Abstract
Icariin exerts antioxidative and anti-inflammatory effects and is used in the treatment of bronchial asthma. However, the specific modes of action are uncertain. In this study, we investigated whether icariin could modulate the silencing information regulator 2-related enzyme 1 (SIRT1)/adenosine monophosphate-activated protein kinase (AMPK)/peroxisome proliferator-activated receptor gamma co-activator 1α (PGC-1α) axis by regulating miR-138-5p during H2O2-induced proliferation of mouse airway smooth muscle cells (ASMCs). Primary BALB/c mouse ASMCs were cultured using the tissue block adherence method and were induced with hydrogen peroxide (H2O2; 200 μmol/L) to establish a bronchial asthma ASMC proliferation model. With the aid of Western Blot and quantitative real-time polymerase chain reaction (qRT-PCR) in H2O2-induced ASMCs, the expression of miR-138-5p, SIRT1, AMPK, PGC-1α, α-smooth muscle actin (α-SMA), transforming growth factor-β1 (TGF-β1), collagen I, and collagen III protein and mRNA were investigated. The proliferation rate and activities of superoxide dismutase1 (SOD1), reduced glutathione (GSH), malonaldehyde (MDA), and reactive oxygen species (ROS) in ASMCs were determined. The results suggest Compared with the H2O2-induced group, icariin inhibited the miR-138-5p expression; enhanced SIRT1, p-AMPK, and PGC-1α expression; attenuated MDA activity and ROS level; lowered TGF-β1, collagen I, and collagen III expression levels; and decreased the proliferation of ASMCs induced by H2O2. The dual-luciferase reporter gene assay results showed that SIRT1 is a regulatory target of miR-138-5p.The results suggest that Icariin could improve the H2O2-induced proliferation of ASMCs. The mechanism may be related to the increase of activation of SIRT1/AMPK/PGC-1α axis by suppressing the expression of miR-138-5p. Thus, SIRT1 is the regulatory target of miR-138-5p.

Abstract
"Exterior-interior correlation between the lung and large intestine" is one of the important contents of traditional Chinese medicine. This theory describes the role of the lung and the intestine in association with disease treatment. The "lung-gut" axis is a modern extension of the "exterior-interior correlation between lung and large intestine" theory in TCM. Sirtuin (SIRT) is a nicotinamide adenine dinucleotide (NAD+)-dependent enzyme family with deacetylase properties, which is highly conserved from bacteria to humans. The sirtuin defines seven silencing regulatory proteins (SIRT1-7) in human cells. It can regulate aging, metabolism, and certain diseases. Current studies have shown that sirtuins have dual characteristics, acting as both tumor promoters and tumor inhibitors in cancers. This paper provides a comparative summary of the roles of SIRT1-7 in the intestine and lung (both inflammatory diseases and tumors), and the promoter/suppressor effects of targeting SIRT family microRNAs and modulators of inflammation or tumors. Sirtuins have great potential as drug targets for the treatment of intestinal and respiratory diseases. Meanwhile, it may provide new ideas of future drug target research.

Abstract
The aim of this study was to investigate the efficacy and underlying mechanism of high concentration of hydrogen on lipopolysaccharide (LPS)-induced acute lung injury (ALI). We have established a corresponding mouse model and examined the function of hydrogen inhalation on lung pathology and pulmonary edema induced by LPS, as well as contents of IL-1β, TNF-α and IL-8. The pulmonary microvascular permeability and 66.7 % hydrogen on the expression of sirt1 and its downstream signaling molecules were tested. Results showed that 66.7 % hydrogen alleviated lung pathological changes and pulmonary edema caused by LPS, and reduced the degree of ALI by inhibiting pro-inflammatory cytokine release and oxidative stress response, thereby decreasing the expression of molecules related to intercellular adhesion. sirt1 contributed to the repair of LPS-induced ALI by hydrogen through the regulation of NF-κB and catalase expression. In conclusion, 66.7 % hydrogen protected against LPS-induced ALI by suppressing inflammatory response and oxidative stress mediated by NF-κB and catalase in a sirt1-dependent manner.
