microRNA (miRNA) is a class of endogenous small non-coding RNA (20-25 nt) which can regulate the expression of protein-coding genes post-transcriptionally and participate in a series of critical biological processes including cell proliferation,differentiation,metabolism,apoptosis,et al.Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma subtype.DLBCL is defined as the malignant lymphoma which originates from the B cells,with aggressive clinical behaviors and significant clinical heterogeneity.In recent years,the researches on miRNA in DLBCL have shown that several kinds of miRNA directly involved in the occurrence and development of tumors and there is a correlation between the miRNA expression profiles and molecular subtypes of DLBCL.As a kind of new molecular target,miRNA has a broad prospect in the application both for diagnosis and biotherapy of DLBCL.

Objective] The article summarizes the experience of using sanren decoction to treat pediatric diseases by Professor Liu Lin, the famous TCM physician of Hubei. [Methods] Through following Professor Liu Lin clinical diagnosis, organize his medical records, summarize the experience and thoughts of using Sanren decoction to treat pediatric diseases, and for some cases. [Results] Professor Liu Lin believes that the physiological and pathological characteristics of children prone to cause hot and humid accumulation, pediatric Chih-Yin is not substantial, with their lungs often delicate and spleens often inadequate, they prone to get hot and humid accumulation after sick, and later appear a variety of symptoms including upper burner, center burner and lower burner. Therefore, the treatment of pediatric disease should take the heat into account, bearing in mind the residence site of heat evil and syndrome differentiation. Professor Liu Lin makes good use of Sanren decoction to treat a variety of pediatric diseases, judging the residence site of heat evil and clinical manifestations, giving the corresponding treatment flexibly. Such as the treatment of bronchitis with almonds as the monarch herb to expectorant cough, treatment of infantile anorexia with White Kou Ren as the monarch herb to activate spleen and remove dampness, treatment of children with nephrotic syndrome with Yiyiren as the monarch herb for penetration of water, treatment of HFMD with the Sanren to regulate Qi of triple burner, according to the symptoms to medicate and always has good clinical effect. [Conclusion] Professor Liu Lin using Sanren decoction to treat pediatric diseases is effective, his thought is worthy of depth study and promotion.

Objective:To study the inhibitory effects of adenovirus mediated vascular endothelial cell growth inhibitor 151(VEGI_(151)) on venous endothelial cell proliferation. Methods: VEGI_(151) gene was cloned into adenovirus vector pCA13 and the product was packaged and amplified with 293A cells.The expressed protein was identified by Western blot. X-gal staining was used to determine the transfection efficiency of the recombinant adenovirus system. The inhibitory effect of Ad-VEGI_(151) on ECV304 cell proliferarion was observed and assessed by violet crystal assay. The protein expression of VEGI_(151) gene in ECV304 cells was detected by immunohistochemistry. Results: Liposome-mediated pCA13-VEGI_(151) and pJM17 cotransfection of 293A cells (through homologous recombination of intracellular plasmid) is a practical and feasible method to obtain high-titre recombinant adenovirus. The constructed Ad-VEGI_(151), with high transfection efficiency, significantly inhibited ECV304 cells proliferation and expressed functional protein in target cells. Conclusion: Ad-VEGI_(151) can express bioactive protein in target cells and can inhibit the proliferation of venous endothelial cells, and this may pave a new way for gene therapy of tumors and neovascular diseases.

The quasispecies nature of hepatitis B and C virus (HBV, HCV) plays an important role in the pathogenesis, immune escape and drug resistance during chronic infection. Although there is still a lack of effective treatment for hepatitis C, a series of nucleoside analogs (NA) have been developed for the treatment of hepatitis B. NA resistant HBV mutants can accumulate during prolonged therapy and lead to the failure of anti-HBV therapy. Switching to other sensitive NAs can inhibit the emerged resistant mutants. Therefore, understanding the evolution of viral quasispecies under drug pressure is crucial for the establishment of antiviral strategy and the monitoring of antiviral process. Immune response and escape are complicated process, during which both host and virus factors may play their roles. Further understanding of the interaction and interrelationship between host and these viruses may lead to optimized prevention, diagnosis and treatment for chronic hepatitis.

Salivary gland damnification is one of the most common complication in head and neck cancer radiotherapy.Because of their unique anatomical positions,salivary glands usually receive high irradiation dose.Studies on radiation damage and dysfunction of salivary glands include injury mechanisms,relationship between dosimetrics and volumn changes and secretion,as well as prevention and treatment of damage.

Based on the discussion of the present English teaching in medical colleges and universities in China,this paper clarifies the mission and task of English teaching in medical colleges and universities and proposes that medical colleges and universities should attach importance to the education goals and needs of the department,major and students in the information age.It is believed that a scientific,reasonable and perfect English curriculum can be achieved by integrating IT into English curriculum,applying individualized teaching mode and expanding course connotation.
