    Abstract Chimeric antigen receptor (CAR)-T-cell therapy has greatly improved outcomes for patients with relapsed or refractory hematological malignancies. However, challenges such as treatment resistance, relapse, and severe toxicity still hinder its widespread clinical application. Traditional transcriptome analysis has provided limited insights into the complex transcriptional landscape of both leukemia cells and engineered CAR-T-cells, as well as their interactions within the tumor microenvironment. However, with the advent of single-cell sequencing techniques, a paradigm shift has occurred, providing robust tools to unravel the complexities of these factors. These techniques enable an unbiased analysis of cellular heterogeneity and molecular patterns. These insights are invaluable for precise receptor design, guiding gene-based T-cell modification, and optimizing manufacturing conditions. Consequently, this review utilizes modern single-cell sequencing techniques to clarify the transcriptional intricacies of leukemia cells and CAR-Ts. The aim of this manuscript is to discuss the potential mechanisms that contribute to the clinical failures of CAR-T immunotherapy. We examine the biological characteristics of CAR-Ts, the mechanisms that govern clinical responses, and the intricacies of adverse events. By exploring these aspects, we hope to gain a deeper understanding of CAR-T therapy, which will ultimately lead to improved clinical outcomes and broader therapeutic applications.

    Abstract Acute lymphoblastic leukaemia (ALL) is the most prevalent cancer in children, and excessive iron buildup resulting from blood transfusions and chemotherapy potentially has a negative impact on treatment outcomes and prognosis in patients with ALL. Therefore, initiating early iron chelation therapy during ALL treatment is a logical approach. Ideally, the selected iron chelator should also possess anti-leukaemia properties. The aim of the present study was to explore the potential impact and underlying mechanism of deferasirox (DFX) in ALL therapy. This study proved that DFX, an iron chelator, is capable of inducing leukaemia cell death through ferroptosis, which is achievable by increasing the expression of acetylated nuclear factor erythroid 2-related factor 2 (NRF2). More specifically, NRF2 acetylation on Lys599 was facilitated by acetyltransferase-p300/CBP. These findings indicate that DFX could serve as a potent adjunctive medication for patients with ALL. Moreover, DFX may offer dual benefits in ALL treatment, functioning as both an iron chelator and NRF2-modulating agent. Further research and clinical trials are necessary to fully elucidate the therapeutic potential of DFX in patients with ALL and incorporate it into treatment protocols.

    Abstract Purpose: To examine the trajectory of decisional conflict and anxiety experienced by adolescents after the cancer diagnosis, and explore their perceptions on participation in shared decision-making (SDM).
    Design: This longitudinal study used incorporated data from questionnaires and interviews.
    Methods: Participants recruited from an academic hospital in southern Taiwan ranged in age from 13 to 20 years with a cancer diagnosis within 1 month and received cancer treatment. Each participant completed questionnaires on decisional conflict and anxiety at diagnosis, 1, 3, and 6 months later. Individual interviews were to gain an in-depth understanding of SDM.
    Findings: Total scores on decisional conflict changed significantly over time (F = 2.98, p = 0.039); the scores at 1 month were higher than 3 months (t = 2.18, p = 0.04) and 6 months (t = 2.97, p = 0.008). Participants perceived significantly different levels of values clarify (F = 9.49, p < 0.01) and support (F = 8.46, p < 0.01) over time. Only 27.3% of participants were anxiety-free. No significant differences were found in anxiety over time. The perception of SDM was a situational involvement.
    Conclusions: Decisional conflict changed over time. Participants experienced greater decisional conflict at 4-8 weeks after diagnosis and their anxiety did not decrease over time. The different levels of participation in SDM during their treatment trajectory were found.
    Clinical relevance: Participants experienced the highest decisional conflict during diagnosis, and highlighted how their roles in healthcare discussions varied from direct participation to indirect involvement. Further research is needed to develop an SDM model which accommodates different levels of needs and implements timely support.

    Abstract Cytarabine is an important medicine for acute myeloid leukemia (AML) treatment, however, drug resistance hinders the treatment of AML. Although microRNA (miRNA or miR) alteration is one of the well-recognized mechanisms underlying drug resistance in AML, few studies have investigated the role and function of miRNAs in the development of cytarabine resistance. In the present study, total RNA was isolated from parental HL60 and cytarabine-resistant HL60 (R-HL60) cells. Subsequently, miRNAs and mRNAs were detected using small RNA sequencing and gene expression array, respectively. Differentially expressed mRNAs (DEMs) and differentially expressed genes (DEGs) with more than two-fold changes between HL60 and R-HL60 cells were screened out. Negatively associated miRNA-mRNA pairs were selected as candidate miRNA-mRNA target pairs according to the miRDB, Targetscan or miRTar databases. Functional enrichment analysis of DEGs included in the candidate miRNA-mRNA pairs was performed. The results indicated that 10 DEGs (

    Abstract Removing As(Ⅲ)from water steadily and efficiently is still a challenging global issue. In this study, novel FeMnNi-LDHs were prepared by a co-precipitation method using Fe, Mn, and Ni as lamellar cations, and the structure were characterized by XRD, TEM, FT-IR, and XPS techniques, and the adsorption performance and mechanism of As(Ⅲ)was explored. The results showed that FeMnNi-LDHs have typical characteristic peaks of layered double hydroxides, with sharp peaks and high crystallinity. The TEM images also show obvious layered structures. The adsorption kinetics of As(Ⅲ)on FeMnNi-LDHs agree with the quasi second-order kinetic model, and the isotherm adsorption curve agrees with the Freundlich isotherm equation. The maximum adsorption capacity at 45℃ was 240.86 mg·g

    Abstract Objective: This study aims to discuss the differential diagnosis value of endometrial volume and flow parameters in combination with serum carbohydrate antigen 125 (CA125) in endometrial benign and malignant lesions.
    Materials and methods: The data of 250 patients with endometrial lesions were retrospectively analyzed. Carbohydrate antigen 125 (CA125) was determined before the operation. The morphology, hemodynamics, volume and flow parameters of the endometrium were measured by transvaginal three-dimensional-power Doppler angiography (3D-PDA). The endometrial volume (EV), 3D-PDA vascular index (VI), flow index (FI) and vascularization flow index (VFI) were calculated using the virtual organ computer-aided analysis software (VOCAL).
    Results: According to the pathological results, 202 patients (80.8%) had benign endometrial lesions and 48 patients (19.2%) had endometrial cancer (EC). The endometrium of EC patients was thicker (15.64 ± 7.26 mm vs. 9.24 ± 5.06 mm, P < 0.001), the endometrial volume was larger (9.23 ± 4.08 ml vs. 2.26 ± 3.42 ml, P < 0.001), and the flow parameters VI, FI and VFI were higher, when compared to those of benign lesions (P < 0.001). The area under the receiver operating characteristic curve (AUROCC) of VI receptors was 0.86, while the AUC of endometrial thickness (ET) was only 0.66. Therefore, the best variable for distinguishing benign and malignant endometrial lesions was VI. The level of CA125 in the EC group significantly increased (40.57 ± 17.45 vs. 17.87 ± 7.64, P < 0.001), and the level of CA125 increased (P < 0.05) with the increase in clinical grade, degree of tumor differentiation, and pelvic lymph node metastasis (P < 0.05). However, the difference in myometrial invasion was not statistically significant (P > 0.05).
    Conclusion: Transvaginal 3D-PDA can clearly show the morphological and hemodynamic characteristics of endometrial lesions, and assist in the detection of EC in combination with serum CA125. This may have important clinical application value.

    Abstract Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. While ALL therapies are highly effective, western studies have shown excesses late life effects of therapies in survivors. In this survey, we recruited subjects being diagnosed as ALL before the age of 18-year-old and had been in complete continuous remission for at least 3 years. Subjects were arranged to receive three cognitive tests (Wechsler intelligence test, Conners' continuous performance test, and Wisconsin card sorting test). Standardized questionnaires were used to inquiry about attention problem in real life context. Treatment outcome were compared between the standard risk and high/very high risk groups. Final survivors were 42 subjects (26 males, 16 females) with median current age of 17.8 years. Subjects were diagnosed to be with ALL at a median age of 4.8 years. The median survival time (from discontinuation of ALL treatment to the study date) was 8.4 years. Results indicated that 17 subjects (40.5%) had chronic physical conditions in need of clinical management and six subjects (14.3%) had mental condition. For the performance-based cognitive outcome, the average full scale intelligence quotient was 91.7 ± 13.8. Ten percent of the subjects had problem in test of attention, 20% had problem in test of impulsivity and 42.8% of the subject had problems in executive function. When judged from real life contexts, 19 subjects (42%) were with obvious attention problems. Group comparison between standard risk vs high/very high risk patients revealed no difference in neurocognitive outcomes. We hope that this information may benefit the implementation of follow-up program for Taiwanese pediatric leukemia survivors.

    Abstract Background and objectives: In response to the COVID-19 pandemic outbreak and to ensure the safety of epidemic prevention in the hospital, the hospital has established mitigation strategies in advance including risk assessment and effect analysis to control hospital visitors and accompanying persons. The study aims to assess the effectiveness of mitigation strategies implemented to effectively prevent the invasion and spread of the virus.
    Method: Conduct a status analysis in accordance with the Healthcare Failure Mode and Effect Analysis (HFMEA) 4-step model, construct a response workflow, confirm the failure mode and potential causes, perform hazard matrix analysis and decision tree analysis, and formulate risk control management measures.
    Results: For the 4 main processes and 9 subprocesses of the accompanying carers and contract caregivers entering the hospital, 26 potential failure modes and 42 potential causes of failure were analyzed. Following implementing improvement measures including strategies targeting the accompanying person, mitigation workflow failure rates decreased from 42 to 13 items, the pass rate for the maximum body temperature cutoff increased from 53.1% to 90.8%, and the compliance rate of hand washing increased from 89.5% to 100%.
    Conclusion: The HFMEA model can effectively implement preventive risk assessment and workflow management of high-risk medical procedures. The model can adjudicate the health of hospital visitors during the epidemic/pandemic, provide epidemic/pandemic education training and preventive measure health education guidance for hospital visits, and improve their epidemic prevention cognition. When combined, these strategies can prevent nosocomial infection to achieve the best anti-epidemic effect.

    Abstract Immune tumor microenvironment (TME) in neuroblastoma (NBL) contributes to tumor behavior and treatment response. T cells and natural killer (NK) cells have been shown to play important roles in the neuroblastoma TME. However, few reports address the clinical relevance of natural killer T cells (NKTs) and interleukin-15 (IL-15), one of the crucial cytokines controlling the activation and expansion of NK/NKT cells, in NBL. In this study, we examined NKT immunoscores and IL-15 expression in both MYCN-amplified and MYCN-non-amplified NBL to correlate with clinical outcomes such as event-free survival (EFS) and overall survival (OS).
