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.

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.

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.

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.

A monoclonal antibody (McAb) 3H11 against gastric cancer with high positive rate, high selectivity and high affinity was obtained. 131 I Labeled McAb 3H11 was injected into gastric cancer-bearing nude mice, and the tumor/liver ratio, localization index, ID%/g could reach 8.26?1.26, 6.08 + 1.51, 11.00?2.62, respectively. Moreover, McAb 3H11 conjugated with 131 I could increase the cytotoxicity to tumor xenografts and decrease the side effects. The radioimmunoimage was carried out in 19 cases with gastric cancer, and positive image was obtained in 16 cases (84.2%). The radioimmunoguided surgery of gastric cancer was successfully done by submucous injection of labeled McAb 3H11 through endoscope. The sensitivity, specificity and accuracy for evaluation of tumor infiltrated gastric walls were 94.6%, 96.7% and 95.9%, respectively. The sensitivity, specificity and accuracy for identification of metastatic lymph nodes were 99.2% ,97.7% and 98.8%, respectively.

[Objective]To verify whether or not the modified open-door laminoplasy preserving semispinalis cervicis insert into axis is effective in preventing postoperative axial symptom and maintaining postoperative cervical sagittal alignment.[Method]Since March 2002 to December 2003,forty-eight patients underwent modified open-door laminoplasy preserving semispinalis cervicis insert into Axis,among them,thirty-two patients who were followed up for more than 2 years were included in this study.Preoperative and postoperative JOA score,degree of axial symptom,ranges of neck motion,cervical curvature index were recorded and compared.[Result]Preoperative and postoperative JOA score was(9.04?2.9)and(12.5?3.1)respectively,with recovery rate as(44.9?26.9).There was significant difference between preoperative evident axil symptom rate(46.8%)and postoperative evident axil symptom rate(18.7%),while no significant difference between preoperative and postoperative ranges of neck motion,cervical curvature index was seen.[Conclusion]Modified open-door laminoplasy is less invasive to the posterior extensor mechanism especially the semispinalis cervicis than conventional open-door laminoplasy.This new procedure is effective in preventing postoperative morbidities often seen after conventional laminoplasy with adequate decompression of the spinal cord.
