Tumor-associated macrophages (TAMs) are the predominant immune cells in the tumor microenvironment (TME). They have been shown to play an important immunosuppressive role in the development of TME and promote tumor immune escape, growth and metastasis. It is a current research hotspot to regulate the functional polarization of TAMs through trained immunity (metabolic reprogramming, epigenetic remodeling) to affect the occurrence and development of tumors. Therefore, in-depth research in this field not only presents a more comprehensive perspective on the pathogenesis of immune-mediated diseases, but also can provide new strategies for clinical anti-tumor immunotherapy. This paper outlines the origin of TAMs and the phenotypes and mechanisms of TAMs polarization, discusses the mechanisms by which metabolic reprogramming and epigenetic remodeling regulate TAMs, summarizes the regulation of TAMs activation and polarization by them, and provides an overview of the progress in TAMs at the current stage of clinical practice, hoping to provide reference for the development of new immunoprevention and treatment strategies.

Diffuse large B-cell lymphoma (DLBCL) can be caused by multiple factors, including virus and autoimmune function, which in turn trigger persistent activation of the B-cell receptor (BCR) signaling pathway and other related signaling pathways, which collectively promote malignant B-cell proliferation and lead to tumor formation. Studies have shown significant progress in the treatment of primary and relapsed/refractory DLBCL with Bruton tyrosine kinase inhibitor (BTKi) in combination with chemotherapy, immunotherapy and small molecule inhibitors in the setting of poor outcome with BTKi monotherapy. This article reviews the progress of BTKi combined regimens in DLBCL.

The FMS-like tyrosine kinase 3 (FLT3) gene mutation is the most common genetic mutation in acute myeloid leukemia (AML) and is associated with poor prognosis. Various targeted inhibitors have been developed for FLT3 mutations and have shown promising clinical efficacy. However, the emergence of resistance poses new challenges for targeted therapy in AML. This article provides an overview of the pathological and prognostic role of FLT3 mutations in AML, the current research progress on commonly used FLT3 inhibitors (type I and type II), the mechanisms of FLT3 inhibitor resistance, and strategies for overcoming resistance.

OBJECTIVE:
To explore whether casticin (CAS) suppresses stemness in cancer stem-like cells (CSLCs) obtained from human cervical cancer (CCSLCs) and the underlying mechanism.
METHODS:
Spheres from HeLa and CaSki cells were used as CCSLCs. DNA methyltransferase 1 (DNMT1) activity and mRNA levels, self-renewal capability (Nanog and Sox2), and cancer stem cell markers (CD133 and CD44), were detected by a colorimetric DNMT activity/inhibition assay kit, quantitative real-time reverse transcription-polymerase chain reaction, sphere and colony formation assays, and immunoblot, respectively. Knockdown and overexpression of DNMT1 by transfection with shRNA and cDNA, respectively, were performed to explore the mechanism for action of CAS (0, 10, 30, and 100 nmol/L).
RESULTS:
DNMT1 activity was increased in CCSLCs compared with HeLa and CaSki cells (P<0.05). In addition, HeLa-derived CCSLCs transfected with DNMT1 shRNA showed reduced sphere and colony formation abilities, and lower CD133, CD44, Nanog and Sox2 protein expressions (P<0.05). Conversely, overexpression of DNMT1 in HeLa cells exhibited the oppositive effects. Furthermore, CAS significantly reduced DNMT1 activity and transcription levels as well as stemness in HeLa-derived CCSLCs (P<0.05). Interestingly, DNMT1 knockdown enhanced the inhibitory effect of CAS on stemness. As expected, DNMT1 overexpression reversed the inhibitory effect of CAS on stemness in HeLa cells.
CONCLUSION
CAS effectively inhibits stemness in CCSLCs through suppression of DNMT1 activation, suggesting that CAS acts as a promising preventive and therapeutic candidate in cervical cancer.

Objective:To explore the difference of the vessel and plaque characteristics, myocardial perfusion and cardiac function between patients with ischemia with non-obstructive coronary artery disease (INOCA) and obstructive coronary artery disease (CAD).Methods:From July 2021 to June 2022, 101 patients with angina were referred to dynamic computed tomography myocardial perfusion (CTP) and coronary computed tomography angiography (CCTA) and retrospectively included in our hospital. Based on the results of CTP and CCTA, patients were divided into INOCA (27 cases), moderate obstructive CAD (26 cases) and severe obstructive CAD (48 cases). The anatomical coronary artery stenosis, plaque characteristics and myocardial perfusion features of all patients were analyzed. Furthermore, left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), and global radial strain (GRS) were obtained on full-phase reconstruction CCTA image by using Medis Suite 3.2 postprocessing software. Multigroup analysis used one way ANOVA or Kruskal Wallis H test. Results:Patients with INOCA were younger than patients with moderate and severe obstructive CAD ( P<0.001). INOCA patients (7.4%, 2/27) had lower rate of positive remodeling than both moderate (57.7%, 15/26, P<0.001) and severe obstructive CAD patients (33.3%, 16/48, P=0.017). The percentage of ischemic myocardium volume in patients with INOCA were similar with those in patients with severe CAD (all P>0.05), but significantly higher than those in patients with moderate CAD (all P<0.05). No significant difference in terms of GLS was detected between patients with INOCA [-17.4% (-21.6%, -11.6%)] and severe CAD [-17.6% (-21.9%, -14.8%), P=0.536], however, patients both with INOCA and severe CAD also had higher GLS than patients with moderate obstructive CAD [-22.3% (-29.8%, -19.0%), all P<0.05]. Conclusions:Based on"one-stop-shop"CTP combined with CCTA imaging, early cardiac functional changes including abnormal myocardial perfusion and myocardial strain in INOCA patients were similar to those in patients with severe obstructive CAD and more severe than those in patients with moderate obstructive CAD.
