Causal Relationship between Meat Intake and Biological Aging: Evidence from Mendelian Randomization Analysis.

Existing research indicates that different types of meat have varying effects on health and aging, but the specific causal relationships remain unclear. This study aimed to explore the causal relationship between different types of meat intake and aging-related phenotypes. This study employed Mendelian randomization (MR) to select genetic variants associated with meat intake from large genomic databases, ensuring the independence and pleiotropy-free nature of these instrumental variables (IVs), and calculated the F-statistic to evaluate the strength of the IVs.

Biphasic co-detection of melanoma aneuploid tumor cells and tumor endothelial cells in guidance of specifying the field cancerized surgical excision margin and administering immunotherapy.

An optimum safety excision margin (EM) delineated by precise demarcation of field cancerization along with reliable biomarkers that enable predicting and timely evaluating patients' response to immunotherapy significantly impact effective management of melanoma. In this study, optimized biphasic "immunofluorescence staining integrated with fluorescence insitu hybridization" (iFISH) was conducted along the diagnosis-metastasis-treatment-cellular MRD axis to longitudinally co-detect a full spectrum of intact CD31 aneuploid tumor cells (TCs), CD31 aneuploid tumor endothelial cells (TECs), viable and necrotic circulating TCs (CTCs) and circulating TECs (CTECs) expressing PD-L1, Ki67, p16 and Vimentin in unsliced specimens of the resected primary tumor, EM, dissected sentinel lymph nodes (SLNs) and peripheral blood in an early-stage melanoma patient. Numerous PD-L1 aneuploid TCs and TECs were detected at the conventional safety EM (2 cm), quantitatively indicating the existence of a field cancerized EM for the first time.

Exploring the Causal Effects of Mineral Metabolism Disorders on Telomere and Mitochondrial DNA: A Bidirectional Two-Sample Mendelian Randomization Analysis.

The aim of this study was to assess the causal relationships between mineral metabolism disorders, representative of trace elements, and key aging biomarkers: telomere length (TL) and mitochondrial DNA copy number (mtDNA-CN). Utilizing bidirectional Mendelian randomization (MR) analysis in combination with the two-stage least squares (2SLS) method, we explored the causal relationships between mineral metabolism disorders and these aging indicators. Sensitivity analysis can be used to determine the reliability and robustness of the research results.

(2) Combination of decitabine with half dose CAG chemotherapy (Acla 20 mg qod×3 d, Ara-C 10 mg/m² q12 h×7 d, G-CSF 300 μg/d, the dose of G-CSF adjust to the amount of blood routine).

[Effect of decitabine on immune regulation in patients with acute myeloid leukemia after allogeneic hematopoietic stem cell transplantation].

Based on the representative articles in recent years, the different mechanisms of decitabine on immune regulation in patients with acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (HSCT) are summarized. Decitabine improves the expression of WT1 gene to stimulate specific cytotoxic T cells which can enhance graft versus leukemia effect (GVL) and improve the expression of FOXP3 gene to stimulate regulatory T cells so as to inhibit the acute graft versus host disease (GVHD). Through the above-mentimed mechanisms, decitabine can improve both therapeutic effect and quality of life in the patients with AML after allogeneic HSCT.
