2Fractionation of Heavy Metals in Sediments from Dianchi Lake,China显示文摘FVactionation of heavy metals in sediments can help in understanding potential hazards of heavy metals. The present study analyzed total concentrations and fractions of selected heavy metals (Cd, Cr, Cu, Pb, and Zn) in surface sediments from Dianchi Lake, Yunnan Province, China, as well as factors that may affect distributions of the various heavy metal fractions. Total concentrations of the heavy metals decreased in the order Zn > Cu > Pb > Cr > Cd. These heavy metals, except Cr, were much higher than their background levels, indicating that Dianchi Lake was polluted by Cd, Zn, Pb, and Cu. Cadmium occurred mainly as the non-residual fraction (sum of the HOAc-soluble, reducible, and oxidizable fractions) (97.6%), and Zn (55.7%) was also predominantly found in the non-residual fraction. In contrast, most of the Cr (88.5%), Pb (81.8%), and Cu (59.2%) occurred in the residual fraction. Correlation analysis showed that total heavy metal concentrations, organic matter and reducible Fe were the main factors affecting the distributions of the various heavy metal fractions. In the Waihai section of Dianchi Lake (comprising 97% of the lake area), the concentrations of Cd, Zn, Pb, and Cu in the non-residual fraction were significantly lower (P < 0.01 or 0.05) than those of the Caohai section (3% of the lake area). This indicated that potential heavy metal hazards in the Caohai section were greater than the Waihai section.LI Ren-Ying YANG Hao ZHOU Zhi-Gao Lü Jun-Jie SHAO Xiao-Hua JIN Feng 2007Pedosphere2007,17,2:29

4Chinese Trauma Surgeon Association for management guidelines of vacuum sealing drainage application in abdominal surgeries-Update and systematic review显示文摘Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chin ese Trauma Surge on Associati on orga nized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries.Eleven questions regarding the use of VSD in abdominal surgeries were addressed:(1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions?(2) Can VSD be preventively used for a high-risk abdominal incision w让h primary suture?(3) Can VSD be used in severely contaminated/infected abdominal surgical sites?(4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome?(5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage?(6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula?(7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess?(8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects?(9) Does VSD in crease the risk of bleeding?(10) Does VSD increase the risk of intestinal wail injury?(11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.Yang Li Pei-Yuan Li Shi-Jing Sun Yuan-Zhang Yao Zhan-Fei Li Tao Liu Fan Yang Lian-Yang Zhang Xiang-Jun Bai Jing-Shan Huo Wu-Bing He Jun Ouyang Lei Peng Ping Hu Yan-An Zhu Ping Jin Qi-Feng Shao Yan-Feng Wang Rui-Wu Dai Pei-Yang Hu Hai-Ming Chen Ge-Fei Wang Yong-Gao Wang Hong-Xu Jin Chang-Ju Zhu Qi-Yong Zhang Biao Shao Xi-Guang Sang Chang-Lin Yin 2019Chinese Journal of Traumatology2019,22,1:26
5Climate change regionalization in China(1961–2010)显示文摘Since climatic condition is the important foundation for human subsistence and development and the key factor in sustainable development of economy and society, climate change has been a global issue attracting great attentions of politicians, scientists, governments, and the public alike throughout the world. Existing climate regionalization in China aims to characterize the regional differences in climate based on years of the mean value of different climate indexes. However, with the accelerating climate change nowadays, existing climate regionalization cannot represent the regional difference of climate change, nor can it reflect the disasters and environmental risks incurred from climate changes. This paper utilizes the tendency value and fluctuation value of temperature and precipitation from 1961 to 2010 to identify the climate change quantitatively, and completes the climate change regionalization in China(1961–2010) with county administrative regionalization as the unit in combination with China's terrain feature. Level-I regionalization divides China's climate change(1961–2010) into five tendency zones based on the tendency of temperature and precipitation, which are respectively Northeast China-North China warm-dry trend zone, East China-Central China wet-warm trend zone, Southwest China-South China dry-warm trend zone, Southeast Tibet-Southwest China wet-warm trend zone, and Northwest China-Qinghai-Tibet Plateau warm-wet trend zone; level-II regionalization refers to fourteen fluctuation regions based on level-I regionalization according to the fluctuation of temperature and precipitation.SHI PeiJun SUN Shao WANG Ming LI Ning WANG JingAi JIN YunYun GU XiaoTian YIN WeiXia 2014Science China Earth Sciences2014,57,11:22

10Genotypic Characterization of Methicillin-resistant Staphylococcus aureus Isolated from Pigs and Retail Foods in China显示文摘Objective To investigate the genotypic diversity of Methicillin-resistant Staphylococcus aureus(MRSA) isolated from pigs and retail foods from different geographical areas in China and further to study the routes and rates of transmission of this pathogen from animals to food. Methods Seventy-one MRSA isolates were obtained from pigs and retail foods and then characterized by multi-locus sequencing typing(MLST), spa typing, multiple-locus variable number of tandem repeat analysis(MLVA), pulsed-field gel electrophoresis(PFGE), and antimicrobial susceptibility testing. Results All isolated MRSA exhibited multi-drug resistance(MDR). Greater diversity was found in food-associated MRSA(7 STs, 8 spa types, and 10 MLVA patterns) compared to pig-associated MRSA(3 STs, 1 spa type, and 6 MLVA patterns). PFGE patterns were more diverse for pig-associated MRSA than those of food-associated isolates(40 vs. 11 pulse types). Among the pig-associated isolates, CC9-ST9-t899-MC2236 was the most prevalent clone(96.4%), and CC9-ST9-t437-MC621(20.0%) was the predominant clone among the food-associated isolates. The CC9-ST9 isolates showed significantly higher antimicrobial resistance than other clones. Interestingly, CC398-ST398-t034 clone was identified from both pig-and food-associated isolates. Of note, some community-and hospital-associated MRSA strains(t030, t172, t1244, and t4549) were also identified as food-associated isolates. Conclusion CC9-ST9-t899-MC2236-MDR was the most predominant clone in pigs, but significant genetic diversity was observed in food-associated MRSA. Our results demonstrate the great need for improved surveillance of MRSA in livestock and food and effective prevention strategies to limit MDR-MRSA infections in China.WANG Wei LIU Feng ZULQARNAIN Baloch ZHANG Cun Shan MA Ke PENG Zi Xin YAN Shao Fei HU Yu Jie GAN Xin DONG Yin Ping BAI Yao LI Feng Qin YAN Xiao Mei MA Ai Guo XU Jin 2017Biomedical and Environmental Sciences2017,30,8:13
11Broadband tunable liquid crystal terahertz waveplates driven with porous graphene electrodes显示文摘Versatile devices,especially tunable ones,for terahertz imaging,sensing and high-speed communication,are in high demand.Liquid crystal based components are perfect candidates in the optical range;however,they encounter significant challenges in the terahertz band,particularly the lack of highly transparent electrodes and the drawbacks induced by a thick cell.Here,a strategy to overcome all these challenges is proposed:Few-layer porous graphene is employed as an electrode with a transmittance of more than 98%.A subwavelength metal wire grid is utilized as an integrated high-efficiency electrode and polarizer.The homogeneous alignment of a high-birefringence liquid crystal is implemented on both frail electrodes via a non-contact photo-alignment technique.A tunable terahertz waveplate is thus obtained.Its polarization evolution is directly demonstrated.Furthermore,quarter-wave plates that are electrically controllable over the entire testing range are achieved by stacking two cells.The proposed solution may pave a simple and bright road toward the development of various liquid crystal terahertz apparatuses.Lei Wang Xiao-Wen Lin Wei Hu Guang-Hao Shao Peng Chen Lan-Ju Liang Biao-Bing Jin Pei-Heng Wu Hao Qian Yi-Nong Lu Xiao Liang Zhi-Gang Zheng Yan-Qing Lu 2015Light(Science & Applications)2015,4,1:13

13Buyang Huanwu Decoction fraction protects against cerebral ischemia/reperfusion injury by attenuating the inflammatory response and cellular apoptosis显示文摘Buyang Huanwu Decoction fraction extracted from Buyang Huanwu Decoction contains saponins of Astragalus, total paeony glycoside and safflower flavones. The aim of this study was to demonstrate the neuroprotective effect and mechanism of Buyang Huanwu Decoction fraction on ischemic injury both in vivo and in vitro. In vivo experiments showed that 50-200 mg/kg Buyang Huanwu Decoction fraction reduced infarct volume and pathological injury in ischemia/reperfusion rats, markedly inhibited expression of nuclear factor-κB and tumor necrosis factor-α and promoted nestin protein expression in brain tissue. Buyang Huanwu Decoction fraction (200 mg/kg) exhibited significant effects, which were similar to those of 100 mg/kg Ginkgo biloba extract. In vitro experimental results demonstrated that 10-100 mg/L Buyang Huanwu Decoction fraction significantly improved cell viability, decreased the release of lactate dehydrogenase and malondialdehyde levels, and inhibited the rate of apoptosis in HT22 cells following oxygen-glucose deprivation. Buyang Huanwu Decoction fraction (100 mg/L) exhibited significant effects, which were similar to those of 100 mg/L Ginkgo biloba extract. These findings suggest that Buyang Huanwu Decoction fraction may represent a novel, protective strategy against cerebral ischemia/reperfusion injury in rats and oxygen-glucose deprivation-induced damage in HT22 cells in vitro by attenuating the inflammatory response and cellular apoptosis.Yulian Jin Liuyi Dong Changqing Wu Jiang Qin Sheng Li Chunyan Wang Xu Shao Dake Huang 2013Neural Regeneration Research2013,8,3:11
14Helicobacter pylori infection and esophageal cancer risk:An updated meta-analysis显示文摘AIM:To clarify the association between Helicobacter pylori(H.pylori)infection and the risk of esophageal carcinoma through a meta-analysis of published data.METHODS:Studies which reported the association between H.pylori infection and esophageal cancer published up to June 2013 were included.The odds ratios(ORs)and corresponding 95%CIs of H.pyloriinfection on esophageal cancer with respect to health control groups were evaluated.Data were extracted independently by two investigators and discrepancies were resolved by discussion with a third investigator.The statistical software,STATA(version 12.0),was applied to investigate heterogeneity among individual studies and to summarize the studies.A meta-analysis was performed using a fixed-effect or random-effect method,depending on the absence or presence of significant heterogeneity.RESULTS:No significant association between H.pylori infection and esophageal squamous cell carcinoma(ESCC)risk was found in the pooled overall population(OR=0.97,95%CI:0.76-1.24).However,significant associations between H.pylori infection and ESCC risk were found in Eastern subjects(OR=0.66,95%CI:0.43-0.89).Similarly,cytotoxin-associated gene-A(CagA)positive strains of infection may decrease the risk of ESCC in Eastern subjects(OR=0.77,95%CI:0.65-0.92),however,these associations were not statistically significant in Western subjects(OR=1.26,95%CI:0.97-1.63).For esophageal adenocarcinoma(EAC)the summary OR for H.pylori infection and CagA positive strains of infection were 0.59(95%CI:0.51-0.68)and 0.56(95%CI:0.45-0.70),respectively.CONCLUSION:H.pylori infection is associated with a decreased risk of ESCC in Eastern populations and a decreased risk of EAC in the overall population.Fa-Jun Xie Yi-Ping Zhang Qiu-Qing Zheng Hong-Chuan Jin Fa-Liang Wang Ming Chen Lan Shao De-Hong Zou Xin-Min Yu Wei-Min Mao 2013World Journal of Gastroenterology2013,19,36:11

17Biodrying of municipal solid waste with high water content by combined hydrolytic-aerobic technology显示文摘The high water content of municipal solid waste(MSW)will reduce the effciency of mechanical sorting,consequently unfavorable for beneficial utilization.In this study,a combined hydrolytic-aerobic biodrying technology was introduced to remove water from MSW.The total water removals were proved to depend on the ventilation frequency and the temporal span in the hydrolytic stage. The ventilation frequency of 6 times/d was preferable in the hydrolytic stage.The hydrolytic span should not be prolonged more than 4 d.At this optimal scenario,the final water content was 50.5%reduced from the initial water content of 72.0%,presenting a high water removal effciency up to 78.5%.A positive correlation was observed between the organics losses and the water losses in both hydrolytic and aerobic stages(R=0.944,p<0.01).The evolutions of extracellular enzyme activities were shown to be consistent with the organics losses.ZHANG, Dongqing HE, Pinjing SHAO, Liming JIN, Taifeng HAN, Jingyao 2008Journal of Environmental Sciences2008,20,12:10
18Optimal midcourse trajectory cluster generation and trajectory modification for hypersonic interceptions显示文摘The hypersonic interception in near space is a great challenge because of the target's unpredictable trajectory, which demands the interceptors of trajectory cluster coverage of the predicted area and optimal trajectory modification capability aiming at the consistently updating predicted impact point(PIP) in the midcourse phase. A novel midcourse optimal trajectory cluster generation and trajectory modification algorithm is proposed based on the neighboring optimal control theory. Firstly, the midcourse trajectory optimization problem is introduced; the necessary conditions for the optimal control and the transversality constraints are given.Secondly, with the description of the neighboring optimal trajectory existence theory(NOTET), the neighboring optimal control(NOC)algorithm is derived by taking the second order partial derivations with the necessary conditions and transversality conditions. The revised terminal constraints are reversely integrated to the initial time and the perturbations of the co-states are further expressed with the states deviations and terminal constraints modifications.Thirdly, the simulations of two different scenarios are carried out and the results prove the effectiveness and optimality of the proposed method.Humin Lei Jin Zhou Dailiang Zhai Lei Shao Dayuan Zhang 2017Journal of Systems Engineering and Electronics2017,28,6:10

20Alleviation by abscisic acid of Al toxicity in rice bean is not associated with citrate efflux but depends on ABI5-mediated signal transduction pathways显示文摘Under conditions of aluminum(Al) toxicity,which severely inhibits root growth in acidic soils, plants rapidly alter their gene expression to optimize physiological fitness for survival. Abscisic acid(ABA) has been suggested as a mediator between Al stress and gene expression, but the underlying mechanisms remain largely unknown. Here,we investigated ABA-mediated Al-stress responses, using integrated physiological and molecular biology approaches.We demonstrate that Al stress caused ABA accumulation in the root apex of rice bean(Vigna umbellata [Thunb.] Ohwi &Ohashi), which positively regulated Al tolerance. However,this was not associated with known Al-tolerance mechanisms. Transcriptomic analysis revealed that nearly one-third of the responsive genes were shared between the Al-stress and ABA treatments. We further identified a transcription factor, ABI5, as being positively involved in Al tolerance. Arabidopsis abi5 mutants displayed increased sensitivity to Al, which was not related to the regulation of AtALMT1 and AtMATE expression. Functional categorization of ABI5-mediated genes revealed the importance of cell wall modification and osmoregulation in Al tolerance, a finding supported by osmotic stress treatment on Al tolerance. Our results suggest that ABA signal transduction pathways provide an additional layer of regulatory control over Al tolerance in plants.Wei Fan Jia Meng Xu Pei Wu Zhi Xin Yang He Qiang Lou Wei Wei Chen Jian Fen Jin Shao Jian Zheng Jian Li Yang 2019Journal of Integrative Plant Biology2019,61,2:9
