The Chinese Guidelines for Ultrasound-guided Thermal Ablation of Thyroid Nodules (2024 edition) were jointly initiated by the Ultrasound Committee of Chinese Medical Association, the Interventional Ultrasound Committee of Chinese Association of Ultrasound in Medicine and Engineering, the Ultrasonic Intervention Committee of Chinese Colleges of Interventionalists, the Oncological Intervention Committee of Chinese Research Hospital Association, 37 multidisciplinary experts in interventional ultrasound, ultrasound medicine, endocrinology and thyroid surgery participated in the compilation of this guide, which expanded the depth and breadth of the perspective and enhanced the authority of the guide. Based on the systematic review of literatures related to ultrasound-guided thermal ablation of thyroid nodules and the professional opinions of experts, the guidelines define the indications and contraindications of thermal ablation, including pre-ablation evaluation and preparation, thermal ablation techniques and operational procedures, post-ablation follow-up, therapeutic effect evaluation, complications prevention and treatment, and the writing of medical documents for ablation. According to the Grading of Recommendations Assessment, Development and Evaluation (GRADE), a total of 17 objective and comprehensive recommendations were given.

Background: At present, the main clinical application of local ablation therapy, such as radiofrequency ablation (RFA), is to heat the tissue to a certain temperature. However, high temperature will cause thermal damage. Irreversible electroporation (IRE) is a novel minimally invasive local ablation technology for tumors.

Background: Researches comparing laparoscopic liver resection (LLR) with microwave ablation (MWA) for 3-5 cm multifocal hepatocellular carcinoma (MFHCC) are rare.

Materials And Methods: From 2008 to 2019, 666 intrahepatic tumours in 289 patients from 12 tertiary medical centres in China were included in this retrospective study. Propensity score matching (PSM) was performed to balance variables between the two treatment groups over time frames 2008-2019 and 2013-2019 to observe the potential impact of advancements in intervention techniques on overall survival (OS), disease-free progression (DFS) of patients.

Background: In recent years, there have been numerous studies using Quality Intima-Media Thickness (QIMT) and Quantitative Arterial Stiffness (QAS) technology to evaluate various related factors and disease-induced changes in carotid artery (CA) elasticity. However, there is still a lack of research on the relationship between non-alcoholic fatty liver disease (NAFLD) and various indicators related to the CA. This study aimed to investigate the clinical significance of using QIMT and QAS techniques for comprehensive evaluation of CA intima-media thickness (IMT) and elasticity changes in NAFLD patients, and to analyze various factors influencing these variables.

Artificial intelligence (AI) is defined as the theory and development of computer systems able to perform tasks normally associated with human intelligence. At present, AI has been widely used in a variety of ultrasound tasks, including in point-of-care ultrasound, echocardiography, and various diseases of different organs. However, the characteristics of ultrasound, compared to other imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), poses significant additional challenges to AI.

Objective: The present study aimed to assess the efficacy of this approach and establish the criteria that identify LAPC patients who may achieve survival benefits from RRCIA.

Summary Background Data: Surgical resection for locally advanced pancreatic cancer (LAPC) remains challenging and associated with high morbidity and mortality, especially for surgery with major arterial reconstruction. We previously showed the feasibility and safety of Radical Resection Combined with Intestinal Autotransplantation (RRCIA) after systemic treatment.

Article Synopsis
  • Acute rejection (AR) after heart transplantation is a major complication, prompting this study to explore using ultrasound-targeted microbubbles loaded with sirolimus (SIR-MBs) to improve outcomes in a rat model.
  • The research involved comparing three treatment groups: a control, SIR-MBs with ultrasound targeting, and direct sirolimus, assessing their effects on survival, inflammation, and specific cellular pathways.
  • Results indicated that the SIR-MBs with ultrasound targeting significantly enhanced local drug delivery, reduced inflammatory response, and affected key signaling pathways and autophagy, suggesting a promising method for improving AR treatment in heart transplant patients.

Objectives: This study aimed to develop a quantitative intratumoral heterogeneity (ITH) model for assessing the risk of early recurrence (ER) in pre-treatment multimodal imaging for hepatocellular carcinoma (HCC) patients undergoing ablation treatments.

Methods: This multi-centre study enrolled 633 HCC patients who underwent ultrasound-guided local ablation between January 2015 and September 2022. Among them, 422, 85, 57 and 69 patients underwent radiofrequency ablation (RFA), microwave ablation (MWA), laser ablation (LA) and irreversible electroporation (IRE) ablation, respectively.

Article Synopsis
  • The study aimed to assess how recovery from SARS-CoV-2 infection during early pregnancy affects fetal heart function and blood flow.
  • Researchers examined 60 women who had recovered from the virus and 20 control women through ultrasound measurements of heart function and hemodynamics between 11 and 14 weeks of pregnancy.
  • The results showed no significant differences in cardiac function or hemodynamics between the two groups, suggesting that early pregnancy COVID-19 infections do not majorly impact fetal health, but further research is needed to explore later stages of pregnancy.

Optical-resolution photoacoustic endoscopy (OR-PAE) has been proven to realize imaging on the vascular network in the gastrointestinal (GI) tract with high sensitivity and spatial resolution, providing morphological information. Various photoacoustic endoscopic catheters were developed to improve the resolution and adaptivity of imaging. However, this technology has not yet been validated on GI tumors, which generally feature angiogenesis.
