RÉSUMÉ
Objective To explore the regulatory relationship between CCAAT enhancer binding protein beta(CEBPB)and four-jointed box kinase 1(FJX1)in colon cancer and their effect on colon cancer(CC)malignant progression and angiogenesis.Methods Bioinformatics was used to analyze the expression of FJX1 and CEBPB in CC and the regulatory relationship between them.Real-time quantitative reverse transcription polymerase chain reaction(qRT-PCR)was used to verify the expression of FJX1 and CEBPB in CC cells,and chromatin immunoprecipitation(CHIP)and dual luciferase assay were used to verify the binding relationship between FJX1 and CEBPB.The effects of FJX1 and CEBPB on the viability,migration,invasion and angiogenesis of CC cells were detected by cell counting kit-8(CCK-8),scratch test,Transwell and angiogenesis test.Results This study revealed that FJX1 was highly expressed in CC.Inhibiting the expression of FJX1 could significantly inhibit the cell viability,migration,invasion and angiogenesis of CC cells.Subsequently,we found that CEBPB was an upstream regulatory gene of FJX1,and CEBPB was highly expressed in CC.CHIP and dual luciferase experiments showed that CEBPB could bind to FJX1.The results of cell experiments showed that the transcription factor CEBPB could promote the proliferation,migration,invasion and angiogenesis of CC cells by activating FJX1.Conclusion CEBPB/FJX1 axis played a cancer-promoting role in the progression of CC,suggesting that CEBPB and FJX1 may be potential therapeutic targets for CC.
RÉSUMÉ
Objective To explore the curative effect of colonoscopy combined with laparoscope in the treatment of colonic polyps.Methods The clinical data of 48 cases with colonic polyps were retrospectively analyzed.According to the operation pattern,the patients were divided into observation group(23 cases)and control group(25 cases).The observation group received colonoscopy combined with laparoscopy for radical surgery of colon polyps,the control group used the traditional open surgery to remove polyps.The operation time,bleeding volume, exhaust and defecation time,hospital days and cost as well as postoperative complications were observed.Results The two groups were successfully completed surgery.The operative time,bleeding volume of the observation group were (78.3 ±8.2)min and (1 3.1 ±4.5)mL respectively,which of the control group were (1 1 5.5 ±1 0.1 )min, (63.6 ±1 8.1 )mL,the differences between the two groups were statistically significant(t =1 3.93,1 3.01 ,all P 0.05).Conclusion For simple colonoscopy treatment difficulties of colon polyps,colonoscopy,laparoscopy combined treatment is minimally invasive and can improve the safety,strictly control surgical indications,can give full play to the double mirror combined advantage.
