This study is aimed at exploring the effect of pulmonary surfactant (PS) combined with noninvasive positive pressure ventilation on the levels of Keratin-14 (KRT-14) and Endothelin-1 (ET-1) in peripheral blood and the therapeutic effect of neonatal respiratory distress syndrome (NRDS). Altogether 137 cases of neonates with respiratory distress syndrome treated in our hospital from April 2016 to July 2018 were collected. Among them, 64 cases treated with noninvasive positive pressure ventilation were considered as the control group, and 73 cases treated with PS combined with noninvasive positive pressure ventilation were considered as the observation group. The expression of KRT-14 and ET-1 in the two groups was compared. The therapeutic effect, death, complications, and blood gas indexes PaO2, PaCO2, and PaO2/FiO2 in the two groups were compared. Receiver operating characteristic curve (ROC) was applied to analyze the diagnostic value of KRT-14 and ET-1 in the therapeutic effect of NRDS. The effective rate of the observation group was higher than that of the control group. After treatment, PaO2 and PaO2/FiO2 in both groups were notably higher than that before treatment, while PaCO2 was notably lower than that before treatment. And after treatment, the levels of PaO2 and PaO2/FiO2 in the observation group were remarkably higher than that in the control group; PaCO2 was notably lower than that in the control group. After treatment, the levels of KRT-14 and ET-1 in the two groups were remarkably lower than those before treatment, and the levels of KRT-14 and ET-1 in the observation group were considerably lower than those in the control group after treatment. ROC curve showed that the area under the curve (AUC) of KRT-14 was 0.791, and the AUC of ET-1 was 0.816. PS combined with noninvasive positive pressure ventilation can notably improve the therapeutic effect of NRDS. KRT-14 and ET-1 levels may be potential therapeutic diagnostic indicators.

Objective: To analyze the clinical effect of nasal continuous positive airway pressure (CPAP) combined with pulmonary surfactant in the treatment of neonatal respiratory distress syndrome (NRDS). Methods: Eighty-two NRDS patients who received treatment from August 2017 to June 2019 in our hospital were selected and divided into a control group and an observation group using random number table, 41 in each group. The control group was treated with CPAP, and the observation group was treated with pulmonary surfactant injection besides CPAP. The therapeutic effect, blood gas index, mechanical ventilation parameters and occurrence of complications were compared between the two groups. Results: The total response rate of the observation group was 90.24%, which was significantly higher than 70.73% of the control group, and the difference had statistical significance (P<0.05). After treatment, the improvement of blood gas indexes of the observation group was better than that of the control group. The hospitalization time and duration of oxygen treatment of the observation group were shorter than those of the control group, and the hospitalization cost was higher than the control group (P<0.05). The difference of incidence of complications between the two groups was statistically significant (P<0.05). Conclusion: Endotracheal injection of pulmonary surfactant combined with CPAP in the treatment of NRDS can enhance the efficacy, promote the recovery of blood gas index, and reduce the parameters of mechanical ventilation and the incidence of complications, which is conducive to improving the respiratory function of the newborn. The therapy is worth application in the treatment of NRDS patients. doi: https://doi.org/10.12669/pjms.36.4.1963 How to cite this:Miao J, Xie H, Zhang Y, Guo X, Cui M.

Summary Background: The aim of this study was to investigate the role of pulmonary surfactant-associated protein B (SP-B) expression in the pathogenesis of neonatal respiratory distress syndrome (RDS) via detecting the protein and mRNA expression of SP-B. Methods: A total of 60 unrelated neonates who died of RDS were chosen as the RDS group and then subgrouped into ≤32 weeks group, 32∼37 weeks group and ≥37 weeks group (n=20). Sixty neonates who died of other diseases were enrolled as controls and subdivided into 3 matched groups based on the gestational age. Western blot assay and RT-PCR were employed. Results: In the RDS group, SP-B protein expression was reduced or deficient in 8 neonates of which 6 had no SP-B protein expression. In the control group, only 1 had reduced SP-B protein expression. The reduced or deficient SP-B protein expression in 9 neonates of both groups was noted in the ≥37 weeks group. In the RDS group, the SP-B mRNA expression was significantly lower than that in the control group. In the ≤37 weeks group, SP-B mRNA expression was comparable between the RDS group and control group. In the 32∼37 weeks group, the SP-B mRNA expression in the RDS group was significantly reduced when compared with the control group. In the ≥37 weeks group, the SP-B mRNA expression in the RDS group was dramatically lower than that in the control group. Conclusions: Alteration of SP-B expression is present at transcriptional and translational levels. Reduction of SP-B mRNA and protein expression is involved in the pathogenesis of RDS.

Objective. To analyze the expression of miR-127 in the serum of patients with acute respiratory distress syndrome (ARDS) and to explore its correlation with the severity of ARDS patients and its value as a molecular marker for diagnosis of ARDS. Methods. 70 patients with ARDS admitted to our hospital from September 2017 to September 2019 were selected as the observation group, and 60 healthy persons with physical examination were collected as the control group. RT-PCR was used to detect the serum miR-127 levels of all subjects, and the serum miR-127 levels of the observation group and control group were compared. The oxygenation index (PaO2/FiO2) of ARDS patients was recorded and divided into three subgroups: mild group, moderate group, and severe group. Serum miR-127 levels of patients in the mild group, moderate group, and severe group were compared. Pearson correlation was used to analyze the relationship between serum miR-127 levels and the severity of ARDS patients. The receiver operating characteristic curve (ROC) was drawn, and the area under the ROC curve (AUC) was used to evaluate the diagnostic value of miR-127 in patients with ARDS. Results. The serum level of miR-127 (10.15 ± 1.03) in the observation group was significantly higher than that in the control group (3.09 ± 0.62). And in the three subgroups of mild, moderate, and severe, the serum miR-127 level in the moderate group (10.43 ± 0.71) and the severe group miR-127 level (11.05 ± 1.26) were significantly higher than those in the mild group level (9.38 ± 1.24). Pearson correlation analysis showed that the serum miR-127 level was negatively correlated with PaO2/FiO2 (r = −0.715, P < 0.05 ), that is, the serum miR-127 level was positively correlated with the severity of ARDS patients. The area under the curve (AUC) of the diagnostic value of serum miR-127 for ARDS was 0.732 (95% CI 0.607–0.858). When the optimal cutoff value was 0.380, the sensitivity was 59.1% and the specificity was 78.6%, which suggested that miR-127 can be used as a marker for ARDS diagnosis. Conclusion. There is an increase in miR-127 levels in the serum of ARDS patients. The serum miR-127 level is positively correlated with the severity of ARDS. The higher the level of miR-127, the worse the condition of ARDS, which is positively correlated with the severity of the condition. It suggests that the serum miR-127 level is an important indicator for evaluating the severity of ARDS patients. It can be used as a molecular marker for clinical diagnosis of ARDS.
