Profound Effect of Pulmonary Surfactant on the Treatment of Preterm Infants with Respiratory Distress Syndrome. CONTRAST MEDIA & MOLECULAR IMAGING 2022; 2022:4166994. [PMID: 36262981 PMCID: PMC9550487 DOI: 10.1155/2022/4166994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 08/24/2022] [Accepted: 09/07/2022] [Indexed: 01/26/2023]
Abstract
Inherited diseases caused by dysfunction of pulmonary surfactant metabolism or surfactant dysfunction have recently been considered the underlying causes of neonatal and pediatric respiratory diseases. Respiratory distress syndrome in premature infants is a common respiratory disease in pediatrics. It is caused by underdeveloped lungs in infants and a lack of active substances on the surface of the alveoli, which leads to insufficiency of lung function, which can lead to difficulty breathing, increased heart rate, facial bruising, and more. Neonatal Respiratory Distress Syndrome is a very dangerous disease with a high mortality rate and a great threat to children's lives and health. Therefore, enough attention and treatment should be caused in clinical practice. Natural pulmonary surfactant (PS) has achieved positive effects in the treatment of neonatal respiratory distress syndrome (RDS), reducing neonatal mortality, the application of mechanical ventilation, and the occurrence of late complications. To further explore the role of pulmonary surfactants in the treatment of neonatal respiratory distress syndrome, to analyze the best time to use PS to prevent RDS, this paper has selected premature infants with RDS received by the neonatal department of a hospital in a province from March 2019 to October 2020 to compare the efficacy of pulmonary surfactant (PS) in preterm infants with respiratory distress syndrome (RDS). The experiment has found that the average mechanical ventilation time (5.1 d) and oxygen therapy time (7.3 d) in the early group are shorter than the average mechanical ventilation time (6.4 d) and oxygen therapy time (10.6 d) in the late group. It has been demonstrated that early administration of pulmonary surfactant (PS) therapy is of great help in improving respiratory distress syndrome in premature infants.

Abstract
Supplemental digital content is available in the text. Chest radiography is the primary imaging modality used for the assessment of neonatal respiratory distress syndrome (NRDS) in newborns. However, excessively exposing a growing neonate to harmful ionizing radiation may have long-term consequences. Some studies have shown that lung ultrasound (LUS) is helpful in the diagnosis of NRDS. A comprehensive search was carried out using PubMed, Embase, and the Cochrane Library to identify studies in which newborns with clinically suspected NRDS were assessed by LUS. Two investigators independently screened the literature and extracted the data. Any discrepancies were resolved via discussion with the senior author. Study quality was assessed by the Quality Assessment of Diagnostic Accuracy Studies 2 tool, and pooled sensitivity and specificity of various LUS findings for diagnosing NRDS were determined. Summary receiver operating characteristic curve was used to assess the overall performance of LUS. Ten studies with a total of 887 neonates were included in this meta-analysis. There was significant heterogeneity across the included studies. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio for the diagnosis of NRDS using LUS were 0.92 (95% confidence interval [CI], 0.89–0.94), 0.95 (95% CI, 0.93–0.97), 20.23 (95% CI, 8.54–47.92), 0.07 (95% CI, 0.03–0.14), and 455.30 (95% CI, 153.01–1354.79), respectively. Furthermore, the summary receiver operating characteristic area under the curve was calculated to be 0.9888. The main LUS characteristics of NRDS include bilateral white lung, pleural line abnormalities, and lung consolidation. In summary, LUS is a highly valuable diagnostic technology that complements chest radiography in the diagnosis and follow-up monitoring of NRDS.

Abstract
BACKGROUND The study of genetic polymorphisms of surfactant-lipids related genes can help to understand individual variability in the susceptibility to development of pulmonary pathologies. The purpose of this study was to evaluate the association of polymorphisms of surfactant-lipids related genes (LPCAT1, CHPT1 and PCYT1B) with the risk/severity of respiratory distress syndrome (RDS) in preterm neonates among the Chinese Han population in Southern China. METHODS Four hundred and forty-six preterm neonates were enrolled in a case-control study. Six polymorphisms of 3 genes were analyzed by PCR amplification of genomic DNA and genotyping was performed using an improved multiplex ligation detection reaction (iMLDR) technique based on LDR. RESULTS The GG genotype and G allele of LPCAT1-rs9728 were found less frequently in the RDS group than in the controls (11.5% vs. 22.0% and 38.3% vs. 48.2%, respectively) (p < 0.05). CONCLUSION This report is the first study to evaluate a direct genetic association between polymorphisms of LPCAT1 and RDS development in Chinese Han preterm infants. Our study raises the possibility that a genetic variation of LPCAT1 could be implicated in the pathophysiology of RDS in preterm neonates. GG genotype and G allele of rs9728 are protective factors for the development of RDS in preterm infants.

Abstract
Background In addition to the increasing evidence for a molecular mechanism of rho kinase 1 (ROCK1) in Alzheimer's disease (AD), there are several published studies regarding the relationship between ROCK1 gene polymorphisms and neurological diseases. However, it is unknown whether there is an association between the polymorphisms of ROCK1 and AD. We sought to identify the potential association between ROCK1 gene polymorphisms and AD in the Chinese Han population. Methods A total of 295 patients with AD and 206 healthy controls from multiple centers were enrolled in this study. Three single-nucleotide polymorphisms (SNPs) (rs35996865, rs11873284, and rs2127958) in ROCK1 gene were analyzed using Sanger sequencing. Results We did not find any significant differences between AD and control groups with regards to the frequency of these three ROCK1 polymorphisms. Further, the three SNP genotype frequencies and allele frequencies did not show significant differences between patients of AD and controls in APOE4-stratified subjects (P>0.01). Additionally, the three SNPs did not show significant differences even when adopting a four-inheritance model by logistic regression. Conclusions This is the first multicenter pilot study to evaluate the contribution of ROCK1 genetic variance to AD risk. Our data demonstrated that the ROCK1 gene may not influence the risk of AD by interacting with APOE among Chinese Han people.

Abstract
The effect of CASZI on bronchopulmonary development in neonatal rats was investigated. Forty SD rats were randomly divided into the control group (n=20) and the experimental group (n=20) using a random number table. The experimental group was treated with hyperoxia to establish the bronchopulmonary dysplasia (BPD) model, while the control group received no treatment. At 14 days of experiment, rats in each group were treated, and lung tissues were taken for hematoxylin and eosin (H&E) staining. Radial alveolar count (RAC) and morphological changes in lung tissues were observed under a microscope, and the thickness of respiratory membrane was detected via IPP6 image. Reverse transcription-polymerase chain reaction (RT-PCR) and western blotting were used to detect the expression levels of CASZI, Rho kinase, RhoA and ET-A receptor in lung tissues. There were no obviously pathological changes in lung tissues of neonatal rats in the control group, while BPD could be seen in lung tissue structures of neonatal rats in the experimental group. RAC in experimental group was significantly lower than that in the control group (P<0.05), and the thickness of respiratory membrane was significantly higher than that in the control group (P<0.05). CASZI mRNA expression level in the experimental group was significantly lower than that in control group (P<0.05), and Rho kinase, RhoA and ET-A receptor mRNA expression levels were significantly higher than those in the control group (P<0.05). CASZI protein expression level in the experimental group was significantly lower than that in the control group (P<0.05), and the Rho kinase, RhoA and ET-A receptor protein expression levels were significantly higher than those in the control group (P<0.05). In conclusion, CASZI expression was downregulated during the development of BPD. CASZI downregulation may have an effect on the pulmonary microvascular regeneration through RhoA/ROCK signaling pathway, thus participating in the pathogenesis of BPD.
