The northwestern Chinese ecological environment of the semi-arid field is fragile and susceptible to temperature variability. Xixian New Area is the first batch of low impact improvement construction in the northwest semi-arid region, and its greening construction has typical representativeness. As a common ecological facility in the construction of low impact improvement, bioretention facilities have always been a hot research field. With reference to the natural vegetation prototypes in the northwest, the plant landscape can be achieved with drought-resistant water and long-term stability by constructing the ground cover plant community. Based on the investigation and division of types of bioretention facilities, the research proposed the design strategy of the vegetative planting of the bioretention facilities in the semi-arid and semi-humid region of northwest China. The research summarized the resistance of 50 ground cover plants to sorghum, pollution and drought tolerance, and divided them into different levels. Taking the three practice projects of bioretention facilities as the example, the recommendations and models for optimization of shrub and groundcover plant selection and planting design were summarized, providing theoretical basis for the construction of low impact improvement urban green space and ecosystem improvement. The key parameters of the plant cover community design of biological detention facilities and the combinations of four dominant types of plant cover communities were extracted.

Dementia has been increasingly paid attention by policymakers in China. However, the majority of the public has an indistinct concept of dementia and its diagnostic criteria. Therefore, many abnormal characteristics and actions of older people are labeled as having dementia while diagnosed without dementia. We examined a multi-stage cluster sample of 11,223 participants aged 60 years and above who have been clinically confirmed by general practitioners as not having dementia in 2013, and 7,861 participants were willing to participate the following study and were followed-up in 2014. To assess the differences of status of older people who were mistakenly labeled as having dementia or not, we asked main caregivers 'Do you think this older person suffers from dementia?', and found out that 244 participants had been mistakenly labeled as having dementia since 2013. Related effects were measured using international generic scales as well, and the results showed that participants with better physical status deteriorated more rapidly if they were mistakenly labeled as having dementia. Additionally, the mental health of these 244 participants also deteriorated more quickly. Older adults that were not labeled as having dementia were more willing to participate in social activities relative to their labeled counterparts. In conclusion, being mistakenly labeled as having dementia without a medical diagnosis impaired older adults' physical functioning and mental health. Moreover, the reduction of social activities of labeled older people leads to separation and social exclusion. [ABSTRACT FROM AUTHOR]

Abstract: This paper takes advantage of the integration of subtraction clustering and fuzzy c-means clustering algorithm to obtain precise number of clusters and the degree of membership, and establishes the neural network model based on the multiple criterion information fusion and the fuzzy technology. Collecting a variety of data in actual underground mining process and integrating them as a whole, the simulations are performed. Experimental results indicate that the proposed method is valid.

The article investigates the efficacy of Pseudomonas aeruginosa Exotoxin A (PEA) in inducing liver injury in rats for experimental purposes. The main objective of the experiment is to increase serum enzymes in rats as well as alter liver histology. It has been proven that PEA is a microorganism responsible for various sickness including septic shock, respiratory distress and wound infections as it elaborates varieties of toxic components resulting into liver damage. It has been regularly used in experiments especially in causing liver damage in experimental animals.
