Toxicity and Efficacy of Water-eluted Fraction from Siegesbeckiae Herba Against Human Embryonic Lung Fibroblasts / 中国实验方剂学杂志

Objective:To detect the toxicity of water-eluted fraction from Siegesbeckiae Herba （SWEF） at different concentrations against MRC-5 human embryonic lung fibroblasts and its impacts on the expression of <italic>α</italic>7 nicotinic acetylcholine receptor （<italic>α</italic>7nAChR） and inflammatory factors， so as to figure out the active components responsible for toxicity and efficacy. Method:The toxicities of SWEF at 1， 6， 10， 20， and 50 g·L^-1 against MRC-5 cells were determined by cell counting kit-8 （CCK-8） assay combined with flow cytometry and Trypan blue staining. The changes in <italic>α</italic>7nAChR expression and inflammatory factor levels before and after <italic>α</italic>7nAChR gene silencing were detected to reveal the pharmacodynamic effect of SWEF on MRC-5 cells. Result:SWEF （≥6 g·L^-1） obviously inhibited the viability of MRC-5 cells （<italic>P</italic><0.01） and promoted their apoptosis and necrosis （<italic>P</italic><0.01）， with the half-maximal inhibitory concentration （IC₅₀） being 6.03 g·L^-1. The determination of <italic>α</italic>7nAChR expression and inflammatory factor levels in MRC-5 cells showed that SWEF contained <italic>α</italic>7nAChR agonist-like substance， which enhanced <italic>α</italic>7nAChR mRNA and protein expression （<italic>P</italic><0.05， <italic>P</italic><0.01） and decreased the inflammatory factor levels （<italic>P</italic><0.05， <italic>P</italic><0.01）. SWEF down-regulated the inflammatory factors possibly by re-regulating <italic>α</italic>7nAChR mRNA expression， exhibiting a negative correlation between them （<italic>P</italic><0.01）. Conclusion:SWEF （≥6 g·L^-1） is highly toxic to MRC-5 cells. Pharmacodynamic studies have confirmed that <italic>α</italic>7nAChR agonist-like substance contained in SWEF was responsible for the elevated <italic>α</italic>7nAChR expression and reduced inflammatory cytokines. It is inferred that excessive <italic>α</italic>7nAChR agonist-like substance may trigger the toxicity of<italic> </italic>Siegesbeckiae Herba.

Psychological Support for Medical Rescue Teams in Emergencies / 中山大学学报(医学科学版)

@# Emergencies refer to those events that cause serious social harm, including natural disasters and public health events, and require emergency response. Medical rescue team is the main emergency rescue team. While carrying out the rescue mission, they are under great pressure both physically and mentally due to the unadaptability of the rescue environment, the lack of protective materials, overwork and other reasons, often resulting in fear, tension, anxiety, pessimism, self-blame and even acute stress disorder. Without timely and effective psychological support, long-term psychological problems such as post-traumatic stress disorder will remain after the event. Comprehensive psychological support includes psychological measurement of the whole rescue process, team formation before rescue and detailed psychological support intervention training, self-relaxation during rescue, basic life and safety guarantee, drug treatment, online psychological assistance, withdrawal of stressors after rescue and lifestyle reconstruction.

Mechanism Analysis of Lung Injury Induced by Water Elution Section of Siegesbeckiae Herba on Rats by 1H-NMR Metabolomics / 中国实验方剂学杂志

Objective:Metabolomics was used to analyze the dynamic changes of endogenous metabolites in serum and lung tissue of rats treated with water elution section of Siegesbeckiae Herba (SWES), and to explore the possible mechanism of lung injury and to search for the sensitive markers in serum and lung tissue. Method:SD rats were randomly divided into three groups, namely the normal group (normal saline), SWES high-dose group and SWES low-dose group (0.500, 0.125 g·kg-1·d-1). SWES was given for 4 weeks and stopped for 2 weeks. The weight and pathological examination were regarded as observation parameters. Serum and lung tissue samples were detected by nuclear magnetic resonance hydrogen spectrum (1H-NMR). The metabolites in rats were analyzed by partial least squares-discriminant analysis (PLS-DA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). Result:Lung inflammation was shown in SWES high-dose group and returned to normal after withdrawal for 2 weeks. The metabolic spectrum of SWES high-dose group was significantly different from the normal group. There were 11 metabolites were identified by 1H-NMR metabolomics, four differential metabolites were identified in serum [acetate, trimethylamine oxide (TMAO), glycine, myo-inositol] and nine differential metabolites were identified in lung tissue [lactate, acetate, phosphatidylcholine (PC), pyruvate, dimethylamine, glutamate, glycerophosphocholine (GPC), glycine, xanthine]. Lung injury was related to the disorder of pyruvate metabolism, glutamate metabolism and other pathways. Most of the metabolites in lung tissue had obviously levels of callback after drug withdrawal, which coincided with the pathological examination. Conclusion:The lung is one of the damaged organs caused by SWES, and the lung injury is reversible and may be related to energy metabolism and oxidative stress.
