1半干旱黄土丘陵区纯林土壤腐殖质异化特征及与其他性质的关系显示文摘纯林长期生长或多代连栽必然会导致土壤腐殖质含量和构成发生异化,探究这种异化特征及其与土壤其他性质的关系可以为纯林管理或混交改造提供科学依据。通过对半干旱黄土丘陵区南泥湾林场8种典型纯林土壤腐殖质及其他性质进行系统检测,结果表明:(1)侧柏林土壤腐殖质含量最高(34.61 g/kg),腐殖化程度和稳定性一般;白榆和白桦林土壤的腐殖质含量中等(19.69—23.58 g/kg)、腐殖化程度和稳定性最佳;茶条槭和小叶杨林土壤的腐殖质含量(20.59—22.53 g/kg)和构成均为中等水平;油松、沙棘和刺槐林土壤的腐殖质质量较低(11.77—13.81 g/kg),且腐殖化程度较低,稳定性相对最差;(2)与胡敏酸含量存在显著相互促进作用(P<0.05)的土壤性质为CEC、N、微生物量和蛋白酶活性(相关系数0.769—0.926,下同),存在显著相互抑制作用的为有效Cu(-0.793);与富啡酸存在显著相互促进作用的为N、CEC、微生物量、蔗糖酶和磷酸酶活性(0.836—0.955),存在显著相互抑制作用的为有效Cu(-0.822);与胡敏素存在显著相互促进作用的为N、CEC、微生物量、磷酸酶活性和有效Zn(0.766—0.951),存在显著相互抑制作用的为脱氢酶活性(-0.784)。(3)腐殖质构成与其他性质的相关性均不显著(P>0.05),其中相对有利于提高胡敏酸/腐殖酸含量之比的土壤性质为蛋白酶、蔗糖酶和过氧化氢酶活性,而不利的是脱氢酶活性;相对有利于提高胡敏酸/富啡酸含量之比的为速效K、CEC和脲酶活性,而不利的是脱氢酶活性。(4)总体而言土壤腐殖质含量较之腐殖质构成与其他性质之间具有更大的相关性;向土壤增施N肥可以促进腐殖质的形成,增加K肥则有利于腐殖质构成的改善,而通过混交改造或增加林下植被是促进纯林土壤腐殖质化过程和解决土壤退化的根本措施。张晓曦 刘增文 朱博超 邴塬皓 于齐 Luc Nhu Trung 2015生态学报2015,35,6:13
2Impacts of mixed litter decomposition from Robinia pseudoacacia and other tree species on C loss and nutrient release in the Loess Plateau of China显示文摘The productivity of Robinia pseudoacacia(R.p.) pure forest usually declines at the late growth stage,and reforming it into mixed forests could be a promising way to resolve this problem. When choosing a suitable tree species that can be mixed with R.p., the interspecific relationship is an important issue. Therefore, we gathered the autumn litter fall from R.p. and 10 other species from the Loess Plateau of China were mixed in dual species litterbags(R.p.+each other species) and buried them in soil for a 345 days lab decay incubation. We measured the litter mass loss and nutrient contents to determine whether the nutrient release was affected by mixed species litter decomposition. The impacts of mixed litter decomposition on macro-elements release were more obvious than on micro-elements. The litters with similar substrate quality might show variable impacts on nutrients release in mixed decomposition. The C loss and release of nutrient was improved by descending order when R.p. litter was mixed with Hippophae rhamnoides, Ulmus pumila, Populus simonii, Larix principis-rupprechtii and Quercus liaotungensis(Q.l.). But, except for Q.l., only the other species were recommended as suitable mix-plants for R.p. since promoting a high turnover of the nutrient in the litter compartment and a rapid availability for tree.Xiaoxi Zhang Zengwen Liu Bochao Zhu Yuanhao Bing Nhu Trung Luc Liangzhen Du Zhenhua Zhu 2016Journal of Forestry Research2016,27,3:10

4Value of a new stick-type rapid urine test for the diagnosis of Helicobacter pylori infection in the Vietnamese population显示文摘AIM:To assess the value of a new test for the diagnosis of Helicobacter pylori(H.pylori) infection,Rapirun H.pylori Antibody Stick(Rapirun Stick),in a Vietnamese population.METHODS:Eligible patients without previous history of H.pylori eradication were recruited.Rapid urease test(RUT) and histologic examination were used to diagnose the H.pylori infection.Patients were considered H.pylori positive when the RUT results were positive and/or the bacteria were detected histologically.Rapirun Stick tests were performed using urine samples,and the results were compared with the other 2 methods.RESULTS:We enrolled 200 patients with a mean age of 36(range,18-76) years.There were 116 females and 84 males.Of the 200 patients,111(55.5%) were diagnosed as being H.pylori positive.The sensitivity,specificity,and accuracy of the Stick test were 84.7%,89.9%,and 87.0%,respectively.There were 17(8.5%) falsenegative patients and 9(4.5%) false-positive patients.CONCLUSION:The Rapirun Stick test has high sensitivity,specificity,and accuracy for the diagnosis of H.pylori infection in the Vietnamese population.The test can be clinically applied in Vietnamese populations.Duc T Quach Toru Hiyama Fumio Shimamoto Quang D Le Linh X Ho Nhu HT Vu Masaharu Yoshihara Naomi Uemura 2014World Journal of Gastroenterology2014,20,17:4
5Pulmonary complications of transcatheter arterial chemoembolization for hepatocellular carcinoma显示文摘Transcatheter arterial chemoembolization(TACE) is an effective palliative intervention that is widely accepted for the management of hepatocellular carcinoma(HCC). Post-TACE pulmonary complications resulting in acute lung injury(ALI) or acute respiratory distress syndrome(ARDS) are rare events. Pulmonary complications after TACE are thought to be related to chemical injury subsequent to the migration of the infused ethiodized oil or chemotherapeutic agent to the lung vasculature, facilitated by arteriovenous(AV) shunts within the hyper-vascular HCC. We review herein the literature on pulmonary complications related to TACE for HCC. Post-TACE pulmonary complications have included pulmonary oil embolism, interstitial pneumonitis, chemical pneumonitis, ALI, ARDS, lipoid pneumonia, acute eosinophilic and neutrophilic pneumonia, bilious pleuritis, pulmonary abscess, pulmonary tumor embolism, and possibly pulmonary metastasis with HCC. The risk factors associated with post-TACE pulmonary complications identified in the literature include large hyper-vascular HCC with AV shunts, large-volume Lipiodol infusion, and embolization via the right inferior phrenic artery. However, the absence of known risk factors is not a guarantee against serious complications. An astute awareness of the potential post-TACE pulmonary complications should expedite appropriate therapeutic interventions and increase potential for early recovery.Quan M Nhu Harry Knowles Paul J Pockros Catherine T Frenette 2016World Journal of Respirology2016,6,3:4
6渭北残塬沟壑区牧草枯落物对油松和侧柏纯林土壤极化的修复效应显示文摘纯林对土壤养分的选择性利用和单一枯落物的特殊影响是导致人工林土壤极化的重要原因,利用牧草枯落物施肥或直接营造林草复合植被是防治和修复纯林土壤极化的最快捷且有效的措施。针对渭北残塬沟壑区的油松(Pinus tabuliformis)和侧柏(Platycladus orientalis)人工纯林,在前期关于土壤极化的研究基础上,通过7种常见豆科牧草枯落物与林地腐殖质层土壤的混合培养试验,研究不同牧草枯落物对针叶纯林土壤极化的修复效应,以此作为选择适宜修复牧草种的依据。结果表明:对油松纯林土壤,苜蓿(Medicago sativa)具有明显的综合修复效应,其次为红豆草(Onobrychis viciaefolia),可作为与油松复合种植的优选牧草,而胡枝子(Leapedeza bicolor)、毛苕子(Vicia villosa)和沙打旺(Astragalus adsurgens)造成土壤性质一定的衰退;对侧柏纯林土壤,红豆草具有明显的综合修复效应,其次为苜蓿和草木樨(Melilotus officinalis),可作为与侧柏复合种植的优选牧草,而毛苕子和小冠花则造成土壤性质一定的衰退。邴塬皓 刘增文 Luc Nhu Trung 朱博超 张晓曦 于齐 2014草地学报2014,22,3:3

8Effect of petroleum on decomposition of shrub–grass litters in soil in Northern Shaanxi of China显示文摘The impacts of petroleum contamination on the litter decomposition of shrub–grass land would directly influence nutrient cycling, and the stability and function of ecosystem. Ten common shrub and grass species from Yujiaping oil deposits were studied. Litters from these species were placed into litterbags and buried in petroleum-contaminated soil with 3levels of contamination(slight, moderate and serious pollution with petroleum concentrations of 15, 30 and 45 g/kg, respectively). A decomposition experiment was then conducted in the lab to investigate the impacts of petroleum contamination on litter decomposition rates. Slight pollution did not inhibit the decomposition of any litters and significantly promoted the litter decomposition of Hippophae rhamnoides, Caragana korshinskii, Amorpha fruticosa, Ziziphus jujuba var. spinosa, Periploca sepium, Medicago sativa and Bothriochloa ischaemum. Moderate pollution significantly inhibited litter decomposition of M. sativa,Coronilla varia, Artemisia vestita and Trrifolium repens and significantly promoted the litter decomposition of C. korshinskii, Z. jujuba var. spinosa and P. sepium. Serious pollution significantly inhibited the litter decomposition of H. rhamnoides, A. fruticosa, B. ischaemum and A. vestita and significantly promoted the litter decomposition of Z. jujuba var. spinosa, P.sepium and M. sativa. In addition, the impacts of petroleum contamination did not exhibit a uniform increase or decrease as petroleum concentration increased. Inhibitory effects of petroleum on litter decomposition may hinder the substance cycling and result in the degradation of plant communities in contaminated areas.Xiaoxi Zhang Zengwen Liu Qi Yu Nhu Trung Luc Yuanhao Bing Bochao Zhu Wenxuan Wang 2015Journal of Environmental Sciences2015,27,7:3
9Indications for and techniques of keratoplasty at Vietnam National Institute of Ophthalmology显示文摘AIM:To report the indications for and techniques of corneal transplantation at Vietnam National Institute of Ophthalmology(VNIO) over a period of 12y(2002-2013).· METHODS:Records of patients who had undergone corneal transplantation at VNIO from January 1,2002 to January 1,2014 were reviewed to determine the indication for and type of corneal transplant performed.Patient age,gender,indication for corneal transplantation and surgical technique were recorded and analyzed.· RESULTS:Corneal transplantation were underwent in1390 eyes of 1278 patients with a mean age of 44.9±18.1y during the period under review.The most common indication was infectious corneal ulcer(n =670;48.2%),followed by corneal scar(n =333,24.0%),corneal dystrophy(n=138,9.9%) and failed graft(n=112,8.1%).Nearly all procedures performed were penetrating keratoplasty(n=1300,93.5%),with a few lamellar keratoplasty procedures performed:lamellar keratoplasty(n=52,3.7%),Descemet's stripping automated endothelial keratoplasty(n =27,1.9%) and deep anterior lamellar keratoplasty(n =11,0.8%).· CONCLUSION:While the most common indication for keratoplasty was infectious keratitis,nearly all indications for corneal transplantation were managed with penetrating keratoplasty.However,lamellar keratoplasty techniques,including deep anterior lamellar keratoplasty and Descemet's stripping automated endothelial keratoplasty,are being performed with increasing frequency for isolated stromal and endothelial disorders,respectively.Pham Ngoc Dong Truong Nhu Han Anthony J.Aldave Hoang Thi Minh Chau 2016International Journal of Ophthalmology(English edition)2016,9,3:3
10Role of Aedes aegypti and Aedes albopictus during the 2011 dengue fever epidemics in Hanoi, Vietnam显示文摘Objective: To record the human cases of dengue fever(DF) and investigate the Aedes mosquito species circulating during the Hanoi 2011 DF epidemics. Methods: 24 different outbreak points were recorded in 8 districts between August and December 2011. Results: 140 patients were hospitalized following dengue diagnostic with a predominance of males(59.3%) and the 15-34 age class. Only DENV-1(11.27%) and DENV-2(88.73%) serotypes were detected in human samples. Mosquito sampling performed in and around patients households revealed the predominance of Aedes aegypti(95.15%) versus Aedes albopictus(4.85%). There is a positive correlation between the population density of Aedes aegypti and the number of human cases and duration of outbreaks. Conclusions: This was not observed for Aedes albopictus. 3 pools of Aedes aegypti were positive with dengue virus, two with DENV-1 and one with DENV-2.Pham Thi Kim Lien Vu Trong Duoc Laurent Gavotte Emmanuel Cornillot Phan Thi Nga Laurence Briant Roger Frutos Tran Nhu Duong 2015Asian Pacific Journal of Tropical Medicine2015,8,7:2
11Development of a PARCS/Serpent model for neutronics analysis of the Dalat nuclear research reactor显示文摘Cross-sectional homogenization for full-core calculations of small and complex reactor configurations,such as research reactors,has been recently recognized as an interesting and challenging topic.This paper presents the development of a PARCS/Serpent model for the neutronics analysis of a research reactor type TRIGA Mark-II loaded with Russian VVR-M2 fuel(known as the Dalat Nuclear Research Reactor or DNRR).The full-scale DNRR model and a supercell model for a shim/safety rod and its surrounding fuel bundles with the Monte Carlo code Serpent 2 were proposed to generate homogenized fewgroup cross sections for full-core diffusion calculations with PARCS.The full-scale DNRR model with Serpent 2 was also utilized as a reference to verify the PARCS/Serpent calculations.Comparison of the effective neutron multiplication factors,radial and axial core power distributions,and control rod worths showed a generally good agreement between PARCS and Serpent 2.In addition,the discrepancies between the PARCS and Serpent 2 results are also discussed.Consequently,the results indicate the applicability of the PARCS/Serpent model for further steady state and transient analyses of the DNRR.Viet-Phu Tran Kien-Cuong Nguyen Donny Hartanto Hoai-Nam Tran Vinh Thanh Tran Van-Khanh Hoang Pham Nhu Viet Ha 2021Nuclear Science and Techniques2021,32,2:2

15Identifying nursing research priorities in Vietnam: a modified Delphi study显示文摘Objective: There is no single study that has examined nursing research priorities in Vietnam. This study aimed to gain consensus from experts on the nursing research priorities in Vietnam.Methods: A three-round modified Delphi study was used in this study. A focus group discussion among experts was conducted in round I to identify the nursing research priorities(n=23). Data in round I were analyzed using content analysis. In round Ⅱ, participants were invited to rate the importance of each nursing priority topic in a 5-point Likert scale questionnaire, which had a 74%(n=17) response rate. In round Ⅲ, the questionnaire was returned to the experts(n=17) until consensus was reached. Data from round Ⅱ and round Ⅲ were analyzed to produce mean score and final rank.Results: The top 12 research priority lists were identified, which included subthemes and areas of possible investigations. All priorities were classified into three groups in the rank order, namely:(i) nursing management and leadership, which included(1) nursing care quality,(2) management and leadership of nurse managers,(3) nursing image,(4) professional nurse competency, and(5) human resource management;(ii) nursing education, which included(1) knowledge-specific domain,(2) the linkage between education and practice, and(3) nurse teacher workforce;and(iii) nursing service, which included(1) adult nursing concern,(2) patient safety,(3) public health nursing concern, and(4) quality of life of patients and nurses.Conclusions: Consensus among experts was achiever, and the findings are considered as the basis of resources to the most essential research needs in Vietnam.Yupin Aungsuroch Xuan Ha Thi Nhu Tran Thuy Khanh Linh Rapin Polsook Rungrawee Navicharern Joko Gunawan 2019Frontiers of Nursing2019,6,4:1
