Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous condition that predisposes to numerous proliferative lesions, including perivascular epithelioid cell tumors (PEComas), such as lymphangioleiomyomatosis (LAM) and angiomyolipomas, and rare neuroendocrine neoplasms. We describe herein a TSC2-harboring tuberous sclerosis patient manifesting with a synchronous well-differentiated L-cell rectal neuroendocrine tumor and leiomyomatosis-like LAM of the rectum. The background large bowel wall was thickened by confluent nodular areas comprising vessels and spindle-to-epithelioid cells, which are immunoreactive for myoid (smooth muscle actin, muscle specific actin, and desmin) and melanocytic markers (HMB45, Melan-A, microphthalmia transcription factor, and CD117)...

This study aimed to investigate the role of JNK pathway-associated phosphatase (JKAP) in inflammatory bowel disease (IBD). JKAP expression was analyzed in the intestinal mucosa of 81 IBD patients and 25 healthy controls (HCs) by qPCR and immunoblotting. The correlations of JKAP with clinical activity and inflammatory cytokines were performed. JKAP expression before and after infliximab treatment was also measured. CD4(+) T cells were isolated from peripheral blood in active IBD patient and HCs and transduced with lentivirus-encoding JKAP (LV-JKAP), anti-JKAP (LV-anti-JKAP), or empty vector (LV-scramble), and JKAP functions on IBD CD4(+) T cells were subsequently investigated...

OBJECTIVE: Most of the ovarian cancers are diagnosed at advanced stages. As peritoneal carcinomatosis increases, especially when it extends to the diaphragm and intestinal mesos, probability of obtaining complete cytoreduction is reduced. Complete cytoreduction (residue zero: R0) is one of the main factors affecting survival [1-3]. Here we present a novel technique of stripping the peritoneal surfaces as a part of cytoreductive surgery in such cases. METHODS: A 55year-old woman diagnosed with peritoneal carcinomatosis was considered appropriate for primary cytoreduction after assessment of her thorax-abdominopelvic tomography, which revealed resectable intra-abdominal disease...

A single-band protein (HEP3) was isolated from Hericium erinaceus using a chemical separation combined with pharmacodynamic evaluation methods. This protein exhibited immunomodulatory activity in lipopolysaccharide-activated RAW 264.7 macrophages by decreasing the overproduction of tumor necrosis factor-α, interleukin (IL)-1β, and IL-6, and downregulating the expression of inducible nitric oxide synthase and nuclear factor-κB p65. Further researches revealed that HEP3 could improve the immune system via regulating the composition and metabolism of gut microbiota to activate the proliferation and differentiation of T cells, stimulate the intestinal antigen-presenting cells in high-dose cyclophosphamide-induced immunotoxicity in mice, and play a prebiotic role in the case of excessive antibiotics in inflammatory bowel disease model mice...

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and Ulcerative Colitis (UC), are immune mediated conditions associated with progressive damage of the inflamed gut tissue, and have a considerable impact on the patient's quality of life. The pathogenesis remains uncertain, but it is clear that complex mechanisms associated with host and luminal factors are involved, generating an unbalance between pro- and anti-inflammatory signaling. It is well established that the purpose of an adequate and complete control of the intestinal inflammation measured not only by clinical symptoms, but also with more objective data such as fecal biomarkers (calprotectin) and endoscopy...

Numerous studies have demonstrated that free Ig light chain (FLC), a novel inflammation mediator, participates in many inflammatory diseases by activating mast cells and extending the survival of neutrophils. However, it remains unclear whether FLC is involved in colitis and colitis-associated colon carcinogenesis (CAC). In this study, we found a significant increase in FLC in murine models of DSS (Dextran Sulfate Sodium Salt)-induced colitis and CAC compared to controls. Peptide F991, a functional blocker of FLC, significantly attenuated colitis progression, which included abrogating the development of diarrhea and tumor burden, elevating survival rate, greatly reducing the infiltration of inflammatory cells (such as ROS(+) active neutrophils), especially reducing tumorigenesis in CAC...

For many patients with GI malignancies, the seeding of the abdominal cavity with tumor cells, called peritoneal carcinomatosis, is a common mode of metastases and disease progression. Prognosis for patients with this aspect of their disease remains poor, with high disease-related morbidity and complications. Uniform and proven practices that provide optimal palliative care and quality of life for these patients are needed. The objective of this review is to critically assess the current literature regarding palliative strategies in the management of peritoneal carcinomatosis and associated symptoms in patients with advanced GI cancers...

The application value of small intestine decompression combined with oral feeding in the middle and late period of malignant small bowel obstruction was examined. A total of 22 patients with advanced malignant small bowel obstruction were included in the present study. An ileus tube was inserted via the nose under fluoroscopy into the obstructed small intestine of each patient. At the same time, the insertion depth the of the catheter was adjusted. When the catheter was blocked, small bowel selective angiography was performed to determine the location and cause of the obstruction and the extent of the obstruction, and to determine the length of the small intestine in the site of obstruction, and to select the variety and tolerance of enteral nutrition...

PURPOSE OF REVIEW: After expiry of the patent of originator anti-tumor necrosis factor drug infliximab (Remicade), CT-P13 was in 2013 the first infliximab biosimilar to be approved by the European Medicine Agency (EMA) for the same indications as the reference drug, including paediatric inflammatory bowel disease (IBD). The approval was based on extrapolation, after extensive in-vitro studies and clinical experience in patients with ankylosing spondylitis and rheumatoid arthritis. The extrapolation of CT-P13 to IBD and to paediatric patients raised concerns among paediatric IBD specialists...

Inflammatory bowel disease (IBD) is idiopathic, lifelong, immune-mediated diseases, for which curative therapies are not yet available. In the last 15 years, the introduction of monoclonal antibodies targeting tumor necrosis factor-α, a cytokine playing a key role in bowel inflammation, has revolutionized treatment paradigms for IBD. Despite their proven long-term efficacy, however, many patients do not respond or progressively lose response to these drugs. Major advances of knowledge in immunology and pathophysiology of intestinal inflammatory processes have made possible the identification of new molecular targets for drugs, thus opening several new potential therapeutic opportunities for IBD...

Modern medical practice has resulted in the accumulation of a growing number of incurable chronic diseases, many of which are inflammatory in nature. Inflammation establishes a hypoxic microenvironment within tissues, a condition of inflammatory hypoxia (IH). Tissues thus affected become severely compromised, are unable to elicit adaptive responses and eventually develop fibrosis and fixed microvascular deficits. Previous work has demonstrated that tissue hypoxia exits even within the simple human model of self-resolving inflammation, the tuberculin reaction...

The consensus molecular subtypes (CMS) in colorectal cancer (CRC) represent distinct molecular subcategories of disease as reflected by comprehensive molecular profiling. The four CMS subtypes represent unique biology. CMS1 represents high immune infiltration. CMS2 demonstrates upregulation of canonical pathways such as WNT signaling. Widespread metabolic changes are seen in CMS3. CMS4 represents a mesenchymal phenotype with hallmark features including complement activation, matrix remodeling, angiogenesis, epithelial-mesechymal transition (EMT), integrin upregulation and stromal infiltration...
