Abstract Hepatectomy and transplantation are the main surgical therapies for HCC patients, and radiotherapy or chemotherapy is often used as adjuvant treatment. Researches have evaluated the independent predictors of HCC, but evidence for factors predicting the efficacy of chemotherapy is rare. Patients diagnosed with HCC between 2010 and 2015 from the SEER database were included and randomly divided into non-chemotherapy and chemotherapy groups. The predictors of CSS and OS were analyzed with the Cox proportional-hazards regression model and Fine and Gray’s competing risk model. Although ther

Abstract Background Early detection of biliary atresia (BA) is a great challenge providing the main useful way to improve its clinical consequence. Promising metabolomics provides an effective method for determining innovative biomarkers and biochemical ways for improving early diagnosis. This study aimed to determine the benefit of serum and urinary potential bile acid metabolites in the differentiation of BA from non-biliary atresia (non-BA) cases using tandem mass spectrometry (MS/MS). Fourteen bile acids metabolites were measured quantitively by MS/MS in serum and urine samples from 102 ch

Background : Several studies show that cohabiting adult children have less frequent contact with their mothers than married adult children. We argue that these findings might be spurious due to confounding. Objective : Our aim is to replicate earlier research using more robust statistical instruments from the family of multi-level models with fixed effects, which are known to offer better control of omitted-variable bias. We also want to show the extent to which union-type effects vary across countries and by parenthood status. Methods : We use data from the SHARE survey. Mothers are the prima

Signal transducer and activator of transcription 3 (STAT3) is one of the important molecules regulating the chemotherapy sensitivity of cancer cells. The liposome BP1003 targeting the antisense oligonucleotide of STAT3 mRNA can inhibit the expression of STAT3 and increase the chemotherapy sensitivity. However, the effect of BP1003 on the sensitivity of pancreatic cancer cells to albumin-bound paclitaxel remains unclear. The purpose of this study was to investiga
