Posterior reversible encephalopathy syndrome is a rare syndrome characterized by brain edema and neurological symptoms, often resulting from several drugs. Treatment is based on discontinuation, and diagnosis is thus essential. Only 13 cases of posterior reversible encephalopathy syndrome have been reported in inflammatory bowel diseases, and we present the first after azathioprine in adults. A 56-year-old patient with active ulcerative colitis was found unconscious 5 days after the institution of azathioprine. Right-sided hemiplegia was found after the patient regained consciousness. Magnetic resonance imaging showed altered signal associated with diffusion restriction in the occipital lobe and cerebral vasogenic edema. Complete regression of neurological signs occurred after azathioprine discontinuation.Schistosomiasis is a trematode infection rarely diagnosed in the United States. Intestinal involvement is common with chronic infection and causes abdominal pain, changes in bowel habits, hematochezia, and polyp formation. Chronic, disseminated infection can affect the intestines causing the aforementioned symptoms, but reports of intestinal polyps are rare. check details Most cases are inflammatory fibrous polyps in the colon. There are very few cases reported in the literature of hamartomatous polyps arising in the small intestine. We present the rare case of a U.S.-born, 35-year-old woman diagnosed with a large duodenal hamartomatous polyp in the setting of intestinal schistosomiasis.
Inflammatory disease characterized by clinical destructive respiratory disorder is called acute lung injury/acute respiratory distress syndrome (ALI/ARDS). Studies have shown that luteolin exerts anti-inflammatory effects by increasing regulatory T cells (Tregs). In this study, we aimed to determine the effects of luteolin on ALI/ARDS and Treg differentiation.
In this paper, we used cecal ligation puncture (CLP) to generate an ALI mouse model to determine the effects of luteolin on ALI/ARDS. Lung tissues were stained for interleukin- (IL-) 17A and myeloperoxidase (MPO) by immunohistochemical analysis. The levels of Treg-related cytokines in serum and bronchoalveolar lavage fluid (BALF) of mice were detected. The protein levels of NF-
B p65 in lung tissues were measured. Macrophage phenotypes in lung tissues were measured using immunofluorescence. The proportion of Tregs in splenic mononuclear cells and peripheral blood mononuclear cells (PBMCs) was quantified. Furthermore,
, we evaluated the effects of M2 macrophages
. Luteolin-induced Treg differentiation from naïve CD4
T cells may be a potential mechanism for regulating IL-10 production.
Luteolin alleviated lung injury and suppressed uncontrolled inflammation by inducing the differentiation of CD4+CD25+FOXP3+ Tregs and upregulating the expression of IL-10. Furthermore, the anti-inflammatory cytokine IL-10 promoted polarization of M2 macrophages in vitro. Luteolin-induced Treg differentiation from naïve CD4+ T cells may be a potential mechanism for regulating IL-10 production.The occurrence of hepatocellular carcinoma (HCC) is closely related to the chronic inflammation which caused liver fibrosis and cirrhosis, and the interaction between HCC and its microenvironment further drives tumorigenesis. However, the single-cell resolution in vivo study is lacking, which limits our molecular understanding of tumour biology in the liver. Here, using published single-cell sequencing technology (scRNA-seq) database, we analyzed the liver microenvironment at high resolution in an unbiased manner and demonstrated the transcriptomic comparison between various cell populations and subpopulations in HCC and cirrhosis tissues. We found that eight genes that are specifically expressed in the endothelial cell and stellate cell of the HCC patients and correlated them with their survival rate, which may provide novel diagnosis and treatment targets for the clinical application.
Psoriasis (PA) is a chronic autoimmune disease of the skin that adversely affects patients' quality of life. Yangxue Jiedu Fang (YXJD) has been used for decades to treat psoriasis in China. However, its antipsoriatic mechanisms are still poorly understood. In this study, we explored the effects of YXJD on angiogenesis and apoptosis of microvessels in PA, the underlying mechanisms in HUVEC cells transfected by Survivin overexpression plasmid and in a mouse model of imiquimod-induced psoriasis and the relationship between VEGF (vascular endothelial growth factor) and Survivin.
A BALB/c mouse model of imiquimod- (IMQ-) induced PA was established, and the mice were treated with YXJD. Cell viability was assessed by CCK8 assay. Apoptosis was detected by annexin V-FITC/PI double-staining and caspase-3 assays. The PI3K/Akt/
-catenin pathway was analyzed by western blotting, ELISA, and immunochemical analysis.
YXJD ameliorated symptoms and psoriasis area and severity index (PASI) scores and also reduced the numo adjust apoptosis, autophagy, and angiogenesis of microvessels and thus improve the vascular sustainability in psoriasis. YXJD may represent a new direction of drug research and development for immunomodulatory therapy for psoriasis.Currently, no vaccine to prevent hepatitis C virus (HCV) infection is available. A major challenge in developing an HCV vaccine is the high diversity of HCV sequences. The purpose of immunization with viral glycoproteins is to induce a potent and long-lasting cellular and humoral immune response. However, this strategy only achieves limited protection, and antigen selection plays a crucial role in vaccine design. In this study, we investigated the humoral immune responses induced by intraperitoneal injection of keyhole limpet hemocyanin conjugated with 4 highly conserved peptides, including amino acids [aa]317-325 from E1 and aa418-429, aa502-518, and aa685-693 from E2, or 3 peptides from hypervariable region 1 (HVR1) of E2, including the N terminus of HVR1 (N-HVR1, aa384-396), C terminus of HVR1 (C-HVR1, aa397-410), and HVR1 in BALB/c mice. The neutralizing activity against HCV genotypes 1-6 was assessed using the cell culture HCV (HCVcc) system. The results showed that the 4 conserved peptides efficiently induced antibodies with potent neutralizing activity against 3 or 4 genotypes.
