Advances in fluorescent probes of non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) is the predominant chronic liver disease worldwide, with 20-30 % of individuals going on to develop non-alcoholic steatohepatitis (NASH), which could result in serious complications such as fibrosis, liver cirrhosis, and hepatocellular carcinoma. Since NAFLD is reversible in its early stages, early diagnosis is necessary. By using particular structural and functional designs, fluorescent probes can be made to detect NAFLD-related chemicals or biological processes with a high degree of sensitivity and selectivity.

Efficient bionic nanozyme based on AuPt NPs@ZIF-90 used for cyclic catalysis multimodal tumor therapy.

Multimodal therapy based on nanozyme is expected to become a novel option for tumor treatment. However, the catalytic efficiency of nanozymes and the hypoxia microenvironment of tumors limit the therapeutic effect of nanozymes. Herein, we screened a small molecule of midazole-2-carboxaldehyde (ICA) to prepare ZIF-90 and embedded gold and platinum nanoparticles to obtain ZAAP.

Utility of ultrasound in the perioperative phase of carotid endarterectomy and carotid artery stent implantation.

Background: This article reviews the latest research results of the use of ultrasound technology in the perioperative period of carotid endarterectomy and carotid stenting and discusses the role of ultrasound technology in accurately evaluating carotid stenosis and plaque stability, assisting in selecting the most suitable surgical method, and providing optimal perioperative imaging to guide carotid endarterectomy (CEA) and carotid artery stenting (CAS) to reduce the occurrence and progression of stroke.

Methods: The research published in recent years on the application of ultrasound in the perioperative period of CEA and CAS was reviewed through the databases of CNKI, Pubmed, and Web of Science.

Results: Ultrasound has high clinical value in preoperative screening for indications, assessing the degree of carotid artery stenosis and the nature of plaque; monitoring hemodynamic changes intraoperatively to prevent cerebral ischemia or overperfusion; and evaluating surgical outcomes postoperatively and in late follow-up review.
