Abstract : Based on the analysis of air quality data in Yunnan Province from 2015 to 2020, combined with spatial interpolation analysis and geographic detector factor analysis, the spatial–temporal evolution characteristics of air quality in Yunnan Province have been studied, and the main driving factors, the mechanisms, and the impact of regional COVID-19 control measures affecting air quality have been discussed.

Method details Fertilization, culture and embryo collection Superovulation was implemented for B6D2F1 female mice. The mice were intraperitoneally injected with 5 IU of pregnant mare serum gonadotropin (PMSG) (San-Sheng, China) and with 7 IU of human chorionic gonadotropin (hCG) (San-Sheng) 48 h later. Superovulated females were mated with B6D2F1 males or subjected to IVF procedures. Briefly, cumulus-oocyte complexes were collected from the oviducts 13–14 h after hCG injection.
