Opposite effects of miR-155 in the initial and later stages of lipopolysaccharide (LPS)-induced inflammatory response / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Although microRNA-155 (miR-155) is considered a pro-inflammatory mediator, cumulative evidence indicates that it also has anti-inflammatory effects in macrophages and dendritic cells. In this study, we identified the dramatic expression changes of more than half of potential miR-155-targeted genes upon lipopolysaccharide (LPS) stimulation; 223 genes were down-regulated and 85 genes were up-regulated, including suppressor of cytokine signaling 1 (

Effect of glutamine metabolism on chemoresistance and its mechanism in tumors / 浙江大学学报·医学版

The metabolic reprogramming of tumor cells is characterized by increased uptake of various nutrients including glutamine. Glutamine metabolism provides the required substances for glycolysis and oxidative phosphorylation and affects the homeostasis of carbohydrate，fat and protein metabolism to induce the chemoresistance of tumor cells. Combination of chemotherapeutic agents with inhibitors specific to different components of glutamine metabolic pathway has obtained favorable clinical results on various tumors. Glutamine metabolic pathway plays a role in drug resistance of tumor cells in various ways. Firstly，the dynamic change of glutamine transporters can directly affect intracellular glutamine content thereby causing drug resistance; secondly，tumor stromal cells including adipocyte，fibroblast and metabolite from tumor microenvironment would give rise to immune-mediated drug resistance; thirdly，the expression and activity of key enzymes in glutamine metabolism also has a critical role in drug resistance of tumors. This article reviews the effects of glutamine metabolic pathway in the development of tumor chemoresistance，in terms of transporters，tumor microenvironment and metabolic enzymes，to provide insight for improving the therapeutic efficacy for drug-resistant tumors.

"""The Twelfth-five"" program for the development of key medical disciplines in Zhejiang Province: past and future" / 中华医学科研管理杂志

We herein overviewed the history,achievement and plan of the twelfth-five program for the development of key medical disciplines in Zhejiang Province.We summarized the practice and characteristics of establishing of the key medical discipline in the Zhejiang Province,and a systemic survey was conducted on the effectiveness of the program.We then proposed several improvements strategies including academic training,multidiscipline coordination,and fund managements to eventually establish the new pattern of discipline development.
