Objective To investigate the expression of EIF5A1 in intrahepatic cholangiocarcinoma cell lines and human hepatobiliary duct epithelia,and its effect on the proliferation,migration and invasion ability and Wnt/β-Catenin signaling pathway in HUCCT1 cells.Methods Western blot was used to detect the basal expression level of EIF5A1 in intrahepatic cholangiocarcinoma cell lines and human intrahepatic cholangiocarcinoma epithelial cells.Transient transfection of siRNA was used to silence the expression of EIF5A1 in intrahepatic cholangiocarcinoma cell HUCCT1.The experimental groups were divided into blank control group(Con),siRNA1 group,and siRNA2 group.The most effective siRNA was screened by Western blot.The effects of EIF5A1 silencing on the proliferation,migration and invasion ability of HUCCT1 cells were detected by CCK-8,EdU cell proliferation assay and Transwell assay.The effect of EIF5A1 silencing on the Wnt/β-Catenin signaling pathway in HUCCT1 cells was detected by Western blot.Results The results of CCK-8 and EdU cell proliferation experiments showed that the proliferation ability of HUCCT1 cells decreased after EIF5A1 silencing(P<0.05),and Transwell migration and invasion experiments showed that the migration and invasion ability of Hucct1 cells decreased after EIF5A1 silencing(P<0.05).Western blot analysis revealed decreased expression of β-Catenin,Cyclin D1,MMP-2 and Survivin in Wnt/β-Catenin signaling pathway after EIF5A1 silencing(P<0.05).Conclusion EIF5A1 may promote the proliferation,migration and invasion of intrahepatic bile duct cancer cells through Wnt/β-Catenin signaling pathway.

Hepatocellular carcinoma(HCC)is one of the leading causes of cancer-related mortality worldwide.As a typical immunogenic tumor,HCC has a complex immune microenvironment that plays a crucial role in its initiation and progression.In recent years,the interactive network between immunosuppressive cells and circulating tumor cells(CTCs)has drawn increasing attention for its role in promoting HCC immune evasion and metastasis.However,how CTCs escape immune surveillance and clearance by immune cells remains unclear.This article focuses on the regulatory networks between CTCs and immunosuppressive cells as well as the key pathways of immune evasion,introduces exosome-mediated regulation and single-cell multi-omics technologies to dissect mechanisms of cellular interactions,systematically discusses the clinical translational challenges of targeting pathways such as PD-L1 and CCL5,and proposes future prospects for personalized therapy driven by artificial intelligence.

Objective To investigate the feasibility and clinical effects of laparoscopic operation for liver rupture . Methods A retrospective analysis was made on 62 cases of traumatic rupture of liver in this hospital from June 2012 to April 2014.The techniques of hemostasis included coagulation , hemostasis gauze packing , rupture suture , hepatic artery ligation , and debridement hepatectomy. Results The laparoscopic operation was successfully completed in 56 cases, with a success rate of 90.3%(56/62). Conversion to open surgery was required in 6 cases due to massive hemorrhage and difficult location of lesions , including 2 cases of grade Ⅲliver rupture , 3 cases of grade Ⅳ, and 1 case of grade Ⅴ.Patients with liver rupture of grade Ⅰ and Ⅱwere all operated without conversions to laparotomy .One patient with grade Ⅲwas complicated with biliary leakage .In patients with grade Ⅳ, one was complicated by biliary leakage and another by obstructive jaundice .In patients with grade Ⅴ, one was complicated by systemic multiple organ dysfunction leading to death and another by biliary tract bleeding who was cured by active symptomatic treatment .The complication rate was 8.1%(5/62).The mortality rate was 1.6%(1/62).All the patients were followed up for three months .All the patients recovered well . Conclusion For grade Ⅰ,Ⅱ, andⅢliver rupture , laparoscopic surgery is safe and feasible .But for grade Ⅳand Ⅴpatients, laparoscopic surgery bears high rates of converting to open operation and postoperative complications , so we suggest open surgery as the first choice .
