Efficacy and safety of vedolizumab in the treatment of patients with inflammatory bowel disease: A systematic review and meta‑analysis of randomized controlled trials.

Few studies have thoroughly assessed the efficacy and safety of vedolizumab (VDZ) in the treatment of inflammatory bowel disease (IBD). Therefore, this systematic review and meta-analysis was performed to further evaluate this association. PubMed, Embase, and the Cochrane databases were searched until April 2022.

CUL4B increases platinum-based drug resistance in colorectal cancer through EMT: A study in its mechanism.

Platinum-based chemotherapy drugs play a very important role in the treatment of patients with advanced colorectal cancer, but the drug resistance of platinum-based chemotherapy drugs is an important topic that puzzles us. If we can find mechanisms of resistance, it will be revolutionary for us. We analysed the differential genes, core genes and their enrichment pathways in platinum-resistant and non-resistant patients through a public database.

Vitamin D intake as well as circulating 25-hydroxyvitamin D level and risk for the incidence and recurrence of colorectal cancer precursors: A meta-analysis.

Objective: Vitamin D consumption and circulating 25(OH)D level are associated with decreased risk of colorectal cancer (CRC) and colorectal adenoma (CRA), but few studies have assessed their relationship with the incidence and recurrence of CRC precursors. Therefore, we performed this meta-analysis to further evaluate the association.

Methods: We searched PubMed, Web of Science, Scopus and Embase databases in English until August 2021.

MicroRNA-23a promotes colorectal cancer cell survival by targeting PDK4.

MicroRNA (miR) is important regulators of gene expression, and aberrant miR expression has been linked to oncogenesis; however, little is understood about their contribution to colorectal cancer (CRC). Here, we determined that miR-23a is overexpressed in human colorectal cancer cell lines and tissues compared with that of normal cells. The stable over-expression of miR-23a in CRC cells was sufficient to promote cell proliferation in vitro and in vivo.

Lentivirus-mediated RNAi knockdown of insulin-like growth factor-1 receptor inhibits the growth and invasion of hepatocellular carcinoma via down-regulating midkine expression.

The insulin-like growth factor-1 receptor (IGF-1R) overexpression contributes to the development of a variety of cancers. The present study explored the role of IGF-1R in the development and progression of hepatocellular carcinoma (HCC) and the possibility of IGF-1R silencing by lentivirus-mediated RNA interference (RNAi) as a therapeutic target for HCC. We showed that IGF-1R mRNA was up-regulated in Huh7 and Hep3B cells and human HCC tissues, and that IGF-1R knockdown by RNAi led to decreased proliferation, apoptosis induction, and decreased migration and invasion of Huh7 and Hep3B cells.

Daclatasvir combined with peginterferon-α and ribavirin for the treatment of chronic hepatitis C: a meta-analysis.

Daclatasvir, a HCV NS5A inhibitor, is a new direct-acting antiviral drug for chronic hepatitis C (CHC). This study aimed to evaluate the efficacy and safety of daclatasvir combined with peginterferon-α (pegIFN-α) and ribavirin (RBV) for the treatment of CHC. The databases of PUBMED, EMBASE, COCHRANE, WANFANG, and CNKI were retrieved to identify eligible studies.

Induction of autophagy and apoptosis by miR-148a through the sonic hedgehog signaling pathway in hepatic stellate cells.

Autophagy is an evolutionarily conserved biological process that is activated in response to stress. Increasing evidence indicate that dysregulated miRNAs significantly contribute to autophagy and are thus implicated in various pathological conditions, including hepatic fibrosis. MiR-148a, a member of the miR-148/152 family, has been found to be downregulated in hepatic fibrosis and human hepatocellular carcinoma.

Hes1 promotes cell proliferation and migration by activating Bmi-1 and PTEN/Akt/GSK3β pathway in human colon cancer.

Hes1 is a transcription factor that influences cell proliferation and differentiation. However, the effect of Hes1 on invasiveness and the underlying mechanism remain unknown. In the current study, we found that Hes1 suppressed cell apoptosis, promoted cell growth, induced EMT phenotype and cytoskeleton reconstruction, and enhanced the metastatic potential of colon cancer cells in vitro and in vivo.

Epigenetic modulation of insulin-like growth factor-II overexpression by hepatitis B virus X protein in hepatocellular carcinoma.

Hepatitis B virus X protein (HBx) is involved in the pathogenesis of hepatocellular carcinoma (HCC). Overexpression of the transcripts from the P3 and P4 promoters of the insulin-like growth factor-II (IGF-II) gene is observed in HCC. The present study investigated the involvement of HBx in IGF-II overexpression and its epigenetic regulation.

Decaprenyl diphosphate synthase subunit 2 as a prognosis factor in hepatocellular carcinoma.

Aim: To investigate the involvement of decaprenyl diphosphate synthase subunit 2 (PDSS2) in development and progression of human hepatocellular carcinoma (HCC).

Methods: PDSS2 protein expression was examined in well- and poorly differentiated HCC tumor samples. The levels of PDSS2 expression were compared with clinical features and prognosis of HCC patients.

Ultrasound-guided endoscopic biliary drainage: a useful drainage method for biliary decompression in patients with biliary obstructions.

Background: Endoscopic retrograde cholangiopancreatography with fluoroscopy guidance is a well-established technique for providing biliary drainage in patients with biliary obstructions. However, fluoroscopic facilities may not always be available and fluoroscopy carries a risk of radiation exposure.

Aim: We retrospectively compared the procedure success rate and efficacy of ultrasound-guided endoscopic biliary drainage (UG-EBD) and fluoroscopy-guided endoscopic biliary drainage (FG-EBD) in patients with biliary obstructions.

β-Nerve growth factor attenuates hepatocyte injury induced by D-galactosamine in vitro via TrkA NGFR.

Nerve growth factor (NGF) regulates the proliferation, differentiation and survival of cells and is also involved in the wound healing and tissue remodeling processes. The biological effects of NGF are dependent upon receptor signal-mediating functions, which differ between cells. This study attempted to investigate the hepatoprotective effect and possible mechanism of β-NGF on D-galactosamine (D-GalN)-injured human liver L-02 cell lines.

The value of model for end-stage liver disease and Child-Turcotte-Pugh scores over time in evaluating the prognosis of patients with decompensated cirrhosis: experience in the Chinese mainland.

Aim: In addition to the model for end-stage liver disease (MELD) and Child-Turcotte-Pugh (CTP) score, the change in MELD score (DeltaMELD) and CTP (DeltaCTP) over time, as well as the modified CTP score, have been proposed as predictive factors for patients with advanced liver cirrhosis. We investigated the ability of the above scoring systems to predict the outcome of decompensated cirrhosis in the Chinese mainland.

Methods: A cohort of 160 patients with advanced liver cirrhosis who were followed up were studied prospectively.

Hypomethylated P4 promoter induces expression of the insulin-like growth factor-II gene in hepatocellular carcinoma in a Chinese population.

Purpose: The expression of human insulin-like growth factor-II (IGF-II) is regulated by the activation of four promoters (P1-P4) acting in a development-dependent, tissue-specific manner. IGF-II overexpression associated with P3 and P4 activation is observed in animal and human hepatocarcinogenesis. We correlated P4 epigenetic alteration with P4 transcript activation and clinicopathologic features.

Differential promoter usage for insulin-like growth factor-II gene in Chinese hepatocellular carcinoma with hepatitis B virus infection.

Background: Human insulin-like growth factor-II (IGF-II) gene contains nine exons and four different promoters (P1-P4). Expression of the gene is elevated in the preneoplastic hepatic foci and hepatocellular carcinoma (HCC) of experimental animals and humans. To gain insight into transcriptional regulation of the gene in HCC, we analyzed the relative usage of the P1-P4 promoters and its correlation with the clinical and pathological characteristics in Chinese hepatocellular carcinoma with hepatitis B virus (HBV) infection.
