1Biostratigraphy of Triassic Marine Reptiles in Southwest Guizhou and Its Adjacent Area显示文摘This paper briefly reviews the Triassic marine reptile fossils inGuizhou Province, especially the fossils that have been recently found in the Guanling area. Based on three sections at Guanling and Xingyi, Guizhou Province and Luoping, Yunnan Province, four horizons with vertebrate fossils are recognized in the Middle and Upper Triassic of this area; They are from bottom to top: Member I and Member Ⅱ of the Guanling Formation, and the Zhuganpo Member and the Wayao Member of the Falang Formation.WANG Liting, LI Jinling, WANG Xinjin, LI Chun,WU Tianzhuang and LIU Jun Bureau of Geology and Mineral Exploration and Development of Guizhou ProvinceGuiyang 550004 Institute of Vertebrate Palaeontology and Palaeoanthropology,Chinese Academy of Sciences, Beijing 100044 Guizhou Museum, Guiyang 550004 2001Acta Geologica Sinica(English Edition)2001,75,4:17
2NLRP3-dependent pyroptosis is required for HIV-1 gp120- induced neuropathology显示文摘The human immunodeficiency virus-1(HIV-1)envelope protein gp120 is the major contributor to the pathogenesis of HIVassociated neurocognitive disorder(HAND).Neuroinflammation plays a pivotal role in gp120-induced neuropathology,but how gp120 triggers neuroinflammatory processes and subsequent neuronal death remains unknown.Here,we provide evidence that NLRP3 is required for gp120-induced neuroinflammation and neuropathy.Our results showed that gp120-induced NLRP3-dependent pyroptosis and IL-1βproduction in microglia.Inhibition of microglial NLRP3 inflammasome activation alleviated gp120-mediated neuroinflammatory factor release and neuronal injury.Importantly,we showed that chronic administration of MCC950,a novel selective NLRP3 inhibitor,to gp120 transgenic mice not only attenuated neuroinflammation and neuronal death but also promoted neuronal regeneration and restored the impaired neurocognitive function.In conclusion,our data revealed that the NLRP3 inflammasome is important for gp120-induced neuroinflammation and neuropathology and suggest that NLRP3 is a potential novel target for the treatment of HAND.Xiaolong He Weijun Yang Zhijie Zeng Yi Wei Jie Gao Bao Zhang Li Li Liqun Liu Yu Wan Qing Zeng Zelong Gong Liting Liu Hanyun Zhang Yubin Li Shaojie Yang Tongtong Hu Lixian Wu Eliezer Masliah Shenghe Huang Hong Cao 2020Cellular & Molecular Immunology2020,17,3:11
3Focal adhesion protein Kindlin-2 regulates bone homeostasis in mice显示文摘Our recent studies demonstrate that the focal adhesion protein Kindlin-2 is critical for chondrogenesis and early skeletal development. Here, we show that deleting Kindlin-2 from osteoblasts using the 2.3-kb mouse Col1 a1-Cre transgene minimally impacts bone mass in mice, but deleting Kindlin-2 using the 10-kb mouse Dmp1-Cre transgene, which targets osteocytes and mature osteoblasts, results in striking osteopenia in mice. Kindlin-2 loss reduces the osteoblastic population but increases the osteoclastic and adipocytic populations in the bone microenvironment. Kindlin-2 loss upregulates sclerostin in osteocytes,downregulates β-catenin in osteoblasts, and inhibits osteoblast formation and differentiation in vitro and in vivo. Upregulation ofβ-catenin in the mutant cells reverses the osteopenia induced by Kindlin-2 deficiency. Kindlin-2 loss additionally increases the expression of RANKL in osteocytes and increases osteoclast formation and bone resorption. Kindlin-2 deletion in osteocytes promotes osteoclast formation in osteocyte/bone marrow monocyte cocultures, which is significantly blocked by an anti-RANKLneutralizing antibody. Finally, Kindlin-2 loss increases osteocyte apoptosis and impairs osteocyte spreading and dendrite formation.Thus, we demonstrate an important role of Kindlin-2 in the regulation of bone homeostasis and provide a potential target for the treatment of metabolic bone diseases.Huiling Cao Qinnan Yan Dong Wang Yumei Lai Bo Zhou Qi Zhang Wenfei Jin Simin Lin Yiming Lei Liting Ma Yuxi Guo Yishu Wang Yilin Wang Xiaochun Bai Chuanju Liu Jian QFeng Chuanyue Wu Di Chen Xu Cao Guozhi Xiao 2020Bone Research2020,8,1:8
4Restudy of the storage and migration model of the Quaternary groundwater in Beijing Plain area显示文摘Through a wide-spread groundwater sampling mainly at nested monitoring wells in the Beijing Plain area,combined with data collection,the study analyzes water level,hydrochemistry,temperature,tritium,deuterium,18O,14C and other aspects,and indicates that there exits an obvious stratification phenomenon of the groundwater in the alluvial plain area down in the middle part of alluvial-pluvial fans,and the hydraulic connection between layers is very weak.The analysis of the tritium concentration suggests that the average influence depth of the modern precipitation is approximately 120m.Based on the analysis of the 22 paleowater samples through the D18O method and 14C isotopic dating,the deep groundwater circulation in the fine sediments area of Beijing Plain down in the fringe part of alluvial-pluvial fans is relatively slow.On average the paleowater point occurs approximately below the 180m at these points.The main reasons for the formation of stratification and paleowater points are the water-blocking effect of the clay type strata and the compaction effect during the sedimentary process,especially the differential compaction,which could form closed or relatively closed stagnant aquifers.Groundwater in this kind of stagnant aquifers to some degree belongs to non-renewable resource,and should be reconsidered and re-arranged in the water resources management strategy.LIU YuanZhang WU Qiang LIN Pei LIU JiuRong XING LiTing GAO ZhiHui 2012Science China Earth Sciences2012,55,7:7
5Famitinib in combination with concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma: a phase 1, open-label, dose-escalation Study显示文摘Background:Famitinib is a tyrosine kinase inhibitor against multiple targets,including vascular endothelial growth factor receptor 2/3,platelet-derived growth factor receptor,and stem cell factor receptor(c-kit).Previous studies have demonstrated anti-tumour activities of famitinib against a wide variety of advanced-stage solid cancers.We aimed to determine the safety and efficacy of famitinib with concurrent chemoradiotherapy(CCRT)in patients with locoregionally advanced nasopharyngeal carcinoma(NPC).We also evaluated the feasibility of contrast-enhanced ultrasound(D-CEUS)as a predictor of early tumour response to famitinib and to correlate functional parameters with clinical efficacy.Methods:The trial was conducted in subjects with stage III or IVa-b NPC using a 3+3 design of escalating fami-tinib doses.Briefly,subjects received 2 weeks of famitinib monotherapy followed by 7 weeks of famitinib plus CCRT.D-CEUS of the neck lymph nodes was performed at day 0,8 and 15 after famitinib was administered before starting concurrent chemoradiotherapy.End points included safety,tolerability and anti-tumour activity.Results:Twenty patients were enrolled(six each for 12.5,16.5 and 20 mg and two for 25 mg).Two patients in the 25 mg cohort developed dose-limiting toxicities,including grade 4 thrombocytopenia and grade 3 hypertension.The most common grade 3/4 adverse events were leukopenia,neutropenia and radiation mucositis.D-CEUS tests showed that more than 60%of patients achieved a perfusion parameter response after 2 weeks taking famitinib alone,and the parameter response was associated with disease improvement.In the famitinib monotherapy stage,three patients(15%)showed partial responses.The complete response rate was 65%at the completion of treatment and 95%3 months after the treatment ended.After a median follow-up of 44 months,the 3-year progression-free survival(PFS)and distant metastasis-free survival were 70%and 75%,respectively.Subjects with a decrease of perfusion parameter response,such as peak intensity decreased at least 30%after 1 week of famitinib treatment,had higher 3-year PFS(90.9%vs.44.4%,95%CI 73.7%-100%vs.11.9%-76.9%,P<0.001)than those with an increase or a reduction of less than 30%.Conclusions:The recommended famitinib dose for phase II trial is 20 mg with CCRT for patients with local advanced NPC.D-CEUS is a reliable and early measure of efficacy for famitinib therapies.Further investigation is required to confirm the effects of famitinib plus chemoradiotherapy.Qiuyan Chen Linquan Tang Na Liu Feng Han Ling Guo Shanshan Guo Jianwei Wang Huai Liu Yanfang Ye Lu Zhang Liting Liu Pan Wang Yingqin Li Qingmei He Xiaoqun Yang Qingnan Tang Yang Li YuJing Liang XueSong Sun Chuanmiao Xie Yunxian Mo Ying Guo Rui Sun Haoyuan Mo Kajia Cao Xiang Guo Musheng Zeng Haiqiang Mai Jun Ma 2018Cancer Communications2018,38,1:6
6Liquid metal as reconnection agent for peripheral nerve injury显示文摘This study demonstrated an unconventional way to cure peripheral nerve injury(PNI) with liquid metal gallium employed as the reconnection agent. In vivo experiments were performed, in which transected sciatic nerve of mouse was reconnected by liquid metal gallium.The nerve signals detected was found to be almost the same as those from the complete nerve, where the negative bursting firing caused by PNI was absent on the neural discharge curve after nerve-reconnection surgery. Meanwhile the atrophy tendency of gastrocnemius muscle was distinctly procrastinated according to the results of pathological examinations, which showed fibrillation potentials emerged immediately for mice with PNI but did not emerge until the third month for those received nerve-reconnection surgery. Furthermore, physical properties of gallium were studied, showing that its impedance was slightly influenced by the frequency of transmitted signal and the temperature, which confirmed the stability of gallium in future clinical usage. This technology is expected to perform well in clinical surgery for PNI and even central nervous system injury in the coming time.Fujun Liu Yongze Yu Liting Yi Jing Liu 2016Science Bulletin2016,61,12:4
7Effects of Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) medicated serum on chemotactic migration of alveolar macrophages and inters regions macrophages in rats显示文摘OBJECTIVE: To observe the effects of serum containing Mahuang(Herba Ephedra Sinica) or Wuweizi(Fructus Schisandrae Chinensis) on the migration of alveolar macrophages(AM) and interstitial macrophages(IM) from normal rats, and to analyze and compare the mechanisms leading to cell migration differences.METHODS: Rats were randomly divided into three groups: Mahuang(Herba Ephedra Sinica), Wuweizi(Fructus Schisandrae Chinensis), and blank serum. After treatment with the herbs, serum was extracted from the rats. AM and IM were isolated from normal rats and cultured. The effects of Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) medicated serum on normal rat AM and IM chemotactic migration were determined by transwell assays. The CC chemokine receptor(CCR) 2, CCR5, voltage-gated Kvl. 3 K^+channel(Kv1. 3), and voltage-gated Kvl. 5 K^+channel(Kv1. 5) protein levels were analyzed by western blotting.RESULTS: The migration quantities of AM and IM in the Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) medicated serum groups were significantly higher than those in the blank serum group(P < 0.01). Compared with the Wuweizi(Fructus Schisandrae Chinensis) medicated serum group, the migration quantity of cultured rat AM in the Mahuang(Herba Ephedra Sinica) medicated serum group was significantly increased(P <0.01). Meanwhile, compared with the Mahuang(Herba Ephedra Sinica) medicated serum group, the migration quantity of cultured rat IM in the Wuweizi(Fructus Schisandrae Chinensis) medicated serum group was significantly increased(P < 0.01).CCR2, CCR5, Kv1. 3, and Kv1. 5 proteins were expressed on the AM cell surface, and showed significantly higher expression in the Mahuang(Herba Ephedra Sinica) medicated serum group compared with the Wuweizi(Fructus Schisandrae Chinensis)medicated serum group. In contrast, CCR5, Kv1.3,and Kv1.5 proteins were expressed on the IM cell surface, and showed significantly higher expression in the Wuweizi(Fructus Schisandrae Chinensis)medicated serum group compared with the Mahuang(Herba Ephedra Sinica) medicated serum group.CONCLUSION: Mahuang(Herba Ephedra Sinica)and Wuweizi(Fructus Schisandrae Chinensis) can promote AM and IM migration ability, with Mahuang(Herba Ephedra Sinica) targeting AM more apparently and Wuweizi(Fructus Schisandrae Chinensis) targeting IM more apparently. The mechanism may be that, by stimulating cells, Mahuang(Herba Ephedra Sinica) and Wuweizi(Fructus Schisandrae Chinensis) promote expression of CCR2 and CCR5 receptors on the AM and IM cell surface,which pass signals to Kvl.3 and Kvl.5 ion channels,leading to changes in the cytoskeleton, and ultimately promoting chemotactic cell migration.Yuan Yiping Zhai Huaqiang Zhang Tian Guo Zhaojuan Kong Liting Jia Xiaoyu Wang Ningning Dai Ying Liu Guoxiu Wang Yanping 2017Journal of Traditional Chinese Medicine2017,37,5:3
8Synthesis of Chitosan-Hydroxyapatite Composites and Its Effect on the Properties of Bioglass Bone Cement显示文摘Chitosan-hydroxyapatite(CS-HA) composite powders were synthesized via in situ co-precipitation method,through the reaction of Ca(NO3)2 and H3PO4 in the simulated body fluid(SBF) containing appropriate amount of chitosan.The thermal evolution,microstructure and morphology were studied by TG-DTA(thermogravimetry-differential thermal analysis),XRD(X-ray diffraction),FTIR(Fourier transform infrared spectroscopy) and TEM(transmission electron microscopy).The in vitro bioactivity test showed that the obtained CS-HA composites had higher capability of inducing calcium ions deposition.Effects of CS-HA composites on the bioactivity and compressive strength of bioglass bone cement were investigated.The results indicated that the bioactivity of bioglass bone cement could be improved further when CS-HA composite powders were added into the cement,and appropriate amount of CS-HA additive was favorable for compressive strength improvement of bioglass bone cement.Jingxiao Liu Fei Shi Ling Yu Liting Niu Shanshan Gao 2009Journal of Materials Science & Technology2009,25,4:3
9Single-cell transcriptomes of peripheral blood cells indicate and elucidate severity of COVID-19显示文摘The blood and immune system of coronavirus disease 2019(COVID-19)infected patients are dysfunctional,and numerous studies have been conducted to resolve their characteristics and pathogenic mechanisms.Nevertheless,the variations of immune responses along with disease severity have not been comprehensively documented.Here,we profiled the single-cell transcriptomes of 96,313 peripheral blood mononuclear cells(PBMCs)derived from 12 COVID-19 patients(including four moderate,four severe and four critical cases)and three healthy donors.We showed that proliferative CD8 effector T cells with declined immune functions and cytotoxicity accumulated in the critical stage.By contrast,the quantity of natural killer(NK)cells was significantly reduced,while they exhibited enhanced immune activities.Notably,a gradually attenuated responseto COVID-19 along with disease severity was observed in monocytes,in terms of cellular composition,transcriptional discrepancy and transcription factor regulatory network.Furthermore,we identified immune cell-type dependent cytokine signatures distinguishing the severity of COVID-19 patients.In addition,cell interactions between CD8 effector T/NK cells and monocytes mediated by inflammatory cytokines were enhanced in moderate and severe stages,but weakened in critical cases.Collectively,our work uncovers the cellular and molecular players underlying the disordered and heterogeneous immune responses associated with COVID-19 severity,which could provide valuable insights for the treatment of critical COVID-19 patients.Xiaowei Xie Xuelian Cheng Gaoxiang Wang Biao Zhang Mengyao Liu Liting Chen Hui Cheng Sha Hao Jianfeng Zhou Ping Zhu Tao Cheng 2021Science China(Life Sciences)2021,64,10:3
10Iodine biofortification of vegetable plants-An innovative method for iodine supplementation显示文摘To elevate the iodine level in edible plants has been shown to be an excellent approach to correct iodine deficiency.We have proposed an innovative approach to produce iodine supplementation by growing vegetables on soils with algal-based iodized organic fertilizer.Ten species of vegetables were tested.The biological absorption and migration of the iodine within the vegetable plants were revealed using microscopy with silver iodide precipitation technique.The results show that the absorption of iodine by the vegetable increases with increasing amount of the algal-based iodized organic fertilizer in general.And the uptake of iodine by leaf vegetable is significantly greater than that by fruit vegetable.Distribution of iodine in various plant organs shows a trend of decreasing iodine concentration from root,leaf,stalk,to fruit.A similar of decreasing concentration can also be found in various cells(cytoplasm>cytoderm>organelles).The exploration of the iodine uptake and biogeochemistry migration mechanisms provides an important scientific foundation for establishing a new method of producing a natural iodine supplementation by iodine biofortification of vegetables.WENG HuanXin HONG ChunLai XIA TianHong BAO LiTing LIU HuiPing LI DeWang 2013Chinese Science Bulletin2013,58,18:3
11Global analysis of lysine succinylation in patchouli plant leaves显示文摘Lysine succinylation is a novel,naturally occurring posttranslational modification(PTM)in living organisms.Global lysine succinylation identification has been performed at the proteomic level in various species;however,the study of lysine succinylation in plant species is relatively limited.Patchouli plant(P.cablin(Blanco)Benth.,Lamiaceae)is a globally important industrial plant and medicinal herb.In the present study,lysine succinylome analysis was carried out in patchouli plants to determine the potential regulatory role of lysine succinylation in patchouli growth,development,and physiology.The global succinylation sites and proteins in patchouli plants were screened with an immunoprecipitation affinity enrichment technique and advanced mass spectrometry-based proteomics.Several bioinformatic analyses,such as function classification and enrichment,subcellular location predication,metabolic pathway enrichment and protein−protein interaction networking,were conducted to characterize the functions of the identified sites and proteins.In total,1097 succinylation sites in 493 proteins were detected in patchouli plants,among which 466 succinylation sites in 241 proteins were repeatedly identified within three independent experiments.The functional characterization of these proteins indicated that the tricarboxylic acid(TCA)cycle,oxidative phosphorylation,photosynthesis processes,and amino acid biosynthesis may be regulated by lysine succinylation.In addition,these succinylated proteins showed a wide subcellular location distribution,although the chloroplast and cytoplasm were the top two preferred cellular components.Our study suggested the important role of lysine succinylation in patchouli plant physiology and biology and could serve as a useful reference for succinylation studies in other medicinal plants.Xiaobing Wang Xiuzhen Chen Junren Li Xuanxuan Zhou Yanting Liu Liting Zhong Yun Tang Hai Zheng Jiyun Liu Ruoting Zhan Likai Chen 2019Horticulture Research2019,6,1:2

17Understanding the role of interface in advanced semiconductor nanostructure and its interplay with wave function overlap显示文摘As the proportion of interfaces increases rapidly in nanomaterials,properties and quality of interfaces hugely impact the performance of advanced semiconductors.Here,the effect of interfaces is explored by comparatively studying two InAs/AlSb superlattices with and without the thin InAsSb layers inserted inside each InAs layers.Through strain mapping,it indicates that the addition of interfaces leads to an increase of local strain both near interfaces and inside layers.Meantime,owing to the creation of hole potential wells within the original electron wells,the charge distribution undergoes an extra electron-hole alternating arrangement in the structure with inserted layers than the uninserted counterpart.Such a feature is verified to enhance electron-hole wave function overlap by theoretical simulations,which is a must for better optical performance.Furthermore,with an elaborate design of the inserted layers,the wave function overlap could be boosted without sacrificing other key device performances.Chenyuan Cai Yunhao Zhao Faran Chang Xuebing Zhao Liting Yang Chongyun Liang Guowei Wang Zhichuan Niu Yi Shi Xianhu Liu Yuesheng Li Renchao Che 2020Nano Research2020,13,6:1
