Objective: To grasp the research dynamics and development trend of the thermal environment of campus buildings in China, so as to lay the foundation for in depth research and provide a reference basis. Methods: Based on 479 documents in CNKI from 2000 to 2020, the documents were visualized and analyzed by keywords, including co occurrence, clustering, outbreak and author cooperation network in CiteSpace. Results: In the past 20 years, the research on thermal environment of campus buildings in China had gone through a period of formation development growth, and was at a high growth stage now. The word frequency of "thermal comfort, thermal environment, indoor thermal environment, natural ventilation" was greater than 50, which was a high frequency keyword. The highest outbreak rate of "green campus" was 3.75, and "university library, university building, microclimate and green building" was in the outbreak period. And LIU Jiaping, LIU Zehua, WANG Hongguang and others were highly productive authors and have formed cooperative network groups with their own cores, but the cooperation among the network groups was less to be strengthened. Conclusion The research dynamics of the thermal environment of campus buildings is closely related to the policy development in China, and the research on "green campus, campus energy saving optimization, and university buildings" based on human thermal comfort theory is a hot topic of continuous attention.

OBJECTIVE: To investigate the nutritional status of critically ill hospitalized children and to explore the value of nutritional risk screening tools in the nutritional risk assessment. METHODS: The clinical data of 211 critically ill children who were admitted to the pediatric intensive care unit from November 2017 to April 2018 were collected to evaluate their nutritional status on admission and at discharge. Two nutritional risk screening tools, STRONGkids and PYMS, were used for nutritional risk screening in the 211 children. RESULTS: Among the 211 patients, 68 (32.2%) were found to have malnutrition on admission, with 34 cases each of moderate and severe malnutrition. Moderate or high nutritional risk was found in 154 cases (73.0%) with STRONGkids and 165 cases (78.2%) with PYMS. Using weight-for-age Z-score as the gold standard to evaluate the efficacy of the two nutritional risk screening tools, the areas under the receiver operating characteristic curves of STRONGkids and PYMS were 0.822 and 0.759 respectively. Both tools had a significant clinical value in screening for malnutrition (P<0.05), but there was no significant difference in clinical efficacy between them (P>0.05). With the optimal cut-off value of 3 points, the sensitivities of STRONGkids and PYMS for screening of malnutrition were 92.1% and 76.2% respectively. The children with moderate or high nutritional risk on admission had a significantly poorer prognosis than those with low nutritional risk (P=0.014 and 0.001 respectively). The children with severe malnutrition had a significantly poorer prognosis than those with normal nutrition (P=0.0009). CONCLUSIONS The detection rates of malnutrition and nutritional risk are high in critically ill children. Malnutrition/high nutritional risk is related to a poor prognosis. Both STRONGkids and PYMS have a clinical value for nutritional risk screening in critically ill children, and they have similar clinical efficacy; however, STRONGkids is more sensitive.
