Background: There have been no previous reports that apolipoprotein (apo) A-I mimetic peptide improves survival rate after myocardial infarction (MI).

Method And Results: Male C57Bl/6J mice were subjected to left coronary artery permanent ligation as a model of MI. We synthesized a novel 24-amino acid apoA-I mimetic peptide-type5 (FAMP5), which potently removes cholesterol via specific ATP-binding cassette transporter A1 (ABCA1). FAMP5 was associated with a significantly improved survival rate by protecting against cardiac rupture compared to the control. mRNA levels for eNOS, Gata-4, CTGF and ANP were significantly increased in the hearts of the FAMP5-treated group, while that for MCP-1 decreased.

Conclusion: This is the first report that high-density lipoprotein (HDL) therapy with FAMP5 improved the survival rate after MI.

We aim to compare the clinical outcomes of radical nephroureterectomy with bladder cuff removal (RNU) and segmental resection with ureteral reimplantation (RR) in Chinese patients with distal ureteral urothelial carcinoma. A retrospective analysis of medical records was performed for 922 patients found to have distal ureteral cancer, defined as below the level of the iliac vessels, with 747 patients who underwent RNU and 175 who underwent RR included in the final analysis. The primary endpoints included clinical outcomes and changes in the estimated glomerular filtration rate (eGFR).

Introduction: This retrospective study aims to evaluate the long-term efficacy and urinary toxicity of LDR-brachytherapy for localized prostate cancer.

Materials And Methods: 235 primary prostate cancer patients treated with LDR-brachytherapy and subsequently followed up in our center were included in this study. Biochemical relapse free survival (bRFS), overall survival (OS), and cancer-specific survival (CSS) were evaluated.

Objective: To investigate the optimal cut-off value of immunohistochemical marker Ki67 as a prognostic factor to predict the recurrence of non-muscle invasive bladder urothelial carcinoma (NMIBUC).

Methods: A total of 331 patients diagnosed with NMIBUC who underwent surgery in the Yongchuan Hospital and the Second Affiliated Hospital of Chongqing Medical University from January 2012 to January 2020 were finally included in this study. The optimal cut-off value of Ki67 for predicting recurrence of NMIBUC was calculated by ROC curve and Youden index.

Prognostic and clinicopathological significance of mucin family members expression in gastric cancer: a meta-analysis.

Front Oncol

January 2025

Department of Pancreatic and Gastric Surgery, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Background: Mucin family members have been reported to be widely expressed in gastric carcinoma with diverse functions. Several important mucins exert the function of tumorigenesis or progression in gastric cancer (GC). Here, we conduct this meta-analysis to evaluate the association between mucin expression and clinicopathological features in GC.

Introduction: Neoadjuvant chemotherapy (NAC) in the management of muscle-invasive bladder carcinoma has not been adopted universally. We studied the oncological outcomes and complications in patients who underwent radical cystectomy (RC) with or without NAC.

Methods: A retrospective review of patients who underwent RC with or without NAC from June 2009 to June 2020 was conducted.
