Autophagy is a well-conserved self-protection process that plays an important role in cardiovascular diseases. Excessive autophagy during myocardial ischemia/reperfusion injury (MIRI) induces calcium overload and the overactivation of an autophagic response, thereby aggravating cardiomyocyte damage. Polycystin-2 (PC2) is a Ca-permeable nonselective cation channel implicated in the regulation of autophagy.

Purpose: This study aims to investigate the factors influencing the malignant risk of BI-RADS 4B calcification-only lesions detected on Contrast-Enhanced Mammography (CEM) and to develop a predictive model for stratifying malignant risk.

Methods: A retrospective analysis was conducted on 131 calcification-only lesions of BI-RADS 4B identified on low-energy (LE) images of CEM from 125 females between March 2017 and April 2023 at three institutions. The patients were grouped as training (95 lesions) and external validation sets (36 lesions).

Article Synopsis
  • - The study analyzed how different types of nodule-pleural relationships (like those with pleural tail signs) affect the risk of pneumothorax during CT-guided biopsies in lung nodules.
  • - Results showed that nodules in contact with the pleura had a lower risk of pneumothorax compared to those with pleural tail signs or being pleural unrelated, highlighting the importance of nodule positioning.
  • - Key factors increasing the risk of pneumothorax included crossing pleural tail signs, longer biopsy time, deeper needle insertion, and nodules located in the middle or lower lobes.

Tumor proliferation and metastasis are intricately linked to blood vessel formation, with vascular endothelial growth factor (VEGF) playing a pivotal role in orchestrating angiogenesis throughout tumor progression. Pseudolaric acid B (PAB) has emerged as a potent inhibitor of tumor cell proliferation, migration, and angiogenesis. In efforts to enhance its efficacy, 37 derivatives of PAB were synthesized and assessed for their capacity to suppress VEGF secretion in SiHa cells under hypoxic conditions.

Objectives: To investigate whether high concentration iodinated contrast media (CM), compared with low concentration CM, could reduce pain and discomfort levels in patients who had level II and III venous conditions.

Methods: This prospective, single-center study enrolled patients who had level II and III venous conditions and underwent abdominal contrast-enhanced CT scan between July 2021 and February 2022. The venous condition to establish peripheral venous access for CM injection was graded using the Intravenous Access Scoring system, of which level II and III indicated poor venous condition and difficult venous access.

  • The study investigates the adherence of family members to a newly implemented management strategy for H. pylori infection and identifies factors influencing this adherence over a two-year follow-up of 282 families.
  • Findings indicate improved adherence rates across various recommendations, with a notable 77% for infection awareness but lower rates for treatment and gastroscopy.
  • Key factors influencing adherence included being younger (ages 18-44), having a larger family size, and being aware of symptoms, while occupation and being asymptomatic were linked to lower adherence levels.

Background: The overall benefits of the newly introduced family-based Helicobacter pylori (H. pylori) infection control and management (FBCM) and screen-and-treat strategies in preventing multiple upper gastrointestinal diseases at national level in China have not been explored. We investigate the cost-effectiveness of these strategies in the whole Chinese population.

Article Synopsis
  • Chronic methamphetamine (METH) exposure is linked to high blood pressure (hypertension) and vascular remodeling, but the exact mechanisms are not fully understood.
  • Researchers developed a mouse model to study METH's effects, discovering that the Sigma1 receptor (Sigmar1) plays a crucial role in hypertension and collagen buildup around blood vessels.
  • The study suggests that targeting Sigmar1 could be a new treatment strategy for METH-induced hypertension and related vascular issues.

Purpose: The purpose of this research was to investigate the efficacy of the CT-based peritoneal cancer index (PCI) to predict the overall survival of patients with peritoneal metastasis in gastric cancer (GCPM) after two cycles of chemotherapy.

Methods: This retrospective study registered 112 individuals with peritoneal metastasis in gastric cancer in our hospital. Abdominal and pelvic enhanced CT before and after chemotherapy was independently analyzed by two radiologists.

Background Detection of extranodal extension (ENE) at pathology is a poor prognostic indicator for rectal cancer, but whether ENE can be identified at pretreatment MRI is, to the knowledge of the authors, unknown. Purpose To evaluate the performance of pretreatment MRI in detecting ENE using a matched pathologic reference standard and to assess its prognostic value in patients with rectal cancer. Materials and Methods This single-center study included a prospective development data set consisting of participants with rectal adenocarcinoma who underwent pretreatment MRI and radical surgery (December 2021 to January 2023).

Purpose: The purpose of the current investigation is to compare the efficacy of different diffusion models and diffusion kurtosis imaging (DKI) in differentiating stage IA endometrial carcinoma (IAEC) from benign endometrial lesions (BELs).

Methods: Patients with IAEC, endometrial hyperplasia (EH), or a thickened endometrium confirmed between May 2016 and August 2022 were retrospectively enrolled. All of the patients underwent a preoperative pelvic magnetic resonance imaging (MRI) examination.

Purpose: Rectal tumor segmentation on post neoadjuvant chemoradiotherapy (nCRT) magnetic resonance imaging (MRI) has great significance for tumor measurement, radiomics analysis, treatment planning, and operative strategy. In this study, we developed and evaluated segmentation potential exclusively on post-chemoradiation T2-weighted MRI using convolutional neural networks, with the aim of reducing the detection workload for radiologists and clinicians.

Methods: A total of 372 consecutive patients with LARC were retrospectively enrolled from October 2015 to December 2017.

Article Synopsis
  • This study evaluated early contrast-enhanced magnetic resonance imaging (ECE-MR) for detecting complete tumor response in patients with esophageal squamous cell carcinoma after neoadjuvant therapy.
  • Results showed that ECE-MR had a higher diagnostic accuracy (AUC 0.85) compared to traditional methods (T2WI+DWI with AUC 0.69) and was more effective for identifying early-stage tumors.
  • The findings suggest that ECE-MR could improve clinical decision-making and support tailored treatment strategies for patients undergoing therapy for esophageal cancer.

The current review was undertaken to collate data on Gpx4 inhibitors and the regulatory proteins related to Gpx4. Gpx4 plays an essential role in ferroptosis; it can be used to determine the Gpx4 as an indicator for determining tumor occurrence and as a means of treating cancer. Although there is no market for Gpx4 inhibitors, many researchers have conducted extensive research, and some compounds have entered clinical research.

Aims: Nuclear protein 1 (Nupr1) is a multifunctional stress-induced protein involved in the regulation of tumorigenesis, apoptosis, and autophagy. However, its role in pulmonary hypertension (PH) after METH exposure remains unexplored. In this study, we aimed to investigate whether METH can induce PH and describe the role and mechanism of Nupr1 in the development of PH.

Article Synopsis
  • Around 10%-31% of patients with colorectal liver metastases (CRLM) also have hepatic lymph node metastases (LNM), which often indicates a worse prognosis and complicates surgical options due to a lack of effective preoperative assessment methods.
  • This study aimed to evaluate the effectiveness of different diffusion-weighted imaging (DWI) models in identifying benign versus malignant hepatic lymph nodes in CRLM patients who received neoadjuvant chemotherapy.
  • Results showed that a nomogram based on the DDC value and the size of lymph nodes post-treatment could reliably predict lymph node status, outperforming other methods in distinguishing between benign and malignant cases.

Background: Predicting preoperative understaging in patients with clinical stage T1-2N0 (cT1-2N0) esophageal squamous cell carcinoma (ESCC) is critical to customizing patient treatment. Radiomics analysis can provide additional information that reflects potential biological heterogeneity based on computed tomography (CT) images. However, to the best of our knowledge, no studies have focused on identifying CT radiomics features to predict preoperative understaging in patients with cT1-2N0 ESCC.
