According to the actual requirements of the drilling data warehouse, this paper analyses the weaknesses of traditional Extract, Transform and Load (ETL) tools' architecture of its openness and repeatedly development, and proposed a three-layers-architecture based on metadata. That makes ETL process more efficient, multipurpose and flexible. Through(More)
Follicular T regulatory (Tfr) cells inhibit follicular T helper (Tfh) cells mediated B cell responses. Tfh cells are involved in the pathogenesis of systemic lupus erythematosus (SLE). However, the role of Tfr cells in SLE remains unclear. The frequency of circulating Tfr and Tfh cells were examined in SLE patients and healthy controls. The frequency of(More)
During the oil drilling process, the quality of cementing directly impacts on following operations. According to the operating procedure of cementing, this paper classifies the effecting factors of cementing quality to two types. Classification one is displacement efficiency and another is WOC (Wait on Cement) effect. Through the methodology of multi-level(More)
OBJECTIVE Development of proteinuria in lupus nephritis (LN) is associated with podocyte dysfunction. The NLRP3 inflammasome has been implicated in the pathogenesis of LN. The purpose of this study was to investigate whether NLRP3 inflammasome activation is involved in the development of podocyte injury in LN. METHODS A fluorescence-labeled caspase 1(More)
This paper proposes a web-based On Line Analyse Process (OLAP) structure due to the weaknesses of OLAP system within the conventional Client/Server(C/S) structure. Studied with actual examples, a multidimensional model of web-based OLAP drilling analysis system has been designed, by applying the methods of link between Office Web Components and analysis(More)
