Ten-Year Trend of Retinopathy of Prematurity Among Extremely Preterm Infants in One Neonatal Intensive Care Unit in China.

Extremely preterm (EP) infants are at the highest risk of retinopathy of prematurity (ROP). With more EP infants survived in China, recent data of ROP is lacking. The aim of the study is to report the trend of incidence of ROP among EP infants in a large neonatal intensive care unit in China over the past 10-year period, in relation with the overall survival rate and the change of oxygen saturation targets.

Incidence of retinopathy of prematurity treatment in extremely preterm infants in China.

Background: Retinopathy of prematurity (ROP) continues to be a major cause of visual impairment and blindness in premature infants and children.

Objectives: To investigate the incidence of severe ROP receiving treatment in extremely preterm (EP) infants in China over time. The risk factors for ROP treatment were also assessed.

Sensitivity of nPCR for four types of membrane protein DNA and of two pairs of primers for Tpp47 DNA of Treponema pallidum in whole blood of congenital syphilis newborns.

Background: Problems exist in congenital syphilis (CS) diagnosis and no single test can be used to diagnose CS.

Objective: To know whether there exist differences of nested polymerase chain reaction (nPCR) sensitivity among four membrane protein DNA and of nPCR between two pairs of primers for Tpp47.

Methods: We collected 30 CS patients as a study group, and 20 cases admitted to hospital for other reasons as a control group.
