.There are 6 symptom cluster assessment tools,of which 4 were M.D Anderson Symptom Inventory in different version;the symptom clusters were dynamically changing during chemotherapy in patients with lung cancer,with variations in core symptom clusters at different stages.Conclusion Multiple symptom clusters exist during chemotherapy in lung cancer patients,and the naming of symptom clusters and attribution of symptoms need to be further standardized.The assessment tools for symptom clusters in patients undergoing chemotherapy for lung cancer are mainly based on the Anderson Symptom Assessment Scale and other language versions.Symptom clusters in patients with lung cancer during chemotherapy show dynamic changes,and there are differences in core symptom groups at different stages.
