1Correlation between tongue manifestations and glucose, total cholesterol, and high-density lipoprotein cholesterol in patients with acute cerebral infarction显示文摘OBJECTIVE: To analyze the association between tongue manifestations and the levels of glucose (GLU), total cholesterol(TCH), and high-density lipoprotein cholesterol(HDL-C) in subjects with acute cerebral infarction.METHODS: Hospitalized patients with first unilateral cerebral infarction in the Neurological Department of Xuanwu Hospital were included and the correlation between tongue fur color, fur nature,and the levels of GLU,TCH, HDL-C were analyzed.RESULTS: HDL level in the thin fur group was higher than that in the thick fur group(P=0.02). The difference in the levels of GLU,TCH, and HDL-C among the groups was significant(P<0.05), classified in terms of slippery, moist, and dry fur. Further comparison between the groups by Student-Newman-Keuls test showed that GLU level in the dry fur group was the highest. Moreover, the TCH level in the slippery fur group was higher than the other two groups.CONCLUSION: A correlation between tongue manifestations and GLU, TCH, HDL-C was identified in the patients with acute cerebral infarction.Ping Liu Li Gao Juexian Song Haiping Zhao XiaoguangWu Liyuan Huang Pingping Wang Yumin Luo 2014Journal of Traditional Chinese Medicine2014,34,2:14
2Toxicity of graphene oxide and multi-walled carbon nanotubes against human cells and zebrafish显示文摘Graphene possesses unique physical and chemical properties, which have inspired a wide range of potential biomedical applications. However, little is known about the adverse effects of graphene on the human body and ecological environment. The purpose of our work is to make assessment on the toxicity of graphene oxide (GO) against human cell line (human bone marrow neuroblastoma cell line and human epithelial carcinoma cell line) and zebrafish (Danio rerio) by comparing the toxic effects of GO with its sister, multi-walled carbon nanotubes (MWNTs). The results show that GO has a moderate toxicity to organisms since it can induce minor (about 20%) cell growth inhibition and slight hatching delay of zebrafish embryos at a dosage of 50 mg/L, but did not result in significant increase of apoptosis in embryo, while MWNTs exhibit acute toxicity leading to a strong inhibition of cell proliferation and serious morphological defects in developing embryos even at relatively low concentration of 25 mg/L. The distinctive toxicity of GO and MWNTs should be ascribed to the different models of interaction between nanomaterials and organisms, which arises from the different geometric structures of nanomaterials. Collectively, our work suggests that GO does actual toxicity to organisms posing potential environmental risks and the result is also shedding light on the geometrical structure-dependent toxicity of graphitic nanomaterials.CHEN LiQiang HU PingPing ZHANG Li HUANG SiZhou LUO LingFei HUANG ChengZhi 2012Science China Chemistry2012,55,10:12

4Variations in silicate concentration affecting photosynthetic carbon fixation by spring phytoplankton assemblages in surface water of the Strait of Malacca显示文摘The Strait of Malacca (SoM), the world's busiest sea-route, is increasingly polluted as the rapid development of world trades, affecting phytoplankton primary productivity therein. The variations of surface phytoplankton biomass, size-structure and carbon fixation were investigated across the SoM during the spring period (May 4 to 9, 2011). Chlorophyll a concentration increased from 0.12 μg/L at the northwest entrance of the SoM to a maximal 0.63 μg/L at narrowest section, and decreased to 0.10 μg/L at the southeast entrance. Photosynthetic carbon fixation by phytoplankton coincided well with Chl a biomass, and increased from 10.8 to 22.3 μg C/(L d), then decreased to 9.21 μg C/(L d); while the carbon fixation rate showed an inverse pattern to the changes of Chl a, and decreased from 87.1 to 35.5 μg C/(μg Chl a d) and increased thereafter to 95.3 μg C/(μg Chla·d). Picophytoplankton cells (<3 μm) contributed to more than 60% and 50% of the total Chl a and carbon fixation at both the entry waters; while the contributions of pico-cells decreased sharply to the minimum of 18.3% and 27.5% at the narrowest part of the SoM. In particular, our results showed that the silicate concentration positively regulated Chl a biomass and carbon fixation, reflecting that the higher silicate favoured the growth of phytoplankton and thus led to higher primary production in this strait.LI Gang LIN Qiang SHEN Pingping NI Guangyan SONG Xingyu WANG Shengfu FAN Yanzhi HUANG Liangmin TAN Yehui 2013Acta Oceanologica Sinica2013,32,4:4
5Association of serum lipids and severity of epithelial ovarian cancer:an observational cohort study of 349 Chinese patients显示文摘While obesity and fat intake have been associated with the risk and prognosis of epithelial ovarian cancer, the association between the lipid levels and epithelial ovarian cancer phenotype remains controversial. We conducted a retrospective study of 349 epithelial ovarian cancer patients who received treatment at Jiangsu Cancer Hospital, China between 2011 and 2017. We analyzed age at diagnosis, blood pressure, plasma glucose content, body mass index(BMI), lipid levels and clinical parameters. Severity of epithelial ovarian cancer was classified according to the International Federation of Gynecology and Obstetrics(FIGO) grading system. Univariate analysis of the clinical factors according to the severity of epithelial ovarian cancer was followed by logistic regression analysis to identify clinical factors significantly associated with epithelial ovarian cancer severity. Univariate analysis indicated that age,BMI, triglyceride(TG), and high density lipoproteins(HDL) differed significantly among different stages of epithelial ovarian cancer(P<0.05). In the logistic regression model, elevated TG(OR: 1.883; 95% CI= 1.207-2.937), and low HDL(OR: 0.497; 95% CI = 0.298-0.829) levels were significantly associated with the high severity epithelial ovarian cancer. Our data indicate that high TG and low HDL levels correlate with a high severity of epithelial ovarian cancer. These data provide important insight into the potential relationship between the lipid pathway and epithelial ovarian cancer phenotype and development.Yi Zhang Jing Wu Junya Liang Xing Huang Lei Xia Dawei Ma Xinyu Xu Pingping Wu 2018The Journal of Biomedical Research2018,32,5:3
6Complementary DNA sequencing (cDNA): an eff ective approach for assessing the diversity and distribution of marine benthic ciliates along hydrographic gradients显示文摘The Yellow Sea Cold Water Mass(YSCWM)is a distinct hydrographic phenomenon of the Yellow Sea,and the distribution pattern of meio-and macrobenthos diff ers inside and outside of the YSCWM.However,such a pattern has never been observed in the microbenthic ciliate communities.Therefore,we hypothesized that benthic ciliates followed a similar distribution pattern as meio-and macrobenthos,but this pattern has not been uncovered by morphological methods.We evaluated the diversity and distribution of benthic ciliates at fi ve stations along hydrographic gradients across the YSCWM and adjacent shallow water by using morphology and DNA and complementary DNA(cDNA)high-throughput sequencing of the V4 region of 18S rRNA gene.Results showed that the diversity of benthic ciliates detected by DNA(303 OTUs),and the cDNA(611 OTUs)sequencing was much higher than that detected by the morphological method(79 species).Morphological method detected roughly diff erent ciliate communities inside and outside of the YSCWM,but without statistical signifi cance.No clear pattern was obtained by DNA sequencing.In contrast,cDNA sequencing revealed a distinct distribution pattern of benthic ciliate communities like meioand macrobenthos,which coincided well with the results of the environmental parameter analysis.More than half of the total sequences detected by DNA sequencing belonged to planktonic ciliates,most(if not all)of which were recovered from historic DNA originating through the sedimentation of pelagic forms because none of them were observed morphologically.The irrelevant historic DNA greatly infl uenced the recovery of rare species and thus limited the understanding of the benthic ciliate diversity and distribution.Our research indicates that the methods used have signifi cant eff ects on the investigation of benthic ciliate communities and highlights that cDNA sequencing has great advantages in estimating the diversity and distribution of benthic ciliates,as well as the potential for benthic environmental assessments.Pingping HUANG Feng ZHAO Kuidong XU 2021Journal of Oceanology and Limnology2021,39,1:3
7Composition and Distribution of Planktonic Ciliates in the Southern South China Sea During Late Summer: Comparison Between Surface and 75 m Deep Layer显示文摘Ciliates are very important components in most marine ecosystem.They are trophic link between the microbial food web and grazing food chain.In this study,ciliates were collected from 11 sites in the southern South China Sea(SCS) during August 25 to September 28,2011.Their composition and distribution at the surface and 75 m deep depth of the ocean were studied.A total of 30 species belonging to 22 genera were identified,and 22 species of 15 genera were Tintinnids.Eutintinnus fraknoii and E.stramentus were the most common species.The other dominants were strombidiids ciliates including Strombidium conicum and S.globosaneum,which were followed by the tide form,Mesodinium pulex.Ciliates abundance ranged from 46 ind L^(-1) to 368 ind L^(-1) in the open sites,46–368 ind L^(-1) at surface and 73–198 ind L^(-1) at 75 m deep layer.In the Yongshu reef,ciliates abundance ranged from 167 ind L^(-1) to 365 ind L^(-1) in the water column,similar to that in Sanya coral reef waters.Ciliates composition showed obvious difference between surface and 75 m deep layer at station S2(P < 0.05),while no similar result was observed at other sites.At 75 m deep layer,salinity was negatively related to mixed layer depth(P < 0.05),but positively to chlorophyll a concentration(P < 0.05),indicating that the change of vertical mixing in water column influenced vertical distribution of ciliates in the southern SCS.LIU Huaxue SHEN Pingping LI Chunhou CHEN Zuozhi QI Zhanhui HUANG Honghui 2016Journal of Ocean University of China2016,15,1:3
8Improved Denoising Autoencoder for Maritime Image Denoising and Semantic Segmentation of USV显示文摘Unmanned surface vehicle(USV)is currently a hot research topic in maritime communication network(MCN),where denoising and semantic segmentation of maritime images taken by USV have been rarely studied.The former has recently researched on autoencoder model used for image denoising,but the existed models are too complicated to be suitable for real-time detection of USV.In this paper,we proposed a lightweight autoencoder combined with inception module for maritime image denoising in different noisy environments and explore the effect of different inception modules on the denoising performance.Furthermore,we completed the semantic segmentation task for maritime images taken by USV utilizing the pretrained U-Net model with tuning,and compared them with original U-Net model based on different backbone.Subsequently,we compared the semantic segmentation of noised and denoised maritime images respectively to explore the effect of image noise on semantic segmentation performance.Case studies are provided to prove the feasibility of our proposed denoising and segmentation method.Finally,a simple integrated communication system combining image denoising and segmentation for USV is shown.Yuhang Qiu Yongcheng Yang Zhijian Lin Pingping Chen Yang Luo Wenqi Huang 2020China Communications2020,17,3:2
9Longitudinal patterns of spring-intermonsoon phytoplankton biomass,species compositions and size structure in the Bay of Bengal显示文摘Vertical distributions of phytoplankton biomass,compositions and size structure were investigated during the spring-intermonsoon (April 22 to 30) of 2010 along transact 10 N of the Bay of Bengal,northern Indian Ocean.Surface phytoplankton biomass (Chl a) was (0.065 ± 0.009) μg/L,being greater than 80% of which was contributed by pico-phytoplankton (<3 μm).The Chl a concentration vertically increased to the maximal values at deep chlorophyll maximum (DCM) layer that shoaled eastwards from 75 to 40 m.The Chl a biomass at DCM layer generally varied between 0.2 and 0.4 μg/L,reaching the maximum of 0.56 μg/L with micro-phytoplankton cells (>20 μm) accounting for 58% and nano-(3-20 μm) or pico-cells for 15% and 27%,respectively.In particular,the cells concentration coupling well with phosphate level was observed at middle layer (75-100 m) of 87 to 89 E,dominated by micro-cells diatoms (e.g.,Chaetoceros atlanticus v.neapolitana,Chaetoceros femur and Pseudonitzschia sp.) and cyanobacteria (i.e.,Trichodesmium hildebrandtii),with the cells concentration reached as high as 4.0 × 10 4 and 4.3 × 10 4 cells/L.At the rest of the transact however,dinoflagellates (e.g.,Amphisdinium carterae and Prorocentrum sp.) were the dominant species,with the cells concentration varying from 0.3 × 10 3 to 6.8 × 10 3 cells/L.Our results also indicate that the regulation of large cells (micro-,nano-) on phytoplankton biomass merely occurred at DCM layer of the Bay.LI Gang KE Zhixin LIN Qiang NI Guangyan SHEN Pingping LIU Huaxue YIN Jianqiang LI Kaizhi HUANG Liangmin TAN Yehui 2012Acta Oceanologica Sinica2012,31,2:2
10rtcisE2F promotes the self-renewal and metastasis of liver tumorinitiating cells via N^(6)-methyladenosine-dependent E2F3/E2F6 mRNA stability显示文摘Liver cancer is highly heterogeneous,and the tumor tissue harbors a variety of cell types.Liver tumor initiating cells(TICs)well contribute to tumor heterogeneity and account for tumor initiation and metastasis,but the molecular mechanisms of liver TIC self-renewal are elusive.Here,we identified a functional read-through rt-circRNA,termed rtcisE2F,that is highly expressed in liver cancer and liver TICs.rtcisE2F plays essential roles in the self-renewal and activities of liver TICs.rtcisE2F targets E2F6 and E2F3 mRNAs,attenuates mRNA turnover,and increases E2F6/E2F3 expression.Mechanistically,rtcisE2F functions as a scaffold of N^(6)-methyladenosine(m^(6)A)reader IGF2BP2 and E2F6/E2F3 mRNA.rtcisE2F promotes the association of E2F6/E2F3 mRNAs with IGF2BP2,and inhibits their association with another m^(6)A reader,YTHDF2.IGF2BP2 inhibits E2F6/E2F3 mRNA decay,whereas YTHDF2 promotes E2F6/E2F3 mRNA decay.By switching m^(6)A readers,rtcisE2F enhances E2F6/E2F3 mRNA stability.E2F6 and E2F3 are both required for liver TIC self-renewal and Wnt/β-catenin activation,and inhibition of these pathways is a potential strategy for preventing liver tumorigenesis and metastasis.In conclusion,the rtcisE2F-IGF2BP2/YTHDF2-E2F6/E2F3-Wnt/β-catenin axis drives liver TIC self-renewal and initiates liver tumorigenesis and metastasis,and may provide a strategy to eliminate liver TICs.Zhenzhen Chen Lan Huang Kaili Wang Lulu Zhang Xiang Zhong Zhongyi Yan Benyu Liu Pingping Zhu 2022Science China(Life Sciences)2022,65,9:2
11Optimized Fault Detection Algorithm Aided by BDS Baseband Signal for Train Positioning显示文摘The satellite navigation integrity monitoring technology is closely related to the reliability of train positioning.It is of great significance to study satellite navigation Receiver autonomous int egrity mon辻o ring(RAIM)algorithm suitable for train positioning.Some existing conventional RAIM algorithms do not consider the influence of satellite navigation signal on algorithms performance.Aiming at the influence of sat ellite naviga tion signal on the propagation processes,such as shadow and multipa th effec ts,the fault detection algor辻hm based on BeiDou navigation satellite system(BDS)baseband signal is proposed.The innovation parameters contained in the satellite navigation baseband signal are combined into the covariance matrix to set up a new test statistics of RAIM.A new fault detection algorithm based on optimized BDS baseband signal is discussed.And combined with weighted least square method,the noise power balance factor is established to realize sat ellite fault det ection.Experimen tai resul ts show that the proposed algorithm can improve the monitoring performance of train satellite positioning integrity,and lay the foundation for meeting the railway industry's security requirements for positioning services.WANG Ershen YANG Di WANG Chuanyun Huang Yufeng QU Pingping PANG Tao 2020Chinese Journal of Electronics2020,29,1:2
12Comprehensive identification of lysine 2-hydroxyisobutyrylated proteins in Ustilaginoidea virens reveals the involvement of lysine 2-hydroxyisobutyrylation in fungal virulence显示文摘Lysine 2-hydroxyisobutyrylation(Khib) is a newly identified post-translational modification(PTM) that plays important roles in transcription and cell proliferation in eukaryotes. However, its function remains unknown in phytopathogenic fungi. Here,we performed a comprehensive assessment of Khibin the rice false smut fungus Ustilaginoidea virens, using Tandem Mass Tag(TMT)-based quantitative proteomics approach. A total of 3 426 Khibsites were identified in 977 proteins, sugg esting that Khibis a common and complex PTM in U. virens. Our data demonstrated that the2-hydroxyisobutyrylated proteins are involved in diverse biological processes. Network analysis of the modified proteins revealed a highly interconnected protein network that included many well-studied virulence factors. We confirmed that the Zn-binding reduced potassium dependency3-type histone deacetylase(UvRpd3) is a major enzyme that removes 2-hydroxyisobutyrylation and acetylation in U. virens. Notably, mutations of Khib sites in the mitogen-activated protein kinase(MAPK)UvSlt2 significantly reduced fungal virulence and decreased the enzymatic activity of UvSlt2. Molecular dynamics simulations demonstrated that 2-hydroxyisobutyrylation in UvSlt2 increased the hydrophobic solvent-accessible surface area and thereby affected binding between the UvSlt2 enzyme and its substrates. Our findings thus establish Khibas a major post-translational modification in U. virens and point to an important role for Khibin the virulence of this phytopathogenic fungus.Xiaoyang Chen Xiabing Li Pingping Li Xiaolin Chen Hao Liu Junbin Huang Chaoxi Luo Tom Hsiang Lu Zheng 2021Journal of Integrative Plant Biology2021,63,2:2
