| 1 | The Combined Effect of Plastic Particles Size and Concentration on Rotifers’ (Brachionus plicatilis) Performance显示文摘The presence of microplastics in aquatic ecosystems is of increasing global concern.Nano-sized plastics,in particular,can penetrate the cell membrane and cause biological death.Our study evaluated the combined impacts of several polystyrene mi-crospheres’sizes and nominal concentrations on the overall performance changes of Brachionus plicatilis.Experimental animals were exposed to three microplastic sizes(0.08,0.5 and 6μm)and five nominal concentrations(0,0.5,2,8,32μg mL−1)for 20 d.Our results showed that the toxicological effect of particle size on rotifers did not significantly depend on the nominal concentration.The interaction between the nominal concentration and size occurred only for body length and lorica width.Specifically,high nominal concentrations of microplastics that were close to nanometer size significantly impaired the overall vitality of rotifers,embodied in shortage of body type,delay in the arrival of maturity,reduction in the cumulative number of neonates,and the advance of the death process.In comparison,fair-sized size(0.5 and 6μm)displayed non-significant damage except for individual groups.Most notably,the net reproductive yield was only a third of what it was in the original environment,implying that there was not much fertility left.Besides,with the development of rotifers,the adverse effects of polystyrene microsphere drive had become more and more serious. | SUI Yanming WANG Senyang MOHSEN Mohamed ZHANG Longsheng SHEN Mengyan LIU Zhiquan NGUYEN Haidang ZHANG Shengmao LI Kaixing LV Linlan DONG Xuexing | 2022 | Journal of Ocean University of China2022，21，2： | 3 |
| 2 | Multidimensional Information Encryption and Storage:When the Input Is Light显示文摘The issue of information security is closely related to every aspect of daily life.For pursuing a higher level of security,much effort has been continuously invested in the development of information security technologies based on encryption and storage.Current approaches using single-dimension information can be easily cracked and imitated due to the lack of sufficient security.Multidimensional information encryption and storage are an effective way to increase the security level and can protect it from counterfeiting and illegal decryption.Since light has rich dimensions(wavelength,duration,phase,polarization,depth,and power)and synergy between different dimensions,light as the input is one of the promising candidates for improving the level of information security.In this review,based on six different dimensional features of the input light,we mainly summarize the implementation methods of multidimensional information encryption and storage including material preparation and response mechanisms.In addition,the challenges and future prospects of these information security systems are discussed. | Senyang Liu Xiaohu Liu Jinying Yuan Jie Bao | 2021 | Research2021，，1： | 2 |
| 3 | Ancient water wells reveal a prolonged drought in the lower Yellow River area about 2800 years ago显示文摘Proxy records from the North Atlantic realm reveal that large and rapid cooling known as the Bond events continued into the Holocene [1],repeatedly punctuating what is conventionally thought to have been a relatively stable climate.Given that the Holocene is the most recent interglacial period that has spurred the development of modern societies,scrutinizing climate variabil- ity during this period is important not only for predicting the trend of future climate changes,but also for better understanding the driving forces behind the rise and fall of ancient civilizations. | Shiyong Yu Xuexiang Chen Xiuling Liu Zhen Fang Junfeng Guo Senyang Zhan Hui Fang Fahu Chen | 2018 | Science Bulletin2018，63，20： | 1 |

| 9 | A case of polymyositis with ophthalmoplegia Laboratory examinations显示文摘OBJECTIVE: Polymyositis (PM) mainly involves proximal limb and trunk muscles. Ocular muscles are not affected, except in rare cases with both PM and myasthenia gravis (MG). Thus, the results of laboratory examinations in such a patient deserve to be reported. METHODS: To analyze the clinical, imaging and pathology datas on a 65-year-old woman patient with PM with complex symptoms, who presented mainly ophthalmoplegia. The patient consented to all examinations and the hospital Ethics Committee approved the study. The laboratory examinations included creatine kinase (CK), ENA, tumor marker, function of thyroid, cranial MRI, and electromyogram (EMG). Biopsy of the left quadriceps femoris was performed, frozen specimens were stained with hematoxylin and eosin, ATPase, NADH tetrazolium reductase, periodic acid Schiff, oil red O, modified Gomory trichrome and MHC-I, to investigate the pathology of muscle fibers RESULTS: Laboratory results showed: CK, 108.32μkat/L; antinuclear antibody: (+); ENA, (–); tumor marker, (–); normal thyroid function, MRI showed no abnormal signals in brain and extraocular muscles. Electromyography of the bilateral deltoid, biceps brachii, musculus quadriceps fexoris, anterior tibialis showed fibrillation potentials, positive potentials and short-duration, small-amplitude polyphasic potentials on voluntary movements with a full interference pattern on mild exertion. Repetitive stimulation did not result in any increment or decrement in these potentials. A muscle biopsy of the left quadriceps femoris showed many small round muscle fibers without peripheral bundle distribution and apparent myofiber degeneration, necrosis and phagocytosis. There were several focal lymphocyte infiltrations. MHC-I immunohistochemical staining was positive in most fibers revealing inflammatory infiltration of normal fibers with MHC-I expression. CONCLUSION: This patient showed increased CK, typical triad of myopathy in EMG, and apparent degeneration and necrosis in biopsy of quadriceps femoris. Therefore, the diagnosis of PM and involvement of extraocular muscles were definite. | Shunchang Han Chuanqiang Pu Xusheng Huang Senyang Lang Weiping Wu | 2008 | Neural Regeneration Research2008，3，3： | 0 |

| 12 | Rapid Directional Solidification with Ultra-High Temperature Gradient and Cellular Spacing Selection of Cu-Mn Alloy显示文摘The detailed laser surface remelting experiments of Cu-31.4 wt pct Mn and Cu-26.6 wt pct Mn alloys on a 5 kW CO2laser were carried out to study the effects of processing parameters (scanning velocity, output power of laser) on the growthdirection of microstructure in the molten pool and cellular spacing selection under the condition of ultra-high temperaturegradient and rapid directional solidification. The experimental results show that the growth direction of microstructure isstrongly affected by laser processing parameters. The ultra-high temperature gradient directional solidification can be realizedon the surface of samples during laser surface remelting by controlling laser processing parameters, the temperature gradientand growth velocity can reach 106 K/m and 24.1 mm/s, respectively, and the solidification microstructure in the center ofthe molten pool grows along the laser beam scanning direction. There exists a distribution range of cellular spacings underthe laser rapid solidification conditions, and the average spacing decreases with increasing of growth rate. The maximum,λ minimum, λmin, and average primary spacing,λ, as functions of growth rate, Vb, can be given by, λ =12.54V b-0.61,λmin=4.47 Vb-0.52, λ=9.09Vb-0.62, respectively. The experimental results are compared with the current Hunt-Lu model forrapid cellular/dendritic growth, and a good agreement is found. | SenYANG YunpengSU WenjinLIU WeidongHUANG YaoheZHOU | 2003 | Journal of Materials Science & Technology2003，19，3： | 0 |
| 13 | Facile hydrothermal construction of Nb2CTx/Nb2O5 as a hybrid anode material for high-performance Li-ion batteries显示文摘Herein,a simple yet efficient hydrothermal strategy is developed to in-situ convert multi-layered niobium-based MXene(Nb2 CTx)to hierarchical Nb2 CTx/Nb2O5 composite.In the hybrid,the Nb2O5 nanorods are well dispersed in and/or on the Nb2 CTx.Thanks to the synergetic contributions from the high capacity of Nb2O5 and superb electrical conductivity of the two-dimensional Nb2 CTx itself,the resultant Nb2 CTx/Nb2O5 hybrid exhibits excellent rate behaviors and stable long-term cycling behaviors,when evaluated as anodes for Li-ion batteries. | Li Qin Senyang Xu Yang Liu Shuhao Zhu Linrui Hou Changzhou Yuan | 2020 | Chinese Chemical Letters2020，31，4： | 0 |
| 14 | Clinical manifestation, imageological and pathological characteristics of Wernicke encephalopathy显示文摘BACKGROUND: The clinical manifestations of Wernicke encephalopathy(WE) are atypical and short of effective auxiliary examination means. The effects of magnetic resonance imaging (MRI) in the diagnosis of WE have been reported successively. But its imageological detection needs to be further investigated. OBJECTIVE: To analyze the characteristics of clinical manifestations, skull MRI examination and pathological results in patients with WE. DESIGN: Retrospective analysis. SETTING: The General Hospital of Chinese PLA. PARTICIPANTS: Ten patients of WE admitted to the Department of Neurology, General Hospital of Chinese PLA were recruited. Among them, five patients were diagnosed pathologically after death. Their pathological changes accorded with the pathological characteristics of WE. The other 5 patients were diagnosed clinically before death. Their pathological changes accorded with clinical and imageological manifestations and had definite reaction to the treatment of thiamine. Ten patients, 7 males and 3 females, were aged (47±13) years ranging from 33 to 73 years. Their disease courses averaged 6 weeks ranging from 3 to 10 weeks. They all were non-alcoholics. Four patients developed WE after acute pancreatitis, two patients after the recurrence of gastric cancer, two patients after cholecystectomy, one patient after hepatitis medicamentosa, one patient after Alzheimer disease. Informed consents were obtained from all the patients and their relatives. METHODS: After admission, clinical manifestations of patients were observed and recorded. Five patients underwent skull MRI examination and their detected results were recorded. Five dead patients underwent autopsy and brain pathological examinations. Neuropathological examination involved cerebrum, cerebellum and brain stem. MAIN OUTCOME MEASURES: Clinical manifestations, MRI examination results, pathological analysis results and prognosis of all the patients. RESULTS: Ten patients with WE were involved in the final analysis. ①Nine patients presented various degrees of mental and conscious disturbance. Six patients initially presented vertigo, nausea, and vomiting. Five patients showed opthalmoplegia. Three patients presented hypotension (BP < 120/60 mm Hg, 1 mm Hg= 0.133 kPa). Two patients showed ataxia. One patient showed severe polyneuropathy. Both lower extremities were more severe. EMG showed axonal degeneration. ②Five patients accepted skull MRI examination. Three patients showed typical high signals in periaqueductal regions and circumference of third and fourth ventriculus in T2 -weighted and flair-weighted images, two of them showed high signals in fornixes in T2 -weighted and flair-weighted images, and one of them showed high signals in optic chiasma, both mammillary bodies, and subcortical white matter. No abnormality was found in the other two patients. Two patients who accepted the supplements of thiamine showed obviously improvements in the second MRI examination. ③Macroscopically, the border between gray and white matters was clear in the coronal section of cerebrum. Congestions, edema and multiple petechial hemorrhages were found in periaqueductal regions, circumference of third and fourth ventriculus, and both mammillary bodies. Microscopically, various degrees of necrosis of parenchymal structures, loss of nerve cells and ischemic changes were found. Myelinated fibers were more affected than neurons. There were focal capillary proliferation and multiple petechial hemorrhages. Prominent astrocytic proliferations were found in gelatinous fiber staining. And demyelinations were found in myelin staining. These pathological findings were all in accord with the diagnostic criteria of WE. ④In the diagnosis before death, 4 of 5 patients who were supplemented with thiamine had obvious improvement 2 weeks later and 1 of them abandoned therapy due to progressive aggravation of jaundice caused by recurrence of stomach cancer. The other 5 patients who were not diagnosed definitely before death and not supplemented with thiamine died. Final diagnosis was performed in autopsy examination. CONCLUSION: The clinical manifestations of this group of WE patients are atypical. MRI and pathological examination results are corresponding, and both have the characteristic manifestations of WE. | Shunchang Han 1,2, Chuanqiang Pu2, Qiuping Gui3, Xusheng Huang2, Senyang Lang2, Weiping Wu2, Peifu Wang2 1Department of Neurology, Second Hospital Affiliated to China Medical University, Shenyang 110003, Liaoning Province, China 2Department of Neurology, 3Department of Pathology, General Hospital of Chinese PLA, Beijing 100853, China | 2006 | Neural Regeneration Research2006，1，8： | 0 |
| 15 | Modeling of hydrogen diffusion process at a blunt notch in zirconium显示文摘The two-dimensional diffusion of interstitial hydrogen atoms in zirconium in a non-uniform stress field was simulated us- ing the phase-field method. The interaction between hydrogen interstitials and the stress field was described by Khachaturyan’s elastic theory. The Cahn-Hilliard diffusion equation was then solved by an explicit finite difference method. The result shows that hydrogen atoms diffuse to the high-tensile hydrostatic region near the tip of the notch. The content of hydrogen near the tip of the notch increases by 13%, while the stress distribution caused by hydrogen interstitials around the notch is modified by only 0.7%. | Xingqiao Ma Sanqiang Shi Senyang Hu Chungho Woo Longqing Chen | 2005 | Journal of University of Science and Technology Beijing2005，12，5： | 0 |
| 16 | Effect of swimming training on neural microcirculation in rats with sciatic nerve compression A study based on laser Doppler flowmetry显示文摘Microcirculation of the peripheral nerve is necessary for neural growth and regeneration.However,technical limitations have limited studies in this area.The few studies conducted have concerned active exercise effects on microcirculation of the peripheral nerve.Using an animal experiment,this study evaluated the effect of swimming training on microcirculation of injured peripheral nerve by laser Doppler flowmetry.The results showed that the blood vessel at the distal end of the peripheral nerve was the main blood supply for the nerve,and the internal blood supply for the nerve had strong compensatory ability.Swimming training promoted the functional recovery of rats with sciatic nerve injury and the regeneration of myelin sheath and blood vessels,but had no impact on neural blood flow. | Yueming Gao Xinglin Wang Senyang Lang Lining Zhang Wei Suo Tianyu Jiang Jingping Fan | 2010 | Neural Regeneration Research2010，5，19： | 0 |
