The five-paced viper (Deinagkistrodon acutus) is a prevalent venomous snake in China. Its venom comprises metalloproteinases, phospholipase A2, C-type lectin-like proteins, and serine proteases, which can induce acute reactions such as tissue inflammation, edema, necrosis, hemorrhage, coagulopathy, and even multiple organ failure. This report details a case involving a child in a rural area of China who was accidentally bitten by Deinagkistrodon acutus while playing outdoors and subsequently died despite treatment. The autopsy findings and histopathological results may assist in the clinical management and forensic practice related to Deinagkistrodon acutus envenomation in the future.

Snakebite envenomings continue to represent a major public health concern in Taiwan because of the presence of various venomous snakes whose habitats intersect with human activities. This review provides a comprehensive analysis of the clinical characteristics, complications, and management strategies associated with snakebite envenomings in Taiwan. Taiwan is inhabited by six principal venomous snakes: , , , , , and , each presenting distinct clinical challenges.

Background: To explore the mechanism of hyperbaric oxygen (HBO) intervention on acute lung injury secondary to snake venom poisoning and provide more toxicological and clinical evidence for venom poisoning.
Methods: Male Kunming mice (n = 96) were randomly divided into four groups: the control group which was not given any interventional treatments, venom group in which each mouse was injected with venom (1 mg/kg) through the tail vein, antivenom group in which each mouse was injected with anti- venom immediately after the model was successfully established, and HBO+antivenom group in which each mouse was given HBO treatment at 1 h, 5 h, 11 h and 23 h following the injection of antivenom. Lung tissues of mice were obtained and processed for the detection of the lung coefficient, the levels of inflammatory factors such as interleukin (IL)-6, IL-10 and IL-17, and the protein expression of retinoic acid receptor (RAR)-related orphan receptor gamma (RORγt) and forkhead box P3 (FOXP3).

Snake envenomation poses significant medical challenges, particularly in subtropical and tropical regions, with long-term impacts on neurovascular integrity and neuroinflammation remaining underexplored. This study investigates the effects of venom from four species of venomous snakes in southern China-Zhoushan Cobra (Naja atra, NA), Many-banded Krait (Bungarus multicinctus, BM), Five-paced Pit Viper (Deinagkistrodon acutus, DA), and Chinese Moccasin (Protobothrops mucrosquamatus, PM) - on the blood-brain barrier (BBB) and chronic neuroinflammation. Using mass spectrometry, we analyzed venom protein compositions, while cytotoxic effects on mouse brain endothelial cells (bEND.

Snakebite primarily impacts rural communities of Africa, Asia, and Latin America. The sharp-nosed viper (Deinagkistrodon acutus) is among the snakes of highest medical importance in Asia. Despite various studies on its venom using modern venomics techniques, a comprehensive understanding of composition and function of this species' venom remains lacking.
