[Irreversible electroporation for the treatment of prostate cancer: An update].

Prostate cancer (PCa) is globally the most prevalent malignancy in the male genitourinary system, with a continuously ascending incidence in China. For the treatment of localized PCa, radical prostatectomy and radiotherapy have demonstrated effective suppression of the tumor, but with obvious complications that markedly compromise the life quality of the patients. Focal therapy, by targeting the principal tumor foci, can largely reduce the incidence of complications.

Single-Cell Transcriptome Analysis Reveals the Effect of MIF on Myeloid-Derived Suppressor Cells in Multiple Myeloma.

Introduction: Multiple myeloma (MM) is a highly lethal hematologic malignancy. Myeloid-derived suppressor cells (MDSCs) exert vital effects on myeloma cells in the bone marrow microenvironment. Macrophage migration inhibitory factor (MIF) is a chemokine-like inflammatory cytokine that can not only prevent the free movement of macrophages but also regulate innate and adaptive immune responses.

Case Report: Type A invasive thymoma with renal metastasis.

Thymomas are rare malignancies originating from the epithelial cells of the thymus, typically presenting in the anterior mediastinum. Despite their indolent nature and slow growth, thymomas have the potential to metastasize to various organs, including the lungs, bones, and liver. However, renal metastasis is exceedingly rare.

Novel monoterpene indole alkaloids from the fruits of Bousigonia mekongensis and their antiproliferative effects on HepG2 cells.

Three new monoterpene indole alkaloids (1-3) together with eight known alkaloids (4-11) were isolated from the fruits of Bousigonia mekongensis. Compounds 1 and 2 were the first examples of akuammicine-Aspidosperma type bisindole alkaloids. Their structures were elucidated by NNR spectra, MS data and electronic circular dichroism (ECD) spectra.

Activation of non-classical Wnt signaling pathway effectively enhances HLA-A presentation in acute myeloid leukemia.

Objective: The escape from T cell-mediated immune surveillance is an important cause of death for patients with acute myeloid leukemia (AML). This study aims to identify clonal heterogeneity in leukemia progenitor cells and explore molecular or signaling pathways associated with AML immune escape.

Methods: Single-cell RNA sequencing (scRNA-seq) was performed to identified AML-related cellular subsets, and intercellular communication was analyzed to investigate molecular mechanisms associated with AML immune escape.

Methods: From April 2022, the general personal information and clinical data of patients with suspicious prostate lesions (PI-RADS≥3) detected by 3.0T mpMRI were collected, then underwent AI-guided mpMRI-TRUS fusion-assisted transperineal prostate biopsy.

[Role of programmed cell death in the diagnosis and treatment of prostate cancer：An update].

Prostate cancer（PCa）is the most common malignant tumor in male genitourinary system. In China, the incidence of PCa is increasing significantly, which seriously endangers the physical and mental health of Chinese men. Programmed cell death（PCD）is a kind of active and orderly cell death mode, which exists widely in the process of life activities.

GDF11 slows excitatory neuronal senescence and brain ageing by repressing p21.

As a major neuron type in the brain, the excitatory neuron (EN) regulates the lifespan in C. elegans. How the EN acquires senescence, however, is unknown.

Yiqi Yangjing recipe stimulates apoptosis while suppressing the energy metabolism via under-expression of in A549 cells.

Background: Lung cancer is a malignant tumor associated with high morbidity and mortality. Yiqi Yangjing recipe (YYR) is a formula of traditional Chinese medicine (TCM) that is commonly used for the treatment of lung cancer with good clinical efficacy. The specific anti-cancer mechanism of YYR is still unknown.

[Cuproptosis-related lncRNAs to predict biochemical recurrence of prostate cancer].

Objective: To construct a cuproptosis-related lncRNA model and obtain some new ideas and methods for predicting the biochemical recurrence (BCR) of PCa.

Methods: We identified cuproptosis-related lncRNAs from the gene expression data, mutation load data and clinical data on PCa patients in the Cancer Genome Atlas (TCGA) database and divided the patients into a training group and a verification group. We constructed a prognostic risk scoring model based on the cuproptosis -related lncRNAs, verified the validity of the model by BCR-free survival analysis, logistic regression analysis and independent prognosis analysis, and visualized the results using ROC curve analysis, Kaplan-Meier survival curves and the correlation heat map.

[Exosomes in the diagnosis of prostate cancer: Advances in studies].

In recent years, the incidence of PCa in China has been increasing year by year. Early diagnosis of the malignancy and monitoring of its progression are keys to the reduction of mortality. Currently, early diagnosis of PCa is mainly achieved by determining the level of PSA.

[Basement membrane-related gene signature to predict biochemical recurrence in patients with prostate cancer after radical prostatectomy].

Objective: To construct and verify a key gene signature of the basement membrane of prostate cancer (PCa) to predict the progression and biochemical recurrence of the malignancy after radical prostatectomy.

Methods: Based on the PCa-related transcriptome, gene mutation and clinical data from the Cancer Genome Atlas Project (TCGA) database, we analyzed the differentially expressed genes (DEG) related to the basement membrane in the PCa and adjacent normal prostate tissues, and subjected them to GO function enrichment and KEGG pathway enrichment analyses. We identified prognosis-related genes from the DEGs and analyzed their mutations.

[miR-129 in the diagnosis, treatment and prediction of clinical prognosis of prostate cancer].

Objective: To explore the value of miR-129 in the diagnosis, treatment and prediction of the clinical prognosis of PCa by observing the correlation between miR-129 and the progression of the malignancy.

Methods: This retrospective analysis included 310 male patients who visited the Department of Urology of the General Hospital of Eastern Theater Command from January 2014 to January 2022, 80 as normal healthy men, 80 with BPH, and the other 150 with PCa treated by radical prostatectomy without chemotherapy, radiotherapy or androgen-deprivation therapy. We determined the miR-129 expression in the serum and prostatic tissue of all the subjects by real-time quantitative PCR (RT-qPCR), performed pathological grading of the primary cancerous and pericancerous (≥ 3 cm from the focus) prostate tissues from the 150 PCa patients, collected the demographic and clinical data on all the subjects, and analyzed the correlation of their demographic data with the clinical parameters.

Their structures were elucidated on the basis of spectroscopic data.

Interfering with Rac1-activation during neonatal monocyte-macrophage differentiation influences the inflammatory responses of M1 macrophages.

Necrotizing enterocolitis (NEC) is a life-threatening, inflammatory disease affecting premature infants with intestinal necrosis, but the mechanism remains unclear. Neonatal macrophages are thought to play an important role in the pathogenesis of NEC through the production of proinflammatory cytokines. Restriction of cytokine expression in macrophages of NEC tissues may be beneficial.

[Characteristics of Antibiotic Contamination of Soil in China in Past Fifteen Years and the Bioremediation Technology: A Review].

In recent years, the contamination of antibiotics and their resistance genes (ARGs) has attracted the extensive attention of researchers at home and abroad. Soil is an important sink for the migration and transformation of antibiotics and ARGs, which pose a threat to soil organisms and human health. According to the relevant investigations in the past 15 years, the soil has been polluted by antibiotics to varying degrees in China.

Management of regional citrate anticoagulation for continuous renal replacement therapy: guideline recommendations from Chinese emergency medical doctor consensus.

Continuous renal replacement therapy (CRRT) is widely used for treating critically-ill patients in the emergency department in China. Anticoagulant therapy is needed to prevent clotting in the extracorporeal circulation during CRRT. Regional citrate anticoagulation (RCA) has been shown to potentially be safer and more effective and is now recommended as the preferred anticoagulant method for CRRT.
