| 1 | Accumulation of soil organic carbon during natural restoration of desertified grassland in China's Horqin Sandy Land显示文摘China's Horqin Sandy Land,a formerly lush grassland,has experienced extensive desertification that caused considerable carbon(C) losses from the plant-soil system.Natural restoration through grazing exclusion is a widely suggested option to sequester C and to restore degraded land.In a desertified grassland,we investigated the C accumulation in the total and light fractions of the soil organic matter from 2005 to 2013 during natural restoration.To a depth of 20 cm,the light fraction organic carbon(LFOC) storage increased by 221 g C/m2(84%) and the total soil organic carbon(SOC) storage increased by 435 g C/m2(55%).The light fraction dry matter content represented a small proportion of the total soil mass(ranging from 0.74% in 2005 to 1.39% in 2013),but the proportion of total SOC storage accounted for by LFOC was remarkable(ranging from 33% to 40%).The C sequestration averaged 28 g C/(m2·a) for LFOC and 54 g C/(m2·a) for total SOC.The total SOC was strongly and significantly positively linearly related to the light fraction dry matter content and the proportions of fine sand and silt+clay.The light fraction organic matter played a major role in total SOC sequestration.Our results suggest that grazing exclusion can restore desertified grassland and has a high potential for sequestering SOC in the semiarid Horqin Sandy Land. | YuQiang LI XueYong ZHAO FengXia ZHANG Tala AWADA ShaoKun WANG HaLin ZHAO TongHui ZHANG YuLin LI | 2015 | Journal of Arid Land2015，7，3： | 21 |
| 2 | N and P resorption in a pioneer shrub(Artemisia halodendron) inhabiting severely desertified lands of Northern China显示文摘Nutrient resorption is an important conservation mechanism for plants to overcome nutrient limitation in the less fertile area of desertified land.In the semi-arid Horqin Sandy Land of Northern China,the shrub Artemisia halodendron usually colonizes into the bare ground of severely desertified land as a pioneer species.It is,therefore,expected that A.halodendron will be less dependent on current nutrient uptake through efficient and proficient resorption of nutrients.In this study,we found that averaged nitrogen(N)and phosphorus(P)concentrations in senesced leaves significantly varied from 12.3 and 1.2 mg/g in the shifting sand dune to 15.9 and 1.9 mg/g in the fixed sand dune,respectively,suggesting that foliar N and P resorption of A.halodendron were more proficient in the shifting sand dune.In particular,positive relationships between nutrient concentrations in senesced leaves and soil nutrient availability indicate that A.halodendron in infertile habitats is more likely to manage with a low level of nutrients in senesced leaves,giving this species an advantage in infertile soil.Moreover,foliar N-and P-resorption efficiencies and proficiencies showed limited inter-annual variability although annual precipitation varied greatly among 2007–2009.However,N and P resorption of A.halodendron were not more efficient and proficient than those previously reported for other shrubs,indicating that the pioneer shrub in sand dune environments does not rely more heavily than other plants on the process of resorption to conserve nutrients.Incomplete resorption of nutrients in A.halodendron suggests that senesced-leaf fall would return litter with high quality to the soil,and thereby would indirectly improve soil nutrient availability.The restoration of desertified land,therefore,may be accelerated after A.halodendron pioneers into shifting sand dunes. | YuLin LI Chen JING Wei MAO Duo CUI XinYuan WANG XueYong ZHAO | 2014 | Journal of Arid Land2014，6，2： | 11 |
| 3 | Impending HRT wave precursors to the Wenchuan M_s8.0 earthquake and methods of earthquake impending prediction by using HRT wave显示文摘We deployed four geo-electric monitoring stations in Sichuan and Yunnan provinces from 2004, using the new generation of equipment (PS-100) and technologies to capture the HRT wave earthquake precursor. Before the Wenchuan Ms8.0 earthquake, we recorded the HRT wave precursor at the only operating station in Hongge (HG, Δ=465 km) and found that significant impending signal had been recorded at the station in the early morning ( 0―5 am) of 12th of May, 2008. The precursor for this earthquake is consistent with precursors recorded for other strong earthquakes. The measured physical properties (geo-resistivity and telluric-current) show tidal wave period oscillations from several days to several months before the earthquakes and the amplitude of such HT oscillation increases significantly towards the occurrence of an earthquake. These HT and RT waves from the epicenter have a causal relationship with the earthquakes that happened several days later. The arrival time of two RT waves is proportional to the distance from the station to the epicenter. The estimated natural decay of the amplitude is correlated with the natural period (T0) of the earthquake fault, which is proportional to the fault length. From this relationship, we can predict the earthquake magnitude. For magnitude 6―9 earthquakes, the natural period is about 1―6 hours. Such oscillation comes from the epicenter area and they can propagate several thousand kilometers in the Earth's crust. Before a strong earthquake in the shallow crust, the conductive pore fluid will experience major changes before the fault rapture. Such fluid change will emit an oscillation in the pore fluid pressure. This is the mechanism for the HRT wave generation. Since the China Earthquake Administration funded the HRT wave short-term earth-quake prediction project in 2003, the first record of HRT precursor wave has been recorded from the 2004-12-26 Sumatra Mw9.0 earthquake with the largest epicentre distance Δ=2900 km. Thereafter, we have captured HRT waves from more than twenty strong earthquakes, which are well-matched and show repeatability, consistency and regularity. All our observation with the HRT waves demonstrate that HRT wave precursors to earthquakes indeed exist. Strong earthquakes can be predicted and short-term and impending earthquake prediction is achievable in the very near future. From all the observations, including the ones at HG station from Wenchuan Ms8.0 earthquake, we conclude that using HRT wave to predict earthquakes is feasible. | QIAN FuYe ZHAO BiRu QIAN Wei ZHAO Jian HE ShiGen ZHANG HongKui LI ShiYu LI ShaoKun YAN GuLiang WANG ChengMin SUN ZhenKai ZHANG DongNing LU Jun ZHANG Ping YANG GuoJun SUN JiaLin GUO ChunSheng TANG YuXiong XU JianMing XIA KunTao JU Hang YIN BangHong LI Ming YANG DongSheng QI WeiLuo HE TaiMing GUAN HuaPing ZHAO YuLin | 2009 | Science China Earth Sciences2009，52，10： | 8 |
| 4 | Changes in T lymphocyte subsets after severe traumatic brain injury显示文摘BACKGROUND: Besides local changes of cranial parenchymal cells, hemorrhage, etc., severe traumatic brain injuries also cause the changes of total body fluid and various functions, and the changes of lymphocytes and T lymphocyte subsets should be paid more attention to. OBJECTIVE: To reveal the changing laws of T lymphocyte subsets after severe traumatic brain injury, and compare with mild to moderate brain injury. DESIGN: A comparative observation. SETTINGS: Department of Neurosurgery, Longgang District Buji People's Hospital of Shenzhen City; Central Laboratory of Shenzhen Hospital of Prevention and Cure for Chronic Disease. PARTICIPANTS: All the subjects were selected from the Department of Neurosurgery, Longgang District Buji People's Hospital of Shenzhen City from August 2002 to August 2005. Thirty patients with severe brain injury, whose Glasgow coma score (GCS) was ≤ 8 points, were taken as the experimental group, including 21 males and 9 females, aging 16–62 years. Meanwhile, 30 patients with mild traumatic brain injury were taken as the control group (GCS ranged 14–15 points), including 18 males and 12 females, aging 15–58 years. All the subjects were in admission at 6 hours after injury, without disease of major organs before injury. Informed consents were obtained from all the patients or their relatives. METHODS: ① The T lymphocytes and the subsets in peripheral blood were detected with immunofluorescent tricolor flow cytometry at 1, 3, 7 and 14 days after injury in both groups. ② The conditions of pulmonary infections were observed at 4 days after injury. The differences of measurement data were compared with the t test. MAIN OUTCOME MEASURES: Changes of T lymphocytes subsets at 1–14 days after severe and mild or moderate traumatic injury. RESULTS: Finally, 28 and 25 patients with mild to moderate traumatic brain injury, whereas 25 and 21 patients with severe traumatic brain injury were analyzed at 7 and 14 days respectively, and the missed ones died due to the development of disease. ① Changes of T lymphocyte subsets: At 1 and 3 days after injury, CD3, CD4, CD8, CD4/CD8 began to decrease, whereas CD8 increased in the experimental group, which were very significantly different from those in the control group (t =2.77–3.26, P < 0.01), and began to recover at 7 days, which were significantly different from those in the control group (t = 2.06–2.24, P < 0.05), and generally recovered to the normal levels at 14 days (P > 0.05). ② Conditions of pulmonary infections: At 4 days after injury, the rate of pulmonary infection was significantly different between the experimental group and control group [73% (22/30), 0, χ2=37.29, P < 0.01]. CONCLUSION: Patients with severe traumatic brain injury suffer from damages of cellular immune function at early period (within 7 days), and they are easily to be accompanied by pulmonary infections. | Yulu Miao Mingxia Zhang Yulin Nie Wan Zhao Bin Huang Zhengming Jiang Shaoxiong Yu Zhibin Huang Hongjin Fu | 2007 | Neural Regeneration Research2007，2，2： | 7 |
| 5 | The calcium-dependent protein kinase ZmCDPK7 functions in heat-stress tolerance in maize显示文摘Global warming poses a serious threat to crops.Calcium-dependent protein kinases(CDPKs)/CPKs play vital roles in plant stress responses,but their exact roles in plant thermotolerance remains elusive.Here,we explored the roles of heat-induced ZmCDPK7 in thermotolerance in maize.ZmCDPK7-overexpressing maize plants displayed higher thermotolerance,photosynthetic rates,and antioxidant enzyme activity but lower H2 O2 and malondialdehyde(MDA)contents than wild-type plants under heat stress.ZmCDPK7-knockdown plants displayed the opposite patterns.ZmCDPK7 is attached to the plasma membrane but can translocate to the cytosol under heat stress.ZmCDPK7 interacts with the small heat shock protein sHSP17.4,phosphorylates sHSP17.4 at Ser-44 and the respiratory burst oxidase homolog RBOHB at Ser-99,and up regulates their expression.Site-directed mutagenesis of sHSP17.4 to generate a Ser-44-Ala substitution reduced ZmCDPK7’s enhancement of catalase activity but enhanced ZmCDPK7’s suppression of MDA accumulation in heat-stressed maize protoplasts.sHSP17.4,ZmCDPK7,and RBOHB were less strongly upregulated in response to heat stress in the abscisic acid-deficient mutant vp5 versus the wild type.Pretreatment with an RBOH inhibitor suppressed sHSP17.4 and ZmCDPK7 expression.Therefore,abscisic acid-induced ZmCDPK7 functions both upstream and downstream of RBOH and participates in thermotolerance in maize by mediating the phosphorylation of sHSP17.4,which might be essential for its chaperone function. | Yulong Zhao Hanwei Du Yankai Wang Huali Wang Shaoyu Yang Chaohai Li Ning Chen Hao Yang Yihao Zhang Yulin Zhu Luyao Yang Xiuli Hu | 2021 | Journal of Integrative Plant Biology2021，63，3： | 6 |
| 6 | Twin structure of the lath martensite in low carbon steel显示文摘It has been well accepted that the martensites in quenched carbon steels exhibit two typical morphologies which are closely dependent on the carbon content, i.e. lath martensite in low carbon steels and lenticular martensite in high carbon steels. Based on conventional belief, the lath martensites in low carbon steels are with high density dislocations as the substructure, in contrast to twin substructure in lenticular high carbon martensite. In the present work, an intensive transmission electron microscopy investigation was made to characterize the microstructures of the lath martensite in a low carbon steel of 0.2 wt%C. It was found that lots of lath martensites consist of twin as their substructure, rather than high density dislocations. In addition, nanoscale precipitates cohering with ferrite matrix were found at the twin interfaces. The orientation relationships between the precipitates and the ferrite matrix are in good agreement with that of primitive hexagonal ω phase in titanium alloys and other bcc metals or alloys. | Pan Zhang Yulin Chen Wenlong Xiao Dehai Ping Xinqing Zhao | 2016 | Progress in Natural Science:Materials International2016，26，2： | 6 |
| 7 | TMEM43-S358L mutation enhances NF-κBTGFp signal cascade in arrhythmogenic right ventricular dysplasia/cardiomyopathy显示文摘Arrhythmogenic right ventricular dysplasia/cardiomyopathy(ARVD/C)is a genetic cardiac muscle disease that accounts for approximately 30%sudden cardiac death in young adults.The Ser358Leu mutation of transmembrane protein 43(TMEM43)was commonly identified in the patients of highly lethal and fully penetrant ARVD subtype,ARVD5.Here,we generated TMEM43 S358L mouse to explore the underlying mechanism.This mouse strain showed the classic patholo.gies of ARVD patients,including structural abnormalities and cardiac fibrofatty.TMEM43 S358L mutation led to hyper-activated nuclear factor kB(NFkB)activation in heart tissues and primary cardiomy.ocyte cells.Importantly,this hyper activation of NF-κB directly drove the expression of pro-fibrotic gene,transforming growth factor beta(TGFβ),and enhanced downstream signal,indicating that TMEM43 S358L mutation up-regulates NF-κB-TGFβ signal cascade during ARVD cardiac fibrosis.Our study partially reveals the regulatory mechanism of ARVD development. | Guoxing Zheng Changying Jiang Yulin Li Dandan Yang Youcai Ma Bing Zhang Xuan Li Pei Zhang Xiaoyu Hu Xueqiang Zhao Jie Du Xin Lin | 2019 | Protein & Cell2019，10，2： | 5 |
| 8 | Targeting β-secretase with RNAi in neural stem cells for Alzheimer's disease therapy显示文摘There are several major pathological changes in Alzheimer's disease,including apoptosis of cholinergic neurons,overactivity or overexpression of β-site amyloid precursor protein cleaving enzyme 1(BACE1) and inflammation.In this study,we synthesized a 19-nt oligonucleotide targeting BACE1,the key enzyme in amyloid beta protein(Aβ) production,and introduced it into the pSilenCircle vector to construct a short hairpin(shRNA) expression plasmid against the BACE1 gene.We transfected this vector into C17.2 neural stem cells and primary neural stem cells,resulting in downregulation of the BACE1 gene,which in turn induced a considerable reduction in reducing Aβ protein production.We anticipate that this technique combining cell transplantation and gene therapy will open up novel therapeutic avenues for Alzheimer's disease,particularly because it can be used to simultaneously target several pathogenetic changes in the disease. | Zhonghua Liu Shengliang Li Zibin Liang Yan Zhao Yulin Zhang Yaqi Yang Minjuan Wang Feng Li | 2013 | Neural Regeneration Research2013，8，33： | 4 |
| 9 | Mutant p53 increases exosome-mediated transfer of mi R-21-3p and mi R-769-3p to promote pulmonary metastasis显示文摘Objective: Tumor metastasis is a complex, multistep process that depends on tumor cells and their communication with the tumor microenvironment. A p53 gain-of-function mutant has been shown to enhance the tumorigenesis, invasion, and metastasis abilities of tumor cells. This study aimed to investigate the roles of p53 R273 H mutation in the tumor microenvironment.Methods: The in vitro and in vivo effects of the p53 R273 H mutant on the invasion and metastasis of HCT116 cells were investigated. Exosomes from wild-type and HCT116-TP53(R273 H) cells were cocultured with mouse embryonic fibroblasts(MEFs). The roles of differentially expressed exosomal micro RNAs identified by microarray analysis were investigated. The functions of the p53 R273 H mutant in tumor cells were also investigated via gene expression microarray and quantitative polymerase chain reaction(q PCR) analyses.Results: Introducing p53 R273 H mutant into HCT116 cells significantly potentiated pulmonary metastasis in vivo. In the presence of exosomes derived from HCT116-TP53(R273 H) cells, the exosomes were taken up by MEFs and became activated. Microarray analysis showed that the p53 R273 H mutation increased the exosomal levels of mi R-21-3 p and mi R-769-3 p. Intriguingly, in clinical samples, mi R-21-3 p and mi R-769-3 p levels were significantly higher in patients with a p53 mutation than in those without this mutation. Furthermore, both mi R-21-3 p and mi R-769-3 p activated fibroblasts and exerted a synergistic effect via their target genes on the transforming growth factor-β(TGF-β)/Smad signaling pathway. The activated fibroblasts excreted cytokine TGF-β and may have reciprocally induced cancer cells to undergo epithelial-mesenchymal transition(EMT). Indeed, HCT116-TP53(R273 H) cells showed increased expression of ZEB1 and SNAI2 and decreased transcription of several cell adhesion molecules.Conclusions: The mutant p53-exosomal mi R-21-3 p/mi R-769-3 p-fibroblast-cytokine circuit appears to be responsible for communication between tumor and stromal cells, with exosomal mi RNAs acting as a bridge. mi R-21-3 p and mi R-769-3 p are potential predictive markers of pulmonary metastasis and candidate targets for therapeutic interventions. | Qiang Ju Lina Zhao Jiajia Gao Lanping Zhou Yang Xu Yulin Sun Xiaohang Zhao | 2019 | Chinese Journal of Cancer Research2019，31，3： | 4 |
| 10 | Allometric response of perennial Pennisetum centrasiaticum Tzvel to nutrient and water limitation in the Horqin Sand Land of China显示文摘Optimal partitioning theory(OPT)suggests that plants should allocate relatively more biomass to the organs that acquire the most limited resources.The assumption of this theory is that plants trade off the biomass allocation between leaves,stems and roots.However,variations in biomass allocation among plant parts can also occur as a plant grows in size.As an alternative approach,allometric biomass partitioning theory(APT)asserts that plants should trade off their biomass between roots,stems and leaves.This approach can minimize bias when comparing biomass allocation patterns by accounting for plant size in the analysis.We analyzed the biomass allocation strategy of perennial Pennisetum centrasiaticum Tzvel in the Horqin Sand Land of northern China by treating samples with different availabilities of soil nutrients and water,adding snow in winter and water in summer.We hypothesized that P.centrasiaticum alters its pattern of biomass allocation strategy in response to different levels of soil water content and soil nitrogen content.We used standardized major axis(SMA)to analyze the allometric relationship(slope)and intercept between biomass traits(root,stem,leaf and total biomass)of nitrogen/water treatments.Taking plant size into consideration,no allometric relationships between different organs were significantly affected by differing soil water and soil nitrogen levels,while the biomass allocation strategy of P.centrasiaticum was affected by soil water levels,but not by soil nitrogen levels.The plasticity of roots,leaves and root/shoot ratios was‘true’in response to fluctuations in soil water content,but the plasticity of stems was consistent for trade-offs between the effects of water and plant size.Plants allocated relatively more biomass to roots and less to leaves when snow was added in winter.A similar trend was observed when water was added in summer.The plasticity of roots,stems and leaves was a function of plant size,and remained unchanged in response to different soil nitrogen levels. | Wei MAO TongHui ZHANG YuLin LI XueYong ZHAO YingXin HUANG | 2012 | Journal of Arid Land2012，4，2： | 4 |
| 11 | Comparison of soil physico-chemical properties under different land-use and cover types in northeastern China's Horqin Sandy Land显示文摘The Horqin Sandy Land of northeastern China was originally a grassland with plenty of water and lush vegetation dominated by palatable grass species along with sparsely scattered woody species. However, it has experienced severe desertification in recent decades due to its fragile ecology together with inappropriate human activities. Currently, the landscape of the Horqin Sandy Land is dominated by irrigated croplands and sand dunes with different degrees of vegetation cover, as the region has become the most important part of the semiarid agro-pastoral ecotone of northern China. In this study, we compared soil physical and chemical properties under different land-use and cover types(irrigated cropland, rainfed cropland, sandy grassland, fixed dunes, and mobile dunes). We found that soil particle size distribution; organic C, total N, and total mineral element, microelement, and available microelement and nutrient contents; p H; CEC; and bulk density differed significantly among the land-use and cover types. In general, soil quality was highest in the cropland, intermediate in the sandy grassland, and lowest in the dunes. The most important soil quality attribute, soil organic carbon(SOC) storage, decreased in the following order: irrigated cropland(5,699 g/m^2) > sandy grassland(3,390 g/m^2) > rainfed cropland(2,411 g/m^2) > fixed dunes(821 g/m^2) > mobile dunes(463 g/m^2). SOC was significantly positively correlated with a large proportion of the other soil physico-chemical parameters. Our results suggest that the key issue in restoration of the degraded soils will be to increase SOC storage, which would also create a high potential for sequestering soil C in desertified areas of the Horqin Sandy Land. | YuQiang Li JianPeng Zhang XueYong Zhao TongHui Zhang YuLin Li XinPing Liu YinPing Chen | 2016 | Research in Cold and Arid Regions2016，8，6： | 4 |
| 12 | Effects of urban street trees on human thermal comfort and physiological indices: a case study in Changchun city, China显示文摘Planting trees along urban streets is one of the most important strategies to improve the urban thermal environment.However,the net impacts of urban street trees on human thermal comfort and physiological parameters are still less clear.On three similar east-west orientated streets with different degrees of tree cover-low(13%),medium(35%),and high(75%),urban microclimatic parameters and human physiological indices for six male students were simultaneously measured on three cloudless days in summer 2018.The results show that the differences in tree cover were predominant in influencing urban thermal environment and comfort.The street with the highest tree cover had significantly lower physiological equivalent temperature(PET) and more comfortable than the other two streets.The frequency of strong heat stress(PET> 35℃) was 64%,11 %,and 0%,respectively,for streets with low,medium,and high tree cover.For the six male university students,human physiological indices varied greatly across the three streets with different tree cover.Systolic blood pressure,diastolic blood pressure,and pulse rate increased with decreasing tree cover.The results also suggest that urban thermal environment and comfort had considerable impact on human physiological parameters.Our study provides reasons for urban planners to plant trees along streets to improve the thermal environment and promote urban sustainability. | Zhibin Ren Hongbo Zhao Yao Fu Lu Xiao Yulin Dong | 2022 | Journal of Forestry Research2022，33，3： | 4 |

| 14 | A vacuum ultraviolet laser with a submicrometer spot for spatially resolved photoemission spectroscopy显示文摘Vacuum ultraviolet(VUV)lasers have demonstrated great potential as the light source for various spectroscopies,which,if they can be focused into a small beam spot,will not only allow investigation of mesoscopic materials and structures but also find application in the manufacture of nano-objects with excellent precision.In this work,we report the construction of a 177 nm VUV laser that can achieve a record-small(〜0.76 μm)focal spot at a long focal length(~45 mm)by using a flat lens without spherical aberration.The size of the beam spot of this VUV laser was tested using a metal grating and exfoliated graphene flakes,and we demonstrated its application in a fluorescence spectroscopy study on pure and Tm3+-doped NaYF4 microcrystals,revealing a new emission band that cannot be observed in the traditional up-conversion process.In addition,this laser system would be an ideal light source for spatially and angleresolved photoemission spectroscopy. | Yuanhao Mao Dong Zhao Shen Yan Hongjia Zhang Juan Li Kai Han Xiaojun Xu Chuan Guo Lexian Yang Chaofan Zhang Kun Huang Yulin Chen | 2021 | Light(Science & Applications)2021，10，3： | 3 |
| 15 | Modes of genetic adaptations underlying functional innovations in the rumen显示文摘The rumen is the hallmark organ of ruminants and hosts a diverse ecosystem of microorganisms that facilitates efficient digestion of plant fibers.We analyzed 897 transcriptomes from three Cetartiodactyla lineages:ruminants,camels and cetaceans,as well as data from ruminant comparative genomics and functional assays to explore the genetic basis of rumen functional innovations.We identified genes with relatively high expression in the rumen,of which many appeared to be recruited from other tissues.These genes show functional enrichment in ketone body metabolism,regulation of microbial community,and epithelium absorption,which are the most prominent biological processes involved in rumen innovations.Several modes of genetic change underlying rumen functional innovations were uncovered,including coding mutations,genes newly evolved,and changes of regulatory elements.We validated that the key ketogenesis rate-limiting gene(HMGCS2)with five ruminant-specific mutations was under positive selection and exhibits higher synthesis activity than those of other mammals.Two newly evolved genes(LYZ1 and DEFB1)are resistant to Gram-positive bacteria and thereby may regulate microbial community equilibrium.Furthermore,we confirmed that the changes of regulatory elements accounted for the majority of rumen gene recruitment.These results greatly improve our understanding of rumen evolution and organ evo-devo in general. | Xiangyu Pan Yudong Cai Zongjun Li Xianqing Chen Rasmus Heller Nini Wang Yu Wang Chen Zhao Yong Wang Han Xu Songhai Li Ming Li Cunyuan Li Shengwei Hu Hui Li Kun Wang Lei Chen Bin Wei Zhuqing Zheng Weiwei Fu Yue Yang Tingting Zhang Zhuoting Hou Yueyang Yan Xiaoyang Lv Wei Sun Xinyu Li Shisheng Huang Lixiang Liu Shengyong Mao Wenqing Liu Jinlian Hua Zhipeng Li Guojie Zhang Yulin Chen Xihong Wang Qiang Qiu Brian PDalrymple Wen Wang Yu Jiang | 2021 | Science China(Life Sciences)2021，64，1： | 3 |

| 19 | The interaction between polyphyllin I and SQLE protein induces hepatotoxicity through SREBP-2/HMGCR/SQLE/LSS pathway显示文摘Polyphyllin I(PPI)and polyphyllin II(PII)are the main active substances in the Paris polyphylla.However,liver toxicity of these compounds has impeded their clinical application and the potential hepatotoxicity mechanisms remain to be elucidated.In this work,we found that PPI and PII exposure could induce significant hepatotoxicity in human liver cell line L-02 and zebrafish in a dose-dependent manner.The results of the proteomic analysis in L-02 cells and transcriptome in zebrafish indicated that the hepatotoxicity of PPI and PII was associated with the cholesterol biosynthetic pathway disorders,which were alleviated by the cholesterol biosynthesis inhibitor lovastatin.Additionally,3-hydroxy-3-methy-lglutaryl CoA reductase(HMGCR)and squalene epoxidase(SQLE),the two rate-limiting enzymes in the cholesterol synthesis,selected as the potential targets,were confirmed by the molecular docking,the overexpression,and knockdown of HMGCR or SQLE with siRNA.Finally,the pull-down and surface plasmon resonance technology revealed that PPI could directly bind with SQLE but not with HMGCR.Collectively,these data demonstrated that PPI-induced hepatotoxicity resulted from the direct binding with SQLE protein and impaired the sterol-regulatory element binding protein 2/HMGCR/SQLE/lanosterol synthase pathways,thus disturbing the cholesterol biosynthesis pathway.The findings of this research can contribute to a better understanding of the key role of SQLE as a potential target in drug-induced hepatotoxicity and provide a therapeutic strategy for the prevention of drug toxic effects with similar structures in the future. | Zhiqi Li Qiqi Fan Meilin Chen Ying Dong Farong Li Mingshuang Wang Yulin Gu Simin Guo Xianwen Ye Jiarui Wu Shengyun Dai Ruichao Lin Chongjun Zhao | 2023 | Journal of Pharmaceutical Analysis2023，13，1： | 2 |
| 20 | Carbon and nitrogen mineralization in soils along a desertification gradient in the semiarid Horqin Sandy Land, Northern China显示文摘This experiment was conducted in three sites along a desertification gradient in Horqin Sandy Land, Northern China. Soils una-mended and amended with five types of plant residue in a wide range of C:N ratios from 9.9 to 82.2 were incubated for 70 days, during which C and N mineralization were measured. Along the desertification gradient from fixed sand dune to semifixed, and mobile sand dune: cumulative CO2-C produced from the unamended soils was 231.6, 193.3 and 61.9 μg/g, respectively, while net inorganic N was 22.9, 17.6 and 0.9 mg/kg. Soils amended with residues produced more CO2-C than the unamended soils across all sites. During the first 10 days, C mineralization rate of residue-amended soils decreased with the increase of C:N ratio at each site. However, the mineralization rates were poorly correlated with the C:N ratio in subsequent stage of incubation. Soils of mobile sand dune amended with higher C:N ratio (more than 32) residues produced less CO2-C than that of fixed and semifixed sand dune. NO3--N was the predominant form of inorganic N during the mineralization process in sandy soils. Carbon-to-nitrogen ratio (C:N) can be regarded as a predictor of the speed of N mineralization in sandy soil. The more C. microphylla residue with the lowest C:N ratio (9.9) added in soils, the more net inorganic N released. Our results suggest that C. microphylla residue when added to soil would potentially provide short-term plant available N and improve the soil quality in sandy land. The desertification process postponed the release of inorganic N from plant residues. | YuQiang Li HaLin Zhao TongHui Zhang YuLin Li XiaoAn Zuo | 2010 | Research in Cold and Arid Regions2010，2，1： | 2 |
