Effect of antiallergic herbal agents on chloride channel-3 and immune microenvironment in nasal mucosal epithelia of allergic rhinitis rabbits

引用

Chinese Medical Journal 2010年第8期123卷 1034-1038页

作者： wang Li-feng XU Li-juan guo feng-hua wang Li-na SHEN Xiao-hong Medical College of Nankai University Tianjin 300071 China

Background Allergic rhinitis （AR） is a Th2 dominant cytokine response. Chloride channel-3 （CIC-3） plays an important role in nasal mucosal edema and inflammatory pathologic changes in AR. Antiallergic herbal agents （AHA） are antiallergic herbal products. In the previous study, we have demonstrated that AHA clearly inhibited allergic medium and relieved allergic reaction of AR. The aim of this study was to evaluate the function of CIC-3 and discuss the possible therapeutic effects of AHA on immune microenvironment in AR. Methods AHA were produced and used to treat AR. An animal model of an AR rabbit was established by ovalbumin （OVA）. The rhinitis rabbits were randomly divided into three groups： AHA treated group （AHATG）, model group （MG） and healthy control group （HCG）. The expressions of CIC-3 protein were examined by immunohistochemical method. The mucosal epithelial cells of all the rabbit groups were primarily cultured with tissue culture method in vitro with or without rhlL-4 or rhlL-2. Furthermore, the expressions of CIC-3 mRNA were detected by real-time PCR. The levels of monocyte chemotactic factor-1 （MCP-1） and vascular cell adhesion molecule-1 （VCAM-1） protein in culture supernatants were measured by ELISA. Results The expressions of CIC-3 mRNA increased more in mucosal epithelial cells of MG than those in AHATG and HCG （P 〈0.01）. The levels of CIC-3 mRNA, MCP-1 and VCAM-1 protein in culture supernatants of MG were significantly higher than those in the other two groups （P 〈0.01）. Those were significantly increased in MG untreated 12 hours later than those in other two groups （P 〈0.01）. The expressions of CIC-3 mRNA, MCP-1 and VCAM-1 protein in culture supernatants of MG and HCG treated with rhlL-4 were significantly higher than those in the AHATG treated with rhlL-4 （P 〈0.01）. The levels of CIC-3 mRNA, MCP-1 and VCAM-1 protein in culture supernatants of all groups treated with rhlL-2 showed no significant changes （P 〉0.05）. Conclusions AHA can inhibit the

Mean First-Passage Time of an Asymmetric Kinetic Model Driven by Two Different Kinds of Colored Noises

引用

Communications in Theoretical Physics 2008年第3期49卷 689-695页

作者： LI Dong-Xi XU Wei guo Yong-feng wang Liang Department of Applied Mathematics Northwestern Polytechnical University Xi＇an 710072 China

The mean first-passage time （MFPT） of an asymmetric bistable system between multiplicative non-Gaussian noise and additive Gaussian white noise with nonzero cross-correlation time is investigated. Firstly, the non-Markov process is reduced to the Markov process through a path-integral approach; Secondly, the approximate Fokker Planck equation is obtained by applying the unified colored noise approximation and *** Theorem. The steady-state probability distribution （SPD） is also obtained. The basal functional analysis and simplification are employed to obtain the approximate expressions of MFPT T^±. The effects of the asymmetry parameter β, the non-Gaussian parameter （measures deviation from Gaussian character） r, the noise correlation times τ and τ2, the coupling coefficient A, the intensities D and a of noise on the MFPT are discussed. It is found that the asymmetry parameter β, the non-Gaussian parameter r and the coupling coefficient A can induce phase transition. Moreover, the main findings are that the effect of self-existent parameters （D, α, and τ） of noise and cross-correlation parameters （A, 7-2） between noises on MFPT T^± is different.

Loss of p120 catenin aggravates alveolar edema of ventilation induced lung injury

引用

Chinese Medical Journal 2013年第15期126卷 2918-2922页

Background p120 catenin （p120ctn） is an adheren junction protein that regulates barrier function, but its role has not been explored in alveolar edema induced by ventilation. We measured stretch-induced cell gap formation in MLE 12 cells due to the loss of p120. We hypothesized that alveolar permeability was increased by high tung inflation associated with alveolar epithelia cell tight junctions being destroyed, which resulted from the loss of p120. Methods Cultured MLE12 cells were subjected to being stretched or un-stretched （control） and some cells were pretreated with pp2 （c-src inhibitor）. After the end of stretching for 0, 1, 2, and 4 hours, the cells were lysed, and p120 expression and c-src activation was determined by Western blotting analysis. In vivo, SD rats were taken to different tidal volumes （Vt 7 ml/kg or 40 ml/kg, PEEP=0, respiratory rate 30-40 betas/min） for 0, 1, 2, and 4 hour and some were pretreated with pp2, and alveolar edema was calculated. Rerults It was found that p120 expression was reduced and c-src activation increased in a time-dependent and strain- dependent manner due to cyclic-stretch of the alveolar epithelial cells. These changes could be reversed by inhibition of c-src. We obtained similar changes in rats when they were subjected to large tidal volumes and the alveolar edema increased more than in rats in the low Vt group. Pretreated the rats with inhibition of c-src had less pulmonary edema induced by the high tidal volume ventilation. Conclusions Cyclic stretch MLE 12 cells induced the loss of p120 and may be the same reason by high tidal volume ventilation in rats can aggravate alveolar edema. Maintenance of p120 expression may be a novel therapeutic strategy for the prevention and treatment of ventilation induced lung injury （VILI）.

Exact Box-Constrained Economic Operating Region for Power Grids Considering Renewable Energy Sources

Journal of Modern Power Systems and Clean Energy 2024年第2期12卷 514-523页

作者： Huating Xu Bin feng Chutong wang Chuangxin guo Jian Qiu Mingyang Sun College of Electrical Engineering Zhejiang UniversityHangzhou 310027China Department of Control Science and Engineering Zhejiang UniversityHangzhou 310027China

The growing integration of renewable energy sources manifests as an effective strategy for reducing carbon emissions. This paper strives to efficiently approximate the set of optimal scheduling plans(OSPs) to enhance the performance of the steady-state adaptive cruise method(SACM) of power grid, improving the ability of dealing with operational uncertainties. Initially, we provide a mathematical definition of the exact boxconstrained economic operating region(EBC-EOR) for the power grid and its dispatchable components. Following this, we introduce an EBC-EOR formulation algorithm and the corresponding bi-level optimization models designed to explore the economic operating boundaries. In addition, we propose an enhanced big-M method to expedite the computation of the EBCEOR. Finally, the effectiveness of the EBC-EOR formulation, its economic attributes, correlation with the scheduling plan underpinned by model predictive control, and the significant improvement in computational efficiency(over twelvefold) are verified through case studies conducted on two test systems..
