Effect of Yiqi Bufei Recipe （益气补肺方） on Patients with Pulmonary Incompetence after Pneumonectomy

Chinese Journal of Integrative Medicine 2011年第12期17卷 898-902页

作者： YANG Yong SHEN You-kui ZHOU Xing-ming FU Xiao-qing MAO Wei-min DONG Li-wen WANG Jun cheng gen-miao Hangzhou Hospital of Traditional Chinese Medicine Hangzhou （310007） China Zhejiang Provincial Hospital of Oncology Hangzhou （310022） China

Objective： To study the effect of Yiqi Bufei Recipe （益气补肺方, YBR） on surgical tolerability, pulmonary compensatory function and post-operation rehabilitation in patients with pulmonary incompetence （PI） after pneumonectomy. Methods： YBR intervention was applied to 60 patients with PI after pneumonectomy （as test group）, the pulmonary and cardiac functions changes before and after operation, occurrence of postoperative complications, mortality, and the number of hospitalization days and intensive care unit （ICU） confinement period were observed. Meantime, for the negative and positive controls, the same parameters were observed comparatively in 60 patients with normal lung function, and in 60 patients with PI undergoing a similar operation but untreated with Chinese herbs. Results： Lung function in the test group showed insignificant change before and after operation （P〉0.05）, while significant decrease was seen in the two control groups （P〈0.05）. Furthermore, the incidences of post-operation complications and mortality as well as the number of hospitalization days and the ICU confinement period in the test group were significantly lower than those in the positive control group respectively （P〈0.05）. Conclusion： YBR could relieve lung injury after pneumonectomy, improve surgical tolerability, reduce the length of postoperative hospitalization days and ICU confinement period, and lower the incidence of postoperative complications and mortality in patients with PI after pneumonectomy.

湖泊水质直接影响周边生态、人类健康和经济,而现代工业、城市化带来的压力使得湖泊面临着严峻挑战,需要深入了解变化、寻找污染源,并采取有效措施维护生态健康和人民生活水质安全。因此,基于三维荧光(3DEEMs)和平行因子(PARAFAC)方法,对2022年长荡湖及其周边面源的水质溶解性有机物(DOM)的荧光光谱进行分析,探讨了长荡湖DOM的荧光组分来源及时空分布,同时对比周边面源荧光与湖体荧光的相似性。结果表明,长荡湖水体的溶解有机质(DOM)荧光主要由两类荧光组分构成:类蛋白荧光组分(C1)和类腐殖质组分(C2、C3、C4)。这些组分与周边印染、生活排放以及水产养殖等源头的荧光组分相似度较高。长荡湖在不同水期各类荧光分布存在差异,特别是丰水期,荧光强度主要集中于下游出湖口。长荡湖荧光特征参数FI的值为(1.68~1.75),BIX的值在(0.92~0.93),HIX的值在(0.56~0.7),表明长荡湖DOM的增量以内源为主。综合分析显示,长荡湖的有机质主要来自水生动植物和藻类的腐解等内源增量。冗余分析结果表明,与湖体DOM相关性较大的环境因子主要包括Chl-a和COD。本研究不仅对解决当地生态环境问题具有积极作用,同时也为其他湖泊生态系统的研究提供了有价值的实践经验。

CPA-VoD： Cloud and Peer-Assisted Video on Demand System for Mobile Devices

引用

Journal of Computer Science & Technology 2016年第6期31卷 1087-1095页

作者： Lei-gen cheng Laizhong Cui Yong Jiang Graduate School at Shenzhen Tsinghua University Shenzhen 518055 China College of Computer Science and Software Engineering Shenzhen University Shenzhen 518060 China

With the rapid development of WiFi and 3G/4G, people tend to view videos on mobile devices. These devices are ubiquitous but have small memory to cache videos. As a result, in contrast to traditional computers, these devices aggravate the network pressure of content providers. Previous studies use CDN to solve this problem. But its static leasing mechanism in which the rental space cannot be dynamically adjusted makes the operational cost soar and incompatible with the dynamically video delivery. In our study, based on a thorough analysis of user behavior from Tencent Video, a popular Chinese on-line video share platform, we identify two key user behaviors. Firstly, lots of users in the same region tend to watch the same video. Secondly, the popularity distribution of videos conforms with the Pareto principle, i.e., the top 20% popular videos own 80% of all video traffic. To turn these observations into silver bullet, we propose and implement a novel cloud- and peer-assisted video on demand system （CPA-VoD）. In the system, we group users in the same region as a peer swarm, and in the same peer swarm, users can provide videos to other users by sharing their cached videos. Besides, we cache the 10% most popular videos in cloud servers to further alleviate the network pressure. We choose cloud servers to cache videos because the rental space can be dynamically adjusted. According to the evaluation on a real dataset from Tencent Video, CPA-VoD alleviates the network pressure and the operation cost excellently, while only 20.9% traffic is serviced by the content provider.

Developmental characteristics and response to iron toxicity of root border cells in rice seedlings

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2008年第3期9卷 261-264页

作者： cheng-hua XING Mei-hong ZHU miao-zhen CAI Peng LIU gen-di XU Shao-hui WU Bioengineering Institute Jinhua College of Profession and Technology Jinhua 321007 China College of Chemistry and Life Sciences Zhejiang Normal University Jinhua 321004 China

To investigate the Fe^2＋ effects on root tips in rice plant, experiments were carried out using border cells in vitro. The border cells were pre-planted in aeroponic culture and detached from root tips. Most border cells have a long elliptical shape. The number and the viability of border cells in situ reached the maxima of 1600 and 97.5%, respectively, at 20---25 mm root length. This mortality was more pronounced at the first 1-12 h exposure to 250 mg/L Fe^2＋ than at the last 12-36 h. After 36 h, the cell viability exposed to 250 mg/L Fe^2＋ decreased to nought, whereas it was 46.5% at 0 mg/L Fe^2＋. Increased Fe^2＋ dosage stimulated the death of detached border cells from rice cultivars. After 4 h Fe^2＋ treatment, the cell viabilities were _〉80% at 0 and 50 mg/L Fe^2＋ treatment and were 〈62% at 150, 250 and 350 mg/L Fe^2＋ treatment; The viability of border cells decreased by 10% when the Fe^2＋ concentration increased by 100 mg/L. After 24 h Fe^2＋ treatment, the viabilities of border cells at all the Fe^2＋ levels were 〈65%; The viability of border cells decreased by 20% when the Fee＋ concentration increased by 100 mg/L. The decreased viabilities of border cells indicated that Fe^2＋ dosage and treatment time would cause deadly effect on the border cells. The increased cell death could protect the root tips from toxic harm. Therefore, it may protect root from the damage caused by harmful iron toxicity.

Carbon nanotubes with larger inner diameter were synthesized by the chemical vapor deposition of carbon monoxide (CO) on iron catalyst using H2S as promoting agent. It is found that the structure and morphology of carbon nanotubes can be tailored, to some degree, by varying the experimental conditions such as precursor components and process parameters. The results show that the presence of H2S may play key role for growing Y-branched carbon nanotubes. The products were characterized by SEM, TEM, and Raman spectroscopy, respectively. Furthermore, the obtained carbon nanotubes were explored as electrode materials for supercapacitor.
