We conducted an observational cohort study of children with CHD undergoing cardiac surgery in a single tertiary center between January 2019 and August 2021 ( n = 362). In this study we assessed incidence, risk factors, and outcomes of postoperative AKI, while testing the hypothesis that, depending on the underlying diagnosis, there would be significant differences in AKI incidence among different diagnostic groups. The method of annual spatial-temporal analysis of urban ecology in this paper can be applied in similar studies on other cities, and the results obtained for Guilin have reference value for future urban planning and environmental protection work.Īcute Kidney Injury (AKI) commonly complicates cardiac surgery in children with congenital heart disease (CHD). CCDM has shifted from low to high coupling coordination, and the relationship between urban development and the ecological environment has improved. ![]() The overall ecological quality of the main urban area of Guilin has improved significantly, while local ecological pressure in Lingui District has increased. NTLI in 2020 was 7.72 times higher than in 2000. The results showed that the urban area of Guilin’s urbanization had developed rapidly over the past 20 years. From the dynamic time-series changes of CCDM, the urban development and ecological environment of the urban area of Guilin, from 2000 to 2020, were analyzed. The coupling coordination degree model (CCDM) was built. The remote sensing ecological index (RSEI) model was established in this study by using four indexes: greenness, wetness, dryness and heat. This paper constructed a night-time light index (NTLI) based on DMSP/OLS, NPP/VIIRS night-time light data in response to these problems. Analyzing its coupling coordination between urbanization and ecology is vital for subsequent sustainable development. Guilin is famous as an international tourist destination in Chine. Few annual ecological studies have been conducted on tourist-oriented cities. Urban development in developing regions increases ecological and environmental pressures.
