Gout is a metabolic bone and joint disease caused by purine metabolism disorder.The disturbance of inflammatory microenvironment caused by monosodium urate(MSU)deposition is an important pathological mechanism of gout occurrence and development.In the understanding of Traditional Chinese medicine(TCM),the interaction of"dampness","heat"and"stasis"is the main pathogenesis of gout,and the method of clearing heat and removing dampness is the main treatment method of TCM for gout.In recent years,studies have found that heat-clearing and dampness-removing method can improve the TCM symptom score of gout patients,especially in the body tiredness,dry mouth and dry throat,short yellow urine,thirsty,etc.,which are the characteristics of dampness and heat syndrome,this may be related to the fact that the TCM heat-clearing and dampness-removing method in the treatment of gout removes the appearance of dampness and heat,improves the inflammatory microenvironment of gout and restores the normal metabolic function of human body.This paper deeply explores the specific mechanism of TCM heat-clearing and dampness-removing method to improve the inflammatory microenvironment of gout,which can provide new ideas for the diagnosis and treatment of clinical gout. 展开更多

Dispersed and peripheral spaces in the urban core are influenced both by the trend towards constant growth as well as social ways of life which are constantly evolving. Following a connotation, these two factors therefore play a crucial role in defining the alternation of urban space--in particular, that of the centers. The main focus of this research article is on the methodology used in the survey and evaluation of "centralities" as well as their developments over the past four decades (1974-2014) in approaches to urban development that has been developed in Graz.~ The analysis has drawn on the four editions ("evolution") of approaches to urban development as conceived by the city of Graz in order to examine their verbal characteristics in regard to centralities. At the same time, the analysis does not examine presentations of plans which exist in supplementary forms (e.g., explanatory reports and supplemented plans)--it restricts itself solely to the various plans set out in the STEKs.2 The highest degree of accuracy has been applied to the notion of "centralis" in approaches to urban development. The goal of the research project was to depict the modulation of the notion of "centrality" in the urban context as a space-forming dimension. Furthermore, it clearly shows the extent to which the notion of the "centre" (in the widest sense of the word) has become distanced from qualitative, spatial development and at the current time of urban development is experiencing a sort of Renaissance. In the field of "urban development", architectural references in the context of"centrality" have scarcely been researched. This has led to the opening-up of a complex interdisciplinary research field. In order to make the complex architectural determinants of "centrality" more accessible to the participating disciplines, approaches to urban development have been explored in the form of a social and spatial analysis. 展开更多

The greatest difficulties in recognizing geochemical hydrocarbon anomalies are: (1) how to objectively and accurately separate anomalies from background; (2) how to distinguish hydrocarbon pool related apical anomalies from lateral anomalies controlled by faults; and (3) how to eliminate interferences. These uncertainties are serious obstacles for the wide acceptance and use of geochemical techniques in hydrocarbon exploration. In this paper, the features of hydrocarbon anomalies were analyzed based on the micro migration mechanisms. In most cases, there are two anomalous populations or point groups, which are produced by two distinct mechanisms: (1) a population that directly reflects oil and gas fields, and (2) one that is related to structures such as faults. Statistical studies show that background anomalous populations and the boundaries between them can be described by the population means, prior probabilities, which are the proportions of population sizes, and covariance matrices, when background and anomalous populations have normal distributions. When this normality condition is met, a series of formulas can be derived. The method is designed on the basis of these allows: (1) univariate anomaly recognition, (2) elimination of interferences, (3) multivariate anomaly recognition, and (4) multivariate anomaly combination which depicts a more representative picture of morphology of the anomalous target than individual anomalies. The univariate and multivariate anomaly recognition can not only separate anomalies from background objectively, but also simultaneously distinguish the two types of anomalies objectively. This method was applied to the hydrocarbon data in Yangshuiwu region, Hebei Province. The interferences from regional variation of background were eliminated, and the interpretation uncertainty was reduced greatly as the anomalous populations were separated. The method was also used in Daxing region within the confines of Beijing City, and Aershan and Jiergalangtu regions in Inner Mongolia. 展开更多

Rare earth elements (REEs) have been proved ideal tracers for soil erosion and aggregation. REE tracer method (REETM) used to study soil erosion, as a new technique, has been developed in recent 20 yr. It is able to quantitatively monitor the temporal and spatial variation of erosion intensity, compared with traditional approaches. The applications of REETM in studying of sediment differentiation law, erosion process evolution, determination of sediment sources and sedimentation investigations, and determination of prediction parameters, were reviewed. Some application limitations were summarized. 展开更多

This paper is devoted to study the multiobjective system programming under the assumption that some of the problem parameters are random variables. A method called Interactive Reference Goal Satisfied Degree and Feasible Degree (IRGSD-FD) is developed to solve stochastic multiobjective problems. It is an interactive method providing a so-called `dialogue' between the user and the model, the decision maker having the option conducting the search process for the (α, β)-efficient solutions by modifying the initial conditions according to the partial results obtained. During the iterations, the decision maker can improve upon the reference goal or called aspiration level already attained by one objective function as well as upon the probability of reaching the corresponding objective or called satisfied degree (or both), or/and the probability of satisfying the constraint or called feasible degree already attained by the constraint. Finally, the application of IRGSD-FD method in the resource allocation problem is discussed with a case study for project investment management. 展开更多
