In order to adapt to the management mode of the products pipeline network under the new system, set up a service-oriented pipeline system and make for the universality of batch tracking technology, a discussion was made about the products pipeline batch interface tracking technology under the PipeChina system. First of all, the oil batch coding rules and operation terms were standardized from the perspective of information level, which is favorable to the popularization and application. In terms of the development environment, it was considered an effective way to apply online real-time tracking to the accuracy improvement of products pipeline batch interface tracking software(hereinafter referred to as the tracking software), as well as the best way to develop the tracking software on the domestic SCADA system. In respect of technical scheme design, an interface tracking method with 50% concentration point(vol%) was determined and a design was made to the function and flow of tracking software. In response to the key challenges, the accuracy, calibration and error correction of batch tracking were analyzed and verified by the field application results. The customization and universality of the tracking software were discussed from three aspects: data system, oil transportation technology and model coefficient. As a result, an idea was proposed to design the tracking software interface from the software function level. Generally, the research results lay a foundation for the research on accurate products pipeline batch interface tracking technology and the opening of a new control mode of products pipeline network.

Objective To evaluate the effect of Jintiange capsule on the levels of MMP-3, TIMP4, IL-1β, and TGF-β1 in synovial fluid of patients with knee osteoarthritis (KOA). Methods Ninety KOA patients were involved. WOMAC scores were used to evaluate the knee joint function before the treatment and after one and two courses of the treatment. The synovial fluid in knee joint was collected and the levels of MMP-3, TIMP-1, IL-1β, and TGF-β1 in the synovial fluid were detected using ELISA method. Results 1) After oral intake of Jintiange capsule, WOMAC scores of the patients decreased significantly, and the knee joint function improved. 2) The levels of MMP-3 and IL4P in synovial fluid after the treatment gradually decreased comparing to those before the treatment, and the levels of TIMP-1 and TGF-β1 in the synovial fluid gradually increased ( P < 0. 01). 3) Following the increase of the time course of Jintiange treatment, the levels of MMP-3 and IL-17#946; in synovial fluid decreased and the levels of TIM-1 and TGF-β1 and TGF-β1 increased. The differences between the groups were significant (P < 0. 01). Conclusion Jintiange capsule can markedly decrease the levels of MMP-3 and IL-1β, and increase the levels of TIM-1 and TGF-β1 in synovial fluid. Thus, Jintiange Capsule can protect the articular cartilage and improve the knee joint function of KOA patients. [ABSTRACT FROM AUTHOR]
