Oxygen toxicity is one of the major risk factors in the development of the chronic lung disease or bronchopulmonary dysplasia in premature infants. Using proteomic analysis, we discovered mitochondrial aldehyde dehydrogenase (mtALDH or ALDH2) was down-regulated in neonatal rat lung after hyperoxic exposure. To study the role of mtALDH in hyperoxic lung injury, we overexpressed mtALDH in human lung epithelial cells (A549) and found that mtALDH significantly reduced hyperoxia-induced cell death. Compared to control cells (Neo-A549), the necrotic cell death in mtALDH overexpressing cells (mtALDH-A549) decreased from 25.3% to 6.5%, 50.5% to 9.1% and 52.4% to 15.06% after 24-, 48- and 72-hour hyperoxic exposure, respectively. The levels of intracellular and mitochondria-derived reactive oxygen species (ROS) in mtALDH-A549 cells after hyperoxic exposure were significantly lowered compared to Neo-A549 cells. mtALDH overexpression significantly stimulated extracellular signal regulated kinase (ERK) phosphorylation under normoxic and hyperoxic conditions. Inhibition of ERK phosphorylation partially eliminated the protective effect of mtALDH in hyperoxia-induced cell death, suggesting ERK activation by mtALDH conferred cellular resistance to hyperoxia. mtALDH overexpression augmented Akt phosphorylation and maintained the total Akt level in mtALDH-A549 cells under normoxic and hyperoxic conditions. Inhibition of PI3K activation by LY294002 in mtALDH-A549 cells significantly increased necrotic cell death after hyperoxic exposure, indicating that PI3K / Akt activation by mtALDH played an important role in cell survival after hyperoxia. Taken together, these data demonstrate that mtALDH overexpression attenuates hyperoxia-induced cell death in lung epithelial cells through reduction of ROS, activation of ERK / MAPK and PI3K / Akt cell survival signaling pathways.

The invention discloses a predictive marker, a predictive model and a predictive system for bronchial lung dysplasia of a premature infant. EUGR, caffeine treatment days, total oxygen uptake days and LMR are independent risk factors of BPD occurrence of the premature infant. The lung ultrasound prompts the occurrence rate of the severe alveolar interstitial syndrome on the third day after the premature infant is born, the lung ultrasound prompts the pleural line change on the 28th day after the premature infant is born, and the occurrence rate of the alveolar interstitial syndrome, the pulmonary metaplasia or the fragment symptom has a prediction effect on the occurrence of the BPD. The serum eNOS level of a child patient in a BPD group on the first day after birth is remarkably higher than that of a child patient in a non-BPD group and is in positive correlation with the severity of BPD, and when the serum eNOS level of the child patient on the first day after birth is larger than 6.48 ng / ml, the risk that a premature infant suffers from BPD is obviously increased. The BPD occurrence of the premature infant can be well predicted by constructing a regression model through combination of six indexes, namely the serum eNOS (1d) level, the severe alveolar interstitial syndrome (3d), EUGR, caffeine treatment days, the total oxygen uptake days and LMR6 indexes.
