| 1 | Mapping wetland changes in China between 1978 and 2008显示文摘Four wetland maps for all China have been produced,based on Landsat and CBERS-02B remote sensing data between 1978 and 2008 (1978,1990,2000 and 2008).These maps were mainly developed by manual interpretation and validated by substantial field investigation in 2009.Based on these maps,we analyzed the 2008 wetland distribution in China and discussed wetland changes and their drivers over the past 30 years.(i) There were about 324097 km 2 of wetlands in 2008,for which inland marshes or swamps were the most common wetland type (35%),with lakes (26%) second.Most of the wetlands were in Heilongjiang,Inner Mongolia,Qinghai and Tibet,occupying about 55% of the national wetland area.(ii) From 1978 to 2008,China's wetland area continually and significantly decreased,by about 33% based on changes in the wetland map.This was in sharp contrast to the increase in artificial wetlands,which increased by about 122%.Inland marshes accounted for the main loss of total wetlands from 1978 to 2000.From 2000 through 2008,riverine and lacustrine wetlands constituted the main wetland loss.Fortunately however,the rate of wetland loss decreased from 5523 to 831 km 2 /a.(iii) The change ratio of lost natural wetlands (including inland and coastal wetlands) to non-wetlands has decreased slightly over the past 30 years.From 1978 to 1990,nearly all natural wetlands (98%) lost were transformed into non-wetlands.However,the ratio declined to 86% from 1990 to 2000,and to 77% from 2000 to 2008.(iv) All Chinese provinces were divided into three groups according to patterns of wetland changes,which could relate to the driving forces of such changes.Tibet was completely different from other provinces,as it was one representative example in which there was a net wetland increase,because of global warming and decreased human activity since 1990.Increased economic development caused considerable wetland loss in most eastern provinces,and artificial wetlands increased. | NIU ZhenGuo ZHANG HaiYing WANG XianWei YAO WenBo ZHOU DeMin ZHAO KuiYi ZHAO Hui LI NaNa HUANG HuaBing LI CongCong YANG Jun LIU CaiXia LIU Shuang WANG Lin LI Zhan YANG ZhenZhong QIAO Fei ZHENG YaoMin CHEN YanLei SHENG YongWei GAO XiaoHong ZHU WeiHong WANG WenQing WANG Hong WENG YongLing ZHUANG DaFang LIU JiYuan LUO ZhiCai CHENG Xiao GUO ZiQi GONG Peng | 2012 | Chinese Science Bulletin2012，57，22： | 51 |

| 3 | Andrographolide sulfonate ameliorates lipopolysaccharide-induced acute lung injury in mice by down-regulating MAPK and NF-κB pathways显示文摘Acute lung injury(ALI) or acute respiratory distress syndrome(ARDS) is a severe, lifethreatening medical condition characterized by widespread inflammation in the lungs, and is a significant source of morbidity and mortality in the patient population. New therapies for the treatment of ALI are desperately needed. In the present study, we examined the effect of andrographolide sulfonate, a water-soluble form of andrographolide(trade name: Xi-Yan-Ping Injection), on lipopolysaccharide(LPS)-induced ALI and inflammation. Andrographolide sulfonate was administered by intraperitoneal injection to mice with LPS-induced ALI. LPS-induced airway inflammatory cell recruitment and lung histological alterations were significantly ameliorated by andrographolide sulfonate. Protein levels of pro-inflammatory cytokines in bronchoalveolar lavage fluid(BALF) and serum were reduced by andrographolide sulfonate administration. m RNA levels of pro-inflammatory cytokines in lung tissue were also suppressed. Moreover, andrographolide sulfonate markedly suppressed the activation of mitogen-activated protein kinase(MAPK) as well as p65 subunit of nuclear factor-κB(NF-κB). In summary, these results suggest that andrographolide sulfonate ameliorated LPS-induced ALI in mice by inhibiting NF-κB and MAPK-mediated inflammatory responses. Our study shows that water-soluble andrographolide sulfonate may represent a new therapeutic approach for treating inflammatory lung disorders. | Shuang Peng Nan Hang Wen Liu Wenjie Guo Chunhong Jiang Xiaoling Yang Qiang Xu Yang Sun | 2016 | Acta Pharmaceutica Sinica B2016，6，3： | 38 |
| 4 | The FTO/miR-181b-3p/ARL5B signaling pathway regulates cell migration and invasion in breast cancer显示文摘Background:N6-methyladenosine(m6A)RNA modification has been demonstrated to be a significant regulatory process in the progression of various tumors,including breast cancer.Fat mass and obesity-associated(FTO)enzyme,initially known as the obesity-related protein,is the first identified m6A demethylase.However,the relationship between FTO and breast cancer remains controversial.In this study,we aimed to elucidate the role and clinical significance of FTO in breast cancer and to explore the underlying mechanism.Methods:We first investigated the expression of FTO in breast cancer cell lines and tissues by quantitative reverse transcription-PCR(qRT-PCR),Western blotting,and immunohistochemistry.Wound healing assay and Transwell assay were performed to determine the migration and invasion abilities of SKBR3 and MDAMB453 cells with either knockdown or overexpression of FTO.RNA sequencing(RNA-seq)was conducted to decipher the downstream targets of FTO.qRT-PCR,luciferase reporter assay,and Western blotting were employed to confirm the existence of the FTO/miR-181b-3p/ARL5B axis.The biological function of ADP ribosylation factor like GTPase 5B(ARL5B)in breast cancer cells was evaluated by wound healing assay and Transwell invasion assay.Results:High FTO expression was observed in human epidermal growth factor receptor 2(HER2)-positive breast cancer,predicting advanced progression(tumor size[P<0.001],nuclear grade[P=0.001],peritumoral lymphovascular invasion[P<0.001),lymph node metastasis[P=0.002],and TNM stage[P=0.001])and poor prognosis.Moreover,FTO promoted cell invasion and migration in vitro.Mechanistically,RNA-seq and further confirmation studies suggested that FTO up-regulated ARL5B by inhibiting miR-181b-3p.We further verified that ARL5B also displayed carcinogenic activity in breast cancer cells.Conclusion:Our work demonstrated the carcinogenic activity of FTO in promoting the invasion and migration of breast cancer cells via the FTO/miR-181b-3p/ARL5B signaling pathway. | Yuanyuan Xu Shuang Ye Nan Zhang Shuhui Zheng Huatao Liu Kewen Zhou Ling Wang Yue Cao Peng Sun Tinghuai Wang | 2020 | Cancer Communications2020，40，10： | 24 |
| 5 | Characteristics of rare-earth elements (REE),strontium and neodymium isotopes in hydrothermal fluorites from the Bailashui tin deposit in the Furong ore field,southern Hunan Province,China显示文摘In this paper the authors present the REE concentrations and Sr and Nd isotopic compositions of fluorites from the Bailashui tin deposit of the Furong ore field,southern Hunan Province. The results showed that the total amount of REE in fluorites is usually low,ranging from 0.705 to 8.785 μg/g with the chondrite-normalized REE dis-tribution patterns similar to those of the Qitianling granites in the study area,characterized by LREE-enrichment patterns with pronounced negative Eu anomalies. The fluorites vary in Sr isotopic composition within the range of 0.7083-0.7091,the values are lower than those of the granites and higher than those of the host carbonate rocks in this area. The εNd(t) values of fluorites vary between -9.4 and +10.3,revealing that both the crust-and mantle-source materials were involved in the ore-forming hydrothermal fluids. Combined with previous studies on this ore deposit,the Bailashui tin deposit is temporally and spatially closely related with granitic magmatism in this area. The hydro-thermal fluorites are the product of fluid/rock interactions between granitic magmatic hydrothermal fluid and marine carbonate rocks. The REE and F in the ore-forming fluid were derived from the granites,whereas Sr in the ore-forming fluid came mainly from the granitic magmatic hydrothermal fluid and marine carbonate rocks,although variations in Sr isotopic composition cannot be explained by a simple mixture of these two end-members. Evidence demonstrated that the ore-forming fluids are of crustal-mantle mixing origin,but that the fluids were probably in-completely homogenized and this may be caused by inhomogeneous mixing of the fluids of different sources. | YUAN Shunda PENG Jiantang HU Ruizhong BI Xianwu QI Liang LI Zhaoli LI Xiaomin SHUANG Yan | 2008 | Chinese Journal Of Geochemistry2008，27，4： | 16 |
| 6 | Decrease of GSK3βSer-9 Phosphorylation Induced Osteoblast Apoptosis in Rat Osteoarthritis Model显示文摘Nowadays,the cumulative intake of glucocorticoids has become the most common pathogenic factor for non-traumatic osteonecrosis of the femoral head(ONFH).Apoptosis of osteoblasts is considered as the main reason of ONFH at the molecular level.Glycogen synthase kinase 3β(GSK3β)is an important regulator of cellular differentiation and apoptosis pathway,which can modulate the balance between osteoblasts and osteoclasts.Several studies have reported about its function in osteoporosis,but little is known about it in osteonecrosis.In our study,lipopolysaccharide and methylprednisolone were utilized to establish a rat ONFH model.The phosphorylation of GSK3βSer-9 was decreased in the model.Western blotting examination ofβ-catenin,Bcl-2,Bax and caspase-3 revealed that the osteoblasts were apoptotic.In dexamethasone(Dex)-incubated primary osteoblasts,the expression profile of GSK3βphosphorylation and apoptotic factors were consistent with those in the rat ONFH model.To further investigate the regulation of osteonecrosis caused by GSK3β,the expression and function of GSK3βwere inhibited in Dex-incubated primary osteoblasts.The knockdown of GSK3βby siRNA decreased the expression of Bax and cleaved caspase-3,but increased Bcl-2 andβ-catenin.On the other hand,selective inhibition of GSK3βfunction by LiCl counteracted the activation of caspase-3 induced by Dex.Our work is the first study about the GSK3P phosphorylation in ONFH,and provides evidence for further therapeutic methods. | Shuang DENG Zhi-gang NIE Pu-ji PENG Yang LIU Sai XING Lin-sheng LONG Hao PENG | 2019 | Current Medical Science2019，39，1： | 10 |

| 9 | Subchronic Oral Toxicity Evaluation of Lanthanum: A 90-day, Repeated Dose Study in Rats显示文摘Objective The present study was undertaken to evaluate the subchronic toxicity of lanthanum and to determine the no observed adverse effect level(NOAEL),which is a critical factor in the establishment of an acceptable dietary intake(ADI).Methods In accordance with the Organization for Economic Co-operation and Development(OECD) testing guidelines,lanthanum nitrate was administered once daily by gavage to Sprague-Dawley(SD) rats at dose levels of 0,1.5,6.0,24.0,and 144.0 mg/kg body weight(BW) per day for 90 days,followed by a recovery period of 4 weeks in the 144.0 mg/kg BW per day and normal control groups.Outcome parameters were mortality,clinical symptoms,body and organ weights,serum chemistry,and food consumption,as well as ophthalmic,urinary,hematologic,and histopathologic indicators.The benchmark dose(BMD) approach was applied to estimate a point of departure for the hazard risk assessment of lanthanum.Results Significant decreases were found in the 144.0 mg/kg BW group in the growth index,including body weight,organ weights,and food consumption.This study suggests that the NOAEL of lanthanum nitrate is 24.0 mg/kg BW per day.Importantly,the 95% lower confidence value of the benchmark dose(BMDL) was estimated as 9.4 mg/kg BW per day in females and 19.3 mg/kg BW per day in males.Conclusion The present subchronic oral exposure toxicity study may provide scientific data for the risk assessment of lanthanum and other rare earth elements(REEs). | FANG Hai Qin YU Zhou ZHI Yuan FANG Jin LI Chen Xi WANG Yi Mei PENG Shuang Qing JIA Xu Dong | 2018 | Biomedical and Environmental Sciences2018，31，5： | 7 |
| 10 | Association of genotypes of rs671 within ALDH2 with risk for gastric cardia adenocarcinoma in the Chinese Han population in high-and low-incidence areas显示文摘Objective: This study aimed to determine if gastric cardia adenocarcinoma(GCA) risk was associated with the lys(A or *2) allele at the rs671(glu504lys) polymorphism within the aldehyde dehydrogenase 2(ALDH2) gene in a Chinese Han population. We also aimed to investigate ALDH2 genotypic distributions between subjects from high- and low-incidence areas for both GCA and esophageal squamous cell carcinoma(ESCC).Methods: We designed a case-control study including 2,686 patients with GCA and 3,675 control subjects from high- and lowincidence areas for both GCA and ESCC in China. Taq Man allele discrimination assay was used to genotype the rs671 polymorphism. χ~2 test and binary logistic regression analysis were used to estimate the odds ratios for the development of GCA,and multivariate ordinal logistic regression was used to analyze ALDH2 genotypic distributions among different groups.Results: Compared with ALDH2*1/*1 homozygotes, ALDH2*1/*2 and ALDH2*2/*2 carriers did not increase the risk for GCA in the Chinese Han population(P>0.05). Interestingly, the ratio of homozygous or heterozygous ALDH2 *2 carriers in highincidence areas for both GCA and ESCC was lower than that in low-incidence areas(P<0.001).Conclusions: Genotypes of rs671 at ALDH2 may not increase GCA susceptibility in Chinese Han populations. In addition, the ALDH2 genotypic distribution differs between Chinese Han populations from high- and low-incidence areas for both GCA and ESCC. Our findings may shed light on the possible genetic mechanism for the dramatic geographic differences of GCA occurrence in China. | Lian-Qun Zhang Xin Song Xue-Ke Zhao Jia Huang Peng Zhang Lu-Wen Wang Hui Meng Jian-Wei Ku Guo-Qiang Kong Tao Jiang Xin-Min Li Xiao-Long Lv Teng Ma Guo Yuan Min-Jie Wu Shou-Jia Hu Shuang Lv Tang-Juan Zhang Ling-Fen Ji Zong-Min Fan Neng-Chao Wang Yao-Wen Zhang Fu-You Zhou Li-Dong Wang | 2017 | Cancer Biology & Medicine2017，14，1： | 7 |

| 12 | Pregnane receptor gene polymorphisms,pathogenic bacteria distribution and drug sensitivity,and TCM dyndrome differentiation in patients with cholelithiasis显示文摘Objective:To investigate the distribution of pathogens and drug resistance in bile and the association between the pregane X receptor(PXR) gene polymorphisms,traditional Chinese medicine(TCM) syndromes and the risk of cholesterol gallstone disease(CGD).Methods:A total of 392 samples were enrolled in this study from January 2014 to February 2015.among which 192 patients were with CGD.and 200 samples were healthy.Strains were isolated and susceptibility testing was the disk diffusion method susceptibility testing.The patients were divided into hepatochlic hygropyrexia.stagnation of liver-qi.and the accumulation of damp.The PXR gene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism.The association between the PXR gene polymorphisms and the risk of CGD was examined by logistic regression analysis.Results:A total of 192 cases were detected in 230 of bile culture pathogens,including Grain-negative bacteria 133(57.83%),Gram-positive bacteria76(33.04%),and fungi 21(9.13%).The top five pathogens were Escherichia coli,Klebsiella pneumoniae.Enterococcus faecalis,Candida albicans,and Enterococcus feces,ot which 110 cases was of single infection.48 cases of mixed infection of two strains,eight cases of mixed infection of three bacteria.Among 59 Escherichia coli,the yield extended-spectrum beta-laetamases had 40(67.80%).The hepatochlic hygropyrexia was the most TCM syndrome,followed by stagnation of liver-qi.and the accumulation of damp was least.Different pathogens and the rs6785049 genotypes distributed differently in cholelithiasis patients with different TCM syndromes(P<0.05).In hepatochlic hygropyrexia patients the Gram-negative bacteria was most.There was significant differences between CGD group and control group in rs6785049(P<0.001).Comparison with wild-type portable GG.GA genotype increased the risk of the occurrence of gallstones(OR=0.40.95%CI:0.16-0.79);likewise,carrying the GA + AA genotype also increased the risk(OR=0.38,95%CI:0.19-0.81).There was no significant differences in rs2276707,rs3814055 site polymorphic loci alleles in CGD group and control group.Conclusions:In the treatment of cholelithiasis,bile samples should be collected for bacterial culture and sensitivity test,and drugs should be strictly chosen based on the results.The rs6785049 polymorphisms in PXR gene may increase the risk of gallstones ontogeny,and gallstones can he early detected and prevented by detecting genotypes.rs6785049 polymorphisms in PXR gene may has relationship with TCM syndromes. | Yi-Qiang Xie Jing-Zhe Zhang Hua Zhang Lei Peng Shuang Zhou Li-Zhuo Li Bang-Jiang Fang Chuan-Zhu Lyu | 2016 | Asian Pacific Journal of Tropical Medicine2016，9，4： | 7 |
| 13 | The Lyman-alpha Solar Telescope(LST) for the ASO-S mission——Ⅱ. design of LST显示文摘As one of the three payloads for the Advanced Space-based Solar Observatory(ASO-S)mission,the Lyman-alpha(Lyα)Solar Telescope(LST)is composed of three instruments:a Solar Corona Imager(SCI),a LyαSolar Disk Imager(SDI)and a full-disk White-light Solar Telescope(WST).When working in-orbit,LST will simultaneously perform high-resolution imaging observations of all regions from the solar disk to the inner corona up to 2.5 R⊙(R⊙stands for the mean solar radius)with a spatial resolution of 4.8′′and 1.2′′for coronal and disk observations,respectively,and a temporal resolution of 30–120 s and 1–120 s for coronal and disk observations,respectively.The maximum exposure time can be up to20 s due to precise pointing and image stabilization function.Among the three telescopes of LST,SCI is a dual-waveband coronagraph simultaneously and independently observing the inner corona in the HI Lyα(121.6±10 nm)line and white light(WL)(700±40 nm)wavebands by using a narrowband Lyαbeam splitter and has a field of view(FOV)from 1.1 to 2.5 R⊙.The stray-light suppression level can attain<10^-6 B⊙(B⊙is the mean brightness of the solar disk)at 1.1 R⊙and≤5×10^-8 B⊙at 2.5 R⊙.SDI and WST are solar disk imagers working in the Lyαline and 360.0 nm wavebands,respectively,which adopt an off-axis two-mirror reflective structure with an FOV up to 1.2 R⊙,covering the inner coronal edge area and relating to coronal imaging.We present the up-to-date design for the LST payload. | Bo Chen Hui Li Ke-Fei Song Quan-Feng Guo Pei-Jie Zhang Ling-Ping He Shuang Dai Xiao-Dong Wang Hai-Feng Wang Chun-Long Liu Hong-Ji Zhang Guang Zhang Yunqi Wang Shi-Jie Liu Hong-Xin Zhang Lei Liu Shi-Lei Mao Yang Liu Jia-Hao Peng Peng Wang Liang Sun Yang Liu Zhen-Wei Han Yan-Long Wang Kun Wu Guang-Xing Ding Peng Zhou Xin Zheng Ming-Yi Xia Qing-Wen Wu Jin-Jiang Xie Ya Chen Shu-Mei Song Hong Wang Bo Zhu Chang-Bo Chu Wen-Gang Yang Li Feng Yu Huang Wei-Qun Gan Ying Li Jing-Wei Li Lei Lu Jian-Chao Xue Bei-Li Ying Ming-Zhe Sun Cheng Zhu Wei-Min Bao Lei Deng Zeng-Shan Yin | 2019 | Research in Astronomy and Astrophysics2019，19，11： | 6 |
| 14 | Phytochrome B interacts with SWC6 and ARP6 to regulate H2A.Z deposition and photomorphogensis in Arabidopsis显示文摘Light serves as a crucial environmental cue which modulates plant growth and development, and which is controlled by multiple photoreceptors including the primary red light photoreceptor,phytochrome B(phyB). The signaling mechanism of phyB involves direct interactions with a group of basic helix-loop-helix(bHLH) transcription factors, PHYTOCHROME-INTERACTING FACTORS(PIFs), and the negative regulators of photomorphogenesis, COP1 and SPAs. H2 A.Z is an evolutionarily conserved H2 A variant which plays essential roles in transcriptional regulation. The replacement of H2 A with H2 A.Z is catalyzed by the SWR1 complex. Here, we show that the Pfr form of phyB physically interacts with the SWR1 complex subunits SWC6 and ARP6. phyB and ARP6 coregulate numerous genes in the same direction,some of which are associated with auxin biosynthesis and response including YUC9, which encodes a rate-limiting enzyme in the tryptophandependent auxin biosynthesis pathway. Moreover,phyB and HY5/HYH act to inhibit hypocotyl elongation partially through repression of auxin biosynthesis. Based on our findings and previous studies, we propose that phyB promotes H2 A.Z deposition at YUC9 to inhibit its expression through direct phyB-SWC6/ARP6 interactions,leading to repression of auxin biosynthesis, and thus inhibition of hypocotyl elongation in red light. | Xuxu Wei Wanting Wang Peng Xu Wenxiu Wang Tongtong Guo Shuang Kou Minqing Liu Yake Niu Hong-Quan Yang Zhilei Mao | 2021 | Journal of Integrative Plant Biology2021，63，6： | 6 |
| 15 | Tectonic and Environmental Evolutions of the Northern Tibetan Plateau Prior to the Collision of India with Asia显示文摘Tectonic and environmental patterns and evolution of the present North Tibetan Plateau(NTP) prior to the India collision with Asia is significant to understand the formation of the Tibetan Plateau and its influence on the environment. In this study, we integrated and analyzed the tectonostratigraphy and the special sedimentary layers whose climatic implications are clear in the NTP. Additionally, we stressed the tectonic and environmental events and their evolutions from the Mesozoic to the Early Cenozoic. Our results show that four tectonic phases, which sequentially took place during the Triassic, Jurassic, Cretaceous and Paleogene, played an important role on the formation of the North Tibet. The climate was basically dry and hot from the Triassic to the Eocene and became dry and cool since the Oligocene in this region. The climatic evolution was characterized by a transition from a wet and hot phase during the Triassic- Middle Jurassic, to a dry and hot phase during the Late Jurassic- Eocene. Both phases encompassed 5 wet and hot periods followed by 5 dry and hot climate events, respectively. In addition, we found that the tectonic deformation and the climatic conditions were spatially and temporally different. In detail, in the regions north of the PaleoTian Shan and Paleo-Qilian Mts. the tectonic deformation and climatic condition were stronger and wetter than in regions south of the Paleo-Tian Shan and Paleo-Qilian Mts. during the Late Triassic – Jurassic. Whereas in the Cretaceous, the tectonic movement was intensive in the west but steady in the east, and climate was dry in the south but wet in the north of NTP. The formation of the tectonic and climatic patterns in NTP were the consequence of either global climate change or regional tectonics, including the Paleo-Asian Ocean closure and the Qiangtang block, Lhasa block and India plate collision subsequently to Asia. Furthermore, the regional tectonic events occurred before any global climate change and drove the climatic change in the NTP. | DAI Shuang ZHANG Mingzhen PENG Dongxiang WANG Huawei WU Maoxian CHEN Ruiling ZHANG Xiang | 2014 | Acta Geologica Sinica(English Edition)2014，88，2： | 6 |
| 16 | Microstructural and textural evolutions in multilayered Ti/Cu composites processed by accumulative roll bonding显示文摘Ti/Cu multilayered composites were fabricated via accumulative roll bonding(ARB). During codeformation of the constituent metals, the hard Ti layers necked preferentially and then fragmented with the development of shear bands. Transmission electron microscopy showed that with increasing ARB cycles, grains in Ti were significantly refined even though dynamic recrystallization has occurred. For Cu the significant grain refinement was only found within the shear banded region when the composite was processed after five ARB cycles. Due to the diffusion of Cu atoms into Ti at the heterophase interfaces, amorphization with a width less than 10 nm was identified even in the composite processed by one cycle. At higher ARB cycles, the width of amorphous region increased and intermetallic compounds CuTi appeared from the region. The lattice defects introduced at the heterophase interfaces under roll bonding was responsible for the formation of the nano-scaled compounds. X-ray diffraction showed that an abnormal {1120} fiber texture was developed in Ti layers, while significant brass-type textures were developed in Cu layers. Some orientations along the {1120} fiber favored the prismatic < a> slip for Ti.Tensile tests revealed the elevated strength without a substantial sacrifice of ductility in the composites during ARB. The unique mechanical properties were attributed to the significantly refined grains in individual metals, the good bonding between the constituent metals, as well as the development of an abnormal {1120} fiber texture in Ti layers. | Shuang Jiang Ru Lin Peng Nan Jia Xiang Zhao Liang Zuo | 2019 | Journal of Materials Science & Technology2019，35，6： | 6 |
| 17 | Mesenchymal stem cell treatment improves outcome of COVID-19 patients via multiple immunomodulatory mechanisms显示文摘The infusion of coronavirus disease 2019(COVID-19)patients with mesenchymal stem cells(MSCs)potentially improves clinical symptoms,but the underlying mechanism remains unclear.We conducted a randomized,single-blind,placebo-controlled(29 patients/group)phase II clinical trial to validate previous findings and explore the potential mechanisms.Patients treated with umbilical cord-derived MSCs exhibited a shorter hospital stay(P=0.0198)and less time required for symptoms remission(P=0.0194)than those who received placebo.Based on chest images,both severe and critical patients treated with MSCs showed improvement by day 7(P=0.0099)and day 21(P=0.0084).MSC-treated patients had fewer adverse events.MSC infusion reduced the levels of C-reactive protein,proinflammatory cytokines,and neutrophil extracellular traps(NETs)and promoted the maintenance of SARS-CoV-2-specific antibodies.To explore how MSCs modulate the immune system,we employed single-cell RNA sequencing analysis on peripheral blood.Our analysis identified a novel subpopulation of VNN2+hematopoietic stem/progenitorlike(HSPC-like)cells expressing CSF3R and PTPRE that were mobilized following MSC infusion.Genes encoding chemotaxis factors—CX3CR1 and L-selectin—were upregulated in various immune cells.MSC treatment also regulated B cell subsets and increased the expression of costimulatory CD28 in T cells in vivo and in vitro.In addition,an in vivo mouse study confirmed that MSCs suppressed NET release and reduced venous thrombosis by upregulating kindlin-3 signaling.Together,our results underscore the role of MSCs in improving COVID-19 patient outcomes via maintenance of immune homeostasis. | Rongjia Zhu Tingdong Yan Yingmei Feng Yan Liu Hongcui Cao Gongxin Peng Yanlei Yang Zhen Xu Jingqi Liu Wei Hou Xiaoyue Wang Zhe Li Luchan Deng Shihua Wang Jing Li Qin Han Hongling Li Guangliang Shan Yinghao Cao Xingyan An Jianshe Yan Zhonghui Zhang Huafei Li Xuebin Qu Jiaqi Zhu Shumin Zhou Jiao Wang Fengchun Zhang Jinming Gao Ronghua Jin Dayong Xu Yan-Qing Ma Tao Huang Shuang Peng Zhi Zheng Ilia Stambler Eric Gilson Lee Wei Lim Alexey Moskalev Antonio Cano Sasanka Chakrabarti Brun Ulfhake Huanxing Su Haoying Xu Sihuan Xu Feng Wei Holly MBrown-Borg Kyung-Jin Min Georgina Ellison-Hughes Calogero Caruso Kunlin Jin Robert Chunhua Zhao | 2021 | Cell Research2021，31，12： | 5 |
| 18 | The effects of vegetation restoration strategies and seasons on soil enzyme activities in the Karst landscapes of Yunnan, southwest China显示文摘Soil enzymes play a vital role in biogeochemical cycling and ecosystem functions.In this study,we examined the response of six soil enzymes to changes in physicochemical properties resulting from changes in season and vegetation and geological conditions.Catalase,urease,acid phosphatase,invertase,amylase,and cellulase not only promote carbon,nitrogen,and phosphorus cycling,but also participate in the decomposition of harmful substances.Thirty-six soil samples were collected from karst and non-karst areas in two different seasons and from three different types of vegetation in Yunnan province,southwest China.Both vegetation types and season had significant effects on soil physicochemical properties and enzyme activities.In the same plot,soil water content,electrical conductivity,organic carbon,total nitrogen,and total phosphorus increased in the rainy season,indicating enhanced microbial metabolic activity.With the exception of urease activity,the remaining five enzymes showed higher activity in the rainy season.Changes in activities between the two seasons were significant in all samples.In the same season,activity levels of soil enzymes were higher in karst areas than in non-karst areas,and higher in natural forest than in artificial forests.The transformative abilities of soil elements are higher in karst areas than in non-karst areas,and higher in natural forests than in artificial forests.Correlation analysis showed that the activities of the six enzymes correlated significantly;however,soil physical and chemical indices,such as organic matter,pH,and moisture,which are essential for enzyme activity,differed by season.Redundancy analysis also revealed that the main factors influencing enzyme activity differed between the two seasons.The results from this study provide a theoretical basis for further research on the restoration of natural ecological systems in karst landscapes. | Zhouzhou Fan Shuyu Lu Shuang Liu Zhaorong Li Jiaxin Hong Jinxing Zhou Xiawei Peng | 2020 | Journal of Forestry Research2020，31，5： | 5 |
| 19 | Protective Effect of Human Umbilical Cord Mesenchymal Stem Cells in Glucocorticoid-induced Osteonecrosis of Femoral Head显示文摘Objective:To evaluate the effect of human umbilical cord mesenchymal stem cells(hUC-MSCs)on preventing rats from glucocorticoid-induced osteonecrosis of femoral head(GC-ONFH)in the early stage in vivo and to investigate the possible mechanism of hUC-MSCs in regulating the balance of osteogenesis and adipogenesis.Methods:All rats were randomly divided into 3 groups:control group(C group),model group(M group),and intervention group(Ⅰ group).The model of GC-ONFH was developed by a sequential administration of lipopolysaccharide and methylprednisolone.The rats in the Ⅰ group were treated with caudal vein injection of hUC-MSCs.Six weeks later,the blood samples were obtained to measure the activity of alkaline phosphatase(ALP)and the content of triglyceride(TG)in serum,and the femoral heads were harvested and observed by hematoxylin-eosin staining,Micro-CT,Western blot and real-time quantitative polymerase chain reaction.Results:After intervention of hUC-MSCs,the necrosis rate of femoral head decreased from 83%(10/12)to 33%(4/12),the rate of empty bone lacuna was significantly decreased,the activity of ALP increased significantly,the content of TG decreased significantly,the bone density increased obviously,the expression of RUNX2 and Col Ⅰ increased significantly and the expression of PPARγ decreased significantly.Conclusion:These results revealed that caudal vein injection of hUC-MSCs can effectively reduce the incidence of GC-ONFH in rats by increasing ALP activity and reducing TG content in serum,increasing bone mineral density,promoting the expression of RUNX2 and Col I,and inhibiting the expression of PPARγ. | Chen QIU Jian-lin ZHOU Shuang DENG Lin-sheng LONG Hao PENG | 2021 | Current Medical Science2021，41，5： | 4 |
| 20 | The adsorption properties of NaY zeolite for separation of ethylene glycol and 1,2-butanediol: Experiment and molecular modelling显示文摘The separation of ethylene glycol(EG)and 1,2-butanediol(1,2-BDO)azeotrope in the synthesis process of EG via coal and biomass is becoming of increasing commercial and environmental importance.Selective adsorption is deemed as the most promising methods because of energy saving and environment favorable.In this paper,NaY zeolite was used to separate 1,2-BDO from EG,and its adsorption properties was then investigated.The isotherms of EG and 1,2-BDO in vapor and liquid phases from 298 to 328 K indicated that they fitted Langmuir model quite well,and the NaY zeolite absorbent favored EG more than 1,2-BDO.The Grand Canonical Monte Carlo(GCMC)and molecular dynamics(MD)simulation techniques were conducted to investigate the competition adsorption and diffusion characteristics in different adsorption regions.It was observed that EG and 1,2-BDO molecules all have the most probable locations of the center of the 12-membered ring near the Na cations.The diffusivities of EG are lower than those of 1,2-BDO at the same adsorption concentration.At last,the breakthrough curves of the binary mixture regressed from the empirical Dose–Response model in fixed-bed column showed that the adsorption selectivity of EG could reach to as high as 2.43,verified that the NaY zeolite could effectively separate EG from 1,2-BDO.This work is also helpful for further separation of other dihydric alcohol mixtures from coal and biomass fermentation. | Pei Xiong Peng He Yixin Qu Liguo Wang Yan Cao Shuang Xu Jiaqiang Chen Muhammad Ammar Huiquan Li | 2021 | Green Energy & Environment2021，6，1： | 3 |
