ABSTRACT
Background: The prevalence of inflammatory bowel disease (IBD) is increasing worldwide, and anemia, one of the most prevalent extraintestinal manifestations of IBD, is still often underdiagnosed and undertreated. Aims: To analyze the correlations of clinical factors with anemia in patients with ulcerative colitis (UC). Methods: A retrospective analysis was conducted in 60 cases of UC admitted from September 2019 to May 2020 at the Second Affiliated Hospital of Zhengzhou University. Sixty healthy subjects were served as controls. Data of fasting venous blood sample analysis on admission were collected, and the correlations of indicators for anemia with the clinical factors were analyzed. Results: The indicators for anemia, including red blood cell (RBC) count, hemoglobin (Hb), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) etc. were significantly decreased in UC patients than in healthy controls (all P<0.05). RBC was lower in females than in males (P<0.05); RBC and HCT were lower in patients with pancolitis than in those with proctitis or left hemi-colon colitis (all P<0.05); RBC, Hb and HCT were lower in severe active UC than in mild active UC (all P<0.05). RBC, Hb, HCT and MCH were negatively correlated with two disease activity indicators for IBD, C-reactive protein (CRP) and/or erythrocyte sedimentation rate (ESR) (all P<0.05). Conclusions: Gender, as well as the disease extent, activity and severity are important clinical factors for anemia in patients with UC.
ABSTRACT
MicroRNAs (miRNAs) are a group of short non-coding RNAs consisting of about 22 nucleotides that downregulate gene expression at posttranscriptional level through binding to the 3'-untranslated region (3'-UTR) of target mRNAs. With the increase in research about miRNAs, it is found that miRNAs could modulate the differentiation and secretion of immunocytes as well as the function of intestinal mucosal barrier. Besides, miRNAs could regulate the composition of intestinal microbiome, and could be used as crucial biomarkers for the diagnosis of inflammatory bowel disease (IBD). In this paper, the roles of miRNAs in the pathogenesis of IBD were reviewed through intestinal immunity and barrier function.
ABSTRACT
Exosomes are extracellular vesicles with a diameter of 30-150 nm, which exist in multi-vesicular bodies in the form of intraluminal vesicles. Exosomes can be secreted by a variety of immune cells. Studies have shown that exosomes might play an important role in IBD through their components, such as annexin-A1 (ANXA1), the miRNAs and lipids. As a carrier of antigen presentation, it can affect the signaling pathways related to IBD, regulate the immune response and intestinal homeostasis. This article reviewed the relationship between exosomes and IBD.
ABSTRACT
Objective To develop a MOSAIQ Integration PlatformCHN (MIP) based on the workflow of radiotherapy (RT) and to meet the actual requirements in China and the special needs for the radiotherapy department.Methods MIP used C/S (client-server) structure mode running on the local network in the hospital and its database was based on the Treatment Planning System (TPS) and MOSAIQ database.Five network servers,as the core hardware,supplied data storage and network service based on cloud services.The core software was developed based on Microsoft Visual Studio Platform using C# network programming language.The MIP server could simultaneously offer network service for about 200 workstations,including entry,query,statistics,and print of data.Results MIP had 15 core function modules,such as Notice,Appointment,Billing,Document Management (application/execution),and System Management,which almost covered the whole workflow of radiotherapy.Up to June 2016,the recorded data in the MIP were as follows:13546 patients,13533 plan application forms,15475 RT records,14656 RT summaries,567048 billing records,and 506612 workload records.Conclusions The MIP based on the RT workflow has been successfully developed and used in clinical practice.It is an important part of radiotherapy information system construction with the advantages of intuitive operation,real-time performance,data security,and stable operation.It is digital,paperless,user-friendly,and convenient for the retrieval and statistics of data as well as information sharing and department management,and can significantly improve the efficiency of the department.More functions can be added or modified to enhance its potentials in research and clinical practice.
ABSTRACT
OBJECTIVE To investigate the expression of transcription factors Snail,Slug and cell adhesion molecule E-cadherin in nasopharyngeal carcinoma(NPC)and evaluate their relationship with clinical pathological features and metastases.METHODS Immunohistochemistry and quantitative polymerase chain reaction were carried out to detect the expression of Snail,Slug and E-cadherin in 65 NPC samples and normal nasopharyngeal mucosa(18 cases).The expression of Snail and Ecadherin in distinct differentiation nasopharyngeal carcinoma was analyzed and the relationship of them with clinical pathological features was discussed.RESULTS Real-time PCR analysis and immunohistochemistry showed that Slug was elevated with increasing tumor grade.E-cadherin expression was reduced corresponding with prognostic indices and tumor.Snail showed no obvious change.The relative expression levels of E-cadherin mRNA were significantly different between lymph node metastasis group and nometastasis group(P
