Acute carbon monoxide poisoning (ACMP) is one of the most common types of poisoning worldwide, and may result in delayed encephalopathy, however, its pathogenesis remains obscure and there is no optimal treatment strategy for the patients with ACMP. Here, we developed the ACMP rat model to observe the protective effects of Buyanghuanwu decoction (BYHWD) on hippocampal neuron. BYHWD (per 5 g/kg) were intragastric administration to rats twice each day for 28 days after ACMP. In ACMP + BYHWD group rats, the neuronal injury in the hippocampal region was significantly less than that of ACMP group’s. BYHWD of intragastric administration also markedly decreased the expression of the TLR4, MyD88, NF-κB P65 after acute carbon monoxide poisoning (P<0.05). TNF-α、IL-1β protein level in ACMP + BYHWD group was lower than that of ACMP group (P<0.05). Our results suggested that decreased the activation of TLR4- NF-κB signal pathway due to BYHWD may partially account for its effect of neuroprotection standing against ACMP, and inhibited the inflammatory reaction to promote the ability recovery of learning and memory in ACMP rats.

AbstractObjectives:To demonstrate the usefulness of N-Terminal Pro-B-Type natriuretic peptide (NT-proBNP) as an early biomarker of carbon monoxide-induced myocardial injury in children. It also aimed to identify the correlation between NT-proBNP and left ventricular systolic dysfunction findings shown by echocardiography.Methods:Prospective, observational study conducted at a paediatric emergency department between October 2017 and April 2019 which involved children aged 0–17 years. The patients were divided into three groups based on severity; mild, moderate and severe groups. The patient characteristics, carboxyhaemoglobin, CK-MB Mass (CKMB-M), troponin-T, and NT-proBNP levels were measured, and echocardiography was performed and left ventricular ejection fraction was measured.Results:Sixty-nine patients and 60 healthy controls were included. Male gender, younger age, higher carboxyhaemoglobin levels, and altered mental status were found as independent predictors of carbon monoxide-induced myocardial injury. If the cut-off value for NT-proBNP level is >480 pg/ml, the sensitivity–specificity for decreased left ventricular ejection fraction, which is the strongest carbon monoxide-induced myocardial injury sign, were 100–96%, respectively. A high negative correlation was found between NT-proBNP levels and left ventricular ejection fraction (r = −0.769, p < 0.01) in the carbon monoxide poisoning group, and there was a positive correlation between the carboxyhaemoglobin and NT-proBNP levels (r = 0.583, p < 0.01).Conclusion:Echocardiography is an ideal tool and very sensitive, but its routine use is limited due to its non-availability. An increased level of NT-proBNP (>480pg/ml) may be useful as an ideal biomarker for early detection of carbon monoxide-induced myocardial injury sign and reduced left ventricular ejection fraction which is the most crucial point in making a decision on hyperbaric oxygen therapy.
