Signifcant advancements have been made in recent years in the development of highly sophisticated skin *** as three-dimensional(3D)models that mimic human skin,these organoids have evolved into complex structures and are increasingly recognized as efective alternatives to traditional culture models and human skin due to their ability to overcome the limitations of two-dimensional(2D)systems and ethical *** inherent plasticity of skin organoids allows for their construction into physiological and pathological models,enabling the study of skin development and dynamic *** review provides an overview of the pivotal work in the progression from 3D layered epidermis to cyst-like skin organoids with ***,it highlights the latest advancements in organoid construction facilitated by state-of-the-art engineering techniques,such as 3D printing and microfuidic *** review also summarizes and discusses the diverse applications of skin organoids in developmental biology,disease modelling,regenerative medicine,and personalized medicine,while considering their prospects and limitations.

Lockdown and re-opening may become cyclical due to the recurrent waves of the COVID-19 *** studies have examined temporal trends and determinants of in-hospital mortality among patients with ST-segment elevation myocardial infarction(STEMI),a life-threatening condition that requires emergency medical *** nation-wide data before,during and after the Wuhan lockdown,we aimed to depict temporal patterns and major determinants of STEMI in-hospital mortality in china across five time periods of the COVID-19 *** analyzed the data of 283,661 STEMI patients who were admitted to 4,487 chest-pain-centers across china,from January 1,2019 to May 31,*** with the period before the lockdown,STEMI in-hospital mortality increased by 25%(OR 1.25,95%CI 1.16–1.34)during Early Lockdown,by 12%(OR 1.12,95%CI 1.03–1.22)during Later Lockdown,by 35%(OR 1.35,95%CI 1.21–1.50)during Early Lift,and returned to pre-COVID risk(OR 1.04,95%CI 0.95–1.14)during Later *** each time-period,we observed a clear mortality gradient by timing and types of revascularization *** conclusion,the COVID-19 epidemic had a significant adverse impact on STEMI in-hospital mortality,with bimodal peaks during early lockdown and early lift periods and clear mortality gradients by timing and types of revascularization procedure,independent of the time periods.
