Background::Bladder cancer, characterized by a high potential of tumor recurrence, has high lifelong monitoring and treatment costs. To date, tumor cells with intrinsic softness have been identified to function as cancer stem cells in several cancer types. Nonetheless, the existence of soft tumor cells in bladder tumors remains elusive. Thus, our study aimed to develop a microbarrier microfluidic chip to efficiently isolate deformable tumor cells from distinct types of bladder cancer cells.Methods::The stiffness of bladder cancer cells was determined by atomic force microscopy (AFM). The modified microfluidic chip was utilized to separate soft cells, and the 3D Matrigel culture system was to maintain the softness of tumor cells. Expression patterns of integrin β8 (ITGB8), protein kinase B (AKT), and mammalian target of rapamycin (mTOR) were determined by Western blotting. Double immunostaining was conducted to examine the interaction between F-actin and tripartite motif containing 59 (TRIM59). The stem-cell-like characteristics of soft cells were explored by colony formation assay and in vivo studies upon xenografted tumor models. Results::Using our newly designed microfluidic approach, we identified a small fraction of soft tumor cells in bladder cancer cells. More importantly, the existence of soft tumor cells was confirmed in clinical human bladder cancer specimens, in which the number of soft tumor cells was associated with tumor relapse. Furthermore, we demonstrated that the biomechanical stimuli arising from 3D Matrigel activated the F-actin/ITGB8/TRIM59/AKT/mTOR/glycolysis pathways to enhance the softness and tumorigenic capacity of tumor cells. Simultaneously, we detected a remarkable up-regulation in ITGB8, TRIM59, and phospho-AKT in clinical bladder recurrent tumors compared with their non-recurrent counterparts.Conclusions::The ITGB8/TRIM59/AKT/mTOR/glycolysis axis plays a crucial role in modulating tumor softness and stemness. Meanwhile, the soft tumor cells become more sensitive to chemotherapy after stiffening, that offers new insights for hampering tumor progression and recurrence.

Objective:To investigate the prognosis and influencing factors in critically ill surgical patients of different feeding intolerance trajectories.Methods:The retrospective cohort study was conducted. The clinical data of 354 critically ill surgical patients who were admitted to 69 medical centers in the Chinese Critical Care Nutrition Trials Group -NEED database from March 2018 to July 2019 were selected. There were 247 males and 107 females, aged 58(46,68)years. According to the trajectory model of feeding intolerance change, 354 patients were divided into 3 categories as feeding intolerance, decreased feeding intolerance, continuous feeding intolerance, including 164, 49, 141 cases respectively. Observation indicators: (1) general situations of patients of different feeding intolerance trajectories; (2) treatment of patients of different feeding intolerance trajectories; (3) survival of patients of different feeding intolerance trajectories; (4) analysis of pro-gnostic factors in critically ill surgical patients. Measurement data of normal distribution were expressed as Mean± SD, and one-way analysis of variance was used for comparison between groups. Measurement data of skewed distribution were expressed as M( Q1, Q3), and Kruskal-Wallis rank sum test was used for comparison between groups. Count data were expressed as absolute numbers or percentages, and chi-square test was used for comparison between groups. Ordinal data were compared using the Kruskal-Wallis rank sum test. Bonferroni correction was used for pairwise comparison. Group-based trajectory model was constructed according to Traj plug-in in Stata17.0 statistical software, and the optimal trajectory model was evaluated by Bayesian information criterion and average posterior probability parameter. The Kaplan-Meier method was used to draw the survival curve and calculate the survival rate, and Log-Rank test was used for survival analyses. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. Results:(1) General situations of patients of different feeding intolerance trajectories. Of 354 critically ill surgical patients, 257 cases underwent enteral nutrition and 97 cases underwent enteral plus parenteral nutrition. The acute physiological and chronic health score (APACHEII) was 17(13,21), and the sequential organ failure score (SOFA) was 6(5,8). The modified Critical Illness Nutritional risk score (mNUTRIC) was 4 (2,5), the number of complications was 2(1,3). There were 293, 55 and 6 patients with grade Ⅰ, grade Ⅱ and grade Ⅲ acute gastrointestinal injury (AGI), and there were 224, 17 and 61 patients who were treated with mechanical ventilation, continuous renal replacement therapy and vasoactive drugs, respectively. The incidence of feeding intolerance in 354 patients increased first and then decreased, reaching a peak of 25.42%(90/354) on the third day and 53.67%(190/354) within 7 days. Of 354 critically ill surgical patients, cases with no feeding intolerance, decreased feeding intolerance, continuous feeding intolerance had the APACHE Ⅱ as 16(12,20), 17(14,25), 18(13,22), mNUTRIC as 3(2,5), 4(3,6), 4(3,5), the number of complications as 2(1,2), 2(2,3), 2(2,3). There were 152, 27, 114 cases with grade Ⅰ AGI, 12, 22, 27 cases with grade Ⅱ-Ⅲ AGI, 95, 39, 90 cases with mechanical ventilation. There were significant differences in the above indicators among the three groups ( H=6.14, 13.11, 28.05, χ2=37.96, 7.65, P< 0.05). Further analysis showed that compared with patients with no feeding intolerance, patients with decreased feeding intolerance and continuous feeding intolerance had the higher number of complications and grade of AGI ( Z=60.32, 54.69, χ2=39.72, 9.52, P<0.05), patients with decreased feeding intolerance had the higher mNUTRIC scores and ratio of mechanical ventilation ( Z=53.41, χ2=7.59, P<0.05). (2) Treatment of patients of different feeding intolerance trajectories. Cases with prokinetic drugs use and post-pyloric feeding were 36, 13 of patients with no feeding intolerance, 25 and 10 of patients with decreased feeding intolerance, 46 and 19 of patients with continuous feeding intolerance, respectively, showing significant differences in the above indicators among the three groups ( χ2=15.76, 6.20, P<0.05). Further analysis showed that compared with patients with no feeding intolerance, patients with decreased feeding intolerance had higher ratio of prokinetic drugs use and ratio of post-pyloric feeding ( χ2=15.60, 6.10, P<0.05). (3) Survival of patients of different feeding intolerance trajectories. The 28-day overall survival rates of patients with no feeding intolerance, decreased feeding intolerance, and continued feeding intolerance were 96.96%, 95.92%, and 87.94%, respectively, showing a significant difference ( χ2=10.39, P<0.05). Further analysis showed a significant difference between patents with no feeding intolerance and patients with continuous feeding intolerance ( χ2=9.19, P<0.05). (4) Analysis of prognostic factors in critically ill surgical patients. Multivariate analysis showed that continuous feeding intolerance was an independent risk factor for 28-day death in critically ill surgical patients ( hazard ratio=3.92, 95% confidence interval as 1.43-10.79, P<0.05). Conclusion:For surgical critically ill patients, patients with continuous feeding intolerance have a higher 28-day mortality than patients with no feeding intolerance, and the continuous feeding intolerance is an independent risk factor for 28-day death in critically ill surgical patients.

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 effects of different parenteral nutrition on acute inflammatory response,immune cells and lipid metabolism in patients after pancreaticoduodenectomy.Methods Eighty patients after pancreaticoduodenectomy were divided into study group and control group,with 40 cases in each group.Structural fat emulsion was used in study group and medium/long chain fat emulsion in control group.The changes of acute inflammation,immune cells and lipid metabolism were compared between the two groups.Results (1)The levels of C-reactive protein (CRP) and serum prostaglandin E2 (PGE2) in the two groups were significantly higher on the first day after operation than those before operation.The difference between the two groups was statistically significant (P ＜ 0.05).The level of CRP and PGE2 decreased to the preoperative level on the seventh day after operation,but the decline rate in the study group was significantly faster than that in the control group (P ＜ 0.05).(2) The levels of CD3 +,CD4 +,CD8 +,CD4 +/CD8 + in the study group were significantly higher than those in the control group (P ＜ 0.05).(3) After 3-7 days of intravenous parenteral nutrition infusion,the blood lipid level was significantly lower in study group (P ＜ 0.05).Conclusion Structural fat emulsion alleviates the inflammatory reaction in patients after pancreaticoduodenectomy,promotes the recovery of immunity,significantly reduces the level of blood lipids.

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.

Objective: To study the expression of microRNA-100 (miR-100) in hepatocellular carcinoma (HCC) tissues and cells, and further explore the function of miR-100 on invasion and metastasis of HCC. Methods: A total of 50 patients with HCC from December 2016 to October 2018 in Department of Hepatobiliary Pancreatic Surgery, Henan Provincial People's Hospital were selected, including 32 males and 18 females, aged 20~78 years. PCR was used to detect the expression of miR-100 in HCC tissues, adjacent tissues and HCC cells. HCC cells were transfected with miR-100 sequence, inhibition sequence and corresponding negative control sequence to detect the migration and invasion ability of HCC cells after transfection. Results: The expression of miR-100 was lowest in SMMC-7721 and MHCC-97H. The relative expression level of miR-100 in HCC tissues was significantly lower than that in normal adjacent liver tissues [(0.39±0.03) vs. (0.56±0.06)], and the difference was statistically significant (P<0.05). Compared with the negative control HCC cells, the migration and invasion of HCC cells with overexpression of miR-100 decreased, while the inhibition of miR-100 expression increased the migration and invasion of HCC cells. Conclusions The expression of miR-100 is low in human HCC tissues and cells. miR-100 inhibits the invasion and migration of HCC cells and plays an important role in the occurrence and development of HCC.

Objective To analyze the relationship between the level of microRNA-29b in circulation and left ventricular hypertrophy in hypertensive patients.Methods A total of 240 subjects from Henan Province People's Hospital from June 2015 to June 2018 were included in the present study.Among them,160 were hospitalized patients,and were divided into two groups.Patients with simple hypertension and had no left ventricular hypertrophy (80 cases) were in the simple hypertension group (HBP-NLVH),and patients with hypertension combined with left ventricular hypertrophy (80 cases) were in the high blood pressure with left ventricular hypertrophy group (HBP-LVH).Normal control subjects (80 cases) were those with no hypertension and randomly selected from the medical center of Henan Province People's Hospital.Serum microRNA-29b expressions were detected by real time fluorescence quantitative PCR.The thickness of interventricular septum (IVSD) and left ventricular posterior wall thickness (LVPWD) were measured by echocardiography.Results Compared with the normal control group (1.95±0.79),the relative expression of microRNA-29b in the patients both in the HBP-NLVH group (2.67±0.92) and the HBP-LVH group (5.12 ± 1.23) was up-regulated,and the difference between normal control and patients was statistically significant (P＜0.05).In patients,the microRNA-29b level in the HBP-LVH group was significantly higher than that in the HBP-NLVH group (P＜0.05).The expression level of microRNA-29b was positively correlated with IVSD (r=0.71,P＜0.05) and LVPWD (r=0.74,P＜0.05),respectively.The sensitivity and specificity of serum microRNA-29b levels in the diagnosis of left ventricular hypertrophy in hypertension patients were 96.8％ and 91.3％,respectively.Conclusion Serum microRNA-29b level is elevated in hypertensive patients with left ventricular hypertrophy,and is positively correlated with left ventricular hypertrophy.The circulation microRNA-29b might be a useful biomarker with prognostic value in left ventricular hypertrophy in hypertension patients.
