Background: Growing evidence has indicated that long non-coding RNAs (lncRNAs) are important regulators of pathological and physiological processes through various mechanisms. However, the signature of lncRNA expression and the possible roles of lncRNAs in spinal cord injury (SCI) rat neurogenic bladder (NB) have not been comprehensively explored. In this study, the expression profiles of lncRNAs and mRNAs were explored in the bladder tissue of SCI rats using next-generation sequencing (NGS).Methods: Twenty female Wistar rats were randomly divided into SCI 1-3 and normal control (NC) groups.The spinal cord was completely transected at the T9-T10 level to establish the SCI model. Bladder tissues were collected on days 7, 14, and 28 after the operation. The expression profiles of lncRNAs were detected by NGS. Differentially expressed lncRNAs (DELs) were chosen for qRT-PCR verification to validate the RNA sequencing results. The functions of the predicted target genes were then evaluated using Gene Ontology (GO) enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis.Results: Compared with the NC group, the SCI 1-3 groups had 468, 117, and 408 DELs [fold change (FC)
Background: Dyslipidemia contributes to the development of nephrolithiasis in adults; however its relationship to urolithiasis in children remains debatable, and will be clarified in the present work. Methods: A case-control study was performed involving 58 pediatric patients diagnosed with upper urinary tract stones as well as 351 controls. Age, gender, body mass index (BMI), serum calcium, serum uric acid, blood glucose, blood lipids, and compositions of stones were compared. Results: According to the univariate analysis, uric acid was higher (P < 0.01) but serum calcium lower in the stone group than the control (P < 0.05). As for the blood lipids, non-high-density lipoprotein cholesterol (non-HDL-c) was significantly higher in the stone group as compared to the control (P < 0.01), while total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol did not show statistical difference between the two groups. In the multivariate analysis, only non-HDL-c and serum uric acid were increased in the stone group (P = 0.003 and P = 0.008). In the stone compositions' analysis, serum uric acid and non-HDL-c were associated with percentage of uric acid and pure calcium oxalate stones, respectively. Conclusion: Non-high-density lipoprotein cholesterol may act as a lipid risk factor for urolithiasis in children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
