Objective:To compare the efficacy and safety of bi-level positive airway pressure (BiPAP) ventilation and heated humidified high flow nasal cannula (HHHFNC) ventilation as initial respiratory support for premature infants with respiratory distress syndrome (RDS).Methods:From January 2019 to June 2021, premature infants [gestational age (GA) 28~35 weeks)] with grade Ⅰ to Ⅲ RDS admitted to Suining County People's Hospital were prospectively enrolled. The infants were randomly assigned into BiPAP group and HHHFNC group. The clinical characteristics, ventilation efficacy and complications were analyzed.Results:A total of 33 infants were in BiPAP group and 32 in HHHFNC group. No significant differences existed between the two groups in the following items: the frequency of apnea within 24 h of ventilation, FiO 2 and PaCO 2 at 24 h, the use of pulmonary surfactant (PS), the incidence of non-invasive ventilation failure within 72 h, non-invasive ventilation duration and the age achieving total enteral nutrition. HHHFNC group had lower score in premature infants pain profile (PIPP) than BiPAP group at 24 h of non-invasive ventilation [4 (3, 6) vs. 8 (6, 11), P<0.001]. No significant differences existed in nasal injury, pneumothorax, intraventricular hemorrhage, necrotizing enterocolitis, bronchopulmonary dysplasia and mortality rate between the two groups ( P>0.05). Conclusions:As the initial treatment for premature infants with grade Ⅰ to Ⅲ RDS, BiPAP and HHHFNC has similar rates of non-invasive ventilation failure within 72 h,non-invasive ventilation duration and adverse events. HHHFNC may ease the pain of the infants.

Abstract OBJECTIVE To explore the material basis and mechanism of Crataegi Fructus in improving metabolic hypertension(MH) by using network pharmacology and molecular docking technique.METHODS The components of Crataegi Fructus were collected by HERB, ETCM database and literature survey; screening all ingredients of Crataegi Fructus to improve MH targets through databases such as SwissTargetPrediction and GeneCards; build "active ingredient-target-disease" network of Crataegi Fructus with Cytoscape software; DAVID was used to analyze GO enrichment and KEGG pathway. The core components and core targets were verified by molecular docking with Autodock software. RESULTS The total of 89 active components were screened from Crataegi Fructus and acted on 84 targets. Among them, the core active components of Crataegi Fructus to improve MH were maslinic acid, fomefficinic acid B, linolenic acid, linoleic acid, methyl-n-nonylketone, apigenin, ursolic acid, etc. The core targets were CYP19A1, PPARA, ESR1, PTGS2, PPARG, NR3C1, MMP9, TNF, etc. The mechanism of action mainly involved multiple signaling pathways such as inflammation, glycolipid metabolism, and vascular endothelial function. Molecular docking showed that the core active ingredients of Crataegi Fructus had high affinity with core targets. CONCLUSION Crataegi Fructus may regulate multiple signaling pathways such as TNF, IL-17, AGE-RAGE, HIF-1, cGMP-PKG through multi-component regulation, thereby inhibiting inflammatory response, improving glucose and lipid metabolism abnormalities, and improving vascular endothelial function, so as to comprehensively exert the role of improving MH in various aspects.
