[A multicenter survey of antibiotic use in very and extremely low birth weight infants in Hunan Province].

Objective: To investigate the current status of antibiotic use for very and extremely low birth weight (VLBW/ELBW) infants in neonatal intensive care units (NICUs) of Hunan Province.

Methods: The use of antibiotics was investigated in multiple level 3 NICUs of Hunan Province for VLBW and ELBW infants born between January, 2017 and December, 2017.

Green tea polyphenols protect against preglomerular arteriopathy via the jagged1/notch1 pathway.

Preglomerular arteriopathy (PA) induced by hyperuricemia contributes to the progression of chronic kidney disease (CKD). Green tea polyphenols (GTPs) are antioxidant ingredients thought to assist in preventing hyperuricemia. However, the underlying mechanism by which GTPs affect renal function remains unclear.

[Changes in T lymphocyte subsets in preterm infants with intrauterine growth retardation].

Objective: To study changes in T lymphocyte subsets in preterm infants with intrauterine growth retardation (IUGR).

Methods: The study enrolled 29 IUGR preterm infants, 38 preterm infants born appropriate for gestational age (AGA), and 20 healthy full-term infants. Peripheral blood was sampled during the first 24 hours of life, and again at a corrected age of 38 weeks of the preterm infants.
