Dual Land Market and Rapid China’s Urbanization: Problems and Solutions  [PDF]
Huachun Wang, Chunxue Zhao, Maerhaba Xiaokaiti, Yue Zhou, Rui Zhao
Chinese Studies (ChnStd) , 2012, DOI: 10.4236/chnstd.2012.11001
Abstract: The dual land market has greatly encouraged the economy and urban development and created far-reaching effects on excessive land expropriation and land finance. Using an analytical framework of dual market structure model, this paper investigates the relationship between local land finance and China’s rapid urbanization. Low-cost land expropriation is the main reason why extensive urbanization goes so fast in recent China. Granting farmers the complete land rights, implementing property tax to consolidate local tax bases, unifying the dual land market are helpful to achieve both social equity and land use efficiency in Chinese rapid urbanization process.

Xiaocong Fang, Chunxue Bai, Xiangdong Wang
Clinical and Translational Medicine , 2012, DOI: 10.1186/2001-1326-1-9
Abstract: In recent years, there is a great increase in genomics and other molecular research which produced a tremendous amount of information related to molecular biology [1-3]. Meantime, various powerful data mining and statistical bioinformatics methods have been propagated for identifying, prioritizing and classifying robust and generalizable biomarkers with high discriminatory ability [4], and some online bioinformatics data libraries, such as Enzyme, KEGG, Gene Ontology, NCBI Taxonomy, SwissProt and TrEMBL were generated for the store and management of data. Bioinformatics now entails the creation and advancement of databases, algorithms, computational and statistical techniques and theory to solve formal and practical problems arising from the management and analysis of biological data.Clinical bioinformatics is a new emerging science combining clinical information, (including patients’ complaints, history, clinical symptoms and signs, physicians’ examinations, biochemical analysis, imaging profiles, pathologies), omics science, mathematics, information technology and library data together. It may play a potentially important role in the discovery of biomarkers, which will facilitate the diagnosis of disease, as well as treatment. A commonly used definition of a biomarker is “a characteristic that is objectively measured and evaluated as an indicator of normal biological process, pathogenic processes, or pharmacologic responses to a therapeutic intervention” [5]. Clinical bioinformatics is also a new way to focus on the combination of clinical symptoms and signs with human tissue-generated bioinformatics to get deep and full understand of the risk factors, pathogenesis and progress of human disease. Recent technological developments in genomics, proteomics, metabolomics, are allowing researchers to take an unbiased ‘big-picture’ approach to further elucidate the molecular pathogenesis of lung injury [6] (Figure 1). Recent years, clinical bioinformatics have been widel
Characteristics of Chinese patients with cough in primary care centre
Qunying Hong, Chunxue Bai, Xiangdong Wang
Journal of Translational Medicine , 2011, DOI: 10.1186/1479-5876-9-149
Abstract: Approximately 18,000 subjects recruited were having daytime or night symptoms of cough and diagnoses of respiratory disease from February 2005 to April 2006 as Survey 1 and from June 2007 to December 2007 as Survey 2. Patients suffering from respiratory malignancy, hyperthyroidism, hypertension, heart disease, diabetes, severe hypohepatia or renal dysfunction, pregnancy, possible pregnancy or lactation, neutropenia were not eligible. Information regarding demography, history of allergies, symptomatic profile, treatment and curative effects for cough was elicited.8216 questionnaires were collected in Survey 1 and 9711 in Survey 2. The mean values of ages were 25.7 and 22.3 years old, respectively. Symptoms included expectoration (74% and 76%), wheeze (59% and 74%), breathlessness (22% and 26%), chest pain (9% and 13%) and fever (15% and 18%). About 15% and 23% patients had hypersusceptibility, of whom 6% to 17% had a family history. More than 50% of the cases had histories of allergic rhinitis, asthma, conjunctivitis or atopic dermatitis. Asthma, COPD, and bronchitis were dominant etiologies of cough. Procaterol or the combination of antibiotics and steroids were used as the treatment.Causes and outcomes of cough differed with ages and time in this particular national study, while successful and precise diagnosis and management of cough in primary care settings need to be further improved in China.Cough is one of the most common respiratory symptoms encountered by clinicians [1], with the reported prevalence varying between 5% and 40% [2-4]. Cough is also one of the critical factors affecting the quality of life in patients with respiratory diseases. Cough management has massive economic consequences. The first guideline on the management of cough with a significant positive impact was championed in 1998 [5], followed by the publication of other guidelines on chronic cough [6-9]. The Chinese Medical Association published "Diagnosis and treatment guide (draft) of coug

World Journal of Neuroscience (WJNS) , 2015, DOI: 10.4236/wjns.2015.51004
Abstract: Aim:To explore what is the relationship of the types of post-stroke aphasia with sex, age andstroke types.Methods:Retrospective analysis was administrated on data of 421 patients with acutestroke. Western battery aphasia was used to measure aphasiac type and aphasia quotient (AQ)score. The patients were divided into three age groups: young, middle-aged and elderly. The stroketypes were classified into cerebral infraction (CI) and intracerebral hemorrhage (ICH). Results: All subjects were right-handed, which males and females accounted for 69.60% and 30.40%, respectively. There were 116 cases of Broca’s aphasia (85 males), 35 cases of Wernicke’s aphasia (20 males),15 cases of conductive aphasia (10 males), 63 cases of transcortical motor aphasia (50 males), 11 cases of transcortical sensory aphasia (8 males), 27 cases of transcortical combined aphasia (13 males), 73 cases of anomic aphasia (47 males) and 81 cases of global aphasia (60 males). Male patients (69.60%) have a significantly higher morbidity of aphasia than that of females (30.40%) after stroke (χ2

Genetic Vaccines and Therapy , 2010, DOI: 10.1186/1479-0556-8-2
Abstract: Background Allergen-induced imbalance of specific T regulatory (Treg) cells and T helper 2 cells plays a decisive role in the development of immune response against allergens. Objective To evaluate effects and potential mechanisms of DNA vaccine containing ovalbumin (OVA) and Fc fusion on allergic airway inflammation. Methods Bronchoalveolar lavage (BAL) levels of inflammatory mediators and leukocyte infiltration, expression of CD11c+CD80+ and CD11c+CD86+ co-stimulatory molecules in spleen dendritic cells (DCs), circulating CD4+ and CD8+ T cells, Foxp3+ in spleen CD4+ T cells and spleen CD4+ T cells were measured in OVA-sensitized and challenged animals pretreated with pcDNA, OVA-pcDNA, Fc-pcDNA, and OVA-Fc-pcDNA. Results OVA-Sensitized and challenged mice developed airway inflammation and Th2 responses, and decreased the proliferation of peripheral CD4+and CD8+ T cells and the number of spleen Foxp3+ Treg. Those changes with increased INF-γ production and reduced OVA-specific IgE production were protected by the pretreatment with OVA-Fc-pcDNA. Conclusion DNA vaccine encoding both Fc and OVA showed more effective than DNA vaccine encoding Fc or OVA alone, through the balance of DCs and Treg.
Archaeological study of ostrich eggshell beads collected from SDG site
ChunXue Wang,Yue Zhang,Xing Gao,XiaoLing Zhang,HuiMin Wang
Chinese Science Bulletin , 2009, DOI: 10.1007/s11434-009-0620-6
Abstract: Ostrich eggshell beads and fragments collected from SDG site reflect primordial art and a kind of symbolic behavior of modern humans. Based on stratigraphic data and OSL dating, these ostrich eggshell beads are probably in Early Holocene (< 10 ka BP). Two different prehistoric manufacturing pathways are usually used in the manufacture of ostrich eggshell beads in Upper Paleolithic. According to statistic analysis of the characteristics of ostrich eggshell beads, Pathway 1 is identified from these collections. In pathway 1, blanks are drilled prior to being trimmed to rough discs. They exhibit great potential for the study of the origin of primordial art and the development of ancient cultures and provide important data for studying behavioral options adopted by hominids in SDG area. In addition, they bear important implications for the origin of modern humans in East Asia.

Yue Zhang,ChunXue Wang,ShuangQuan Zhang,Xing Gao
Chinese Science Bulletin , 2009, DOI: 10.1007/s11434-009-0616-2
Abstract: In this paper, cut marks on the long bones of class II sized animals in the Ma’anshann site are studied. Based on the location and frequencies of the long bone cut marks, the distribution characteristics are analyzed as follows: (1) cut mark frequencies in the lower layer (LL) are much higher than those of the upper; (2) in the LL cut mark frequency of the upper limbs is the highest, and that of the middle and lower limbs is lower and the lowest; (3) In the upper layer (UL) the cut mark frequency, does not spread as orderly as in the LL. The data are compared to those of the experiment and it is demonstrated that values of the LL all fall into the experimental 95% confidence intervals, and the cut mark frequencies of the upper, middle and lower limbs coincide with those of the experiment; while the values of the UL are much lower, of which, those of the humerus, femur and radius are out of the intervals, and the frequencies of the upper, middle and lower limbs are far more different from those of the experiment. It implies that the earlier hominids (of the LL) defleshed the limbs of the class II sized animals with stone tools more completely than the later hominids. With the evidence of burning marks, it is suggested that the difference on the roasting behaviors derived the cut mark difference of the Ma’anshan UL and LL.
Use-wear evidence confirms the earliest hafted chipped-stone adzes of Upper Palaeolithic in northern China

Chinese Science Bulletin , 2010, DOI: 10.1007/s11434-009-0566-8
Abstract: Chipped-stone “adze-shaped objects” (ASOs) were identified from a few Upper Palaeolithic sites in northern China. Its morphological form resembles to ground-stone type-specific adze, but the function of the ASO has never been assessed. The objective of this study is to investigate the use function of this particular tool type recovered from the Hutouliang site in the Nihewan Basin of northern China. In this study, the lithic use-wear analysis is applied to examining microscopically edge-damages and surface-rounding of the tools in order to assess how they were employed. The result suggests that the ASO might have been used as woodworking tools with a hafted shaft, providing evidence for the appearance of the earliest hafted chipped-stone adzes prior to 10000 years ago in northern China. This study also demonstrates that the use-wear technique is an innovated and effective analytic appraoch to the study of stone tool functions that has been conventionally treated by typo-technological analyses. Stone tool use-patterns revealed by use-wear evidence would shed new insights on prehistoric adaptive strategies of modern human in northern China.
Heat treatment and associated early modern human behaviors in the Late Paleolithic at the Shuidonggou site
ZhenYu Zhou,Ying Guan,Xing Gao,ChunXue Wang
Chinese Science Bulletin , 2013, DOI: 10.1007/s11434-012-5522-3
Abstract: Unearthed artifacts and cultural relics from the Shuidonggou site revealed extensive information and insights regarding the activities of early modern humans. A series of experimental research and physical analysis suggest that stone artifacts from Locality 2 and Locality 12 have undergone heat treatment. The utilization ratio and knapping properties of raw materials were consequently enhanced. Heat treatment technology reflects the production capacities and the survival strategies in the Upper Paleolithic period. This discovery indicates the earliest existence of this technology in the East Asia and thus confirms a wider geographic distribution of this technology which provides new perspectives and evidence for understanding the associated early modern human behaviors.

Abstract: By using the snow cover days data from the meteorology stations in China, the NCEP/NCAR reanalysis data, and the Multi Taper Method-Singular Value Decomposition (MTM-SVD), the spatial and temporal variation of the summer precipitation in recent 50 years in the Yellow River basin and its impact factors are analyzed. The prominent period of the summer precipitation is 2-3 years. There is a response of the summer precipitation in the Yellow River basin to the previous winter snow cover days over the Tibetan Plateau with a quasi-three-year period. When the previous winter snow cover days over the Tibetan Plateau is abnormally more (less), there is abnormally less (more) precipitation in the next summer in the Yellow River basin. This response has decadal variation, the most significant period appears before 1983 and there is an adjustment stage between 1983 and 1993, which again appears significantly after 1993. And there is a response of the summer precipitation in the Yellow River basin to the previous winter SST over the western Pacific warm pool with a quasi-two-year period. When the previous winter SST over the western Pacific warm pool is abnormally high (low), there is abnormally more (less) precipitation in the next summer in eastern Yellow River basin. This response also has decadal variation. The analyses show that the winter snow cover days over the Tibetan Plateau and the winter SST over the western Pacific warm pool are important factors to the summer precipitation in the Yellow River basin.
