Objective: Self-management support services can improve patients' self-management ability. This study summarized the best evidence on a self-management support scheme for patients with inflammatory bowel disease based on a mobile health system to accurately describe the current status of the field and provide recommendations for healthcare workers.

Methods: Two researchers retrieved studies from computer decision support systems, guideline websites, official association websites, and databases from the establishment of the database until October 2023.

In this paper, two benzimidazole derivative ligands were obtained using -phenylenediamine and n-pyridine formaldehyde (n = 3, 4) by amine-aldol condensation reactions, which were reacted with selected inorganic metal salts by ambient temperature volatilization method to give compounds : {[(L1)]·[CuI]} , {[L1]·[CuBr]·HO} , {[L2]·[CuBr]}, and {[(L2)]·[CuI]} . They were characterized by IR, UV-Vis absorption spectroscopy, thermogravimetric analysis, and single crystal X-ray analysis. Simultaneously, compounds were found to possess photocatalytic degradation of ciprofloxacin (CIP) by preliminary experimental investigations.

In the process of using lubricating oil, it is inevitable that bubbles will be produced, which can not only accelerate the oil's oxidation and shorten the oil change cycle but also reduce its fluidity and lubricity, aggravate the wear of mechanical parts and produce an air lock that interrupts the oil pump supply and causes an oil shortage accident. This paper mainly and comprehensively discusses the foaming process and its harm, the defoaming mechanism and defoaming method of lubricating oil, more specifically, the synthesis, application, advantages, disadvantages and current situation of three kinds of chemical defoaming agents, namely silicone defoaming agent, non-silicone defoaming agent and compound defoaming agent. Finally, the paper looks forward to the future development of special defoaming agents for lubricating oil.
