Objective To explore the protective effect and mechanism of miR-202-5p on acute respiratory distress syndrome(ARDS)-induced lung injury in neonatal rats.Methods Sixty newborn SD rats were randomly divided into six groups:the control group(intraperi-toneal injection of normal saline by tail vein),ARDS group(ARDS model established via intraperitoneal injection of 4 mg/kg lipopolysac-charide by tail vein),ARDS+miR-NC group(ARDS rats receiving 2 mg/kg miR-NC via tail vein injection once every 4 h,with intervention for 12 h),ARDS+miR-202-5p group(ARDS rats receiving 2 mg/kg miR-202-5p via tail vein injection once every 4 h,with intervention for 12 h),ARDS+miR-202-5p+ov-NC group,and ARDS+miR-202-5p+ov-ROCK1 group(ARDS rats receiving 2 mg/kg miR-202-5p once every 4 h,with intervention for 12 h;with 6 × 108 plaque-forming units control or overexpression ROCK adenovirus administered via tail vein 3 days before lipopolysaccharide injection).Real-time quantitative PCR was employed to measure miR-202-5p and ROCK1 mRNA expression in rat lung tissue.Hematoxylin and eosin staining was performed to assess pathological lung injury.The lung tissue wet-to-dry weight ratio was determined to evaluate pulmonary edema.Western blotting was utilized to analyze ROCK1,Toll-like receptor 4(TLR4),phosphorylated-nuclear factor κB(p-NF-κB)p65,and phosphorylated-inhibitor of nuclear factor-κBα(p-IκBα)protein expression in lung tissue.The interaction between miR-202-5p and ROCK1 was validated using dual-luciferase reporter gene experiments.Results miR-202-5p expression was significantly down-regulated in ARDS rat lung tissue,while overexpression of miR-202-5p ameliorated pathological injury and pulmonary edema in ARDS rats.ROCK1 mRNA was upregulated in ARDS rat lung tissue;however,overexpression of miR-202-5p decreased the expression of ROCK1 in lung tissue of ARDS rats,while overexpression of ROCK1 reversed the protective effect of overexpression of miR-202-5p on lung injury in ARDS rats.Furthermore,miR-202-5p overexpression suppressed TLR4,p-NF-κB p65,and p-IκBα protein expression in ARDS rat lung tissue,an effect that was reversed by ROCK1 overexpression.Dual-luciferase reporter gene experiments confirmed that miR-202-5p directly targets ROCK1 mRNA 3'UTR.Conclusion miR-202-5p ameliorates ARDS-in-duced lung injury in neonatal rats through targeted suppression of ROCK1 expression,with the underlying mechanism potentially involving inhibition of ROCK1-mediated TLR4/NF-κB signaling pathway activation.

Analyzing the influence of mixed emotional factors on false memory through brain function network is helpful to further explore the nature of brain memory. In this study, Deese-Roediger-Mc-Dermott (DRM) paradigm electroencephalogram (EEG) experiment was designed with mixed emotional memory materials, and different kinds of music were used to induce positive, calm and negative emotions of three groups of subjects. For the obtained false memory EEG signals, standardized low resolution brain electromagnetic tomography algorithm (sLORETA) was applied in the source localization, and then the functional network of cerebral cortex was built and analyzed. The results show that the positive group has the most false memories [(83.3 ± 6.8)%], the prefrontal lobe and left temporal lobe are activated, and the degree of activation and the density of brain network are significantly larger than those of the calm group and the negative group. In the calm group, the posterior prefrontal lobe and temporal lobe are activated, and the collectivization degree and the information transmission rate of brain network are larger than those of the positive and negative groups. The negative group has the least false memories [(73.3 ± 2.2)%], and the prefrontal lobe and right temporal lobe are activated. The brain network is the sparsest in the negative group, the degree of centralization is significantly larger than that of the calm group, but the collectivization degree and the information transmission rate of brain network are smaller than the positive group. The results show that the brain is stimulated by positive emotions, so more brain resources are used to memorize and associate words, which increases false memory. The activity of the brain is inhibited by negative emotions, which hinders the brain's memory and association of words and reduces false memory.
