BACKGROUND AND STUDY AIMS: The high mobility group A2 (HMGA2), a nonhistone nuclear binding protein, modulates transcription by altering the chromatin architecture of the target gene DNA in its specific AT-hooks region. HMGA2 overexpression has been observed in embryonic tissue and many malignant neoplasms. This study sought to verify whether HMGA2 plays a role in the biological functions of gastric cancer cells, such as cell proliferation, invasiveness, migration, and stem cell acquisition, and to provide some ideas for further research on the metastatic mechanism of gastric cancer. PATIENTS AND METHODS: HMGA2's effects on the proliferation, invasiveness, and migration capabilities of gastric cancer cells were individually detected by BrdU, Transwell, and wound healing assays. Western blotting and immunofluorescence were used to evaluate whether HMGA2 could promote the acquisition of gastric cancer cells. Biostatistical analyses were performed using SPSS 17.0 for Windows. RESULTS: HMGA2 expression levels in gastric cancer cell lines were significantly higher than those in human immortalized gastric epithelial cell lines (p < 0.01). Gastric cancer cell proliferation was inhibited when HMGA2 was overexpressed (p < 0.05). The invasiveness and migration capabilities of gastric cancer cells with HMGA2 overexpression were enhanced more than those of the corresponding control groups (p < 0.05). HMGA2 overexpression promotes the stemness acquisition of stem cells from gastric cancer cells. CONCLUSIONS: This study verified that the HMGA2 structural transcription factor promotes invasiveness, migration, and acquisition of gastric cancer cells. Furthermore, our findings provide significant insight for further research on the metastatic mechanism of gastric cancer.

BACKGROUND AND STUDY AIMS: Esophageal restenosis is a serious complication after esophageal stent placement, which influences the clinical prognosis of stent implantation and the patient's quality of life. TGF-β1/Smads signaling pathway plays an important role in the development of the eosinophilic esophagitis and scar repair after skin trauma. However, the role of TGF-β1/Smads in the development of esophageal restenosis after esophageal stent placement remains unknown. Our study aimed to investigate whether TGF-β1/Smads plays an important role in the development of esophageal restenosis after esophageal stent, and whether the exogenous TGF-β1 inhibitor supplement could ameliorate the esophageal restenosis after esophageal stent. MATERIAL AND METHODS: We established the model of esophageal restenosis after esophageal stenting in rats, and determined the expression levels of TGF-β1/Smads signaling pathway and the relevant markers of fibroblast activation by immunochemistry (IHC), Western Blot and real time qPCR. Those all the indicators were also determined in esophageal fibroblast when exposed to rhTGF-β1 with or without TGF-β1 inhibitor P144. RESULTS: The serum level of IL-1β and TNFα were significantly increased in stent implantation group compared to blank control group, and obviously ameliorated when treated with P144. The TGF-β1/Smads signaling pathway and the relevant markers of fibroblast activation were significantly increased in stent implantation group compared to blank control group, and obviously ameliorated when treated with P144. Those all the indicators were significantly increased when exposed to rhTGF-β1, and obviously decreased when treated with P144. CONCLUSIONS: TGF-β1 Inhibitor P144 could protect against benign restenosis after esophageal stenting by down-regulating the expression levels of relevant markers of fibroblast activation through TGF-β1/Smads signaling pathway inhibition, and may be used as a novel therapy for benign restenosis after esophageal stenting.

Brunner's gland hamartoma (BGH) is a rare, benign tumor of the duodenum. It is mostly asymptomatic and usually found incidentally on routine esophagogastroduodenoscopy (EGD). However, some BGHs present with major complications including anemia, bleeding, obstruction, or dysplasia, requiring management and resection of these lesions. Herein, we present two cases of large BGHs of the duodenum, one presenting as severe gastrointestinal bleeding and the other, noted on EGD for iron deficiency anemia, found to have high grade dysplasia. This literature review discusses the rare serious complications of BGH, including iron deficiency anemia, overt gastrointestinal bleeding, and malignant potential.

BACKGROUND AND STUDY AIMS: The sensitivity of the Liver Imaging Reporting and Data System (LI-RADS) in the diagnosis of hepatocellular carcinoma (HCC) on gadoxetic acid-enhanced magnetic resonance imaging (EOB-MRI) was suboptimal. This study evaluated the LI-RADS diagnostic performance in HCC when modifying the definition of washout using the transition phase (TP) or hepatobiliary phase (HBP) hypointensity on EOB-MRI. PATIENTS AND METHODS: This retrospective study included patients at high risk of HCC who underwent EOB-MRI from June 2016 to June 2021. Three modified LI-RADS (mLI-RADS) algorithms were formulated according to different definitions of washout as follows: (a) portal venous phase (PVP) or TP hypointensity, (b) PVP or HBP hypointensity, and (c) PVP or TP or HBP hypointensity. Diagnostic performance, including sensitivity, specificity, and accuracy, was compared between mLI-RADS and LI-RADS v2018 using McNemar's test. RESULTS: A total of 379 patients with 426 pathologically confirmed hepatic observations (250 HCCs, 88 nonHCC malignancies, and 88 benign lesions) were included in our study. The sensitivity rates of mLI-RADS a-c (80.0 %, 80.8 %, and 80.8 %) were all higher than that of LI-RADS v2018 (74.4 %) (all p < 0.05). The specificity rates of mLI-RADS a-c (86.9 %, 85.8 %, and 85.8 %) were all slightly lower than that of LI-RADS v2018 (88.6 %), although no statistically significant difference was noted (all p > 0.05). The accuracies of the three mLI-RADS algorithms were the same and were all higher than that of LI-RADS v2018 (82.9 % vs. 80.3 %, all p < 0.05). CONCLUSION: When the definition of washout appearance was extended to TP or HBP hypointensity on EOB-MRI, the diagnostic sensitivity of LI-RADS for HCC improved without decreasing specificity.

Non-alcoholic fatty liver disease (NAFLD) is characterized by accumulation of fat in the liver cells caused by means other than alcohol consumption. It is one of the most common chronic liver diseases worldwide and can lead to severe conditions, such as cirrhosis and liver cancer. NAFLD is often associated with other metabolic disorders, such as obesity and diabetes, and is closely related to lifestyle factors, such as diet and physical activity [1]. The diagnosis as well as management of NAFLD are complex and involve a multidisciplinary approach. The available treatment options include lifestyle modifications, pharmacological interventions, and in severe cases, liver transplantation. The increasing prevalence of NAFLD highlights the urgent requirement of effective prevention and management strategies. This disease is a growing health concern in India, given the rise in the incidence of obesity and diabetes. According to a study published in the Journal of Clinical and Experimental Hepatology in 2020, the prevalence of NAFLD in India is estimated to be between 9% and 32%. In accordance with the research population and diagnostic criteria employed, a study published in the Indian Journal of Gastroenterology in 2019 found that the prevalence of NAFLD in India ranged from 9.6% to 32.3% [2]. The same study also revealed that the prevalence of non-alcoholic steatohepatitis (NASH), a highly severe form of NAFLD, ranged from 1.5% to 8.4%. These statistics highlight the need for increased awareness and preventive measures to manage the growing burden of NAFLD in India.

Hydatidosis is an endemic disease in certain areas in the world particularly in the Mediterranean, the Middle East, and South America, caused by a cestode known as Echinococcus granulosus. Humans are the accidental intermediate hosts. The liver and the lungs are the most commonly involved organ. If the parasite passes through the pulmonary capillary bed, the hydatid cyst may develop at any site in the body like bone, pancreas, brain, kidney, and orbit. Isolated spleen hydatid cyst is very rare. We hereby report one observation of isolated hydatid cyst of the spleen in a patient living in non-endemic area and without any potential risk.

Use of Foley catheter in patients with ileostomy, for the decompression of large bowel distal to stoma or for the administration of large bowel enema through colostomy, either to treat constipation or for bowel preparation prior to colonoscopy, is a common practice. Accidental migration of catheter during bowel irrigation through stoma can take place if it is not secured externally to the skin. We present 2 such cases with intra-colonic migration of Foley catheter that occurred during bowel irrigation and were retrieved endoscopically. To our knowledge, this is the first case report of endoscopic removal of Foley catheter that migrated internally through the stoma.

Endoscopy is an important method for diagnosing gastrointestinal (GI) diseases. In this study, we provide an overview of the advances in artificial intelligence (AI) technology in the field of GI endoscopy over recent years, including esophagus, stomach, large intestine, and capsule endoscopy (small intestine). AI-assisted endoscopy shows high accuracy, sensitivity, and specificity in the detection and diagnosis of GI diseases at all levels. Hence, AI will make a breakthrough in the field of GI endoscopy in the near future. However, AI technology currently has some limitations and is still in the preclinical stages.

Illnesses that afflict a tiny number of individuals are referred to as rare diseases (RDs), sometimes called orphan diseases. The local healthcare systems are constantly under financial, psychological, and medical strain due to low incidence rates, unusual presentations, flawed diagnostic standards, and a lack of treatment alternatives for these RDs. The effective management of the once widely spread viral hepatitis B and C has altered the spectrum of liver diseases in Egypt during the last several years. The detection of uncommon disorders such as autoimmune, cholestatic, and hereditary liver diseases has also been made easier by the increasing knowledge and greater accessibility of specific laboratory testing. Finally, despite Egypt's large population, there are more uncommon liver disorders than previously thought. This review article discusses the clinical and epidemiological characteristics of a few uncommon liver disorders and the information currently accessible concerning these illnesses in Egypt.

BACKGROUND AND STUDY AIMS: MicroRNA (miRNA) is involved in diverse biological and physiological processes of tumors. Dysregulation of miRNA will induce a series of human diseases. miR-129-2-3p has vital effects in the pathogenesis of various tumors. However, the regulatory function of miR-129-2-3p in colon cancer remains to be clarified. This study investigated the role of miR-129-2-3p targeting BZW1 in proliferation, apoptosis, migration, and invasion of colon cancer. PATIENTS AND METHODS: Here, RT-qPCR was applied to measure the miR-129-2-3p levels in colon cancer tissues. The predicted targets of miR-129-2-3p were identified by bioinformatics and verified using luciferase reporter assay. The effects of miR-129-2-3p on colon cancer were detected by CCK-8, colony formation, transwell chamber test, wound healing, and flow cytometry assays. Finally, the influence of miR-129-2-3p on tumor growth was studied. Nude mice were xenografted with transfected Lovo cells by subcutaneous injection of 5 × 10 cells in 100 µl. HE staining and TUNEL were used to assess metastasis ability. RESULTS: miR-129-2-3p level in colon cancer tissue was significantly reduced. Furthermore, it was verified that BZW1 was a target of miR-129-2-3p, and its expression in colon cancer cells was inhibited by miR-129-2-3p. Additionally, miR-129-2-3p inhibited colon cancer cell proliferation, colony formation, mobility ability and tumor growth, and promoted cell apoptosis by targeting BZW1. miR-129-2-3p overexpression in tumor xenografts in vivo decreased BZW1 expression, and suppressed tumor growth. CONCLUSION: Collectively, these findings indicated that miR-129-2-3p exerts a suppressive role in colon cancer cells by directly targeting BZW1, and may have significant therapeutic implications for patients with colon cancer.

BACKGROUND AND STUDY AIMS: It has been suggested that the combined detection of multiple serum biomarkers can effectively screen out the high-risk population of chronic atrophic gastritis in the general population. Therefore, it is necessary to establish an effective predictive model of chronic atrophic gastritis. PATIENTS AND METHODS: Serum biopsies were assessed using five stomach-specific circulating biomarkers pepsinogen I (PGI), PGII, PGI/II ratio, anti- H. pylori antibody, and gastrin-17 (G-17) to identify high-risk individuals and evaluate the risk of developing chronic atrophic gastritis. RESULTS: In the cross-sectional analysis, PGII, the PG ratio, G17, anti- H. pylori IgG were positively associated with the presence of chronic atrophic gastritis, and combined prediction of the five biomarkers was more accurate than single-factor prediction ((0.692 vs 0.54(PG1), 0.604 (PGⅡ), 0.616(PGI/II ratio), 0.629(G-17)). CONCLUSION: The combination of PGI, PGII, the PGI/II ratio, G17, and anti-H. pylori antibodies for serological analysis are helpful to screen chronic atrophic gastritis high-risk subjects from the general population and recommend that these people carry out further endoscopy and biopsy.

BACKGROUND AND STUDY AIM: Hepatocellular carcinoma (HCC) is the fifth leading cause of cancer-related mortality worldwide, and, more than half of these cases are diagnosed in China. However, effective treatment for HCC is still limited. MATERIAL AND METHODS: C-X-C motif chemokine receptor 4 (CXCR4) was first activated and inhibited in HepG2 cells using a pharmacological method. HepG2 cell proliferation was detected using the CCK-8 method. Metastasis and apoptosis of HepG2 cells were detected using wound healing and flow cytometry. The expression of each target molecule related to metastasis and invasion, such as MMPs, E-cadherin and the PI3K/AKT/Mcl-1/PARP signaling pathway was detected by western blotting. The secretion of molecular metastases was detected using competitive ELISA. RESULTS: This study constructed a CXCR4 activation and inhibition model in HepG2 cells. CXCR4 inhibition promoted the inhibitory effect of plantamajoside on the proliferation and metastasis of cells, which led to apoptosis. Furthermore, we found that the expression of apoptosis-related proteins was increased after treatment with plantamajoside combined with CXCR4 inhibition. In addition, the expression and secretion of pro-metastatic proteins, including MMPs and E-cadherin were decreased. We also noticed that this effect might be mediated by the PI3K/AKT/Mcl-1/PARP signaling pathway. CONCLUSION: CXCR4 inhibition may contribute to the treatment of HCC. Inhibition of CXCR4 expression contributes to the therapeutic effect of plantamajoside; the effect of plantamajoside might be mediated by the PI3K/AKT/Mcl-1/PARP signaling pathway; and CXCR4 might be a therapeutic target of HCC.

BACKGROUND AND STUDY AIMS: Glypican 2 (GPC2) is a member of the glypican gene family and is expressed in multiple kinds of cancer. However, the function and mechanism of GPC2 in colorectal cancer remains unclear. In this study, we aimed to identify the role of GPC2 on tumor cell proliferation and survival in colorectal cancer. PATIENTS AND METHODS: Ten pairs of colon cancer and matched normal colon tissues were collected in this research. GEPIA was used to analysis the GPC2 gene expression profile in TGCA data base. RT-qPCR and western blot assay were performed to determine the mRNA and protein expressions. CCK-8, Flow cytometry and colon formation assay were applied to evaluate cell viability. IHC staining was performed to evaluate the protein expression in tissues. The function of GPC2 in vivo was verified by an animal model of colon cancer. RESULTS: Through the bioinformatics analysis and qRT-PCR validation, we found that GPC2 was upregulated in the colon cancer tissues and cells. GPC2 knockdown suppressed cell proliferation in vitro and in vivo was confirmed by the results of CCK-8, colony formation assays, and tumor xenograft models. Moreover, by the analysis of flow cytometry assay and gain-or-loss function experiments, we discovered that CEP164 was highly associated with the expression state of GPC2, and mediated G2/M-phase arrest in GPC2-downregulated tumor cells. CONCLUSION: GPC2 might be a novel oncogenic gene in colorectal cancer, suggesting that it could be a considerable marker for the diagnosis and prognosis of colorectal cancer.

Artificial Intelligence [AI] has been a trendy topic in recent years, with many developed medical applications. In gastrointestinal endoscopy, AI systems include computer-assisted detection [CADe] for lesion detection as bleedings and polyps and computer-assisted diagnosis [CADx] for optical biopsy and lesion characterization. The technology behind these systems is based on a computer algorithm that is trained for a specific function. This function could be to recognize or characterize target lesions such as colonic polyps. Moreover, AI systems can offer technical assistance to improve endoscopic performance as scope insertion guidance. Currently, we believe that such technologies still lack legal and regulatory validations as a large sector of doctors and patients have concerns. However, there is no doubt that these technologies will bring significant improvement in the endoscopic management of patients as well as save money and time.

OBJECTIVE: Biopsy remains the gold standard for the diagnosis of Non-alcoholic fatty liver disease (NAFLD). To investigate the diagnostic value of FibroScan based on biopsy and range of cut-offs for steatosis and fibrosis, we explored the grade of steatosis and fibrosis. METHOD: A simultaneous search was performed on cohort studies published earlier than October 8, 2020,in the PubMed, Web of Science, Sinomed, CNKI, VIP, and WanFang databases. Next,we screened qualified studies. The data were mainly analysed in RevMan and complemented in STATA. RESULTS: The area under the receiver operating characteristic of FibroScan in identifying the stage of steatosis for ≥ S1 was 0.90 (sensitivity:89%; specificity:92%), that for ≥ S2 was 0.82 (sensitivity:89%;specificity:70%) and that for S3 was 0.79 (sensitivity:83%; specificity:63%).The area under the receiver operating characteristic of FibroScan in identifying the stage of fibrosis for ≥ F1 was 0.86 (sensitivity:81%;specificity:77%),that for ≥ F2 was 0.80 (sensitivity: 75%; specificity:82%), that for ≥ F3 was 0.94 (sensitivity:87%; specificity: 89%) and that for F4 was 0.97 (sensitivity: 94%; specificity:91%). CONCLUSION: FibroScan, a promising and cost-effective technique, can provide an accurate noninvasive approach for quantifying and staging hepatic steatosis and fibrosis in NAFLD, particularly for advanced fibrosis and cirrhosis. Further studies are needed to explore the relationship between steatosis and fibrosis based on the same group. Additionally, NASH is the key stage of NAFLD. Early diagnosis and intervention can help reduce the incidence of liver cirrhosis. However, no large study has investigated the significance of FibroScan in the diagnosis of NASH confirmed by pathology.

BACKGROUND AND STUDY AIM: Gastric endoscopic submucosal dissection (ESD) is a curative treatment for gastric neoplasm. A scheduled second-look endoscopy could be performed to prevent delayed post-ESD bleeding. However, no studies on the efficacy of second-look endoscopy for the prevention of early delayed post-ESD bleeding have been conducted. So, the aim of this study was to be the first to investigate the efficacy of immediate second-look endoscopy for the prevention of post-ESD bleeding. PATIENTS AND METHODS: The 266 gastric ESD cases were included. Immediate second-look endoscopy was defined as repeated upper endoscopy soon after complete hemostasis of the ESD site and specimen fixation. Early and late delayed bleeding were classified as before or after 24 h after the ESD, respectively. RESULTS: The 262 ESD cases were enrolled and divided into three groups: the immediate second-look (n = 79), scheduled second-look (n = 86), and no second-look (n = 97). Post-ESD bleeding occurred in 19 cases (7.3%). Of these, 13 (68.4%) were early delayed post-ESD bleeding. The immediate second-look endoscopy had a lower incidence of early delayed post-ESD bleeding compared to the groups without immediate second-look endoscopy, (3.8% vs. 0.8%, p = 0.009). In a multivariate analysis, immediate second-look endoscopy significantly reduced early delayed post-ESD bleeding (OR 0.39, p = 0.022). The resected specimen area ≥ 1,000 mm was an independent risk factor for early delayed post-ESD bleeding (OR 8.98, p = 0.010). However, the frequency of delayed post-ESD bleeding did not differ between the three groups. CONCLUSION: Immediate second-look endoscopy after gastric ESD may prevent early delayed post-ESD bleeding under certain circumstances.

Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease, comprising hepatic steatosis, and non-alcoholic steatohepatitis. Periodontal disease (PD) may be a risk factor for the evolution of liver cirrhosis. This study aimed to evaluate the association between NAFLD and PD.We searched in Pubmed, Scopus, Cochrane, and Lilacs databases with descriptors (Non-alcoholic Fatty Liver Disease OR (non-alcoholic AND Fatty Liver AND disease) OR Nonalcoholic Steatohepatitis) AND (Periodontal Disease OR Gingivitis OR Periodontitis) from January 2021 to September 2021. We selected, by the abstract, cross-sectional, cohort (prospective and retrospective), and case-control studies that address periodontal disease in patients with Non-alcoholic Fatty Liver Disease, and aged ≥ 18 years. The search was without the restriction of language and publication time.The search resulted in 954 articles. After applying the selection criteria, five cross-sectional studies remained. A metanalysis combined the study estimates of periodontal disease in NAFLD, by using the random effects. The Odds Ratio (1.91; 95% CI 1.21-3.02; P = 0.006) indicates that the chance of presenting Periodontal disease is 91% higher in individuals with NAFLD when compared with individuals without NAFLD. There are few studies with appropriate methodology to produce sound evidence about the causal relationship between the use of NAFLD and PD, however, studies support the association. So, dental staff must be aware of this association for better management of periodontal disease in patients with NAFLD.

BACKGROUND AND STUDY AIM: Fungi have a well-established role in medicine. Herein, we describe the fungal profile and abundance in the gut of healthy Saudi children. PATIENTS AND METHODS: Fecal samples from a random sample of 20 school-age Saudi children were collected, stored at -80 °C, and dispatched to the laboratory in the USA where fungal DNAs were isolated and shotgun metagenomic sequencing was performed. Abundance was presented as average percentage of fungal taxa. RESULTS: The median age of the participants was 12.5 years (range: 7-16 years), and 35 % were male. Ascomycota were the most abundant phyla and Eurotiomycetes, Saccharomycetes, were the most abundant class. The average abundance of fungal genera were Histoplasma (36 %) and Saccharomyces (31 %). The most abundant species were Histoplasma capsulatum (36 %) and Saccharomyces pastorianus (23 %). Other less abundant but may be functionally important genera and species included Candida (2.6 %) and Saccharomycescerevisiae (8 %). CONCLUSION: The profile and abundance of the gut fungi in healthy Saudi children reveals important differences compared to Western literature. Accordingly, this report represents a more appropriate reference than Western data to use as controls for regional studies aiming to identify fungi associated with disease.

Bleeding disorders can exacerbate gastrointestinal bleeding in inflammatory bowel disease (IBD) at the time of diagnosis or flares. Factor VII (FVII) deficiency is a life-threatening rare congenital bleeding disorder in childhood. This study describes three adolescent patients with IBD accompanied by acquired FVII deficiency. This is the first case series of patients with IBD accompanied by FVII deficiency. We hypothesized that inflammation, accelerated consumption, disease severity, and weight loss can cause decreased FVII activity in patients diagnosed with IBD. To control intestinal bleeding, we must keep in mind factor deficiencies in IBD.
