BACKGROUND Gastroesophageal reflux disease (GERD) is one of the most common gastric pathologies. Recently, there has been a growing interest in the healing effects of mineral waters (MW). METHODS 90 patients with GERD were under observation. The study used the following methods anamnestic, clinical, studies of biochemical blood parameters, ultrasonographic studies of the digestive system, fibroesophagogastroduodenoscopy with intragastric pH-metric. After preliminary research, all patients were randomly divided into three groups of 30 people. The control group who were prescribed a basic treatment complex - dietary and proton pump inhibitor group drugs. Patients of II group in addition to the standard course of treatment received boric highly mineralized bicarbonate sodium water. Patients of III group in addition to the basic therapy were prescribed an internal course treatment of highly mineralized sulfate- bicarbonate sodium-magnesium water. RESULTS The use of the basic complex of treatment for a month in control group did not lead to a significant leveling of signs of dyspeptic and asthenic syndromes. The use of boron highly mineralized sodium bicarbonate water led to a significant leveling of signs of abdominal pain and dyspeptic syndromes, improvement of acid-forming function of the stomach, but no reliable dynamics were observed in eliminating signs of cytolytic, mesenchymal inflammatory and cholestatic syndromes. Application of highly mineralized sulfate-hydrocarbonate sodium magnesium water improves the elimination of dyspepsia and pain syndromes, normalization of the functional state of the liver. CONCLUSIONS The obtained data confirm the prospects of using highly mineralized mineral waters in the complex treatment of GERD patients.BACKGROUND With the growing global burden of gastric carcinoma (GC) and the urgent need for biomolecular targeted therapies, this study aimed to elucidate the relationship between EphA1 and the tumor microenvironment (focusing primarily on the key inflammatory cytokines IL-6 and tumor angiogenic cytokine VEGF) to identify a new potential therapeutic target. MATERIAL AND METHODS IHC and qRT-PCR were performed to quantify the protein and gene expression levels of EphA1, IL-6, and VEGF in normal mucosal tissues, carcinoma tissues, and paracarcinomatous tissues from 57 GC patients. Spearman's rank correlation test was performed to determine the relationship between EphA1, IL-6, and VEGF expression levels. The relationships of EphA1 with clinicopathologic parameter and survival in GC patients were also evaluated. RESULTS The protein and gene expression levels of EphA1 were all attenuated gradually from carcinoma tissues to paracarcinomatous tissues and then to normal mucosal tissues in GC patients. Additionally, significant correlations between the overexpression of EphA1 with aggressive clinicopathological features and shorter survival time of GC patients were verified. In particular, we found a significant positive correlation between the expression of EphA1 and tumor microenvironment hallmark proteins IL-6 and VEGF in carcinoma tissues and paracarcinomatous tissues. CONCLUSIONS EphA1 can promote the occurrence and development of GC by its selective high expression in cancer tissues and its relationship with malignant clinical features and prognosis of GC patients. The underlying potential mechanism appears to involve enhancement of the tumor microenvironment, which via drives the expression of tumor microenvironment hallmark proteins IL-6 and VEGF.BACKGROUND This study was performed to estimate the genetic effects of HtrA1 polymorphisms rs1049331 and rs11200638 on treatment response in stage III colon cancer patients receiving 5-FU-based chemotherapy. MATERIAL AND METHODS A total of 105 stage III colon cancer patients who received postoperative 5-FU based adjuvant chemotherapy were included in our study. Chemotherapy was performed in 3 cycles for the patients. HtrA1 rs1049331 and rs11200638 polymorphisms were genotyped via polymerase chain reaction with sequencing method. The treatment response was estimated according to the RECIST guidelines. RESULTS The response rate of the eligible patients was 53.33%. For rs1049331, the presences of TT genotype and T allele indicted reduced chemotherapy sensitivity (adjusted TT OR=1.736, 95%CI 1.001-3.011, P=0.049; T OR=1.801, 95%CI 1.054-2.932, P=0.039). The rs11200638 polymorphism had no significant association with chemotherapy sensitivity in the study population (P>0.05 for all). CONCLUSIONS HtrA1 rs1049331 polymorphism, but not rs11200638 polymorphism, can influence individual sensitivity to 5-FU-based treatment in stage III colon cancer patients.BACKGROUND Worldwide, hepatocellular carcinoma (HCC) is one of the most commonly diagnosed malignant diseases and is the third leading cause of cancer-related death. This study aimed to investigate the effect of hydroxypyridinone-coumarin (HPC) on MHCC97 and HepG2 human HCC cells and the mechanisms involved. MATERIAL AND METHODS MHCC97 and HepG2 human HCC cells were cultured in vitro. An MTT cytotoxicity assay was used to assess cell viability and proliferation, with and without treatment with HPC. Cell autophagosomes were labeled with GFP-LC3 using confocal fluorescence microscopy. Western blot was used to measure protein expression. RESULTS HPC significantly reduced the cell proliferation rate in a concentration-dependent manner, with 2 µM of HPC resulting in a reduced proliferation rate of MHCC97 cells (by 36%) and HepG2 cells (by 29%) (P less then 0.02). HPC significantly reduced autophagy in MHCC97 and HepG2 cells. Western blot showed that treatment with HPC significant upregulated Atg5, beclin-1, LC3-phosphatidylethanolamine conjugate (LC3-II), and Atg-3, reduced p62 and Akt protein expression, and induced phosphorylation of ERK1/2. GFP-LC3B labeling in MHCC97 and HepG2 cells was increased following HPC treatment. CONCLUSIONS HPC induced autophagy and inhibited the proliferation of MHCC97 and HepG2 HCC cells in vitro and involved activation of ERK1/2 and down-regulation of the Akt pathway.BACKGROUND The treatment of inflammatory bowel disease aims to induce and maintain disease remission, avoid complications, and restore quality of life. The treatments include the use of immunosuppressants and biological therapy. Despite the effectiveness of these treatments in controlling disease activity and in limiting complications, there remains an increased risk of developing malignancies. CASE REPORT A 70-year-old male patient with ulcerative colitis who had pancolitis was initially treated with mesalazine. Adezmapimod mw In 2010, the medication was changed to azathioprine due to clinical disease activity. The patient demonstrated clinical and endoscopic response to the medication, but presented recurrent facial lesions identified as non-melanoma skin cancer in 2014, 2015, and 2016. Azathioprine was discontinued and anti-TNF therapy was started, but no satisfactory clinical or endoscopic response was observed. The patient developed hematuria and a ureter tumor was found with subsequent ureteronephrectomy. Moreover, the patient underwent total colectomy with ileostomy as a treatment for refractory ulcerative colitis.
