Objective To analyze the mechanism of aspirin against colorectal cancer(CRC)by bioinformatic analysis. Methods DrugBank 5.1.5 was used to identify direct protein targets (DPTs) of aspirin. The protein-protein interaction (PPI) network of DPTs was constructed and involved signaling pathways were analyzed. CRC-associated gene expression datasets were downloaded from GEO database, and the top twenty differentially expressed genes with the highest degree were screened out as Hub genes. Common genes between the genes associated with the DPTs and the Hub genes of CRC were the potential targets of aspirin against CRC. The potential targets in TCGA database colon adenocarcinoma (COAD) samples were examined. GO functional enrichment analysis and KEGG signaling pathway analysis of the potential targets were performed. The potential targets of aspirin against CRC cells were verified by reverse transcription-polymerase chain reaction (RT-PCR) and western blot (WB). Results Eleven DPTs of aspirin were identified in DrugBank 5.1.5. KEGG signaling pathway showed that 6 genes (EDNRA, IKBKB, NFKB2, NFKBIA, PTGS2, TP53) were associated with the occurrence and development of CRC. By intersecting 20 Hub genes of CRC with genes associated with the DPTs of aspirin, it was found that 5 genes (CDK1, AURKA, CCNB1, MAD2L1, TPX2) might be the potential targets of aspirin against CRC. They were all up-regulated in TCGA-COAD samples, and the gene functions were mainly enriched in cell cycle regulation. The results of RT-PCR and WB showed that aspirin could down-regulate the mRNA and protein expression levels of CDK1, AURKA, CCNB1, MAD2L1 and TPX2 in human colon cancer cells respectively. Conclusion CDK1, AURKA, CCNB1, MAD2L1 and TPX2 could be potential targets of aspirin against CRC by affecting the progress of cell cycle regulation.

Objective To evaluate the value of neutrophil-lymphocyte ratio (NLR) in the chemotherapy curative effect and prognosis of patients with advanced colorectal cancer (CRC). Methods Retrospective collection of clinical data from 50 patients with advanced unresectable colorectal cancer who received oxaliplatin-based standard first-line chemotherapy between January 2016 and April 2019. Chemotherapy curative effect was evaluated following 2 chemotherapy cycles. Calculation of neutrophil to lymphocyte ratio (NLR) based on pre-chemotherapy hematology data. The receiver operating characteristic curve was used to determine the optimal cutoff value of NLR,according to patients who were divided into groups of high NLR(NLR≥3.785)and low NLR(NLR≥3.785).The differences between high and low NLR and clinicopathological features, efficacy of chemotherapy, progression-free survival (PFS), and total survival (OS) were compared. COX regression analysis mode was used to analysis of factors affecting PFS and OS in patients with advanced colorectal cancer. Results The differences in tumor differentiation (P=0.030), ECOG score (P=0.003), CEA (P=0.011), CA19-9 (P=0.047) in the high and low NLR groups were statistically significant. The differences in chemotherapy between the two groups was statistically significant (P<0.001), and the high NLR group was less effective. The median PFS of the high and low NLR groups were 3.44 months and 12.84 months, respectively, and the difference was statistically significant (χ²=39.730, P<0.001). The median OS of the high and low NLR groups was 7.59 months and 22.32 months, respectively, and the difference was statistically significant (χ²=40.505, P<0.001). Cox regression analysis suggested that NLR levels and CEA levels were independent prognostic factors for PFS and OS(P＜0.05). Conclusion High-level NLR is associated with poor chemotherapy response and poor prognosis in patients with advanced colorectal cancer, and was used as an indicator of chemotherapy efficacy and prognosis.

Objective To investigate the characteristics and regularity of CT imaging of colorectal cancer liver metas tases. Methods A retrospective analysis of 84 cases of colorectal cancer liver metastases from March 2016 to March 2018 in our hospital. CT dynamic imaging images and clinical data were recorded and statistically analyzed for different blood flow in flows and different enhancement periods. For the CT imaging results, the patients were divided into the left colon group and the right colon group according to the primary tumor site, and the left colon group was grouped according to the blood vessel reconstruction. Results There was no statistic difference in the distribution of left and right lobe between the primary tumor and the left colon in the left colon （P>0.05） .

The study was to analyze the knowledge of cancer prevention and treatment in healthy people and cancer patients, to contrast the preferred hospital by healthy people and cancer patients, to acquaint the flow direction in seeking medical service, behavior and way to diagnosis cancer of tumor patients. Results In patients with cancer, the understanding proportion of patients with precancerous lesions, early tumor symptoms, and high risk groups was significantly higher than that in healthy people [26.93% (370/1 374), 39.96% (549/1 374), 46.00% (632/1 374) vs 14.49% (162/1 118), 21.91% (245/1 118), 26.92% (301/1 118)].

Discovery and diagnosis of cancer, further consultation, and rehabilitation were mainly carried out in 3A hospital. In patients with cancer, the cancer discovery ratio because of physical discomfort for medical attention was significantly higher than that in unit staff physical examination, self-inspection found, and physical examination in community health service center.
