Triple-negative breast cancer (TNBC) is a highly aggressive malignancy predominantly managed via chemotherapy. Our clinical sample analysis revealed a significant correlation between elevated CD24 expression in TNBC tumor cells and patient survival rates. We developed a novel antibody-drug conjugate (ADC), named HN03, consisting of an antibody with engineered cysteines for site-specific conjugation with a low toxic nitric oxide (NO) precursor as its payload through a novel Pt(IV)-mediated bioorthogonal self-cleavable linker. HN03 specifically targets tumor cells expressing high levels of CD24, concurrently generating cisplatin and releasing NO upon activation. HN03 also exhibited potent in vitro and in vivo antitumor activity. It significantly reduced tumor growth at various doses, prevented tumor metastasis, with markedly lower toxicity than traditional chemotherapy agents. We found that a key mechanism of its action involved inducing apoptosis and endoplasmic reticulum stress, substantially decreasing the number of M2-type macrophages. Overall, HN03 stands out as a promising therapeutic option for TNBC, offering a targeted treatment with reduced side effects and the potential for improved outcomes. Furthermore, using Pt(IV) in the linker and an NO precursor as the payload enhances the versatility of the Antibody-NO donor Conjugate (ANC), offering new avenues for the design of the next generation of ADCs.

JMJD1C (Jumonji Domain Containing 1C), a member of the lysine demethylase 3 (KDM3) family, is universally required for the survival of several types of acute myeloid leukemia (AML) cells with different genetic mutations, representing a therapeutic opportunity with broad application. Yet how JMJD1C regulates the leukemic programs of various AML cells is largely unexplored. Here we show that JMJD1C interacts with the master hematopoietic transcription factor RUNX1, which thereby recruits JMJD1C to the genome to facilitate a RUNX1-driven transcriptional program that supports leukemic cell survival. The underlying mechanism hinges on the long N-terminal disordered region of JMJD1C, which harbors two inseparable abilities: condensate formation and direct interaction with RUNX1. This dual capability of JMJD1C may influence enhancer-promoter contacts crucial for the expression of key leukemic genes regulated by RUNX1. Our findings demonstrate a previously unappreciated role for the non-catalytic function of JMJD1C in transcriptional regulation, underlying a mechanism shared by different types of leukemias.

In recent years,public hesitancy to vaccinate has come to the fore and can hinder the advancement of immunization programs.It is important to increase public confidence in vaccines and to rationally and effectively promote the immunization behavior of the population.Based on behavioral economics theory,it combines the anchoring effect,loss aversion,two-systems theory,and the herd effect to explore the irrational factors and decision-making preferences behind the public's vaccination decisions,and then proposes discourse strategies for effective boosting to increase the public's confidence in vaccination.

BackgroundCombination of antipsychotic drugs and modified electroconvulsive therapy (MECT) is currently a commonly used method for treating schizophrenia, but its efficacy varies among different patient groups. ObjectiveTo explore the therapeutic effects of MECT on schizophrenia patients living in different urban versus rural environments, so as to provide references for the selection of treatment plans based on patients' residence. MethodsA total of 587 patients hospitalized at Luzhou Mental Health Center, Zigong Mental Health Center and Yibin Fourth People's Hospital from May 2018 to August 2022, who met the diagnostic criteria for schizophrenia in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) ,were included in the study. Patients were divided into two groups: medication-only group (n=106) and MECT combined with medication group (n=481). In MECT combined with medication group, 24 rural patients residing in urban areas were excluded, leaving the remaining patients divided into urban group (n=103) and rural group (n=354) based on their place of residence. Positive and Negative Syndrome Scale (PANSS) was used to assess the severity of symptoms. Clinical efficacy was evaluated using PANSS score reduction rate, and covariance analysis was used to compare the therapeutic effects of different patients. ResultsThe differences of reduction rate of PANSS total score, positive symptom scale score and negative symptom scale score as well as treatment effectiveness rate between MECT combined with medication group and medication-only group were statistically significant (F=11.149, 12.111, 31.725, χ2=14.010, P<0.01). Statistically significant differences were also observed in reduction rate of PANSS total score and positive symptom subscale score as well as treatment effectiveness rate between urban and rural patients in MECT combined with medication group (F=3.946, 4.523, χ2=4.033, P<0.05). ConclusionThe efficacy of MECT combined with medication may be superior to medication alone in the treatment of schizophrenia, and the combined therapy may be more effective in urban patients than that in rural patients, with potentially more pronounced improvements in positive symptoms.

Objective:To construct a scientific and systematic indicator system for the ideological and political construction of medical professional courses in military medical universities, and to provide a reference for the teaching management department of military medical universities to guide and manage the ideological and political construction of courses, as well as for medical professional course instructors to carry out the ideological and political teaching of courses.Methods:On the basis of literature research and case studies, a framework of the indicator system was established for the ideological and political construction of medical professional courses in military medical universities, and six experts in the field of military medical education were invited for pre-consultation. A preliminary draft of the indicator system was formed after discussion within the research group. A total of 25 experts, who had intermediate or above professional titles and long-term experience in military medical education, teaching and management, military academy education management, and military ideological and political education in military academies, were invited to conduct two rounds of Delphi expert consultation, and a statistical analysis was performed for the consultation results to determine the indicator system for the ideological and political construction of medical professional courses in military medical universities. The percentage weight method and the product method were used to calculate the weight coefficient of each indicator and combined weight coefficient.Results:In the two rounds of expert consultation, the expert positivity coefficient was 100%, the expert authority coefficient was 0.883, and the Kendall harmony coefficients were 0.254 and 0.268, respectively ( P<0.05). Finally, an indicator system was established for the ideological and political construction of medical professional courses in military medical universities, which consisted of 5 primary indicators, 12 secondary indicators, and 31 tertiary indicators. The 5 primary indicators were the teaching objectives, teaching team, teaching resources, teaching implementation, and teaching effect of curriculum ideology and politics, with a weight coefficient of 0.210, 0.202, 0.197, 0.202, and 0.189, respectively. Conclusions:The indicator system constructed in this study is scientific, reliable, systematic, and comprehensive and has a certain guiding significance for the ideological and political construction of medical professional courses in military medical universities.
