High expression of Fightless I (FLII) is associated to multiple tumors. Based on our previous study that FLII might be involved in the nuclear export, we assessed the possible interaction of FLII with the nuclear envelop associating proteins Importin β and Nup88. We first constructed GST-FLII, GST-LRR recombinant plasmids and transformed them into the Rosetta strain to produce GST-FLII, GST-LRR fusion protein. After purification of these proteins, GST-pull down, as well as co-immunoprecipitation, were used to test the interaction of FLII with Importin β and Nup88. FLII interacted with Importin β and Nup88, and FLII LRR domain is responsible for these interactions. Thus, FLII may play a role in nuclear export through interaction with Importin β and Nup88.

Objective To investigate the clinical application of serum interleukin-6 (IL-6)and interleukin-22 (IL-22) levels in predicting the recurrence of hepatitis B virus (HBV)-related early hepatocellular carcinoma (HCC) after receiving microwave ablation (MWA).Methods Preoperative peripheral blood samples were collected in 49 patients with early-stage HBV-related HCC,and serum concentrations of IL-6 and IL-22 were measured by using ELISA.Thirty healthy volunteers were recruited and used as the control group.The xtile software was used to define the best cut-off value,and the IL-6 and IL-22 levels were divided into highlevel group and low-level group.The tumor-free survivals of high-level and low-level groups were analyzed with Kaplan-Meier analysis,log rank test was adopted to determine the difference,and Cox regression model was employed to screen the risk factors affecting HBV-related HCC recurrence.Results The serum IL-6 and IL-22 levels of HCC group were 13.20 pg/ml (11.87-15.79 pg/ml) and 42.18 pg/ml (34.39-57.44 pg/ml) respectively,which were significantly higher than 10.47 pg/ml (9.50-13.82 pg/ml) and 25.45 pg/ml (22.31-30.12 pg/ml) of the control group (P=0.001 and P＜0.001 respectively).Kaplan-Meier analysis revealed that preoperative lower IL-6,higher total bilirubin and lower albumin levels indicated a shorter disease-free survival (DFS),and IL-22 levels had no statistically significant effect on the recurrence of HCC.Cox regression multivariate analysis showed that lower serum IL-6 level (≤ 13.2 pg/ml;hazard ratio=3.721;95％ CI=1.674-8.272;P=0.001) and lower serum albumin level (≤41.0 g/L;hazard mtio=2.085;95％CI=1.101-3.950;P=0.024) were independent risk factors affecting HBV-related HCC recurrence Conclusion Preoperative serum IL-6 level and serum albumin level can be used as the predictors of HCC recurrence in patients with HBV-related early HCC who are receiving MWA treatment.(J Intervent Radiol,2017,26:232-236)

Objective:To investigate the significance of collagen triple helix repeat containing 1 (CTHRC1) gene expression in colon adenocarcinoma based on bioinformatics.Methods:The GEPIA2 analysis tool was used to analyze the expression of CTHRC1 gene in colon adenocarcinoma and the relationship between its expression and the survival prognosis of patients in The Cancer Genome Atlas (TCGA) database and GTEx database. ULACAN analysis tool was used to analyze the methylation level of CTHRC1 gene in colon adenocarcinoma tissues and normal colon tissues in TCGA database. The cBioportal network analysis tool was used to analyze the mutation of CTHRC1 gene. TIMER analysis tool was used to analyze the relationship between CTHRC1 expression and immune cells infiltration, tumor-associated fibroblasts infiltration and functional immune cells. STRING database was used to analyze the proteins interacted with CTHRC1, and the enrichment analyses were performed.Results:The expressions of CTHRC1 gene and protein in colon adenocarcinoma tumor tissues were higher than those in normal colon tissues, and the differences were statistically significant (both P < 0.05), and CTHRC1 gene showed high methylation level in normal colon tissues and low methylation level in tumor tissues ( P < 0.05). A total of 19 mutations were detected in 2 480 colorectal adenocarcinoma and colon adenocarcinoma samples. Among them, 3 cases of colon adenocarcinoma specimens had CTHRC1 mutations, the mutation sites were R235H, A124V and R193C, and the mutation types were all missense mutations. CTHRC1 gene expression was positively correlated with infiltrations of CD8 + T cells, CD4 + T cells, macrophages, neutrophils, dendritic cells and tumor-associated fibroblasts (all P < 0.01). The overall survival and disease-free survival of patients with high expression of CTHRC1 gene were worse than those of patients with low expression of CTHRC1 gene (all P < 0.05). Conclusions:The methylation of CTHRC1 gene and the infiltration of tumor-associated immune cells may have important significances in the pathogenesis of colon adenocarcinoma. CTHRC1 gene expression and immune cells infiltration can be used as predictors of the survival prognosis of colon adenocarcinoma patients.

Objective To investigate the efficacy and prognostic factors of non-small cell lung cancer (NSCLC) leptomeningeal metastasis (LM) patients undergoing treatment with epidermal growth factor receptor tyrosine kinase inhibitors(EGFR-TKIs).Methods The clinical data of 30 patients with NSCLC- LM were retrospectively analyzed, including the basic situation, survival time, clinical characteristics,pathological type,differentiation degree and treatment method.The median survival time (MOS) was calculated by Kaplan-Meier method. The log-rank test was used to analyze the prognostic single factors.The Cox regression model was used to analyze the multivariate factors. Results The log-rank test result showed that sex,pathological type,differentiation degree and EGFR-TKIs treatment were the influencing factors of MOS(P<0.05).The multivariate analysis result showed that sex,pathological type, differentiation degree and EGFR-TKIs treatment were the independent influencing factors of prognosis in NSCLC-LM patients (P<0.05), and the female gender (RR = 0.090, 95% CI 0.048 -0.140),adenocarcinoma(RR=0.108,95% CI 0.073-0.134),well differentiation(RR=0.112,95% CI 0.076 - 0.141), using EGFR-TKIs treatment (RR = 0.042, 95% CI 0.012 - 0.074) were significant predictors of a good prognosis. Conclusions The female gender, well differentiation, adenocarcinoma and EGFR-TKIs treatments are significant predictors of a good prognosis. EGFR-TKIs can prolong the survival time of patients with NSCLC-LM,and it is recommended for a clinical treatment for patients with NSCLC-LM.
