Chronic kidney disease (CKD) is a global major public health problem. Almost all of previous studies evaluating the prevalence of CKD focused on adults, while studies among the elderly were relatively rare, especially in China. The aim of this study was to investigate the prevalence and associated risk factors of CKD among the elderly in Qingdao, China. This was a cross-sectional study with 38,038 inhabitants (aged 60–109) randomly recruited in Qingdao, China. All participants were required to complete a questionnaire for their demographic characteristics. Blood and urine samples of participants were collected, and the albumin and creatinine levels were measured for albuminuria and estimated glomerular filtration rate (eGFR) assessment. The associations between risk factors and indicators of kidney damage were analyzed by logistic regression. A total of 34,588 inhabitants completed the survey. The overall prevalence of CKD was 11.41% (95% confidence interval (CI): 11.07–11.74%) in the elders from Qingdao in 2016. The prevalence of albuminuria and low eGFR (<60 mL/min per 1·73 m²) were 8.47% (95% CI: 8.17–8.76%) and 3.98% (95% CI: 3.78–4.19%), respectively. Older age, hypertension, diabetes, anemia, hyperuricemia, hyperhomocysteinemia, hypertriglyceridemia, obesity, and LDL-C ≥ 4.1 mmol/L were independently associated with the presence of CKD. In conclusion, common chronic non-communicable diseases, including hypertension, diabetes, obesity, hyperhomocysteinemia, hyperuricemia, and hypertriglyceridemia, were associated with greater prevalence of CKD.
Abstract. Detection and analysis of energy consumption is the information management systems, which not only help producers to expand production, but also rationally plan and use the energy, reduce energy consumption per unit of product, improve economic efficiency. The company managers can have an accurate grasp for the proportion of energy costs and the development trend of enterprises by energy plan, energy monitoring, energy statistics, energy consumption analysis, important energy equipments management, energy metering equipments management and other means. The enterprise energy consumption plan tasks are decomposed to each production sector workshops, which makes energy conservation and responsibilities clear and promotes the healthy and stable development. This paper takes slurry pipeline as background, combining with Silverlight software platform to design the energy detection and analysis management systems based on the digital slurry pipeline. The actual application shows the effectiveness and versatility of the program.
In light of the present condition of the enterprise production management system and single management means, management is not standard, most people are involved in the production management, production management standard is not unified, the production management problems such as difficult maintenance. Based on slurry pipeline as the background, each department management confusion, lack of communication between departments, paper study design a set of integrated automation digital pipeline production management system, the system according to the actual production management needs to establish the management standard specification, implement the working process of motivation, the product producing the intellectualized management maintenance and resource sharing, etc. Practical application shows that the effectiveness and superiority of the scheme.
