Alzheimer's disease (AD) is a most common neurodegenerative disease. Sodium Tanshinone IIA Sulfonate (STS) has been reported to ameliorate AD pathology. However, the underlying mechanism is still unclear.

[Assessment and management of difficult airways in neonates with Pierre Robin sequence].

Objective: To assess the difficult airways preoperatively in neonates with Pierre Robin sequence (PRS).

Methods: A total of 18 newborn PRS with difficult intubation were evaluated with the assessment grade. The scores were based upon clinical observation, weight gain, airway obstruction and Cormack-Lehane classification.
