Jing Du, Ying Wang, Yan-Chun Li, Tong-Tong Wang, Yong-Lie Zhou, Zhen-Hua Ying
Systemic lupus erythematosus (SLE) is an autoimmune disease that affects many organs, but multisystem dysfunction is rare. Here, we report a case of a 29-year-old woman who was initially diagnosed with SLE complications including lupus nephritis, lupus encephalopathy, renal hypertension, thrombocytopenia, anaemia and hyperkalaemia. She recovered following treatment with high dose methylprednisolone, intravenous immunoglobulin (IVIG) and continuous renal replacement therapy (CRRT). However, a few days after hospital discharge, she developed gastrointestinal bleeding...

The nuclear lamina is a multi-protein lattice composed of A- and B-type lamins and their associated proteins. This protein lattice associates with heterochromatin and integral inner nuclear membrane proteins, providing a link between the genome, nucleoskeleton, and cytoskeleton. In the 1990s, mutations in EMD and LMNA were linked to Emery-Dreifuss muscular dystrophy. Since then, the number of diseases attributed to nuclear lamina defects, including laminopathies and other disorders, has increased to include more than 20 distinct genetic syndromes...

MUC2 mucin is a large glycoprotein produced by goblet cells that forms the protective mucus blanket overlying the intestinal epithelium as the first line of innate host defense. High MUC2 production in inflammatory bowel disease and infectious colitis depletes goblet cells and the mucus layer by an unknown mechanism. Here, we analyzed the effect of high MUC2 biosynthesis on endoplasmic reticulum (ER) stress and apoptosis in goblet cells using a high MUC2-producing human goblet cell line (HT29-H) and a HT29-H clone (HT29-L) silenced for MUC2 expression by lentivirus-mediated shRNA...

Transthyretin-related Familial Amyloid Polyneuropathy (ATTR Amyloidosis, former FAP, here called TTR-FAP) is a rare, progressive autosomal dominant inherited amyloid disease ending fatal within 5 - 15 years after final diagnosis. TTR-FAP is caused by mutations of transthyretin (TTR), which forms amyloid fibrils affecting peripheral and autonomic nerves, the heart and other organs. Due to the phenotypic heterogeneity and partly not specific enough clinical symptoms, diagnosis of TTR-FAP can be complicated...

The factors that trigger the pathophysiology of Parkinson's disease (PD) are unknown. However, it is suggested that environmental factors, such as exposure to pesticides, play an important role, in addition to genetic predisposition and aging. Early signs of PD can appear in the gastrointestinal (GI) tract and in the olfactory system, preceding the onset of motor impairments by many years. The present study assessed the effects of oral rotenone administration (30 mg/kg) in inducing GI and olfactory dysfunctions associated with PD in mice...

Graft versus host disease (GVHD) following transplantation of an intestine-containing graft occurs more frequently than with other solid organ transplants and is known to have a poor outcome. The presentation differs from other solid organ transplants, as the gastrointestinal tract is not involved following intestinal transplant. Diagnosis is based on clinical symptoms arising due to native tissue damage and the detection of donor T lymphocytes in circulating blood (T cell chimerism). The ideal treatment strategy has not been defined, with advocates for both increased or decreased immunosuppression...

BACKGROUND: Interstitial cells of Cajal (ICC) serve as intestinal pacemakers. Postoperative ileus (POI) is a gastrointestinal motility disorder that occurs following abdominal surgery, which is caused by inflammation-induced dysfunction of smooth muscles and enteric neurons. However, the participation of ICC in POI is not well understood. In this study, we investigated the functional changes of ICC in a mouse model of POI. METHODS: Intestinal manipulation (IM) was performed to induce POI...

The human gut barrier is the tissue exposed to the highest load of microorganisms, harbouring 100 trillion bacteria. In addition, the gut's renewal rate outruns that of any other human tissue. Antimicrobial peptides (AMPs) are highly optimized defense molecules in the intestinal barrier optimized to maintain gastrointestinal homeostasis. Alterations in AMPs activity can lead to or result from human gastrointestinal diseases. In this review, unique, conserved, or otherwise regular alterations in the expression patterns of human AMPs across gastrointestinal inflammatory and infectious diseases were analyzed for pattern elucidation...

Gastrointestinal dysfunction is a common problem in the elderly. Aging-related changes in interactions between local dopaminergic and renin-angiotensin systems (RAS) have been observed in the brain, renal and vascular tissues. However, it is not known if these interactions also occur in the gut, and are dysregulated with aging. We showed a mutual regulation between the colonic dopaminergic system and RAS using young and aged mice deficient for major angiotensin and dopamine receptors. Aged rats showed a marked decrease in colonic dopamine D2 receptor expression, together with an increase in angiotensin type 1 (AT1) receptor expression, a decrease in angiotensin type 2 (AT2) receptor expression (i...

Stress is a powerful modulator of neuroendocrine, behavioral, and immunological functions. So far, the molecular mechanisms of response to stressors still remain elusive. In the current study, after 10 days of repeated chronic stress (hot-dry environment and electric foot-shock), a murine model of combined-stress (CS) was created in the SPF Wistar rats. Meanwhile, we established an ulcerative-colitis (UC) rat model induced by 2,4,6-trinitrobenzene sulfonic acid (TNBS)/ethanol enema according to previous studies...

Background and Objectives: Bidirectional signaling between the gastrointestinal tract and the brain is vital for maintaining whole-body homeostasis. Moreover, emerging evidence implicates vagal afferent signaling in the modulation of host physiology by microbes, which are most abundant in the colon. This study aims to optimize and advance dissection and recording techniques to facilitate real-time recordings of afferent neural signals originating in the distal colon. New Protocol: This paper describes a dissection technique, which facilitates extracellular electrophysiological recordings from visceral pelvic, spinal and vagal afferent neurons in response to stimulation of the distal colon...

Cisplatin (cis-diamminedichloroplatinum [II], CP) is most widely prescribed in chemotherapy and efficaciously treats diverse human cancers, with remission rates >90% in testicular cancers. However, clinical use of CP is associated with numerous untoward side effects, in particular, at the gastrointestinal level that reduces the therapeutic efficacy of CP and often results in withdrawal of its clinical usage in long term cancer chemotherapy. Substantial strides have been made to identify effective protective strategies against CP-induced nephrotoxicity, hepatotoxicity and ototoxicity...

Functional gastrointestinal disorders (FGIDs) are common among children and cause tremendous distress for patients and families. Family physicians should know how to diagnose and manage some of the more common childhood FGIDs. These include infant regurgitation, infant colic, infant dyschezia, cyclic vomiting syndrome, functional nausea and vomiting, functional diarrhea and constipation, abdominal migraine, and nonspecific functional abdominal pain. Diagnosis requires a thorough history and physical examination to rule out red flag signs and symptoms for structural or organic etiologies...

Spontaneous bacterial (SBP) and spontaneous fungal peritonitis (SFP) can be a life-threatening infection in patients with liver cirrhosis (LC) and ascites. One of the possible mechanisms of developing SBP is bacterial translocation. Although the number of polymorphonuclear cells in the culture of ascitic fluid is diagnostic for SBP, secondary bacterial peritonitis is necessary to exclude. The severity of underlying liver dysfunction is predictive of developing SBP; moreover, renal impairment and infections caused by multidrug-resistant (MDR) organism are associated with a fatal prognosis of SBP...

Chronic psychosocial stress at workplace is an important factor in the development of physical and mental illness. Objective biological measures of chronic stress are still lacking, but inflammatory response and growth factors are increasingly considered as potential stress biomarkers. Therefore, we investigated the relationship between psychophysical strain and serum levels of 48 chemokines, cytokines and growth factors measured using a multiplex immunoassay, and serum brain-derived neurotrophic factor (BDNF) measured by ELISA...
