50 results about "Bronchopulmonary dysplasia" patented technology

Bronchopulmonary dysplasia (BPD; formerly chronic lung disease of infancy) is a chronic lung disease in which premature infants, usually those who were treated with supplemental oxygen, require long-term oxygen. It is more common in infants with low birth weight (LBW) and those who receive prolonged mechanical ventilation to treat respiratory distress syndrome (RDS). It results in significant morbidity and mortality. The definition of BPD has continued to evolve primarily due to changes in the population, such as more survivors at earlier gestational ages, and improved neonatal management including surfactant, antenatal glucocorticoid therapy, and less aggressive mechanical ventilation.

Household oxygen therapy intelligent management system and method for child patient with bronchopulmonary dysplasia

The invention relates to an intelligent management system and method in the technical field of household oxygen therapy. The system comprises a household oxygen generator and heart rate and blood oxygen saturation degree monitoring equipment; the household oxygen generator is connected into the nostrils of a child patient through a nasal catheter, the heart rate and blood oxygen saturation degreemonitoring equipment comprises a finger vein oxygen monitoring probe connected with the child patient, a control valve of the household oxygen generator is provided with a control module, and a remoteclient side is connected with the control module through a network so that the oxygen flow rate or / and inspired oxygen concentration of the household oxygen generator can be remotely adjusted; the heart rate and blood oxygen saturation degree monitoring equipment comprises a data acquisition module, the data acquisition module is connected with the remote client side through the network, and real-time monitoring data is displayed on the remote client side. The system is reasonable in design, the monitoring data can be timely fed back to the remote client side of an oxygen supply system through the network, real-time control can be achieved, the fine adjustment and intelligent management of the household oxygen therapy are achieved accordingly, and the oxygen saturation degree is maintained within a reasonable range.

Attenuation of hyperoxia-induced cell death with mitochondrial aldehyde dehydrogenase

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.

Prediction marker, prediction model and prediction system for premature infant bronchopulmonary dysplasia

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.
