Abstract
Sepsis is a life-threatening disease with limited treatment options, and the inflammatory process represents an important factor affecting its progression. Many studies have demonstrated the critical roles of signal transducer and activator of transcription 3 (STAT3) in sepsis pathophysiology and pro-inflammatory responses. Inhibition of STAT3 activity may therefore represent a promising treatment option for sepsis. We here used a mouse model to demonstrate that (E)-2-methoxy-4-(3-(4-methoxyphenyl)prop-1-en-1-yl)phenol (MMPP) treatment prevented the liver sepsis-related mortality induced by 30 mg/kg lipopolysaccharide (LPS) treatment and reduced LPS-induced increase in alanine transaminase, aspartate transaminase, and lactate dehydrogenase levels, all of which are markers of liver sepsis progression. These recovery effects were associated with decreased LPS-induced STAT3, p65, and JAK1 phosphorylation and proinflammatory cytokine (interleukin 1 beta, interleukin 6, and tumor necrosis factor alpha) level; expression of cyclooxygenase-2 and induced nitric oxide synthase were also reduced by MMPP. In an in vitro study using the normal liver cell line THLE-2, MMPP treatment prevented the LPS-induced increase of STAT3, p65, and JAK1 phosphorylation and inflammatory protein expression in a dose-dependent manner, and this effect was enhanced by combination treatment with MMPP and STAT3 inhibitor. The results clearly indicate that MMPP treatment prevents LPS-induced mortality by inhibiting the inflammatory response via STAT3 activity inhibition. Thus, MMPP represents a novel agent for alleviating LPS-induced liver sepsis.

Abstract
Background and objectives Dexmedetomidine has demonstrated protective effects against lung injury in vitro. Here, we investigated whether dexmedetomidine preconditioning protected against lung injury in hemorrhagic shock rats. Methods Male Sprague-Dawley rats were randomly divided into four groups (n = 8): control group, hemorrhagic shock group, 5 ug.kg−1 dexmedetomidine (DEX1) group, and 10 ug.kg−1 dexmedetomidine (DEX2) group. Saline or dexmedetomidine were administered over 20 min. 30 min after injection, hemorrhage was initiated in the hemorrhagic shock, DEX1 and DEX2 group. Four hours after resuscitation, protein and cellular content in bronchoalveolar lavage fluid, and the lung histopathology were measured. The malondialdehyde, superoxide dismutase, Bcl-2, Bax and caspase-3 were also tested in the lung tissue. Results Compare with hemorrhagic shock group, 5 ug.kg−1 dexmedetomidine pretreatment reduced the apoptosis (2.25 ± 0.24 vs. 4.12 ± 0.42%, p < 0.05), histological score (1.06 ± 0.12 vs. 1.68 ± 0.15, p < 0.05) and protein (1.92 ± 0.38 vs. 3.95 ± 0.42 mg.mL−1, p < 0.05) and WBC (0.42 ± 0.11 vs. 0.92 ± 0.13 × 109/L, p < 0.05) in bronchoalveolar lavage fluid. Which is correlated with increased superoxide dismutase activity (8.35 ± 0.68 vs. 4.73 ± 0.44 U.mg−1 protein, p < 0.05) and decreased malondialdehyde (2.18 ± 0.19 vs. 3.28 ± 0.27 nmoL.mg−1 protein, p < 0.05). Dexmedetomidine preconditioning also increased the Bcl-2 level (0.55 ± 0.04 vs. 0.34 ± 0.05, p < 0.05) and decreased the level of Bax (0.46 ± 0.03 vs. 0.68 ± 0.04, p < 0.05), caspase-3 (0.49 ± 0.03 vs. 0.69 ± 0.04, p < 0.05). However, we did not observe any difference between the DEX1 and DEX2 groups for these (p > 0.05). Conclusion Dexmedetomidine preconditioning has a protective effect against lung injury caused by hemorrhagic shock in rats. The potential mechanisms involved are the inhibition of cell death and improvement of antioxidation. But did not show a dose-dependent effect.

Abstract
BACKGROUND AND OBJECTIVES Dexmedetomidine (DEX) has demonstrated the preconditioning effect and shown protective effects against organize injury. In this study, using A549 (human alveolar epithelial cell) cell lines, we investigated whether DEX preconditioning protected against acute lung injury (ALI) in vitro. METHODS A549 were randomly divided into four groups (n=5): control group, DEX group, lipopolysaccharides (LPS) group, and D-LPS (DEX+LPS) group. Phosphate buffer saline (PBS) or DEX were administered. After 2h preconditioning, the medium was refreshed and the cells were challenged with LPS for 24h on the LPS and D-LPS group. Then the malondialdehyde (MDA), superoxide dismutase (SOD), Bcl-2, Bax, caspase-3 and the cytochrome c in the A549 were tested. The apoptosis was also evaluated in the cells. RESULTS Compare with LPS group, DEX preconditioning reduced the apoptosis (26.43%±1.05% vs. 33.58%±1.16%, p<0.05) in the A549, which is correlated with decreased MDA (12.84±1.05 vs. 19.16±1.89nmol.mg-1 protein, p<0.05) and increased SOD activity (30.28±2.38 vs. 20.86±2.19U.mg-1 protein, p<0.05). DEX preconditioning also increased the Bcl-2 level (0.53±0.03 vs. 0.32±0.04, p<0.05) and decreased the level of Bax (0.49±0.04 vs. 0.65±0.04, p<0.05), caspase-3 (0.54±0.04 vs. 0.76±0.04, p<0.05) and cytochrome c. CONCLUSION DEX preconditioning has a protective effect against ALI in vitro. The potential mechanisms involved are the inhibition of cell death and improvement of antioxidation.

Abstract
Rheumatoid arthritis (RA) is a severely debilitating chronic autoimmune disease that leads to long-term joint damage. Signal transducer and activator of transcription 3 (STAT3)-targeted small molecules have shown promise as therapeutic drugs for treating RA. We previously identified (E)-2,4-bis(p-hydroxyphenyl)-2-butenal (BHPB), a tyrosine-fructose Maillard reaction product, as a small molecule with potent anti-inflammatory and anti-arthritic properties, mediated through the inhibition of STAT3 activation. The aim of this study was to develop a novel BHPH derivative with improved anti-arthritic properties and drug-likeness. We designed and synthesised (E)-2-methoxy-4-(3-(4-methoxyphenyl) prop-1-en-1-yl) phenol (MMPP), a novel synthetic BHPB analogue, and investigated its anti-inflammatory and anti-arthritic activities in experimentally-induced RA. We showed that MMPP strongly inhibited pro-inflammatory responses by inhibiting in vitro STAT3 activation and its downstream signalling in murine macrophages and human synoviocytes from patients with RA. Furthermore, we demonstrated that MMPP exhibited potent anti-arthritic activity in a collagen antibody-induced arthritis (CAIA) mouse model in vivo. Collectively, our results suggest that MMPP has great potential for use in the treatment of RA.

Abstract
The present study investigated the apoptotic effects of fisetin, a phenolic compound, against the human nonsmall cell lung cancer cell line, NCI-H460. Fisetin showed dose-dependent cytotoxic activity against NCI-H460 cells, with 50% inhibition of cell viability occurring at a concentration of 75 μg/mL. Fisetin induced both the production of intracellular reactive oxygen species and apoptosis, as evidenced by apoptotic body formation, DNA fragmentation, an increase in the number of sub-G1 phase cells, and mitochondrial membrane depolarization. Moreover, fisetin significantly modulated the expression of apoptosis-associated proteins, resulting in reduced expression of B cell lymphoma-2, increased expression of Bcl-2-associated X protein, and activation of caspase-9 and caspase-3. In addition, pretreatment with a caspase inhibitor blocked fisetin-induced cell death.
