目的探讨降气化痰推拿法对慢性哮喘幼鼠气道重塑的治疗作用及潜在机制。方法将50只SPF级雌性BALB/c小鼠随机分为对照组(A组)、模型组(B组)、推拿组(C组)、地塞米松组(D组)、推拿+地塞米松组(E组),每组10只。其中除A组外,其余小鼠均制备哮喘模型。第16天开始,C、D、E组进行相应推拿、地塞米松、推拿+地塞米松治疗,B组注射等量生理盐水;第22天开始,各组连续激发7 d。比较各组的肺功能、血清白介素4(interleukin 4,IL-4)水平、肺组织病理改变以及肺组织转化生长因子β1(TGF-β1)、Smad3 mRNA和蛋白表达水平。结果肺能功方面,与A组相比,各组给药后的气道狭窄指数明显升高、肺顺应性下降,且C、D、E组的气道狭窄指数低于B组,肺顺应性高于B组。在高浓度乙酰胆碱(6.250 g·L^(-1),12.500 g·L^(-1),25.000 g·L^(-1))给药时,E组的气道狭窄指数明显低于C、D组,且C组低于D组,C组肺顺应性低于D组(P<0.05);炎性水平方面,与A组相比,各组IL-4水平、炎症细胞浸润程度均升高,且C、D、E组均低于B组,E组低于C、D组,差异具有统计学意义(P<0.05);HE染色结果显示,A组肺组织无明显炎性改变,B组炎性细胞浸润严重,C组、D组、E组轻微炎症浸润,且E组浸润程度低于C、D组;与A组相比,各组气道壁厚度和气道平滑肌厚度升高,且、D、E组均低于B组,E组低于C、D组;与A组相比,各组TGF-1β、Smad3 mRNA和蛋白水平均升高,且C、D、E组均低于B组,E组低于C、D组,差异具有统计学意义(P<0.05)。结论降气化痰推拿法能够有效改善慢性哮喘幼鼠的气道重塑,降低炎性反应水平,减轻炎性浸润,其机制可能与下调TGF-β1/Smad3通路表达相关。

The realistic security of quantum key distribution(QKD) systems is currently a hot research topic in the field of quantum communications. There are always defects in practical devices, and eavesdroppers can make use of the security risk points of various devices to obtain key information. To date, current types of security analysis tend to analyze each security risk point individually, thereby posing great challenges for the overall security evaluation of QKD systems. In this paper, for the first time, we employ machine learning algorithms to identify the defects of different devices and certain attacks in real time, with an accuracy of 98%. It provides a novel solution for the practical security evaluation of QKD systems, thereby addressing the bottleneck problem of multiple risk points being difficult to address simultaneously in QKD systems,thus paving the way for the future large-scale application of quantum communication networks.

Rose （Rosa chinexis Jacq）, a traditional Chinese ornamental flower, is widely planted for landscaping in China. Diseases, together with their typical symptoms on R. chinensis in China, are presented in this review. Ten fungal, one bacterial, one viral and one physiological disease are noted in this study respec- tively. Two newly recorded diseases, rose leaf spot caused by ChaetomeUa raphigera and rose leaf blotch caused by Pestalotiopsis clavispom, are also described and illustrated. With the warming climate, the geographic distribution of rose diseases may expand and the losses cause by rose diseases are becoming more serious. Therefore, we must strengthen researches on host-pathogen-changing climate and pay more attentions on adapted management measures as well.

2010 3rd International Conference on Computer and Electrical Engineering(ICCEE 2010)

作者： jingyang xu Dengfeng KE Lei JIA Digital Media Content Technology Research Center Institute of AutomationChinese Academy of Sciences

In conventional speech recognition system, only a plain text is presented as the final result, and all acoustic information of speech are cutoff. The aim of this publication is to add intonation information to traditional output of speech recognition engine, which is believed to reflect the emotion and intention of speaker. In this paper, we propose a robust approach to classify several kinds of intonations, e.g. declara-tive, interrogative, exclamatory, etc. Since it is still an open question on how to describe intonations, different kinds of features are investigated here to choose the most effective features for intonations classification. Support Vector Machine (SVM) is used as the classifier to perform the task of feature selection and combination. In our experiment, we address the speech recognition based methods, and use recognized results replace the transcribed text. Our goal is to simulate intonation classification in the real speech recognition. The speech materials used in this experiment were well designed includes three intonations, total about 4700 sentences. Experimental results show that our system can achieves the accuracy of (84.13%) for the task of three types of Chinese intonation classification.
