1Investigation and assessment on mountain tunnels and geotechnical damage after the Wenchuan earthquake显示文摘On May 12, 2008, a strong earthquake with a magnitude of 8.0 (Ms) struck Wenchuan town, in the eastern Sichuan area of west China. Following the earthquake on May 18, the Southwest Jiaotong University organized a damage survey team and dispatched it to the affected area for the investigation into the damage and collection of information and data. This paper outlines the findings of this investigation on the earthquake disaster to mountain tunnels and geotechnical engineering. The systematic investigation, involving geological conditions, design documents, construction and maintenance records of the tunnels, has been conducted and the degree of damage to investigated tunnels has been assessed according to the width and length of cracks, the stability of the slope above the tunnel, and the condition of the groundwater inrush. The results show that the major damage of the mountain tunnels was mainly concentrated in the tunnel portals due to widespread landslides and rockfalls, and the inner part of investigated tunnels suffered moderate damages mainly due to fault displacements. It is hoped that the information shared herein could enhance the outstanding of seismic behavior of mountain tunnels and improve seismic design and construction procedures.WANG ZhengZheng GAO Bo JIANG YuanJun YUAN Song 2009Science China(Technological Sciences)2009,52,2:84

4Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection.Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu 2020Science China(Life Sciences)2020,63,3:157
5Mesenchymal stem cells derived from human placenta suppress allogeneic umbilical cord blood lymphocyte proliferation显示文摘ABSTRACTHuman placenta-derived mononuclear cells (MNC) were isolated by a Percoll density gradient and cultured in mesen-chymal stem cell (MSC) maintenance medium. The homogenous layer of adherent cells exhibited a typical fibroblast-like morphology, a large expansive potential, and cell cycle characteristics including a subset of quiescent cells. In vitrodifferentiation assays showed the tripotential differentiation capacity of these cells toward adipogenic, osteogenic andchondrogenic lineages. Flow cytometry analyses and immunocytochemistry stain showed that placental MSC was ahomogeneous cell population devoid of hematopoietic cells, which uniformly expressed CD29, CD44, CD73, CD105,CD166, laminin, fibronectin and vimentin while being negative for expression of CD31, CD34, CD45 and α-smoothmuscle actin. Most importantly, immuno-phenotypic analyses demonstrated that these cells expressed class I majorhistocompatibility complex (MHC-I), but they did not express MHC-II molecules. Additionally these cells could sup-press umbilical cord blood (UCB) lymphocytes proliferation induced by cellular or nonspecific mitogenic stimuli. Thisstrongly implies that they may have potential application in allograft transplantation. Since placenta and UCB arehomogeneous, the MSC derived from human placenta can be transplanted combined with hematopoietic stem cells(HSC) from UCB to reduce the potential graft -versus-host disease (GVHD) in recipients.Chang Dong LI Wei Yuan ZHANG He Lian LI Xiao Xia JIANG Yi ZHANG Pei Hsien TANG Ning MAO 2005Cell Research2005,15,7:36

7Anisotropic coding metamaterials and their powerful manipulation of differently polarized terahertz waves显示文摘Metamaterials based on effective media can be used to produce a number of unusual physical properties(for example,negative refraction and invisibility cloaking)because they can be tailored with effective medium parameters that do not occur in nature.Recently,the use of coding metamaterials has been suggested for the control of electromagnetic waves through the design of coding sequences using digital elements‘0’and‘1,'which possess opposite phase responses.Here we propose the concept of an anisotropic coding metamaterial in which the coding behaviors in different directions are dependent on the polarization status of the electromagnetic waves.We experimentally demonstrate an ultrathin and flexible polarization-controlled anisotropic coding metasurface that functions in the terahertz regime using specially designed coding elements.By encoding the elements with elaborately designed coding sequences(both 1-bit and 2-bit sequences),the x-and y-polarized waves can be anomalously reflected or independently diffused in three dimensions.The simulated far-field scattering patterns and near-field distributions are presented to illustrate the dual-functional performance of the encoded metasurface,and the results are consistent with the measured results.We further demonstrate the ability of the anisotropic coding metasurfaces to generate a beam splitter and realize simultaneous anomalous reflections and polarization conversions,thus providing powerful control of differently polarized electromagnetic waves.The proposed method enables versatile beam behaviors under orthogonal polarizations using a single metasurface and has the potential for use in the development of interesting terahertz devices.Shuo Liu Tie Jun Cui Quan Xu Di Bao Liangliang Du Xiang Wan Wen Xuan Tang Chunmei Ouyang Xiao Yang Zhou Hao Yuan Hui Feng Ma Wei Xiang Jiang Jiaguang Han Weili Zhang Qiang Cheng 2016Light(Science & Applications)2016,5,1:36
8Early Paleozoic ridge subduction in the Chinese Altai: Insight from the abrupt change in zircon Hf isotopic compositions显示文摘Zircons were separated from granitoids, gneisses, and sedimentary rocks of the Chinese Altai. Those with igneous characteristics yielded U-Pb ages of 280-2800 Ma, recording a long history of magmatic activity in the region. Zircon Hf isotopic compositions show an abrupt change at ~420 Ma, indicating that prior to that time the magmas came from both ancient and juvenile sources, whereas younger magmas were derived mainly from juvenile material. This may imply that the lithosphere was signifi- cantly modified in composition by a rapid addition of melt from the mantle. We suggest that this dramatic change was due to the onset of ridge subduction, which can account not only for the formation of voluminous granitoids, mafic rocks with complex compositions, and the association of adakite + high-Mg andesite + boninite + Nb-enriched basalt, but also for the coeval high-T, low-P metamorphism.SUN Min LONG XiaoPing CAI KeDa JIANG YingDe WANG BuYun YUAN Chao ZHAO GuoChun XIAO WenJiao WU FuYuan 2009Science China Earth Sciences2009,52,9:33

10Different treatment strategies and molecular features between right-sided and left-sided colon cancers显示文摘The colon is derived from the embryological midgut and hindgut separately,with the right colon and left colon having different features with regards to both anatomical and physiological characteristics.Cancers located in the right and left colon are referred to as right colon cancer(RCC) and left colon cancer(LCC),respectively,based on their apparent anatomical positions.Increasing evidence supports the notion that not only are there differences in treatment strategies when dealing with RCC and LCC,but molecular features also vary between them,not to mention the distinguishing clinical manifestations.Disease-free survival after radical surgery of both RCC and LCC are similar.In the treatment of RCC,the benefit gained from adjuvant FOLFIRI chemotherapy is superior,or at least similar,to LCC,but inferior to LCC if FOLFOX regimen is applied.On the other hand,metastatic LCC exhibits longer survival than that of RCC in a palliative chemotherapy setting.For KRAS wild-type cancers,LCC benefits more from cetuximab treatment than RCC.Moreover,advanced LCC shows a higher sensitivity to bevacizumab treatment in comparison with advanced RCC.Significant varieties exist at the molecular level between RCC and LCC,which may serve as the cause of all apparent differences.With respect to carcinogenesis mechanisms,RCC is associated with known gene types,such as MMR,KRAS,BRAF,and mi RNA-31,while LCC is associated with CIN,p53,NRAS,mi RNA-146 a,mi RNA-147 b,and mi RNA-1288.Regarding protein expression,RCC is related to GNAS,NQO1,telomerase activity,P-PDH,and annexin A10,while LCC is related to Topo I,TS,and EGFR.In addition,separated pathways dominate progressionto relapse in RCC and LCC.Therefore,RCC and LCC should be regarded as two heterogeneous entities,with this heterogeneity being used to stratify patients in order for them to have the optimal,current,and novel therapeutic strategies in clinical practice.Additional research is needed to uncover further differences between RCC and LCC.Hong Shen Jiao Yang Qing Huang Meng-Jie Jiang Yi-Nuo Tan Jian-Fei Fu Li-Zhen Zhu Xue-Feng Fang Ying Yuan 2015World Journal of Gastroenterology2015,21,21:33
11Gynura root induces hepatic veno-occlusive disease:A case report and review of the literature显示文摘Gynura root has been used extensively in Chinese folk medicine and plays a role in promoting microcirculation and relieving pain.However,its hepatic toxicity should not be neglected.Recently,we admitted a 62-year old female who developed hepatic veno-occlusive disease(HVOD)after ingestion of Gynura root.Only a few articles on HVOD induced by Gynura root have been reported in the literature.It is suspected that pyrrolizidine alkaloids in Gynura root might be responsible for HVOD.In this paper,we report a case of HVOD and review the literature.Ning Dai Ying-Cong Yu Tian-Hua Ren Jia-Guo Wu Yuan Jiang Lai-Gen Shen Jing Zhang 2007World Journal of Gastroenterology2007,13,10:27
12CT and MRI diagnosis of hepatic epithelioid hemangioendothelioma显示文摘BACKGROUND:Hepatic epithelioid hemangioendothelioma (EHE)is a rare,low-grade malignant vascular tumor.Although its unusual imaging and pathologic findings are being recognized with increasing frequency,diagnosis is still difficult.This study aimed to analyze the CT and MRI features of hepatic EHE with a pathological study in order to improve the diagnostic accuracy and knowledge of this disease in daily practice. METHODS:Nine patients with hepatic EHE confirmed pathologi- cally underwent plain and dynamic contrast-enhanced multi- detector row CT examination.Of these patients,four under- went additional MRI(plain T1-weighted imaging(T1WI),T2- weighted imaging(T2WI),and dynamic contrast-enhanced scanning)and one had selective hepatic arteriography.The imaging findings were reviewed retrospectively together with the pathological results. RESULTS:A total of 79 lesions,ranging from 3.0 to 44.6 mm in maximum diameter,with an average of 16.8±7.1 mm,were found in various segments of the liver.Thirty of the 79 lesions grew adjacent to the hepatic capsule.In the 4 patients receiving MRI,39 lesions were found with low signal intensity on unenhanced T1WI and intermediate to high signal intensity on T2WI.The'capsular retraction'sign was found in all the 4 patients.Nine of the 39 lesions showed the'halo'sign after contrast enhancement on MRI.Of the 79 lesions(hypodense nodules)in the 9 patients shown by unenhanced plain CT,26 were confluent.Calcification was found in 2 patients and the 'capsular retraction'sign in 7.Thirty-eight of the 79 lesions demonstrated the'halo'sign after contrast enhancement on CT,and this sign was more clearly demonstrated in the portal venous phase.In one patient,selective hepatic arteriography showed patchy stain in the peripheral liver parenchyma with small vessels around them.Histology in all patients revealed proliferation of abnormal fibrous tissue and vessel-like structures scattered with irregular epithelioid cells having a signet ring-like structure.Immunohistochemically,all patients were positive for CD34,4 were positive for CD31,and 3 were positive for factorⅧ-related antigen. CONCLUSIONS:Hepatic EHE may manifest as solitary or diffuse nodular lesions with a predilection for peripheral subcapsular growth and nodular confluence,together with the 'halo'and'capsular retraction'signs.These imaging findings can help to improve the diagnostic accuracy of this rare hepatic tumor.Lin, Jiang Ji, Yuan 2010Hepatobiliary & Pancreatic Diseases International2010,9,2:26
13Single-incision vs three-port laparoscopic cholecystectomy:Prospective randomized study显示文摘AIM:To compare the clinical outcome of single-inci-sion laparoscopic cholecystectomy(SILC)with threeport laparoscopic cholecystectomy(TPLC). METHODS:Between 2009 and 2011,one hundred and two patients with symptomatic benign gallbladder diseases were randomized to SILC(n=49)or TPLC (n=53).The primary end point was post operative pain score(at 6 h and 7 d).Secondary end points were blood loss,operation duration,overall complications,postoperative analgesic requirements,length of hospital stay,cosmetic result and total cost.Surgical techniques were standardized and all operations were performed by one experienced surgeon,who had performed more than 500 laparoscopic cholecystectomies. RESULTS:One patient in the SILC group required conversion to two-port LC.There were no open conversions or major complications in either treatment groups.There were no differences in terms of esti-mated blood loss(mean±SD,14±6.0 mL vs 15±4.0 mL),operation duration(mean±SD,41.8±17.0 min vs 38.5±22.0 min),port-site complications(contusion at incision:5 cases vs 4 cases and hematoma at inci- sion:2 cases vs 1 case),total cost(mean±SD,12 075 ±1047 RMB vs 11 982±1153 RMB)and hospital stay (mean±SD,1.0±0.5 d vs 1.0±0.2 d),respectively. TPLC had a significantly worse visual analogue pain score at 8 h after surgery(mean±SD,3.5±1.6 vs 2.0 ±1.5),however,the scores were similar on day 7(mean ±SD,2.5±1.4 vs 2.0±1.3).Cosmetic satisfaction, as determined by a survey at 2 mo follow-up favored SILC(mean±SD,8±0.4 vs 6±0.2). CONCLUSION:SILC is a safe and feasible approach in selected patients.The main advantages are a better cosmetic result and less pain.Ming-Xin Pan Ze-Sheng Jiang Yuan Cheng Xiao-Ping Xu Zhi Zhang Jia-Sheng Qin Guo-Lin He Ting-Cheng Xu Chen-Jie Zhou Hai-Yan Liu Yi Gao 2013World Journal of Gastroenterology2013,19,3:24
14A step metallogenetic model for gold deposits in the northwestern Shandong Peninsula, China显示文摘Based on our study of the nature and variation of mineralization-controlling faults in their deep extension and the spatial distribution of gold orebodies in the northwestern Shandong Peninsula (NSP), here we propose that the gold deposits in the Jiaojia gold belt are controlled by listric faults and the gold deposits in the NSP are controlled by extensional fault system. We also suggest that there is a multiple mineralization space in the deep part of the NSP gold belt. As steps or benches occur along the deep extention of the listric fault where its dipping angle changes from steep to gentle, a number of gold deposits are correspondingly distributed as a steplike pattern, which is named as a step metallogenetic model for gold deposits in the NSP. The gold deposits in Shandong Peninsula were formed in the Cretaceous when the crust in the region experienced extention and thinning following the strong collision between North China Plate and Yangtze Plate during the Triassic. Crust anataxis, fluid remobilization, and extention-detachement of the crust are the leading factors for the gold mineralization.SONG MingChun YI PiHou XU JunXiang CUI ShuXue SHEN Kun JIANG HongLi YUAN WenHua WANG HuaJiang 2012Science China Earth Sciences2012,55,6:21

17Relationship between Two Blood Stasis Syndromes and Inflammatory Factors in Patients with Acute Coronary Syndrome显示文摘Objective: To investigate the relationship between inflammatory factors and two Chinese medicine(CM) syndrome types of qi stagnation and blood stasis(QSBS) and qi deficiency and blood stasis(QDBS) in patients with acute coronary syndrome(ACS). Methods: Sixty subjects with ACS, whose pathogenesis changes belongs to qi disturbance blood stasis syndrome, were divided into 2 groups: 30 in the QSBS group and 30 in the QDBS group. The comparative analysis on them was carried out through comparing general information, coronary angiography and inflammatory factors including intracellular adhesion molecule-1(ICAM-1), chitinase-3-like protein 1(YKL-40) and lipoprotein-associated phospholipase A2(Lp-PLA2). Results: Compared with the QSBS group, Lp-PLA2 and YKL-40 levels in the QDBS group showed no-significant difference(P>0.05); ICAM-1 was significantly higher in the QDBS group than in the QSBS group in the pathological processes of qi disturbance and blood stasis syndrome of ACS(P<0.05). Conclusion: Inflammatory factor ICAM-1 may be an objective basis for syndrome typing of QSBS and QDBS, which provides a research direction for standardization research of CM syndrome types.MA Cai-yun LIU Jing-hua LIU Jian-xun SHI Da-zhuo XU Zhen-ye WANG Shao-ping JIA Min ZHAO FU-hai JIANG YUE-rong MA Qin PENG Hong-yu LU Yuan ZHENG Ze REN Feng-xue 2017Chinese Journal of Integrative Medicine2017,23,11:19
18Infection with novel coronavirus(SARS-CoV-2)causes pneumonia in Rhesus macaques显示文摘The 2019 novel coronavirus(SARS-CoV-2)outbreak is a major challenge for public health.SARS-CoV-2 infection in human has a broad clinical spectrum ranging from mild to severe cases,with a mortality rate of^6.4%worldwide(based on World Health Organization daily situation report).However,the dynamics of viral infection,replication and shedding are poorly understood.Here,we show that Rhesus macaques are susceptible to the infection by SARS-CoV-2.After intratracheal inoculation,the first peak of viral RNA was observed in oropharyngeal swabs one day post infection(1 d.p.i.),mainly from the input of the inoculation,while the second peak occurred at 5 d.p.i.,which reflected on-site replication in the respiratory tract.Histopathological observation shows that SARS-CoV-2 infection can cause interstitial pneumonia in animals,characterized by hyperemia and edema,and infiltration of monocytes and lymphocytes in alveoli.We also identified SARS-CoV-2 RNA in respiratory tract tissues,including trachea,bronchus and lung;and viruses were also re-isolated from oropharyngeal swabs,bronchus and lung,respectively.Furthermore,we demonstrated that neutralizing antibodies generated from the primary infection could protect the Rhesus macaques from a second-round challenge by SARS-CoV-2.The non-human primate model that we established here provides a valuable platform to study SARS-CoV-2 pathogenesis and to evaluate candidate vaccines and therapeutics.Chao Shan Yan-Feng Yao Xing-Lou Yang Yi-Wu Zhou Ge Gao Yun Peng Lian Yang Xue Hu Jin Xiong Ren-Di Jiang Hua-Jun Zhang Xiao-Xiao Gao Cheng Peng Juan Min Ying Chen Hao-Rui Si Jia Wu Peng Zhou Yan-Yi Wang Hong-Ping Wei Wei Pang Zheng-Fei Hu Long-Bao Lv Yong-Tang Zheng Zheng-Li Shi Zhi-Ming Yuan 2020Cell Research2020,30,8:19
19First observation of mesospheric and thermospheric winds by a Fabry-Perot interferometer in China显示文摘A Fabry-Perot interferometer,funded by the Meridian Project in China,was deployed at the Xinglong station(40.2°N,117.4°E) of the National Astronomical Observatories in Hebei Province,China.The instrument has been operating since April 2010,measuring mesospheric and thermospheric winds.The first observational data of winds at three heights in the mesosphere and thermosphere were analyzed,demonstrating the capacity of this instrument to aid basic scientific research.The wavelengths of three airglow emissions were OH892.0,OI 557.7,and OI 630.0 nm,which corresponded to heights of 87,98,and 250 km,respectively.Three 38-day data sets of horizontal winds,from April 5,2010 to May 12,2010,show clear day-to-day variations at the same height.The minimum and maximum meridional winds at heights of 87,98,and 250 km were-16.5 to 8.7 m/s,-24.4 to 15.9 m/s,and-43.6 to 1.5 m/s.Measurements of zonal winds were-5.4 to 7.6 m/s,2.3 to 23.0 m/s,and-22.6 to 49.3 m/s.The average data from the observations was consistent with the data from HWM93.The wind data at heights of 87 and 98 km suggest a semi-diurnal oscillation,clearly consistent with HWM93 results.Conversely there was a clear discrepancy between the observations and the model at 250 km.In general,this Fabry-Perot interferometer is a useful ground-based instrument for measuring mesospheric and thermospheric winds at middle latitudes.YUAN Wei XU JiYao MA RuiPing WU Qian JIANG GuoYing GAO Hong LIU Xiao CHEN SunZheng 2010Chinese Science Bulletin2010,55,35:18
