Background The money.tree is a favored indoor potted plant in China. Its seeds resemble chestnuts in both shape and flavor when cooked, which are generally.considered non-Toxic and safe for consumption. Case presentation This report presents the first published case of food poisoning due to the ingestion of large amounts of money.tree seeds. A 67-y.ar-old man exhibited toxic encephalopathy.sy.ptoms and dy.pnea after consuming the seeds for approximately.6 months. After empirical mechanical ventilation, therapeutic plasma exchange, and other medical interventions, the patient's clinical status improved significantly. He was subsequently.discharged from the hospital. Conclusion Consuming a substantial quantity.of money.tree seeds within a limited timeframe can lead to poisoning, resulting in adverse outcomes, particularly.toxic encephalopathy. Moreover, plasma exchange may.have some therapeutic effect. © Wolters Kluwer Health, Inc. All rights reserved.

Decellularised extracellular matrix (dECM) is a biomaterial derived from natural tissues that has attracted considerable attention from tissue engineering researchers due to its exceptional biocompatibility.and malleability.attributes. These advantageous properties often facilitate natural cell infiltration and tissue reconstruction for regenerative medicine. Due to their excellent fluidity. the injectable hy.rogels can be administered in a liquid state and subsequently.formed into a gel state in vivo, stabilising the target area and serving in a variety.of way., such as support, repair, and drug release functions. Thus, dECM-based injectable hy.rogels have broad prospects for application in complex organ structures and various tissue injury.models. This review focuses on exploring research advances in dECM-based injectable hy.rogels, primarily.focusing on the applications and prospects of dECM hy.rogels in tissue engineering. Initially. the recent developments of the dECM-based injectable hy.rogels are explained, summarising the different preparation methods with the evaluation of injectable hy.rogel properties. Furthermore, some specific examples of the applicability.of dECM-based injectable hy.rogels are presented. Finally. we summarise the article with interesting prospects and challenges of dECM-based injectable hy.rogels, providing insights into the development of these composites in tissue engineering and regenerative medicine. © 2024, Chinese Medical Multimedia Press Co Ltd.
