| 1 | Effects of different resuscitation fluid on severe acute pancreatitis显示文摘AIM: To compare effects of different resuscitation fluid on microcirculation, inflammation, intestinal barrier and clinical results in severe acute pancreatitis (SAP). METHODS: One hundred and twenty patients with SAP were enrolled at the Pancreatic Disease Institute between January 2007 and March 2010. The patients were randomly treated with normal saline (NS group), combination of normal saline and hydroxyethyl starch (HES) (SH group), combination of normal saline, hydroxyethyl starch and glutamine (SHG group) in resuscitation. The ratio of normal saline to HES in the SH and SHG groups was 3:1. The glutamine (20% glutamine dipeptide, 100 mL/d) was supplemented into the resuscitation liquid in the SHG group. Complications and outcomes including respiratory and abdominal infection, sepsis, abdominal hemorrhage, intra-abdominal hypertension, abdominal compartment syndrome (ACS), renal failure, acute respiratory distress syndrome (ARDS), multiple organ dysfunction syndrome (MODS), operation intervention, length of intensive care unit stay, length of hospital stay, and mortality at 60 d were compared. Moreover, blood oxygen saturation (SpO 2 ), gastric intramucosal pH value (pHi), intra-abdominal pressure (IAP), inflammation cytokines, urine lactulose/mannitol (L/M) ratio, and serum endotoxin were investigated to evaluate the inflammatory reaction and gut barrier. RESULTS: Compared to the NS group, patients in the SH and SHG groups accessed the endpoint more quickly (3.9 ± 0.23 d and 4.1 ± 0.21 d vs 5.8 ± 0.25 d, P < 0.05) with less fluid volume (67.26 ± 28.53 mL/kg/d, 61.79 ± 27.61 mL/kg per day vs 85.23 ± 21.27 mL/kg per day, P < 0.05). Compared to the NS group, incidence of renal dysfunction, ARDS, MODS and ACS in the SH and SHG groups was obviously lower. Furthermore, incidence of respiratory and abdominal infection was significantly decreased in the SH and SHG groups, while no significant difference in sepsis was seen. Moreover, less operation time was needed in the SH and SHG group than the NS group, but the difference was not significant. The mortality did not differ significantly among these groups. Blood SpO 2 and gastric mucosal pHi in the SH and SHG groups increased more quickly than in the NS group, while IAP was significantly decreased in the SH and SHG group. Moreover, the serum tumor necrosis factor-α, interleukin-8 and C-reactive protein levels in the SH and SHG groups were obviously lower than in the NS group at each time point. Furthermore, urine L/M ratio and serum endotoxin were significantly lower in the SH group and further decreased in the SHG group.CONCLUSION: Results indicated that combination of normal saline, HES and glutamine are more efficient in resuscitation of SAP by relieving inflammation and sustaining the intestinal barrier. | Gang Zhao Jun-Gang Zhang He-Shui Wu Jin Tao Qi Qin Shi-Chang Deng Yang Liu Lin Liu Bo Wang Kui Tian Xiang Li Shuai Zhu Chun-You Wang | 2013 | World Journal of Gastroenterology2013，19，13： | 56 |
| 2 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 3 | How many sutures in the southern Central Asian Orogenic Belt:Insights from East Xinjiang-West Gansu(NW China)?显示文摘How ophiolitic mèlanges can be defined as sutures is controversial with regard to accretionary orogenesis and continental growth.The Chinese Altay,East junggar,Tianshan,and Beishan belts of the southern Central Asian Orogenic Belt(CAOB) in Northwest China,offer a special natural laboratory to resolve this puzzle.In the Chinese Altay,the Erqis unit consists of ophiolitic melanges and coherent assemblages,forming a Paleozoic accretionary complex.At least two ophiolitic melanges(Armantai,and Kelameili) in East Junggar,characterized by imbricated ophiolitic melanges,Nb-enriched basalts,adakitic rocks and volcanic rocks,belong to a Devonian-Carboniferous intra-oceanic island arc with some Paleozoic ophiolites,superimposed by Permian arc volcanism.In the Tianshan,ophiolitic melanges like Kanggurtag,North Tianshan,and South Tianshan occur as part of some Paleozoic accretionary complexes related to amalgamation of arc terranes.In the Beishan there are also several ophiolitic melanges,including the Hongshishan,Xingxingxia-Shibangjing,Hongliuhe-Xichangjing,and Liuyuan ophiolitic units.Most ophiolitic melanges in the study area are characterized by ultramafic,mafic and other components,which are juxtaposed,or even emplaced as lenses and knockers in a matrix of some coherent units.The tectonic settings of various components are different,and some adjacent units in the same melange show contrasting different tectonic settings.The formation ages of these various components are in a wide spectrum,varying from Neoproterozoic to Permian.Therefore we cannot assume that these ophiolitic melanges always form in linear sutures as a result of the closure of specific oceans.Often the ophiolitic components formed either as the substrate of intra-oceanic arcs,or were accreted as lenses or knockers in subduction-accretion complexes.Using published age and paleogeographic constraints,we propose the presence of (1) a major early Paleozoic tectonic boundary that separates the Chinese Altay-East Junggar multiple subduction systems of the southern Siberian active margin from those of the northern Tarim;and (2) a major Permian suture zone that separates the Tianshan-Beishan from the northern active margin of the Tarim Craton.These new observations and interpretations have broad implications for the architecture and crustal growth of central Asia and other ancient orogens as well. | Wenjiao Xiao Chunming Han Wei Liu Bo Wan Ji'en Zhang Songjian Ao Zhiyong Zhang Dongfang Song Zhonghua Tian Jun Luo | 2014 | Geoscience Frontiers2014，5，4： | 31 |
| 4 | Long-term follow-up of the effects of fecal microbiota transplantation in combination with soluble dietary fiber as a therapeutic regimen in slow transit constipation显示文摘As some studies have reported that strategies targeting the gut microbiota such as fecal microbiota transplantation(FMT) with or without other microecological therapy might have efficacy in treating slow transit constipation(STC), we conducted a singlecenter, open-label trial to study the long-term effect of FMT combined with soluble dietary fiber(pectin) on STC. Thirty-one adult patients with STC were enrolled into the trial. Patients received 6-day FMT procedures repeatedly for the first 3 months and soluble dietary fiber(pectin) daily during the follow-up. The rate of clinical remission and improvement, stool consistency, the Wexner constipation scale, and assessment of constipation-related symptoms were evaluated at week 4 and 1 year later. The clinical remission and improvement rates at week 4 were 69.0%(20/29) and 75.9%(22/29), respectively. At the end of the study,48.3%(14/29) of patients continued to have at least three complete spontaneous bowel movements per week and 58.6%(17/29)of patients showed clinical improvements. Stool consistency, the Wexner constipation scale, and constipation symptoms improved both at short-term and long-term follow-up. The results indicated that FMT in combination with soluble dietary fiber(pectin) had both short-term and long-term efficacy in treating STC. | Xueying Zhang Hongliang Tian Lili Gu Yongzhan Nie Chao Ding Xiaolong Ge Bo Yang Jianfeng Gong Ning Li | 2018 | Science China(Life Sciences)2018，61，7： | 33 |
| 5 | Intracoronary arterial retrograde thrombolysis with percutaneous coronary intervention: a novel use of thrombolytic to treat acute ST-segment elevation myocardial infarction显示文摘Background Clearance of coronary arterial thrombosis is necessary in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). There is currently no highly-recommended method of thrombus removal during interventional procedures. We describe a new method for opening culprit vessels to treat STEMI: intracoronary arterial retrograde thrombolysis (ICART) with PCI. Methods & Results Eight patients underwent ICART. The guidewire was advanced to the distal coronary artery through the occlusion lesion. Then, we inserted a microcatheter into the distal end of the occluded coronary artery over the guidewire. Urokinase (5–10 wu) mixed with contrast agents was slowly injected into the occluded section of the coronary artery through the microcatheter. The intracoronary thrombus gradually dissolved in 3–17 min, and the effect of thrombolysis was visible in real time. Stents were then implanted according to the characteristics of the recanalized culprit lesion to achieve full revascularization. One patient experienced premature ventricular contraction during vascular revascularization, and no malignant arrhythmias were seen in any patient. No reflow or slow flow was not observed post PCI. Thrombolysis in myocardial infarction flow grade and myocardial blush grade post-primary PCI was 3 in all eight patients. No patients experienced bleeding or stroke. Conclusions ICART was accurate and effective for treating intracoronary thrombi in patients with STEMI in this preliminary study. ICART was an effective, feasible, and simple approach to the management of STEMI, and no intraprocedural complications occurred in any of the patients. ICART may be a breakthrough in the treatment of acute STEMI. | Jin-Wen TIAN Mei ZHU Feng-Qi WANG Ke LI Chao-Fei ZHOU Bo LI Min WANG Jue-Lin DENG Bo JIANG Jing BAI Yi GUO Rong-Jie JIN Zhao ZHANG Ying LIN Ji-Hang WANG Shi-Hao ZHAO Ming-Zhi SHEN | 2019 | Journal of Geriatric Cardiology2019，16，6： | 22 |

| 9 | Identification Standard for ENSO Events and Its Application to Climate Monitoring and Prediction in China显示文摘The El Ni?o–Southern Oscillation(ENSO)reflects anomalous variations in the sea surface temperature(SST)and atmospheric circulation over the tropical central–eastern Pacific.It remarkably impacts on weather and climate worldwide,so monitoring and prediction of ENSO draw intensive research.However,there is not yet a unique standard internationally for identifying the timing,intensity,and type of ENSO events.The National Climate Center of China Meteorological Administration(NCC/CMA)has led the effort to establish a national identification standard of ENSO events,which was officially endorsed by the National Standardization Administration of China and implemented operationally in NCC/CMA in 2017.In this paper,two key aspects of this standard are introduced.First,the Ni?o3.4 SST anomaly index,which is well-recognized in the international ENSO research community and used operationally in the US,has replaced the previous Ni?o Z index and been used to identify the start,end,and peak times,and intensity of ENSO events.Second,two new indices—the eastern Pacific ENSO(EP)index and the central Pacific ENSO(CP)index,based on the SST conditions in Ni?o3 and Ni?o4 region respectively,are calculated to first determine the ENSO type before monitoring and assessing the impacts of ENSO on China’s climate.With this standard,all historical ENSO events since 1950 are consistently re-identified;their distinct properties are diagnosed and presented;and the impacts of ENSO events under different types on China’s climate are re-assessed.This standard is also employed to validate the intensity,grade,and type of the ENSO events predicted by the NCC/CMA operational ENSO prediction system.The new standard and the thus derived unified set of re-analyzed historical ENSO events and associated information provide a good reference for better monitoring and prediction of future ENSO events. | Hong-Li REN Bo LU Jianghua WAN Ben TIAN Peiqun ZHANG | 2018 | Journal of Meteorological Research2018，32，6： | 16 |
| 10 | Study of atmospheric CO2 and CH4 at Longfengshan WMO/GAW regional station: The variations, trends, influence of local sources/sinks, and transport显示文摘Atmospheric CO_2 and CH_4 have been continuously measured since 2009 at Longfengshan WMO/GAW station(LFS) in China. Variations of the mole fractions, influence of long-distance transport, effects of local sources/sinks and the characteristics of synoptic scale variations have been studied based on the records from 2009 to 2013. Both the CO_2 and CH_4 mole fractions display increasing trends in the last five years, with growth rates of 3.1±0.02 ppm yr.1 for CO_2 and 8±0.04 ppb yr.1(standard error, 1-σ)for CH_4. In summer, the regional CO_2 mole fractions are apparently lower than the Marine Boundary Layer reference, with the lowest value of.13.6±0.7 ppm in July, while the CH_4 values are higher than the MBL reference, with the maximum of 139±6 ppb.From 9 to 17(Local time, LT) in summer, the atmospheric CO_2 mole fractions at 10 m a.g.l. are always lower than at 80 m, with a mean difference of.1.1±0.2 ppm, indicating that the flask sampling approach deployed may underestimate the background mole fractions in summer. In winter, anthropogenic emissions dominate the regional CO_2 and CH_4 mole fractions. Cluster analysis of backward trajectories shows that atmospheric CO_2 and CH_4 at LFS are influenced by anthropogenic emissions from the southwest(Changchun and Jilin city) all year. The synoptic scale variations indicate that the northeastern China plain acts as an important source of atmospheric CO_2 and CH_4 in winter. | FANG ShuangXi Pieter P.TANS YAO Bo LUAN Tian WU YanLing YU DaJiang | 2017 | Science China Earth Sciences2017，60，10： | 16 |

| 12 | Antioxidant and Anti-inflammatory Capacity of Ferulic Acid Released from Wheat Bran by Solid-state Fermentation of Aspergillus niger显示文摘Objective A strain of Aspergillus niger(A. niger), capable of releasing bound phenolic acids from wheat bran, was isolated. This strain was identified by gene sequence identification. The antioxidant and anti-inflammatory capacity of ferulic acid released from wheat bran by this A. niger strain(FA-WB) were evaluated. Methods Molecular identification techniques based on PCR analysis of specific genomic sequences were conducted; antioxidant ability was examined using oxygen radical absorbance capacity(ORAC), cellular antioxidant activity(CAA) assays, and erythrocyte hemolysis assays. RAW264.7 cells were used as a model to detect anti-inflammatory activity. Results The filamentous fungal isolate was identified to be A. niger. ORAC and CAA assay showed that FA-WB had better antioxidant activity than that of the ferulic acid standard. The erythrocyte hemolysis assay results suggested that FA-WB could attenuate AAPH-induced oxidative stress through inhibition of reactive oxy gen species(ROS) generation. FA-WB could significantly restore the AAPH-induced increase in intracellular antioxidant enzyme activities to normal levels as well as inhibit the intracellular malondialdehyde formation. TNF-?, IL-6, and NO levels indicated that FA-WB can inhibit the inflammation induced by lipopolysaccharide(LPS). Conclusion Ferulic acid released from wheat bran by a new strain of A. niger had good anti-inflammatory activity and better antioxidant ability than standard ferulic acid. | YIN Zhi Na WU Wen Jia SUN Chong Zhen LIU Hui Fan CHEN Wen Bo ZHAN Qi Ping LEI Zhuo Gui XIN Xuan MA Juan Juan YAO Kun MIN Tian ZHANG Meng Meng WU Hui | 2019 | Biomedical and Environmental Sciences2019，32，1： | 14 |
| 13 | NUMERICAL SIMULATION OF FLOW AND HEAT TRANSFER CHARA-CTERISTICS OUTSIDE A PERIODICALLY VIBRATING TUBE显示文摘Fluid flow and heat transfer characteristics outside a vibrating tube were numerically simulated by the dynamic mesh method. The mechanism of heat transfer enhancement via periodic vibration of the tube was explored by using the field synergy principle. It is found that the field synergy angle between fluid velocity vector and temperature gradient vector for a periodically vibrating tube is significantly smaller than that for a stationary tube, and it changes approximately according to the sinusoidal law in a vibration period. The effect of time phase of the vibration on the field synergy angle and convective heat transfer coefficient were also discussed. Results indicate that the vibration can enhance heat transfer and this effect is more remarkable when time phase angle ranges between 50o and 140o in a half period. Especially when the time phase angle is 90o, the average field synergy angle outside the tube reaches the minimum, which leads to the best heat transfer performance. | JIANG Bo TIAN Mao-cheng LENG Xue-li TANG Yu-feng PAN Ji-hong | 2008 | Journal of Hydrodynamics2008，20，5： | 14 |
| 14 | Prediction of Primary Climate Variability Modes at the Beijing Climate Center显示文摘Climate variability modes, usually known as primary climate phenomena, are well recognized as the most important predictability sources in subseasonal–interannual climate prediction. This paper begins by reviewing the research and development carried out, and the recent progress made, at the Beijing Climate Center(BCC) in predicting some primary climate variability modes. These include the El Ni?o–Southern Oscillation(ENSO), Madden–Julian Oscillation(MJO), and Arctic Oscillation(AO), on global scales, as well as the sea surface temperature(SST) modes in the Indian Ocean and North Atlantic, western Pacific subtropical high(WPSH), and the East Asian winter and summer monsoons(EAWM and EASM, respectively), on regional scales. Based on its latest climate and statistical models, the BCC has established a climate phenomenon prediction system(CPPS) and completed a hindcast experiment for the period 1991–2014. The performance of the CPPS in predicting such climate variability modes is systematically evaluated. The results show that skillful predictions have been made for ENSO, MJO, the Indian Ocean basin mode, the WPSH, and partly for the EASM, whereas less skillful predictions were made for the Indian Ocean Dipole(IOD) and North Atlantic SST Tripole, and no clear skill at all for the AO, subtropical IOD, and EAWM. Improvements in the prediction of these climate variability modes with low skill need to be achieved by improving the BCC's climate models, developing physically based statistical models as well as correction methods for model predictions.Some of the monitoring/prediction products of the BCC-CPPS are also introduced in this paper. | Hong-Li REN Fei-Fei JIN Lianchun SONG Bo LU Ben TIAN Jinqing ZUO Ying LIU Jie WU Chongbo ZHAO Yu NIE Peiqun ZHANG Jin BA Yujie WU Jianghua WAN Yuping YAN Fang ZHOU | 2017 | Journal of Meteorological Research2017，31，1： | 13 |
| 15 | Optimum design of hierarchical stiffened shells for low imperfection sensitivity显示文摘A concept of hierarchical stiffened shell is proposed in this study,aiming at reducing the imperfection sensitivity without adding additional weight.Hierarchical stiffened shell is composed of major stiffeners and minor stiffeners,and the minor stiffeners are generally distributed between adjacent major stiffeners.For various types of geometric imperfections,e.g.,eigenmode-shape imperfections,hierarchical stiffened shell shows significantly low imperfection sensitivity compared to traditional stiffened shell.Furthermore,a surrogate-based optimization framework is proposed to search for the hierarchical optimum design.Then,two optimum designs based on two different optimization objectives(including the critical buckling load and the weighted sum of collapse loads of geometrically imperfect shells with small-and large-amplitude imperfections)are compared and discussed in detail.The illustrative example demonstrates the inherent superiority of hierarchical stiffened shells in resisting imperfections and the effectiveness of the proposed framework.Moreover,the decrease of imperfection sensitivity can finally be converted into a decrease of structural weight,which is particularly important in the development of large-diameter launch vehicles. | Bo Wang Peng Hao Gang Li Jia-Xin Zhang Kai-Fan Du Kuo Tian Xiao-Jun Wang Xiao-Han Tang | 2014 | Acta Mechanica Sinica2014，30，3： | 12 |
| 16 | Microstructure and Mechanical Properties of Al_2O_3/ZrO_2 Directionally Solidified Eutectic Ceramic Prepared by Laser 3D Printing显示文摘Directionally solidified eutectic ceramics such as(Al)_2O_3/ZrO_2 are promising structural materials for applications in harsh environment with an ultrahigh temperature. In this work, through adopting assistant heating laser 3D printing,(Al)_2O_3/ZrO_2eutectic samples were manufactured with suppressing the formation of cracks. The dependence of the average rod spacing(λav) on the scanning rate(V) follows a relation with λav V0.5= 1 μm1.5s–0.5. Typical eutectic microstructures, so-called complex regular, were analyzed with respect to its evolution with modulating the growth conditions. Formation mechanism of the solidification defect, shrinkage porosity, was discussed and the defect is found to be significantly suppressed by optimizing the solidification parameters. The maximum hardness and fracture toughness are measured to be 16.7 GPa and 4.5 MPa m1/2, respectively. The interplay between the propagation of cracks and the (Al)_2O_3/ZrO_2 interface is discussed. | Zhi Liu Kan Song Bo Gao Tian Tian Haiou Yang Xin Lin Weidong Huang | 2016 | Journal of Materials Science & Technology2016，32，4： | 12 |

| 18 | Global Dynamic Molecular Profiling of Stomatal Lineage Cell Development by Single-Cell RNA Sequencing显示文摘The regulation of stomatal lineage cell development has been extensively investigated.However,a comprehensive characterization of this biological process based on single-cell transcriptome analysis has not yet been reported.In this study,we performed RNA sequencing on 12844 individual cells from the cotyledons of 5-day-old Arabidopsis seedlings.We identified 11 cell clusters corresponding mostly to cells at specific stomatal developmental stages using a series of marker genes.Comparative analysis of genes with the highest variable expression among these cell clusters revealed transcriptional networks that regulate development from meristemoid mother cells to guard mother cells.Examination of the developmental dynamics of marker genes via pseudo-time analysis revealed potential interactions between these genes.Collectively,our study opens the door for understanding how the identified novel marker genes participate in the regulation of stomatal lineage cell development. | Zhixin Liu Yaping Zhou Jinggong Guo Jiaoai Li Zixia Tian Zhinan Zhu Jiajing Wang Rui Wu Bo Zhang Yongjian Hu Yijing Sun Yan Shangguan Weiqiang Li Tao Li Yunhe Hu Chenxi Guo Jean-David Rochaix Yuchen Miao Xuwu Sun | 2020 | Molecular Plant2020，13，8： | 11 |
| 19 | Ice radar investigation at Dome A, East Antarctica:Ice thickness and subglacial topography显示文摘Dome A, located in the central East Antarctic ice sheet (EAIS), is the highest summit of the Antarctic ice sheet. From ice-sheet evolution modeling results, Dome A is likely to preserve over one million years of the Earth's paleo-climatic and -environmental records, and considered an ideal deep ice core drilling site. Ice thickness and subglacial topography are critical factors for ice-sheet models to determine the timescale and location of a deep ice core. During the 21st and 24th Chinese National Antarctic Research Expedition (CHINARE 21, 2004/05; CHINARE 24, 2007/08), ground-based ice radar systems were used to a three-dimensional investigation in the central 30 km×30 km region at Dome A. The successfully obtained high resolution and accuracy data of ice thickness and subglacial topography were then interpolated into the ice thickness distribution and subglacial topography digital elevation model (DEM) with a regular grid resolution of 140.5 m×140.5 m. The results of the ice radar investigation indicate that the average ice thickness in the Dome A central 30 km×30 km region is 2233 m, with a minimal ice thickness of 1618 m and a maximal ice thickness of 3139 m at Kunlun Station. The subglacial topography is relatively sharp, with an elevation range of 949-2445 m. The typical, clear mountain glaciation morphology is likely to reflect the early evolution of the Antarctic ice sheet. Based on the ice thickness distribution and subglacial topography characteristics, the location of Kunlun Station was suggested to carry out the first high-resolution, long time-scale deep ice core drilling. However, the internal structure and basal environments at Kunlun Station still need further research to determine. | CUI XiangBin SUN Bo TIAN Gang TANG XueYuan ZHANG XiangPei JIANG YunYun GUO JingXue LI Xin | 2010 | Chinese Science Bulletin2010，55，4： | 11 |
| 20 | Enhancement of acellular cartilage matrix scaffold by Wharton’s jelly mesenchymal stem cell-derived exosomes to promote osteochondral regeneration显示文摘Articular cartilage defect repair is a problem that has long plagued clinicians.Although mesenchymal stem cells(MSCs)have the potential to regenerate articular cartilage,they also have many limitations.Recent studies have found that MSC-derived exosomes(MSC-Exos)play an important role in tissue regeneration.The purpose of this study was to verify whether MSC-Exos can enhance the reparative effect of the acellular cartilage extracellular matrix(ACECM)scaffold and to explore the underlying mechanism.The results of in vitro experiments show that human umbilical cord Wharton’s jelly MSC-Exos(hWJMSC-Exos)can promote the migration and proliferation of bone marrow-derived MSCs(BMSCs)and the proliferation of chondrocytes.We also found that hWJMSC-Exos can promote the polarization of macrophages toward the M2 phenotype.The results of a rabbit knee osteochondral defect repair model confirmed that hWJMSC-Exos can enhance the effect of the ACECM scaffold and promote osteochondral regeneration.We demonstrated that hWJMSC-Exos can regulate the microenvironment of the articular cavity using a rat knee joint osteochondral defect model.This effect was mainly manifested in promoting the polarization of macrophages toward the M2 phenotype and inhibiting the inflammatory response,which may be a promoting factor for osteochondral regeneration.In addition,microRNA(miRNA)sequencing confirmed that hWJMSC-Exos contain many miRNAs that can promote the regeneration of hyaline cartilage.We further clarified the role of hWJMSC-Exos in osteochondral regeneration through target gene prediction and pathway enrichment analysis.In summary,this study confirms that hWJMSC-Exos can enhance the effect of the ACECM scaffold and promote osteochondral regeneration. | Shuangpeng Jiang Guangzhao Tian Zhen Yang Xiang Gao Fuxin Wang Juntan Li Zhuang Tian Bo Huang Fu Wei Xinyu Sang Liuqi Shao Jian Zhou Zhenyong Wang Shuyun Liu Xiang Sui Quanyi Guo Weimin Guo Xu Li | 2021 | Bioactive Materials2021，6，9： | 11 |
