According to the project of personnel cultivation in 21st century,we have increased interdisciplinary comprehensive experimental courses to intensify the practical education,optimize operating model and teaching method of experimental courses.Experimental education must be strengthened in order to culture students' creativity.

Industrial culture media for cultivation of marine microalgae Nannochloropsis oculata was optimized by using Random Design software. High eicosapentaenoic acid (EPA) content was obtained over 40% of total fatty acid, and high average specific growth rate of 0.32d -1 was obtained in cells grown in the selected Formula 1. Mass cultivation of this species was practiced in indoor open raceway ponds of 6.12 m 2 and 28.02 m 2, and in outdoor open pond of 83.50 m 2 during May and June in 1999. The average area yield of biomass were obtained at 2.77, 1.62 and 2.52 g /m 2?d, and in October, 1.09 g/ m 2?d was obtained in 83.5m 2 outdoor pond, and the harvest algae powder contained 49.50% of protein, 20.30% of total lipid and 3.00% of EPA of dry weight. With high temperature tolerant species during August in 2000, the average area yield of biomass were increased to 5.44?9.96 and 7.66 g/ m 2?d in above ponds, respectively and 2.50% of EPA of dry weight was contained in the powder. It is indicated that the industrialized cultivation of Nannochloropsis oculata rich in EPA is completely doable on practice, and the algal powder was a good raw material as single cell protein and development of EPA rich products.

Cell-cycle deregulation leading to excessive cellproliferation is an important mechanism of human tumorigenesis. CDK6 and CDK4 have been found to be significant regulators of cellcycle, particularly in promoting cell -cycle progress. Moreover, these proteins are usually overly active in most tumors and closely related to tumor development. Recently, research has confirmed CDK4/6 as prospective targets for cancer therapy. However, the mechanism of excessive CDK6 activation leading to tumorigenesis is not completely understood. Therefore, further understanding of the role of CDK4/6 in cell -cycle regulatory pathways and celldifferenti-ation is essential, as well as their overexpression in different types of tumors. This information will elucidate the mechanisms of tumor development and treatment. Therefore, this review intends to discuss the structure and biological function of CDK6, the role and mecha-nism of CDK6 in carcinogenesis, and the clinical application of CDK6 inhibitors.

False and negative information has brought forth serious impacts on doctor-patient relationship in the new media era as a result of “Broken window effect”and “Butterfly effect”.The underlying reasons are herd mentality,the public’s need to vent their discontent,the subjectivity of information distribution on the Internet and lack of proper supervision and punishment mechanism.Medical Institutions should pay special attention to the new media,leveraging it to improve doctor-patient relationship by making official voice,guiding public opinion,solving problems,and providing comfortable social environment and rational public opinion environment on the Internet.
