This study was to evaluate the diagnostic value of anti-cyclic citrullinated peptide (CCP) antibodies in northern Chinese Han patients with rheumatoid arthritis (RA) and its correlation with disease activity. Clinical data and serum samples were collected from 112 RA patients and 55 non-RA patients. Statistical analyses of the correlations among anti-CCP(More)
The urban space expansion is an important indicator for measuring urbanization level. Based on one Landsat MSS image and three Landsat TM images, the urban built-up characteristic of Hong Kong and its impact on the peripheral land during 1973-2004 was analyzed.

Interstitial lung disease (ILD) is a severe extra-articular manifestation of rheumatoid arthritis (RA) that is well-defined as a chronic systemic autoimmune disease. A proportion of patients with RA-associated ILD (RA-ILD) develop pulmonary fibrosis (PF), resulting in poor prognosis and increased lifetime risk. We investigated whether routine clinical(More)
In this paper, we proposed a new strategy for urban land cover classification by fusing high spatial resolution optical images and polarimetric SAR images. The novelty of strategy was in twofold: introduce an object-based classification method to alleviate the negative impact of inner class variability of high spatial resolution images in urban areas and(More)
With more and more serious problem on water pollution, it is significant to monitor the water quality and get to know the trend of the water quality change for water source management and water environment protection. Urban drinking water source quality monitoring system is based on GIS and remote sensing technology. This relatively integrated system(More)
