| 1 | Linking atmospheric pollution to cryospheric change in the Third Pole region: current progress and future prospects显示文摘The Tibetan Plateau and its surroundings are known as the Third Pole(TP). This region is noted for its high rates of glacier melt and the associated hydrological shifts that affect water supplies in Asia. Atmospheric pollutants contribute to climatic and cryospheric changes through their effects on solar radiation and the albedos of snow and ice surfaces; moreover, the behavior and fates within the cryosphere and environmental impacts of environmental pollutants are topics of increasing concern. In this review, we introduce a coordinated monitoring and research framework and network to link atmospheric pollution and cryospheric changes(APCC) within the TP region. We then provide an up-to-date summary of progress and achievements related to the APCC research framework, including aspects of atmospheric pollution’s composition and concentration, spatial and temporal variations, trans-boundary transport pathways and mechanisms, and effects on the warming of atmosphere and changing in Indian monsoon, as well as melting of glacier and snow cover. We highlight that exogenous air pollutants can enter into the TP’s environments and cause great impacts on regional climatic and environmental changes. At last, we propose future research priorities and map out an extended program at the global scale. The ongoing monitoring activities and research facilitate comprehensive studies of atmosphere–cryosphere interactions, represent one of China’s key research expeditions to the TP and the polar regions and contribute to the global perspective of earth system science. | Shichang Kang Qianggong Zhang Yun Qian Zhenming Ji Chaoliu Li Zhiyuan Cong Yulan Zhang Junming Guo Wentao Du Jie Huang Qinglong You Arnico K.Panday Maheswar Rupakheti Deliang Chen Orjan Gustafsson Mark H.Thiemens Dahe Qin | 2019 | National Science Review2019，6，4： | 35 |

| 3 | The altered expression of inflammation-related microRNAs with microRNA-155 expression correlates with Th17 differentiation in patients with acute coronary syndrome显示文摘MicroRNAs(miRNAs)are a novel class of small,non-coding RNAs that play a significant role in both inflammatory and cardiovascular diseases.Immune cells,especially T helper(Th)cells,are critical in the development of atherosclerosis and the onset of acute coronary syndrome(ACS).To assess whether inflammation-related miRNAs(such as miR-155,146a,21,125a-5p,125b,31)are involved in the imbalance of Th cell subsets in patients with ACS,we measured the expression of related miRNAs in patients with acute myocardial infarction(AMI),unstable angina(UA),stable angina(SA)and chest pain syndrome(CPS);analyzed the relationship between miRNA expression and the frequency of Th cell subsets;and observed the co-expression of miR-155 and IL-17A in peripheral blood mononuclear cells(PBMCs)of patients with ACS.The results showed that the expression of miR-155 in the PBMCs of patients with ACS was decreased by approximately 60%,while the expression of both miR-21 and miR-146a was increased by approximately twofold.The expression patterns of miRNAs in plasma correlated with those in PBMCs,except for miR-21,which was increased by approximately sixfold in the AMI group and showed no significant difference between the UA group and the CPS group.We also found that the expression of miR-155 inversely correlated with the frequency of Th17 cells(r520.896,P,0.01)and that miR-155 was co-expressed with IL-17A in patients with ACS.In conclusion,our study revealed the expression patterns of inflammation-related miRNAs in patients with ACS and found that miR-155 may be associated with Th17 cell differentiation. | Rui Yao Yulan Ma Youyou Du Mengyang Liao Huanhuan Li Wei Liang Jing Yuan Zhijun Ma Xian Yu Hong Xiao Yuhua Liao | 2011 | Cellular & Molecular Immunology2011，8，6： | 32 |

| 5 | Variation in needle and cone traits in natural populations of Pinus yunnanensis显示文摘Pinus yunnanensis Franch. is a major component of coniferous forests in southwestern China. Little is known about its intraspecific variation. Morphological variations in needle and cone traits of P. yunnanensis were analyzed to quantify variability among and within natural populations.Seven traits were measured on 10 needles collected from 30 trees in each of the 18 sampled populations of P. yunnanensis. Four cone traits were measured in 221 individual trees from nine populations. The results showed that there were significant differences(p \ 0.01) both among populations and within populations in each needle and cone trait.The proportion of phenotypic variation of nearly all needle and cone traits was over 50 % within populations, which showed trees within populations accounted for a majority of the total variation. The needle traits showed higher variability within population than cone traits. Variability in theneedle traits was correlated with geo-climatic parameters(longitude, latitude, altitude, temperature, and precipitation).Needle length and the ratio of needle length to fascicle sheath length showed clinal variation in response to latitudinal and altitudinal gradients. A hierarchical classification of all populations based on needle traits led to the formation of four major groups. The findings provide important genetic information for the evaluation of variation. Moreover, it will assist in management of genetic diversity of P. yunnanensis. | Yulan Xu Keith Woeste Nianhui Cai Xiangyang Kang Genqian Li Shi Chen Anan Duan | 2016 | Journal of Forestry Research2016，27，1： | 15 |
| 6 | Antibacterial effects of platelet-rich fibrin produced by horizontal centrifugation显示文摘Platelet-rich fibrin(PRF)has been widely used owing to its ability to stimulate tissue regeneration.To date,few studies have described the antibacterial properties of PRF.Previously,PRF prepared by horizontal centrifugation(H-PRF)was shown to contain more immune cells than leukocyte-and platelet-rich fibrin(L-PRF).This study aimed to compare the antimicrobial effects of PRFs against Staphylococcus aureus and Escherichia coli in vitro and to determine whether the antibacterial effects correlated with the number of immune cells.Blood samples were obtained from eight healthy donors to prepare L-PRF and H-PRF.The sizes and weights of L-PRF and H-PRF were first evaluated,and their antibacterial effects against S.aureus and E.coli were then tested in vitro using the inhibition ring and plate-counting test methods.Flow-cytometric analysis of the cell components of L-PRF and H-PRF was also performed.No significant differences in size or weight were observed between the L-PRF and H-PRF groups.The H-PRF group contained more leukocytes than the L-PRF group.While both PRFs had notable antimicrobial activity against S.aureus and E.coli,H-PRF demonstrated a significantly better antibacterial effect than L-PRF.Furthermore,the antimicrobial ability of the PRF solid was less efficient than that of wet PRF.In conclusion,H-PRF exhibited better antibacterial activity than L-PRF,which might have been attributed to having more immune cells. | Mengge Feng Yulan Wang Peng Zhang Qin Zhao Shimin Yu Kailun Shen Richard J.Miron Yufeng Zhang | 2020 | International Journal of Oral Science2020，12，4： | 12 |
| 7 | Effect of dry density on ^(125)I diffusion in GMZ bentonite显示文摘Gaomiaozi(GMZ) bentonite is regarded as the favorable candidate backfilling material for a potential repository in China.It is important to understand the diffusion behavior of 125 I in GMZ bentonite and compare the diffusion behavior in GMZ and other types of bentonite like MX-80,Avonlea,etc.Therefore,through-and out-diffusion experiments were conducted to obtain the effective diffusion coefficient(D e) and distribution coefficient(K d).A computer code named Fitting for diffusion coefficient(FDP) was used for the experimental data processing and theoretical modeling.At the dry density of GMZ bentonite from 1600-2000 kg/m 3,the D e values of 125 I were(2.4-20.4) × 10-12 m 2 /s and K d values were constants.At dry density above 1800 kg/m 3,the diffusion behaviors were almost the same,indicating that the anion exclusion was ineffective.Out-diffusion results showed that the species of 125 I may be changed during the diffusion processing.It was probably caused by some organic matters or reducing substances in GMZ bentonite.Since the main composition of bentonite is montmorillonite,similar diffusion parameters were obtained in GMZ and other types of bentonite.The relationship of D e and accessible porosity(acc) could be described by Archie's law with exponent n = 1.2-2.8 for 125 I diffusion in bentonite,whereas n = 2.0 in GMZ bentonite.Furthermore,bentonite with the dry density of 1800 kg/m 3 was proposed as the backfilling materials used in the construction of high level radioactivity waste repository. | WU Tao LI JinYing DAI Wei XIAO GuoPing SHU FuJun YAO Jun SU YuLan SHI Lei | 2012 | Science China Chemistry2012，55，9： | 11 |
| 8 | Acupuncture therapy for angina pectoris:a systematic review显示文摘OBJECTIVE:To assess the effectiveness and safety of acupuncture therapy for angina pectoris.METHODS:Randomized controlled trials(RCTs) concerned with acupuncture treatment of angina pectoris were identified by searching Academic Source Premier,MEDLINE,Science Citation Index Expanded,and three Chinese databases(China biology medicine database,China national knowledge infrastructure,and VIP database for Chinese technical periodicals).The valid data were extracted in accordance with our inclusion and exclusion criteria.The main outcomes of the included studies were synthesized using Revman 5.1.RESULTS:Twenty-one articles on 16 individual studies were included and evaluated as having high or moderate risk of bias according to the standards of the Cochrane Collaboration.Meta-analysis indicated that acupuncture combined with conventional drugs(ACCD) was superior to conventional drugs alone in reducing the incidence of acute myocardial infarction(AMI) [OR=0.18,95%CI(0.04,0.84),P=0.03].Moreover,ACCD was superior to conventional drugs in the relief of angina symptoms [OR=4.23,95%CI(2.73,6.56),P<0.00001],and improvement of electrocardiography(ECG) [OR=2.61,95%CI(1.83,3.73),P<0.00001].Acupuncture by itselfwasalsosuperiortoconventionaldrugsforanginasymptoms[OR=3.59,95%CI(1.76,7.92),P=0.0004] and ECG improvement [OR=3.07,95%CI(1.54,6.10),P=0.001].ACCD was superior to conventional drugs in shortening the time to onset of angina relief [WMD=-1.40,95% CI(-1.65,-1.15),P< 0.00001].However,the time to onset was significantly longer for acupuncture treatment than for conventional treatment alone [WMD=2.43,95%CI(1.63,3.23),P<0.000 01].CONCLUSION:ACCD reduced the occurrence of AMI,and both acupuncture and ACCD relieved angina symptoms and improved ECG.However,compared with conventional treatment,acupuncture showed a longer delay before its onset of action.This indicates that acupuncture is not suitable for emergency treatment of heart attack.Owing to the poor quality of the current evidence,the findings of this systematic review need to be verified by more RCTs to enhance statistical power. | Ji Chen Yulan Ren Yong Tang Zhengjie Li Fanrong Liang | 2012 | Journal of Traditional Chinese Medicine2012，32，4： | 10 |
| 9 | Fatty acids, inflammation and intestinal health in pigs显示文摘The intestine is not only critical for nutrient digestion and absorption, but also is the largest immune organ in the body.However, in pig production, inflammation induced by numerous factors, such as pathogen infection and stresses(e.g.,weaning), results in intestinal mucosal injury and dysfunction, and consequently results in poor growth of pigs. Dietary fatty acids not only play critical roles in energy homeostasis and cel ular membrane composition, but also exert potent effects on intestinal development, immune function, and inflammatory response. Recent studies support potential therapeutic roles for specific fatty acids(short chain and medium chain fatty acids and long chain polyunsaturated fatty acids) in intestinal inflammation of pigs. Results of these new lines of work indicate trophic and cytoprotective effects of fatty acids on intestinal integrity in pigs. In this article, we review the effect of inflammation on intestinal structure and function, and the role of specific fatty acids on intestinal health of pigs, especial y under inflammatory conditions. | Yulan Liu | 2016 | Journal of Animal Science and Biotechnology2016，7，3： | 10 |
| 10 | Modulation of Gut Microbiota in Pathological States显示文摘人类微生态是寄居在人体中的微生物聚集体,且主要存在于胃肠道(GIT)中。肠道微生态随着人体发育而演化,并在人类健康和疾病中起着重要作用。近年来,由于微生态会影响宿主代谢、生理学和免疫系统发育,而且微生态紊乱可能导致许多疾病,其越来越受到人们的关注。肠道微生态可能与恶性肿瘤有一定联系,如胃癌和结直肠癌;也可能与其他一些疾病有关,如非酒精性脂肪肝(NAFLD)、被称为工业化世界'生活方式疾病'的肥胖和糖尿病、冠心病以及中枢神经系统紊乱。虽然分子技术革命为我们更准确地研究肠道微生态提供了必要的工具,但是我们需要更精确地阐明其与某些人类疾病病理变化的关系,明确微生态在不同疾病中的作用是新的治疗策略发展的基础。本文概述了肠道微生态对人类健康的重要影响以及调整肠道菌群结构的潜在用途,如菌群移植用于治疗耐药艰难梭菌(C.difficile)的感染。通过微生态干预调整肠道区域以改善人类健康的概念虽刚刚兴起,但其治疗意义显著。因此,抑制有害菌、促进有益菌可能会保护人类健康,并且这些努力将为探索发展更加合理的治疗方案打下基础。 | Yulan Wang BaohongWang Junfang wu xiangyang Jiang Huiru Tang Ole H.

| 11 | Dietary modulation of endogenous host defense peptide synthesis as an alternative approach to in-feed antibiotics显示文摘Traditionally, antibiotics are included in animal feed at subtherapeutic levels for growth promotion and disease prevention.However, recent links between in-feed antibiotics and a rise in antibiotic-resistant pathogens have led to a ban of all antibiotics in livestock production by the European Union in January 2006 and a removal of medically important antibiotics in animal feeds in the United States in January 2017.An urgent need arises for antibiotic alternatives capable of maintaining animal health and productivity without triggering antimicrobial resistance.Host defense peptides(HDP) are a critical component of the animal innate immune system with direct antimicrobial and immunomodulatory activities.While in-feed supplementation of recombinant or synthetic HDP appears to be effective in maintaining animal performance and alleviating clinical symptoms in the context of disease, dietary modulation of the synthesis of endogenous host defense peptides has emerged as a cost-effective,antibiotic-alternative approach to disease control and prevention.Several different classes of smallmolecule compounds have been found capable of promoting HDP synthesis.Among the most efficacious compounds are butyrate and vitamin D.Moreover, butyrate and vitamin D synergize with each other in enhancing HDP synthesis.This review will focus on the regulation of HDP synthesis by butyrate and vitamin D in humans, chickens, pigs, and cattle and argue for potential application of HDP-inducing compounds in antibiotic-free livestock production. | Kelsy Robinson Xi Ma Yulan Liu Shiyan Qiao Yongqing Hou Guolong Zhang | 2018 | Animal Nutrition2018，，2： | 9 |
| 12 | A method for estimating the contribution of evaporative vapor from Nam Co to local atmospheric vapor based on stable isotopes of water bodies显示文摘During the summer monsoon season,the moisture of precipitation events in southern and central regions of the Tibetan Plateau is mainly moisture from the Indian Ocean transported by the Indian monsoon and terrestrial vapor derived from the surface of the Tibetan Plateau.However,the respective contributions of these two types of moisture are not clear.From June to September,the excess deuterium values of precipitation and river water in the Nam Co basin are higher than those for the southern Tibetan Plateau.This reflects the mixing of evaporation from Nam Co and local atmospheric vapor.On the basis of theory for estimating the contribution of evaporative vapor from surface water bodies to atmospheric vapor and relative stable isotopes in water bodies (precipitation,river water,atmospheric moisture and lake water),this study preliminarily estimates that the average contribution of evaporation from the Lake Nam Co to local atmospheric vapor has varied from 28.4% to 31.1% during the summer monsoon season in recent years. | XU YanWei KANG ShiChang ZHANG YuLan ZHANG YongJun | 2011 | Chinese Science Bulletin2011，56，14： | 7 |
| 13 | Whole-genome sequencing provides insights into the genetic diversity and domestication of bitter gourd(Momordica spp.)显示文摘Bitter gourd(Momordica charantia)is a popular cultivated vegetable in Asian and African countries.To reveal the characteristics of the genomic structure,evolutionary trajectory,and genetic basis underlying the domestication of bitter gourd,we performed whole-genome sequencing of the cultivar Dali-11 and the wild small-fruited line TR and resequencing of 187 bitter gourd germplasms from 16 countries.The major gene clusters(Bi clusters)for the biosynthesis of cucurbitane triterpenoids,which confer a bitter taste,are highly conserved in cucumber,melon,and watermelon.Comparative analysis among cucurbit genomes revealed that the Bi cluster involved in cucurbitane triterpenoid biosynthesis is absent in bitter gourd.Phylogenetic analysis revealed that the TR group,including 21 bitter gourd germplasms,may belong to a new species or subspecies independent from M.charantia.Furthermore,we found that the remaining 166 M.charantia germplasms are geographically differentiated,and we identified 710,412,and 290 candidate domestication genes in the South Asia,Southeast Asia,and China populations,respectively.This study provides new insights into bitter gourd genetic diversity and domestication and will facilitate the future genomics-enabled improvement of bitter gourd. | Junjie Cui Yan Yang Shaobo Luo Le Wang Rukui Huang Qingfang Wen Xiaoxia Han Nansheng Miao Jiaowen Cheng Ziji Liu Changyuan Zhang Chengcheng Feng Haisheng Zhu Jianwen Su Xinjian Wan Fang Hu Yu Niu Xiaoming Zheng Yulan Yang Dai Shan Zhensheng Dong Weiming He Narinder P.S.Dhillon Kailin Hu | 2020 | Horticulture Research2020，7，1： | 7 |
| 14 | Soil erosion and sediment interception by check dams in a watershed for an extreme rainstorm on the Loess Plateau,China显示文摘The magnitude of soil erosion and sediment load reduction efficiency of check dams under extreme rainstorms is a long-standing concern.The current paper aims to use check dams to deduce the amount of soil erosion under extreme rainstorms in a watershed and to identify the difference in sediment interception efficiency of different types of check dams.Based on the sediment deposition at 12 check dams with 100% sediment interception efficiency and sub-catchment clustering by taking 12 damcontrolled catchments as clustering criteria,the amount of soil erosion resulting from an extreme rainstorm event on July 26,2017(named '7·26' extreme rainstorm) was estimated in the Chabagou watershed in the hill and gully region of the Loess Plateau.The differences in the sediment interception efficiency among the check dams in the watershed were analyzed according to field observations at 17 check dams.The results show that the average erosion intensity under the '7-26' extreme rainstorm was approximately 2.03×10~4 t/km^2,which was 5 times that in the second largest erosive rainfall in 2017(4.15×10~3 t/km^2) and 11-384 times that for storms in 2018(0.53×10~2 t/km^2-1.81×10~3 t/km^2).Under the '7-26' extreme rainstorm,the amount of soil erosion in the Chabagou watershed above the Caoping hydrological station was 4.20 × 106 t.The sediment interception efficiency of the check dams with drainage canals(including the destroyed check dams) and with drainage culverts was 6.48 and 39.49%,respectively.The total actual sediment amount trapped by the check dams was 1.11 × 106 t,accounting for 26.36% of the total amount of soil erosion.In contrast,3.09×106 t of sediment were input to the downstream channel,and the sediment deposition in the channel was 2.23×10~6 t,accounting for 53.15%of the total amount of soil erosion.The amount of sediment transport at the hydrological station was8.60×10~5 t.The Sediment Delivery Ratio(SDR) under the '7·26' extreme rainstorm was 0.21.The results indicated that the amount of soil erosion was huge,and the sediment interception efficiency of the check dams was greatly reduced under extreme rainstorms.It is necessary to strengthen the management and construction technology standards of check dams to improve the sediment interception efficiency and flood safety in the watershed. | Leichao Bai Nan Wang Juying Jiao Yixian Chen Bingzhe Tang Haolin Wang Yulan Chen Xiqin Yan Zhijie Wang | 2020 | International Journal of Sediment Research2020，35，4： | 7 |
| 15 | Diamond Raman laser:a promising high-beam-quality and low-thermal-effect laser显示文摘Stimulated Raman-scattering-based lasers provide an effective way to achieve wavelength conversion.However,thermally induced beam degradation is a notorious obstacle to power scaling and it also limits the applicable range where high output beam quality is needed.Considerable research efforts have been devoted to developing Raman materials,with diamond being a promising candidate to acquire wavelength-versatile,high-power,and high-quality output beam owing to its excellent thermal properties,high Raman gain coefficient,and wide transmission range.The diamond Raman resonator is usually designed as an external-cavity pumped structure,which can easily eliminate the negative thermal effects of intracavity laser crystals.Diamond Raman converters also provide an approach to improve the beam quality owing to the Raman cleanup effect.This review outlines the research status of diamond Raman lasers,including beam quality optimization,Raman conversion,thermal effects,and prospects for future development directions. | Yulan Li Jie Ding Zhenxu Bai Xuezong Yang Yuqi Li Jingling Tang Yu Zhang Yaoyao Qi Yulei Wang Zhiwei Lu | 2021 | High Power Laser Science and Engineering2021，9，3： | 7 |
| 16 | A review:applications of the phase field method in predicting microstructure and property evolution of irradiated nuclear materials显示文摘Complex microstructure changes occur in nuclear fuel and structural materials due to the extreme environments of intense irradiation and high temperature.This paper evaluates the role of the phase field method in predicting the microstructure evolution of irradiated nuclear materials and the impact on their mechanical,thermal,and magnetic properties.The paper starts with an overview of the important physical mechanisms of defect evolution and the significant gaps in simulating microstructure evolution in irradiated nuclear materials.Then,the phase field method is introduced as a powerful and predictive tool and its applications to microstructure and property evolution in irradiated nuclear materials are reviewed.The review shows that(1)Phase field models can correctly describe important phenomena such as spatial-dependent generation,migration,and recombination of defects,radiation-induced dissolution,the Soret effect,strong interfacial energy anisotropy,and elastic interaction;(2)The phase field method can qualitatively and quantitatively simulate two-dimensional and three-dimensional microstructure evolution,including radiation-induced segregation,second phase nucleation,void migration,void and gas bubble superlattice formation,interstitial loop evolution,hydrate formation,and grain growth,and(3)The Phase field method correctly predicts the relationships between microstructures and properties.The final section is dedicated to a discussion of the strengths and limitations of the phase field method,as applied to irradiation effects in nuclear materials. | Yulan Li Shenyang Hu Xin Sun Marius Stan | 2017 | npj Computational Materials2017，，1： | 6 |
| 17 | IL-17 sustains the plasma cell response via p38-mediated Bcl-xL RNA stability in lupus pathogenesis显示文摘Recent studies have demonstrated a central role for plasma cells in the development of autoimmune diseases,such as systemic lupus erythematosus(SLE).Currently,both the phenotypic features and functional regulation of autoreactive plasma cells during SLE pathogenesis remain largely unclear.In this study,we first found that a major subset of IL-17 receptor-expressing plasma cells potently produced anti-dsDNA IgG upon IL-17A(IL-17)stimulation in SLE patients and lupus mice.Using a humanized lupus mouse model,we showed that the transfer of Th17 cell-depleted PBMCs from lupus patients resulted in a significantly reduced plasma cell response and attenuated renal damage in recipient mice compared to the transfer of total SLE PBMCs.Moreover,long-term BrdU incorporation in lupus mice detected highly enriched long-lived BrdU+subsets among IL-17 receptor-expressing plasma cells.Lupus mice deficient in IL-17 or IL-17 receptor C(IL-17RC)exhibited a diminished plasma cell response and reduced autoantibody production with attenuated renal damage,while the adoptive transfer of Th17 cells triggered the plasma cell response and renal damage in IL-17-deficient lupus mice.In reconstituted chimeric mice,IL-17RC deficiency resulted in severely impaired plasma cell generation but showed no obvious effect on germinal center B cells.Further mechanistic studies revealed that IL-17 significantly promoted plasma cell survival via p38-mediated Bcl-xL transcript stabilization.Together,our findings identified a novel function of IL-17 in enhancing plasma cell survival for autoantibody production in lupus pathogenesis,which may provide new therapeutic strategies for the treatment of SLE. | Kongyang Ma Wenhan Du Fan Xiao Man Han Enyu Huang Na Peng Yuan Tang Chong Deng Lixiong Liu Yulan Chen Jingjing Li Shiwen Yuan Qin Huang Xiaoping Hong Dajun Hu Xiaoyan Cai Quan Jiang Dongzhou Liu Liwei Lu | 2021 | Cellular & Molecular Immunology2021，18，7： | 6 |
| 18 | Germination and early seedling growth of Pinus densata Mast.provenances显示文摘We studied seed germination and early seedling growth of Pinus densata to explore the range of variability within the species and to inform afforestation practices.Phenotypes were evaluated at a forest tree nursery under conditions that support Pinus yunnanensis, one of the presumed parental species of P. densata. Seeds were collected from 20 open-pollinated trees within each of eight autochthonous populations representing the natural distribution of P. densata in China to assess variation in germination traits and early seedling growth, and to examine the relationships among these traits. Results showed that seeds from all populations germinated and seedlings established successfully. There were significant differences among populations in 13 of 14 traits evaluated. Seed germination and early seedling growth were strongly related to seed size and seed weight. Bigger seeds germinated earlier and faster than small seeds, and seedling size was positively correlated with seed size. Some germination traits were strongly and significantly correlated with climatic variables associated with the provenance of the studied populations. Based on these observations, we conclude there were large, significant, and biologically important differences among P. densata populations in seed germination and seedling growth traits. The observed variability probably reflects a high degree of adaptive differentiation among populations that is likely to be relevant for future afforestation. | Yulan Xu Nianhui Cai Bin He Ruili Zhang Wei Zhao Jianfeng Mao Anan Duan Yue Li Keith Woeste | 2016 | Journal of Forestry Research2016，27，2： | 5 |
| 19 | Carbothermic reduction of vanadium titanomagnetite with the assistance of sodium carbonate显示文摘The carbothermic reduction of vanadium titanomagnetite concentrate(VTC)with the assistance of Na_(2)CO_(3)was conducted in an argon atmosphere between 1073 and 1473 K.X-ray diffraction and scanning electron microscopy were used to investigate the phase transformations during the reaction.By investigating the reaction between VTC and Na_(2)CO_(3),it was concluded that molten Na_(2)CO_(3)broke the structure of titanomagnetite by combining with the acidic oxides(Fe_(2)O_(3),TiO_(2),Al_(2)O_(3),and SiO_(2))to form a Na-rich melt and release FeO and MgO.Therefore,Na_(2)CO_(3)accelerated the reduction rate.In addition,adding Na_(2)CO_(3)also benefited the agglomeration of iron particles and the slag–metal separation by decreasing the viscosity of the slag.Thus,Na_(2)CO_(3)assisted carbothermic reduction is a promising method for treating VTC at low temperatures. | Luming Chen Yulan Zhen Guohua Zhang Desheng Chen Lina Wang Hongxin Zhao Fancheng Meng Tao Qi | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，2： | 5 |
| 20 | Long non-coding RNA in liver metabolism and disease:Current status显示文摘Long non-coding RNAs(lncRNAs)are comprised of RNA transcripts exceeding 200 nucleotides in length but lacking identifiable open reading frames(with rare exceptions).Herein,we highlight emerging evidence demonstrating that lncRNAs are critical regulators of liver metabolic function and diseases.We summarize current knowledges about dysregulated lncRNAs and outline the underlying molecular mechanisms by which lncRNAs control hepatic lipid ad glucose metabolism,as well as cholestatic liver disease.Liver-specific triglyceride regulator(lncLSTR),Lnc18q22.2,steroid RNA activator(SRA),highly upregulated in liver cancer(HULC),metastasis associated in lung adenocarcinoma transcript 1(MALAT1),liver glucokinase repressor(lncLGR),maternally expressed gene 3(MEG3),and H19,lncHR1,lnc-HC,apolipoprotein A1 antisense transcript(APOA1-AS),DYNLRB2-2,and LXR-induced sequence(LeXis)are included in the discussion. | Yulan Zhao Jianguo Wu Suthat Liangpunsakul Li Wang | 2017 | Liver Research2017，1，3： | 5 |
