| 1 | Temporal and Spatial Variations of Abundance of Phycocyaninand Phycoerythrin-Rich Synechococcus in Pearl River Estuary and Adjacent Coastal Area显示文摘Three surveys were carried out in Pearl River Estuary and adjacent coastal area in May, August, and November, 2013, to investigate the temporal and spatial variations of abundance of phycoerythrin-rich Synechococcus(PE-rich SYN) and phycocyanin-rich Synechococcus(PC-rich SYN). The effects of environmental factors on the alternation of the different Synechococcus groups were also elucidated. PE-rich SYN was detected in three surveys, whereas PC-rich SYN was detected in May and August, but not in November. The highest abundances of PE-rich SYN and PC-rich SYN were recorded in August and May, with mean values of 74.17×103 and 189.92×103 cells m L-1, respectively. From May to November, the relative abundance of PE-rich SYN increased, whereas that of PC-rich SYN declined. PE-rich and PC-rich SYN presented similar horizontal distributions with high abundance in the southern estuary in May, and in the western estuary in August. The abundances of PE-rich and PC-rich SYN were high at 27–32℃and salinity of 10–20. PC-rich SYN was not detected at < 24℃, and PC:PE-rich SYN decreased in abundance with salinity increase. When less than 20 mg L-1, suspended particulate matter(SPM) was helpful for Synechococcus growth. PE-rich SYN decreased in abundance when the concentration of dissolved inorganic nitrogen increased in May and November, and the concentration of phosphate increased in November. However, PC-rich SYN abundance and nutrients showed no correlation. Principal component analysis and regression analysis indicated that PE-rich SYN significantly correlated with the principal components that were affected by environmental factors. | JIANG Tao CHAI Chao WANG Jifang ZHANG Ling CEN Jingyi LU Songhui | 2016 | Journal of Ocean University of China2016，15，5： | 6 |
| 2 | Seasonal variation of size-fractionated phytoplankton in the Pearl River estuary显示文摘To investigate the dynamics of phytoplankton size structure in the Pearl River estuary, concentrations of size-fractionated chlorophyll a (Chl a) were determined during four cruises carried out in 2008 and 2010. The distribution of Chl a in this geographical location showed a high degree of temporal variation. Chl a concentrations were highest in autumn, approximately three times higher than those in summer and winter. Microphytoplankton was the dominant contributor, accounting for 66.9% of the Chl a concentration in autumn 2008. In summer and spring 2008, nano-sized cells dominated the phytoplankton population throughout the study region. During the winter cruise, two different areas of water were found, characterized by (1) low salinity and high nutrient content and (2) high salinity and low nutrient content; nano- and picophytoplankton co-dominated the first area, while microphytoplankton dominated the second. It is arguable that grazing could have played a role in determining phytoplankton community size structure in winter. Nutrient concentrations were assumed not to limit phytoplankton growth during the investigation period. Size-differential capacity in competing for the resources available under different hydrodynamic conditions seemed to be the major factor in determining seasonal variation in the structure of the phytoplankton communities. High N:P ratios in the Pearl River estuary had major implications for nutrient pollution control. Our results indicated that studies of phytoplankton size structure provide greater insight into phytoplankton dynamics and are necessary to better manage water quality in the Pearl River estuary. | LI Li LU SongHui JIANG Tao LI Xia | 2013 | Chinese Science Bulletin2013，58，19： | 3 |
| 3 | Response of size-fractionated phytoplankton to environmental factors near the Changjiang Estuary显示文摘Size-based partitioning of phytoplankton is a useful tool for monitoring key phytoplankton traits, and it provides a better understanding of phytoplankton dynamics. Our aim is to determine the variation in the different size classes of phytoplankton to the total phytoplankton biomass during the spring and autumn of 2010 and examine the relationship between phytoplankton size structure and environmental variables and zooplankton community structure near the Changjiang Estuary. In the spring, phytoplankton populations were predominantly consisted of nanophytoplankton throughout the study region. In the autumn, picophytoplankton and nanophytoplankton collectively dominated the phytoplankton community. A Pearson correlation analysis highlighted the role of temperature and trophic conditions on the contributions of nanophytoplankton and picophytoplankton. The grazing pressure exerted by mesozooplankton could have played an important role in determining the microphytoplankton community structure. | Li Li Jingyi Cen Lei Cui Songhui Lu | 2019 | Acta Oceanologica Sinica2019，38，1： | 2 |
| 4 | Identifying human body states by using a flexible integrated sensor显示文摘Flexible sensors are required to be lightweight,compatible with the skin,sufficiently sensitive,and easily integrated to extract various kinds of body vital signs during continuous healthcare monitoring in daily life.For this,a simple and low-cost flexible temperature and force sensor that uses only two carbon fiber beams as the sensing layer is reported in this work.This simple,flexible sensor can not only monitor skin temperature changes in real time but can also extract most pulse waves,including venous waves,from most parts of the human body.A pulse diagnostic glove containing three such flexible sensors was designed to simulate pulse diagnostic methods used in traditional Chinese medicine.Wearable equipment was also designed in which four flexible sensors were fixed onto different body parts(neck,chest,armpit,and fingertip)to simultaneously monitor body temperature,carotid pulse,fingertip artery pulse,and respiratory rate.Four important physiological indicators—body temperature(BT),blood pressure(BP),heart rate(HR),and respiratory rate(RR)—were extracted by the wearable equipment and analyzed to identify exercise,excited,tired,angry,and frightened body states. | Ying Jin Guoning Chen Kete Lao Songhui Li Yong Lu Yufeng Gan Zhundong Li Jiajia Hu Jingcheng Huang Jinxiu Wen Honggui Deng Min Yang Zhiming Chen Xiaoyan Hu Baowen Liang Jianyi Luo | 2020 | npj Flexible Electronics2020，4，1： | 2 |

| 6 | Effects of Ultraviolet(UV)Radiation on Outdoor-and Indoor-Cultured Prorocentrum lima,a Toxic Benthic Dinoflagellate显示文摘The effects of different types of ultraviolet(UV)radiation(UVR,wavelength=280-400 nm)and light intensities on cell growth,pigment composition,UV-absorbing compounds(UVACs),and chlorophyll a(Chl a)fluorescence were studied in dinoflag-ellate Prorocentrum lima cultured outdoors for 16 days and indoors for 18 days.In the outdoor experiment,UVA radiation(320-400 nm)increased the growth rate of this dinoflagellate when solar light intensities were<12%;decreased growth rates were observed when intensities were>12%.Exposure to UVB radiation(280-320 nm)alleviated the negative effects of UVA.In the indoor ex-periment,UVA and low doses of UVB enhanced growth rates.Addition of low doses of UVB to UVA exposure resulted in higher contents of Chl a and photoprotective pigments compared with UVA exposure only.The results of both experiments showed that UVB is the primary signal of UVAC synthesis.High-dose UVB exposure accelerated growth rates when UVAC contents were maintained at high levels,suggesting that the latter plays a key role in UVR damage protection.Furthermore,the repair rate was en-hanced by UVB exposure after 16 days of culture.This study confirms the positive effects of UVA and UVB on the growth of P.lima,with the latter enhancing the photoprotective and recovery pathways of the species. | CHEN Heng HUANG Kaixuan LIU Shasha LU Songhui | 2021 | Journal of Ocean University of China2021，20，3： | 1 |

| 10 | Grazing and performance of the copepod Pseudodiaptomus poplesia on a Chinese strain of Aureococcus anophagefferens显示文摘Brown tides have recurred in estuary areas globally,but trophic interactions between the causative species Aureococcus anophagefferens and planktonic copepods remain poorly understood.In this study,we investigated performance(ingestion,growth,development and reproduction) of the planktonic copepod,Pseudodiaptomus poplesia,offered either mono-algal or mixed-algal diets containing a Chinese strain of A.anophagefferens.A typical Michaelis-Menten pattern existed between ingestion rate and food level when copepod fed on the monoalgal diet of this species.Nauplii exhibited the highest maximum ingestion rate(Imax) than copepodids and adult females.In addition,Imax value was higher in nauplii feeding on A.anophagefferens than on Skeletonema costatum.When fed mixtures of A.anophagefferens and S.costatum,P.poplesia selected against A.anophagefferens cells,but less strongly at the naupliar stage.Nauplii did not undergo metamorphosis and died at late naupliar stages feeding on A.anophagefferens alone,similar to those under starvation.Furthermore,the presence of A.anophagefferens greatly reduced the reproduction rate of females in mixtures but did not influence the growth rate of copepodids.These results suggest that P.poplesia nauplii may exert grazing pressure on A.anophagefferens population during a brown tide,which,however,may not be persistent because of copepod population decline. | HE Xuejia HAN Didi HAN Liuyu LU Songhui | 2018 | Acta Oceanologica Sinica2018，37，4： | 1 |

| 12 | Allelopathic Interactions Between the Tropical Macrophyte Enhalus acoroides and Epibenthic HAB Dinoflagellate Prorocentrum concavum显示文摘A benthic harmful dinoflagellate bloom caused by Prorocentrum concavum occurred at Xincun Bay,a lagoon characterized by a tropical seagrass ecosystem in the southern China,in summer 2018.Both abiotic and biotic factors may affect the abundance dynamics of P.concavum.One of the biotic factors,allelopathy,is known to be especially common among aquatic species and is suggested to be an economical and environmentally-friendly way to eliminate Benthic Harmful Algal Blooms(BHABs).To investigate the possible allelopathic interactions between seagrasses and P.concavum,a field survey was conducted to study the cell densities of P.concavum on four major substrates over 12 months.In laboratory,fresh Enhalus acoroides leaves and a crude aqueous extract of dry E.acoroides leaves were added to the culture of P.concavum respectively to assess possible effects on the growth and photosynthesis activities of P.concavum cells.Our results showed that the average abundance of P.concavum on E.acoroides leaves was statistically lower than that on the sediment outside the seagrass meadow and that on Thalassia hemperichii leaves.Both the growth and photosynthesis activities of P.concavum cells were inhibited in the two experiments,which can be attributed to the release and production of allelochemicals by E.acoroides.Our results offer new insights into the interaction between the submerged seagrass E.acoroides and the benthic harmful algal bloom dinoflagellate P.concavum,which can influence the abundance dynamics of P.concavum and provide an alternative for reducing potential threat of BHABs. | LIU Hui ZOU Jian XIE Hang ZHENG Chengzhi LU Songhui | 2022 | Journal of Ocean University of China2022，21，6： | 1 |

| 15 | Characterization of the Complete Mitochondrial Genome of Arius dispar(Siluriformes: Ariidae) and Phylogenetic Analysis Among Sea Catfishes显示文摘The mitochondrial genome(mitogenome) was 16792 bp in length, containing 13 protein coding genes(PCGs), two rRNA genes(12 S rRNA and 16 S rRNA), 22 tRNA genes, and two main non-coding regions. Among these 37 genes, 28 genes were encoded on the heavy strand, while 9 genes were transcribed on the light strand. The non-coding regions of A. dispar included a control region, a light strand replication and another 11 intergenic spacers. The CR of A. dispar contained 8 conserved sequence blocks(CSBs), a termination-associated sequence(TAS) and a pyrimidine tract. Phylogenetic analysis based on 12 PCGs revealed that A. dispar was genetically closest to Arius arius. The families Schilbeidae, Claroteidae, Mochokidae, and Ariidae formed a closely evolved clade. Molecular information from this research introduces mitogenomice data of A. dispar and suggests the phylogenetic relationships among Siluriformes. | CUI Lei DONG Yuelei CAO Rongbo ZHOU Xiaoyu LU Songhui | 2020 | Journal of Ocean University of China2020，19，5： | 0 |
| 16 | Distribution and germination of viable diatom resting stage cells in sediments of the East China Sea显示文摘The abundance and temporal patterns of viable diatom resting stage cells in sediments of the East China Sea in 2006 have been investigated.The abundance of viable resting stages was enumerated with the most probable number(MPN) technique.Overall,25 diatom species(including varieties) belonging to 16 genera were detected.Viable resting stage cells were common,on the order of 103 to 106 cells/g dry mass.The abundant taxa included Skeletonema marina,S.dohrnii,Chaetoceros curvisetus and Thalassiosira spp.,with Skeletonema accounting for 83.3% of the cell.The effects of temperature(10,15,20,25 C),salinity(20,25,30,35 psu) and light intensity(0,300,4 000,8 000 lux) on the germination of resting stages in sediment samples were also determined.The results showed that light intensity had a significant positive effect on the germination of diatom resting stage cells(p <0.01) and that diatoms could not germinate in darkness.Temperature and salinity had no noticeable effects on the germination.The present study suggests that there are abundant diatom resting cells in sediments of the East China Sea,which could serve as a 'seed bank' in the phytoplankton population succession and contribute to the initiation of algal blooms. | ZHANG Yuyu LU Songhui ZHANG Chuansong GAO Yahui | 2010 | Acta Oceanologica Sinica2010，29，5： | 0 |
| 17 | Identification of a 10-pseudogenes signature as a novel prognosis biomarker for ovarian cancer显示文摘The outcomes of ovarian cancer are complicated and usually unfavorable due to their diagnoses at a late stage.Identifying the efficient prognostic biomarkers to improve the survival of ovarian cancer is urgently warranted.The survival-related pseudogenes retrieved from the Cancer Genome Atlas database were screened by univariate Cox regression analysis and further assessed by least absolute shrinkage and selection operator(LASSO)method.A risk score model based on the prognostic pseudogenes was also constructed.The pseudogene-mRNA regulatory networks were established using correlation analysis,and their potent roles in the ovarian cancer progression were uncovered by functional enrichment analysis.Lastly,ssGSEA and ESTIMATE algorithms was used to evaluate the levels of immune cell infiltrations in cancer tissues and explore their relationship with risk signature.A prediction model of 10-pseudogenes including RPL10P6,AC026688.1,FAR2P4,AL391840.2,AC068647.2,FAM35BP,GBP1P1,ARL4AP5,RPS3AP2,and AMD1P1 was established.The 10-pseudogenes signature was demonstrated to be an independent prognostic factor in patient with ovarian cancer in the random set(hazard ratio[HR]=2.512,95%confidence interval[CI]=2.03–3.11,P<0.001)and total set(HR=1.71,95%CI=1.472–1.988,P<0.001).When models integrating with age,grade,stage,and risk signature,the Area Under Curve(AUC)of the 1-year,3-year,5-year and 10-year Receiver Operating Characteristic curve in the random set and total set were 0.854,0.824,0.855,0.805 and 0.679,0.697,0.739,0.790,respectively.The results of functional enrichment analysis indicated that the underlying mechanisms by which these pseudogenes influence cancer prognosis may involve the immune-related biological processes and signaling pathways.Correlation analysis showed that risk signature was significantly correlated with immune cell infiltration and immune score.We identified a novel 10-pseudogenes signature to predict the survival of patients with ovarian cancer,and that may serve as novel possible prognostic biomarkers and therapeutic targets for ovarian cancer. | YONGHUI YU SONGHUI XU ERYONG ZHAO YONGSHUN DONG JINBIN CHEN BOQI RAO JIE ZENG LEI YANG JIACHUN LU FUMAN QIU | 2022 | BIOCELL2022，46，4： | 0 |
