作者： Chunjie Wang Lei Zhang Zhijuan Yang Dongxu Zhao Zheng Deng Jialu Xu Yumin Wu Yu Hao Ziliang Dong Liangzhu Feng Zhuang Liu Institute of Functional Nano & Soft Materials (FUNSOM) Jiangsu Key Laboratory for Carbon-Based Functional Materials & Devices Soochow University Center of Interventional radiology & vascular surgery Department of Radiology Zhongda Hospital Medical School Southeast University department of Interventional radiology The First Afflliated Hospital of Soochow University

Lipiodol chemotherapeutic emulsions remain one of the main choices for the treatment of unresectable hepatocellular carcinoma(HCC) via transarterial chemoembolization(TACE). However, the limited stability of Lipiodol chemotherapeutic emulsions would lead to rapid drug diffusion, which would reduce the therapeutic benefit and cause systemic toxicity of administrated chemotherapeutics. Therefore, the development of enhanced Lipiodol-based formulations is of great significance to enable effective and safe TACE treatment. Herein, a stable water-in-oil Lipiodol Pickering emulsion(LPE) stabilized by pH-dissociable calcium carbonate nanoparticles and hemin is prepared and utilized for efficient encapsulation of lipoxygenase(LOX). The obtained LOX-loaded CaCO3&hemin-stabilized LPE(LHCa-LPE) showing greatly improved emulsion stability could work as a pH-responsive and self-fueling microreactor to convert polyunsaturated fatty acids(PUFAs), a main component of Lipiodol, to cytotoxic lipid radicals through the cascading catalytic reaction driven by LOX and hemin, thus inducing ferroptosis of cancer cells. As a result, such LHCa-LPE upon transcatheter embolization can effectively suppress the progression of orthotopic N1S1 HCC in rats. This study highlights a concise strategy to prepare pH-responsive and stable LPE-based self-fueling microreactors, which could serve as bifunctional embolic and ferroptosis-inducing agents to enable proof-of-concept transarterial ferro-embolization therapy of HCC.

Total pancreatectomy(TP) is a surgical procedure which includes the complete removal of the pancreatic gland, the spleen, the duodenum, the gallbladder, and the distal part of the stomach. TP represents the curative treatment of pancreatic cancer which simultaneously involves the head and the body/tail of the pancreas. Other possible indications for TP comprise multifocal parenchymal diseases, such as intraductal papillary mucinous neoplasms, pancreatic neuroendocrine tumors, multiple endocrine neoplasms, and chronic pancreatitis. Sometimes, TP is carried out in patients scheduled for pancreaticoduodenectomy(where only the head of the pancreas is removed) when a cancer located in the pancreatic head is intraoperatively found to also extend to the pancreatic body [1].
