| 1 | Fluid Inclusion and H-O Isotope Geochemistry of the Phapon Gold Deposit, NW Laos: Implications for Fluid Source and Ore Genesis显示文摘The Phapon gold deposit, located in northern Laos, is a unique large-scale gold deposit in Luang Prabang-Loei metallogenic belt. It is hosted in the Lower Permian limestone and controlled by a NE-trending ductile-brittle fault system. There are three types of primary ore including auriferous calcite vein type, disseminated type, and breccia type, and the first two are important in the Phapon gold deposit. Based on fluid inclusion petrography and microthermometry, three types of primary fluid inclusions including type 1 liquid-rich aqueous, type 2 vapor-rich aqueous and type 3 daughter mineralbearing aqueous were identified in hydrothermal calcite grains. The ore-forming fluids are normally homogeneous, as indicated by the widespread type 1 inclusions with identical composition. The coexistence of type 1 and type 2 inclusions, showing similar final homogenization temperature but different compositions, indicate that fluid immiscibility did locally take place in both two types of ores. The results of microthermometry and H-O isotopes geochemistry indicate that there are little differences on ore-fluid geochemistry between the auriferous calcite vein-type and disseminated type ores. The oreforming fluids are characterized by medium-low temperatures(157–268 oC) and low salinity(1.6 wt.%–9.9 wt.% NaCl eq.). It is likely to have a metamorphic-dominant mixed source, which could be associated with dehydration and decarbonisation of Lower Permian limestone and Middle–Upper Triassic sandstones during the dynamic metamorphism. The fluid-wallrock interaction played a major role, and the locally occurred fluid-immiscible processes played a subordinate role in gold precipitation. Combined with the regional and ore deposit geology, and ore-fluid geochemistry, we suggest that the Phapon gold deposit is best considered to be a member of the epizonal orogenic deposit class. | Linnan Guo Shusheng Liu Lin Hou Jieting Wang Meifeng Shi Qiming Zhang Fei Nie Yongfei Yang Zhimin Peng | 2019 | Journal of Earth Science2019，30，1： | 11 |

| 3 | Expression of neurocan mRNA and ultrastructure of brain tissue after cerebral ischemia and reperfusion in stroke-prone renovascular hypertensive rats treated by electroacupuncture显示文摘We established a stroke-prone renovascular hypertensive rat model by bilateral constriction of the renal artery with sliver loop clips. After ten weeks, middle cerebral artery occlusion was induced for 2 hours. The rats then received electro-acupuncture at Baihui (DU 20) and Dazhui (DU 14) after onset of ischemia for 30 days. In situ hybridization study showed that electroacupuncture significantly reduced the number of neurocan mRNA-positive cells in the ischemic penumbra and hippocampal tissues of rats. Electron microscopy results demonstrated that the structure of neurons and blood vessels in the ischemic tissues were restored with electroacupuncture. Overall, these data suggest that electroacupuncture may protect neurons against ischemic reperfusion injury in stroke-prone renovascular hypertensive rats, which may be regulated by downregulation of expression of nerve inhibitory factor neurocan mRNA. | Feng Tan Saiying Wan Haike Wu Qiwen HUO Jinliang Wang Wenlin Chen Meifeng Fang Xiaolin Liu Xuewen Wang Jingbo Sun | 2011 | Neural Regeneration Research2011，6，36： | 8 |
| 4 | Effect of electrolysis voltage on electrochemical reduction of titanium oxide to titanium in molten calcium chloride显示文摘The electrochemical reduction of solid TiO2 directly to solid metal is a promising alternative to the current Kroll process. The present work is aimed at studying the effect of electrolysis voltage on the rate of electrochemical reduction. The products of electrochemical reduction of TiO2 and Ti2O were examined using the scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques. The results show that Ti2O was reduced to low valent titanium oxide at 1.5-1.7 V, which was the result of ionization of oxygen. TiO2 and Ti2O were reduced to titanium metal at 2.1-3.1 V, which was the co-action of ionization of oxygen and calciothermic reduction. The oxygen content decreased rapidly with voltage increas-ing from 2.1 to 2.6 V, while it changed little from 2.6 to 3.1 V. The optimized cell voltage was 2.6-3.1 V. | LIU Meifeng LU Shigang KAN Surong LI Guoxun | 2007 | Rare Metals2007，26，6： | 7 |
| 5 | Geochronology and Petrochemistry of Volcanic Rocks in the Xaignabouli Area, NW Laos显示文摘An integrated study of zircon U-Pb geochronology and petrochemistry, together with zircon Lu-Hf isotopes, has been carried out on the basaltic-andesitic tuff and volcanic breccia from the Nam Hang Formation and andesitic tuff from the Muang-Nan Formation in the Xaignabouli area, which had been mapped as the Permian–Early Triassic on the 1 : 1 000 000 geological map or Late Carboniferous on the 1 : 200 000 geological maps. Zircon U-Pb dating of three samples yielded weighted mean ages of 235±2.6, 232±1.4 and 278±2.8 Ma, respectively, suggesting a Late Triassic origin for the Nam Hang Formation and an Early Permian origin for the Muang-Nan Formation. Geochemically, they are characterized by depletions in HFSEs(e.g., Nb, Ta, Ti) and high LILE/HFSE ratios, and they have positive zircon ε_(Hf)(t) values of 8.7–15.9, which exhibits the continental arc volcanic affinity and partial melting of subducting oceanic slab in the magma source. Combined with spatial occurrence of the volcanic rock and existing geochronological and geochemical data, we suggest that the Xaignabouli-Luang Prabang volcanic belt can be linked to the Loei-Phetchabun belt. The Permian–Triassic volcanic rocks in this belt might be a product of the Nan back-arc basin eastward subduction. | Meifeng Shi Zhenbo Wu Shusheng Liu Zhimin Peng Linnan Guo Fei Nie Siwei Xu | 2019 | Journal of Earth Science2019，30，1： | 6 |
| 6 | Spatial Differentiation and Influencing Mechanism of Medical Care Accessibility in Beijing:A Migrant Equality Perspective显示文摘Spatial equality of access to basic public services, especially medical care services which are directly related to life safety, is the first step to achieve the goal of equalization of basic public services for all the people proposed by central government of China. Using the spatial analysis and the statistical analysis, this study evaluates the spatial differentiation of medical care facilities accessibility by constructing STT(Shortest Travel-Time) and SAI(Spatial Accessibility Index). And then this study explores the neighborhood effects on the medical care facilities accessibility in Beijing, with a particular focus on the effect of neighborhood migrant proportion by constructing spatial dependent regression model. The spatial accessibility analysis of medical care facilities show that the spatial distribution of medical care facilities was basically consistent with administrative regions but not with population demands. Bivariate LISA cluster maps identify that suburban areas are the overlapped clusters of high percent of migrants and limited medical care services. This is associated with the public service allocation rule in China, which stresses equality within urban areas and within rural areas but overlooks equality between urban areas and rural areas; and stresses local resident demands but overlooks migrant demands. To estimate the effects on medical care accessibility of neighborhood migrant proportion, spatial dependence models are applied due to spatial dependence of accessibility of medical care facilities. The regression results show that neighborhoods with high percent of migrants, even conditioning on neighborhood SES, are related to limited spatial accessibility of medical care services. Besides neighborhood characteristics, another important factor influencing spatial accessibility of medical care services is the process of spatial spillover effects. This indicates that the attenuate accessibility of medical care services for migrants is not only because of their own constraints but also because of their proximity to other disadvantaged neighborhoods. Therefore, it is urgently needed to increase the medical facilities in the suburban areas, to take into account migrants' demands and to reduce residential segregation between local residents and migrants for local governments to achieve the goal of equalization of medical care service. | ZHAO Meifeng LIU Shenghe QI Wei | 2018 | Chinese Geographical Science2018，28，2： | 5 |
| 7 | Prognostic value of interim ^(18)F-FDG PET/CT in diffuse large B-cell lymphoma显示文摘Objective: Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease. The prognostic factor currently used is not accurate enough to predict the outcomes of patients with DLBCL. The prognostic significance of interim PET/CT in DLBCL remains controversial. The aim of this study is to determine the predictive value of interim 18F-FDG PET/CT after first-line treatment in patients with DLBCL. Methods: Thirty-two patients with DLBCL underwent baseline, interim and post-treatment 18F-FDG PET/CT scans. Imaging results were analyzed for the survival of patients via software SPSS 13.0, retrospectively. Results: Thirty-one of the 32 patients were treated with R-CHOP regimen, and interim 18F-FDG PET/CT of 24 patients was performed after 2 cycles of treatment. After a median follow-up period of 16.7 months, the 2-year progression-free survival (PFS) rates were significantly different between the groups above and below SUV max cut-off value of 2.5 (P=0.039). No significant differences were found in the 2-year PFS rates if SUV max cut-off values were set as 2.0 and 3.0, respectively (P=0.360; P=0.113). Conclusions: Interim PET/CT could predict the prognosis of DLBCL patients with the SUV max cut-off value of 2.5, but more clinical data should be concluded to confirm this conclusion. | Zhitao Ying Xuejuan Wang Yuqin Song Wen Zheng Xiaopei Wang Yan Xie Ningjing Lin Meifeng Tu Lingyan Ping Weiping Liu Lijuan Deng Chen Zhang Zhi Yang Jun Zhu | 2013 | Chinese Journal of Cancer Research2013，25，1： | 4 |

| 9 | Exploring the differential impacts of urban transit system on the spatial distribution of local and floating population in Beijing显示文摘流动人口成为了城市的人口的主要司机瓷器大城市里的过多的生长。城市的运输系统(UTS ) 是在人口的一个重要因素在城市的区域以内的空间分布,特别快速、高能力的运输系统。这份报纸在北京大城市的区域(BMA ) 分析在 2000 和 2010 之间的高速公路和地铁的延期的原因的效果,集中于本地居民和流动人口之间的组差别。由于交通改进和人口生长的 endogeneity,仪器的变量(IV ) 回归模型被使用避免这个问题。结果证明本地居民在内部郊区增加了,但是在城市中心减少了,当流动人口在多数区域增加了时。IV 回归结果证明城市的运输系统的扩展越过 BMA 在人口生长上有统计上重要的影响。结果也证明城市的地铁系统的延期越过 BMA 比本地居民在流动人口上有更多的效果。它被城市的地铁系统的相当低的费用主要引起。这暗示城市的地铁系统上的过多的津贴能导致过多的流动人口生长和居住区别,甚至居住的分离。因此,计划并且设计合理、科学的城市的运输系统以便推进合理人口尺寸并且支持居住集成是必要的。而且,地区性的分析证明本地居民上的城市的交通改进的效果不在内部郊区是统计上重要的。它暗示城市的交通改进在劝诱人搬到郊外的区域并且在北京控制中心城市人口上限制了效果。因此,它应该被强调在城市的计划和人口的进程的人口分发上的城市的交通改进的区分的效果控制。 | ZHAO Meifeng LIU Shenghe QI Wei | 2017 | Journal of Geographical Sciences2017，27，6： | 4 |
| 10 | Prognostic value of pre-and post-transplantation 18F-fluorodeoxyglucose positron emission tomography results in non-Hodgkin lymphoma patients receiving autologous stem cell transplantation显示文摘Objective: High-dose chemotherapy(HDC) followed by autologous stem cell transplantation(ASCT) is the standard of care in the upfront or relapsed/refractory setting in some patients with non-Hodgkin lymphoma(NHL).However,a proportion of patients do not respond to ASCT.^(18)F-fluorodeoxyglucose(FDG) positron emission tomography(PET)/computed tomography(CT) has been widely used for staging,response evaluation,and prognosis prediction.Here,we investigated the prognostic role of PET/CT in NHL patients before and after ASCT.Methods: A retrospective study was conducted at Peking University Cancer Hospital.All NHL patients who underwent ASCT between March 2010 and July 2016 were identified.Patients who had PET/CT scan before and after ASCT were included.Deauville criteria(5-point scale) were used to interpret PET scans.Univariate and multivariate survival analyses were performed using Cox regression.The predictive value of PET scanning was estimated by comparing the area under the receiver operating characteristic(ROC) curve.Results: In total,79 patients were enrolled in this study.In univariate analysis,pre-and post-ASCT PET result was identified as prognostic factors for 3-year progression-free survival(PFS) and overall survival(OS).Patients with negative pre-ASCT PET result demonstrated significantly better PFS(84.2% vs.54.2%) and OS(89.2% vs.63.6%) than patients with positive pre-ASCT PET result.PFS(91.6% vs.25.3%) and OS(96.5% vs.36.8%) were also significantly different between patients with negative and positive post-ASCT PET result.Multivariate analysis also showed a significant association between survival and post-ASCT PET result.ROC analysis revealed that the predictive value of post-ASCT PET result was superior to that of pre-ASCT PET result alone.Combined pre-and post-ASCT PET result is better for predicting outcomes in patients with NHL receiving transplantation.Deauville criteria score >3 was identified as the best cutoff value for post-ASCT PET.Conclusions: Post-ASCT PET result was more important than pre-ASCT PET result in predicting outcomes for NHL patients who underwent ASCT.The prognostic significance can be improved when combining preASCT PET result with post-ASCT PET result.Deauville criteria can be used for interpreting PET scans in this scenario. | Zhitao Ying Lan Mi Xuejuan Wang Yuewei Zhang Zhi Yang Yuqin Song Xiaopei Wang WenZheng Ningjing Lin Meifeng Tu Yan Xie Lingyan Ping Chen Zhang Weiping Liu LijuanDeng Jun Zhu | 2017 | Chinese Journal of Cancer Research2017，29，6： | 3 |
| 11 | Geology, Geochronology, and Hf Isotopic Composition of the Pha Lek Fe Deposit, Northern Laos: Implications for Early Permian Subduction-Related Skarn Fe Mineralization in the Truong Son Belt显示文摘The Truong Son metallogenic belt in central Laos and Vietnam is an important Fe-Cu-Sn-Au polymetallic ore district. The Pha Lek Fe deposit is closely related to Late Carboniferous– Early Permian I-type granitic magmatism, and contains >50 Mt @ 45% to 50% of Fe ore. Ore minerals occur mainly as magnetite and hematite in the skarn alteration zone between a granitic pluton and metamorphosed Middle–Upper Devonian carbonates. The granitic pluton comprises granodiorite and granite, with zircon U-Pb dating indicating synchronous emplacement at 288.2±1.3 and 284.9±1.2 Ma, respectively. Zircons from these granitoids have ε_(Hf)(t) values of 2.9–11.2 and relatively young TDM2 ages(<1.0 Ga), indicating an origin by partial melting of depleted mafic crust or magma mixing. Previous studies have shown that these granitoids have high Y, Yb, and K_2O contents, and low Sr and Na_2O contents, which are interpreted as the melting of mafic continental crust. Pyrite of the main mineralization stage yields an ^(187)Re/^(188)Os-^(187)Os/^(188)Os isochron age of 287±17 Ma, indicating that mineralization is associated with Pha Lek granitic magmatism. A Late Carboniferous–Early Permian subduction-related skarn-type Fe mineralization model is proposed for the Pha Lek deposit. More evidence is needed to verify a hypothesis of volcanic overprinting during Late Triassic post-collisional extension. | Lin Hou Shusheng Liu Linnan Guo Fuhao Xiong Chao Li Meifeng Shi Qiming Zhang Siwei Xu Songyang Wu | 2019 | Journal of Earth Science2019，30，1： | 2 |
| 12 | PEG-asparaginase in BFM-90 regimen improves outcomes in adults with newly diagnosed lymphoblastic lymphoma显示文摘Objective: Although L-asparaginase(L-ASP) is a standard treatment for lymphoblastic lymphoma(LBL),hypersensitivity reactions by some patients limit its application. Polyethylene glycol-conjugated asparaginase(PEGASP) has a lower immunogenicity and is a standard treatment in all pediatric acute lymphoblastic leukemia(ALL).In this study, we investigated the efficacy and toxicity of PEG-ASP instead of L-ASP as used in the BFM-90regimen(PEG-ASP-BFM-90) for adult LBL.Methods: Between June 2012 and July 2015, we treated 30 adult patients with newly diagnosed LBL, using PEGASP-BFM-90 in a prospective, multicenter and single-arm clinical study at 5 participating institutions in China.Results: All the 30 patients, including 19 males and 11 females with a median age of 30(range: 18–62) years,completed 128 times of the PEG-ASP, with the median of 4(range: 2–6) times. Patients did not receive radiotherapy at this time. The overall response rate was 86.7%(26/30), with 50.0%(15/30) complete response and36.7%(11/30) partial response. The 3-year overall survival was 46.0% [95% confidence interval(95% CI),28.2%–64.8%], and the 3-year progression-free survival was 43.0%(95% CI, 25.7%–62.0%). Major adverse events were myelosuppression, reduced fibrinogen, liver dysfunction and digestive tract toxicities. No allergic reaction and no treatment-related mortality or severe complications were recorded.Conclusions: Our clinical data and observed outcomes indicate that 1 dose of PEG-ASP can replace multiple doses of native L-ASP in BFM-90, with predominantly grade 3–4 neutropenia for adult LBL, and no therapyrelated deaths. The effect is similar to previous reports of PEG-ASP-containing regimens for adult ALL. Major advantages include less serious allergic reactions, 2–3 weeks of action duration, and convenience for patients and physicians. | Wen Zheng Hanyun Ren Xiaoyan Ke Mei Xue Yongqing Zhang Yan Xie Ningjing Lin Meifeng Tu Weiping Liu Lingyan Ping Zhitao Ying Chen Zhang Lijuan Deng Xiaopei Wang Yuqin Song Jun Zhu | 2017 | Chinese Journal of Cancer Research2017，29，1： | 2 |
| 13 | A durable 4-1BB-based CD19 CAR-T cell for treatment of relapsed or refractory non-Hodgkin lymphoma显示文摘Objective:Previous studies reported that 4-1BB-based CD19 chimeric antigen receptor(CAR)-T cells were more beneficial for the clinical outcomes than CD28-based CAR-T cells,especially the lower incidence rate of severe adverse events.However,the median progression-free survival(mPFS)of 4-1BB-based product Kymriah was shorter than that of CD28-based Yescarta(2.9 months vs.5.9 months),suggesting that Kymriah was limited in the long-term efficacy.Thus,a safe and durable 4-1BB-based CD19 CAR-T needs to be developed.Methods:We designed a CD19-targeted CAR-T(named as IM19)which consisted of an FMC63 scFv,4-1BB and CD3ζintracellular domain and was manufactured into a memory T-enriched formulation.A phase I/II clinical trial was launched to evaluate the clinical outcomes of IM19 in relapsed or refractory(r/r)B cell non-Hodgkin lymphoma(B-NHL).Dose-escalation investigation(at a dose of 5×10^(5)/kg,1×10^(6)/kg and 3×106/kg)was performed in 22 r/r B-NHL patients.All patients received a single infusion of IM19 after 3-day conditional regimen.Results:At month 3,the overall response rate(ORR)was 59.1%,the complete response rate(CRR)was 50.0%.The mPFS was 6 months and the 1-year overall survival rate was 77.8%.Cytokine release syndrome(CRS)occurred in 13 patients(59.1%),with 54.5%of grade 1−2 CRS.Only one patient(4.5%)experienced grade 3 CRS and grade 3 neurotoxicity.Conclusions:These results demonstrated the safety and durable efficacy of a 4-1BB-based CD19 CAR-T,IM19,which is promising for further development and clinical investigation. | Zhitao Ying Ting He Shanzhao Jin Xiaopei Wang Wen Zheng Ningjing Lin Meifeng Tu Yan Xie Lingyan Ping Weiping Liu Lijuan Deng Yanping Ding Xuelian Hu Bing Bu Xin’an Lu Yuqin Song Jun Zhu | 2022 | Chinese Journal of Cancer Research2022，34，1： | 2 |
| 14 | Laser patterning for the study of MSC cardiogenic differentiation at the single-cell level显示文摘Mesenchymal stem cells(MSCs)have been cited as contributors to heart repair through cardiogenic differentiation and multiple cellular interactions,including the paracrine effect,cell fusion,and mechanical and electrical couplings.Due to heart–muscle complexity,progress in the development of knowledge concerning the role of MSCs in cardiac repair is heavily based on MSC–cardiomyocyte coculture.In conventional coculture systems,however,the in vivo cardiac muscle structure,in which rod-shaped cells are connected end-to-end,is not sustained;instead,irregularly shaped cells spread randomly,resulting in randomly distributed cell junctions.Consequently,contact-mediated cell–cell interactions(e.g.,the electrical triggering signal and the mechanical contraction wave that propagate through MSC–cardiomyocyte junctions)occur randomly.Thus,the data generated on the beneficial effects of MSCs may be irrelevant to in vivo biological processes.In this study,we explored whether cardiomyocyte alignment,the most important phenotype,is relevant to stem cell cardiogenic differentiation.Here,we report(i)the construction of a laser-patterned,biochip-based,stem cell–cardiomyocyte coculture model with controlled cell alignment;and(ii)single-cell-level data on stem cell cardiogenic differentiation under in vivo-like cardiomyocyte alignment conditions. | Zhen Ma Qiuying Liu Huaxiao Yang Raymond B Runyan Carol A Eisenberg Meifeng Xu Thomas K Borg Roger Markwald Yifei Wang Bruce Z Gao | 2013 | Light(Science & Applications)2013，2，1： | 2 |
| 15 | Prognostic value of ^(18)F-fluorodeoxyglucose positron emission tomography using Deauville criteria in diffuse large B cell lymphoma treated with autologous hematopoietic stem cell transplantation显示文摘Objective: High-dose chemotherapy(HDC) followed by autologous hematopoietic stem cell transplantation(auto-HSCT) plays an important role in improving outcomes of diffuse large B cell lymphoma(DLBCL) patients.18 F-fluorodeoxyglucose(18 F-FDG) positron emission tomography(PET)/computed tomography(CT) has been widely accepted in response assessment and prediction of prognosis in DLBCL. Here, we report the value of 18 FFDG PET/CT pre-and post-HSCT in predicting outcomes of patients with DLBCL.Methods: DLBCL patients who had PET/CT scan before and after HSCT were included. PET results were interpreted based upon Deauville criteria. The prognostic value of 18 F-FDG PET/CT in auto-HSCT was evaluated.Results: Eighty-four patients were enrolled. In univariate analysis, pre-and post-HSCT PET findings were correlated with 3-year progression-free survival(PFS) [hazard ratio(HR)=4.391, P=0.001; HR=7.607, P<0.001] and overall survival(OS)(HR=4.792, P=0.008; HR=26.138, P<0.001). Patients receiving upfront auto-HSCT after firstline treatment had better outcomes than relapsed/refractory DLBCL patients(3-year PFS, P<0.001; 3-year OS,P<0.001). In the relapsed/refractory patients, pre-and post-HSCT PET findings were also associated with 3-year PFS(P=0.003 vs. P<0.001) and OS(P=0.027 vs. P<0.001). A significant correlation was observed between clinical response to chemotherapy before auto-HSCT and outcomes of patients in the entire cohort(3-year PFS, P<0.001;3-year OS, P<0.001) and in the subgroup of 21 patients with positive pre-HSCT PET(3-year PFS, P=0.084; 3-year OS, P=0.240). A significant association between survival and post-HSCT PET findings was observed in multivariate analysis(HR=5.168, P<0.001).Conclusions: PET results before and after HSCT are useful prognostic factors for DLBCL patients receiving HSCT. Patients who responded to chemotherapy, even those with positive pre-HSCT PET, are appropriate candidates for auto-HSCT. | Zhitao Ying Lan Mi Nina Zhou Xuejuan Wang Zhi Yang Yuqin Song Xiaopei Wang Wen Zheng Ningjing Lin Meifeng Tu Yan Xie Lingyan Ping Chen Zhang Weiping Liu Lijuan Deng Jun Zhu | 2019 | Chinese Journal of Cancer Research2019，31，1： | 2 |
| 16 | Evaluation on Salt Tolerance of 25 Species of Poplar Cuttings in Lab显示文摘The growth and morphological characteristics of 25 species of poplar were investigated. The cuttings were cultivated in Hoagland Nutrient Solution, which was made with sodium chloride (NaCl) solutions of concentration of 1.00, 3.00, 4.00, 5.00, 6.00, and 8.00 g/L, respectively. Under such salt stress, the new branch length and biomass accumulation of cuttings decreased as the salt concentration increased. The root/shoot ratio of most of species showed an escalation and then reduction tendency. Under low concentration of salt (NaCl ≤4.00 g/L), the root/shoot ratio of 11 species increased, compared to NaCl =1.00 g/L. After salt treatments, with the increase of salinity concentration, the content of chlorophyll of 8 species decreased. Based on the analysis of growth and morphological appearance, it turned out that 6 species had high salt-tolerant, 7 species were moderate salt-tolerant, 7 species were low salt-tolerant and 5 species failed to resist salt stress. | JI Meifeng YIN Jiandao LIU Zhenying HUO Jia’nan GUO Rui | 2011 | Chinese Forestry Science and Technology2011，10，3： | 1 |
