| 1 | Transplantation of UC-MSCs on collagen scaffold activates follicles in dormant ovaries of POF patients with long history of infertility显示文摘Premature ovarian failure(POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study,umbilical cord mesenchymal stem cells on a collagen scaffold(collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3 a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF. | Lijun Ding Guijun Yan Bin Wang Lu Xu Yan Gu Tong Ru Xiaoying Cui Lei Lei Jingyu Liu Xiaoqiang Sheng Bin Wang Chunxue Zhang Yanjun Yang Ruiwei Jiang Jianjun Zhou Na Kong Feifei Lu Huaijun Zhou Yannan Zhao Bing Chen Yali Hu Jianwu Dai Haixiang Sun | 2018 | Science China(Life Sciences)2018，61，12： | 43 |

| 4 | Developing the Science Product Algorithm Testbed for Chinese Next-Generation Geostationary Meteorological Satellites:Fengyun-4 Series显示文摘Fengyun-4A(FY-4A), the first of the Chinese next-generation geostationary meteorological satellites, launched in2016, offers several advances over the FY-2: more spectral bands, faster imaging, and infrared hyperspectral measurements. To support the major objective of developing the prototypes of FY-4 science algorithms, two science product algorithm testbeds for imagers and sounders have been developed by the scientists in the FY-4 Algorithm Working Group(AWG). Both testbeds, written in FORTRAN and C programming languages for Linux or UNIX systems, have been tested successfully by using Intel/g compilers. Some important FY-4 science products, including cloud mask, cloud properties, and temperature profiles, have been retrieved successfully through using a proxy imager, Himawari-8/Advanced Himawari Imager(AHI), and sounder data, obtained from the Atmospheric Infra Red Sounder, thus demonstrating their robustness. In addition, in early 2016, the FY-4 AWG was developed based on the imager testbed—a near real-time processing system for Himawari-8/AHI data for use by Chinese weather forecasters.Consequently, robust and flexible science product algorithm testbeds have provided essential and productive tools for popularizing FY-4 data and developing substantial improvements in FY-4 products. | Min MIN Chunqiang WU Chuan LI Hui LIU Na XU Xiao WU Lin CHEN Fu WANG Fenglin SUN Danyu QIN Xi WANG Bo LI Zhaojun ZHENG Guangzhen CAO Lixin DONG | 2017 | Journal of Meteorological Research2017，31，4： | 35 |

| 9 | Root microbiota shift in rice correlates with resident time in the field and developmental stage显示文摘Land plants in natural soil form intimate relationships with the diverse root bacterial microbiota. A growing body of evidence shows that these microbes are important for plant growth and health. Root microbiota composition has been widely studied in several model plants and crops; however, little is known about how root microbiota vary throughout the plant's life cycle under field conditions. We performed longitudinal dense sampling in field trials to track the time-series shift of the root microbiota from two representative rice cultivars in two separate locations in China. We found that the rice root microbiota varied dramatically during the vegetative stages and stabilized from the beginning of the reproductive stage, after which the root microbiota underwent relatively minor changes until rice ripening. Notably, both rice genotype and geographical location influenced the patterns of root microbiota shift that occurred during plant growth. The relative abundance of Deltaproteobacteria in roots significantly increased overtime throughout the entire life cycle of rice, while that of Betaproteobacteria, Firmicutes, and Gammaproteobacteria decreased. By a machine learning approach, we identified biomarker taxa and established a model to correlate root microbiota with rice resident time in the field(e.g., Nitrospira accumulated from 5 weeks/tillering in field-grown rice). Our work provides insights into the process of rice root microbiota establishment. | Jingying Zhang Na Zhang Yong-Xin Liu Xiaoning Zhang Bin Hu Yuan Qin Haoran Xu Hui Wang Xiaoxuan Guo Jingmei Qian Wei Wang Pengfan Zhang Tao Jin Chengcai Chu Yang Bai | 2018 | Science China(Life Sciences)2018，61，6： | 24 |
| 10 | Baicalin induces ferroptosis in bladder cancer cells by downregulating FTH1显示文摘Ferroptosis is a non-apoptotic regulated cell death caused by iron accumulation and subsequent lipid peroxidation.Currently,the therapeutic role of ferroptosis on cancer is gaining increasing interest.Baicalin an active component in Scutellaria baicalensis Georgi with anticancer potential various cancer types;however,the effects of baicalein on bladder cancer and the underlying molecular mechanisms remain largely unknown.In the study,we investigated the effect of baicalin on bladder cancer cells5637 and KU-19-19.As a result,we show baicalin exerted its anticancer activity by inducing apoptosis and cell death in bladder cancer cells.Subsequently,we for the first time demonstrate baicalin-induced ferroptotic cell death in vitro and in vivo,accompanied by reactive oxygen species(ROS) accumulation and intracellular chelate iron enrichment.The ferroptosis inhibitor deferoxamine but not necrostatin-1,chloroquine(CQ),N-acetyl-L-cysteine,L-glutathione reduced,or carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]-fluoromethylketone(Z-VAD-FMK) rescued baicalin-induced cell death,indicating ferroptosis contributed to baicalin-induced cell death.Mechanistically,we show that ferritin heavy chain1(FTH1) was a key determinant for baicalin-induced ferroptosis.Overexpression of FTH1 abrogated the anticancer effects of baicalin in both 5637 and KU19-19 cells.Taken together,our data for the first time suggest that the natural product baicalin exerts its anticancer activity by inducing FTH1-dependent ferroptosis,which will hopefully provide a prospective compound for bladder cancer treatment. | Na Kong Xiaying Chen Jiao Feng Ting Duan Shuiping Liu Xueni Sun Peng Chen Ting Pan Lili Yan Ting Jin Yu Xiang Quan Gao Chengyong Wen Weirui Ma Wencheng Liu Mingming Zhang Zuyi Yang Wengang Wang Ruonan Zhang Bi Chen Tian Xie Xinbing Sui Wei Tao | 2021 | Acta Pharmaceutica Sinica B2021，11，12： | 23 |

| 14 | Recovery of scandium from bauxite residue——red mud:a review显示文摘Red mud is a slimy caustic residue generated from alumina production. Taking into account the relatively considerable content and availability of scandium,red mud can be viewed as an important and promising scandium resource rather than a solid waste. This paper is primarily to review the investigations of scandium recovery from red mud based on the most widely used hydrometallurgical processes including acid leaching, solvent extraction and ion exchange adsorption. It is thought that recovery of scandium from red mud should be considered as a direct objective rather than a by-product in the development of overall flowsheet. In order to achieve environmentally-friendly processes with high scandium recovery and low cost, more attention is required to be paid to optimizing the selective leaching of scandium to decrease mineral acid consumption and alleviate pollution,and developing new solvent extraction systems and novel ion exchange adsorption materials with high selectivity and recognition for scandium. | Na Zhang Hong-Xu Li Xiao-Ming Liu | 2016 | Rare Metals2016，35，12： | 19 |
| 15 | Prognostic value of risk scoring systems for cirrhotic patients with variceal bleeding显示文摘BACKGROUND Acute variceal bleeding is one of the deadliest complications of cirrhosis,with a high risk of in-hospital rebleeding and mortality.Some risk scoring systems to predict clinical outcomes in patients with upper gastrointestinal bleeding have been developed.However,for cirrhotic patients with variceal bleeding,data regarding the predictive value of these prognostic scores in predicting in-hospital outcomes are limited and controversial.AIM To validate and compare the overall performance of selected prognostic scoring systems for predicting in-hospital outcomes in cirrhotic patients with variceal bleeding.METHODS From March 2017 to June 2019,cirrhotic patients with acute variceal bleeding were retrospectively enrolled at the Second Affiliated Hospital of Xi’an Jiaotong University.The clinical Rockall score(CRS),AIMS65 score(AIMS65),Glasgow-Blatchford score(GBS),modified GBS(mGBS),Canada-United Kingdom-Australia score(CANUKA),Child-Turcotte-Pugh score(CTP),model for endstage liver disease(MELD)and MELD-Na were calculated.The overall performance of these prognostic scoring systems was evaluated.RESULTS A total of 330 cirrhotic patients with variceal bleeding were enrolled;the rates of in-hospital rebleeding and mortality were 20.3%and 10.6%,respectively.For inhospital rebleeding,the discriminative ability of the CTP and CRS were clinically acceptable,with area under the receiver operating characteristic curves(AUROCs)of 0.717(0.648-0.787)and 0.716(0.638-0.793),respectively.The other tested scoring systems had poor discriminative ability(AUROCs<0.7).For inhospital mortality,the CRS,CTP,AIMS65,MELD-Na and MELD showed excellent discriminative ability(AUROCs>0.8).The AUROCs of the mGBS,CANUKA and GBS were relatively small,but clinically acceptable(AUROCs>0.7).Furthermore,the calibration of all scoring systems was good for either inhospital rebleeding or death.CONCLUSION For cirrhotic patients with variceal bleeding,in-hospital rebleeding and mortality rates remain high.The CTP and CRS can be used clinically to predict in-hospital rebleeding.The performances of the CRS,CTP,AIMS65,MELD-Na and MELD are excellent at predicting in-hospital mortality. | Xin-Xing Tantai Na Liu Long-Bao Yang Zhong-Cao Wei Cai-Lan Xiao Ya-Hua Song Jin-Hai Wang | 2019 | World Journal of Gastroenterology2019，25，45： | 19 |
| 16 | Single-cell transcriptomics reveals regulators underlying immune cell diversity and immune subtypes associated with prognosis in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is an aggressive malignancy with extremely skewed ethnic and geographic distributions.Increasing evidence indicates that targeting the tumor microenvironment(TME)represents a promising therapeutic approach in NPC,highlighting an urgent need to deepen the understanding of the complex NPC TME.Here,we generated single-cell transcriptome profiles for 7581 malignant cells and 40,285 immune cells from fifteen primary NPC tumors and one normal sample.We revealed malignant signatures capturing intratumoral transcriptional heterogeneity and predicting aggressiveness of malignant cells.Diverse immune cell subtypes were identified,including novel subtypes such as CLEC9A^+dendritic cells(DCs).We further revealed transcriptional regulators underlying immune cell diversity,and cell–cell interaction analyses highlighted promising immunotherapeutic targets in NPC.Moreover,we established the immune subtype-specific signatures,and demonstrated that the signatures of macrophages,plasmacytoid dendritic cells(pDCs),CLEC9A^+DCs,natural killer(NK)cells,and plasma cells were significantly associated with improved survival outcomes in NPC.Taken together,our findings represent a unique resource providing in-depth insights into the cellular heterogeneity of NPC TME and highlight potential biomarkers for anticancer treatment and risk stratification,laying a new foundation for precision therapies in NPC. | Yu-Pei Chen Jian-Hua Yin Wen-Fei Li Han-Jie Li Dong-Ping Chen Cui-Juan Zhang Jia-Wei Lv Ya-Qin Wang Xiao-Min Li Jun-Yan Li Pan-Pan Zhang Ying-Qin Li Qing-Mei He Xiao-Jing Yang Yuan Lei Ling-Long Tang Guan-Qun Zhou Yan-Ping Mao Chen Wei Ke-Xu Xiong Hong-Bo Zhang Shi-Da Zhu Yong Hou Ying Sun Michael Dean Ido Amit Kui Wu Dong-Ming Kuang Gui-Bo Li Na Liu Jun Ma | 2020 | Cell Research2020，30，11： | 19 |
| 17 | Nuclear factor-kappaB activation on the reactive oxygen species in acute necrotizing pancreatitic rats显示文摘AIM: To investigate the potential role of nuclear factor kappa-B (NF-κB) activation on the reactive oxygen species in rat acute necrotizing pancreatitis (ANP) and to assess the effect of pyrrolidine dithiocarbamate (PDTC, an inhibitor of NF-κB).METHODS: Rat ANP model was established by retrograde injection of 5% sodium taurocholate into biliopancreatic duct. Rats were randomly assigned to three groups (10rats each): Control group, ANP group and PDTC group. At the 6th h of the model, the changes of the serum amylase,nitric oxide (NO), malondialdehyde (MDA), superoxide dismutase (SOD) and pancreatic morphological damage were observed. The expressions of inducible nitric oxide (iNOS) were observed by SP immunohistochemistry. And the expressions of NF-κB p65 subunit mRNA were observed by hybridization in situ.RESULTS: Serum amylase and NO level decreased significantly in ANP group as compared with PDTC administrated group [(7 170.40±1 308.63) U/L vs(4 074.10±1 719.78) U/L,P<0.05], [(76.95±9.04) μmol/L vs (65.18±9.02) μmol/L,P<0.05] respectively. MDA in both ANP and PDTC group rose significantly over that in control group [(9.88±1.52)nmol/L, (8.60±1.41) nmol/L, vs (6.04±1.78) nmol/L,P<0.05], while there was no significant difference between them. SOD levels in both ANP and PDTC group underwent a significant decrease as compared with that in control [(3 214.59±297.74) NU/mL, (3 260.62±229.44) NU/mL,vs (3 977.80±309.09) NU/mL, P<0.05], but there was no significant difference between them. Though they were still higher than those in Control group, pancreas destruction was slighter in PDTC group, iNOS expression and NF-κB p65 subunit mRNA expression were lower in PDTC group as compared with ANP group.CONCLUSION: We conclude that correlation among NF-κB activation, serum amylase, reactive oxygen species level and tissue damage suggests a key role of NF-κB in the pathogenesis of ANP. Inhibition of NF-κB activation may reverse the pancreatic damage of rat ANP and the production of reactive oxygen species. | Jin Long Na Song Xi-Ping Liu Ke-Jian Guo Ren-Xuan Guo | 2005 | World Journal of Gastroenterology2005，11，27： | 18 |
| 18 | HuoguⅠformula prevents steroid-induced osteonecrosis in rats by down-regulating PPARγ expression and activating Wnt/LRP5/β-catenin signaling显示文摘OBJECTIVE: To investigate the effects of HuoguⅠformula on regulation of lipid metabolism in steroid-induced osteonecrosis of the femoral head(SONFH) rats and verify our hypothesis that HuoguⅠ formula regulates lipid metabolism by down-regulating peroxisome proliferator-activated receptor gamma(PPARγ) expression and activating Wnt signaling pathways.METHODS: Eighty-five rats were divided into four groups: control, model, Huogu 15 g/kg and Huogu30 g/kg. Six weeks later, animals were anaesthetized, femora were dissected for histopathological examination of the osteonecrotic changes and repair processes, micro computed tomography(Micro-CT)-based micro-angiography was performed to assess vascularization. Serum lipid levels were detected by haematological examination. The expressions of PPARγ, Wnt3a, low density lipoprotein receptor-related protein 5(LRP5) and β-catenin were evaluated by immunohistochemistry,Western blot and quantitative real-time polymerase chain reaction analyses.RESULTS: The incidence of osteonecrosis, ratio of empty lacuna, adipose tissue area and adipocyte perimeter in the bone marrow were dramatically lower in the Huogu Ⅰ formula treatment groups.Bymicro-CTquantification,HuoguⅠformulatreatment dose-dependently increased vessel volume,vessel surface, percentage of vessel volume and vessel thickness of the femoral heads of SONFH rats. Levels of serum lipid in Huogu 15 g/kg and Huogu 30 g/kg groups reduced significantly.HuoguⅠformula treatment could suppress the expression of PPARγ and increase the expressions of Wnt3a, LRP5 and β-catenin at both protein and mRNA levels.CONCLUSION: The results of our present study highlight the lipid-lowering potential of Huogu Ⅰformula, and provide further evidence of the involvement of the PPARγ inhibition and Wnt/LRP5/β-catenin signaling activation in the effects of HuoguⅠformula. | Yini Jiang Daobing Liu Xiangying Kong Ying Xu Weiheng Chen Na Lin | 2014 | Journal of Traditional Chinese Medicine2014，34，3： | 18 |
| 19 | Combined Transplantation of Neural Stem Cells and Olfactory Ensheathing Cells Improves the Motor Function of Rats with Intracerebral Hemorrhage显示文摘Objective To investigate the effects of combined transplantation of neural stem cells (NSC) and olfactory ensheathing cells(OEC)on the motor function of rats with intracerebral hemorrhage.Methods In three days after a rat model of caudate nucleus hemorrhage was established,NSCs and OEC,NSC,OEC (from embryos of Wistar rats)or normal saline were injected into hematomas of rats in combined transplantation group,NSC group,OEC group,and control group,respectively.Damage of neural function was scored before and in 3,7,14,30 days after operation.Tissue after transplantation was observed by immunocytochemistry staining.Results The scores for the NSC,OEC and co-transplantation groups were significantly lower in 14 and 30 days after operation than in 3 days after operation(P<0.05).The scores for the NSC and OEC groups were significantly lower than those for the control group only in 30 days after operation(P<0.05),while the difference for the NSC-OEC group was significant in 14 days after operation(P<0.05).Immunocytochemistry staining revealed that the transplanted OEC and NSC could survive,migrate and differentiate into neurons,astrocytes,and oligodendrocytes.The number of neural precursor cells was greater in the NSC and combined transplantation groups than in the control group.The number of neurons differentiated from NSC was significantly greater in the co-transplantation group than in the NSC group.Conclusion Co-transplantation of NSC and OEC can promote the repair of injured tissue and improve the motor function of rats with intracerebral hemorrhage. | ZHOU-PING TANG XUE-WEI XIE YUAN-HONG SHI NA LIU SuI-QIANG ZHU ZAI-WANG LI YUN CHEN | 2010 | Biomedical and Environmental Sciences2010，23，1： | 17 |
