| 1 | Long-term effects of mowing on plasticity and allometry of Leymus chinensis in a temperate semi-arid grassland,China显示文摘Mowing is an important land management practice for natural semi-arid regions.A growing body of empirical evidence shows that different mowing regimes affect the functioning of grassland ecosystems.However,the responses of plant functional traits to long-term mowing and their allometric scaling under long-term mowing are poorly understood.For a better understanding of the effects of mowing on grassland ecosystems,we analyzed the allometric traits of leaves and stems of Leymus chinensis(Trin.) Tzvel.,a dominant grass species in eastern Eurasian temperate grassland,at different mowing intensities(no clipping,clipping once every two years,once a year and twice a year).Experiments were conducted on plots established over a decade ago in a typical steppe of Xilinhot,Inner Mongolia,China.Results showed that most of the functional traits of L.chinensis decreased with the increased mowing intensity.The responses of leaves and stems to long-term mowing were asymmetric,in which leaf traits were more stable than stem traits.Also significant allometric relationships were found among most of the plant functional traits under the four mowing treatments.Sensitive traits of L.chinensis(e.g.leaf length and stem length) were primary indicators associated with aboveground biomass decline under high mowing intensity.In conclusion,the allometric growth of different functional traits of L.chinensis varies with different long-term mowing practices,which is likely to be a strategy used by the plant to adapt to the mowing disturbances. | LI Xiliang HOU Xiangyang REN Weibo Taogetao BAOYIN LIU Zhiying Warwick BADGERY LI Yaqiong WU Xinhong XU Huimin | 2016 | Journal of Arid Land2016，8，6： | 7 |

| 3 | Bloodletting at Jing-well points decreases interstitial fluid flow in the thalamus of rats显示文摘OBJECTIVE: To investigate the changes in the neuronal microenvironment of the middle cerebral artery(MCA) territory induced by Jing-well points bloodletting acupuncture(WPBA) and to explore the neuroprotective mechanism of WPBA in stroke.METHODS: Adult male Sprague Dawley(n = 32)rats were randomly divided into four groups of eight animals each: WPBA-thalamus group(WT),WPBA-caudate nucleus group(WC), sham-control thalamus group(ST) and sham-control caudate nucleus group(SC). Animals in the WT and WC groups received 2 μL of the extracellular tracer gadolinium-diethylene triamine pentaacetic acid(Gd-DTPA)injected into the thalamus or caudate nucleus, respectively, and 12 Jing-well points in the distal ends of the rats' digits were used for WPBA. Although 2 μL of Gd-DTPA was injected into the thalamus or caudate nucleus, respectively, for animals in the two sham groups(ST and SC), no acupuncture or bloodletting was performed. Brain extracellular space and interstitial fluid flow parameters were measured using Gd-DTPA-enhanced magnetic resonance imaging.RESULTS: The brain interstitial fluid flow speed was decreased in the thalamus after WPBA, with a significantly lower Gd-DTPA clearance rate and longer half-life of Gd-DTPA in the thalamus of treated rats than those in sham-control rats [WPBA-treated rats' clearance rate,(7.47 ± 3.15) × 10^(-5)/s(P = 0.009);half-life,(1.52 ± 0.13) h, P = 0.000]. By contrast, no significant changes in brain extracellular space and interstitial fluid flow parameters were detected in the caudate nucleus after WPBA(P = 0.649). In addition, no differences in the morphology of the brain extracellular space or the final distribution of the traced brain interstitial fluid were demonstrated between the WT and WC groups(P = 0.631, P = 0.970,respectively).CONCLUSION: The WPBA decreased the speed of the local thalamic ISF flow in rats, which is assumed to be a beneficial protection by down-modulated the metabolic rate of the attacked neurons under stroke. | FuYu LiYuliang GuoJia Liu Bin Liu Huipo Zhang Weibo Sun Wanli GaoYajuan Ren Qiushi Han Haojun | 2016 | Journal of Traditional Chinese Medicine2016，36，1： | 3 |
| 4 | Gut microbiota from end-stage renal disease patients disrupt gut barrier function by excessive production of phenol显示文摘End stage renal disease (ESRD), an advanced stage of chronic kidney disease, has received increasing attention as a leading public health problem (Webster et al., 2017). Chronic kidney disease (CKD) and ESRD are invariably accompanied by chronic systemic inflammation which plays central roles in CKD progression (Cachofeiro et al., 2008) and the increased mortality due to cardiovascular disease (Landray et al., 2004). | Xifan Wang Yanling Hao Xiaoxue Liu Shoujuan Yu Weibo Zhang Songtao Yang Zhengquan Yu Fazheng Ren | 2019 | Journal of Genetics and Genomics2019，46，8： | 3 |

| 6 | Screening and identifying natural products with SARS-CoV-2 infection inhibitory activity from medicinal fungi显示文摘The coronavirus disease of 2019(COVID‐19),a global pandemic caused by the severe acute respiratory syndrome coronavirus 2(SARS‐CoV‐2),can result in severe health complications.In addition to physical preventative measures,pharmaceutical intervention is also crucial.Numerous natural products from medicinal fungi have shown promise as potential antiviral drugs and may serve as a source of effective components with antiviral activity against SARS‐CoV‐2 and other coronaviruses.In this study,we developed a workflow that integrates viral infection inhibition assays at both cellular and molecular levels,as well as molecular separation and characterization,to screen and identify natural products with antiviral activity.Using this workflow,we screened 167 extracts extracted from 36 medicinal fungi using optimized extraction methods.We assessed the antiviral effects of these extracts by measuring their ability to inhibit SARS‐CoV‐2 infection and receptor binding domain‐human angiotensin‐converting enzyme 2(RBD‐hACE2)binding in vitro.Following charge‐and size‐based characterization of the active compounds through filtration and chromatographic fractionation,mass spectrometry characterization of the fractionated compounds revealed that the active components are polysaccharides and determined their monosaccharide residue composition.Our findings provide new insights into the antiviral potential of natural products and their screening strategies and may contribute to the development of effective antiviral therapeutics against COVID‐19 and other diseases. | Shuang Zhao Amelia Siqi Huang Weibo Zhang Lili Ren Hexiang Wang Jianbin Wang Xinyang Shao Guanbo Wang | 2024 | Biosafety and Health2024，6，1： | 0 |
