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.

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.

Objective:To investigate the value and effectiveness of the case-based learning assisted by several internet platforms for medical interns in interactive teaching for undergraduate students in the clerkship of cardiovascular surgery.Methods:Ninety-six undergraduates were randomly divided into control group ( n = 48) and experiment group ( n = 48). The control group received traditional teaching, and the experiment group received case-based learning with the aid of WeChat and Sojump questionnaires. The theoretical and clinic operating scores, classroom atmosphere, learning interest, learning efficiency, learning ability improvement, theoretical knowledge mastery and clinical skills improvement were were compared between the two groups. SPSS 19.0 was used for t test and chi-square test. Results:The clinic operating scores, classroom atmosphere, learning interest, learning efficiency, learning ability improvement, theoretical knowledge mastery and clinical skills improvement were statistically higher in experiment group than in control group ( P < 0.05). Conclusion:The application of case-based learning combined with internet platforms has achieved a good teaching effect in interactive teaching for undergraduate students in the clerkship of cardiovascular surgery and is worthy of popularizing.

The ever increasing use of the Single-use medical devices(SUD) in clinic has brought safety and convenience to people, while the management of SUD waste also put pressure on the environment. Reprocess and reuse of SUD has become the issue of social concerns. This paper will describe the management manner of FDA for reprocess and reuse of SUD, and then give some suggestion on China's management combining the national conditions of our country.

The ever tenser physician-patient relationship is one of major social problems in present China,thus the construction of a harmonious physician-patient relationship is one important part in constructing a harmonious society.Medical social workers' involvement into the current physician-patient relationship from the perspectives of case social work,group social work,community social work,and social policy making will serve as a positive motivation for the development of a harmonious physician-patient relationship.

Objective:To investigate and analyze the rational use of anti-tumor immune enhancement drugs in our hospital. Meth-ods:The annual use data of anti-tumor immune enhancement drugs in our hospital in 2015 were collected, and then statistically ana-lyzed and evaluated combing with the medical history information. Results: There were 12 varieties and 19 specifications of adjuvant anti-tumor immune enhancement drugs in our hospital, which accounted for 15. 87% of the total sum. Totally 25 481 patients used ad-juvant anti-tumor immune enhancement drugs, which occupied 29. 84% of the total medicine afford. The adjuvant anti-tumor immune enhancement drugs showed lots of irrational use in clinics, and the main irrationity was overuse and off-label use. Conclusion: It is necessary to strengthen prescription evaluation for anti-tumor immune enhancement drugs, which needs controlled and rational use.

Objective:To investigate the distribution of infection pathogens and their drug resistance in acute severe pancreatitis patients. Methods:Retrospective analysis was made on all pathogenic bacteria and their drug resistance of infection among 78 patients with acute severe pancreatitis patients. Results:Among 78 patients with acute severe pancreatitis 75 patients were cured,3 patients were dead.Of 286 clinical isolates,Gram negative organisms accounted for 61.19%,Gram positive ones 32.17%,fungi(6.64%).They resisted to antibiotics at high degrees.Among 92 strains of gram positive organism,60 were drug-resistance;also 172 strains of gram negative organism,above half were drug-resistance. Conclusion:Patients with acute severe pancreatitis are at high risk of infection.Due to drug-resistance are at high degrees in infection pathogens,effective drainage should be adopted to accelerate treating the infection besides selecting correct antibiotics according to the antibiotic sensitive essay results.

Objective:To explore the clinical diagnosis,therapy and pathologic characteristics of primary bilateral breast cancer in order to improve the survival of breast cancer patients.Methods:Eleven cases of primary bilateral breast cancer patients were retrospective analysised.Results:Among the 11 cases of primary bilateral breast cancer patients,2 cases were dead for multi organ metastasis;9 cases survived.Among which one has been alive for 6 years after operation.Conclusion:The early diagnosis and treatment of the second primary cancer remain the key factor to improve the outcome of the bilateral breast cancer patients.

The incidence of breast cancer has markedly increased in recent years.Breast cancer has become a major cause of death of adult females.Many studies have shown that glucose metabolism disorders and its connected factors have been closely related to occurrence and development of breast cancer.Regulation of glucose metabolism and related factors may become an important way in prevention and treatment of breast cancer.
