Throughout the world, esophageal cancer patients had a greater suicidal risk compared with ordinary people. Thus, we aimed to affirm suicide rates, standardized mortality rates, and underlying suicide-related risk factors of esophageal cancer patients. Patients suffering esophageal cancer were chosen from the Surveillance, Epidemiology, and End Results repository in 1975–2016. Suicide rates as well as standardized mortality rates in the patients were measured. Univariable and multivariable Cox regression had been adopted for establishing the latent suicide risk factors among patients suffering esophageal cancer. On multivariable Cox regression, gender (male vs. female, HR: 6.37), age of diagnosis (70–105 vs. 0–55, HR: 2.69), marital status, race (white race vs. black race, HR: 6.64; American Indian/Alaska Native, Asian/Pacific Islander vs. black race, HR: 8.60), histologic Grade (Grade III vs. Grade I, HR: 2.36), no surgery performed (no/unknown vs. yes, HR: 2.01), no chemotherapy performed were independent risk factors related to suicide in patients suffering esophageal cancer. Male sex, the older age, unmarried state, non-black race, histologic Grade III, no surgery performed, no chemotherapy performed were strongly related to suicide in patients suffering esophageal cancer.

Background Throughout the world, hepatocellular carcinoma (HCC) remains the primary type of liver cancer. The suicide risk was higher among patients with HCC than the general population. Hence, the purpose of this study was to confirm the suicide rates, standardized mortality ratios (SMRs), and the potential risk factors associated with suicide among HCC patients. Methods HCC patients were collected from the Surveillance, Epidemiology, and End Results (SEER) database during 1975–2016. Suicide rates and SMRs among these patients were calculated, and the general population of the United States (U.S.) during 1975–2016 was used as a reference. Univariable and multivariable Cox regression were taken to find out the underlying risk factors of suicide in HCC patients. Results There were 70 suicides identified among 102,567 individuals with HCC observed for 160,500.88 person years. The suicide rate was 43.61 per 100,000 person-years, and SMR was 2.26 (95% CI: 1.78–2.84). On Cox regression, year of diagnosis (1975–1988 vs . 2003–2016, HR: 3.00, 95% CI: 1.01–8.89, P = 0.047; 1989–2002 vs . 2003–2016, HR: 1.92, 95% CI: 1.10–3.34, P = 0.021), gender (male vs. female, HR: 8.72, 95% CI: 2.73–27.81, P < 0.001), age at diagnosis (63–105 years old vs . 0–55 years old, HR: 2.28, 95% CI: 1.21–4.31, P = 0.011), race (white race vs . American Indian/Alaska Native, Asian/Pacific Islander, HR: 3.02, 95% CI: 1.35–6.76, P = 0.007) were independent risk factors of suicide among HCC patients. Conclusions Diagnosed in the early years (1975–2002), male sex, the older age (63–105 years old), white race, survival months (＜2 months) were significantly associated with suicide among HCC patients. For the sake of preventing suicide behaviors, the government, clinicians, and family members should take adequate measures to decrease the rate of suicide, especially in patients with high-risk factors of suicide.

Background: Autoimmune liver disease (ALD) is a chronic liver disease caused by immune dysfunction in the body. However, no causative or curative medical treatment with proven efficacy exists to cure ALDs, and liver transplantation (LT) remains the only effective treatment available. However, the problem of recurrence of ALDs (rALDs) still remains after LT, which seriously affects the survival rate of the patients. Therefore, clinicians need to be aware of the risk factors affecting rALDs after LT. Therefore, this meta-analysis aims to define the risk factors for rALDs, which include the recurrence of primary biliary cirrhosis, primary sclerosing cholangitis and autoimmune hepatitis. Methods: A systematic search in Pubmed, Embase, Cochrane library and Web of Science databases was performed from 1980 to 2019. The inclusion criteria were risk factors for developing rALDs after LT. However, case series, case reports, reviews, meta-analysis and studies only including human immunodeficiency virus cases, children, and pregnant patients were excluded. Results: The electronic database search yielded 1728 results. Sixty-three retrospective cohort studies met the inclusion criteria and 13 were included in the meta-analysis. The final cohort included 5077 patients, and among them, 21.96% developed rALDs. Colectomy before LT, HR 0.59 (95% confidence interval [CI]: 0.37-0.96), cholangiocarcinoma, HR 3.42 (95% CI: 1.88–6.21), multiple episodes of acute cellular rejection, HR 2.07 (95% CI: 1.27–3.37), model for end-stage liver disease score, HR 1.05 (95% CI: 1.02–1.08), use of mycophenolate mofetil, HR 1.46 (95% CI: 1.00–2.12) and the use of cyclosporin A, HR 0.69 (95% CI: 0.49–0.97) were associated with the risk of rprimary sclerosing cholangitis. In addition, the use of tacrolimus, HR 1.73 (95% CI: 1.00–2.99) and cyclosporin A, HR 0.59 (95% CI: 0.39–0.88) were associated with the risk of rALD. Conclusions: Multiple risk factors for rALDs were identified, such as colectomy before LT, cholangiocacinoma, multiple episodes of acute cellular rejection, model for end-stage liver disease score, and especially the use of mycophenolate mofetil, cyclosporin A and tacrolimus.

Our study suggests that EZH2 and Bmi-1 are up-regulated while miR-203 is down-regulated in Hep3B cells. MiR-203 may contribute to the metastasis and enhance apoptosis of HCC cells by regulating EZH2 and Bmi-1. Our study may provide a theoretical basis for metastasis of HCC and targeted therapy of HCC.

Background/Aims: Increasing evidence has indicated that Forkhead box protein C2 (FOXC2) plays an important role in carcinogenesis. However, the expression and the role of FOXC2 in hepatocellular carcinoma (HCC) have not been extensively studied. Methods: FOXC2 expression was analyzed by quantitative real-time polymerase chain reaction, Western blot analysis and immunohistochemistry in HCC tissue and cells. The relationship between FOXC2 expression and patient clinical significance and survival were assessed by Pearson’s correlation and Kaplan-Meier analysis, respectively. Cell proliferation assays, colony formation assays, flow cytometric analysis and Transwell assays were employed to measure the effects of FOXC2 on HCC cells in vitro. Results: The expression of FOXC2 was increased in HCC tissue, and high FOXC2 expression was associated with worse patient survival. Knockdown of FOXC2 inhibited HCC cell growth, migration, and invasion in vitro, as well as tumor growth. Furthermore, we found that activation of AKT-mediated MMP-2 and MMP-9 was involved in FOXC2 promoting an aggressive phenotype. Conclusions: Taken together, these findings demonstrate that FOXC2 is upregulated in HCC tissue and is associated with tumor size, vascular invasion and advanced TNM stage. Further investigation suggested that FOXC2 may play a vital role in promoting proliferation and invasion in HCC and serves as a novel therapeutic target in HCC.

Background:Contribution of model for end-stage liver disease incorporating with serum sodium (MELD-Na) score in predicting acute kidney injury (AKI) after orthotopic liver transplantation (OLT) is yet to be identified. This study assessed the prognostic value of MELD-Na score for the development of AKI following OLT.Methods:Preoperative and surgery-related variables of 321 adult end-stage liver disease patients who underwent OLT in Fuzhou General Hospital were collected. Postoperative AKI was defined and staged in accordance with the clinical practice guidelines developed by Kidney Disease: Improving Global Outcomes. Univariate and multivariate analysis was performed to determine the risk factors for AKI following OLT. The discriminating power of MELD/MELD-Na score on AKI outcome was evaluated by receiver operating characteristic (ROC) curve. Spearman's correlation analysis was used for identifying the correlated relationship between MELD/MELD-Na score and the severity levels of AKI.Results:The prevalence of AKI following OLT was in 206 out of 321 patients (64.2%). Three risk factors for AKI post-OLT were presented, preoperative calculated MELD score (odds ratio [OR] = 1.048, P = 0.021), intraoperative volume of red cell suspension transfusion (OR = 1.001, P = 0.002), and preoperative liver cirrhosis (OR = 2.015, P = 0.012). Two areas under ROC curve (AUCs) of MELD/MELD-Na score predicting AKI were 0.688 and 0.672, respectively; the difference between two AUCs was not significant (Z = 1.952, P = 0.051). The Spearman's correlation coefficients between MELD/MELD-Na score and the severity levels of AKI were 0.406 and 0.385 (P = 0.001, 0.001), respectively.Conclusions:We demonstrated that preoperative MELD score, intraoperative volume of red cell suspension transfusion and preoperative liver cirrhosis were risk factors for AKI following OLT. Furthermore, we preliminarily validated that MELD score seemed to have a stronger power discriminating AKI post-OLT than that of novel MELD-Na score.

Growing evidence has shown that coffee consumption is inversely related with the risk of hepatocellular carcinoma. It is suggested that caffeine maintains strong antioxidative activity. With this property, coffee intake may lead to the inhibition of cell proliferation of liver cancer cells; also, some compounds contained in coffee can reduce the genotoxicity of aflatoxin B1 in vitro and lower the damage caused by some carcinogens. A computerized search was performed in PubMed to identify relevant articles published before August 2015. Eleven relevant studies were included with a total of 2,795 cases and 340,749 control subjects. According to the meta-analysis we performed, the pooled odds ratio (OR) from all included studies was 0.49 (95% confidence interval [CI] =0.46–0.52). The subgroup analysis indicated that the pooled ORs for Asian studies and other populations were 0.27 (95% CI =0.23–0.31) and 0.82 (95% CI =0.77–0.87), respectively. The overall pooled OR for high consumption was decreased to 0.21 (95% CI =0.18–0.25) and significance was observed. Among other populations, the pooled OR of subjects with high coffee consumption was 0.65 (95% CI =0.56–0.73) compared to the nondrinker. The corresponding OR of five Asian studies was 0.13 (95% CI =0.09–0.17). The findings from this meta-analysis further confirmed the inverse association between the coffee consumption and hepatocellular carcinoma risk with quantitative evidence. The protective effect can be detected among healthy population and patients with chronic liver diseases, and the consumption can also prevent the development of liver cirrhosis.
