1评估大气细颗粒物暴露引起的全球疾病负担的一个综合风险函数显示文摘[背景]评估由于环境空气中细颗粒物(PM2.5)长期暴露引起的疾病负担,需要了解相对风险度(RR)函数的图形和幅度。然而,在世界上很多观察到高PM2.5环境浓度的地方,都缺乏足够的直接证据确定死亡RR函数的图形。[目的]建立可用于全球PM2.5暴露范围内成人死因的RR函数:缺血性心脏病(IHD)、脑血管疾病(脑卒中)、慢性阻塞性肺病(COPD)和肺癌(LC)。建立急性下呼吸道感染(ALRI)发病的RR函数,用于估算〈5岁的儿童中死亡率和健康生活损失年数。[方法]通过整合现有的来自于环境空气污染(AAP)、二手烟草烟雾、家用固体烹饪用燃料和主动吸烟(AS)等研究的RR信息,拟合综合暴露-反应(IER)模型。采用颗粒物质的吸入剂量,通过转化AS暴露来估计全年PM2.5的暴露当量。在估算全球环境PM2.5浓度的基础上,得出各国的人群归因分数(PAFs)。[结果]与以往负担评估中使用的其他7种模型相比,IER模型是一种优越的RR预测方法。在不同国家中,归因于AAP暴露的PAF百分数各不相同,分别为:IHD,2~41;脑卒中,1~43;COPD,〈1~21;LC,〈1~25;ALRI,〈1~38。[结论]我们建立了一种以细颗粒物为基础的RR模型,它通过整合来自不同类型的燃烧所产生颗粒物排放的RR信息,涵盖全球范围的暴露。当获得新的RR信息时,可以对这个模型进行更新。Richard T.Burnett C.Arden Pope III Majid Ezzati Casey Olives Stephen S.Lim Sumi Mehta Hwashin H.Shin Gitanjali Singh Bryan Hubbell Michael Brauer H.Ross Anderson Kirk R.Smith John R.Balmes Nigel G.Bruce Haidong Kan Francine Laden Annette Prüss-Ustün Michelle C.Turner Susan M.Gapstur W.Ryan Diver Aaron Cohen 何蓉 张伊人 金泰廙 2014环境与职业医学2014,31,11:80
2基于IMRT时代的第八版AJCC/UICC鼻咽癌临床分期建议显示文摘目的准确的分期系统对癌症的治疗至关重要。随着癌症分期和治疗方法的演变,需要不断评价分期的适用性和改进性。方法基于第7版AJCC/UICC分期回顾性分析香港和中国大陆2个肿瘤中心收治的1609例接受调强放射治疗的首诊无转移鼻咽癌患者临床资料,所有患者治疗前均行核磁共振分期评估。结果无其他T3、T4期解剖结构受侵患者中,伴有咀嚼肌间隙(翼内肌和/或翼外肌)侵犯、椎前肌侵犯及咽旁间隙侵犯的三组患者之间0s相近。伴广泛软组织(上述侵犯结构以外的软组织)受侵患者OS与伴有颅内侵犯或颅神经侵犯相似。仅2%患者锁骨上窝以上淋巴结转移者直径〉6cm,其0s率与下颈淋巴结转移者类似。用下颈(环状软骨尾侧缘水平以下)代替锁骨上窝并不影响N分期之间的风险差异性。采用推荐的T、N分期,T。N。、T。N,期0s相近。结论经AJCC/UICC分期筹备委员会审阅后,建议第8版分期应将翼内肌/翼外肌从T。降到T:期,增加椎前肌为L期,用下颈取代锁骨上窝,将淋巴结最大直径〉6cm合并归为N,期,将T。、N,期统一归为Ⅳ。期。这些改变不仅使得相邻分期间风险差异性更好,而且使得临床实践性与全球适用性之间达到最佳平衡。潘建基 Wai Tong Ng 宗井凤 Lucy L.K.Chan Brian O' Sullivan 林少俊 Henry C.K.Sze 陈韵彬 Horace C.W.Choi 郭巧娟 Wai Kuen Kan 肖友平 Xu Wei Quynh Thu Le Christine M.Glastonbury A.Dimtrios Colevas Randal S.Weber Jatin P.Shah Anne W.M.Lee 2016中华放射肿瘤学杂志2016,25,3:65
3Clinicopathological and prognostic analysis of 429 patients with intrahepatic cholangiocarcinoma显示文摘AIM:To understand the clinicopathological characteristics and treatment selections and improve survival and provide valuable information for patients with intrahepatic cholangiocarcinoma(ICC). METHODS:We retrospectively evaluated 5311 liver cancer patients who received resection between October 1999 and December 2003.Of these,429(8.1%)patients were diagnosed with ICC,and their clinicopathological, surgical,and survival characteristics were analyzed. RESULTS:Upper abdominal discomfort or pain(65.0%), no symptoms(12.1%),and hypodynamia(8.2%)were the major causes for medical attention.Laboratory tests showed 198(46.4%)patients were HBsAg positive, 90(21.3%)hadα-fetoprotein>20μg/L,50(11.9%) carcinoembryonic antigen>10μg/L,and 242(57.5%) carbohydrate antigen 19-9(CA19-9)>37 U/mL.Survival data was available for 329(76.7%)patients and their mean survival time was 12.4 mo.The overall survival of the patients with R0,R1 resection and punching exploration were 18.3,6.6 and 5.6 mo,respectively. Additionally,CA19-9>37 U/mL was associated with lymph node metastases,but inversely associated withcirrhosis.Multivariate analysis indicated that radical resection,lymph node metastases,macroscopic tumor thrombi and size,and CA19-9 were associated with prognosis. CONCLUSION:Surgical radical resection is still the most effective means to cure ICC.Certain laboratory tests(such as CA19-9)can effectively predict the survival of the patients with ICC.Wei-Feng Shen Wei Zhong Feng Xu Tong Kan Li Geng Feng Xie Cheng-Jun Sui Jia-Mei Yang 2009World Journal of Gastroenterology2009,15,47:39

5Major Function Oriented Zone: New Method of Spatial Regulation for Reshaping Regional Development Pattern in China显示文摘Newest planning methods implemented by Chinese government are promoting a coordinated regional development and shaping an orderly spatial structure by applying the regulation of territorial function. This article analyzes the problems of spatial planning and regional strategy caused by the wrongly-set primary goal of economic development; it states that the three-fold objective of competitiveness, sustainability, and welfare fairness shall be the principal for China to implement the spatial regulation in the new era; it discusses about theoretical thoughts and technology framework of conducting the ′Major Function Oriented Zone′ based on their different major functions that each region plays in urbanization and industrialization, ecological constructions, grain productions, and protection of natural and cultural heritages; it introduces the new concept of ′Major Function Oriented Zone′ that include the major functions category, the stereo regional equilibrium mode, the two-level zoning specification, and the territorial development intensity; it offers a zoning scheme that defines development-optimized and development-prioritized zones as regions with massive urbanization and industrialization, development-restricted zones as ecological constructing or grain producing regions, development-prohibited zones as natural and cultural heritage protecting regions; and finally it addresses the main obstacle for implementing ′Major Function Oriented Zone′, which is the institutional arrangement of the supreme goal of high GDP growth rate that is currently being implemented.FAN Jie SUN Wei ZHOU Kan CHEN Dong 2012Chinese Geographical Science2012,22,2:31
6Adsorption characteristics of copper,lead,zinc and cadmium ions by tourmaline显示文摘The adsorption characteristics of heavy metals: Cu(II), Pb(II), Zn(II) and Cd(II) ions on tourmaline were studied. Adsor- ption equilibrium was established. The adsorption isotherms of all the four metal ions followed well Langmuir equation. Tourmaline was found to remove heavy metal ions efficiently from aqueous solution with selectivity in the order of Pb(II)>Cu(II)>Cd(II)>Zn(II). The adsorption of metal ions by tourmaline increased with the initial concentration of metal ions increasing in the medium. Tourmaline could also increase pH value of metal solution. The maximum heavy metal ions adsorbed by tourmaline was found to be 78.86, 154.08, 67.25, and 66.67 mg/g for Cu(II), Pb(II), Zn(II) and Cd(II), respectively. The temperature (25—55℃) had a small effect on the adsorption capacity of tourmaline. Competitive adsorption of Cu(II), Pb(II), Zn(II) and Cd(II) ions was also studied. The ad- sorption capacity of tourmaline for single metal decreased in the order of Pb>Cu>Zn >Cd and inhibition dominance observed in two metal systems was Pb>Cu, Pb>Zn, Pb>Cd, Cu>Zn, Cu>Cd, and Cd>Zn.JIANG Kan SUN Tie-heng SUN Li-na LI Hai-bo 2006Journal of Environmental Sciences2006,18,6:29
7Changes of Reactive Oxygen Species and Related Enzymes in Mitochondrial Respiration During Storage of Harvested Peach Fruits显示文摘Peach fruits [Prumus persica (L.) Batsch, cv. Yuhuasanhao] were used as materials to investigate the changes of reactive oxygen species (ROS) and related enzymes in mitochondria respiration during storage and then their influence on senescence of harvested Peach fruits was studied. The results showed that low temperature (5℃) strongly inhibited the reduction of firmness and the increase in respiration rate. During storage at ambient temperature (20℃), ROS had a cumulative process while malondialdehye (MDA) content continued to increase in associated with enhanced membrane lipid peroxidation. Lipoxygenase (LOX) activity was strongly inhibited under the low temperature condition. The activities of succinic dehydrogenase (SDH), cytochrome C oxidase (CCO), and Ca2+-ATPase declined to a certain extent at ambient temperature, while they showed higher activities at low temperature, which may be related to lower membrane lipid peroxidation at low temperature. Higher Ca2+ content at ambient temperature may be responsible for impairment of mitochondrial function, thus, leading to fruit senescence. The results showed that under low temperature condition, the low accumulation of ROS and the low level of membrane lipid peroxidation could maintain the function of mitochondria that would help to delay the senescence of peach fruits. These suggested a close relationship existed between ROS metabolism and mitochondrial respiration. It can be inferred that the low temperature helps to delay senescence of peach fruits via suppression of ROS and related enzymes, maintain better homeostasis of Ca2+ in mitochondria and thus better mitochondrial functions.KAN Juan WANG Hong-mei JIN Chang-hai 2011Agricultural Sciences in China2011,10,1:28
8Risk factors for early recurrence of small hepatocellular carcinoma after curative resection显示文摘BACKGROUND:Poorer prognosis is seen in patients with hepatocellular carcinoma (HCC) after curative hepatic resection with early recurrence (≤1 year) than in those with late recurrence (>1 year).This study aimed to identify risk factors for postoperative early recurrence of small HCC (≤3 cm in diameter).METHODS:The study population consisted of 158 patients who underwent curative resection for small HCC between January 2002 and July 2004.Risk factors for early recurrence were analyzed.RESULTS:Thirty-three (20.8%) patients developed early recurrence after surgery.Univariate analysis showed the following significant risk factors for early recurrence in small HCC:serum alpha-fetoprotein (AFP) level >100 ng/ml,lack of tumor capsule formation,microscopic vascular invasion,high Edmonson-Steiner grades,and cytokeratin-19 (CK-19) expression (P<0.05).Multivariate stepwise logistic regression analysis showed that serum AFP level >100 ng/ml (odds ratio 2.561,95% confidence interval 1.057 to 6.206,P=0.037) and microscopic vascular invasion (odds ratio 4.549,95% confidence interval 1.865 to 11.097,P=0.001) were independent factors.CONCLUSIONS:Postoperative early recurrence is related to serum AFP level >100 ng/ml and microscopic vascular invasion in patients with small HCC.Adjuvant therapy and careful follow-up are required for patients with these risk factors.Zhou, Yan-Ming Yang, Jia-Mei Li, Bin Yin, Zheng-Feng Xu, Feng Wang, Bin Xu, Wen Kan, Tong 2010Hepatobiliary & Pancreatic Diseases International2010,9,1:24
9Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management.Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng 2015Chinese Birds2015,,3:20
10Upregulation of Chemokine CXCL12 in the Dorsal Root Ganglia and Spinal Cord Contributes to the Development and Maintenance of Neuropathic Pain Following Spared Nerve Injury in Rats显示文摘Emerging evidence indicates that CXCL12/CXCR4 signaling is involved in chronic pain. However, few studies have systemically assessed its role in direct nerve injury-induced neuropathic pain and the underlying mechanism. Here, we determined that spared nerve injury(SNI)increased the expression of CXCL12 and its cognate receptor CXCR4 in lumbar 5 dorsal root ganglia(DRG)neurons and satellite glial cells. SNI also induced longlasting upregulation of CXCL12 and CXCR4 in the ipsilateral L4–5 spinal cord dorsal horn, characterized by CXCL12 expression in neurons and microglia, and CXCR4 expression in neurons and astrocytes. Moreover, SNIinduced a sustained increase in TNF-a expression in the DRG and spinal cord. Intraperitoneal injection(i.p.) of the TNF-a synthesis inhibitor thalidomide reduced the SNI-induced mechanical hypersensitivity and inhibited the expression of CXCL12 in the DRG and spinal cord.Intrathecal injection(i.t.) of the CXCR4 antagonist AMD3100, both 30 min before and 7 days after SNI,reduced the behavioral signs of allodynia. Rats given an i.t.or i.p. bolus of AMD3100 on day 8 of SNI exhibited attenuated abnormal pain behaviors. The neuropathic pain established following SNI was also impaired by i.t. administration of a CXCL12-neutralizing antibody. Moreover,repetitive i.t. AMD3100 administration prevented the activation of ERK in the spinal cord. The mechanical hypersensitivity induced in na?¨ve rats by i.t. CXCL12 was alleviated by pretreatment with the MEK inhibitor PD98059. Collectively, our results revealed that TNF-a might mediate the upregulation of CXCL12 in the DRG and spinal cord following SNI, and that CXCL12/CXCR4 signaling via ERK activation contributes to the development and maintenance of neuropathic pain.Liying Bai Xinru Wang Zhisong Li Cunlong Kong Yonghui Zhao Jun-Liang Qian Quancheng Kan Wei Zhang Ji-Tian Xu 2016Neuroscience Bulletin2016,32,1:20

13Acupuncture improves dendritic structure and spatial learning and memory ability of Alzheimer's disease mice显示文摘Acupuncture can improve the cognitive state of Alzheimer's disease, but its mechanism is not clear. Dendritic atrophy and synaptic loss in Alzheimer's disease brain are positively correlated with cognitive damage. Therefore, we speculated that the effect of acupuncture on improving cognitive function may be associated with reduced dendritic damage in the brain. Acupuncture at Qihai(CV6), Zhongwan(CV12), Danzhong(CV17), bilateral Zusanli(ST36), and bilateral Xuehai(SP10) acupoints was performed once a day(1-day rest after 6-day treatment) for 14 consecutive days. Senescence-accelerated mouse prone 8(SAMP8) mice without acupuncture and senescence-accelerated mouse resistant 1(SAMR1) mice were used as normal controls. After 14 days of treatment, spatial learning and memory ability of mice was assessed in each group using the Morris water maze. Dendritic changes of pyramidal cells in the hippocampal CA1 region were analyzed by quantitative Golgi staining. Our results showed that acupuncture shortened escape latency and lengthened retention time of the former platform quadrant in SAMP8 mice. Further, SAMP8 mice exhibited a significant increase in the number of apical and basal dendritic branches and total length of apical and basal dendrites after acupuncture. These results suggest that acupuncture improves spatial learning and memory ability of middle-aged SAMP8 mice by ameliorating dendritic structure.Bo-Hong Kan Jian-Chun Yu Lan Zhao Jie Zhao Zhen Li Yan-Rong Suo Jing-Xian Han 2018Neural Regeneration Research2018,13,8:18
14STUDY ON THE SHOCK WAVE CRYSTALLIZATION OF AMORPHOUS ALLOYS BY DSC显示文摘Shock wave and annealing crystallization of amorphous alloys FeSiB, FeMoSiB andFeCuNbSiB were studied by isothermal and non-isothermal DSC technique. It wasfound that the shock wave crystallization is very perfect, the fraction crystallized isvery close to 100%, though the period of crystallization is very short, only about10-4-10-6 s. Their produced phases differ from the parent phase in structure andcomposition. The high velocity of the transformation is very difficult to explain by thediffusion theory of solid state phase transition.H. Y. Zhao, H. Wang, Q.J. Liu, J.D. Kan and Z.Q.

15Immediate Effects of Hegu Needling on Adhesive Scapulohumeral Periarthritis显示文摘Objective:To observe the immediate effects of Hegu needling at Ashi points in patients with adhesive scapulohumeral periarthritis (SP). Methods:A total of 60 SP cases were randomized into a treatment group and a control group, 30 in each group. Cases in the treatment group were treated with Hegu needling at Ashi points and normal needling at other local points. Cases in the control group were treated with normal needling at local points alone. The therapeutic efficacy was then evaluated and analyzed using short-form of McGill pain questionnaire (SF-MPQ) and Japanese Orthopaedic Association (JOA) shoulder scoring system. Results:Hegu needling at Ashi points can substantially alleviate pain in patients with adhesive SP, showing a statistically significant difference when compared with the control group (P<0.01 or P<0.05). In addition, cases in the treatment group obtained better effects in abductor muscle strength, endurance, arm raising, internal rotation, external rotation, activities of daily living (ADL) and joint stability than those in the control group (P<0.01 or P<0.05). Conclusion:Hegu needling at Ashi points is effective for adhesive SP.Fan Xiao-peng Cheng Bo Huang Yin Gu Kan Zong Lei Han Chou-ping 2013Journal of Acupuncture and Tuina Science2013,11,4:17

18Bayesian Reliability Modeling and Assessment Solution for NC Machine Tools under Small-sample Data显示文摘Although Markov chain Monte Carlo(MCMC) algorithms are accurate, many factors may cause instability when they are utilized in reliability analysis; such instability makes these algorithms unsuitable for widespread engineering applications. Thus, a reliability modeling and assessment solution aimed at small-sample data of numerical control(NC) machine tools is proposed on the basis of Bayes theories. An expert-judgment process of fusing multi-source prior information is developed to obtain the Weibull parameters' prior distributions and reduce the subjective bias of usual expert-judgment methods. The grid approximation method is applied to two-parameter Weibull distribution to derive the formulas for the parameters' posterior distributions and solve the calculation difficulty of high-dimensional integration. The method is then applied to the real data of a type of NC machine tool to implement a reliability assessment and obtain the mean time between failures(MTBF). The relative error of the proposed method is 5.8020×10-4 compared with the MTBF obtained by the MCMC algorithm. This result indicates that the proposed method is as accurate as MCMC. The newly developed solution for reliability modeling and assessment of NC machine tools under small-sample data is easy, practical, and highly suitable for widespread application in the engineering field; in addition, the solution does not reduce accuracy.YANG Zhaojun KAN Yingnan CHEN Fei XU Binbin CHEN Chuanhai YANG Chuangui 2015Chinese Journal of Mechanical Engineering2015,28,6:16
19Accurate energy model for WSN node and its optimal design显示文摘With the development of CMOS and MEMS technologies, the implementation of a large number of wireless distributed micro-sensors that can be easily and rapidly deployed to form highly redundant, self-configuring, and ad hoc sensor networks. To facilitate ease of deployment, these sensors operate on battery for extended periods of time. A particular challenge in maintaining extended battery lifetime lies in achieving communications with low power. For better understanding of the design tradeoffs of wireless sensor network (WSN), a more accurate energy model for wireless sensor node is proposed, and an optimal design method of energy effcient wireless sensor node is described as well. Different from power models ever shown which assume the power cost of each component in WSN node is constant, the new one takes into account the energy dissipation of circuits in practical physical layer. It shows that there are some parameters, such as data rate, carrier frequency, bandwidth, Tsw, etc, which have a significant effect on the WSN node energy consumption per useful bit (EPUB). For a given quality specification, how energy consumption can be reduced by adjusting one or more of these parameters is shown.Kan Baoqiang Cai Li Zhu Hongsong Xu Yongjun 2008Journal of Systems Engineering and Electronics2008,19,3:16
20Prognostic factors in the surgical treatment of caudate lobe hepatocellular carcinoma显示文摘AIM:To evaluate the short-and long-term outcomes of liver resection for caudate lobe hepatocellular carcinoma (HCC).METHODS:We retrospectively analyzed 114 consecutive patients with HCC,originating from the caudate lobe,who underwent resection between January 2001 and January 2007.Univariate and multivariate analyses were performed on several clinicopathologic variables to determine the factors affecting long-term outcome and intrahepatic recurrence.RESULTS:Overall mortality and morbidity were 0% and 18%,respectively.After a median follow-up of 31 mo (interquartile range,11-66 mo),tumor recurrence had occurred in 76 patients (66.7%).The 1-,3-,and 5-year disease-free survival rates were 65.7%,38.1%,and 18.4%,respectively.The 1-,3-,and 5-year overall survival rates were 76.1%,54.7%,and 31.8%,respectively.Univariate analysis showed that subsegmental location of the tumor (45.7% vs 16.2%,P=0.01),liver cirrhosis (12.3% vs 47.9%,P=0.03),surgical margin (18.5% vs 54.6%,P=0.04),vascular invasion (37.9% vs 23.2%,P=0.04) and extended caudate resection (42.1% vs 15.4%,P=0.04) were related to poorer long-term survival.Multivariate analysis showed that only subsegmental location of the tumor,liver cirrhosis and surgical margin were significant independent prognostic factors.CONCLUSION:Hepatectomy was an effective treatment for HCC in the caudate lobe.The subsegmental location of the tumor,liver cirrhosis and surgical margin affected long-term survival.Peng Liu,Jia-Mei Yang,Wen-Yang Niu,Tong Kan,Feng Xie,Dian-Qi Li,Ye Wang,Yan-Ming Zhou,Department of Special Treatment and Liver Transplantation,Eastern Hepatobiliary Surgery Hospital,Second Military Medical University,Shanghai 200438,China Peng Liu,Department of Hepatobiliary Surgery,Navy General Hospital,Beijing 100037,China 2010World Journal of Gastroenterology2010,16,9:15
