Objective:To monitor the dynamic changes in coagulation function and assess their clinical significance in patients with gas-tric cancer by using thromboelas to gram (TEG). Methods:A total of 178 patients with gastric cancer from March 2014 to May 2015 in Xinxiang Central Hospital were selected as the experimental group. The patients were grouped based on different tumor stages, inva-sion depths, and lymph node metastasis. The TEG results of all patients were dynamically monitored before and after operation, and 60 healthy persons were selected as normal control group. Blood coagulation change was analyzed by comparing the TEG test results. Results:Compared with those of the control group, the TEG parameters of the experimental group showed significantly decreased R and K values, as well as significantly increased Angle, CI, and MA values, and the differences were statistically significant (P<0.05). In the experimental group, the K values were significantly decreased after operation, whereas Angle, MA, and CI were significantly in-creased (P<0.05). No significant changes were observed in R, LY30, and others. TEG values were significantly different in the compari-son of values for tumor patients with different stages, different tumor infiltration degrees, and with or without lymphatic metastasis. Conclusion:Blood hypercoagulability in the perioperative period was observed in patients with gastric cancer and was positively corre-lated with tumor stages, tumor infiltration degrees, and lymphatic metastasis. Dynamic monitoring of gastric cancer perioperative TEG can provide valuable information for clinical treatment, improve the safety of gastric cancer surgery, and reduce postoperative compli-cations associated with active clinical significance.

Objective To investigate the expression of centromeric protein F(CENPF)and microribonucleic acid 1-3p(miR-1-3p)in the serum of patients with advanced gastric cancer and their correlation with prognosis.Methods Sixty patients with advanced gastric cancer admitted to our hospital from March 2019 to March 2020 were collected as the study group,while 60 healthy volunteers who underwent physical examinations at our hospital's physical examination center during the same period were collected as the control group.Real-time fluorescence quantitative PCR(qRT-PCR)method was applied to detect the expression levels of serum CENPF and miR-1-3p in each group;Pearson method was applied to analyze the correlation between serum levels of CENPF and miR-1-3p;Kaplan-Meier method was applied to analyze the relationship between the expression of CENPF,miR-1-3p,and prognosis in patients with advanced gastric cancer;and COX regression was applied to analyze risk factors affecting the prognosis of patients with advanced gastric cancer.Results Compared with the control group,the CENPF level in the study group was obviously increased,while the miR-1-3p level was obviously reduced(P＜0.05).The correlation analysis results showed that there was a negative correlation between serum CENPF and miR-1-3p levels in patients with advanced gastric cancer(r =-0.650,P＜0.001).There were obvious differences in CENPF and miR-1-3p levels among different TNM stages and lymph node metastasis status(P＜0.05).The 3-year survival rate of patients in the high expression group of CENPF was 19/30(63.33%),which was obviously lower than that in the low expression group,28/30(93.33%)(χ2 = 7.954,P＜0.001);the 3-year survival rate of patients in high expression group of miR-1-3p was 29/30(96.67%),which was obviously higher than that in the low expression group,18/30(60.00%)(χ2 = 11.882,P = 0.001).Multivariate COX regression analysis showed that TNM staging,lymph node metastasis,CENPF,and miR-1-3p expression were risk factors affecting the prognosis of patients with advanced gastric cancer(P＜0.05).Conclusion The serum CENPF level in patients with advanced gastric cancer obviously increase,while miR-1-3p level obviously decrease,both of which are related to prognosis.
