Esophageal squamous cell carcinoma (ESCC) is one of the most common cancers in developing countries. The aim of the study was to determine the association between serum CD26 concentration and outcome of patients with ESCC.A total of 183 patients with ESCC and 254 healthy controls were selected. Blood samples were obtained from the participants. The serum level of CD26 was detected using a commercial...
Inflammation plays a pivotal role in coronary heart disease. Dendritic cells (DCs) are principal players in inflammation and atherosclerosis. Although the percentage of circulating DC precursors in coronary heart disease have been investigated, circulating myeloid DC (mDC) and plasmacytoid DC (pDC) precursors have not been extensively studied, particularly in relation to the severity of coronary artery...
As various information resource of education and teaching process, implementation and using the education resource is the nucleus of education information-based By the analysis to education resource management system, this text search according to the feasibility that OSS sets up resource management system, then Liferay can become the technique platform that sets up resource management portal; the...
In this paper, the organic-inorganic complex prepared by degradation of liquid manure and bentonite was used as adsorbent. And NaNO3 was used as nitrogen salt, KCL as potassium salt, and CuSO4 · 5H2O provided Cu2+. Different concentrations of nitrogen and potassium salt were prepared to carry adsorption reaction with certain concentration of Cu2+ in aqueous solution. Through these experiments, study...
In this paper, the surface water and sediments of gold mining area in Xiaoqinling, Puyugou were taken as the research objects to investigate the enrichment of heavy metals. Contents of various heavy metals in the surface water and sediments were tested systematically. The osculating method and index's method of pollution of heavy metal were used together to evaluate and analyze the test results. The...
In this paper, organic-inorganic complex which is prepared by organically modifying inorganic materials bentonite with natural organic material manure as modifier was used for the adsorption of Pb2+ from aqueous solutions. The influence of adsorption time, temperature, pH value and dosage on the removal of Pb2+ was evaluated. Then, KNO3 and HCl were used for desorption of Pb2+ to study the adsorption...
Target localization system is one of the basic aspects for mobile robot navigation. One of the most popular navigation way is the navigation based on visual. But, this way is limited by the light and the field of view so that it can't accurately detect the targets in special environments. To resolve the above problem of target localization way based on visual, this paper has studied the sound source...
Against the issue about revenue maximization of cycle project product, apply ideas of game balance, base on a single product manufacturers and retailers in closed-loop system, study when recycling waste products, decentralized decision-making model and a joint pricing strategies of enterprises; In considering the environmental costs of products, proposed differential pricing policy model in product...
The content of total flavonoids in peanut hulls was determined by the extraction technology of cellulose and ethanol using efficiently peanut hulls as raw materials in this paper. The extract was purified by AB-8 macroporous resin. The structure of the product had been characterized with UV- spectrum and IR- spectrum. The results showed that: the enzyme amount was 0.8%, the temperature was 40??, the...
