Objective To observe the therapeutic effect of heat-clearing and dampness-removing therapy combined with Bifico for ulcerative colitis ( UC) induced by trinitrobenzene sulfonic acid ( TNBS), and to explore its influence on tumor necrosis factor alpha ( TNF-α) and interleukin-10 ( IL-10) in rats. Methods Forty female adult Sprague-Dawley rats were evenly randomized into five groups, namely normal control group, model group, Bifico (175 mg/kg) group, Chinese medicine group(enema with Changdiqing 3.6/kg and oral use of Changyanling Recipe l) , and Chinese medicine plus Bifico group. After treatment, the damage of colonic mucous membrane was evaluated, and expression levels of IL-10 and TNF-α in colonic mucosa were observed through immunohistochemical assay. Results The degree of colonic mucosal injury was severer and the inflammation was more obvious in the model group than those in the normal control groups ( P<0.01) , and the above changes were relieved to various degrees in the medication group ( P<0.01 compared with those in the model group) . Chinese medicine plus Bifico group had better effect on reducing colonic mucosa damage index ( CMDI) and inflammation, and on promoting the healing of colonic mucosa than Bifico group and Chinese medicine group (P<0.05 ) . The expression level of TNF-α in the colonic mucosa was markedly increased while that of IL-10 was markedly decreased in the model group ( P<0.01 compared with those in the normal control group) . The medication groups could counteract the above changes in the colonic mucosa ( P<0.01 compared with those in the model group) . The combination group and Chinese medicine group had better effect on decreasing TNF-α expression level and on increasing IL-10 expression level than Bifico group ( P<0.05) . Conclusion IL-10 and TNF-α play an important role in the pathogenesis and development of ulcerative colitis. Chinese medicine combined with Bifico has satisfactory therapeutic effect on UC rats, and its mechanism may be related with the increase of IL-10 expression level and with the decrease of TNF-α expression level.

Objective:To explore the key genes related to the development, progression and prognosis of acute myeloid leukemia (AML) based on bioinformatics, and to analyze their functions.Methods:The chip expression profile GSE84881 data set of AML patients including 19 AML samples and 4 normal tissue samples was downloaded from the gene expression omnibus (GEO) database. GEO online tool GEO2R was used to screen the differentially expressed genes (DEG). The DAVID online database was used to make gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis of DEG. The STRING online database was used to analyze the protein interaction (PPI) network of DEG, and the key genes were screened by using the Cytoscape software. The weighted gene co-expression network analysis (WGCNA) was used to build co-expressed network and obtain the central genes.LC-Bio online platform was used to construct Venn diagram and the key genes and central genes in PPI were crossed to finally obtain the true key genes. RNA-seq datasets GSE2191 and GSE90062 of human tissues were downloaded from GEO database to verify the screened key genes. Kaplan-Meier method was used to analyze the effects of key genes on the overall survival (OS) of AML based on the data of GEPIA database.Results:A total of 247 DEG were identified in GSE84881 data set, including 112 up-regulated genes and 135 down-regulated genes. According to the results of GO enrichment analysis, 247 DEG were mainly enriched in the regulation of signal transduction and cell proliferation in the biological process (BP); the cell composition (CC) revealed that these genes were mainly involved in the cytoplasm and exosomes; the molecular function (MF) analysis showed that these genes were mainly enriched in protein binding and calcium binding. Further KEGG pathway enrichment analysis showed that these 247 DEG were mainly involved in NOD-like receptor signal pathway and interleukin 17 (IL-17) signal pathway. And then the 12 key genes were obtained from PPI. WGCNA software was used to screen 13 central genes from GSE84881 dataset and finally 1 real key gene EGF was obtained after taking intersection. Kaplan-Meier method showed that OS time of AML patients in EGF high expression group was decreased than that in EGF low expression group, and the difference was statistically significant( P = 0.044). Conclusions:EGF may be an important diagnosis and treatment target of AML and may become a potential biomarker for clinical treatment and prognosis prediction of AML.

PURPOSE: Adenoid cystic carcinoma (ACC) of the trachea and bronchus is a rare tumor. Although MYB-NFIB oncogene fusion and Notch1 mutation have been identified in ACC, little is known about the expression and clinical significance of Notch1 and its target gene fatty acid binding protein 7 (FABP7) in tracheobronchial ACC. MATERIALS AND METHODS: Primary tracheobronchial ACC that were resected between 1998 and 2014 were identified through the pathology and oncology database from five thoracic oncology centers in China. A tissue array was constructed from the patients’ samples and the expressions of Notch1 and FABP7 were evaluated by immunohistochemistry. The association between the expression of both markers and survival was determined. RESULTS: Overexpression of Notch1 and FABP7, detected in 37.8% and 38.3% of 368 patients with tracheobronchial ACC, respectively, was an independent prognostic indicator for recurrencefree survival (RFS) by multivariable Cox proportional hazard model (p=0.032 and p=0.048, respectively). Overexpression of Notch1, but not of FABP7, predicted overall survival (OS) (p=0.018). When categorized into four groups according to coexpression of Notch1 and FABP7, patients with overexpression of both Notch1 and FABP7 belonged to the group with the shortest RFS and OS (p=0.01 and p=0.048, respectively). CONCLUSION: Expression of Notch1 and FABP7, and coexpression of Notch1 and FABP7, is strongly associated with poor survival in resected tracheobronchial ACC. These data are consistent with the hypothesis that poor differentiation of tracheobronchial ACC correlates with the activation of Notch signaling.

Objective To provide scientific evidence to identify and confirm severe acute respiratory syndrome (SARS) by laboratory detection.Methods Multiple clinical specimens were collected serially and systematically from the 4 suspected SARS patients, which occurred between Dec.2003 to Jan.2004 in Guangdong Province. The samples were tested by serologic and molecular methods.Results IgM or IgG antibodies against SARS-CoV were detectable after 6—8 days of the onset in four patients. The four-fold or greater rising in antibodies was clearly detected in three of the four patients, while the fourth patient’s seroconversion was from negative to positive. The results analysed by enzyme-linked immunosorbent assay( ELISA), immunoflourescence assay (IFA), and neutralization test were highly correlated. SARS-CoV RNA was just detected in 3 throat swab specimens from case 1 by real-time PCR. M, N and S genes were amplified by reverse transcriptase polymerase chain reaction (RT-PCR) from the positive samples. Sequencing results showed that they were SARS-CoV gene segments, and most closely matched SARS-CoV gene sequences were isolated from civet cats in Guangdong Province. Nevertheless, SARS-CoV was not isolated from any samples of the 4 patients.Conclusion Based on these results, the 4 reported cases were laboratorily confirmed as SARS cases.
