In children without malignancy, diagnostic accuracy of shivering was poor.Conclusion Shivering is of limited use to diagnose serious bacterial infection in children without malignancy. Nevertheless, in children with known malignancy, it can be useful as an alarm signal. What is Known • In the NICE guidelines for febrile illness in children, "shivering" is considered as an intermediate risk factor ("amber" sign) for a serious illness. • A systematic literature search conducted in 2007 investigating the correlation between shivering in a febrile child and the presence of a serious bacterial infection could include only one study. What is New • Based on the results of this systematic review, shivering has little diagnostic value in children without malignancy but can be useful as an alarm sign of serious bacterial infection in children with known malignancy. • In case of absence of shivering, serious bacterial infection cannot be ruled out.The present study aimed to investigate whether microRNA (miR)‑31 exerted therapeutic potential in allergic rhinitis (AR) and to explore its underlying mechanism. Firstly, the expression levels of miR‑31 were detected by reverse transcription‑quantitative PCR in the nasal mucosa of patients and mice. Subsequently, an ovalbumin (OVA)‑induced animal model of AR was constructed. Allergic symptom score, histopathological characteristics, OVA‑specific immunoglobulin E (IgE) titers, and T‑helper (Th)1 and Th2 cell‑related cytokine levels were analyzed in OVA‑sensitized mice, miR‑31‑overexpressing mice, miR‑negative control mice and control mice. Furthermore, interleukin (IL)‑13‑stimulated nasal epithelial cells (NECs) were used to assess the effects of miR‑31 on the production of IL‑13‑induced inflammatory cytokines and mucin 5AC by performing western blotting and ELISA. The expression levels of miR‑31 were significantly decreased in the nasal mucosa of the AR group compared with those in the control group. Moreover, upregulation of miR‑31 markedly attenuated sneezing and nasal rubbing events, reduced nasal eosinophil infiltration and goblet cell hyperplasia, and decreased the levels of OVA‑specific IgE and Th2‑related cytokines. In addition, subsequent experiments showed that upregulation of miR‑31 inhibited IL‑13 receptor α1 chain expression and signal transducer and activator of transcription 6 phosphorylation in NECs. Furthermore, miR‑31 suppressed IL‑13‑induced expression of thymic stromal lymphopoietin, granulocyte‑macrophage colony‑stimulating factor, eotaxin and mucin 5AC in NECs. In conclusion, these data revealed that miR‑31 could ameliorate AR by suppressing IL‑13‑induced nasal epithelial inflammatory responses, and thus may serve as a novel therapeutic target for AR.The purpose of the present study was to identify aberrantly expressed genes for gallbladder cancer based on the annotation analysis of microarray studies and to explore their potential functions. Differential gene expression was investigated in cholesterol polyps, gallbladder adenoma and gallbladder cancer using microarrays. Subsequently, microarray results were comprehensively analyzed. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to determine the affected biological processes or pathways. Differentially expressed genes (DEGs) of cholesterol polyps, gallbladder adenoma and gallbladder cancer were identified. Following comprehensive analysis, 14 genes were found to be differentially expressed in the gallbladder wall of both gallbladder cancer and gallbladder adenoma. The 20 most significantly upregulated genes were only upregulated in the gallbladder wall of gallbladder cancer, but not in the gallbladder wall of cholesterol polyps and gallbladder adenoma. In addition, 182 DEGs were upregulated in the gallbladder wall of gallbladder adenoma compared with the gallbladder wall of cholesterol polyps. A total of 20 most significant DEGs were found in both the tumor and gallbladder wall of gallbladder cancer. In addition, the most significant DEGs that were identified were only upregulated in the tumor of gallbladder cancer. Selleckchem Filgotinib GO and KEGG analysis indicated that the aforementioned DEGs could participate in numerous biological processes or pathways associated with the development of gallbladder cancer. The present findings will help improve the current understanding of tumorigenesis and the development of gallbladder cancer.Calcitonin gene‑related peptide (CGRP) is the predominant neurotransmitter located in sensory nerves. This peptide is extensively distributed in central and peripheral tissues. CGRP causes relaxation of cardiovascular smooth muscle cells and confers protection against ischaemic myocardium and cardiac remodeling. The pharmacological effects of nitroglycerine and rutaecarpine have been demonstrated to be associated with an increase in the synthesis and release of CGRP. In the gastrointestinal tissues, CGRP participates in the regulation of gastrointestinal function, and exerts protective effects on gastric mucosa. Rutaecarpine, capsaicin and its derivatives, such as evodiamine, decrease gastric mucosal damage induced by several factors, including increased synthesis and release of CGRP. Taken together, this review focuses on the pharmacological effects of several CGRP related canonical drugs and suggests that synthesis and secretion of CGRP exhibit significant therapeutic effects in the occurrence and development of cardiovascular and gastrointestinal diseases.Rheumatic heart disease (RHD) is an autoimmune disease caused by rheumatic fever following group A hemolytic streptococcal infection and primarily affects the mitral valve. RHD is currently a major global health problem. However, the exact pathological mechanisms associated with RHD‑induced cardiac valve damage remain to be elucidated. The endothelial‑mesenchymal transition (EndMT) serves a key role in a number of diseases with an important role in cardiac fibrosis and the activin/Smad2 and 3 signaling pathway is involved in regulating the EndMT. Nevertheless, there are no studies to date, to the best of the authors' knowledge, investigating the association between RHD and EndMT. Thus, the aim of the current study was to investigate the potential role of EndMT in cardiac valve damage and assess whether activin/Smad2 and 3 signaling was activated during RHD‑induced valvular injury in a rat model of RHD induced by inactivated Group A streptococci and complete Freund's adjuvant. Inflammation and fibrosis were assessed by hematoxylin and eosin and Sirius red staining.
