What Moved into the Lung?An Unusual Case of Foreign Body Migration

引用

Chinese Medical Sciences Journal 2013年第4期28卷 248-249页

作者： Yan-ting Wang Xiao-dong Yang shao-hua liu Yan-hua huang Department of Respiratory Medicine West China Hospital of Sichuan University

FOREIGN body migration into the lung is a rare complication that can cause various symptoms. In adults, however, foreign body deposited in the luna can be tolerated and remain undetected fora long time. Delayed diagnosis and subsequent delayed treatment is usually associated with atypical complications. In this article, we describe a case of foreign body migration into the tracheobronchial tree. After a long time delay diagnosis, the foreign body was ultimately removed by operation.

Chinese Medical Sciences Journal 2007年第3期22卷 169-176页

作者： shao-hua liu Xin-rong Xu Ke Ma Bing Xu Intensive Care Unit the First Affiliated Hospital of Nanjing Medicial University Nanjing 210029

Objective To observe the protection of carbon monoxide （CO） inhalation on lipopolysaccharide （LPS）-induced rat multiple organ injury. Methods Sprague-Dawley rats with multiple organ injury induced by 5 mg/kg LPS intravenous injection were exposed to room air or 2.5 × 10 ^-4 （V/V） CO for 3 hours. The lung and intestine tissues of rats were harvested to measure the expression of heme oxygenase-1 （ HO-1 ） with reverse transcription-polymerase chain reaction, the levels of pulmonary tumor necrosis factor-or （ TNF-α）, interleukin-6 （ IL-6）, and intestinal platelet activator factor （ PAF）, intercellular adhesion molecule-1 （ICAM-1） with enzyme-linked immunosorbent assay, the content of maleic dialdehyde （MDA） and the activity of myeloperoxidase （MPO） with chemical method, the cell apoptosis rate with flow cytometry, and the pathological changes with light microscope. Results CO inhalation obviously up-regulated the expression of HO-1 in lung （5.43 ± 0. 92） and intestine （6. 29 ± 1.56） in LPS ＋ CO group compared with （ 3.08 ± 0. 82） and （ 3.97 ± 1.16 ） in LPS group （ both P 〈 0. 05 ）. The levels of TNF-ot, IL-6 in lung and PAF, ICAM-1 in intestine ofLPS ＋ CO group were 0. 91 ±0. 25,0. 64 ±0.05, 1. 19 ± 0. 52, and 1.83 ±0. 35 pg/mg, respectively, significantly lower than the corresponding values in LPS group （ 1.48 ± 0. 23, 1.16 ± 0. 26, 1.84 ± 0. 73, and 3.48 ± 0. 36 pg/mg, all P 〈 0. 05 ）. The levels of MDA, MPO, and cell apoptosis rate in lung and intestine of LPS ＋ CO group were 1.02 ± 0. 23 nmol/mg, 1.74 ± 0. 17 nmol/mg, 7.18 ± 1.62 U/mg, 6. 30 ±0. 97 U/mg, 1.60% ±0. 34%, and 30. 56% ±6. 33%, respectively, significantly lower than the corresponding values in LPS group （ 1.27 ± 0. 33 nmol/mg, 2. 75 ± 0. 39 nmol/mg, 8. 16 ± 1.49 U/mg, 7. 72 ± 1.07 U/mg, 3.18% ±0. 51%, and 41.52% -＋3.36%, all P 〈0.05）. In addition, injury of lung and intestine induced by LPS was attenuated at presence of CO inhalation. Conclusion CO inhalation protects rat lung and intestine from LP

In this Letter, an autofocusing method in optical scanning holography (OSH) system is proposed. By introducing Lissajous scanning into multiple signal classification (MUSIC) method in time-reversal (TR) OSH, the axial locations of the targets can be retrieved with better resolution and the peak prominence increases from 0.21 to 0.34. The feasibility of this method is confirmed by simulation as well as experiment.

作者： shao-hua liu Wei Peng Yan-Yan Qu Dan Xu Hong-Yue Li Dun-Lun Song Hong-Xia Duan Xin-Ling Yang Department of Applied Chemistry College of ScienceChina Agricultural University Department of Entomology College of Agriculture and BiotechnologyChina Agricultural University

A series of novel neonicotinoid analogues were designed and synthesized by introducing a hydrazide group into clothianidin. Their structures were confirmed by IR, 1H NMR, and HRMS （ESI）. Preliminary bioassay showed that some compounds, Sb and Sg, exhibited good activity against soybean aphids （Aphis glycines） at 100 mg L ^-1. In addition, molecular docking with receptor was carried out to explain their different activity from clothianidin.

AIM To investigate the distribution and function of interstitialcells of Cajal(ICCs) and platelet-derived growth factor receptor-α positive(PDGFRα+) cells in the proximal and distal *** The comparison of colonic transit in the proximal and distal ends was performed by colonic migrating motor complexes(CMMCs). The tension of the colonic smooth muscle was examined by smooth muscle spontaneous contractile experiments with both ends of the smooth muscle strip tied with a silk thread. Intracellular recordings were used to assess electrical field stimulation(EFS)-induced inhibitory junction potentials(IJP) on the colonic smooth muscle. Western blot analysis was used to examine the expression levels of ICCs and PDGFRα in the colonic smooth *** Treatment with NG-nitro-L-arginine methyl ester hydrochloride(L-NAME) significantly increased the CMMC frequency and spontaneous contractions, especially in the proximal colon, while treatment with MRS2500 increased only distal CMMC activity and smooth muscle contractions. Both CMMCs and spontaneous contractions were markedly inhibited by NPPB, especially in the proximal colon. Accordingly, CyPPA sharply inhibited the distal contraction of both CMMCs and spontaneous contractions. Additionally, the amplitude of stimulationinduced nitric oxide(NO)/ICC-dependent slow IJPs(sIJPs) by intracellular recordings from the smooth muscles in the proximal colon was larger than that in the distal colon, while the amplitude of electric field stimulationinduced purinergic/PDGFRα-dependent fast IJPs(fIJPs) in the distal colon was larger than that in the proximal colon. Consistently, protein expression levels of c-Kit and anoctamin-1(ANO1) in the proximal colon were much higher, while protein expression levels of PDGFRα and small conductance calcium-activated potassium channel 3(SK3) in the distal colon were much *** The ICCs are mainly distributed in the proximal colon and there are more PDGFRα+ cells are in the dis
