1The Interaction of Population,Industry and Land in Process of Urbanization in China:A Case Study in Jilin Province显示文摘Urbanization is a complex process that covers a wide range of topics, of which population, industry and land urbanization are three important aspects. Jilin Province is an important agricultural province in China. The contradiction between population, industry and land urbanization is especially prominent here, and its coupling development is of great practical significance. In this paper, the coupling degree of population-industry-land urbanization in Jilin Province in 1990, 2000 and 2010 is measured by coupling mode. The spatial pattern of the coupling degree is analyzed by trend surface analysis and global and local spatial autocorrelation. The influence factors and their spatial differentiation are discussed using multiple linear regression(MLR) model and geographic weighted regression(GWR) model. The results show that: 1) the coupling degree of population-industry-land urbanization in Jilin Province is at a low level. Judging from the change of time scale, the urbanization of most research units is becoming more and more coordinated. From the comparison of spatial scales, there is significant spatial difference in the research units of different administrative levels. 2) Judging from the global change trend, the coupling degree of population-industry-land urbanization in the central region is higher than that in western and eastern regions. The coordination of urbanization in the central region is relatively good, and the distribution of the cold and hot spots is basically the same as that overall. 3) The spatial pattern of the coupling degree is related to the cold and hot spot distribution of the influence coefficient of urban population density and per capita urban construction land. The variation of the coupling degree spatial pattern is synchronous with the spatial change of the urban population density influence coefficient. 4) The degree of agglomeration of the urban population is the main factor promoting the coupling pattern of population-industry-land urbanization in Jilin Province, and the extent of its influence is gradually increasing. In addition, the level of city administrative, the efficiency of urban expansion and the capacity of market consumption also have an important influence on the coupling pattern.LIU Yanjun ZHOU Guolei LIU Degang YU Huisheng ZHU Liyuan ZHANG Jing 2018Chinese Geographical Science2018,28,3:12
2A meta-analysis of Chinese herbal medicines for vascular dementia显示文摘OBJECTIVE: To investigate the efficacy and safety of Chinese herbal medicines in the treatment of patients with vascular dementia. DATA RETRIEVAL: We retrieved publications from Cochrane Library (2004 to July 2011), PubMed (1966 to July 2011), the Chinese Science and Technique Journals Database (1977 to July 2011), the China National Knowledge Infrastructure (1979 to July 2011), Google Scholar (July 2011), and the Chinese Biomedical Database (1977 to July 2011) using the'Chinese medicine OR Chinese herbal medicine' and 'vascular dementia OR mild cognition impair OR multi-infarct dementia OR small-vessel dementia OR strategic infarct dementia OR hypoperfusion dementia OR hemorrhagic dementia OR hereditary vascular dementia'. SELECTION CRITERIA: Randomized controlled trials comparing Chinese herbal medicines with placebo/western medicine in the treatment of patients with vascular dementia were included. Diagnostic standards included Diagnostic and Statistical Manual of Mental Disorders-IV, and National Institute of Neurological Disorders and Stroke and Association Internationale pour la Recherché et l'Enseignement en Neurosciences. Two participants independently conducted literature screening, quality evaluation and data extraction. The quality of each trial was assessed according to the Cochrane Reviewers' Handbook 5.0. MAIN OUTCOME MEASURES: Effective rate, Mini-Mental State Examination scores, Hasegawa Dementia Scale scores, and incidence of adverse reactions. RESULTS: We identified 1 143 articles discussing the effects of Chinese medicine on vascular dementia. Thirty-one of these were included in the analysis. These studies involved a total of 2 868 participants (1 605 patients took Chinese medicine decoctions (treatment group); 1 263 patients took western medicine or placebo). The results of our meta-analysis revealed that Chinese herbal remedies in the treatment group were more efficacious than the control intervention (relative risk (RR)=1.27; 95% confidence interval (CI): 1.18-1.38, P<0.01). Mini-Mental State Examination scores were higher in patients taking Chinese herbal medicines than in those in the control group (weighted mean difference (WMD)=2.83; 95%CI: 2.55-3.12, P<0.01). Patients in the treatment group showed better disease amelioration than those in the control group (Hasegawa Dementia Scale scores; WMD=2.41, 95%CI: 1.48-3.34, P<0.01). There were also considerably fewer adverse reactions among those in the treatment group compared with those in the control group (RR=0.20, 95%CI: 0.08-0.47, P<0.01). CONCLUSION: Chinese herbal medicine appears to be safer and more effective than control measures in the treatment of vascular dementia. However, the included trials were generally low in quality. More well-designed, high-quality trials are needed to provide better evidence for the assessment of the efficacy and safety of Chinese medicines for vascular dementia.Xiude Qin Yu Liu Yanqing Wu Shuo Wang Dandan Wang Jinqiang Zhu Qiaofeng Ye Wei Mou Liyuan Kang 2013Neural Regeneration Research2013,8,18:7
3Panax notoginseng saponin attenuates hypoxia/reoxygenation-induced oxidative stress in cortical neurons显示文摘The present study monitored the effect of 2, 10, and 50 mg/L of Panax notoginseng saponin exposure following hypoxia-reoxygenation injury in fetal rat cortical neurons. Results showed that varying doses of Panax notoginseng saponin significantly enhanced the cell viability of neurons, reduced malondialdehyde content, increased superoxide dismutase activity, inhibited mRNA and protein expression of inducible and neuronal nitric oxide synthase, and decreased the release of nitric oxide in hypoxia/reoxygenation injured cells. In particular, 50 mg/L of Panax notoginseng saponin was the most effective dose. These findings suggest that Panax notoginseng saponin can attenuate neuronal oxidative stress injury caused by hypoxia/reoxygenation in a dose-dependent manner.Chen Yan Jinqiang Zhu Xiaoxu Jia Chao Wang Shaoxia Wang Liyuan Kang 2012Neural Regeneration Research2012,7,36:7
4Mapping epistasis and environment × QTX interaction based on four-omics genotypes for the detected QTX loci controlling complex traits in tobacco显示文摘Using newly developed methods and software, association mapping was conducted for chromium content and total sugar in tobacco leaf, based on four-omics datasets. Our objective was to collect data on genotype and phenotype for 60 leaf samples at four developmental stages, from three plant architectural positions and for three cultivars that were grown in two locations. Association mapping was conducted to detect genetic variants at quantitative trait SNP(QTS) loci, quantitative trait transcript(QTT) differences,quantitative trait protein(QTP) variability, and quantitative trait metabolite(QTM) changes,which can be summarized as QTX locus variation. The total heritabilities of the four-omics loci for both traits tested were 23.60% for epistasis and 15.26% for treatment interaction.Epistasis and environment × treatment interaction had important impacts on complex traits at all-omics levels. For decreasing chromium content and increasing total sugar in tobacco leaf, six methylated loci can be directly used for marker-assisted selection, and expression of ten QTTs, seven QTPs and six QTMs can be modified by selection or cultivation.Liyuan Zhou Ruiyuan Li Longjiang Fan Yuewei Shi Zhihong Wang Shengdong Xie Yijie Gui Xueliang Ren Jun Zhu 2013The Crop Journal2013,1,2:4
5Hierarchical porous MgBO_2(OH) microspheres: Hydrothermal synthesis,thermal decomposition, and application as adsorbents for Congo red removal显示文摘A facile eco-friendly hydrothermal route(180 °C, 12.0 h) has been developed for the first time to the uniform hierarchical porous MgBO_2(OH) microspheres without the aid of any organic additive, surfactant or template, by using the abundant MgCl_2·6 H_2 O, H_3BO_3 and NaOH as the raw materials. The as-obtained porous microspheres exhibit a specific surface area of 94.752 mg·g^(-1), pore volume of 0.814 cm3·g^(-1), and ca. 84.0% of which have a diameter of 2.25–3.40 μm. The thermal decomposition of the porous MgBO_2(OH) microspheres(650 °C,2.5 °C·min^(-1)) leads to the porous Mg_2B_2O_5 microspheres with well-retained morphology. When utilized as the adsorbents for the removal of CR from mimic waste water, the present porous MgBO_2(OH) microspheres exhibit satisfactory adsorption capacity, with the maximum adsorption capacity q^(-1) mof 309.1 mg·g, much higher than that derived from most of the referenced adsorbents. This opens a new window for the facile green hydrothermal synthesis of the hierarchical porous MgBO_2(OH) microspheres, and extends the potential application of the 3 D hierarchical porous metal borates as high-efficiency adsorbents for organic dyes removal.Panpan Sun Liyuan Chen Lin Xu Wancheng Zhu 2018Chinese Journal of Chemical Engineering2018,26,7:2

7EGFR TKIs impair lysosome-dependent degradation of SQSTM1 to compromise the effectiveness in lung cancer显示文摘Tyrosine kinase inhibitors for epidermal growth factor receptor(EGFR TKIs)greatly improved clinical outcomes of patients with non-small cell lung cancer(NSCLC).Unfortunately,primary and acquired resistance limits their clinical benefits.To overcome such resistance,new generations of EGFR TKIs have been developed by targeting newly identified mutations in EGFR.However,much less effort has been put into alternative strategies,such as targeting the intrinsic protective responses to EGFR TKIs.In this study,we found that EGFR TKIs,including gefitinib and AZD9291,impaired lysosome-dependent degradation of SQSTM1,thus compromising their anti-cancer efficiency.By accumulating in the lysosome lumen,gefitinib and AZD9291 attenuated lysosomal acidification and impaired autolysosomal degradation of SQSTM1 owing to their intrinsic alkalinity.As a result,SQSTM1 protein was stabilized in response to gefitinib and AZD9291 treatment and conferred EGFR TKI resistance.Depleting SQSTM1 significantly increased the sensitivity of NSCLC cells to gefitinib and AZD9291 both in vitro and in vivo.Furthermore,a chemically modified gefitinib analog lacking alkalinity displayed stronger inhibitory effects on NSCLC cells.Therefore,targeting accumulated SQSTM1 or chemically modified EGFR TKIs may represent new strategies to increase the effectiveness of EGFR targeted therapy.Lixian Yang Shilong Ying Shiman Hu Xiangtong Zhao Muchun Li Miaoqin Chen Yiran Zhu Ping Song Liyuan Zhu Tingting Jiang Huimin An Neelum Aziz Yousafzai Wenxia Xu Zhiguo Zhang Xian Wang Lifeng Feng Hongchuan Jin 2019Signal Transduction and Targeted Therapy2019,4,1:2
8Repurposing econazole as a pharmacological autophagy inhibitor to treat pancreatic ductal adenocarcinoma显示文摘Pancreatic ductal adenocarcinoma(PDAC)is characterized by the highest mortality among carcinomas.The pathogenesis of PDAC requires elevated autophagy,inhibition of which using hydroxychloroquine has shown promise.However,current realization is impeded by its suboptimal use and unpredictable toxicity.Attempts to identify novel autophagy-modulating agents from already approved drugs offer a rapid and accessible approach.Here,using a patient-derived organoid model,we performed a comparative analysis of therapeutic responses among various antimalarial/fungal/parasitic/viral agents,through which econazole(ECON),an antifungal compound,emerged as the top candidate.Further testing in cell-line and xenograft models of PDAC validated this activity,which occurred as a direct consequence of dysfunctional autophagy.More specifically,ECON boosted autophagy initiation but blocked lysosome biogenesis.RNA sequencing analysis revealed that this autophagic induction was largely attributed to the altered expression of activation transcription factor 3(ATF3).Increased nuclear import of ATF3 and its transcriptional repression of inhibitor of differentiation-1(ID-1)led to inactivation of the AKT/mammalian target of rapamycin(m TOR)pathway,thus giving rise to autophagosome accumulation in PDAC cells.The magnitude of the increase in autophagosomes was sufficient to elicit ER stress-mediated apoptosis.Furthermore,ECON,as an autophagy inhibitor,exhibited synergistic effects with trametinib on PDAC.This study provides direct preclinical and experimental evidence for the therapeutic efficacy of ECON in PDAC treatment and reveals a mechanism whereby ECON inhibits PDAC growth.Ningna Weng Siyuan Qin Jiayang Liu Xing Huang Jingwen Jiang Li Zhou Zhe Zhang Na Xie Kui Wang Ping Jin Maochao Luo Liyuan Peng Edouard C.Nice Ajay Goel Suxia Han Canhua Huang Qing Zhu 2022Acta Pharmaceutica Sinica B2022,12,7:2

11Recent progress in perovskite solar cells:from device to commercialization显示文摘Perovskite solar cells(PSCs) are undergoing rapid development and the power conversion efficiency reaches 25.7% which attracts increasing attention on their commercialization recently.In this review,we summarized the recent progress of PSCs based on device structures,perovskite-based tandem cells,large-area modules,stability,applications and industrialization.Last,the challenges and perspectives are discussed,aiming at providing a thrust for the commercialization of PSCs in the near future.Xinhui Luo Xuesong Lin Feng Gao Yang Zhao Xiaodong Li Liqing Zhan Zexiong Qiu Jin Wang Cong Chen Lei Meng Xiaofeng Gao Yu Zhang Zijian Huang Rundong Fan Huifen Liu Yanrun Chen Xiaoxue Ren Jiahong Tang Chun-Hao Chen Dong Yang Yongguang Tu Xiao Liu Dongxue Liu Qing Zhao Jingbi You Junfeng Fang Yongzhen Wu Hongwei Han Xiaodan Zhang Dewei Zhao Fuzhi Huang Huanping Zhou Yongbo Yuan Qi Chen Zhaokui Wang Shengzhong(Frank)Liu Rui Zhu Jotaro Nakazaki Yongfang Li Liyuan Han 2022Science China Chemistry2022,65,12:1
12Thermal effects on fracture toughness of cracked straight-through Brazilian disk green sandstone and granite显示文摘Cracked straight-through Brazilian disc(CSTBD) samples prepared using two rock materials were used for thermal treatment from room temperature to 700℃. Uniaxial splitting experiments were performed using an automatic electro-hydraulic servo press to study the evolution laws of physical and fracture properties of different deep rock materials under high-temperature geological conditions. The fracture characteristics were measured using an industrial camera and digital image correlation technology to analyze the effect of high temperature on fracture properties and failure modes of the CSTBD samples after different thermal treatments. The micro-damage properties of green sandstone and granite materials were obtained using a scanning electron microscope(SEM). The following conclusions were drawn from the test results:(1) With the increasing temperature, the fracture characteristics of green sandstone and granite change from brittle fracture to plasticity fracture, the longitudinal wave velocity of granite decreases sharply at 600℃, and the damage factor reaches 0.8748 at 700℃.(2) The fracture toughness of green sandstone and granite decreases with increasing temperature;however, the decreasing range of granite is larger than that of green sandstone.(3) As the temperature increases, the fracture morphologies of green sandstone and granite materials become rougher, whereas thermal damage cracks of granite and intergranular fractures inside sandstone as well as pores of sandstone increase.(4) The crack tip opening displacement and peak strain corresponding to peak load increase with the temperature.Lei Zhou Weiting Gao Liyuan Yu Zheming Zhu Jianxing Chen Xingkai Wang 2022Journal of Rock Mechanics and Geotechnical Engineering2022,14,5:1
13SPECIAL ISSUE: A DISCUSSION ON THE SOURCE OF MEANING OF LITERARY WORKS A Brief Discussion of the Generation of Meaning in Literary Works: A Hermeneutic Examination显示文摘文学作品的意义来源,可以从不同视角考察,诠释学应该是最重要的视角之一。20世纪中期以来,西方诠释学有两个重要理论思潮:一是从海德格尔到伽达默尔的哲学本体论(存在论)诠释学,导向读者中心论的意义观;二是以意大利哲学家贝蒂为代表的“作为精神科学一般方法论的诠释学”,肯定作者(主体)是作品意义重要来源之一。由于复杂的原因,后一种诠释学理论影响较小,伽达默尔的本体论诠释学牢牢占据了欧美学界的主流地位。20世纪90年代以来中国文艺学界同样主要受到从海德格尔、伽达默尔到接受美学的诠释学理论的重大影响,贝蒂的影响几乎可以忽略不计。于是造成读者中心论的文学作品意义观被广泛接受,而把作者赋予作品初始意义的作用淡化甚至否定了。2014年张江提出“强制阐述”论以来,学界开始反思读者中心论的文学作品意义观的片面性(相对主义、主观主义),重新关注作者意义在文学作品意义生成中不可否认的重要性。本文借鉴贝蒂的诠释学思路和方法论,结合文学创作实践,论述文学作品的意义既不是单单由作者赋予的,也不是完全由读者创造的,而是由作者与读者双向互动、共同创造的,是在作者、作品文本和读者三要素动态流程中不断生成的。Zhu Liyuan 2017Social Sciences in China2017,38,4:1

20Bacteroides-derived isovaleric acid enhances mucosal immunity by facilitating intestinal IgA response in broilers显示文摘Background:The interaction between nutrition and immunity plays a vital role in nutrient digestion,absorption,and metabolism during poultry production.Recent studies showed that the gut microbiota contributes to the development of intestinal mucosal immunity.However,the mechanisms by which gut microbes regulate this process remain unclear.Methods:We compared the intestinal mucosal immunity and gut microbiota of Arbor Acre broilers AA(lower mucosal immunity)and Chinese native Wuliang Mountain Black-bone chickens(WLMB)(higher mucosal immunity)using 16S rDNA sequencing,transcriptomic analysis,and immunoglobulin A(IgA)antibody repertoire sequencing.We then combined 16S rDNA sequencing with transcriptomics to identify the key microbes and found that they were positively correlated with IgA production.Next,we transplanted candidate microbes into 1-day-old broiler to explore their role in intestinal mucosal immunity.Finally,we verified the function of candidate microbial metabolites in regulating the immune function of macrophages and the intestinal-epithelial cells(IECs)using in vitro experiments.Results:WLMB performs stronger mucosal immunity than AA,including higher IgA levels,more diverse IgA antibody repertoire,and higher bacterial affinity.Bacteroides was identified as the key microbes related to the intestinal IgA response.Bacteroides transplantation could increase IgA concentration in the duodenal contents by enhancing the expression of IgA,polymeric immunoglobin receptor(PIgR),B cell-activating factor of the TNF family(BAFF),and activation-induced cytidine deaminase(AID)in the duodenum.Additionally,Bacteroides-derived isovaleric acid promoted M2 macrophage polarization of macrophage via mTOR/PPAR-γ/STAT3 signaling pathways and regulated the immunologic function of IECs to produce cytokines,including interleukin(IL)-10,IL-4,BAFF,and transforming growth factor-beta(TGF-β),thus promoting IgA production in B cells by facilitating AID expression.Conclusion:Our study revealed that Bacteroides modulate the intestinal IgA response and maintain gut health in broilers.Bacteroides may be a promising alternative as an immunomodulatory microbial agent for developing nextgeneration probiotics for broiler production.Xinkai Wang Yifan Hu Xiaoyan Zhu Liyuan Cai Muhammad Zahid Farooq Xianghua Yan 2023Journal of Animal Science and Biotechnology2023,14,3:1
