| 1 | Late Cretaceous-Cenozoic exhumation history of Tiantangzhai region of Dabieshan Orogen: Constraints from (U-Th)/He and fission track analysis显示文摘Integrated fission track and (U-Th)/He analysis is carried out on 6 apatite and 6 zircon samples from a near vertical section in The Tiantangzhai region at the core of the present Dabieshan orogen. The result shows that the region experienced cooling/exhumation during the Late Cretaceous and Early Tertiary period. Age-elevation relationships for different dating systems and different minerals suggest a pulse of rapid exhumation at ~110 Ma before present, preserved in the structurally highest samples. At lower elevations, ages begin to decrease with decreasing elevation, suggesting lower exhumation rates since 90 Ma. Two periods of different exhumation rates are identified since 90 Ma. The average apparent exhumation rate for the period of 43.4-22.5 is 0.062 km/Ma, whereas that for the period of 76.4-47.4 Ma is 0.039 km/Ma. | ZHOU Zuyi XU Changhai P. W. Reiners YANG Fengli R. A.

| 3 | Ultraselective carbon molecular sieve membrane for hydrogen purification显示文摘Hydrogen is a green clean fuel and chemical feedstock. Its separation and purification from hydrogencontaining mixtures is the key step in the production of hydrogen with high purity(>99.99%). In this work, carbon molecular sieve(CMS) membranes with ultrahigh permselectivity for hydrogen purification were fabricated by high-temperature(700–900 ℃) pyrolysis of polymeric precursor of phenolphthaleinbased cardo poly(arylene ether ketone)(PEK-C). The evolution of the microstructural texture and ultramicroporous structure and gas separation performance of the CMS membrane were characterized via TG-MS, FT-IR, XRD, TEM, CO2 sorption analysis and gas permeation measurements. CMS membranes prepared at 700 ℃ exhibited amorphous turbostratic carbon structures and high H2 permeability of 5260 Barrer with H2/CH4, H2/N2 and H2/CO selectivities of 311, 142, 75, respectively. When carbonized at900 ℃, the CMS membrane with ultrahigh H2/CH4 selectivity of 1859 was derived owing to the formation of the dense and ordered carbon structure. CMS membranes with ultrahigh permselectivity exhibit an attractive application prospect in hydrogen purification. | Ruisong Xu Liu He Lin Li Mengjie Hou Yongzhao Wang Bingsen Zhang Changhai Liang Tonghua Wang | 2020 | Journal of Energy Chemistry2020，29，11： | 8 |
| 4 | Distribution of cagG gene in Helicobacter pylori isolates from Chinese patients with different gastroduodenal diseases and its clinical and pathological significance显示文摘AIM: To determine the distribution of cagG gene of Helicobacter pylori(Hpylori) isolates cultured from patients with various digestive diseases and its relationship with gastroduodenal diseases.METHODS: cagG was amplified by polymerase chain reaction in 145 H pylori isolates cultured from patients with chronic gastritis (n=72), duodenal ulcer (n=48), gastric ulcer (n=17), or gastric and duodenal ulcer (n=8), and the relationship between cagGstatus and the grade of gastric mucosal inflammation was determined.RESULTS: cagG was present in 91.7% of the 145 H pylori isolates, with the rates were 90.3%, 93.8%, 88.2% and 100.0%, respectively, in those from patients with chronic gastritis, duodenal ulcer, gastric ulcer, and gastric and duodenal ulcer. There was no significant difference among the four groups (P>0.05). The average grade of gastric mucosal inflammation in the antrum and corpus was 1.819±0.325and 1.768±0.312, respectively in cagG positive patients,whereas the average inflammation grade was 1.649±0.297,1.598±0.278 respectively in cagG negative cases (P>0.05).CONCLUSION: cagG gene of H pylori was quite conservative,and most H pylori strains in Chinese patients were cagG positive.cagG status was not related to clinical outcome or the degree of gastric mucosal inflammation. Therefore, cagG can notbe used as a single marker for discrimination of H pylori strains with respect to a specific digestive disease. | Can Xu Zhao-Shen Li Zhen-Xing Tu Guo-Ming Xu Yan-Fang Gong Xiao-Hua Man, Department of Gastroenterology, Changhai Hospital, Second Military Medical University, Shanghai 200433, China | 2003 | World Journal of Gastroenterology2003，9，10： | 8 |
| 5 | Modelling of low-temperature exhumation rate in Dabie Mountain based on (U-Th)/He and fission-track thermochronological data显示文摘While the high-temperature exhumation process in the Dabie Mountain has been well documented, the low-temperature exhumation of this area since Cretaceous, especially since Late Cretaceous, is relatively less studied. Low-temperature thermochronology provides one of the important approaches to solve this problem. Based on the data of fission track and (U-Th)/He analysis of apaptites and zircons from the granitoid and metamorphic rocks in the Dabie Mountain, this paper applies Mancktelow’s and Braun’s methods to estimating the exhumation rates and to drawing the regional differential exhumation pattern since Cretaceous, especially since Late Cretaceous by taking into consideration factors such as heat transport, heat advection, topography and heat production, which could influence geothermal field in the shallow crust. Since Cretaceous, the exhumation rate (0.08-0.10 km/Ma) in the region around Tiantangzhai and in the south of Tanlu fault zone is larger than the rate (0.04-0.07 km/Ma) in other areas of the Dabie Mountain. The regional differential exhumation pattern might be related to the push-up effect caused by differential strike-slip movement along NNE-trending faults. | DING Ruxin ZHOU Zuyi XU Changhai LIU Yuzhu CHENG Hao XU Fei | 2006 | Science China Earth Sciences2006，49，10： | 5 |
| 6 | Killing effects of cytosine deaminase gene mediated by adenovirus vector on human pancreatic cancer cell lines in vitro显示文摘OBJECTIVE: To evaluate the killing effects of the cytosine deaminase (CD) gene mediated byadenovirus vector on human pancreatic cancer cell lines in vitro.METHODS: The CD gene was cloned into pAdTrack-CMV-CD, and pAdTrack-CMV-CD and pAdEasy-lwere recombinated in bacteria. The newly recombinated Ad-CD containing green fluoreseent protein(GFP) was propagated in 293 cells and purified by cesium chloride gradient centrifugation. Humanpancreatic cancer cell lines Patu8988 and SW1990 were infected with this virus, then 5-FC was added.XTT assay was used to estimate relative numbers of viable cells.RESULTS: The positive clones were selected by using endonuclease to digest the combinatants and theconcentration of viral liquids containing the CD gene was 2×1O11 pfu/ml. It was found that significantcytotoxic activities were possesscd by 5-FC for the CD gene transduced pancreatic cell lines, but littleeffects exerted on the nontransduced pancreatic carcinoma cells.CONCLUSIONS: The CD gene mediated by adenovirus with a high infectivity is efficient for genetherapy of pancreatic carcinoma cell lines. These data demonstrate the therapeutic efficacy of an enzymeprodrug strategy in experimental pancreatic cancer. | Zhao-Shen Li Xue Pan Guo-Ming Xu Long Cui Guan-Rong Dai Yan-Fang Gong Zhen-Xing Tu the Department of Gastroenterology Department of General Surgery Changhai Hospital, Second Military Medical University, Shanghai 200433, China | 2003 | Hepatobiliary & Pancreatic Diseases International2003，2，1： | 5 |
| 7 | The Southward Extension of Cathaysia Block: Evidence from Zircon UPb Dates of Borehole Volcanics in the Northern South China Sea显示文摘Five Paleogene volcanics sampled from the northern South China Sea were analyzed via LA-ICP-MS zircon U-Pb dating,including basalt and andesite from Borehole SCSV1 and volcanic agglomerate from Borehole SCSV2,respectively.A total of 162 zircon U-Pb dates for them cover an age range from Neoarchean to Eocene,in which the pre-Paleocene data dominate.The Paleogene dates of 62.5±2.2 Ma and 42.1±2.9 Ma are associated with two igneous episodes prior to opening of South China Sea basin.Those pre-Paleocene zircons are inherited zircons mostly with magmatogenic oscillatory zones,and have REE features of crustal zircon.Zircon U-Pb dates of 2518–2481 Ma,1933– 1724 Ma,and 1094–1040 Ma from the SCSV1 volcanics,and 2810–2718 Ma,2458–2421 Ma,and 1850 –993.4 Ma from the SCSV2 volcanics reveal part of Precambrian evolution of the northern South China Sea,well comparable with age records dated from the Cathaysia block.The data of 927.0±6.9 Ma and 781±38 Ma dated from the SCSV2 coincide with amalgamation between Yangtze and Cathaysia blocks and breakup of the Rodinia,respectively.The age records of Caledonian orogeny from the Cathaysia block are widely found from our volcanic samples with concordant mean ages of 432.0±5.8 Ma from the SCSV1 and of 437±15 Ma from the SCSV2.The part of the northern South China Sea resembling the Cathaysia underwent Indosinian and Yanshannian tectonothermal events.Their age signatures from the SCSV1 cover 266.5±3.5 Ma,241.1±6.0 Ma,184.0±4.2 Ma,160.9±4.2 Ma and 102.8±2.6 Ma,and from the SCSV2 are 244±15 Ma,158.1±3.5 Ma,141±13 Ma and 96.3±2.1 Ma.Our pre-Paleogene U-Pb age spectra of zircons from the borehole volcanics indicate that the northern South China Sea underwent an evolution from formation of Precambrian basement,Caledonian orogeny,and Indosinian orogeny to Yanshannian magmatism.This process can be well comparable with the tectonic evolution of South China,largely supporting the areas of the northern South China Sea as part of southward extension of the Cathaysia. | XU Changhai QUE Xiaoming SHI Hesheng ZHOU Zuyi MA Changqian | 2013 | Acta Geologica Sinica(English Edition)2013，87，5： | 5 |
| 8 | Effects of Changtai granules, a traditional compound Chinese medicine, on chronic trinitrobenzene sulfonic acid-induced colitis in rats显示文摘AIM: To study the effects of Changtai granules (CTG), a traditional compound Chinese medicine, on chronic trinitrobenzene sulfonic acid-induced colitis in rats. METHODS: Healthy adult Sprague-Dawley (SD) rats of both sexes, weighing 250-300 g, were employed in the present study. The rat colitis models were induced by 2, 4,6-trinitrobenzene sulfonic acid (TNBS) enemas at a concentration of 100 mg/kg in 50% ethanol. The experimental animals were randomly divided into dexamethasone (DX) treatment, CTG treatment, and model control groups, which were intracolicly treated daily with DX (0.2 mg/kg), CTG at doses of 2.9, 5.7 and 11.4 g crude drug/kg, and the equal amount of saline respectively from 6 h following induction of the colitis in rats inflicted with TNBS to the end of study. A normal control group of rats treated without TNBS but saline enema was also included in the study. After 3 wk of treatment, the animals were assessed for colonal inflammatory and ulcerative responses with respect to mortality, frequency of diarrhea, histology and myeloperoxidase activity (MPO).RESULTS: The therapeutic effect of CTG on ulcerative colitis (UC) was better than DX. CTG effectively inhibited the activity of granulocytes, macrophages and monocytes in a dosedependent manner. Also it reduced MPO and formation of inflammation in colonic mucosal tissue. Furthermore, administration of CTG significantly prevented body mass loss and death, and decreased frequency of diarrhea in UC rats, when compared with the model control group rats.CONCLUSION: CTG would prove to be an ideal drug for chronic UC, and is warranted to be studied further. | Yong-Bing Cao,Jun-Dong Zhang,Lan Yan,De-Jun Wang,Xin-Ming Jia,Ping-Hui Gao,Ming-He Cheng,Zheng Xu,Yan Wang,Yuan-Ying Jiang,Department of Pharmacology,School of Pharmacy,Second Military Medical University,Shanghai 200433,China Ya-Ying Diao,Department of Pharmacy,Changhai Hospital,Second Military Medical University,Shanghai 200433,China | 2005 | World Journal of Gastroenterology2005，11，23： | 5 |
| 9 | Tectonic Evolution of Southeast Central Asian Orogenic Belt: Evidence from Geochronological Data and Paleontology of the Early Paleozoic Deposits in Inner Mongolia显示文摘In this study, we present detrital zircon U-Pb dating and paleontological data for the newly identified Ayadeng Formation in the northern margin of the North China Block(NCB) and Xibiehe Formation(molasse) in the Bainaimiao arc belt(BAB), which could provide strong evidence indicating the affinity of the BAB and the evolution of the southeast Central Asian orogenic belt(CAOB). Zircon U-Pb data of siltstone samples and paleontological data indicate the Ayadeng Formation dates back to the Early Ordovician. Although its location is near the NCB, its zircon age spectra and paleontology share a closer affinity with those of Tarim and NE Gondwana, as the U-Pb data suggest an age range of 490–2 192 Ma(peak age=629, 788, 965 and 1 935 Ma), and similar gastropod fossils are found in Tarim and NE Gondwana. The U-Pb ages of meta-sandstone samples in the Xuniwusu Formation indicate a shared inheritance with the Ayadeng Formation(before 440 Ma), and the U-Pb ages of sandstone samples in the Xibiehe Formation are concentrated, with age peaks centered at ca. 420 Ma. Fossil corals occur in these two formations, and their age components also indicate a collisional setting. Therefore, it is speculated that the BAB drifted away from Tarim or NE Gondwana during the Ordovician and became attached to northern NCB between 440–420 Ma as an exotic terrane. During the Early Paleozoic, there may have occurred a collision between an arc and a continental block. | Shijie Wang Shichao Li Wenjie Li Zhongyuan Xu Jinfeng Zhang Changhai Li Qiang Shi Yang Liu Wenlong Wang Qingbin Guan | 2020 | Journal of Earth Science2020，31，4： | 4 |
| 10 | Novel passive localization algorithm based on double side matrix-restricted total least squares显示文摘In order to solve the bearings-only passive localization problem in the presence of erroneous observer position, a novel algorithm based on double side matrix-restricted total least squares (DSMRTLS) is proposed. First, the aforementioned passive localization problem is transferred to the DSMRTLS problem by deriving a multiplicative structure for both the observation matrix and the observation vector. Second, the corresponding optimization problem of the DSMRTLS problem without constraint is derived, which can be approximated as the generalized Rayleigh quotient minimization problem. Then, the localization solution which is globally optimal and asymptotically unbiased can be got by generalized eigenvalue decomposition. Simulation results verify the rationality of the approximation and the good performance of the proposed algorithm compared with several typical algorithms. | Xu Zheng Qu Changwen Wang Changhai | 2013 | Chinese Journal of Aeronautics2013，26，4： | 4 |
| 11 | Direct reprogramming of induced neural progenitors: a new promising strategy for AD treatment显示文摘Alzheimer’s disease(AD)is a prominent form of dementia,characterized by aggregation of the amyloidβ-peptide(Aβ)plaques and neurofibrillary tangles,loss of synapses and neurons,and degeneration of cognitive functions.Currently,although a variety of medications can relieve some of the symptoms,there is no cure for AD.Recent breakthroughs in the stem cell field provide promising strategies for AD treatment.Stem cells including embryonic stem cells(ESCs),neural stem cells(NSCs),mesenchymal stem cells(MSCs),and induced pluripotent stem cells(iPSCs)are potentials for AD treatment.However,the limitation of cell sources,safety issues,and ethical issues restrict their applications in AD.Recently,the direct reprogramming of induced neural progenitor cells(iNPCs)has shed light on the treatment of AD.In this review,we will discuss the latest progress,challenges,and potential applications of direct reprogramming in AD treatment. | Siqiang Lai Min Zhang Dongsheng Xu Yiying Zhang Lisha Qiu Changhai Tian Jialin Charlie Zheng | 2015 | Translational Neurodegeneration2015，4，1： | 4 |
| 12 | Detrital Zircon U–Pb Geochronology and Provenance of Bayan Obo Group, Northern Margin of North China Craton: New Implications for the Position of NCC in Rodinia显示文摘The paleoposition of North China Craton in Rodinia has long been in controversial. This paper mainly focuses on the U-Pb geochronological studies of detrital zircons obtained from Bayan Obo Group exposed in the Shangdu area, Inner Mongolia, aiming to provide more information for interprating this problem. Based on the acquired data, this paper comes to the following conclusions. Firstly, the depositional age of Bayan Obo Group might be from Meso- to Neoproterozoic according to the zircons U-Pb dating results. The lower succession of this group, namely Dulahala and Jianshan formations deposited between 1800 and 1650 Ma. The Halahuogete and Bilute formations deposited between 1500 and 1350 Ma. For Baiyinbaolage and Hujiertu formations, their depositional age was 1250-900 Ma. Secondly, for the provenance of Bayan Obo Group, this paper believes detrital zircons with age of 2.51-2.71 Ga and 2.00-2.48 Ga were from Guyang, Xi Ulanbulang and Zhuozi area;the Khondalite Belt provided detrital zircons with age of 1.95-1.80 Ga;zircons with age of 1.60-1.75 Ga might come from granitic rocks in Miyun Area. The magmatism after 1.60 Ga was rarely recorded in the NCC, therefore those zircons with ages younger than 1.60 Ga might come from outside of NCC. The magmatism with the same age existed in Baltic, Amazonia and Laurentia. Based on previous paleomagnetic researches, this paper proposes that NCC might receive detritus from Baltic during 1560-1350 Ma and had affinity with Laurentia and Amazonia at ~0.9 Ga in Rodinia. Baltic, Amazonia and Laurentia might be potential provenances for non-NCC detritus in Bayan Obo Group. | LI Changhai LIU Zhenghong XU Zhongyuan DONG Xiaojie LI Pengchuan SHI Qiang WANG Shijie | 2019 | Acta Geologica Sinica(English Edition)2019，93，5： | 4 |
| 13 | Multi-dimensional overall regulatory modes and threshold values for water cycle of the Haihe River Basin显示文摘In this study, a multi-dimensional critical regulatory criteria and decision-making mechanism based on the scientific cognition of multi-dimensional attributes and characteristics of the water cycle was proposed. This system was functioned by deeply discriminating the nature-society binary characteristics of the five-dimensional characteristics of the water cycle system of the Haihe River Basin (water resources, economy, society, ecology, and environment) under the influence of high-intensity human activities and hydrological changes and by analyzing the organic interactive relationships between the five dimensions and their overall effect on the water cycle. A GDP calculation model was constructed in this study by adjusting the water environment for water resources, after which five-dimensional normalization objective functions were established for multi-objective analysis to carry out trade-off analysis of multi-dimensional regulatory indexes. In addition, synergetic theory, entropy theory and dissipation structure theory were introduced to construct an evaluation model for multi-dimensional regulatory schemes. A water cycle multi-dimensional critical overall regulatory model system was also established. This system consisted of a multi-objective macroeconomic model (DAMOS), water resource allocation model based on rules (ROWAS), evaluation model for WEDP (EMW) and multi-dimensional regulatory scheme evaluation model (SEAMUR) as the main body. To address the national demands faced by the Haihe River Basin as a result of combinatorial schemes for different hydrological series and water amounts diverted by the south-to-north water diversion project, this study adopted a hierarchy progression method to set up the technologies, investigated multi-dimensional overall regulatory methods, proposed an overall regulation threshold value for the water cycle of the Haihe River Basin, and recommended corresponding five-dimensional regulatory schemes. | GAN Hong WANG Lin CAO YinBai YOU JinJun GAN ZhiGuo QIN ChangHai HE Shan XU Kai | 2013 | Chinese Science Bulletin2013，58，27： | 4 |

| 15 | Detection of K-ras gene mutation at codon 12 by pancreatic duct brushing for pancreatic cancer显示文摘OBJECTIVE: To assess the diagnostic value of endoscopic pancreatic duct brushing in detecting mutationof the K-ras gene at codon 12 in cytologic specimens from patients with pancreatic cancer.METHODS: Thirty-five patients treated at Changhai Hospital, Shanghai between 1999 and 2001 wereenrolled. Their cells obtained by pancreatic duct brushing during endoscopic retrogradetholangiopancreatography (ERCP) were suspended with phosphate buffer solution (PBS). DNA of thecells was extracted and mutation of the K-ras gene at codon 12 detected by means of PCR-SSCP.RESULTS: The K-ras gene mutation rate of pancreatic cancer was 70%, which was higher than that ofchronic pancreatitis (14%, P<0.05). K-ras gene mutation was not found in patients with pancreaticcystorcarcinoma and duodenum carcinoma. As to the location of pancreatic cancer, no significantdifference was observed between the head, the body and tail. The sensitivity, specificity, accuracy ofpancreatic duct brushing in detecting pancreatic cancer was 70%, 94%, and 83%, respectively.CONCLUSION: K-ras analysis of pancreatic brushing samples is helpful in the diagnosis of patients withearly pancreatic cancer. | Feng Liu Zhao-Shen Li Guo-Ming Xu Zhen-Xing Sun Guo-Xiong Zhou Xue-Xin Ren Zhen-Xing Tu Yan-Fang Gong the Department of Gastroenterology, Changhai Hospital, Second Military Medical Univercity, Shanghai 200433, China | 2003 | Hepatobiliary & Pancreatic Diseases International2003，2，2： | 2 |
| 16 | Novel passive localization algorithm based on weighted restricted total least square显示文摘A novel multi-observer passive localization algorithm based on the weighted restricted total least square (WRTLS) is proposed to solve the bearings-only localization problem in the presence of observer position errors. Firstly, the unknown matrix perturbation information is utilized to form the WRTLS problem. Then, the corresponding constrained optimization problem is transformed into an unconstrained one, which is a generalized Rayleigh quotient minimization problem. Thus, the solution can be got through the generalized eigenvalue decomposition and requires no initial state guess process. Simulation results indicate that the proposed algorithm can approach the Cramer-Rao lower bound (CRLB), and the localization solution is asymptotically unbiased. | Changwen Qu Zheng Xu Changhai Wang | 2013 | Journal of Systems Engineering and Electronics2013，24，4： | 2 |
