| 1 | Qingfei Xiaoyan Wan,a traditional Chinese medicine formula, ameliorates Pseudomonas aeruginosa–induced acute lung inflammation by regulation of PI3K/AKT and Ras/MAPK pathways显示文摘Gram-negative pathogen–induced nosocomial infections and resistance are a most serious menace to global public health. Qingfei Xiaoyan Wan(QF), a traditional Chinese medicine(TCM)formula, has been used clinically in China for the treatment of upper respiratory tract infections, acute or chronic bronchitis and pulmonary infection. In this study, the effects of QF on Pseudomonas aeruginosa–induced acute pneumonia in mice were evaluated. The mechanisms by which four typical antiinflammatory ingredients from QF, arctigenin(ATG), cholic acid(CLA), chlorogenic acid(CGA) and sinapic acid(SPA), regulate anti-inflammatory signaling pathways and related targets were investigated using molecular biology and molecular docking techniques. The results showed that pretreatment with QF significantly inhibits the release of cytokines(TNF-α and IL-6) and chemokines(IL-8 and RANTES),reduces leukocytes recruitment into inflamed tissues and ameliorates pulmonary edema and necrosis. In addition, ATG was identified as the primary anti-inflammatory agent with action on the PI3K/AKT and Ras/MAPK pathways. CLA and CGA enhanced the actions of ATG and exhibited synergistic NF-κB inactivation effects possibly via the Ras/MAPK signaling pathway. Moreover, CLA is speculated to target FGFR and MEK firstly. Overall, QF regulated the PI3K/AKT and Ras/MAPK pathways to inhibit pathogenic bacterial infections effectively. | Yuanyuan Hou Yan Nie Binfeng Cheng Jin Tao Xiaoyao Ma Min Jiang Jie Gao Gang Bai | 2016 | Acta Pharmaceutica Sinica B2016，6，3： | 17 |
| 2 | Studies on exposure status of inhabitants to water-arsenic valence states in areas with endemic arsenism in the Datong basin in Shanxi显示文摘This study aimed to describe the distribution of water-arsenic(As)valence states and its relationship to areas with endemic arsenism in the Datong basin.Drinking water samples of patients with endemic arsenism and a control group were examined using hydride generation atomic fluorescence spectrometry(HG-AFS).We analyzed the data using SPSS10.0 for Windows.The As(III)/As ratio was 52.1%in the water sample,exceeding the national standard of 0.05 mg/L.The As(III)/As ratio significantly varied among the different stages in the disease-state groups,and with the control group(χ^(2)=22.4,P<0.01).The As(III)/As(V)ratio significantly varied in the four groups(χ^(2)=26.19,P<0.01),with a tendency to increase along with the seriousness of the disease state.The most common type of drinking water arsenic valence state was As(III)in the endemic diseaseareas.Endemic arsenism was positively correlated with As(III).This led us to conclude that the fraction of each water-arsenic valence state should be studied when determining the arsenic content of drinking water. | LI Jun CHENG Xiaotian WANG Zhenghui WEN Xinping HAN Lingling SANG Zhiping ZHANG Jie DUAN Hushun LIANG Binfeng GAO Jianguo | 2007 | Frontiers of Medicine2007，1，2： | 0 |
