[Examination of cerebral electrical admittance plethysmogram in healthy newborns].

Objective: Cerebral electrical admittance plethysmography is a novel noninvasive technique for evaluating cerebral hemodynamics. This study aimed to measure the reference values of cerebral electrical admittance plethysmogram in healthy newborns.

Methods: Bilateral cerebral electrical admittance plethysmography was performed in 40 healthy newborns.

[Analysis of sterile male semen of occupational drivers].

Objective: To explore the possible correlation between the driver's occupation and male semen quality.

Methods: Semen samples were collected from 1,223 infertile men (78 drivers and 1,145 non-drivers) and 100 normal men, and their liquefaction, sperm density, sperm vitality, sperm motility and sperm shape were analysed.

Results: The abnormal rates of semen quality in sterile male drivers were significantly higher than in non-drivers(P < 0.
