Abstract
The purpose of the current study was to investigate the anti-asthmatic effect of esculetin (ES) and explore its potential mechanism with a mouse model of allergic asthma. A total number of 50 mice were randomly assigned to five groups: control, model, dexamethasone (Dex, 2 mg/kg), and ES (20 mg/kg, 40 mg/kg). Mouse asthma model was developed with the sensitization and challenge of ovalbumin (OVA). The levels of IgE in serum, eosinophilia infiltration, Th2/Th17 cytokines, Th17 cell frequency, histological condition, and the protein expressions of RORγt, GATA3 were detected. Our study demonstrated that ES inhibited, OVA-induced eosinophil count, interleukin-4 (IL-4), IL-5, IL-13, and IL-17A levels were recovered in bronchoalveolar lavage fluid. Flow cytometry (FCM) studies revealed that ES substantially inhibited Th17 cells' percentage. Western blot study also indicated that ES downregulated RORγt and GATA3 expressions. Meanwhile, ES had beneficial effects on the histological alteration. These findings suggested that ES might effectively ameliorate the progression of asthma and could be used as a therapy for patients with allergic asthma.

Abstract
The purpose of the present study was to evaluate the protective effects of astragaloside IV (AS IV) against paraquat (PQ)-induced pulmonary injury in vivo. Fifty BALB/C mice were randomized into five groups: (1) control, (2) PQ, (3) PQ + dexamethasone (Dex, 5 mg/kg), (4) PQ + AS IV (50 mg/kg), and (5) PQ + AS IV (100 mg/kg). A single dose of PQ (50 mg/kg, i.p.) was intraperitoneally given to induced acute lung injury. Then, mice were treated with AS IV (50 and 100 mg/kg/day, orally) for 5 days. At the end of the experiment, animals were euthanized; then, the bronchoalveolar lavage fluid (BALF) and lung tissues were collected for histological observation, biochemical assay, and Western blot analysis. Malondialdehyde (MDA), myeloperoxidase (MPO), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) in lung tissues, and interleukin-6 (IL-6), IL-1β, tumor necrosis factor-α (TNF-α) levels in BALF were determined. Histological examination indicated that AS IV attenuated lung damage caused by PQ. Biochemical results showed that AS IV treatment significantly reduced the levels of MDA, MPO, and inflammatory cytokines while increased the levels of SOD, CAT, and GSH-Px compared with those in PQ group. Western blot results revealed that AS IV attenuated the Txnip/Trx expressions and inhibited Rho/ROCK/nuclear factor kappaB (NF-κB) signaling pathway in PQ-challenged mice. These findings suggested the protective effect of AS IV as a natural product on PQ-induced pulmonary injury.

Abstract
The purpose of the present study was to evaluate the protective effect of betulin (BE) on CS (cigarette smoke)-induced COPD in mice and explore its underlying mechanisms. 60 male ICR mice were randomly assigned to five groups: control group, model group, dexamethasone (2mg/kg) group, BE (20mg/kg) group and BE (40mg/kg) group. The COPD mice were induced by cigarette smoke exposure for 8 weeks. The result of H&E staining demonstrated that BE inhibited CS-induced pathological injury in lung tissue. Besides, BE could restore the activities of superoxide dismutase (SOD) in serum and in lung, catalase (CAT) in serum and reduce the content of malondialdehyde (MDA) in serum and in lung. BE also inhibited the overproductions of pro-inflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β). Furthermore, the administration of BE significantly inhibited the protein expression of ROCK/NF-κB pathway in CS-induced mice. Our findings suggested that BE might effectively ameliorate the progression of COPD via ROCK/NF-κB pathway in mice.

Abstract
The present study was designed to investigate the protective effect of Sophoraflavanone G (SG) on streptozotocin (STZ)-induced diabetic rats. The rats were intraperitoneally injected with STZ (35mg/kg). 7days later, the rats were intragastrically administered with Metformin (MET, 150mg/kg), SG (20mg/kg) or SG (40mg/kg) once daily for consecutive 30 days. The animals were anaesthetized, the blood and liver samples were also collected for further assay. SG significantly decreased the serum levels of glucose, insulin, aspartate transaminase (AST), alanine aminotransferase (ALT). In addition, SG increased superoxide dismutase (SOD) activity and inhibited malondialdehyde (MDA) content in serum. SG also ameliorated the histopathological condition. Furthermore, SG attenuated the expressions of thioredoxin (Trx), thioredoxin-interacting protein (Txnip) and the phosphorylations of inhibitory kappa B kinase (IKK)α, IKKβ, nuclear factor-κB inhibitory proteins (IκB)α, nuclear factor κB (NF-κB). These findings demonstrated that SG showed beneficial effects on STZ-induced diabetic rats.

Abstract
Platycodin D (PYD), a major saponin derived and isolated from the roots of Platycodon grandiflorum, has been reported to have anti-inflammatory and anti-tumor effects. The present study aimed to investigate the effects of PYD on IL-1β-stimulated human osteoarthritis chondrocytes. Chondrocytes were treated with PYD 1h before IL-1β treatment. The levels of MMP1, MMP13, IL-8, RANTES, PGE2, and NO were measured in this study. The expression of LXRα, NF-κB, and IκBα were detected by western blot analysis. The results showed that PYD significantly inhibited IL-1β-induced MMP1, MMP13, IL-8, RANTES, PGE2, and NO production. PYD also suppressed IL-1β-induced NF-κB activation. Furthermore, the expression of LXRα was up-regulated by PYD in a dose-dependent manner. In addition, LXRα siRNA inhibited the effects of PYD on MMP1, MMP13, PGE2, and NO production in human osteoarthritis chondrocytes. In conclusion, these results suggested that PYD attenuated IL-1β-induced inflammatory response in osteoarthritis chondrocyte by activating LXRα.

Abstract
The purpose of the present study was to investigate the protective effect of esculetin (ES) in lipopolysaccharide (LPS)-induced acute lung injury (ALI) and the lung epithelial A549 cells. Mice were intragastrically administered with ES (20 and 40 mg/kg) 1 h prior to LPS challenge. ES pretreatment at doses of 20 and 40 mg/kg effectively attenuated LPS-induced lung histopathological change, myeloperoxidase or MPO activity, inflammatory cells infiltration, pulmonary wet-to-dry weight ratio, and the generation of pro-inflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in vivo and in vitro. Furthermore, we demonstrated that ES blocked the activation of NF-кB and RhoA/Rho kinase pathways in LPS-induced mice and A549 cells. The results suggested that ES exhibited protective effect on ALI and might attribute partly to the inhibition of NF-кB and RhoA/Rho kinase pathways in vivo and in vitro.

Abstract
Age-related inflammation is the predominant factor for neurodegenerative diseases like Alzheimer's disease (AD). In the present study, we examined memory performance and neuroinflammation in D-galactose (D-gal)-induced sub-acute aging model of rats. Our results demonstrated that chronic administration of D-gal (120 mg/kg) produced cognitive impairment as determined by Morris water maze (MWM) test and step-down passive avoidance test. D-gal also activated nuclear factor kappa B (NF-κB) p65/RelA by down-regulating the expression level of sirtuins 1 (SIRT1) in the hippocampus. Treatment with Salidroside (Sal, 20, 40 mg/kg) for 28 days ameliorated D-gal-induced memory deficits and inflammatory mediators including tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). Moreover, D-gal-induced activation of NF-κB signaling pathway in the brain was also inhibited by Sal via up-regulating SIRT1. These results suggest that D-gal-triggered memory impairment and inflammatory response may be associated with SIRT1/NF-κB signaling pathway, whereas treatment with Sal could positively affect these changes in hippocampus.

Abstract
Liver fibrosis, which is the pathophysiologic process of the liver due to sustained wound healing in response to chronic liver injury, will eventually progress to cirrhosis. Puerarin, a bioactive isoflavone glucoside derived from the traditional Chinese medicine pueraria, has been reported to have many anti-inflammatory and anti-fibrosis properties. However, the detailed mechanisms are not well studied yet. This study aimed to investigate the effects of puerarin on liver function and fibrosis process in mice induced by CCl4. C57BL/6J mice were intraperitoneally injected with 10% CCl4 in olive oil(2mL/kg) with or without puerarin co-administration (100 and 200mg/kg intraperitoneally once daily) for four consecutive weeks. As indicated by the ameliorative serum hepatic enzymes and the reduced histopathologic abnormalities, the data collected showed that puerarin can protect against CCl4-induced chronic liver injury. Moreover, CCl4-induced development of fibrosis, as evidenced by increasing expression of alpha smooth muscle actin(α-SMA), collagen-1, transforming growth factor (TGF)-β and connective tissue growth factor(CTGF) in liver, were suppressed by puerarin. Possible mechanisms related to these suppressive effects were realized by inhibition on NF-κB signaling pathway, reactive oxygen species(ROS) production and mitochondrial dysfunction in vivo. In addition, these protective inhibition mentioned above were driven by down-regulation of PARP-1 due to puerarin because puerarin can attenuate the PARP-1 expression in CCl4-damaged liver and PJ34, a kind of PARP-1 inhibitor, mimicked puerarin's protection. In conclusion, puerarin played a protective role in CCl4-induced liver fibrosis probably through inhibition of PARP-1 and subsequent attenuation of NF-κB, ROS production and mitochondrial dysfunction.

Abstract
Crocetin ester (CE) is the active ingredient of Crocus sativus L. stigmas and Gardenia jasminoides Ellis fruit. The main purpose of the present study was to investigate the protective effect of CE on isoproterenol (ISO)-induced acute myocardial ischemia (AMI) through Rho/ROCK/NF-κB pathway and explore its underlying mechanism. Administration of CE (25 and 50mg/kg) could significantly reduce the serum contents of pro-inflammatory cytokines including tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and interleukin-6 (IL-6). In addition, pretreatment with CE attenuated the contents of creatine kinase (CK), malondialdehyde (MDA) and the activities of lactate dehydrogenase (LDH), superoxide dismutase (SOD) in serum. Treatment with CE also improved the histopathological alteration and decreased the ST elevation. Furthermore, CE could ameliorate the cardiac expressions of Cu, Zn-superoxide dismutase (SOD1), MDA5, Rho, ROCK, p-IκB and p-NF-κBp65 in ISO-induced rats. It was assumed that CE might be a new therapeutic candidate for the treatment of AMI possibly through the inhibition of Rho/ROCK/NF-κB pathway.

The present study was designed to detect the anti-depressant effects of paeonol and the possible mechanisms in the lipopolysaccharide-induced depressive-like behavior. Open-field test(OFT), tail suspension test(TST) and forced swimming test(FST) were used to evaluate the behavioral activity. The contents of 5-hydroxytryptamine (5-HT) and norepinephrine (NE) in mice hippocampus were determined by HPLC-ECD. Serum interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α levels were evaluated by enzyme-linked immunosorbent assay (ELISA). Our results showed that LPS significantly decreased the levels of 5-HT and NE in the hippocampus. LPS also reduced open-field activity, as well as increased immobility duration in FST and TST. Paeonol administration could effectively reverse the alterations in the concentrations of 5-HT, NE and reduce the IL-6 and TNF-α levels. Moreover, paeonol effectively downregulated brain-derived neurotrophic factor (BDNF), tropomyosin-related kinase B (TrkB) and Nuclear factor-κB (NF-κB) in hippocampal. In conclusion, paeonol administration exhibited significant antidepressant-like effects in mice with LPS-induced depression.

Abstract
T helper 9 (Th9) cells, a recently recognized Th cell subset, are involved in autoimmune diseases. We aimed to investigate the role of Th9/interleukin-9 (IL-9) in the pathogenesis of hepatic fibrosis. Th9 and Th17 cells were quantified in chronic hepatitis B (CHB) patients with hepatic fibrosis, HBV-associated liver cirrhosis (LC) patients and healthy controls (HC). The percentages of Th9 and Th17 cells, concentrations of IL-9 and IL-17, as well as expression of IL-17, TNF-α, IL-6, IL-4, IL-21, TGF-β1 and IFN-γ were significantly increased in plasma of CHB and LC patients compared with those in HC. Splenic Th9 and Th17 cells, plasma concentrations and liver expression of IL-9 and IL-17A were significantly elevated in mice with hepatic fibrosis compared with controls. Neutralization of IL-9 in mice ameliorated hepatic fibrosis, attenuated the activation of hepatic stellate cells, reduced frequencies of Th9, Th17 and Th1 cells in spleen, and suppressed expression of IL-9, IL-17A, IFN-γ, TGF-β1, IL-6, IL-4 and TNF-α in plasma and liver respectively. Our data suggest a deleterious role of Th9/IL-9 in increasing hepatic fibrosis and exacerbating disease endpoints, indicating that Th9/IL9 based immunotherapy may be a promising approach for treating hepatic fibrosis.

Abstract
P2X7 receptor is a ligand gated ion channel found peripheral macrophages and microglia in the nervous system. The current study investigated the relationship between the activated P2X7 and depression for the first time. Chrysophanol (Chr) was examined for its protective effects against depression targeting P2X7. Chr (20mg/kg, 40mg/kg) and fluoxetine (20mg/kg) were intragastrically treated once daily for 7 consecutive days. Lipopolysaccharide (LPS, 0.5mg/kg) was intraperitoneally injected to develop depression model 30min after drug administration on day 7. Behavioral tests were measured 24h after LPS injection. Interleukin (IL)-6, IL-1β and tumor necrosis factor (TNF)-α levels in serum and hippocampus were measured by enzyme-linked immunosorbent assay (ELISA). The expressions of P2X7/NF-κB pathway-related proteins were assessed by western blot. The findings showed that Chr remarkably reduced the elevations of IL-6, IL-1β and TNF-α caused by LPS stimulation. The expressions of P2X7, p-IKKα, p-IKKβ, p-IκBα and p-NF-κBp65 were significantly decreased by Chr pretreatment. In addition, immobility time in tail suspension test (TST) and forced swimming test (FST) were reduced by Chr without affecting spontaneous locomotor activity in open filed test (OFT) and the preference for sucrose was also recovered in sucrose preference test (SPT) with Chr preconditioning. Thus, it is reasonable to speculate that Chr might exert antidepressant effect through inhibiting P2X7/NF-κB signaling pathway.

Abstract
The prevalence of cognitive impairment in rheumatoid arthritis (RA) patients was increasingly serious nowadays. The purpose of the current study was to explore whether salidroside (Sal) could alleviate arthritis-induced cognition deficits and examine the relationship between the impairment and Rho/ROCK/NF-κB pathway. Collagen-induced arthritis (CIA) was established by the injection of chicken type II collagen (CII), complete Freund's adjuvant (CFA) and incomplete Freund's adjuvant (IFA). Arthritic lesions of CIA rats were assessed by arthritis index score, swelling of paws and histological analysis. Cognitive deficits symptoms of CIA rats were monitored through Morris water maze test. The contents of pro-inflammatory cytokines tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β) and interleukin-6 (IL-6) in hippocampus and serum were significantly reduced with salidroside (20 mg/kg, 40 mg/kg) treatment compared with those in the CIA group. In parallel, we demonstrated that the expressions of RhoA, ROCK1, ROCK2, p-NF-κBp65, p-IκBα, p-IKKα and p-IKKβ were enhanced accompanying the investigation arthritis-induced cognition deficits, which were remarkably down-regulated by salidroside and confirmed by the results obtained from western blot and immunohistochemistry. LC-MS/MS results ascertained that Sal could enter into the blood and brain tissues to exhibit the protective effect on arthritis-induced cognitive dysfunction. Therefore, it was assumed that Sal might be a potential therapeutic candidate to treat arthritis-induced brain cognition deficits through the regulation of Rho/ROCK/NF-κB signaling.

Abstract
Tiao He Yi Wei granule (DHYW), a traditional Chinese medicine, has been used for the treatment of gastric ulcer in clinical setting. The purpose of the present study was to investigate the possible effect of DHYW and explore the underlying mechanism against ethanol-induced gastric ulcer in mice. The model of ethanol-induced gastric ulcer in mice was induced by ethanol (0.2 mL/kg). Administration of DHYW at the doses of 250, 500 mg/kg body weight prior to the ethanol ingestion could effectively protect the stomach from ulceration. The gastric lesions were significantly ameliorated in the DHYW group compared with that in the model group. Treatment with DHYW markedly decreased the levels of interleukin-6 (IL-6), IL-1β, and tumor necrosis factor-α (TNF-α). In addition, DHYW treatment elevated myeloperoxidase (MPO) level in stomach, increased superoxide dismutase (SOD) activity, and decreased malonaldehyde (MDA) content in serum and stomach compared with those in the model group. DHYW significantly inhibited NF-κB pathway expressions in the gastric mucosa ulcer group. Taken together, DHYW exerted a gastroprotective effect against gastric ulceration and the underlying mechanism might be associated with NF-κB pathway.

Abstract
The purpose of this study was to investigate the protective effects of curculigoside A (CA) on adjuvant arthritis (AA) rats and explore its possible mechanisms. AA was induced by intradermal injection of Freund's complete adjuvant (FCA). Male SD rats were treated with CA(10 and 20mg/kg) from days 18 to 24 after immunization. The levels of interleukin (IL)-6, IL-1β, tumor necrosis factor-α (TNF-α) and prostaglandin E2 (PGE2) in serum were determined by ELISA. Moreover, the levels of super oxide dismutase (SOD) and malondialdehyde (MDA) were determined using commercial kits. In particular, NLRP3 inflammasome and NF-кB pathway were detected by Western blot. As expected, CA at 10 and 20mg/kg significantly relieved the hind paw swelling and arthritis index, reduced the levels of IL-6 IL-1β, PGE2, TNF-α, MDA and increased SOD activity in serum. In addition, CA effectively down-regulated the expression of NF-кB/NLRP3 pathway. These findings showed that CA exerted beneficial effects on rheumatoid arthritis in rats.

Abstract
Background Many synthesized drugs with clinical severe side effects have been used for diabetic nephropathy (DN) treatment. Therefore, it is urgent and necessary to identify natural and safe agents to remedy DN. Timosaponin B-II (TB-II), a major steroidal saponin constituent in Anemarrhena asphodeloides Bunge, exhibits various activities, including anti-inflammatory and hypoglycemic functions. However, the anti-DN effects and potential mechanism(s) of TB-II have not been previously reported. Purpose To investigate the effect of TB-II on DN in alloxan-induced diabetic mice. Methods TB-II was isolated and purified from A. asphodeloides Bunge using macroporous adsorption resin and preparative high-performance liquid chromatography. The effect of TB-II on DN was evaluated in alloxan-induced diabetic mice using an assay kit and immunohistochemical determination in vivo. The expression of mammalian target of rapamycin (mTOR), thioredoxin-interacting protein (TXNIP), and nuclear transcription factor-κB (NF-κB) signaling pathways was also measured using Western blot analysis. Results TB-II significantly decreased the blood glucose levels and ameliorated renal histopathological injury in alloxan-induced diabetic mice. In addition, TB-II remarkably decreased the levels of renal function biochemical factors, such as kidney index, blood urea nitrogen, serum creatinine, urinary uric acid, urine creatinine, and urine protein, and it reduced lipid metabolism levels of total cholesterol and triglycerides and the levels of inflammatory cytokines interleukin-6 and tumor necrosis factor-α in alloxan-induced mice. Furthermore, TB-II inhibited the expression of mTOR, TXNIP, and NF-κB. Conclusion The results revealed that TB-II plays an important role in DN via TXNIP, mTOR, and NF-κB signaling pathways. Overall, TB-II exhibited a prominently ameliorative effect on alloxan-induced DN.

Abstract
The purpose of this study was to investigate the protective effect of PD against lipopolysaccharide (LPS)-induced acute lung injury (ALI) and explore its potential mechanism. In vivo, PD and dexamethasone were intraperitoneally administered 1h before LPS stimulation. Then, mice were sacrificed at 6h post-LPS stimulation. Neutrophil number, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and interleukin-1β (IL-1β) in bronchoalveolar lavage fluid (BALF) were determined, as well as lung wet to dry ratio (W/D) and polymorphonuclear (MPO) activity. The protein expressions of Toll like receptor 4 (TLR4), myeloid differentiating factor 88 (MyD88), IL-1R-associated kinases 1 (IRAK1), IRAK4, inhibitor of nuclear factor kappa-B kinase (IKK)α, p-IKKα, IKKβ, p-IKKβ, inhibitor of NF-κB (IκBα), p-IκBα and NF-κB in lung tissues were assessed. Besides, we detected the IL-6, IL-1β, IL-8, TNF-α levels and TLR4, MyD88, NF-κB protein expressions in LPS-induced BEAS-2B cells. Consequently, PD significantly inhibited the levels of W/D, MPO, neutrophils number, TNF-α, IL-6, IL-1β and reversed TLR4-MyD88-NF-κB signaling pathway in lung tissues. In vitro assays, PD effectively negatively mediated the inflammatory cytokines and ameliorated the high expressions of TLR4, MyD88, NF-κB caused by LPS simulation in Human bronchial epithelial BEAS-2B cells. This study indicated that PD played a protective role in LPS-induced ALI and BEAS-2B cells. The results supported further study of PD as potential candidate for acute lung injury.

Abstract
Inflammation response and oxidative stress have been reported to be involved in the pathogenesis of acute lung injury (ALI). Accordingly, anti-inflammatory treatment is proposed to be a possible efficient therapeutic strategy for ALI. The purpose of our present study was to evaluate the anti-inflammatory efficacy of trillin (Tr) on ALI induced by lipopolysaccharide (LPS) in mice and explore the underlying mechanism. BALB/c mice received Tr (50, 100 mg/kg) intraperitoneally 1 h prior to the intratracheal instillation of lipopolysaccharide (LPS) challenge. Pretreatment with Tr at the dose of 50, 100 mg/kg markedly ameliorated lung wet-to-dry weight (W/D) ratio, myeloperoxidase (MPO) activity and pulmonary histopathological conditions. In addition, the protective efficacy of Tr might be attributed to the down-regulations of neutrophil infiltration, malondialdehyde (MDA), inflammatory cytokines and the up-regulations of super-oxide dismutase (SOD), catalase(CAT), glutathione(GSH), Glutathione Peroxidase(GSH-Px) in bronchoalveolar lavage fluid (BALF). Meanwhile, our study revealed some correlations between (NF-E2-related factor 2) Nrf2/heme oxygenase (HO)-1/nuclear factor-kappa B (NF-κB) pathways and the beneficial effect of Tr, as evidenced by the significant up-regulations of HO-1 and Nrf2 protein expressions as well as the down-regulations of p-NF-κB and p-inhibitor of NF-κB (IκB) in lung tissues. Taken together, our results indicated that Tr exhibited protective effect on LPS-induced ALI by the regulations of related inflammatory events via the activations of Nrf2, HO-1 and NF-κB pathway. The current study indicated that Tr could be a potentially effective candidate medicine for the treatment of ALI.
