| 1 | Influence of genotypes and environmental factors on leaf triterpenoid content and growth of Cyclocarya paliurus显示文摘Cyclocarya paliurus, an economically valuable tree species, has traditionally been used as a nutraceutical food or medicine in China. However, limited information is available on its genotype selection and cultivation under a wide range of environmental conditions for growth and targeted health-promoting substances. We studied the effects of genotype and environment, and their interaction on leaf triterpenoid content and tree growth for 12 genotypes of C. paliurus grown at four sites. We quantified the correlation between leaf triterpenoid accumulation and tree growth. The contents of cyclocaric acid B, cyclocarioside I, and arjunolic acid ranged from 0.06 to 3.89, 0 to 3.71, and 0.65 to 8.86 mg g^-1, respectively. Three individual triterpenoids were primarily influenced by genotype (variation ranged from 53.7 to 68.0%), while environment accounted for most of the variation in total triterpenoid content and tree growth (71.3–89.5%). Most tested environmental parameters were significantly correlated to total triterpenoid content, but not to the contents of the individual triterpenoids measured. Growth in tree height and diameter at breast height were significantly negatively correlated with total triterpenoid content but were non-significantly correlated with individual triterpenoid contents. We conclude that genotypic selection, manipulation of environmental conditions, and implementation of appropriate silvicultural operations would be important strategies for increasing the accumulation of health-promoting phytochemicals. | Bo Deng Shengzuo Fang Xulan Shang Xiangxiang Fu Wanxia Yang | 2019 | Journal of Forestry Research2019，30，3： | 7 |
| 2 | Natural variations in flavonoids and triterpenoids of Cyclocarya paliurus leaves显示文摘Cyclocarya paliurus is widely distributed in subtropical areas of China.Secondary metabolites in the leaves,including flavonoids and triterpenoids,provide protection against diseases such as hyperlipidemia,diabetes,hypertension,and hypoimmunity.In this study,343 C.paliurus leaves were collected from 32 distinct populations covering most of the main distribution,to deduce the response of flavonoids and triterpenoids to seven environmental factors.Principal component analysis was performed using seven flavonoid and six triterpenoid compounds.The results show that altitude,latitude,and longitude significantly contributed to variations in total flavonoid and triterpenoid contents.In addition,the interaction of these metabolites was extensively correlated with environment changes,and therefore should be considered during selection and cultivation. | Caowen Sun Xulan Shang Haifen Ding Yanni Cao Shengzuo Fang | 2021 | Journal of Forestry Research2021，32，2： | 6 |
| 3 | Screening of the Indoor Plants for Removing Formaldehyde显示文摘[Objective]The research aimed to screen out the best ornamental houseplants to remove formaldehyde from indoor air through deposition velocity and to explore the pathways of plants for formaldehyde removal. [Method]Fifty-three indoor ornamental plant species were experimented in series of sealed chambers (volumes of 0. 096m3 ) by formaldehyde fumigation with the internal concentration of (1 ±0.1) mg/L in this study. The removal efficiency of formaldehyde was assessed by the uptake fluxes and the deposition velocity of formaldehyde. [Result]Six species of indoor plants ( Hedera helix,Ficus elastica Roxb. ex Hornem,Nephrolepis exaltata cv. Bostoniensis,Begonia evansiana,Mentha canadensis L. and Adiantum capillus-veneris Linn. ) with high formaldehyde removal efficiency were firstly screened out. Significance analysis of the deposition velocity by Statistical Program for Social Sciences ( SPSS) presented that tested plants belonging to the same genera or family had similar ability to remove formaldehyde pollution. The diurnal variations of deposition velocity for the six plants were then tested further. The results showed that four of them, including Ficus elastica Roxb. ex Hornem,Nephrolepis exaltata cv. Bostoniensis,Mentha canadensis L. and Adiantum capillus-veneris Linn. removed formaldehyde mainly by leaves surface adsorption,while Begonia evansiana and Hedera helix by stomatal uptake. [Conclusion] Begonia evansiana and Hedera helix are the most efficient indoor plants among the 53 species studied for phytoremediation of the air formaldehyde pollution. | Shujuan Zhang Yaotang Huang Zizhao Xie Xulan Zhang | 2013 | Meteorological and Environmental Research2013，4，2： | 3 |
| 4 | Atomically dispersed Co-Cu alloy reconstructed from metalorganic framework to promote electrochemical CO_(2)methanation显示文摘Electroreduction of carbon dioxide into value-added fuels or chemicals using renewable energy helps to effectively reduce carbon dioxide emission and alleviate the greenhouse effect while storing intermittent energies.Due to the existing infrastructure of global natural gas utilization and distribution,methane produced in such a green route attracts wide interests.However,limited success has been witnessed in the practical application of catalysts imparting satisfactory methane activity and selectivity.Herein,we report the fabrication of an atomically dispersed Co-Cu alloy through the reconstruction of trace-Co doped Cu metalorganic framework.This catalyst exhibits a methane Faradaic efficiency of 60%±1%with the corresponding partial current density of 303±5 mA·cm^(−2).Operando X-ray adsorption spectroscopy and attenuated-total-reflection surface enhanced infrared spectroscopy unravel that the introduction of atomically dispersed Co in Cu favors*CO protonation via enhancing surface water activation,and suppresses C−C coupling by reducing*CO coverage,thereby leading to high methane selectivity. | Hao Sun Ling Lin Wei Hua Xulan Xie Qiaoqiao Mu Kun Feng Jun Zhong Fenglei Lyu Zhao Deng Yang Peng | 2023 | Nano Research2023，16，3： | 1 |

| 7 | Whole-genome Duplication Reshaped Adaptive Evolution in A Relict Plant Species,Cyclocarya paliurus显示文摘Cyclocarya paliurus is a relict plant species that survived the last glacial period and shows a population expansion recently.Its leaves have been traditionally used to treat obesity and diabetes with the well-known active ingredient cyclocaric acid B.Here,we presented three C.paliurus genomes from two diploids with different flower morphs and one haplotype-resolved tetraploid assembly.Comparative genomic analysis revealed two rounds of recent whole-genome duplication events and identified 691 genes with dosage effects that likely contribute to adaptive evolution through enhanced photosynthesis and increased accumulation of triterpenoids.Resequencing analysis of 45 C.paliurus individuals uncovered two bottlenecks,consistent with the known events of environmental changes,and many selectively swept genes involved in critical biological functions,including plant defense and secondary metabolite biosynthesis.We also proposed the biosynthesis pathway of cyclocaric acid B based on multi-omics data and identified key genes,in particular gibberellinrelated genes,associated with the heterodichogamy in C.paliurus species.Our study sheds light on evolutionary history of C.paliurus and provides genomic resources to study the medicinal herbs. | Yinquan Qu Xulan Shang Ziyan Zeng Yanhao Yu Guoliang Bian Wenling Wang Li Liu Li Tian Shengcheng Zhang Qian Wang Dejin Xie Xuequn Chen Zhenyang Liao Yibin Wang Jian Qin Wanxia Yang Caowen Sun Xiangxiang Fu Xingtan Zhang Shengzuo Fang | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 1 |

| 9 | Roles of the fibroblast growth factor signal transduction system in tissue injury repair显示文摘Following injury,tissue autonomously initiates a complex repair process,resulting in either partial recovery or regeneration of tissue architecture and function in most organisms.Both the repair and regeneration processes are highly coordinated by a hierarchy of interplay among signal transduction pathways initiated by different growth factors,cytokines and other signaling molecules under normal conditions.However,under chronic traumatic or pathological conditions,the reparative or regenerative process of most tissues in different organs can lose control to different extents,leading to random,incomplete or even flawed cell and tissue reconstitution and thus often partial restoration of the original structure and function,accompanied by the development of fibrosis,scarring or even pathogenesis that could cause organ failure and death of the organism.Ample evidence suggests that the various combinatorial fibroblast growth factor(FGF)and receptor signal transduction systems play prominent roles in injury repair and the remodeling of adult tissues in addition to embryonic development and regulation of metabolic homeostasis.In this review,we attempt to provide a brief update on our current understanding of the roles,the underlying mechanisms and clinical application of FGFs in tissue injury repair. | Keyang Chen Zhiheng Rao Siyang Dong Yajing Chen Xulan Wang Yongde Luo Fanghua Gong Xiaokun Li | 2022 | Burns & Trauma2022，10，1： | 1 |

| 11 | Porous Fe-Mn-O nanocomposites:Synthesis and supercapacitor electrode application显示文摘Transition metal oxide micro-/nanostructures demonstrate high potential applications in energy storage devices. Here, we report a facile synthesis of highly homogeneous oxide composites with porous structure via a coordination polymer precursor, which was prepared with the assistance of tartaric acid.The typical product, Fe-Mn-O composite was demonstrated here. The obtained Fe-Mn-O product was systemically characterized by X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, elemental mapping analysis, and X-ray photoelectron spectroscopy. It was demonstrated that the Fe-Mn-O nanocomposite shows interconnected porous structure, in which iron,manganese, and oxygen are uniformly distributed. In addition, the Fe-Mn-O nanocomposite was then fabricated as capacitor electrodes. Operating in an aqueous neutral solution, the Fe-Mn-O composite electrodes showed an wide working potential window from 0.2 to 1.0 V(vs. SCE), and a specific capacitance of 86.7 Fg^(-1)or 0.4 Fcm^(-2)at a constant current density of 1 Ag^(-1)with good cycle life. This study offers a new precursor approach to prepare porous metal oxide composites, which would be applied in energy-storage/conversion devices, catalysts, sensors, and so on. | Guoxing Zhu Jing Yang Yuanjun Liu Xulan Xie Zhenyuan Ji Jinxiu Yin Xiaoping Shen | 2016 | Progress in Natural Science:Materials International2016，26，3： | 0 |
| 12 | Hydroxylated metal–organic-layer nanocages anchoring single atomic cobalt sites for robust photocatalytic CO_(2) reduction显示文摘Assembly of two-dimensional(2D)metal–organic layers(MOLs)based on the hard and soft acid–base theorem represents an exquisite strategy for the construction of photocatalytic platforms in virtue of the highly exposed active sites,much improved mass transport,and greatly elevated stability.Herein,nanocages composed of MOLs are produced for the first time through a cosolvent approach utilizing zirconium-based UiO-66-(OH)2 as the structural precursor.To endow the catalytic activity for CO_(2) conversion,single atomic Co^(2+)sites are appended to the Zr-oxo nodes of the MOL cages,demonstrating a remarkable CO yield of 7.74 mmol·g^(-1)·h^(-1) and operational stability of 97.1%product retention after five repeated cycles.Such an outstanding photocatalytic performance is mainly attributed to the unique nanocage morphology comprising enormous 2D nanosheets for augmented Co^(2+)exposure and the abundant surface hydroxyl groups for local CO_(2) enrichment.This work underlines the tailoring of both metal–organic framework(MOF)morphology and functionality to boost the turnover rate of photocatalytic CO_(2) reduction reaction(CO_(2)RR). | Weiyi Pan Zhihe Wei Yanhui Su Yuebin Lian Zhangyi Zheng Huihong Yuan Yongze Qin Xulan Xie Qianqian Bai Zhenyang Jiao Wei Hua Jinzhou Chen Wenjun Yang Zhao Deng Yang Peng | 2024 | Nano Research2024，17，4： | 0 |
| 13 | Design of experiments unravels insights into selective ethylene or methane production on evaporated Cu catalysts显示文摘As a highly tempting technology to close the carbon cycle,electrochemical CO_(2)reduction calls for the development of highly efficient and durable electrocatalysts.In the current study,Design of Experiments utilizing the response surface method is exploited to predict the optimal process variables for preparing high-performance Cu catalysts,unraveling that the selectivity towards methane or ethylene can be simply modulated by varying the evaporation parameters,among which the Cu film thickness is the most pivotal factor to determine the product selectivity.The predicted optimal catalyst with a low Cu thickness affords a high methane Faradaic efficiency of 70.6%at the partial current density of 211.8 m A cm^(-2),whereas that of a high Cu thickness achieves a high ethylene selectivity of 66.8%at267.2 m A cm^(-2)in the flow cell.Further structure-performance correlation and in-situ electrospectroscopic measurements attribute the high methane selectivity to isolated Cu clusters with low packing density and monotonous lattice structure,and the high ethylene efficiency to coalesced Cu nanoparticles with rich grain boundaries and lattice defects.The high Cu packing density and crystallographic diversity is of essence to promoting C–C coupling by stabilizing*CO and suppressing*H coverage on the catalyst surface.This work highlights the implementation of scientific and mathematic methods to uncover optimal catalysts and mechanistic understandings toward selective electrochemical CO_(2)reduction. | Jian Cheng Yuqing Bai Zhihe Wei Qiaoqiao Mu Hao Sun Ling Lin Long Xiao Xulan Xie Zhao Deng Yang Peng | 2022 | Journal of Energy Chemistry2022，，12： | 0 |
| 14 | Capability of cation exchange technology to remove proven N-nitrosodimethylamine precursors显示文摘N-nitrosodimethylamine(NDMA) precursors consist of a positively charged dimethylamine group and a non-polar moiety, which inspired us to develop a targeted cation exchange technology to remove NDMA precursors. In this study, we tested the removal of two representative NDMA precursors, dimethylamine(DMA) and ranitidine(RNTD), by strong acidic cation exchange resin. The results showed that pH greatly affected the exchange efficiency, with high removal(DMA > 78% and RNTD > 94%) observed at pH < pk_a-1 when the molar ratio of exchange capacity to precursor was 4. The exchange order was obtained as follows: Ca^(2+)> Mg^(2+)> RNTD^+> K^+> DMA^+> NH_4^+> Na^+. The partition coefficient of DMA^+to Na^+was 1.41 ± 0.26, while that of RNTD^+to Na^+was 12.1 ± 1.9. The pseudo second-order equation fitted the cation exchange kinetics well. Bivalent inorganic cations such as Ca^(2+)were found to have a notable effect on NA precursor removal in softening column test. Besides DMA and RNTD, cation exchange process also worked well for removing other 7 model NDMA precursors. Overall, NDMA precursor removal can be an added benefit of making use of cation exchange water softening processes. | Shixiang Li Xulan Zhang Er Bei Huihui Yue Pengfei Lin Jun Wang Xiaojian Zhang Chao Chen | 2017 | Journal of Environmental Sciences2017，29，8： | 0 |
| 15 | Thermo-Mechanical Analysis of the Sealing Performance of a Diesel-Engine Cylinder Gasket显示文摘Taking the combustor composite structure of a high-strength diesel engine as the main research object,dedicated tests have been conducted to verify the accuracy of three distinct cylinder gasket pressure simulation models.Using the measured cylinder gasket compression rebound curve,a gasket unit has been designed and manufactured.For this unit,the influence of the bolt pretension,cylinder body and cylinder head material on gasket sealing pressure has been investigated systematically in conditions of thermo-mechanical coupling.The results show that the bolt pretension force is one of the most important factors affecting the cylinder gasket sealing pressure.The change of the body material has little effect on this pressure.The cylinder gasket seal pressure decreases progressively with the reduction of the elastic module of the cylinder head material. | Xulan Wang Zezhong Chen Changzhen Liu Wei Ren Bo Wu Shude Ji Xiaofei Chen Shijie Wen Yonggang Hao | 2021 | Fluid Dynamics & Materials Processing2021，17，4： | 0 |
| 16 | Measurement of serum granulocyte colonystimulating factor levels in patients with different phase of infection显示文摘Objective: To detect the serum granulocyte colony-stimulating factor (G-CSF) levels between the patients with frequently repeated infection (repeaters) and others (non-repeaters) in different phase of infection. Methods: An enzyme-linked immunosorbent assay (ELISA) method was used to detect serum G-CSF levels in 50 cases (32 non-repeaters and 18 repeaters) with acute phase of infection. Serum G-CSF levels were detected in recovery phase in 10 cases. Results: Serum G-CSF levels were significantly higher (1429.97±506.43ng/L) in 32 non-repeaters with acute infection. There was a positive correlation between white blood cell count (WBC) and serum G-CSF level (r =0. 396, P <0.05). There was also a positive correlation between absolute neutrophil count (ANC) and serum G-CSF level (r=0.346,P<0,05). Serum G-CSF levels were higher (98.62 -+56.40ng/L) in 18 repeaters with acute infection, It was showed that serum G-CSF levels were significantly higher in non-repeaters than in repeaters with acute phase of infection ( P <0. 001 ). In the meanwhile, the body temperature was significantly higher in non-repeaters than in repeaters with acute infection (37.95±0.14℃ rs 36.91±0.13℃ ,P <0.001), There were no significant differences in age, WBC, ANC, type of bacterial, liver function and renal function (P > 0.05). Serum G-CSF levels in recovery phase of the two groups were below the sensitivity of the assay ( < 60 ng/L), Conlusion: It is suggested that application of recombinant G-CSF may be useful for the patients with repeated infection, | WUWen HUJiong ZHAOWei-li YANHua TANGWei XULan SHIGuang-ning SHENZhi-xiang SUNGuan-lin WANGZhen-yi | 2005 | 上海第二医科大学学报2005，25，7： | 0 |
