The lesions were located in the esophagus (n=232), stomach (n=1 225), duodenum (n=9), colon (n=152) and rectum (n=181). There were 500 patients (508 ESD operations) with underlying diseases, and 1 188 patients without underlying diseases. Most patients with lesions at stomach, esophagus and colon rectum, and these patients were divided into four age groups <45 years (n=202), 4559 years (n=643), 6074 years (n=744), and ≥75 years (n=99). The postoperative complications rates of ESD in different lesions among four age groups were compared. Chi-square test was performed for statistical analysis. \u0000 \u0000 \u0000Results \u0000From 2011 to 2017, the complication rates after ESD were 20.0% (8/40), 18.3% (21/115), 15.9% (35/220), 10.7% (31/291), 11.3% (40/355), 10.7% (41/384) and 10.7% (42/394), respectively, and the difference was not statistically significant (χ2=10.432, P=0.064). Further analysis revealed that the complication rates after ESD between 2011 and 2013 was significantly higher than that between 2014 and 2017 (17.1%, 64/375 vs. 10.8%, 154/1 424); and the difference was statistically significant (χ2=10.895, P<0.01). The complication rates of patients with lesions in the esophagus of<45 years group, 4559 years group, 6074 years group and ≥75 years group were 4.5% (1/22), 23.6% (17/72), 24.4% (31/127) and five cases (totally 11 cases). The complication rates of patients with lesions in the stomach of<45 years group, 4559 years group, 6074 years group and ≥75 years group were 19.2% (28/146), 14.2% (68/479), 15.8% (85/539) and 16.4% (10/61). The complication rates of lesions in the colon of<45 years group, 4559 years group, 6074 years group and ≥75 years group were one case (totally 12 cases), 3.4% (2/58), 10.9% (7/64) and five cases (totally 18 cases), respectively.The complication rates of lesions in the rectum of <45 years group, 4559 years group, 6074 years group and ≥75 years group were 3.3% (1/30), 10.4% (7/67), 19.4% (14/72) and two cases (totally 12 cases), respectively. There were significant differences in complication rates between different age groups with lesions in the esophagus (χ2=10.894, P=0.012) and the colon (χ2=13.540, P=0.004).

The tumor tissues and corresponding paracancerous tissues (negative control) were also collected. The expression of circ-VIM in the colorectal cancer tissues was determined by quantitative real-time polymerase chain reaction (qRT-PCR). The proliferation of HCT-116 and HT29 colorectal cancer cells was detected by cell counting kit-8 assay. The ratio of apoptosis of HCT-116 and HT29 cells was measured by annexin Ⅴ/propidium iodide double staining assay. The mitochondrial membrane potential of HCT-116 and HT29 cells was examined by 5, 5′, 6, 6′-tetrachloro-1, 1′, 3, 3′-tetraethyl-imidacarbocyanine iodide (JC-1) assay.

Meanwhile, the obtained differentially expressed genes together with gene expression data of 81 ESCC patients from the cancer genome atlas (TCGA) and clinical data were analyzed by WGCNA to set up co-expression networks including mRNA and microRNA (miRNA). The expression of miRNA in ESCC tissues and paracancerous tissues was examined by quantitative real-time polymerase chain reaction (RT-PCR). And the expression of target protein Kruppel like factor 4 (KLF4) and desmocollin 2 (DSC2) were detected by immunohistochemistry. After ESCC cell line ECA-109 cells were transfected with miRNA-92b-3p mimic, cell cycle was tested by flow cytometry, the cell invasion and migration ability was measured by Transwell chamber assay and scratch-wound assay. The expression of KLF4 and DSC2 was observed by confocal laser scanning microscopy and Western blotting.The target genes were verified by luciferase assay. T-test, rank sum test, chi-square test and Pearson correlation analysis were performed for statistical analysis. \u0000 \u0000 \u0000Results \u0000A total of 4 023 differential expression gene (DEG) and 328 differential expression miRNA (DEM) were screened and 11 gene modules were set up by WGCNA. Among them, the brown modules were negatively associated with tumor grade and T stage (r=-0.340 and -0.268, P=0.002 and 0.016). Meanwhile, has-miR-92b and the potential target genes KLF4 and DSC2 were all in the brown module. Furthermore, the results of RT-PCR showed the expression of miRNA-92b-3p in ESCC tissues was higher than that in paracancerous tissues (3.052(1.652, 5.371) vs. 0.985(0.558, 2.032)), and the difference was statistically significant (Z=-4.021, P<0.01). The results of immunohistochemistry demonstrated that the positive rates of KLF4 and DSC2 in ESCC tissues were 43.3%(13/30) and 20.0%(6/30), respectively, which were lower than those of paracancerous tissues (70.0%(21/30) and 63.3%(19/30)), and the differences were statistically significant (χ2=4.344 and 1.589, both P<0.05). After ECA-109 cells were transfected with miRNA-92b-3p mimics, the percentage of cells at G0/G1 phase decreased ((63.71±2.83)% vs. (54.62±4.00)%) and the percentage of cells at the S phase and G2/M phase increased ((31.81±2.88)% vs. (41.20%±2.87)%, and (3.87±1.75)% vs. (8.10±1.71)%, respectively), and the differences were statistically significant (t=3.215, 4.000 and 2.998; P=0.032, 0.016 and 0.040).

Serum samples were examined by liquid chromatography-mass spectrometry (LC-MS) for metabolomics analysis. Orthogonal partial least square (OPLS) was performed for raw data analysis to obtain the differentially expressed metabolites between two groups. The first 15 cases of each group were taken as training samples and the left as validation samples. The model was established using logistic regression via stepwise differentially expressed metabolites and clinical data input in training samples.

The differentially expressed metabolites identified in negative ion mode were C16 sphingosine-1-phosphate, keto palmitic acid, isoleucine, N-succinyl-L-diaminopimelic acid and uridine.
