| 1 | Effect of Liuweibuqi capsule, a Chinese patent medicine, on the JAK1/STAT3 pathway and MMP9/TIMP1 in a chronic obstructive pulmonary disease rat model显示文摘OBJECTIVE: To observe effect of Liuweibuqi Capsule, a Traditional Chinese Medicine(TCM), on the janus kinase(JAK)/signal transducer and activator of transcription(STAT) pathway and matrix metalloproteinases(MMPs) in a chronic obstructive pulmonary disease(COPD) rat model with lung deficiency in terms of TCM's pattern differentiation.METHODS: Rats were randomly divided into a normal group, model group, Liuweibuqi group, Jinshuibao group, and spleen aminopeptidase group(n=10). Aside from the normal group, all rats were ex-posed to smoke plus lipopolysaccharide tracheal instillation to establish the COPD model with lung deficiency. Models were established after 28 days and then the normal and model groups were given normal saline(0.09 g/kg), Liuweibuqi group was given Liuweibuqi capsule(0.35 g/kg), Jinshuibao group was given Jinshuibao capsules(0.495 g/kg), and the spleen group was given spleen aminopeptidase(0.33 mg/kg), once a day for 30 days. Changes in symptoms, signs, and lung histology were observed. Lung function was measured with a spirometer. Serum cytokines were detected using enzyme-linked immunosorbent assay, and changes in the JAK/STAT pathway, MMP-9, and MMPs inhibitor1(TIMP1) were detected by immunohistochemistry, RT-PCR, and western blotting, respectively.RESULTS: Compared with the normal group, lung tissue was damaged, and lung function was reduced in the model control group. Additionally, the levels of interleukin(IL)-1β, γ interferon(IFN-γ), and IL-6 were higher, while IL-4 and IL-10 were lower in the model control group than those in the normal group. The expressions of JAK1, STAT3, p-STAT3,and MMP-9 m RNA and protein in lung tissue were higher, and TIMP1 m RNA and protein was lower in the model group compared with the normal group.After treatment, compared with the model group,the expression of inflammatory cytokines was lower in each treatment group, and expressions of JAK/STAT pathway, MMPs were lower. Compared with the positive control groups, the Jinshuibao and spleen aminopeptidase groups, lung function was better, and JAK1, STAT3, and p-STAT3 protein were lower and TIMP1 was higher in the Liuweibuqi group.CONCLUSION: Liuweibuqi capsules can improve the symptoms of COPD possibly by regulating the expression of the JAK1/STAT3 pathway and MMP9/TIMP1. | Wang Chengyang Li Zegen Liu Xiangguo Peng Qinghe Li Fang Li Da Wang Chuanbo | 2015 | Journal of Traditional Chinese Medicine2015，35，1： | 23 |
| 2 | The development of China's Yangtze River Economic Belt:how to make it in a green way?显示文摘The Yangtze River is one of the largest and longest rivers in Asia.The river originates in the Tibet-Qinghai Plateau(headwater reach),passes through the mountainous provinces of Sichuan,Yunnan and Chongqing(upper reach),flows into the Central Plain(middle reach)and Lower Plain(lower reach),and finally empties into the East China Sea in Shanghai(estuary).The Yangtze River Economic Belt(YREB;Fig.1)has a surface area of 2.1 | Yushun Chen Shuanghu Zhang Desheng Huang Bai-Lian Li Junguo Liu Wenjin Liu Jing Ma Fang Wang Yong Wang Shengjun Wu Yegang Wu Jinyue Yan Chuanbo Guo Wei Xin Hao Wang | 2017 | Science Bulletin2017，62，9： | 20 |
| 3 | Trends in the Different Grades of Precipitation over South China during 1960–2010 and the Possible Link with Anthropogenic Aerosols显示文摘Using observed daily precipitation data to classify five levels of rainy days by strength in South China(SC), with an emphasis on the Pearl River Delta(PRD) region, the spatiotemporal variation of different grades of precipitation during the period 1960–2010 was analyzed and the possible link with anthropogenic aerosols examined. Statistical analysis showed that drizzle and small precipitation has significantly decreased, whereas medium to heavy precipitation has increased slightly over the past 50 years(although not statistically significant). Further data analysis suggested that the decline in drizzle and small precipitation probably has a strong link to increased concentrations of anthropogenic aerosols produced by large-scale human activities related to the rapid socioeconomic development of the PRD region. These aerosols may also have led to the obvious decreasing trend in horizontal visibility and sunshine duration in SC, which is statistically significant according to the t-test. | FU Chuanbo DAN Li | 2014 | Advances in Atmospheric Sciences2014，31，2： | 9 |
| 4 | ^(40)Ar/^(39)Ar geochronology constraints on hydrocarbon accumulation and destruction periods in the Bankeng paleo-reservoir in the southern margin of the middle Yangtze block显示文摘The exact determination of isotopic ages of hydrocarbon accumulation,reconstruction and destruction periods using traditional isotopic dating methods is complex because of the small numbers of minerals that correlate with hydrocarbons.The quantitative and direct study of hydrocarbon geochronology is therefore an important scientific problem for isotope geochronology and petroleum geology.This study obtains two isotopic ages from a quartz vein sample associated with bitumen in a reverse fault located in the Bankeng paleo-reservoir on the southern margin of the middle Yangtze block (the northern margin of the JiangnanXuefeng uplift) by inclusion 40Ar/39Ar stepwise crushing in a vacuum.Two different and good linear inverse isochrons that correspond to two age plateaus were determined.The two ages correspond to primary inclusions of about 228 Ma and secondary inclusions of about 149 Ma.These inclusion groups represent two distinct kinds of fluids.Quartz veins associated with bitumen in faulted paleo-reservoirs,which have a strict response relationship with tectonization and hydrocarbon accumulation,are the unified products of tectonic processes,hydrocarbon accumulation and reconstruction.Therefore,they can be used to constrain the hydrocarbon accumulation,reconstruction and destruction periods that are controlled by multiphase and complicated tectonic actions.The evolutionary processes of hydrocarbon accumulation can be divided into two periods consisting of a primary oil and gas reservoir formation period in the late Indosinian epoch (about 228 Ma) and a period of oil and gas reservoir reconstruction in the early Yanshan epoch (about 149 Ma).This study quantitatively reconstructs the hydrocarbon accumulation and destruction chronological framework of a giant hydrocarbon accumulation belt along the southern margin of the middle Yangtze block (the northern margin of the Jiangnan-Xuefeng uplift) controlled by multiphase and complicated tectonism.The two ages associated with hydrocarbons here correspond to the special controlling actions of continental tectonics in the Jiangnan-Xuefeng uplift that affected the timeline of reconstruction and destruction in this giant marine hydrocarbon accumulation.This study shows the feasibility and usefulness of dating inclusions with the 40Ar/39Ar technique for hydrocarbon geochronology,especially in the marine hydrocarbon accumulation region of southern China within a geological setting of old strata,high thermal evolution hydrocarbons,and complex,multiphase and multicycle tectonization. | LIU ZhaoQian MEI LianFu QIU HuaNing SHEN ChuanBo TANG JiGuang YUN JianBing | 2011 | Chinese Science Bulletin2011，56，26： | 7 |

| 7 | Trends of the sunshine duration and diffuse radiation percentage on sunny days in urban agglomerations of China during 1960–2005显示文摘The long-term observational data of sunshine duration(SD) and diffuse radiation percentage(defined as diffuse solar radiation/total solar radiation, DRP) on sunny days during 1960–2005 were analyzed in 7 urban agglomerations and the whole of China. The results show that the sunny sunshine duration(SSD) has decreased significantly except at a few stations over northwestern China in the past 46 years. An obvious decrease of the SSD is found in eastern China, with the trend coefficients lower than-0.8. Accompanied by the SSD decline, the sunny diffuse radiation percentage(SDRP) in most stations shows obvious increasing trends during the 46 years. The averaged SDRP over China has increased 2.33%per decade, while the averaged SSD shows a decrease of-0.13 hr/day per decade. The correlation coefficient between SDRP and SSD is-0.88. SSD decreased over urban agglomerations(small to large city clusters) in the past 46 years, especially in large cities and medium cities, due to the strong anthropogenic activities and air pollution represented by aerosol option depth(AOD) and tropospheric column NO2(Tro NO2). On the regional scale, SSD has an opposite trend from SDRP during 1960 to 2005, and the variation trends of regional mean values of SSD and SDRP in southeastern China are more pronounced than those in northwestern China. | Chuanbo Fu Li Dan Youlong Chen Jiaxiang Tang | 2015 | Journal of Environmental Sciences2015，27，8： | 5 |
| 8 | Post-Orogenic Tectonic Evolution of the Jiangnan-Xuefeng Orogenic Belt:Insights from Multiple Geochronometric Dating of the Mufushan Massif,South China显示文摘The Mufushan massif, as continental intra-plate magmatites located in the Jiangnan-Xuefeng orogenic belt of the South China. The Mufushan massif constitutes the largest Mesozoic intrusive complex, intruded the Mesoproterozoic Lengjiaxi Formation. Multiple geochronometric dating was used to reconstruct their evolution from emplacement to exhumation. The Mufushan granitoids were emplaced at ~150 Ma(U-Pb zircon) as post-orogenic magmatites contributing to Triassic crustal thickening. Onset of regional extension at ~128 Ma(40Ar/39Ar white mica and biotite) manifests a tectonic regime switch. Intense exhumation prior to ~55 Ma was followed by slow denudation and peneplanation for the next 37 Ma(~55–18 Ma). Accelerated cooling since ~18 Ma may have been caused by a far-field effect of the collision between IndiaAsia Plate or the Pacific-Plate subduction. Through a multi-geochronometric approach, this study provides a new comprehensive model for the cause of the intra-plate magmatism formation in the South China, and also established a reliable geochronological framework of the post-orogenic tectonic evolutions of the Jiangnan-Xuefeng orogenic belt. | Chuanbo Shen Di Hu Kyoungwon Min Chaoqun Yang Xiaowei Zeng Hongyang Fu Xiang Ge | 2020 | Journal of Earth Science2020，31，5： | 4 |

| 13 | Tectonic uplift history of the Yitong Basin since the Oligocene,Northeast China:Evidence from apatite fission track ages and geological relationship显示文摘The Yitong Basin is an oilbearing basin with unique characteristics in Northeast China. On the basis of apatite fission track ages and geological relationship, the tectonic uplift history of the Yitong Basin since the Oligo-cene was discussed. Based on apatite fission track analysis of five samples from the Luxiang and Chaluhe fault depressions and basin modeling study, it can be concluded that since the Oligocene (36.6 Ma) in the Yitong Basin, the Chaluhe fault depression has undergone two episodes of uplift during 24.9-19.1 Ma and 6.9-4.9 Ma. And the Luxiang fault depression also had undergone two episodes of uplift during 30-27.8 Ma and 22.6-11.1 Ma. Moreover, the average apparent exhumation rates for the Chaluhe fault depression and Luxiang fault depression, could be calculated to be 70.34 and 60.33 m/Ma since 21.8 Ma and 18.9 Ma, respectively. The results of thermochronological analysis can also be supported by the evidence from geological relationships such as geodynamics, volcanic activity, and stratigraphic division and correlation. | CAO Qiang YE Jiaren SHEN Chuanbo TANG Daqing | 2010 | Chinese Journal Of Geochemistry2010，29，3： | 3 |
| 14 | Ultrasound-guided fine needle aspiration of retropharyngeal lymph nodes after radiotherapy for nasopharyngeal carcinoma: a novel technique for accurate diagnosis显示文摘Background:Enlarged retropharyngeal lymph nodes(RLNs)are very common in patients with nasopharyngeal carcinoma(NPC)undergoing radiotherapy.The most suitable treatment option for enlarged RLNs depends on the pathological results.However,RLN sampling is difficult and imminent in the clinic setting.We recently developed a novel minimally invasive technique termed endoscopic ultrasound-guided fine needle aspiration(EUS-FNA)for sam-pling RLN tissues sufficient for pathological or cytological diagnosis.Methods:We enrolled 30 post-radiotherapy patients with NPC with suspected RLN metastasis detected via mag-netic resonance imaging(MRI).The EUS probe was introduced into the nasopharynx via the nostrils,and EUS was then used to scan the retropharyngeal space and locate the RLN in the anterior carotid sheath.EUS-FNA was subsequently performed.The safety and efficacy of using EUS-FNA to sample the RLN tissues were assessed.Results:Strips of tissue were successfully sampled from all patients using EUS-FNA.Of the 30 patients,23 were confirmed to have cancer cells in the biopsied tissues via pathology or cytology examinations with 1 EUS-FNA biopsy session.The seven cases without confirmed cancer cells were subsequently reanalyzed by using another EUS-FNA biopsy session,and two more cases were confirmed possessing cancer cells.The other five patients without con-firmed cancer cells were closely followed with MRI every month for 3 months.After follow-up for 3 months,three patients were still considered cancer-free due to the presence of RLNs with stable or shrinking diameters.The rest two patients who showed progressive disease underwent a third EUS-FNA biopsy procedure and were further confirmed to be cancer cell-positive.In the whole cohort reported here,the EUS-FNA procedure was not associated with any severe complications.Conclusion:EUS-FNA is a safe and effective diagnostic approach for sampling tissues from the RLNs in patients with suspected recurrent NPC. | Long-Jun He Chuanbo Xie Yin Li Lin-Na Luo Ke Pan Xiao-Yan Gao Li-Zhi Liu Jian-Ming Gao Guang-Yu Luo Hong-Bo Shan Ming-Yuan Chen Chong Zhao Wei-Jun Fan Ping Yang Guo-Liang Xu Jian-Jun Li | 2018 | Cancer Communications2018，38，1： | 3 |

| 17 | Spatio-temporal enabled urban decision-making process modeling and visualization under the cyber-physical environment显示文摘Urban management is increasingly dependent on the construction of cyber-physical systems, which have been widely deployed in multiple fields, including agriculture, transportation, and health care. Cyberphysical systems provide a large volume of big sensory data. Thus, the application of big data for urban emergency decision-making has become a challenge. Traditional decision-making models are unable to overcome several technical problems, including spatio-temporal information support and access to real-time service for disaster management and emergency response. In this paper, we propose a spatio-temporal enabled urban decision-making process modeling method in the cyber-physical environment and discuss the development off our basic metadata components, the definition of eleven-tuple information description structure. A prototype system is designed for modeling registering, management, visualization, and other functions. Decision-making processes are implemented as composite process chains through three phases, i.e., decision-making process modeling,instantiation of the decision-making process chain and execution of the decision-making process chain. For application to gas leak events, the decision-making process is executed to confirm the feasibility of the proposed decision-making process modeling method and the flexibility of the eleven-tuple information structure. | WANG Wei HU ChuanBo CHEN NengCheng XIAO ChangJiang WANG Chao CHEN ZeQiang | 2015 | Science China(Information Sciences)2015，58，10： | 3 |
| 18 | The Combinatorial Biosynthesis of"Unnatural" Products with Polyketides显示文摘Polyketides have been widely used clinically due to their significant biological activities, but the needed structural and functional diversity cannot be achieved by common chemical synthetic methods. The tool of combinatorial biosynthesis provides the possibility to produce 'unnatural' natural drugs, which has achieved initial success. This paper provides an overview for the strategies of combinatorial biosynthesis in producing the structural and functional diversity of polyketides, including the redesign of metabolic flow, polyketide synthase(PKS) engineering, and PKS post-translational modification. Although encouraging progress has been made in the last decade, challenges still exist regarding the rational combinatorial biosynthesis of polyketides. In this review, the perspectives of polyketide combinatorial biosynthesis are also discussed. | Chuanbo Zhang Di Ke Yuejiao Duan Wenyu Lu | 2018 | Transactions of Tianjin University2018，24，6： | 3 |
| 19 | Model Test of Deformation Evolution and Multi Factor Prediction of Anchorage Slope Stability under Rainfall Condition显示文摘The stability of the anchorage slope on the Baiyang Yangtze River Highway Bridge in Yichang,China,was investigated under different rainfall conditions using model test,numerical simulation,and factor analysis.The results of the study are as follows:(1)with the increase of rainfall intensity,the change of earth pressure can be divided into three stages.However,when the rainfall intensity was larger than a certain value,the change of earth pressure of cut slope became two stages;with the increase of rainfall intensity,pore water pressure increased with the increase of rainfall time,while at a certain stage after the rainfall,the pore water pressure in the cut slope did not decrease immediately,but increased for a period of time.(2)When the rainfall stopped,the stability coefficient of the anchorage slope continued to decrease,then slowly increased,and finally tended to be gentle.Meanwhile,when the rainstorm reached a certain intensity,the main factor that restricted the rainfall infiltration rate became the geotechnical permeability coefficient of the cut slope,which was no longer the rainfall intensity.(3)Factor analysis shows that the rainfall intensity and rainfall duration were the most important factors for anchorage slope stability,while earth pressure,pore water pressure and slope displacement were much less significant. | Tingyao Wu Jianhong Jia Nan Jiang Chuanbo Zhou Xuedong Luo Yuqing Xia | 2020 | Journal of Earth Science2020，31，6： | 3 |
| 20 | Growth and characterization ofβ-Ga_(2)O_(3)thin films grown on off-angled Al_(2)O_(3)substrates by metal-organic chemical vapor deposition显示文摘Beta-gallium oxide(β-Ga_(2)O_(3))thin films were deposited on c-plane(0001)sapphire substrates with different mis-cut angles along<>by metal-organic chemical vapor deposition(MOCVD).The structural properties and surface morphology of as-grownβ-Ga_(2)O_(3)thin films were investigated in detail.It was found that by using thin buffer layer and mis-cut substrate technology,the full width at half maximum(FWHM)of the()diffraction peak of theβ-Ga_(2)O_(3)film is decreased from 2°on c-plane(0001)Al_(2)O_(3)substrate to 0.64°on an 8°off-angled c-plane(0001)Al_(2)O_(3)substrate.The surface root-mean-square(RMS)roughness can also be improved greatly and the value is 1.27 nm for 8°off-angled c-plane(0001)Al_(2)O_(3)substrate.Room temper-ature photoluminescence(PL)was observed,which was attributed to the self-trapped excitons formed by oxygen and gallium vacancies in the film.The ultraviolet-blue PL intensity related with oxygen and gallium vacancies is decreased with the increas-ing mis-cut angle,which is in agreement with the improved crystal quality measured by high resolution X-ray diffraction(HR-XRD).The present results provide a route for growing high qualityβ-Ga_(2)O_(3)film on Al_(2)O_(3)substrate. | Yabao Zhang Jun Zheng Peipei Ma Xueyi Zheng Zhi Liu Yuhua Zuo Chuanbo Li Buwen Cheng | 2022 | Journal of Semiconductors2022，43，9： | 3 |
