Objective To explore the role of MKK34 (a peptide spanning a C-terminal α-helical region in TSLP) on airway inflammation and β-catenin of airway epithelium in a HDM-induced mouse asthma.Methods 32 male BALB/c mice were randomly divided into control,MKK34,asthma and MKK34 + HDM groups.The mice in the asthma group were exposed to HDM for five consecutive days and the MKK34 + HDM group was pretreated with MKK34 1 h prior to the HDM intranasally treated.After 8 weeks' treatment,animal lung function test and pathological staining were performed to evaluate the asthma situation,IL-4,IFN-γin bronchoalveolar lavage fluid and IgE in the serum were detected,immunohistochemistry and western blot were used to assess β-catenin and p-ERK,t-ERK levels.Results Airway reactivity,IL-4 and IgE in the asthma group were significantly higher than that in the control group.Treatment with MKK34 significantly decreased airway hyperresponsiveness,IL-4 and IgE.HE staining demonstrated the chronic bronchitic inflammation in the lungs of asthma group.β-catenin in the control group was distributed evenly at the cytomembrane of epithelial cells.In the asthma group,β-catenin was disordered in epithelial cells and its expression was decreased.Treatment with MKK34 ameliorated the damage of β-catenin and chronic bronchitic inflammation.The protein levels of p-ERK1/2 increased obviously in the asthma group.The pretreated group significantly decreased the expression of p-ERK1/2.Conclusions MKK34 can ameliorate the airway inflammation and the destruction of β-catenin of airway epithelium in a HDM-induced mouse asthma.The ERK pathway may play a role in this process.

Objective To investigate the impact of 1,25(OH)2D3 on histological changes and activation of STAT3 in BLM?induced pulmonary fibrosis mice. Methods 30 male C57BL/6 mice were randomly divided into control group ,BLM group and BLM+VD group. Mice in BLM group and BLM+VD group received intratracheal injection of BLM(3 U/kg). Control group were intratracheally injected equal volume of sterile saline. From the first day after the surgery,mice in BLM+VD group received intraperitoneal injection of VD (5μg/kg·d). After 21 days, H&E and Masson′s trichrome staining were carried out. Aschroft score were used to evaluate histological changes in lungs. IL?6,IL?4 and INF?γin BALF were assessed by Elisa. p?STAT3,α?SMA and Collagen I were detected by western blot (WB) and immunohistochemistry. Results Fibrosis score and level of α?SMA,Collagen I in BLM group were significantly higher than that in control group (P < 0.05). However ,treatment with VD effectively at?tenuated fibrosis (P<0.05). IL?6 and IL?4 increased while INF?γwas decreased in BALF of BLM group (P<0.05). VD could ameliorate these changes. Upregulation and neuclear translocation of p?STAT3 were observed in BLM group,while VD intervention could inhibit phosphorylation of STAT3. Conclusions VD attenuate BLM?induced pulmonary fibrosis and regulate inflammatory cytokines probably by blocking STAT3 activation.

Objective:To preliminarily study the effect of Louqin Zhisou decoctions with the mechanism of clearing heat and resol-ving phlegm on the blood level of neutrophil elastase ( NE) in the rat model of acute exacerbation of chronic obstructive pulmonary dis-ease ( AECOPD) . Methods:The rat model of AECOPD was established by passive cigarette smoking, intratracheal instillation of li-popolysacchricle ( LPY) and intranasal instillation of staphylococcus aureus. Totally 60 AECOPD rats were randomly divided into 3 groups, the model control group (n=20), ambrohexel group (n=20), and Louqin Zhisou decoctions group (n=20). NE was detec-ted by ELISA. Results:Compared with that before the treatment, NE in ambrohexel group and Louqin Zhisou decoctions group was de-creased significantly(P<0. 01). Conclusion:Clearing heat and resolving phlegm method probably can decrease NE by reducing air-way mucus hypersecretion and obstruction in AECOPD rats.

OBJECTIVETo study the signaling pathways associated with lipopolysaccharide (LPS)-induced inflammation in islet micro-endothelial cells (IMECs) and the mechanism of pravastatin intervention.

METHODSIMECs exposed to LPS, SB203580, pravastatin, or SB203580+pravastatin were examined for cell apoptosis with Hoechst staining and flow cytometry and for expression levels of total-p38, photophosphorylation-p38 (p-p38) and iNOS with Western blotting.

RESULTSThe apoptosis rate and expression levels of total-p38, p-p38, iNOS in IMECs all increased after LPS exposure. Pravastatin, SB203580, and their combination significantly attenuated LPS-induced enhancement of cell apoptosis and total-p38, p-p38, and iNOS expressions in IMECs.

CONCLUSIONLPS-induced inflammatory toxicity in IMECs is associated with the activation of P38MAPK and iNOS/NO signaling pathways. Pravastatin can inhibit these pathways and suppress the apoptosis and necrosis of IMECs to relieve the cell inflammatory injuries.

Pannexin-1 (Panx1) forms nonselective large channel in cell plasma membrane and has been shown to be associated with NLRP3 inflammasome activation, ATP release and phagocytes recruitment. In the current study, by manipulation of Panx1 expression in human myeloid cells and application of Panx1 deficient mice, we failed to find a correlation between Panx1 and NLRP3 inflammasome activation, although an interaction between these two proteins was evident. However, in thioglycollate induced peritonitis, Panx1 deficient mice showed much more phagocytes infiltration. Further analyses showed that mice deficient for Panx1 exhibited enlarged F4/80(low)Gr1(-)Ly6C(-)cell population in the peritonea. Our study thus reveals an important role for Panx1 in regulation of peritoneal cell population and peritonitis development.
