3Third generation of vortex identification methods:Omega and Liutex/Rortex based systems显示文摘A vortex is intuitively recognized as the rotational/swirling motion of fluids,but a rigorous and universally-accepted definition is still not available.Vorticity tube/filament has been regarded equivalent to a vortex since Helmholtz proposed the concepts of vorticity tube/filament in 1858 and the vorticity-based methods can be categorized as the first generation of vortex identification methods.During the last three decades,a lot of vortex identification methods,including 0,A,and Aci criteria,have been proposed to overcome the problems associated with the vorticity-based methods.Most of these criteria are based on the Cauchy-Stokes decomposition and/or eigenvalues of the velocity gradient tensor and can be considered as the second generation of vortex identification methods.Starting from 2014,the Vortex and Turbulence Research Team at the University of Texas at Arlington(the UTA team)focus on the development of a new generation of vortex identification methods.The first fruit of this effort,a new Omega(/2)vortex identification method,which defined a vortex as a connected region where the vorticity overtakes the deformation,was published in 2016.In 2017 and 2018,a Liutex(previously called Rortex)vector was proposed to provide a mathematical definition of the local rigid rotation part of the fluid motion,including both the local rotational axis and the rotational strength.Liutex/Rortex is a new physical quantity with scalar,vector and tensor forms exactly representing the local rigid rotation of fluids.Meanwhile,a decomposition of the vorticity to a rotational part namely Liutex/Rortex and an anti-symmetric shear part(RS decomposition)was introduced in 2018,and a universal decomposition of the velocity gradient tensor to a rotation part(7?)and a non-rotation part(NR、was also given in 2018 as a counterpart of the traditional Cauchy-Stokes decomposition.Later in early 2019,a Liutex/Rortex based Omega method called Omega-Liutex,which combines the respective advantages of both Liutex/Rortex and Omega methods,was developed.And a latest objective Omega method,which is still under development,is also briefly introduced.These advances are classified as the third generation of vortex identification methods in the current paper.To elaborate the advantages of the third-generation methods,six core issues for vortex definition and identification have been raised,including:(1)the absolute strength,(2)the relative strength,(3)the rotational axis,(4)the vortex core center location,(5)the vortex core size,(6)the vortex boundary.The new third generation of vortex identification methods can provide reasonable answers to these questions,while other vortex identification methods fail to answer all questions except for the approximation of vortex boundaries.The purpose of the current paper is to summarize the main ideas and methods of the third generation of vortex identification methods rather than to conduct a comprehensive review on the historical development of vortex identification methods.Chaoqun Liu Yi-sheng Gao Xiang-rui Dong Yi-qian Wang Jian-ming Liu Yu-ning Zhang Xiao-shu Cai Nan Gui 2019Journal of Hydrodynamics2019,31,2:82

6Distribution and assessment of heavy metals in the surface sediment of Yellow River, China显示文摘Large amounts of heavy metals discharged by industrial cities that are located along the middle reach of Yellow River, China have detrimental impacts on both the ecological environment and human health. In this study, fourteen surface sediment samples were taken in the middle reach of the Yellow River. Contents of Zn, Pb, Ni, Cu, Cr, Cd, As were measured, and the pollution status was assessed using three widely used pollution assessment methods, including the single factor index method, Nemerow pollution index method and potential ecological risk index. The concentrations of the studied heavy metals followed the order: Zn > Cr > Cu > Ni > Pb > As > Cd. Nearly 50% of sites had Cu and Cr accumulation. The concentration of Cu at the Yiluo River exceeded the secondary standard value of the Environmental quality standard for soils. Comparison of heavy metal concentrations between this study and other selected rivers indicated that Cu and Cr may be the major pollutants in our case. The single factor index indicated that many samples were at high levels of pollution for Cu and Cd; the Nemerow pollution index indicated that the Yihe River, Luohe River, Yiluo River and Huayuankou were polluted. According to the results of potential ecological risk assessment, Cd in the tributaries of Luo River, Yihe River,and Yiluo River showed high risk toward the ecosystem and human health, Cd in Huanyuankou and Cu in Yiluo River showed a middle level of risk and other samples were at a low level of risk.Nan Yan Wenbin Liu Huiting Xie Lirong Gao Ying Han Mengjing Wang Haifeng Li 2016Journal of Environmental Sciences2016,28,1:33
7New incompatible pair of TCM:Epimedii Folium combined with Psoraleae Fructus induces idiosyncratic hepatotoxicity under immunological stress conditions显示文摘Epimedii Folium(EF)combined with Psoraleae Fructus(PF)is a common modern preparation,but liver injury caused by Chinese patent medicine preparations containing EF and PF has been frequently reported in recent years.Zhuangguguanjiewan pills(ZGW),which contain EF and PF,could induce immune idiosyncratic liver injury according to clinical case reports and a nonhepatotoxic dose of lipopolysaccharide(LPS)model.This present study evaluated the liver injury induced by EF or PF alone or in combination and investigated the related mechanism by using the LPS model.Liver function indexes and pathological results showed that either EF or PF alone or in combination led to liver injury in normal rats;however,EF or PF alone could lead to liver injury in LPS-treated rats.Moreover,EF combined with PF could induce a greater degree of injury than that caused by EF or PF alone in LPS-treated rats.Furthermore,EF or PF alone or in combination enhanced the LPS-stimulated inflammatory cytokine production,implying that IL-1β,which is processed and released by activating the NLRP3 inflammasome,is a specific indicator of EF-induced immune idiosyncratic hepatotoxicity.Thus,EF may induce liver injury through enhancing the LPS-mediated proinflammatory cytokine production and activating the NLRP3 inflammasome.In addition,the metabolomics analysis results showed that PF affected more metabolites in glycerophospholipid and sphingolipid metabolic pathways compared with EF in LPS model,suggesting that PF increased the responsiveness of the liver to LPS or other inflammatory mediators via modulation of multiple metabolic pathways.Therefore,EF and PF combination indicates traditional Chinese medicine incompatibility,considering that it induces idiosyncratic hepatotoxicity under immunological stress conditions.Yuan Gao Zhilei Wang Jinfa Tang Xiaoyi Liu Wei Shi Nan Qin Xiaoyan Wang Yu Pang Ruisheng Li Yaming Zhang Jiabo Wang Ming Niu Zhaofang Bai Xiaohe Xiao 2020Frontiers of Medicine2020,14,1:32

9Correlation of matrix metalloproteinase suppressor genes RECK,VEGF,and CD105 with angiogenesis and biological behavior in esophageal squamous cell carcinoma显示文摘AIM: To explore the expression of reversion inducing cysteine-rich protein with Kazal motifs (RECK), vascular endothelial growth factor (VEGF) and endoglin (CD105) protein and its correlation with occurrence, development, invasion and metastasis in esophageal squamous cell carcinoma (ESCC). METHODS: Streptavidin-peroxidase (SP) immunohisto- chemistry was used to detect expression of RECK and VEGF in 62 cases of ESCC, 31 cases of adjacent atypical hyperplastic epithelium and 62 cases of normal esophageal epithelium. CD105 Mb was used to assess microvessel density (MVD). RESULTS: The expression of RECK was closely correlated with histological grade, infiltrative depth and lymphatic metastasis in ESCC (P < 0.05). The expression of RECK decreased during cancer development: normal esophageal epithelium (85.5%, 53/62), adjacent atypical hyperplastic epithelium (71.0%, 22/31), and carcinoma (59.7%, 37/62). There was a significant difference among the groups (P < 0.05). The expression of VEGF protein was closely correlated with infiltrative depth and lymphatic metastasis in ESCC (P < 0.05). The expression of VEGF protein increased during cancer development: normal esophageal epithelium (29.0%, 18/62), adjacent atypical hyperplastic epithelium (54.8%, 17/31), and carcinoma (67.7%, 42/62). There was a significant difference among the groups (P < 0.05). MVDCD105 increased in accordance with histological grade, butthere was no significant difference (grade Ⅰ, 36.92 ± 10.85; grade Ⅱ, 37.65 ± 9.50; and grade Ⅲ, 38.06 ± 12.19). The MVDCD105 was closely correlated with infiltration and lymphatic metastasis in ESCC (P < 0.05). The expression of RECK was inversely correlated with the expression of VEGF and CD105. CONCLUSION: RECK, VEGF and CD105 play important roles in the infiltration, metastasis and carcinogenesis in esophageal carcinoma. Angiogenesis in ESCC may be promoted by over-expression of CD105.Sheng-Lei Li, Zhi-Hua Zhao, Dong-Ling Gao, Zong-Wen Liu, Qiu-Min Zhao, Jin-Xia Yu, Kui-Sheng Chen, Yun-Han Zhang, Department of Pathology, The First Affiliated Hospital Zhengzhou University He’nan Key Laboratory of Tumor Pathology, Zhengzhou 450052, He’nan Province, China 2007World Journal of Gastroenterology2007,13,45:30

11The Chromosome-Level Reference Genome of Tea Tree Unveils Recent Bursts of Nonautonomous LTR Retrotransposons in Driving Genome Size Evolution显示文摘Dear Editor,The tea tree Camellia sinensis,a member of the genus Camellia in the Theaceae family,includes two major cultivated varieties,C.sinensis var.assamica(CSA\Assam type)and C.sinensis var.sinensis(CSS;Chinese type)(Ming and Bartholomew,2007).Due to the high economic importance of the tea tree,considerable efforts have been made to explore genetic basis of the biosynthesis of natural metabolites that determine health benefits and diverse tea flavors(Shi et al.,2011;Li et al.,2011;Li et al.,2015;Xia et aL,2017;Liu et al.,2019).Qun-Jie Zhang Wei L i Kui Li Hong Nan Cong Shi Yun Zhang Zhang-Yan Dai Yang-Lei Lin Xiao-Lan Yang Yan Tong Dan Zhang Cui Lu Li-Ying Feng Chen-Feng Wang Xiao-Xin Liu Jian-An Huang Wen-Kai Jiang Xing-Hua Wang Xing-Cai Zhang Evan E.Eichler Zhong-Hua Liu and Li-Zhi Gao 2020Molecular Plant2020,13,7:27
12Blockade of Tim-3 Pathway Ameliorates Interferon-γ Production from Hepatic CD8^+ T Cells in a Mouse Model of Hepatitis B Virus Infection显示文摘T cell immunoglobulin-and mucin-domain-containing molecule-3(Tim-3) has been reported to participate in the pathogenesis of inflammatory diseases. However,whether Tim-3 is involved in hepatitis B virus(HBV) infection remains unknown. Here,we studied the expression and function of Tim-3 in a hydrodynamics-based mouse model of HBV infection. A significant increase of Tim-3 expression on hepatic T lymphocytes,especially on CD8+ T cells,was demonstrated in HBV model mice from day 7 to day 18. After Tim-3 knockdown by specific shRNAs,significantly increased IFN-γ production from hepatic CD8+ T cells in HBV model mice was observed. Very interestingly,we found Tim-3 expression on CD8+ T cells was higher in HBV model mice with higher serum anti-HBs production. Moreover,Tim-3 knockdown influenced anti-HBs production in vivo. Collectively,our data suggested that Tim-3 might act as a potent regulator of antiviral T-cell responses in HBV infection.Ying Ju Nan Hou Xiaoning Zhang Di Zhao Ying Liu Jinjin Wang Fang Luan Wei Shi Faliang Zhu Wensheng Sun Lining Zhang Chengjiang Gao Lifen Gao Xiaohong Liang Chunhong Ma 2009Cellular & Molecular Immunology2009,6,1:19
13Cardamonin from a medicinal herb protects against LPS-induced septic shock by suppressing NLRP3 inflammasome显示文摘Aberrant activation of NLRP3 inflammasome has been implicated in the pathogenesis of diverse inflammation-related diseases, and pharmacological molecules targeting NLRP3 inflammasome are of considerable value to identifying potential therapeutic interventions. Cardamonin(CDN), the major active ingredient of the traditional Chinese medicinal herb Alpinia katsumadai, has exerted an excellent anti-inflammatory activity, but the mechanism underlying this role is not fully understood. Here, we show that CDN blocks canonical and noncanonical NLRP3 inflammasome activation triggered by multiple stimuli. Moreover, the suppression of CDN on inflammasome activation is specific to NLRP3, not to NLRC4 or AIM2 inflammasome. Besides, the inhibitory effect is not dependent on the expression of NF-κB-mediated inflammasome precursor proteins. We also demonstrate that CDN suppresses the NLRP3 inflammasome through blocking ASC oligomerization and speckle formation in a dose-dependent manner.Importantly, CDN improves the survival of mice suffering from lethal septic shock and attenuates IL-1βproduction induced by LPS in vivo, which is shown to be NLRP3 dependent. In conclusion, our results identify CDN as a broad-spectrum and specific inhibitor of NLRP3 inflammasome and a candidate therapeutic drug for treating NLRP3 inflammasome-driven diseases.Zhilei Wang Guang Xu Yuan Gao Xiaoyan Zhan Nan Qin Shubin Fu Ruisheng Li Ming Niu Jiabo Wang Youping Liu Xiaohe Xiao Zhaofang Bai 2019Acta Pharmaceutica Sinica B2019,9,4:19
14Chinese Tuina Downregulates the Elevated Levels of Tissue Plasminogen Activator in Sciatic Nerve Injured Sprague-Dawley Rats显示文摘Objective:To elucidate the mechanism of Chinese tuina in treating sciatic nerve crush injury,and to detect the levels of tissue plasminogen activator(t PA)and plasminogen activator inhibitor-1(PAI-1),which is thought to play an important role in nerve regeneration.Methods:Thirty-two adult male Sprague-Dawley rats were subjected to sciatic nerve crush injury and 16 rats(sham-operated group)went through a sham operation.Control group was given no treatment while tuina group received tuina therapy since day 7 post-surgery.Tuina treatment was performed once a day and lasted for 20 days.The sciatic functional index was examined every 5days during the treatment session.The rats'gastrocnemius muscles were evaluated for changes in mass and immunohistochemistry techniques were performed to detect the levels of tP A and PAI-1.Results:Tuina therapy improved the motor function of sciatic nerve injured rats(P<0.05),however,it did not increase muscle volume(P<0.05).Tuina downregulated the levels of t PA and PAI-1(P<0.05).Conclusions:The present study implies that tuina treatment could accelerate rehabilitation of peripheral nerve injury.PAN Fan YU Tian-yuan Steven Wong XIAN Si-tong LU Meng-qian WU Jian-cong GAO Yu-feng LI Xiao-qin GENG Nan YAO Bin-bin 2017Chinese Journal of Integrative Medicine2017,23,8:16
15MicroRNA-663 induces immune dysregulation by inhibiting TGF-β1 production in bone marrow-derived mesenchymal stem cells in patients with systemic lupus erythematosus显示文摘Mesenchymal stem cells(MSCs)are critical for immune regulation.Although several microRNAs(miRNAs)have been shown to participate in autoimmune pathogenesis by affecting lymphocyte development and function,the roles of miRNAs in MSC dysfunction in autoimmune diseases remain unclear.Here,we show that patients with systemic lupus erythematosus(SLE)display a unique miRNA signature in bone marrow-derived MSCs(BMSCs)compared with normal controls,among which miR-663 is closely associated with SLE disease activity.MiR-663 inhibits the proliferation and migration of BMSCs and impairs BMSC-mediated downregulation of follicular T helper(Tfh)cells and upregulation of regulatory T(Treg)cells by targeting transforming growth factorβ1(TGF-β1).MiR-663 overexpression weakens the therapeutic effect of BMSCs,while miR-663 inhibition improves the remission of lupus disease in MRL/lpr mice.Thus,miR-663 is a key mediator of SLE BMSC regulation and may serve as a new therapeutic target for the treatment of lupus.Linyu Geng Xiaojun Tang Kangxing Zhou Dandan Wang Shiying Wang Genhong Yao Weiwei Chen Xiang Gao Wanjun Chen Songtao Shi Nan Shen Xuebing Feng Lingyun Sun 2019Cellular & Molecular Immunology2019,16,3:16
16The Chromosome-Based Rubber Tree Genome Provides New Insights into Spurge Genome Evolution and Rubber Biosynthesis显示文摘The rubber tree,Hevea brasiliensis,produces natural rubber that serves as an essential industrial raw material.Here,we present a high-quality reference genome for a rubber tree cultivar GT1 using single-molecule real-time sequencing(SMRT)and Hi-C technologies to anchor the~1.47-Gb genome assembly into 18 pseudochromosomes.The chromosome-based genome analysis enabled us to establish a model of spurge chromosome evolution,since the common paleopolyploid event occurred before the split of Hevea and Manihot.We show recent and rapid bursts of the three Hevea-specific LTR-retrotransposon families during the last 10 million years,leading to the massive expansion by~65.88%(~970 Mbp)of the whole rubber tree genome since the divergence from Manihot.We identify large-scale expansion of genes associated with whole rubber biosynthesis processes,such as basal metabolic processes,ethylene biosynthesis,and the activation of polysaccharide and glycoprotein lectin,which are important properties for latex production.A map of genomic variation between the cultivated and wild rubber trees was obtained,which contains~15.7 million high-quality single-nucleotide polymorphisms.We identified hundreds of candidate domestication genes with drastically lowered genomic diversity in the cultivated but not wild rubber trees despite a relatively short domestication history of rubber tree,some of which are involved in rubber biosynthesis.This genome assembly represents key resources for future rubber tree research and breeding,providing novel targets for improving plant biotic and abiotic tolerance and rubber production.Jin Liu Cong Shi Cheng-Cheng Shi Wei Li Qun-Jie Zhang Yun Zhang Kui Li Hui-Fang Lu Chao Shi Si-Tao Zhu Zai-Yun Xiao Hong Nan Yao Yue Xun-Ge Zhu Yu Wu Xiao-Ning Hong Guang-Yi Fan Yan Tong Dan Zhang Chang-Li Mao Yun-Long Liu Shi-Jie Hao Wei-Qing Liu Mei-Qi Lv Hai-Bin Zhang Yuan Liu Ge-Ran Hu-tang Jin-Peng Wang Jia-Hao Wang Ying-Huai Sun Shu-Bang Ni Wen-Bin Chen Xing-Cai Zhang Yuan-Nian Jiao Evan E.Eichler Guo-Hua Li Xin Liu Li-Zhi Gao 2020Molecular Plant2020,13,2:15
17Chemical fertilizers could be completely replaced by manure to maintain high maize yield and soil organic carbon(SOC)when SOC reaches a threshold in the Northeast China Plain显示文摘The combined use of chemical and organic fertilizers is considered a good method to sustain high crop yield and enhance soil organic carbon(SOC),but it is still unclear when and to what extent chemical fertilizers could be replaced by organic fertilizers.We selected a long-term soil fertility experiment in Gongzhuling,Northeast China Plain to examine the temporal dynamics of crop yield and SOC in response to chemical nitrogen,phosphorus,and potassium(NPK) fertilizers and manure,applied both individually and in combination,over the course of three decades(1980-2010).We aimed to test 1) which fertilizer application is the best for increasing both maize yield and SOC in this region,and 2) whether chemical fertilizers can be replaced by manure to maintain high maize yield and enhance SOC,and if so,when this replacement should be implemented.We observed that NPK fertilizers induced a considerable increase in maize yield in the first 12 years after the initiation of the experiment,but manure addition did not.In the following years,the addition of both NPK fertilizers and manure led to an increase in maize yield.SOC increased considerably in treatments with manure but remained the same or even declined with NPK treatments.The increase in maize yield induced by NPK fertilizers alone declined greatly with increasing SOC,whereas the combination of NPK and manure resulted in high maize yield and a remarkable improvement in SOC stock.Based on these results we suggested that NPK fertilizers could be at least partially replaced by manure to sustain high maize yield after SOC stock has reached 41.96 Mg C ha^(-1) in the Northeast China Plain and highly recommend the combined application of chemical fertilizers and manure(i.e.,60 Mg ha^(-1)).LI Hui FENG Wen-ting HE Xin-hua ZHU Ping GAO Hong-jun SUN Nan XU Ming-gang 2017Journal of Integrative Agriculture2017,16,4:13
18Triptolide Inhibits Expression of Inflammatory Cytokines and Proliferation of Fibroblast-like Synoviocytes Induced by IL-6/sIL-6R-Mediated JAK2/STAT3 Signaling Pathway显示文摘Triptolide,a component of the Chinese herb Tripterygium wilfordii Hook F,has been proved to be effective in the treatment of rheumatoid arthritis(RA).However,its underlying mechanisms on RA have not yet been well established.We observed the inhibitory effect of triptolide on the expression of inflammatory cytokines and proliferation of fibroblast-like synoviocytes(FLS)induced by the complex of interleukin-6(IL-6)and the soluble form of the IL-6 receptor(sIL-6R).Furthermore,to clarify the underlying mechanisms,we treated FLS with the Janus-activated kinase 2(JAK2)inhibitor/signal transducer and activator of transcription 3(STAT3)activation blocker AZD1480.In this study,immunohistochemical staining was used to identify vimentin(+)and CD68(−)in FLS.The FLS proliferation was measured by cell proliferation assay,and the cell cycles were analyzed by flow cytometry.Furthermore,ELISA was used to detect the expression of the inflammatory factors in culture solution.The expression levels of p-JAK2,JAK2,p-STAT3 and STAT3 were investigated through Western blotting analysis.The results showed that IL-6/sIL-6R significantly increased the cell proliferation and expression of inflammatory cytokines,including IL-6,interleukin-1β(IL-1β)and vascular endothelial growth factor(VEGF).Triptolide or AZD1480 inhibited the cell proliferation and inflammatory cytokine expression in IL-6/sIL-6R-stimulated FLS by suppressing JAK2/STAT3.The study suggested that the physiological effects of triptolide on RA were due to its contribution to the inhibition of the inflammatory cytokine expression and FLS proliferation by suppressing the JAK2/STAT3 signaling pathway.It may provide an innovative insight into the effect of triptolide in preventing RA pathogenesis.Jian-jing LIN Ke TAO Nan GAO Hui ZENG De-li WANG Jun YANG Jian WENG 2021Current Medical Science2021,41,1:13

20Anti-diabetic effects and mechanisms of action of a Chinese herbal medicine preparation JQ-R in vitro and in diabetic KKAy mice显示文摘Refined-JQ(JQ-R) is a mixture of refined extracts from Coptis chinensis(Ranunculaceae),Astragalus membranaceus(Leguminosae) and Lonicera japonica(Caprifoliaceae), the three major herbs of Jin Qi-Jiang Tang tablet, a traditional Chinese medicine(TCM) formula. The mechanisms by which JQ-R regulates glucose metabolism and improves insulin sensitivity were studied in type 2 diabetic KK^(Ay)mice and insulin-resistant L6 myotubes. To investigate the mechanisms by which JQ-R improves insulin sensitivity, a model of insulin-resistant cells induced with palmitic acid(PA) was established in L6 myotubes. Glucose uptake and expression of factors involved in insulin signaling, stress, and inflammatory pathways were detected by immunoblotting. JQ-R showed beneficial effects on glucose homeostasis and insulin resistance in a euglycemic clamp experiment and decreased fasting insulin levels in diabetic KK^(Ay)mice. JQ-R also improved the plasma lipid profiles. JQ-R directly increased the activity of superoxide dismutase(SOD) and decreased malondialdehyde(MDA) as well as inducible nitric oxide synthase(iNOS) levels in insulin-resistant L6 cells, and elevated the insulin-stimulated glucose uptake with upregulated phosphorylation of AKT. The phosphorylation levels of nuclear factor kappa B(NF-κB p65), inhibitor of NF-κB(IκBα), c-Jun N-terminal kinase(JNK1/2) and extracellular-signal-regulated kinases(ERK1/2) were also changed after JQ-R treatment compared with the control group. Together these findings suggest that JQ-R improved glucose and lipid metabolism in diabetic KK^(Ay)mice. JQ-R directly enhanced insulin-stimulated glucose uptake in insulin-resistant myotubes with improved insulin signalling and inflammatory response and oxidative stress. JQ-R could be a candidate to achieve improved glucose metabolism and insulin sensitivity in type 2 diabetes mellitus.Quan Liu Shuainan Liu Lihui Gao Sujuan Sun Yi Huan Caina Li Yue Wang Nan Guo Zhufang Shen 2017Acta Pharmaceutica Sinica B2017,7,4:11
