Acute lung injury （ALI） is a clinically critical disease with limited treatment options and poor prognosis， with high morbidity and mortality. Pulmonary inflammation caused by trauma， infection， and other factors in vivo and in vitro can damage alveolar epithelial and vascular endothelial barriers， resulting in lung tissue congestion and edema and eventually leading to significant dyspnea and hypoxemia， It can further develop into acute respiratory distress syndrome. Oxidative stress is one of the pathogenesis of ALI. A large number of reactive oxygen species （ROS） can promote the aggregation of inflammatory cells， increase pulmonary capillary permeability， and even directly damage lung tissue. Therefore， regulating oxidative stress becomes one of the effective means to reduce the degree of lung injury. According to the theory of traditional Chinese medicine （TCM）， ALI is divided into the categories of "sudden wheezing" and "dyspnea due to wheezing". TCM treats the causes of dampness， heat， poison， and stasis by syndrome differentiation and treatment， regulates Qi and blood， and balances Yin and Yang to restore the physiological function of the lung. In recent years， a large number of studies have shown that TCM can regulate ROS through multiple targets and mechanisms and play a role in reducing lung inflammation and protecting alveolar epithelial cells and endothelial vessels， in which the nuclear factor E₂ associated factor 2 （Nrf2） antioxidant pathway plays an important role. Based on the generation and clearance of ROS， this article summarized the related mechanisms of TCM monomers， TCM pairs， and TCM compounds in regulating oxidative stress to prevent ALI， so as to provide theoretical reference for the research and development of new TCM for ALI and clinical treatment.

Skeletal muscle is the largest tissue in the human body, and it plays a major role in exerting force and maintaining metabolism homeostasis. The role of muscle transcription factors in the regulation of metabolism is not fully understood. MondoA is a glucose-sensing transcription factor that is highly expressed in skeletal muscle. Previous studies suggest that MondoA can influence systemic metabolism homeostasis. However, the function of MondoA in the skeletal muscle remains unclear.

OBJECTIVE: To investigate the effect of limb remote ischemic preconditioning (RIPC) on hepatic ischemia/reperfusion (IR) injury and the underlying mechanisms.
 METHODS: Rats were subjected to partial hepatic IR (60 min ischemia followed by 24 hours reperfusion) with or without RIPC, which was achieved by 3 cycles of 10 min-occlusion and 10 min-
reperfusion at the bilateral femoral arteries interval 30 min before ischemia. Some rats were treated with a new PPAR-γ inhibitor, T0070907, before RIPC.
 RESULTS: At the end of reperfusion, liver injury was significantly increased (increases in Suzike's injury score, AST and ALT release), concomitant with elevated oxidative stress (increases in MDA formation, MPO activity, as well as the decrease in SOD activity) and inflammation (increases in TNF-α and IL-6 levels, decrease in IL-10 content). RIPC improved liver function and reduced histologic damage, accompanied by the increased PPAR-γ activation and autophagosome formation as well as the reduced autophagosome clearance. The beneficial effects of RIPC were markedly attenuated by T0070907, an inhibitor of PPAR-γ.
 CONCLUSION RIPC exerts the protective effects on liver by activation of autophagy via PPAR-γ.
