Variations in length of stay among survived very preterm infants admitted to Chinese neonatal intensive care units.

Background: This study aimed to describe length of stay (LOS) to discharge and site variations among very preterm infants (VPIs) admitted to 57 Chinese neonatal intensive care units (NICUs) and to investigate factors associated with LOS for VPIs.

Methods: This retrospective multicenter cohort study enrolled all infants < 32 weeks' gestation and admitted to 57 NICUs which had participated in the Chinese Neonatal Network, within 7 days after birth in 2019. Exclusion criteria included major congenital anomalies, NICU deaths, discharge against medical advice, transfer to non-participating hospitals, and missing discharge date.

Effects of mild-warming moxibustion on Bcl-2 and PKC expressions of peripheral blood in elderly people.

Objective: To explore the anti-aging effects of mild-warming moxibustion on Bcl-2 and PKC expression in peripheral blood and general symptoms in elderly people.

Methods: A total of 61 elderly people and 30 non-elderly people were enrolled. The total effective rate of mild-warming moxibustion was assessed by symptom scores, and Bcl-2 and PKC expression in peripheral blood was detected by flow cytometry.
