Abstract
Background: Acute lung injury (ALI) is a complicated and severe lung disease, which is often characterized by acute inflammation. Poliumoside (POL), acteoside (ACT) and forsythiaside B (FTB) are phenylethanoid glycosides (PGs) with strong antioxidant, anti-inflammatory, and anti-apoptotic properties, which are extracted from Callicarpa kwangtungensis Chun (CK). The aim of this study was to investigate the protective effects of POL, ACT, and FTB against TNF-α-induced damage using an ALI cell model and explore their potential mechanisms. Methods and Results: MTT method was used to measure cell viability. Flow cytometry was used for detecting the apoptosis rate. Reactive oxygen species (ROS) activity was determined using fluorescence microscope. The expression of mRNA in apoptosis-related genes (Caspase 3, Caspase 8, and Caspase 9) were tested by qPCR. The effects of POL, ACT, FTB on the activities of nuclear factor erythroid-2 related factor 2 (Nrf2), nuclear factor kappa-B (NF-κB) and the expression of their downstream genes were assessed by western blotting and RT-PCR in A549 cells. In the current study, POL, ACT, and FTB dose-dependently attenuated TNF-α-induced IL-1β, IL-6 and IL-8 production, cell apoptosis, the expression of apoptosis-related genes (Caspase 3, Caspase 8, and Caspase 9) and ROS activity. POL, ACT, and FTB not only increased in the mRNA levels of antioxidative enzymes NADPH quinone oxidoreductase (NQO1), glutamate cysteine ligase catalytic subunit (GCLC), heme oxygenase (HO-1), but also decreased the mRNA levels of IL-1β, IL-6 and IL-8. Furthermore, they upregulated the expression of Keap1 and enhanced the activation of Nrf2, while decreased the expression of phosphor-IκBα (p-IκBα) and nuclear p65. In addition, no significant changes were observed in anti-inflammatory and antioxidant effects of POL, ACT, FTB following Nrf2 and NF-κB p65 knockdown. Conclusion: Our study revealed that POL, ACT, and FTB alleviated oxidative damage and lung inflammation of TNF-α-induced ALI cell model through regulating the Nrf2 and NF-κB pathways.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, irreversible interstitial lung disease, with no effective cure. Polydatin is a resveratrol glucoside with strong antioxidant, anti-inflammatory and anti-apoptotic properties, which is used for treating health-related disorders such as cardiac disabilities, various types of carcinoma, hepatitis and hepatic fibrosis. The present study aimed to investigate the protective effect of polydatin against bleomycin-induced IPF and the possible underlying mechanism. A549 cells were treated with transforming growth factor-β1 (TGF-β1) and polydatin to observe phenotypic transformation and the related gene expression was detected. Sprague-Dawley rats were divided into seven groups and intratracheally infused with bleomycin to establish a pulmonary fibrosis model (the sham control group received saline). The rats were given pirfenidone (50 mg/kg), resveratrol (40 mg/kg) and polydatin (10, 40 and 160 mg/kg) for 28 days. The results demonstrated that polydatin had low toxicity to A549 cells and inhibited TGF-β1-induced phenotypic transformation as determined by MTS assay or observed using a light microscope. It also decreased the gene expression levels of α-smooth muscle actin and collagen I and increased the gene expression levels of epithelial cell cadherin in vitro and in vivo by reverse transcription-quantitative PCR. Furthermore, polydatin ameliorated the pathological damage and fiber production in lung tissues found by hematoxylin and eosin staining and Masson trichrome staining. Polydatin administration markedly reduced the levels of hydroxyproline, tumor necrosis factor-α, interleukin (IL)-6, IL-13, myeloperoxidase and malondialdehyde and promoted total superoxide dismutase activity in lung tissues as determined using ELISA kits or biochemical reagent kits. It inhibited TGF-β1 expression and phosphorylation of Smad 2 and 3 and ERK-1 and -2 in vivo as determined by western blot assays. These results suggest that polydatin protects against IPF via its anti-inflammatory, antioxidant and antifibrotic activities, and the mechanism may be associated with its regulatory effect on the TGF-β pathway.

Abstract
Acetaminophen (APAP) overdose-induced hepatotoxicity is tightly associated with oxidative stress. Tetrahydrocurcumin (THC) and octahydrocurcumin (OHC), the primary and final hydrogenated metabolites of curcumin (CUR), possess stronger antioxidant activity in vitro. The present study was performed to investigate the potential and mechanism of OHC and THC against APAP-induced hepatotoxicity in parallel to CUR. Our results showed that OHC and THC dose-dependently enhanced liver function (ALT and AST levels) and alleviated histopathological deterioration. Besides, OHC and THC significantly restored the hepatic antioxidant status by miring level of MDA and ROS, and elevated levels of GSH, SOD, CAT and T-AOC. In addition, OHC and THC markedly suppressed the activity and expressions of CYP2E1, and bound to the active sites of CYP2E1. Moreover, OHC and THC activated the Keap1-Nrf2 pathway and enormously enhanced the translational activation of Nrf2-targeted gene (GCLC, GCLM, NQO1 and HO-1) against oxidative stress, via inhibiting the expression of Keap1 and blocking the interaction between Keap1 and Nrf2. Particularly, OHC and THC exerted superior hepato-protective and antioxidant activities to CUR. In conclusion, OHC and THC possess favorable hepato-protective effect through restoring antioxidant status, inhibiting CYP2E1 and activating Keap1-Nrf2 pathway, which might represent promising antioxidants for the treatment of APAP-induced hepatotoxicity.

Abstract
Bleomycin (BLM) is a broad spectrum anti-tumor drug and inducing pulmonary fibrosis. As an anti-tumor drug without immunosuppression, it is urgent to find a drug that reduces the side effects of BLM. Scutellarin (SCU), a flavone extracted from Erigeron breviscapus (Vant.) Hand-Mazz, has anti-inflammatory activity and ability to inhibit tumor cell growth, migration, and invasion. However, the combined role of SCU and BLM treatment in tumor is unclear. This study aimed to investigate the possible effect and related mechanisms of BLM combined with SCU in the treatment of tumor through in vivo and in vitro experiments. In vivo experiments showed that BLM combined with SCU in the treatment of mice bearing H22 ascites tumor prolonged the survival time, alleviated BLM-induced pulmonary fibrosis, reduced the production of TNF-α; IL-6, and the levels of MDA and MPO. BLM combined with SCU increased the apoptotic rate of H22 ascites cells and the levels of cleaved-caspases-3 and -8. Furthermore, BLM combined with SCU increased the protein expression of p53 and gene expression of miR-29b, and decreased the expression of TGF-β1. In vitro experiment results showed that BLM combined with SCU inhibited the viability of H22 cells and MRC-5 cells, promoted H22 cell apoptosis, up-regulated the protein expression of p53 and down-regulated the protein expression of α-SMA and collagen-I in MRC-5 cells. These experimental results suggested that SCU could enhance the anti-tumor effect of BLM and reduce BLM-induced pulmonary fibrosis, indicating SCU as a potential adjuvant for BLM in the future.

Protective role of β-patchoulene from Pogostemon cablin against indomethacin-induced gastric ulcer in rats: Involvement of anti-inflammation and angiogenesis. Phytomedicine 2018; 39:111-118.

Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) are most widely used as effective anti-inflammatory agents. However, their clinical application brings about inevasible gastrointestinal side effects. Pogostemon cablin is a traditional herbal medicine used for the treatment of gastrointestinal diseases in China. One of its representative components, the tricyclic triterpenoid β-patchoulone (β-PAE) has demonstrated great anti-inflammatory activity and gastroprotective effect against ethanol-induced gastric injury, but its protective effect against gastric ulcer induced by indomethacin is still unknown. PURPOSE To assess the protective effect of β-PAE against ulcer produced by indomethacin and reveal the underlying pharmacological mechanism. STUDY DESIGN We used an indomethacin-induced gastric ulcer model of rats in vivo. METHODS Gastroprotective activity of β-PAE (10, 20, 40 mg/kg, i.g.) was estimated via indomethacin-induced gastric ulcer model in rats. Histopathological and histochemical assessment of ulcerated tissues were performed. Protein and mRNA expression were determined by Elisa, Western blotting and qRT-PCR. RESULTS β-PAE could inhibit ulcer formation. Histopathological and histochemical assessment macroscopically demonstrated that β-PAE alleviates indomethacin-induced gastric ulceration in dose-dependent manner. After administration of β-PAE, elevated tumor necrosis factor -α level was significantly decreased and the phosphorylation of JNK and IκB was markedly inhibited. β-PAE suppressed the levels of E-selectin, P-selectin, intercellular adhesion molecule-1, vascular cell adhesion molecule and monocyte chemoattractant protein 1, as well as myeloperoxidase. Meanwhile, β-PAE increased cyclooxygenase enzyme activities (COX-1 and COX-2) to enhance the production of prostaglandin E2. Proangiogenic protein, vascular endothelial growth factor and its receptor fms-like tyrosine kinase-1 mRNA expression were promoted while anti-angiogenic protein, endostatin-1 and its receptor ETAR mRNA expression were decreased. CONCLUSION β-PAE may provide gastroprotection in indomethacin-induced gastric ulcer in rats by reducing inflammatory response and improving angiogenesis.
