Abstract

Background: Fatigue is a prevalent issue that can lead individuals to a sub-health condition, impacting their work efficiency and quality of life. There are limited effective treatment options available for fatigue. Ren-Shen-Bu-Qi decoction (RSBQD) is a proprietary herbal remedy that is designed to address fatigue. However, the specific pharmacological mechanisms and basis of RSBQD are not yet fully understood.

Purpose: This study aimed to investigate the pharmacological effects and mechanisms of RSBQD in a mouse model of exercise fatigue.

Materials and methods: UPLC-Q-Orbitrap HRMS was used to analyze the chemical composition of RSBQD. The pharmacological basis and molecular mechanism of RSBQD on exercise fatigue were predicted using network pharmacology analysis. Subsequently, an exercise fatigue mouse model was established and used to analysis the effects of RSBQD. The potential mechanisms were verified by hematoxylin-eosin (HE) staining, real-time fluorescence quantitative PCR (RT-qPCR), Western blot (WB) and molecular docking.

Results: The results showed that 88 main components of RSBQD were identified, which have mainly belonged to flavonoids and carboxylic acid compounds. The network pharmacology analysis indicated that RSBQD ameliorate fatigue through PI3K/AKT signaling pathway. Notably, RSBQD prolonged the swimming time and diminished body weight loss of exercise fatigue mice (P < 0.05). Meanwhile, RSBQD significantly alleviated the injury of liver and kidney induced by exhaustive exercise, and decreasing the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea and BUN levels (P < 0.05). In addition, RSBQD was found could relieve exercise fatigue by decreasing the content of creatine kinase (CK), lactate dehydrogenase (LDH), and lactic acid (LA), but increasing the blood glucose (GLU) and liver glycogen (HG) levels (P < 0.05). RSBQD also significantly increased the hepatic superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) but decreased hepatic malondialdehyde (MDA) levels. Moreover, RSBQD was able to upregulate protein level of activated Nrf2 and PI3K/AKT signaling pathways.

Conclusions: RSBQD mitigates exercise fatigue by reversing metabolic changes and reducing oxidative damage through the PI3K/AKT/Nrf2 signaling pathway. This study offers pharmacological support for the utilization of RSBQD in exercise fatigue treatment.

人参八味汤通过激活 PI3K/AKT/Nrf2 通路缓解小鼠运动疲劳
背景:疲劳是一个普遍存在的问题,可导致个人处于亚健康状态,影响工作效率和生活质量。目前治疗疲劳的有效方法有限。人参八味汤(RSBQD)是一种专治疲劳的中药。目的:本研究旨在研究 RSBQD 在运动性疲劳小鼠模型中的药理作用和机制:采用UPLC-Q-Orbitrap HRMS分析RSBQD的化学成分。采用网络药理学分析方法预测了RSBQD对运动性疲劳的药理基础和分子机制。随后,建立了运动疲劳小鼠模型,并利用该模型分析了RSBQD的作用。通过苏木精-伊红(HE)染色、实时荧光定量 PCR(RT-qPCR)、Western 印迹(WB)和分子对接等方法验证了其潜在机制:结果表明,RSBQD的主要成分有88种,主要属于黄酮类和羧酸类化合物。网络药理学分析表明,RSBQD通过PI3K/AKT信号通路改善疲劳。值得注意的是,RSBQD可延长运动疲劳小鼠的游泳时间并减轻其体重减轻(P 结论:RSBQD可通过PI3K/AKT信号通路缓解运动疲劳:RSBQD 可通过 PI3K/AKT/Nrf2 信号通路逆转代谢变化和减少氧化损伤,从而缓解运动疲劳。这项研究为利用 RSBQD 治疗运动性疲劳提供了药理学支持。
