Value of triglyceride-glucose index and body mass index in predicting nonalcoholic fatty liver disease in patients with type 2 diabetes mellitus / 临床肝胆病杂志

Objective To investigate the value of triglyceride-glucose index (TyG) and body mass index (BMI) in predicting nonalcoholic fatty liver disease (NAFLD) in type 2 diabetes mellitus (T2DM). Methods A retrospective analysis was performed for the clinical data of 349 patients with T2DM who were treated in Shengjing Hospital of China Medical University from May 2020 to July 2021, and according to the presence or absence of NAFLD, they were divided into T2DM+NAFLD group with 213 patients and simple T2DM group with 136 patients. The t -test or the Mann Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. A logistic regression analysis was used to investigate the association of TyG and BMI with T2DM+NAFLD, and the receiver operating characteristic (ROC) curve was plotted to evaluate the prediction efficiency of TyG alone, BMI alone, and TYG combined with BMI for NAFLD in T2DM. The Kappa coefficient was used to analyze the consistency of prediction results. Results Compared with the simple T2DM group, the T2DM+NAFLD group had significantly higher BMI, diastolic pressure, fasting blood glucose, HbA1c, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, triglyceride, total cholesterol, low-density lipoprotein cholesterol, and TyG (all P 0.05). The logistic regression analysis showed that TyG (odds ratio [ OR ]=6.513, 95% confidence interval [ CI ]: 1.884-22.517, P < 0.001) and BMI ( OR =1.369, 95% CI : 1.191-1.575, P < 0.001) were independent risk factors for NAFLD in T2DM. The ROC curve analysis showed that TyG had an area under the ROC curve (AUC) of 0.875 in predicting NAFLD in T2DM, with a sensitivity of 80.3%, a specificity of 80.1%, a positive predictive value of 86.36%, and a negative predictive value of 72.19% at the optimal cut-off value of 9.41; BMI had an AUC of 0.787, with a sensitivity of 78.9%, a specificity of 64.0%, a positive predictive value of 77.36%, and a negative predictive value of 64.23% at the optimal cut-off value of 24.22; TyG combined with BMI had an AUC of 0.910, a sensitivity of 81.2%, a specificity of 88.2%, a positive predictive value of 91.53%, and a negative predictive value of 75.00% in predicting NAFLD in T2DM. TyG alone, BMI alone, and TyG combined with BMI had a Kappa coefficient of 0.592, 0.416, and 0.673, respectively, in predicting NAFLD in T2DM. Conclusion TyG and BMI can be used to predict the onset of NAFLD in T2DM, and the combination of TyG and BMI can improve the predictive value.

Value of red blood cell distribution width-to-platelet ratio in evaluating metabolic-associated fatty liver disease and liver cirrhosis / 临床肝胆病杂志

Objective To investigate the clinical significance of red blood cell distribution width-to-platelet ratio (RPR index) in evaluating the severity of metabolic-associated fatty liver disease and predicting fatty liver-associated cirrhosis. Methods A total of 192 patients with metabolic-associated fatty liver disease and 210 patients with fatty liver-associated cirrhosis who were admitted to Shengjing Hospital of China Medical University from January 2019 to June 2020 were enrolled as group A and group B, respectively, and 206 individuals who underwent physical examination in our hospital during the same period of time were enrolled as control group (group C). All subjects underwent general measurement, blood cell analysis, blood biochemical test, and abdominal CT examination, and related formulas were used to calculate RPR, aspartate aminotransferase-to-platelet ratio index (APRI), and fibrosis-4 (FIB-4) index. A one-way analysis of variance was used for comparison of continuous data with homogeneity of variance between groups, and the SNK method was used for comparison between two groups; the Kruskal-Wallis H test was used for comparison of continuous data with heterogeneity of variance between groups, and the Mann-Whitney U test was used for comparison between two groups; the chi-square test was used for comparison of categorical data between groups; the receiver operating characteristic (ROC) curve was used to analyze the accuracy of the prediction of liver cirrhosis. Results There were significant differences in red blood cell distribution width-standard deviation, albumin, creatinine, body mass index, RPR, and APRI between any two groups (all P < 0.001), and there were significant differences in white blood cell count, platelet count, alanine aminotransferase, aspartate aminotransferase, direct bilirubin, blood urea nitrogen, and FIB-4 between group A and group B (all P < 0.05). There were significant differences in waist circumference and fasting blood glucose between groups A and B and between groups A and C (all P < 0.001). There was a significant difference in RPR between any two groups of the mild, moderate, and severe metabolic-associated fatty liver disease groups (all P < 0.05). In terms of diagnostic efficiency, the three noninvasive models RPR, APRI, and FIB-4 had an area under the ROC curve of 0.932, 0.815, and 0.877, respectively, in predicting fatty liver-associated cirrhosis. Conclusion There is a difference in RPR index between different stages of liver disease, and RPR index gradually increases with the aggravation of metabolic-associated fatty liver disease. RPR index has a higher value than APRI and FIB-4 in the warning of fatty liver-associated cirrhosis.

The influence of survivin shRNA on the cell cycle and the invasion of SW480 cells of colorectal carcinoma.

BACKGROUND: The objective was to understand the influence of Survivin plasmid with short hairpin RNA (shRNA) on the cell cycle, invasion, and the silencing effect of Survivin gene in the SW480 cell of colorectal carcinoma. METHODS: A eukaryotic expression vector, PGCH1/Survivin shRNA, a segment sequence of Survivin as target, was created and transfected into colorectal carcinoma cell line SW480 by the non-lipid method. The influence on the Survivin protein was analyzed by Western blotting, while the cell cycle, cell apoptosis were analyzed by flow cytometry, and invasion of the cell was analyzed by Transwell's chamber method. RESULTS: After the transfection of PGCH1/Survivin shRNA, the expression of Survivin protein in SW480 cells was dramatically decreased by 60.68%, in which the cells were stopped at G2/M phase, even though no apoptosis was detected. The number of transmembranous cells of the experimental group, negative control group, and blank control group were 14.46 +/- 2.11, 25.12 +/- 8.37, and 25.86 +/- 7.45, respectively (P <0.05). CONCLUSION: Survivin shRNA could significantly reduce the expression of Survivin protein and invasion of SW480 cells. Changes in cell cycle were observed, but no apoptosis was induced.

Dysregulated expression of stem cell factor Bmi1 in precancerous lesions of the gastrointestinal tract.

PURPOSE: It is important to identify the definitive molecular switches involved in the malignant transformation of premalignant tissues. Cellular senescence is a specific characteristic of precancerous tissues, but not of cancers, which might reflect tumorigenesis-protecting mechanisms in premalignant lesions. Polycomb protein Bmi1, which is a potent negative regulator of the p16INK4 gene, suppresses senescence in primary cells and is overexpressed in various cancers. We hypothesized that Bmi1 expression would also be dysregulated in precancerous lesions in human digestive precancerous tissues. EXPERIMENTAL DESIGN: Bmi1 expression was investigated in cancerous and precancerous tissues of the digestive tract. The expression of p16, beta-catenin, and Gli1 and the in vivo methylation status of the p16 gene were also analyzed in serial sections of colonic precancerous lesions. RESULTS: Bmi1 was clearly overexpressed across a broad spectrum of gastrointestinal cancers, and the expression of Bmi1 increased in a manner that reflected the pathologic malignant features of precancerous colonic tissues (low-grade dysplasia, 12.9 +/- 2.0%; high-grade dysplasia, 82.9 +/- 1.6%; cancer, 87.5 +/- 2.4%). p16 was also strongly expressed in high-grade dysplasia, but not in cancers. p16 promoter methylation was detected only in some Bmi1-positive neoplastic cells. CONCLUSIONS: Bmi1 overexpression was correlated with the malignant grades of human digestive precancerous tissues, which suggests that advanced Bmi1 dysregulation might predict malignant progression. The abnormal Bmi1 expression might link to malignant transformation via the disturbance of orderly histone modification.
