Carbon dioxide (CO 2) mitigation in the residential building sector has become critical for China in achieving its carbon peak and neutrality goals. This study is the first to retrospect the historical carbon reduction potential in China's 30 provinces by establishing an equity and efficiency coupling model and comparing the differences in carbon reduction potential under three scenarios: equity priority, efficiency priority scenario, and balance equity with efficiency. The core findings of this study reveal that: (1) China's total CO 2 emissions in residential buildings increased from 975.67 Mt to 1328.47 Mt during 2010–2020, where the provinces with the highest CO 2 emissions are Shandong, Hebei, and Henan; energy intensity and energy carbon emission coefficient are the most critical driving factors affecting the CO 2 emission, followed by floor area per capita and population size. (2) The carbon reduction potential index of residential buildings in eastern provinces is generally higher than that in western provinces; the growth rate of carbon reduction potential is the fastest under the equity priority scenario, and Beijing, Shanghai, and Inner Mongolia have the highest carbon reduction potential. (3) The provinces gradually enter a strong coupling status associated with the climate zones of residential buildings, while the coupling status of the urban area is higher than that of the rural area. Overall, this study adopts a new coupling perspective of equity and efficiency, where the proposed assessment model serves as a reference for measuring the retrospective CO 2 mitigation effect in residential buildings in other countries. • An evaluation approach for the carbon reduction potential of residential buildings was developed. • The core driving factors for carbon emissions from residential buildings were identified. • Three scenarios with distinct preferences for equity and efficiency were determined. • The provincial ranking of carbon reduction potential in urban and rural areas was analyzed. • The causes that promote a strong coupling between equity and efficiency were discussed.

Objectives: DM-related acute/subacute interstitial lung disease (A/S-ILD) remains a big therapeutic challenge due to its insidious onset and rapid development. In the present study, we aimed to investigate the association between clinical features of DM and ILD., Methods: We retrospectively assessed skin manifestations, muscle damage, laboratory tests, concurrent ILD and malignancy in 207 patients with DM and analysed the high-risk factors for ILD., Results: In the 207 DM patients, 153 patients had ILD, in which 131 had chronic ILD (CILD) and 22 had A/S-ILD. The proportions of mechanic's hands, palmar papules and muscle weakness, as well as anti-melanoma differentiation-associated gene 5 (MDA5) antibody and lactic dehydrogenase (LDH), alanine aminotransferase (ALT) and ferritin in the ILD group were significantly higher compared with the non-ILD group. The onset age over 56 years, mechanic's hands and muscle weakness were independent predictive factors for ILD. The proportions of palmar papules, palmar erythema, anti-MDA5 antibody, ALT, aspartate aminotransferase (AST), LDH and ESR in the A/S-ILD group were higher compared with the CILD group. Palmar erythema and palmar papules were independent predictive factors for A/S-ILD. Palmar papules were positively correlated with anti-MDA5 antibody., Conclusion: The onset age over 56 years, mechanic's hands or muscle weakness predicted the incidence of DM-related ILD, while palmar erythema or palmar papules could predict potential DM-related A/S-ILD., (© The Author(s) 2021.
