3Identification of a senescence-related protease in coriander leaves显示文摘Senescence-related protease may play an important role in leaf senescence. By improved SDS-Gela-tin-PAGE assay, a 63 ku senescence-related protease (63 SRP) in coriander leaves was identified. Activity of 63 SRP was increased in parallel to the advance of coriander leaf senescence, and inhibited by treating the leaf with gibberellic acid, and enhanced by ethylene treatment. The 63 SRP was suggested to be a serine protease based on the fact that its activity was inhibited by the protease inhibitor PMSF. The optimal temperature for the activity of the 70 ku protease was 50°C. The maximal activity was observed at pH 6-9, some activity could be observed on the gel slices incubated at pH 5 or 11. The 63 SRP was partly purified by the way of ammonium sulfate precipitation and then gel slicing after gel elec-trophoresis.Weibo Jiang Xiangjuan Zhou Yumei Zhao Pengcheng Liu 2002Chinese Science Bulletin2002,47,13:10
4Physiological effects of weightlessness: countermeasure system development for a long-term Chinese manned spaceflight显示文摘The Chinese space station will be built around 2020. As a national space laboratory, it will offer unique opportunities for studying the physiological effects of weightlessness and the efficacy of the countermeasures against such effects. In this paper, we described the development of countermeasure systems in the Chinese space program. To emphasize the need of the Chinese space program to implement its own program for developing countermeasures, we reviewed the literature on the negative physiological effects of weightlessness, the challenges of completing missions, the development of countermeasure devices, the establishment of countermeasure programs, and the efficacy of the countermeasure techniques in American and Russian manned spaceflights. In addition, a brief overview was provided on the Chinese research and development on countermeasures to discuss the current status and goals of the development of countermeasures against physiological problems associated with weightlessness.Linjie Wang Zhili Li Cheng Tan Shujuan Liu Jianfeng Zhang Siyang He Peng Zou Weibo Liu Yinghui Li 2019Frontiers of Medicine2019,13,2:9

6Long-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 2016Journal of Arid Land2016,8,6:7
7Adjuvant radiotherapy in central hepatocellular carcinoma after narrow-margin hepatectomy:A 10-year real-world evidence显示文摘Objective:A prospective randomized control study investigated the feasibility and efficacy of adjuvant radiotherapy on patients with central hepatocellular carcinoma(HCC)after narrow-margin hepatectomy(<1 cm).This study presents an updated 10-year real-world evidence to further characterize the role of adjuvant radiotherapy.Methods:Patients with central HCC after narrow-margin hepatectomy(<1 cm)were prospectively assigned to adjuvant radiotherapy group and control group.Patients'outcome,adverse events,long-term recurrence and survival rates were investigated.Results:The 1-,5-,and 10-year recurrence-free survival(RFS)rates were 81.0%,43.9%,and 38.7%,respectively in adjuvant radiotherapy group and 71.7%,35.8%,and 24.2%,respectively in control group(log-rank test,P=0.09).The 1-,5-,and 10-year overall survival(OS)rates were 96.6%,54.7%,and 42.8%,respectively in adjuvant radiotherapy group and 90.2%,55.1%,and 30.0%,respectively in control group(log-rank test,P=0.20).The 1-,5-,and 10-year RFS rates for patients with small HCC(≤5 cm)were 91.1%,51.6%,and 48.4%,respectively in adjuvant radiotherapy group and 80.0%,36.6%,and 26.6%,respectively in control group(log-rank test,P=0.03).Landmark analysis demonstrated that patients with small HCC in adjuvant radiotherapy group had a significantly improved OS in second five years after treatment in comparison to patients in control group(log-rank test,P=0.05).Conclusions:Our updated results showed a sustained clinical benefit on reducing recurrence,improving longterm survival for small central HCC by adjuvant radiotherapy after narrow-margin hepatectomy.Long-term survival data also indicated that hepatectomy is an optimal treatment for selected patients with central HCC.Weiqi Rong Weibo Yu Liming Wang Fan Wu Kai Zhang Bo Chen Chengli Miao Liguo Liu Songlin An Changcheng Tao Weihu Wang Jianxiong Wu 2020Chinese Journal of Cancer Research2020,32,5:6

9Elevated plasma levels of selective cytokines in COVID-19 patients reflect viral load and lung injury显示文摘A recent outbreak of pneumonia in Wuhan,China was found to be caused by a 2019 novel coronavirus(2019-nCoV or SARS-CoV-2 or HCoV-19).We previously reported the clinical features of 12 patients with2019-n Co V infections in Shenzhen,China.To further understand the pathogenesis of COVID-19 and find better ways to monitor and treat the disease caused by 2019-n Co V,we measured the levels of 48 cytokines in the blood plasma of those 12 COVID-19 patients.Thirty-eight out of the 48 measured cytokines in the plasma of 2019-n Co V-infected patients were significantly elevated compared to healthy individuals.Seventeen cytokines were linked to 2019-nCoV loads.Fifteen cytokines,namely M-CSF,IL-10,IFN-α2,IL-17,IL-4,IP-10,IL-7,IL-1 ra,G-CSF,IL-12,IFN-γ,IL-1α,IL-2,HGF and PDGF-BB,were strongly associated with the lung-injury Murray score and could be used to predict the disease severity of2019-n Co V infections by calculating the area under the curve of the receiver-operating characteristics.Our results suggest that 2019-nCoV infections trigger extensive changes in a wide array of cytokines,some of which could be potential biomarkers of disease severity of 2019-n Co V infections.These findings will likely improve our understanding of the immunopathologic mechanisms of this emerging disease.Our results also suggest that modulators of cytokine responses may play a therapeutic role in combating the disease once the functions of these elevated cytokines have been characterized.Yingxia Liu Cong Zhang Fengming Huang Yang Yang Fuxiang Wang Jing Yuan Zheng Zhang Yuhao Qin Xiaoyun Li Dandan Zhao Shunwang Li Shuguang Tan Zhaoqin Wang Jinxiu Li Chenguang Shen Jianming Li Ling Peng Weibo Wu Mengli Cao Li Xing Zhixiang Xu Li Chen Congzhao Zhou William J Liu Lei Liu Chengyu Jiang 2020National Science Review2020,7,6:6
10Chemical treatments of the nanocrystalline porous TiO_2 electrodes显示文摘Two types of nanocrystalline porous TiO2 electrodes were prepared by the hydrothermal and painting methods. The incident photon-to-current efficiency and photoelectrical conversion efficiency were both improved by chemical treatments of titanium tetrachloride and titanium isopropoxide. The surface roughness, quantities of adsorbed dye, photocurrent-voltage curves, IR spectra and UV-visible absorption spectra were measured, and the mechanism of chemical treatments was discussed.ZHANG Dongshe, LIU Yao, WANG Weibo & XIAO XuruiLaboratory of Photochemistry, Center for Molecular Science, Institute of Chemistry.

11Enzymatic and chemical mapping of nucleosome distribution in purified micro- and macronuclei of the ciliated model organism, Tetrahymenathermophila显示文摘Genomic distribution of the nucleosome, the basic unit of chromatin, contains important epigenetic information. To map nucleosome distribution in structurally and functionally differentiated micronucleus(MIC) and macronucleus(MAC) of the ciliate Tetrahymena thermophila, we have purified MIC and MAC and performed micrococcal nuclease(MNase) digestion as well as hydroxyl radical cleavage. Different factors that may affect MNase digestion were examined, to optimize mono-nucleosome production. Mono-nucleosome purity was further improved by ultracentrifugation in a sucrose gradient. As MNase concentration increased, nucleosomal DNA sizes in MIC and MAC converged on 147 bp, as expected for the nucleosome core particle. Both MNase digestion and hydroxyl radical cleavage consistently showed a nucleosome repeat length of^200 bp in MAC of Tetrahymena, supporting ~50 bp of linker DNA. Our work has systematically tested methods currently available for mapping nucleosome distribution in Tetrahymena, and provided a solid foundation for future epigenetic studies in this ciliated model organism.Xiao Chen Shan Gao Yifan Liu Yuanyuan Wang Yurui Wang Weibo Song 2016Science China(Life Sciences)2016,59,9:5

13Whole Genome Analyses of Chinese Population and De Novo Assembly of A Northern Han Genome显示文摘To unravel the genetic mechanisms of disease and physiological traits,it requires comprehensive sequencing analysis of large sample size in Chinese populations.Here,we report the primary results of the Chinese Academy of Sciences Precision Medicine Initiative(CASPMI)project launched by the Chinese Academy of Sciences,including the de novo assembly of a northern Han reference genome(NH1.0)and whole genome analyses of 597 healthy people coming from most areas in China.Given the two existing reference genomes for Han Chinese(YH and HX1)were both from the south,we constructed NH1.0,a new reference genome from a northern individual,by combining the sequencing strategies of PacBio,10×Genomics,and Bionano mapping.Using this integrated approach,we obtained an N50 scaffold size of 46.63 Mb for the NH1.0 genome and performed a comparative genome analysis of NH1.0 with YH and HX1.In order to generate a genomic variation map of Chinese populations,we performed the whole-genome sequencing of 597 participants and identified 24.85 million(M)single nucleotide variants(SNVs),3.85 M small indels,and 106,382 structural variations.In the association analysis with collected phenotypes,we found that the T allele of rs1549293 in KAT8 significantly correlated with the waist circumference in northern Han males.Moreover,significant genetic diversity in MTHFR,TCN2,FADS1,and FADS2,which associate with circulating folate,vitamin B12,or lipid metabolism,was observed between northerners and southerners.Especially,for the homocysteine-increasing allele of rs1801133(MTHFR 677T),we hypothesize that there exists a “comfort”zone for a high frequency of 677T between latitudes of 35–45 degree North.Taken together,our results provide a high-quality northern Han reference genome and novel population-specific data sets of genetic variants for use in the personalized and precision medicine.Zhenglin Du Liang Ma Hongzhu Qu Wei Chen Bing Zhang Xi Lu Weibo Zhai Xin Sheng Yongqiao Sun Wenjie Li Meng Lei Qiuhui Qi Na Yuan Shuo Shi Jingyao Zeng Jinyue Wang Yadong Yang Qi Liu Yaqiang Hong Lili Dong Zhewen Zhang Dong Zou Yanqing Wang Shuhui Song Fan Liu Xiangdong Fang Hua Chen Xin Liu Jingfa Xiao Changqing Zeng 2019Genomics, Proteomics & Bioinformatics2019,17,3:4
14Effects of methylphenidate on resting-state brain activity in normal adults: an fMRI study显示文摘Methylphenidate (MPH) is one of the most commonly used stimulants for the treatment of attention deficit hyperactivity disorder (ADHD). Although several studies have evaluated the effects of MPH on human brain activation during specific cognitive tasks using functional magnetic resonance imaging (fMRI), few studies have focused on spontaneous brain activity. In the current study, we investigated the effect of MPH on the intra-regional synchronization of spontaneous brain activity during the resting state in 18 normal adult males. A handedness questionnaire and the Wechsler Adult Intelligence Scale were applied before medication, and a resting-state fMRI scan was obtained 1 h after medication (20 mg MPH or placebo, order counterbalanced between participants). We demonstrated that: (1) there were no significant differences in the performance of behavioral tasks between the MPH and placebo groups; (2) the left middle and superior temporal gyri had stronger MPH-related regional homogeneity (ReHo); and (3) the left lingual gyrus had weaker MPH-related ReHo. Our findings showed that the ReHo in some brain areas changes with MPH compared to placebo in normal adults, even though there are no behavioral differences. This method can be applied to patients with mental illness who may be treated with MPH, and be used to compare the difference between patients taking MPH and normal participants, to help reveal the mechanism of how MPH works.Yihong Zhu Bin Gao Jianming Hua Weibo Liu Yichao Deng Lijie Zhang Biao Jiang Yufeng Zang 2013Neuroscience Bulletin2013,29,1:4
15Bloodletting 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 2016Journal of Traditional Chinese Medicine2016,36,1:3

19An inferred functional impact map of genetic variants in rice显示文摘Interpreting the functional impacts of genetic variants(GVs)is an important challenge for functional genomic studies in crops and next-generation breeding.Previous studies in rice(Oryza sativa)have focused mainly on the identification of GVs,whereas systematic functional annotation of GVs has not yet been performed.Here,we present a functional impact map of GVs in rice.We curated haplotype information for 17397026 GVs from sequencing data of 4726 rice accessions.We quantitatively evaluated the effects of missense mutations in coding regions in each haplotype based on the conservation of amino acid residues and obtained the effects of 918848 non-redundant missense GVs.Furthermore,we generated high-quality chromatin accessibility(CA)data from six representative rice tissues and used these data to train deep convolutional neural network models to predict the impacts of 5067405 GVs for CA in regulatory regions.We characterized the functional properties and tissue specificity of the GV effects and found that large-effect GVs in coding and regulatory regions may be subject to selection in different directions.Finally,we demonstrated how the functional impact map could be used to prioritize causal variants in mapping populations.This impact map will be a useful resource for accelerating gene cloning and functional studies in rice,and can be freely queried in RiceVarMap V2.0(http://ricevarmap.ncpgr.cn).Hu Zhao Jiacheng Li Ling Yang Gang Qin Chunjiao Xia Xingbing Xu Yangmeng Su Yinmeng Liu Luchang Ming Ling-Ung Chen Lizhong Xiong Weibo Xie 2021Molecular Plant2021,14,9:3
20The role of intraoperative electron radiotherapy in centrally located hepatocellular carcinomas treated with narrow-margin (<1 cm) hepatectomy: a prospective, phase 2 study显示文摘Background: Postoperative radiotherapy (RT) is known to play an important role in the treatment of hepatocellular carcinomas (HCCs), but the specific role of intraoperative electron radiotherapy (IOERT) in HCCs remains unclear. The aim of this study was to investigate the safety and efficacy of IOERT in centrally located HCCs treated with narrow-margin (<1 cm) hepatectomy. Methods: This was a single-center, phase 2, prospective non-randomized controlled study, including 268 patients with centrally located HCCs who underwent narrow-margin hepatectomy. The patients were subsequently allocated to the IOERT group (n=59) or to the control group (n=65). The primary outcome of the study was to compare recurrence-free survival (RFS) between the IOERT group and the control group, and the secondary outcome was to compare overall survival (OS) rate between the two groups. Results: Of 268 patients enrolled, a total of 124 were included in the study: 59 in IOERT group, 65 in control group. The 1-, 2-, 3-year RFS rates were 79.3%, 62.1% and 45.8% for patients in the IOERT group, and 47.6%, 28.6%, and 22.9% for patients in the control group, respectively (P=0.025). The 1-, 2-, and 3-year OS rates were 100.0%, 94.9%, and 83.7% for patients in the IOERT group, and 92.3%, 87.5%, and 79.4% for patients in the control group, respectively (P=0.314). Subgroup analysis of MVI (+) patients revealed that RFS and OS are significantly prolonged in the IOERT subgroup as compared to the control, whereas there was no significant difference of RFS and OS between the two groups in MVI (−) patients. Conclusions: IOERT for centrally located HCCs with concurrent narrow-margin hepatectomy was feasible and safe. Statistically better RFS rate was observed in the IOERT group compared to the control group. Subgroup analysis revealed that IOERT was more beneficial for postoperative survival of HCC patients with MVI.
