A fatal intractable ventricular fibrillation triggered by improper use of Xiaozhong Jiuwei Powder: integrated LC-MS chemical profiling unveils the cardiotoxic culprits.
Article in Frontiers in medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Acute poisoning from toxic substances significantly endangers human health, with poisoning-induced cardiac arrest representing a critical public health concern. Xiaozhong Jiuwei Powder (XZJWP), a traditional Chinese medicine (TCM) formulation used in Mongolian Medicine, is known for its antipyretic, analgesic, and anti-inflammatory properties. However, improper use of XZJWP can lead to severe adverse effects. Methods: In this study, we report a fatal case of refractory ventricular fibrillation in a patient admitted to our hospital in autumn 2023, following the improper use of XZJWP. Despite intensive treatment, the patient succumbed to the condition 1 week later. To identify the toxic chemicals responsible for this outcome, a comprehensive chemical profiling of XZJWP was conducted using UPLC-Q-Orbitrap-HRMS. Results: Our analysis identified 292 compounds, categorized into 24 major groups, with several toxic alkaloids detected. Notably, diester-diterpenoid alkaloids (DDAs), including aconitine, mesaconitine, and hypaconitine, were identified as key toxic compounds known to cause neurotoxicity and cardiotoxicity. Discussion: These findings warrant caution in using XZJWP and other aconite-containing TCMs, emphasizing the need for public education on safe use and improved clinical management of related poisonings. The study provides crucial guidance for healthcare professionals in diagnosing and treating such toxicities.
