Interferon regulatory factors(IRF)are key factors in interferon induction. IRF4, a member of the IRF family of transcription factors, is expressed in cells of the immune system where it transducers signals from various receptors to activate or repress gene expression. IRF4 expression is a key regulator for the development T helper cell subsets and B lymphocyte differentiation. A series of recent studies have further demonstrated critical functions for IRF4. This review focuses on the recent advances on roles of IRF4, including infection, autoimmune disease and immune malignancy. A better understanding of IRF4 will hopefully provide new biomark and potentially guide the design of novel therapeutic approaches.

MicroRNAs (miRNAs) are small non-coding RNA molecules that negatively regulate gene expression.The miRNAs regulate gene expression by controlling the translation of a specific type of messenger RNA.miRNAs are key epigenetic regulators of gene expression,and miRNAs have been recently identified as key regulatory RNAs with immense significance in numerous biological processes.They actively participate in the modulation of important cell physiological processes and are involved in the pathogenesis of asthma.MiRNAs have been implicated to have a fundamental role in acute and chronic asthma and in airway remodeling by the regulation of multiple signal transduction pathways that are involved in the pathogenesis of asthma.A better understanding of the role that miRNAs play in the diseases could lead to the development of new diagnostic and therapeutic tools.This review highlights the current understanding of the role and regulation of miRNA in asthma.

OBJECTIVETo study the effect of nadroparin in the migration of breast cancer cells MDA-MB-231 and its action mechanism.

METHODThe MTT test was adopted to observe the effect of different concentrations of naringenin on the growth capacity of breast cancer cells MDA-MB-231. Wound healing and transwell experiment analysis were conducted to detect the effect of naringenin on the migration of breast cancer cells MDA-MB-231. Western blotting was adopted to investigate the effect of naringenin on protein expressions of MDA-MB-231 cell Integrin β3, β1 and matrix metalloproteinase MMP-2 and MMP-9. The computer virtual docking technique was used to evaluate the combining capacity of naringenin and Integrin β3 in vitro.

RESULTNaringenin inhibited the migration of MDA-MB-231 cells in a dose-dependent manner. In wound healing and transwell experiments, with the increase in the concentration of naringenin, the number of migrant MDA-MB-231 cells and the invasion capacity of breast cancer cells decreased. Naringenin could inhibit the protein expression of Integrin β3 in a dose-dependent manner, but with unobvious effect on expression of Integrin β1. Besides, naringenin could significantly inhibit the protein expressions of MMP-2 and MMP-9. The results of the computer virtual docking showed a negative value in the combining capacity between naringenin and Integrin β3, indicating the high affinity between them.

CONCLUSIONNaringenin can inhibit the growth capacity of breast cancer cells MDA-MB-231 and block the migration and invasion of breast cancer cells MDA-MB-231. Its mechanism is to down-regulate MMP-2 and MMP-9 expressions after combining with Integrin β3.

Background:Some functional dyspepsia(FD)patients are accompanied by sleep disorder,which severely affects the quality of life. Aims:To explore psychological factors and quality of life of FD patients with sleep disorder. Methods:A total of 240 FD patients from Jan. 2013 to Jan. 2014 at the Second Affiliated Hospital of Xi’an Jiaotong University and the Affiliated Hospital of Yan’an University were enrolled,and were divided into sleep disorder group and non-sleep disorder group according to Pittsburgh sleep quality index. Zung’s self rating anxiety scale,Zung’s self rating depression scale and SF-36 quality of life questionnaire were performed in all the patients. Results:Compared with non-sleep disorder group, the incidence of anxiety(72. 5% vs. 40. 8% )and incidence of depression(65. 0% vs. 37. 5% )were significantly higher in sleep disorder group(P < 0. 05). Score of physical function(86. 65 ± 3. 84 vs. 88. 88 ± 4. 56),vitality(44. 79 ± 18. 13 vs. 54. 63 ± 9. 63),mental health(46. 90 ± 11. 47 vs. 63. 42 ± 17. 60),general health(42. 79 ± 11. 07 vs. 58. 29 ± 14. 99)in sleep disorder group were significantly lower than those in non-sleep disorder group,and no significant differences in physical role function,emotional role function,social role function,and body pain were found between the two groups(P > 0. 05). In patients with sleep disorder,the incidence of mental disorder was significantly different among young age group,middle age group and old age group(50. 0% ,55. 0% ,80. 0% ,respectively)(χ2 = 8. 10,P < 0. 05), and the incidence of mental disorder in male patients was significantly lower than that in female patients(32. 6% vs. 79. 2% ;χ2 = 25. 62,P < 0. 05). Conclusions:FD patients with sleep disorder has its own clinical characteristics. Study on the clinical characteristics of FD patients with sleep disorder could facilitate the effectiveness therapy,and has important significance in improving the quality of life.
