| 1 | 区域旅游流空间结构的高铁效应及机理--以中国京沪高铁为例显示文摘交通是影响旅游流空间结构最主要因素之一。以京沪高铁线为例,探讨了区域旅游流空间结构的高铁效应及特征,在此基础上,分析区域交通可达性变化,并结合区域旅游资源禀赋、区域旅游接待设施、区域旅游交通网络密度以及区位等影响因素分析区域旅游流空间结构的高铁效应的机理。研究表明:1区域旅游流空间结构的高铁效应表现为马太效应、过滤效应、扩散效应和叠加效应等特征。2区位条件、旅游资源禀赋、旅游接待能力、交通网络密度以及时空压缩程度等影响因素共同作用均非常明显态势下,产生高铁马太效应;旅游资源禀赋、旅游接待能力、交通网络密度均不强,时空压缩程度不显著等旅游节点产生高铁过滤效应;区位条件、旅游资源禀赋、旅游接待能力和交通网络密度均具有很强优势,且时空压缩程度明显等旅游节点可成为扩散源,高铁强化了扩散源旅游流集聚作用,然后向边缘旅游地扩散,呈现为'集聚—扩散'模式;高铁使大尺度空间的不同客源地居民出游空间范围出现叠加现象,但只有区位条件、旅游资源禀赋、旅游接待能力、交通网络密度优势较强且时空压缩程度明显旅游节点产生叠加效应。 | 汪德根 陈田 陆林 王莉 ALAN August Lew | 2015 | 地理学报2015，70，2： | 226 |
| 2 | The PI3K/Akt/m TOR pathway in ovarian cancer: therapeutic opportunities and challenges显示文摘The phosphatidylinositol 3 kinase(PI3K) pathway is frequently altered in cancer, including ovarian cancer(OC). Unfortunately, despite a sound biological rationale and encouraging activity in preclinical models, trials of first-generation inhibitors of mammalian target of rapamycin(m TOR) in OC have demonstrated negative results. The lack of patient selection as well as resistance to selective m TOR complex-1(m TORC1) inhibitors could explain the disappointing results thus far. Nonetheless, a number of novel agents are being investigated, including dual m TORC1/m TORC2, Akt, and PI3 K inhibitors. Although it is likely that inhibition of the PI3K/Akt/m TOR pathway may have little effect in unselected OC patients, certain histological types, such as clear cell or endometrioid OC with frequent phosphatidylinositol-4,5-biphosphate 3-kinase, catalytic subunit alpha(PIK3CA) and/or phosphatase and tensin homolog(PTEN) alterations, may be particularly suited to this approach. Given the complexity and redundancy of the PI3 K signaling network, PI3 K pathway inhibition may be most useful in combination with either chemotherapy or other targeted therapies, such as MEK inhibitors, anti-angiogenic therapy, and hormonal therapy, in appropriately selected OC patients. Here, we discuss the relevance of the PI3 K pathway in OC and provide an up-to-date review of clinical trials of novel PI3 K inhibitors alone or in combination with cytotoxics and novel therapies in OC. In addition, the challenges of drug resistance and predictive biomarkers are addressed. | Bianca Cheaib Aurélie Auguste Alexandra Leary | 2015 | Chinese Journal of Cancer2015，34，1： | 27 |

| 4 | 尺度、变化和恢复力:社区旅游规划的视角显示文摘近年来,恢复力规划逐渐作为可持续发展的一种替代范式,为快速变化中的社区发展和社会-生态转型提供了新的视角。社区恢复力这个新兴概念在很多学科已有所涉猎,旅游学者也从某种程度上逐渐接受这一理念。但大多数关于社区恢复力的研究主要关注的是重大灾难和危机等突发事件,鲜有对渐变事件和过程进行研究。因此,建立一个包含缓慢变量的新框架将进一步拓展恢复力相关研究。论文中建立的旅游恢复力模型包含了从慢到快的变化速率以及从业主到社区旅游收益的不同尺度,并得出一个2×2矩阵,该矩阵中呈现了4种相互区别的恢复力主题、方法和测度,涵盖了从企业家维护日常管理的需求到社区灾难的应急、响应和恢复等诸多方面。作者进而通过对台湾乡村旅游的研究,修订了SCR模型,建立了应对扰动和变化的社区尺度、变化和恢复力系统及子系统推广模型。新的模型改变尺度、变化和恢复力的通用模型,具有等级体系,包含一个系统和至少一个子系统,并以阈值线来界定区分变化程度。另外,对SCR模型的四个象限进行了正式的命名,即管理、资源、规划、治理恢复力/可持续性。 | Alan August Lew 何景明 高彬 | 2016 | 资源科学2016，38，9： | 9 |
| 5 | Operative complications and economic outcomes of cholecystectomy for acute cholecystitis显示文摘BACKGROUND Recent management of acute cholecystitis favors same admission(SA)or emergent cholecystectomy based on overall shorter hospital stay and therefore cost savings.We adopted the practice of SA cholecystectomy for the treatment of acute cholecystitis at our tertiary care center and wanted to evaluate the economic benefit of this practice.We hypothesized that the existence of complications,particularly among patients with a higher degree of disease severity,during SA cholecystectomy could negate the cost savings.AIM To compare complication rates and hospital costs between SA vs delayed cholecystectomy among patients admitted emergently for acute cholecystitis.METHODS Under an IRB-approved protocol,complications and charges for were obtained for SA,later after conservative management(Delayed),or elective cholecystectomies over an 8.5-year period.Patients were identified using the acute care surgery registry and billing database.Data was retrieved via EMR,operative logs,and Revenue Cycle Operations.The severity of acute cholecystitis was graded according to the Tokyo Guidelines.TG18 categorizes acute cholecystitis by Grades 1,2,and 3 representing mild,moderate,and severe,respectively.Comparisons were analyzed withχ2,Fisher’s exact test,ANOVA,ttests,and logistic regression;significance was set at P<0.05.RESULTS Four hundred eighty-six(87.7%)underwent a SA while 68 patients(12.3%)received Delayed cholecystectomy.Complication rates were increased after SA compared to Delayed cholecystectomy(18.5%vs 4.4%,P=0.004).The complication rates of patients undergoing delayed cholecystectomy was similar to the rate for elective cholecystectomy(7.4%,P=0.35).Mortality rates were 0.6%vs 0%for SA vs Delayed.Patients with moderate disease(Tokyo 2)suffered more complications among SA while none who were delayed experienced a complication(16.1%vs 0.0%,P<0.001).Total hospital charges for SA cholecystectomy were increased compared to a Delayed approach($44500±$59000 vs$35300±$16700,P=0.019).The relative risk of developing a complication was 4.2x[95%confidence interval(CI):1.4-12.9]in the SA vs Delayed groups.Among eight patients(95%CI:5.0-12.3)with acute cholecystitis undergoing SA cholecystectomy,one patient will suffer a complication.CONCLUSION Patients with Tokyo Grade 2 acute cholecystitis had more complications and increased hospital charges when undergoing SA cholecystectomy.This data supports a selective approach to SA cholecystectomy for acute cholecystitis. | Christopher P Rice Krishnamurthy B Vaishnavi Celia Chao Daniel Jupiter August B Schaeffer Whitney R Jenson Lance W Griffin William J Mileski | 2019 | World Journal of Gastroenterology2019，25，48： | 8 |
| 6 | 区域旅游流空间结构的高铁效应及机理(英文)显示文摘Chinese railway has entered the 'HSR era', while the structure of 'four vertical and four horizontal' railways for transit passengers is almost completed. Taking the Beijing-Shanghai High-Speed Rail(hereinafter referred to as HSR) as an example, this paper first explores HSR's effects on the spatial structure of regional tourist flows using the social network analysis. Next, it notes changes in the accessibility of regional transportation. After analyzing the factors including initial endowment of regional tourism resources, hospitality facilities, the density of the regional tourism transportation network, and locations, the paper discusses the mechanisms through which HSR affects regional tourist flows. The study shows the following:(1) HSR's effects on the spatial structure of regional tourist flows are manifested through the Matthew effect, the filtering effect, the diffusion effect and the overlying effect, and(2) the Matthew effect of HSR is manifested under an obvious interaction of the location, the initial endowment of tourism resources, hospitality capacity, tourist transportation network density and 'time-space compression'. The filtering effect of HSR is manifested for those tourism nodes without favorable location conditions, endowment of tourism resources, hospitality capacity, or tourist transportation network density and without obvious benefits from 'time-space compression'. Those tourism nodes that boast advantages in terms of location condition, endowment of tourism resources, hospitality capacity, tourist transportation network density and obvious 'time-space compression' will become sources for the diffusion effect. HSR will strengthen the aggregation effects of tourist flow in these diffusion sources, which will thereafter diffuse to peripheral tourist areas, manifesting 'aggregation-diffusion'. HSR has overlapped tourists' spatial traveling range over large-scale spaces. However, the overlying effect is only generated in those tourism nodes with a favorable location condition, an endowment of tourism resources, hospitality capacity, tourist transportation network density, and obvious 'time-space compression'. | 汪德根 王莉 陈田 陆林 牛玉 ALAN August Lew | 2016 | Journal of Geographical Sciences2016，26，12： | 7 |

| 9 | APPLICABILITY OF THE MASS ACTION LAW IN COMBINATION WITH THE COEXISTENCE THEORY OF METALLIC MELTS INVOLVING COMPOUND TO BINARY METALLIC MELTS显示文摘Based on the atomicity and molecularity as well as the consistency of thermodynamicproperties and activities of metallic melts with their structures, the coexistence the-ory of metallic melts structure involving compound has been suggested. According tothis theory, the calculating models of mass action concentrations for different binarymetallic melts have been formulated. The calculated mass action concentrations agreewell with corresponding measured activities, which confirms that the suggested theorycan reflect the structural characteristics of metallic melts involving compound and thatthe mass action law is widely applicable to this kind of metallic melts. | J.ZhangMetallurgical Engineering School, University of Science and Technology Beijing, Beijing 100083, China Manuscript received 9 March 2001 in revised form 7 August 2001 | 2002 | Acta Metallurgica Sinica(English Letters)2002，15，4： | 4 |
| 10 | The research on the adsorption effect on metal ions by immobilized marine algae显示文摘The process of adsorption of Cu2+, Cd2+ by immobilized marine algae was investigated. It can be noted from the results that, the process for biosorption of heavy metals (copper, cadmium) by immobilized Laminaria japonica can be described by the Banerm model. According to the model, the adsorption rate constant calculated was 0.107 8 and 0.030 28 min-1 for Cu2+ and Cd2+ respectively. The experimental biosorption equilibrium data for Cu2+ and Cd2+ were in good agreement with those calculated by the Langmuir model. The maximum uptake capacity calculated was 83.3 and 112.4 mg/g for Cu2+ and Cd2+ according to the Langmuir model, respectively. The appetency of Laminaria japonica to Cu2+ was better than Cd2+. | WANG Xian1*, QIU Haiyuan1, CAI Zhenzhen1, CHEN Lidan1, ZHENG Shenghua1, HUANG Zhiwei11.

| 12 | MD simulation of the effect of contact area and tip radius on nanoindentation显示文摘Molecular dynamics simulations of nanoindentation are performed on monocrystal copper. A new contact atoms method is presented for calculating the contact area. Compared with conventional methods, this method can provide the contact area more accurately not only for sink-in but also for pile-up situation. The effect of tip radius on indentation is investigated too. The results indicate that the measured hardness of the material will become higher as the tip radius increases. | CHEN Shangda1,2 & KE Fujiu1,2 1.

| 13 | Stem cell autotomy and niche interaction in different systems显示文摘The best known cases of cell autotomy are the formation of erythrocytes and thrombocytes(platelets) from progenitor cells that reside in special niches. Recently, autotomy of stem cells and its enigmatic interaction with the niche has been reported from male germline stem cells(GSCs) in several insect species. First described in lepidopterans, the silkmoth, followed by the gipsy moth and consecutively in hemipterans, foremost the milkweed bug. In both, moths and the milkweed bug, GSCs form finger-like projections toward the niche, the apical cells(homologs of the hub cells in Drosophila). Whereas in the milkweed bug the projection terminals remain at the surface of the niche cells, in the gipsy moth they protrude deeply into the singular niche cell. In both cases, the projections undergo serial retrograde fragmentation with progressing signs of autophagy. In the gipsy moth, the autotomized vesicles are phagocytized and digested by the niche cell. In the milkweed bug the autotomized vesicles accumulate at the niche surface and disintegrate. Autotomy and sprouting of new projections appears to occur continuously. The significance of the GSC-niche interactions, however, remains enigmatic. Our concept on the signaling relationship between stem cell-niche in general and GSC and niche(hub cells and cyst stem cells) in particular has been greatly shaped by Drosophila melanogaster. In comparing the interactions of GSCs with their niche in Drosophila with those in species exhibiting GSC autotomy it is obvious that additional or alternative modes of stem cell-niche communication exist. Thus, essential signaling pathways, including niche-stem cell adhesion(E-cadherin) and the direction of asymmetrical GSC division- as they were found in Drosophila- can hardly be translated into the systems where GSC autotomywas reported. It is shown here that the serial autotomy of GSC projections shows remarkable similarities with Wallerian axonal destruction, developmental axon pruning and dying-back degeneration in neurodegenerative diseases. Especially the hypothesis of an existing evolutionary conserved 'autodestruction program' in axons that might also be active in GSC projections appears attractive. Investigations on the underlying signaling pathways have to be carried out. There are two other well known cases of programmed cell autotomy: the enucleation of erythroblasts in the process of erythrocyte maturation and the segregation of thousands of thrombocytes(platelets) from one megakaryocyte. Both progenitor cell types- erythroblasts and megakaryocytes- are associated with a niche in the bone marrow, erythroblasts with a macrophage, which they surround, and the megakaryocytes with the endothelial cells of sinusoids and their extracellular matrix. Although the regulatory mechanisms may be specific in each case, there is one aspect that connects all described processes of programmed cell autotomy and neuronal autodestruction: apoptotic pathways play always a prominent role. Studies on the role of male GSC autotomy in stem cell-niche interaction have just started but are expected to reveal hitherto unknown ways of signal exchange. Spermatogenesis in mammals advance our understanding of insect spermatogenesis. Mammal and insect spermatogenesis share some broad principles, but a comparison of the signaling pathways is difficult. We have intimate knowledge from Drosophila, but of almost no other insect, and we have only limited knowledge from mammals. The discovery of stem cell autotomy as part of the interaction with the niche promises new general insights into the complicated stem cell-niche interdependence. | David C Dorn August Dorn | 2015 | World Journal of Stem Cells2015，7，6： | 3 |
| 14 | Compound screening platform using human induced pluripotent stem cells to identify small molecules that promote chondrogenesis显示文摘Articular cartilage,which is mainly composed of collagen Ⅱ,enables smooth skeletal movement.Degeneration of collagen Ⅱ can be caused by various events,such as injury,but degeneration especially increases over the course of normal aging.Unfortunately,the body does not fully repair itself from this type of degeneration,resulting in impaired movement.Microfracture,an articular cartilage repair surgical technique,has been commonly used in the clinic to induce the repair of tissue at damage sites.Mesenchymal stem cells(MSC)have also been used as cell therapy to repair degenerated cartilage.However,the therapeutic outcomes of all these techniques vary in different patients depending on their age,health,lesion size and the extent of damage to the cartilage.The repairing tissues either form fibrocartilage or go into a hypertrophic stage,both of which do not reproduce the equivalent functionality of endogenous hyaline cartilage.One of the reasons for this is inefficient chondrogenesis by endogenous and exogenous MSC.Drugs that promote chondrogenesis could be used to induce self-repair of damaged cartilage as a non-invasive approach alone,or combined with other techniques to greatly assist the therapeutic outcomes.The recent development of human induced pluripotent stem cell(iPSCs),which are able to self-renew and differentiate into multiple cell types,provides a potentially valuable cell resource for drug screening in a“more relevant”cell type.Here we report a screening platform using human iPSCs in a multi-well plate format to identify compounds that could promote chondrogenesis. | Sheng-Lian Yang Erica Harnish Thomas Leeuw Uwe Dietz Erika Batchelder Paul SWright Jane Peppard Paul August Cecile Volle-Challier Francoise Bono Jean-Marc Herbert Juan Carlos Izpisua Belmonte | 2012 | Protein & Cell2012，3，12： | 3 |

| 16 | Viral hepatitis:Past,present,and future显示文摘Each hepatitis virus—Hepatitis A,B,C,D,E,and G—poses a distinct scenario to the patient and clinician alike.Since the discovery of each virus,extensive knowledge regarding epidemiology,virologic properties,and the natural clinical and immunologic history of acute and chronic infections has been generated.Basic discoveries about host immunologic responses to acute and chronic viral infections,combined with virologic data,has led to vaccines to prevent Hepatitis A,B,and E and highly efficacious antivirals for Hepatitis B and C.These therapeutic breakthroughs are transforming the fields of hepatology,transplant medicine in general,and public and global health.Most notably,there is even an ambitious global effort to eliminate chronic viral hepatitis within the next decade.While attainable,there are many barriers to this goal that are being actively investigated in basic and clinical labs on the local,national,and international scales.Herein,we discuss pertinent clinical information and recent organizational guidelines for each of the individual hepatitis viruses while also synthesizing this information with the latest research to focus on exciting future directions for each virus. | Matthew August Odenwald Sonali Paul | 2022 | World Journal of Gastroenterology2022，28，14： | 3 |
| 17 | Biliary leakage after urgent cholecystectomy: Optimization of endoscopic treatment显示文摘AIM: To investigate the results of endoscopic treatment of postoperative biliary leakage occurring after urgent cholecystectomy with a long-term follow-up.METHODS: This is an observational database study conducted in a tertiary care center. All consecutive patients who underwent endoscopic retrograde cholangiography(ERC) for presumed postoperative biliary leakage after urgent cholecystectomy in the period between April 2008 and April 2013 were considered for this study. Patients with bile duct transection and biliary strictures were excluded. Biliary leakage was suspected in the case of bile appearance from either percutaneous drainage of abdominal collection or abdominal drain placed at the time of cholecystectomy. Procedural and main clinical characteristics of all consecutive patients with postoperative biliary leakage after urgent cholecystectomy, such as indication for cholecystectomy, etiology and type of leakage, ERC findings and post-ERC complications, were collected from our electronic database. All patients in whom the leakage was successfully treated endoscopically were followed-up after they were discharged from the hospital and the main clinical characteristics, laboratory data and common bile duct diameter were electronically recorded. RESULTS: During a five-year period, biliary leakage was recognized in 2.2% of patients who underwent urgent cholecystectomy. The median time from cholecystectomy to ERC was 6 d(interquartile range, 4-11 d). Endoscopic interventions to manage biliary leakage included biliary stent insertion with or without biliary sphincterotomy. In 23(77%) patients after first endoscopic treatment bile flow through existing surgical drain ceased within 11 d following biliary therapeutic endoscopy(median, 4 d; interquartile range, 2-8 d). In those patients repeat ERC was not performed andthe biliary stent was removed on gastroscopy. In seven(23%) patients repeat ERC was done within one to fourth week after their first ERC, depending on the extent of the biliary leakage. In two of those patients common bile duct stone was recognized and removed. Three of those seven patients had more complicated clinical course and they were referred to surgery and were excluded from long-term follow-up. The median interval from endoscopic placement of biliary stent to demonstration of resolution of bile leakage for ERC treated patients was 32 d(interquartile range, 28-43 d). Among the patients included in the follow-up(median 30.5 mo, range 7-59 mo), four patients(14.8%) died of severe underlying comorbid illnesses.CONCLUSION: Our results demonstrate the great efficiency of the endoscopic therapy in the treatment of the patients with biliary leakage after urgent cholecystectomy. | Neven Ljubii Alen Bianin Tajana Pavi Marko Nikoli Ivan Budimir August Miji Ana Duzel | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，5： | 3 |
| 18 | Controlled Radical Polymerization of Styrene in the Presence of Different Copper Complexes and Organic Halides显示文摘The polymerization behaviors of Styrene (St) in the presence of CuX/L [X=Cl or Br; L= 2,2 bipyridine (bpy), 1,10 phenanthroline (phen) or 4,7 diphenyl 1,10 phenanthroline (DPP) ] and R X (R=trichloromethyl, benzyl or allyl; X=Cl or Br) have been studied and examined. In a CuCl/bpy/RCl/St system, a bimodal GPC peak at the early stage of polymerization was observed, and a concept of multi active species was proposed to explain this phenomenon. In a CuCl/phen (DPP)/RCl/St system, the \%M\%\-n of polystyrene (PS) increased linearly with St conversion and ln[M] o/[M] also increased linearly with time, indicating the living nature of this system. Furthermore, the stability of the propagating active species in a CuBr/phen/RBr/St system is higher than that in the CuBr/phen/RBr/St system. | CHENG Guang lou, HU Chun pu \{**\} and YING Sheng kang (Laboratory of Living Polymerization, East China University of Science and Technology, Shanghai 200237, P.R.
