Objective:To investigate the role of LncRNA-TUG1 in the injury of intestinal epithelial cells induced by lipopolysaccharide (LPS).Methods:LPS was used to treat HIEC-6 human intestinal epithelial cells for 24 h to construct a sepsis injury model. Whole transcriptome RNA sequencing was used to analyze the expression changes of mRNA, microRNA and lncRNA in HIEC-6 cells after LPS treatment. Real-time fluorescence quantitative (qRT-PCR) and Western blot was performed to detect the expression changes of lncRNA-TUG1, microRNA-132-3p (miR-132-3p), SIRT1 mRNA and SIRT1 protein in HIEC-6 cells after LPS treatment. The expression levels of LncRNA-TUG1, miR-132-3p and SIRT1 were artificially changed by in vitro transfection. qRT-PCR and Western blot were used to confirm the regulatory effect of lncRNA-TUG1 on microRNA-132-3p and SIRT1. CCK-8 and flow cytometry were used to analyze the effects of LncRNA-TUG1, miR-132-3p and SIRT1 on the proliferation and apoptosis of HIEC-6 cells. The dual luciferase report analysis was used to verify the targeting relationship between LncRNA-TUG1, miR-132-3p and SIRT1. Statistical analysis was performed using SPSS 17.0, and differences between the two groups were compared using independent sample t test. Results:RNA sequencing results showed that the expressions of lncRNA-TUG1 and SIRT1 were decreased in HIEC-6 cells after LPS treatment ( t=3.26, P<0.05 and t=2.55, P<0.05), but the expression of miR-132-3p was increased ( t=4.12, P<0.05). In vitro cell experiments, the expression of lncRNA-TUG1 and SIRT1 were decreased in HIEC-6 cells treated with LPS ( t=5.69, P<0.05 and t=5.712, P<0.05), while the expression of miR-132-3p was increased ( t=3.88, P<0.05). Overexpression of lncRNA-TUG1 increased the proliferation rate ( t=6.55, P<0.05) and decreased the apoptosis rate ( t=3.94, P<0.05) of LPS-treated cells. Upregulation of lncRNA-TUG1 decreased the expression of miR-132-3p ( t=4.66, P<0.05), and increased the mRNA and protein levels of SIRT1 ( t=3.91, P<0.05). Transfection of miR-132-3P mimic could inhibit the mRNA ( t=4.08, P<0.05) and protein levels of SIRT1. In LPS-treated cells, the cells co-transfected with miR-132-3pmimic and siRNA-SIRT1 had a lower proliferation rate ( t=4.55, P<0.05 and t=5.67, P<0.05) and a higher apoptosis rate ( t=3.90, P<0.05 and t=4.22, P<0.05) than those transfected with only pcDNA3.1-lncRNA-TUG. Conclusions:lncRNA-TUG1 may act as a ceRNA to regulate miR-132-3p/SIRT1, therefore alleviating HIEC-6 cell injury caused by LPS. Intervention of lncRNA-TUG1/miR-132-3p/SIRT1 regulatory pathway may become a potential strategy to prevent sepsis-induced intestinal mucosal damage.

Objective:To study the miR-100 expression levels in the tissues of hepatocellular carcinoma patients, and to further explore the correlation between miR-100 and the invasion and metastasis of hepatocellular carcinoma cells and its effect on patients’ prognostic survival.Methods:Clinicopathological data of 70 cases that underwent hepatectomy from December 2013 to December 2016 in the Department of Hepatobiliary and Pancreatic Surgery of Henan Provincial People's Hospital were retrospectively analyzed. Real-time fluorescent quantitative PCR was used to detect the different miR-100 expression levels in cancerous and adjacent tissues. The expression of miR-100 with different clinicopathological features was compared, and the prognostic factors of patients with hepatocellular carcinoma were comprehensively analyzed. The correlation between miR-100 and patients’ clinicopathological features was tested by χ 2. Kaplan-Meier method was used to draw the survival curve. Log-rank test was used to examine the survival rate difference in each subgroup. Cox regression model was used to analyze the multivariate prognosis. Results:miR-100 expression was down-regulated to a different degree in hepatocellular carcinoma tissues than the corresponding adjacent tissues. Among them, the down-regulated expression of miR-100 in hepatocellular carcinoma tissues accounted for 82.9% (58/70, P < 0.05) of all cases when compared to corresponding paracancerous tissues. miR-100 expression level was significantly correlated to high Edmondson’s grade, high TNM stage and intrahepatic metastasis ( P < 0.05). The overall survival time of miR-100 positive expression was significantly higher than that of miR-100 negative expression (Log-rank χ 2 = 8.257, P < 0.05). Univariate survival analysis results revealed that the miR-100 expression level, tumor size, TNM stage, Edmondson’s grade, and presence or absence of venous tumor thrombosis had a poor prognosis ( P < 0.05). Cox multivariate regression analysis showed that the tumor size, Edmondson’s grade, and miR-100 expression level were independent factors affecting the prognostic survival in hepatocellular carcinoma patients. In addition, patients with low positive expression rate of miR-100, large tumors and high Edmondson’s grade had a poor prognosis. Conclusion:The level of miR-100 expression in hepatocellular carcinoma cells is low, so it is closely related to the invasion and metastasis and affects the prognostic survival of hepatocellular carcinoma patients.
