大学生网络圈群具有“技术空间”和“生活空间”的双重属性,实现了学校课堂场景、社会生活场景和网络空间场景的有效连接,在一定程度上推动了高校思想政治教育话语的传播。同时,高校思想政治教育的本质和资源优势也要求其必须覆盖大学生网络圈群,这是深刻把握思想政治教育话语网络圈群传播现状的必然结果。网络圈群中高校思想政治教育话语传播面临着空间上“多元场景”与“信息茧房”并存、话语结构由“宏观严谨”转向“碎片脱序”、话语资源因“信息过载”引发“信息成瘾”、话语内涵由“情感至上”转向“群体极化”等现实挑战,进而分化了话语传播的凝聚力、解构了话语体系的完整性、稀释了话语资源的吸引力、削弱了话语内涵的主导力。对此,高校应通过实现圈群内外话语联动、理性规约与利益疏导相结合、多元协作与协同引导相贯通、改善表达与情感嵌入相融合等策略优化思想政治教育话语的传播途径。

Objective: EphB4 is a member of the largest known family of receptor protein tyrosine kinases, which plays an important role in a variety of processes during embryonic development including pattern formation, cell aggregation and migration, segmentation, neural development, angiogenesis, and vascular network assembly. EphB4 selectively binds Ephrin-B2 and not other Ephrin B ligands, interaction between EphB4 and Ephrin-B2 can provoke bidirectional signaling,then can regulates cell proliferation. We focused on EphB4 for its potential role in tumor biology because of its location on chromosome 7q22, a locus frequently amplified in cancers including prostate cancer, and because of its expression in various cancers, However, little is known about the role of EphB4 in prostate cancer development and *** the study was mainly investigate the expression of EphB4 in human prostate cancer and their relationship with tumor lymphangiogenesis and metastasis. Methods: Expression of LYVE-1,EphB4 receptor was examined with immunohistochemistry in tumor specimens from 40 prostate cancer cases and 10 benign prostatic hyperplasia (BPH) *** vessel density (MLD) was counted according to the result of LYVE-1 staining. Results: Using immunohistochemical techniques ,we showed that the EphB4 receptor was significantly higher in prostate cancer Compared with benign prostatic hyperplasia ( BPH ) ,and EphB4 receptor was produced significantly in increased amounts in human prostate cancer of greater Gleason score compared with lower Gleason score tumor group. there also appeared to be a trend towards increased expression of EphB4 receptor with higher grade disease. Compared with EphB4 negative group, the MLD was significantly greater in EphB4 positive group. Conclusion:The expression of EphB4 receptor might contribute to tumor lymphangiogenesis and tumor invasion as well as metastasis in prostate cancer. Therapies that target EphB4 may prove to be successful in preve

Objective: This study aimed to use a systematic approach to evaluate the current utilization, safety, and effectiveness of cell therapies for neurological diseases in human. And review the present regulations, considering United States(US) as a representative country, for cell transplantation in neurological disease and discuss the challenges facing the field of neurology in the coming decades. Methods: A detailed search was performed in systematic literature reviews of cellular‐based therapies in neurological diseases, using Pub Med, web of science, and clinical trials. Regulations of cell therapy products used for clinical trials were searched from the Food and Drug Administration(FDA) and the National Institutes of Health(NIH).Results: Seven most common types of cell therapies for neurological diseases have been reported to be relatively safe with varying degrees of neurological *** a series of regulations in US for cellular therapy was summarized including preclinical evaluations, sourcing material, stem cell manufacturing and characterization,cell therapy product, and clinical trials. Conclusions: Stem cell‐based therapy holds great promise for a cure of such diseases and will value a growing population of patients. However, regulatory permitting activity of the US in the sphere of stem cells, technologies of regenerative medicine and substitutive cell therapy are selective, theoretical and does not fit the existing norm and rules. Compiled well‐defined regulations to guide the application of stem cell products for clinical trials should be formulated.
