Objective:To evaluate the safety and efficacy of mitoxantrone liposome (MIT-LIP) combined chemotherapy in treating mixed phenotype acute leukemia (MPAL) .Methods:December 2021 to November 2024, MPAL patients who underwent the MAED (MIT-LIP + cytarabine + etoposide + dexamethasone) regimen were retrospectively analyzed. Data on clinical characteristics, adverse reactions, therapeutic outcomes, and long-term prognoses were collected.Results:A total of 7 MPAL patients who received MAED regimen were admitted. Among them, two patients were initially diagnosed with T-ALL or B-ALL, respectively, and transformed into AML after treatment. Three patients were initially diagnosed as MPAL (B/myeloid), one as MPAL (T/myeloid), and one with MPAL (myeloid/plasmacytoid dendritic cell). Among the 7 patients, there were 3 males and 4 females, 1 chromosome abnormalities and 6 gene abnormalities, including 1 case with BCR∷ABL fusion gene. The median age was 38 years (range: 16–58 years). There was no clear related drug allergy and organ toxicity during MAED regimen, and the main adverse effect was hematological toxicity. After induced chemotherapy, all patients achieved complete remission (CR), 2 maintained MRD-negative CR and 1 maintained MRD-positive CR. The other 4 patients underwent allogeneic hematopoietic stem cell transplantation, 2 maintained MRD-negative CR, and 2 relapsed. The current median follow-up time was 12 months, the overall survival (OS) rate was 100%, the relapse-free survival (RFS) rate was 60%, and the median OS time and median RFS time were not reached.Conclusion:The MAED regimen demonstrates high safety and a favorable CR rate in MPAL treatment.

G protein-coupled receptors (GPCRs) are significant drug targets, but their potential in cancer therapy remains underexplored. Conventional GPCR agonists or antagonists have shown limited effectiveness in cancer treatment, necessitating new GPCR-targeting strategies for more effective therapies. This study discovers that Yersinia pestis LcrV, a crucial linker protein for plague infection, acts as a biased agonist of a GPCR, the formyl peptide receptor 1 (FPR1). The LcrV protein induces unique conformational changes in FPR1, resulting in G proteins being activated in a distinctive state without subunit dissociation. This leads to a biased signaling profile characterized by cyclic adenosine monophosphate (cAMP) responses and β-arrestin2 recruitment, but not calcium mobilization. In FPR1-expressing triple-negative breast cancer (TNBC) cells, LcrV bi-directionally modulates intracellular signaling pathways, downregulating extracellular signal-regulated kinases (ERK1/2) and Akt pathways while upregulating Jun N-terminal kinase (JNK) and p38 pathways. This dual modulation results in cell cycle arrest and the inhibition of TNBC cell proliferation. In TNBC xenograft mouse models, long-term LcrV treatment inhibits tumor growth more effectively than a conventional FPR1 antagonist. Additionally, LcrV treatment reprograms tumor cells by reducing stemness-associated proteins OCT4 and c-MYC. Our findings highlight the potential of biased GPCR agonists as a novel GPCR-targeting strategy for cancer treatment.

Objective: To investigate the association between the physical fitness index (PFI) and symptoms of depressive, anxiety and stress symptoms among college students, providing a reference for mental health interventions. Methods: From June to September 2025, combined convenience and cluster random sampling approach was used to administer questionnaire surveys and perform physical fitness tests on 2 712 college students from Zhejiang Chinese Medical University. The Depression Anxiety Stress Scales-21 Items (DASS-21) was used to assess mental health status. Chi square test and multivariate Logistic regression analysis were used to determine the associations between the PFI and the PFI component indicators with depressive, anxiety and stress symptoms. Results: The prevalence of depressive, anxiety and stress among college students were 24.26%, 33.22% and 13.68%, respectively. Statistically significant differences in the prevalence of these symptoms were detected across groups differing in sleep quality, physical activity, weekly breakfast frequency, and history of low back or neck pain ( χ 2=9.33-151.83, all P <0.05). After adjusting for confounding factors, Logistic regression revealed that the moderate and high PFI groups had significantly reduced risks of depressive and anxiety compared to the low PFI group ( OR =0.73, 0.63; 0.61, 0.72, all P <0.05). Poor speed (50 m run) and lower body strength (standing long jump) emerged as common risk factors affecting anxiety and depressive symptoms in both male and female college students (all P <0.05). Increased muscle strength (sit up for 1 min) in female students reduced the risk of depressive ( OR =0.81), anxiety ( OR =0.85), and stress symptoms ( OR =0.79) (all P <0.05). Enhanced lung capacity in male students decreased the risk of depressive ( OR =0.84) and anxiety symptoms ( OR =0.85) (both P <0.05). Conclusions The PFI is negatively correlated with depressive and anxiety symptoms among college students with notable gender differences. Insufficient speed and lower body explosive power represent common risk factors for mental health among male and female college students.

IgA nephropathy(IgAN)is one of the most prevalent forms of primary glomerulonephritis globally and a leading cause of end-stage renal disease(ESRD).The exact pathogenesis and progression mechanisms of IgAN remain unclear.Its clinical manifestations are diverse,with varying degrees of kidney involvement reflected in both clinical presentations and pathological changes.Consequently,responses to treatment and prognoses differ significantly among patients.Currently,renal needle biopsy serves as the gold standard for diagnosing IgAN;how-ever,this invasive procedure is often not well-accepted by patients,limiting its widespread clinical application and complicating disease diagnosis.Therefore,non-invasive biomarkers are crucial for assisting in the diagnosis of IgAN and evaluating the risk of disease progression.Below,we will focus on various serum and urinary biomarkers associated with IgAN at both protein and nucleic acid levels.
